[I-3] Connectivity Between the Harvard School of Public Health & Cyprus International Institute for the Environment and Public Health


Harvard University, USA and Nicosia, Cyprus

Prescription of the Types and Pervasion of Connectivity by Mikael Powell

A. Introduction
Marc Andreessen, a co-founder of Napster, said “As bioscience becomes more computational and less about wet labs and as all the genomic data becomes easily available on the Internet, at the same point you will be able to design vaccines on your laptop”[1]. Thus is the destiny of technology in pursuit of advancement in health education. My research concerns the interrelationship between esteemed educational health facilities and how technology enhances the affiliation. The purpose of the research is to discover ways to connect the Harvard School of Public Health in Boston, Massachusetts and the Cyprus International Institute for the Environment and Public Health in Nicosia, Cyprus. This work analyzes the phenomenon of connectivity (and how it is affected by pedagogical models) with regards to the characteristic of being connected in a social, personal and operational way, and offers requirements for the new technology. It does not focus on technological detail, rather, it examines the broader scope- the more abstract themes that are relevant to this analysis with expectations that they will be personally applicable and prescriptively effective. Moreover, this document reviews criteria without deference to a particular pedagogy as it allows for ‘practice-based’ teaching methods for public health as well as traditional instruction. The Cyprus International Institute for the Environment and Public Health, sponsored by the Cyprus government, is administered by the Harvard University School of Public Health. Through research and communication, it aims to be a catalyst in the advancement of regional public health. Programs in Boston and Cyprus promote contemporary research, and the Cyprus initiative is positioned to develop local proficiency in environmental health and ultimately spur innovation to benefit the region. The education and information components provide high quality training and renowned professionals to benefit its students, peers and lay audiences through in-person interactions and various communication media.
The Cypriot initiative expands the reach of the Harvard School of Public Health – faculty members share responsibilities between the institutions and likewise, students cross-register between the programs. This “brick and mortar” facility heralds a significant milestone in the history of the Harvard School of Public Health as it is an official outreach with substantial permanence. The initial construction will include classrooms, research laboratories, offices, a library, an auditorium, a cafeteria and housing (to accommodate the high volume of visitors). “Identity, comfortable transition of the Harvard travelers between the two places, integrated digital media for daily interaction, and respect to the local traditions” were the primary concerns outlined by Professor Spiro Pollalis in a studio tasked to propose the design of the facility,” In order to create an environment that supports ‘the culture of innovation’, people must be able to directly interact on a casual as well as formal basis[2].”

B. Pedagogical Models and schools of Public Health
Several instructional approaches will be employed throughout the facility including traditional methods of lecturing, discussion, demonstration and hands-on approaches and contemporary practice-based educational processes. These offer technological opportunities for enhanced interaction within the classroom, between the two facilities and to the outlying public. Lecturing, typically used as the primary component in a structured presentation provides information or constructs an instructional framework. Discussion aims to accentuate the relationship between the instructor and participants within an identified topic, as well as share experiences between participants in a structured (whether prescribed or informal) environment. Demonstrations offer direct learning experiences and hands-on interactions and slows for maximum opportunity to learn multi-dimensionally. Participation can be enhanced through connectivity that spans distance and provides a venue for real-time interactions.
Practice-based methods can be described within the context of several principles which aim to integrate teaching and practice through a constellation of varied interdisciplinary activities to facilitate learning partnerships between students, educators, researchers, practitioners and the public. Great emphasis is placed on learning through actual involvement because “learning from experience in public health has civic roots, as exemplified in volunteerism and community service. The philosophy of experiential learning is that people learn most effectively through direct, hands-on experience, as long as these experiences are well-designed and facilitated”[3] within a program of experiencing, reflecting, planning and application.

C. General Manner of Connectivity
There are several ways in which innovative technology can support connectivity to enhance inter-classroom pedagogy, intra-facility communication, security, broadcast capabilities and shared presence. In addition, technical ways of connecting remote laboratories should involve an exchange of data that is certainly within the grasp of existing technology, but is ‘supra’ to side-by-side interactions. In addition, there are cultural ways of connectivity that are thematic or even textural. Since the facility will be occupied at the end of this decade, then some technology is unproven currently, indeed, it may be wholly premature to assign specifics products at this time. Thus it is important to map the requirements of technology when existing systems are inadequate or emerging technology untried.
This is the first initiative by the Harvard School of Public Health for a remote presence; therefore these concepts can be incorporated in the architectural design of the building. This research on connectedness will set the standard for the Harvard and undoubtedly other corporations with satellite offices.

