Creating for the first time GUI (graphical user interface) applications is an endeavor that can be most challenging. This article introduces the general concepts of GUIs and the need to interact with GUI elements only on the so called "GUI thread". The concepts pertain to GUI applications written for Windows, Linux and MacOS alike. Using Java libraries for creating Rexx GUI applications makes these Rexx GUI applications totally platform independent. Taking advantage of BSF4ooRexx even the powerful JavaFX GUI libraries can be exploited by pure Rexx, allowing Rexx programmers to create the most demanding and complex GUI applications in an unparalleled easiness in an astonishing short period of time. The introduced GUI concepts will be demonstrated with short nutshell examples exploiting the JavaFX GUI libraries, empowering the Rexx programmers with the ability to create stable and error free GUI applications in Rexx.

No. of bitstreams: 1 Katia Cristina Luz.pdf: 1165048 bytes, checksum: 6e68c98744efd44f8eb30c6f9c8600f3 (MD5) Previous issue date: 2016-09-20 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / The objective of this research is to analyze the academic production on autism, through trend of scientific production balance in Brazil contained in the Portal of journals available through the coordination of improvement of higher education (CAPES), Ministry of education, for every period of coverage of the portal, that is, the 1983 2015, based on the contributions of cultural materialism (WILLIAMS, 1980), especially with regard to the narrative and analysis of the concept of scientific field (BOURDIEU, 1983). The choice of the three factors: 1) because they are considered the most advanced scientific communication vehicles (journals) and that, in principle, must meet state-of-the-art production on the subject; 2) not to restrict the national publications, but cover a wider range of international publications; 3) for being one of the most widely used databases by the academic environment expressed the availability of official publications to be used by researchers, teachers and students. Seeking to ensure the quality of articles (initially, the survey, by means of the descriptor "Autism" resulted in 657 productions), it was decided to restrict the selection to only peer-reviewed journals, which, after exclusion of that repeated themselves and those who did not have summaries, once the preliminary reading would break them, resulted in 113 productions were the corpus of the balance sheet of the first part of the research trend certain items were selected on which made more refined analysis, based on reading the full text. The main findings show that there is a symbolic struggle between medicine and psychology with regard to etiology and characterization of autism, the gradual incorporation of traditional classificatory system of Psychiatry (DSM), effected by the general medical classification (CID), which resulted in the adoption of the term "autism spectrum disorder" which appears to have expanded too much criteria for its determination / O objetivo desta pesquisa é a análise da produção acadêmica acerca do autismo, centrado em balanço tendencial da produção científica no Brasil, contida especificamente no Portal de Periódicos, disponibilizado pela Coordenação de Aperfeiçoamento do Ensino Superior (CAPES), do Ministério da Educação, durante o período de vigência do portal (1983 a 2015). Tem-se como base teórica as contribuições do materialismo cultural (WILLIAMS, 1980), especialmente no que se refere à análise de narrativas e do conceito de campo científico (BOURDIEU, 1983). A escolha de periódicos contidos nesse portal se deu em virtude de três fatores: 1) serem considerados os veículos de comunicação científica mais avançados (periódicos) e que, em princípio, devem reunir a produção de ponta sobre o tema; 2) não se restringirem a publicações nacionais, mas abrangerem uma gama mais ampla de publicações internacionais; 3) ser um dos bancos de dados mais utilizados pelo meio acadêmico, expressando assim a disponibilidade oficial de publicações a serem utilizadas por pesquisadores, professores e estudantes. Em busca da garantia da qualidade dos artigos (inicialmente, o levantamento, por meio do descritor ―autismo‖, redundou em 657 produções), decidiu-se restringir a seleção somente aos periódicos revisados por pares, os quais, após exclusão dos que se repetiam e os que não possuíam resumos, uma vez que a sua leitura preliminar partiria deles, resultou em 113 produções que constituíram o corpus do balanço tendencial da primeira parte da investigação. A partir dessa etapa, foram selecionados determinados artigos sobre os quais se efetuou análise mais refinada, com base na leitura do texto integral. Os principais achados evidenciam que ocorre uma luta simbólica entre a medicina e a psicologia no que se refere à etiologia e caracterização do autismo, uma vez que a incorporação gradativa de sistema classificatório tradicional da psiquiatria (DSM), de classificação efetuada pela medicina geral (CID) redundou na adoção do termo ―transtorno do espectro do autismo‖, o que parece ter ampliado em demasia os critérios para a determinação do que venha ser autismo

