Avhandlingen tar sin utgångspunkt i två uppslagsord i Svenska Akademiens Ordlista 2006: bautasten och bauta-. Övergripande syfte är att beskriva och förklara lexikala förändringar hos ord bildade med bauta(-) i svenskan under perioden 1664–2006, med särskild hänsyn till dessa förändringars relation till ordens etableringsgrad. Materialet består av 838 belägg för ord bildade med baut- eller böt-, och därutöver undersöks 30 ordböcker. Ordet bautasten är ett isländskt lånord i svenskan. Undersökningen av fornvästnordiska ord visar att bautasteinn kan vara ’sten som är slagen ned i jorden’ eller ’sten rest över en fallen krigare’, två betydelser som kan sammanföras i betydelsen ’minnessten’. Denna betydelse framträder också tydligt i samtliga texter. Historiens höga status under stormaktstiden har haft stor betydelse för att ordet bautasten lånades in i svenskan år 1664. Språkstrukturella faktorer har sannolikt lett till att ordet har uppmärksammats och att det har kunnat användas i svenskan. Under perioden 1664–1790 har etableringsgraden hos bautasten inte har varit hög, men vissa tecken tyder på att den höjs under perioden. Fram till ca 1900 stiger etableringsgraden hos bautasten, men den avtar sedan fram till 1973. I avhandlingen antas att ordets växlande etableringsgrad har varit beroende av synen på historien. I början av 1970-talet stiger etableringsgraden åter hos bautasten och 1985 finns första belägget för bauta- som förstärkande förled, vilket med stor sannolikhet har sin orsak att söka hos den stora populariteten hos och spridningen av seriealbumet Asterix. Förleden bauta- har visat sig vara mycket användbar som förstärkande förled. I materialet finns 3 ord bildade med bauta(-) som inte är etablerade i språksamfundet. / The starting point for the dissertation is two entry words in Svenska Akademiens Ordlista (SAOL 13, 2006): bautasten and bauta-. The overall purpose is to describe and explain lexical changes in words created with bauta(-) in the Swedish language during 1664–2006, placing particular em¬phasis on these changes in relation to the degree of establish¬ment. The material consists of 838 pieces of evidence of words created with baut- or böt- and, in addition, 30 dictionaries are exam¬ined. The word bautasten (‘menhir’, ‘standing stone’) is an Icelandic loan word in the Swedish lan¬guage. The examination of Old West Norse words shows that bautasteinn can be ’sten som är slagen ned i jorden’ (‘stone beaten into the ground’) or ’sten rest över en fallen krigare’ (‘stone erected over a fallen warrior’), two meanings which can be brought together in the meaning ’minnessten’ (‘memorial monument’). This meaning also clearly appears in all texts. The high status of history during the Swedish Age of Greatness was significant for the inclu¬sion of the word bautasten into the Swedish language in 1664. Language-structural factors have likely lead to the word being noticed as well as made it possible to use in the Swedish language. During 1664–1790, the degree of establishment of bautasten was not high, but there are indi¬cations that it increased during the period. Until about 1900, the degree of estab¬lish¬ment of bautasten increased, but then it decreased up until 1973. In the disserta¬tion it is assumed that the varying degree of establishment has been dependent on the view of history. In the beginning of the 1970s, the degree of establishment of bautasten increased once again and in 1985, the first instance of bauta- as an augmentative prefix appears, which most likely can be attributed to the great popularity and wide spread of the cartoon magazine Asterix. The prefix bauta- has proven to be very usable as an augmentative. There are 3 words created with bauta(-) in the material that are not established in the language community

There are several standards for wireless communication. People that are involved in computers and networking recognize names like Bluetooth, HiperLAN and IEEE 802.11. The last one was standardized in 1997 [2,6]and has begun to reach acceptance as a solid ground for wireless networking. A fundamental part of an IEEE 802.11 node is the Medium Access Controller, or MAC. It establishes and controls communication with other nodes, using a physical layer unit. The work has been carried out as final project at Linkopings Universitet, it has been about the improvement of the functions of MAC layer. I have developed some of the required functions that PUM uses to interact with the MAC layer. Because of that, I have implemented the Reception functions of MAC layer, having the possibility of using short control frames RTS/CTS to minimize collision.

