Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Förändringar i Finansanalytikers värderingsmodells- och informationsanvändning mellan 1992-2011 : En civilekonomuppsats som inriktar sig på förändringar i en finansanalytikers användande av värderingsmodeller och informationskällor mellan 1992 och 2011.

I modern tid, andra världskriget och framåt, har finansanalytikerns roll vuxit markant och dess inverkan på börsen diskuteras numera flitigt. Forskning har bedrivits flitigt utomlands om hur dem arbetar inom yrket men materialet I Sverige är dessvärre väldigt tunt. Det finns en studie från 1992 av Lars Olbert där han kartlägger svenska finansanalytikers informationsanvändning och vilka värderingsmodeller som används i praktiken och inte bara i teorin. Denna kartläggning skulle vara intressant, och releveant, att uppdatera. Därav denna studie.Syftet med denna studie är att undersöka vilken information och värderingsmodeller som svenska finansanalytiker använder vid företagsvärdering 2011 samt att kartlägga om det finns skillnader i informationsanvändning mellan 1992 och 2011.Studien utgår ifrån en kvantitativ metod där empirin samlades in genom en webenkät.

Politisk sekterism i Libanon : En fallstudie av Taif-avtalet och den konsociationella demokratins hållbarhet

Aiming to contribute to the discourse on the sustainability of consociational democracy in plural societies, this case study provides an examination of Lebanon?s power sharing model. The study begins with an evaluation of the Taif Agreement. After acknowledging its effect on Lebanon?s consociational system the function and operation of Lijphart?s four consociational elements are analyzed.

Corporate Social Responsibility - ett sätt att skapa förtroende?

This essay recognizes and criticizes a commonly held assumption that Corporate Social Responsibility (CSR) functions as a ?savings account of trust? between corporations and consumers. Based on five focus group interviews, the authors discuss how corporations that engage in society can sometimes raise and sometimes destroy the trust of potential consumers. One of our main findings is that CSR seems to raise the expectations among consumers. We then compare this phenomenon with the classical theory of the disconfirmation paradigm.

En actionberättelse : en analys av de narrativa delarna i actiondatorspelet Halo

This essay is a narrative analyze of the computer game Halo. The purpose of the essay is to see what function the narrative elements have in a computer game of the action genre. The analyze is done with a neo-formalistic approach according to the theory of David Bordwell and Kristin Thompson. The choice of game was based on it's positive reviews mentioning the story. The essay tries to give a picture of research in the field and researchers views on narratives and computer games.

betraktaren och objektet

The aim of this thesis is to study what conceptions of literature that are present in the teacher magazine Svenskläraren between the years 1985 and 2012. In other words: what is the underlying view on literature's value as a teaching aid and why should we study it in school? I relate my analysis to previous research about the use of fiction in education. A critical methodology has been used to study the material. In my results I distinguish three conceptions of literature that are present in Svenskläraren.

Flodhästens matvanor och dess lättjefulla livsstil

Flodhästen är en av Afrikas största växtätare och har ett speciellt födosöksbeteende då de endast betar på natten. Under dagen stannar de i eller väldigt nära vattendrag eller dypölar där de är fysiskt ganska inaktiva. För att klara av att endast äta en begränsad del av dygnet måste flodhästen ha olika fysiologiska, anatomiska eller beteendebaserade anpassningar till detta. Syftet med den här litteraturstudien är att reda ut varför flodhästen endast betar på natten och hur är de anpassade till detta. Att de endast betar på natten beror till stor del på att deras hud spricker om de vistas i solen för länge. Dessutom sparar de energi på att sköta sin termoreglering genom att bada istället för att svettas. De är framförallt gräsätare men det har visats att de äter blad, örter, träd och buskar i större utsträckning än som tidigare har trots.

Modellering och simulering av hydraulik för användning i hardware-in-the-loop

Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.

Konstruktion och design av hjul

The task given to us was to develop an industrial wheel with new thinking in terms of fresh design and construction, with the ability to brake. While the produced wheels of today only own the property of total braking, a wish was made to integrate the ability of directional locking.The time spent working with the project has been filled with multiple sketches of ideas and function analysis.Choices of material and ways of construction have been verified by calculations, tests and prototype building. The goal of this thesis has been to develop a unique caster with well thought-out design that would be adaptable to different areas of applications.The result was a hubless wheel with the ability of directional locking before total braking.A prototype of the wheel has been made to show the design and functions..

Evaluation of the animal welfare work performed by the licensing committees and a proposal on how to establish an enhanced animal welfare assurance program for the Swedish Trotting Association

According to the basic values of the Swedish Trotting Association the horse and its welfare should always be held in highest consideration. One part of the animal welfare work in the organization is to ensure good horse management practices by controlling all active trainers through the local licensing committees situated at the Swedish racetracks. The Swedish Board of Agriculture stated that high quality animal welfare assurance programs used by the industry organizations can be used in the risk assessment of the official animal welfare control to make the official control work more effective and the ambition of the Swedish Trotting Association is to establish an animal welfare assurance program which may be approved by the Swedish Board of Agriculture. Racehorses are exposed to welfare hazards both in their management as well as during training and racing and factors like handling, training, feedstuff, stable environment, medication and the possibility to express natural behavior all affect the welfare of the horses. The aim of the project is to investigate and evaluate the animal welfare work performed by the licensing committees and to give advice on how to improve the industry?s animal welfare control.

Hästens välfärdsproblem relaterade till utfodring

Hästen har länge varit ett användbart och uppskattat djur av människan. Ända sedan domesticeringen för 6000 år sedan har hästen använts till krig, som draghjälp och för nöje. Hästen började sin utveckling som en mindre bladätande fyrtåad häst till dagens större entåade gräsätande häst. Denna utveckling var nödvändig för hästens överlevnad med anledning av ökad konkurrens av betet och förändrat klimat. Dagens hästhållning skiljer sig från den miljö hästen levde i som vild.

Metod för analys av elförbrukning i hushåll

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

Metodik för testning av styrsystem

I detta examensarbete har en generell metodik skapats för testning av styrsystem för pumpar. Testmetodiken beskrivs med modeller som på ett strukturerat sätt går igenom testningens förberedelse och utförande. Metodiken tillämpas sedan genom en stegvis mall för hur testningen går till praktiskt.En metod för att optimera antalet tester presenteras. Denna metod minskar antalet tester genom att använda de mest prioriterade signalerna som skickas mellan styrsystem och pump. Denna prioritering sker genom en viktning av hur viktig signalen är för systemet.

Välfärdseffekten av en konkurrensutsatt tågmarknad

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

Gravitationslinser

Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..
