A formal framework is developed and implemented in this research for preliminary rotorcraft design using IPPD methodology. All the technical aspects of design are considered including the vehicle engineering, dynamic analysis, stability and control, aerodynamic performance, propulsion, transmission design, weight and balance, noise analysis and economic analysis. The design loop starts with a detailed analysis of requirements. A baseline is selected and upgrade targets are identified depending on the mission requirements. An Overall Evaluation Criterion (OEC) is developed that is used to measure the goodness of the design or to compare the design with competitors. The requirements analysis and baseline upgrade targets lead to the initial sizing and performance estimation of the new design. The digital information is then passed to disciplinary experts. This is where the detailed disciplinary analyses are performed. Information is transferred from one discipline to another as the design loop is iterated. To coordinate all the disciplines in the product development cycle, Multidisciplinary Design Optimization (MDO) techniques e.g. All At Once (AAO) and Collaborative Optimization (CO) are suggested. The methodology is implemented on a Light Turbine Training Helicopter (LTTH) design. Detailed disciplinary analyses are integrated through a common platform for efficient and centralized transfer of design information from one discipline to another in a collaborative manner. Several disciplinary and system level optimization problems are solved. After all the constraints of a multidisciplinary problem have been satisfied and an optimal design has been obtained, it is compared with the initial baseline, using the earlier developed OEC, to measure the level of improvement achieved. Finally a digital preliminary design is proposed. The proposed design methodology provides an automated design framework, facilitates parallel design by removing disciplinary interdependency, current and updated information is made available to all disciplines at all times of the design through a central collaborative repository, overall design time is reduced and an optimized design is achieved.

Due to the highly-varying wireless channels over time, frequency, and space domains, statistical QoS provisioning, instead of deterministic QoS guarantees, has become a recognized feature in the next-generation wireless networks. In this dissertation, we study the adaptive wireless resource allocation problems for statistical QoS provisioning, such as guaranteeing the specified delay-bound violation probability, upper-bounding the average loss-rate, optimizing the average goodput/throughput, etc., in several typical types of mobile wireless networks. In the first part of this dissertation, we study the statistical QoS provisioning for mobile multicast through the adaptive resource allocations, where different multicast receivers attempt to receive the common messages from a single base-station sender over broadcast fading channels. Because of the heterogeneous fading across different multicast receivers, both instantaneously and statistically, how to design the efficient adaptive rate control and resource allocation for wireless multicast is a widely cited open problem. We first study the time-sharing based goodput-optimization problem for non-realtime multicast services. Then, to more comprehensively characterize the QoS provisioning problems for mobile multicast with diverse QoS requirements, we further integrate the statistical delay-QoS control techniques — effective capacity theory, statistical loss-rate control, and information theory to propose a QoS-driven optimization framework. Applying this framework and solving for the corresponding optimization problem, we identify the optimal tradeoff among statistical delay-QoS requirements, sustainable traffic load, and the average loss rate through the adaptive resource allocations and queue management. Furthermore, we study the adaptive resource allocation problems for multi-layer video multicast to satisfy diverse statistical delay and loss QoS requirements over different video layers. In addition, we derive the efficient adaptive erasure-correction coding scheme for the packet-level multicast, where the erasure-correction code is dynamically constructed based on multicast receivers’ packet-loss statuses, to achieve high error-control efficiency in mobile multicast networks. In the second part of this dissertation, we design the adaptive resource allocation schemes for QoS provisioning in unicast based wireless networks, with emphasis on statistical delay-QoS guarantees. First, we develop the QoS-driven time-slot and power allocation schemes for multi-user downlink transmissions (with independent messages) in cellular networks to maximize the delay-QoS-constrained sum system throughput. Second, we propose the delay-QoS-aware base-station selection schemes in distributed multiple-input-multiple-output systems. Third, we study the queueaware spectrum sensing in cognitive radio networks for statistical delay-QoS provisioning. Analyses and simulations are presented to show the advantages of our proposed schemes and the impact of delay-QoS requirements on adaptive resource allocations in various environments.

