Analys och jämförelse av SEAD-förmågorna hos JAS 39 Gripen samt en svensk UCAV år 2015

Syftet med denna uppsats är att jämföra/analysera förmågorna till Suppression of Enemy Air Defences (SEAD) hosJAS 39 och en svensk UCAV år 2015. Årtalet 2015 är valt för att flera bedömare anser att det är först vid dennatidpunkt som en Unmanned Combat Air Vehicle (UCAV) har en utvecklingsnivå som tillåter att de sätts in i SEADuppdrag.I uppsatsen redovisas vilka krav som ställs på en plattforms sensorer och bekämpningsförmåga för attgenomföra ett SEAD-uppdrag mot två utvalda typer av mål. Därefter sker en jämförelse mellan de båda farkosternasförmåga att detektera respektive bekämpa de båda målen. Resultatet visar att JAS 39 som bemannad plattform har enfördel i de fall då operationer är hårt styrda av Rules of Engagement (ROE), särskilt gäller detta vid fredsbevarandeoperationer. Uppsatsen visar även att flygplanradarns förmåga att upptäcka och identifiera markmål är beroende avinförandet av en SAR-mod.

Utveckling av Mätmetoder för Färdmotstånd

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

Befolkningstillväxtens mosaik i Umeå kommun

The purpose of this thesis is to present and analyze population developments within Umeå municipality during the period 1992 to 2012. The study also aims to discuss growth trends presented in previous papers to seek common factors and get a deeper understanding.Data for 1992, 2002 and 2012 on a sub area level supplied by Umeå municipality was used. The study shows a continued positive development across almost all sub areas, but a differing growth rate from centre to periphery, and also a diversified medium age among the inhabitants.While the city center continues to have the highest growth of population during the studied years, a recent trend seems to point to a growing popularity to settle in the outskirts of the municipality, primarily near the coast..

Evenemang : -ett vinnande koncept för regional utveckling?

Event is a phenomenon that lately has become more common, especially within the tourism industry. This essay is a study within human geography and with focus on the meaning and the design of events. The purpose with this essay is to examine and describe the concept of event and to show how events can influence a region. Falkenberg is situated in the county of Halland by the west coast and the sea and because of that a natural tourist destination. The city is a known seaside resort since the end of the nineteenth century.

Naturvärdesbedömning av Utanåfladen; En inventering av vårlekande fisk, bottenfauna och vegetation

There are several thousands shallow bays along the Swedish east coast. Most of them are disturbed by different human activities, and undisturbed bays can be considered as quite unique. In the sheltered shallow bays water warms up more rapidly than adjacent water favoring the growth of vegetation, which in turns is beneficial to spring spawning fish species like perch and pike. It is nowadays more common that coastal habitats are inventoried to facilitate future preservation and planning. The aim of this study was to investigate the shallow bay Utanåfladen (59° 53`31.38 N 19°00`44.90 E) in the north Stockholm archipelago and evaluate its habitat value.

RMA och det fasta kustartilleriet : En analys av diskussioner kring RMA och det fasta kustartilleriet.

Under 1990-talet accelererade avvecklingen av det fasta kustartilleriet. Det skedde samtidigt med implementeringen av Revolution in Military Affairs(RMA)-konceptet i Sverige, snabb militärteknisk utvecklingen och Försvarsmaktens omställning från en stor organisation med lång mobilisering till insatsförsvar med hög beredskap. Syftet med studien är att med hjälp av argumentationsanalys och kvalitativ textanalys, studera relationen mellan RMA och avvecklingen av fasta kustartilleriet, genom analys av Kungliga Krigsvetenskaps Akademiens Handlingar och Tidskrifter. Resultatet visar att fast kustartilleri spelar en viktig roll även i en värld präglad av RMA och modern teknologi. Det fasta kustartilleriet ersattes av rörligt.

