Full textAbstract:
There are a growing number of mobile phones being used in developing contexts, such as Africa. A large percentage of these phones have the capability to take photographs and transmit them freely using Bluetooth. In order to provide people with media on their mobile phones public displays are becoming more common. Three problems with current public displays – cost, security and mobility – are discussed and system proposed that uses a mobile phone as a server. Media is displayed on specially designed paper posters, which users can photograph using their mobile phones. The resulting photographs are sent, via Bluetooth, to the server, which analyses them in order to locate a specially designed barcode, representing the media, which is then decoded and the requisite media returned to the user. Two barcoding systems are tested in laboratory conditions, and a binary system is found to perform best. The system is then deployed on a campus transportation system to test the effects of motion. The results show that the system is not yet ready for deployment on moving transport.

Full textAbstract:
Public use of the Internet increases as wideband connections become pervasive and applications suitable for media distribution grow popular. Group collaboration applications have attracted interest during recent years. Wireless connectivity and business applications also furthers a need for reliable communication protocols. Multicast is a driving force for new applications involving one-to-many as well as many-to-many user scenarios like lecturing, discussions, and collaborative work. In some applications guaranteed delivery of every packet is not crucial, while in other this is a requirement. Error handling in reliable protocols can present a substantial challenge already in a homogeneous environment. Including a plethora of end-user terminal types with widely varying resources it becomes even more challenging. Protocols and applications must therefore be able to handle receiver and network link heterogeneity. The thesis addresses some of the challenges facing the applications in this field, related to multicast and unicast alike. Although the obstacles each of them must overcome may differ, there are similarities with regards to possible solutions with respect to error handling or resource allocation. Error handling protocols are proactive or reactive. Proactive protocols transmit redundant information along with the original information, enabling the receivers to repair lost packets without feedback to the sender. Reactive protocols rely either on positive or negative feedback from the receivers in order to establish reliability. According to a definition of semantic reliability the reliability concept can be interpreted in terms of application semantics. It is proposed to view reliable multicast as a special case of semantically reliable multicast and to implement a dynamically configurable transport layer with an error-handling rule set that can be configured from the application or even from the sender in- session. It is also proposed to make use of the application's knowledge of specific semantics to improve on the recovery of lost packets, congestion handling, or resource allocation. The thesis also presents a bandwidth-sharing scheme for video in group collaboration using application semantics in the form of user hints. The presence of such events is made available to all senders via message passing between session members. As information relating to a user's interest in another user is conveyed, the sender may increase its use of resources on the expense of other senders. A scheme is proposed and a prototype implementation and experimental results are presented.<br><p>Godkänd; 2003; 20060918 (ysko)</p>

Full textAbstract:
Understanding the extent of microbial transport, distribution and activity in the subsurface is paramount for effective in-situ bioremediation. In one study, we investigated the impact a substrate pulse has on the movement of inoculated or indigenous bacteria through saturated porous media. In another study, we developed a method to visualize the distribution of bacteria on soil surfaces. The elution of either inoculated or indigenous bacteria was monitored from model (homogenous) sand or natural (heterogenous) soil column systems. Sand columns receiving salicylate resulted in enhanced elution of inoculated P. putida. However, the salicylate pulse did not result in enhanced elution of P. putida from a natural system. For natural heterogenous systems, the salicylate pulse significantly affected the elution of certain indigenous bacteria. Specifically, more heterotrophs were eluted from soil columns receiving salicylate than from those that did not for both loamy sand soils tested. On the other hand, there were consistently fewer salicylate-degrading cells eluted in the presence of salicylate from one of the two soils tested. These data suggest that bacterial transport is a function of both the porous medium and the microbial population(s) under investigation. In the second study, an agar lift-DNA/DNA hybridization technique was developed to visualize the distribution of eubacteria on soil surfaces. Briefly, a single layer of soil was lifted from the surface of soil microcosms onto agar slabs and allowed to incubate. Bacterial colonies were lifted from the agar slabs onto membranes. The location of individual colonies was detected on the membranes by hybridization with a probe complementary to a conserved region of the eubacterial genome. This method was able to detect active microorganisms on different soil surfaces. The probe signal correlated well with the number of metabolically active microorganisms found in soils amended with a carbon source. This technique also allowed for visualization of localized microbial activity. A combined approach utilizing both soil column studies and the agar-lift technique should allow researchers to better elucidate microbial transport, distribution and activity in subsurface environments.

Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2002.<br>Includes bibliographical references (p. 107-114).<br>This thesis embarks on distributing the distribution for real-time media, by developing a decentralized programmable protocol architecture. The core of the architecture is an adaptive application-level protocol which allows collaborative multicasting of real-time streams. The protocol provides transparent semantics for loosely coupled multipoint interactions. It allows aggregation and interleaving of data fetched simultaneously from diverse machines and supports the location and coordination of named data among peer nodes without additional knowledge of network topology. The dynamic stream aggregation scheme employed by the protocol solves the problem of network asymmetry that plagues residential broadband networks. In addition, the stateless nature of the protocol allows for fast fail-over and adaptation to departure of source nodes from the network, mitigating the reliability problems of end-user machines. We present and evaluate the algorithms employed by our protocol architecture and propose an economic model that can be used in real-world applications of peer-to-peer media distribution. With the combination of an adaptive collaborative protocol core and a reasonable economic model, we deliver an architecture that enables flexible and scalable real-time media distribution in a completely decentralized, serverless fashion.<br>by Dimitrios Christos Vyzovitis.<br>S.M.

