Schultz, Johan. "Sensordatafusion av IR- och radarbilder." Thesis, Linköping University, Department of Electrical Engineering, 2004. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-2193.
Full textAbstract:
Den här rapporten beskriver och utvärderar ett antal algoritmer för multisensordatafusion av radar och IR/TV-data på rådatanivå. Med rådatafusion menas att fusionen ska ske innan attribut- eller objektextrahering. Attributextrahering kan medföra att information går förlorad som skulle kunna förbättra fusionen. Om fusionen sker på rådatanivå finns mer information tillgänglig och skulle kunna leda till en förbättrad attributextrahering i ett senare steg. Två tillvägagångssätt presenteras. Den ena metoden projicerar radarbilden till IR-vyn och vice versa. Fusionen utförs sedan på de par av bilder med samma dimensioner. Den andra metoden fusionerar de två ursprungliga bilderna till en volym. Volymen spänns upp av de tre dimensionerna representerade i ursprungsbilderna. Metoden utökas också genom att utnyttja stereoseende. Resultaten visar att det kan vara givande att utnyttja stereoseende då den extra informationen underlättar fusionen samt ger en mer generell lösning på problemet.
This thesis describes and evaluates a number of algorithms for multi sensor fusion of radar and IR/TV data. The fusion is performed on raw data level, that is prior to attribute extraction. The idea is that less information will be lost compared to attribute level fusion. Two methods are presented. The first method transforms the radar image to the IR-view and vice versa. The images sharing the same dimension are then fused together. The second method fuses the original images to a three dimensional volume. Another version is also presented, where stereo vision is used. The results show that stereo vision can be used with good performance and gives a more general solution to the problem.

Neformalusis dailės ir technologinis ugdymas – aktuali tema šiandien. Neformaliojo dailės ir technologinio ugdymo galimybės aspektai nėra plačiau analizuoti. Siekiant aptarti ugdymą, kuris patenkintų mokinių ir mokytojų keliamus reikalavimus, kyla probleminis klausimas, kokios yra neformaliojo dailės ir technologinio ugdymo galimybės pradinėse klasėse?
Objektas. Neformalusis dailės ir technologinis ugdymas pradinėse klasėse.
Tikslas. Išsiaiškinti neformaliojo dailės ir technologinio ugdymo galimybes III-IV klasėse.
Tyrimo struktūra. Bakalauro darbą sudaro įvadas, du skyriai – teorinė ir praktinė dalis, išvados, rekomendacijos, literatūros sąrašas ir priedai. Darbo apimtis 46 puslapiai, tyrimo duomenys pateikti 22 paveiksluose ir 6 lentelėse.
Išvados. Mokslinės, metodinės literatūros analizė atskleidė, jog neformalusis ugdymas yra svarbus tuo, kad kompetencijų ugdymu formuoja asmenį, kuris gebėtų tapti aktyvus visuomenės narys, galintis sėkmingai joje veikti. Gerai organizuotoje veikloje vaikas turi galimybę pažinti save, savo vidinius poreikius, jaučia dvasinį pasitenkinimą. Čia vyksta sėkminga jo, kaip jauno žmogaus socializacija. Todėl bet koks neformaliojo ugdymo proceso organizavimas pirmiausia turi prasidėti nuo mokinių poreikių suvokimo.
Tinkamai organizuotas neformalusis dailės ir technologinis ugdymas kelia reikmę ugdyti vizualinę, bendrąją meninę kultūrą, formuoti estetinį skonį, harmonijos pojūtį, skatinti meninę išraišką bei kūrybiškumą.

The existing literature regarding leadership to support technology innovation in schools is limited. This qualitative study employs a multiple case study method to explore the leadership of superintendents in five school districts that have moved toward a 1:1 learning environment. This dissertation examined how superintendents gain acceptance for large-scale technology initiatives by describing the superintendent's own use of technology and their attitude about technology. The study explored the impact a superintendent's attitude and use of technology had on the acceptance of technology initiatives. The study highlights how superintendents use technology both professionally and personally. The study results indicated that while the superintendent's attitude about mobile devices in the hands of students has a profound impact on gaining acceptance for a large-scale technology initiative, it is inconclusive if the superintendent's use of technology has such an impact. The result is an important addition to the literature including recommendations for superintendents seeking to implement a large-scale technology initiative in their district

Full textAbstract:
Thesis advisor: Michael RussellThe growth of computer-based testing over the last two decades has motivated the creation of innovative item formats. It is often argued that technology-enhanced items (TEIs) provide better measurement of test-takers’ knowledge, skills, and abilities by increasing the authenticity of tasks presented to test-takers (Sireci & Zenisky, 2006). Despite the popularity of TEIs in operational assessments, there remains little psychometric research on these innovative item formats. Claims regarding their potential to provide better measurement are seldomly explored. This dissertation adds to this limited body of research by developing theory and proposing a methodology to compare TEIs to traditional item formats. This study investigated how to judge the comparative measurement value (CMV) of two drag-and-drop technology-enhanced formats (classification and rank-ordering) relative to stem-equivalent multiple-choice items. Items were administered to a sample of adults and results were calibrated using a 2-parameter logistic IRT model. Moreover, the utility of the TEIs was evaluated according to the TEI Utility Framework (Russell, 2016). Four indicators were identified as the most valuable characteristics to judge CMV and then combined into a hierarchical decision protocol. When applied, this protocol provides a CMV judgment and a recommendation of the preferred item format. Applying the protocol to the items revealed that most TEIs examined in this study showed decreased CMV, indicating that in a real-life scenario the multiple-choice format would be favored for most of these item pairs. Recommendations for the use of the CMV protocol and directions of future related research are discussed

Recently among different ways of processing of materials the combined processing is applied. Applying different complex methods of processing of a surface of materials, it is possible to reduce a roughness of a processable surface, to increase thickness of a layer of the processed surface, to increase stability to wear process and microhardness. The further prospects in processing metals are opened with use of laser radiation and ultrasonic fluctuations. It is possible to notice, that complex ways of processing of metals are still not so widely investigated. This work is intended for research of a structure of steel in the field of influence of the combined laser radiation and ultrasonic fluctuations. It is established, that applying ultrasonic fluctuations at technologies of laser processing metals, it is possible to reach more uniform distribution of impurity in a surface of metal, to level a relief of the processed surface.

