Bai, Guo. "Three Essays on Governance Designs in Digital Age". Thesis, Université Paris-Saclay (ComUE), 2016. http://www.theses.fr/2016SACLH011/document.
Pełny tekst źródłaThe main objective of this dissertation is to explain why coordinative efficiency, creative efficiency, together with static efficiency are all critical goals of governance design in digital age, and to explore innovative governance arrangements, beyond the one-dimensional line defined by “market” and “hierarchy”, that can facilitate the processes of integrative coordination, and collective creation in organizations.The dissertation is composed of three essays. Essay 1 is a theory paper that provides the overall theoretical arguments about why transaction cost economics (Williamson 1979, 1991, 1996, 2002) is no longer a satisfactory theoretical framework for governance design in the digital age, and offers a normative model which suggest possibilities of much more nuanced, complicated and pluralistic governance choices than suggested by transaction cost economics. It is argued that potential governance choices are not solely situated on a one-dimensional line between hierarchy and market, as transaction cost economics asserts. The rich connotations of socially constructed agency (Giddens, 1985; Greenwood et al. 2011) provide diverse possibilities of governance arrangements, which spread across a triangular plane in a three-dimensional space defined by static efficiency, coordinative efficiency and creative efficiency (see Figure 1). This paper provides both graphic and mathematical presentations of this three-dimensional model for governance design, which can be applied to different levels of organizing.Essay 2 and 3 are two empirical papers that endeavor to extend Essay 1 by finding out the exact relationship between certain innovative governance arrangements with organizations’ performance in coordinative and creative efficiencies. Essay 2 focuses on the realization of integrative coordination in organizations. It found out that layered distributed organizational structure (Simon, 1962), broad-brushed ex ante plan (Edmondson, Bohmer and Pisano, 2001), and semi-structures (Brown and Eisenhardt, 1997) are beneficial in facilitating an ongoing coordination process when interdependencies are complex and uncertain. Essay 3 focuses on organizations’ performance in collective creativity (Shalley et al., 2004; George, 2007), especially on what governance arrangements can best allow collective creativity to emerge without overly sacrificing organizational stability and efficiency. It is discovered that “ordered disruption”, including ordered spatial disruption, ordered temporal disruption and ordered affective disruption, have positive effects on the emergence of collective creativity. Both Essay 2 and Essay 3 use collaborative organizations on smart city projects as the empirical setting. The findings of these two empirical papers are grounded on multiple case studies on those collaborative organizations

Pełny tekst źródłaVästvärldens energianvändning har nått oanade höjder, och ökar varje dag. Därför har energieffektivitet blivit ett hett ämne, både på liten och stor skala. Varje enskild individ har möjlighet att förbättra sin energieffektivitet och därmed sin energianvändning med märkbara skillnader, och bör agera därefter för miljöns skull. Rapporten börjar med en studie av olika regleringar och bestämmelser om energieffektivitet. Efter det kommer en litteraturstudie om vilken teknik som finns tillgänglig inom alla delar av hemmets energianvändning. Slutligen utförs en fältstudie på en lägenhet i Stockholm för att avgöra hur mycket energi som kan sparas, och vilka ekonomiska följder detta har. Resultatet visar att det i allmänhet inte är ekonomiskt hållbart att byta till den senaste energieffektiva tekniken inom hemmets apparater, utan att man får avse de miljömässiga vinsterna som incitament för dessa uppgraderingar. Ungefär 10% av den totala årliga energianvändningen kunde sparas genom att åtgärda alla apparater och funktioner i huset, utan avseende på uppvärmning och isolering.

Impeding Efficiency is based on my interest in the manner in which we experience space and in particular, the moment we become conscious of our surrounding built environment. The point of change between spaces, the threshold. Contemporary society lives in fast-forward; everything we do has been streamlined, developed in principles of efficiency. This phenomenon has caused a divide between user and the experience of architecture. We move rapidly, only with goal in mind, very rarely pausing, to adjust and reflect on our surroundings. This sparked a study of the threshold in architecture through the lens of four architects and the architectural strategies they have applied in a manner that impedes efficiency, hinders mobility, slows down time and allows for personal interpretation of the build environment.

