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.

Sustainable business practices : a review of eco-efficiency

The current demanding business environment requires corporations to act fast in finding effective solutions to problems given the myriad of challenges they face (Dyllick & Hockerts, 2001). The challenges include the impact of climate change on business practices, natural resource consumption, chemical pollution, technological change etc. Moreover, the forces of globalization, heightened concerns about the deteriorating quality of the physical environment and increased stakeholder power are also increasingly having a real influence on business practices (Rainey, 2008). Since 1992, the World Business Council for Sustainable Development (WBCSD) has encouraged the adoption of the concept of ecological efficiency (eco-efficiency) to support business efforts aimed at addressing some of these challenges. The aim of eco-efficiency is to reduce the amount of energy and materials used in production processes to achieve economic and environmental benefits (WBCSD, 2000).

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.

Cultural Capital? - On the view of culture and cultural policy in Lund's application process to become Sweden's European Cultural Capital of 2014.

The aim of this Master's thesis is to examine the ways in which culture and cultural policy are being articulated in the process of Lund's application to become Sweden's European Cultural Capital of 2014.I have used Dorte Skot-Hansen's three cultural political rationalities: the humanistic-, the sociological- and the instrumental rationality, as well as and Jenny Johannisson's extension of those into three cultural-political discourses, as sensitizing concepts in my analysis. The questions raised are: How are the three rationalities/discourses articulated in the chosen central documents and in the process surrounding them? Which themes and arguments dominate the chosen documents?The main objects of my study have been four texts that have been produced in the applicationprocess: a Prestudy, a Plan of action, a Broschure and a Cultural policy. Along with them local political protocols, newspaper articles and other related material have been used. The research method applied was a qualitative eclectical textual analysis with emphasis on the content and on tracing the way the rationalities were expressed in the material.The rationalities were all found to be articulated in the four texts.

Digitala objekt i neutralt format

Today there are many different Cad-applications on the market for engineers. Because of big building projects it has become more and more important to work with the same application or to have access to a neutral file type to be able to transfer files between different ones.This report studies the single objects and how they react when transferring them between ADT and ArchiCAD via the neutral type IFC. We have also been looking at problems during the transfer between and if there are some connections between these problems. Afterwards we created a neutral object model of a small country house to see if the objects appeared different. The result shows no differences.But looking at the problems that appeared during the transmissions they felt small and no logical.Today it is not possible to save in a neutral type without facing small problems.

Möjligheter att minska kväveutlakningen genom att anpassa kvävegödslingen till variationer inom stråsädesfält

Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

Webbportal för kreditlån

This report describes the development of a well?functioning and aesthetically appealing web portal and associated database for a company called Svensk Kredit & Försäkringsförmedling AB (Translated: Swedish Credit & Insurance intermediation AB). The portal will test customers' creditworthiness through another company called Business Check in Sweden AB.Administrators to the web portal have a special user interface to display all customers, to disburse the money to the customer and edit customer information. A super?user interface is available for administrators where they can change the information on all administrator accounts.Many aspects of security has been addressed because the web portal will handle personal information.

Hur man fångar elevers intresse för ämnet biologi

From interviews with biology teachers and pupils, some important factors are presented that motivates and interests pupils in biology. Some of these are varied education, commitment of the teacher, narrative skill and individually reachable goals. Other important factors are practical application and connection to daily life, as well as actuality of the subject and pupils experience of the use of learning.Circumstance around teacher and pupils will influence which factors that has the most impact. It´s up to each teacher to make a decision which factors to be used based on his or her own qualities and depending on the group they will teach.Teachers and pupils agreed about factors that will cause an interesting lesson. The pupils emphasize that variation is the most important factor.

Förenklad hantering av stämpelkort med smartphones

Today bonuscards are used widely to encourage customers to return for more purchases. Many of those bonuscards are today made of paper which is negative for the environment and since they are not very valuable they are also easy to misplace. The mobile version of these cards most often needs an active download and/or other processes before use and are therefore not so easy to use spontaneous. This project aims to make it easier to handle these bonuscards with today?s smartphones and solve the given problems.

Diagnostiksystem i gaffeltruckar

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

Studie av belagda kolvringarmot plasmasprutat cylinderfoder : Med avseende på friktion och nötningsmotstånd

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.

Interaktiv Produktpresentation åt Abu Garcia

Detta projekt har producerats i samarbete med Abu Garcia i Svängsta, Blekinge. Vårat projekt är en interaktiv produkt presentation gjord i flash med inslag av 3d, video och ljud. Våran tanke är att användaren ska kunna se hur en Ambassadeur Record fiskerulle ser ut både på insidan och utsidan, hur den fungerar och vad som gör den så unik. Det finns också video filmer som beskriver tillverknings processen, och hur man som förstagångs användare använder en Ambassadeur rulle. Design och bakgrundsljud är anpassad så att den ska väcka en känsla av fiske och fridfull utomhus miljö..

Folkbibliotekariers användning av sökverktyg på webben i referenstjänst

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

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.

Marknadsanpassning : hot eller möjlighet?

Making the work in the public sector more efficient is something that has been seen as necessary during the later years. One way to do this on municipal level has been to apply solutions former used mostly by private companies. The organisational parts have also been adjusted to existing conditions in this work of change. For example more and more municipalities have come to use the purchaser-supplier model since the beginning of the 1990's. Norrköping, Linköping and Motala have been chosen in this essay for a closer study of the effects of the changes of the 90's, from an efficiency point of view.