Full textAbstract:
The use of Mid-infrared (mid-IR) imagers has great potential for a number of applications in gas sensing and medical diagnostics, but so far for many of those non-defence fields it has been significantly limited by their high price tag. One of the reasons behind the great cost of mid-IR imagers is that most of them need to operate at cryogenic temperatures. Thanks to more than half a century of research, state-of-the-art mid-IR photodetectors have finally achieved premium detection performance without the need for cryogenic cooling. Some of them have even demonstrated very promising results, suggesting room temperature operation is on the horizon. As a result, the cost associated with cooling equipment has been significantly suppressed. However, most mid-IR imagers are still based on hybrid technologies needing a great number of die-level process steps and being prone to connection failure during thermal cycles. The high manufacturing cost this entails is also preventing a wider diffusion of mid-IR imagers. Currently, there is still a lack of an effective monolithic approach able to achieve low-cost mass production of mid-IR imagers in the same way as monolithic integration has been widely used for imagers working at visible wavelengths. This thesis presents a novel monolithic approach for making mid-IR imagers based on co-integration of mid-IR photodetectors with GaAs-based MESFETs on the same chip. The initial focus of the project was the development of the fabrication steps for delivery of prototype devices. In order to achieve monolithic fabrication of pixel devices made in either indium antimonide (InSb) or indium arsenide antimonide (InAsSb) on a gallium arsenide (GaAs) substrate, various highly controllable etch processes, both wet and dry etch based, were established for distinct material layers. Moreover, low temperature annealed Ohmic contacts to both antimonide-based materials and GaAs were used. The processing temperatures used never exceeded 180˚C, preventing degradation of photodetector performance after fabrication of transistors, thus avoiding well-known thermal issues of InSb fabrication. Furthermore, an intermediate step based on polyimide was developed to provide a smoothing section between the lower MESFET and upper photodetector regions of the pixel device. The polyimide planarisation enabled metal interconnects between the fabricated devices regardless of the considerable etch step ( > 6 µm) created after multiple mesa etches. Detailed electrical and optical measurements demonstrated that the devices were sensitive to mid-IR radiation in the 3 to 5 µm range at room temperature, and that each pixel could be isolated from its contacts by switching off the co-integrated MESFET. Following the newly developed fabrication flow, InSb-based mid-IR imaging arrays (in two sizes, 4×4 and 8×8) are presented here for the first time, with pixel addressing achieved by monolithically integrated GaAs MESFETs. By demonstrating real-time imaging results obtained from these array devices at room temperature, implementation of a new type of monolithic focal plane array for mid-IR imaging has been confirmed. The device is suitable for further scaling (up to 64×64 pixel and beyond) and potential commercialisation. More importantly, the monolithic approach developed in this work is very flexible, as a number of III-V materials with mid-IR detecting capabilities can be grown on GaAs substrates, meaning alternative semiconductor layer structures could also be investigated in the near future.

Thesis advisor: Richard SweeneyWith climate change becoming a global problem more people are paying attention to, a common goal to reduce Greenhouse Gas (GHG) emissions is recognized by most countries. However, usually emission reduction is more difficult to achieve in developing countries because of the lack of advanced emission reduction technology. Thus,one of the important ways to improve emission reduction technology in developing countries is through technology transfer, which is to import more advanced emission reduction technology from developed countries to developing countries. In this study, I explore the level and determinants of technology transfer using data of projects from four sectors under the CDM(Clean Development Mechanism) in China. I find that large scale projects with higher emission reduction amount tend to have higher probability of technology transfer. Also, more economically and technologically advanced provinces tend to have more projects with technology transfer

Includes bibliographical references (p. 72-74).
This thesis explores the technology and market evolution of FT-IR spectroscopy over its nearly forty year history to aid in determining future product design and marketing strategies for an industry-leading firm, Bruker Optics. As a benchmark, a universal performance metric was developed that combined key specifications applicable to all FT-IR spectrometers. By researching a selected set of Bruker Optics' spectrometer systems, this performance benchmark was calculated along with each instrument's weight, volume, power consumption, and cost. The universal performance curve displayed an exponential increase from 1974 to 1988, but the rate of improvement has since decreased dramatically to incremental increase in the last twenty years. Using Design Structure Matrix analysis, the architectural trends of the same instruments were traced to discern the impact an instrument's overall design had on its performance. This analysis resulted in no definitive correlations between a spectrometer's performance and its architecture. Rather the overall instrument performance increases were attributable to individual component performance increases. However, with respect to volume, power consumption, and cost, there were clear correlations to instrument architecture. While spectrometer weight was fairly consistent over the years, decreasing instrument volume coincided with decreasing part count. Likewise, power consumption decreases over the past twenty years corresponded with decreasing energy and informational links within each instrument's architecture. The most striking correlation was the nearly perfect linear relationship between decreasing cost and decreasing instrument matter/spatial link count. Over the past fifteen years, incremental performance increase coupled with exponentially decreasing cost has resulted in FT-IR spectrometers becoming more and more commoditized. Consumers expect high performance at low cost which jeopardizes future profitability and growth for companies in the increasingly competitive FT-IR market. Bruker Optics must look to capture greater market share in segments outside of the research segment it currently dominates. By shifting from their historically product-oriented culture to a more market-oriented one, and by specifically targeting the near Infrared scanner segment, Bruker Optics will be primed for future success.

