Testo completoAbstract (sommario):
This paper explores the practical teachings found in the Dunhuang manuscript of the Platform Sutra of the Sixth Patriarch and considers the possibility of practice within a doctrine of sudden enlightenment. Part One outlines how the doctrine of sudden enlightenment can be understood to undermine the purpose for practicing meditation. Part Two first makes a case for the position that practice is presupposed by the text regardless of the doctrine of sudden enlightenment. Next the paper argues for what type of meditation practice the Platform Sutra teaches is consistent with sudden enlightenment. The practice the Platform Sutra teaches is an intentionless, continuous, non-passive non-attachment while in the midst of dharmas that takes as its basis the suchness of things inherent in sentient beings.

Chunked DASH is getting attention for reducing otherwise high delay oflive segment streaming but there are a lot of unexplored problems associatedwith it. This master’s thesis investigates the difficulties involved withimplementing a chunked DASH player in the browser with JavaScript. A small system containing one JavaScript client and a server which simulateslive streaming by repeating VOD segments is implemented. Issuesrelated to the downloading of chunked segments are addressed and solvedsuch that chunked segments can be streamed within expected delay, andwith accurate throughput metrics.Chunkad DASH får uppmärksamhet för sin förmåga att minska annars hög fördröjning vid segmentbaserad direktsändning, men det finns många associerade problem som inte har utforskats i någon större utsträckning. Denna masters avhandling undersöker svårigheterna med att implementera en chunkad DASH-spelare i webbläsaren med JavaScript. Ett litet system som innehåller en JavaScript-klient och en server som simulerar direktsändning genom att upprepa VOD-segment implementeras. Frågor relaterade till nedladdning av chunkar behandlas och löses så att innehållet kan sändas inom förväntad fördröjning och med pålitliga mätvärden av genomströmmning.

Dynamic Adaptive Streaming over HTTP (DASH) is a convenient approach to transfer videos in an adaptive and dynamic way to the user. Therefore, this system makes best use of the bandwidth available. In this thesis, we investigate Dynamic Adaptive Streaming over HTTP (DASH) based on data collected from the lab experiments and user’s experiments. The objectives include investigation of how three different DASH players behave at different network conditions and up to which limit the players are tolerating the disturbances. We summarized the outcome of lab experiments on DASH at different adverse conditions and checked the lab results with user quality of experience at different adverse conditions to see up to which extent the users could tolerate the disturbances in different DASH players.

Testo completoAbstract (sommario):
Multi-video streaming allows the viewer to interact with the stream by choosing andswitching between several different camera angles to view the stream from. For this reportwe implement and evaluate adaptive multi-video streaming with dash.js. With the help ofdash.js and self-made additions, multiple parallel video streams which are synchronized intime are implemented to provide a good user experience with smooth switching betweenstreams. These streams will be delivered according to dash.js own HTTP-based AdaptiveStreaming algorithms to achieve adaptive streams for varying conditions. In order to optimizethe usage of the available bandwidth in terms of video quality in a multi-videoenvironment we implement probabilities of camera switching to adapt qualities and allocatedbandwidth of streams. By utilizing the functions of dash.js we create two prefetchingpolicies and analyze these results together with the standard non-prefetch dash.js implementationin a multi-view video environment. Our results present the improvements interms of stalling with a prefetch implementation and the possibility of a good policy tofurther optimize a multi-view video implementation in terms of stalling, quality and bandwidthusage. Evaluation of dash.js compatibility for a multi-view video environment is alsodiscussed where pros and cons of dash.js in their current state are presented.