D. Being connected Socially and Culturally
Within a global community perhaps technology, education and health are the building blocks of a depressed society aspiring to increase their status in the world[4] . This is abundantly evident in humanitarian initiatives by countries with the highest gross national product. Less developed countries, vie for that inter-relationship to boost their quality of life. That connection, whether as partner or patron or sponsoree is conceived and lived in a political environment quite aware of its boundaries. But being connected in a social context in regard to these issues can proffer an occasion for global professional allegiances, - a humanitarian society of health professionals philosophically bound by ethics, shared goals and access.
Connectedness in access is a significant utility to bolster social and cultural awareness. In the professional field, shared information is often reliant upon libraries and research depositories. Harvard University is connected to one of the largest library systems in the world. Library networks are strengthened and students and practitioner are empowered, when provided the opportunity to review a cadre of rare and sophisticated materials that would have been previously unavailable. Such unfettered exchange is not without forethought. Consideration must be given to the operational language of the system and interfaces with allow for cataloging and access of foreign language materials. Being socially connected may involve acquisition of translation services. And certainly, the network must be able to handle increased systems activity. The prerequisite to being socially and culturally connected is user training, which to be effective, must allow for the educational and cultural background of the individual in recognition of the political inequitabilities of their environ. As network connectedness is realized in mobile applications through advancements in nanoscience and power delivery, then profound global integration can follow. Geoffrey Kirkman of the Center for International Development at Harvard University stated ” The ability to remotely monitor environmental and health conditions, engage in project-based learning at a distance and effectively communicate where there once was virtually no communication at all could have revolutionary repercussions on the development impact of fieldwork”
In a network of connectivity, there is no isolation. Therein lays the basis of a humanitarian culture. Historically, in the United States, in the early 20th century, tracking through towns and neighborhoods was a network of boulevards, streets, and sidewalks. Daily pedestrian engagements were the norm. But due to several reasons, including the impact of automobile travel, federal regulations and standards and post war familial dynamics, a market has developed for “exclusive ‘communities’ where only a certain class of person ….is deemed worthy of sharing the streets and spaces of the neighborhood”[5] Actions to segregate public streets into gated communities or cloisters are common. Indeed, in many locales strangers are looked upon with disdain for daring to linger too long on a public sidewalk or “encroach” along a public street. Such feelings are an anathema to the spirit of social and spatial connectivity whether in the physical world or within cyberspace. Moreover, when one considers internet connectivity for social mobilization, whether concerning regional environmental issues or ones of discrimination, it was found, that it can be used to foster a sense of belonging and perhaps with proper administration it can be used to build a collective identity for social movements.[6]
Overseas, much research has been conducted in regard to participation in the Parliament through internet connectivity, undoubtedly, the Harvard initiative will be linked oftentimes in a dialogical network. Studies in England conclude that this condition “can be achieved through internet connectivity and if effective, can empower the institution. Such was the case in the Parliament study where they found that on-line consultations provide a space for inclusive public deliberation”.[7]

E. Being connected in a Personal way
The notion of individual connection to a public network, whether in a social, business or governance context requires considerations for responsibility and emotionality. “When you feel connected to everything, you also feel responsible for everything. You can not turn away. Your destiny is bound to the destinies of others. To seek enlightenment is to seek…the taking up of burdens. [8]” Such is the internal agony of being connected to everything in the universe with degrees of separation calculated in nano-seconds. Each person in their own way struggles with their shared responsibility for the actions of the network entity.
Innovative mobile technologies serve to keep us always connected to the network, whether for GPS security reasons, or business telecommunications, or even for scholastic access. Not surprisingly, there may be personal consequences to always being tethered. Some ardent producers may develop a problem in learning to “turn it off”. Psychologist, Martin Factor, says that "always-on connectivity may create anxiety when we [do] disconnect”.[9] When one considers the opportunities for connectedness between The Harvard School of Public Health and the Cyprus International Initiative it may not be hard to reach overload situations. On the other hand Linda Stone, a former Microsoft vice president, has coined the moniker "continuous partial attention" which describes the quality of an individual developing a main and peripheral focus, which she offers as a useful occupational tool. Stowe Boyd, the president and COO of Corante surmises that” Most think of it as a disorder. However, CPA is the state of mental blurriness thought to be induced when information is constantly pouring in from multiple sources. It can be a reasonable strategy for dealing with a sped-up world, but it requires shifting the measurement of productivity away from the individual -- like 'IQ' tests -- and looking at the productivity of connected groups. More than ever, we are connected beings. Now we have to figure out, as a society, when it's proper to ask someone to disconnect--and in effect, to cut off a part of them.[10]
Some surmise that being connected in a personal way extends beyond the psychological to the psychic realm. Carl Japikse said “Every time you think of someone, you are psychically connected to them, even if they are miles away. This linkage occurs even if you have not met the person, so long as there are enough elements known to connect you. "Once he focuses on you (even if he did not know he was doing so), he began examining elements close to you. In essence, a portion of his consciousness was exploring your habitat…[11]."