Tasks: To estimate different duck species peculiarity and analyse duck meat quality depend to market demand;
To estimate duck breeding technology and use in Lithuania farms;
To estimate risk and possibility of duck business in Lithuania.
Results. Consumer researches shows, that people prefer not fat, fragile, muscular duck meat. These features satisfy meat duck mularde females. From a technological viewpoint duck is insensitive to temperature, moisture, feed changes, so it’s possible to grow them both intensive and extensive farms.
Technological, zoohigienic and economic duck growing research showed that the most promising duck breeding is like part business – on the summer time use empty animal husbandry buildings. At best is to grow heterozic hybrids. These precondition enable in Lithuania to create small duck farms, which sells fresh meat straight from the farm and secure flexible sells and... [to full text]

Thesis advisor: John B. WilliamsonWhile much has been written about the effects of information and communication technology (ICT) on the workplace, little research has focused specifically on its effect on older workers. Using Pierre Bourdieu's theories of "capital" as a frame, I investigate how older academic faculty, clergy, and government employees have been affected by the rapid technological changes that have occurred in the workplace over the past 25 years. I conducted 75 semi-structured interviews and discovered that older workers, while generally limited in their technological familiarity and competence when compared to their younger coworkers, do have a wealth of skills that make them invaluable as employees in the modern workplace. Through the use of their social connections and organizational knowledge, I found that older workers are able to successfully mitigate almost any lack of technological skill. Moreover, as the responsibilities of workers change, because of globalization and the automation of work, I contend that the skills of older workers will be able to successfully manage the transition

Thesis advisor: Stephen J. PfohlThe Gezi Park protests, which started in May 2013 in Istanbul, rapidly turned into a movement for democracy across the country. Through in-depth interviews with protestors in Turkey, observation and content analysis, my research examines the role digital technologies played in the protests. These technologies, especially social networking tools, were used by protestors to construct personalized frameworks and forms of action. I show that this process depended on the individuals’ interpretations of their current political and cultural context, their alternative frameworks of reality. By expressing these frameworks individuals, first and foremost, challenged the politico-cultural adjustment of the society by various powerful actors. Moreover, as individuals got together in protest, alternative frameworks of reality interacted, leading to the emergence of empathy and dialogue among the protestors for long-term movement success. Digital technologies provided the necessary alternative sources for news and other information for the reconstruction of these frameworks. Moreover, they became the primary space for the production and circulation of jokes in various forms, as protestors used humor and creativity as central strategies to voice their dissent. Affective and humorous creations challenged the discipline of the political authority, hacked its presentations of reality and contributed to the formation of a carnivalesque society, where empathy and dialogue were maintained through collective effervescence

Thesis advisor: Mary TripsasThe technologies that knowledge workers use in the ongoing production of knowledge are becoming increasingly complex, embedding assumptions that previously would have been made by workers themselves. This dissertation aims to unpack this phenomena, exploring how knowledge workers encounter and use technologies in the ongoing construction of knowledge. I present three essays – one theoretical and two empirical – that examine how patterns of interactions shape technology use and consequently knowledge outcomes. In each essay, I draw on several theoretical lenses, including status, coordination, and behavioral strategy to build new theory on how and why technologies are used and understood. The first essay presents a theoretical model of how status dynamics can shape the way new technologies are interpreted and used, including whether or not knowledge workers seek to understand the assumptions in their technologies. The second essay draws on data from a two year ethnographic study of technology use within an investment bank, comparing how different groups validate the outputs of their technologies when theoretical and physical mechanisms are absent. The third essay examines the evolution of technology adoption and use within a knowledge work group, identifying the unique mechanism of departures as prompting shifts in use. This dissertation contributes to literature on knowledge work and the social construction of technology

Full textAbstract:
Thesis advisor: Lillie R. AlbertThe nation’s rapidly increasing bilingual student population has heightened the urgency behind longstanding policies and initiatives established to address systemically marginalizing education practices across academic fields, often through the use of standardized assessments. This qualitative case study explores the role of language in six fifth-grade BLs’ experiences interacting with large-scale, standardized, science, technology, and engineering (STE) open response items from a state assessment administered in English. Using student and teacher interviews, this study examines the opportunities available for BLs to display their science, technology, and engineering content knowledge when limited and specific modes of communication are validated as acceptable responses. This study draws on sociocultural theoretical research to understand the language-centered context of a state STE assessment and uses this perspective to examine the assessment as a language-based, “communicative tool” (Albert, 2000, p.2) or “communicative event” (Shaw, Geaney, & Bunch, 2010, p.914). The findings show that the assessment’s linguistic structures complicate bilingual learners’ interpretations of the open response text and ultimately reveal why these standardized measures fail to measure what bilingual learners actually know

