The authors had access to a temporary lab at Zenit and electron microscope at Halmstad University where material tests were performed. The authors have also had access to measurement equipment to measure amounts of ozone.During the work, the authors have mapped how an existing ozone generator works and then have their own development.

??Auktorisation och ackreditering inom Försvarsmakten : En studie i nyttan av en standardiserad process för att hantera informationssäkerhet

???Information Technology is an essential part of the society today, not least in large ???organisations dealing with sensitive information. An example of such an organisation is the Swedish Armed Forces which indeed is in the need of ways to ensure information security in their Information Technology systems. The means which is used is an authorisation and accreditation process.All Information Technology systems go through a life cycle which includes realisation, usage, development and liquidation. In the Swedish Armed Forces the lifecycle is an authorisation process.

Det är lite gambling, man kan aldrig veta hur det blir i slutändan : Socialsekreterares erfarenhet av bedömning av en viss insats för barn och ungdomar

Social workers in this study describes various experiences of the assessments of interventions for children and adolescents. Social workers experience of the many different situations where an assessment of best effort must be made on the basis of BBIC, which is the Social Services investigation records. To make this assessment, the Social workers need social assistance and support of their colleagues and manager. Knowledge mixed with experience is also an important part when it comes to being professional and not let emotions control that could otherwise be happened when the social worker meets and builds relationships with clients. Social workers are also those who will decide which achievement the client needs from the needs.

Miljöbyggnad, GULD värt? : En undersökning av fastighetsägares erfarenheter och tankar kring ett nytt certifieringssystem

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

Kapitalbudgetering och ekonomisk styrning : En fallstudie av svenska skogsindustrin

Bakgrund: Investeringsbeslut är ett av de viktigaste besluten som tas av chefer i företag. Besluten grundar sig på investeringskalkyler, som ryms inom begreppet kapitalbudgetering. I företagsekonomisk litteratur beskrivs sällan samband mellan kapitalbudgetering och annan ekonomisk styrning, vilket innebär att det finns ett tomrum inom forskningsområdet. Syfte: Syftet med uppsatsen är att beskriva hur företag inom den svenska skogsindustrin utformar och använder kapitalbudgetar som beslutsunderlag samt utreda och förklara sambandet mellan kapitalbudgetering och annan ekonomisk styrning. Metod: I studien har kvalitativ metod och fallstudier använts.

Uthållig sanitet : en förstudie i staden Picota, Peru

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.

Lärares syn på hur den fysiska klassrumsmiljön påverkar elevernas lärande

My main purpose for this paper was to find out what the four teachers I interviewed thought about the design of their classroom and how they linked that to pedagogy, pupils learning and policy documents. I also wanted to find out if classroom design were something they discuss and reflects on in the college.My questions for this study were: What do some teachers who work in the early ages in the school think about the classroom design? Do these teachers link the classroom design to policy documents or pedagogy? Do these teachers consider classroom design to be something that should be discussed in the same way as other factors (for example teaching aids, resources etc.) within the college?My method was to make qualitative interviews with four teachers, analyze their answers and link them to my main theories and research in the area of the study. My main theories were multimodal communication, which means that there are several systems of signs in communication, which all have an essential function for the meaning of the communicated. It also means that learning happens both individually and socially and that school is a social construction, and that the system of opportunities and boundaries in which it takes form is mediated within our multimodal systems.

Skyltsystem till källsorteringsmodul

Målsättningen för projektet var att ta fram en miljövänlig, innovativ lösning på ett skyltsystem för källsorteringsstationer i kontorsmiljö åt Eko Systems AB. Skyltlösningen som idag används på producenten Eko Systems sorteringsmoduler fungerar väl hos användarna men både inköpare och producent ser brister i bl.a. lagerhållning, miljöanpassning, användarvänlighet och kundanpassning, samt i hanteringen av den mängd olika skyltar som producenten måste tillhandahålla. Arbetet resulterade i att ett nytt helhetskoncept för en skylt med utbytbar information togs fram. Konceptet uppfyller producentens höga krav på att vara miljövänlig och nytänkande, med en attraktiv design anpassad till företagets nuvarande produkter.

Kravspecifikationens innehåll och struktur : en jämförelse med byggbranschens kontraktshandlingar

Dynamiken i det moderna samhället gör att förutsättningarna för företag och organisationer ständigt förändras. Informationssystemen blir då väldigt viktiga för att företagen skall få rätt information i rätt tid. Även informationssystemen måste ibland förändras och kraven på ett nytt informationssystem anges i en kravspecifikation. Denna kravspecifikation upprättas i den del av systemutvecklingsarbetet som kallas för requirements engineering (RE).Denna rapport är ett examensarbete inom det systemvetenskapliga programmet vid Högskolan i Skövde. Författaren har tidigare arbetat som byggnadsingenjör i flera år och gör i detta arbete en jämförelse mellan byggbranschens kontraktshandlingar och systemutvecklingsområdets kravspecifikation.

Hälsoeffekter från trafikbuller vid Bäckegatan

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Konceptframtagning för flakväxlarkärra

Arbetet bygger på att de informationssystem som används idag men som blir allt äldre och därigenom inte klarar de krav som ställs på dem. Detta medför att informationssystemen måste migreras till modernare plattformar, då företagen dels inte klarar sig utan dess nuvarande funktionalitet och dels måste vidareutveckla systemen.Detta arbete tar upp olika sätt som detta kan genomföras på och vilka problem som kan komma att uppstå när detta sker. För att kunna undersöka detta så genomfördes ett antal migrationer. Språken som migrationen kommer att ske mellan är Visual Basic 6 och Visual Basic .net. Migrationerna kommer att ske med hjälp av ett migrationsverktyg, samt ett ramverk som i arbetet skräddarsys för just arbetets typ av migrationer.Det arbetet kommer fram till är att det sker problem vid användande av ett verktyg och även att det inte ger tillräckligt med respons på vad som gått snett under migrationerna..

Mysak Konstruktion av ett mät- och stimulikort för mobiltelefoner

Vid högvolymsproduktion av konsumentelektronik är testtid, mätnogrannhet och fabriksgolvsutrymme synonymt med kostnader. Detta har gjort att man på sektionen Test Engineering vid Ericsson Mobile Communications fabrik i Linköping tagit fram ett testkoncept, kallat Pelle-konceptet, där datorkraft och mätutrustning flyttas in i små utrymmessnåla testfixturer anpassade för både robotiserade produktionslinor och manuella. Det nya testkonceptet saknade på våren 1998 ett generellt mät- och stimulikort för mobiltelefoner vilket specificerades och konstruerades  under sommren och hösten 1998 av författaren och Stefan Lantz. I rapporten beskrivs arbetet med att specificera kortets funktionsblock samt detaljkonstruktion av de funktionsblock som författaren ansvarat för. Rapporten ger även en inblick i designarbetet och dess svårigheter för ett mät- och stimulikort med många olika funktionsblock på en mycket begränsad yta, samt de problem som uppstår i många projekt till följd av förändrade krav, missupfattningar, kommunikationsmissar och saknad dokumentation..