F. Being connected in an Operational way.
Functionally, the byproducts of informational connectivity, or interaction, can be described by operations of communication and collaboration whereby the former is an exchange of information to satisfy that end and the latter occurs when two or more seek to produce a common expression. Oftentimes collaborative efforts are combined with strict communication e.g. a collaborative authoring system (collaboration) equipped with a chat feature (communication).[12] This is important when distinguishing the need for communications connection with the opposing location in congruence with collaborative enhancements. Discernment is required to allow facilitation, in most respects, rather than obtrusive oversight. Whether in this cooperative academic setting or in the commercial businesses, consideration must be given to provide the appropriate connection amenities to accommodate the work environment and save costs.[13]
Understandably, laboratory education is costly for universities, both in construction of specialized facilities as well as innovative equipment and its operational needs, training and maintenance. A contemporary method is that of the “shared” or “connected” laboratory that is virtual and internet based. “The virtual laboratory utilizes real equipment distributed among multiple universities from which remotely located students can perform experiments. The software solution is a multi- user, client-server architecture. Implementation includ[es] video, chat, archiving, and specific hardware and software platforms”[14]. Specific experiments are coordinated between each institution (time zone differences can favor full utilization). A lesser technological version of this would be to utilize common testing software that allow data stream either in a synchronously or asynchronously transmission.
Likewise, in utilizing operational connectivity, the University of Western Australia has been on the forefront in developing and testing new technologies for student learning using the Internet to develop new styles of education using simulation, theory, and laboratory equipment[15]. Results for interactive television for distance education have been abysmal. Currently, the technology involved can be restrictive to the professors’ pedagogical methods and results show that students are less engaged. The compromises made in the quality of teaching and learning must be carefully considered when evaluating options for conventional face to face instruction.[16] Innovative advances in the development of interactive multimedia courses and experiments like the virtual classroom[17] seem promising for the shared, distance education. And, trends in mobile telephony in the UK and other countries have been more proposed for inclusion in the classroom. “Current work in educational technology may contribute toward a move towards using mobile telephony in education as a potential enhancement, and minimizing the nuisance effects and stigma in the process.[18]

H. Conclusion
Our connection to the world, through technology, is a multi-dimensional link. There are personal, social and functional considerations to be weighed when one considers relationships within the educational environment, between facilities and to the greater public. Certainly, deference to security is in order, as the Cyprus Initiative in its first stage will have rooms occupied on a 2-hour basis. Cultural connections homeward and familial relationships are essential to maintain as all doctoral students will spend 50% of their time in Cyprus on research related to Cyprus and the region and conversely a contingent will be studying in Boston. On an operational level resource efficiency requires that a proper network be maintained within facilities - indeed between teacher and student. So this phenomenon of connectivity is crucial to take into account as we incorporate innovative technology to enhance the teaching and dissemination of information at these facilities.

[I-1,I-2] The Purposes of Schooling by Mikael Powell




THE SCHOOL PURPOSE BIN

I. ACKNOWLEDGMENT
Compiled and written by Mikael Powell
II. GUIDE TO READER
My artifact exemplifies the public elementary school options in Dallas, Texas. I have reviewed the Mission Statements of almost every school in the district and shown them within the operation of either DISD or a public charter school board. I have identified the type of delivery system for this organization and envisioned other delivery systems. I have created a wood model 2”deep, 24” wide by 24’ long to illustrate the concepts. This project focuses the national conversation of different purposes for education to a specific locale. I had assumed that there was a loose unity in the mission statements of the 127 elementary schools in the district, but rather, I found a plethora of options---- if you live in the right place.

I looked to this assignment as an opportunity to study education from a different angle – to dispassionately review the players and systems as an outsider vying to for positive change.
Therefore, if one looks at education as a service, and the teachers and infrastructure as a process, why could not the purpose bins be interchangeable? Wouldn’t that bring about better efficiency and choice? Anyway, the following is my exploration of the elementary schools in Dallas.

III. ON A MISSION
Presently, Dallas Independent School district is the 12th largest district in the United States serving 161,000 students. I focused on the 127 elementary schools and 17 elementary charters schools to read each mission statement or motto and determine which purpose bin they fit in. I read all but about a half-dozen. I categorized them in the following bins: Academic, Social Change, Economic Utility, Socialization, Individual/ personal growth, Democratic, Combination (mainly a mix of Academic and Personal growth) and None (meaning they had either no mission or a slogan like “Success!”). Many schools in this category touted a “safe and nurturing environment in which to learn”. It is interesting to note that four schools listed the State standardized test in their mission statement and two of those had school motto’s which included recognition categories i.e. “A School to be ‘Recognized’ and Together we can reach ‘Exemplary!’”. Several schools used a version of “If it’s to be*(e) it’s up to me!” for their motto. The strangest slogan was “Education unlocks the hidden rooms of the mind” – the motto of the Ann Frank elementary school.

I compiled the totals of each group and created symbols for each purpose bin. Descriptions of the symbols follow.

*This is the motto of the Buckner Elementary Bees.

IV. Purpose of Education SYMBOLS
A Democratic Purpose (green square) –Educating the young in support of democracy may be leadership’s highest calling - John I. Goodlad

This purpose supports the notion that in order for a democracy to function, an intelligent citizenry is needed. Schooling is therefore the institution that molds civic leaders.
Advocacy groups - Forum for Education and Democracy, which attempts to raise the level of dialogue about education and particularly the democratic purpose of schooling and “to bring debate back to local communities nationwide”[i]. The IEI, a nonprofit advocacy group looks with disdain upon high stakes testing and laments that placing the task of social change on schooling is a “serious mistake”.

A Socialization Purpose (red triangle)–
The socialization purpose states that schools are to teach persons to live in society and learn cultural norms. This purpose carries an importance in integration discussions, whether voiced or not. Many aspects of socialization in public schools have been studied, i.e. social class setting and reproductive and non-reproductive knowledge[ii].
This purpose is anathema to Home Schoolers who contest the assumptions that Socialization is necessary, good, or to be properly socialized “children must spend large amounts of time with their peers[iii]”.