Lietuvai tapus ES nare didelis dėmesys bei lėšos nuolatos yra skiriamos aplinkosaugai. Susidarančių problemų analizė skirstant lėšas projektams, jų statybai ir eksplotacijai, turi padėti išvengti jų ateityje. Jau prieš įstojant 2004 m. Lietuvai į Europos Sąjungą, buvo galimybė naudotis jos finasine parama, kuria Lietuva ir naudojosi. ES fondų lėšų administravimui bei veiksmingam šiomis lėšomis finansuojamų projektų įgyvendinimui užtikrinti Lietuvoje 2002 metais buvo įsteigta ISPA programos įgyvendinimo agentūra prie Aplinkos ministerijos. Šiuo metu ES lėšų iš ISPA/Sanglaudos fondų panaudojimą, projektų rengimus, pirkimus, administruoja Aplikos projektų valdymo agentūra (APVA). Vandentvarkos projektus per „kaimo infrastruktūros tobulinimo“ kryptį prižiūri Nacionalinė mokėjimo agentūra (NMA). Darbo tikslas- apžvelgti ES fondų lėšų panaudojimą nuotekų valyklų projektams ir jų įgyvendinimui, išanalizuoti nuotekų valyklose taikomas technologijas ir iškylančias statybos ir eksplotacijos problemas. Uždaviniai: Išanalizuoti senųjų nuotekų valyklų pritaikymą šiuolaikinėms technologijoms, išnagrinėti ES fondų lėšų panaudojimą nuotekų valyklų statyboms, atlikti naujose projektuose taikomų technologijų analizę.In May 2004 Lithuania became the member of the European Union; therefore now it has more opportunities for using the financial assistance provided by the European Union. New members are concerned with the utilisation of support funds of the European Union. The Ministry of Environment in 2002 established ISPA Implementing Agency that controls utilisation of EU assets from ISPA/Cohesion funds, organizes project preparation, procurements, consultations etc. In 2004 the Agency was renamed to Environmental Projects Management Agency. The National Paying Agency was established for administration of SAPARD support. Main investment targets in the field of water resource protection are: improvement of fresh water quality, reduction of surface water contamination with domestic waste, reduction of underground water pollution. Goal of work is to review the usage of EU funds for wastewater treatment projects and their implementation. This work describes the technological and regulatory changes that have occurred over the last ten years in this discipline, including: improved techniques for the characterization of wastewaters, fundamental understanding of many of the existing unit operations and processes used for wastewater treatment, especially those processes used for the biological removal of nutrients, greater implementation of several newer treatment technologies.

Thesis advisor: Jeffrey BloechlThe genetic enhancement the human genome would be humanity’s most extreme attempt in the quest for hyperagency, and will have negative implications for our sense of humanity. Hyperagency is an extreme over-expression of our own human agency; everything is transparent, subject to our control and manipulation, and in accordance with our own interests. Modern era philosophical theories in subjectivity and agency have developed, evolved, and responded to advancements in science and technology over the past few centuries, and have all contributed to the current shift in understanding of our own humanity, influencing the rise of hyperagency in the postmodern world. The act of manipulating an organism’s genetic material for the purposes of changing and modifying its characteristics is referred to as genetic modification. The term genetic enhancement is more specifically indicative of the process of modifying nonpathological, or non-disease related genes. Genetic enhancement, in the form of germline engineering especially, exhibits a dangerous attitude of hyperagency that will have negative consequences for humanity as a whole. Hyperagency not only disrupts our sense of reverence before mystery and depth but also threatens our sense of morality in relating to the world. If continued, practices in hyperagency such as genetic enhancement will lead us to lose our sense of humanity altogether

Thesis advisor: Udayan MohantyThesis advisor: Dunwei Wang
With the fast development of society, the demand for batteries has been increasing dramatically over the years. To satisfy the ever-increasing demand for high energy density, different chemistries were explored. From the first-generation lead–acid batteries to the state-of-the-art LIBs (lithium ion batteries), the energy density has been improved from 40 to over 200 Wh kg⁻¹. However, the development of LIBs has approached the upper limit. Electrode materials based on insertion chemistry generally deliver a low capacity of no more than 400 mAh/g. To break the bottleneck of current battery technologies, new chemistries are needed. Moving from the intercalation chemistry to conversion chemistry is a trend. The conversion electrode materials feature much higher capacity than the conventional intercalation-type materials, especially for the O₂ cathode and Li metal anode. The combination of these two can bring about a ten-folds of energy density increase to the current LIBs. Moreover, to satisfy the safety requirements, either using non-flammable electrolytes to reduce the safety risk of Li metal anode or switch to dendrite-free Mg anode is a good strategy toward high energy density batteries. First, to enable the conversion-type O₂ cathode, a wood-derived, free-standing porous carbon electrode was demonstrated and successfully be applied as a cathode in Li-O₂ batteries. The spontaneously formed hierarchical porous structure exhibits good performance in facilitating the mass transport and hosting the discharge products of Li₂O₂. Heteroatom (N) doping further improves the catalytic activity of the carbon cathode with lower overpotential and higher capacity. Next, to solve the irreversible Li plating/stripping and safety issues related with Li metal anode, we introduced O₂ as additives to enable Li metal anode operation in non-flammable triethyl phosphate (TEP) electrolyte. The electrochemically induced chemical reaction between O₂- derived species and TEP solvent molecules facilitated the beneficial SEI components formation and effectively suppressed the TEP decomposition. The promise of safe TEP electrolyte was also demonstrated in Li-O₂ battery and Li-LFP battery. If we think beyond Li chemistries, Mg anode with dendrite-free property can be a promising candidate to further reduce the safety concerns while remaining the high energy density advantage. Toward the end of this thesis, we developed a thin film metal–organic framework (MOF) for selective Mg²⁺ transport to solve the incompatibility issues between the anode and the cathode chemistry for Mg batteries

Full textAbstract:
Thesis advisor: Pamela J. GraceBackground: Advances in clinical care over the past 40 years have saved the lives of many infants who previously would not have survived. However, a substantial proportion of these children need on-going technological support and are cared for at home by family caregivers with or without the assistance of home care services. Existing studies describe the experience of family caregivers of technology-dependent children post-discharge, but there is a gap in knowledge related to caregivers’ perceptions of nurse-led discharge teaching. Purpose: To describe caregivers’ perceptions of nurse-led discharge education designed to prepare them to care for their technology-dependent infant in the home setting and to uncover factors that facilitate or hinder its effectiveness. Method: A qualitative descriptive study design was employed to explore caregivers’ perceptions of nurse-led discharge education efforts. Demographic data was collected prior to conducting a semi-structured interview. Interview data were analyzed in an iterative fashion using qualitative content analysis. Sample Recruitment was via purposive sampling aimed to find caregivers of technology-dependent infants under the age of three. Nine participants completed the study. Results: An overarching theme, caregiver learning and self-advocacy is enhanced by positive nurse/caregiver relationships and team cohesion, especially during anxiety-producing transitions in care, emerged from the data. The overarching theme encompasses five major themes and several major themes. The five main themes are: the nurse/caregiver relationship enhances learning; the complexity of care presents challenges to the learning process; team performance affects caregivers’ level of anxiety/uncertainty; caregivers’ level of expertise improves self-advocacy; and transitions in care settings contribute to caregiver anxiety. Conclusion: Insights that contribute to nursing knowledge of the caregivers’ experience of nurse-led discharge education and their perceptions of factors that help or hinder their learning were gained. Implications for nursing include the importance of caregivers’ involvement in care team discussions, the necessity of basing teaching approaches and materials in knowledge of best practices, and improved care coordination and discharge planning. Further nursing research, that can generalize findings and generate interventions is also needed to improve the care of this population

