Reducering av effektförbrukning i inbyggda system med Linux

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

Viktoptimering av ett kompositchassi till en multimodal lättviktsfarkost

This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.

Råda bot på öm fot

There is something magical about shoes?They can create an irresistible desire or be the one thing that we want to get rid of the most at the end of a long day. When people by shoes the chose more out of appearance rather then comfort. The result is a fact. The feet feel tired and soar after a couple of hours and the only thoughts are about the aching feet that firmly object to the way there being treated.

Analys och utveckling av boggi till ramstyrd dumper

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.

Affekter för hållbarhet

Syftet med denna studie var att undersöka vilka samband det finns mellan värderingar, föreställningar och normer kring miljön till agerande för ekologisk hållbarhet i det vardagliga livet. Vår hypotes var att det finns samband mellan affekter kring miljöns framtid och agerande till hållbar utveckling. För att söka svar på syftet och bekräfta hypotesen har enkäter med frågor gällande individens värderingar, föreställningar och normer om miljön samt frågor om miljömässigt agerande skickats ut via e-post till 119 deltagare i åldern 23-65 år. Svarsfrekvensen var på 59 procent. Resultatet visade att det fanns ett flertal starka samband mellan miljömässiga värderingar, föreställningar och normer till individens agerande och hypotesen om att det fanns samband mellan affekter och agerande för hållbar utveckling verifierades.

Konstruktion av beslag med dörrfunktion till spridarlucka

This thesis was performed at Zetterbergs Industri AB. Zetterbergs is designing, building and mounts body systems for trucks, including dumpers and tippers. The assignment for the thesis was to design a door hinge for a spreader gate. The spreader gate is the top of the two tailgates on a dumper or tipper and opens back and outwards when tipping the cargo. The spreader gate controls the mass flow of the material being tipped.

Efter krig kommer fred : att planera för återuppbyggnad i en krigsdrabbad stad

This paper intends to provide a better understanding of how to rebuild a crisis affected area and how to plan for the inhabitants of a wounded city. It will also examine the landscape architect's tasks in this work to provide a planning perspective. The discussion of reconstruction is significant because the insight and knowledge in the subject is needed in order to help nations after a disaster. Bosnia-Herzegovina's capital Sarajevo is a city recovering from a civil war where the city's situation was complicated by an ethnic conflict that has been segregating it. The restoration of the city's structure can free people from their tragedy and make them live again.

Fiskevård och delning av fiske vid lantmäteriförrättningar : Studie av FBL 3 kap 8 §

AbstractThis bachelor thesis was performed at the Royal Institute of Technology in Stockholm on behalf of the Land Survey Authority. The thesis is about fish conservation and division of fishing water at official duty. It is the Land Survey Authority that examines division of fisheries, but before a case can be implemented, certain requirements must be achieved such as FBL 3:8, which prevent divisions that are deleterious for fish conservation. The purpose of this thesis is: to obtain a clearer view how FBL 3:8 should be applied in practice, how the application differs between the offices in central Sweden, and how fish care is regulated at both international and national levels.At an international level, in EU the commercial fishery is regulated through the common fisheries policy (CFP). The fisheries policy consists of a reform that will last for 10 years.

Idrott för alla? : Intresse och engagemang för breddverksamhet

  Aim. The aim of the study was to describe how nurses in home care experience to pursue palliative care in ordinary housing. Methods. The study had a descriptive design with qualitative approach and was carried out through semi-structured interviews with 14 nurses in home health care from two medium-sized Swedish municipalities. The material was analyzed with manifest and latent content analysis. Findings. The underlying theme that emerged in the study was: Working with palliative care in the patient´s own homes is positive but challenging. Informants describe among other things that they perceived palliative home care as meaningful and that relatives have a central role in the palliative home care since they are close to the patient around the clock. The stress that emerges from the heavy work load and the long geographic distances are described as strenuous and to affect the care in a negative way. Informants describe the home environment as challenging as it is often not adapted for care and the collaboration with the palliative team is described to be experienced as both positive and negative.

Kattrumpans undergång? : Bör begreppet gåva tolkas enhetligt i stämpelskattemässigt och inkomstskattemässigt hänseende?

HD avgjorde år 2013 två mål som ändrade rättsläget för stämpelskatt på gåva av fast egendom. Innan HD:s avgöranden kunde fastigheter stämpelskattefritt överlåtas genom gåva till aktiebolag om ersättningen understeg 85 procent av fastighetens taxeringsvärde. Idag är dock utgångspunkten att fastighetsöverlåtelser till aktiebolag ska presumeras vara stämpelskattepliktiga tillskott istället för gåvor. HD:s ändring av rättsläget har lett till en oklarhet i hur liknande överlåtelser ska bedömas i inkomstskattemässigt hänseende. I uppsatsen utreds därför om begreppet gåva bör tolkas enhetligt eller om det finns anledning att göra skillnad mellan gåvoöverlåtelser i stämpelskattemässigt och inkomstskattemässigt hänseende.För att en gåva ska föreligga krävs alltid att tre allmänna gåvorekvisit är uppfyllda.

En jämförelse mellan TLS och UAV-fotogrammetri : Inmätning av hårdgjorda ytor

At present day there are several different methods for measuring of paved surfaces.The most common methods today are measuring with a total station, the GlobalNavigation Satellite System (GNSS) and terrestrial laser scanning (TLS). Recently thedevelopment of unmanned aerial vehicles, known as drones, has increasedexponentially and today there are several ways of using drones for measuring surfacesby photographing and laser scanning.This thesis contains a comparison between the methods terrestrial laser scanning(TLS), and unmanned aerial vehicle photogrammetry (UAV). The measurements havebeen applied on two different test surfaces, one of asphalt and one of gravel. Thepurpose of the comparison is to investigate whether the airborne photogrammetry isequivalent accurate in its height levels as the terrestrial laser scanning. For thecomparison to be more extensive, these two methods have not only been comparedin precision but also in the areas of ease of use and economy.The precision was analyzed by comparing the height levels in randomly placed controlpoints on the test surfaces.

Hopfällbar hjullösning

In many products a compromise between ground clearance and the required space to store the product has to be made. This problem attracted the attention of the authors of this thesis.The objective of this project is to develop a functioning solution to a foldable wheel. The solution should be applicable to several types of product groups. A limitation for this work has been made so that the work only covers solutions for lighter vehicles.The purpose is to drive this project forward, so that a solution can be found. Furthermore the purpose of the report is to clarify how the authors proceeded to design and construct the wheel according to a fixed specification.

"Utanförskapets reservarmé": talet om Rosengård i svensk dags- och kvällstidningspress

The aim with this study has been to examine and to analyze the discourse of Rosengård in Swedish media. With the concept of discourse is meant here specific ways to speak about and to understand the world, or a part of it. In order to reach increased understanding regarding media presentations and constructions of Rosengård, I have done a study about how Rosengård has been presented in the Swedish daily and evening press during the violent acts that took place in Rosengård in the spring and summer of 2008, when youths regarding to media put cars and containers on fire, and also threw stones at fire engines and other emergency service vehicles when these had to turn out to put out the fires. The collected data, containing newspaper articles, has been analyzed on the basis of the critical discourse analysis, CDA, which is a mould of a textanalytical method. This study applies a social constructivist perspective.