Novas formas terapêuticas e o progresso da medicina proporcionaram a emergência de infecções por Rhodotorula mucilaginosa em pacientes imunocomprometidos. Este estudo tem o objetivo de avaliar a suscetibilidade dos isolados de R. mucilaginosa aos antifúngicos convencionais, verificar a habilidade destes em modificar seu perfil de suscetibilidade após exposição a crescentes concentrações de anfotericina B (AMB) e comparar a atividade antifúngica de AMB ou voriconazol (VCR) em combinação com fármacos diversos frente aos dois grupos de R. mucilaginosa. Trinta e cinco isolados de R. mucilaginosa proveniente de pacientes foram estudados. Os isolados foram identificados baseado em métodos microbiológicos e moleculares. Definimos como grupo I os isolados fúngicos originais e grupo II como estes mesmos isolados após serem submetidos a crescentes concentrações de AMB. A exposição à AMB foi realizada segundo Fekete-Forgács et al., com algumas modificações. Os testes de susceptibilidade foram realizados de acordo com a técnica de microdiluição em caldo (CLSI M27-A3). AMB, caspofungina, fluconazol e VRC foram testadas isoladamente e ciprofloxacino, levofloxacino, anlodipino, ciclosporina A, fluoxetina, ibuprofeno, sinvastatina e varfarina foram testadas em combinação com AMB ou VRC, utilizando a técnica de microdiluição em caldo “checkerboard”. Os isolados do grupo I foram suscetíveis a baixas concentrações de AMB. A suscetibilidade ao VCR foi muito reduzida. Fluconazol e caspofungina não exibiram atividade frente a R. mucilaginosa. A exposição prolongada à AMB modificou a suscetibilidade dos isolados. Os testes de suscetibilidade com os isolados do grupo II mostraram elevadas Concentrações Inibitórias Mínimas (CIMs) para AMB e a inibição pelo VCR requisitou CIMs mais elevadas. No grupo I, a combinação de AMB + ibuprofeno mostrou o maior número de interações sinérgicas. No grupo II, a combinação com o maior número de interações sinérgicas foi AMB + sinvastatina. No grupo I, quando VCR foi combinado com levofloxacino, um potente sinergismo foi observado frente a isolados de R. mucilaginosa. No grupo II, combinação de VRC + ciclosporina A mostrou um potente sinergismo. Os tratamentos para infecção por R. mucilaginosa são restritos e a terapia combinada pode ser uma alternativa quando novos fármacos são combinados com aqueles já disponíveis no mercado.New therapies and medical progress have led to emerging fungal infections by Rhodotorula mucilaginosa in immunocompromised patients. The objectives of this study were to evaluate the susceptibility profile of Rhodotorula mucilaginosa, verify the ability of this species to change its susceptibility profile after exposure to high concentrations of AMB, and compare the antifungal activity of AMB or voriconazole (VCR) plus combinations of non-antifungal medications against the two groups of R. mucilaginosa. Thirty-five strains of R. mucilaginosa isolated from patients were studied. The isolates were identified based on microbiological and molecular methods. We defined group I to be the original strains isolated from patients and group II as the same strains after in vitro exposure to AMB. AMB exposure was assayed according to Fekete-Forgács et al., with some modifications. Susceptibility tests were performed using the broth microdilution method (CLSI M27-A3). AMB, caspofungin, fluconazole (FLC), and VRC were tested alone and ciprofloxacin, levofloxacin, amlodipine, cyclosporine A, fluoxetine, ibuprofen, simvastatin, and warfarin were tested in combination with AMB or VRC, using the broth microdilution checkerboard technique. All group I isolates were susceptible to low concentrations of AMB. Susceptibility to VRC was quite poor. FLC and CAS exhibited no activity against R. mucilaginosa. Prolonged exposure to AMB changed the susceptibility of the isolates. The susceptibility tests with strains from group II showed high minimal inhibitory concentration (MICs) for AMB and the inhibition by VRC required more elevated MICs. In group I, the combination AMB + ibuprofen demonstrated the highest number of synergistic interactions. In group II, the most synergistic interactions was AMB + simvastatin. In group I, When VCR was combined with levofloxacin, a strong synergism was demonstrate against R. mucilaginosa isolates. In group II, VRC + cyclosporine A combination demonstrated a potent synergism. Treatments for R. mucilaginosa are restricted and a multidrug approach seems to be an alternative by administering novel chemical entity drugs with drugs currently on the market simultaneously.

Altamimi, Sadi. "QoE-Fair Video Streaming over DASH". Thesis, Université d'Ottawa / University of Ottawa, 2018. http://hdl.handle.net/10393/38591.
Testo completoAbstract (sommario):
Video streaming has become, and is expected to remain, the dominant type of traffic over the Internet. With this high demand for multimedia streaming, there is always a question on how to provide acceptable and fair Quality of Experience (QoE) for consumers of the over-the-top video services, despite the best-effort nature of the Internet and the limited network resources, shared by concurrent users. MPEG-DASH, as one of the most widely used standards of HTTP-based adaptive streaming, uses a client-side rate adaptation algorithms; which is known to suffer from two practical challenges: in one hand, clients use fixed heuristics that have been fine-tuned according to strict assumptions about deployment environments which limit its ability to generalize across network conditions. On the other hand, the absence of collaboration among DASH clients leads to unfair bandwidth allocation, and typically ends up in an unbalanced equilibrium point. We believe that augmenting a server-side rate adaptation significantly improves the fairness of network bandwidth allocation among concurrent users. We have formulated the problem as a Decentralized Partially Observable Markov Decision Process (Dec-POMDP) model, and used RL to train two neural networks to find an optimal solution to the proposed Dec-POMDP problem in a distributed way. We showed that our proposed client-server collaboration outperforms the state-of-the-art schemes in terms of QoE-efficiency, QoE-fairness, and social welfare by as much as 16%, 21%, and 24% respectively.

Lightsey, W. D. "Terminal transient for minimum-time dash mission". Thesis, Virginia Tech, 1987. http://hdl.handle.net/10919/44678.
Testo completoAbstract (sommario):
The terminal stage of a minimum-time mission of a high- performance aircraft is studied using both a reduced-order "energy" model formulation and a point-mass model formulation of the aircraft.
The mission is confined to vertical plane maneuvers, and is defined as consisting of three stages; a climb to the dash point,a steady-state dash at the high velocity point, and finally, a terminal transient from the dash point to the final state. This terminal maneuver evolves outside of the flight envelope, rapidly decreasing altitude while increasing the velocity to values greater than the dash velocity. The velocity then decreases from this maximum value as required in order to meet the final state specification.
Some of the trajectories that are generated during this terminal transient maneuver experience dynamic pressures that will exceed the dynamic pressure limit unless a constraint is placed on the state variables. Because of the need for enforcing this state constraint, a direct adjoining method for handling state constraints in the optimal control problem is studied. A numerical example is given to demonstrate the application of this method of handling state constraints for the case of the dynamic pressure limit.Finally, trajectories are generated that lead from the dash point to a uÌ nal state having lower altitude and energy values than those of the dash point, and observations are made concerning the characteristics of these maneuvers.

