Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

Northeast Stockholm is a region developing fast. There is already a great need for new transport solutions for the people commuting to the city, since long queues slow down car traffic and the local railway, Roslagsbanan, needs to be upgraded to attract more travelers. The competitive advantage of rail?traffic over the car when it comes to greenhouse gases and air pollutants is another reason to develop Roslagsbanan.This report investigates the differences between car and train to create a basis for a proposed expansion of Roslagsbanan. Once the proposal is presented, costs, emissions reductions and public benefits are analyzed.

This thesis takes its starting point in the humanistic cultural-geographical concept of place, with the aim of achieving a greater understanding of what constitutes the place Mon today. Mon is located in the northwestern part of Dalsland. Until 1879, the area was described as outlying land, but with the extension of the railway between V?nern and the Norwegian border, Mon's station community emerged. In the mid-20th century, all activities in Mon were phased out, and since then, the place has been inhabited by only about 10 year-round residents.

?Statistical Process Control? har för syfte att genom av statistiska metoder, mäta och analysera variation för att upptäcka särskilda orsaker till variation i processen och sedan genom eliminering av de orsakerna, förbättra processens kapabilitet.Inom SPC finns några begrepp som kräver lite förståelse, till exempel olika typer av variation, skapandet av styrdiagram och tolkning av detsamma för att hitta särskilda variationer. Till författarens kännedom finns idag inget spel som på ett enkelt och konkret sätt underlättar förståelse av dessa teorier.Inom område ?Lean Produktion? finns ett spel (?Lean-spelet?) som har för syfte att förklara begreppet slöseri, olika typer av slöseri i produktionsprocessen och hur man kan förbättra produktionen genom eliminering av de olika slöserierna inom produktionsprocessen. Syftet med detta examensarbete är att se på möjligheterna till ett liknande spel för SPC.Utgångspunkten för skapande av sådant spel var design av en monteringsprocess som färdiggör en produkt (i detta fall en traktor).

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

The theme of this thesis is citizen participation in the planning- and design process. It turns to everyone that studies landscape architecture or work as landscape architects and I hope that it can function as a ground for discussions as well as a source for inspiration. Rågsved is a suburb south of Stockholm. Just outside the centre of this suburb, a small industrial area called Snösätra, is located. In a few years time the leaseholds for the small industries will expire and the key question is: What will happen then? This is my general concern and it was the main cause for me to start this particular work. How do you attend to a place that appears like blank sheet of paper? To an empty page that can be filled with an infinite number of different formulations.

The aim of this study is to examine the perception of work of young men and women. A central problem that the study focus on is how young men and women value work, what do they expect to get out of work, and what are their experiences of work. The study also examines what work value and work mean for them. Eight young men and women between the ages of 22-25, currently working in different field, were interviewed. The individuals interviewed had different educational backgrounds.

This study investigates how productivity works when employees have remote work in their workplace. This study will also focus on challenges that cause productivity to decrease when remote work applies. The empirical data shows that individual productivity increases when employees work in a workplace that provides remote work. The data says that less distractions and high autonomy is a big factor to why employees feel that they work productively at home. Briefly it shows that a flexible workplace makes individual employees work productively and even motivates employees to work effectively because of increased concentration and undisturbed work environment.

Abstract:Because personal assistance is relatively new in social care in Sweden we were interested in to get more knowledge in how supervisors for personal assistants worked. In our study we choosed to look into how the supervisors worked with the physical work environment for the personal assistants. The questions we wanted to found answers for in this study was, which work directions the supervisors for personal assistants have around the physical work environment, which legal provisions there were around the physical work environment for the personal assistants and how the supervisors experienced the work with the physical work environment for the personal assistants. We did a qualitative interview study with supervisors for personal assistants. We realised in our study that there were big differences in how the supervisors for personal assistants worked with the physical work environment for the personal assistants.

FOU-stationen är en anläggning där man bedriver forskning och utveckling av LKAB'sprodukter. När den byggdes installerades även en dammutsugningsanläggning för att ta hand om damm som bildas vid krossning, siktning etc. Efter ett antal ombyggnationer och utbyten av utrustning fungerar nu denna dammutsugningsanläggning väldigt dåligt. Jag har gjort en utredning för att ta reda på varför det inte fungerar och vad man kan göra åt problemen..

Social work is a social phenomenon, existing in most societies, that has given rise to a multitude of special organizations and professions. For that reason social work is dealing with a complex identity. The purpose of this study is to illustrate how social workers and the scientific discourse interpret the concept of social work. In addition to that the study intends to show similarities and differencies. The research process containes two studies, one based on qualitative interviews with five social workers and the other consisting a surway of academic litterature.

The study examines the meaning of having a dog in the workplace of personnel who work with therapy. The purpose was to examine the personnel?s view of dogs in their work envi-ronment. The study uses two theories. One is ?psychosocial work environment? and the other theory used is ?symbolic interactionism?.

Mellan 1960 och 1970 lades många järnvägssträckor ner sin verksamhet i Sverige, spåren revs upp och bilen tog över vår vardags pendling på allvar. Nu när effekterna av bilens framfart blivit kända är tåget åter ett intressant alternativ och olika gamla tågsträckningar vill återupplivas. Simrishamnsbanan är en sådan tågsträcka och är tänkta att åter förena de orter som finns mellan Malmö och Simrishamn. Veberöd är en av de orter som ligger utmed den forna tågsträckan och orten ingår i Lundskommun och mitt syfte med detta examensarbete är att finna svar på hur Veberöd ur ett ekonomiskat, socialt och ekologiskt "hållbart" sätt ska kunna anpassa sig till ett stationsnära läge, med tyngdpunkt på: Bostadsstruktur, Infrastruktur och Grönstruktur. Detta utifrån ett scenario där Simrishamnsbanan realiseras. Examensarbetet börjar med att problematisera hållbarhetsbegreppet och begrepp som täthet och gleshet, därefter följer en omfattande analys av Veberöds historia, bostadsområden, grönstruktur, verksamhet och service.