A Economic Utility Purpose (brown rectangle)- “Economic utility tells children "If you will pay attention in school, and do your homework, and score well on tests, and behave yourself, you will be rewarded with a well-paying job when you are done"-Neil Postman[iv]

For the purpose of this study, I am reviewing elementary schooling. Obviously, there is a need for ‘vocationalism’ in the high school setting. Many municipalities, Ontario for instance, have stated that jobs are not the main reason for elementary school, rather it is to instill worthy values[v]. One cannot argue though that in many third world countries and underdeveloped regions of the United States, the basic skills learned in school are the foundation for securing entry-level low wage careers.

A Social Change Purpose (light green long triangle)-
The purpose of schools is to awake the masses to social progress.
The Elementary and Secondary Education Act of 1965 was a foundation for President Johnson’s Great Society. His program aimed to provide resources to combat illiteracy, unemployment and crime. His goal to close the literacy gap is still sought after today.
An Academic Purpose (blue half-circle) - The purpose of school is to develop skills to reason, create and imagine.

Certainly, the Academic purpose is one that can be stretched to include many reform initiatives. ‘Excellence” in education can imply mastery of a state high stakes test and it can imply individual growth – especially in regard to gifted students. Many charter schools tout their academic aspirations and some have fallen short with academic plans for students with disabilities. Dr. Martin Luther King, Jr. wrote, “The function of education is to teach one to think intensively and to think critically. But education which stops with efficiency may prove the greatest menace to society. ... We must remember that intelligence is not enough. Intelligence plus character -- that is the goal of true education[vi]."

A Personal Growth Purpose (yellow circle)- The purpose of schooling is to meet each child where he is an advance him to his potential.

To those ends these school utilize an ‘ILP’ (Individual Learning Plan) for personal growth. This quasi-contractual document to prescribe instruction based on academic, social or behavioral needs may be fashioned similar to the state required IEP for students with disabilities. Of course, this concept is not new or exclusive to this purpose of education. Personal growth plans, especially when connected with students of learning differences, have been construed to enable ‘cultural’ assessment instead of individual assessment and even economic utility practices. Moreover, care must be taken to coordinate individual growth with state mandated achievement results.

V. MISSION RESULTS

My research concluded that 35 schools had a democratic purpose, 25 academic, 21 had a combination of several missions, 19 personal growth, 12 socialization, 4 economic utility, 4 social change and 49 None (or vague slogan).

I observed that Dallas Independent School district is a large organization that is shaped to provide infrastructure and resources for several elementarily schools. While many of the schools share the same general purpose for schooling, presumable each principal creates their school’s unique version and supports its implementation through use of facilities, hiring and schedule. Not surprisingly the district mission is to “to prepare all students to graduate with the knowledge and skills to become productive and responsible citizen” or basically to be all things to all people. Although I know there are arguments for decentralizing programs to increase local control, I suspect that efficiencies can be gained by utilizing concepts of Mass-customization of services. The best way to minimize costs while maximizing individual customization [providing different purposes at district schools] –is by creating modular components that can be configured into a wide variety of services.[vii].

VI. DESCRIPTION OF THE DELIVERY METHODS – Mix Modularity
See Model Section “E” - The DISD, at it’s kindest assessment is an example of providing services through a mix modularity mode. This amorphous organization functions to provide an array of distinct services. As the services change the organization changes. To attain efficiencies with this model , however, the district has to develop a ‘recipe’. Consider an ice cream cone vendor. They are equipped to handle all the customers in a day, but they have relatively few components – ice creams, sprinkles, cones etc… Yet they are made efficient by the strict recipe that allows them to stock the ingredients and make unique Mocha- Sprinkled cones in mass.

VII. DESCRIPTION OF THE DELIVERY METHOD- Bus Modularity
See Model Section “C” -Another method would be Bus Modularity. In this example DISD would provide a framework to which each purpose could be interchangeable. A clothesline in which garments can be pinned anywhere along the rope is a good example. An efficiency in this system would be that resources could be split between the bus (infrastructure) and the service (curriculum, instruction). Creating an adequate environment is always apropos; tweaking the curriculum - even incremental revisions can be always progressive. One need not throw money into a school infrastructure that merely had a good program.

VIII. DESCRIPTION OF THE DELIVERY METHOD- Component-sharing [left] and Component-swapping [right] modularity

See Model Section “D” - Component sharing and swapping methods require that the school purpose be “packaged” and the degree of ‘fit’ needed is handled by the chosen method. In the sharing mode, a school would opt for an Academic Achievement orientation by excising the existing program and embracing the new one within it’s present framework. Component swapping would entail appending the new onto exiting structures. An example of the component sharing system is way cars are produced in America. The chassis is the same for many car styles. Efficiencies for the school district would be attained through economies of scope.

IX. DESCRIPTION OF THE DELIVERY METHOD- Sectional Modularity

See Model Section “F” - Sectional modularity creates a series of schools by modulized components. It is the Lincoln log system. The district would create a set of Purpose types, curriculum/instruction types and facility types that could be interchanged throughout the district. This model would allow for intensive on-going research and revision on each type. Schools would have the option to arrange components as they wish.