Testo completoAbstract (sommario):
The problem of determining cruise-dash trajectories is examined for the case of time-fuel optimization using a linear combination of time and fuel as the performance index. These trajectories consist of a transient arc followed by a steady-state arc. For cases where the steady-state arc is flown with full throttle the associated skeletal transient trajectories are also flown with full throttle, and approach the cruise-dash points monotonically in an asymptotic fashion.
When the steady-state arc is flown at an intermediate throttle setting, the transient trajectories follow a singular control law and exhibit a complex structure that is different from the full-throttle transients. Singular transients in the vicinity of singular cruise-dash points are confined to a bounded singular surface. In state-space these trajectories trace out asymptotic spirals on the singular surface as they approach the steady-state arc. If the initial operating point lies outside the singular surface, then the transient trajectories are composites consisting of a full-throttle or zero-throttle segment flown until the singular surface is met, followed by a singular segment that fairs into the cruise-dash point.
Addressing the question of optimality of the steady-state arc, it was found that although steady-state cruise fails a Jacobi-type condition, steady-state cruise-dash can satisfy this condition if the emphasis on time is sufficiently large. The outcome of the Jacobi-type test appears to be connected with the eigenstructure of the linearized state-adjoint system.PH. D.

Testo completoAbstract (sommario):
In this report I summarize the thesis, which is about to check what will happen if you decide to increase the interval between the a-checks, carried out on the Norwegian airline Widerøe. They want to know if an increase in time between the checks can give them an opportunity of increasing their aircraft fleet. In the current situation Widerøe has 11 Dash 8 Q400 and can consider a possible increase of 3 planes. This would be done without the need to increase accessibility of the hangars and increase in staff. What determines how often a check is performed is the maintenance tasks which has the shortest maintenance interval. On the Dash 8 the shortest interval is 600 flight hours. Therefore, a check must be performed once every 600 flight hour. But since there is so many maintenance tasks that will be performed at every check point, Widerøe have decided to divide their checks. They do this by dividing every check-package into four smaller packages. With this layout they get a breakdown of 150 flight hours instead of 600, and so you get less time between maintenance and fewer maintenance tasks at each occasion. My work started by developing a new checking package of 600 flight hours of interval. I did this by merging the existing check-package of 150 flight hour intervals into a checking package with 600-hour intervals. After that, it took considerable amount of work to define the differences between the various check packages. I started to count on whether you saved or not saved time by lengthening the interval. After that I optimized the number of technicians needed at each check and then calculated the total time required for each check. In the end I came up with two possible solutions. The first option is to use my check program with 600 flight hours of interval, and then increase the fleet with two aircrafts. The second option is to use a checking program with 300 flight hours of interval and then increase the fleet with one aircraft.I den här rapporten redovisas det examensarbete som jag utfört för flygbolaget Widerøe. Arbetet går ut på att kontrollera vad som sker då man väljer att öka planeringsintervallet på a-checkar. Flygbolaget önskar få svar på om en ökning av intervallet mellan checktillfällena kan leda till en möjlighet att öka flottan. I dagsläget har man 11 st. Dash 8 Q400 och ser en möjlig ökning med upp till 3 plan. Den ökningen ska vara möjlig utan att man behöver öka hangartillgången eller bemanningen. Det som bestämmer hur ofta en check skall utföras är de underhållsuppgifter som har kortast underhållsintervall. På Dash 8 är det kortaste intervallet 600 flygtimmar. Således bör en check utföras en gång varje 600 flygtimme. Men då det är relativt många underhållsuppgifter som kommer att utföras vid varje checktillfälle har man valt att dela upp arbetet. Det har man gjort genom att dela varje checkpaket i fyra mindre paket. Det gör att man får en uppdelning om 150 flygtimmar istället för 600, samt att man får kortare tid mellan varje underhållstillfälle, och vid varje tillfälle färre underhållsuppgifter. Uppgiften startade med att ta fram ett nytt checkpaket med 600 flygtimmars intervall. Det gjorde jag genom att det befintliga checkpaketet med 150 flygtimmars intervall lades ihop till ett checkpaket med 600 timmars intervall. Efter det krävdes ett omfattande arbete för att definiera skillnader mellan de olika checkpaketen. Jag började med att räknade på om man sparade eller inte sparade tid genom att förlänga intervallet. Efter det optimerade jag hur många tekniker som skulle behövas vid varje checkutförande för att sedan räkna ut den totala tidsåtgången för varje check. Jag kom fram till två möjliga lösningar. Det första alternativet är att använda ett Checkprogram på 600 flygtimmars intervall och då öka flottan med två flygplan. Det andra alternativet är använda sig av ett checkprogram på 300FH och öka flottan med ett plan.

