De, Angelis Silvia. "Algoritmi per la ricostruzione di immagini 3D di tomografia ad angoli limitati." Master's thesis, Alma Mater Studiorum - Università di Bologna, 2018.
Find full textAbstract:
La ricostruzione di immagini di tomografia ad angoli limitati può essere modellata tramite un sistema lineare, sottodeterminato a causa del numero limitato di proiezioni effettuate. Il problema viene quindi modellato come un problema di minimizzazione la cui funzione obiettivo è composta da due termini: la funzione Minimi Quadrati che rappresenta il fit con i dati e una funzione di regolarizzazione, Total Variation o Total p-Variation, che permette di sfruttare la sparsità del gradiente come informazione a priori.
In questo lavoro di tesi sono stati proposti due algoritmi iterativi di ricostruzione di immagini tridimensionali di tomografia ad angoli limitati: lo Chambolle-Pock e il Gradiente Proiettato Scalato.
Gli algoritmi stati testati su un problema test sintetico di medie dimensioni e poi applicati per la ricostruzione di immagini reali acquisite tramite un sistema di tomosintesi mammaria.
I risultati ottenuti sono molto promettenti, in quanto entrambi i metodi sono in grado di ricostruire molto accuratamente gli oggetti di interesse già dalle prime iterazioni, il che li rende realmente applicabili per la ricostruzione di immagini di tomosintesi in campo clinico, in cui si ha necessità di produrre le ricostruzioni in tempi molto brevi.

Find full textAbstract:
In questo studio si vogliono analizzare i diversi algoritmi proposti in letteratura necessari per la ricostruzione della cinematica articolare dell’arto superiore, analizzata tramite unità di misurazione inerziale wireless indossabili.
L’analisi quantitativa del movimento degli arti superiori del corpo umano può essere di grande utilità nella valutazione delle performance sportive, nella diagnostica, nel monitoraggio e nel trattamento riabilitativo di problemi articolari. Tuttavia, data la complessità dei movimenti consentiti dalle articolazioni degli arti superiori, solo recentemente, grazie allo sviluppo di nuove tecniche e tecnologie, la comunità scientifica ha iniziato a studiarne più nel dettaglio gli aspetti biomeccanici.
Negli ultimi anni lo sviluppo delle tecnologie MEMS, hanno portato alla produzione di dispositivi wireless inerziali/magnetici indossabili. Queste piattaforme multi-sensore si sono affermate nel mondo della Motion Capture poiché in grado di registrare ed elaborare in tempo reale i dati del movimento umano in modo del tutto non invasivo in ambienti quotidiani per periodi di tempo prolungati.
Per fare ciò è necessario utilizzare appositi algoritmi di sensor fusion che garantiscano l’accuratezza dei dati stimati a fronte dei numerosi errori che corrompono inevitabilmente le misurazioni effettuate dai singoli dispositivi integrati nelle piattaforme inerziali/magnetiche.
Le classi di algoritmi per la sensor fusion più comunemente utilizzate nell’analisi del movimento umano, e più in particolare nell’analisi degli angoli articolari degli arti superiori, sono: integrazione, osservazione vettoriale, filtraggio complementare e filtraggio di Kalman.

Bucchi, Anna. "Valutazione strumentale tramite sensori inerziali della validità dello squat nel Powerlifting." Bachelor's thesis, Alma Mater Studiorum - Università di Bologna, 2020.
Find full textAbstract:
Il Powerlifting è una disciplina internazionale in cui gli atleti si impegnano a sollevare un ammontare massimale di peso in tre diversi esercizi: lo squat, la distensione su panca e lo stacco da terra. Nonostante, in Italia, siano molte le persone che vorrebbero dedicarsi a questa disciplina non è sempre facile trovare un istruttore qualificato nella propria zona. Molti atleti, quindi, eseguono studi sull’argomento tramite libri o corsi online per poi svolgere gli allenamenti in autonomia, rendendo così complesso capire se gli esercizi che si stanno praticando sono eseguiti in maniera corretta. Attorno a queste problematiche si inserisce il presente lavoro di tesi, volto a fornire un’analisi della validità dello squat nel Powerlifting, tramite l’utilizzo di sensori inerziali. In particolare, è stato acquisito un soggetto (47kg, 158cm) con sensori inerziali e stereofotogrammetria, considerata strumento Gold Standard. Successivamente, i dati raccolti sono stati elaborati con diversi metodi e confrontati con l’approccio stereofotogrammetrico che considera per l’articolazione dell’anca il Grande Trocantere e per quella di ginocchio la porzione più prossimale della rotula (Protocollo PG-GT). Questo, allo scopo di valutare se i sensori inerziali sono in grado di stimare la validità dello squat commettendo un errore di al massimo 3°. Il metodo che considera la porzione più prossimale della rotula (PG) e la spina iliaca anteriore superiore (SIAS), consiste in un approccio che tende maggiormente a sovrastimare l’angolo della coscia rispetto alla verticale rispetto al metodo Gold Standard, utilizzare questo metodo nella pratica, in sostituzione all’approccio PG-GT, significa quindi valutare come valide un numero maggiore di prove. Gli algoritmi implementati che utilizzano i sensori inerziali non permettono di valutare la validità dello squat nel Powerlifting entro un errore massimo di 3°.

Rizqallah, Giada Jasmine. "Cinematica articolare del braccio destro durante l'esecuzione di una scala al violino." Bachelor's thesis, Alma Mater Studiorum - Università di Bologna, 2020.
Find full textAbstract:
Background e obiettivo: suonare uno strumento come il violino richiede competenze motorie elevate e molte ore di studio in posizioni scomode che possono portare, se ripetute sistematicamente e in maniera scorretta, all’insorgere di patologie e disordini muscolo-scheletrici. L’obiettivo di questo studio risulta essere l’identificazione delle differenze che si vengono a sviluppare tra musicista esperto e non; ci si concentra sulla parte dedicata al braccio destro e sulla tecnica d’arco con un ritmo imposto.
Metodi: il protocollo proposto sfrutta l’analisi cinematica ottenuta mediante stereofotogrammetria durante l’esecuzione di una scala al violino secondo due task differenti: prima a note sciolte e poi legate a coppie. Vengono misurati gli angoli di spalla, gomito, polso e archetto.
Risultati: gli inesperti si avvicinano all’esecuzione degli esperti con valori simili negli andamenti di FE di spalla e gomito, mentre la variabilità del polso rimane tendenzialmente più bassa e compensata dalle aperture maggiori di AA e IE di spalla. I soggetti mantengono l’arco tendenzialmente in asse come quello degli esperti e hanno basse fluttuazioni sul ritmo.
Conclusioni: misurazioni quantitative oltre che qualitative permettono un’analisi più approfondita sulla performance del musicista. Questo potrebbe rivelarsi utile sia in fase di studio per monitorare i progressi dello studente sia per sviluppi futuri sulla diagnosi di patologie legate ad un utilizzo scorretto e protratto nel tempo dello strumento.

