Dynamic nonlinear pre-distortion of signal generators for improved dynamic range

Jawdat, Suzan January 2009 (has links)
In this thesis, a parsimoniously parameterized digital predistorter is derived for linearization of the IQ modulation mismatch and the amplifier imperfection in the signal generator [1]. It is shown that the resulting predistorter is linear in its parameters, and thus they may be estimated by the method of least-squares. Spectrally pure signals are an indispensable requirement when the signal generator is to be used as part of a test bed. Due to the non-linear characteristic of the IQ modulator and power amplifier, distortion will be present at the output of the signal generator. The device under test was the IQ modulation mismatch and power amplifier deficiencies in the signal generator. In [2], the dynamic range of low-cost signal generators are improved by employing model based digital pre-distortion and the designed predistorter seems to give some improvement of the dynamic range of the signal generator. The goal of this project is to implement and verify the theory parts [1] using data program (Matlab) to improve the dynamic range of the signal generator. The design digital pre-distortion that is implemented in software so that the dynamic range of the signal generator output after predistortion is superior to that of the output prior to it. In this project, we have observed numerical problems in the proposed theory and we have found other methods to solve the problem. The polynomial model is commonly used in power amplifier modeling and predistorter design. However, the conventional polynomial model exhibits numerical instabilities when higher order terms are included, we have used the conventional and orthogonal polynomial models. The result shows that the orthogonal polynomial model generally yield better power amplifier modeling accuracy as well as predistortion linearization performance then the conventional polynomial model.

Potential contribution of African leafy vegetables to the nutritional status of children / J. Osei.

Osei, Jennifer January 2012 (has links)
Background: Children in South Africa are still affected by micronutrient deficiencies and children living in farm communities are especially vulnerable. African Leafy Vegetables (ALVs) are well endowed with micronutrients such as iron, zinc and vitamin A and might contribute to the nutritional status of children. However, these vegetables have been perceived as “poor people’s food” and over the years knowledge of and use of ALVs has decreased. Aim: This study assessed the potential contribution of ALVs to the nutritional status of children in a semi-rural farm community. Method: In this cross-sectional study, anthropometric indices, serum iron, zinc and retinol concentrations were determined in school children aged 5−13 years (n=155). Dietary intake of iron, zinc and vitamin A was evaluated by three 24-hour diet recalls of children (n=154). The iron, zinc and β-carotene content of selected ALVs was determined. Knowledge of and use of ALVs by primary caregivers was established using focus group discussions (FGDs). Descriptive statistics, independent t-tests, the Pearson Chi-Square Test and Mann-Whitney U Test were used. Anthropometric data were analysed using the World Health Organization Reference 2007 data. Dietary data were analysed using FoodFinder (version 3). Qualitative data from FGDs were translated, transcribed and color-coded to generate emerging themes. Results: Stunting (11%) was the most prevalent anthropometric indicator of malnutrition. This was supported by the low socio-economic status of households. Deficiency prevalence in iron (serum ferritin <15 μg/L; 15.5%) and vitamin A (serum retinol <20 μg/dL; 3.2%) was low. Zinc deficiency was the most prevalent (serum zinc <65 μg/dL; 74.8%) deficiency. Median dietary intake of iron, zinc and vitamin A was generally above the Estimated Average Requirement. ALVs were potentially good sources of iron, zinc and β-carotene and could contribute substantially to the Recommended Dietary Allowance for these nutrients in children, without taking into account inhibiting factors that might affect the bioavailability. Iron content of the ALVs studied ranged from 1.4−3.2 mg/100 g edible portion. Amaranthus cruentus was the best source of iron. Zinc content of the ALVs ranged from 0.7−1.4 mg/100g edible portions, with Cleome gynandra having the highest zinc composition. The β-carotene content of the ALVs ranged from 182−314 μg RAE/100 g edible portion, with both Amaranthus cruentus and Cleome gynandra being the best sources. Knowledge of ALVs and their use was indigenous and was transferred between generations. Caregivers had positive attitudes towards the use of ALVs. Conclusion: Although the prevalence of deficiencies was not severe (with exception of zinc deficiency), micronutrient deficiencies exist in the rural farm community studied. ALVs are potentially good sources of iron, zinc and β-carotene and might contribute to the nutritional status of school children. Knowledge of ALVs and the positive attitude and perceptions regarding their use by primary caregivers implied a potentially positive future response to interventions promoting consumption of ALVs in order to contribute to the alleviation of micronutrient deficiencies. / Thesis (MSc (Nutrition))--North-West University, Potchefstroom Campus, 2013.

