Der volle Inhalt der QuelleThis study concerns the use of hydrophobic ceramic membranes for the concentration of the fruit juice by osmotic evaporation, as well as on the impact of the process on the endogenous flora of the juice. After having characterized the membranes and studied the impact of the cleaning on the hydrophobicity of the surface of membranes, it was possible to define a procedure of cleaning adapted to their use in food industry. The study of the performances of the process in term of evaporation flux according to the experimental conditions showed that the main resistance for the mass transfer is localized at the level of the membrane itself. Finally, even if no growth is observed in the solutions of superior concentration in 60g. 100g-1 ESS, the viability of microorganisms is not affected by the process
Ortiz, Basurto Rosa Isela. „Caractérisation de l’aguamiel et fractionnement des fructanes de jus d’agave par technologie membranaire“. Montpellier 2, 2008. http://www.theses.fr/2008MON20049.
Der volle Inhalt der QuelleThis study was conducted in order to provide new opportunities to use agaves, their cultivar being essential to the economy and the environmental preservation of Mexico. The study consists both in a general characterization of raw materials (aguamiel and agave heart's extracts) and the assessment of the potential of membrane technology in the fractionation and purification of fructans from this raw material. This study shows that the aguamiel, a juice composed mainly of sugars (67% of the dry material) and fructans (10% of the dry material) can be of interest for the production of functional drinks, not only for the presence of fructans but also because it contains free essential amino acids and -aminobutyric acid (GABA). The fructans extracted directly from agave pulquero and Agave tequilana hearts consist of a mixture of structures of the type of inulins, levans and branched graminans known as agavins. The maximal degree of polymerization (DPmax) of fructans, determined by anion-exchange high performance liquid chromatography is 80 and 25 for the Agave tequilana and pulquero respectively. A mixture of fructans obtained from the heart extracts of Agave tequilana has been subjected to a membrane separation process involving four successive filtrations optimized to extract fructans with high (>40), intermediate (10<40) and low (<10; fructo-oligosaccharides (FOS)) degrees of polymerization

Der volle Inhalt der QuelleTransformation Optics (TO) is a powerful electromagnetic design tool that enables the design of new devices such as the famous "invisibility cloak". This thesis is in direct continuation of that of M.D. Clemente Arenas (Application de la transformation d'espace à la conception d'antennes à diagramme de rayonnement contrôlé, 2014) and focuses on the use of the TO to drastically change radiation of a patch antenna. These sharp changes in radiation pattern are usually obtained using bulky superstrates made of metamaterials having exotic permeability and permittivity values. The objective of this thesis is to reduce the thickness of the superstrate and simplify the fabrication by enabling the use of standard dielectric materials. Thus, a patch antenna with realized gain of 7 dB is transformed, with the help of proposed superstrate, into an antenna having two lobes in the azimuth plane withrealized gain of 3.5 dB. The 0.12λ thick superstrate is designed using two standard dielectric materials only: Alumina (εr = 9.9) and FullCure (εr = 2.8), whereas the previous solution had variation in permittivity between 1 and 15 and in permeability between 0.3 and 3. Various degrees of freedom in the design allow adapting this solution to develop new superstrates for other applications: radiation pattern with HPBW greater than 180 ° in one plane, end-fire radiation pattern, etc. Target applications include those of aeronautics. Today, dozens of antennas on an aircraft are required to ensure the necessary communications links, identification, positioning and other purposes. The structure of the aircraft necessitates use multiple antennas to fulfill this mission, which are fixed and protrude on fuselage or wings. However, for an aircraft, these protuberances contribute to the aerodynamic drag, which results in higher fuel consumption. Therefore, the objective is to propose conformal antenna solutions with unconventional radiation pattern, which can be eventually integrated on fuselage or rudder. The concept is validated using a model made with a 3D printer and with the support of Airbus Group Innovations