Della, Corte Cesare. "Tecniche GPS/INS per l'anilisi dinamica di un ciclomotore." Bachelor's thesis, Alma Mater Studiorum - Università di Bologna, 2016.
Find full textAbstract:
Nel seguente elaborato si espone l’utilizzo del sistema GPS/INS per la valutazione del moto di un ciclomotore. Tale sistema è composto da sensori GPS ( Global Navigation System ) per la misurazione della posizione, e da sensori INS ( Inertial Navigation System) per la misurazione dell’accelerazione e delle velocità angolari rispetto a tre assi coordinati. Chiaramente le misure di accelerazioni e di velocità angolari da parte dei sensori, presentano dei minimi errori, che però si ripercuotono sul posizionamento finale. Per limitare questo fenomeno e rendere la misura di velocità e posizione utilizzabile, un filtro di Kalman viene impiegato per correggere il risultato dell'integrazione usando le misurazioni del GPS. Il connubio tra il sistema INS e il sistema GPS è molto efficacie anche quando si ha una assenza di ricezione satellitare o perdita parziale dei satelliti (cycle slip). Infine è stato utilizzato uno smartphone sfruttando i sensori in esso presenti : accelerometri, giroscopi, GPS, per analizzare la dinamica di un ciclomotore, concentrandosi sull’assetto in particolar modo l’angolo di rollio. Tale prova è stata affrontata non tanto per validare il sistema GPS/INS, ma per provare una soluzione comoda e di basso costo per analizzare il moto di un ciclomotore.

Full textAbstract:
L’obiettivo del presente elaborato è quello di verificare se la natura utilizzi determinati parametri di “design” nella progettazione dell’albero arterioso cerebrale per riuscire a mantenere un flusso sanguigno ottimale a tutte le regioni del cervello. L’attenzione è stata rivolta alle caratteristiche strutturali che una biforcazione del vaso sanguigno deve possedere. In questo lavoro di tesi si è cercato di verificare se le arterie del cervello e relative biforcazioni possiedono specifici requisiti strutturali, quali raggi e angoli di biforcazione, che permettano di seguire il principio di lavoro minimo. Dopo aver analizzato i calcoli teorici per determinare l’ottimizzazione parametrica ideale al fine di minimizzare la funzione costo secondo il modello di Murray, i risultati sono stati verificati dagli autori nella circolazione cerebrale, in particolare nell’arteria carotidea interna. Lo studio di Sandro Rossitti e Jan Lofgren ha dimostrato che nel processo di biforcazione del sistema arterioso carotideo esiste una relazione che lega il cubo del raggio delle arterie genitori alla somma dei cubi dei raggi delle successive arterie figlie. Si conferma dunque che il principio di lavoro minimo è rispettato e la funzione costo è minimizzata. Quest’ultima riguarda solamente i raggi dei vasi, in quanto gli angoli di biforcazione oscillano in modo non trascurabile attorno al loro valore teorico, perciò non contribuiscono all’ottimizzazione funzionale. Infine il meccanismo regolatore, che permette di mantenere un design ideale del vaso, risulta essere lo sforzo di taglio che agisce su ogni unità di area della parete del vaso sanguigno.

Full textAbstract:
Questa tesi nasce dalla collaborazione con la nazionale Italiana di Snowboard e ha come obiettivo fornire e valutare l’affidabilità di tre approcci per la stima della traiettoria del centro di massa degli atleti nello snowboard, utilizzando sensori inerziali indossabili. Le variabili da fornire agli atleti e agli allenatori sono state concordate e discusse con il direttore tecnico della Federazione Italiana Snowboard (FSI).
Nel primo capitolo saranno trattate le generalità della disciplina. Ad esse faranno seguito, nel secondo capitolo, la trattazione teorica dei principi di funzionamento dei sensori inerziali e la revisione della letteratura.
Nel terzo capitolo si descriveranno delle acquisizioni dei dati, sia in condizioni controllate, al fine di avere un valore di accuratezza, e successivamente sul campo.
Nel quarto capitolo saranno definiti gli algoritmi utilizzati nell’elaborazione, sia quelli appartenenti alle analisi temporali del gesto tecnico, all’analisi dei dati grezzi e della cinematica articolare, sia quelli relativi alla stima del centro di massa, seguendo sia la strada della ricerca della traiettoria in un sistema di riferimento globale, sia in uno relativo e solidale con l’atleta stesso, andando così a suddividere il problema con un approccio multiscala.
Applicando gli algoritmi sopra definiti, seguendo la stessa semantica del capitolo sulle acquisizioni, si descrive nel capitolo quinto l’elaborazione dei dati e nel sesto sono presentati i risultati. In particolare in quest’ultimo capitolo verrà fornita una risposta al problema iniziale in termini di possibilità di utilizzo della tecnologia dei sensori inerziali in studi outdoor di questo tipo e di quantificazione numerica dell’accuratezza legata all’utilizzo di questi metodi. Infine, nel settimo capitolo, sono esposte le conclusioni generali del lavoro e dei possibili sviluppi futuri.