Full textAbstract:
Developed from the practice of building an open source Peer-to-Peer (P2P) distribution system, this research begins by examining the potential forking (duplicating two copies as separate entities) of a software development project. This research begins with the exploration of the discourses of forking within Software Studies and Actor Network Theory, concluding that both offer a degree of insight, especially around power relations but that they both lack predictive and temporal qualities in order to model the emergent pattems arising from the development process. As an alternative view, the research considers the idea of forking as a software-borne process of speciation, where forking establishes a barrier to source-code flow much as a geographical barrier impedes genetic exchange in biology. Exploring the existing ideas and theories of applying an evolutionary model to the development of human technology it argues that these fall into two broad areas of concern. The first of these areas considers evolution as too narrow a mechanistic process and so fails to fully account for the role of human society and culture. The second of these areas uses biological evolution as a metaphorical construct and by doing so fails to establish any solid methodological framework beyond that proxy. The research adopts the position that to fully examine technology evolution, the discourse should involve examples of technology which encompass complex assemblages of culture and technology. The research cites media as an example of such as technology and P2P as a sub-set of a media technology. Responding to the concerns with existing concepts of technology evolution, the research draws on the practice of software development to arrive at a new methodology. This method begins with the position that P2P technology has many advantages as an object of study much as biologists study fruit flies for genetic research, where P2P is analogous to studying the genotype (genetic make-up) and phenotype (visual appearance) of a biological species. Building on this idea it then argues that the source code used to create software is a parallel of DNA in form and function. From this basis the research proposes how examining the layers of committed source code of software projects can be used to establish a common analytical framework. This method allows the data gathered from this process to depict proto-phylogenetic trees of different P2P projects, giving an insight into how software forking as a form of technology speciation. It concludes that there is a form of an evolutionary process occurring within software development and outlines a hypotheSiS as to how this form operates. This hypothesis proposes that the environment is the landscape conSisting of human culture and societies, whereas the individual organism here is the particular iteration of the technology and an evolutionary process is emergent from this interaction. It then explores some predictive uses of this hypothesis.

Full textAbstract:
Determination of the spatial distribution and quantification of concentration of pure beta- and photon-emitting radionuclides in absorbing media by external measurements is the subject of this study. Measurements of radiation and the operation of radiation detectors are based on the radiation interactions with matter and the theory governing these interactions has been discussed. Various techniques for localising pure beta- and photon-emitting radionuclides situated inside attenuating media have been suggested on a theoretical basis, and have been experimentally shown to work successfully. Most of the work is on single photon emission computed tomography (SPECT). The theory of mathematical reconstruction of a two dimensional distribution from its projections is discussed and reconstruction techniques and their relative merits and demerits have been reviewed. SPECT seeks the determination of absolute regional radionuclide concentrations as a function of time. A SPECT system has been developed by modifying an existing transmission CT scanner and the reconstruction algorithms. The performance of the SPECT system has been tested for a number of point sources and various extended sources in gas, liquid and solid forms. The SPECT scanner in its present design is capable of performing in both the transmission and emission modes. The characteristics of the SPECT scanner, including the detector efficiency, spatial resolution and the effect of collimator size, have been studied experimentally. The major problems faced by SPECT include the solid angle effect, which influences the collection efficiency, in scattered radiation, and attenuation of photons inside the surrounding medium. These problems together with their various possible solutions have been discussed in detail. Methods for compensation for solid angle variation, in scattered radiation and photon attenuation have been devised and used successfully to compensate the projection data.

Full textAbstract:
This thesis details the design and construction of an experiment to measure the radial distribution of laser gain in a cylindrical Helium-Neon laser gain tube. This distribution is important as it can effect the transverse mode structure of a running ring laser. Earlier theoretical models of the distribution were not supported by high quality experimental data and fail to take into account some physical processes. A resolution of 8 parts per million in gain and 50 μm in radial position has been achieved. Gain distributions have been measured and are shown to be well modeled by a 0th order Bessel function with first roots at the tube walls and a central dip depending on excitation power; except for the region very near to the tube walls where a very rapid increase in gain has been observed. Hydrogen has been identified by spectroscopic analysis as the primary constituent of gas contamination and cause of the long term reduction in gain of large ring lasers. Additional work has been done to detect a proposed non-classical Lense-Thirring field around a spinning lead superconductor. It was found that any effect is at least 20 times smaller than predicted. Techniques and tools for data acquisition programming have been reviewed focusing on difficulties with coupling of user interface and application logic, monolithicity, difficulties with scripting and algorithm implementation.

