Kollektivtrafik längs Litteraturgatan. En jämförelse mellan olika kollektivtrafiksystem med avseende på kapacitet.
There are many elderly buildings, particularly those constructed during the million program, in need of renovations and plumbing replacement. An alternative to the traditional plumbing replacement is the relatively new and untested technique called relining. The purpose of the study is to thoroughly investigate the different types of relining that are currently available on the market to help enhance Peab?s knowledge before purchasing relining services. The theoretical part of this report is based on relevant information provided from companies, previous studies, investigations and reports within the area.
Hybriddrift i stridsfordon, fördelar och nackdelar
Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.
Utveckling av inbyggda system med grafisk programmering
The increase of complexity in embedded programming is forcing the development of higher level programminglanguages. These languages not only consist of traditional text based programming but also with graphical programminglanguages such as the programming language G from LabVIEW which is developed by National Instruments and havebeen around since the mid eighties. However since 2004 this language has also been able to program embeddedhardware, using the modules LabVIEW SDK and LabVIEW for ARM. This thesis shows how LabVIEW for ARM converts itsgraphical language G to C and then how C is flashed into the microprocessor. The thesis also takes up the pros and consof using G for embedded development.
With a few liters of clean drinking water : a Cost Benefit Analysis of the socio-economic effects from implementing new clean drinking water technologies in rural India
In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential.
The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.
Analys, modellering och återskapande av fordonsdynamiska rörelser i tåg
The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.
Trovärdighetsattribution : Skillnader i lögn- och sanningsbias beroende på syskonplacering, femfaktormodellen och misstänksamhet
The aim of this study was to investigate people?s ability to detect deception and if variables such as birth order, personality and suspiciousness affect this ability. The study was conducted at Växjö University with students as participants (n = 278). A film of two people arguing both for and against their own personal opinions was constructed and participants assessed credibility on a categorical scale (Honest/Dishonest). Neither birth order nor level of suspiciousness revealed significant differences as pertains to credibility attribution.
Skogsbränsleuttag vid förstagallring och dess påverkan på beståndsutveckling : simulering i Heureka med olika skötselprogram
Stands where pre commercial thinning has been ignored or inadequate often tend to have high stem density and low average diameter when they reach heights of thinning. In such stands, it can often be expensive to do a conventional pulpwood harvest as a first thinning. This study investigates the development of the stands and the economic outcome of forest fuel extraction, or a combined harvest as alternatives to the ordinary pulpwood harvest. Simulations in Heureka StandWise were performed for two thin and dense stands, which were constructed by data from the Swedish National Forest Inventory. The simulations show that the extraction of forest fuel in first thinning at an early stage can provide higher net revenue compared to conventional pulpwood harvest at the same time or later.
En knuten näve i silkeshandske - Kan statliga informationskampanjer stärka samhället och medborgaren?
Public opinion can be shaped as well as transformed in a number of ways. Government authorities occasionally make use of public information campaigns to educate and steer the public. In this thesis the balance between public and private, the individual and the society is analysed in terms of dimensions of individualism and communitarianism. These dissimilar theories on how the society ought to be constructed can be used when analysing many different policy areas, however, they also pinpoint the controversies seen in the public debate regarding Swedish information policy. Based on this analysis an empirical study identifies what kind of knowledge the state wants the citizens to possess and public information campaigns can be problematic.
Konstruktion av en autonom vindstation
Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.
En jämförelsestudie av koldioxidsläpp för en byggnad med trä- respektive betongstomme ur ett livscykelperspektiv
The goal with this examination thesis is to investigate the difference in carbon dioxide emissions between a building with a wooden versus concrete carcassing from a life cycle perspective. The huge amounts of carbon dioxide released into air from human activities must be reduced to prevent serious consequences. A way to limit this issue is through performing a comparative study where the result shows which of two products with the same function has the lowest emission of carbon dioxide, whereof the product with the lowest carbon dioxide pollution can be chosen.To be able to perform a study like this an object has been chosen and studies about life cycle analyses have been done. The rental square meter, the thermal conductivity value, the energy requirements and the placement of the building has been set equal in both framework types. There were solely dissimilarities of the two buildings taken into account when this comparison study was performed.The result of the study is that a building constructed with a wooden carcassing has the lowest amount of carbon dioxide emissions.
Är sexsäljare offer eller har de fattat ettmedvetet beslut? : En diskursanalys av svenska tidningsartiklar
This study is a critical discourse analysis of Swedish newspaper articles about prostitution. The purpose of the study is to investigate which discourse/discourses about prostitution that is/are adressed in the articles and identify the power relations and meanings that are constructed by the different subject posititions in the articles. Apart from critical discourse analysis social constructionism and a discussion about gender are applied in the analysis. The results supports findings in earlier research about prostitutionin Sweden; that the debate is focused around prostitution as sexual domination or prostitution regarded as a voluntary choice which rises demands of human rights for sexworkers. No prostitutes or buyers of sex where given the opportunity to comment on the matter, only journalists, politicians, social workers and policemen.
?Samlag /.../ det ar nar man hejjar pa? samma lag" : Skolkuratorers syn på sexualiteten hos unga med intellektuell funktionsnedsättning
Abstract: The aim of this study was to examine how the sexuality of young people with intellectual disability (ID) are constructed, based on how school counselors describe the situatuation of these youths and based on how the counselors describe their role in giving advice and discussing sex and relationships. The empirical data were collected through semi-structured interviewes with seven scool counselors and one consultant. The material was analyzed on the basis of theories about sexual script, stigma and social constructivism. The results showed that school counselors saw the young people with ID as a vulnerable group and as a group worthy of protection. Most of them had a picture of young girls as more vulnerable than young boys.
Barns röster i vårdnadsutredningar : Barn som talar eller omtalade barn?

Frihetens bakgård en litteratursociologisk studie om självets identitetsvåndor i det senmoderna samhället
This Masters thesis is analysing four Swedish novels written by first time authors published between 1993-2002. The purpose is to make the fictitious main characters illustrate what conditions and obstacles there can be for the individual of today to create a self-identity. Anthony Giddens ideas about the self in the late modern society are used as a theoretical framework. In the core of Giddens theory is the concept of reflexitivity which means that the self must be constructed in a continuous fashion because the overall conditions in society are subject to constant change. The questions posed in this study are dependable on Giddens in general and the concept of reflexivity in particular.