Magister Legum - LLMThis thesis focuses on Foreign Direct Investment (FDI) in Angola and on constraints encountered by investors. It discusses the new Investment Law, resulting from a comprehensive law reform in 2003, as well as investment incentives destined to attract FDI into the territory, furthermore: the legal definitions of FDI and of “Investor”; the Angolan private international law; the main constraints (investment barriers) encountered by investors, after and before entering the Angolan territory; the legal protection afforded to investors, and some examples of FDI and their implications in Angola. The author also analyses investment and intra-trade within the Sub-Saharan region, Angola under modes 3 and 4 of GATS, and other aspects of foreign (as well as private) investment, including on what has been done and what should still be achieved under the SADC Trade, Finance and Investment Protocol from 2005 onwards. This analysis, it is hoped, will contribute to the better understanding of the implications and benefits of FDI in Angola, considering the recent increase of inflows of FDI, as well, as to what extent and how the Government should continue to control and direct, as well as encourage FDI. To conclude, the impact (positive -negative) of FDI in the Angolan society, economy and for the environment will be discussed. Together with the chapters describing the legal framework for FDI, these parts are intended to provide a better insight into the legal, economic and social background for investing and for doing business in Angola, and what type of protection investors can expect from the country, whilst information and academic materials on this subject matter continue to be scarce and difficult to access.

O presente trabalho tem como objetivo refletir sobre o processo de assimilação imposto às populações do território angolano dos anos de 1950 e 1960 presente na obra literária Kinaxixe, de Arnaldo Santos, publicada em 1965, em Portugal, e em 1981, no Brasil. A obra de nove contos retrata a tensa convivência dos negros, mestiços e brancos nos musseques e bairros que circundam a costa luandense no auge da maior migração de brancos portugueses ao território angolano. Por meio de leis como o então recente Estatuto do Indigenato, de 1954 e o Acto Colonial, de 1933 acirram-se as diferenças sociais. Esse plano jurídico foi baseado em teorias darwinistas do século XIX e lido de maneira hierarquizante e subjugadora, separando as populações do território angolano como não civilizados ou assimilados, e fazendo dos portugueses, em oposição, supostamente, civilizados, aptos a colonizar as populações do território baseado, por isso, na suposta superioridade cultural e social.This present paper aims to study the assimilation process imposed on the populations of the Angolan territory in the 1950s and in the 1960s seen in the literary work Kinaxixe, by Arnaldo Santos, published in Lisbon, Portugal in 1965 and in Brazil, in 1981. The nine short stories reflect the tense coexistence among black people, mixed race people and white people in the musseques (slums) and neighborhoods that surround the coast of Luanda. At this time, the largest Portuguese migration to the African territory took place. Through some laws such as the Estatuto do Indigenato, from 1954 and the Acto Colonial, from 1933, the social differences were even more stimulated. These legal spheres were based on Darwinist theories from the 19th century read in a patriarchal repressive and classicist way separating the populations in non-civilized or assimilated making the Portuguese, on the other hand, supposedly, civilized. Therefore, according to these thoughts, the Portuguese were prepared to colonize the Angolan population through, also a supposed, cultural and social superiority.

Dissertação de Mestrado em Finanças.O comércio internacional é uma temática que vem fazendo parte das grandes abordagens internacionais devido à sua relevância e tem contribuído para que, gradativamente, ao longo dos tempos se venham aprimorando os mecanismos que garantam uma eficaz relação entre os estados, bem como normalizando e regulando os assuntos inerentes às trocas comerciais entre os países. A Pesquisa teve como objetivo central descrever e avaliar os impactos da imposição de barreiras ao comércio e a aplicação de pautas aduaneiras nos fluxos de importações e exportações angolanas. Trata-se de uma investigação essencialmente qualitativa, do tipo exploratório e descritivo. Procedeu-se a uma análise documental, onde foram selecionadas as bibliografias relevantes para a construção e embasamento do referido estudo, onde foram recolhidas informações e dados em instituições oficiais angolanas. O estudo mostrou que as barreiras que podem conduzir ao incentivo da produção nacional são diversas, sendo as mais utilizadas as tarifárias e as não tarifárias, com maior relevância e aplicabilidade das segundas, tendo em atenção o cenário atual que o país vive, bem como a posição estratégica que o mesmo ocupa dentro do continente africano e da SADC (Southern African Development Community) da qual o mesmo é membro integrante. A Pauta Aduaneira Angolana sendo um documento oficial aprovado através de um Decreto Legislativo Presidencial nº 10/13 de 22 de Novembro, e concebido de acordo as premissas do GATT (General Agreement on Tariffs and Trade), ou seja, o Acordo Geral sobre Tarifas e Comércio da OMC e do Sistema Harmonizado, permite ao Estado angolano conceder a isenção no pagamento de mercadorias de interesse Governamental e que ajudam nos processos de revitalização e dinamização do setor industrial. Para que tal facto ocorra, as medidas Governamentais em torno do controlo do comércio internacional e que alavancam o processo de industrialização de Angola, não podem ser aplicadas isoladamente pois não são suficientemente eficazes para alterar o atual quadro socioeconómico de Angola. No entanto, elas devem ser aplicadas em paralelo ou em bloco, respectivamente com o processo de subvenção pelo Estado Angolano nos setores primário e secundário da Economia, garantindo desta forma as premissas necessárias para a alavancagem e sua solidificação.
International trade is a theme that has been part of international approaches due to its importance and has gradually and over time driven to upgrade mechanisms that ensure an effective relationship among the states, as well as the regulation of businesses between countries. This research main objective was to describe and assess the impact of the imposition of trade barriers and the application of tariffs to Angolan imports and exports. This research is mainly qualitative, with a descriptive and exploratory focus. A documentary analysis was made and the most relevant bibliographies were selected for the construction of this study together with data collected from Angolan official institutions. The study showed that various barriers may drive to domestic production encouragement, being the most commonly used tariff and non-tariff barriers, with greater relevance and applicability of the later, taking into account the current scenario and strategic position that Angola ranks, within SADC and the African continent of which it is an integral member. The Angolan Customs Tariff being an official document approved by Decree Law No. 2/08 dated August 4 and designed according the assumptions of GATT (General Agreement on Tariffs and Trade) and the Harmonized System, allows the Angolan State to grant an exemption in payment of goods of Government interest and help in the revitalization and promotion of the industrial sector. For such event to occur the Government measures related to the control of International Trade which boost the industrialization process of Angola, can not be separately applied, seeing that they are not effective enough to change the current socio-economic context of Angola. However, they should be applied in parallel or in block, respectively with the grant process by the Angolan Government in the primary and secondary sectors of the economy, thus ensuring the necessary assumption for leverage and its solidification.

