Denna rapport beskriver utvecklingen av ChalmersAppen, en applikation för smarttelefoner med operativsystemet Android. Studenter på Chalmers tekniska högskola har behov av att nå flera olika webbsidor på Internet. Med tanke på att smarttelefoner ökar bland studenter kan studietiden underlättas med hjälp av en applikation som samlar den viktigaste informationen från de mest använda webbsidorna på ett ställe. Målet med ChalmersAppen var att den skulle utföra denna uppgift och vara användarvänlig.Som underlag till framtagandet av applikationen genomfördes en enkätundersökning bland studenterna. Undersökningen visade att det fanns intresse för en sådan applikation och vilka funktioner som var viktigast att ha med.
Optimering av driftläggningar i Fortums nät
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.
Höghöjdsanpassning av BvS10 : Konceptstudie för optimering av överladdningssystem
This report relate a concept study that consider a number of different proposals to improve the overcharging system in BAE Systems Ha?gglunds tracked vehicle series BvS10, to maintain sealevel power at extreme altitude.At high altitude the power losses beacuase of the air density that decreases, which results in less fuel can be burned. The decreasing of air density also gives rise to fatigue failure of the turbocharger unless power is reduced.The proposals shall be as required by BAE Systems Ha?gglunds economically sustainable and defensible from a packing perspective. That means the selected solution must have a reasonable price tag and at the same time a minimal impact on adjacent components.The basis for this thesis is based on benchmarking of both the auto industry as the flight industry, to find inspiration and tips for improvement.Some of the concepts have after gathering facts and calculations been excluded while other solutions has been considered as workable and thus interesting for BAE Systems Ha?gglunds.Initially the current turbochargingsystem was analyzed in order to determine the starting point and thus be able to fix the current problems surrounding high altitude driving.
Att skapa ett informationssystem ? en holistisk ansats
This thesis aims to discuss how an information system and its users may adapt to each other. The main discussion is how to create an information system that is adaptable without losing its organising properties. The thesis uses a holistic approach to the topic and the areas being dealt with are information architecture, interactive information retrieval and information searching. The practical work consisted of constructing a database for Autoliv?s Research and Development branch.
Modellering av reserv- och nödkraftsystem i JAS 39 Gripen
Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.
Skotares bränsleförbrukning :
In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements.
The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials.
The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.
Vilka strategier och metoder kan vara användbara för en hållbar viktnedgång?
The purpose of the study was to examine what methods and strategies individuals use to maintain their weight loss. Another aim was to explore which factors can complicate or simplify weight loss maintenance. Fifty-four individuals who had maintained their weight loss more than a year, participated by answering a questionnaire. The questionnaire was constructed and distributed through the internet. The answers were registered in the program google docs. The participants mentioned successful methods and strategies, such as exercising regularly, the majority exercised 30 minutes at least five times per week.
Den skräckinjagande och ångestframkallande tekniken : En korpusundersökning av hur nyorden nomofobi och räckviddsångest har etablerat sig i det svenska skriftspråket
Syftet med min uppsats har varit att undersöka hur nyorden nomofobi och räckviddsångest har etablerat sig i svenskt skriftspråk. De två teoretiska utgångspunkter som jag har utgått från är dels språkets utveckling i relation till samhällets utveckling, dels hur den språkliga utvecklingen ser ut i relation till användandet av detsamma. Som metod har jag använt mig av delar från korpuslingvistiken och därmed av olika korpusdatabaser, det vill säga stora datorbaserade textsamlingar, samt av programmet Wordsmith och, i väldigt begränsad omfattning, sökmotorn Google. För att få fram hur orden har etablerat sig har jag valt att undersöka etableringen utifrån när och var jag kan finna orden samt i vilken utsträckning skribenterna har valt att omnämna dem och vilka ord som är vanliga i samband med de valda orden. Jag har även undersökt om jag kan finna tendenser till vidareordbildning, synonymer, en vidare betydelser för respektive ord samt hur utvecklingen av användandet ser ut över tid.
Ska Google eller Facebook verkligen få fälla det sista avgörandet? : En kvalitativ studie om hur rekryterare inom mediebranschen ser på arbetssökandes användning av sociala medier
In this thesis recruiter?s attitudes and usage of social media within the media business has been examined. The purpose was to find out whether a certain type of behavior in social media could or could not lead to a future employment. How much weight is put on the virtual identity and what does recruiters look for when the look someone up on the internet. Personal interviews with recruiters were done in six different media companies in Stockholm to find out how they used social media when searching and employing new employers.

Den olfaktoriska l?sningen. Lukt i Sara Stridsbergs Happy Sally
This essay examines the olfactory reading as a possible way to make sense of a fragmented novel, in this case Sara Stridsberg?s debut Happy Sally (2004). Through close reading, the essay identifies the source of the smells, who perceives it, and how this is portrayed in the text. The smell?s position in the text is understood in relation to Maurice Merleau-Ponty?s phenomenology, where the body, as created in the literary text, is considered as a source of knowledge.
Utvärdering av ett Bränslecellsdrivet Flygplan.
With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.

Patenträtt : En förbränningsmotors patenterbarhet
The Anglo-Saxon trust is not a new phenomenon, but existed as early as in the Middle Ages. The concept is customary among common-law countries, such as England the US,but unfamiliar to civil-law countries like Sweden. The person who creates the trust is called a settlor, the one who holds and administer the property is a trustee and the person who benefits from the settlement is called a beneficiary.In Sweden there is no legislation of how the trust ought to be assessed, but the need to understand it has probably increased with the internationalization.The Swedish Supreme Administrative Court has had a few opportunities to elucidate some of the uncertainties regarding trusts, but chose to abstain. With this The Swedish Tax Panel has very limited guidance from the court when they receive an application of an advance notice.A trust is not a legal entity nor a tax subject. This differs the trust from a foundation and they can not be placed on an equality from a Swedish tax perspective.In an advance notice, 2010-03-23 (dnr 103-09/D) om Inkomstskatt: Inkomst av tjänst ? värdepappersförmån, the Swedish Tax Panel equalizes the trust property with shares when determining how to tax the assets.
