Radomoptimering för luftburna störsändarkapslar
These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..
Modell för idéutveckling
The purpose of this report is to create and develop a model that streamlines and helps the innovationprocess of an idea owner and also in the development of ideas.This model should be able to apply for workshops and in innovation advice or business devlopment. I used the qualitative method in my essay just to get a maximum clear data collection, where the seven respondents were included in the interviews. However, much of the information retrieved from the theory books and research/science articles, in order to answer the research/Sceince question in the best possible way.
Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :
Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.
?Varför ska vi och dem alltid säras åt?? : En religionsvetenskaplig studie med fokus på representationen av den muslimska kvinnan i en västerländsk kontext
Research shows that Muslims are often reproduced within the context that reinforces stereotyping of Muslims, see for example Otterbeck and Schielke. They are often regarded as a collective group with no distinct individuals and thereby the Islamic religiosity is portrayed as different and deviant from the more secular and private practiced Protestantism that is a common belief in Sweden.The purpose of this work is to study the already existing representation of Muslim women in a Western context, i.e. Muslim women in Sweden. This is done through an analysis of two ethnographic interviews and observational studies, written by researchers in Sweden (Karlsson Minganti and Sultan Sjöqvist) to investigate the existence of an "us and them" mindset. The two ethnographic studies which are analyzed in this work, deal with different types of Muslims: women who have been Muslims since birth and converted Muslim women.
Utbildning och ideologi-en komparativ analys av medborgerlig och politisk bildning i en svensk respektive kubansk kontext
Hunting ground graves were distinguished as a separate category during the 1930s. There is however no clear definition of what a hunting ground grave is. They have been constructed over a large area over a long period of time (200 BC-1200 AD) and their morphology varies.This paper investigates how the archaeologists have discussed the hunting ground graves since they were distinguished as a separate category until today. It investigates what concepts that have been used to define and categorize the graves as a group. It also investigates if the choices of concepts are depending on a broader societal perspective.To find the answers to these questions two surveys have been done.
Småskalig avloppsrening med membranbioreaktor och
elektrolytisk dosering av järn: en studie av Membrane Clear
Box® med P-eliminering
I Sverige fanns det 2001 drygt 850.000 fastigheter, varav 500.000 permanentboenden, som saknade anslutning till kommunala VA-anläggningar. Enligt beräkningar gjorda för år 2000 stod de enskilda avloppen för 20% av utsläppen av fosfor till den svenska naturen och 4% av de totala utsläppen av kväve. Den 1:a augusti 2006 trädde naturvårdsverkets allmänna råd om små avloppsanläggningar i kraft, vilka ska vara rådgivande för hur miljöbalken skall tolkas. Enligt de allmänna råden skall avloppsanläggningar som ligger inom hög skyddsnivå klara en reduktion på 90% för fosfor och syreätande ämnen och 50% för kväve. Hans Huber AG i Tyskland utvecklade under 2000 en membranbioreaktor som kan monteras i en befintlig trekammarbrunn, Membrane Clear Box® (MCB).
Definierade varumärken : En bildanalytisk studie av Norrlands Guld och Mariestads reklamfilmer
As a consumer often chooses product or service to satisfy the specific needs or desires. However, there is more often than not several brands that manufacture the same product, which means we also have to choose between these brands before we can calm our needs. This choice is usually an active decision. We choose a brand that we are familiar with, or a brand whose identity appeals to us. The brand thus has a major impact on both consumers' decision-making in connection with the purchase, but also for business success.
En simuleringsmiljö för distribuerad navigering
This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.
Religionsämnets utveckling inom den svenska skolan : En studie av läroplanerna i religion 1919-2011
AbstractIn this essay I examine the exegetical problems concerning the interpretation of the metaphor ???????????????? in 2 Corinthians 2:14.The regular idea of the metaphor is that the apostle Paul is using the picture of a Roman triumph to describe the apostle?s and his co-worker?s service for God. This includes that God is leading them into many sufferings finished off with a martyr death as the triumph was very painful for its prisoners and mostly ended with an execution. But since A.D 300 such an interpretation has been questioned. Scholars react primarily to the cruelty of it and ask if that really was Paul?s meaning.
