Ledningssystemområdet genomgår stora förändringar med anledning av Försvarsmaktens strategiska inriktning att skapa flexibla, tillgängliga och stående krigsförband. Inriktningen innebär en utmaning inom ledningssystemområdet då den medför ett tydligare krav än tidigare på att ledningsmateriel, teknik och personal är ständigt uppfyllda i samtliga krigsförband.Modulära enheter och förband som på ett flexibelt sätt skall kunna sättas samman till stridsgrupper skapar vid varje tillfälle ett behov av att designa operationen med dess ledningssystem. Ett ledningsstödsystem vars övergripande syfte är att stödja chefers utövande av ledning, det vill säga att tillgodose ledningsbehoven. Denna studie analyserar hur Försvarsmaktens strategiska inriktning påverkar ledningssystem- och ledningsstödsystemområdet, vid en insats med tillfälligt sammansatta förband på operativ och högre taktisk nivå.Syftet med studien är att analysera vilka faktorer som är centrala för effektiv ledning vid en gemensam operation.Studien menar att de centrala faktorerna vid ledning av en gemensam operation härrör sig till analys av: aktuell verksamhet och dess specifika behov, operationskonst och taktik, vald organisations behov och sammansättning. Analysen resulterar i specifika ledningsbehov och metodanpassningar.

Kundrelationerna i svenska B2C-företag är inte lika goda som de var för 60 år sedan och de är inte lika goda som företagen skulle önska att de var. Forskningsfrågan och syftet med uppsatsen var därför att förklara vad som påverkar svenska B2C-företags beslut att utnyttja Radio Frequency Identification (RFID) som identifieringsteknik för att personliggöra kundrelationer inom sina lojalitetsprogram. Studien utfördes som en fallstudie då vi undersökte hur två stora svenska B2C-företag, IKEA Family och ICA, arbetade med lojalitetsprogram, identifieringstekniker och hur de ställde sig till alternativa identifieringstekniker gestaltat genom RFID. Studien utfördes med deduktiv ansats genom inledande teoriinsamling och därefter genom intervjuer med en intervjuperson på vardera företag. De slutsatser som sedermera kunde dras var att tillräcklig kunskap saknas kring RFID och dess potential, att det är en ekonomisk fråga och en stor investering för företag som inte brukar vara först att ta till sig ny teknik som dessutom inte är standardiserad samt att det skulle kunna kränka kundernas integritet och därmed ha motsatt effekt till lojalitetsprogrammens syfte..

The goal of this thesis work is to enable an existing UHF radar to operate in the VHF band instead. In order to achieve this, new coherent local oscillators are required. Different options are suggested and one of them is implemented and analyzed..

The purpose of this thesis was to explore how Swedish librarians working with educational matters In Swedish: studiebibliotekarier experience his/her pedagogic work in the context of a public library. My intention was thus to reach an understanding of how they experienced their educational work. The following questions were asked: 1 How do the librarians experience the physical environment created for their students? 2 How do the librarians experience the co-operation with others involved in their work? 3 How do the librarians experience the formal task that he/she now is given? 4 How do the librarians experience their own pedagogic qualifications regarding the demands that are made upon them by the students? I have interviewed six librarians and incorporated theories on pedagogic roles in an educational context. I reached the conclusion that these librarians believed the environment to be important for the outcome of the students success with their studies.

Syftet med undersökningen är att granska patientkallelser till operationer för att se var kommunikationen eventuellt brister samt sammanställa en funktionell mall som ska kunna användas till de opererande verksamheterna inom Västmanlands sjukhus. Efter att ha fått ta del av autentiska kallelser och kallelsemallar granskas texternas innehåll, språk samt layout. Studien bygger på metodtriangulering genom dokumentanalys och analys av mötessamtal. Resultatet visar att kallelserna skiljer sig åt på flera olika plan. En del kallelser saknar nödvändig information som patienter behöver veta.