Pełny tekst źródłaOne of the used strategies to increase the spectral efficiency (SE) of cellular network is to reuse the frequency bandwidth over relatively small areas. The major issue in this case is higher interference, decreasing the energy efficiency (EE). In addition to the higher bandwidth, densification of the networks (e.g. small cells or multi-user multiple input single output, MU-MISO) potentially increases the area spectral efficiency (ASE). The total energy consumption of the wireless networks increases due to the large amount of circuit power consumed by the dense network structures, leading to the decrease of EE. In this thesis, the EE-SE achievable region is characterized in a hexagonal cellular network considering several frequency reuse factors (FRF), as well as shadowing. The EE-ASE region is also studied using Poisson point processes (PPP) to model the MU-MISO network with signal-to-leakage-and-noise ratio (SLNR) precoder. Different base station (BS) densities and different number of BS antennas with static power consumption are considered.The EE-SE region in a hexagonal cellular network for different FRF, both with and without shadowing is first characterized. When shadowing is considered in addition to the path loss, the ε-SE-EE tradeoff is proposed as an outage measure for performance evaluation. The EE-SE curves have a large linear part, due to the static power consumption, followed by a sharp decreasing EE, since the network is homogeneous and interference-limited. The results show that FRF of 1 for regions close to BS and higher FRF for regions closer to the cell edge improve the EE-SE optimal point. Moreover, better EE-SE tradeoff can be achieved with higher outage values. Besides, FRF of 1 is the best choice for very high outage value due to the significant signal-to-interference-plus-noise ratio (SINR) decrease.In downlink, precoders are used in space division multiple access (SDMA) MU-MISO cellular networks to improve the SINR. Stochastic geometry has been intensively used to analyse such a complex system. A closed-form expression for ASE in asymptotic regime, i.e. number of antennas and number of users grow to infinity, has been derived using random matrix theory and stochastic geometry. BSs and users are modeled by two independent PPP and SLNR precoder is used at BS. EE is then derived from a linear power consumption model. Monte Carlo simulations show that the analytical expressions are tight even for moderate number of antennas and users. Moreover, the EE-ASE curves have a large linear part before a sharply decreasing EE, as observed for hexagonal network. The results also show that SLNR outperforms the zero-foring (ZF) precoder, which is typically used in literature. Numerical results for SLNR show that deploying more BS or a large number of BS antennas increase ASE, but the gain depends on the BS-user density ratio and on the number of antennas when user density is fixed. EE increases only when the increase in ASE dominates the increase of the power consumption per unit area. On the other hand, when the user density increases, ASE in interference-limited region can be improved by deploying more BS without sacrificing EE and the ergodic rate of the users

Pełny tekst źródłaCreating sustainable shareholder value is at this time accepted as one of the mostimportant strategic objectives for financial institutions. Generating stable shareholder value growth requires an intense focus on delivering benefits to customers in the most efficient way, hiring and retaining motivated personnel, maintaining excellent relationship with other firm stakeholders.This thesis provides an analytical assessment of shareholder value creation in banking. The first part of the text provides a framework for analysing shareholder value theory by discussing how shareholder value can be defined, if it can be considered a valid strategic objective for banks, how shareholder value can be measured and how it can be created.The second part of the text presents empirical investigations in order to measureshareholder value and some of it drivers. The final part analyses the importance of these drivers in creating shareholder value. In order to have a broad view of the sector, the sample analysed comprises commercial Tunisian banks listed on Tunisian stock exchange between 1995 and 2009. We use a panel model to examine the determinants of bank's shareholder value reaction (measured by EVA and its components) as a linear function of various bank-specific, industry-specific and macroeconomic. We find that various factors are found to be statistically significantdeterminants of economic profits and shareholder value created by banks. Consistently with the previous literature, we find that cost and revenue efficiency are positively related to bank performance: namely, economic profits are found to have a positive link with revenue efficiency improvements, while EVA is positively related to cost efficiency improvements. Secondly, we find a positive relationship between credit losses and shareholder value providing evidence that higher unexpected losses imply larger business volume and perhaps lower loan portfolio quality. Thirdly, we observe a positive link between bank's leverage and economic profits, but not with EVA. This is due to the positive relationship between financial leverage and the cost of capital, overall, greater financial leverage increase economic profits but this is compensate by higher costs of capital

