In radars, matched filters are used in the receiver of the system. Since the target velocity is not known a priori, degradation occurs due to mismatch of the return signal and the matched filter. The performance of the radar can be improved by using a bank of matched filters. The first topic investigated in this work is optimization of the bank of matched filter structure. Two methods are proposed for the design of the parallel filter structure and computations are performed with both methods. The output signal of a radar receiver filter consists not only of the main peak from the target but also of range sidelobes. In a multi-target radar environment, the sidelobes of one large target may appear as a smaller target at another range, or the integrated sidelobes from targets or clutter may mask all the information of another target. The second part of this thesis discusses the methods for decreasing the sidelobe level of the receiver output. Two methods are studied for this purpose. The first is the classical amplitude weighting and the second is the use of an inverse filter that minimizes total sidelobe energy. Both methods decrease the sidelobe levels while bringing a mismatch loss and main peak broadening. For the inverse filter case it is observed that the effect of inverse filter becomes evident as the filter length is increased beyond some point. Finally, the effects of quantization on video signal and the receiver filter coefficients are evaluated. It is observed that 16 bits quantization is sufficient for all kinds of receiver filters tested.

本研究以某醫院為例，探討議題如下： (一)個案醫院導入平衡計分卡之需求、過程以及所遭遇之問題。 (二)將層級分析法(Analytic Hierarchy Process, AHP)與平衡計分卡指標權重設定相結合，以釐清多重指標之下，各個指標之相對權重關係，避免過多指標對指標管理造成混淆的抵銷影響。 分析結果顯示：個案醫院護理部門平衡計分卡五大構面中以學習與成長構面為最重要，顯示個案醫院護理部門對專業知識的重視。此外，平衡計分卡各構面之策略性衡量指標以顧客構面之住院病人整體滿意度策略性衡量指標權重最高，其次依序為學習與成長構面之舉辦護理使命共識營參與人數、內部流程構面之病房危機應變作業完成率、社會承諾構面之安寧照護推廣活動、財務構面之未達使用件年限之財產報銷金額占總報銷金額之比率。 / This study uses a medical center in Taiwan as a case study subject, and discusses the following issues: 1. Understanding why and how the subject hospital uses balanced scorecard at the organization and divisional levels. 2. Integrating Analytic Hierarchy Process (AHP) with balanced scorecard to clarify the relative weighting relationship among different strategic measures. The balanced scorecard performance measurement system of the subject hospital includes twenty-four strategic measures. The study adopts Analytic Hierarchy Process approach to solve the measurement problems from the nursing department of the subject hospital. The results show that the learning and growth dimension was the most important factors to achieve the strategic goal of the subject nursing department. Besides, customer satisfaction measure received a weight of 8.940% out of the twenty-four measures, which means that the nursing department members consider the customer satisfaction measure as the most important measure, so the strategic action plan for the customer satisfaction should be implemented first.

This thesis describes the design, maintenance and statistical analysis involved in undertaking a Longitudinal Survey. A longitudinal survey (or study) obtains observations or responses from individuals over several times over a defined period. This enables the direct study of changes in an individual's response over time. In particular, it distinguishes an individual's change over time from the baseline differences among individuals within the initial panel (or cohort). This is not possible in a cross-sectional study. As such, longitudinal surveys give correlated responses within individuals. Longitudinal studies therefore require different considerations for sample design and selection and analysis from standard cross-sectional studies. This thesis looks at the methodology for analysing social surveys. Most social surveys comprise of variables described as categorical variables. This thesis outlines the process of sample design and selection, interviewing and analysis for a longitudinal study. Emphasis is given to categorical response data typical of a survey. Included in this thesis are examples relating to the Goodna Longitudinal Survey and the Longitudinal Survey of Immigrants to Australia (LSIA). Analysis in this thesis also utilises data collected from these surveys. The Goodna Longitudinal Survey was conducted by the Queensland Office of Economic and Statistical Research (a portfolio office within Queensland Treasury) and began in 2002. It ran for two years whereby two waves of responses were collected.