Many reports, scientific papers, patents, and scientific news investigate the feasibility and affordability of direct carbon dioxide capture from the atmospheric air (DAC). Since carbon dioxide (CO2) is extremely diluted in the atmosphere, large volumes of air have to be handled to capture comparable amounts of CO2. Therefore, both the energy consumption and the plant size are expected to be 'prohibitive'. On the other hand, some analyses have shown that DAC is feasible and can become affordable with essential research and development. DAC has been regarded as an optional bridging or a transitional technology for mitigating CO2 emissions in the medium-term. Priorities include investing in renewable and low-carbon technologies, efficiency and integration of energy systems, and realisation of additional environmental benefits. A heavy reliance on negative emission technologies (NETs), and consequently DAC, may be extremely risky as NETs interact with a number of societal challenges, i.e. food, land, water and energy security. Although, "... capturing carbon from thin air may turn out to be our last line of defence, if climate change is as bad as the climate scientists say, and if humanity fails to take the cheaper and more sensible option that may still be available today" MacKay (2009). Certainly, more research is necessary to bring down both cost and energy requirements for DAC. This work firstly predicts the adsorption equilibrium behaviour of a novel temperature swing adsorption process, which captures carbon dioxide directly from the air, concentrates, and purifies it at levels compatible to geological storage. The process consists of an adsorption air contactor, a compression and purification train, which is a series of packed beds reduced in size and connected in-line for the compression and purification purposes, and a final storage bed. The in-line beds undergo subsequent adsorption and desorption states. The final desorbed stream is stored in a storage bed. This cyclic process is repeated for a number of times imposed by the required purity and pressure in the final bed. The process is been thermodynamically verified and optimised. Since, the overall performance of this process does not only depend on the design of the process cycle and operating conditions but also on the chosen adsorbent material, further optimisation of the adsorptive and physical properties of the solid adsorbent is investigated. Thus, the optimal parameters of the potentially used porous materials is identified. Continuing the research on different adsorbent materials, an experimental investigation on the equilibrium properties of two competitive adsorbents is also performed. Besides the thermodynamic analysis, a dynamic model is presented for the investigation of the mass and heat transfer and its influence on the adsorption rate and consequently on the overall process performance. Since the initial stream is very dilute, it is expected that the adsorption rate will be low compared to other temperature swing processes and the capture rate will be affected by the heat transfer. Finally, the design and development of an experimental laboratory-scale apparatus is presented and analysed. Future design improvements are also discussed.

