Grace a son imagination debridee et sa pensee extravagante. Naguib mahfouz a su exploiter les traditions religieuses populaires et litteraires pour en faire le point de depart de deviances systematiques et nous produire un chef-d'oeuvre nomme a awlad haratina. C'est a ce roman que nous avons consacre cette etude. Notre these presente donc une analyse globale de la structure interne des cinq recits qui composent awlad haratina. C'est un travail qui privilegie certains mecanismes du recit qui jouent le role de principes unificateurs de noyaux d'agregation-organisation des textes dont ils presentent par consequent la charpente narrative. Cette etude s'interesse aussi au temps, mais de deux facons differentes : la premiere, basee sur l'ecoulement irreversible des evenements, l'autre preferantcommencer par la confrontation de plusieurs textes du roman dans le but d'emanciper l'ecriture mahfuzienne en y decelant une thematique recurrente relative au temps diurne ou nocturne.

The present study aims to understand the dialectal accommodation process of paraibanos who live in Recife (PE), based on Communication Accommodation Theory (GILES et al., 1987) and in the theoretical-methodological contributions of the Variation Theory (LABOV, 1996; 1972). The phonological phenomenon which will allow us to check the accommodation effects is the realization of coronal fricative /S/ in coda position by the fact that this segment clearly marks the difference between the dialects under study. The corpus was constituted by 9 paraibanos informants residing for at least two years in Recife. The collected data were analyzed quantitatively and qualitatively. The quantitative analysis enabled us to identify statistically the factors that are contributing to the accommodation, while the qualitative analysis enabled us the interpretation of subjective data that contributed to the accommodation of the new dialect or the preservation of the dialect of origin. The statistical treatment realized through Goldvarb X (SANKOFF, TAGLIAMONTE & SMITH, 2005) showed, in increasing order of significance, which the most relevant variables were: permanence time, amount of exposure to dialect, following phonological context, the style and the frequency of visits. The qualitative analysis developed through the participants speech allowed us identify the linguistics attitude of the informants. We realized that positive evaluation influenced the linguistic accommodation even as the negative evaluation led them to preserve their dialect of origin as a way of distancing.
O presente estudo visa compreender o processo de acomodação dialetal de paraibanos que vivem em Recife (PE), com base na Teoria da Acomodação da Comunicação (GILES et al., 1987) e nos aportes teórico-metodológicos da Teoria da Variação Linguística (LABOV, 2008; 1972). O fenômeno fonológico que nos permitirá verificar os efeitos da acomodação é a realização da fricativa coronal /S/ em posição de coda silábica, pelo fato de que esse segmento marca claramente a diferença entre os dialetos em estudo. O corpus foi constituído por 9 informantes paraibanos que residem há no mínimo dois anos em Recife. Os dados coletados foram analisados quantitativamente e qualitativamente. A análise quantitativa possibilitou identificar estatisticamente os fatores que estão contribuindo para a acomodação, enquanto a análise qualitativa possibilitou a interpretação dos dados subjetivos que contribuíram para a acomodação do novo dialeto ou a preservação do dialeto de origem. O tratamento estatístico realizado através do Goldvarb X (SANKOFF, TAGLIAMONTE & SMITH, 2005) mostrou, em ordem crescente de significância, que as variáveis mais relevantes foram: o tempo de permanência, o contato diuturno com falantes recifenses, o contexto fonológico seguinte, o estilo e a frequência das visitas. A análise qualitativa desenvolvida através das falas dos participantes permitiu-nos identificar a atitude linguística dos informantes. Percebemos que a avaliação positiva influenciou a acomodação linguística, assim como a avaliação negativa levou-os à preservação do seu dialeto de origem, como forma de distanciamento.