In the first part, we introduce the round sorting problem (RSP), which models the minimization of the usage of buffer for the temporary storage of packets to be forwarded in TDMA communications of wireless mesh networks. We present a complete foundation for the definition of the RSP, and show that the problem is NP-hard for two theoretical models of radio interference known in the literature. A mixed integer programming formulation is also presented for a purely combinatorial and applicationindependent generalization of the RSP, the SMSP problem. In the second part of the work, we deal with problems about queries on insertions into sequences of numbers. Our main result in this part of the thesis is to show how, after a preprocessing step which runs in linear time on a sequence A of arbitrary real numbers, it is possible to compute in constant time the greatest sum of a (circular or not) contiguous subsequence of the sequence which results from the insertion of a given real number x into a given position p of A. In the third part of the thesis, we use the query algorithms from the second part to obtain an efficient implementation of the GRASP metaheuristic applied to the SMSP problem. An experimental analysis of this implementation is described, in which the values of the solutions returned by the metaheuristic are compared with those of the solutions obtained through the mixed integer formulation, in the case of small instances, and with the available lower bound, in the case of larger instances. / Esta tese é composta de três partes bem-delineadas. Na primeira parte, nós introduzimos o "problema de ordenação de rodadas" (POR), que modela a minimização do uso de memória ("buffer") para o armazenamento temporário de pacotes a serem repassados em comunicações TDMA de redes de rádio em malha. Nós apresentamos uma fundamentação completa para a definição do POR, e mostramos que o problema é NP-difícil para dois modelos teóricos de interferência de rádio conhecidos na literatura. Uma formulação de programação inteira mista é também apresentada para uma generalização puramente combinatória e independente de aplicação do POR, o problema SMSP. Na segunda parte do trabalho, nós abordamos problemas de consulta sobre inserções em sequências de números. O nosso principal resultado nesta parte da tese é mostrar como, após um passo de pré-processamento que executa em tempo linear sobre uma sequência "A" de números reais quaisquer, é possível computar em tempo constante a maior soma de uma subsequência contígua (circular ou não) da sequência que resulta da inserção de dado um número real "x" numa dada posição "p" de "A". Na terceira parte da tese, nós utilizamos os algoritmos de consulta da segunda parte para obter uma implementação eficiente da meta-heurística GRASP aplicada ao problema SMSP. Uma análise experimental dessa implementação é descrita, onde os valores das soluções retornadas pela meta-heurística são comparados com os das soluções obtidas pela formulação inteira mista, no caso de instâncias pequenas, e com o limite inferior disponível, no caso de instâncias maiores.

For this, two studies are presented. The first study describes the method used for the kinematic analysis of kicking movements in infants. In the study, four infants were longitudinally videotaped at ages from one to six months and analysis was performed on the Dvideow system. It was verified that the use four video cameras was required. Moreover, six plumb lines were used to calibrate the system and ensure an accuracy of 2 mm. It was concluded, based in the first estudy that the use of the Dvideow system to perform kinematic analysis of the kicking movement in infants proved to be appropriate and feasible. The second study aimed to verify the influence of weights of 1/10 e 1/3 the mass of lower limb in the pattern of the kicking movements of infants in the first four months of life. Fourteen healthy infants participated in the study, longitudinally videotaped. Kicking frequency, foot/panel contact frequency, intralimb coordination pattern, movement time, average speed and straightness index were analyzed. Comparing the ages, we found differences in the kicking frequency, foot/panel contact frequency, movement time, and average speed. Comparing the weighting conditions, we found changes in the kicking frequency and foot/panel contact frequency; the kinematic variables remained unchanged. Therefore, we suggest that during the first four months of life, infants change the kicking frequency according to their ages, the intra-session training and additional weighting. These features are probably the result of intrinsic factors such as increased mass and muscle strength, behavior status of infants, maturation of the Central Nervous System and extrinsic factors such as the weight and the interest in the environment and in performing the proposed task. / Este trabalho teve por objetivos descrever o método utilizado para análise cinemática dos chutes e verificar os efeitos do peso adicional no padrão dos chutes nas idades de um a quatro meses de vida. Para tanto, são apresentados dois estudos. O primeiro estudo descreve o método empregado para análise da cinemática dos movimentos de chutes de lactentes. Neste estudo, quatro lactentes foram filmados longitudinalmente nas idades de um a seis meses e a análise foi realizada no sistema Dvideow 6.3. Foi verificado que o uso de quatro câmeras de vídeo é necessário. Além disso, utilizamos seis fios de prumo para calibrar o sistema e garantir uma precisão de 2mm. Portanto, concluímos, com base no primeiro estudo, que a utilização do sistema Dvideow para realizar a análise cinemática dos chutes de lactentes mostrou-se adequada e viável. O segundo estudo teve por objetivo verificar a influência de pesos de 1/10 e 1/3 da massa do membro inferior no padrão dos chutes de lactentes de um a quatro meses de vida. Participaram deste estudo 14 lactentes, filmados longitudinalmente. Foram analisadas as variáveis frequência de chutes, freqüência de contato do pé com o painel, padrão de coordenação intramembro, tempo de movimento, velocidade média e índice de retidão. Quando consideramos as idades, verificamos diferença na freqüência de chutes, na freqüência de contatos do pé com o painel, no tempo do movimento e na velocidade média. Quando comparamos as condições de peso, verificamos alteração da freqüência de chutes e da freqüência de contatos do pé com o painel; as variáveis cinemáticas mantiveram-se inalteradas. Portanto, podemos sugerir que no decorrer dos quatro primeiros meses de vida, os lactentes alteram a freqüência dos chutes em função das suas idades, do treinamento intra-sessão e do peso adicional. Essas características são, provavelmente, resultado de fatores intrínsecos, como aumento da massa e força musculares, estado comportamental dos lactentes, maturação do Sistema Nervoso Central e fatores extrínsecos como o peso e o interesse pelo ambiente e em realizar a tarefa.