Der volle Inhalt der QuelleThe aim of this dissertation is to outline essential tendencies of transformation in the new media based on the New Information Technologies (namely Internet), and to define their importance for the transfer of knowledge from science to business. In the case of tourism, it is assumed to reveal the possibilities for realization of knowledge-based tourism in Bulgaria. The methodology is oriented towards an application of the systemic approach in the field of Science studies. The main thesis is that the new media (namely Internet) permit a change of the attitudes of communicators and of the position of knowledge in the communication context in connection with their heuristic aspects. This change is affected by the new trends in science and business and it is made possible by NIT and activities of IT sector. It also reveals the perspective for knowledge-based tourism. The empirical studies (observation, deep interview, survey, analysis of web-sites) reveal the absence of preconditions in Bulgaria allowing a more perspective orientation towards tourism. The conclusions are related to the necessity of general measures and initiatives aiming to change the strategies concerning communications and tourism

Temri, Leïla. „Evolution des systèmes de production, stratégie et technologie : application au secteur de la transformation des produits de la mer“. Montpellier 1, 1994. http://www.theses.fr/1994MON10040.
Der volle Inhalt der QuelleThis thesis aims to improve the understanding of the evolution of the production systems of firms by analyzing their choices in production equipement. Specifically, the increase in automated equipement is compared to the improvement of production organization as a way for evolution. The basic assumption of the study is that the choice between these two ways depends on the spreading features of automated equipement in the industry and on the internal strategy of each firm. When applied to the case of the processed seafood industry, the study also considers as a factor the existing variation, in quality and quantity, of the supplies, due to the unstable nature of seafood and to its production mode, i. E. Fishery. In a first part the analysis points out the strategic context of the processed seafood industry, then, it shows the existence of a technological barrier, and explains it as a consequence of two factors : the specific features of seafood and of seafood and of its processing, the supply conditions of automated equipement. Eventually, a link is shown between the strategic specificities of the firms, e. G. The size and stability of supplies, and their behaviours against automation. Consequently, the behaviour of the firms depends on their stage of development. But, to explain the whole range of observed behaviours, both technological and strategic features must be jointly taken into account

Der volle Inhalt der QuelleThe recent technique of Tissue Micro Arrays “TMA” seams an essential way to investigate about the precise knowledge of tumour markers expression and their relation with the tissue architecture dynamic in the tumour development process. Briefly, this technology allows gathering, in a single block of paraffin, several hundreds of small cylindrical-shaped tissue-samples from different blocks of conventional tumour biopsies. This thesis focuses on different aspects of image processing and quality control related to TMA technology. The work is realized according to two main sections in agreement with chronological sequence of operations: design of TMA and automated analysis of TMA sections. As a first step, the concept of virtual TMA is introduced to simulate the protocols of core sampling to evaluate the TMA technology. In the second step, an original colour model associated with the chromaticity diagram xy is proposed for automatic detection of tumour markers in numerical TMA slides. The concept of sociology cell, modelled by Voronoï diagram, is finally adopted to illustrate the dynamics of the spatial distribution of cancer cells in the process of tumour development. The different methods developed in this work are applied to study the tumour markers of colorectal cancer

Der volle Inhalt der QuelleThe European Union regulation (CE n°1069/2009) imposes a step of hygienization (thermal treatment at temperature ≥ 70 °C for a treatment time ≥ 60 min without interruption) before anaerobic digestion of certain biowaste issued from the agricultural and food processing industries. This energy-consuming treatment reduces the profitability of biogas production facilities. The literature review shows that, in Europe, the energy consumption of the thermal hygienization process accounts for around 6 to 25% of the primary energy produced by biogas plants. In the present PhD thesis, the alternative solutions for the microbial pasteurization, namely the electro- technologies (e.g. pulsed electric field, PEF) were studied. These technologies are essentially developed for the athermal inactivation of pathogens in food products. The bacterial strains Enterococcus faecalis ATCC 19433 and Escherichia coli ATCC 25922 were selected as indicator bacteria. A systematical study on the inactivation kinetics of the indicator bacteria treated at different electric parameters in batch and continuous system was realized. The efficiency of the treatment coupling PEF and ohmic heating, the effect of the specific energy delivered by PEF, the recovery of the injured bacteria and the kinetic and numeric modeling of the process were investigated as well. Results confirm the ability of PEF to hygienize animal by- products (i.e. a reduction of 5 log10 of Ent. faecalis) in batch and continuous system. The PEF treatment coupled with ohmic heating could significantly reduce the energy consumption of the process

