Full textA investigação desenvolvida nesta dissertação centra-se no binómio Direitos de Propriedade / Política de Pescas. A transição de um regime de livre acesso para políticas de limitação à entrada e atribuição de quotas (mais ou menos transferíveis) significou uma alteração sensível na forma de entender os problemas das pescarias e de as ordenar de forma eficiente.A criação do regime das 200 milhas, ao atribuir aos países costeiros, direitos de propriedade e novas prerrogativas na gestão dos seus recursos, representou um imenso potencial para uma gestão sustentável das pescas, uma "Promessa de Abundância". A prática demonstrou que, sem uma política de redução da sobrecapacidade, e em presença de restrições de ordem social e política , estas conclusões devem ser relativizadas. Por outro lado, os problemas derivados da imprecisa definição de direitos nas zonas de Alto-Mar adjacentes às ZEEs, na Lei do Mar ( 1982), nomeadamente os relativos aos straddling stocks, implicam uma revisitação da "Tragédia dos Comums" e da relação entre regras de acesso e sobrepesca. Isto podemos comprovar pela análise do caso: A pesca do bacalhau na Terra Nova. Simultaniamente, avaliamos os efeitos da criação do regime das 200 milhas sobre a frota de pesca longínqua portuguesa que, tradicionalmente, pratica aquela pescaria.
In this dissertation we investigate Rights Based Management. The transition from free access to regulated fisheries with tools like limited entry and quotas (of different degrees of transferability) meant an important evolution in the way of understanding fisheries problems and managing them efficiently. Extended Fisheries Jurisdiction gave the coastal states property-rigths and the potential of a sustainable management of their fisheries resources. For many fisheries economists it was a "promise of abundance". In practice, without a policy of overcapacity reduction, and in the presence of multiple social and political constraints, these conclusions were reversed. Also, the problems of "unfinished business" in the Law of the Sea ( 1 982), namely the imprecise definition of rights in the areas of High-Seas adjacent to the EEZs and the consequent difficulties in the management of straddling stocks, makes it necessary to revisit the "Tragedy of the Commons" and the oldest issue: free access/ excess of effort/ overfishing. We could corraborate this by the analysis of cod fisheries in Newfoundland/Canada. We also avaliate the consequences of Extended Fisheries Jurisdiction and European Community integration on the Portuguese long-distance cod fisheries.

Full textENGLISH ABSTRACT: This study explores the feasibility of establishing a diversified hotel property fund (DHPF) on the Johannesburg Stock Exchange. To be launched in 2005/2006, the proposed unit trust fund is made up of a diversified portfolio of hotels located throughout South Africa. Research suggests that Hotel Property Funds have traditionally been the most volatile of Real Estate Investment Trusts (REITs) with their share value largely dependent on hotel revenue. However, investing in HPFs and REITs have numerous advantages such as their stipulated 90% dividend-payout ratio, steady stream of cash flow and zero corporate income taxes. The Property Unit Trust sector in South Africa in 2003 realised annualised rates of returns of 39%, and furthermore, the economic outlook and hotel industry sector show promising signs with economic growth rates for 2004 and 2005 reaching 4% and 5% respectively. This study thus considers whether a hotel property fund will succeed in South Africa and what returns investors can expect. By drawing on empirical and primary research and lessons learnt from international best practices this ground-breaking report identifies and analyses key performance variables of HPFs and REITs and applies them to a South African context. These variables include; capital structure, investment strategy, risk and return, Net Asset Value (NA V) and initial public offerings (IPO's). The report establishes that there is no optimal capital structure for REITs and only when the market reacts to the issuance of debt can one tell if the REIT is favourably structured or not. Concerning investment strategy, investors are in general, often lured to a diversified portfolio, however this report suggests that there is no optimal strategy for investing in REITs. In addition, over a medium to long term, REIT performance is strong, while over the short term performance is varied impacting on investor strategy. In assessing risk and return it was concluded that including REIT shares in an already diversified portfolio, the maximum expected return for each given level of risk is increased, and the level of risk for each level of expected return is reduced. Furthennore, the performance of RElTs is not necessarily detennined by size or Net Asset Value and thus small and large REITs can offer investors similar returns. Finally, initial-day returns for industry lnitial Public Offerings (lPO's) easily outperfonn REIT lPO's. Similarly to RElTs, there are numerous advantages to Hotel REITs which include, unlocking and redeployment of capital, investment spread and risk reduction and the provision of synergies between counter cyclical performing properties. However, empirical research indicates that Hotel REITs prove to be the most volatile of REIT sectors. Hotel REITs differ enonnously from their parent group in terms of their revenue & earnings which are more diverse in source and are generated from short-tenn leases. As such. Hotel REITs are also considered to be more management intensive. As with REITs there is no evidence to suggest an optimal capital structure and with the envisaged 50% debt ratio, the DHPF could be considered to be following international best practices. Several drawbacks with Hotel REITs include the lowest dividend yield among all RElT sectors, high volatility in income earnings, sensitivity to upswings and downturns in the tourism market, large capital investments and fixed operating expenses for staff and infrastructure. However despite these obstacles and in answer to the research problem, the prospects of the DHPF succeeding in South Africa are very high indeed. The REIT and Hotel REIT markets have proved successful throughout major capital markets, providing investors with a multitude of benefits. South Africa's economic and tourism climate is very favourable. The Property Unit Trust (PUT) sector has performed immensely well and investors can expect a healthy return which, as shown, is considerably higher than other investments. Finally, the fund is being spearheaded by a high calibre DHPF management team, which is key to the listing and management of the fund.