A pesquisa aqui apresentada baseou-se no pressuposto de que todo processo de vida constituiu-se em um processo formativo. A partir disso, pelo viés da história de vida como caminho teórico metodológico, buscou-se entender a maneira pela qual uma professora aposentada revela suas experiências de formação e de aprendizagens. A indagação central foi assim formulada: como a professora concebe a docente que foi se constituindo no cotidiano, nas práticas e pelas práticas? Objetivou-se compreender a trajetória profissional, desenrolada na cidade de Jacarezinho-PR, no período de 1954 a 2007, a partir da história de vida de uma professora aposentada, entendendo o seu processo de formação e prática docentes, carregadas de sentidos e significados atribuídos ao exercício de "ser professora". A pesquisa, de abordagem qualitativa, centra-se na análise das narrativas produzidas pela professora. Três temáticas foram tratadas na pesquisa, em concomitância às narrativas da professora: história de vida, com base em autores como Gaston Pineau, Jean-Louis Le Grand (2012); Christine Delory-Momberger (2008); memória, tratada a partir de Maurice Halbwachs (2006); Henri Bergson (1999); Michael Pollak (1989); Ecléia Bosi (1983); formação de professores, abordada a partir de António Nóvoa (1993); Maurice Tardif (2002). Concluímos que a trajetória de vida de uma professora é um caminho possível para se compreender os pressupostos sobre os quais a realidade vai se construindo e coloca o sujeito como produtor e produto histórico da sociedade. Os resultados apontam para elementos significativos, como a valorização da professora por sua profissão; reconhecimento pelo seu trabalho, qualidade na sua formação, respeito pelo aluno e pontos de continuidade e rupturas no processo de constituir-se professora.
The research presented here was based on the assumption that every process of life consisted in a training process. From this, the life history as a methodological bias theoretical way, we sought to understand the way in which a retired teacher reveals her experiences of training and learning. The central question was worded as follows: as the teacher sees the teacher who was constituted in everyday life practices and practices? This study aimed to understand the professional trajectory, peeled in the city of Jacarézinho - PR, in the period 1954-2007, from the life story of a retired teacher, understanding the process of training and practice teacher, loaded with meanings and meanings assigned the exercise of "a teacher". The research adopted a qualitative approach, focuses on the analysis of the narratives produced by the teacher. Three issues were addressed in the research, concomitantly to the narratives of the teacher: life story , based on authors like Gaston Pineau, Jean - Louis Le Grand (2012); Christine Delory - Momberger (2008); memory, addressed from Maurice Halbwachs (2006); Henri Bergson 1999); Michael Pollak (1989); Ecléia Bosi (1983); teacher education , approached from Antonio Nóvoa (1992); Maurice Tardif (2002). We conclude that the trajectory of the life of a teacher is a possible way to understand the assumptions upon which reality is being built and put the subject as producer and historical product of society. The results point to significant elements such as the enhancement of teacher by profession; recognition for their work, quality in their training, respect for student and points of continuity and ruptures in the process be a teacher.