Thesis, Bordeaux, 2017. http://www.theses.fr/2017BORD0932/document.
Der volle Inhalt der QuelleInformation system tools provide support for the activities of actors in an organization. Companies replace their tools by new ones in search of performance or quality improvements, etc. However, the implementation of a new digital tool is a process of mutual adaptation between the organization and the technology, which involves changes on several dimensions and on different levels of granularity. The aim of our work is to contribute to manage these changes in order to encourage organizational innovation. We propose to grasp the diversity of evolutions in the organization and of adaptations in the tool through the diversity of ―potential‖ and ―effective‖ transformations in usages. In order to identify diversity of ―potential‖ usages, we propose to compare the diversity of ―effective‖ usages of the tool ―to replace‖ and of ―potential‖ usages of the tool ―to introduce‖. Once identified, the ―potential‖ transformations can be managed through decision making on usages to abandon, to keep, to adopt, to the emergence of new usages. It‘s the implementation of these ―effective‖ transformations that involves evolutions in the organization and adaptations of the tool. We set a usage model to consider the diversity of usages. From this model, we define methods for gradual exploration of the diversity of usages and of usage transformations, organization- and tool-oriented. We illustrate the application of methods proposed through the case study of computerization of the patient care record in a home care structure

Der volle Inhalt der QuelleResearch in the food processing has led to the development of new technologies for better preservation of the natural qualities of food. In a context of asymmetrical information, organic food processors are questioning the acceptability of these technologies. European regulations on organic production (Euroleaf) introduce principles applicable to organic processing. However, there is no precise definition or operational criteria for organic processing. A tension between the organicworld and the food processing world is emerging from this research and raises the question of possible compatibility from the consumer’s perspective. An initial qualitative study enabled us to identify consumers’ mental representations of these products and revealed the primacy ofperceived naturalness. A second experimental study examined the impact of food processing technologies on consumer reactions to organic products. Two products (apple puree and ready meal) were analysed using a full factorial design: 2 (production method: conventional versusorganic) × 3 (processing method: conduction versus ohmic versus high pressure). The results of this research confirm the positive interaction effects between organic and conventional technologies (compared with alternative technologies), although there are major disparities between product types. This thesis opens up a new field of research and invites further investigation in this topic

Der volle Inhalt der QuelleThe internet and the web are now a part of everyday life for many people. “Information and communication technologies are not a panacea, […] but they can help improve the lives of everyone on the planet”. This statement by Kofi Annan (2005, cited in ERNWACA, 2006) undoubtedly explains the ever-growing interest in Information and Communication Technologies in several areas of life. In the field of education and particularly that of distance education, many technological devices based on ICT have been implemented in recent years. This is particularly the case in Africa where these systems are supposed to provide solutions to the many challenges facing the education system in general and that of higher education in particular: massification of student numbers, insufficient teaching facilities, lack of qualified teachers and insufficient financial resources (Ndiaye, 2011, p. 19).However, the introduction of a technological device in the educational field is not always an easy task (Missonier, 2008). There are many constraints, especially in Guinea where the context is marked by enormous infrastructural, equipment and training deficits for stakeholders in the use of ICTs. Based on network actor theory (ANT), our study seeks to understand how local specificities participate in the construction of a socio-technical device for distance education. The latter is likely to modify the way in which actors communicate and inform themselves, as well as their teaching and learning practices. This thesis analyzes the process of deploying a socio-technical device for distance education at the Higher Institute for Distance Education - ISFAD (Republic of Guinea). It aims to understand the implication of local specificities in the technology deployment process, as well as in the implementation of the operationalization of the technological device

