The architecture is based on the HTTP protocol, proposing the use of web services technology to interconnect the two network standards. From the installation of a wireless sensor network in a closed environment, its interconnection was performed with the Internet based on the proposed architecture using open standard technologies, the protocol for REST web services and cloud computing structure of the company Amazon Web Services. Information was collected to evaluate the functionality, reliability and system efficiency, accordingly to the ABNT standard, ISO / IEC 9126. The results showed the feasibility of implementing this proposal because it was shown that the interconnection is possible between these network standards using the application layer, reliably, efficiently and with the use of low cost resources. This study might encourage proposals to extend the accessibility of sensor networks to mobile devices. / Este trabalho apresenta uma proposta de arquitetura para interconex?o de redes de sensores sem fio e a Internet utilizando somente a camada de aplica??o, sem que haja a necessidade de altera??o da pilha de protocolos de ambas as redes.

La thèse a parcouru les étapes de l’affirmation progressive d’une véritable politique infrastructurelle européenne cohérente, en examinant trois volets : juridique, institutionnel et financier. Tout d’abord, la thèse a souligné le processus d’autonomisation horizontale (rapport de complémentarité et spécialité vis-à-vis d’autres politiques de l’UE) et verticale («communautarisation ») de la politique de réseaux transeuropéens. En deuxième lieu, l’analyse a mis en évidence le rôle des différents processus d’institutionnalisation et « d’intégration organique » des régulateurs nationaux entrepris par le législateur européen dans la centralisation et la communautarisation de la politique des réseaux. Enfin, la thèse a relevé l’affirmation du caractère central de l’aide financière de l’UE à la création de réseaux, accompagnée par une dérogation partielle des limites imposées par le droit européen aux politiques budgétaires expansionnistes des États membres. / The thesis highlights the development of a coherent and instrumental european infrastructure policy. First, the thesis shows the process of vertical (communitarization) and horizontal (complementarity and specialty vis-à-vis other EU policies) autonomisation of Trans-European Networks (TENs) policy. Secondly, the thesis points out the role played by the processes of « networkation » and « agencification » of national regulators in promoting interconnection and access to networks. Finally, the thesis emphasises the growing relevance of EU financial support to the establishment of TENs, and a competing tendency towards the reconciliation of national expansionary fiscal policy with EU law constraints. The thesis concludes by noting that Member States will continue to play a decisive role in TENs policy, not only by improving the actual degree of its implementation, but also allowing, in a forthcoming Treaty revision, to overcome the TENs intergovernmental legacy. / Le reti transeuropee sono uno dei vettori della competitività, dell’integrazione e dello sviluppo sostenibile dell’Unione. La tesi mette in luce la progressiva affermazione di una coerente politica infrastrutturale europea a carattere strumentale, esaminando tale evoluzione sotto tre profili: normativo, istituzionale e finanziario. In primo luogo, sotto il profilo normativo, la tesi evidenzia, da un lato, la progressiva emancipazione delle istituzioni dell’Unione dall’influenza degli Stati membri nell’esercizio delle proprie competenze in materia di reti transeuropee e, dall’altro, lo sviluppo di relazioni di complementarietà e specialità tra la politica di reti e altre politiche dell’Unione (capitoli 1 e 2). L’elaborato sottolinea, in secondo luogo, sotto il profilo istituzionale, il ruolo del processo di «integrazione organica» dei regolatori nazionali e del processo di «agenzificazione» nel perseguimento degli obiettivi di interconnessione e accesso alle reti nazionali. La tesi osserva, infine, sotto il profilo finanziario, l’accresciuta importanza del sostegno finanziario dell’UE alla costituzione delle reti, che si è accompagnata al parziale superamento dei limiti derivanti dal diritto dell’UE alla politiche di spesa pubblica infrastrutturale degli Stati membri. Da un lato rispetto al diritto della concorrenza e, in particolare, al divieto di aiuti di stato, grazie al rapporto funzionale tra reti e prestazione di servizi di interesse economico generale, e dall’altro lato riguardo ai vincoli di bilancio, attraverso un’interpretazione evolutiva della cd. investment clause del Patto di stabilità e crescita. La tesi, in conclusione, rileva gli sviluppi decisivi della politica di reti europea, ma sottolinea il ruolo che gli Stati membri sono destinati a continuare ad esercitare nel suo sviluppo. Da questi ultimi, infatti, dipende la concreta attuazione di tale politica, ma anche il definitivo superamento, in occasione di una prossima revisione dei Trattati, dei retaggi intergovernativi che continuano a caratterizzare il diritto primario in materia.