As indústrias de curtimento de couros eliminam grande quantidade e diversidade de contaminantes nos ecossistemas aquáticos e ainda apresentam a problemática decorrente da utilização do cromo no tratamento do couro. Com isso, o objetivo geral desta dissertação foi a aplicação de parâmetros bioquímicos e genotóxicos dos teleósteos Prochilodus lineatus e Serrapinnus notomelas, submetidos a testes in situ, para avaliar a qualidade do rio Bandeirantes do Norte (Rolândia-PR, Brasil), o qual recebe efluentes líquidos de um curtume. Para isso foi realizado um trabalho com juvenis de P. lineatus submetidos a testes in situ no rio Bandeirantes do Norte, durante o inverno, no qual foram analisados biomarcadores bioquímicos e genotóxicos, acúmulo de cromo nos tecidos dos peixes e a concentração de cromo na água e sedimento. Os pontos selecionados foram: ponto A - a montante do curtume, ponto B - próximo ao curtume, pontos C e D - localizados a jusante do curtume. Após 96 h de confinamento em gaiolas, foi realizada coleta de sangue e retirada dos tecidos dos animais e amostras de água e sedimento foram coletadas em todos os pontos. Os resultados mostraram maior concentração de cromo na água e sedimento do ponto B em comparação com o local sem influência do curtume, assim como maior acúmulo de cromo no fígado dos peixes expostos nesse ponto. Os animais expostos no ponto B apresentaram aumento na atividade da etoxiresorufina-O-deetilase (EROD) e da glutationa S-transferase (GST) e no conteúdo de glutationa (GSH) e proteínas semelhantes às metalotioneínas (PSMT). Esses resultados indicam maior contaminação deste ponto, decorrente do efluente líquido eliminado próximo a este local, causando alterações biológicas nos animais expostos. O segundo trabalho foi realizado com P. lineatus e S. notomelas submetidos a testes in situ, no verão, nos mesmos pontos do rio Bandeirantes do Norte e foram analisadas alterações nos mesmos biomarcadores. Com os resultados pode-se aplicar o Índice Integrado das Respostas dos Biomarcadores (IBR), para cada ponto. Foram observadas várias alterações nos biomarcadores analisados, nas duas espécies confinadas nos diferentes pontos. Os pontos localizados próximo ao curtume (B e C) foram os locais que apresentaram os maiores valores de IBR para as duas espécies. Assim, foi possível concluir que o efluente eliminado pelo curtume causa comprometimento da qualidade da água do rio Bandeirantes do Norte, com maior contaminação do ponto B, localizado logo após o curtume, resultando em alterações bioquímicas e acúmulo de cromo nos animais expostos esse ecossistema contaminado.
The industries of leather tanning eliminate large amount and diversity of contaminants in aquatic ecosystems and still have the problems arising from the use of chromium in the treatment of leather. Thus the objective of this study was the application of biochemical and genotoxic parameters of teleost Prochilodus lineatus and Serrapinnus notomelassubmitted to in situtests in order to assess the quality of Bandeirantes do Norte River (Rolândia - PR, Brazil), which receives effluents from a tannery. For that it was performed one work with juveniles of P. lineatus submitted to in situ tests in Bandeirantes do Norte River, during the winter,and biochemical and genotoxic biomarkers, chromium accumulation in fish tissues and the concentration of chromium in water and sediment were analyzed. The selected sites were: site A - upstream of the tannery, site B - near the tannery, sites C and D - downstream of the tannery. After 96 h of confinement in cages, blood collection and removal of tissues of animals was carried and water and sediment samples were collected at all sites. Chromium accumulation was determined in liver, kidney and muscle samples. The results showed higher concentrations of chromium in water and sediment from site B in comparison with the other sites and a higher accumulation of chromium in liver of fish caged at site B. Fish from site B showed an increase in activity of ethoxyresorufin-O-deethylase (EROD) and glutathione S-transferase (GST), content glutathione (GSH) andmetallothionein-like proteins (MT-like). These results indicate the higher contamination of site B, as the result of the input of liquid effluents in this location, causing biological changes in the exposed animals. A second study was performed with P. lineatus and S. notomelas submitted to in situ tests in the same sites as the other study, but during the summer, and changes in the same biochemical and genotoxic biomarkers were analyzed. The results obtained were used to calculate an index of integrated biomarkers responses (IBR) for each site. Several changes were observed in the biomarkers analyzed in the two fish species confined in different sites. For both species IBR values showed different patterns, indicating the points with higher contamination. The points near the tannery (B and C) were the sites that showed higher IBR for both species. Thus, it is concluded that the effluent eliminated by the tannery effluent causes the impairment of Bandeirantes do Norte River, with higher contamination at point B, located just past the tannery, resulting in biochemical changes and accumulation of chromium in animals exposed to this contaminated ecosystem.

