Full textLegal base regulating educational system emphasizes knowledge based on information technologies. As ICT are penetrating into the process of vocational training the training methods and aids are changing and improving, an important role is falling on an educator – teacher. He/she must develop personal communication, literary and cultural competences as well as improve information and communication skills. This may be done by applying innovative ICT training methods and only when teacher has ICT competence. The objective of this work was to elucidate the application of information communication technologies in vocational training from the management and educational aspect. To that end research instruments were formed – questionnaire, according to which the above mentioned aspects were estimated from the point of view of students and teachers, and quality research was carried out by estimating the attitude of managers. 180 students, 100 teachers and 6 headmasters participated in the study carried out in Alanta, Anykščiai and Utena institutions of vocational training in December 2006. These institutions of vocational training do have conditions for application of electronic training aids. They provide themselves with IT aids by executing project activities and inducing teachers to participate in them. The introduction of system of e-services, Internet, e-library is intended in the schools. In educational process the priority is given for traditional training aids... [to full text]
Vauché, Rémy. "Conception de générateurs d'impulsions ultra-large bande en technologie CMOS." Thesis, Aix-Marseille 1, 2011. http://www.theses.fr/2011AIX10098.
Full textThe information theory developed by Claude Shannon (1916 - 2001) highlights the fact that in order to increase the capacity of a transmission channel, it is preferable to extend the bandwidth used rather than the transmission power. This finding is the starting point of many papers on Ultra-Wideband (UWB) which led to the creation in the United States of UWB band since 2002 where no modulation is privileged. Two years later, many works on Impulsionnal Radio UWB (IR-UWB) communications began at IM2NP including the design of low noise amplifier, power detector, but also pulse generators which is the key element of IR-UWB emitters. These form basis of works presented in the manuscript that took place from 2008 to 2011. The discontinuous nature of communications impulse was first implied the introduction of new figures of merit for measuring performances of pulse generators. Then it deals with design techniques for sizing structures operating at frequencies involved, but also to reduce consumption and especially static leakage to reduce enough power consumption for embedded systems. Finally three architectures of pulse generators are developed, each one responding to different constraints in terms of frequency, consumption and range

Full textThe research work presented in this thesis is situated in the framework of wireless sensor networks (WSNs). The issue addressed is the design of a radio interface answering the specific needs of WSNs: simplicity, low cost, low power, small size, high data rate and reconfigurability. Current wireless technologies like WiFi, Bluetooth, and Zigbee are not able to respond to these requirements. Thus this study focuses on Impulse Radio Ultra-WideBand (IR-UWB) technology. At first, a joint study of the channel capacity and the hardware implementation is carried out to determine the optimal architecture of IR-UWB transceivers. This study proposes an architecture using multi-band IR-UWB (MB-UWB-IR) with a mixed implementation at 60 GHz with directional antennas. This solution is optimized according to the criteria of data rate and power consumption. To support the all the needs of WSN applications and to adapt to the evolution of the WSN’s environment, reconfigurability must be implemented in the proposed IR-UWB transceiver. This thesis presents a new solution: the reconfigurability by parameters. It supports the widest range of multi-property reconfigurability (with respect to data rate, bit error rate, radio range, power consumption, ...) of the state of the art. Finally, to validate these techniques by measurements, FPGA and ASIC implementations are realized by using the reconfigurability and the IR-UWB transceiver architecture proposed. A new method for joint synchronization and demodulation is proposed for a reconfigurable IR-UWB BPSK S-Rake receiver. The measurements show that the proposed technique improves the circuit performance: synchronization, demodulation, efficiency, network throughput, power consumption and complexity of the circuit. The proposed IR-UWB reconfigurable transceiver achieves a data rate and a wider range of reconfigurability compared to the state of the art