本論文主要在討論，先決之爭點與「爭端解決規則與程序瞭解書（DSU）」第六條二項（成立小組請求）間之互動。 首先，作者區別成立小組請求兩大要件，分別為：敘明系爭措施及提供法律根據已釐清系爭案件。 其次，在此架構下，本文進而從近來所發生之四十七個爭端解決案件中，分析上訴機構對兩要件之認定標準的發展。本文發現，爭端解決小組及上訴機構透過放寬先決爭點認定標準之結果，會降低成立小組請求之明確性。同時，本文也蒐集相關實證統計資料，藉以呈現先決爭點如何影響DSU之功能。經由歸納後，本文認為，當前先決之爭點的負面影響大於正面影響。 再者，儘管先決爭點有上述問題，作者一方面仍肯定先決之爭點的正面功能，並認同爭端解決實務放寬認定標準之趨勢；另方面，則嘗試提出若干工具以避免上述負面影響大過正面影響。 最後則提出第六條第二項之修法建議。 關鍵字：爭端解決規則與程序瞭解書（DSU）第六條二項、成立小組請求、先決之爭點 / This thesis focused on the interaction between the preliminary issues and Article 6.2(panel request) of Understanding on Rules and Procedures Governing The Settlement of Disputes(DSU). First, the author distinguished the two main requirements of panel request: identify the specific measures at issue, and provide a brief summary of the legal basis of the complaint sufficient to present the problem clearly. Secondly, with the two requirements as framework, the author started to scrutinize how preliminary issues affected recent 47 dispute settlement cases and analyze its implication. Then, it was observed that the Dispute Settlement Panel and the Appellate Body were broadening their review standards as to preliminary issues, which would then lead to reduce the precision of panel request. Meanwhile, this thesis collected relevant statistic data to show how the preliminary issues affected the current DSU function. Then, it was observed that the preliminary issues, so far, had strong negative effects and few positive effects on the dispute settlement system. Moreover, the author, on the one hand, recognized the function of preliminary issues and viewed current dispute settlement practice as good trend with some deficit; and, on the other hand, tried to propose some useful tools to prevent the negative effect to overcome positive effects. And eventually, proposed revision of Article 6.2 of DSU. Key words: Article 6.2 of Understanding on Rules and Procedures Governing The Settlement of Disputes (DSU), panel request, preliminary issues

The focus of dissertation belongs to the field of learning Czech as a foreign language and deals with the acquisition of pragmatic competence of non-native speakers. Whereas this is a broad area, the work concentrates on speech act request. The aim is to describe how two students of Czech acquired the speech act during a one-year intensive course. The theoretical background is given in Chapter I. The term Interlanguage Pragmatics is introduced to Czech readers. The Chapter further maps what the pragmatic research of non- native speakers generally deals with and what questions it asks. Attention is paid to possible methods for collecting data for research of pragmatic competence, what kinds of errors non- native speakers usually make, what environment is suitable for the acquisition of pragmatic competence or how individual differences among students affects pragmatic competence. In the second chapter attention is paid to speech act request. We present an overview of major longitudinal studies. On the bass of this longitudinal research it was found that students of English go through five stages of development when acquiring request. The stages are presented here in detail. In the research part of the dissertation the investigation of how two non-native speakers (a student from Taiwan and a student...