Der volle Inhalt der QuelleThe constant and rapid evolution of digital technologies creates challenges for organizations. They are adapting to a changing, complex environment requiring new digital approaches. Higher education are not immune to these challenges, whether the impetus for a transition is ministerial, institutional or, more recently, governmental. Nevertheless, although teaching in French universities is legally based on missions, it has above all a particular social practice and is based on a fundamental principle of academic freedom. The activity is complex, relational, dynamic and discretionary. This work deals with the influence of digital technologies on employees in the transformation of the activity and focuses more specifically on the case of the use of virtual reality in French higher education. We explore this issue at the crossroads of two visions of the digital transformation of work, individual learning and behavioural determinants, by mobilising activity theory and its fields of practice. We also position this research in the pre-implementation phase of a virtual reality technology, thus taking an interest in an anticipatory use, a prospective activity. A literature review and a first exploratory empirical phase composed of a qualitative study by semi-directive interviews and a mixed study by Q Method (36 complementary observations), define a structural model of the influence of the prospective digital transformation of activity on teachers. A second confirmatory phase tests this model via a quantitative study by questionnaire survey. A collection of observations from 314 tenured teacher-researchers in management sciences in 31 French universities is analysed. The studies as a whole made it possible to define six trajectories of transformation of teaching activity, according to three profiles of a daily activity and two profiles of a prospective activity induced by the use of virtual reality in teaching. Our results show that these trajectories of transformation exert a significant and ambivalent influence on teachers, an ambivalence that is mainly based on the perception of daily activity. As soon as this activity is centred on the learner, the influence is positive; when it is centred on the symbolism of the teaching subject or on the instrument of the activity, the influence is negative. The weight of an empowering environment in relationships is also shown to be composed of a balance to be achieved between autonomy and support: a necessary accompanied autonomy that would allow a digital transition while respecting academic freedom. Finally, in the use of virtual reality, the student-teacher relationship is part of a renewed learning framework. Our proposal to reflect on a paradigm shift is supported: the simulated environment creates both distance and rapprochement, it distances in the learning space but brings together in the creation of meaning and the co-construction of this new space. In the light of teachers' expertise, the digital transformation of teaching activity could not be divorced from the central actor that is the teacher, because technological capacities would not supplant them, on the contrary, they would be a real tool for renewed cooperation where activity would not evolve through digital technology but accompanied by it. Thus, although it has its limits, this research provides a new brick of understanding by underlining that anchoring an actor in his activity is meaningful and that understanding activity profiles is an interesting lever to use in order to understand the challenges and stakes involved in a digital transition

Der volle Inhalt der QuelleThis research attempts to build an intelligibility of knowledge empowerment in the newconfiguration of a web class. It crosses the web-user’s expecting and what is really “going on” in an approach "applied associationist" at the heart of the class while a pilot-teacher evolved a device to enable it to overcome its own professional dilemmas. It took place during the academic year 2009-2013. The analysis was used to validate the research hypotheses and to identify ways to implement dynamic learning benefits. It retools with 1) a systemic analysis of teaching relationship while it is extended to actors of a new type, the web applies: 2) a systems approach to mental activity of students reveals vicarious interactional phenomena in the teaching / learning, 3) a consideration of field observations and requests for players to change how observation of classroom interactions as the technological tools to optimize the phenomena of self-learning. This study confirms the common assumption that web-classes permit an attractive learning activity. Field study shows that teachers reach with web-classes an ethical stance of authority affilated to pedagocical spirit. Flichy talks about « an authentical speech adress to another person», « words of seeking and not strong and savant words to person » (FLICHY, 1995 pp.77, 82). Classroom turns on a landmark in that self-directed learning is authorized and mind are prepared to led them to the most arbitrary and fortunate of encounters. Social networks on the Internet allow teachers to cooperate and share their own teaching material and pedagogical methods. It should contribute to the emergence of an open design teaching thrown to the wind
Delannoy, Stéphanie. „Développement d’alliages de titane innovants à gradient de propriétés pour applications implantaires“. Thesis, Paris 6, 2017. http://www.theses.fr/2017PA066653.
Der volle Inhalt der QuelleThe work carried out concerns the development titanium alloys with elastic gradient. They are part of the development of materials dedicated to dental implantology, in collaboration with the company Biotech Dental. The elastic discontinuity observed at the bone / implant interface has been called into question in the occurrence of bone resorption phenomena which can lead to implant failures. The lowering of the surface modulus could then allow a more appropriate transfer of stresses which would lead to an improvement of the osseointegration. An upstream work, based on the consideration of electronic parameters and biocompatibility elements, made it possible to select alloys which can exhibit a great elastic variability: Ti-13Nb-13Zr (wt.%) and Ti-20Nb-6Zr (at.%). A preliminary study carried out on laminated samples allowed to confirm this variability and to associate the elastic bounds obtained with different microstructural states. On the basis of these observations, we have developed approaches combining sequences of deformation and short heat treatments on massive samples. Thus, on the TNZ, a surface deformation approach by shot peening applied on a β-quenched state made it possible to obtain a gradient of 65 GPa to 85 GPa over 400 μm. And a preferential dissolution approach on the Ti-13-13 has lead to a gradient of 75 GPa to 130 GPa on 100 μm, via the realization of flash thermal treatments on massive samples in the precipitated state previously shot-peened. These results have thus validated the previously designed material - strategy - process combinations. They also allowed a rationalization of the different possible approaches to obtain the elasticity gradient

