Framtiden för snabbladdning och marknadsaktörerna inom eMobilitys syn på laddinfrastruktur
The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.
Missilstyrning med Model Predictive Control
This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.
Ekoanalys-modell : En förenklad modell för att kunna belysa miljöpåverkan redan i designstadiet av en produkt
The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.
Dynamic Temporal and Tactile Cueing (DTTC) för skolbarn med komplexa uttalssvårigheter : - en interventionsstudie
Många barn har svårt att tillägna sig ett korrekt uttal och de kan uppvisa olika typer av uttalssvårigheter. Termen verbal dyspraxi används då uttalssvårigheterna är neurologiskt orsakade och den motoriska planeringen och/eller programmeringen av talets rörelsesekvenser är nedsatt. I tidigare forskning har behandlingsmetoden Dynamic Temporal and Tactile Cueing (DTTC) lett till förbättring av uttalet hos barn i 5-8 års ålder med verbal dyspraxi på stimuli (ord/meningar) som de har tränat på. Huvudsyftet i följande studie var att undersöka huruvida behandlingen har effekt på uttalet hos äldre barn med komplexa uttalssvårigheter inklusive verbal dyspraxi då behandlingen genomförs 20- 30 minuter, 3 dagar i veckan i 4 veckor. Åtta skolbarn (8-13 år) med nämnda svårigheter samt eventuell komorbiditet ingick i studien.
Externa kanaler på Prime Care : Tanken med dem, dess funktion och sättet de uppfattas på
AbstractTitle: External communication channels of Prime Care How they where thought to be, how they work and how costumers apprehend them.Number of pages: 50 (64 Including enclosures)Author: Sophie DicksenTutor: Peder Hård af SegerstadCourse: Media- and Communication Studies DPeriod: Spring 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The focus of this paper lies on the external communication channels of Prime Care and the aim is to study the following aspects: How do the channels work? How are they apprehended by customers of the company? What are Prime Cares own thoughts behind the channels? How does Prime Cares self-image correspond to the way that customers apprehend the company?Material/Method: Twenty interviews has been done with different customers of Prime Care in order to see how the company and its communication flow is apprehended. A consultant manager of Prime Care has also been asked about purposes behind the companies external communication channels in order to enable a comparison between Prime Cares image and profile. Prime Cares website, one of their mail sendouts, their salescalls, salesvisits and their exhibition participation have been studied on the basis of relevant litterature. Maletzkes model of mass communication was used as a general view of communication flow.Main results: All communication channels included in this study have different ways of function even though they all have the same main purpose, videlicet to promote the company, to inform about its activities and to recruit new customers and consultants.
Att skriva sig till läsning : Möjligheter och begränsningar ur ett pedagogiskt perspektiv
This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..
Product Development Processes in the Nordic Paper Packaging Companies : an assessments of complex processes
It is important for firms to continually develop their offerings as the business landscape develops in order to sustain their competitiveness (e.g. Schumpeter, 1934; Ansoff, 1979; Porter, 1985; Trott, 2012). In a context of globalization, rapid technology development and changing customer needs, the paper packaging industry is urged to enhance its product development activities (Hansen & Niskanen, 2007; Björkdahl & Börjesson, 2011). However, there is little research about paper packaging firms? product development processes (ibid).
Efter pesten : om återhämtningen efter pestepidemin på 1710-talet i Skåne
From 1710 to 1713 the plague raged through the Swedish province of Scania. Other studies have been made on how the disease affected the society during the epidemic. This study tries to focus on the recovery afterwards. How did the population and the farmsteads recover after the plague? Statistics from parish registers and cameral records show interesting patterns in the demography, and that the recovery was far from complete 1720.
Övervakning och detektering av sprickor i betong med en elektriskt ledande färg
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Tillförlitlighet hos trafikolycksklassificering
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Att lova guld och grön energi : En diskursanalys av svenska energibolags CSR-rapporter
The environmental situation is becoming increasingly critical. The energy sector and other industries have a big impact on our climate and the public is raising their voice for companies to admit their responsibility towards the environment and society. Companies engage in corporate social responsibility (CSR) and happily disclose their responsible performance in annual reports. But what messages are they conveying in their CSR-reporting, and what attitudes towards CSR can be found underneath the explicit content? The aim of this study is to discover which discourses exist in CSR-reports from Swedish energy companies, and how these discourses operate.
Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :
Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.