Mulheres submetidas à mastectomia, apresentam assimetrias posturais, assim como alterações na cinemática do movimento do ombro e tronco. O objetivo deste estudo foi avaliar o equilíbrio estático bem como a marcha em mulheres submetidas à cirurgia de mastectomia unilateral. Para tanto, foram analisadas 42 mulheres, divididas em dois grupos: mulheres submetidas à mastectomia unilateral (GM), com idade média de 53,77±7,24 anos, e mulheres sem a doença como controle (GC), com idade média de 54,70±6,31 anos. As análises do equilíbrio estático e da marcha foram efetuadas com sistema Vicon System (VICON-MX-T40S, Oxford, Inglaterra). Foi avaliado o equilíbrio estático com olhos abertos e olhos fechados, com e sem o uso da prótese mamária externa, por meio da área e do deslocamento do centro de massa projetado no chão, assim como o ângulo da coluna. Na marcha, foram avaliados os parâmetros espaço-temporal com e sem o uso da prótese mamária externa, e a oscilação dos membros superiores e do tronco. Foi aplicado o teste de normalidade de Shapiro-Wilk, diante de uma distribuição normal e relacionada, aplicou-se o teste T relacionado, e para amostras independentes, teste T independente, em distribuição não paramétrica, foi aplicado Wilcoxon para variáveis relacionadas e Mann-Whitney, para variáveis independentes. Foi fixado o nível crítico de 5% (p<0,05), o processamento dos dados efetuado pelo software SPSS, versão 17.0. A análise do equilíbrio estático apontou aumento significativo na área e no deslocamento do centro de massa projetado no chão, e deslocamento médio-lateral do ângulo da coluna. Na marcha, houve piora dos parâmetros espaço-temporal e menor oscilção do membro superior homolateral à cirurgia para movimentos de flexão/extensão e abdução/adução, o tronco apresentou menor oscilação médio-lateral. A prótese parece não ter influenciado no equilíbrio e na marcha. Os resultados sugerem que a mastectomia unilateral pode afetar o equilíbrio e a marcha. / Women undergoing mastectomy, have postural asymmetries as well as changes in the kinematics of the movement of the shoulder and spine. The objective of this study was to evaluate static balance and gait in women undergoing unilateral mastectomy surgery. Therefore, 42 women were analyzed, divided into two groups: women who underwent unilateral mastectomy (GM) with a mean age of 53.77 ± 7.24 years, and women without the disease as control (GC) with a mean age of 54.70 ± 6.31 years. Analyses of static equilibrium and gait was performed with Vicon System (MX-T40S-VICON, Oxford, England). We evaluated the static balance with eyes open and eyes closed, with and without the use of external breast prosthesis through the area and the center of mass displacement designed on the floor, as well as the angle of the spine. On the gait were evaluated spatiotemporal parameters with and without the use of external breast prosthesis and the oscillation of the upper limbs and trunk during walking. The functionality of the upper limbs was measured by the DASH questionnaire, and the level of physical activity by IPAQ. We used the Shapiro-Wilk normality test, before a normal and related distribution, we applied the related t test for independent samples and, independent t test, in non-parametric distribution, Wilcoxon was applied to related variables and Mann Whitney test for independent variables was set the critical level of 5% (p <0.05), the processing of data carried out by SPSS software, version 17.0. The static equilibrium analysis indicated a significant increase in the area and the center of mass offset projected on the ground and the medial-lateral displacement of the spine angle. On the march, there was worsening of spatiotemporal parameters and lower swing in arm ipsilateral to surgery for flexion/extension and abduction/adduction, trunk shows less medial-lateral oscillation. The prosthesis seems to have no influence on balance and gait. The results suggest that unilateral mastectomy can affect the balance and gait.

PURPOSE: The purpose of the study was to examine the relationship between bat swing velocity and lower extremity strength and power in NCAA Division-I softball athletes. METHODS: Twenty-nine softball athletes (age = 19.8 ± 1.3 years, height = 167.9 ± 6.8 cm, mass = 76.4 ± 18.1 kg) participated in the study. Athletes were tested on unloaded and loaded (20kg) squat and countermovement jump peak force, peak power, and jump height performed on a force platform sampling at 1000Hz. During practice, athletes were tested on swing velocity using a timing gate system. Pearson-product moment zero-order correlations were calculated between bat swing velocity and lower extremity strength and power. Statistical significance was set at p≤0.05. RESULTS: Moderate to strong relationships were observed between swing velocity and peak force at all conditions: SJ 0kg (r= 0.51, p= 0.005), SJ 20kg (r= 0.50, p= 0.006), CMJ 0kg (r= 0.44, p= 0.016), CMJ 20kg (r= 0.43, p= 0.022). Additionally, relationships were observed between swing velocity and peak power at all conditions: SJ 0kg (r= 0.45, p= 0.015), SJ 20kg (r= 0.40, p= 0.031), CMJ 0kg (r= 0.53, p= 0.003), CMJ 20kg (r= 0.45, p= 0.015). No statistically significant relationships were observed between swing velocity and jump height. CONCLUSIONS: Swing velocity was related to lower extremity force and power variables. Considering the known effects of strength training on lower extremity strength and power production, these results provide background for inclusion of lower extremity strength training for the development of swing velocity in NCAA Division-I softball athletes.

