Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Neste trabalho, foi desenvolvido um simulador numérico baseado no método livre de malhas Smoothed Particle Hydrodynamics (SPH) para a resolução de escoamentos de fluidos newtonianos incompressíveis. Diferentemente da maioria das versões existentes deste método, o código numérico faz uso de uma técnica iterativa na determinação do campo de pressões. Este procedimento emprega a forma diferencial de uma equação de estado para um fluido compressível e a equação da continuidade a fim de que a correção da pressão seja determinada. Uma versão paralelizada do simulador numérico foi implementada usando a linguagem de programação C/C++ e a Compute Unified Device Architecture (CUDA) da NVIDIA Corporation. Foram simulados três problemas, o problema unidimensional do escoamento de Couette e os problemas bidimensionais do escoamento no interior de uma Cavidade (Shear Driven Cavity Problem) e da Quebra de Barragem (Dambreak). / In this work a numerical simulator was developed based on the mesh-free Smoothed Particle Hydrodynamics (SPH) method to solve incompressible newtonian fluid flows. Unlike most existing versions of this method, the numerical code uses an iterative technique in the pressure field determination. This approach employs a differential state equation for a compressible fluid and the continuity equation to calculate the pressure correction. A parallel version of the numerical code was implemented using the Programming Language C/C++ and Compute Unified Device Architecture (CUDA) from the NVIDIA Corporation. The numerical results were validated and the speed-up evaluated for an one-dimensional Couette flow and two-dimensional Shear Driven Cavity and Dambreak problems.

The development of the first method - sequential and hybrid - comes from the deficiency of current approaches to provide a good neighborhood space exploration. Being constructed from the combination of two meta-heuristics, standard C-GRASP and Continuous General Variable Neighborhood Search (C-GVNS), as a strategy to achieving symmetric trades of neighborhood structures, it performed efficiently in the computational tests that were taken. The second procedure arises from the large consume of time when using high dimension functions with the standard C-GRASP construction procedure. As the optimization problems have a high dimensionality increase, it s preferable to have two parallel versions of the optimization method in order to handle bigger problems. Thus, for this new procedure developed, it was used the Compute Unified Device Architecture (CUDA), which provided promising acceleration regarding the processing time, based on the experiments performed. / O presente trabalho aborda o Problema de Otimização Global Contínua, em sua forma de minimização, através de duas abordagens para o procedimento Continuous Greedy Randomized Adaptive Search Procedure (C-GRASP). A elaboração do primeiro método, sequencial e híbrido, parte da deficiência presente nas abordagens atuais, em promover boa exploração no espaço de vizinhança. Sendo constituída da combinação de duas meta-heurísticas, C-GRASP padrão e Continuous General Variable Neighborhood Search (C-GVNS). Como estratégia para a realização de trocas sistemática de estruturas de vizinhanças, mostrou-se eficiente aos testes computacionais realizados. O segundo procedimento elaborado parte do grande consumo de tempo ao utilizar funções com alta dimensão, pelo procedimento de construção do método C-GRASP padrão. Como os problemas de otimização possuem crescimento elevado de dimensionalidade, é desejável ter versões paralelas do método de otimização para lidar com os problemas maiores. Desta forma, para o novo procedimento elaborado foi empregado a plataforma de computação paralela Compute Unified Device Architecture (CUDA), que, conforme verificado nos experimentos realizados, promoveu promissora aceleração quanto ao tempo de processamento.