Testo completoAbstract (sommario):
The method of singular-perturbation analysis is applied to the determination of range-fuel-time optimal aircraft trajectories.
The problem is shown to break down into three sub-problems which are studied separately. In particular, the inner layer containing the altitude path-angle dynamics is analyzed in detail. The outer solutions are discussed in an earlier work.
As a step forward in solving the ensuing nonlinear two-point boundary-value problem, linearization of the equations is suggested. Conditions for the stability of the linearized boundary-layer equations are discussed. Also, the question of parameter selection to fit the solution to the split boundary conditions is resolved. Generation of feedback laws for the angle-of-attack from the linear analysis is discussed.
Finally, the techniques discussed are applied to a numerical example of a missile. The linearized feedback solution is compared to the exact solution obtained using a multiple shooting method.Master of Science

Testo completoAbstract (sommario):
La diffusione di dispositivi che permettessero agli utenti di essere sempre connessi e che permettesse loro di scambiare informazioni ha conosciuto un'enorme diffusione in questo ultimo decennio. Analizzando il traffico della rete si puo' notare che la piu' grande fetta di dati che vi transitano appartiene ai contenuti multimediali, ovvero lo Streaming di contenuti audio e video. Sempre piu' servizi nascono per fornire agli utenti contenuti in abbonamento o fruibili ovunque essi siano. Se inizialmente la sfida era incentrata piu' sui contenuti, oggi si basa principalmente sulla qualita' dei contenuti stessi: si sono susseguiti quindi numerosi studi per migliorare le tecniche di condivisione e migliorare la Quality Of Experience (QoE) per l'utente mediante l'uso dei cosiddetti algoritmi di rate adaptation. Il lavoro svolto in questi studi si e' concentrato inizialmente sull'analisi e lo sviluppo di alcuni nuovi algoritmi di rate adaptation che si basano sull'ipotesi di conoscere a priori informazioni aggiuntive sui pacchetti che saranno successivamente scaricati per fruire del contenuto. In seconda battuta si e' voluto implementare un nuovo algoritmo che li potesse affiancare migliorando la QoE nel monitorare lo stato della connessione.
Si e' quindi implementato un simulatore scritto in Python che potesse fornire le informazioni di testing da utilizzare per le analisi.
La tesi si suddivide in quattro capitoli: nel primo vengono introdotti gli argomenti e definisce la terminologia utilizzata nel corso di questi studi; il secondo presenta lo stato degli studi compiuti nel campo dello streaming adattivo e vengono introdotti i concetti principali della tesi. Nel terzo vengono analizzate le caratteristiche tecniche del simulatore e presentati gli algoritmi sviluppati. Nel quarto ed ultimo capitolo vengono presentati e analizzati i dati raccolti .

Testo completoAbstract (sommario):
The delivery of video content over the internet has surged and internet video consumption has taken over the top spot in bandwidth usage. With this boom and the improvement in the quality of videos, the need for adequate delivery and data compression pushed the world for technological advances to sustain that usage. Dynamic Adaptive Streaming over HTTP (DASH) emerged as a leading choice and the standard for the delivery of video segments that are in line and conformable to the network conditions of the end users. The cloud was able to facilitate streaming by offering the resources and the storage when needed. Nevertheless, there were still problems that needed to be addressed such as latency, distribution and energy consumption. Fog computing is suggested as the solution for these problems as it can be combined with DASH to provide a more reliable and seamless stream. The combination aims to distribute the video segments over the fog nodes, allowing for a faster delivery and an efficient system. This is evaluated through a series of simulation that measure various aspects of the system. The results illustrate the feasibility and the potential of the proposed solutions.

Testo completoAbstract (sommario):
MPEG has been actively contributing towards the multimedia side in terms of storage and delivery of media content with flexible and advance file formats like the MPEG-2 transport stream and lately the MPEG 4 formats. Adaptive Streaming over HTTP is relatively a new genre in the area of streaming where this diverse content is delivered to TV’s, portable data units, smart phones, homes set top boxes etc. Most common of these streaming in practice are the apple live streaming, Smooth Streaming by Microsoft, HTTP Adaptive streaming as per the 3GPP specifications and the MPEG specified Dynamic Adaptive streaming over HTTP- (DASH). The technology is based on intelligence at clients end to cope up with variable network conditions and optimize the performance in an automated fashion. As the DASH specification is being finalized measures are to be taken to define criteria that will ensure the validation of a DASH process. Rules and conditions specified in the specification need to be followed by the client and server interaction as well as the content that will actually constitute the streaming process. This conformance is necessary to ensure the properties defined for a streaming process to provide the best user experience and performance efficiency. In light of this an initiative in this area of conformance testing is required so that the future deployment and implementation of DASH has a baseline to follow. The initial outline lay out by MPEG and DASH is followed to formulate and later implement the rules for the interaction between the client and the server. Secondly the content used in streaming is also checked for properties and attributes mentioned in the MPD and the ones necessary for DASH process. These efforts will help define the criteria required for DASH validation as well as a ground work that can be extended for further work in this domain. In summary, the main tasks are - Development of last stage of the integrated software for MPD conformance stages (Java Script) - Formulation of Rules for Conformance from DASH specifications. - Extension to the existing Qualcomm DASH Reference software to support conformance test on media content level The thesis mainly concentrates on logs that are the result of conformance processing. The logs are analyzed to see the whether the condition specified are fulfilled or not. The process can be regarded as a ‘YES’ or ‘NO’ result indicating the fault/error that occurred.