I address the geometric problem of the pendulum-like swinging of towed birds for AEM platforms. I establish a link between actual observed bird swing and its effect on survey data for two different systems and explain the link by a model that compares actual survey data to the calculated mutual inductance coupling of a dipole pair over an infinitely conductive half space, which pair is permitted arbitrary pitch, roll and altitude changes. I develop a non-linear filter that removes bird swing effects from survey data which successfully corrected data from 3 different AEM surveys. Calibration of several different time domain AEM systems is attempted using an accurately laid out and surveyed, closed, multi-turn loop of known resistance and self-inductance that is placed on - but insulated from - resistive ground. I derive a rigourous mathematical model that predicts airborne receiver's response to the coupling to the transmitter current waveform and total system geometry. The method was proven to be successful over resistive ground, with significant system problems identified such as: altimetry error, spatial averaging of data during postprocessing, error in the predicted horizontal position of the AEM platform, receiver windowing and timing errors and bird swing. I show that, although we can calibrate a time domain AEM system for a single flyover, it is impossible to calibrate an AEM system for geometry. As an intermediate step in the calibration process, I show that by monitoring the current induced in the ground loop we can obtain the waveform of the AEM transmitter current throu gh deconvolution in the Fourier domain. Simple and cost effective methods for the improvement of quantitative AEM data are presented in this thesis. However, until the geometry problem of AEM platforms is solved, full system calibration will not be obtained and filters will need to be applied to the data. I recommend the use of: GPS antennas mounted on all towed birds, able to be post-processed for accurate position recovery, reliable bird-mounted scanning altimeters that do not rely on range-finding technology but instead employ a shortest path algorithm, pitch and roll sensors mounted on the trailed bird and the measurement of airspeed of both the towed bird and the aircraft during surveys.

Since the liberalisation of the energy market in Europe in the early 1990s, much opportunity to trade electricity as a commodity has arisen. One significant consequence of this movement is that market prices have become more volatile instead of its tradition constant rate of supply. Spot price markets have also been introduced, affecting the demand of electricity as companies now have the option to not only produce their own supply but also purchase this commodity from the market. Following the liberalisation of the energy market, hence creating a greater demand for trading of electricity and other types of energy, various types of options related to the sales, storage and transmission of electricity have consequently been introduced. Particularly, swing options are popular in the electricity market. As we know, swing-type derivatives are given in various forms and are mainly traded as over-the-counter (OTC) contracts at energy exchanges. These options offer flexibility with respect to timing and quantity. Traditionally, the Geometric Brownian Motion (GBM) model is a very popular and standard approach for modelling the risk neutral price dynamics of underlyings. However, a limitation of this model is that it has very few degrees of freedom, as it does not capture the complex behaviour of electricity prices. In short the GBM model is inefficient in the pricing of options involving electricity. Other models have subsequently been used to bridge this inadequacy, e.g. spot price models, futures price models, etc. To model risk-neutral commodity prices, there are basically two different methodologies, namely spot and futures or so-called term structure models. As swing options are usually written on spot prices, by which we mean the current price at which a particular commodity can be bought or sold at a specified time and place, it is important for us to examine these models in order to more accurately inculcate their effect on the pricing of swing options. Monte Carlo simulation is also a widely used approach for the pricing of swing options in the electricity market. Theoretically, Monte Carlo valuation relies on risk neutral valuation and the technique used is to simulate as many (random) price paths of the underlying(s) as possible, and then to average the calculated payoff for each path, discounted to today's prices, giving the value of the desired derivative. Monte Carlo methods are particularly useful in the valuation of derivatives with multiple sources of uncertainty or complicated features, like our electricity swing options in question. However, they are generally too slow to be considered a competitive form of valuation, if any analytical techniques of valuation exist. In other words, the Monte Carlo approach is, in a sense, a method of last resort. In this thesis, we aim to examine a numerical method involved in the pricing of swing options in the electricity market. We will consider an existing and widely accepted electricity price process model, use the finite volume method to formulate a numerical scheme in order to calibrate the prices of swing options and make a comparison with numerical solutions obtained using the theta-scheme. Further contributions of this thesis include a comparison of results and also a brief discussion of other possible methods.