The phonological acquisition considered normal happens when the language of the phonological system domain is spontaneously reached a common thread to most of the children within a certain age group of approximately 04 to 06 years, individual variations are evidenced in the construction of the phonological system. We proposed in this research investigation regarding the deletion / spelling production of coda for 7 students of the 3rd year of elementary school of a Municipal Public School in the city of Recife, from the chart record. The corpus will consist of written texts, observing the relationship between speech and spelling and interference that the written language learning process. The written testing instrument will be applied in order to observe to what extent is given the intervention of speech in writing regarding the deletion of syllable codas r, s, l in medial and final position of words, sentences and texts. We will focus on those records that alter the structure of the syllable, describing the way in which students record or not in its written coda position of syllables consisting of a consonant segment r, s, l. We start from the design based on the syllable syllable theory (SELKIRK, 1982), studies on syllable (HORA, 2006), theory of writing psychogenesis (FERREIRO; TEBEROSKY, 1999), (BORTONI-RICARDO, 2006), among others. As for the methodology, was classified as an experimental research of a qualitative nature, which initially made the collection of written words, containing the syllabic structure of coda filled by r, s, l, which was verified interference of speech in writing and in accordance with the observed errors, was initiated intervention with a didactic sequence with frequency of once a week for two months, using activities with phonological awareness. After completion of this was applied again to the same diagnosis made early in the process, in order to see if there was a change, improvement in students 'writing, where the data were analyzed and showed positive effects of the intervention on participants' performance.
A aquisição fonológica da escrita considerada normal ocorre quando o domínio do sistema fonológico da língua é alcançado espontaneamente em uma sequência comum à maior parte das crianças de uma determinada faixa etária, aproximadamente dos 4 aos 6 anos; variações individuais são evidenciadas na construção do sistema fonológico. A pesquisa se propôs a uma investigação a respeito do apagamento/produção da grafia da coda silábica por sete alunos do 3.º ano do Ensino Fundamental I de uma Escola Pública Municipal na cidade do Recife por meio do registro gráfico. O corpus foi constituído por textos escritos, observando-se a relação existente entre fala e grafia e a interferência daquela no processo de aprendizagem da língua escrita. O instrumento de testagem escrita foi aplicado com o intuito de observar em que medida se dá a intervenção da fala na escrita, com relação ao apagamento das codas silábicas r, s, l em posição medial e final de palavras, frases e textos. Foram focalizados aqueles registros que alteram a estrutura da sílaba, descrevendo o modo pelo qual os alunos registram ou não em sua escrita a posição de coda de sílabas constituídas de um segmento consonantal r, s, l. Partiu-se da concepção da sílaba fundamentada na teoria e estudos de Selkirk (1982 apud HORA 2006), teoria da psicogênese da escrita (FERREIRO; TEBEROSKY, 1991), variedade linguística trazida pelos alunos (BORTONI-RICARDO, 2006) dentre outros. Quanto à metodologia, classificou-se como pesquisa experimental, de natureza qualitativa, em que se realizou inicialmente a coleta de escrita de palavras, contendo a estrutura silábica de coda preenchida por r, s, l, na qual foi verificada a interferência da fala na escrita e, apagamento da coda silábica. Assim, de acordo com os erros observados, ou seja, desvios ortográficos em relação ao apagamento da coda silábica, a partir da diagnose feita inicialmente com os alunos, deu-se início à intervenção, através de uma sequência didática com periodicidade de uma vez por semana, durante dois meses, utilizando atividades com consciência fonológica, em que os dados foram analisados e mostraram efeitos positivos sobre o desempenho dos participantes.