Der volle Inhalt der QuelleThe transformative capabilities of technologies have great potential contributing to change that benefits society, the environment and human well-being. The world faces many grand challenges today, such as climate change and extensive digital change. Investors affect which technologies shaping our societies and organizations that are mission-driven, rather than entirely profit-driven, can affect the paradigm shifts that are to come. Despite an increased interest in the field of “transformative technologies”, there is a lack of consensus on basic characteristics and what the term entails. The lack of defining characteristics results in a risk of the term being diluted, which further has negative effects linked to decision-makers’ lack of approaches to evaluate transformative abilities in technologies. Decision-makers can be helped by a more defined concept, and through applicable methods, decision-makers can be helped to achieve their goals. Existing methods for evaluation of so-called “responsible investments” such as ESG and Impact investing are not focused on transformative capabilities of technologies. Furthermore, some limitations make them less applicable in cases where transformative technologies are relevant. The study contributes to an increased understanding of the concept and provides methods for evaluation by analyzing transformative capacities in Industrifonden's portfolio companies in the field of transformative technology. The empirical basis consists of 12 portfolio companies. The study highlights three dimensions of characteristics for transformative technologies, value changes, mimicry and diffusion, and contributes to an understanding of their meaning. Furthermore, the study shows recurring patterns in terms of transformative characteristics. In addition to the contribution linked to an increased understanding in the area, the study provides suggestions on how these technologies can be evaluated and how evaluation methods can be applied to investment strategies.