AFRIKAANSE OPSOMMING: Hierdie studie ondersoek die moontlikheid om 'n Diverse Hotel Eiendomsfonds (DHEF) op die Johannesburgse Aandelebeurs te loods. Die huidige aanvangsfase sal in 2005/2006 wees, en sal bestaan uit 'n portfolio van verskillende hotelle wat reg oor Suid-Afrika versprei is. Die navorsing toon dat hoteleiendomsfondse tradisioneel die mees veranderlikste van die Eiendoms Beleggings Trusts (EBT) was en dat die aandeel waarde hoogs afhanklik is van die hotel se inkomste. Nieteenstaande, het investering in DHEFs en EBTs 'n verskeidenheid van voordele soos die voorgeskrewe 90% dividend uitbetalingspersentasie, 'n bestendige kontantvloei en geen korporatiewe inkomstebelasting nie. Die eiendomsbeleggingsfondse sektor in Suid-Afrika het gedurende 2003 'n jaarlikse groei van 39% getoon, en verder beloof die ekonomiese uitkyk in die hotel bedryf om tussen 4% en 5% gedurende 2004 en 2005 onderskeidelik te groei. Gegewe die inligting, is die vraag dus of 'n hoteleiendomsfonds sukses kan behaal in Suid-Afrika en watter opbrengs beleggers kan verwag. Deur na primere empiriese navorsing, sowel as lesse wat geleer is deur beste internasionale praktyke, te bestudeer, identifiseer hierdie verslag sleutel prestasie veranderlikes van EBTs en DHEFs plaas dit in konteks van Suid-Afrika. Hierdie veranderlikes sluit in: kapitaaistruktuur, beleggingsstrategie, risiko en terugkeer, Bruto Bate Waarde (Net Assest Value) (BBW) sowel as aanvanklike openbare aanbod (Initial Public Offering) (AOA). Daar is bevind dat daar geen optimale kapitaalstruktuur vir DHEFs bereken kan word nie. Verder word aangetoon dat daar slegs bepaal kan word of EBTs se struktuur voordelig is wanneer die mark reageer op nuwe skuld wat aangegaan is. Wat beleggingsstrategie betref, is beleggers oor die algemeen meer aangetrokke tot 'n diverse portefeulje van beleggings. Hierdie verslag bevind egter dat daar geen optimale strategie is om in EBTs te bele nie. Daar word verder bevind dat medium- tot langtermyn opbrengste goed vertoon, terwyl prestasie oor die korttermyn wisselvallig is wat gevolglik 'n invloed op beleggers se strategie het. In waardering van risiko en wins, is dit bepaal dat die insluiting van EBT aandele in 'n diverse portfeulje, die maksimum verwagte opbrengs vir elke vlak van risiko verhoog en dat die vlak van fisiko vir elke vlak van die verwagte opbrengs verlaag word. Verder is daar bevind dat die prestasie van EBTs nie noodwendig bepaal word deur batewaarde of -groote nie en klein EBTs kan beleggers vergelykende opbrengste bied. Eerstedag opbrengs vir industriele AOAs presteer beter as die van EBTs. Soortgelyk aan EBTs is daar verskeie voordele aan hotel EBTs wat die ontsluiting en herontplooiing van kapitaal, beleggingsverspreiding en risikoverlaging insluit. Empiriese navorsing dui aan dat hotel EBT's die mees onstabiele van die EBT sektor is. Hotel EBT's verskil wesenlik van ander EBTs in terme van opbrengs en verdienste wat meer divers is in oorsprong en gegenereer word deur korttermyn huurkontrakte. Hotel EBTs word ook gesien as meer bestuursintensief. Net soos met EBTs is daar geen bewyse dat daar 'n optimale kapitaalstruktuur bestaan nie en met die verwagte 50% skuld verhouding, volg DHEF wereldwye beste praktyk. Daar is verskeie nadele aan hotel EBTs, insluitend die laagste dividenduitkeer onder alle EBT sektore, hoe vlakke van onstabiliteit in verdienste, sensitiwiteit vir opswaai en afloop in die toerismemark, groot kapitaalbelegging en hoe vaste operasionele uitgawes op werknemers en infrastruktuur. Die gevolgtrekking is dat ten spyte van negatiewe faktore, die vooruitsig dat DHEF in Suid-Afrika sal slaag, hoog is. Die EBT en hotel EBT mark het bewys dat dit suksesvol is in talle ander groot kapitaalmarkte wat beleggers met 'n verskeidenheid van voordele kan voorsien. Suid-Afrika se ekonomiese- en toerismevooruitsig is baie positief. Die Eiendoms Eenheids Fonds (EEF) sektor het goed vertoon en beleggers kan 'n gesonde opbrengs verwag wat, soos aangedui word, aansienlik hoer is as ander beleggings. Die fonds word gedryf deur 'n hoe kaliber bestuurspan wat krities is tot die notering en die bestuur van fondse.