Pełny tekst źródłaCan statistical analysis of professional basketball players lead to a more efficient evaluation of a player's worth? Following the recent success of statistic-driven baseball franchises, many basketball executives and followers are beginning to mine the sport's production in search of an all-encompassing player value rating. Teams could thus exploit undervalued players, leading to increased team and fan welfare. My thesis addresses this ongoing debate by examining various player and team statistics in the National Basketball Association (NBA). While I find significant relationships between individual efficiency statistics and team success, I also discover the paramount importance of defensive statistics and balanced team payrolls. This paper proposes a model that would help team executives find players who promote team efficiency, rather than individual production

Energy efficiency is an important consideration in energy policy-making. So, a federal program aimed at funding "energy efficiency retrofits" for low-income households could be an important step in increasing the overall efficiency of energy use in America. If each eligible household reduces the amount of energy it currently wastes by weatherizing, the US could save 127 billion pounds of carbon dioxide. The Department of Energy's Weatherization Assistance Program, that performs energy efficiency retrofits for low-income households, has been funded by over a 20- fold increase due to Stimulus Funding (formally, the American Recovery and Reinvestment Act of 2009). This increase has caused a serious need for a labor ramp-up to meet the program implementation goals of 1 million to 2 million low-income homes weatherized per year, as compared with the previous level of 100,000 homes a year. This program will only work, however, if the necessary workers can be trained and deployed quickly. This need for labor ramp-up creates a puzzle though. The interests of expanding the weatherization effort quickly and effectively are often posed against the interest of creating quality jobs for marginalized workers. The stakeholders representing each interest-low-income energy efficiency advocates and Green Collar Job Advocates-are both working for the interests of the low-income people, creating some hope for a positive, mutually agreeable solution.
(cont.) This thesis attempts to bridge this gap by documenting how the need for thousands of weatherization workers might be handled in a way that not only stimulates the national economy-the primary goal of the current national economic stimulus effort--but also provides Auditor and Installer jobs for marginalized workers in a way that leads to fruitful long-term employment. Based on my review of ramp-up and weatherization efforts in Massachusetts, I find that collaborative efforts involving existing Community Action Programs, labor unions, Utility companies, neighborhood organizations and educational institutions that prioritize training for long-term skill development may well be possible to promote energy efficiency in a way that addresses both our long-term need to reduce the burning of fossil fuel and our urgent need to stimulate the US economy and improve the economic lot of the most marginalized in US society.

Pełny tekst źródłaIndustriellt byggande har de senaste tio åren ökat sina marknadsandelar från 2% till 15% på den svenska bostadsmarknaden för flerfamiljshus. Prefabricering har utvecklats till industrialisering, där fabriker inte bara producerar komponenter för montering på byggplats, utan tar även helhetsansvar för försäljning, konstruktion, i fabrik och för montering av bostäder. Utvecklingen av en mer automatiserad produktion ställer högre krav på projekteringen. Som en definierad flaskhals måste tid frigöras från koordinering till kärnverksamhet för att skapa förbättringar och tillåta produktutveckling. Med förändringen från ritningsbaserad till modellbaserad byggprojektering, ges möjligheten att arbeta samtidigt för bättre effektivitet. Fokuseringen på BIM-stöd med CAD-verktyg har lett till att utvecklare skapar system som i huvudsak stödjer produktmodellering. För industriellt bostadsbyggande, är stöd för effektivitet i projekteringsprocessen lika viktig. Empiri har samlats genom intervjuer, observationer och dokumenterade aktiviteter i en fallstudie hos en svensk industriell bostadsbyggare för att analysera vilka komponenter och funktioner som ett stödsystem för projektering behöver för att skapa värde för företagen. Resultaten visar att en definition av projektering i steg med gater, aktiviteter för samplanering och användandet av metoder för att visualisera processen har ökat effektiviteten med omkring 41 % för informationsleveranser. Dessutom visar studien att stödsystem bör kunna skapa både internt värde för effektiva informationsleveranser och yttre värde för att möta och hantera kunders krav på ett standardiserat sätt. Ett stödsystem, baserat på produktutvecklingsteorier med axiomatisk design som grund, kan kombinera både produktstruktur med BIM- funktioner och processrelaterade funktioner för planering och därmed säkra kvaliteten mellan discipliner för samverkande arbete. Product life cycle management (PLM) är ett övergripande koncept för hantering av produktutveckling i ett livscykelperspektiv, vilket har ett definierat regelverk som är applicerbart på industriell byggprojektering, både för utvecklare av IT-system och för industriella husbyggare.