[EN] Multiple-Input Multiple-Output (MIMO) technology in Digital Terrestrial Television (DTT) networks has the potential to increase the spectral efficiency and improve network coverage to cope with the competition of limited spectrum use (e.g., assignment of digital dividend and spectrum demands of mobile broadband), the appearance of new high data rate services (e.g., ultra-high definition TV - UHDTV), and the ubiquity of the content (e.g., fixed, portable, and mobile). It is widely recognised that MIMO can provide multiple benefits such as additional receive power due to array gain, higher resilience against signal outages due to spatial diversity, and higher data rates due to the spatial multiplexing gain of the MIMO channel. These benefits can be achieved without additional transmit power nor additional bandwidth, but normally come at the expense of a higher system complexity at the transmitter and receiver ends. The final system performance gains due to the use of MIMO directly depend on physical characteristics of the propagation environment such as spatial correlation, antenna orientation, and/or power imbalances experienced at the transmit aerials. Additionally, due to complexity constraints and finite-precision arithmetic at the receivers, it is crucial for the overall system performance to carefully design specific signal processing algorithms. This dissertation focuses on transmit and received signal processing for DTT systems using MIMO-BICM (Bit-Interleaved Coded Modulation) without feedback channel to the transmitter from the receiver terminals. At the transmitter side, this thesis presents investigations on MIMO precoding in DTT systems to overcome system degradations due to different channel conditions. At the receiver side, the focus is given on design and evaluation of practical MIMO-BICM receivers based on quantized information and its impact in both the in-chip memory size and system performance. These investigations are carried within the standardization process of DVB-NGH (Digital Video Broadcasting - Next Generation Handheld) the handheld evolution of DVB-T2 (Terrestrial - Second Generation), and ATSC 3.0 (Advanced Television Systems Committee - Third Generation), which incorporate MIMO-BICM as key technology to overcome the Shannon limit of single antenna communications. Nonetheless, this dissertation employs a generic approach in the design, analysis and evaluations, hence, the results and ideas can be applied to other wireless broadcast communication systems using MIMO-BICM.
[ES] La tecnología de múltiples entradas y múltiples salidas (MIMO) en redes de Televisión Digital Terrestre (TDT) tiene el potencial de incrementar la eficiencia espectral y mejorar la cobertura de red para afrontar las demandas de uso del escaso espectro electromagnético (e.g., designación del dividendo digital y la demanda de espectro por parte de las redes de comunicaciones móviles), la aparición de nuevos contenidos de alta tasa de datos (e.g., ultra-high definition TV - UHDTV) y la ubicuidad del contenido (e.g., fijo, portable y móvil). Es ampliamente reconocido que MIMO puede proporcionar múltiples beneficios como: potencia recibida adicional gracias a las ganancias de array, mayor robustez contra desvanecimientos de la señal gracias a la diversidad espacial y mayores tasas de transmisión gracias a la ganancia por multiplexado del canal MIMO. Estos beneficios se pueden conseguir sin incrementar la potencia transmitida ni el ancho de banda, pero normalmente se obtienen a expensas de una mayor complejidad del sistema tanto en el transmisor como en el receptor. Las ganancias de rendimiento finales debido al uso de MIMO dependen directamente de las características físicas del entorno de propagación como: la correlación entre los canales espaciales, la orientación de las antenas y/o los desbalances de potencia sufridos en las antenas transmisoras. Adicionalmente, debido a restricciones en la complejidad y aritmética de precisión finita en los receptores, es fundamental para el rendimiento global del sistema un diseño cuidadoso de algoritmos específicos de procesado de señal. Esta tesis doctoral se centra en el procesado de señal, tanto en el transmisor como en el receptor, para sistemas TDT que implementan MIMO-BICM (Bit-Interleaved Coded Modulation) sin canal de retorno hacia el transmisor desde los receptores. En el transmisor esta tesis presenta investigaciones en precoding MIMO en sistemas TDT para superar las degradaciones del sistema debidas a diferentes condiciones del canal. En el receptor se presta especial atención al diseño y evaluación de receptores prácticos MIMO-BICM basados en información cuantificada y a su impacto tanto en la memoria del chip como en el rendimiento del sistema. Estas investigaciones se llevan a cabo en el contexto de estandarización de DVB-NGH (Digital Video Broadcasting - Next Generation Handheld), la evolución portátil de DVB-T2 (Second Generation Terrestrial), y ATSC 3.0 (Advanced Television Systems Commitee - Third Generation) que incorporan MIMO-BICM como clave tecnológica para superar el límite de Shannon para comunicaciones con una única antena. No obstante, esta tesis doctoral emplea un método genérico tanto para el diseño, análisis y evaluación, por lo que los resultados e ideas pueden ser aplicados a otros sistemas de comunicación inalámbricos que empleen MIMO-BICM.
