Utvärdering av Capcals förmåga att beräkna framkomlighet

Performance of an intersection affects the total travel time in a traffic network. An intersection with good performance can easily be described by its contribution to lower travel time than in a comparable intersection. The travel time is of importance in the cost calculations when a specific intersection is to be chosen and designed. It is important to be able to make correct and precise performance calculations so that the cost calculations will not be incorrect. For that purpose the software Capcal, which is a traffic model for intersection analysis on performance, is used in Sweden.

Framtagande av kravspecifikation för standardsystem

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

Optimeringsflöde av modelleringsprogram vid broprojektering : Analys av de tre modelleringsprogrammen Tekla Structures, Revit 2013 och Rhinoceros

This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

En Modell av SOA för Agila Organisationer

In a dynamic and unpredictable reality, either rigid structures or silo architectures areappropriate ways to organize an agile organization. This thesis enlightens these relationsbetween Service Oriented Architecture (SOA) and an organization who acts in a varied andconstantly changing business environment. In other words, this thesis enlightens the question:?How suitable is SOA to organize the enterprise who will meet a constantly changing andheterogenic business environment?.The thesis presents a model where an efficient organization must be agile to be able to actquickly in the business environments with constantly changing desires, needs, expectations,desires etc. According to the same model a Service Oriented Architecture organizes theenterprise elements such as processes, resources, competences, responsibilities, informationsystems etc.

Information Audit en informationsgranskning vid Borås Stads äldre- och handikappomsorg inom kommundel Centrum.

An information audit identifies, among other things, organizations information resources, the information flow and the needs of the information users. The purpose of this masters thesis was to describe the management of information within a local unit of Borås municipality by putting an information audit-method in practice. The focus was on three issues: What information needs could be seen in the organization? How does the information flow through the organization? How does Sugan Henczels seven-stage model serve as a tool to map the management of information within the local unit? The study only described the situation at a certain time at the chosen organization. The seven-stage information audit model was revised and adjusted to the studied organization by only carrying out four of the seven steps: Planning, Data collection, Data analysis and Data evaluation.

Att skapa en motkultur : En religionspsykologisk undersökning av Livets Ord som religiös minoritet i en sekulär kulturell kontext

In this textual analysis I have examined the book Att följa Jesus by Ulf Ekman and information from Word of Life's official website. The aim of this study is to see how a religious leader is shaping the identity of the groups members after a certain pattern that differs from the surrounding, secular society. The research focus  of this essay includes several aspects:  how a culture is formed in a religious minority in contrast to the prevailing cultural context; how the material can be explained by Paul Pruyser?s theory on the psychological worlds; how what Ulf Ekman writes about distinguishing themselves from the environment differs from how other religious minority groups distinguish their identity;  and,  how the psychological world, expected behavior, and context of Word of Life can be structured by Valerie DeMarinis? model of assessment. I have placed Word of Life in a realistic illusionistic world developed from Paul Pruyser?s theory of psychological worlds.

Förbättring av mjukvarubibliotek för parallellberäkningar med programmeringsmodellen Chunks and Tasks

Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.

Modellbygge av mekaniksystem och riktmotorer i stridsvagn 122

This master thesis is one part of a project, called ?StabSim?, with the purpose to develop a simulation model for the align and stabilisation system in main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system. The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these.

Chromatin functions : the DNA repair connection

The aim of this master thesis was to examine a possible connection between chromatin functions and the DNA damage repair system, with the imprinted IGF2/H19 locus as a bait. Interactions can occur within and between chromosomes and it has been shown that H19 ICR on both alleles can communicate with alleles on other chromosomes. The methylation-sensitive insulator protein CTCF is bound on the maternal H19 ICR and acts as an insulator by blocking the IGF2 promoter to access its enhancers. This is possible by formation of loop structures by CTCF that enables intra and inter-chromosomal interactions. CTCF is poly(ADP-ribosyl)ated by PARP-1 when it is bound to H19 ICR.

CAP KC3-12 : Design and finite element analysis

In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.

Integration och intersektionalitet - Tre skånska kommuners användning av intersektionalitetsperspektivet

Integration is a phenomena that occurs in all societies that experience any form of immigration. This process is dependent on how we analyze, both the groups of immigrants, and how we analyze the society in which they becoming integrated.Intersectionality is one method of analyzing this framework. By applying the categories: gender, class and race on the integration process, we get a more complex picture of the subject. Therefore we also become more able to adjust the actions and arrangement around the different questions of inte-gration.In this essay I try to explain what the intersectionality is, how it is used and how it can apply in integration as a specific subject. I also apply the intersectionality model on different policy documents from Malmö, Vellinge and Landskrona to find out if they show any awareness of this model both explicitly and implicitly..

Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

BIM Building Information Model : Hinder & Drivkraft

The  construction  industry  is  a  costly  business  such  in  respect  of  capital  for  most construction defects which then require rework, tear down and rebuild again. This study is  meaningful  awareness  of  tools  that  can  reduce  this  best  through  communication  and information sharing between the parties.  The  construction  industry  is  known  as  temporary  projects  organizations,  where  the construction  project  consists  of  several  actors  who  have  to  communicate  and  share information  between  them  to  avoid  mistakes  later  in  the  build  time.  These  actors  are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to  create  a  routine  for  the  association  and  the  shattering  of  these  actors.  To  implement such  behavior  using  a  tool  such  as  BIM  in  the  industry  whose  size  perhaps  is indescribable may be a very hard task.  BIM (Building Information Model) could be seen as the solution to this problem because it  acts  as  a  portal  where  the  actors  involved  must  sign  in  and  communicate,  share information, and eventually create a behavior, a routine for this association and division of  the  actors  following  the  end  of  the  project.  The  technology  could  help  the  involved from  the  beginning  of  the  project,  already  in  the  model  stage,  break  down  and  prevent any construction barriers when the building has been placed in the works.

Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.