Full textObjective: This thesis aims to gain a deeper understanding of IPO activity by real estate firms, and why its volume varies over time. The objective is also to obtain the impacts of macroeconomic factors on the volumes of initial public offerings. Method: This study uses a quantitative method were macroeconomic factors will be used as predictors in a multiple regression analysis. Further, IPO volumes of real estate firms will be considered as the constant. Theorethical references: The basic theories that are used in this thesis are Efficient Market Hypothesis, the FDW-model, and The Capital Demand Hypothesis. Previous thesis that covers IPOs are considered as the fundmental basis of this study. Results: The results shows a negative correlation between the IPO volumes of real estate firms, and the interest rate, as well as the economic cycle. Hence, this study finds a positive correlation between stock prices and the volatility at the stock market. The results don’t find any significant correlation between IPO volumes and the inflation rate.

Thesis, Södertörn University College, School of Business Studies, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:sh:diva-762.
Full textBackground: Within real estate companies assets according to IFRS/ IAS 40 should be valued at fair value, to compare with previous valuation criteria according to which real estate should valued at cost. Two models can be used within IAS 40, these are value at cost and fair value. When valued at cost the real estate value in the balance sheet should be specified at cost. The method chosen by the company should be used for all real estate within the company except for the premises used by the company.
Purpose: The purpose of the study is to analyse and evaluate how real estate companies experienced the problems that arose when converting to IAS 40, and to analyse the effects on the companies key ratios as a result of the change of accounting method. Key ratios examined were, return on equity, solvency ratio, P/E-ratio and debt/equity ratio.
Method: The essay is made on a qualitative effort in the form of four interviews with experts within the chosen subject area. The compilation of key ratio is made in a quantitative form and is made up of secondary data. Conclusions: With the implementing of IAS 40 for real estate accounting, the ability to better compare the accounting between real estate companies increased, even though all companies do not account for their real estate in the same way. It appeared that the regulation requirements need to be adjusted and formed in a way that better matches the reality in which real estate companies act. Valuation with fair value proved to have both advantages and disadvantages. The advantage was that the comparability and the fair picture between real estate companies increased. The disadvantage was that the valuation of the fair value gives an increased risk for the real estate companies to be over- or undervalued. A wrong valuation gives a wrong picture of the real estate companies and effects the key ratios in a volatile manner.