The dimension of its importance demands from legal systems specific regulations which give them a role towards public interest. At the same time, the media are an object of dispute between the society antagonistic political projects. This paper seeks to contribute to legal debate on the right to communication, specifically on media activity regulation. We start from the comparative analysis between decisions of the Corte Suprema de Justicia de la Nación Argentina (CSJN), that in special proceedings for declaratory action of unconstitutionality, recognized the constitutionality of Ley de Medios, regulatory framework for audiovisual communication in the country, and the Supremo Tribunal Federal (STF), which, in ADPF 130, declared the non- receipt of the Press Law. In both lawsuits, it was possible to realize the conceptual, political and legal influences that prevaled in each court. The CSJN, through the weighting technique, confronted the principles of property rights, alleged by the applicants of the contestation, and the collective freedom of speech, right declared as objective in the Ley de Medios. The Argentine Court assigns greater weight to collective freedom of speech, showing alignment to the principles of self reliance, guiding paradigm of communication field. The STF, by its turn, confronting the freedom of press to the personality rights and the State regulatory activity, gave prevalence to the first. However, despite the majority decision for ADPF 130´s approval, disputes concerning the grounding were raised. The lawsuit trial criated a legislative gap on the appliance of the right of reply, and forwarded the media activity deregulation process, which is part of the free flow of information proposal, paradigm that reflects the idea of free market to the media field. / Os meios de comunicação social são instrumentos que exercem considerável influência nos campos político, econômico e cultural. A dimensão de sua importância demanda dos ordenamentos jurídicos a elaboração de regramentos que lhes atribuam papéis voltados ao interesse público. Ao mesmo tempo, os meios de comunicação são objeto de disputa entre os projetos políticos antagônicos na sociedade. Este trabalho procura contribuir com o debate jurídico sobre o direito à comunicação, especificamente em relação à regulamentação da atividade midiática. Partimos da análise comparativa entre as decisões da Corte Suprema de Justícia de la Nación Argentina (CSJN), que, em recurso extraordinário de ação declaratória de inconstitucionalidade, reconheceu a constitucionalidade da Ley de Medios, marco regulatório da comunicação audiovisual no país, e do Supremo Tribunal Federal (STF), que, na ADPF 130, declarou a não-recepção da Lei de Imprensa. Nas duas ações, foi possível perceber as influências conceituais, políticas e jurídicas que alcançaram prevalência em cada Corte. A CSJN, através da técnica da ponderação, confrontou os princípios dos direitos patrimoniais, alegados pelas empresas autoras da impugnação, e a liberdade de expressão coletiva, direito declarado como objetivo da Ley de Medios. A Corte argentina atribui maior peso à liberdade de expressão coletiva, evidenciando alinhamento aos princípios da self reliance, paradigma orientador do campo comunicacional. O STF, por sua vez, confrontando a liberdade de imprensa com os direitos de personalidade e a atividade regulamentar do Estado, conferiu prevalência à primeira. No entanto, a despeito da decisão majoritária pelo deferimento da ADPF 130, foram levantadas divergências relativas à fundamentação. O julgamento da ação gerou um vazio legislativo quanto ao exercício do direito de resposta, e avançou no processo de desregulamentação da atividade midiática, que faz parte da proposta do free flow of information, paradigma que traduz a ideia de livre mercado para o campo da comunicação social.