A história recente de Angola é disso um exemplo eloquente. A sustentação da guerra civil de que o país foi palco, muito se deveu a disputas geopolíticas no quadro da Guerra Fria. Neste trabalho abordamos o Conceito Estratégico Nacional (CEN) e a sua aplicação ao caso angolano. A análise abrange o período de 2002, que marca o fim do conflito ao ano de 2017. Com recurso a análise de documentos emitidos pelo Estado angolano e de entidades com interesse em apresentar visões programáticas sobre o país, foi-nos possível com base na identificação dos Interesses nacionais (IN) e os Objectivos nacionais (ON) que preconizam e o alinhamento destes com as Aspirações nacionais (AN), inferir sobre o CEN no caso angolano. Concluímos que não se afigura a existência de um CEN no período em análise, no entanto, mostra-se possível a concepção e implementação de um CEN no caso de Angola.
Angola raises interests and geopolitical disputes due to its strategic potential, which has to do with its geographical location and its abundance in strategic resources. Those interests and disputes can only be overcome and taken advantage of by setting up competent and dynamic organizational structures which depends on an active geopolitical awareness. The recent period of Angolan history it is a great example of that. The support and sustenance of the civil war which eroded the country was due to geopolitical disputes in the framework of the Cold War. In this study we assess the applicability of National Strategic Concept to the Angolan case. The analysis covers the period from 2002, which marks the end of the conflict to the year 2017. Based on the analysis of documents issued by the Angolan State and entities interested in presenting programmatic visions about the country, we were able by identifying the Interests and goals that they advocate and their alignment with the national Aspirations to infer about a National Strategic Concept for the Angolan case. We concluded that there are not elements that may account for a National Strategic Concept in Angola on the period under review, however, it is possible to design and implement one.

Expressões como "bater na rocha", "tirar voado", "sukula zuata", "mãe grande", entre outras, foram estudadas à luz da literatura especializada da área da Fraseologia. O estudo baseou-se numa amostra prévia, constituída propositadamente para este efeito, e pelos dados recolhidos por meio de um inquérito que foi realizado junto de 242 falantes angolanos (entre os 14 e os 70 anos) de ambos os sexos, bem como recolhidos em jornais, letras de músicas e alguns programas televisivos, o que permitiu proceder ao cruzamento desses dados e aferir a generalização das EIs quanto ao seu uso.
Além da análise das EIs que constituem o corpus do trabalho, procurou-se igualmente analisar a consciência linguística dos falantes a respeito dessas expressões.
Em resumo, com esta dissertação procura-se contribuir para os estudos da fraseologia do Português de Angola, domínio ainda escassamente investigado; Abstract:
Contributions to the study of idiomatic expressions in Angolan Portuguese
Angola is a multilingual country with a great ethnic and cultural diversity, which explains the existence of the Angolan variety of Portuguese own characteristics. These are due not only to the above-mentioned diversity but also to the specific conditions for the acquisition of that language in Angolan territory and, of course, to the influences/interference of national languages, even among speakers who only have Portuguese as their mother tongue. The main purpose of this dissertation is to study one of the aspects in which Portuguese spoken in Angola manifests the influence of national languages: phraseology. Thus, the specific objective is to analyze a sample of the Angolan phraseology, that is, of the idiomatic expressions (IE) used in Angolan Portuguese. Expressions as "bater na rocha", "tirar voado", "sukula zuata", "mãe grande", among others, were studied according to the specialized literature in the Phraseology field. The study was based on a previous sample, purposely constituted for this purpose, and on the data collected through a survey that was carried out among 242 Angolan speakers (between 14 and 70 years old) of both genders as well as collected in newspapers, lyrics and some television programs, which allowed us to cross these data and assess the generalization of IE regarding their use.
In addition to the analysis of the IE that constitute the corpus of the work, it was also aimed to analyze the linguistic awareness of the speakers regarding these expressions.
In short, this dissertation seeks to contribute to the studies of the phraseology of the Portuguese of Angola, still a poorly domain researched.

Os fluxos migratórios, num contexto de globalização, é um fenômeno da contemporaneidade e entendê-lo, a partir da memória e da história de vida dos sujeitos que viveram e vivem esse processo, é permitir a escrita de uma história que ainda não está registrada. O presente trabalho é o resultado da pesquisa sobre o deslocamento de imigrantes angolanos para a cidade de São Paulo, ocorrido nas primeiras décadas do século XXI. Por meio da História Oral, registramos histórias de vida desses sujeitos para compreender como experimentaram a vivência de sair de seu país, a chegada ao Brasil, os dilemas de pertencimento na sociedade de destino, a reconfiguração e ressignificação dos espaços e das relações cotidianas nesse novo contexto.The migration, in the context of globalization, is a phenomenon of contemporaneity and understand it from the memory and history of life of individuals, who have lived and live this process is to allow writing a story that is not yet registered. This work is the result of research on the displacement of Angolan immigrants to the city of São Paulo, which occurred in the first decades of the twenty-first century. Through oral history, we recorded the life histories of these subjects to understand how they experience the leaving their country, the arrival in Brazil, the dilemmas of belonging in the society of destination, reconfiguration and redefinition of spaces and everyday relations in this new context.

Dans notre travail nous voulons démontrer que, la guerre et la pauvreté n'auraient pas contribué à la baisse de la fécondité au sein d'une population déplacée, ancrée dans la tradition et le culte des ancêtres. Rompre avec cette tradition sans toutefois offrir des alternatives c'est nier son passé et sa culture. Les hommes et les femmes africains accordent beaucoup d'importance aux enfants pour assurer la continuité de lignée. Les données de notre enquête montrent que les femmes déplacées de guerre à Luanda ont une parité moyenne plus élevée que les femmes autochtones. Cette différence s'explique à travers les inégalités d'accès aux méthodes contraceptives modernes. Cependant, il est prouvé qu'il existe une relation entre la maîtrise de la fécondité et la pratique contraceptive. En milieu urbain, plusieurs facteurs contribuent à la baisse de la fécondité entre autre l'âge de la femme au mariage, l'instruction, la situation professionnelle. . . . Mais les difficultés pour entretenir une famille nombreuse peuvent obliger à réduire les naissances sous l'impact d'un "malthusianisme de pauvreté".