Full textAbstract:
This work presents the results of an experimental study of liquid distribution with counter-current gas flow and without gas flow, carried out in a 0.3m diameter and 1.5m long perspex column packed randomly with 1" plastic Pall rings, 1" plastic Intalox saddles, No.25 Intalox Metal Tower Packing(IMTP) and No.1 metal Nutter rings, in separate experimental sets. The measurements were carried out using concentric annular collectors, in order to measure the distribution of liquid and to distribute the gas uniformly across the bottom of the column. The column was operated with gas flowrates varying over the range of 0 to 1 kg/m<SUP>2</SUP>.sec, and liquid flowrates varying over the range of 40 to 80 1/min. Packing height was increased by adding successive layers of packing, while the ratio of the flow supplied to the bulk and wall regions was varied throughout the experiments. The experimental results were analyzed and compared to a theoretical model developed by Gunn(1978) and extended in 1991. Two regions of packing of different permeabilities may be distinguished, the bulk region and an annular region of packing adjacent to the wall and of higher permeability. The wall region was confined to the order of one particle diameter while the remaining cross-section of the column was accounted as the bulk region. The separation of volumetric mass transfer coefficients in packed columns into mass transfer coefficients and specific surface area, has been attempted using the available data on mass transfer presented by various investigators. One aim of this work is to provide a generalized correlation for mass transfer coefficients and interfacial area that characterized the mass transfer performance of various packings that may be used for designing or scaling up columns or reactors.

Several examples of nearly optimal transport networks can be found in nature. These networks effectively distribute and drain fluids throughout a medium. Evidence suggests that blood vessels of the circulatory system, airways in the lungs and veins of leaf venations are examples of networks that have evolved to become effective in their tasks while simultaneously being energy efficient. Hence, it does not come as a surprise that recent performance improvements of modern power generating devices occur due to the use of nature-inspired channel architectures. Guided by this observations, in this work, we investigate the application of visually realistic computer-generated leaf venation patterns to a type of photovoltaic device. We solve the flow through the device problem using Computational Fluid Dynamics (CFD) tools. Moreover, we attempt to develop experimentals models. Ultimately, we seek to single out the network properties that affect their performance.<br>Diversos exemplos de redes de transporte quase ótimas podem ser encontradas na natureza.

Dessa forma, não chega a ser surpreendente que recentes melhorias de performance em dispositivos de geração de energia modernos ocorrem devido ao uso de arquiteturas de canais inspiradas na natureza. Guiados por estas observações, nesse trabalho, investigamos a aplicação de padrões de venações verossímeis geradas por computador em um tipo de dispositivo fotovoltaico.

Full textAbstract:
IPTV is gaining increasing attention. It is an expanding field where a lot of people are working hard to solve the problems that delay its wide-spread use. One major problem is that the existing IPTV distribution mechanisms do not seem to work well when applied on a large scale. Especially, IP multicast does not seem to meet the requirements of highly demanding IPTV services. In contrast, peer-to-peer architectures for distributing content have been available for a number of years (since the late 1990’s), and their success suggests that this is a promising alternative means of distributing content. Although peer-to-peer architectures are well known for file transfer, this kind of architecture has been used in this thesis for distributing streaming video flows. We combine results from two different approaches - IPTV and peer-to-peer systems - as part of our design and implementation of a new solution for distributing IPTV. Our proposal aims to avoid any weaknesses that the existing solutions have, whilst offering a viable solution for distributing live content.<br>Intresset kring IPTV ökar hela tiden, och många människor arbetar på att lösa de problem som hindrar området från att växa snabbt. Ett av huvudproblemen är att den existerande IPTV-distributionstekniken inte fungerar bra då den appliceras på stora lösningar. Bland de största problemen är att IP-Multicast inte möter de krav som marknaden ställer på global distribution av material. I motsats till detta har peer-to-peer teknik, som funnits sedan 90-talet, visat sin styrka för fil distribution på en mycket global skala på existerande infrastruktur. I denna uppstats kombinerar vi dessa två områden för att utröna vilka möjligheterna som finns för att optimera kostnaden för distrubition av live-tv samtidigt som vi försöker att undvika de svagheter som normalt associeras med de olika arkitekturerna. Vårt mål är att utnyttja de bästa egenskaperna från de olika teknikerna för att skapa en livsduglig och långsiktig lösning för TV-distribution.

Full textAbstract:
This report will deal with the process of creating an example based procedural distribution tool. This is accomplished within the Frostbite game engine editor, FrostEd. By using actual placements of objects in the editor as in-data, the tool provides the artist with an unmatched visual feel for calibrating its properties and settings. Note that this is a unique technique and was invented during the creation of this tool. The tool is based on a machine learning approach. It creates a feature vector from the example placements for each type of object. These vectors are then used to create statistical models which in turn are used to generate new object placements. The process of determining the position and rotation when generating an object is divided into two parts. A new concept called Feature Function (FF) is utilized to provide each element in the population with a probability to obtain a certain position and rotation.