O objetivo desta tese é investigar aspectos práticos que facilitem a aplicação da teoria de controle H1 não linear em projetos de sistemas de controle. A primeira contribuição deste trabalho é a proposta do uso de funções ponderação com dinâmica no projeto de controladores H1 não lineares. Essas funções são usadas no projeto de controladores H1 lineares para rejeição de perturbações, ruídos, atenuação de erro de rastreamento, dentre outras especificações. O maior obstáculo para aplicação prática da teoria de controle H1 não linear é a dificuldade para resolver simultaneamente as duas equações de Hamilton-Jacobi-Isaacs relacionadas ao problema de realimentação de estados e injeção da saída. Não há métodos sistematicos para resolver essas duas equações diferenciais parciais não lineares, equivalentes µas equações de Riccati da teoria de controle H1 linear. A segunda contribuição desta tese é um método para obter a injeção da saída transformando a equação de Hamilton-Jacobi-Isaacs em uma sequencia de equações diferenciais parciais lineares, que são resolvidas usando o método de Galerkin. Controladores H1 não lineares para um sistema de levitação magnética são obtidos usando o método clássico de expansão em série de Taylor e o método de proposto para comparação. / The purpose of this thesis is to investigate practical aspects to facilitate the ap- plication of nonlinear H1 theory in control systems design. Firstly, it is shown that dynamic weighting functions can be used to improve the performance and robustness of the nonlinear H1 controller such as in the design of H1 controllers for linear plants. The biggest bottleneck to the practical applications of nonlinear H1 control theory has been the di±culty in solving the Hamilton-Jacobi-Isaacs equations associated with the design of a state feedback and an output injection gain. There is no systematic numerical approach for solving this ¯rst order, nonlinear partial di®erential equations, which reduces to Riccati equations in the linear context. In this work, successive ap- proximation and Galerkin approximation methods are combined to derive an algorithm that produces an output injection gain. Design of nonlinear H1 controllers obtained by the well established Taylor approximation and by the proposed Galerkin approxi- mation method applied to a magnetic levitation system are presented for comparison purposes.

Abstract Study samples in medical research are selected according to the objectives of the studies. Researchers seek to collect data as extensively and reliably as possible. In practice, however, data are often missing or may be incorrect. This thesis covers some of the problems concerning missing data and data collection in psychiatric research. Methods for adjusting for missing data and for evaluating the reliability of data are presented. The data originate from the Northern Finland 1966 Birth Cohort (N = 12058). This study explored how participation in an epidemiologic study that includes questionnaires and a clinical examination is affected by mental health (N = 11540), and whether non-participants experience more severe clinical symptoms than participants in a psychiatric field study (N = 145) among subjects with a psychosis. Inverse probability weighting (IPW) was used to adjust for non-participation in comparisons of brain volumes between schizophrenia and control groups. The precision of self-reported medication use was also explored (N = 7625). In an epidemiologic study of all cohort members, subjects with a psychiatric disorder participated less actively than those without one. In the psychiatric field study, non participants were more often patients with schizophrenia than other psychoses. The psychiatric symptoms of non-participants were more severe and they needed more hospital care than participants. The use of IPW led to higher estimates of cerebrospinal fluid volume and lower estimates of grey and white matter volumes in schizophrenia patients, and increased the statistical significance of the differences in brain volume estimates between the schizophrenia and control groups. The precision of self-reported data on psychoactive medication use was substantial. Due to non-participation, the true prevalence of psychiatric disorders is probably higher than the prevalence estimates from field studies that are based on data provided by participants only. In order to reflect the true differences in the target population, weighting methods can be used to improve estimates affected by non-participation. Regarding psychoactive medication use, data collected by postal questionnaire can be assumed accurate enough for study purposes. However, it may underestimate the prevalence of medication use due to non-participation. / Abstract Tutkimusaineisto valitaan tutkimuksen tavoitteiden perusteella. Tavoitteena on kerätä kattava ja virheetön aineisto. Käytännössä kuitenkin osa tiedoista voi puuttua tai olla virheellistä. Tässä väitöskirjassa esitellään yleisesti menetelmiä huomioida puuttuva tieto analyyseissä ja arvioida aineistojen luotettavuutta psykiatrisessa tutkimuksessa. Aineisto perustuu Pohjois-Suomen vuoden 1966 syntymäkohorttiin (N = 12058). Väitöskirjassa tutkittiin, miten psykiatrinen sairastavuus vaikuttaa osallistumiseen epidemiologisessa tutkimuksessa, joka sisälsi kyselyitä ja terveystutkimuksen (N = 11540), sekä erosiko psykiatriseen kenttätutkimukseen osallistuneiden ja osallistumattomien psykoosipotilaiden kliininen taudinkuva toisistaan (N = 145). Käänteisen todennäköisyyden painotusmenetelmää käytettiin korjaamaan puuttuvan tiedon aiheuttamaa virhettä aivovolyymien estimaateissa skitsofreniapotilailla. Lisäksi arvioitiin itse ilmoitetun lääkekäyttötiedon luotettavuutta (N = 7625). Epidemiologisessa tutkimuksessa ne kohortin jäsenet, joilla oli jokin psykiatrinen sairaus, osallistuivat passiivisemmin kuin ne, joilla ei ollut psykiatrista sairautta. Psykoosipotilaat, jotka eivät osallistuneet psykiatriseen kenttätutkimukseen, sairastivat tutkimukseen osallistuneita useammin skitsofreniaa kuin muita psykooseja ja heidän taudinkuvansa oli vakavampi. Painottaminen kasvatti aivonesteen ja alensi harmaan ja valkean aineen tilavuuksien estimaatteja skitsofreniapotilailla, ja lisäsi aivovolyymien erojen tilastollista merkitsevyyttä skitsofreniapotilaiden ja vertailuhenkilöiden välillä. Itse ilmoitetun psykoaktiivisten lääkkeiden käyttötiedon luotettavuus oli merkittävä. Kadosta johtuen psykiatristen sairauksien todellinen vallitsevuus on todennäköisesti korkeampi kuin vallitsevuuden estimaatit, jotka on laskettu tutkimukseen osallistuneiden tiedoista. Painotusmenetelmiä voidaan käyttää parantamaan puuttuvan tiedon vääristämiä estimaatteja, koska painottamalla huomioidaan todellisia eroja kohdeväestössä. Tutkittaessa lääkekäyttötietoa postikyselyillä kerätyn aineiston voidaan olettaa olevan laadultaan riittävä tutkimustarpeisiin.