[CAT] La tecnologia de múltiples entrades i múltiples eixides (MIMO) en xarxes de Televisió Digital Terrestre (TDT) té el potencial d'incrementar l'eficiència espectral i millorar la cobertura de xarxa per a afrontar les demandes d'ús de l'escàs espectre electromagnètic (e.g., designació del dividend digital i la demanda d'espectre per part de les xarxes de comunicacions mòbils), l'aparició de nous continguts d'alta taxa de dades (e.g., ultra-high deffinition TV - UHDTV) i la ubiqüitat del contingut (e.g., fix, portàtil i mòbil). És àmpliament reconegut que MIMO pot proporcionar múltiples beneficis com: potència rebuda addicional gràcies als guanys de array, major robustesa contra esvaïments del senyal gràcies a la diversitat espacial i majors taxes de transmissió gràcies al guany per multiplexat del canal MIMO. Aquests beneficis es poden aconseguir sense incrementar la potència transmesa ni l'ample de banda, però normalment s'obtenen a costa d'una major complexitat del sistema tant en el transmissor com en el receptor. Els guanys de rendiment finals a causa de l'ús de MIMO depenen directament de les característiques físiques de l'entorn de propagació com: la correlació entre els canals espacials, l'orientació de les antenes, i/o els desequilibris de potència patits en les antenes transmissores. Addicionalment, a causa de restriccions en la complexitat i aritmètica de precisió finita en els receptors, és fonamental per al rendiment global del sistema un disseny acurat d'algorismes específics de processament de senyal. Aquesta tesi doctoral se centra en el processament de senyal tant en el transmissor com en el receptor per a sistemes TDT que implementen MIMO-BICM (Bit-Interleaved Coded Modulation) sense canal de tornada cap al transmissor des dels receptors. En el transmissor aquesta tesi presenta recerques en precoding MIMO en sistemes TDT per a superar les degradacions del sistema degudes a diferents condicions del canal. En el receptor es presta especial atenció al disseny i avaluació de receptors pràctics MIMO-BICM basats en informació quantificada i al seu impacte tant en la memòria del xip com en el rendiment del sistema. Aquestes recerques es duen a terme en el context d'estandardització de DVB-NGH (Digital Video Broadcasting - Next Generation Handheld), l'evolució portàtil de DVB-T2 (Second Generation Terrestrial), i ATSC 3.0 (Advanced Television Systems Commitee - Third Generation) que incorporen MIMO-BICM com a clau tecnològica per a superar el límit de Shannon per a comunicacions amb una única antena. No obstant açò, aquesta tesi doctoral empra un mètode genèric tant per al disseny, anàlisi i avaluació, per la qual cosa els resultats i idees poden ser aplicats a altres sistemes de comunicació sense fils que empren MIMO-BICM.