Además, describo el principio de funcionamiento de las DEFCs y el EOR electrocatalítico. También se explican las estrategias para sintetizar nanocristales de alto rendimiento para aplicaciones de almacenamiento y conversión de energía electroquímica. Finalmente, en este capítulo discuto el fenómeno de la evolución estructural y química de los nanocristales durante las operaciones electroquímicas y cómo se necesita su caracterización en cada sistema para una comprensión profunda de las propiedades y aplicaciones de los nanomateriales. El capítulo 1 también incluye los objetivos de la tesis. El Capítulo 2 describe un método de crecimiento simple mediado por semillas a baja temperatura para crecer Mn3O4 en nanoparticulas huecas de Fe3O4. Se lleva a cabo un proceso de sinterizado a temperatura moderada (500 °C) para promover la reacción en estado sólido de las NPs y obtener partículas huecas de MnxFe3-xO4. Al ser usados como materiales de electrodo anódico, la cubierta policristalina, el espacio vacío interno y la gran área de superficie de las NPs de MnxFe3-xO4 pueden amortiguar de manera efectiva el cambio de volumen de los nanocristales durante el proceso de litiación y delitizacion para mejorar la estabilidad y la vida útil del ciclo. Se evalúa la actividad electroquímica de las NPs de MnxFe3- xO4 hacia la reacción de litio y se explora la relación entre la estructura y las propiedades electroquímicas. El excelente rendimiento de las NPs huecas de MnxFe3-xO4 está asociado con su estructura y composición cristalinas, y con la presencia de ligandos carbonizados, que promueven aún más la conductividad eléctrica y acomodan y liberan rápidamente iones de litio mientras retienen una estructura estable incluso después de ciclos continuos de carga/descarga . Este trabajo fue publicado en Nano Energy en 2019. El Capítulo 3 vesra sobre el rendimiento de los NPs bimetálicos como ánodos en LIBs y KIBs. NPs monodispersas de CoSn y NiSn se sintetizan mediante co-reducción y se soportan en materiales comerciales de carbono. Los nanocompuestos obtenidos se prueban como materiales anódicos en LIBs de media celda y KIBs y LIBs de celda completa. Los electrodos CoSn@C muestran excelentes capacidades de carga y descarga en media celda y celdas completas LIB. Las capacidades para KIB se estabilizan alrededor de 200 mAh g-1 con alta eficiencia culombiana durante 400 ciclos para CoSn@C y 100 mAh g-1 para NiSn@C durante 300 ciclos. La oxidación de las NPs, la formación de la capa SEI, el vasto cambio de volumen durante la litiación y la delitiación causaron la disminución de las capacidades. Este trabajo fue publicado en ACS Applied Materials & Interfaces en 2020. En el capítulo 4, se detalla un enfoque simple para producir nanocubos intermetálicas de Pd3Pb con geometría cúbica bien definida y un tamaño promedio de 6 nm a 10 nm. Los catalizadores de Pd3Pb/C presentan actividades y estabilidades electrocatalíticas EOR mejoradas. La actividad EOR de las NPs de Pd3Pb se investiga en función de su tamaño a través de técnicas CV y CA. Todos los catalizadores exhiben una disminución de corriente pronunciada durante los primeros 500 s de operación EOR continua, que está asociada con la acumulación de intermedios de reacción fuertemente adsorbidos y el bloqueo relacionado de los sitios de reacción. Los catalizadores pueden reactivarse simplemente ciclando para eliminar eficazmente las especies adsorbidas en la superficie y recuperar la actividad electrocatalítica. Una reorganización de los elementos Pd y Pb ocurre en las NPs de Pd3Pb durante EOR, lo que implica una difusión hacia afuera/hacia adentro de Pd/Pb para equilibrar la estequiometría de la superficie de los NCs, que es impulsada por la diferente afinidad de Pb y Pd hacia el oxígeno y posiblemente el etanol, y la oxidación/reducción electroquímica de Pd. Este trabajo fue publicado en Chemistry of Materials en 2020. El Capítulo 5 demuestra la síntesis de NRs coloidales de Pd2Sn que incorporan P a través de la fosforización de las NPs de Pd2Sn con un reactivo altamente activo. El catalizador Pd2Sn:P/C exhibe una actividad significativamente mejorada hacia EOR en medios alcalinos en comparación con Pd2Sn/C, PdP2/C y catalizadores comerciales de Pd/C. La mejora del rendimiento se racionaliza con la ayuda de los cálculos de DFT teniendo en cuenta los diferentes entornos químicos de fósforo. Dependiendo de su estado de oxidación, el fósforo superficial introduce sitios con adsorción de OH de baja energía y/o influye fuertemente en la estructura electrónica del paladio y el estaño para facilitar la oxidación del acetilo al ácido acético, que se considera el paso limitante de la tasa de EOR. El Pd2Sn:P se caracteriza por una superficie rica en Sn y P, que se correlaciona bien con los porcentajes más altos de estaño oxidado y fósforo, y la mayor tendencia a la oxidación de Sn en comparación con Pd. Los cálculos de DFT demuestran que la presencia de P puede inducir una mayor adsorción química de OH- para facilitar la formación de CH3COOH, lo que resulta en un aumento de la actividad EOR. Este trabajo fue aceptado en Nano Energy en 2020.

