Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.

Following paper deals with the questions about prehistorian and medieval settlements in the Mälar Valley and their relations to the historically known hamlets or single farmsteads from the 17th- and 18th-century cadastral maps. Models over settlement development through the period A.D 200 to 1700 done by geographers Ulf Sporrong and Dan Carlsson are tested and compared to the knowledge won by recent archaeological excavations. Is there a connection between the older settlements linked together by dry-stone walls and the late Iron Age settlements? Does the picture differ from the one presented for the Gotland region? How well are the general theories about different settlement development depending on basic natural conditions as for the potentials for cultivation and topography, corresponding to the physical remains?  Are there other factors involved when the settlement structure takes its form?The methods that are used here constitutes mainly of a comparison between different locations in the Mälar Valley that has got a well known prehistory thanks to extensive archaeological excavations. Cadastral maps, soilmaps, topography maps and maps over ancient monuments are intertwined to the same map and analyzed through works in Geographical information systems.The results of this study reveal an interesting suspicion in the continuity-question through the Iron Age.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.

De situationer och uppgifter svensk militär kan komma att ställas inför i sitt arbete att försvara Sverige vid ett väpnat angrepp och vid internationella insatser kan vara komplexa, otydliga och krävande. Dessa parametrar ställer höga krav på de chefer som skall leda förbanden. Ett av kraven är att cheferna, oavsett ledningsnivå är välutbildade och kompetenta inom just sitt område, de ska vara duktiga på just det de skall göra.Syftet med den här uppsatsen är att analysera behovet av militärteoretisk utbildning för gruppcheferna vid arméns jägarbataljon. Vad blir effekten av en sådan utbildning? Vidare var också syftet av ge förslag på vilka delar ur militärteorin en sådan utbildning skulle kunna innehålla, för att specifikt passa jägargruppchefer.Inledningsvis gjordes en analys av populärversion TOEM AJB, där förbandets uppträdande och uppgifter särskilt analyserades.

Operation Atalanta är en EU gemensam marin operation utanför Somalias kust som syftar till att skydda Word Food Program sjötransporter från piratattacker i området. Försvarsmaktens styrkebidrag till operationen består i huvudsak av Internationella Korvettstyrkan (IKS) som innehåller korvetterna HMS Stockholm, HMS Malmö och stödfartyget HMS Trossö. Förbandet transporterades till insatsområdet med strategisk sjötransport. Att transportera svenska örlogs-fartyg på detta sätt är tämligen nytt inom marinen. Strategiska sjötransporter kräver framförhållning då sjötransportresurserna i vissa fall kan vara svårt att få tillgängliga på den tid som önskas.

This study examines how management consulting firms work with business- and functional strategy and how these strategies are interrelated. More specifically we focus on business strategy (business unit level) and knowledge strategy (functional level) and whether these are aligned or not, i.e. whether strategic congruence exists.A number of recent studies have examined the importance of business strategy and knowledge strategy in management consulting firms separately, but few have pointed out the importance of the alignment between them. With this study we contribute to the strategic field of research with a model that describes how management consulting firms should work with their knowledge strategy given their business strategy. The model is developed through a synthesis between theories in the field of strategic congruence, business- and functional strategies and thereafter tested by an empirical case study of six management consulting firms.

The purpose of the work is to analyze and balance an assembly line at Fläkt Woods in Jönköping. The work is going to answer the questions about today?s throughput time, how much waste that occurs, number of staff at the assembly line, how the supply of material works and possible improvements that can be made at the work stations. The work is also going to give a proposal of improve-ments that can be made.The methods used to get the result include observations and measurements, con-versations with technicians and operators and also data from Fläkt Woods? data-base.Large variations in throughput time are measured during the measure period, from 3 hours up to 5 hours and 35 minutes.

The composing of new standards in the area of machinery safety is a continuous work which aims at writing standards that works as a tool for companies and enables them to control if the fundamental demands of security and health which is prescribed by law are reached. It is optional for the companies to choose if they want to use the standards. This report is written in cooperation with SIS and the study were performed within the technical committee SIS/TK 282. The report aims to investigating if the companies that choose to use standards see any economic advantages due to this work, how these advantages take form and where they originate. The main question formulation is how the profitability among companies that have adjusted their production to machinery safety standards are affected. The study was performed with an initial literature study which aimed at obtaining knowledge and an overview over the subject as well as investigate what former studies had resulted in.

The report is part of the university´engineer program within Industrial Organization and Economics with specialization in Logistics and Managment at Jönköping´s university.Skoghall´s mill underlies a large supply chain, which means there should be a lot of areas in need of small improvement measures. This report illustrates a small part of one of these areas and is focused on the loading distribution services in the terminal Vänern.At the moment there´s a very unequal load of the load carriers SECU box and Container at the terminal. Skoghall´s mill has the desire to equalize the high and low load levels of the 2 loading carriers named previously. One of the options to solve the problem is to set a limit of how much the carriers can load per week or per day. The mill also wants it to be investigated if the proposition would influence the customers in any way and if both the company and its customers could handle a lower level of delivery services in case the proposition was to be applied.The goal to be achieved with this thesis is to provide balance to the unequall loading of the 2 load carriers, SECU and Container, and investigate whether or not the Skoghall´s mill´s customers, could manage the lower degree of delivery service that the proposition would imply.For this goal to be achieved, random sample investigations were taken from orders of a customer that is provided with SECU load carriers and the same was made with a Container´s customer.

Due to a constantly increasing competitive pressure it is of great importance to constantly strive for improvements in order to gain competitive advantages. Lean Production is a concept that has been introduced with the aim to minimize waste and increase profitability. The purpose of this report is therefore to investigate how to perform effective planning according to the principles of Lean Production, in companys with customer exclusive products, through a case study at Sandvik Mining and Construction (SMC), and to investigate how SMC kan improve their planning of drifting rods at the production unit in Sandviken.The study started by creating a theoretical framework, to describe the subject planning and planning based on Lean Production. This frame work constituted the base for the case study which took place at Sandvik Mining and Construction, and also for the model and planning tool that has been introduced.The result of the study is partly a general model with factors that contribute to a more effective planning. These factors has beed identifed as SMED, which focuses on reducing set up times and in the end to facilitate the planning.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

The purpose with this study was to examine six caseworkers and two clients? experiences of interaction in the investigative work of social assistance. Moreover, how the interaction between caseworkers and clients are affected by the structure of the social assistance unit. The study also wanted to show how interaction rituals contribute to the change in assessment procedure in the investigative work. The study even aimed to highlight the ways in which social exclusion occurs in investigative work from caseworkers and client?s capital and gender.
