<p>Progress in miniaturized computing and connectivity has led to a plethora of smart connected electronic devices around humans, leading us towards the era of seamless human-electronics co-operation. In this connected society, radiative communication using electromagnetic fields is the backbone of inter-device connectivity. This unfortunately leads to high power usage as well as physical signals being available for malicious interceptors to snoop. To address the need of security and energy efficiency of inter-device communication for devices on and around the human body, Human Body Communication (HBC) has been proposed. The fundamental philosophy of HBC is to use the human body as a medium - thus being helped and not hurt by the body - for communication between devices. Confinement of a signal within the body implies higher security as well as efficiency. This dissertation is an analysis of these properties of different HBC modalities, through electromagnetic modelling, simulation, and experienced. Electro-quasistatic (EQS) HBC has been explored in significant detail, including a complete theoretical formulation of return path capacitance, as well as a study of inter-body coupling for interference and security management in EQS-HBC. Magnetic modes of HBC have also been analyzed, and compared with its electric counterparts. Finally, a novel HBC technique, GSW-HBC, has been proposed. GSW-HBC or a Goubau line inspired surface wave based HBC, is shown to be a viable, secure and energy efficient alternative to RF wireless communication, leading the search for Gbps communication around the body.</p><p>In reference to IEEE copyrighted material which is used with permission in this thesis, the IEEE does not endorse any of Purdue University's products or services.

The current debates on abolishing hijabs in the European Union have seen many countries absolish headscarves. Nations including France, Belgium, and Austria are among the countries that have banned hijabs in public spaces. However, in Sweden, various bills have been presented in the parliament. The aimed to investigate wheather Hijab and other Islamic covering should be banned in Sweden. The current study adopted a systematic literature review that included 16 studies on the debates about banning the Hijab. The study's findings confirm that the call for a ban on Hijab in Sweden are unjustified and influenced by the oversimplification of the Islamic cultures. Besides, the assertions of the study indicate that the European nations unlawfully targeted Muslims, subjecting them to islamophobia and hate crimes.

This diploma thesis deals with cryptography. It describes its basic allocation and problems of number theory that needs to be addressed. It also deals with methods used to review the formal security of cryptographic protocols from a mathematical point of view. It analyse the tools used to automatic and semi-automatic evaluation of the safety of cryptographic protocols. It describes the process of working with these tools and finally test the security of protocols Kerberos, EKE and Unilateral authentication using symmetric cryptography, HMAC function and hash function. These tests are in tools AVISPA, ProVerif and Scyther. At the end is comparison of results.

The importance of the data authentication has resulted in the science of the data protection. Interest in this knowledge has been growing due to the increase in privacy of the user's identity, especially after the widespread use of online transactions. Many security techniques are available to maintain the privacy of the user's identity. These include password, smart card or token and face recognition or finger print. But unfortunately, the possibility to duplicate the identity of a user is still possible. Recently, specialists used the user's physical location as a new factor in order to increase the strength of the verification of the user's identity. This thesis focused on the authentication-based user's location. It is based on the idea of using the Global Position System in order to verify the user identity. Improving Kerberos protocol using GPS signal is proposed in order to eliminate the effect of replay attack. This proposal does not expect a high performance from the user during the implementation of the security system. Moreover, to give users more confidence to use security protocol, it has to be evaluated before accepting it. Thus, a measurement tool used to validate protocols called BAN logic was described. In this thesis, a new form of BAN logic which aims to raise the efficiency checking process of the protocol protection strength using the GPS signal is proposed. The proposed form of Kerberos protocol has been analysed using the new form of BAN logic. The new scheme has been tested and compared with the existing techniques to demonstrate its merits and capabilities.

Politicians and social marketers considering whether, and how, to implement a national smoking ban in their countries require sound evidence regarding what the causes of support are amongst key stakeholders, how this support will develop over the short to medium term in which they seek to be re-elected, and how support relates to critical outcomes like enforcement. In response to this need, I use structural equation models to develop a model of the antecedents of support, based on theories of self interest and common sense justice, amongst hospitality industry managers. I show that support is determined more by fairness related constructs than self interest constructs, that support for national smoking bans increases consistently over time, and that the initial level of support, and the rate at which support increases, is positively related to subsequent enforcement behaviour by bar managers, in the year after implementation of such a ban, in New Zealand. I use growth mixture modeling to identify two subgroups of bar managers whose support changes at different rates. First, a class of bar managers with a high proportion of smokers who reported fewer instances of respiratory related health problems, showed low initial support, and whose support for the legislation slowly decreased. And second, a class of bar managers comprised of fewer smokers, but reporting more instances of respiratory related health problems. This class began with a high degree support, and steadily increased in support for the national smoking ban. I discuss the implications of these findings for social marketers, health educationalists, and politicians interested in introducing a similar ban in other countries.

