Alternativa energikällor för varmvattenproduktion i fastigheten Galjonen. Solvärme och kylmaskinsåtervinning

Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.

AYE, AYE, CAPTAIN : En undersökning av ansvar och beslutsprocesser inom sjöfart

Beslutsfattande är den viktigaste av alla ledningsaktiviteter. Syftet med denna studie är att undersöka hur befälhavare upplever beslutprocesserna ombord och i den omgivande organisationen. Undersökningen har gjorts genom intervjuer med tre befälhavare. Intervjuer valdes för att kunna lyssna till intervjupersonernas upplevda värld och de har varit semistrukturerade, som stöd har en intervjuguide använts. Det går i den här formen att följa trådar eller infall men också att gå tillbaka och förtydliga.

Coymo

This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

Polisens avspärrningar i samband med ordningsstörningar : PL 24 § förenlighet med EKMR art 5

This thesis has aimed to study steering process and institutionalization in the context of educational policy work. This has been conducted by using empirical material from the political decision-making process that preceded the implementation of a new national program on how principals should be educated and certified. By using an aggregated theoretical point of view containing new institutionalism and traditional Swedish curriculum theory, the process was analyzed from different perspectives. The results depict a process that contained several actors who tried to shape the principal education program differently. From the theoretical perspectives, the decision-making process could be understood as an act of both self-interest as well as trust in their own beliefs and cultural values.

ITS under byggtid - utvärdering med dynameq : Fallstudie: Intunnling av E4/E20 Tomteboda - Haga södra

Essingeleden in Stockholm is the most heavily congested road segment in Scandinavia and it is ofgreat importance for as well traffic within the city as for transit traffic. The capacity of Essingeledenand Norra Länken is not enough to accommodate all traffic. At times it is not moving at all, whichresults in long queues and an augmented risk of accidents. Consequently measures for increasing thecapacity on E4/E20, which will reduce congestion and the risk of accidents, are implemented byTrafikverket. In fall 2012 one lane of three at Pampas will be closed and so will the exit fromEssingeleden to Norra Stationsgatan, called Parkeringsbron.

BIM på Trafikverket : Förslag till en utvidgad investeringsprocess

2013 a decision was made that all projects at the Swedish Transport Administration shoulduse BIM (Building Information Modeling) to some extent from 2015. BIM is an approachthat allows for streamlining of projects by the use of a 3D-model created in an early stage ofthe project. The 3D-model can carry information about the facility throughout its life cyclefrom planning to management. The use of a 3D-model can help the project to detect errors inearly stages of the project when it is easy and cheap to fix the error instead of finding theerror in the construction phase when it is costly and time consuming to fix it. 3D-models alsolead to improved communication both within the project groups and with the public.

Parametriserad modell av motorprototyp med Solidworks

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

Utrikespolitiskt beslutsfattande : En studie om hur en militär intervention kunde godkännas av FN

This study in political science examines the UN adopted resolution 1970 (2011) andresolution 1973 (2011) on the basis of foreign policy decision-making. The study aims toexplain how the UN principle of Responsibility to Protect came to be legitimized for the firsttime by the UN Security Council in the Libya conflict in 2011. By a poliheuristic perspectivethe study attempt to explain Russia and China?s acting in the voting of resolution 1970 andresolution 1973. The background to the conflict in Libya 2011 is presented in the study aswell as the Security Council?s actions during the conflict, from the beginning of the conflictuntil the adoption of resolution 1973.

Rekursiv greyboxidentifiering av drivsystem i industrirobot.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data

A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..

Volvo Ocean Race Stockholm 2009 : Planeringen av ett evenemang i världsklass

It has become increasingly common for a city or region to use sporting and media events to promote themselves. But what is behind these events? What kind of organisation is necessary to plan and run them? In the summer of 2009 the internationally known Volvo Ocean Race will arrive in Stockholm. The race is eight months long and will be hosted in Stockholm for almost the whole of June. The City of Stockholm is behind the event and Stockholm?s marinas will be responsible for making sure that everything runs smoothly and on schedule.