Överlevnad, tillväxt och skador i planteringar av sitkagran (Picea sitchensis) efter stormen Gudrun

Sitka spruce (Picea sitchensis (Bong.) Carr) is just like Norway spruce (Picea abies) a species in thegenus picea. The natural range of Sitka spruce is a narrow strip along the west coast of North America. Itis the most coastal of all picea species, and very dependent on the mild and humid climate along thepacific coast.Sitka spruce has been grown a long time in the countries around the North Sea, particularly in GreatBritain where it currently is the most important species in British forestry. Sitka spruce has not beenplanted in Swedish forests to any large extent before the storm Gudrun in 2005. Several studies indicatethat the production of wood biomass is higher for Sitka spruce compared to Norway spruce.

EN MILJ?STUDIE OM DE GEOKEMISKA F?RH?LLANDENA I SK?RHAMN, SVENSKA V?STKUSTEN

The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.

Härnösand och E4:an - vägen som lokaliseringsfaktor

Cities have always been founded on nodes of different roads.The city Harnosand was founded where the road along the coast of north Sweden meets the sea and the calm bay of Nattviken behind the island of Harnon. Harnosand has a big historic heritage as one of the first cities in the north part of Sweden, centre of the church and education city. The incrising centralisation of Sweden and the globalication of the world have made north of Sweden to the backside of Sweden.The coun- tryside and the smaller cities don ?t live anymore. In Harnosand is big moving out and many empty spaces. In the middle of Harnosand next to Nattviken, is one of these empty spaces. This empty space next to the road of E4, that leads out in the world and Europa.

Biblioteken på Tjörn ? Biblioteksverksamheten på Tjörn under två tidsperioder.

The aim of this thesis is to describe and analyse the development of libraries on Tjörn, an island on the Swedish west coast. I have divided the thesis in two parts, one in which I will describe the libraries development between the years 1873 to 1952 in the municipality of Stenkyrka and one in which I will describe the libraries development between the years 1976 and 1985 in the municipality of Tjörn. The study is mainly based on written materials and a theoretic model will also be used in which I apply three factors, society, the libraries economy and individual actors on the library activity. The libraries in Stenkyrka during the early period were dependent of public grant from the state for their survival and the libraries were undeveloped. The society around them was poor and hardly any money or assistants came from the municipality.

Utvärdering av strömmätningar vid Höga Kusten : Strömmars betydelse för lokalisering av odlingslokaler och utformning av kontrollprogram i kustområden

A study was made to evaluate how current measurementscould help to determine how particles from fish farms are dispersed. During sixweeks of the summer 2012, two different current measurements were conducted.One of them consisted of measurements each fifth minute at 5 m and 15 m atthree locations for 14-16 days each. The other consisted of profilemeasurements at each location at four times during the period of six weeks. Forthe current measurements two instruments (model RCM 9) were used. A two weekmeasurement can give enough data to make an evaluation of how the currents at alocation will transport litter from a fish farm.

Lokalisering av vågkraftanläggningar : Metodutveckling med GIS och fallstudie Bohuskusten

In this thesis work a Geographical Information System (GIS) based methodology to identify locations suitable for the installation of wave energy converters has been developed. Parameters of importance have been identified and a GIS-database has been set up, containing data about the marine environment. In a case study of the Swedish west coast the methodology has been applied, resulting in a number of maps showing possible areas. The results show that large areas are suitable for installation of wave energy converters, from a technical and economical point of view. When consideration is taken to other interests in the area, such as navigation, fishing and environmental protection, the size of the suitable area diminishes considerably.

Vilddjuret sliter sig : En studie i etablissemangets och vänsterns attityder kring politiskt våld i en svensk småstad 1925.

In this Bachelor thesis I am going to look at attitudes towards political violence in a small town in Sweden in the 1920s. The town I have picked for this study is Kalmar situated on the east coast of Sweden. This study is a micro historic case study. The specific case is a strike at the city?s water and gas plants for higher salary.

Effektivisering av kravspecifikationsprocessen

The goal of this project was to make the requirement process at the Swedish Coastguard more effective. The first step to achieve this was done by locating bottle necks in the process with value stream mapping method. The result of this study showed that the biggest restriction in the requirement process was while examining older requirement documents to understand what elements were suitable for the particular project. This was followed by a study of literature, interviews and theory of Lean Production with the ambition to investigate how the requirement process was handled on other companies and how to improve the process on the Swedish coast guard. This led to a number of potential enhancements of the process which later was evaluated.
