[pt] Um dos principais desafios em redes de sensores sem fio (RSSF) é reduzir o consumo de energia dos nós sensores. Um método usado para economizar a bateria que alimenta os nós sensores é o duty cycling (DC) do rádio, onde o rádio fica desligado na maior parte do tempo e fica ligado por pouco tempo para verificar se existe alguma mensagem. O DC é usado com frequência em aplicações de monitoramento onde apenas uma mensagem é transmitida depois da leitura do sensor. Geralmente a leitura do sensor só volta a acontecer depois de minutos, logo poucas mensagens são transmitidas por unidade de tempo. Neste trabalho, analisamos o uso da técnica de DC em um contexto diferente, o da disseminação de código, onde várias mensagens são enviadas em um curto espaço de tempo, e que usa mensagens broadcast, ao contrário do monitoramento, que utiliza mensagens unicast. Analisamos dois algoritmos de disseminação específicos, um para um ambiente de máquinas virtuais executando nos motes, onde o código disseminado é um script com tamanho da ordem de bytes, e outro para disseminação de códigos da aplicação inteira, onde o tamanho é bem maior que no caso do script, da ordem de kbytes. O objetivo deste trabalho foi avaliar qual o impacto do DC na latência e quanto de energia foi economizado quando comparado a deixar o rádio ligado o tempo todo, que é como ambos algoritmos funcionam em sua forma original. / [en] One of the key challenges in wireless sensor networks (WSN) is to save energy at motes. One method to save battery is radio duty cycling (DC), which keeps the radio turned off in most of the time and turns the radio on for a short time to verify if any there are any messages. DC is frequently used in monitoring applications where only one message is transmitted after the mote reads its sensor. Usually the mote reads its sensor only once every few minutes, so few unicast messages are transmitted in the network per time unit. This work analyzes the use of the DC method in code dissemination. In this context, multiple broadcast messages are transmitted in a short time. We examined two specific dissemination algorithms, one of them proposed for a virtual machine environment, in which the disseminated code is a small script, and a second one originally proposed for disseminating the code of an entire application, typically much larger than a script. The objective of this study is to evaluate the impact of DC on latency and how much energy was saved when compared to leaving the radio on all the time, which is how both algorithms work in their original form.

判斷目標公司董事出售公司或控制權的決策是否符合受任人義務是一個困難且重要的問題，因為此種類型的決策董事有可能是出於自身利益也可能是為全體股東利益而為，在此種利益衝突屬於晦暗不明的情況，法院應該要採取怎樣的審查態度一方面可以尊重董事決策的空間，另一方面又可以確保股東的利益被保全，成為本論文最關心的問題。 以我國為例，近年公股銀行民營化或是私募基金收購案例屢見不鮮，共同引發的擔憂就是目標公司董事同意此項併購案到底是因為併購條件有利於全體股東，還是嘉惠特定合作對象而決定？我國企業併購法第5條及第6條要求目標公司董事為併購決議時應盡其注意義務及忠實義務，然董事到底是為「公司」還是「股東」盡其義務似乎仍有疑義；再者，法院似乎亦尚未發展出在個案中判斷董事具體行為是否符合受任人義務的標準，因此本文擬參考美國法上的相關規範，以期解決我國現狀的困境。 德拉瓦州法院在1980年代提出一項標準，當目標公司董事決定要出售公司或控制權時，董事有義務要為股東爭取最好的價格，又稱為「露華濃義務(Revlon Duty)」或「標售公司義務」，有兩個重點值得關注：第一，目標公司董事同意何種併購交易會觸發露華濃義務？此即露華濃適用範圍的討論；第二，目標公司董事一旦觸發露華濃義務，董事應該要採取何種具體措施以符合要求？此即露華濃義務內涵的討論。對應到我國現況，應不應該在特定的併購交易中限縮董事的裁量空間？或提出可供法院參考之指標？

The topic of Limited Liability Company is a popular issue among the professional public due to the fact that Limited Liability Company belongs to the most favourite and the most widespread companies. This thesis comprehensively explains duties of members of Limited Liability Company in terms of Business Corporations Act and, where appropriate, compares them with those contained in the Commercial Code. After the brief discourse about Limited Liability Company, its nature and its position among the business corporations, the thesis provides characteristics of a share with emphasis on its qualitative aspect. In the second chapter the schemes of duties of members in works of various authors are first of all compared and critically assessed, and subsequently the own division of duties of members is created. A criterion for the division of duties is the fact, whether they are governed by general or special regulation and in the latter whether the duties arise on the basis of the act, or the Memorandum of Association. The characteristics of duties itself is included in the third to sixth chapters, which successively explain the duty of loyalty, the contributory duty, the liability duty, the duty of additional contribution, the duty of personal participation on a company, the duty to contribute to the...