Les risques des décharges électrostatiques (DES) sur des dispositifs et systèmes électroniques dépend de l'état de charge de l'opérateur et des objets situés à proximité. Cette thèse a eu comme objectif de contribuer à la mise au point d'une méthodologie de mesure pour caractériser l'état de charge des opérateurs et des matériaux textiles, afin d'établir leur capacité de produire DES nuisibles. Des méthodes de mesure directes et indirectes ont été proposées pour l'évaluation de la charge des opérateurs dans trois situations d'intérêt pratique. D'autres techniques, telles que la mesure de potentiel de surface et de l'intensité du champ électrique ont été utilisées pour le monitoring de l'état de charge des matériaux textiles. Des modèles comportementaux ont été établis pour la charge et la décharge de ces matériaux, en faisant appel à la méthodologie des plans d'expériences. Les essais réalisés sur des échantillons de polypropylène et de polyester ont permis de valider aussi deux méthodes permettant d'accélérer la diminution de la charge des médias isolants non-tissés en utilisant des générateurs d'ions ou des décharges couronne produites par des électrodes alimentées à des hautes tensions sinusoïdales ou triangulaires, de fréquences allant jusqu’à 400 Hz. Un exemple d'accumulation d'électricité statique sur une plaquette de silicium est aussi discuté, en rapport avec une application à la fabrication des microsystèmes électromécaniques. L'amélioration de la méthodologie de mesure est un pré-requis pour l'adoption des meilleures stratégies destinées à maîtriser les risques électrostatiques dans un environnement industrielThe risk of electrostatic discharge (ESD) on electronic devices and systems depends on the charge state of the operator and nearby objects. This thesis aimed at contributing to the development of a measurement methodology to characterize the state of charge of the operators and textile materials, in order to determine their ability to produce harmful effects. Direct and indirect measuring methods have been proposed for assessing the charge of operators in three situations of practical interest. Other techniques, such as surface potential and electric field intensity measurements were used for monitoring the state of charge of textile materials. Behavioural models have been established for the charging and discharging of these materials, using the methodology of experimental design. Tests on samples of polypropylene and polyester have also validated two methods for accelerating the reduction of the charge of insulating nonwoven media using ion generators or corona discharge produced by electrodes energized from sinusoidal or triangular high voltage supplies, at frequencies up to 400 Hz. An example of static electricity on a silicon wafer is also discussed in relation with an application to the fabrication of mechanical and electronic micro-systems. Refinement of the measurement methodology is a prerequisite for the adoption of best strategies to control electrostatic risks in an industrial environment

Full textAbstract:
The blacktail, Diplodus capensis, is an inshore sparid fish distributed from Mozambique to Angola. This species forms an important component of coastal fisheries within its distribution, one being the subsistence handline fishery in southern Angola. With this fishery being critically important to the livelihoods of local communities, a biological study and stock assessment was conducted to provide information for the management of this species in southern Angola. However, with molecular evidence suggesting that the Benguela current may have separated the southern African populations of many inshore fish species over two million years ago, a morphological, taxonomic analysis was considered necessary to first investigate whether there was evidence for allopatry in this species. A total of 46 morphometric measurements and 18 counts were carried out on specimens collected from various locations in southern Angola and South Africa. Results were analysed using multi-dimensional scaling (MDS) and the significance of clusters was tested using analysis of similarities (ANOSIM). Biological samples of D. capensis were collected monthly from an unexploited area from April 2008 to March 2009. Additional biological samples were collected from the subsistence fishers in an exploited area during May, June and December 2009. Standard biological laboratory techniques were employed for the lifehistory comparison between the exploited and unexploited area. A per-recruit analysis was conducted using the life-history parameters from both areas in order to assess the current status of the subsistence fishery and to investigate the potential short-falls of the per-recruit assessment approach. The morphometric comparison showed that there was not sufficient evidence for speciation between the southern Angolan and South African populations of D. capensis. There was, however, sufficient morphological evidence to suggest that these populations are separate stocks. This indicated that the existing reference points on which the management of the South African population is based are unsuitable for the Angolan population. Diplodus capensis in southern Angola is omnivorous, feeding predominantly on algae, barnacles and mussels. An ontogenetic shift from algae to barnacles and mussels was correlated with allometric growth patterns in their feeding apparatus. This species is a rudimentary hermaphrodite in southern Angola with peak spawning in June and July. The overall sex ratio (M: F) was 1: 4.7 in the unexploited area and 50% maturity was attained at 149.5mm FL and five years. Diplodus capensis in southern Angola exhibits very slow growth with the maximum age observed being 31 years (validated using mark recapture of chemically injected fish). Females [L(t) = 419.5(1-e⁻°·°⁴⁵⁽t⁻³·⁴ ⁾)] grew significantly faster (LRT, p < 0.05) than males [L(t) = 297.4(1-e⁻°·°⁷⁷⁽t⁻²·⁷⁾)], and females dominated the larger size classes and older age classes. In the exploited area, the length and age frequencies were severely truncated, the maximum observed age was greatly reduced (17 years) and the sex ratio was less female biased at 1: 2.2. Although there was no evidence for a physiological response to exploitation through alterations in growth or size/age at sexual maturity between the two areas, there was an increase in the proportion of small females in the exploited area, which may have been a compensatory response for the loss of large females. A combination of an underestimate of longevity, different estimates of the Von Bertalanffy growth parameters and overestimates of the natural mortality rate in the exploited population resulted in a 92% underestimate of the pristine spawner biomass-per-recruit (SBR) value. An assessment based on the actual pristine SBR estimate from the unexploited area revealed that the subsistence fishery had actually reduced D. capensis to 20% of its pristine SBR levels and highlighted the value of pre-exploitation life-history information for the application of per-recruit models. This study has shown that D. capensis in southern Angola displays life-history characteristics that render it susceptible to overexploitation, even at low levels of fishing pressure. The current lack of infrastructure and enforcement capacity in the fisheries department of Angola renders traditional linefish regulatory tools, such as size limits, bag limits and closed seasons, inappropriate. Therefore, suitably designed marine protected areas are recommended as the best management option for this species.

