This master thesis is developed based on the desire of the water and sewage department in the municipality of Karlskrona. The department, which vouches for the quality of produced drinking water and sewage cleaning, was in need of help dealing with risk analysis.The water and sewage department is obliged to identify and assess risks according to Swedish legislation. However, no guides for this purpose regarding safety, health, environment and quality were available. The aim of this report was to accomplish a guideline for the performance of risk analysis within water and sewage plants. If the guideline is used, the requirements in the legislation will be obtained.

Varje dag begås misstag utav människor. För piloter kan dessa misstag bli fatala. Länge har man vid flygolyckor endast sett till de direkta misstag som blivit begångna och på så sätt skaffat sig en syndabock. I detta arbete kan dock vikten av att uppmärksamma faktorer som varit bakomliggande i organisationen påvisas. Då en olycka inträffar skiljer man mellan osäkra handlingar och latenta förhållanden.

In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.

Byggsektorn har fortfarande svårigheter med att hantera fuktproblematiken.  Vi har valt att fokusera på hanteringen av material i produktion. Den informationssamling vi utfört ligger till grund för vår analys och slutsats. Vi har intervjuat flera olika entreprenörer från byggbranschen för att ge oss en helhetssyn av fuktsäkerheten ute på byggarbetsplatserna. Studien påvisar att det råder brister både på beställar- och entreprenörssidan. Vi ser att det finns potential för förbättring när det så krävs.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

Det är väl känt att sjuksköterskor ofta har en hög nivå av arbetsrelaterad stress. Syftet meddenna studie var att hitta orsaker till stress hos sjuksköterskor och hur detta påverkaromvårdnaden av patienter. Studien genomfördes som en litteraturstudie vilken omfattade 12artiklar med varierande metoder och upplägg utförda i Europa och Nordamerika. Orsaker tillstress identifierades och tematiserades i två teman; Hur påverkas patienten ochomvårdnaden samt Hur påverkas sjuksköterskan. Följande huvudsakliga resultat hittades:Hög bemanningsnivå visade samband med hög omvårdnadskvalitet, hög arbetstillfredsställelseoch låg stress.

When forces in foundation piles are calculated according to classic theory, thefoundation are assumed to be infinitely rigid which means that the foundation will notbend. High buildings need their whole width to be stable and use the ground floorwall as a foundation. But when, for example windows are needed in the ground floorwall, the stiffness of the foundation decreases which change the forces in the piles. Inthis report the difference of pile forces versus classic theory has been analyzed, and ifpile forces can be calculated as in classic theory. Further on, the effects of the wallmovement were analysed and how the buildings crack safety would be affected by themovement at the ground floor.

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

I och med lanseringen av nya och mobila plattformar, såsom smarttelefoner och surfplattor, uppstår svårigheter med att anpassa webbsidor för samtliga typer av enheter. Tidigare har mobila applikationer (appar) och mobila sidor använts för att överkomma dessa problem. Responsive Web Design (RWD) är en ung designprincip som uppkom 2010 och har anammats av många webbutvecklare. Designprincipen medför att en webbsidas presentation förändras beroende på skärmstorleken som används för att visa sidan. I en studie har fem företag intervjuats för att få deras tankar och åsikter om RWD i jämförelse med utveckling av mobila sidor och appar.

The purpose of the study is to investigate and elucidate how low-cost airlines can influence and develop tourism in a region. In order to bring about the purpose the author used two research questions. Have low-cost airlines contributed to regional development? How many additional visitors have low-cost airlines contributed to Stockholm? In order to answer these questions a survey was carried out at Arlanda airport and statistics were collected. The results of the study show that there has been a regional development.

The purpose of this literature study was to describe techniques for monitoring general anesthesia and standing chemical restraint in the horse. A number of various techniques and devices related to e.g. blood pressure measurement, blood gas analysis and pulse oximetry are defined, and finally their clinical relevance and reliability are discussed. The equine patient is generally far more exposed to anesthesia-related risks than other smaller species. Complications such as hypotension and hypercapnia are commonly seen during general anesthesia. Thus, close monitoring is essentially performed by the veterinary nurse, whom is responsible for monitoring the anesthetized patient.

Today we live in a world where the demands increase in the aeronautics industry. This creates a situation where no mistakes are allowed about the regulations and for those who are supposed to follow these. Safety comes first, tracking of components, Service Bulletins which are recommendations from the manufactures and Airworthiness Directives which are demands from the authorities, these need to be updated at all time and everything that is done on a aircraft need to be documented.This creates a situation where today maintenance shops need to have full control of all parts of the organization, which creates a need for a working data system.The goal with this exam work is to evaluate the best way to implicate the new bought data system called "System Aircraft Management" on the basis of the needs of Täby Air Maintenance AB. The system are supposed to get started technically and also be implicated to the users of the system. This work will be focused to create a effective working plan to get SAM implicated with no interruption in the daily work.

This paper constitutes graduate work at the Depart-ment of Urban and Rural Development at the Swedish University of Agricultural Sciences. In this paper the urban structure of the million program suburb Husby in Stockholm is examined and what effect this structure has on social life in the area. The main objective of the study has been to, with the help of morphological analyses, examine how to create meeting places and make the Husby Park more accessiblefor the inhabitants in Husby. There has been a selection of analyses to ensure that Husby?s spatial relationship with surrounding suburbs as well as local spaces in the Husby Park is described.

Diet is mentioned by many seamen as a subject of joy and aims to give nutritional value and sufficient energy to manage a long working day at sea. The purpose with this investigation is to examine if there is a need among seamen to receive more information about diet regulations onboard and if they wish that it was shaped differently to meet their demands. The study is based on a literature part where diet regulations are examined and an interview part with semi structured qualitative interviews with five seamen. The conclusion of the study indicates that seamen have limited knowledge about the enunciation of the regulation, where it is to be found and consider it to be imprecise. Interviews showed that seamen believe that variety is the most important factor in diet intake and it was this expression that they primarily wanted stated in the regulations.

Hypothermia during anaesthesia is a well-known phenomenon that may cause several side-effects such as greater risk of postoperative wound infection and increased risk of heart complications. The most efficient way to avoid this is to prevent hypothermia from occurring. The aim of this paper was to compile the research on the most efficient way to prevent hypothermia during anaesthesia for cats and dogs, and to compare these results to how Swedish animal hospitals prevent hypothermia today. To investigate this, a survey was sent out to several animal hospitals around Sweden to see what methods they used to prevent hypothermia in their clinics. It is difficult if not impossible to prevent the body temperature from falling slightly when anaesthesia is induced because of the drug interactions in the body that follow from the drugs given. A 1-1,5°C decrease in body temperature is to be expected and is difficult to avoid.