Full textIn this thesis, an efficient Reduced Order Modeling (ROM) technique with control of accuracy for parameterized Finite Element solutions is proposed. The ROM methodology is usually necessary to drastically reduce the computational time and allow for tasks like parameter analysis, system performance assessment (aircraft, complex process, etc.). In this thesis, a ROM using Proper Orthogonal Decomposition (POD) will be used to build local models. The “model” will be considered as a database of simulation results store and retrieve the database is studied by extending the algorithm In Situ Adaptive Tabulation (ISAT) originally proposed by Pope (1997). Depending on the use and the accuracy requirements, the database is enriched in situ (i.e. online) by call of the fine (reference) model and construction of a local model with an accuracy region in the parameter space. Once the trust regions cover the whole parameter domain, the computational cost of a solution becomes inexpensive. The coupled POD-ISAT, here proposed, provides a promising effective ROM approach for parametric finite element model. POD is used for the low-order representation of the spatial fields and ISAT for the local representation of the solution in the design parameter space. This method is tested on a Engineering case of stationary air flow in an aircraft cabin. This is a coupled fluid-thermal problem depending on several design parameters (inflow temperature, inflow velocity, fuselage thermal conductivity, etc.). For evolution problems, we explore the use of time-parallel strategies, namely the parareal algorithm originally proposed by Lions, Maday and Turinici (2001). A quasi-Newton variant of the algorithm called Broyden-parareal algorithm is here proposed. It is applied to the computation of the gas diffusion in an aircraft cabin. This thesis is part of the project CSDL (Complex System Design Lab) funded by FUI (Fond Unique Interministériel) aimed at providing a software platform for multidisciplinary design of complex systems

Full textDenna avhandling behandlar flödet i rörkrökar och radiella turbiner som vanligtvis återfinns i en förbränningsmotor. Utvecklingsfasen av förbränningsmotorer bygger mer och mer på att simuleringar är ett viktigt komplement till experiment. Detta beror delvis på minskade utvecklingskostnader men även på kortare utevklningstider. Detta är en av anledningarna till att man behöver mer exakta och prediktiva simuleringsmetoder. Genom att använda mer komplexa beräkningsmetoder så kan både nogrannheten och prediktiviteten öka. Nackdelen med att använda mer sofistikerade metoder är att beräkningstiden ökar, vilket medför att sådana verktyg är mindre attraktiva för standardiserade design ändamål. Härav, ett av målen med projektet har varit att bidra med att bedöma och förbättra de enklare metodernas prediktionsförmåga som används utav industrin. Genom att jämföra resultat från experiment, Reynolds Averaged Navier-Stokes (RANS) och Large Eddy Simulations (LES) så kan nogrannheten hos de olika simuleringsmetoderna fastställas. Fördelarna med att använda LES istället för RANS när det gäller de undersökta flödena kommer ifrån det instationära flödet i grenröret. När denna instationäritet överlappar den naturligt förekommande turbulensen så saknar modellen en rationell grund. Denna avhandling behandlar effekten av de cykliska flöderna på de valda numeriska modellerna. LES beräkningarna har bevisats kunna förutsäga medelfältet och fluktuationerna väldigt väl när man jämför med experimentell data. Effekterna som den pulserande avgasströmning har på turboladdarens turbin prestanda har också kunnat fastställas. Både konstant och pulserande inlopps randvillkor har används för turbinfallet, där det senare är ett mer realistiskt representation av den riktiga strömningsbilden innuti avgasgrenröret och turbinen. Resultaten har analyserats på flera olika sätt: snabba Fourier transformer (FFT) i enskilda punkter, medelvärden och statistik på problinjer, area och volumsbaserade metoder så som Proper Orthogonal Decomposition (POD) samt Dynamic Mode Decomposition (DMD).