Lietuvos tiltų ikonografija nagrinėjama dokumentiškumo aspektu, remiantis senaisiais atvaizdais ir rašytiniais šaltiniais. Iki šiol Lietuvos tiltų istorija tyrinėta labai fragmentiškai. Tiltai - sudėtingi specifiniai inžineriniai statiniai. Visa tiltų statybos istorija byloja apie kiekvieno laikotarpio kultūrą, statybos meną, mokslo ir technikos pažangą. Šie statiniai turi istorinę, techninę, architektūrinę vertes ir yra neatsiejamas kelių plėtros atributas. Mūsų dienomis, kai kelių ir tiltų tinklas yra labai platus, tiltai tapo tarsi nepastebimi ir jų svarba šiandien iki galo nebesuvokiama. Inžinieriai visais laikais siekė statyti tvirtus, ilgaamžius ir grakščius tiltus. Dabartiniame pasaulyje vyrauja tradicija, kur tiltų architektūrai suteikiamas ypač svarbus vaidmuo. Darbe pristatomi senieji Lietuvos tiltai (XIII-XVIII a.); apžvelgiami ankstyvieji geležinkelių tiltai; aptariama tiltų statyba bei jų architektūriniai bruožai XX a.

The review is based on the materials obtained from historical archives and iconographic resources. The paper analyzes the impact of bridges on the environment and their typology, and highlights the most important bridges which are the objects of cultural heritage. The iconography of Lithuanian bridges is analyzed in terms of documentation. The study is based on the historical images and literature sources. Until the present day, the history of Lithuanian bridges has not been devoted consistent attention. Bridges are complex and exceptional engineering structures. The history of bridge construction narrates an exciting story about the culture, the art of construction, and the scientific and technological progress of the particular historical period. These structures have indisputable historical, technological and architectural value. Moreover, they are a major integral part of road construction. Nowadays, the infrastructure of roads and bridges has expanded to the extent where people no longer realize the utmost importance of bridges. The engineers of all times attempted to design strong, durable and elegant bridges. The contemporary architects tend to devote an especially great deal of attention to the design of bridges.

Thesis advisor: Marjorie HowesThis dissertation examines the dual impacts of evolutionary theory and the industrial revolution on late 19th and early 20th century transatlantic fiction, particularly in articulating the concepts of perfectibility and degeneration. Darwinian evolutionary theory made real the possibility failing to successfully evolve and adapt as a species could cause humans to go extinct or, maybe worse, devolve into monstrosities. The industrial revolution, on the other hand, enabled humans to conquer nature to a degree that suggested a power to become engineers of our own future world and selves. At the same time, this ability to understand and alter ourselves dissolved the distinction between humans and machines, and the realities of industrial technology under a capitalist system revealed that humans could also be reduced to machine-minding cogs. The two (sometimes conflated) categories of animal and machine, which we have long used to distinguish ourselves as humans, were breaking down and threatening to undo our understanding of ourselves and our place in the world. The authors whose works I discuss in this dissertation recognized that human could no longer be considered a stable category or entity, and they worked from within the received conceptual language of animals and machines to challenge our ideas about what being human means. They believed that by using imagery and narrative to re- articulate human identity and purpose, they could change behavior, morality, politics, economics, culture, and the future evolution of the species. In this dissertation, I examine the different approaches that H.G. Wells, Upton Sinclair, and D.H. Lawrence used to engage this dangerous and exciting problem of reimagining human meaning and human potential through narrative. By situating these authors in conversation with each other, I am able to highlight different facets, concerns, and shortcomings of each approach. This study also reveals that these authors were already engaging in a dynamic discussion currently gaining prominence and urgency in our own time as we explore through science, technology, philosophy, and narrative what we are and what we want to be

In the epoch of the modern global changes, a new form of society is being formed. The individual knowledge of a person is becoming a still more important basis of the quality of economic and social life. The reform of education in Lithuania is taking place for more than a decade, and within this period many essential changes occurred. Lithuania is oriented towards the aims of the European Union, it seeks to become the competitive member of the European Union, is open to various novelties and aims to strengthen its education system, so that it would educate the full-fledged members of modern society.
The present-day changes also conditioned the emergence of social problems, which had a strong effect on the whole social life, including school life. The necessity came forth to take all necessary measures for the improvement of social situation. Social pedagogues, whose position has been introduced in the educational establishments from 2001, may help to solve these problems.
One of the priority trends in the development of modern society is the rapid implementation of communication technologies in all the fields of activities. In implementing information and communication technologies at school it is also necessary to integrate in this process the functions performed by a social pedagogue.
The objective of this work is to study the opportunities of a social pedagogue, to use information and communication technologies in his activities. A social pedagogue, when performing the... [to full text]

Full textAbstract:
As the automotive industry always puts safety in focus, they want to develop systems that will facilitate the driver and in the future, eliminate the human factor. These systems require detailed tests and these tests use 3D car targets and other kinds of soft test targets. Unfortunately, there is no standard for when these test targets get too deteriorated for use. This means that there is a need to be able to measure the optical properties of these targets. This has resulted in this degree project being done. This report is the result of a project, which is done by two students at Luleå Technical University. It is done on behalf of RISE in Borås. The project is about how a 3D car target deteriorates when it is repeatedly hit. A literature study has been carried out and a portable measuring equipment has been put together and weatherproofed. When this was done, a test campaign was performed at AstaZero where a 3D car target was repeatedly hit and measurements were taken continuously. Measurement data was analyzed and it showed that the reflectance did not significantly deteriorate around the car, and that the RGB response and u'v’ values were not significantly impaired.