Third generation mobile communication systems promise a greater data rate and new services to the mobile subscribers. 3G systems support up to 2 Mbps of data rate to a fixed subscriber and 144 Kbps of data rate to a fully mobile subscriber. Code Division Multiple Access (CDMA) is the air interface access scheme widely used in all the 3G communication systems. This access scheme has many inherent advantages m terms of noise immunity, security, coherent combining of multi path signals etc. But all these advantages come at the expense of higher complexity of the receivers. The receivers form the major portion of the processing involved in a base station. The heart of any CDMA receiver is the RAKE. The RAKE receiver separates the different multi-paths received by the antenna by using the properties of the Pseudo Random sequences. The phase and strength of each of these path signals is measured and are used by the coherent combiner, which de-rotates all the signals to a single reference and coherently combines them In general the Base station receivers make use of the top three multi-path signals ranked in terms of their signal energy Hence four RAKE fingers, each catering to single multi-path are needed for receiving a single code channel (3 for coherent combining and one for scanning). One such channel receiver requires a processing power of 860 MIPS (Mega Instructions Per Second). Some of the CDMA standards support up to 90 code channels at the same time. This means that the total processing power required at the base station is about 80 GIPS. This much of processing power will require large number of high end DSPs, which will be a very costly solution. In the current base station architectures these blocks are implemented using ASICs, which are specific to a particular standard and also the algorithms used for the different operations are fixed at the design time itself. This solution is not flexible and is not amenable for SDR (Software defined Radio) architectures for the Base stations. This thesis proposes a Co-Processor solution, which can be attached to a generic DSP or any other processor. The processor can control the Co-Processor by programming its parameter registers using memory mapped register accesses. This co-processor implements only those blocks, which are compute intensive. This co-processor performs all chip-rate processing functions involved m a RAKE receiver. All the symbol-rate functions are implemented through software in the processor. This provides more choices m selecting the algorithms for timing recovery and scanning. The algorithms can be changed through software even after the base station is installed in the field. All the inputs and outputs of the Co-Processor are passed through dual port RAMs with independent read and write clocks. This allows the Co-Processor and the processor to be running on two independent clocks. This memory scheme also increases the throughput as the reads and writes to these memories can happen simultaneously. This thesis introduces a concept of incorporating programmable PN/Gold code generators as part of the Co-Processor, which significantly reduces the amount of memory required to store the Scrambling and Spreading codes. The polynomial lengths as well as the polynomials of the code generator are programmable. The input signal memory has a bus width equal to 4 times the bus width of the IQ signal bus width (4 * 24 = 96 bits) towards the Co-Processor to meet the huge data bandwidth requirement. This memory is arranged as word interleaved memory banks. This can supply one word per memory bank on each clock cycle as long as the accessed words fall in different memory banks. The number of banks is chosen as more than twice that of the number of Correlators/ Rake fingers. This gives more flexibility in choosing the address offsets to different Correlator inputs. This flexibility allows one to use different timing recovery schemes since the number of allowable address offsets for different Correlators is more. The overall complexity of the solution is comparatively less with respect to the generic DSP based solution and much easier to modify for a different standard, when compared to the rigid ASIC based solution. The proposed solution is significantly different from the conventional way of designing the Base station with fixed ASICs and it clearly outweighs the solutions based on conventional approach in terms of flexibility, design complexity, design time and cost.

This paper is divided into two major themes. One is a portable 9.4 / 18.8 GHz harmonic radar system using pulse pseudorandom code principle. The other is a bee searching radar with high transmit–receive isolation using pulse pseudorandom code. Harmonic radar is widely used to search the small insects. Because it can distinguish the reflection signals of transponders and surrounding objects. Since the 1990s, bees have been reduced by 17%-20% each year. To understand this phenomenon, this paper proposes a portable pseudo-random code harmonic radar system to search the bees’ bodies and provide this to the entomologist. This portable pseudo-random code harmonic radar uses the principle of pseudo-random codes to increase the sensitivity of the system and replaces the expensive computers and bulky oscilloscopes with analog circuits. This paper also proposes an innovative radar architecture to improve the isolation between the transmitter and receiver. The proposed radar system transmits two signals of similar frequency to the transponder, and the transponder responds a mixed signal to the receiver. Because the frequency of the mixed signal is different from the frequency of the surrounding reflected signals and the leakage signals, the isolation between the transmitter and the receiver can be greatly improved. For the harmonic radar, the leakage signals must be suppressed below -106 dBm to avoid affecting the sensitivity of the system. The proposed radar system only needs to suppress the power of the leakage signal to -8 dBm to avoid saturating the low-noise amplifier. In addition, the transponder of the harmonic radar can be used in the proposed system.