As with utopian promises, where technology contributes to the convenience and welfare of human society, technology also has the contradictory consequences of enforcing humans to conform to a biased politics often without negotiation. How do I, as an individual, challenge such unwanted enforcement? Can I meet this challenge without producing yet another coercive technology? In this thesis, I argue that technologies for transforming the self can function as emancipatory strategies against such coercive technologies, without reproducing them. My hypothesis is that these technologies for transforming the self can be achieved through strategizing and experimenting with the self. This strategizing and experimentation involve identifying and exploring the following conditions: standing on the border of both sides of ambivalence in the self-technology relationship, taking the risk of failure in this position, and expanding these conditions to multiple selves. The repetition of strategizing and experimenting with the self can generate constant self-transformations. To test/experiment this hypothesis, I design and activate performative situations for self-transformative experiences of an individual, and a group. In these situations, objects act as catalysts and structures for action and dialogue, while revealing the ambivalence in them-as technologies of coercion and freedom.

New information technologies can greatly impact the landscape of business and even entire industries. For some, these changes are both welcome and anticipated. For others, technology seems to cause more problems than it solves. The ability to interrelate technology and business strategy is what differentiates these two groups. Strategy, not technology, should guide the direction of the business. This thesis presents a simple set of current business frameworks for analyzing the business transformation effects of new information technologies. The analysis includes the five force method, value chain analysis, and Gary Hamel's business model. Both the five force method and the value chain analysis are from the work of Michael Porter. Next, the thesis introduces a case drawn from the Department of Public Works (DPW) in Arlington, Massachusetts. Currently, the water department in the DPW plans to install a new wireless data collection system and a new data analysis application. The new technologies allow the DPW to collect and analyze customer's meter readings more efficiently. Through the use of the above mentioned business analysis tools, this thesis explores the possible business transformation effects caused by the implementation of the new technologies. By examining the future effects, the town can make a more educated decision regarding when and how to implement the new IT systems. Also, the analysis may help to eliminate unexpected issues before they arise both during and after the implementation.

The Internet is currently keeping managers awake at night. Surveys conducted in various industries and regions around the globe typically show that more than 90% of the executives consider that the Internet will transform or will have a major impact on the global market place. This work addresses this problem. It focuses on the issues of business transformation that result from the widespread adoption of the Internet, by manufacturers, distributors and consumers. In almost every industry, the Internet is bringing important business changes. The developments are bringing new competitors to the market place, bringing new forms of competition, and are reshaping industries. Two of the key issues to address are the identification of the major industry changes and the identification of the core capabilities required for implementing successful Internet ventures. Among established industries, financial services are already being strongly impacted. Financial services' products and financial services' value chain are predominantly built on information and its products underlay many of the other industries' activities. Bill payment and retail stock trading are leading the categories with higher share of online execution. The use of the Internet in the financial services industry is specifically analyzed in this work.

Der volle Inhalt der QuelleWhen solids are subjected to tribologicalloads, strilctural changes can occur both at the surface and in depth, immediately below the loaded area: in the case of sorne materials, especially metals, these changes are known as solid/solid phase transformations or Tribological Surface Transformations (TSTs). Ferrite/martensite phase transformations ofthis kind, resulting in the formation ofwhite layers, have been occurring during the last few years in sorne types of French train rails, mainly at the surface of straight sections of the rails. Ln order to account for the formation ofthese TSTs, a thermo-mechanical model is developed here in the framework of the Thermodynamics of Irreversible Processes, where the modelling procedures used are based simply on defining a thermodynamically and physically admissible state potential (in the case of the reversible aspects) and threshold area (in that of the reversible aspects). 8ased on this formulation, two thermodynamically consistent others models are developed, using the results of previous studies in the field of TRansformation Induced Plasticity (TRIP). The numerical integration of the constitutive equations involved in these three models was performed using Retum Mapping Algorithm methods in the Aster finite element code developed at the company EDF. The numerical results presented as examples show these three models ability to describe solid/solid phase transformations ofthis kind