Full textLa tesis explora la viabilidad del método de reducción de modelos Proper Generalised Decomposition (PGD) como herramienta habitual en un entorno industrial para obtener soluciones de problemas de flujo viscoso incompresible que dependan de parámetros. En este documento, partiendo de las ecuaciones que modelan el flujo viscoso e incompresible, se describe en detalle la formulación en forma separada, espacio-parámetros, de las ecuaciones para el método PGD, se desarrolla el algoritmo de resolución teniendo en cuenta los parámetros, se detalla como realizar la implementación en OpenFOAM, que es un software comercial de dinámica de fluidos computacional (CFD por sus siglas en inglés) y se discuten las validaciones numéricas correspondientes. Como paso previo para probar la viabilidad de la PGD a problemas de interés, se estudian flujos de Stokes y Oseen con datos parametrizados. De esta forma, se desarrollan las bases para la construcción de una aproximación separada, espacio-parámetros, de la solución numérica velocidad-presión, todo ello implementado en OpenFOAM. Para estas formulaciones se valida la aproximación numérica de la estrategia desarrollada con ejemplos cuya solución analítica es conocida, lo que permite analizar los errores cometidos, y se presentan ejemplos numéricos de referencia ampliamente estudiados en la literatura para mostrar su viabilidad. Seguidamente se consideran las ecuaciones de Navier-Stokes para flujo incompresible, estacionario y laminar de nuevo dependiendo de parámetros de diseño. La implementación no intrusiva de la PGD en OpenFOAM está formulada para obtener integración perfecta de un modelo de orden reducido (ROM por sus siglas en inglés) con un software CFD validado industrialmente. La metodología propuesta explota las estrategias de solución clásicas ya existentes en OpenFOAM para resolver la iteración espacial de la PGD, mientras que la iteración de las funciones que dependen de los parámetros se realiza de forma externa a OpenFOAM (empleando formulaciones basadas en la colocación puntual). La no-intrusividad es crítica para una cualquier estrategia que pretenda emplear la formulación PGD en la práctica diaria de la producción y diseño industrial. Para justificar la metodología propuesta así como su viabilidad, se muestra la solución de problemas de referencia clásicos y habituales en la literatura así como la resolución de un problema de control de flujo parametrizado en una geometría realista de interés para la industria de la automoción. Finalmente, es importante resaltar que se extiende a flujos turbulentos la metodología propuesta para trabajar con la PGD de manera no-intrusiva. Más concretamente, las ecuaciones de Navier-Stokes se complementan con un modelo de turbulencia habitual en aplicaciones industriales: el modelo de Spalart-Allmaras. En este caso, se propone una extensión de la estructura separada de las aproximaciones (velocidad y presión), y se diseña una estrategia PGD para la construcción de una viscosidad turbulenta paramétrica. Se exploran diferentes posibilidades de implementación de la PGD no intrusiva para las ecuaciones de Navier-Stokes para flujo turbulento y dependiendo de parámetros. La estrategia propuesta se aplica a casos de referencia de control de flujo turbulento bien documentados en dos y tres dimensiones.

Full textThe numerical prediction of aeroelastic systems responses becomes unaffordable when parametric analyses with high-fidelity CFD are required. Reduced order modeling (ROM) methods have therefore been developed in view of reducing the costs of the numerical simulations while preserving a high level of accuracy. The present thesis focuses on the family of projection based methods for the compressible Navier-Stokes equations involving deforming meshes in the case of aeroelastic applications. A vector basis obtained by Proper Orthogonal Decomposition (POD) combined to a Galerkin projection of the system equations is used in order to build a ROM for fluid mechanics. Masked projection approaches are therefore implemented and assessed for different test cases with fixed boundaries in order to provide a fully nonlinear formulation for the projection-based ROMs. Then, the ROM is adapted in the case of deforming boundaries and aeroelastic applications in a parametric context.

O BNDES tem o objetivo de financiar empreendimentos que se relacionem com o desenvolvimento do país, sendo uma de suas modalidades o investimento por subscrição de ações. De um lado, tem-se que as regras elaboradas na estruturação societária de uma empresa podem variar de acordo com a origem do financiamento obtido, em função dos interesses que os diferentes investidores procuram proteger a partir da separação entre a sua propriedade e o controle. Por outro lado, o cenário econômico brasileiro passou por mudanças profundas nos últimos 60 anos, já que o modelo de industrialização baseado no dirigismo estatal – que marcou as décadas de 1950 a 1980 – transformou-se com o movimento de desestatização dos anos 1990. O Estado não se afastou da propriedade empresarial, mas atua agora principalmente como acionista minoritário. Hoje, paira dúvida acerca, em primeiro lugar, das reais motivações que levam determinadas empresas a receber participação do Sistema BNDES. Além disso, há pouca compreensão sobre os veículos jurídicos que viabilizam essas relações público-privadas. A partir de algumas pesquisas sobre o banco, conclui-se que a atuação da sua subsidiária de participações, a BNDESPAR, não ultrapassa objetivos de maximização de valor dos seus ativos. Não se descartou, no entanto, que a função do banco de desenvolvimento – incluindo a do seu braço de renda variável – fosse implementar políticas industriais, por mais que falhas pudessem vir a ocorrer nesse intento, reconhecido como um processo experimental. Assim, revelou-se quais interesses as regras de governança corporativa das companhias abertas financiadas pela BNDESPAR por participação acomodam para a subsidiária, elucidando-se importantes características do modelo contemporâneo de atuação empresarial do Estado e lançando-se luz sobre os objetivos que o levam a investir diretamente como acionista no cenário atual. No caso da BNDESPAR, trata-se de agente em busca de equilíbrio entre a maximização de retornos e a política industrial. De uma maneira mais geral, o BNDES procura ser auto-sustentável – como pré-requisito para existir e cumprir sua missão –, tratando sua subsidiária como a principal personagem desse objetivo dentro do Sistema. A BNDESPAR, por sua vez, acabou por se tornar executora de política voltada a apoiar a negociação das companhias brasileiras no mercado de capitais – atividade emanada da sua própria burocracia.
