Entendemos, assim, as duas obras como representações do sistema escravagista e da vida do escravo, no caso, especificamente, de Northup, servindo como mediadoras do trauma cultural na sociedade norte-americana e influenciando a forma como a identidade do afro-americano é construída. Pretendemos estudar o gênero narrativas de escravos, contextualizando a autobiografia de Northup, com o intuito de analisá-la especificamente. Utilizaremos, então, autores como Olney (1984), Lingold (2013), Pope (2014), Roy (2015), entre outros. Faremos, doravante, um exame sobre filmes comerciais com o tema escravidão, com o intuito de apontar como cada um deles dialoga com a sociedade na época de sua produção, tornando-se contradiscursos ao pensamento vigente. Basearemo-nos em Sklar (1978), Kellner (2001), Mascarello (2006) e Rosenstone (2015). Passaremos à análise do filme de McQueen, procurando indícios de uma nova abordagem do tema escravidão no cinema, apontando, também, como, em diversos momentos, livro e filme se relacionam, seja na semelhança ou na diferença. A seguir, propomos uma reflexão sobre como as duas obras influenciaram e influenciam a construção da identidade do afro-americano, levando em consideração o trauma cultural legado pelo sistema escravagista na sociedade estadunidense. Apoiaremo-nos em textos de Cartmell e Hunter (2001), Browne e Kreiser Jr. (2004), Wilt e Shull (2004), Levine (2010), Ross (2010), Dubey (2010), Keizer (2010), Nigro (2011), Romney (2014), além dos de Eyerman (2001, 2011) e Pederson (2014), que falam especificamente sobre trauma cultural. Finalmente, faremos um breve levantamento de fatos e obras importantes que acontecem após o lançamento do filme, a fim de ressaltar a importância e relevância de 12 anos de escravidão para a continuação da discussão sobre a instituição peculiar norte-americana. / This research aims to reflect on 12 Years a Slave, regarding two media: the Solomon Northup novel (1853) and the Steve McQueen film adaptation (2013). Therefore, the two works are considered as representations of the slavery system and slave life, in Northup’s case, specifically, serving as cultural trauma mediators in the North-American society and influencing the way African-American identity is built. We intend to study the slave narrative genre, contextualizing Northup's autobiography, aiming to analyze it specifically. We will draw on authors such as Olney (1984), Lingold (2013), Pope (2014), Roy (2015), and others. Henceforth, we will examine commercial, slavery-themed movies, with the goal of pointing out how each of them dialogs with the society at the time of its production, becoming counter-discourses to the valid thinking then. We will be supported by Sklar (1978), Kellner (2001), Mascarello (2006), and Rosenstone (2015). We will carry on to the analysis of McQueen's movie, searching for indications of a new approach to the slavery theme in film, also pointing out how, in several moments, the novel and the movie relate to each other, whether in similarities or differences. After, we propose a reflection on how the two works have influenced the African-American identity construction, taking into consideration the cultural trauma left by the slavery system in the American society. We will draw on research conducted by Cartmell e Hunter (2001), Browne e Kreiser Jr. (2004), Wilt and Shull (2004), Levine (2010), Dubey (2010), Keizer (2010), Nigro (2011), Romney (2014), besides the ones of Eyerman (2001, 2011), and Pederson (2014), which specifically talk about cultural trauma. Finally, we will briefly yield data on important facts and works that happened after the movie launching, aiming to highlight the importance and relevance of 12 Years a Slave to the continuing of the discussion on this peculiar North-American institution.

Reed-Solomon code is nowadays broadly used in many fields of data transmission. Using of error correction codes is divided into two main operations: information coding before sending information into communication channel and decoding received information at the other side. There are vast of decoding algorithms of Reed-Solomon codes, which have specific features. There is needed knowledge of features of algorithms to choose correct algorithm which satisfies requirements of system. There are evaluated cyclic decoding algorithm, Peterson-Gorenstein-Zierler algorithm, Berlekamp-Massey algorithm, Sugiyama algorithm with erasures and without erasures and Guruswami-Sudan algorithm. There was done implementation of algorithms in software and in hardware. Simulation of implemented algorithms was performed. Algorithms were evaluated and there were proposed methods to improve their work.

