Full textGNSS and particularly GPS and GLONASS systems are currently used in some geodetic applications to obtain a centimeter-level precise position. Such a level of accuracy is obtained by performing complex processing on expensive high-end receivers and antennas, and by using precise corrections. Moreover, these applications are typically performed in clear-sky environments and cannot be applied in constrained environments. The constant improvement in GNSS availability and accuracy should allow the development of various applications in which precise positioning is required, such as automatic people transportation or advanced driver assistance systems. Moreover, the recent release on the market of low-cost receivers capable of delivering raw data from multiple constellations gives a glimpse of the potential improvement and the collapse in prices of precise positioning techniques. However, one of the challenge of road user precise positioning techniques is their availability in all types of environments potentially encountered, notably constrained environments (dense tree canopy, urban environments…). This difficulty is amplified by the use of low-cost receivers and antennas, which potentially deliver lower quality measurements. In this context the goal of this PhD study was to develop a precise positioning algorithm based on code, Doppler and carrier phase measurements from a low-cost receiver, potentially in a constrained environment. In particular, a precise positioning software based on RTK algorithm is described in this PhD study. It is demonstrated that GPS and GLONASS measurements from a low-cost receivers can be used to estimate carrier phase ambiguities as integers. The lower quality of measurements is handled by appropriately weighting and masking measurements, as well as performing an efficient outlier exclusion technique. Finally, an innovative cycle slip resolution technique is proposed. Two measurements campaigns were performed to assess the performance of the proposed algorithm. A horizontal position error 95th percentile of less than 70 centimeters is reached in a beltway environment in both campaigns, whereas a 95th percentile of less than 3.5 meters is reached in urban environment. Therefore, this study demonstrates the possibility of precisely estimating the position of a road user using low-cost hardware

Full textEtt probabilistiskt verifierbart bevis (eng: Probabilistically Checkable Proof, PCP) av en matematisk sats är ett bevis skrivet på ett speciellt sätt vilket möjliggör en effektiv probabilistisk verifiering. Den berömda PCP-satsen säger att för varje familj av påståenden i NP finns det en probabilistisk verifierare som kontrollerar om en PCP bevis är giltigt genom att läsa endast 3 bitar från det. Denna banbrytande sats, och arbetena som ledde fram till det, lade grunden för många senare arbeten inom komplexitetsteorin, framförallt inom studiet av approximerbarhet av kombinatoriska optimeringsproblem. I denna avhandling fokuserar vi på en bred klass av optimeringsproblem i form av villkorsuppfyllningsproblem (engelska ``Constraint Satisfaction Problems'' CSPs). En instans av ett CSP av aritet k ges av en mängd variabler som tar värden från någon ändlig domän, och ett antal villkor som vart och ett beror på en delmängd av högst k variabler. Målet är att hitta ett tilldelning av variablerna som samtidigt uppfyller så många som möjligt av villkoren. En alternativ formulering av målet som ofta används är Gap-CSP, där målet är att avgöra om en CSP-instans är satisfierbar eller långt ifrån satisfierbar, där den exakta innebörden av att vara ``långt ifrån satisfierbar'' varierar beroende på problemet.Först studerar vi booleska CSPer, där domänen är {0,1}. Den fråga vi studerar är svårigheten av att särskilja satisfierbara boolesk CSP-instanser från instanser där den bästa tilldelningen satisfierar högst en andel epsilon av villkoren. Intuitivt, när ariten ökar blir CSP mer komplexa och därmed bör svårighetsparametern epsilon avta med ökande aritet. Detta visar sig vara sant och ett första resultat är att för booleska CSP av aritet k är det NP-svårt att särskilja satisfierbara instanser från dem som är högst 2^{~O(k^{1/3})}/2^k-satisfierbara. Vidare studerar vi färgläggning av grafer och hypergrafer. Givet en graf eller en hypergraf, är en färgläggning en tilldelning av färger till noderna, så att ingen kant eller hyperkant är monokromatisk. Problemet vi analyserar är att särskilja instanser som är färgbara med ett litet antal färger från dem som behöver många färger. För grafer visar vi att det finns en konstant K_0>0, så att för alla K >= K_0 är det NP-svårt att särskilja grafer som är K-färgbara från dem som kräver minst 2^{Omega(K^{1/3})} färger. För hypergrafer visar vi att det är kvasi-NP-svårt att särskilja 2-färgbara 8-likformiga hypergrafer som har N noder från dem som kräv minst 2^{(log N)^{1/4-o(1)}} färger. Samtliga dessa resultat bygger på konstruktioner av PCPer med perfekt fullständighet. Det vill säga PCPer där verifieraren alltid accepterar ett korrekt bevis. Inte bara är detta en mycket naturlig egenskap för PCPer, men det kan också vara ett nödvändigt krav för vissa tillämpningar. Konstruktionen av PCPer med perfekt fullständighet för NP-påståenden ger tekniska komplikationer och kräver delvis utvecklande av nya metoder. Vårt booleska CSPer resultat och vårt Färgläggning resultat bevisas genom att anpassa ``Direktsumman-metoden'' introducerad av Siu On Chan till fallet med perfekt fullständighet. Vårt bevis för hypergraffärgningssvårighet förbättrar och förenklar ett färskt resultat av Khot och Saket, där de föreslog begreppet superpositionskomplexitet av CSP.