Thesis advisor: Richard JacksonA significant body of research has examined the impact of technology on pedagogy (Cuban, 1999; Enyedy, 2014), student achievement (Schachter, 1999; Cheung & Slavin, 2013, OECD, 2015), and equity (Reich, Murnane & Willett, 2012; Van Deursen & Van Dijk, 2011) with both positive and negative results within each domain. Research has also examined the impact of technology on the success of students with disabilities in various domains (Corn, Tagsold, & Argueta, 2012; Hargreaves & Braun, 2012; Harris & Smith, 2004; Penuel, 2006). However, no research has assessed the impact of one to one technology, in particular, on the self-efficacy of students with specific learning disabilities in educational settings. This dissertation examined the experience of nine middle school students with specific learning disabilities in the first year of a one to one laptop program. Among the guiding questions for this research was the following: What characteristics of 1:1 programs present particular challenges or opportunities for students with learning disabilities? A series of interviews with students, parents, and teachers, as well as pre and post-surveys gauging student self-efficacy, were organized within the frame of activity theory and analyzed using a case-study narrative approach. Findings from the research suggest the presence of several critical conditions that support student self-efficacy in this one to one program. These critical conditions include the presence of a culture of collaboration, putting the needs of teachers first in terms of comfort with technology, providing a system of professional development for both students and teachers, encouraging the philosophy of a growth mindset in relation to technology, and adopting a Universal Design for Learning (UDL) framework as a model for curriculum design that emphasizes equity through flexibility

Full textAbstract:
The quality of Malaysian edible bird’s nest (EBN) is still regarded inferior due to issues related to nitrite content. In August 2011, the Chinese government imposed a ban on EBN products imported from Malaysia, due to the high level of detectable nitrite (NO2-). This nitrite contamination issue has made a great impact to the edible bird’s industry whereby many EBN farmers, traders and exporters are severely affected. In 2012, the China-Malaysia negotiations agreed on the use of radio frequency identification (RFID) tags on every individual package of Malaysian EBN and set the allowable nitrite limit to be less than 30 ppm, in order to allow exportation of Malaysian EBN to China. The processing methods in EBN industry still remain crude and lack of any form of technology advancement. The purpose of this study was to investigate infrared (IR) coupled with ultraviolet C (UVC) assisted intermittent drying as a mean of EBN processing in order to preserve its nutraceutical properties, ensure nitrite content less than 30 ppm and enhance the commercial value of the dried EBN products. In the present study, EBN were dried by IR assisted drying at low temperature (25°C, 26.7% RH and intermittency =1.00), UVC assisted drying at low temperature (25°C, 26.7% RH and intermittency=1.00) and IR-UVC assisted drying (25°C-40°C, 16.5%-26.7% RH and intermittency=0.20-1.00), respectively. Both engineering properties (drying kinetics, effective moisture diffusivity and effective thermal diffusivity) and quality properties (colour, nitrite content, moisture reabsorption ability, shrinkage, sialic acid retention, antioxidant retention and storage stability) of all dried products were assessed and evaluated. The comparisons were made against samples from fan assisted drying and hot air drying. The results revealed that intermittent infrared (IR) coupled with ultraviolet C (UVC) assisted drying at temperature of 40°C (IR-UVC40) with intermittency.

Full textAbstract:
The region of the optical spectrum known as the thermal infrared (TIR) has long been a waveband of interest for space-based Earth observation. By mapping thermal variations, on-orbit TIR imaging radiometers can provide a significant amount of information regarding the temperature and emissivity profiles of the ground scene. The traditional approach to space-borne TIR instrument design usually focuses on high radiometric sensitivity and hence, typically relies on expensive and bulky cryogenically-cooled detector technology. This approach yields instruments that are very precise but are cost- and/or size-limited for flight on single large-scale satellite platforms. While these systems serve the bulk of the TIR user community needs, there are numerous user groups still ill-served due to the finite data products offered by these handful of instruments. The main objective of this thesis is to advance the field of TIR instrument design by developing a novel TIR imager, affordable and compact enough for flight on multiple microsatellite platforms, therefore enabling low-cost high temporal/medium spatial resolution TIR data products. Leveraging the latest low-cost miniaturization developments in the terrestrial uncooled TIR detector industry has been the key to reducing instrument cost and size. In this thesis, a 6 kg thermal infrared (TIR) imaging radiometer, compatible with a Surrey Satellite Technology Limited (SSTL) Disaster Monitoring Constellation (DMC) micro-satellite has been designed. The flight instrument concept utilizes two commercial-off-the-shelf (COTS) un-cooled microbolometer arrays in a pushbroom configuration to collect Earth observation data in two TIR wavebands (3-5 and 8-12 mum). After the bench-top characterisation of a prototype, a computer model was created to predict the expected on-orbit performance. Analysis has shown that a flight version of this instrument flown in the DMC would yield a 0.4 K noise equivalent temperature difference (NETD) for a 300 K ground scene, a 300-metre ground sample distance (GSD), and a 1 to 7 day ground revisit time, depending on the instrument and constellation configuration. Its application in specific niche or currently ill-served mission areas, such as autonomous global thermal change detection dedicated to highly specialized user communities, is proposed.