We proposed, designed, and demonstrated a first-of-a-kind millimeter-scale thermophotovoltaic (TPV) system using a metallic microburner, photonic crystal (PhC) emitter, and low bandgap TPV cells. Many technologies (fuel cells, Stirling, thermoelectric, etc.) that potentially enable a portable millimeter-scale hydrocarbon microgenerator are under active investigation because conventional fuels offer energy densities fifty times that of batteries. In a TPV system, combustion heats an emitter to incandescence and the resulting thermal radiation is converted to electricity by photovoltaic cells. Our approach uses a moderate temperature (1000{1200°C) microburner coupled to a high emissivity, high selectivity PhC selective emitter and low bandgap TPV cells. The PhC emitter and low bandgap cells minimize total microgenerator mass by enabling simultaneous high eciency and high power density, even at moderate temperatures which allow ecient coupling to the combustion process by reducing undesired heat loss mechanisms. This approach is predicted to be capable of up to 30% ecient fuel-to-electricity conversion within a millimeter-scale form factor. Although considerable technological barriers need to be overcome to reach full performance, we have performed a robust experimental demonstration that validates the theoretical framework and the key system components. We first demonstrated a first-of-a-kind TPV system built from a 1010 mm catalytic silicon MEMS microburner with a Si/SiO₂ 1D PhC matched to the InGaAsSb (Eg = 0:55 eV) cells which achieved 2.7% fuel-to-electricity eciency, a millimeter-scale record, at a power of 344 mWe. We then proposed, designed, and demonstrated a highly robust metallic platform comprised of a 2020 mm Inconel microburner and a higher performance 2D tantalum PhC emitter. With the new system, we experimentally demonstrated a similar eciency but can achieve 5% with simple mechanical improvements. These two experimental demonstrations will pave the way for a lightweight, high energy density TPV microgenerator. We modeled a complete microgenerator based on the experimental system and found an energy density of 850 Wh/kg and power density of 40 W/kg are achievable.

Pełny tekst źródłaDairy farming, the most important farming sector in the European Union, has been subject to considerable de-regulation since the 2005 EU Common Agricultural Policy came into effect and to increased commodity price volatility. This is a new challenge for dairy farms, since price volatility is related to farm-level decision-making with regard to the optimal factor allocation in the long run. A vast body of literature relates economic efficiency to dairy farm characteristics such as size or managerial ability. However, it is common for static approaches of efficiency which ignore the role of time and the adjustment processes of farms with respect to the quasi-fixed factors to be applied. The intertemporal linkages of production and investment decisions are emphasized by dynamic efficiency and an extended model incorporates factor price volatility. The contribution of this thesis is to analyze the dynamic efficiency of German dairy farms under uncertainty, which thus far has not been done. The application aims to investigate whether West German dairy farms use their production factors in a technically and allocative efficient way in the long run. Moreover, the application will explore the role of uncertainty for factor demand and efficiency measurement. The results show that the farms operate at high levels of technical efficiency in comparison to allocative efficiency and that feed demand is negatively related to the variance of the feed concentrate price. Investment is negatively related to the variance of the milk price and the effect increases with farm size. The results further show empirical evidence for considering uncertainty when deriving (dynamic) efficiency measures: neglecting uncertainty within the estimation procedure will underestimate the average efficiency score, and thus farms appear inefficient. This finding is not only interesting for dairy farms; it also applies to other sectors that operate in highly-volatile markets.