Denial of service attacks (DoS) are a common threat to many online services. These attacks aim to overcome the availability of an online service with massive traffic from multiple sources. By spoofing legitimate users, an attacker floods a target system with a high quantity of packets or connections to crash its network resources, bandwidth, equipment, or servers. Packet filtering methods are the most known way to prevent these attacks via identifying and blocking the spoofed attack from reaching its target. In this project, the extent of the DoS attacks problem and attempts to prevent it are explored. The attacks categories and existing countermeasures based on preventing, detecting, and responding are reviewed. Henceforward, a neural network learning algorithms and statistical analysis are utilized into the designing of our proposed packet filtering system.

The Czech Republic has committed itself to adopt the euro with joining the European union in 2004. Until today there has not been any political interest of setting the specific date of euro adoption due to low public approval. Currently, there is an increase of positive public opinion about euro so it is the right time to start an objective discussion. The thesis is divided into three parts. The First part describes the history and evolution of the European monetary union, Maastricht convergence criteria and the theory of optimal currency area. The second part presents possible economic benefits and costs of joining the monetary union. The third and the main part examines the real effects of euro adoption on sample of selected countries with similar characteristics. The impact of euro on main economic indicators was analysed and there has been carried out a comparison between these countries. Also the role of euro in trade of selected countries has been highlighted. Last but not least, the possible impact of euro on country competitivness has been analysed in the context of optimum currency area theory. It is expected that joining the monetary union leads to a boost of bilateral trade which harmonizes the economic cycles of trade partners. The main purpose of this part is to prove the increase of competitiveness of exporters gained from monetary union measured by the raise of the bilateral trade interconnection. Finally these two criteria - gross domestic product alignment and bilateral trade interconnection have been used to describe the suitability of Czech Republic as a candidate country for the European monetary union.

The automation of industrial processes has been one of the greatest innovations in the industrial sector. It allows faster and accurate operations of production processes while producing more outputs than old manual production techniques. In the beverage industry, this innovation was also well embraced, especially to improve its bottling processes. However it has been proven that a continuous optimization of automation techniques using advanced and current trend of automation is the only way industrial companies will survive in a very competitive market. This becomes more challenging for small to medium scale enterprises (SMEs) which are not always keen in adopting new technologies by fear of overspending their little revenues. By doing so, SMEs are exposing themselves to limited growth and vulnerable lifecycle in this fast growing automation world. The main contribution of this study was to develop practical and affordable applications that will optimize the bottling process of a SME beverage plant by combining its existing production resources to basic principles of the current trend of automation, Industry 4.0 (I40). This research enabled the small beverage industry to achieve higher production rate, better delivery time and easy access of plant information through production forecast using linear regression, predictive maintenance using speed vibration sensor and decentralization of production monitoring via cloud applications. The existing plant Siemens S7-1200 programmable logic controller (PLC) and ZENON supervisory control and data acquisition (SCADA) system were used to program the optimized process with very few additional resources. This study also opened doors for automation in SMEs, in general, to use I40 in their production processes with available means and limited cost. / School of Computing / M.Tech (Engineering, Electrical)

