Rykte & dåliga betyg : Fallet: Jordbromalmsskolan
Three different factors are thought to be involved in the increased segregation in Stockholm: the living segregation, scientific and political dissonances and the social economical factor. Many segregated areas have many inhabitants with foreign background. Schools in these areas have a higher number of students with lower grades compared to other schools with higher number of students that are ethnical Swedes. Jordbromalmsskolan is a school in Haninge kommun that is one of the seven schools in Stockholms suburbs where students graduate with the lowest grades. The school is suffering from a very bad reputation because of many problems like fights between students and lack of resources like purchase stop.
Optimering av multiprocessorsystem med hjälp av schemaläggning
A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.
På vilka grunder väljer föräldrar skola?
The study is made in Nacka, a suburb of the capital of Sweden, Stockholm, and focuses on ?the parental school choice" that takes place when children start in first grade at the age of six. New differences in the number of pupils attending various municipal schools have appeared after reforms in the early 1990s giving parents free choice of elementary school for their children. Some schools are located in areas where most children have a middle class background, while others are placed in less attractive surroundings where the parents have a lower educational status, and are more often immigrants. Parents living in the latter kind of surroundings can now send their children to schools further off, but located in more attractive areas. This leads to some schools get an increasing number of pupils and others gets a decreasing.
Analys av hur byggnadens höjd påverkar energiförbrukningen i flerbostads- och kontorshus
This diploma work has been carried out in collaboration with the building contractor Sh Bygg Fastighetsutveckling AB in Uppsala with the intention to investigate how the height of a building affects various energy aspects such as transmission losses, infiltration, and the specific energy usage. Three different reference objects have been studied. The reference objects have been simulated for four different heights in the calculation program VIP-Energy.The results show that an increase in floor number can lead to both advantages and disadvantages. As the number of floors increases, transmission losses per square meter floor area decreases. However, as the height of the building increases, the reduction rate decreases.
Ett nytt stadsbibliotek i Stockholm: En diskursanalys bakom visionen för ett nytt folkbibliotek
The purpose of this Master?s thesis is to examine and analyze the discourse concerning a new public library in Stockholm. The paper further discusses how this discourse corresponds with what is written about public libraries in a number of national and international documents. To do this I have utilized the discourse theory of Laclau and Mouffe. By using some of their instruments I have established the discourse around a number of keywords.
Resource planning for internal logistics : A tool designed for the material handling department at Scania Axles and Gearboxes
This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.
Framtidsoptimerad livscykeloch hantering av versioner : för Scanias Fleet Managementavdelning
In the haulage business customers are constantly requesting new features. Hence thedevelopment department must constantly update their system which ultimatelyresults in a variety of versions of the system. The large number of versions creates acomplexity which often reduces product quality and extends the developmentlifecycle time.The work on the following thesis has taken place at Scania?s Fleet Managementdepartment, which develops tools for hauliers to track their vehicle fleet in real time.The purpose of this thesis was to examine how Scania can handle an increasedamount of versions of the Fleet Management System which Scania expect will be seenin the future. The investigation was conducted by preparing a number of differentscenarios that formed the basis for a discussion of what these different scenarioswould mean for different parts of Scania?s business.
Utvärdering av flygbildstolkning för uppskattning av beståndsvariabler och åtgärdsförslag i ungskogar : en studie på Korsnäs Skog och Bergvik Skog AB i västra Dalarna
In Korsnäs district Dala Väst there were problems with information concerning their younger forests, mainly those in pre-thinning stage. They were divided into large, heterogeneous stands with often poor stand data quality. In 2006 an aerial photo interpretation of the young forests was conducted to fix these problems. Necessary information to get from the interpretation were silvicultural management suggestions, new stand delineation and new stand data. This thesis is supposed to evaluate the quality and usability of the interpreted data.
To evaluate the interpretation an objective control inventory was conducted in 60 stands, either through callipering or counting stems.
Stridsyxor eller båtyxor : En diskussion om symboliken och dess betydelse
My intention with this paper is to try to understand the meaning of the double sex symbols which can be identified on a number of Neolithic so called battle axes from the region round the lake Mälaren in Sweden. My conclusions are drawn after having studied a number of archaeological thesises. I have realized that the society was egalitarian from what is said about the funeral habits since women and men were buried with the same care. Ceramics from the Skogsmossen site show a very long continuity over 15-20 generations. These facts indicate a peaceful society without traumatic breaks where knowledge would have been lost.
Effektivisering av UI-utveckling i datorspel
This thesis presents my work at the company Fatshark AB in Stockholm. My supervisor Rikard Blomberg, who works as a chief technology officer at Fatshark and is one of the owners of the company, explained that they had experienced weaknesses in the methodology used when developing heads up displays (HUD) for their games. In the latest production, Lead and Gold, the HUD had been redesigned a number of times, becoming an unnecessarily big expense due to the number of work hours invested. In modern software development, an iterative workflow is commonly encouraged. Despite this fact, the work efficiency could likely be increased by setting up guidelines as a help in the process of developing HUDs and reviewing the solutions.
Variation in piglet mortality between and within satellites in a sow pool
The piglet mortality rates have become a major issue in today?s pig production. While other production traits such as number of born piglets or produced piglets per sow have been improved, the mortality rate has escalated. High mortality rates before weaning does not only affect the economy but must also be looked at as both an animal welfare problem and an ethical issue. The background to this problem has been addressed many times, and its salvation has also been addressed by breeding.
"Dom är ju också människor. Precis som du och jag." : En kvalitativ studie om socialsekreterares syn på långvarigt narkotikamissbruk
The aim of this study is to investigate a number of social worker views on long -term drug abuse and how they feel that this group of individuals should be treated. Our purpose is also to examine these social worker discretion in terms of decision-making under the Socialtjänstlagen (SoL) and Lag om missbrukare i vissa fall (LVM ).We conducted two focus group interviews and assumed a number of open questions. Our empirical data have been categorized by the study's purpose and issues and by recurring themes in our individual stories.Our results shows that all social workers believe that one should always look at the big picture in estimates related to drug users. They also believe that the process of long -term addicts occasionally feels hopeless. Social workers felt that their room for maneuver in terms of decision-making was fairly limited.
Simulering av miljoner grindar med Count Algoritmen
A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

Naturhänsyn vid föryngringsavverkningar : En jämförelse mellan certifierade och o-certifierade hyggen
A growing number of Swedish forest owners are choosing to certify their forestry. However, there appears to be a lack of field surveys which describe differences between certified and non-certified forests concerning the degree of completed environmental considerations. In order to know to what extent certified forests contribute towards improved environmental consideration, we need studies on how large the difference is in relation to non-certified forests.Differences between certified and non-certified forest clearings were quantified through an inventory of the number of retention trees, dead trees and snags. The result showed that the retained number of the investigated parameters varied greatly between individual clearings, regardless of certification status. However, the results suggested that the certified clearings had an average higher incidence ofthe investigated parameters.