Os métodos numéricos convencionais, baseados em malhas, têm sido amplamente aplicados na resolução de problemas da Dinâmica dos Fluidos Computacional. Entretanto, em problemas de escoamento de fluidos que envolvem superfícies livres, grandes explosões, grandes deformações, descontinuidades, ondas de choque etc., estes métodos podem apresentar algumas dificuldades práticas quando da resolução destes problemas. Como uma alternativa viável, existem os métodos de partículas livre de malhas. Neste trabalho é feita uma introdução ao método Lagrangeano de partículas, livre de malhas, Smoothed Particle Hydrodynamics (SPH) voltado para a simulação numérica de escoamentos de fluidos newtonianos compressíveis e quase-incompressíveis. Dois códigos numéricos foram desenvolvidos, uma versão serial e outra em paralelo, empregando a linguagem de programação C/C++ e a Compute Unified Device Architecture (CUDA), que possibilita o processamento em paralelo empregando os núcleos das Graphics Processing Units (GPUs) das placas de vídeo da NVIDIA Corporation. Os resultados numéricos foram validados e a eficiência computacional avaliada considerandose a resolução dos problemas unidimensionais Shock Tube e Blast Wave e bidimensional da Cavidade (Shear Driven Cavity Problem). / The conventional mesh-based numerical methods have been widely applied to solving problems in Computational Fluid Dynamics. However, in problems involving fluid flow free surfaces, large explosions, large deformations, discontinuities, shock waves etc. these methods suffer from some inherent difficulties which limit their applications to solving these problems. Meshfree particle methods have emerged as an alternative to the conventional grid-based methods. This work introduces the Smoothed Particle Hydrodynamics (SPH), a meshfree Lagrangian particle method to solve compressible flows. Two numerical codes have been developed, serial and parallel versions, using the Programming Language C/C++ and Compute Unified Device Architecture (CUDA). CUDA is NVIDIAs parallel computing architecture that enables dramatic increasing in computing performance by harnessing the power of the Graphics Processing Units (GPUs). The numerical results were validated and the speedup evaluated for the Shock Tube and Blast Wave one-dimensional problems and Shear Driven Cavity Problem.

These huge amount of models into an important scene are called crowds. The crowds needs a high computer performance and specific algorithms in their interaction control to avoid immersion loss into a game by problems which may happen if the crowds are not treated accordingly. With the popularization of graphic board languages like NVIDIA CUDA, new algorithms were created to easily increase the performance of crowds in digital games and their overwhelming superiority compared to the methods used in linear programming were proved in many researches. The goal of this work is to use these GPU techniques as base to implement a new API using CUDA language that will present better performance and simplicity compared to the others algorithms on the area of crowds in digital games. After the project conclusion, the created API turned easier the crowd treatment to digital game developers using Unity3D integrated with API TBX, that now only need to include a DLL in the project instead creating na algorithm for crowd treatment from the beginning, which takes a huge amount of time from development. / O histórico dos jogos digitais apresenta, desde seu princípio, jogos que utilizam diversos modelos de inimigos para enfrentar ou diversos modelos de personagens para controlar, como os jogos Real-Time Strategy por exemplo. Essas grandes quantidades de modelos que compõem uma cena importante são chamadas de multidões. As multidões necessitam de um alto poder computacional e algoritmos específicos para seu tratamento para evitar a perda de imersão dentro de um jogo pelos problemas que podem acontecer caso as multidões não sejam tratadas adequadamente. Com o surgimento de linguagens de placas gráficas como a NVIDIA CUDA, novos algoritmos foram criados para melhor trabalhar com o desempenho de multidões em jogos digitais e sua superioridade em comparação com os métodos utilizados em programação sequencial foi comprovada em diversos estudos. O objetivo deste trabalho é se basear nestas técnicas de GPU para implementar uma nova API usando tecnologia CUDA que visa melhorar os algoritmos existentes para tratamento de multidões em jogos digitais em termos de desempenho e simplicidade de implementação. Com a conclusão do projeto, a API criada facilitou o tratamento de multidões para desenvolvedores de jogos digitais com a game engine Unity3D integrada com a API TBX de simulação de multidões, que agora apenas precisam incluir uma DLL em seu projeto ao invés de criar um algoritmo próprio de tratamento de multidões do início, o que demanda tempo de desenvolvimento.