Testo completoAbstract (sommario):
The method of singular perturbations is applied to the determination of the optimal range-fuel-time trajectory for an air-breathing missile. This method is shown to lead to the reduced-order "cruise-dash" model, and this model is used in the optimization study. Earlier work in this area is extended by the inclusion of two not heretofore considered limits on the dynamical system.
The results of the earlier work are shown to hold throughout much of the velocity regime in which the missile operates, but operation in the very high and very low velocity ranges is shown to be sharply curtailed, with the optimal operating points being changed drastically in some cases. Also, the effect of the non-zero minimum admissible throttle setting and the resultant throttle-chattering on the solution of the control problem is examined in some detail.M.S.

Cette thèse porte sur la conception et la fabrication d'émetteurs optiques intégrés à base de ce matériau et de leur implémentation dans des systèmes de communication. La première partie de ce travail analyse les propriétés de ces nanostructures, théorique et expérimentale. Elles sont utilisées comme matériau actif de lasers modulés directement en amplitude. Les propriétés dynamiques de ces lasers sont ensuite évaluées et des transmissions sur fibre optique entre 0 et 100 km sont ensuite démontrées en utilisant un filtre étalon permettant d’augmenter en particulier le taux d’extinction dynamique. En s’appuyant sur cette démonstration basée sur des éléments discrets, une version monolithique intégrant un laser et un résonateur en anneaux a été réalisée. La dernière partie de ce travail porte sur des lasers à blocage de mode à base de ce matériau et en particulier sur les méthodes d’intégration sur substrat InP. En particulier, un design de miroir de Bragg innovant a été développé à cet effet et une démonstration d'un laser a blocage de mode intégré avec un amplificateur optique à semi-conducteur a finalement été réaliséeThis PhD dissertation presents a study on the properties of the novel quantum dash nanostructures and their properties for application in optical telecommunications. Over the last decade, scientific community has gained considerable interest over these nanostructures and several demonstrations have been made on their interesting optical and electronic properties, notably owing to their strong quantum confinement. This dissertation focuses on conception, fabrication and system demonstration of integrated optical transmitters based on quantum dash material. A first part of this work analyses the properties of qdashes theoretically and experimentally for their use as an active material in directly modulated lasers. The dynamic properties of this material are then evaluated leading to an optical transmission distances in range of 0-100km under direct modulation. The transmission is particularly studied with a passive optical filter to enhance the dynamic extinction ratio, the use of such passive filters is studied in detail. An innovative and fully integrated optical transmitter is finally demonstrated by integrating a ring-resonator filter to a distributed feedback laser. The second part of this work focuses on mode locked lasers based on this material and in particular the methods of integration of such devices on InP are explored. Thus an innovative Bragg mirror design is developed leading to a mode locked laser integrated with a semiconductor optical amplifier

