This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.

The Swedish traffic system is congested, especially in the urban areas; travellers face daily growing traffic jams and delays in public transport. In a congested traffic system, travellers need support to make smart and sustainable decisions and one such tool is traffic information.One issue today is that too few travellers use traffic information in support of their travel. Research shows that travellers would see great value in receiving the information; however current systems do not meet their requirements. This is a problem since the society would benefit greatly from a well functioning traffic information system.In this report, a number of channels that can be applicable for providing traffic information will be explored, with particular emphasis on interference information.The information channels are analyzed based upon the needs and requirements of the society and the traveller. The thesis of the report is: the more of these needs and requirements are met in a channel; the better is the channel to use for traffic information.

ABSTRACT This essay is about traffic analysis of Web servers. The purpose is to investigate if companies analyse the traffic on the Web server and if they use this information to create more than simple statistic reports. The questions that we will answer are the following: ? How common is traffic analysis on the Web server among companies? ? Is the Web administrator limited in analysing the Web traffic, if the company has the website on a Web hotel? ? Does the company uses the results they get from analysing the traffic on the Web server for updates and changes on the Web page? To answer these questions we made a questionnaire investigation by telephone interviewing the companies? webmasters. The extent of the investigation was 20 companies in Blekinge.

In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.

Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.

Several cities have implemented various projects to improve traffic safety in city centers.During 1970s and 1980s the city centers changed as the suburbs grew and large shopping centers were located outside the center. At the same time, several projects were initiated with construction of pedestrian streets and restriction of traffic in the center. In year 1994,shared-used areas were introduced in Sweden and these areas are often used in center environments.In Sweden, municipalities are responsible for integrating security in public places and in comprehensive plans and detailed development plans. The National Board of Housing,Building and Planning is the authority for administrating planning issues and develop general guidance about planning. Traffic is one of their key issues, although today there are no concrete guidelines from the National Board of Housing, Building and Planningfor the design of traffic safety in city centers.Traffic safety in city centers affects many people because the city center is a public place.It is therefore important that there are current guidelines available that are helpful for changes and improvements in traffic safety in the city center.The purpose of this report is to formulate guidelines for planning city centers from a traffic safety perspective.

Over the last 25 year IT development has greatly influenced the waycompanies are managed, the tremendous growth in the information society has made a huge amount of information extremely accessible. This has resulted in the problem of information overload where the large amount of information can affect the quality of a decision basis collected by a controller.The purpose of the study is to examine how a controller is affected by information overload and how this influences the decision basis. We intend to highlight the important elements to represent a high quality of information.A survey was conducted through a case study within a global affiliated company in the packaging industry. An adductive approach has been applied with a qualitative research method. Collected empirical material from interviews has been put into relation with existing theories.The case study indicates that there is no relationship between the problem of information overload and flawed decision basis.

Bakgrund: Controller är ett yrke som kom till Sverige på 1970-talet och det har sedan dess varit svårt att hitta en generell definition på vad en controllers huvudsakliga arbetsuppgifter är. Undersökningar med controllers har visat att yrket är i ständig utveckling. Litteratur inom området hävdar att en controller bör vara utbildad inom ekonomi och generellt sett arbeta med ekonomistyrning. Arbetsuppgifterna som controllers har varierar dock stort och problemet är att företag idag använder titeln controller som en fin titel och för att kunna forma rollen själva då den är så pass svårdefinierad.Syfte: Uppsatsens syfte är att definiera den typiska controllerns bakgrund samt dennes främsta arbetsuppgifter. Uppsatsen syftar även till att skapa förståelse för hur utvecklingen har sett ut inom yrket hittills samt skapa en bild av vilka arbetsområden controllers tror kommer kräva mer av deras tid i framtiden.Metod: För att uppfylla uppsatsens syfte har en kvantitativ studie gjorts där insamling av data har gjorts via en enkät.

The aim of this study is to examine which factors in a traffic wardens? situation at work that promote and which that inhibit satisfaction at work. The aim of this study is also to examine if there are any differences in the work experiences for traffic wardens that work alone versus those who work in a team of two. The following questions are examined in the study:?Which factors promote and which factors inhibit the work situation for traffic wardens??Are there any differences between traffic wardens that work alone and those who work with another colleague?The selection consisted of eight traffic wardens, of which four of them work with another colleague while the other four work by themselves.