The Standard Model of particle physics which attempts to describe all matter and all forces in the universe (except gravity),has been in agreement with most of the experiments till date. However theoretically and phenomenologically many questions remain unanswered in the SM. The present and future colliders will help the physicists learn more about the nature of matter and all forces in the universe. In this thesis work we have mainly focused on the physics case of the future linear collider which will be a succession of the presently running Large Hadron Collider in CERN Geneva. As an introduction to the thesis work in Chapter 1 we have discussed in detail about the most planned future collider the International Linear Collider. This collider apart from being a high luminosity machine will have the advantage of beam polarization. Chapter 2 discusses about the basis structure of the Standard Model, along with its many unanswered questions. Some of the theories proposed to take care of these deficiencies are also discussed. These theories apart from explaining the shortcomings of the SM, also predicts many new particles and are thus phenomenologically rich. Exploration of these new physics scenarios can be done many ways. A detailed investigation of the direct production of particles which are not present in the SM spectrum, is one of the techniques provided the particles are within the collider reach. The other is an indirect way, where deviations from SM is studied by a through scrutinization of the SM processes. Provided new physics is observed in either of the way, in the present or future colliders it becomes necessary to pin point them. The main objective of this thesis work has been to look for various scenarios, both in a direct and indirect way and identify them. The different cases of beam polarization is also explored. Overall we find that the full potential of the linear collider can be realized only with the availability of the electron and positron beam polarization, both transverse and longitudinal. We give an overview of the importance of beam polarization and its inclusion in the calculation of e+e- collisions in Chapter 3. In Chapter 4 we have considered the possibility of finger printing the presence of heavy additional Z′bosons that arise naturally in extensions of the Standard Model such as E6 models and left-right symmetric models, through their mixing with the standard model Z boson. They are probed using W pair production and leptonic decay of one of the W’s. The Littlest Higgs Model which addresses the hierarchy problem and where the Z′arises naturally is also considered. By considering a class of observables including total cross sections, energy distributions and angular distributions of decay leptons we find significant deviation from the Standard Model predictions for these quantities with right-handed electrons and left-handed positrons at √s=800 GeV. This process complements the study of fermion pair production processes that have been considered before for discrimination between these models. We have then studied the possibility of identifying a strongly interacting Wboson sector inChapter5 which is consistent with present day Large Hadron Collider searches, at the International Linear Collider with longitudinal as well as transversely polarized electron and positron beams. We account for the final state interaction using a suitable Omnes formalism in terms of a plausible resonance description, and carry out thorough analyses of cross sections, asymmetries and angular distributions of the Ws. In order to have a fully comprehensive study we also carry out a comparison with other extensions of the Standard Model, where an s channel resonance like heavy additional Z′bosons arise naturally. We also consider the effect of the strong final state interaction on a correlation that depends on(φ- - φ+), where the φ∓are the azimuthal angles of decay leptons, and find that it is a useful discriminant. The importance of top polarization in the process e+e−→ tt with transverse beam polarization to probe interactions of the scalar and tensor type beyond the Standard Model and the way to disentangle their individual contributions is discussed in Chapter 6. 90% confidence level limits on the interactions with realistic integrated luminosity are presented and are found to improve by an order of magnitude compared to the case when the spin of the top quark is not measured. Sensitivities of the order of a few times 10−3 TeV−2 for real and imaginary parts of both scalar and tensor couplings at √s=500 and 800 GeV with an integrated luminosity of 500 fb−1 and completely polarized beams is shown to be possible. We next consider the process e+e- → γ Z with transverse beam polarization in the presence of anomalous CP-violating γZZ coupling λ1 and γγZ coupling λ2 in Chapter 7. We point out that similar to the approach in Chapter 6 if the final-state spins are resolved, then it becomes possible to fingerprint the anomalous coupling Reλ1. 90% confidence level limit on Reλ1 achievable with center-of-mass energy of 500 GeV or 800 GeV with realistic initial beam polarization and integrated luminosity is of the order of few times of 10−2 when the helicity of Zis used and 10−3 when the helicity of γis used. The resulting corrections at quadratic order to the cross section and its influence on these limits are also evaluated and are shown to be small. In Chapter 8 the production of the lightest neutralinos in the radiative process e+e−→ χ˜10χ˜10γ in supersymmetric models with grand unification is considered. We consider models wherein the standard model gauge group SU(3)c x SU(2)L x U(1)Y is unified in to the grand unified gauge groups SU(5),or SO(10). We compare and contrast the dependence of the signal cross section on the grand unified gauge group, and different representations of the grand unified gauge group, into which the standard model gauge group is unified. We carry out a comprehensive study of the radiative production process which includes higher order QED corrections in our calculations. In addition we carry out a detailed study of the background to the signal process coming from the Standard Model radiative neutrino production e+e−→ νv*γ, as well as from the radiative production of the scalar partners of the neutrinos (sneutrinos) e+e ν˜ν˜γ. The latter can be a major supersymmetric background to the radiative production of neutralinos when the sneutrinos decay invisibly. Finally in Chapter 9, we conclude and present the summary of the thesis.

