Utvärdering av metoder och modeller för att simulera växlingskomfort i entreprenadfordon

Good comfort for the driver of a construction machine is crucial. Gearshift comfort is an important part of the total comfort. Volvo Construction Equipment Components has a simulation environment of the powertrain, SimPow, which is implemented in Matlab/Simulink. SimPow is mostly used for simulation of control strategies and performance. In order to be able to study gearshifting comfort, Volvo has an interest in developing new models for SimPow.

Förklaringsmodeller och behandlingsmodeller kring mäns våld mot kvinnor : En litteraturstudie

Young men who commit sexual abuse is a complex topic. This study is based on litterature on the subject and the material is processed through a qualitative content analysis. The study aims to study how the litterature describes the reasons why young men commit sexual abuse. It also aims to explore what is described to be effective treatment of young men who committed sexual abuse. The study found that most of the young men who commit sexual abuse comes from families where violence and psycohological abuse occurs. Many have themselves been victims of sexual abuse.

Introduktion av buskskikt i ungskogar

Young stands in urban forests often lack a shrub layer, though shrubs play an important structural and biological role in forests. All layers interact with one another to form a multilayered stand, in which shrubs have a vital role.In this diploma thesis, Theoretical models for forest dynamics are compared with four reference stands to detect factors, and principals for introduction of shrubs in young stands. In these stands four different ways of introduction were found. In one trees and shrubs were planted together at the same time. Shrubs spontaneous spread under a canopy of mature forest, in another.

Det är inte bara verkligheten som räknas : Hur uppfattas miljöer i 2D och 3D?

Being able to take a decision on an area you've never seen is a difficult task. It is also complicated to introduce an environment in the best way to benefit its purpose. This study focuses on the differences people notice between 2D and 3D models. To make it more concrete, the study has been linked to a case study called Ha?lsans va?g 255.

Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

Kreditklassning av aktiebolag i Sverige, en logistisk regression

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.

Produktivitet och kvalitet vid stickvägs- respektive beståndsgående förstagallring :

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

Miljöcertifieringssystemet Miljöbyggnad : Inverkan på utformningen av ett kontor

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

Mellan hjälte och vårdpaket : En etnologisk studie av möjliga funktionshinderpositioner utifrån ett crip-teoretiskt perspektiv

This thesis aims to investigate possible positions of identification for people with dis/abilities. With a theoretical basis in crip-theory it discusses the notions of power and deviance and its? importance for the formation and reproduction of ideas around the concepts of dis/ability, ableism, deviancy and normality..

Pilotmodeller till flygmekanisk simulator för JAS 39 Gripen

AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

Röjningsförbandets betydelse för avverkningsekonomin i södra Sverige :

The aim of this work is to demonstrate how the net present value (NPV) at the time of the first thinning depends on the spacing after pre-commercial thinning, and show how net value from first thinning in same stand is influenced. This study is performed with models based on non-distant dependent growth models for single trees. Two different growth models have been used, one for cleaning (pre-commercial thinning) and one for thinning. The first one yields stem density distributed over diameter classes. In the second one, (the thinning model), it is possible to choose when thinning should be done, the thinning method, thinning grade and numbers of thinning.

Nätverk och förebilder : en studie om betydelsen för entreprenöriella kvinnor

Background: Of those who start companies, only about 30 % are women. Women's companies also often have both fewer employees and lower turnover. Several efforts are therefore being made to try to influence and encourage more women to start businesses and to get them to expand. Two of these ventures are special network for women and about women entrepreneurs as role models, something that also the theories believe is very important for a more egalitarian business. While entrepreneurship is encouraged for growth in the community, it also has a male character, something that needs to be considered.Purpose: As both the EU and the Swedish government through measures such as Tillväxtverket, is investing large sums to promote networking and role models, we intended to analyze the importance of networking and role models for entrepreneurial women.

The Relationship between Internationalization and Firm Performance

Title: The Relationship between Internationalization and Firm Performance Seminar date: 5 June, 2008 Course: Masters thesis in Business Administration, Programme for Managing People, Knowledge and Change, 15 University Credit Points (15 ECTS). Authors: Cheng Hsun Chiang and Márton Pap Advisor: Dan Kärreman Key words: Internationalization, Performance, Multinationality, Degree of Internationalization (DOI), Country of Origin Purpose: To illuminate various crucial aspects of internationalization by systematically contrasting the different models of the multinationality-performance relationship and searching for underlying reasons. Methodology: Meta-analysis on previous theoretical and empirical research. Our emphasis in this paper has been put on the qualitative aspects of the previous research unlike many other conventional meta-analyses that focus on the comparison of the empirical data. Theoretical perspectives: Five main models have been developed by earlier studies to describe the relationship between internationalization and performance: positive linear, no or ambiguous relation, inverted U-shaped, standard U-shaped and S-shaped curve.

Mäns våld mot kvinnor ur ett teoretiskt perspektiv

The essay begins by asserting that the theoretical approaches of men?s violence against women are just as important to study as its extent. The purpose is therefore to analyse and compare two theoretical approaches which is done by a comparative text analysis of two texts written on the subject. The essay attempts to answer two questions; what the theoretical approaches are and how they can be understood in light of feminist theory.Previous research on men?s violence against women discuss especially three theoretical aspects.

Hållbar utveckling - paradigmskifte inom snabbmatsbranschen? : En flerfallsstudie av hamburgerrestauranger

Sustainability issues have become increasingly high-profile and important in recent decades. In addition, quality issues have come to play a central role in corporate marketing, strategy and management. The word quality can be defined differently in different contexts. This paper focuses on the concept of quality, based on the Total Quality Management perspective, which in Swedish has come to be known as Offensiv kvalitetsutveckling. Offensiv kvalitetsutveckling has been described as a theoretical framework in which an organization continually strives to meet and preferably exceed customer needs and expectations at the lowest cost through continuous improvement, and in which all members of the organization are committed and focused on the organisation's processes. The purpose of this study was twofold. First, to clarify the applicability of the theoretical model Offensiv kvalitetsutveckling as a theoretical explanatory model. Second, to explore how Max Hamburgerrestauranger AB performs according to the values in Offensiv kvalitetsutveckling. A multiple case study was conducted in order to explore these topics. The results showed that Max Hamburgerrestauranger AB is working in a dedicated and value-driven manner, aligned with the values ??that form the basis for Offensiv kvalitetsutveckling. The results also showed that the model for Offensiv kvalitetsutveckling could serve well as a theoretical explanatory model, but that the model would benefit from being developed, enriched or integrated with other models.