Full textAbstract:
This thesis presents a system for real-time large scale distributed music distribution, such as radio on the Internet. The existing technologies do not enable the full potential that broadcast media on the Internet can give, such as a very large number of interactive receivers. A technology that can help achieve potential is IP-multicast, which enables broadcast applications to scale to millions of receivers. However, IP-multicast creates new problems that have to be solved for it to be used on the Internet; some of these problems are addressed in this thesis. The system presented in this thesis, mIR - multicast Interactive Radio, has been used as a prototype to implement and examine different solutions to some of the issues of IP-multicast and real time music distribution. These are problems such as heterogeneity, reliability and security. Heterogeneity and reliability are different aspects of the same problem: that IP-multicast is an unreliable Internet transport mechanism. In this thesis different methods for avoiding these problems are described and evaluated. Security in the context of IP-multicast has many aspects. While the problems of confidentiality and authentication have been extensively examined, there are still a few unresolved problems. One of these problems is traitor tracing: how to know the origin of illegal copies of a media object such as a radio transmission. An application of digital watermarking, fingerprinting, can be used to distinguish between different copies of the same media object, but requires that each copy is individually marked. This contradicts the basic property of multicast that ensures its scalability: that everyone receives exactly the same data. We show how we can combine the different goals of fingerprinting and IP-multicast while still maintaining the scalability features of multicast.<br><p>Godkänd; 2001; 20070313 (ysko)</p>

Full textAbstract:
With the advancement of the Internet age, the need for more and more data distribution to different users on different types of networks in short time and at a nominal cost has also increased significantly. To achieve these objectives several technologies have been used with different sorts of implementations but only few survive in today’s very competitive financial market. The objective of our thesis is to study the technology and the financial market of the Content Distribution Network, which has up till now proven to be a very good and effective way to meet the always increasing demands of the rapidly developing Internet age. In this thesis, we will not only discuss the taxonomies of the Content Distribution Network or CDN, its different types and implementations but we will also focus on its financial issues and its performance in the financial market. The aim of our project is to study and understand the technology of the CDN, the problems related to its implementations, research work and its money matters.

With the massive deployment of broadband access to the end-users, the continuous improvement of the hardware capabilities of end devices and better video compression techniques, acceptable conditions have been met to unleash over-the-top bandwidth demanding and time-stringent P2P applications, as multiview real-time media distribution. Such applications enable the transmission of multiple views of the same scene, providing consumers with a more immersive visual experience. This thesis proposes an architecture to distribute multiview real-time media content using a hybrid DVB-T2, client-server and P2P paradigms, supported by an also novel QoS solution. The approach minimizes packet delay, inter-ISP traffic and traffic at the ISP core network, which are some of the main drawbacks of P2P networks, whilst still meeting stringent QoS demands. The proposed architecture uses DVB-T2 to distribute a self-contained and fully decodable base-layer video signal, assumed to be always available to the end-user, and an IP network to distribute in parallel - with increased delay - additional IP video streams. The result is a decoded video quality that adapts to individual end-user conditions and maximizes viewing experience. To achieve its target goal this architecture: defines new services for the ISP’s services network and new roles for the ISP core, edge and border routers; makes use of pure IP multicast transmission at the ISP’s core network, greatly minimizing bandwidth consumption; constructs a geographically contained P2P network that uses P2P application-level multicast trees to assist the distribution of the IP video streams at the ISP access networks, greatly reducing inter-ISP traffic, and; describes a novel QoS control architecture that takes advantage of the Internet resource over-provisioning techniques to meet stringent QoS demands in a scalable manner. The proposed architecture has been implemented in both real testbed implementation and ns-2 simulations. Results have shown a highly scalable P2P overlay construction algorithm with very fast computation of application-level multicast trees (in the order of milliseconds) and efficient reaction to peer-churn, with no perceptually annoying impairments noticed. Furthermore, huge bandwidth savings are achieved at the ISP core network, which considerably lower the management and investment costs in infrastructure. The QoS based results have also shown that the proposed approach effectively deploys a fast and scalable resource and admission control mechanism, greatly minimizing QoS related signalling events by using a per-class over-provisioning approach and thus preventing per-flow QoS reservation signalling messages. Moreover, the QoS control architecture is aware of network link resources in real-time and supports for service differentiation and network convergence by guaranteeing that each admitted traffic flow receives the contracted QoS. Finally, the proposed Scalable Architecture for Multiview Real-Time Media Distribution for Next Generation Networks, as a component for a large project demonstrator, has been evaluated by an independent panel of experts following ITU recommendations, obtaining an excellent evaluation as computed by Mean Opinion Score.

