In recent years, research has shown that the issue of security is an essential indicator for public well-being. Along with the advance of science and technology, the application of monitor, which includes the field of crime investigation and prevention, has become more and more importance. Furthermore, the location of monitor is also involved with personal privacy. As a result, it is necessary to prove which one is better for explanation of sense of happiness. Based on the Maslow theory of needs, this study explores the relationship between Kaohsiung resident needs and the installation of monitor in terms of quantitative research methods. For the variable of installation demand, it adopts the way of self-questionnaire mining dimensions including security, social, respect, self-actualization and cognitive needs. After validity analysis, the positive cognitive demand had three factors along with seven independent variables, the reliability above 0.7. Dependent variable of the installation of monitor was adapted from Chinese version of Hu Yan (2000). In this study, the version of SPSS 12.0 software was used for statistical analysis along with Likert scale scores. The higher score of scale is, the more sense of happiness does. After practical analysis, it was found that the people with installed monitor will have higher degree of feeling and safety, not to mention the sense of happiness. They feel that they live in the protection of life and have a sense of accomplishment more than the other events of middle level. In terms of age, work, marriage, positive cognitive and living environment, there is significant difference among them. However, there is no significant difference between monitor alliance and happiness. The study assumed that there are some significant positive correlations among the aspects of safety, community, respect and self-actualization, and it shows that it is necessary to install the street monitor. However, for the aspects of privacy violation as well as stalk information leakage, it was significantly lower degree of positive correlation, indicating the doubtful attitude of public for installation monitor. Therefore, the study infers there might be some impact on personal privacy, so it is necessary to set up stricter management practices on the use of information to alleviate people¡¦s concerns and to prevent people from human rights with law. Within this study, it explains the overall sense of happiness for 72.1%. Maslow's theory is closely linked with the public safety protection measures in life, and it is a practical application. As a result, it proposed the follow-up researchers to delve into the effect of monitor, especially on crime prevention.

This thesis describes an investigation of sub-bandage pressure (SSP). It examines the characteristics of the Strathclyde Pressure Monitor, which incorporates a fluid-filled sensor and a piezo-electric transducer. The sensor volume was minimised, the variation in output with change in sensor position eliminated, and the time response of the system reduced. The impact of changes in foot position on SSP was investigated using two compression bandages. The pressure at a site depended upon the interaction between the type of bandage (elastomeric or non-elastomeric) and the position of the foot. The impact of changes in subject posture on SSP was studied. The SSP increased as the subject stood, from sitting. There was no consistent pattern in pressure change as the subject sat up from lying supine. The sub-bandage pressures of patients with active venous ulcers were monitored at two sites on the leg for seven days. There was a decrease in SSP upon standing, in contrast to normal volunteer studies. Three series of experiments investigated the impact of training in bandaging on SSP. A pilot study of 18 nurses assessed SSP on normal legs before and after training, as well as using a bandage printed with an extension guide. After training, significantly more nurses achieved acceptable pressure profiles. An additional 48 nurses were trained using three bandages (two elastomeric and one non-elastomeric). Training improved bandaging technique but more nurses applied satisfactory bandages with the elastomeric bandages than with the non-elastomeric bandage. In the final investigation, 224 community nurses were trained applying a two-layer and a 4-layer compression system. After training, a higher proportion of nurses applied the 4-layer in a satisfactory manner. This research highlights the different response to posture between patients and normal subjects, and the variable impact of training on nurses depending on the bandage system.

Electrical and Computer Engineering / A high performance, wireless bio-impedance measurement system has been designed for the purpose of monitoring essential electrical properties of the heart during cardiac ablation. The system is broken into three parts: a spring-loaded device to house a tetrapolar surface probe and sensors, a wireless bio-impedance measurement system, and a desktop base station for graphical data display and acquisition. The system is specifically designed for a tetrapolar-electrode configuration where the two outer electrodes served as a current source operating at 20 kHz with an amplitude of 100 µArms and the two inner electrodes served as voltage sensing electrodes. In addition, the system also has a dedicated channel for current sense. The system is designed to be modular and reconfigurable for different measurement needs. Epochs of both discrete voltage and current samples generated by the voltage-controlled current source are processed using a digital signal processing algorithms to generate admittance measurements. In addition to the admittance’s magnitude and phase, pressure, electrocardiogram (EKG), and temperature (two channels) data are also acquired. The measurements are then wirelessly transmitted from the bio-impedance measurement system to a base station where data are processed and viewed graphically. The final system updates the admittance, pressure, EKG, and two temperature channels at 320 Hz, consumes less than 3 W, and has percent of measurement errors of 7 % and 2 % for capacitive and resistive measurements in the range of 100 pF to 10000 pF and 300 Ω to 1600 Ω, respectively. Instrument design, calibration, verification, and modeling are at the heart of this thesis. In the future, the instrument will be deployed for various bio-impedance measurements that require a high degree of linearity, precision, and a wide input range. / text

