By conducting interviews, studies as well as scanning the current scientific landscape, this paper examines the opportunities of increasing current capacity within the public transportation system in Stockholm with simple financial means for the benefit of the travelers. The paper focuses on the central station of the subway system and how adjustments of processes carried out in relation to the turnstiles could increase performance within areas of interest, given the preferences of the travelers. The theoretical framework of the paper includes models from the field of capacity management as well as theories related to the pedestrian behavior. Applying these theories and models to the collected data, the paper derives some main conclusions. First of, people using the public transportations system, and especially the subway, consider speed and dependability as the most important performance objectives for the caretakers of the public transportation system, SL and MTR to master.

Umeå Energi are working towards a goal, that in the year of 2018, they will be completely climate neutral. As a part of this, one target is to reduce their grid losses by 4 % of the 2012 level, which corresponds to an overall reduction of the grid losses of just over 1.7 GWh. In many residential areas, the distribution grid is designed and rated for electric heating as the heating in the houses. As many of the houses later has been converted to other types of heating, their electricity use has decreased and the total power output from many of the secondary substations has decreased significantly. Because of this, many of these stations today are well oversized, which in turn means that the energy losses in these stations are unnecessarily high.In this degree project, 25 secondary substations have been studied, all located in residential areas in and around central Umeå.

Projektets utgångspunkt är ett nytt konstmuseum i Uppsala, i området bakom Uppsala centralstation, som nyligen genomgått ett ansiktslyft.Museets långsmala karaktär har hämtats från det intilliggande godsmagasinet och från tomtens form. Genom byggnaden har ett diagonalt stråk öppnats, för att ge möjlighet åt fotgängare att passera genom byggnaden och för att skapa liv och rörelse på platsen.Genom fönstren i passagen kan förbipasserande få en skymt av vad som händer inuti muséet. I passagen ligger museets entré, den pedagogiska verksamheten och ett kafé för allmänheten.Museets fasad är inspirerad av den arabiska mashrabiyan. Byggnaden har fönster längs hela fasaden, som i sin tur är täckta av skärmar tillverkade av sträckmetall. Ljuset tillåts komma in i byggnaden samtidigt som sträckmetallen täcker fasaden och bevarar något av museets hemligheter för förbipasserande.Museets inre väggar består av massiva betongskivor, placerade i ett rutnät som fått sin riktning av passagen genom huset.

Since the spring 2003 the tenant-owner home association the Terrace in Upplands Väsby municipality lies straight under the approach route to Arlanda Airport?s new third landing chute. Noise levels of over 70 dB have been measured in the area, which exceeds National Board of Housing?s, values for traffic noise at a terrace in connection to housing. By using the method of hedonisk pricing the essay tries to find out if there exists a willingness to pay to reduce the noise in the area.

Företaget Flextronics AB i Linköping testar moderna mobiltelefoner för tillverkares räkning. Som examensarbete har jag fått företagets uppdrag att utvärdera och förbättra deras testsystem DVT-UMTS (3G).DVT-UMTS är ett komplext system av komponenter, och man misstänker att dessa stör varandra inbördes, vilket i sin tur kan ge felaktiga mätresultat.Beträffande mottagarsidan hos en mobiltelefon tror man att DVT-UMTS p g a störningar, s k intermodulationsprodukter, uppvisar bitfelshalter i testet Rx Out of band blocking. Komponenter som kan tänkas ge störningar är continuous wave-generator och basstationssimulatorn. Antennanslutningen bortses från i undersökningen. Kontroll av CW-generatorn sker med hjälp av lågpassfilter, riktkopplare och dämpare.

In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is the second most popular game in Sweden and today the Swedish population consumes more wild boar meat than ever. As the wild boar population increases the wild boars are moving further north towards the contaminated areas, which creates an interest to study the state of 137Cs in wild boars in these areas. Muscle samples from wild boars collected during 2010-2013 were analyzed based on 137Cs content.

Gender equality and gender equality work is relevant for today's working life, and previously male-dominated occupations may be increasingly under pressure to become more equal. This paper aims to explore and understand how the firefighters at a station are experiencing gender and gender equality in rescue services.Using theories of how sex is done, how a power perspective and a structural approach can show men's and women's different conditions in an organization, and theories that are more specific to gender and change management the firefighters talk about gender and gender equality are analyzed. Essay results were collected through interviews with seven firefighters and then analyzed and interpreted with the help of theories.The analysis shows that there is a perception among the firefighters that men and women are biologically different and that required physical strength legitimizes the exclusion of women. Inequality is seen as something natural and by pursuing an active gender equality women are given unwarranted benefits. When physical strength becomes a legitimate reason for exclusion, the responsibility for gender inequality is put on women and that women don?t have what it takes.There is also a resistance against gender equality analyzed in the paper, and it's stated opposition seems to be directed against the management's way of recruiting women.

The retail sector is in a continuous development. What demand looks like and where the consumers want to shop has changed during the last years. Market place, demand, supply, external factors and politics affect how the retail sector develops. To make a market place attractive a variety of factors have to be considered.In Hong Kong a model called Rail & Property is used, this means that the development of the subway is integrated with the development of the city. The model is both successful and economically sustainable.Today the supply of shops and services in Stockholm´s subway stations is rather small.

Relationship between social behaviour, feeding behaviour and performance of boars using single-space feeders A study on the behavioural patterns of growing boars is presented. The study was preformed at Quality Genetics? boar testing station MÃ¥nseryd in Sweden. The boars were purebred Yorkshire, Hampshire or Landrace, born in nine different nucleus farms. The study is based on two batches of boars, with 63 and 69 boars respectively.

That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.

The use of combi-drilling during spring tillage has become very common in southern Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and seed coulters, which means that the draught requirement is relatively high. It thus requires large, heavy tractors, which compact the soil and are comparatively expensive to buy and run. A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish market.

Natura 2000 is part of the European Union: s framework to protect and preserve biological diversity. Natura 2000- areas are by the goverment appointed to areas of national interest for preserving nature. Also wind power stations are appointed as of national interest and the reason for this is the goverments goal to get energy from reneweble energysources. This essay describes when both these intrests conflict eachother when it comes to building wind power stations within Natura 2000- areas. The main focus of this essay is a casestudy of two cases from two different counties, Dalarna- and Norrbotten county, where applications have been made to build wind power stations within existing Natura 2000- ares, both cases have reached the court dealing with enviromental issues.

I have always lived around mines and around people work­ing with mines. They are a natural part of my life and, inev­itably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.

This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.