BNDES has the objective of financing projects related to Brazil’s development and equity purchases are one of its types of investment. On one hand, rules drawn up in a company’s corporate governance structure can vary according to the capital’s origin, since different interests that different investors seek to protect emerge from the separation of their property from the corporate control. On the other hand, Brazilian economic scenario went trough deep changes over the last 60 years, considering that the industrialization model based on State intervention, mainstream between the 1950s and the 1980s, was transformed by the privatization movement in the 1990s. This change, however, did not eliminate the State in corporate property: now it only acts more commonly as a minority shareholder. The present time is marked by doubt over the real motivation that leads some companies to receive equity investments by the BNDES System. Besides that, there is a lack of comprehension on the contractual vehicles that structure these public-private relations. Some researches concerning the bank indicate that its subsidiary investments would not undermine the objective for profit maximization. We have not ignored, however, that the development bank function – including its equity arm – might be executing industrial policies, even though failures are likely to occur during this effort, understood here as an experimental process. Thus, the research has revealed which BNDESPAR’s interests are protected through the corporate governance rules of the public traded companies invested, also revealing important features of the contemporary model of the State as an entrepreneur and clarifying some objectives that could lead the institution to purchase equity participations nowadays. BNDESPAR is an agent motivated by a balance pursuit between profit maximization and industrial policy purposes. Broadly speaking, BNDES seeks self-financial sustainability in order to continue and accomplish its mission, seeing its equity arm as the main executor of this objective inside its System. In this search for sustainability, BNDESPAR became executor of a policy effort for stock markets negotiation raised up among its own bureaucracy activities.

Full text[CA] El principal desafiament als motors turbina de gas utilitzats a la aviació resideix en augmentar l'eficiència del cicle termodinàmic mantenint les emissions contaminants per davall de les rigoroses restriccions. Aquest fet comporta la necessitat de dissenyar noves estratègies d'injecció/combustió que radiquen en punts d'operació perillosos per la seva aproximació al límit inferior d'apagat de flama. En aquest context, el concepte Lean Direct Injection (LDI) sorgeix com a eina innovadora a l'hora de reduir els òxids de nitrogen (NOx) emesos per les plantes propulsores dels avions de nova generació. Sota aquest context, aquesta tesis té com a objectius contribuir al coneixement dels mecanismes físics que regeixen el comportament d'un cremador LDI i proporcionar ferramentes d'anàlisi per a una profunda caracterització de les complexes estructures de flux turbulent generades a l'interior de la càmera de combustió. Per tal de dur-ho a terme s'ha desenvolupat una metodología numèrica basada en CFD capaç de modelar el flux bifàsic no reactiu a l'interior d'un cremador LDI acadèmic mitjançant els enfocaments de turbulència U-RANS i LES en un marc Eulerià-Lagrangià. La resolució numèrica d'aquest problema multiescala s'aborda mitjançant la resolució completa del flux al llarg de tots els elements que constitueixen la maqueta experimental, incloent el seu pas pel swirler i l'entrada a la càmera de combustió. Açò es duu a terme a través de dos codis CFD que involucren estratègies de mallat diferents: una basada en la generación automàtica de la malla i en l'algoritme de refinament adaptatiu (AMR) amb CONVERGE i l'altra que es basa en una tècnica de mallat estàtic més tradicional amb OpenFOAM. D'una banda, s'ha definit una metodologia per tal d'obtindre una estrategia de mallat òptima mitjançant l'ús de l'AMR i s'han explotat els seus beneficis front als enfocaments tradicionals de malla estàtica. D'aquesta forma, s'ha demostrat que l'aplicabilitat de les ferramente de control de malla disponibles en CONVERGE com el refinament fixe (fixed embedding) i l'AMR són una opció molt interessant per tal d'afrontar aquest tipus de problemes multiescala. Els resultats destaquen una optimització de l'ús dels recursos computacionals i una major precisió en les simulacions realitzades amb la metodologia presentada. D'altra banda, l'ús d'eines CFD s'ha combinat amb l'aplicació de tècniques de descomposició modal avançades (Proper Orthogonal Decomposition and Dynamic Mode Decomposition). La identificació numèrica dels principals modes acústics a la càmera de