A Gestão de Projetos por Corrente Crítica (Critical Chain Project Management – CCPM), uma abordagem fundamentada na Teoria das Restrições, tem apresentado alguns resultados efetivos na condução tanto de empreendimentos únicos quanto de vários simultaneamente. Apesar disso, a literatura pouco estudou esta abordagem para o desenvolvimento de produtos e na gestão de seu portfólio, áreas em que a Gestão de Projetos desempenha papel importante, e, especificamente, seus impactos no desempenho. Assim, o objetivo geral desta pesquisa é analisar a relação entre a aderência a preceitos e práticas da CCPM e o desempenho do portfólio de produtos em empresas. Para cumprir com estes objetivos, foi desenvolvida uma pesquisa survey, com uma amostra de 79 empresas. Os resultados indicam que empresas praticantes de conceitos e ferramentas sugeridos pela CCPM apresentam melhores resultados, estatisticamente significativos, para os três fatores de desempenho em Gestão de Portfólio de Produtos adotados por esta pesquisa. Este estudo ainda aprofunda o conhecimento em CCPM e portfólio de produtos, ao estudar, por meio de testes não-paramétricos, a influência de algumas variáveis, como o nível de turbulência do ambiente organizacional, nos constructos desta pesquisa. Verificou-se que não houve diferença significativa entre os fatores pesquisados e o nível de turbulência do ambiente. Além disso, as empresas que afirmaram adotar o guia PMBOK® utilizaram mais as práticas de CCPM.
The Critical Chain Project Management (CCPM), an approach based on the Theory of Constraints, has shown effective results in driving both single projects and concurrent multiple projects. Despite this, the literature has little studied this approach to product development and portfolio management, areas in which Project Management plays an important role, and specifically its impact on performance. Thus, the overall objective of this research is to analyze the relationship between adherence to rules and practices of CCPM and portfolio performance of the company's products. In order to meet these objectives, a survey research through a questionnaire was developed, conducted with 79 companies. The results show that companies adopting concepts and tools suggested by CCPM have better results, statistically significant, for the three performance factors in Product Portfolio Management adopted by this research. This research further deepens the CCPM and product portfolio knowledge, studying, by non-parametric tests, the influence of some variables, such as the level of turbulence in the organizational environment, in the research constructs. It was verified that there was no significant difference between the studied factors and the level of environmental turbulence. In addition, companies that have adopted the PMBOK® guide have used CCPM practices more.

Nowadays, content distribution services comprise most of the Internet traffic, and about half of them is contributed by video streaming. Live streaming (LS), which provides people a way to share what are currently happening in the world, will be one of the main streams of video services on the Internet. Playback delay, the time interval between events occur and the event video are watched by LS users, is the most important metric of LS systems. In this paper, we focus on providing LS services in tree-based P2P networks, so that systems could serve more users under high bandwidth requirement and maximum playback delay constraint. We proposed two algorithms: PCL algorithm, and local optimization algorithm. PCL places newly joining peers in the tree properly so that peers which contribute more upload bandwidth could experience lower playback delay, and local optimization aims to lower the average system playback delay in distributed manner. The simulation result indicates that our algorithms allow systems to serve more users than the system which adopts an algorithm that only considers playback delay. In addition to the simulation work, we have implemented a tree-based P2P LS prototype, which allows us to verify/improve the future proposed algorithms in real Internet.