Individanpassad undervisning : Lärares upplevelser av att anpassa undervisningen efter elverna förutsättningar och behov / Individualized education : Teachers' experiences of adapting teaching to pupils' circumstances and needs

Hansson, Weronica January 2013 (has links)
Läroplanen (Skolverket, 2011) och Skollagen (SFS 2010:800) anger att undervisningen ska individanpassas. Skolinspektionen (2011) fastställer att det finns brister i hur skolorna bedriver en sådan undervisning och även min erfarenhet var att detta inbegrep en del utmaningar. Med detta som bakgrund blev studiens syfte att beskriva, tolka och förstå innebörden i lärares upplevelser av att individanpassa den egna undervisningen samt eventuella relaterade utmaningar. För att undersöka detta användes en kvalitativ metod med intervjuer som datainsamlingsteknik, där fem verksamma lärare intervjuades. En hermeneutiskt-fenomenologisk ansats användes som utgångspunkt. Resultatet visade att individanpassa undervisningen inte är lätt att göra, då det är mycket upp till läraren att själv tolka och bedriva undervisningen med de svårigheter det innebär. Det är många faktorer som är med och påverkar undervisningen och i analysen av resultatet kunde det påvisas att dessa faktorer fungerar i en kombination med varandra och är vad som möjliggör individanpassad undervisning. / The curriculum (Skolverket, 2011) and Education Act (SFS 2010:800) indicates that education must be adapted to the students' abilities and needs. The National Agency for Education (2011) determines that there are deficiencies in how the schools practice such education and also my experience was that this included some challenges. Against this background, this study aim became to describe, interpret and understand the meaning of the teachers’ experiences of individualizes their own teaching and any related challenges. To investigate this, a qualitative method with interviews as a data collection technique was used, where five practicing teachers were interviewed. A hermeneutic - phenomenological approach was used as a base. The results showed that individualized education is not easy to do, as it's much up to the teacher to interpret and carry out the education with the difficulties it means. There are many factors that will affect the education and the analysis of the result show that these factors work in combination with each other and are what enables individualized education.

Desenvolvimento de protocolo para avaliação de sarcopenia por tomografia computadorizada e/ou ressonância magnética / Protocol development for assessment of sarcopenia by computed tomography and / or magnetic resonance imaging

Annelize Serra Negra Dias Mansano 18 July 2016 (has links)
Introdução: A composição corporal nos seres humanos se altera com a idade, mas as causas e consequências dessas mudanças são apenas em parte compreendidas. Uma mudança que é cada vez mais reconhecida por ter efeitos importantes na velhice é a perda de tecidos moles, particularmente de massa muscular esquelética, denominada \"sarcopenia\". Recentemente, tem sido demonstrada a relação entre a composição corporal e estado nutricional do paciente com a evolução e prognóstico em certas doenças. Existem várias estratégias e métodos para avaliação da sarcopenia, incluindo-se a tomografia computadorizada (TC) e a ressonância magnética (RM). Objetivos: Comparar variações das medidas lineares e de área do músculo psoas entre TC e RM, avaliar a variação inter-observador das medidas obtidas e identificar as ações para implantação desta medida nos relatórios de exame, instituindo protocolo de avaliação de sarcopenia para todos pacientes submetidos à TC ou RM de abdome em serviço de imagem. Materiais e métodos: Estudo retrospectivo de pacientes que foram submetidos à TC e RM do abdome, com um intervalo entre os exames de até 7 dias, tendo sido incluídos 47 indivíduos par análise. Os exames foram analisados buscando obtenção das medidas lineares e de área do músculo psoas por dois observadores independentes, utilizando o software de visualização DICOM OsiriX®. Resultados: Não foi observada diferença estatisticamente significante entre as medidas lineares, bem como entre as medidas de área para o mesmo observador na comparação entre TC e RM, com alta concordância entre os métodos. Houve excelente concordância entre os dois observadores para as medidas lineares e de área nos dois métodos. Conclusões: As medidas lineares e de área dos músculos psoas obtidas na TC e na RM são comparáveis, com alta concordância na avaliação pareada, indicando a possibilidade de serem utilizadas de maneira intercambiável na avaliação de sarcopenia. Houve excelente concordância entre os observadores para as medidas lineares e de área dos músculos psoas obtidas na TC e na RM, indicando alta reprodutibilidade. / Introduction: Body composition in humans changes with age, but the causes and consequences of these changes are understood only in part. One change is increasingly recognized to have significant effects on aging is loss of soft tissue, particularly skeletal muscle, called \"sarcopenia\". It has been recently demonstrated the relationship between body composition and nutritional status of the patient with the evolution and prognosis in certain diseases. There are several strategies and methods for evaluation of sarcopenia, including computed tomography (CT) and magnetic resonance imaging (MRI). Purposes: To compare variations of linear measurements and the psoas muscle area between CT and MRI to evaluate the inter-observer variation in measurements obtained and identify the actions to implement this measure in the examination reports, establishing sarcopenia evaluation protocol for all patients undergoing CT or MRI of the abdomen in image service. Methods: Retrospective study of patients who underwent CT and MRI of the abdomen, with an interval between examinations of up to 7 days and were included 47 subjects pair analysis. The tests were analyzed seeking obtain measures and the psoas muscle area by two independent observers, using the visualization software DICOM OsiriX®. Results: There was no statistically significant difference between the linear measurements, and between the area measurements for the same observer in the comparison between CT and MRI with high concordance between the methods. There was excellent agreement between the two observers for linear and area for both methods. Conclusions: The linear measurements and area of the psoas muscles obtained from CT and MRI are comparable with high concordance in paired assessment, indicating the possibility of being used interchangeably in the evaluation of sarcopenia. There was excellent agreement between observers for linear and area of the psoas muscles obtained from CT and MRI, indicating high reproducibility.