Pełny tekst źródłaKonceptet digitalisering har blivit allt mer utbrett på grund av den enorma datorkraft som finns i våra nuvarande digitala maskiner. Den svenska sjukvården har fokuserat på digitalisering i form av e-hälsa under det senaste decenniet och antalet digitala tjänster ökar snabbt. Genom att använda modern teknik för att skapa smartare och effektivare processer är det möjligt att förbättra kvaliteten för patienter och användare.Det finns ett behov av mer tillförlitlig kunskap om digitalisering och dess potential för effektivitet. Detta projekt har som mål att undersöka denna effektivitet. Syftet är att direkt bidra med mer data om ämnet digitalisering.Detta projekt bygger på en kvalitativ forskningsmetod samt en fallstudie för att genomföra effektivitetsprov och jämföra manuella med digitaliserade arbetsprocesser.Den använda forskningsmetodiken består av en litteraturstudie, konstruktion av en digitaliserad process, samt två tester där vardera test utvärderar både en manuell och digital process. Processerna innefattar dokumentgenerering och kommunikation, inom sjukvården.Testresultaten visar att digitalisering uppnår en total effektivitetsökning på 333% när alla resultat sammanställs. Överlag är det från resultaten uppenbart att digitalisering leder till ökad effektivitet. Effektiviteten som uppnås varierar från process till process. I det generella fallet observeras ökad effektivitet, men ibland även minskad.

Pełny tekst źródłaKlimatförändringarna driver utvecklingen mot att energianvändningen i den byggda miljön behöver minska. Byggnader står för nästan 40% av den totala energianvändningen och cirka 35% av utsläppen av växthusgaser i Europa. EUs medlemsländer är bundna att förbättra energieffektiviteten hos befintliga byggnader, till exempel genom att skärpa byggreglerna och utveckla handlingsplaner. Eftersom energieffektiviseringar kan påverka värden i kulturhurhistoriska byggnader, är dessa ofta undantagna från krav som syftar till att minska energianvändningen i byggnader. Energibesparing och resurshushållning har gradvis blivit omfamnad av kulturmiljösektorn och kulturhistoriska byggnader betraktas allt mer som en del av lösningen på klimatförändringarna. I licentiatavhandlingen diskuteras metoderna för att identifiera kulturhistoriska värden i en byggnad och hur den underliggande teorin påverkar olika scenarier i en energieffektiviseringprocess. Valet av bevarandeteori och bevarandestrategi påverkar framgångsfaktorn i energieffektivseringen och hur mycket energianvändningen i en kulturhistorisk byggnad kan minskas. I denna avhandling föreslås därför ett teoretiskt ramverk för att förstå effekterna av de olika kulturhistoriska bedömningar som kan göras, antingen genom att använda ett objektivistiskt eller en relativ syn på hur en en byggnads kulturhistoriska värden skapas och bäst bevaras. Utifrån detta teoretiska ramverk har ett stöd för beslutsfattande utvecklats för att ytterligare beskriva effekterna av de olika bevarandestrategiernas påverkan på implementeringen av olika energieffektiviserande åtgärder. Andra resultat visar att en majoritet av de granskade forskningspublikationerna fokuserade på den operativa energin i en byggnad och bara ett fåtal gällde energianvändning under hela livscykeln i en byggnad. Dessa analyser används för att utvärdera var de flesta energibesparingar kan göras och ofta identifiera svaga punkter i byggnadens klimatskal eller tekniska system. Om det nämndes alls tenderade inflytandet av kulturella och historiska faktorer på energieffektivitetsåtgärder som tillämpas på arvsbyggnader endast att bedömas kortfattat. Faktum är att majoriteten av de genomgångna publikationerna inte beskriver bevarandeprinciper och inte nämner den metod som används för att bedöma eller definiera kulturhistoriska värden. Istället används ofta en explicit (ibland en implicit) förståelse för bevarande som i huvudsak något som inte förstör ursprungligt material och därmed autenticitet i en byggnad. Denna licentiatavhandling består av en separat undersökning, en litteraturöversikt och en utökad kappa. Studien är inriktad på ett svenskt och europeiskt sammanhang, särskilt när det gäller klimatförhållanden och diskussioner om byggregler och teori och praktik för kulturhistoriskt bevarande av byggnader. Den är en del av det växande forskningsområdet energieffektivisering i kulturhistoriska byggnader och avhandlingen syftar till att bidra till en ökad förståelse för hur utvärderingen av kulturhistoriska värden i byggnader påverkar arbetet med att göra dem mer energieffektiva. Huvudforskningsfrågan är: Hur påverkar olika metoder för bedömning och utvärdering av kulturhistoriska värden energibesparande åtgärder i kulturhistoriska byggnader?