This thesis concerns to investigate renovations of existing buildings aiming at enabling energy efficiency, from a conservation and restoration perspective. This includes performing case studies of three projects in the Gothenburg area where renovations has been done and an analysis of directives raised by the EU and later implemented by the Swedish National Board of Housing, Building and Planning, Boverket. In addition to these, regulations enforced by the Swedish law, related to the topic, have been considered.The investigated projects in this case were the housing cooperative Välten in Brämaregården, the Solar Buildings in Järnbrott and Gårdsten as well as Katjas Gata 119 at Backa Röd. In order to measure and compare the results of these projects a comparison between the pre- and post-restoration energy consumption have been performed. To capture additional perspectives the grading system Operation Kungsörn has been applied.Regarding the comparison of energy consumption the renovation of Katjas Gata 119 was found preferable but showed in my view lacking attention to the cultural heritage of the area.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

Introduction: In this investigation I have illustrated, teacher treatment in a mono-cultural pre-school class and in a multicultural pre-school.Purpose: The purpose of the study was to illustrate how educators go about it when they face bilingual children to see how they work in a comparative perspective. The purpose was answered, based on four questions relating to how teachers relate to the meeting with bilingual children, the approach teachers use, which operation mode the use, if the take advantage of children's traditions, and if there is any different in the teachers? treatment of bilingual children in the mono-cultural pre-school class and in the multicultural pre-school.Theories: The theory is linked to the concepts like operation mode, inter-cultural approaches and communications.Methodology: The used methods are qualitative interviews with four pre-school, teachers where an interview guide with formulated questions and observations were used. The purpose of the working methods was to highlight teacher treatment of bilingual children to discover different approaches to meet the bilingual children.Conclusion: The study has shown that the multicultural pre-school working inter-culturally, they are taking advantage of children's home language that is lifted in the nursery and the children's background, while in the mono-cultural pre-school class, they meet bilingual children foremost to develop the Swedish language and they also show interest to the children's traditions. Teachers? treatment leads to a growing confidence in the children and knowledge for the cultural background..

The company now wants to investigate the possibility of changing their present softstarters to frequency inverters to supply power to their pump engines. They also want to investigate the possibility of future use in so called ?intelligent? houses.The purpose of this report is to investigate these possibilities..

This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.

The purpose of this study is to focus on library service for children in a hospital, which in turn is seen in relation to a traditional children s library. Four aspects of library work were investigated. These aspects were working methods, partners of co-operation for the libraries, media policy (acquisition, use of the collection and circulation procedures), as well as programme activities for children.The research method was qualitative and comparative in nature, consisting of case studies of two libraries : (1) the library in a children s hospital, known as Bokskogen at Astrid Lindgren s children s hospital in Stockholm and (2) a traditional children s library, the children s department at Eslövs city library. In each library interviews were conducted. The investigation shows that the librarians in the hospital library must be more outreaching and active in order to stimulate children to use library materials.

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Begreppet EBO har sedan 1991 gradvis växt fram som ett viktigt och centralt begrepp kopplat tillgenomförandet av operationer. Senaste exemplet är Operation Iraqi Freedom som började 2003 därförespråkarna anser att det fanns ett effektbaserat tankesätt från koalitionens sida i genomförandet. Detfinns dock många olika beskrivningar av vad begreppet egentligen innebär vilket gör att man kan diskuteraförekomsten av det effektbaserade tankesättet i en operation.Syftet med denna uppsats är att ge ett perspektiv på effektbaserade operationer samt att ge en fördjupadbeskrivning av uttrycket genom att ta fram kriterier som kan användas för att påvisa förekomsten avtankesättet i en specifik operation.Uppgiften besvaras genom att undersöka följande frågor.? Hur är det möjligt att förstå konceptet EBO i förhållande till begreppet Counter-insurgency?? Använder Koalitionen ett effektbaserat tankesätt när de genomför upprorsbekämpning i IRAKunder 2004?? Vilken effekt fick det effektbaserade tankesättet på operationerna?Resultatet av undersökningen visar att det förekommer effektbaserat tankesätt i de två COINoperationernai Haditha och Fallujah. Effekterna av båda operationerna är enligt amerikanska källorväldigt positiva vilket kan stämma i det korta perspektivet utifrån tilldelade uppgifter.

Velofarynxinsufficiens (VFI) inneba?r en nedsatt fo?rma?ga att under tal och fo?dointag sta?nga till mellan mun- och na?sha?la vilket leder till ett avvikande tal. Operation med svalglamba? a?r en metod som kan anva?ndas fo?r att behandla VFI och tidigare forskning har visat goda resultat avseende dess effekt pa? talet. Dock menar vissa forskare att operationen kan ha negativa effekter och att den bakomliggande orsaken till insufficiensen kan pa?verka graden av framga?ng.