Full textAbstract:
Liquid chromatography is an essential technique in manufacturing biopharmaceuticals where it is used on all scales from analytical applications in R&D to full-scale production. In chromatography the target molecule, typically a protein, is separated and purified from other components and contaminants. Separation is based on different affinities of different molecules for the chromatographic medium and the physical and chemical properties of the latter determine the outcome. Controlling and designing those properties demand efficient analytical techniques. In this thesis the approach was to develop characterization methods based on nuclear magnetic resonance (NMR) spectroscopy for the assessment of various important physico-chemical properties. The rationale behind this strategy was that the versatility of NMR – with its chemical and isotopic specificity, high dynamic range, and direct proportionality between the integral intensity of the NMR signal and the concentration of spin-bearing atomic nuclei (e.g., 1H, 13C, 31P and 15N) – often renders it a very good choice for both qualitative and quantitative evaluations. These characteristics of NMR enabled us to develop two quantification methods for chromatography-media ligands, the functional groups that provide the specific interactions for the molecules being separated. Furthermore, a new method for measuring the distribution of macromolecules between the porous chromatographic beads and the surrounding liquid was established. The method, which we have named size-exclusion quantification (SEQ) NMR, utilizes the fact that it is possible to assess molecular size distribution from corresponding distribution of the molecular self-diffusion coefficient where the latter is accessible by NMR. SEQ-NMR results can also be interpreted in terms of pore-size distribution within suitable models. Finally, we studied self-diffusion of small molecules inside the pores of chromatographic beads. The results provided new insights into what affects the mass transport in such systems. The methods presented in this thesis are accurate, precise, and in many aspects better than conventional ones in terms of speed, sample consumption, and potential for automation. They are thus important tools that can assist a better understanding of the structure and function of chromatography media. In the long run, the results in this project may lead, via better chromatographic products, to better drugs and improved health.<br>Vätskekromatografi är en viktig teknik för tillverkning av biologiska läkemedel och används för alltifrån småskaliga analytiska applikationer till fullskalig produktion. I kromatografi separeras och renas målmolekylen (oftast ett protein), från andra komponenter och föroreningar genom att utnyttja molekylernas olika affinitet för det kromatografiska mediumet, vars fysikaliska och kemiska egenskaper har stor betydelse för hur separationen fungerar. För att kunna kontrollera och designa dessa egenskaper krävs effektiva analysmetoder. Strategin i den här avhandlingen var att utveckla metoder baserade på kärnmagnetisk resonans (NMR) spektroskopi för att karaktärisera flera viktiga fysikalisk-kemiska egenskaper. Anledningen till denna strategi är att mångsidigheten hos NMR – med dess kemiska och isotopiska specificitet, stora dynamiska omfång och direkta proportionalitet mellan NMR-signalens integralintensitet och koncentrationen av spinnbärande atomkärnor (t.ex. 1H, 13C, 31P och 15N) - ofta gör den till det bästa valet för både kvalitativa och kvantitativa tillämpningar. Dessa egenskaper hos NMR gjorde att vi kunde utveckla två kvantifieringsmetoder för kromatografimedia-ligander, dvs de funktionella grupperna som ger de specifika interaktioner som gör att molekylerna kan separeras. Dessutom har en ny metod för att mäta fördelningen av makromolekyler mellan de porösa kromatografiska pärlorna och den omgivande vätskan tagits fram. Metoden, som vi har valt att kalla size-exclusion quantification (SEQ) NMR, utnyttjar det faktum att det är möjligt att mäta molekylstorleksfördelningen genom att mäta motsvarande fördelning av självdiffusionskoefficienter, där den sistnämnda kan bestämmas med NMR. Resultaten från SEQ-NMR kan tolkas i termer av porstorleksfördelningar genom att använda lämpliga modeller. Slutligen studerade vi självdiffusion av små molekyler inuti porerna i kromatografiska pärlor. Resultaten gav nya insikter om vad som påverkar masstransporten i sådana system. De metoder som presenteras i denna avhandling är noggranna, precisa och på många sätt bättre än konventionella metoder när det gäller hastighet, låg provförbrukning och automatiseringspotential. De nya metoderna är därför viktiga verktyg som kan hjälpa till att ge en bättre förståelse av struktur och funktion hos kromatografimedia. I det långa loppet kan resultat från det här projektet kunna bidra till effektivare kromatografiska produkter, vilket i slutändan kan leda till bättre läkemedel och hälsa.<br><p>QC 20170403</p>

Thesis (MScEng)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: The way in which people consume video is changing with the adoption of
new technologies such as tablet computers and smart televisions. These new
technologies, along with the Internet, are moving video distribution away from
satellite and terrestrial broadcast to distribution over the Internet. Services
online now offer the same content that originally was only available on satellite
broadcast television. However, these services are only viable in countries with
high speed, inexpensive Internet bandwidth. The need therefore exists for
alternative services to deliver content in countries where bandwidth is still
expensive and slow. These include many of the developing nations of Africa.
In this thesis we design and develop a video distribution platform that
relies on peer-to-peer networking to deliver high quality video content. We use
an existing video streaming peer-to-peer protocol as the primary distribution
mechanism, but allow users to share video over other protocols and services.
These can include BitTorrent, DC++ and users sharing hard drives with one
another. In order to protect the video content, we design and implement a
security scheme that prevents users from pirating video content, while allowing easy distribution of video data. The core of the security scheme requires a low
bandwidth Internet connection to a server that streams keys to unlock the
video content. The project also includes the development of a custom video
player application to integrate with the security scheme.
The platform is not limited to, but is aimed at high speed local area networks
where bandwidth is free. In order for the platform to support feasible
business models, we provision additional services, such as video cataloging
and search, video usage monitoring and platform administration. The thesis
includes a literature study on techniques and solutions to secure video entertainment,
specifically in a peer-to-peer environment.<br>AFRIKAANSE OPSOMMING: Die wyse waarvolgens mense video verbruik is aan die verander met die ingebruikneming
van nuwe tegnologie soos tabletrekenaars en slim televisiestelle.
Hierdie nuwe tegnologie tesame met die Internet maak dat die verspreiding
van video al hoe minder plaasvind deur middel van satellietuitsendings en al
hoe meer versprei word deur die Internet. Aanlyn-Internetdienste bied deesdae
dieselfde inhoud aan as wat voorheen slegs deur beeldsending versprei is.
Hierdie dienste is egter slegs lewensvatbaar in lande met hoëspoed- en goedkoop
Internetbandwydte. Daar is dus ’n behoefte aan alternatiewe tot hierdie
dienste in lande waar bandwydte steeds duur en stadig is. Baie lande in Afrika
kan in hierdie kategorie ingesluit word.
In hierdie tesis word ’n videoverspreidingsplatform ontwerp en ontwikkel,
wat van portuurnetwerke gebruik maak om hoëkwaliteit-beeldmateriaal te versprei.
Die stelsel gebruik ’n bestaande portuurnetwerk-datavloeiprotokol as
die premêre verspreidingsmeganisme, maar laat gebruikers ook toe om videoinhoud
direk met ander gebruikers en dienste te deel. BitTorrent, DC++ en
gebruikers wat hardeskywe met mekaar deel word hierby ingesluit. Ten einde die videoinhoud te beskerm ontwerp en implimenteer ons ’n sekuriteitstelsel
wat verhoed dat gebruikers die videoinhoud onregmatig kan toe-eien, maar
wat terselfdertyd die verspreiding van die data vergemaklik. Hierdie sluit die
ontwikkeling van ’n pasgemaakte videospeler in. Die kern van die sekuriteitstelsel
benodig ’n lae-bandwydte-Internetverbinding na ’n bediener wat sleutels
uitsaai om die videoinhoud te ontsluit.
Alhoewel nie daartoe beperk nie, is die platform gemik op hoëspoed-plaaslikegebiedsnetwerke
met gratis bandwydte. Om die platvorm aan ’n haalbare
sakemodel te laat voldoen het ons vir addisionele dienste soos videokatalogisering
met soekfunksies, videoverbruikersmonitering en platvormadministrasie
voorsiening gemaak. Die tesis sluit ’n literatuurstudie oor tegnieke en oplossings
vir die beskerming van video data, spesifiek in die portuurnetwerke
omgeving, in.