Ce travail se concentre sur la déformation (cinématique et vitesse de glissement) le long de la faille de Dasht-e Bayaz. Nos résultats indiquent une direction de compression de N133°E pour l’état de contrainte ancien et N45°E pour l’état de contrainte moderne. Nos estimations la vitesse moyenne de glissement de cette faille en combinant des âges de cônes alluviaux déterminés à partir de l’analyse de nucléides cosmogéniques et la reconstruction morphotectonique des cônes alluviaux qui ont été décalés par cette faille, ont mené à un taux de ~1 mm / an. D’après notre discussion géodynamique, le cisaillement d’orientation N-S, responsable de l’accommodation de la convergence à l’Est de l’Iran, s’interrompt à la latitude de 34°N et ne se continue pas vers le Nord. Au Nord de cette latitude le système décrochant est remplacé par un mécanisme chevauchement / inverses, qui se transforme à la latitude ~36°N en cisaillement d’orientation NNW. Nous avons proposé le fait que dans le Nord of 34°N, la convergence est principalement accommodée par du raccourcissement crustal qui se traduit par des systèmes de failles inverses. Dans ce contexte, au NE de l’Iran, la convergence est majoritairement absorbée par du raccourcissement crustal pur le long des failles inverses, alors que les failles sénestres d’orientation E-W qui se situent entre les failles inverses tels que Ferdows et Jangal ont un rôle secondaire dans l’accommodation de la convergence. Ce scenario est confirmé par le faible taux de la vitesse de glissement qui a été obtenu pour la faille de Dasht-e Bayaz, et qui minimise le rôle de cette dernière dans l’accommodation de la convergence à l’échelle de la tectonique des plaquesThis dissertation focuses on two aspects of brittle deformation (kinematics and rate of movement) along the Dasht-e Bayaz fault. We applied the inversion technique to both kinds of seismologic and geological fault slip data gathered around the Dasht-e Bayaz fault. The inversion results indicate a mean N045°E trending horizontal σ1 for the modern stress field. The paleostress state is characterized by a homogeneous N133°E trending mean σ1, with a compressional stress regime, which shows that E-W faults of this region like Dasht-e Bayaz has been right-lateral in certain periods of their activity. The morphotectonic studies complemented by CRE dating of abandoned Quaternary fans offset by the fault allowed determining the slip rate of the Dasht-e Bayaz fault as ~1 mm / year. In view of our tectonic model, the right-lateral shear between the iranian plateau and fixed Eurasia is interrupted between 34°N and 36°N and is replaced by reverse/thrust faulting before being accommodated, farther north, by dextral faulting along NNW faults of the Kopeh Dagh. In this domain the convergence is mainly accommodated through NW-striking reverse/thrust faults. In this context, the E-W sinistral faults such as the Dasht-e Bayaz fault, being situated between NW striking reverse/thrust faults of Ferdows and Jangal, playing their secondary role in the accommodation of convergence. The different tectonic role of the Dasht-e Bayaz fault with respect to the Doruneh fault is confirmed by their meaningful different rates of slip such that the Doruneh Fault slips, at least, five times faster than the Dasht-e Bayaz fault

Testo completoAbstract (sommario):
Background: Patient Reported Outcome Measures (PROMs) are an important part of the assessment and treatment of shoulder pain. The Disability of Arm, Shoulder and Hand (DASH)/Quick-DASH and the Shoulder Pain and Disability Index (SPADI) are the most commonly used shoulder region PROMs and the original English versions have excellent measurement properties (validity, reliability and responsiveness). They have been translated into multiple languages but have not been available in Nepali. The Patient-Specific Functional Scale (PSFS) is a more general outcome measure but can also be used in shoulder assessment. It was available in Nepali, but its measurement properties had not been tested in shoulder pain patients. Therefore, the main aim of this thesis was to translate the DASH/Quick-DASH and the SPADI into Nepali and to study their measurement properties. Secondary aims were to test the measurement properties of the Nepali PSFS in shoulder pain patients and to compare performance of the Nepali DASH/Quick-DASH, SPADI and the PSFS.
Method: Translations of the PROMs into Nepali followed international standard guidelines and measurement properties of all four PROMs were tested using the COnsensus based Standards for the selections of health Measurement Instruments (COSMIN) checklist. Comparison of the PROMs was made on the basis of measurement properties and participant’s feedback.
Results: Significant adaptations during the translation process such as changing measurement units, activities and terminology were incorporated to improve cultural relevance of the Nepali SPADI and DASH questionnaires. The measurement properties testing was acceptable with excellent validity, reliability of the DASH/Quick-DASH and SPADI. The PSFS was the most responsive outcome measure. The scoring scale of the DASH/Quick-DASH was favoured by participants.
Conclusion: Four valid, reliable, and responsive shoulder PROMs are now available in Nepali for both clinical and research purposes. Combined use of the SPADI or Quick-DASH with the PSFS would be recommended to provide a balanced assessment of self-reported symptoms.

Streaming multimedia over the Internet is omnipresent but still in its infancy, specifically when it comes to theadaptation based on bandwidth/throughput measurements, clients competing for limited/shared bandwidth, and thepresence of a caching infrastructure. Nowadays the streaming infrastructure is existing over-the-top (OTT).Interestingly, these services are all delivered over-the-top of the existing networking infrastructure using the HypertextTransfer Protocol (HTTP) which resulted in the standardization of MPEG Dynamic Adaptive Streaming over HTTP(DASH).Video traffic is over 80% of the total internet traffic. Since Dynamic adaptive streaming over HTTP hasemerged it has a popular technique for video streaming on the internet. DASH allows the video player to adapt thebitrate according to the network conditions. DASH streaming client receives a manifest file, downloaded the referredvideo segments over HTTP, and play them back seamlessly emulated video streaming. This introduces latency of atleast one segment duration which decreases the quality of the user experience. In order to improve users over allQuality of Experience(QoE) a large number of adaptaion schemes were introduced to DASH.With such an importance of QoE on DASH, this thesis work investigates user acceptability of different DASHplayers. These players are exposed to different network conditions and the user analysis is given for each of thestreaming dash video for each player. The results of this thesis work include the analysis of the user rating for threedifferent players (Dash.js, GPAC and Shaka). The conclusion of this thesis is given by the quality of experience of thevideo streaming by the users which concludes that the Shaka player is preferred by the users compared to the othertwo players.