As a contribution to the emerging field of practice-based research in the arts, this thesis aims to activate space, experience and the concept in-between. As the in-between cannot be defined ahead of the rhythmic process it carries out and of which it is a part – a rhythm inherent in the city itself and in knowledge production – it is necessary to produce rhythmic relations between bodies, sites and concepts. An art experiment, a forty-two meter high swing mounted on the bridge, Älvborgsbron, in Gothenburg harbour, Sweden, serves as the point of entry to the thesis. A dancer in the swing moved slowly between the bridge and the ground, captured in a rhythmic experience of being earthbound and then weightless. The swing project, together with other rhythmic processes such as walking, weaving and acting physics, activate spatial, temporal and theoretical dimensions of the in-between. Merging my roles as an artist, teacher and researcher by pragmatic production, perception and concepts it becomes possible to transform the rhythms between the examples:   1. A swing mounted on a bridge; one of my art projects. 2. Walking and mapping strategies; as developed in my courses taught at the School of Architecture. 3. The myth about Penelope weaving. 4. Rhythmic relations between bodies and machines at CERN, the particle physics laboratory outside Geneva, a place that is important for several of my art projects.   Creative production aims to expand the capacity of the body.  By employing a bridging structure, spaces in-between are activated thus revealing the power and danger in-between. In that production collective processes merge, creating “social and collective machines” and another reality between:   1. bridge/swing/dancer, 2. map/walking/site, 3. war/loom/weaving, 4. theory/detector/bodies.   These rhythmic processes oscillate between representation and the complex forces of daily activities. However, it is not the rhythm itself that activates spaces in-between but, rather, the changing of directions of the rhythm: from moving to be in motion; from walking forward to walking and falling; from weaving cloth to producing time; from doing physics to acting physics. Activating in-between spaces means activating differences and another way of producing knowledge, a well-known strategy in contemporary art: a production of potential realities, in a constant interaction between concepts and spatial transformations. / QC 20100909

In this thesis, we carefully investigate the electrical characteristics of junctionless vertical MOSFET (JLVMOS) compared with the junctionless planar MOSFET (JLPMOS) and conversional junction vertical MOSFET (JVMOS). Also, we examine the advantages of the double-gate structure and the short-channel behavior of the junctionless transistors. According to the 2D simulation studies, the proposed JLVMOS can achieve better short-channel characteristics (JLVMOS: 62.04 mV/dec S.S., 23.96 mV/V DIBL; JLPMOS: 77.67 mV/dec S.S., 146.07 mV/V DIBL) as compared with the planar transistor, chiefly owing to the double-gate scheme. This proves that only the double-gate device has better gate controllability over the channel region to reduce the short-channel effect. More importantly is that the JLVMOS has a bulk Si starting material, in which the SOI-induced self-heating effects and the fabrication cost can be well suppressed and reduced, respectively. In comparison with the JVMOS, our proposed JLVMOS exhibits better S.S. and reduced DIBL. Furthermore, although the analog/RF properties of the JLVMOS are somewhat degraded, due to its simple fabrication process, our proposed JLVMOS can become one of the mainstream technology for future CMOS applications.

Abstract Four high-performance circuits design techniques for embedded DRAM are proposed. First, a negative voltage generator having high efficiency is proposed to provide the negative voltage for the modified word line driver. The negative voltage generator circuits could be manufactured in n-Well CMOS process, and its operation achieve optimal output voltage. When 2.0-V supplied voltage is applied, the output voltage of -1.6-V is obtained. Even though, the supplied voltage is scaled down to 1.5-V, the output voltage can still achieve -1.05-V. In contrast, the output voltage of traditional one under 2.0-V supplied voltage is only -0.67-V. Second, a fast wordline driver suitable for PMOS pass transistor is proposed. The wordline driver improves the turned-on time by 26.8ns compared with the traditional one and raises the operating speed by 79%. Third, a new reduced clock-swing driver is proposed. Under 2.0-V supplied voltage and 100MHz operating frequency, the total power consumption of the new driver working with RCSFF is reduced by 10% than that of traditional one working with RCSFF. For the above advantage of low power, the new driver is thus more suitable for embedded DRAM applications. Fourth, a modified hierarchical read bus amplifier is proposed. The read bus amplifier is based on the new sense-amplifier. It could drive the output by full-swing voltage. It improves the sensing speed by 2.1ns. And it got the same advantage of no dc idling current as the traditional N&PMOS cross-coupled amplifier. In this thesis, finally, the performance of these circuits is also integrated and examined in an 1-Kbit embedded DRAM test circuit. The simulation RAS access time of 27.9ns is achieved under 2.0V supplied voltage and loading of 16-Mbit embedded DRAM. This indicated the above proposed circuits could be applied in the low voltage and high speed embedded DRAM.