Full textAbstract:
The effect of reduced gravity on the balanced management of liquid, gaseous and ionic fluxes in unsaturated porous media remains a central challenge for plant-based bio-regenerative life support systems needed for long-duration space missions. This research investigated how shifting capillary and gravitational forces alter the sample-scale transport and distribution of fluids in mm-sized porous ceramic aggregates. Measurements in variably saturated media conducted on the International Space Station in microgravity ($sim1cdot10^{-3} g_{earth}$) and measurements during parabolic flight in variable gravity encompassing microgravity, terrestrial gravity and hypergravity ($sim1.8 g_{earth}$) were supported by numerical modeling based on fundamental, earth-derived soil-physical relationships. Measurements of water fluxes in rigid saturated media suggested Darcian flow unaffected by gravity. Observations of hydraulic potential and sample water content were used to estimate the primary draining and wetting water-retention characteristic (WRC). Terrestrial parameterizations of the WRC were largely unaffected by reduced gravity. However, because the WRC is hysteretic, heterogenous water-content distributions resulted within the confines of the primary draining and wetting characteristics. Ensuing distributions were fundamentally different from terrestrial observations and were stable in the absence of a significant gravity gradient. We showed that these distributions, though unexpected, could be predicted using the Richards equation. One consequence of altered water distribution could be the reduction in, and increased tortuosity of, continuous gas-filled pathways for diffusive transport compared to terrestrial estimates. Measurements of oxygen diffusion in microgravity suggested reduced diffusivities during draining. These observations, particularly for the smaller particle-sized media, were suggestive of the delayed formation of critical air-filled pathways at lower water contents. This dissertation further uses a case history of a stratified root-zone developed based on water-retention characteristics of different particle-sized media. The root-zone design provided a more uniform water-content distribution at terrestrial gravity suggested to provide more optimal conditions for root growth. Additionally, the design and testing of a novel integrated sensor for measurements of water content based on the dissipation of heat and estimation of nutrient status based on electrical resistivity are discussed. These results should provide insights into microgravity fluid distribution and transport contributing to the design and implementation of controllable plant-growth systems for use in microgravity and future planetary habitats.

Full textAbstract:
In 2011, home-video distribution company, The Criterion Collection, teamed up with streaming-content provider Hulu, extending their business model to include online streaming to subscribers through Hulu Plus. With the rise of Over-The-Top (OTT) media distribution services into the at-home market, the question that Criterion now faces is: how will the company survive as the market shifts away from Criterion’s established values? And, more pertinently, how does Criterion, by rebranding their image to compete in the streaming market, hope to attract new users without alienating their established fan base or sacrificing their brand identity? This thesis examines the Criterion Collection’s brand identity, business model, and history, focusing on its packaging and promotion, distribution channels (physical and streaming), and the formation of a self-established cinephile community through their website, Criterion.com. In my examination of Criterion’s attempts to branch out into new markets and adapt to alternative modes of media consumption, I argue that Criterion is taking strides to attract new audiences and build a tightly knit online fan community around their brand.