It involves theoretical research and of field. The theoretical research developed through the literary revision on the conceptualization of physical deficiency or reduced mobility, the conceptualization of public and private space, the falling, the accessibility and the social inclusion with emphasis in two areas: education and culture. The field research was carried through in two overthrown public buildings, with the application of interviews halfstructuralized with controllers and servers, whose proposal was to investigate the question of the social inclusion for people with physical deficiency or reduced mobility to the place that, for being tumbled, possess specific legislation of conservation, what it can make it difficult the necessary adaptations and the elimination of barriers. Over all, the field research was an indispensable tool to analyze the atitudinal question of controllers and servers in relation to the attendance and the promotion of the accessibility for the people with physical deficiency or mobility reduced in its dependences. The data gotten for the field research had been classified, selected and collated with the theoretical research, becoming after that the analyses. The research concludes that falling cannot be confused with plastering and evidences the necessity and importance of the information, the knowledge and the interactions with people with deficiency as elements facilitators of the felt accessibility in its amplest one. / Este trabalho propõe estudar a inclusão social da pessoa com deficiência física ou mobilidade reduzida em edifícios públicos tombados na cidade de São Paulo. O trabalho envolve pesquisa teórica e de campo. A pesquisa teórica desenvolveu-se através da revisão literária sobre a conceituação de deficiência física ou mobilidade reduzida, a conceituação de espaço público e de espaço privado, o tombamento, a acessibilidade e a inclusão social com ênfase em duas áreas: educação e cultura. A pesquisa de campo foi realizada em dois edifícios públicos tombados, com a aplicação de entrevistas semi-estruturadas com dirigentes e servidores, cuja proposta foi investigar a questão da inclusão social para pessoas com deficiência física ou mobilidade reduzida ao local que, por serem tombados, possuem legislação específica de conservação, o que pode dificultar as adaptações necessárias e a eliminação de barreiras. Sobretudo, a pesquisa de campo foi uma ferramenta indispensável para analisar a questão atitudinal de dirigentes e servidores em relação ao atendimento e a promoção da acessibilidade para as pessoas com deficiência física ou mobilidade reduzida em suas dependências. Os dados obtidos pela pesquisa de campo foram classificados, selecionados e confrontados com a pesquisa teórica, fazendo-se em seguida as análises. A pesquisa conclui que tombamento não pode ser confundido com engessamento e evidencia a necessidade e importância da informação, do conhecimento e das interações com pessoas com deficiência como elementos facilitadores da acessibilidade em seu mais amplo sentido.