Testo completoAbstract (sommario):
Recent advancement in cameras and image processing technology has generated a paradigm shift from traditional 2D and 3D video to Multi-view Video (MVV) technology, while at the same time improving video quality and compression through standards such as High Efficiency video Coding (HEVC). In multi-view, cameras are placed in predetermined positions to capture the video from various views. Delivering such views with high quality over the Internet is a challenging prospect, as MVV traffic is several times larger than traditional video since it consists of multiple video sequences each captured from a different angle, requiring more bandwidth than single view video to transmit MVV. Also, the Internet is known to be prone to packet loss, delay, and bandwidth variation, which adversely affects MVV transmission. Another challenge is that end users’ devices have different capabilities in terms of computing power, display, and access link capacity, requiring MVV to be adapted to each user’s context. In this paper, we propose an HEVC Multi-View system using Dynamic Adaptive Streaming over HTTP (DASH) to overcome the above mentioned challenges. Our system uses an adaptive mechanism to adjust the video bitrate to the variations of bandwidth in best effort networks. We also propose a novel scalable way for the Multi-view video and Depth (MVD) content for 3D video in terms of the number of transmitted views. Our objective measurements show that our method of transmitting MVV content can maximize the perceptual quality of virtual views after the rendering and hence increase the user’s quality of experience.

O consumo de multimídia pela web tem crescido fortemente ao longo dos últimos anos. Com isso surge a preocupação do consumo de banda, que é significativamente reforçada pelo aumento da utilização da computação móvel. É fato conhecido que o consumo de banda para a multimídia ultrapassou o consumo nas redes P2P, e tende ao crescimento nos próximos anos. Nesse cenário, as tecnologias de streaming multimídia via HTTP vieram como parte da solução do problema de maior demanda de tráfego de multimídia. O MPEG-DASH é uma dessas tecnologias, e atualmente é utilizada em grande parte por grandes corporações que distribuem multimídia, como por exemplo Google e Netflix. No entanto, o processo da criação das mídias no padrão MPEG-DASH é um processo trabalhoso e de pouca documentação. O presente trabalho apresenta técnicas para transcodificação, segmentação e reprodução de mídias no padrão MPEG-DASH. As mídias convertidas são parte do material didático produzido pelo Centro de Educação a Distância da Universidade Federal de Juiz de Fora. O estudo foca no processo técnico de padronização das mídias para MPEG-DASH, dá foco aos problemas encontrados, além de analisar aspectos da reprodução das mídias. A dissertação traz também um estudo de caso, e análise de aspectos relevantes relacionados ao ambiente computacional da pesquisa. Foram testadas diversas técnicas e ferramentas, e os problemas, soluções e sugestões de uso são relatados ao longo do trabalho. Os resultados mostram que os resultados, apesar de problemas pontuais, são viáveis e benéficos para o consumidor do conjunto de mídias apresentado.
The multimedia consumption over the world wide web has been strongly growing along the last years. Hence it comes concerns about the bandwidth consumption, bolstered by significant raise of mobile computing. It is a known fact that multimedia bandwidth exceeded P2P network in terms of bandwidth consumption, and tend to grow in the next years. In this scenario, HTTP multimedia streaming technology came as a part of solution to the increasing multimedia bandwidth demand. MPEG-DASH is one of those technologies, currently employed at big distributing multimedia corporations, like Google and Netflix. However, the media transcoding and segmentation to MPEG-DASH standard is a laborious process and still slightly documented. This work cover in details techniques to media transcoding, segmentation, and reproduction on MPEG-DASH standard. The converted media are part of Centro de Educação a Distância of Universidade Federal de Juiz de Fora produced courseware. The work aims at technical process of MPEG DASH media standardization, with focus on raised problems, and includes some aspects of media reproduction. This work brings a case study, and an analysis of applicable aspects of computing environment. Were tested several techniques and tools and the problems, solutions and suggestions are reported through the work. Results shows that the results, although few problems, are viable and advantageous to consumer of the specified media set.

Abstract As the government promotes its community building policy, the Dahshi traditional street district began a series of renovation plans. The underlying principles of community building projects are combining and cooperation of the administration, professionals, and citizens to realize a bottom-up participatory planning and strengthening the awareness of citizenship. This research focuses on examining whether these assumptions are true in real situation. Thus, this research focuses on the interaction and power among government, professionals, and community organizations in the Dahshi traditional street district renovation. The research methods are data analysis and interview. The case study includes a software project and hardware plans. Four phases are discussed in each case, these are plan formation, planning process, budget allocation, and administrative compatibility, so as to analyze the participants’ interrelations and power distribution. The result of this research points out: that the government sector is the most powerful actor, the professionals act as the “executive manager” in government’s community building plans, the community organizations have less power because the government has controlled the planning and executing process, and the professionals direct the execution of the plan. Although the “community awareness” is the basic principle in theories and policies, in the real cases, the government still plays the most important role, and the participants can’t cooperate fully, with other participants not to mention following the democratic rules of community building.