Pełny tekst źródłaEl primer capítulo estudia los efectos de cambios en el concepto de equilibrio utilizado. Por un lado se introduce el concepto del "strong Tiebout equilibrium" (Greenberg and Weber, J. of Econ. Th. 38, 1986, 101-117). Se muestra que el equilibrio de Alesina y Spolaore es robusto a este cambio ya que se puede entender como un "Strong Tiebout equilibrium" específico que se elige según las reglas de la formación de países utilizadas por Alesina y Spolaore. Esto implica propiedades adicionales para el equilibrio de Alesina y Spolaore que son deseables. Por otro lado se modifican las reglas de la formación de países para acercarlas a las reglas utilizadas en la realidad. Esto lleva al problema de la noexistencia del equilibrio.
En el segundo capítulo, se analiza el cambio de un modelo con una población que es un continuo a un modelo con un número finito de agentes. Un número finito es un supuesto tradicional de la literatura de la formación de coaliciones. Es deseable que las conclusiones que se derivan utilizando la herramienta poderosa de un continuo de agente se confirmen para un número elevado pero finito de agentes. El análisis utiliza conceptos de estabilidad básicos que son débiles. Por lo tanto se encuentra una multiplicidad de equilibrios. Algunos son eficientes en el sentido de Alesina y Spolaore mientras que otros no lo son.
Finalmente, el tercer capítulo extiende el análisis del segundo empleando nociones de estabilidad más fuertes. Como la aplicación de los conceptos de estabilidad de Alesina y Spolaore crea problemas en el modelo con un número finito de agentes, se utiliza la noción del "strong Tiebout equilibrium". Se encuentra una multiplicidad de equilibrios que aun siendo menor que en el segundo capítulo no permite confirmar la conclusión de Alesina y Spolaore.
The thesis consists of three Chapters that analyse the formation of countries. Starting point is a paper by Alesina y Spolaore (The Quart. J. of Econ. 112, 1997, 1027-1056) that proposes an analytical framework for the normative and positive analysis of this question. The fundamental result of this work is that in equilibrium one generally observes an inefficiently large number of countries. This thesis carries out a test of robustness of this result to changes in the assumptions of the model. These changes are motivated by the literature on coalition formation.
The first Chapter studies the effect of a change in the equilibrium concept. On one hand the concept of a strong Tiebout equilibrium (Greenberg and Weber, J. of Econ. Th. 38, 1986, 101-117) is introduced. It is shown that the equilibrium of Alesina y Spolaore is robust to this modification because it can be understood as the unique outcome of a selection among all strong Tiebout equilibria where the selection is driven by the specific rules of country formation. This implies additional desirable properties of the equilibrium of Alesina y Spolaore. On the other hand the rule of country formation are modified in order to make them closer to the rules used in reality. This leads to the problem of non-existence of an equilibrium.
The second Chapter analyses the change from a continuum of agents to a finite population. A finite number of agents is traditionally assumed in the literature on coalition formation. Moreover it is desirable that the conclusions derived using the logical construct of a continuum of agents are confirmed for a large but finite number of agents. Since the analysis employs weak stability concepts, a multiplicity of equilibria arises for some of which the inefficiency result is true while for others it is not.
Finally the third Chapter extends the investigation of the second using stronger stability notions. Since the stability concepts of Alesina and Spolaore lead to problems in the model with a finite number of agents, the notion of a strong Tiebout equilibrium is employed. Although this reduces the number of equilibria found in the second chapter, it does not allow to confirm the inefficiency result of Alesina and Spolaore.