As mulheres no decorrer da história passam a assumir tarefas que diferem do ambiente familiar e doméstico por conta das mudanças na sociedade e que possuem características similares e diversas na busca por um lugar no mercado de trabalho.
O empreendedorismo feminino está em evidência, por conta do processo de feminização do mercado de trabalho, e ocorre assim um aumento gradativo de empreendimentos organizados por mulheres, tornando-se cada vez mais importante conhecer as razões que levam a mulher angolana a empreender e ainda revelar uma parcela das particularidades do empreendedorismo feminino, destacando a trajetória da mulher no mercado de trabalho, setores de empreendimento, gestão feminina e consequências para a sociedade, segmentando por necessidade e/ou oportunidade.
O presente estudo não foi conduzido apenas por proposições e obras que remetem os conceitos apresentados, mas por meio de uma pesquisa qualitativa com mulheres que já se consolidaram como empreendedoras e outras que ainda estão à caminho. Pelo seu caráter exploratório, a pesquisa qualitativa levou as entrevistadas a refletirem sobre o tema em estudo revelando assim, aspectos subjetivos que fazem parte das suas ações empreendedoras. Este estudo teve como principal objetivo examinar de maneira minuciosa percepções acerca da natureza das motivações, significados e desdobramentos da iniciativa feminina, por isso, a abordagem qualitativa foi a escolhida para este trabalho por ser a que melhor fornece condições de explorar o fenómeno do empreendedorismo feminino.Throughout the history of their lives women assume tasks that differ from the domestic and family environment due to changes in the society, and posess characteristics similar and diverse in the search for a place in the labor market. Feminine Entrepreneurship is an evidence, due to the feminization process of the labor market, and so it occurs a gradual increase of businesses established by women, becoming even more important to know the reason that lead Angolan women to invest and reveal a percentage of the particularities of the feminine entrepreneurship, defining the trajectory of women in the labor market , entrepreneurship sectors, feminine management and consequences to the society, segmented due to necessity or opportunity. This study was not conducted only by propositions and works that recall the concepts presented, but through a qualitative research with women who have consolidated as entrepreneurs and others that are still on the way. For its exploratory nature, the qualitative research led the interviewees to reflect about the subject under study revealing subjective aspects that are part of their entrepreneurial activities. This study aimed to examine in detail perceptions about the nature of the motivations, meanings and consequences of women's initiative, therefore, the qualitative approach was chosen for this work because it is the one that best allows to explore the phenomenon of female entrepreneurship.

Over the last decade and the rise of the PRC, the Sino-African relations evolved from political to economic. As the Chinese economic interests in Africa strongly developed, this paper explains how China managed to become a preeminent development partner in the Sub-Saharan Africa and the repercussions of this enclosed cooperation. Hence, it examines the Chinese strategy to gain entry into these countries and the repercussions it had on different layers of the local economies. The findings show that China heavily invested and granted large loans with advantageous repayment conditions paired with minimal obligations for money delivery. As a result, China had access to natural resources in exchange for financing and operating infrastructure development. The immediate effect for African nations has been the explosion of capital accumulation gathered through international market. These enhanced capital increase had repercussions on the nations’ immediate economic growth; Angola having been the world’s fastest developing country over the first decade of the years 2000’s. However, to be competitive against the IMF’s development program, the lowly conditioned Angola Mode found a break in the output diversification and the non-systematic economic development. As such, it appears that the Angola Model’s blueprint and its non-interference in local administration is a formidable opportunity to gather capital and develop communication systems for a nation committed to growth and development but it would rather appear as meaningless in case of funds misallocation. Following these highlighted pros and cons, this dissertation is concluded with a set of policy recommendations oriented for both African nations’ long term development and the improvement of the current Angola Model to achieve a greater efficiency.published_or_final_version

Além de resultar num conhecimento melhor do clima regional, esses estudos permitem um prognóstico ou antevisão do clima futuro, de extrema importância para se gerirem os recursos naturais e hídricos e para o planeamento das actividades humanas.
Neste trabalho, analisaram-se séries temporais de precipitação de longo prazo, existentes para várias localidades de Angola, verificando sua consistência espacial, ciclos aparentes e suas tendências. A precipitação regional foi relacionada com fenómenos atmosféricos de alta-frequência, como eventos El Nino e La Nina e com fenómenos de baixa frequência, como a Oscilação Decadal do Pacífico (ODP). Um exercício complementar foi realizado ao se correlacionarem os dados de precipitação com o conjunto de dados de Reanálises do NCEP para verificar possíveis divergências relativamente aos dados observados, validar esses conjuntos de dados para sua utilização em modelos regionais que usam técnicas de "downscaling" estatístico ou dinâmico.

Full textAbstract:
Cette thèse est divisée en deux parties, d'une part, pouvoir politique et organisation sociale chez les Bakongo entre tradition et modernité et d'autre part, organisation religieuse, politique et sociale et spectre des alliances et s'articule autour de sept chapitres. Il s'agit du cheminement du pouvoir politique et de l'organisation sociale chez les Bakongo de l'Angola à travers de nombreux indicateurs, continuité, transition et transformation dues à la fois à l'impact des contacts avec les anciennes puissances coloniales européennes et à une mondialisation de plus en plus croissante. Nous sommes partis de l'hypothèse de la conception et pratique traditionnelle et moderne de l'organisation du pouvoir politique comme lieu d'intersection des organisations sociales impliquées dans les stratégies d'alliances à travers leurs Leaders politiques respectifs en référence à leurs appartenances ou origines sociales respectives. Le spectre d'alliances présent dans notre travail sous forme d'une typologie et non uniquement un procédé classificatoire, est façonné par des rapports matrimoniaux, en ce sens que les rapports de mariage entre deux être appartenant à deux groupes sociaux distincts deviennent un élément de stabilité de l'exercice ou de la pratique du pouvoir politique et des rapports contractuels entre les groupes sociaux, religieux, ou partis politiques. Entre l'Organisation sociale et l'organisation politique, la religion principalement le messianisme peut être analyser en terme de médiationThis thesis is divided into two parts : the first part concentrates on the evolution of political power and social structure amongst the Bakongo people and the second part discusses religious, political and social structure and the different alliances found in this society. Thse themes will be explored over seven chapters. The thesis concerns the progression of the political power and social structure of the Bakongo people of Angola through several different indicators : continuity, transition and transformation, due both to the impact of European colonisation and to the ever-increasing effects of globalisation. We took as our starting point the model of the traditional and modern political conceptions and practices as a point of intersection for social groups involved in alliance tactics between their political leaders, with regard to their respective backgrounds or social origins. The sectrum of alliances present in our study in the form ot typology (and not only of a classifying process), is shaped by matrimonial associations, in the sense that the ties of marriage between two people pertaining to two distinct social groups impose an element of stability in the exercice and practice of political power and the contractual links between social and religious groups or political parties. Between social organisation and the political organisation, the religion principally the messianism may be analysis in term of mediation