MPD-vågformer för helikopterradar
A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.
Do retention trees affect the composition of ectomycorrhizal fungi? : a comparison between clear-cuts areas with and without retention trees in pine forests
Under det senaste årshundradet har de svenska skogarna genomgått en omfattande förvandling, från mer eller mindre naturligt dynamiska till hårt brukade skogar bestående av monokulturer av tall eller gran. Denna förändring har lett till en minskning av den biologiska mångfalden, att många arter som är beroende av skog har minskat radikalt och hotas av utrotning. Som ett försök att främja variation, biologisk mångfald i allmänhet och förhindra minskningen av rödlistade skogsarter introducerades i början av 90-talet en viss naturvårdshänsyn i brukade skogar. I den här studien utvärderas den påverkan som kalavverkning har och den betydelse hänsynsträd har på artsammansättningen och förekomsten av ektomykorrhizasvampar (EMF) under de första 20 åren efter kalavverkning. Studien utfördes genom extrahering och identifiering av svamp-DNA från jordprover tagna på kalavverkade ytor, nära hänsynsträd och i gammal skog i ett begränsat geografiskt område i norra Sverige.
Effektiv ekonomistyrning inom den offentliga sjukvården - en studie av Habiliterings- och rehabiliteringskliniken på Blekingesjukhuset
The purpose with our study is to investigate in which way a public field of
action has succeeded to make the economic management more effective and also
find out which factors/activities that have contributed to get the result of
the budget in balance. We also want to find out in which degree the balanced
scorecard (BSC) has contributed to the positive result of the budget.
Method: We had started out from the qualitative method theory which is based on
the hermeneutic theory, because we will interpret and understand. With this
starting point we have chosen to use a case study with semi-standardised
interviews supplemented with information from different documents, and to get
the theoretic connection we have studied literature in the subject field. The
analyse and even the theoretic connection have then started from, for this
study, a special analyse model.
Results: Througt systematic and target-concentrated management and through
cooperated factors, with stress on a leadership that is both professional,
visionary and un-combined, and there the staff´s is seen as a important
resource, and there it is a clear strategy and objective to keep the cost of
the activity within assigned budgetframe, has a public field of action, as the
clinic of hab./rehab.
Förlåtelse : Begrepp och metod inom socialt arbete
AbstractAim: this paper is a report of a concept analysis of forgiveness and its practice within the social work area. Background: worldwide interest in and funding for forgiveness research has brought about a body of knowledge from many disciplines that could be clinically useful to social work. At this time forgiveness interventions are used in social work in other countries, primary in the USA. The social workers in the Scandinavian countries need to focus on this important area of inquiry. Method: forgiveness was explored from a philosophical perspective and from forgiveness interventions from a variety of areas suitable for social work.
Att vara eller inte vara motiverad och kreativ i teaterprojektmiljö : En undersökning av motivationsfaktorer och kreativitet i en teaterorganisation.
Abstract Project as a method was defined in the American defense industry in the 1950´s and has since then developed to encompass many different areas such as industrial management, administration, research and development and IT etc. In the cultural sector project is a common way of organizing work and within theatre, which is the focus of this study, one can claim that project as a form of work has been used for hundreds of years, if not by definition.Theatre is generally assumed to be an form of art representing creativity and innovation, highly demanding from an individual perspective relative to the project result, i.e. the final performance. Time pressure, fierce competition, limited resources and responsibility to deliver on time with high quality are natural conditions given.The aim of the study is to find out what circumstances and conditions affect and have a clear impact on motivation and creativity in those working professionally within theatre.This study is based upon qualitative interviews with a limited number of employees with different occupations, within a major publicly-funded Swedish theatre institution.Contemporary research indicates both intrinsic and extrinsic motivation as essential for how we experience and commit ourselves to our work, either as two separate forces but also as they interact.Extensive studies further state our individual experience from work, the conditions provided by the organization and social environment as crucial to our work performance. A positive experience from these factors enhance our motivation and creativity.The results of this study show theatre to be an activity supported by strong visions and clear goals where challenge and creativity are essential and where it´s members show strong commitment to the task whether they are beside or on the stage..