Idag kommer fler och fler i kontakt med nya digitala tekniker både inom yrket men även privat. Det är därför viktigare än någonsin att de digitala verktygen når upp till slutanvändares förväntningar såväl som krav. Syftet med denna studien var att undersöka fenomenet digital acceptans. Därför valdes modeller och teorier för utvärdering ut för att jämföras mot individens upplevelser och acceptans av digitala verktyg. En teoretisk grund har lagts genom att samla in och analysera nio modeller för utvärdering av system och användaracceptans, där tre modeller valdes ut. Studien har genomförts med hjälp av intervjuer där respondenter från olika yrkesbakgrunder har fått möjligheten att berätta om sina upplevelser kring digitaliseringen. Materialet från dessa intervjuer har därefter analyserats för att kategoriseras i olika teman med underkategorier, detta tillät undersökningen att jämföra resultatet från intervjuerna med aktuell forskning. Utifrån slutsatsen har studien tagit fram ett förslag på en konceptuell modell för hur acceptans av digitala verktyg skulle kunna se ut. / Today, more and more people come into contact with new digital technologies both in their profession but also privately.

Företagsvärlden omfattas av hård konkurrens som kräver en ständig utveckling av produkter, personal och verksamheten. Utvecklingen sker på bekostnad av hårda krav i arbetsbeskrivningar där ständigt förbättringsarbete ingår i arbetsrollen hos individerna. För att kunna sammanlänka ständiga förbättringar med verksamhetens välmående behövs ett strukturerat förbättringsarbete i form av en väl fungerande förslagsverksamhet. Förslagsverksamhetens syfte är att utnyttja erfarenheter och kunskaper från alla medarbetare genom att stimulera individernas kompetens och idégenerering för att sedan bidra med innovativa och konkurrensmässiga förbättringsförslag. Personal är en resurs som omfattar säregna kunskaper som inget annat företag kan kopiera, därför bör den användas till högsta grad. Syftet med examensarbetet är att kartlägga och ange förbättringsåtgärder för förslagsverksamhetsprocessen vid GKN Aerospace Sweden AB i Trollhättan. Arbetet bestod av en inledande litteraturstudie som innehöll indirekta och direkta faktorer som påverkar förbättringsarbetet med en koppling till förslagsverksamheters funktioner. För att konkretisera den teoretiska referensramen om verktygens innebörd till förbättringsarbetet utfördes en teoretisk samt en praktisk benchmarking. Företagets nuvarande förslagsverksamhet kartlades och analyserades för att sedan bygga en grund för kommande förbättringsförslag.GKN Aerospace Sweden är en del av GKN-koncernen som är verksam i fler än 30 länder runt om i världen och har ca 50 000 anställda. Företaget tillverkar komponenter till flyg- och raketmotorer samt utför service och underhåll. I dagsläget arbetar GKN Aerospace med en förslagsverksamhet som är beroende helt av ett internt IT-system och har en medelledtid på 43 veckor till beslut om belöning och åtgärd. Belöningar för förslag som inkommer är ekonomiska och beräknas fram genom en specifik belöningsformel. Hela förslagsverksamhetsprocessen är omfattande och i den ingår flertalet loopar för behandling av förslag. Examensarbetet resulterade i förbättringsförslag utifrån studier och nulägesanalys men skiljs åt från det förväntade målet att förbättra och utveckla nuvarande system. Problemet som uppkom var att nuvarande system inte stödjer verksamhetens förväntningar på förslagsverksamheten. Det resulterade i att ett helt nytt system med tillhörande rutiner och belöningsriktlinjer togs fram för att skapa incitament och högre motivation för inlämnandet av förbättringsförslag. Förbättringsförslagen mynnade ut i: avsatt tid, förbättringsarbete i grupp, uppstartsmöte, ny process, underlag för utveckling av nytt IT-system, ekonomisk och symbolisk belöning. / The business world is constantly subject to intense competition that requires continuous development of products, personnel and operations within the company. The development towards a better state comes at the expense of strict requirements in job descriptions where continuous improvement is part of the working role of individuals. In order to link the continuous improvement of the business well-being, there is a need of structured work for improvement in ways of a well-functioning suggestion scheme. Suggestion schemes main purpose is to utilize the experience and knowledge of all employees by encouraging individuals' skills and creativity, which will contribute with innovative and competitive suggestions. Personnel is a resource that covers particular knowledge that no other company can copy; therefore it should be utilized to the maximum extent possible. The aim of the project is to identify and specify improvement measures for the suggestion scheme at GKN Aerospace Sweden AB in Trollhättan. The work consisted of an