Diploma thesis - abstract Due managerial care and diligence as a criterion for the determination of liability (a legal and comparative analysis) Lucie Krtoušová The purpose of this thesis is to critically analyse the interpretation of the concept of the due managerial care and diligence and consider the requirements that a director must comply with. The method used in this paper is the comparative analysis. As a basis of the comparative analysis it is chosen the British concept of fiduciary duties and duty of care, skill and diligence which is compared with the Czech concept of the care of a prudent manager. The thesis is composed of five chapters, each of them dealing with different aspects of the concept of the due managerial care and diligence. Chapter One is introductory and defines basic terminology used in the thesis such as the director, the care of a prudent manager, the duty of loyalty, fiduciary duties and the duty of care, skill and diligence. Chapter Two examines the British concept of fiduciary duties. The chapter consists of five parts. Part One focuses on introduction into the system of general duties of directors. Part Two explains the fiduciary position of a director. Part Three and Four address the two aspects of the duty of loyalty, i.e. the duty to act in the interest of the company and...

A heavy-duty vehicle can benefit from the height control of the chassis that anair suspension provides. For example, to retain a pitch angle parallel to the road,regardless of what load it carries. For the purpose of developing a controller,a model of the air suspension provides evaluation and testing opportunities aswell as it gives the option for more advanced model based controller algorithms.Furthermore, a model can provide with an accurate axle weight estimation. Inthis thesis, both physical and statistical models are developed and parametersare estimated by solving minimization problems. They are then evaluated usingdata collected from a Scania truck, comparing normalized mean-root error valuesas well as residual analysis of each model.

Selected aspects of attorney's duty of confidentiality Abstract One of the attorney's most important duties is the commitment to maintain the confidentiality of information he or she has learned while providing legal services. However, it is not a lawyer's privilege but a commitment to protect the rights and legitimate interests of his or her clients. The duty of confidentiality may be waived exclusively by the client or his legal successor of the client. Restrictions or breaches of this obligation should occur exceptionally, only in defined cases. In recent years, the effort of the legislators and other entities to disclose this duty of confidentiality can be noticed in the Czech Republic. The overall purpose of this thesis is to analyse the legal regulation of attorney's confidentiality in the Czech Republic. This thesis focuses mainly on the regulation contained in the Czech Law of Advocacy, in the relevant provisions of the Czech Criminal Procedure Code and in the professional regulations of the Czech Bar Association. The first two chapters of this thesis are rather of general nature. A significant part is devoted to explanation of the notion of confidentiality, its meaning and its material and personal scope. The third chapter discusses legal exceptions when breaching of attorney's confidentiality is...

Na Teoria dos Sentimentos Morais, Adam Smith estabelece um esquema pluralista para explicar a aprovação moral, com quatro tipos de juízos morais: 1) em relação ao motivo da ação, o juízo que determina a conveniência ou inconveniência (propriety ou impropriety); 2) em relação aos efeitos imediatos da ação, o juízo determina seu mérito ou demérito; 3) ao analisar o acordo entre o ato e determinada regra geral de conduta, o juízo determina se o indivíduo agiu de acordo com seu dever; e 4) em relação aos efeitos não imediatos do ato, isto é, à maneira como esse ato se insere no funcionamento global da sociedade (juízo que Smith analisa sob o nome de aparência de utilidade). Esses quatro tipos de juízos se fundam na imaginação e formam a totalidade do princípio de aprovação que estrutura a parte especulativa de sua teoria moral. / In The Theory of Moral Sentiments, Adam Smith establishes a pluralist scheme to explain moral approbation, with four kinds of moral judgments: 1) regarding the motives of the agent, the judgment determines its propriety or impropriety; 2) regarding the immediate effects of the action, the judgement determines its merit or demerit; 3) analyzing if this act is a particular case of a general rule, the judgement determines if the agent has acted according to his duty; and 4) regarding the remote effects of the action, that is, the way this action is a part of the global operations of society (a judgement that Smith calls the appearance of utility). These four kinds of moral judgments are grounded in imagination and form the totality of the principle of approbation that structure the speculative part of his moral philosophy.