This thesis explores why gender hierarchy remains resilient and entrenched in contemporary political life, despite efforts to challenge and transform it. I approach this question by focussing on the reproduction of gendered subjects, which I argue is integral to the reproduction of what I term ‘gender orders’. This reproduction is interrogated through an analysis of the reproduction of homosexuality in the contemporary British armed forces. A review of the literature in feminist International Relations (IR) shows feminists have engaged with poststructural thought to develop sophisticated analyses of the subject as an effect of power. I argue that there might be further resources in post structural thought which could be mobilised to expose the incompleteness and failure of all attempts to reproduce subjectivity which might open up new ways to intervene and subvert gender. Drawing on the thought of Michel Foucault, Jacques Derrida and Judith Butler I develop a critical methodology for analysing the reproduction of gendered subjects in the contemporary British armed forces. I argue that the military gender order is traditionally sustained through the segregation of women and the exclusion of homosexuals. As such it is pervasively heteronormative. For this reason I argue that the potential ‘integration’ of homosexuals did pose a significant threat to the gender order. However I will argue the threat posed by the integration of LGBT personnel has been neutralised by a series of responses which ‘re-inscribe’ them into the gender order, although these responses are always unstable. I demonstrate that gender often fails to guarantee the intelligibility it promises, and attempts to order gender necessarily break down. However I will argue that this cannot be exploited instrumentally in order to subvert gender because the gender order is better characterised as being in perpetual crisis, and any attempt to reproduce gender differently will also be unstable and prone to crisis. Consequently critique then becomes a relentless call to question, undermine and deconstruct all attempts to secure political orders, with no guarantees. Ultimately the thesis demonstrates that gender orders are complex, mobile and resilient and argues that modes of feminist critique need to be similarly mobile and responsive to a constantly shifting discursive terrain.

The purpose of this study was to determine if there is a difference in opinion between chain and franchise restaurant managers and independent owner/operators toward the effects of a smoking ordinance. Results of this study showed a significant statistical difference between restaurateur groups toward the perception of economic effects.

This master thesis was tasked to find out how the parameter of interior atmosphere changes at student's club "Mrtvá Ryba", that means atmospheric aerosols sized from 0,524 to 20 micrometers. This work tries to show indoor aerosols before and after the smoking ban and its comparison. This work describes concentrations PM1 and PM10, and their behavior per day. Concentrations was measured by APS (Aerodynamic particle sizer). The measurement was the first step in the non-smoking club, then processing with retrieved informations in CoPlot, CoStat and Excel, where the statistical method has done, and comparison with previous values. T-tests was used for statistics and linear regresion. The result confirms, what was it supposed to, so concentracion values are significantly different. The average concentration of all measured days (six) of smoking campaign was at PM1 13,28 µg.m-3 and at PM10 23,38 µg.m-3. The average concentration of all measured days (thirty six) of non-smoking campaign was at PM1 4,88 µg.m-3 and at PM10 24,61 µg.m-3. Resulting concentration of aerosol particles was explicity lower at non-smoking period than at smoking period. Contamination of interior enviroment is influenced by many factors. The most important factor is presence of persons and their number, concentration of outdoor...

Current Frame of Religious Freedom in the System of European Protection of Human Rights Abstract This thesis deals with the topic of protection of Freedom of Religion in the System of European Protection of Human Rights. It begins with a description of the formulation of this freedom in the Convention for the Protection of Human Rights and Fundamental Freedoms, Charter of Fundamental Rights of the European Union and the legal systems of Germany, Austria and Czech Republic. The legal systems of Germany and Austria are very close to the Czech one, therefore the acquired knowledge might become an inspiration for considerations of possible future legislative changes in the Czech Republic (also considering that while the integration of other cultures is still a relatively new topic in here, the above mentioned other states have already much more experience on this field). Another reason why this choice was made is also a wide range of interesting court decisions concerning the topic of this thesis mainly in Germany, but also in Austria. The description of the formulation of the Freedom of Religion in general is followed by the theoretical description and praxis of teaching Religion at public schools in the above stated countries. It is obvious from the comparison of the praxis in the aforementioned states that...