Dans le cadre de l’avion plus électrique, les avionneurs cherchent à remplacer les commandes de vol hydrauliques par des commandes de vol électriques, avec pour intérêt de diminuer le poids, et d’améliorer la flexibilité des équipements aéronautiques. Sachant que sur un A380, la distance cumulée pour les câbles peut atteindre plus de 500 km, la solution consistant à faire cohabiter les transmissions de données et de puissances au sein de mêmes câbles grâce à la technologie CPL pourrait contribuer à réduire la masse de câble dans un avion. Cependant les câbles de puissance n’ont pas été dimensionnés pour transmettre un signal informationnel, et les équipements présents sur le réseau sont source de bruits. Dans ce contexte nous souhaitons montrer la faisabilité d’une transmission CPL soumise aux contraintes avioniques tout en respectant les normes aéronautiques. La première partie des travaux a consisté à mesurer le canal de propagation sur un banc de test représentatif d’un environnement aéronautique. Le canal de propagation est composé de deux coupleurs de type inductif ou capacitif dont le but est de connecter les câbles de télécommunication au réseau de puissance et d’une paire bifilaire torsadée de puissance d’une longueur de 32 m représentative d’un réseau HVDC ±270 V. Nous avons alors testé trois architectures différentes : l’architecture point-À-Point avec coupleur capacitif, l’architecture point-À-Point avec coupleur inductif et l’architecture point-À-Multipoints avec coupleur inductif. Le but de ces mesures a été d’évaluer la fonction de transfert du canal sur la bande [1 ; 100] MHz. Nous avons alors calculé les éléments caractéristiques du canal comme la bande de cohérence et l’étalement des retards. Après la caractérisation du canal de propagation, nous avons choisi et dimensionné les algorithmes de traitement du signal au regard des spécifications aéronautiques à savoir : un débit utile de 10 Mbit/s, un temps de latence de 167-334 μs, un TEB de 10-12 et le respect du gabarit de la DO-160 en émission conduite. Au regard de la fonction de transfert du canal, nous avons choisi d’utiliser l’OFDM comme technique de transmission. Ainsi, à l’aide de la caractérisation du canal de propagation nous avons au cours d’une étude paramétrique défini les paramètres de la transmission OFDM au regard des spécifications de débit et de temps réel. Dans un second temps, nous avons implanté les paramètres OFDM ainsi que la modélisation du canal de propagation dans une chaine de transmission Matlab. Cette chaine nous a alors permis de vérifier les paramètres issues de l’étude paramétrique ainsi que de définir le système de codage de canal (Reed-Solomon et code convolutif) pour respecter les spécifications aéronautiques. La dernière partie de cette thèse a consisté en l’étude du système de synchronisation. Du fait de la stabilité du canal de propagation, nous avons considéré une synchronisation fine du système lors d’une phase d’initialisation puis nous nous somme focalisé sur le dimensionnement d’un système de suivi dans le but de corriger le décalage de fenêtre FFT dû au défaut de fréquence d’échantillonnage. Pour limiter les pertes de débit lors de la phase de suivi, nous avons proposé une estimation de l’erreur de fréquence d’échantillonnage sur la phase des données reçues sur une période de 20 symboles OFDM. / In the new aircrafts, hydraulic flight control systems are replaced by electric flight control systems. The main interests are a better flexibility of the aeronautical equipments and a decrease in maintenance costs and construction costs, but the major problem is the increasing of the wires length. In order to decrease this length, it has been proposed to use power line communications (PLC) technology for flight control systems. The decrease of wire will first decrease aircraft weight and therefore the consumption of kerosene and on the other hand will simplify maintenance and construction. The first part of this work is the measurement and the characterisation of the propagation channel on an aeronautic test bench (with HVDC supply and loads). This channel is composed of two couplers (inductive or capacitive) in order to connect the telecommunication system on the power wires with galvanic isolation and one twisted pair of 32 m longs. We have tested three architectures: the point-To-Point architecture with capacitive coupler, the point-To-Point architecture with inductive coupler and the point-To-Multipoint architecture with inductive coupler. The purpose of these measurements is to measured the transfer function on the [1 ; 100] MHz bandwidth. Then, we have computed the channel parameters like the coherence bandwidth and the delay spread. The second step was the design of the signal processing algorithm in order to satisfy the aeronautical specifications: a useful bite rate of 10 Mbit/s, a latency of 167- 334 μs, a BER of 10-12 and the respect of the DO-160 gauge in conducted emissions. For the transmissions, we have chosen the OFDM technology which has been use with success in other PLC systems. With the channel characterization, we have proposed a parametric study in order to define the OFDM parameters to satisfy the bite rate and the real time constraints. After, we compute digital simulations with Matlab to check the OFDM parameters. With these simulations, we have also defined the channel coding parameters (Reed-Solomon and convolutional coding) to satisfy the aeronautical specifications. The last part of this study was the design of the synchronisation system. Because of the channel stability, we considered a precise synchronisation after an initialisation period. Then, we focus on the estimation of the FFT shift, due to the sampling frequency shift, during a following-Up period. In order to avoid the decrease of the latency and the bitrate due to the pilot symbols or pilot sub-Carriers insertion, we proposed to correct the FFT shift with the receive data thanks to the maximal likelihood algorithm.