initial literature review, which included direct and indirect factors effecting the continuous improvement with linkage to the proposed suggestion scheme. In order to concretize the theoretical framework of the tools main purpose for the continuous improvement, a theoretical and a practical benchmarking was utilized. The company's current suggestion scheme was mapped and analyzed, and a foundation for future improvements was established.GKN Aerospace Sweden is part of the GKN Group, which operates in more than 30 countries around the world and employs about 50 000 individuals. The company manufactures components for aircraft and rocket engines, as well as service and maintenance. In the current situation GKN Aerospace manages a suggestion scheme that depends entirely on an internal IT system and has an average lead time of 43 weeks until a decision is made. The reward system for received suggestions is an economic reimbursement calculated through a complex formula. The entire suggestion scheme process is extensive and includes several loops for conducting the evaluation of suggestions. The thesis resulted in improvement propositions based on studies and situation analysis, but differs from the expected target to improve and develop the current system. The problem that arose was that the current system does not support the company's expectations for the suggestion scheme process. It resulted in a completely new system with associated procedures and reward guidelines were developed to create incentives and higher motivation for the submission of suggestions for improvement. The improvement propositions resulted in: dedicated time for improvements, group-based activities for continuous improvements, start-up meetings, new process, basis for the development of a new IT system, economic and symbolic rewards.Date: 2015-

Unified Diagnostic Service (UDS), which is an international and not a company-specific standard, is used in almost all new electronic control units (ECUs) by now. Modern vehicles have a diagnostic interface for off-board diagnostics, which makes it possible to connect a diagnostic tool to the vehicle’s bus system like Controller Area Network (CAN) and Local Interconnect Network (LIN). However, as the most commonly used method, sequential method on the UDS data transmission over LIN does not only result in low reliability and flexibility but also fails to meet the standard for LIN development defined in the latest LIN specification published by the consortium. With standard workflow and application interfaces, this Master Thesis will develop and evaluate a database-based method to build a UDS system over LIN, where all the information for the network is defined in the LIN database, and the protocol properties are realized in a reusable model so that it can be easily reconfigured for the future development of other services. As a result, a new method including a layered-structure LIN protocol model and a LIN database has been successfully designed and implemented. The prototype is built on the device PIC32MX795, and the database can be deployed by the configuration tool to specify the UDS communication schedule. Further, several performance evaluations have been performed. The tests indicate that the system is qualified on the limited hardware platform and the configuration flexibility is proved by different databases. / Unified Diagnostic Service (UDS), som är en internationell och inte en företagsspecifik standard, används nu i nästan alla nya elektroniska styrenheter (ECU). Moderna fordon har ett diagnostiskt gränssnitt för diagnostik utanför kortet, vilket gör det möjligt att ansluta ett diagnostiskt verktyg till fordonets bussystem som Controller Area Network (CAN) och Local Interconnect Network (LIN). Som den mest använda metoden resulterar emellertid sekventiell metod på UDS-dataöverföringen via LIN inte bara i låg tillförlitlighet och flexibilitet utan uppfyller också standarden för LINutveckling som definieras i den senaste LIN-specifikationen publicerad av konsortiet. Med standard arbetsflöde och applikationsgränssnitt kommer denna masteruppsats att utveckla och utvärdera en databas-baserad metod för att bygga ett UDS-system över LIN, där all information för nätverket definieras i LIN-databasen, och protokollegenskaperna realiseras i en återanvändbar modell så att den enkelt kan konfigureras för framtida utveckling av andra tjänster. Som ett resultat har en ny metod som inkluderar en LIN-protokollmodell med skiktstruktur och en LIN-databas framgångsrikt designats och implementerats. Prototypen är byggd på enheten PIC32MX795, och databasen kan konfigureras av verktyget för att ange UDSkommunikationsschema. Vidare har flera prestationsutvärderingar genomförts. Testen indikerar att systemet är kvalificerat på den begränsade hårdvaruplattformen och konfigurationsflexibiliteten bevisas av olika databaser.