Pełny tekst źródłaThe thesis is structured in three chapters, which are briefly described in this section: Chapter II presents a literature review on actual financing schemes in several countries, and is compared to the current health system in México mainly integrated by global budget, capitation and direct payments. A metafrontier approach is used to identify efficiency among hospitals under different technologies according to their financing scheme, relative to the potential technology available to all healthcare system. As part of the efficiency results previously obtained for private hospitals, Chapter III evaluates technical efficiency and potential presence of scale and scope economies to improve management decisions, based in the production function, scale and scope economies theories. Non-parametric methodology is used to calculate efficiency scores for scale economies valuation. Then a two-staged model for diversified and specialized hospitals was used to calculate the scope economies valuation. This chapter has been accepted and published in the journal Salud Pública en México (year 2014, volume 56, number 4, pages 348-354). Chapter IV evaluates a strategic hospital alliance by using a metafrontier concept to compare the efficiency between Mexican hospital alliance members and a control group. Hospital capacity utilization ratios are used as the maximum rate of output possible from fixed inputs in a frontier setting, using directional distance functions. Finally, Chapter V presents the conclusions and main contributions of the thesis, and suggestions for future research. Table 1.1 indicates a summary of the main elements described earlier in each chapter.

Pełny tekst źródłaThis degree project has been made in cooperation with engineers working for GM Engineering/Saab Automobile AB in Trollhättan. The given name by Saab for the project is “Fuel efficiency improvements in All Wheel Drive(AWD)-system”. The main tasks of this thesis work were to investigate the size of the power losses in different parts on the propeller shaft, to design a computer program that calculates
coordinates and angles on a propeller shaft and to investigate the possibilities to put together a simplified formula that calculates the natural frequencies on a propeller shaft.
The main parts of this report are a compilation of the theory about AWD and mostly about the parts on the propeller shaft, and also a description of the developed computer program called Propeller Shaft Calculator. This report doesn’t concern power losses in the different joints because there were no such general equations to be found. The most common way to calculate the power losses inside a joint is to do tests were the power loss is measured at different angles, torque and speed and then use that data to put together an approximated equation.
Most of the work on this project has been on theory studies and on programming. The main result of the project is the program Propeller Shaft Calculator.
Propeller Shaft Calculator is a program that is designed in Microsoft Excel. All the menus are programmed in the visual basic editor in Excel. The program is supposed to be used as a help while designing new propeller shafts.
Propeller Shaft Calculator can calculate all the coordinates, lengths, angles and directions on a propeller shaft. It also calculates natural frequencies, plunge, estimated power loss on the second shaft and angles in the joints. In the program you can choose to do calculations on four different configurations of propeller shafts but can quite
easy upgrade the program with more choices.
Basically the program works like this:
First you choose the right propeller shaft in the main menu. Then you fill out the indata sheet with coordinates, lengths, material data and so on. As you type in the input data the output data will appear in the out-data sheet next to the in-data. Every propeller shaft has also a calculations sheet were more detailed calculations can be
found.
The program also has a built in help function and a warning function that lights a warning sign next to the values if they are outside the limits.

Thanks to the fast developing high technology nowadays, mobile telecommunication 4G/LTE is popularized worldwide, and which makes a rapidly growing New Media related Industry.With the higher requirement for good quality an-d high resolution of Video/Webcam , the bandwidth and the amount of coding compressed data for transmitting Video have to be expanded. In order to keep high performance of video under efficient data compression, more complicated mathematical calculations is a must.In the newest HEVC, CU is quite diversified in order to match different resolution requirement as well as to support higher resolution. Since the bandwidth of audio and video on mobile internet device is limited, our major target is to settle bandwidth problem on high resolution video, that is , to narrow the bandwidth. This thesis puts forward the algorithm of Bandwidth-Rate-Distortion Optimization (BRDO), which is on basis of Rate-Distortion Optimization. The algorithm distributes bandwidth and search area by size of Rate-Distortion Cost (RDCost). It not only lowering the usage of bandwidth but maintaining quality and rate. On average, more than 56% of bandwidth's usages were saved and more than 60% of encoding time decrease largely. The hardware architecture was implemented by using Synopsys (Verilog, Verdi, Design Compiler, Synthesis, PrimeTime®, PrimePower®) and Cell Library (TSMC 90nm CLN90G). The speed of our design was 1.1GHz under the worst case simulation case, and the power consumption was 0.873mW.