X. Reflection –
I experienced this project as a way to look at how services are provided thorough the school district in the hopes of provident a more efficient system.

It is apparent how very difficult it is to reform education! Everyone has a different opinion for the purpose of education. Several areas of reform (curriculum, instructional staff, resources, political nerve) influence the other. High stakes standards without adequate resources affect the overall system and have resulted in four of our elementary schools including test proficiency in their school mission. Moreover implementation is as important as the actual concept itself. I learned that there are many successful small-scale reforms, but taking them to scale is a hard, or impossible in some instances.

At one time I assumed that charter schools will definitely be the best avenue for reform, but now I have new respect for other vehicles, other purposes for schooling and other professionals that are earnestly trying to make the system better. Moreover, I am not discouraged.

Shape Memory Wire Experimentation


Shape Memory Wire Experimentation
By Dido Tsigaridi & Mikael Powell


Since the early 1930’s researchers have observed an unusual temperature activated shape-changing phenomenon in various alloys. While the effect seemed hopeful to provide physical movement for machinery, the metals themselves proved problematic for mass application. Early alloys were either too expensive or too toxic. Modern researchers continue to test alloys in regards to their efficacy and unique transformation characteristics. Our particular interest is not in the metallurgy, but rather, the variables inherent in the shape-changing phenomenon. We will therefore review the material specifications and qualities used in our research, test the variables and offer concluding remarks.

MATERIALS USED FOR OUR EXPERIMENTS
Shape memory alloys are materials whose microstructure changes with an input of thermal energy. Although the phenomenological result may suggest that shape memory materials are energy-exchanging, they are actually property-changing.[1] Thermal energy is not transformed into kinetic energy, as one may think by observation. Heat enables an alteration of the material’s microstructure through a crystalline phase change.
The material we used for our experimentation is NiTi (Nickel and Titanium alloy). NiTi can be temperature-activated by direct heat or through resistance to electrical current. Quite simply, the material is “programmable” at very high temperatures and formable when cooled. Upon returning to its warm, resilient state, it "remembers" its programmed shape and returns to it - applying force against anything it its way.[2] Moreover, the manufacturer purports that NiTi is very resilient, lightweight, non-corrosive, biocompatible and wear resistant. Many engineers specify nickel titanium for two qualities: shape memory and super-elasticity.[3] These two characteristics distinguished NiTi from ordinary metal blends in their first scientific publication of 1963.[4] For our experimentation three different shape memory alloy types were used. They are bar shape, electric piston assemblies and NiTinol wire of circular cross section. Their specifications are as follows:
a. Bar Shape #SMA-5A, 0.023” x 0.074” x 5”, by Shape Memory Applications, Inc.
It is a Nickel-Titanium Alloy (Ni -55.5%, Ti -Remainder, Fe -0.05% max., C -0.05%max., H -0.05% max., other trace elements <0.01h0.005 title="" style="mso-footnote-id: ftn5" href="http://www.blogger.com/post-edit.g?blogID=17188973&postID=113942546002516422#_ftn5" name="_ftnref5">[5]
b. Electric Piston by Mondo-tronics Inc.
It is an all-electric linear actuator shape memory wire mechanism that shortens in length with great strength and speed. Its optimum voltage is at 4.5V.
c. HS-6 Nitinol Memory Wire, 0.0297” diameter, by Educational Innovations Inc.
It is a Nickel-Titanium Alloy with a transition temperature between 30oC and 50oC. Its optimum voltage is at 9V. The temperature required to “set” a new shape is 500oC.

QUALITIES OF THE MATERIAL
Shape memory is a design function of the material's temperature. Nickel titanium undergoes a phase transformation, as the material is heated or cooled through its temperature transition range. A NiTi spring with a transition temperature of 42 o C reacts like a typical spring above this temperature in its austenitic state and is flaccid in its martensitic phase below 42 o C. It recovers its shape with significant forces if the temperature rises above 42 o C. It is important to mention that the temperature at which the phase transformation occurs is adjustable over a wide range. Thus, it can be adjusted to approximate body temperature or even extremes in excess of 150oC or below -100 o C.[6] NiTi wires respond to a temperature range of -25oC to 75oC.
The manufacturing process starts with the alloy being heated to 500oC (or much more for specific alloys) which aligns the atoms into a compact and regular pattern. Workers can form the alloy into the desired shape using many standard metallurgic techniques (i.e. cold forming). NiTi manufacturing is more complex because titanium is very reactive. An inert environment is needed to melt the material and similarly heat-joining methods are problematic. Cold working provides a very fine-grained material, which allows for the manufacture of fine wire.
Super-elasticity describes the material's ability to recover from large amounts of strain. A NiTi component can fully recover from strain values up to 8%. Stainless steel, by comparison, will withstand only 2% strain. The super-elasticity of NiTi allows it to perform functions that would permanently deform other materials.