Der volle Inhalt der QuelleExecutives and directors are seeking to transform their enterprises into more efficient operations to achieve a competitive advantage and increase shareholder value. In addition, modern enterprises are deploying new technologies to attain the desired efficiencies inherently promised by technology advancements. However, the transformation and technology adoption results vary considerably between failure and success. Therefore, to identify an efficient and consistent method for guiding transformation efforts, we conducted a literature review of the technology adoption models, enterprise transformations, systems of systems, and human factors to identify efforts directed at integrating these research areas. This holistic approach guided the research method in which we subsequently conducted a qualitative action research case study to identify the influencers of technology adoption factors. The results of the case study identified the factors of human perception (salience, effort, expectancy, and value) are key influencers that accelerate technology adoption during the deployment phase similar to the application of human factors during the development phase of the technology lifecycle. These influencers generate perceived value for the technology and tools employed during enterprise transformations. Furthermore, we propose a model for using technological capabilities to enhance enterprise transformations based on context, process-based work instructions, work-instruction-based training, and subject-matter-expert desk-side support. Consequently, we determined that this perceived value technology adoption model should be a preferred tool for new technology deployments in addition to updating existing deployed technology for increased value that can be leveraged for lasting enterprise transformations.

Der volle Inhalt der QuelleIt appears that the critical mass stage for integrating ICT into teaching and learning has been reached by the teaching staff involved in the Curtin survey sample. The most common teaching mode adopted by the survey sample is the traditional lecture and tutorial (workshop or laboratory) mode. However, the data revealed that over the 16 month period of the study there was a large increase in the use of Web-based material for teaching and learning. The data revealed that a number of factors emerged which affected the adoption of ICT. These factors included: leadership across the university, attitude toward the use of ICT; the perceived benefits of adopting ICT in teaching and learning; incentives, modeling mechanisms, the provision of adequate support structures; the time factor; training; facilities and resources. The reflective monitoring system utilised in this study (the TracIT reports) revealed the changes in ICT behaviour and the changes in the ICT environment, as well as the source of initiation of the change. It appears that most of the 'real changes' which occurred in the teaching practice of the case study sample were individually driven, with some others being influenced by their own Department/School or by student pressure. The study also found that the adoption of ICT into the working environment of a university teacher significantly increases the workload of individual staff. The existence of transformational leadership across all levels of the University was identified as a major factor in the promotion and adoption of ICT and ultimately the development of a truly professional learning community.
From the extensive data collected in this longitudinal study an empirical model or framework, the "Curtin University Professional Learning Community Model", was introduced. Many of the teaching staff at Curtin University involved in this particular study have clearly demonstrated their commitment to the adoption of ICT for teaching and learning. The detailed case study data has also revealed that many of the teaching staff possess professional attributes which would be admired and valued in any university. Universities are facing the challenge of identifying what role ICT will play in the future of higher education and how to implement the appropriate strategies which will meet these needs. This study has found that the key to meeting the challenge seems to be to harness strategies that lead to the development of a professional learning community. The Curtin University Professional Learning Community Model has identified the key elements which need to be in place if the use of ICT for teaching and learning is to be not only adopted, but sustained and more importantly, effective in the teaching and learning process. This study has clearly revealed that it is only through the synergy of university commitment and individual commitment that real change can actually take place, the change in this case being the adoption of ICT in teaching and learning practices. The strategies suggested by the empirically derived model can begin this journey to a truly professional learning community.

Der volle Inhalt der QuelleBody and territory share a common and singular condition; that of becoming suspended between persistance of the past and solicitations from a present-future radically overrun by new technologies. In the present day and age the level of complexity and variation reached by the processes of transformation, engaged above all by new technologies, call for a change in paradigm. Altogether analogously to the government of bodies, the government of territory must also be explored like an environment, a plural and complex tissue crossed by relations that are infinite and changing. This is why the aim of the present project is to deal with only some of the crisis zones. The first chapter essentially refers to the metamorphosis of the urban in relation to the cybernetic revolution and to the new hierarchies engendered by the ongoing contradictory process of dematerialisation. The second chapter is mainly devoted to analysing the mythologeme of technique and the way it tends to modify the styles and practices of everyday life. The third chapter circumscribes analysis to what has been currently defined as new metropolitan fears which set the plan for existence and life in terms of the space of risk. Such risk determines a whole series of considerations connected with it: security systems, systems of assurance, organisation of new control devices. The last chapter brings these various issues together interpreting them in the light of the opposition between geophilosophy and geopolitics, between “other spaces” and the spaces of total control and homologation. To understand territory in its bodily expression enables one to identify central nodes that cannot abstract from the processes of subjectivazation forming the geography of territory and not just a catalogue