The aim of this study is to show how a possible philosophy of life can arise from Bergson&rsquo / s conception of time. In realizing this aim, I appeal to Hadot&rsquo / s description of the paradox of the human condition. I claim that in order to understand how a Bergsonian philosophy of life through Bergson&rsquo / s conception of time would arise we need to understand the paradox of the human condition. The reason for this is that there are a lot of dualities in Bergson&rsquo / s philosophy all of which, I claim, are based on this fundamental duality concerning the human condition. I believe that when this paradox and its possible resolution are restated in Bergsonian notions, a Bergsonian philosophy of life that consists of a life sub specie durationis, that is a life under the aspect of duration, would arise. Hadot considered the paradox within the context of phenomenology alone. This made me proceed by searching for other approaches to the paradox within Bergson&rsquo / s philosophy. I realized that the attempts in finding out possible solutions to this problem cannot be found in the context of phenomenology alone and that the vitalist and the existentialist aspects have to be considered in order to remain faithful to Bergson&rsquo / s philosophy as well as in order to construct a Bergsonian philosophy of life. The phenomenological aspect of the paradox arises around Bergson&rsquo / s notion of displacement of attention and when the notion of dur&eacute / e r&eacute / elle is considered with consciousness in the light of the notion of intensity. The vitalist aspect enters into our discussion when we analyze Bergson&rsquo / s notion of &eacute / lan vital around the consideration of true evolution. I believe that the existentialist aspect of the paradox of the human condition comes from Bergson&rsquo / s notion of freedom around the discussion of the superficial and the fundamental self. It emerges if the individual asks himself how to deal with this paradox that in turn defines his struggle to transform the tension the paradox involves and that tells him to bring his own attitude towards it.

In recent years, immense effort has been channelled towards the Information and Technological development of rural areas. To support this development, telecommunication networks have been deployed. The availability of these telecommunication networks is expected to improve the way people share ideas and communicate locally and globally, reducing limiting factors like distance through the use of the Internet. The major problem for these networks is that very few of them have managed to stay in operation over long periods of time. One of the major causes of this failure is the lack of proper monitoring and management as, in some cases, administrators are located far away from the network site. Other factors that contribute to the frequent failure of these networks are lack of proper infrastructure, lack of a constant power supply and other environmental issues. A telecommunication network was deployed for the people of Dwesa by the Siyakhula Living Lab project. During this research project, frequent visits were made to the site and network users were informally interviewed in order to gain insight into the network challenges. Based on the challenges, different network monitoring systems and other solutions were deployed on the network. This thesis analyses the problems encountered and presents possible and affordable solutions that were implemented on the network. This was done to improve the network‟s reliability, availability and manageability whilst exploring possible and practical ways in which the connectivity of the deployed telecommunication network can be maintained. As part of these solutions, a GPRS redundant link, Nagios and Cacti monitoring systems as well as Simple backup systems were deployed. v Acronyms AC Access Concentrators AMANDA Automatic Marylyn Network Disk Archiver CDMA Code Divison Multiple Access CGI Common Gateway Interface.

Este trabalho busca verificar, por meio da análise do processo de criação e implementação do Cadastro Ambiental Rural a partir da perspectiva da democracia deliberativa de Habermas, a possibilidade de tal instrumento se transformar em objeto de políticas públicas que proporcionem uma proteção ambiental efetiva. Tenciona também investigar as finalidades do CAR enquanto instrumento da Administração Pública em suas funções reativa e proativa, utilizando como abordagem a contextualização do referido instrumento, incluindo questões relativas ao Código Florestal de 2012, lei na qual está inserido, para posteriormente descrever seus diferentes aspectos. Estes compreendem o CAR como materialização do direito à informação ambiental, sua função de combate ao desmatamento e pressuposto do Programa de Regularização Ambiental, além de seu papel no zoneamento ambiental. Também é feita uma análise do processo de implementação do Cadastro Ambiental Rural em Caxias do Sul à luz da teoria de Habermas, da qual são explicitados elementos referentes ao procedimento, princípios e formas de aplicação. A metodologia adotada é a hipotético-dedutiva, utilizando as técnicas de pesquisa bibliográfica e documental. Como resultados da pesquisa, destacam-se a constatação acerca da multiplicidade de potencialidades do CAR, que pode servir de base para diferentes ações e políticas de proteção ambiental, assim como a real possibilidade e urgente necessidade de ampliar, aprimorar e consolidar mecanismos deliberativos na tomada de decisões públicas, bem como na implementação de políticas públicas de cunho ambiental no Brasil. / This work seeks to check, through the analysis of the process of creation and implementation of the Rural Environmental Registry from Habermas deliberative democracy perspective, the possibility of this tool to become an object of public policy, providing an effective environmental protection. It also aims to investigate the goals of the Rural Environmental Registry as a tool of Public Administration in its reactive and proactive functions, using as approach its context, including issues about the Forest Code of 2012, law in which the Rural Environmental Registry is envisaged, to later describe its main aspects. These include the Rural Environmental Registry as embodiment of the right to environmental information, its function in the fight against deforestation and as requisite for joining the Program for Environmental Regularization, besides its roll in the environmental zoning. It is also done an analysis of the process of implementation of the Rural Environmental Registry in Caxias do Sul under the perspective of Habermas theory. In this context, the work explains elements about the procedure, principles and forms of execution of this theory. It is adopted the hypothectical-deductive methodology, using bibliographic and documentary techniques. As results of this research, it is possible to highlight the conclusion about the multiplicity of potentialities of the Rural Environmental Registry that may become a basis for several actions and environmental protection policies, such as the real possibility and urgent necessity of expanding, improving and consolidating deliberative mechanisms in the taking of public decisions, as well as in the implementation of environmetal public policy in Brazil.