VARIABLES STUDIED IN THE FIRST STAGE OF EXPERIMENTATION
As a first step in our bibliographical research and experimentation with the shape memory alloy, we tried to identify the different variables which influence the phenomenological effects of ‘memory’ and ‘movement’. Being aware that the variables for the transformation of shape memory alloys from the martensite to the austenite structure are numerous, we selected to focus only on five parameters and examine the field of their influence.[7]

“Temperature influences the shape and the speed”
The fact that these materials change in relation to temperature is a characteristic attributed by default to this category. Thus, our experiment investigates the way temperature influences the speed with which the shape transformation takes place.
Experiment 1 – Shape Memory wire electric pistons- researching voltage to reaction time. In this research, we used a component spring assembly. The electric pistons are 8.5 cm long when the interior SMA spring is in the fully extended martensitic position. A standard exterior overforce spring extends to protect the device from overstrain. The austenite state of the alloy wire is pre-designed for the spring to be 6.2 cm in the contracted position. The spring remains pliable below the activation temperature. The energy changing process is actuated by heat generated by electric current.

One end of the piston is fixed to the wall and the slider is deformed to a specific length. Six trials were conducted, each with a different voltage to the piston. Time is calculated from application of current to slider return to the first position. (Please see Exhibit 2 in Video Appendix).
In conclusion, we found that the action required 50:04 seconds with a 3 Volt charge; 18:22 seconds with 4.5 Volts; 17:20 seconds with 6 Volts; 16:05 seconds with 7.5 Volts and 15:11 seconds with 9 Volts. In testing heat to reaction time, please note that there is a dramatic difference between the length of reaction time and voltage at 3 volts and 4.5 volts, but beyond those levels the deviation is minimal through our maximum voltage of 9 volts. The relation between voltage and speed is not linear. (See Exhibit A)

“The wire diameter influences the minimum bend radius and the force released”.
Minimum bend radius describes the smallest bend a wire can make without risking damage. Sharp bends or kinks should be avoided because they can overstrain and weaken the wire. As a rule, a wire should not be bent tighter than fifty times its diameter. The following table shows the linear relation (inversely proportional) between wire diameter and minimum bend radius for some common wires (See Exhibit B). Thus, the thicker the wire, the less it can be bent.
In addition, the force produced by shape memory wires when moving from a martensite to an austenite phase is related to the wire diameter. For greater strength devices may use many wires in parallel. The following table shows the forces generated by groups of wires of various sizes, as well as how much weight they can lift and the total power needed to activate them (See Exhibit C). [8]“Application of heat affects reaction speed and fatigue”
The property-changing phenomenon does not occur at a uniform rate. After heat is applied in the martenistic state, there is a distinct series of reaction rates. Older experimentations show that transformation starts with a small speed, then accelerates and is finally accomplished slowly (See Exhibit 10 in Video Appendix)[9]. Although numerical data was not collected in order to document this observation, it is worth remembering that speed is not independent from the time that heat is applied to the shape memory wires. Fatigue is a complicated issue that occurs from a variety of reasons.[10] Educational Innovations Inc. instructional literature states “do not heat the wire more than is necessary to release the tension”. From our experience, the wire needs to cool right after its transformation from martensite to austenite phase. Heating longer while restraining its movement may cause “training” to a new shape even if the heat was not at the normally required level.