Trafficking of radioactive material, particularly special nuclear material (SNM), has long been a worldwide concern. To interdict this material the US government has installed radiation portal monitors (RPMs) around the globe. Building materials surrounding an RPM can greatly effect the detector’s background radiation levels due to Naturally Occurring Radioactive Material (NORM). In some cases this effect is so great that the initial RPM setup had to be rebuilt. This thesis develops a methodology for quick and efficient determination of the specific activity and composition of building materials surrounding a RPM to predict background levels, therefore determining the minimum detectable quantity (MDQ) of material. This methodology builds on previous work by Ryan et al by generating material and source cards for a detailed Monte Carlo N-Particle (MCNP) deck, based on an experimental RPM setup to predict the overall gamma background at a site. Gamma spectra were acquired from samples of building materials and analyzed to determine the specific activity of the samples. A code was developed to estimate the elemental composition of building materials using the gamma transmission of the samples. These results were compared to previous Neutron Activation Analysis (NAA) on the same samples. It was determined that densitometry provided an elemental approximation within 5% of that found through NAA. Using the specific activity and material composition, an MCNP deck was used to predict the gamma background levels in the detectors of a typical RPM. These results were compared against actual measurements at the RPM site, and shown to be within 10% of each other.

Purpose: A key objective feature in Restless Legs Syndrome (RLS) is the presence of Periodic Limb Movements (PLMs). The gold standard for documenting PLMs is through polysomnogram (PSG), an overnight sleep study in a sleep laboratory, which is expensive and often inaccessible. This work explored the ability of a portable sleep monitor (PM) to reliably record surface EMG signals, to reliably record limb movements overnight in comparison with PSG, and examined intra- and inter-rater reliability for scoring the PM recordings. Methods: The PM’s surface EMG channel was tested against a standard EMG amplifier by recording bilateral tibialis anterior muscle activity in five healthy participants. It was also tested for recording PLMs simultaneously with polysomnography at Kingston General Hospital with 40 participants referred for screening of sleep disorders. PLMs were scored using standard criteria according to the American Academy of Sleep Medicine Scoring Manual (2007) Analyses: Comparison between the two methods of surface EMG recording was through counts of muscle activity bursts. Comparison of overnight PLM counts was through t-test, Pearson’s r, Intraclass Correlation Coefficient (ICC) and Bland-Altman plots. Intra-rater reliability and inter-rater reliability between two analysts was examined by ICC. Results: Examination of the PM surface EMG recordings demonstrated an exact match of muscle activity counts between the PM and standard EMG recordings. In the PSG study, mean difference between the two PLMI values was +4.8 ± 11.1, t (34) = 2.1, p = 0.04, which was statistically significant and demonstrated systematic over-reporting by the portable monitor. The two PLMI values were strongly correlated, giving a Pearson’s r = .87, p < 0.001. ICC for absolute agreement was 0.87, (95% CI, 0.76 – 0.93), p < 0.001. Bland-Altman analysis gave 95% limits of agreement between the two PLM Indices as +27.9 (95% CI +33.0 to 20.2) to – 19.3 (95%CI -10.6 to -23.4). Conclusions: These data suggest there may be sufficient agreement between PLMI collected by PM and polysomnography to support the use of the PM for measuring PLMs. Further testing should address test retest reliability and examine the performance of the PM in a wider patient population. / Thesis (Master, Rehabilitation Science) -- Queen's University, 2012-08-24 16:40:03.381

A large radiological accident will result in the contamination of surrounding people, animal, vegetation etc. In such a situation assessing of the level of contamination becomes necessary to plan for the decontamination. There are plans existing for evaluating contamination on people. However, there are limited to no plans to evaluate animals. It is the responsibility of the United States Department of Agriculture (USDA) to decontaminate animals. So the objective of this thesis work was to design a scalable gamma radiation portal monitor (RPM) which can be used to assess the level of contamination on large animals like cattle. This work employed a Monte Carlo N-Particle (MCNP) radiation transport code for the purpose. A virtual system of cow, radiation source representing the contamination, cattle chute and different detector configurations were modeled. NaI scintillation detectors were modeled for this work. To find the optimal detector size and configuration, different detector orientations were simulated for different source positions using the MCNP code. Also simulations were carried out using different number and size of the detectors. It was found that using 2" x 4" x 16" detector yielded a minimum detectable activity (MDA) value of 0.4 microCi for 137Cs source.

