Den klassiska approachen till navigering innefattar att agenten håller en intern representativ modell av omgivningen. Denna approach har emellertid många nackdelar, speciellt för dynamiska miljöer. En modernare approach är att förlita sig på den faktiska omgivningen istället för en modell av denna. Detta arbete presenterar en undersökning av navigeringsproblemet och hur väl det löses av agenter vars kontrollmekanismer utgörs artificiella neurala nätverk. Tillförlitligheten hos de två neurala arkitekturerna Extended sequential cascaded network och Self-organized recurrent network bestäms genom experiment.

Social networks have increased significantly during the latest decades, but what does the cooperation include and how does the network processes look like? Networks are not specific for communities in the 2000?s or for that matter human organisations, but the ability to build networks and introduce more actors to the organisation have become easier with today?s communication technology. The study is about the Norrköping Municipality membership in the transnational network Sweden Emilia Romagna Network (SERN). It gives an insight into how networking and cooperation can be seen by politicians and officials, based on mission statements and the reason why a municipality choose to participate in transnational networks. The study aims to examine how Norrköping Municipality uses the SERN network and what the network have resulted in since the beginning of the municipality membership in 2005. It is a qualitative study which involves interviews with officials and politicians from the Municipality of Norrköping and textual material from SERN?s strategy documents and policies.

The purpose of the paper is to explore of what importance network relations are to the small fashion company Clemens en August. Clemens en August is a new German fashion label, which has the goal to become established in the high-end segment. The company uses an innovative sales strategy, directly distributing its products to the end costumer. The theories used will serve as a tool to analyze Clemens en August 's strategy from a network perspective. As the Bachelors thesis nr: 12464 ?Clemens en August ? A Network Perspective?, authors; Malin Elmlid, Biancastella De Angelis and Carsten Juldorf, date of approval 2006-01-11, contains delicate data about the studied company we have decided to classify it as secret.

The interest in companies that are based outside the cities has grown, and many of these companies have focused their activities around service. The countryside companies meet some difficulties in marketing and communication with other entrepreneurs. A network with service based companies in the countryside could help the individual companies to promote themselves and also give inspiration and new ideas to develop their business. The aim of this study is to investigate how a countryside network can be organized but also what conditions is needed to make the network function. The theory is based on a literature study of the three major topics "countryside", "networking" and "marketing".

This paper investigates, through an actor-network theory perspective, how the recreation area Lo?vsta-Kyrkhamn-Riddersvik northwest of Stockholm has developed from being a dumping site into becoming a nature reserve. This investigation also tries to describe and explain which values that have been promoted in the area by the local voluntary associations and companies. Lo?vsta-Kyrkhamn-Riddersvik has been inhabited for more than 3000 years, originally with farming as the most important business.

The work describes the development of an adjustment algorithm that will replace today?s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system.Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two.The report describe the development of the algorithms and how they behave during simulations and tests on real robots.

I det här arbetet har algoritmen Simulated Annealing undersökts med avseende på dess möjlig att användas för att minimera av kostnaden för ett singelfrekvensnät för digital tv. Undersökningen är gjord genom att simulera ett antal testfall för att utreda hur olika ingående optimeringsparametrar inverkar på slutresultatet. Alla försök har genomförts i ett egenkonstruerat simuleringsverktyg, gjort i Matlab. En jämförelse av resultaten för två olika sätt att hantera täckningskraven har också gjorts, Simulated Annealing med- respektive utan straff metod. Alla genomförda försök har genererat en betydande kostnadssänkning jämfört med startkonfigurationen.

No infrastructures today are growing faster then communication network. The requirement of being able to communicate in a fast and qualified environment to a low cost increases in line with the development and competition. Itera Networks is no exception when it comes to rapidly developing new and better network solutions for themselves and for their customers. With these requirements in mind their needs for an analysis of the existing communication solution becomes very obvious. This project contains such an analysis in which various studies of the existing network environment have been made.

This paper describes a case study of the largest film production ever conducted in Scandinavia. The study aims at explaining the complex relationships in the network structure in which the project took place. Coordination of creative projects carried out in a network context, includes handling conflicting interest and contradictions. Creativity needs space and freedom while projects need structure and coordination, whereby controlling these projects becomes complex. Adding to the complexity, does the loose form of organization that the network structure represents, without any long term structure.

 The aim of this study was to examine how young people, who have been treated for their misuse and/or to learn to handle a parent's misuse, portrayed the network's implication in their wishes about improving their lives, to make new choices. The network included members of nuclear family, relatives, important persons at school/work and friends. The ?professional network? (therapists and social workers) also became a part in the young people's life during a period. The main issues of this study concerned differences in their experiences of the young persons´ network relationships in before, during and after completed treatment.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

This thesis aspires to construct a routing optimization method customized for Volvo Powerstrain?s manufacturing plant in Skövde, Sweden. In order to enforce Volvo?s own understanding and control of there own organization, as well as optimize the utilization of the in-house tow trains, the BRO methodology where created. The methodology where created from observations of the currents working environment, analysis of order data as well as a comparison with two similar producing factories.

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..