Full textAbstract:
Thesis advisor: Ana Martinez-AlemanCivic engagement is an activity that supports communities at local and national levels (Colby et al., 2000; Putnam, 1993; 2000). Within higher education, there has long been a desire to produce civically engaged graduates that will serve as leaders in addressing current and future societal problems. The task of developing young Americans that become socially aware, community-minded, and publicly involved requires a full understanding of the college learning environment for today's students. In recent years, the undergraduate environment has changed rapidly, with various digital social media presenting a new social and technological context for college students. Scholars have begun to explore the ways in which these social media have impacted the college environment, yet many areas for research have yet to be addressed. This exploratory qualitative study draws upon this growing literature base and social capital theory to ask: How do students understand the connection between social media use and their civic engagement while in college? This study presents data from six focus groups (n=35) and seven individual interviews conducted with students from campus organizations engaged in one of three pre-selected areas of civic engagement (Adler & Goggin, 2005). This study found that the students derived a great deal of civic value from their use of social media. These new media provide students with a constant stream of information that promotes both knowledge acquisition and the organization of others around common interests. However, findings from this study also indicate a number of challenges associated with the use of social media for civic learning and engagement, including the need to continuously filter an overwhelming amount of information and the intimidating nature of public civic debate online. The added value of social media in the development of civic behaviors speaks to a new way of thinking about ways to cultivate civic engagement. As colleges and universities continue to explore means to promote civic engagement as a learning outcome, the digital environments of students must be considered. A broad understanding of social technologies, along with a working knowledge of platform-specific features will help practitioners and scholars to better plan developmentally beneficial interventions

Full textAbstract:
Thesis advisor: Michael RussellLarge-scale assessments are often used for statewide accountability and for instructional and institutional planning. It is essential that the instruments used are valid and reliable for all test takers included in the testing population. However, these tests have often fallen short in the area of accessibility, which can impact validity for students with special needs. This dissertation examines two strategies to addressing accessibility: the use of technology to implement principles of universal design to assessment and the provision of accommodations. This study analyzed test data for students attending high schools in New Hampshire, Vermont and Rhode Island who participated in the 2009 11th grade New England Common Assessment Program (NECAP) science assessment. Three test conditions were of interest: (1) no accommodations with a paper-based form (2) accommodated test administration with a paper-based form and (3) accommodated test administration using a universally designed computer-based test delivery system with embedded accommodations and accessibility features. Results from two analyses are presented: differential item functioning (DIF) and confirmatory factor analysis (CFA). DIF was used to explore item functioning, comparing item difficulty and discrimination under accommodated and non-accommodated conditions. Similarly, CFA was used to examine the consistency of underlying factor structure as evidence that constructs measured were stable across test conditions. Results from this study offered evidence that overall item functioning and underlying factor structure was consistent across accommodated and unaccommodated conditions, regardless of whether accommodations were provided with a paper form or a universally designed computer-based test delivery system. These results support the viability of using technology-based assessments as a valid means of assessing students and offering embedded, standardized supports to address access needs

Full textAbstract:
Thesis advisor: Karen ArnoldSocial media and digital technologies are ever present in the surround of current traditionally-aged college students. Although research into understanding these experiences is increasing, there is a need for further research into what may be developmentally different for this generation. Postmodern theorists have posited that as a result of digitization, traditional conceptualizations of selfhood and identity may be changing. The contexts and affordances of these technologies are having an impact on human development and contemporary college students are uniquely situated to experience their effects. This qualitative study aimed to understand how these college students conceptualize their sense of self and identity as a result of digital and social media immersion. In particular, this study explored aspects of digital identity and digitized selfhood to surface important behaviors and developmental processes that are being impacted. Sixteen traditionally-aged college students, primarily in their fourth year of college, participated in a series of interviews and observations to probe this question and were selected as exceptional cases for their heavy usage of social technology. During this process, students were asked about how they conceived of their identity and identities online and how it impacted their overall sense of self. Findings for this study did not reveal fully realized postmodern conceptions of selfhood, such as Kenneth Gergen’s (2009) relational self, but participants did demonstrate understandings of selfhood and identity that hinted at this possibility, including what Robert Kegan (1994) would characterize as fifth order consciousness. Identities were found to be subject to contextual and relational processes that required constant maintenance and reconstruction. Additional findings uncovered college student developmental patterns that reach from being externally defined, and beholden to the views of others, towards internal definition, whereby students made conscious choices about social media use. Implications for practice include the need to educate students on digital reputation and identities, the importance of reflection and goal setting in relation to social media, and the necessity to partner with students as our collective understanding of technology evolves

Full textAbstract:
Thesis advisor: Matthew O. JacksonIn this dissertation, I focus on networks in macroeconomics and finance. In Chapter 1, I develop a theoretical model of rescue of distressed financial institutions. I study rescues in a coalition formation framework, which provides new insights into the financial contagion and stability and rescue of systemically important financial institutions. The findings show that the levels of negative shock, bankruptcy costs, interbank obligations of each financial firm and the topology of the interbank network all together determine financial firms’ contributions in rescues, where government assistance in rescues is not required in certain types of network structures. In Chapter 2, which is a joint work with Matthew O. Jackson, we study the impacts of sector level technological changes on wage inequality and GDP growth in production networks. Our results show that the macroeconomic implications of sector level technological changes depend on additional factors than the input-output structure such as type of the intermediate good (e.g., substitutes for labor vs complements to labor), task weights in production processes and labor supply. Chapter 1. I model bank rescues in a setting where banks hold each other’s financial instruments creating a network of financial linkages. Costly bankruptcies reduce interbank payments, which creates incentives for rescues by other banks. Accordingly, I analyze the sources of inefficiencies in bank rescues and show that the social welfare is maximized if regulators promote financial networks that are evenly connected (without disconnectedness/clustering) and have intermediate levels of interbank liabilities at bank level. Such networks maximize banks’ total contributions to the rescue of a distressed bank hit by a relatively small negative shock, but also ensure that banks do not fail sequentially like dominos when a bank hit by a large shock does actually fail. The results also provide a rationale for why some systemically important banks were not rescued in 2007-2008. In the model, a social welfare maximizing government assists the rescues designed to prevent the potential contagious failures and maintain financial stability instead of assisting the rescue of a bank that is hit by a large shock. Chapter 2. We study the impact of technological change on wage inequality and GDP growth in production networks. We do this in a simple model that contrasts the effects of changes in intermediate goods that substitute for labor with those that complement labor. Technological changes in intermediate goods that complement labor result in increased GDP and do not change relative wages. Technological changes in intermediate goods that substitute for (low-skilled) labor involve three phases: pre-automation, transition to automation, and post-automation. During the transition phase, technological changes in such intermediate good lead to increased wage inequality and relatively smaller increases in GDP than comparable changes in complementary goods. In addition, our results show that firm-level weights of tasks performed by different types of labor play key roles in macroeconomic network consequences of interconnectedness