The thesis investigates the extent to which cross-border taking of evidence in civil and com-mercial matters in relation to Switzerland, South Africa, Botswana, Namibia, Nigeria, and Uganda is allowed. Such evidence-taking is not only governed by the domestic law of the state seeking evidence abroad and that of the state where the relevant means of proof are located, but also by public international law, and more specifically by the concept of sovereignty. The ad-missibility of the cross-border taking of evidence under public international law depends on whether or not evidence-gathering in civil litigation is regarded as a judicial act, which violates sovereignty when performed on foreign territory, or as a purely private act. In the first case, the evidentiary material has to be obtained through channels of international judicial assistance. Such assistance can either be rendered based on the basis of an international treaty, or through courtoisie internationale. No international judicial assistance is necessary in cases of a so-called “transfer of foreign evidence”, provided no compulsion is applied which infringes the sovereignty of the foreign state. The thesis analyses the taking of evidence abroad based on the Hague Evidence Convention, and the Hague Procedure Convention. It further expounds how evidence located in Switzer-land, Botswana, Namibia, Nigeria, and Uganda can be obtained for the benefit of civil proceed-ings pending abroad in the absence of any relevant international treaty. The thesis also exam-ines under what conditions a litigant in civil proceedings in the aforementioned countries may request evidence to be taken on foreign soil. The position of cross-border taking of evidence in civil and commercial matters in the said countries is assessed, and suggestions are made on how such status quo may be improved. The thesis makes an attempt to establish the basic prin-ciples for a convention on evidence-taking in civil and commercial matters between South Af-rica, Botswana, Namibia, Nigeria, and Uganda. The development of such principles, however, is only possible once the similarities and differences in the procedure for the taking of evidence and the means of proof in the relevant laws of the aforesaid countries have been identified. / Public, Constitutional, and International / LL.D.

I chose the topic of my diploma thesis ?Role and Compass and Potential of Non-government Non-profit Organisations when Solving Crisis Situations and System of Co-operation between them and Bodies of Crisis Management? because I believe that non-profit organisations play a key role at providing help to people in distress. I pay high attention to the non-profit organisations which, within their compass, try to help people in distress. They attempt to mitigate the consequences of emergencies or crisis situations, which can affect any human being at any time. It was only when I started studying at the University of South Bohemia and when working for the police that I found out that the non-profit organisations which operate in the Czech Republic depend mainly on the grant policy, sponsorship and human approach of the people who are employed in these organisations or support them in whatever way. Having chosen the topic of my diploma thesis, I have tried to summarize and submit as much information for the readers of this paper to absorb as many data as possible on the non-profit organisations which work within the South-Bohemian region and are available when preparing and solving emergencies and crisis situations. I have made an attempt to describe their role, compass and employment at emergencies. The other objective of my thesis is to describe their communication within the Emergency Services and with the bodies of Crisis Management. The objective of my diploma thesis is to analyse the activities of non-government non-profit organisations when dealing with crisis situations and emergencies. Based on qualitative research, this goal was met. Nowadays, in the time of economic crises both in the Czech Republic and in the world, I must state that to secure funding, material and human resources, which would enable their workers to perform the activities given by their mission, represents for the non-profit organisations a superhuman task. The hypothesis that the system of co-operation of the bodies of Crisis Management and non-profit organisations is sufficient has been confirmed. The hypothesis that the activities of non-profit organisations when dealing with crisis situations and emergencies represent an important factor has been confirmed as well.