Full textAbstract:
The field of angelology is vast. This thesis investigates the artistic representations of angels from the Late Middle Ages through the Reformation, from c.1450 to c.1650. This is achieved by a careful selection of material which demonstrates how the angelic form mutated in response to the religious and political changes experienced in England during this time. Thus, attention has been focussed on three main areas that form the components of this study: Chapter one investigates the integral role that angels played in the late-medieval Catholic belief system, drawing on primary and secondary literature to demonstrate how scholars viewed angels and specifically, how they categorised and differentiated the various orders of angels. Chapter two examines four case studies of representations of the angelic hierarchy at a local and national level, in different media, in order to evaluate how the doctrine surveyed in chapter one was manifested in artistic practice, with special attention to how angels were depicted on the eve of the Reformation. Chapter three examines the Reformation in terms of angelology, with particular regard to the European and English reformers’ views on the artistic representation of these celestial creatures, from the beginnings of religious change to the era of the Commonwealth. The hypothesis that angels were not represented on tomb monuments in the Elizabethan period is tested, by investigating the counties of Leicestershire and Rutland, looking at the monuments of the period c. 1550-c.1650. This chapter also addresses how the English responded to the call of the iconoclasts and investigates whether angels were treated in the same conceptual and ideological category as the saints, or if they managed to survive. I shall contend that despite the changes to Christianity in England, during the period of concern for this study, angels continued to be part of the faith as demonstrated by their continued portrayal in art and sculpture.

Full textAbstract:
This thesis provides a new analysis of late medieval personal devotion to angels in England, built upon freshly compiled primary evidence. This evidence consists of devotional material collected from a large sample of fifteenth-century Latin manuscript Books of Hours either produced in England or produced elsewhere for the English market. The use of a properly constructed sample of manuscripts in this research has provided a large and varied body of material for analysis. It has also revealed trends and patterns stemming from a clear context, relevant to both the material and to the Books of Hours containing it, across a significant number of manuscripts. Whilst angels feature in all Books of Hours, often in support of devotion to other figures, the emphasis of this thesis has been analysis of the material in which the angels themselves are the main focus of devotion. These 'angelic' texts and illuminations are important because they represent the choices and preferences of individuals, both lay and religious, concerning the contents of their Books of Hours. The main body of the thesis is an analysis of this textual and visual evidence and of its manuscript settings, which leads into fresh devotional perspectives and findings. These relate to both those who composed or produced the materials and those who used them in their Books of Hours. Analysis also leads to the suggestion of new hypotheses concerning the surprising range of sources which was drawn upon in creating specialised and erudite texts.

Les sujets représentés sont "naturalistes" (site no 1), géométriques avec prédominance de cercles (sites no 7,8,9) ou bien des sites "mixtes" avec des sujets "naturalistes" et abstraits conjugués (région sud-ouest) la chronologie de l'art pariétal n'est pas encore établie avec précision. Néanmoins des indices comme la présence des objets européens et des datations 14c permettent d'élaborer une tentative de chronologie relative. Des datations ams 14c permettent d'affirmer qu'au moins un site du sud-ouest aurait 2000 ans d'ancienneté. L'interprétation des œuvres peintes ou gravées est complexe. L'existence des sujets, actuels, graves, peints, ou dessines sur le sable, dont une signification est connue permet d'avancer des hypothèses sur l'éventuelle signification de certaines figures ou situations de ces vestiges du passé de l’Angola.

Etude grammaticale de l'iwoyo, langue bantoue angolaise appartenant au sous goupe "kikongo", parlee au cabinda et classe par m. Guthrie dans la zone h16a. Ce travail, realise conformement au cadre theorique et methodologique utilisee par e. Bonvini pour lalangue kasim, est precede d'une introduction generale et articule en quatre chapitres. Le premier a ete consacre a la morphosyntaxe de la predication ou sont degages les schemas des enonces de l'assertion, de l'interrogation et de l'intimation. Il a ete par la suite possible d'identifier deux grandes categries de constituants syntaxiques : le nominal et le verbal. Le deuxieme chapitre traite du nominal. En utilisant d'une maniere conjointe les notions de "classe" et de "genre", nous avons pu ensuite analyser son comportement en tant que constituant syntaxique plurifonctionnel. 18 classes et 13 genres ont ete identifies. L'analyse s'est poursuivie avec l'etude du nom, du syntagme nominal, du pronom et du numeral. Le troisieme chapitre presente le systeme verbal sur la base de la distinction entre le constituant verbal lui meme et les specificatifs verbaux. Le quatrieme chapitre est consacre a l'etude de l'enonce et de ses variations internes et externes. Les premieres concernent la focalisation et la thematisation tandis que les secondes se referent a la coordination et a la thematisationThe goal of this work is to give a clear inderstanding of the grammacial structures of iwoyo, an angolan bantu language spoken in cabinda and classified by m. Guthrie under the h16a zone. After an introductory background concerning some basic geographical informations about the country, and a brief geographical and historical description of cabinda the first chapter present the structures of the major utterances attested by the language: assertive, interrogative and intimative sentences which provided the inventory of the nominal and verbal constituents. The second chapter deals with the nominal constituent analyzed through two methodological frameworks: bantu traditional one and e. Bonvini's. We first discussed class systeme and gender marlers; then we studied successively the noun, the noun phrase, the rponoun and the numeral. In the third chapter the verbal constituent is analyzed in detail. Through considering bantu traditional methode, we made a distinction between the verb and its specifiers, accordingly to e. Bonvini's suggestion. In the last chapter we studied the internal and external enunciative variations, specially topicalizationin one hand and corrdination and subordination on the other

Full textAbstract:
L "étude grammaticale du kimbundu" comporte quatre chapitres : énonciation et prédication, le verbal, le nominal et l’énonce et ses variations. Dans le premier chapitre, "énonciation et prédication", l’organisation morphosyntaxique de la langue a dégagé tout particulièrement les schèmes prédicatifs propres à l’assertion, l’intimation et l’interrogation. Elle a également dégagé deux catégories formelles de la langue : le nominal et le verbal. Le deuxième chapitre, "le nominal », etudié sur quatre formes : le nom, le syntagme, le pronom et le numéral. Le nom se présente comme une séquence du type nominant + base. C’est le nominant qui confère a la base le statut de du sujet. La base est précédée par la marque de temps ou de mode (t m) et suivie par le verbant dont sa valeur sémantique est celle d’aspect. C’est le verbant qui confère à la base le statut de constituant verbal. Le quatrième chapitre, "l’énoncé et ses variations", ce n’est qu’une amorce d’une approche de ce domaine.