O uso dessa tecnologia facilita estabelecer corretamente a deposição de sementes no solo, minimizando os prejuízos durante o estabelecimento da lavoura. Esse trabalho teve como objetivo avaliar dois tipos de sensores para monitores de semeadura (com fio e sem fio), por meio da distribuição de sementes de duas culturas (milho e soja) utilizando dois tipos de semeadoras, com mecanismo dosador de discos horizontal e pneumático, a fim de identificar a eficiência de cada tipo de sensor, os quais foram utilizados em cinco diferentes velocidades de deslocamento. O ensaio foi conduzido em 2017, na Fazenda Experimental Lageado, pertencente à Faculdade de Ciências Agronômicas – UNESP, localizada no município de Botucatu – SP. O delineamento experimental foi em blocos, em um fatorial 2x2x5. As sementes foram coletadas em embalagens plásticas, fixadas na saída do tudo condutor de sementes da semeadora. Após a coleta, as sementes foram contadas através de um contador digital, para avaliar a eficiência dos sensores de semeadura, sendo a quantidade de sementes registradas pelo monitor, comparada com os dados reais. O sensor com fio apresentou melhores resultados de precisão quando foi utilizado sementes de milho. Já o sensor sem fio obteve acurácia superior quando se trabalhou com as sementes de soja. Quanto maior a velocidade de deslocamento, menor será o índice de precisão de leitura para ambos os sensores. Ao utilizar a semeadora com mecanismo dosador pneumático, é possível trabalhar em velocidades mais elevadas, obtendo bons índices de precisão dos sensores / Between many technologies used to achieve uniformity in seed distribution, the use of sensors with optical readers is an option.

This fieldwork aimed to evaluate two types of sensors by sowing monitors (wired and wireless), by means of the distribution of seeds of two crops (corn and soybean) using two types of seeders, with metering mechanism horizontal plate and pneumatic, with the objective of identifying the efficiency of each type of sensor, which were used at five different displacement speeds. The test was conducted in may 2017 at the Lageado Experimental Farm, belongs to Faculty of Agronomic Sciences – UNESP located in Botucatu – SP. The experimental design was in a factorial 2x2x5. The seeds were collected in plastic bags attached to the seeder seed tube. After the collect, the seeds were counted through a digital counter, to evaluate the efficiency of sowing sensors, being that data compared with the actual data. The wired sensor got better precision indices when corn seeds were used. The wireless sensor got better precision indices when soybean seeds were used. The higher the travel speed displacement speed, less will be the reading accuracy index for both sensors. When was use the pneumatic metering mechanism, it is possible to work to using higher speeds, getting better precision indices of the optical sensors

Em 20% dessas amostras a concentração de microcistina foi superior a 1,0 &#956;g/L, valor máximo permitido pela Legislação Brasileira, para águas de abastecimento público. Poucos laboratórios no estado do Espírito Santo apresentam infraestrutura para a análise de microcistinas e, além disso, os atuais métodos quantitativos são onerosos e demorados. Com o objetivo principal de desenvolver um sistema de detecção de microcistinas, neste estudo foi validado um método quantitativo por cromatografia líquida de alta eficiência (CLAE) e desenvolvido um sistema qualitativo (P/A) para análise da cianotoxina. Na validação um método livre de acetonitrila demonstrou seletividade e linearidade para separar e quantificar diferentes variantes de microcistina (-RR, -YR, -LR e -LA). Níveis de recuperação entre 98,2 e a 106,1% demonstraram a precisão e os limites de detecção (entre 0,17 e 0,25 &#956;g/L) e quantificação (entre 0,55 e 0,82 &#956;g/L) atenderam aos limites nacionais e internacionais de potabilidade. O sistema qualitativo (P/A) desenvolvido mostrou-se de fácil execução, baixo custo e alta sensibilidade, permitindo a determinação visual direta da presença de microcistinas em concentrações acima de 0,80 &#956;g/L, sem a necessidade de nenhum método de processamento, concentração ou limpeza da amostra. Comparado com métodos de tradicionais de detecção de microcistinas, ELISA e CLAE (HPLC), o sistema demonstrou taxas de confiabilidade de 82,4% e 88,2%.