Além da aferição do tempo médio de cada uma das etapas previstas na Lei de Recuperação de Empresas (deferimento do processamento da recuperação judicial, concessão da recuperação judicial e encerramento do processo após cumprimento de todas as obrigações previstas no plano que se vencerem até dois anos depois da concessão da recuperação judicial), busco também verificar se, de fato, alguma sociedade requerente conseguiu se recuperar. Para tanto, considerarei recuperada a sociedade que, após o encerramento do processo, estiver cumprindo plenamente o seu plano de recuperação, sem que tenha havido qualquer requerimento posterior de falência. Considerando que a Lei de Recuperação de Empresas já está no seu sétimo ano de vigência, bem como o fato de o legislador ter idealizado o processo para que dure no máximo 3 anos, entendo não haver óbices à adoção do conceito supra, tendo em vista que já haver tempo suficiente para o início e encerramento desse tipo de processo. Diante disso, o presente estudo observou que o tempo médio para cumprimento das etapas ultrapassa o limite do razoável, bem como que nenhuma sociedade conseguiu se recuperar até o desfecho da pesquisa, havendo casos, inclusive, de convolação da recuperação judicial em falência. / This study focus on analyzing the judicial recovery proceedings from its beginning, since The New Business Restructuring and Bankruptcy Law's effectiveness (February of 2005) until June 31st, 2011, when its use started on the enterprise matters court of the State of Rio de Janeiro. The analyzes will be done through all phases predicted on the New Business Restructuring and Bankruptcy Law, such as the acceptance of the process of Judicial Recovery, the granting of the judicial recovery and the closure of the process after fulfillment of all obligations predicted on the recovery plan in the period limit of 2 years after the granting of the judicial recovery plan. This analyzes also confirm if any Company had in fact been able to recover after this process. For this purpose, it shall be considered recovery a Company that has fulfill it plans after the Regarding the 7th anniversary of The New Business Restructuring and Bankruptcy Law closure of the process without a claim of bankruptcy in this period., as well as the Brazilian Legislator planned processing to last no more than three years, from my point of view there are no reasons which can obstruct the referred concept adoption as there is time enough to initiate and conclude the processing. Therefore, this study had observed that average time to conclude all processing stages exceed the reasonable time and there was no company able to recover itself until the closure of this study, having indeed cases of conversion of the Judicial Recovery into bankruptcy.

IEEE 802.11 wireless LANs operating in the infrastructure mode are extremely popular and have seen widespread deployment because of their convenience and cost efficiency. A large number of research studies have investigated the performance of DCF, the default MAC protocol in 802.11 WLANs. Previous studies have pointed out several performance problems caused by the interaction of DCF in infrastructure-based WLANs. This thesis addresses a few of these issues. In the first part of the thesis, we address the issue of head-of-line (HOL) blocking at the Access Point (AP) in infrastructure WLANs. We use a cooperative ARQ scheme to resolve the obstruction at the AP queue. We analytically study the performance of our scheme in a single cell IEEE 802.11 infrastructure WLAN under a TCP controlled file download scenario and validate our analysis by extensive simulations. Both analysis and simulation results show considerable increase in system throughput with the cooperative ARQ scheme. We further examine the delay performance of the ARQ scheme in the presence of both elastic TCP traffic and delay sensitive VoIP traffic. Simulations results show that our scheme decreases the delay in the downlink for VoIP packets significantly while simultaneously providing considerable gains in the TCP download throughput. Next, we propose a joint uplink/downlink opportunistic scheduling scheme for maximising system throughput in infrastructure WLANs. We first solve the uplink/downlink unfairness that exists in infrastructure WLANs by maintaining a separate queue and a backoff timer at the AP for each mobile station (STA). We also increase the system throughput by making the backoff timer a function of the channel gains. We analyse the I performance of our scheme under symmetric UDP traffic with i. i. d. channel conditions. Finally, we discuss several opportunistic scheduling policies which aim to increase the system throughput while satisfying certain Quality of Service (QoS) objectives. The standard IEEE 802.11 DCF protocol only offers best-effort services and does not provide any QoS guarantees. Providing QoS in 802.11 networks with time varying channel conditions has proven to be a challenge. We show by simulations that by an appropriate choice of the scheduling metric in our opportunistic scheduling scheme, different QOS objectives like maximizing weighted system sum throughput, minimum rate guarantees and throughput optimality can be attained.

This diploma thesis is dedicated to the European patent with unitary effect and reviews effects of the approval of the unitary patent package for clarity, time demands and financial aspects of patent protection. The thesis also deals in detail with assessment of changes in the language question in connection with the regulation of translation or in the event of a dispute concerning a European patent with unitary effect. It further assess changes resulting from the ratification of the Agreement on a Unified Patent Court and its impact on financial costs and time demands of patent litigation for the patent applicant. In the practical part the author conducts a party interested in unitary patent protection through the process, procedure for filing and communication with Industrial Property Office and the European Patent Office, from the filing of a application for a Unitary patent until the grant of a Unitary patent.