“Selective zone heating influences the speed and the trajectory”.
Many manufacturers of shape memory wires propose activating the material with a hairdryer or a pot of hot water. They assume that the wire should be uniformly heated for maximum effect. (Please see Exhibit 1 in Video Appendix). Our experience has informed us that heating particular zones of the wire exhibit different effects.
Speed is highly influenced by the point of heat application. We noticed that if a straight wire with a bend in the middle were heated close to the bend, it would immediately go back to its straight position. If voltage is exerted to its edges, away from the bend, it will take much more time to go back, or it may never reach the austenite shape. With this in mind, we did some experimentation to explore the trajectory a wire follows going from shape ‘A’ to shape ‘B’. We selectively applied heat to zones along the wire. Also, we introduced an additional parameter to our experiments: one fixed point. We tested the wires with a fixed point in the middle and on the end.
Experiment 2 - 2D Selective zone heating – Mode I - Graphically charting path of the ends and intermediate points with fixed end point. Many experiments have been conducted with uniform heating. For this experiment we wanted to study selective heating. The Nickel-Titanium alloy bar stock was pre-set in the austenite state to be linear. A 7 ½” length was deformed in the martensitic state to have two opposing radius bends. Direct heat application was used.
We constructed a neutral background to accept the travel indication. Different colored acrylic paints were applied to the SMA wire at each endpoint and the centerline of the radius. For Mode I, the end point was fixed to the background. Heat at 204 degree C (400 degree F) was directly applied systematically to each zone. We charted the path of the points along the shape to the austenite conclusion. (Please see Exhibit 3 in Video Appendix)
In conclusion, we noted that selective heating changes the trajectory of points along the shape as well as the culminating shape. The order of heat application determined the distinct route of each point. Also, heat application near the fixed end of the wire substantially effected the movement at the opposite unfixed endpoint. The length of path is greater the farther the point is from the fixed end. The zone heating method allows the wire to maintain both martensitic and austenitic states contiguously. (Please see Exhibits D -G)
Experiment 3 - 2D Selective zone heating – Mode II -Graphically charting path of the ends and intermediate points with fixed center point. This experiment was similar in scope to the preceding one except the center point (in lieu of the end point) was fixed to the background. (Please see Exhibit 4 in Video Appendix). We noted that the closer the heat application to the fixed center point, the less erratic the path and distance of the point movement. Also, as with the previous experiment, the order of heat application determined the distinct route of point. (Please see Exhibits H -K)
“Re-set ability is dependant on an external or counterbalanced force”.
Apart from the one-way shape memory wires (to which we refer in this paper as SMW) there exist also the two-way shape memory alloys (TWSM). In the TWSM change occurs upon both heating and cooling. In the cooler temperature, a TWSM can be easily deformed from a state ‘A’ to a state ‘B’. When heat is applied, the TWSM goes back to state ‘A’, similar to a simple SMW. After cooling again though, it “remembers” the ‘B’ state and returns to it.[11] Since we did not use TWSM in our experiments, we examined different ways that a SMW can acquire a re-set ability.
The obvious solution to have re-set is to apply an external force. In our experiments this would mean either to deform again a wire by hand or to pull a piston. However, we were more interested in finding a way to create a counterbalanced force, which would act automatically and would re-deform the shape memory material. We tested this in two different experiments.
The first experiment involved pistons, which were alternately activated to reset the action. Two electric pistons (all-electric linear actuator SMW mechanisms) and a 25w, 120v 60Hz device were used. The pistons were connected together and systematically activated at 7.5 volts. When voltage was exerted to the deformed one, it was going back to its primary position by pulling (deforming) the other at the same time. (Please see Exhibit 5 in Video Appendix)
The second experiment used the same principal but, instead of two pistons, one piston and a weight created the system. A balanced mechanism was produced. Each time current was exerted to the piston, it raised a piece of steel. When the current was off, the steel pulled back the piston because of its weight.[12] (Please see Exhibit 6 in Video Appendix)
In conclusion, we should mention that a system can be alternately activated to reset an action. Many SMA components need to be reset to their first state by mechanical means. I is usually a bigger and inelegant action. Our effort was to lead this part of our research in a path where the reset phenomenon could be developed to allow for a self-perpetuating cycle without adding many mechanical parts.
THE SECOND STAGE OF EXPERIMENTATION
For this series, we built upon our previous experimentation with shape memory wires. Previously we studied the variables such as time, heat, bend radius, zone heating and reset ability. This time, however, we are confining our research to the variable of direct heat to various zones of the wire to experience phenomenon in three dimensions. Our final project is not an object; rather it is an armature to support different applications and their distinct properties.
After reviewing our previous experimentation and research, we compiled the following chart to illustrate the variables employed in our final project. This table shows the interplay between fixed parameters and both independent and dependant variables in the new equation we established.

The temperature transferred to the wires is fixed and produced by a 12 Volt current. The diameter of the wires used was chosen to be 0.0297” so as to be thin enough for tight bents, but thick enough for high force. The heat application time is an independent variable which will change upon the user’s wish. The reset ability will be established either by an external force or by a self-deformation generated according to the heat application time (dependant variable). Finally, selective zone heating is meant to be another independent variable. The zones of heating will be pre-selected, but the way of their alteration for the production of the effect will be manipulated by the user.
For the final project we moved from the single shape memory wire, and the 2D plane of its movement, to a net of wires, and the 3D plane accordingly. Three experiments were carried out before moving to our final step. The first experiment considers all the new variables, but is still in a 2D plane, while the next two are in 3D. A difference between the 2D and 3D experiments lies in the fact that the 3D tests do not have any fixed points. The wires are free to move in a floating surface and restraining forces are exerted only because of the friction or the weight of the system. In contrast, in the 2D experiment each wire of the parallel system of wires has one edge fixed, as described below.

First Prototype -2D Selective zone heating (heat applied linear array to manipulate fabric sculpture)
The nickel-titanium alloy (Nitinol) wires (.0297” d.) were pre-set in the austenite state to be linear. Six 12” long wires were deformed in the martensitic state to have five alternating 1” d. radius bends each. Direct heat application was then used alternatively in the different bents to create a visual effect. (Please see Exhibit L, M)
More precisely, a wood frame was created to accommodate the wires. The wires were put in a series. A synthetic yarn woven fabric shroud was placed over the wire assembly. A 25w 120v 60Hz device was used to apply heat which was directly applied randomly to each zone of the wires.
As a result of this procedure, we noted that selective heating in random sequences reformed the shape of the fabric in various ways, through different speeds and in a variety of angles. The gentle visual three-dimensional effect produced, resulted only by transformations of the wires in six XY planes. (Please see Exhibits N - O)