In this study the author investigates the nature of compassion, ways of developing compassion within ourselves, and ways of bringing compassion into schools. The author sees an imbalance and disconnection in the current Ontario public school system, between education of the mind (to have) and education of the heart (to be). This is demonstrated in the heightening violence in schools, because violence in schools means that students do not feel connected to and are not happy in their schools. To accomplish this purpose, the author explores the different ways we can connect—within ourselves, with classroom subjects, with students in the school, and with the community at large—through life stories of four holistic educators, including herself. Three have taught in Buddhist, Waldorf, and Montessori schools, which all foster compassion not only through empathy, caring, and love, but also through emotional and moral components of heart education, such as intuition, creativity, imagination, joy (Miller, 2006), and moral education (Noddings, 1992). The enquiry uses qualitative research and narrative method that includes portraiture and arts-based enquiry. The findings in the participants’ narratives reveal that compassion comprises spirituality, empathy, and caring. We can develop compassion through contemplation in an awareness of interconnection between the I and the Other. In conclusion, we can foster compassion in schools if we use holistic education’s basic principles of balance, inclusion, and connection (Miller, 1981, 1993, 1994, 1999, 2000, 2006, 2007, 2010), and if we bring in different ways of fostering compassion that the author has explored through four holistic teachers’ narratives in this study. By nurturing and connecting to students’ hearts, rather than forcing knowledge into their heads, it is possible to create schools where students are happy and feel connected to their learning.

This thesis explores textual and visual images of the EU in South Korea's three prestigious popular newspapers - Chosun Ilbo, Dong A Ilbo and Joong Ang Ilbo - and compares them to the imagery created by the internet versions of these newspapers. In recent years, much scholarly work has been done on the topics of EU imagery in print media, but no systemic attempt has yet been made to EU imagery in internet media. The thesis analyses EU news monitored daily in 12 months of 2008 (a year of the first G20 Summit in Washington and the 6th and 7th rounds of EU-Korea FTA negotiations). This study is interdisciplinary. The thesis draws on several significant theories and concepts from the media studies and linguistics. On top of this, a wide range of approaches of content and visual analysis were reviewed. The study then considers and adopts a multimethodological approach of content analysis (studies by Chaban and Holland) and of visual analysis (by Bain) based on visual semiotics. However, to cope with internet media it also adds several categories which add the notion of interactivity to the original content analysis. It incorporates categories originating from a social semiotic approach (elements of interactive and compositional meta-functions) into the original visual analysis. The results of this study are presented in three case studies. In the first section of each case study the thesis provides a comprehensive overview featuring the latest information and various perspectives (political, economic, social, environmental and developmental). The second section presents formal characteristics of EU images in print newspapers and their internet versions. The third section covers substantive characteristics in both versions. The last section suggests the results of visual analysis. The results of this thesis contribute to two areas of studies: EU external perception studies and internet communication studies: as well as enhancing a deeper understanding of EU-Korea relations.

The cellular operators (Vodacom, Cell C, MTN and now Virgin Mobile) market has over 39-million mobile phone subscribers and the fixed operator (Telkom) has almost 5 million subscribers [13]. Although the telecommunication sector has been experiencing this significant growth (in terms of numbers), monopolisation of the local loop by Telkom has also resulted in communication prices that are not affordable to the majority of South Africans. The government of South Africa has identified cost of telecommunication services as one of the key initiatives that must be addressed to improve equal levels of access to ICT services in general. Local Loop Unbundling (or LLU for short) has been identified by the South African government as a tool that will minimise control that Telkom has over the copper cable connecting exchanges to customers whilst at the same time driving down the costs of Telecommunication in the country. Although some countries have successfully implemented local loop unbundling, some have not been so successful [3]. This dissertation proposes ICT Systems and processes South Africa needs to have in place to become one of the few success stories. The proposed model was validated against the different models adopted in countries like France, Portugal, United Kingdom and Austria. This dissertation develops a model for implementing local loop unbundling in the South African ICT sector. Local loop unbundling (in short LLU) has been successfully (and unsuccessfully) implemented in a number of countries around the world [3]. The model being proposed recommends best practices to be followed by all stakeholders to ensure successful deployment of local loop unbundling. The research takes a closer look at the South African ICT sector and makes recommendations on processes and systems that are necessary to ensure successful deployment of local loop unbundling in South Africa. The dissertation is written from the view of Telkom (The incumbent Operator), competitors (existing ones and new entrants) and the Regulator (ICASA) and focuses mainly on:  Technical Processes and Challenges that must be addressed  Regulatory Process and Challenges that must be addressed  Economic Challenges that must be addressed  Comparison to international ICT Markets and  Recommendations and Conclusions. The dissertation also covers the development of the Local loop unbundling model charter, Local Loop Management website and processes (Annexure A and B) developed (using HTML) used for the management of the unbundling process.