In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation. Many coding methods aredesigned to improve the reliability of wireless channel. However, none of thesecoding methods could handle the burst errors that widely exist in wirelesschannel and are mainly responsible for packet corruption. Interleaving isintroduced to robust these coding methods and make those corrupted packetsavailable to be corrected by spreading the burst errors. The Reed-Solomon(15,7) block code is used as the forwarding error correction in theseexperiments. In this paper, seven different symbol interleaving will be firstlysimulated in the Matlab platform under four different channels to evaluate theirpacket error rate performances. Then, two of the seven interleaving with betterperformance and the simplest interleaving algorithm, general block interleavingwill be implemented in the TinyOS platform, and they will be compared witheach other from packet error rate, interleaving time and memory consumptionaspects. Experiments show that, for theoretical channel, interleaving plays animportant role to enhance the capability to correct the corrupted packets exceptfor Rayleigh channel, in which the impact of interleaving is generally slight.Meanwhile for the channel under IEEE 802.11b/g interference, interleavingenhance more than 10% PER in the receiver. However for MFA channel, theenhancement is slight, only 1.85%. Convolutional interleaving has the best PERperformance in AWGN channel and the channel with deterministic SER, whilematrix interleaving has the lowest PER in WLAN affected channel. In thelatency and memory consumption aspect, For the same packet length, generalblock interleaving has the shortest interleaving time while matrix interleavinghas the longest. In the same interleaving algorithm, the execution time becomeslonger with growth of packet size. Within the same interleaving method, thelonger the packet size is, the more memory that would be consumed. Under thesame interleaving length, general block interleaving consumes least memoryand convolutional interleaving has the largest memory consumption.

In this paper the performance of executing Cauchy Reed-Solomon (CRS) coding on the GPU is evaluated and compared with execution on the CPU. Three different prototypes are developed. One is sequential and developed in C++, the other two are developed utilizing C++ and OpenCL. The measurements are done by comparing the execution time of different data block sizes ranging from 16KB up to 256MB with two different encoding ratios, 9/12 and 10/16. The measurements are done on an Intel CPU with 4 cores with an integrated graphics card and an AMD graphics card. The OpenCL prototypes are executed with three different targets, the CPU, the integrated graphics card and the AMD graphics card. The sequential prototype is executed on the same CPU, but on a single core. The results from the measurements show that the GPU is faster than the CPU on larger data sizes. The highest measured throughput is achieved with the multithreaded CPU prototypes (OpenCL executed on the CPU) for sizes around 1MB. / I den här rapporten genomförs prestandatester för exekvering av Cauchy Reed-Solomon (CRS) coding på grafikkortet och jämförs med exekvering på en CPU. Tre olika prototyper har utvecklats. En är sekventiell och utvecklad i C++, de två andra är utvecklade i OpenCL och C++. Testerna genomförs genom tidtagning på olika stora datablock, från 16KB upp till 256MB med olika enkodnings ratios, 9/12 och 10/16. CPU:n som används i testerna är en Intel CPU med 4 kärnor, och grafikkorten som används är det integrerade grafikkortet på CPU:n samt ett grafikkort från AMD. OpenCL prototyperna exekveras med tre olika inställningar, CPU för multitrådat, det integrerade Intel grafikkortet och det dedikerade AMD grafikkortet. Den sekventiella prototypen exekveras på samma CPU, men med en kärna. Resultaten från experimenten visar att grafikkorten är snabbare än CPU:n för större datablock. Den prototyp som fick högst genomströmning av data var den multitrådade CPU prototypen för datablock i storleksordningen 1MB.

This thesis essays a comparative study of William Plomer's Turbott Wolfe (1925) and Sol Plaatje's Mhudi (1930). Although writing from very different subject positions within the social order of the time, Plomer and Plaatje embody in their novels a strikingly similar vision of a South Africa free of racial barriers. Plaatje's version of South African history in Mhudi deconstructs colonial binarism by dramatizing not only conflict and difference but also co-operation and commonality. Holding the past up as a mirror to the present, it protests against racial injustice while implying the continuing possibility of reconciliation. Plomer reacts angrily to white hypocrisy and insists on the rights and humanity of his African characters, in the name of imperatives both moral and political. He seeks additional sanction for these by situating the South African race questioning the context of a Western world slowly awakening to the consequences of modernity. During a time of political turbulence, both writers speak out boldly and confidently against the rising dominance of segregationist ideology. The imminent inception of full democracy in South Africa has reanimated the relevance of these writers' vision of a non- racial social order. If one of the challenges facing the South African literary historian 'today is the reconstruction of a truly national literary tradition, then Mhudi and Turbott Wolfe would appear to be key works in such an enterprise. As different as Plaatje's epic myth-making is from Plomer's modernist irony, both novels contrive to speak with a new voice: a national voice which expresses the aspirations of all South Africa's people. They are, moreover, novels whose survival seems guaranteed as much by their aesthetic qualities as by their ideological orientation. The novels are examined against the backgrounds of South African society and colonial literary production. They are seen as milestones in the development of a liberal South African literary tradition. By breaking with the dominant oppositional mode, whether that of "white writing" or an emergent "writing black", Plomer and Plaatje exemplify a literature at once socially relevant and possessed of a prophetic vision that remains of significance in South Africa today.