The New Zealand Food Bill is being passed amidst stern criticism of its content and the influence on it by multi-national corporations and the Codex Alimentarius Commission, whose food-safety standards motivated the bill. These concerns illustrate the large democratic and legitimisation deficits in global governance. One response to these criticisms and concerns is global administrative law, which focuses on promoting administrative law tools to enhance accountability. However, an examination of the Food Bill reinforces two main critiques of global administrative law: that it excludes addressing substance of international law and brackets democracy. I argue the limited GAL approach cannot be justified and the significant gaps in its approach require that it engage with democracy. I analyse the possibilities of global administrative law to engage with (to acknowledge and adopt) three theories of global democracy - deliberative, cosmopolitan, and radical pluralism. I argue deliberative democracy offers the most accessible option.

In this thesis, we consider using multiple transmit/receive antennas with orthogonal space-time coding (STC) in OFDM transmission system over frequency selective fading environment. Generally speaking, the space-time coding and associated diversity combining technique can provides a diversity gain of 2M by exploiting two transmit antennas and M receive antennas. In this thesis, we especially study two simple but most practical configurations is obtained for M=1 and 2, namely, the 2ISO and 2I2O STC-OFDM systems. It is shown that the STC-OFDM system ideally combines the major advantages of both techniques: It can not only offer robustness against large delay spread in high rate data transmission, but can also combat deep fading with a diversity gain of 2M. Furthermore, we consider the channel estimation/interpolation problem inherent to the STC-OFDM system. We first use pilot-symbol-assisted-modulation (PSAM) and the least squares (LS) approach to find the channel estimates at pilot subcarriers. Then we study three different channel interpolating methods : 1) Raised cosine interpolator, 2) FFT-based interpolator, and 3) Linear interpolator, for subsequent channel interpolation along the frequency axis. Finally, computer simulations are conducted to demonstrate and compare the performances of the STC-OFDM systems.

L’elaborato affronta la tematica del New Normal in Cina, inteso come il programma di riforme che la Repubblica Popolare Cinese ha predisposto per accompagnare la nuova fase di transizione, che vede il sistema-Paese abbandonare il vecchio paradigma della “Fabbrica del Mondo”, alla ricerca di un nuovo modello di sviluppo. Tale modello passa attraverso la ricollocazione verso l’alto dell’economa nazionale nella catena del valore globale ed una maggiore attenzione nei confronti degli aspetti maggiormente qualitativi della crescita economica, nonché di una accresciuta integrazione nell’economia mondiale, grazie ad una promozione dello stato di diritto e di un ambiente economico maggiormente trasparente ed aperto nei confronti degli operatori internazionali. Nell’analisi delle politiche e delle riforme che accompagnano questo cambiamento, svolta attraverso l’analisi di settori considerati strategici e particolarmente significativi (ambiente, sanità e food safety), la premessa alla base del lavoro è che tale transizione non è semplicemente descrivibile come mera convergenza verso un modello ricalcante i sistemi politici ed economici delle economie avanzate occidentali. La riforma è bensì intesa come un processo incrementale, che all’adozione delle cosiddette best practices internazionali affianca un approccio pragmatico, che non recede la linea di continuità con il background storico, politico, istituzionale e culturale -spesso contraddittorio- di quella che è considerata essere la più antica civiltà ortogenetica del mondo. Il contributo chiave del presente lavoro è la problematizzazione, nei suoi vari aspetti, di questa congiuntura storica e del suo portato nei confronti delle strategie di medio e lungo termine degli operatori economici stranieri che decidono di operare in Cina, i quali da un lato possono godere di grandi opportunità di mercato liberate dalle riforme, dall’altro devono essere consapevoli delle sfide inevitabilmente poste dal cangiante contesto giuridico, economico ed istituzionale e delle sue traiettorie di sviluppo.