Full textThis Ph.D. Subject proposes the design of a new generation of wireless sensor networks (WSN) based on impulse radio ultra-wide band (IR-UWB), reconfigurable upon the application, reliable and ultra-low power. Applications like structure health monitoring of aerospace structures or portable smart sensing systems for human protection can be targeted. These industrial applications impose very demanding specifications for the wireless communication protocol (in some cases, new services are needed like: localization, clock synchronization, real-time transmission, etc) on one side, and for the circuit design, on the other side, as the ultra-low power circuits are needed. Energy efficiency is the major driver in today development of the wireless sensor networks. We chose impulse radio ultra-wideband (IR-UWB) technique for our developments. IR-UWB is a very promising technique able to respond to the wireless communication protocol constraints and to energy efficiency constraints.! The objective of this Ph.D. will be to design an ultra-low power IR-UWB transceiver. IR-UWB signal processing techniques has to be study and innovator solution has to be proposed for the implementation of the IR-UWB transceiver. The first prototype will be developed on FPGA boards (and/or USRP boards) and the final IR-UWB transceiver will be an ASIC in CMOS technology. The design of an ultra-low power consumption of the CMOS transceiver will be a major concern. Modern ultra-low power circuit techniques from the nanometrics CMOS design kits will be used. MAC layer adapted to the demands of the application and working on IR-UWB physical layer will be also studied and designed. A microprocessor integration on the chip for power management of the different parts (sensor, communication, computing, energy harvesting) of the system can also be studied. This work will be based on the previous research results obtained in our team in the case of static WSN. This work will take plac! e in the highly stimulating and competitive environment of a E! uropean project

Full textLingonberry leaves are used to increase urinary excretion, to treat urinary tract infections and for kidney and gall stones [1, 2]. The greatest impact on therapeutic effects of leaves have phenolic compounds, that inhibit the entrenchment of particular bacteria in the urinary tract, the main of them being arbutin. Recent scientific research encourages the creation of new lingonberry pharmaceutical preparations. The aqueous extracts of Lingonberry leaves (decoctions, teas) are characterised by unpleasant-bitter and astringent taste and their shelf-life is very short. Therefore, it was decided to produce lingonberry leaves syrup as a form of pharmaceutical preparation. The aim: to produce lingonberry leaves syrup and to evaluate its quality. This research includes: qualitative analyses of lingonberry leaves raw material, detection of total phenol compounds by spectrophotometric method using arbutin in decoctions of lingonberry leaves and syrups of lingonberry leaves, detection of quantity of arbutin in lingonberry decoctions and leaves by high-performance liquid chromatography, and the quality evaluation and the stability evaluation of lingonberry leaves. Results: it was found out, that the fineness of the lingonberry leaves and their loss in drying coincide with the European Pharmacopoeia herbal raw material requirements.

Main tasks: discussion of views towards information technology process and the exclusion of the view used in the work; find and examine information technology integration barriers; separate information technology integration levels; examine information technology integration according to the separated integration levels. Information technology integration is extremely dynamic and complex area, there fore it needs to be examined all the time. Due to that existing different views and analysis of the process among different specialists - most of the time process’s analysis is limited to one or few aspects or it is analyzed abstractly. Most of the time in different analysis types different views and terms occur, lack of standardization is obvious, popular view, which can’t answer all theoretical questions that come out to surface, is dominant in the area. Work‘s main propositions, which are proven in the work: two partially separated integration levels exist; different trends can be applied to them; process of substitution is the way of interaction between these two levels. Due to the high amounts of information technology, only electronic ones are analyzed in the work. This work might be useful to technological and physical scientists, management and communication specialists, students and teachers.

Full textThis work consists of 58 pages including 25th picture and 13 tables. There are 23 sources in the information sources‘ list. The work was begun 01 09 2007 and finished 19 05 2009. In the analysis of information sources the energetic plants were overlooked – their physical-mechanical characteristics, gathering and preparing for using as a fuel technologies. Also stores suitable and designed for energetic plants were overlooked. The basic biometric and physical-mechanical characteristics of willow stem chaff like frictional attributes and angle of powderiness were observed by experimental investigation. Technological parameters of chaffs‘ storage and desiccation were appointed. It was appointed while investigating that friction coefficient is lower when willow chaff is sliding through plastic surface than through metal surface. Parameters of chaffs‘ storage and desiccation were evaluated. It was appointed that chaff heats up and gets musty in the unventilated stores. 650±15 m3/(th) windblast is too weak as it also caused spoilage of chaff. It does not prevent uprise of must. It is purposeful to use 1300±20 m3/(th) and higher windblast for ventilation. The store for holding fuel resources for 800 m2 dwelling-house during three months was offered. (The store will be supported three times during the heating season).