Full textAbstract:
Les méthodes expérimentales utilisées actuellement pour déterminer la distribution de taille des pores (DTP) dans les milieux poreux présentent des inconvénients, tels que par exemple, la toxicité des fluides employés (porosimétrie à mercure). La base théoriques d'une nouvelle méthode pour obtenir la DTP a été proposée dans la littérature. Celle-ci est fondée sur l'injection de fluides à seuil, caractérisés par une contrainte de cisaillement en deçà de laquelle ils ne s'écoulent pas. L'idée principale de ces travaux théoriques est que l'écoulement de fluides à seuil à travers un milieu poreux permet d'obtenir sa DTP à partir de la mesure des débits correspondant à différents gradients de pression Q(∇P). L'objectif du travail proposé ici est de présenter une nouvelle méthode d'exploitation des données expérimentales Q(∇P) permettant d'obtenir de façon simple, robuste et reproductible les DTPs des milieux poreux analysés. La démarche consiste à évaluer la contribution au débit total des nouveaux pores qui s'incorporent à l'écoulement entre deux valeurs de ∇P. Ces nouveaux pores sont caractérisés par un rayon représentatif qui est fonction de la contrainte seuil du fluide et de ∇P. L'importance de leur contribution au débit total par rapport à celle d'un seul pore donne le nombre de pores dans l'échantillon ayant ce rayon représentatif. Cette méthode est d'abord testée et validée avec des expériences générées numériquement. Ensuite, elle est utilisée pour exploiter des données provenant d'expériences de laboratoire réalisées avec de différents milieux poreux. Les résultats obtenus en termes de DTPs sont comparés avec ceux fournis par d'autres techniques: porosimétrie à mercure et microtomographie<br>Current experimental methods used to determine pore size distributions (PSD)of porous media present several drawbacks such as toxicity of the employed fluids (e.g., mercury porosimetry). The theoretical basis of a new method to obtain the PSD by injecting yield stress fluids through porous media and measuring the flow rate Q at several pressure gradients ∇P was proposed in the literature. On the basis of these theoretical considerations,an intuitive approach to obtain PSD from Q(∇P) is presented in this work. It relies on considering the extra increment of Q when ∇P is increased, as a consequence of the pores of smaller radius newly incorporated to the flow. This procedure is first tested and validated on numerically generated experiments. Then, it is applied to exploit data coming from laboratory experiments and the obtained PSDs are compared to those deduced by mercury porosimetry and micro tomography

Dans ces dernières années nous assistons à l’émergence de nouvelles licences, les Creative Commons (CC), qui dérivent du monde du logiciel libre et qui ont pour but de partager les œuvres artistiques (vidéos, musique, etc.) entre les utilisateurs.

Thesis (MScEng)--Stellenbosch University, 2011.<br>ENGLISH ABSTRACT: The recent emergence of ubiquitous wireless connectivity and the increasing
computational capacity of modern vehicles have triggered immense interest in the
possibilities of vehicular connectivity. A plethora of potential applications for vehicular
networks have been proposed in the areas of safety, traffic infrastructure management,
information, and entertainment. The broad range of applications requires creative utilisation
of the available wireless medium, using a combination of existing and novel wireless
technologies. In this research the evaluation of one such configuration is performed.
Dedicated short range communication for safety applications is assumed, and the use of Wi-
Fi and WiMAX for non-safety applications is evaluated. Little is known about the media
streaming performance of these wireless technologies in realistic vehicular ad-hoc network
(VANET) scenarios. Due to the extreme mobility and unpredictable environmental aspects in
a real road environment, an empirical evaluation is performed and presented. Evaluation of a
multi-vehicle to infrastructure (V2V2I) VANET, using Wi-Fi for the vehicle-to-vehicle
communication and WiMAX for the vehicle to infrastructure (V2I) communication is
experimented. It is observed that Wi-Fi is unaffected by the vehicle speed; whenever nodes
are within communication range, data gets transferred normally. A detailed characterisation
of the network architecture is presented and the results show that a multitude of applications
can be supported with this proposed network architecture.<br>AFRIKAANSE OPSOMMING: Die toenemende beskikbaarheid en digtheid van koordlose netwerke en die verhoogde

benutting van die beskikbare en nuwe koordlose tegnologieë. Hierdie tesis evalueer een
voorbeeld van so ‘n opstelling. ʼn Toegewyde kortafstand kommunikasie modus vir
veiligheidstoepassings word aangeneem, terwyl Wi-Fi en WiMAX vir ander toepassings
evalueer word. Daar is min navorsing oor die kapasiteit en seinsterkte van hierdie beskikbare
netwerke onder realistiese voertuig netwerk (VANET) scenario‘s. Weens die hoë mobiliteit
van voertuie en ook die onvoorspelbaarheid van hierdie omgewing word ʼn empiriese
evaluasie beskou as die mees gepaste metode. Die navorsing ondersoek ʼn multi-voertuig-totinfrastruktuur-
netwerk wat Wi-Fi gebruik vir voertuig-tot-voertuig (V2V) kommunikasie en
WiMAX vir voertuig-tot-infrastruktuur (V2I) kommunikasie. Die navorsing bevind dat Wi-Fi
nie beïnvloed word deur die spoed van die voertuig nie: wanneer die nodes binne die bereik is
van die netwerk word data normaal oorgedra. ‗n Gedetailleerde karakterisering van dié
netwerk word gedoen en die resultate dui aan dat ‗n groot hoeveelheid toepassings
ondersteun kan word deur dié opstelling.