Full textAbstract:
Informacinių ir komunikacinių technologijų (IKT) įtakota ugdymo technologijų raida pakeitė visų sričių, tarp jų ir matematikos ugdymo turinį. Konstruktyvistinę mokymosi paradigmą, pagrindinius šiuolaikinius didaktinius matematikos mokymo principus – suprantamumą, sąmoningą ir aktyvų žinių perėmimą, vaizdumą, mokymo diferencijavimą, individualizavimą ir kt. – gali įgyvendinti tik atitinkamos kompetencijos matematikos mokytojai. Šalies pedagogų kompiuterinio raštingumo standarto, numatančio mokytojų gebėjimus naudoti IKT ugdymo procese, vienas iš reikalavimų yra „Žinoti pagrindinių ugdymui naudojamų kompiuterinių programų tipus, gebėti analizuoti jų privalumus ir trūkumus. Mokėti pritaikyti svarbiausias bendrosios paskirties ir mokomąsias kompiuterines programas ugdymo procese“. Šio bendro reikalavimo taikymas matematikos mokymui – tai ne tik sudėtingų matematikai taikytinų technologijų žinojimo ir įvaldymo, bet ir gebėjimų tinkamai taikyti jas matematikos mokyme reikalavimas.
Informacinių technologijų (IT) ištakos yra pirmosiose skaičiavimo mašinose, kurios buvo kurtos spręsti taikomuosius matematikos uždavinius. Ir asmeninių kompiuterių (AK) pirmoji paskirtis buvo matematinių uždavinių sprendimas. Todėl matematikai skirtų šiuolaikinių technologijų yra žymiai daugiau, negu taikytinų kituose moksluose. Dar daugiau, yra programų sistemų, kuriose, atrodo, realizuota visa matematika: jos ne tik skaičiuoja, pertvarko, prastina, vaizduoja, bet ir sprendžia specifinius bene visų...

The purpose of the investigations is enhancement of the technological and educational competence of mathematics teachers. The main problems of the investigation are: characterization of the main technological tools applicable in mathematics at the university level, description which abilities, knowledge, and skills of application in teaching comprise the technological and educational ICT competence of a contemporary mathematician. Development of educational technologies, influenced by information and communication technologies (ICT), has changed the content of all spheres of education, and the content of mathematical education among them. A constructivist paradigm of learning, the main didactic principles of mathematics teaching: understanding, conscious and active acquiring of knowledge, visualization, differentiation and individualization of learning, etc., can realize only mathematics teachers of the adequate competence. The Standard of Computer Literacy of educators in Lithuania provides abilities of teachers to apply ICT in educational process. One of the requirements is “To know the main types of computer programmes useful for education, to have the ability to analyze their merits and demerits, to apply them in the educational process”. The application of the general requirement in teaching mathematics means not only the knowledge and... [to full text]

Magistro baigiamajame darbe nagrinėjama IRT įtaka smulkaus ir vidutinio verslo įmonių valdymui. IRT skverbimosi į verslą reiškinys darbe vadinamas e. integracija. E. integracija susideda iš dviejų dalių – techninės ir strateginės. Tai procesas, kuris yra nulemtas šiuolaikinių IRT santykio su įmonės valdymo metodais ir verslo idėja. Darbo pirmojoje dalyje aprašomas e. integracijos teorinis modelis, nagrinėjama mokslinė literatūra, analizuojamas teorinis informacinių bei ryšio technologijų ir valdymo metodų santykis. Antroje dalyje gilinamasi į e. integracijos ir verslo santykį per konkrečių veiklų prizmę, analizuojami e. integraciją lemiantys veiksniai. Trečioje dalyje e. integracija analizuojama Lietuvos smulkaus ir vidutinio verslo įmonių (SVVĮ) kontekste. Analizuojami empirinio Lietuvos SVVĮ tyrimo duomenys. Darbo rengimo metu buvo atliktas Lietuvos SVVĮ tyrimas, siekiant išsiaiškinti kokie veiksniai daugiausiai įtakoja įmonių techninį ir strateginį e. integracijos lygį. Apklausos duomenų statistinės tyrimo analizės rezultatai leido daryti išvadą, kad įmonių techninei e. integracijai įtakos turi įmonės tipas, o pastarajam įtakos turi strateginė e. integracija. Duomenų analizė taip pat parodė, kad strateginė e. integracija turi daugiau įtakos techninei e. integracijai nei atvirkščiai.This master’s paper presents a research on information and communication systems (ICS) influence of management of small and medium business enterprises (SME). An ICS penetration to business management phenomenon in this paper named as electronic integration (e. integration). E. integration consists of two major segments – technical and strategic. E. integration could be understood as a process, determined by the relationship of ICS and methods of business management. Lithuanian SME was examined in order to find witch factors has mainly influence for technical and strategic e. integration. Data of survey analysis shoved that: technical e. integration is affected by type of enterprise; type of enterprise is affected by strategic e. integration; strategic e. integration is affecting technical e. integration much stronger than technical e. integration is affecting strategic e. integration.