Sistema de visão artificial para identificação do estado nutricional de plantas / Artificial vision system for plant nutricional state identification

Alvaro Manuel Gómez Zúñiga 29 March 2012 (has links)
A avaliação do estado nutricional das plantas de milho usualmente é feita através de análises químicas ou pela diagnose visual das folhas da planta, esta última, sujeita a erros de interpretação já que a ausência de algum nutriente na planta gera um padrão de mudança específico na superfície da folha que depende do nível de ausência do nutriente. As dificuldades que apresentam neste processo e sua importância na agricultura, criam a necessidade de pesquisar sistemas automáticos para a avaliação do estado nutricional de plantas. Desta forma, este mestrado teve como objetivo principal o desenvolvimento de um sistema de visão artificial para verificar a possibilidade de identificação de níveis dos macronutrientes Cálcio, Enxofre, Magnésio, Nitrogênio e Potássio em plantas de milho através da análise da superfície das folhas usando métodos de visão computacional. Este projeto realiza uma revisão bibliográfica do estado da arte dos métodos de extração de características de cor, textura em escala de cinza e textura colorida utilizadas em processamento de imagens. A alta similaridade entre os sintomas produzidos pelas deficiências e a pouca similaridade entre amostras de uma mesma deficiência motivou o desenvolvimento de novos métodos de extração de características que pudessem fornecer dados necessários para uma correta separação entre as classes. Os resultados obtidos demonstraram que o sistema desenvolvido possibilita a predição de deficiências nutricionais em estágios iniciais do crescimento da planta usando unicamente a textura da superfície da folha como fonte de informação / The evaluation of the nutritional status of corn plants is usually done through chemical analysis or by visual diagnosis of the plant leaves. Visual diagnosis is subject to misinterpretation as the lack of some nutrient in the plant generates a specific pattern of change in the leaf surface that depends on the degree on which the nutrient is absent on the plant. The difficulties present in this process and its importance in agriculture creates the necessity to search automated systems for the assessment of nutritional status of plants. Thus, this dissertation had as main objective the development of an artificial vision system to verify the possibility of identifying levels of macronutrients calcium, sulfur, magnesium, potassium and nitrogen in corn plants by analyzing the surface of the leaves using computer vision methods. This project performs a review of the literature of the state of the art methods for feature extraction of color, grayscale and colored texture used in image processing. The high similarity between the symptoms caused by deficiencies and low similarity between samples of the same deficiency motivated the development of new methods for extracting features that could provide the data needed for a correct separation between classes. The results showed that the system enables the prediction of nutritional deficiencies in an initial stage of plant growth using only texture of the leaf surface as a source of information

Caracterização do estado nutricional de pacientes de neuropsiquiatria geriátrica: utilização da Mini Avaliação Nutricional - MAN® / Characterization of nutritional status of elderly from an outpatient clinic of geriatric neuropsychiatry: utilization of the Mini-nutritional assessment (MNA)