Thesis: S.M., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2017.<br>Thesis: S.M., Massachusetts Institute of Technology, Computation for Design and Optimization Program, 2017.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 57-60).<br>Fluid flow and particle transport through porous media are determined by the geometry of the host medium itself. Despite the fundamental importance of the velocity distribution in controlling early-time and late-time transport properties (e.g., early breakthrough and superdiffusive spreading), direct relations linking velocity distribution with the statistics of pore structure in 3D porous media have not been established yet. High velocities are controlled by the formation of channels, while low velocities are dominated by stagnation zones. Recent studies have proposed phenomenological models for the distribution of high velocities including stretched exponential and power-exponential distributions but without an underlying mechanistic or statistical physics theory. Here, we investigate the relationship between the structure of the host medium and the resulting fluid flow in random dense spherical packs. We simulate flow at low Reynolds numbers by solving the Stokes equations with the finite volume method and imposing a no-slip boundary condition at the boundary of each sphere. High fidelity numerical simulations of Stokes flow are facilitated with the assist of open source Computational Fluid Dynamics (CFD) tools such as OpenFOAM. We show that the distribution of low velocities in 3D porous media is described by a Gamma distribution, which is robust to variations in the geometry of the porous media. We develop a simple model that predicts the parameters of the gamma distribution in terms of the porosity of the host medium. Despite its simplicity, the analytical predictions from the model agree well with high-resolution simulations in terms of velocity distribution.<br>by Mohammad S Kh F Sh AlAdwani.<br>S.M.

Full textAbstract:
Marknadsföringens grund är spridning av information. Upplysning sker genom distribution till riktad intressegrupp som konsumerar marknadsföringens budskap. Marknadsföringen slår igenom om åskådaren köper budskapets känsla. Upplevelse av känslan utgår ifrån innehållets kontext som tilltalar individen emotionellt. Detta kandidatarbete syftar till att undersöka hur emotion och autobiografisk minne kan utnyttjas vid marknadsföring. Därmed utforska hur kontext i film engagerar ungdomar för rekrytering inom en teknisk nischad bransch. Kontext formas utifrån hur individen upplever den estetiska bilden. Därtill skapas ett sammanhang som individen relaterar till och sprider vidare i sitt sociala nätverk. I detta fall har denna undersökning experimenterat med representation av ventilationsbranschen för rekrytering. Omvärldsanalys användes för informationssökande om ventilationsbranschen. Designmetoder har använts för kommunikation av vision vid godkännande under iterativ designprocess. Till sist har bildmanipulation använts under filmproduktion som resulterade en rekryteringsfilm som involverar dess målgrupp. Rekryteringfilmen gestaltar ungdomar som ska rekryteras inom ventilationsbranschen och två utomstående som visar vilja till rekrytering. Estetisk symbolik förmedlar kontext som gestaltar känslan av anställning istället för beskrivning av upplevelsen. Skådespelarnas naturliga utförande reflekteras hos mottagaren som upplever känslan. Däremot har utmaningar under produktion fått oss att omstrukturera iterationer av detta projekt. Dilemman som COVID-19 pandemin och vår kommunikation till ventilationsbranschen utvecklade vår designförmåga. Med Löwgrens och Stoltermans exempel på hur designen hanterar dilemman med retrospektiv reflektion (Löwgren & Stolterman, 2004), har vår egen kreativitet använts vid reflektion över vad som vi kunde åstadkomma trots dilemmat. Rekryteringsfilmen kommer att distribueras efter COVID-19 pandemin har avtagit och marknadsföringen sätts på prov. Filmmediets emotionella koppling till människor kan därmed testas för vidare forskning.<br>The basis of marketing is dissemination of information. Enlightenment is provided through distribution towards targeted interest groups who consume the marketing message. The marketing works when the viewer buys into the emotion of the message. Experience of that emotion is based on the content´s context that appeals to the individual emotionally. This bachelor thesis aims at examination of how emotion and autobiographical memory can be used in marketing. Therefore investigate how context in film engages young people for recruitment in a technical niche industry. Context is formed based on how the individual perceives the aesthetic image. In addition, a context is created that the individual can relate to and spread it further in her social network. In this case, this study has experimented with the representation of the ventilation industry for recruitment. External analysis has been used for seeking information about the ventilation industry. Design methods have been used for communication of a vision upon approval during the iterative design process. Finally, image manipulation during film production was used to result in a recruitment film involving its target audience. The recruitment film depicts young people being recruited into the ventilation industry and two outsiders who show a desire for recruitment. Aesthetic symbolism conveys a context that embodies the feeling of employment rather than description of the experience. The actors' natural performance is reflected by the recipient who is experiencing the emotion. However, challenges during production have led us to revamp iterations of this project. Dilemmas such as the COVID-19 pandemic and our communication with the ventilation industry developed our design ability. With Löwgren’s and Stolterman’s example of how the designer handles dilemmas with retrospective reflection (Löwgren & Stolterman, 2004), our own creativity has been used in reflection upon what we could achieve despite the dilemma. The recruitment film will be distributed after the COVID-19 pandemic have diminished and the marketing will be put to the test. The film medium’s emotional connection to people can therefore be tested for further investigation.