Full textThe research on protection of traditional carpentry techniques and wooden heritage was enabled by the crisis of heritage protection in the 7th decade of XX century, when reflexive studies on heritage protection and postmodern ideas helped to disengage from modern cult of monuments. The disillusion with modern praxis of heritage protection was felt even in the practical sphere. The use of chemical materials and industrial products belied the expectancy, so the search for the means of recourse from the modern contraposition of tradition and technology was started. The notion of historical socio-cultural setting was introduced into the discourse of heritage protection, while the concept of heritage was perceived in relation to authenticity in environment, landscape and workmanship. Contemporary conception of heritage protection has already been based on the turn to traditional praxis, which ensured historical continuity. The alternative way – protection of process authenticity, which enabled creative reception of heritage, was presented. One of the main aims of the study was to examine the impulses of postmodern heritage protection, to measure its relation to modern and traditional protection of the relicts in the comparative manner. Historical reconstruction revealed that from the antiquity to the development of modern heritage protection reception of heritage was rather performed in the creative way. Historical discontinuity was conditioned by phenomenon of modernization... [to full text]

Full textCervical cancer is the second oncological disease in women in the world, and the fourth one in Lithuania. The main cause of the cervical cancer is Human papillomavirus (HPV) infection in the cervix uteri. In order to detect precancerous changes or cancer cells, a Papanicolaou (Pap) test based on cytology and HPV DNA test are used in the Western world. Currently used HPV diagnostic tests are based on molecular biology testing methods. The polymerase chain reaction (PCR) method, not the extensively used Hybrid Capture 2 (HC2) method awarded the certificate of quality by both the USA and Europe, was chosen. PCR is a particularly sensitive, fast, and commercially available method that needs a small quantity of research material and can identify the types of HPV. HC2 method does not detect HPV genotypes, false-negative results are possible because there is no internal control, and due to cross reactions, false-positive results are possible. The newest written sources state that PCR will have much potential in the future and it is thought that HPV detection standard will become 14 HR-HPV test combined with the detection of the types of HPV-16 and HPV-18. Therefore, in order to chose the optimum one for HPV tests from the commercial kits offered in Lithuania, this investigation was carried out in the National Centre of Pathology. Four different HPV diagnostic kits were used for the research. Having evaluated the research results, „Seeplex® HPV4A ACE Screening“ HPV diagnostic kit was... [to full text]

Full textThis thesis will describe the implementation of novel imaging applications with electromagnetic metamaterials. Metamaterials have proven to be host to a multitude of interesting physical phenomena and give rich insight electromagnetic theory. This thesis will explore not only the physical theory that give them their interesting electromagnetic properties, but also the many applications of metamaterials. There is a strong need for efficient, low cost imaging solutions, specifically in the longer wavelength regime. While this technology has often been at a standstill due to the lack of natural materials that can effectively operate at these wavelengths, metamaterials have revolutionized the creation of devices to fit these needs. Their scalability has allowed them to access regimes of the electromagnetic spectrum previously unobtainable with natural materials. Along with metamaterials, mathematical techniques can be utilized to make these imaging systems streamlined and effective. Chapter 1 gives a background not only to metamaterials, but also details several parts of general electromagnetic theory that are important for the understanding of metamaterial theory. Chapter 2 discusses one of the most ubiquitous types of metamaterials, the metamaterial absorber, examining not only its physical mechanism, but also its role in metamaterial devices. Chapter 3 gives a theoretical background of imaging at longer wavelengths, specifically single pixel imaging. Chapter 3 also discusses the theory of Compressive Sensing, a mathematical construct that has allowed sampling rates that can exceed the Nyquist Limit. Chapter 4 discusses work that utilizes photoexcitation of a semiconductor to modulate THz radiation. These physical methods were used to create a dynamic THz spatial light modulator and implemented in a single pixel imaging system in the THz regime. Chapter 5 examines active metamaterial modulation through depletion of carriers in a doped semiconductor via application of a bias voltage and its implementation into a similar single pixel imaging system. Additionally, novel techniques are used to access masks generally unobtainable by traditional single pixel imagers. Chapter 6 discusses a completely novel way to encode spatial masks in frequency, rather than time, to create a completely passive millimeter wave imager. Chapter 7 details the use of telecommunication techniques in a novel way to reduce image acquisition time and further streamline the THz single pixel imager. Finally, Chapter 8 will discuss some future outlooks and draw some conclusions from the work that has been done

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