Full textAbstract:
Cette thèse porte sur l'étude du système grammatical du Kisikongo, dialecte du kikongo (langue bantoue, h10), parle au nord-ouest de l’Angola. S’inspirant de la méthode d'E. Bonvini, l'analyse porte principalement sur la morphosyntaxe de la prédication, le nominal, le verbal et l'énoncé et ses variations. Le premier chapitre présente l'inventaire des schèmes d'énoncés verbaux (assertifs, intimatifs et interrogatifs) et nominaux et identifie le schème prédicatif sous-jacent a tous les énonces de la langue, ainsi que les fonctions syntaxiques et les constituants qui les assument. Le deuxième chapitre étudie d'abord le nominant en tant que morphème majeur commun à tous les nominaux et organise en un système basé sur une double réalité : celle de "classe" et de "genre". Il se poursuit par l'analyse détaillée du nom (simple et compose), du pronom, du numéral et du syntagme nominal. Le troisième chapitre présente d'abord une systématique formelle des éléments de la forme verbale selon la méthode des bantouistes. Il étudie ensuite le verbal a deux niveaux : au niveau du constituant verbal, l'étude porte sur le dérivatif verbal en tant qu'élargissement formel et sémantique de la base verbale et support de la diathèse verbale, ainsi que le verbant, en tant que morphème aspecto-temporel. Au niveau de la spécification verbale sont analyses les actualisateurs, les indices de fonction ainsi que les spécificités verbaux. Enfin, le quatrième chapitre traite des variations énonciatives internes (focalisation et thématisassions) et des variations énonciatives externes liées à la séquence des propositions (coordination et subordination)This thesis presents a study of the grammatical system of Kisikongo, a Kikongo dialect (h10) spoken in north-western Angola. Based on the E. Bonvini's methodological framework, it is carried out into four chapters : the first one makes an inventory of the verbal (assertive, intimative and interrogative) and nominal schemes of utterances, establishes the underlying sentence structure common to all Kisikongo utterances and identifies the major syntactic functions and constituents. The second chapter is devoted to the nominal. It first discusses the system of class and gender markers and goes on studying the simple and compound noun, the pronoun, the numeral and the noun phrase. The third chapter provides a detailed analysis of the verbal. It first analyses the formal elements of the verb form following the bantuist methodological framework. It then considers the verb stem, the derivational process, including verbal diathesis and the aspecto-temporal morphemes. In the last section the verbal specifiers are analyzed : pronominal prefixes, negation operators, ad-verbs and auxiliaries. Finally, the fourth chapter treats of the internal variations (topicalization) and the external ones (complex sentence structure, including relatization)

Full textAbstract:
This study examined the main strategies adopted by the Angolan government in its post-conflict reconstruction efforts, and the extent to which these efforts have promoted durable peace in the country. The number of post-conflict countries on the continent is increasing, with 16 African countries already in the process of implementing peace agreements signed during the last decade. With research showing that up to 50 percent of post-conflict countries relapse into violent conflict within five to 10 years of signing a peace agreement, implementing practical and effective strategies to prevent a return to conflict becomes imperative. In the light of the limited experience of African countries in post-conflict situations, Angola presented an interesting case study. The oil and diamond rich country, emerging in 2002 from over 40 years of conflict, has been able to develop its own homegrown post-conflict reconstruction strategies. Notable progress in addressing some of its short-term post-conflict reconstruction priorities include, the successful resettlement of an estimated four million internally displaced persons (IDPs), and reintegrating more than half a million refugees and over 100 000 ex-combatants, into Angolan society. Progress in the areas of de-mining, as well as the rehabilitation of physical infrastructure, and increased enrolment in primary school education are other significant achievements. It is noteworthy that the Angolan government has, despite a lack of major international funding and overseas development assistance, been able to finance the majority of the expenses required for the country's reconstruction and re-Iaunching of the national economy. Importantly, the government's efforts have had some assistance in the form of oil-backed loans from China. Despite notable progress, such as the country's rapid economic growth, and being ranked 59th among the world's economies, Angola remains one of the most badly governed, corrupt, and unequal societies in the world. Credible improvements in the areas of good governance, socio-economic development, especially basic service delivery, and a more even distribution of the benefits of the country's oil wealth are vital in order to deliver significant peace dividends to the majority of the Angolan population. Making these improvements will be vital, and will influence considerably whether the country's post-conflict reconstruction efforts are ultimately successful.

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Management from the NOVA – School of Business and EconomicsNowadays, direct marketing tools are being used by companies that want to expand their businesses, aim to distinguish its customer service and improve its stakeholders’ relationship. HOLOS Mobile, developed by the Portuguese software company HOLOS S.A. throughout a partnership with Google, is an innovative product that can be used in any device that have access to internet (PC/3G cell phones/PDA). This software enables companies to analyse data and generate knowledge management concerning business models, namely consumer behaviour, targeting, and segmentation of markets. In addition, this tool will indirectly benefit several players in the market and will gain advantage to the traditional marketing methods used, creating a new concept of relationship marketing. This product is currently being customized by HOLOS to Banco Espírito Santo (BES) and although is still not possible to predict if this pioneering application will follow the tendency of success that other HOLOS’ products achieved, there are positive insights regarding its potential, giving initial trials and testing. After the investment done by InovCapital in the company, HOLOS Board decided it was time to expand its activities to emergent markets. The objectives to reach with this international expansion are focused in capture new business opportunities, increase sales, maintain a competitive advantage and increase reputation among companies in the industry. HOLOS believes that Angola is an attractive target market and that deeply needs for ICT solutions. The stable environment that is started to be lived in the country, together with the historical, linguistic and cultural connections with Portugal gives HOLOS a first mover advantage when compared to possible competitors. Based on my research and the environmental conditions, I developed an internationalization strategic plan of measures and recommendations that aim to support HOLOS’ entrance in the Angolan market and further commercialization of its new product, HOLOS Mobile.