combustió ha demostrat el potencial d'aquestes ferramentes al permetre caracteritzar les estructures de flux coherents generades com a conseqüència del trencament dels vòrtex (VBB) i dels raigs fortament arremolinats presents al cremador LDI. A més, la implantació d'estos procediments matemàtics ha permès recuperar informació sobre les característiques de la dinàmica del flux i proporcionar un enfocament sistemàtic per tal d'identificar els principals mecanismes que sustenten les inestabilitats a la càmera de combustió. Finalment, la metodologia validada ha sigut explotada a traves d'un Diseny d'Experiments (DoE) per tal de quantificar la influència dels factors crítics de disseny en el flux no reactiu. D'aquesta manera, s'ha avaluat la contribución individual d'alguns paràmetres funcionals (el nombre de pales del swirler, l'angle de les pales, l'amplada de la càmera de combustió i la posició axial de l'orifici de l'injector) en els patrons del camp fluid, la distribució de la mida de gotes del combustible líquid i l'aparició d'inestabilitats en la càmera de combustió mitjançant una matriu ortogonal L9 de Taguchi. Aquest estudi estadístic és un bon punt de partida per a futurs estudis de injecció, atomització i combustió en cremadors LDI.
[EN] Aeronautical gas turbine engines present the main challenge of increasing the efficiency of the cycle while keeping the pollutant emissions below stringent restrictions. This has led to the design of new injection-combustion strategies working on more risky and problematic operating points such as those close to the lean extinction limit. In this context, the Lean Direct Injection (LDI) concept has emerged as a promising technology to reduce oxides of nitrogen (NOx) for next-generation aircraft power plants In this context, this thesis aims at contributing to the knowledge of the governing physical mechanisms within an LDI burner and to provide analysis tools for a deep characterisation of such complex flows. In order to do so, a numerical CFD methodology capable of reliably modelling the 2-phase nonreacting flow in an academic LDI burner has been developed in an Eulerian-Lagrangian framework, using the U-RANS and LES turbulence approaches. The LDI combustor taken as a reference to carry out the investigation is the laboratory-scale swirled-stabilised CORIA Spray Burner. The multi-scale problem is addressed by solving the complete inlet flow path through the swirl vanes and the combustor through two different CFD codes involving two different meshing strategies: an automatic mesh generation with adaptive mesh refinement (AMR) algorithm through CONVERGE and a more traditional static meshing technique in OpenFOAM. On the one hand, a methodology to obtain an optimal mesh strategy using AMR has been defined, and its benefits against traditional fixed mesh approaches have been exploited. In this way, the applicability of grid control tools available in CONVERGE such as fixed embedding and AMR has been demonstrated to be an interesting option to face this type of multi-scale problem. The results highlight an optimisation of the use of the computational resources and better accuracy in the simulations carried out with the presented methodology. On the other hand, the use of CFD tools has been combined with the application of systematic advanced modal decomposition techniques (i.e., Proper Orthogonal Decomposition and Dynamic Mode Decomposition). The numerical identification of the main acoustic modes in the chamber have proved their potential when studying the characteristics of the most powerful coherent flow structures of strongly swirled jets in a LDI burner undergoing vortex breakdown (VBB). Besides, the implementation of these mathematical procedures has allowed both retrieving information about the flow dynamics features and providing a systematic approach to identify the main mechanisms that sustain instabilities in the combustor. Last, this analysis has also allowed identifying some key features of swirl spray systems such as the complex pulsating, intermittent and cyclical spatial patterns related to the Precessing Vortex Core (PVC). Finally, the validated methodology is exploited through a Design of Experiments (DoE) to quantify the influence of critical design factors on the non-reacting flow. In this way, the individual contribution of some functional parameters (namely the number of swirler vanes, the swirler vane angle, the combustion chamber width and the axial position of the nozzle tip) into both the flow field pattern, the spray size distribution and the occurrence of instabilities in the combustion chamber are evaluated throughout a Taguchi's orthogonal array L9. Such a statistical study has supposed a good starting point for subsequent studies of injection, atomisation and combustion on LDI burners.