Amparo Hurtado Fernandez Filha 10 November 2016 (has links)
INTRODUÇÃO: O cuidado nutricional é parte essencial para o acompanhamento integral da crescente população idosa, principalmente quando na presença de doenças crônicas e neurodegenerativas e morbidades psiquiátricas. A Mini Avaliação Nutricional (MAN®), tem sido utilizada para este fim, e em algumas situações, informações adicionais a essa ferramenta são necessárias. OBJETIVOS: Caracterizar o estado nutricional de idosos acompanhados em ambulatório de neuropsiquiatria geriátrica. MÉTODOS: Foi obtida uma amostra de conveniência selecionada aleatoriamente entre pacientes idosos com diagnóstico de depressão (DEP), doença de Alzheimer (DA) e outros transtornos psiquiátricos (OTP). O estado nutricional foi avaliados através da MAN®, pelo índice de massa corporal (IMC= peso/altura2) e pelas circunferências do braço (CB) e panturrilha (CP). Os dados referentes ao consumo de medicamentos também foram obtidos, considerando-se como polifarmácia o consumo de mais de três medicamentos/dia. Os dados de diagnóstico médico e exames laboratoriais foram obtidos do prontuário médico. Foram avaliados 217 indivíduos no total, distribuídos conforme o diagnóstico clínico: grupo DEP= 107 (49,3%); grupo DA=59 (27,2%) e grupo OTP=51 (23,5%). RESULTADOS: O escore da MAN® identificou risco nutricional em 67,3%, 69,5% e 54,9%, e desnutrição em 14,0%, 13,6% e 27,5% dos pacientes em DEP, DA e OTP respectivamente. O baixo peso, avaliado pelo IMC foi observado em 29,0% (DEP), 24,1% (DA) e 45,1% (OTP) dos avaliados. A prevalência de anemia foi de 11,2% (DEP), 10,2% (DA) e 19,6% (OTP); sendo mais frequente em mulheres em DEP e OTP e em homens em DA. A média para vitamina D em todos os grupos encontrava-se na insuficiência. A presença de colesterol total acima dos intervalos de normalidade foi de 47,0% (DEP), 36,3% (DA) e 31,8% (OTP). Foi observada hiperglicemia em 52,9% (DEP), 48,1% (DA) e 41,6% (OTP) dos pacientes. A polifarmácia foi observada em 18,7% (DEP), 15,2% (DA) e 19,6% (OTP). Não houve associação significativa entre o uso de medicamentos e o estado nutricional, embora tenha sido apontado um direcionamento ao risco de desnutrição com o uso de medicamentos para o tratamento da depressão (inibidores seletivos de receptação de serotonina), demências (inibidores de colinesterase), cloridrato de omeprazol e indutores do sono. CONCLUSÕES: o risco nutricional e a desnutrição são prevalentes na população estudada, independente do grupo específico de doença neuropsiquiátrica ou demência. Esses achados demandam e justificam um monitoramento nutricional permanente para esses indivíduos, uma vez que vem acompanhados de outras deficiências específicas que comprometem a saúde de forma geral, como a anemia e insuficiência de vitamina D. A elaboração de planos educativos envolvendo os pacientes, cuidadores e a equipe médica, poderá contribuir para a melhora dessas condições. / INTRODUCTION: Nutritional care is an essential part for the integral follow - up of the growing elderly population, especially in the presence of chronic and neurodegenerative diseases and psychiatric morbidities. The Mini Nutrition Assessment (MAN®) has been used for this purpose, and in some situations, additional information to this tool is necessary. OBJECTIVES: To characterize the nutritional status of elderly patients in a geriatric neuropsychiatry clinic. METHODS: A randomly selected convenience sample was obtained among elderly patients diagnosed with depression (DEP), Alzheimer\'s disease (AD) and other psychiatric disorders (OTP). The nutritional status was evaluated through MAN®, body mass index (BMI = weight / height2) and circumference of arm (CB) and calf (CP). The data referring to the consumption of medicines were also obtained, considering as polypharmacy the consumption of more than three medications/day. The data of medical diagnosis and laboratory tests were obtained from the medical record. A total of 217 individuals were evaluated, distributed according to the clinical diagnosis: DEP = 107 (49.3%); Group DA = 59 (27.2%) and OTP group = 51 (23.5%). RESULTS: The MAN® score identified nutritional risk in 67.3%, 69.5% and 54.9%, and malnutrition in 14.0%, 13.6% and 27.5% of the patients in DEP, DA and OTP respectively. Low weight, evaluated by BMI, was observed in 29.0% (DEP), 24.1% (AD) and 45.1% (BTP) of the evaluated patients. The prevalence of anemia was 11.2% (DEP), 10.2% (AD) and 19.6% (OTP); Being more frequent in women in DEP and OTP and in men in AD. The mean for vitamin D in all groups was in the insufficiency. The presence of total cholesterol above the normality intervals was 47.0% (DEP), 36.3% (DA) and 31.8% (OTP). Hyperglycemia was observed in 52,9% (DEP), 48,1% (AD) and 41,6% (OTP) of the patients. Polypharmacy was observed in 18.7% (DEP), 15.2% (DA) and 19.6% (OTP). There was no significant association between drug use and nutritional status, although there was a trend towards malnutrition with the use of drugs to treat depression (selective serotonin reuptake inhibitors), dementias (cholinesterase inhibitors), Omeprazole hydrochloride and sleep inducers. CONCLUSIONS: nutritional risk and malnutrition are prevalent in the population studied, regardless of the specific group of neuropsychiatric disease or dementia. These findings demand and justify a permanent nutritional monitoring for these individuals, since they are accompanied by other specific deficiencies that compromise health in general, such as anemia and insufficiency of vitamin D. The elaboration of educational plans involving patients, caregivers and The medical team, could contribute to the improvement of these conditions.