The research studied about the outings for indigenous teaching carried out by Dashi Township Administration. The planning, the teaching process and the learning effect of the outings for third- to sixth-graders were studied. The purpose of this research tried to understand the activity effect, studied on the impact factors, and hoped to provide suggestions for activities held in the future. The evaluation criteria were formed by surveying the activity features referenced on related literatures. Then this research made inquiries by questionnaire, documental analysis, participant observation and interview methods. The conclusions of this research are: 1.The planning of the outings mostly introduces the organization resources in town and local cultural features spots. School faculties haven’t participate in the planning projects that the contents of the activity don’t associate with the curriculum of each grade. 2.The decision factors of the chosen routes and spots are: safety , convenience for parking ,pupils’physical endurance ,pupils’interest , the varieties of the scenic spots ,the representing of the scenic spots ,the properness of the time. We have made so many arrangements for the scenic spots that we don’t have enough time . 3.The contents taught by the professional narrators are clear and detailed. Yet the way be taught emphasizes on narration without the help of maps or any other teaching aids that pupils are lacked of instructing of imagination and feeling. 4.In cooperative teaching, the activity can’t build up pupils’ imagination due to teachers’ unfamiliar with the planning and contents of the activity. 「Observation notes or writing of what was learned」is the most common and thought to be the most proper evaluation tool. 5.In administration support, Dashi Township Administration can fully support on expenses, planning, administration affairs for the activity and make the best of the resources in town so that schools and teachers are willing to support on this activity. 6.In learning effect, outings for indigenous teaching can effectively improve the indigenous knowledge and identification scale for pupils. It’s a great help for the achievement of the indigenous education. Pupils have learned effectively in recognition and sentiment. Yet in technical learning, pupils are lack of which due to fewer activities. 7.The main factor that affects the cooperative teaching are 「the willingness, the burden of the responsibility」 and 「lack of time」of the teachers. 8.The activity would produce many kinds of problems and become a difficult situation due to too many pupils at the same time and fewer narrators. Although it maybe hard , a narrator assigned to a class of forth pupils should be properly arranged. 9.The proper outings should arrange teachers to be trained by professional narrator on the spot.

ABSTRACT The purpose of this thesis is to probe the public relationship between Tzuhu-Dashi Mausoleum Administration and the local residents. In this study, I made an inquiry about what people think or what people suggest to the administration in an effort to promote its service. There were 20 interviewees, including staff of the unit, legislators, visitors, local community residents, and some charity groups in the community. After analyzing the above material offered from the interviewees, I found some facts. The facts were as follows. 1. All the staff of the administration are willing to contribute to the success of public relationship. 2. All interviewees showed their positive attitude to the administration and also hope Taiwanese government can liberate some “restricted areas”, like “Back Tzuhu”-a natural lake. 3. Most services for visitors are prior to groups not for individuals. 4. The staff think they could offer more information and do better when they follow the government’s policy. 5. Poeople who never visited here feel the place majesty and mysterious. 6. The administration should be legalized, and is subordinated to Council for Cultural Affair, not National Defence. According to the above conclusions, I suggested: 1. The public relationship should be aggressively pushed. 2. Some information about Tzuhu-Dashi Mausoleum Administration should be disseminated by pluralistic way. 3. The administration should liberate some “restricted areas”, in order to offer local residents to enjoy more spacious environment. 4. Avoiding any misunderstandings between the administration and the local residents, the administration should tell the residents what it can do or what it can not do for them. 5. Have a good communication and relationship with the local residents. 6. The administration should communicate effectively with central government in order to obtain plentiful resources. Key Words: Tzuhu-Dashi Mausoleum Administration, public relationship, local residents

The self-evident Identity demonstrated in a region allows people to recognize the peculiarity of the environment, so as to distinguish its disparity from others. In recent years, the tourist development in Ancient Street has pushed each of them to a limit, in which the identical property would sooner or later perish their characteristics and let them face the loss of their specialties. Thus, the purpose of the present study is to identify the Dashi Ancient Street from the Sansia Ancient Street in terms of their respective property. Comparing the element of self-evident nature between the said two streets, we may learn the impact onto residents and tourists’ percipience, successively, it will help us able to propose a program to shape and maintain the Ancient Street’s environmental space. This study is selecting the element of Identity through a in-depth interview with residents and tourists, then, checking and analyzing the “Component elements of the Ancient Street”, “Cognizing factors to work upon Identity”, and “Identity”. We obtain total 983 copies of the effective questionnaire in a pilot survey, from which we divide the Identity into normal element and unique element. The survey findings show that the normal element is common to all Ancient Street, but the unique element exists only in a specific street. Residents and tourists’ different impression onto Ancient Street’s “Component elements of the Ancient Street”, “Cognizing factors to work upon Identity”, and “Identity” leads to a diverse influence while the“Component elements of the Ancient Street” and “Cognizing factors to work upon Identity” will also affect the cognizing level of the “Identity”. The two ancient streets have the normal element such as the “Building”, “Temple”, “Arcade”, and “Temple court” . Dashi Street‘s unique element includes the “Building” and “Human factor” and Sansia’s element comprises the “Exterior space unit” and the “Road and traffic”. This Study suggests that development of these areas shall highlight their characteristics, so as manifest the local uniqueness.