Full textThe dissertation aimed to point out that the methods of the protection of minority shareholders in Chinese law and in French law are not subject to the different criteria. In company limited by shares, the legal provisions intend to find a balance of relation between majority shareholders and minority shareholders, and between the shareholders and the company or group of company. It is corporate profits and the principal of equality that direct legislators and judges to suggest applicable solutions.It is important to notify that in French law, legal provisions about the responsibility of majority shareholders or company leaders and the ways of resort of minority shareholders provide reference for improvement of Chinese law. Besides, the study of acquisition of chinese listed companies, looked from the angle of the protection of minority shareholders, very different from tender offer in French law, demonstrate the characteristics of Chinese stock market and deserve foreign investors’ enough attention

These theses whether examine the property stock investors are overconfident or underconfident. This thesis firstly use VAR model and the empirical result shows that the property stock investors existed overconfidence investment behavior in the bull market, especially in low-price stock. However, this kind of behavior does not exist in the bear market. The result also shows that most of turnover rate are driven by market return rather than property stock return. this represents investors purchase (or sell) the property stock is caused by the market goes up (or down) rather than have perspective in the property stock. The result implied the property stock investor had speculative trading in short term. In long term, investors have insufficient faith in the real estate market. Next, this thesis use EGARCH and the result shows that the overconfidence investors’ excessive trading will increase volatility, and will harm the development of industry. Finally, we discussed the main factor of investors’ underconfidence in property industry, found political environment as well as long recession are the factors.

As the price level soars up, it become more important to study the dynamic relation between stock prices, price indices. In this paper we suspect that property stocks serve as tools of anti-inflation and examine whether there exists a positive correlation between the prices of property stocks and price indices, such as the Rent Index, CPI, and WPI. Our results confirm the positive correlation between the prices of property stocks and the price indices. More precisely, it is revealed by applying VAR and the impulse response analysis that the positive correlation between the prices of property stocks and CPI/WPI in the short run. Using the cointegration analysis, we detect the long-run relation between the prices of property stocks and the Rent Index.

With housing prices continue rising, the government had introduced several housing control measures since 2010 in an effort to strengthen the real estate market. A part of these measures was to limit the lending activities through the Central Bank regulations to suppress rising prices. This study utilizes Event Study Method to analyze if there are negative impacts on listed construction stocks on each of the control measure implemented by the Central Bank. The results indicate that the stock prices of construction stocks would have been impacted when the Central Bank introduce its housing control measures. Specifically, when the Central Bank introduced tighter measures on property and land financing in the targeted areas, investors deem these messages as negative for construction stocks. However, not all measures impact the construction stocks negatively. When the Central Bank announce to raise the rediscount rate, the rate on accommodations with collateral, and the rate on accommodations without collateral, the construction stocks respond positively.

When a Taiwanese company has a lot of real estates, then the company's stock is normally called "asset stock". The thesis puts the focus on exploring the features of systematic risk and return on “asset stock”. Regarding with systematic risk of “asset stock”, there are several findings. Firstly, “asset stock” has a higher average rate of return but with less risk in the past 14 years. That is, “asset stock” is a relatively worthy investment, while compared with “construction stock”. Secondly, the systematic risk on “asset stock” is continuously changing but less volatile. Thirdly, the structural changes in unstable systematic risk on “asset stock” did exist at some particular time points, where big events happened. Therefore, the “big events” help us in explaining the dynamic process of “asset stock returns”. Factors affecting the assets stock return are divided into risk factors, economic factors and big events. In the risk section, the monthly moving average β is used. As for economic factors, the study uses the consumer price index, interest rate, exchange rate, money supply and the stock market index. The regression result shows, the rate of return on stock market has a significant positive impact on "asset stock return", while both interest rate and exchange rate have negative impacts on "asset stock return". Furthermore, the happenings of big events, such as SARs epidemic, and Lehman Brothers' Bankruptcy, hurt the "asset stock return" of the same month. Last but not least, “monthly moving β” is not important in explaining "asset stock returns”. The result remains the same whether the current monthly moving β or the previous month's moving β was used as an explanatory variable.