First Prototype - 3D Uniform heating (SMW grid woven through cotton fabric)
The nickel-titanium alloy (Nitinol) wires (.0297” d.) were again pre-set in the austenite state to be linear. Eight 8” long wires were configured in a grid pattern and adhered to a gauze sheet approximately 9” wide by 9” long. The gauze was able to move freely in the table and the only force applied to it was the one of its own weight.
More precisely, the shape memory grid (XY), which was attached to the gauze, was bent in the Z axis so as to create an uneven surface. A hair dryer was then used to bring the system back to its first flat condition. The experiment was repeated three times. The second time a small ball was used to indicate the sheet transformation of the gauze by its navigation on the surface. The third time the sheet was deformed in a specific pattern, symmetrically, to attest our hypothesis that the way of its restoration can be predicted if the first shape of deformation is controlled (See Exhibits P- Q).
These experiments served as a first prototype for our final project and helped us organize our grid of wires. They were also useful in examining the type of the wires connection to the fabric and in deciding to have them free-floating in a frame instead of selecting fixed points, as we did in the previous experiment. (Please see Exhibit 7 in Video Appendix)
Second Prototype -3D Selective zone heating (single circuit SMW grid attached to synthetic membrane)
The nickel-titanium alloy (Nitinol) wires (.0297” d.) were once again pre-set in the austenite state to be linear. Eight 8” long wires were configured in a grid pattern and adhered to a polyurethane membrane approximately 9” wide by 9” long. The corners of the membrane were attached to a cardboard frame with elastic bands. Electrical wiring was installed to provide one circuit to the shape memory wire grid. (See Exhibit R)
More precisely, the poly flat assembly was deformed to provide radiuses in the Z-axis direction. A ball was employed to show more effectively the change in the surface planes. The electric circuit was powered and attached to a specific bent of the surface. The effected bend went then back to its straight shape, influencing the surrounding, and the ball shifted position. (Please see Exhibit 8 in Video Appendix)
The project was successful in that it demonstrated that the shape memory wire grid could be pre-circuited to selectively apply heat to a desired action. This prototype was the cornerstone for us in order to move to a more complicated system with several points of activation, which could provide a bigger variety of both visual and kinesthetic effects.

Final Experiment- 3D Selective zone heating (multi-circuited SMW grid attached to dichroic membrane)
For the final project, the nickel-titanium alloy (Nitinol) wires (.0297” d.) were again pre-set in the austenite state to be linear. Eight 1ft long wires were configured in a grid pattern and adhered to a dichroic membrane 18” wide by 18” long. The corners of the membrane were attached to a wooden frame with elastic bands. Electrically wiring was installed to provide 16 circuits to the shape memory wire grid. (See Exhibits S – U)
Specifically, the assembly was deformed to provide radiuses in the Z-axis direction. The electric circuit was powered and attached to 16 specific bents of the surface. Switches enabled the control of each point separately. The effected bends were meant to go back to their straight shape, influencing the vicinage, as it had happened to the previous experiment. (Please see Exhibit 9 in Video Appendix)
However, this project was not a complete success. The circuiting was complicated and in the cases where two or more points were activated at the same time, the voltage was divided between them reducing the power exerted to each one (connected in parallel). A series of technical problems was specified as responsible for the partial success of this prototype. Specifically, the membrane was stiff and improperly connected to the wires. Thus, it was soon not following the movement of the wires. The circuit wires, on the other hand, were very heavy and disabled the movement of the shape memory grid to which they were attached. Finally, the shape memory wires themselves should probably be stronger (have a bigger diameter) in order to support the motion of such a wide area.
In conclusion, we believe that, through the experience we gained by this prototype, the knowledge for a successful future model lies in specific modifications. These modifications include: a lighter and flexible membrane properly attached to the shape memory grid, a lighter and shorter in length circuit system, a higher voltage (or a non-parallel circuit), slightly thicker SMW for greater force.


CONCLUSIONS AND FUTURE APPLICATIONS
Being aware of the numerous complicated variables inherent in shape memory materials, we understand that our research provides only an introduction to the possibilities of these alloys. Foremost is the result that changing even a small variable can significantly influence the whole behavior of the material. A small alteration can produce a great effect. This can lead us to a variety of applications.
By focusing on the 2D and 3D concept we came up with different inspirations for future experimentation, as well as applications. In two dimensions we envisage an interactive graphic application with emphasis on the visual effect. A new cursive font could be derived from interesting “play” with shape memory wires. Specific letters could be created by the wire itself and change from one form to another by heating it in specific zones.
As far as the 3D field is concerned, future applications prove to be more abstract and vague. SMW could be used as an armature for other applications instead of being the end product. They could be seen as a means to control something over-imposed or differently related to it. A thorough analysis of the curvatures could lead to a full control of the components connected to the wires (i.e. manipulation of light reflected from the surface).
Finally, it is crucial to take into account that each material has unique properties for exploitation. The high cost, low strength or slow reaction SMW may have, worked for a long time as impediments in the use of them in the architectural environment. However, we believe it is up to the architect to study their properties more precisely and use them wisely – by accepting the differences they imply, take advantage of them and respect the smaller scale they introduce to the design by their dimensions. These materials should not be used as substitutes to replace conventional materials, but as something unique with great potential and influences even in the whole architectural thinking.

[5] For commercial exploitation, a third metal is usually added to the binary NiTi alloy to improve its properties. “Up to 30% of the nickel can be replaced by copper without loss of the shape memory effect. The effect of the copper addition is to reduce the hysteresis to about 15C and also make the transformation temperature less sensitive to changes of the nickel content.”

[11] The amount of this shape change is said to be significantly less than the obtained with one-way shape memory and very little stress can be exerted by the alloy as it tries to assume its low-temperature shape. However, the heating shape change can still exert very high forces.
