A study was made on four environmental ponds in Sölvesborgs municipality. The reason forthis was to see if the ponds had fulfilled some of the questions that was mentioned in theproject ?Rädda Hanöbukten?. The questions were as following; do the environmental pondsdecrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease theuse of groundwater in Sölvesborgs Municipality and are there any restrictions on what thewater in the ponds is allowed to be used for. In order to answer these questions aquestionnaire was made and interviews were held.

Företag behöver öka farten på införandet av mobila system för att kunna hänga med i den hårt ökande konkurrensen och globaliseringen som sker. För att satsa pengar i ny teknik är det dock viktigt att se tydliga affärsfördelar med investeringen. Här saknas kunskaper och medvetenhet hos företag om möjlig effektivisering som mobila system kan medföra i verksamheter. Syftet med undersökningen är att utvärdera Pågens mobila system utifrån ett organisatoriskt effektivitetsperspektiv. En fallstudie på Pågen AB har genomförts där effekterna av införandet av deras mobila orderhanteringssystem utvärderas.

Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development. The study is largely based on interviews with road contractors that perform work for Holmen Skog today.

The purpose of this study is to research into the role of the citizen and the educational system in Sweden throughout periods of time based on previous theoretic works, and also to deepen the understanding of students with special needs in Swedish education focusing on the primary school years. This shall be carried out by illustrating the different points of view and choices within the educational system that are at hand for students with concentration difficulties and social difficulties.I will analyze these points through a cultural and social perspective on contemporary society in order to contribute towards today?s discourse on the norm. The result of this empirical investigation presents a dilemma existing in the democratic educational system of today. Nationally and internationally, the educational system has been structured around a normative system containing both rights and duties that effect everyone working within it.

I den här rapporten undersöks Command Query Responsibility Segregation (CQRS),Event Sourcing och Task Based User Interface (händelsebaserat gränssnitt) somtillsammans bildar en annorlunda arkitektorisk uppbyggnad av system. Tanken bakomarkitekturen är att kunna spåra vad, när och hur data förändras i ett system samtmöjlighet att återskapa tidigare tillstånd, jämfört med traditionella system som endastlagrar, hanterar och presenterar data i dess nuvarande tillstånd. Undersökningen hargjorts genom att ta fram en bokningsprototyp och resulterade i för ?och nackdelar,användningsområde och hur CQRS, Event Sourcing och händelsebaserat gränssnitt kanimplementeras tillsammans..

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

This report is about planning a demolition. The purpose of this report is that it should become a base for a demolition of house J at the Academic hospital in Uppsala, and also to make general help for planning a demolition. This report also contains a part about how a change in the work environment affects general people. The work started with studies of literature and design of the general part of the report and then continued with a practical study of house J. From the experience of the first two parts of the report a general help for planning a demolition was shaped.

Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers. In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

This study explores whether environmental, social and governance (ESG) issues affect the monetary value of a company.The samples used in this study have been taken from the Johannesburg Stock Exchange (JSE) in South Africa. Since 2010, JSE have been categorizing companies using the King Code III criteria to establish a Socially Responsible Investment index (SRI index). Companies that fulfill the required number of criteria are classified as 'best performers' using the SRI index.  In this study the monetary value of a random sample of 'best performers' has been compared to the monetary value of a random sample of companies without an SRI index evaluation.This study found that companies without a SRI index have a higher unique risk, which means a lower stock price with a higher dividend yield. Companies with an SRI index evaluation have a lower unique risk, which means a higher stock price and lower dividend yield. In conclusion, this study shows that SRI adjusted companies have an enhanced monetary value in comparison to non- SRI adjusted companies..

Problemställning: Det existerar idag en betydande forskning som berör digitala system för kunskapsöverföring. Emellertid ser vi en tydlig brist i forskningen kring användandet av de olika systemen. Detta beror till stor del på problemet med att kunna mäta att en medarbetare verkligen använder systemet för kunskapsöverföring. Genom att studera kunskapsutbytet i organisationerna hade det varit möjligt att kartlägga de områden som påverkar användningen av digitala system för kunskapsöverföring. Frågeställning: Vilka faktorer påverkar användningen av digitala system för kunskapsöverföring? Syfte: Syftet är att skapa en modell som visar de faktorer som påverkar användningen av digitala system för kunskapsöverföring, samt att genomföra en första prövning av modellens giltighet genom en studie av tre företag.