In this thesis, we discuss calibration estimation in the presence of nonresponse with a focus on the linear calibration estimator and the propensity calibration estimator, along with the use of different levels of auxiliary information, that is, sample and population levels. This is a fourpapers- based thesis, two of which discuss estimation in two steps. The two-step-type estimator here suggested is an improved compromise of both the linear calibration and the propensity calibration estimators mentioned above. Assuming that the functional form of the response model is known, it is estimated in the first step using calibration approach. In the second step the linear calibration estimator is constructed replacing the design weights by products of these with the inverse of the estimated response probabilities in the first step. The first step of estimation uses sample level of auxiliary information and we demonstrate that this results in more efficient estimated response probabilities than using population-level as earlier suggested. The variance expression for the two-step estimator is derived and an estimator of this is suggested. Two other papers address the use of auxiliary variables in estimation. One of which introduces the use of principal components theory in the calibration for nonresponse adjustment and suggests a selection of components using a theory of canonical correlation. Principal components are used as a mean to accounting the problem of estimation in presence of large sets of candidate auxiliary variables. In addition to the use of auxiliary variables, the last paper also discusses the use of explicit models representing the true response behavior. Usually simple models such as logistic, probit, linear or log-linear are used for this purpose. However, given a possible complexity on the structure of the true response probability, it may raise a question whether these simple models are effective. We use an example of telephone-based survey data collection process and demonstrate that the logistic model is generally not appropriate.

This thesis gives an example of how decision analytic methods can be applied to choices in the adoption of cloud computing. The lifecycle of IT systems from planning to retirement is rapidly changing. Making a technology decision that can be justified and explained in terms of outcomes and benefits can be increasingly challenging without a systematic approach underlying the decision making process. It is proposed that better, more informed cloud adoption decisions would be taken if organisations used a structured approach to frame the problem to be solved and then applied trade-offs using an additive utility model. The trade-offs that can be made in the context of cloud adoption decisions are typically complex and rarely intuitively obvious. A structured approach is beneficial in that it enables decision makers to define and seek outcomes that deliver optimum benefits, aligned with their risk profile. The case study demonstrated that proven decision tools are helpful to decision makers faced with a complex cloud adoption decision but are likely to be more suited to the more intractable decision situations.