Wireless networks have potential applications in wireless Internet connectivity, battlefields, disaster relief, and cyber-physical systems. While the nodes in these networks communicate with each other over the air, the challenges faced by and the subsequent design criteria of these networks are diverse. In this thesis, we study and discuss a few design requirements of these networks, such as efficient utilization of the network bandwidth in IEEE 802.11 infrastructure networks, evaluating utility of sensor node deployments, and security from eavesdroppers. The presence of infrastructure IEEE 802.11 based Wireless Local Area Networks (WLANs) allows mobile users to seamlessly transfer huge volumes of data. While these networks accommodate mobility, and are a cost-effective alternative to cellular networks, they are well known to display several performance anomalies. We study a few such anomalies, and provide a performance management solution for IEEE 802.11 based WLANs. On the other hand, in sensor networks, the absence of infrastructure mandates the use of adhoc network architectures. In these architectures, nodes are required to route data to gateway nodes over a multi-hop network. These gateway nodes are larger in size, and costlier in comparison with the regular nodes. In this context, we propose a unified framework that can be used to compare different deployment scenarios, and provide a means to design efficient large-scale adhoc networks. In modern times, security has become an additional design criterion in wireless networks. Traditionally, secure transmissions were enabled using cryptographic schemes. However, in recent years, researchers have explored physical layer security as an alternative to these traditional cryptographic schemes. Physical layer security enables secure transmissions at non-zero data rate between two communicating nodes, by exploiting the degraded nature of the eavesdropper channel and the inherent randomness of the wireless medium. Also, in many practical scenarios, several nodes cooperate to improve their individual secrecy rates. Therefore, in this thesis, we also study scenarios, where cooperative schemes can improve secure end-to-end data transmission rates, while adhering to an overall power budget. In spite of the presence of voluminous reservoirs of information such as digital libraries and the Internet, asking around still remains a popular means of seeking information. In scenarios where the person is interested in communal, or location-specific information, such kind of retrieval may yield better results than a global search. Hence, wireless networks should be designed, analyzed and controlled by taking into account the evolution of the underlying social networks. This alliance between social network analysis and adhoc network architectures can greatly advance the design of network protocols, especially in environments with opportunistic communications. Therefore, in addition to the above mentioned problem, in this thesis, we have also presented and studied a model that captures the temporal evolution of information in social networks with memory.

This report describes a thesis work carried out at ABB Robotics in Västerås. The objective of this thesis is to find technologies  and equipments  for wireless data transfer  suitable for the present and future needs of ABB Robotics Remote Service for large installations in industrial environments. ABB Robotics has a Remote Service solution to securely gather information from robots, manage alarms and potentially execute remote commands by ABB Robotics. This solution consists of an intelligent Service  Box plugged to the robot. This  Service Box is also connected through GPRS or directly through Internet to create a secure VPN connection to a central Remote Service  server. The Remote Service Box is well  suited  for small customers with  1-10 robots with plug  and play installation, but show limitations at a larger scale of deployment  due to equipment costs,  network and installation complexity. A new Service Box is planned that will accommodate future added functionality to Remote Service. This Service Box will require new network solutions as the added functionality  is depending on a higher bandwidth than the GPRS networks can deliver. I have surveyed most existing  wireless  networking technologies  and  analyzed  them  withrespect  to function, cost and availability which provide a knowledge base that makes it possible to find  suitable  solutions. When the most suitable technologies are identified a survey was performed to find equipments that meet the requirements at the lowest cost. A new hierarchical network topology is proposed  that will lead to cost savings by replacing multiple WAN connections in the present solution with  a network switch and  single WAN connection to Internet. As manufacturers of network equipments for industrial environments are relatively few, alternative solutions were also investigated in order to find the most cost effective solutions. The  proposed  network topology together with the data from the surveys lead to recommendations on using Wi-Fi  in the wireless LAN and  a  3G mobile  network for the WAN connection to Internet, as well as recommendations on alternative network equipments that  potentially  can  lead to substantial savings when the new network solutions are implemented.

Nous appliquons la théorie asymptotique des expériences statistiques à des problèmes liés aux valeurs extrêmes. Quatre modèles semi-paramétriques sont envisagés. Tout d'abord le modèle d'échantillonnage de fonction de répartition de type Pareto. L'index de Pareto est le paramètre d'intérêt tandis que la fonction à variation lente, qui intervient dans la décomposition de la fonction de survie, joue le rôle de nuisance. Nous considérons ensuite des observations i.i.d. de fonction de répartition de type Weibull. Le troisième modèle étudié est un modèle de régression. On considère des couples d'observations $(Y_i,X_i)$ indépendants, les v.a. $X_i$ sont i.i.d. de loi connue et on suppose que la fonction de répartition de la loi de $Y$ conditionnellement à $X$ est de type Pareto, avec une fonction à variation lente et un index $gamma$ qui dépendent de $X$. On fait l'hypothèse que la fonction $gamma$ a une forme quelconque mais connue, qui dépend d'un paramètre $\ / Doctorat en sciences, Orientation statistique / info:eu-repo/semantics/nonPublished
