Design and Analysis of an All-optical Free-space Communication Link

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

Fria Kriget och Gerillakrigföriing : - en kategorisering

To be able to research the chain of development and its causes within military doctrines you need to describe the change and categorize it to make it understandable.This essays intent is to categorize a phenomenon within the Swedish doctrine to make it available for further research about doctrinal development. The categories are found in two of the great theorists on guerrilla warfare due to the subjects? resemblance to guerrilla tactics and its means.The phenomenon that is to be researched is directly translated as ?the free war? which basically means the use of irregular warfare behind the enemy lines. The description of ?the free war?, by whom and when it is used, are the factors that have changed during the second half of the 20th century, and have therefore been placed into different categories.

It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency..

Bostadskonsumtion och bostadsproduktion. En studie över bostadssituationen i Stockholms stad perioden 1914-1924.

The main aim of this study is to examine the development policies of Sweden and the European Union from a postcolonial perspective. Sweden and the European Union are increasingly coming to be viewed as normative powers rather than military powers. So how does the colonial past of the western societies affect the policies of today? Are there any signs of the power structures of the past, and if so, how are these power structures manifested in the development policies of today? Since both Sweden and the European Union have come to be viewed as normative powers they are compared with each other to highlight their similarities and differences. The results of the study shows that both Sweden and the European Union can be seen as carriers of western values and interests.

Perceptions of domestic solar systems : a study on non-adopter views of a new technology

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

Jämförelser av olika former av QRA och andra metoder för riskanalys av processindustrier

When performing a QRA you have to consider a number of accident scenarios. How many scenarios you choose often determines the time and resources needed to perform the QRA. The report investigates the possibility that a QRA can be performed using only a few representative scenarios. Further it presents a discussion on how these scenarios should be constructed..

Ett kreativt samarbete

Vi ämnar, med denna uppsats, att utforska det kreativa området efter ett fenomen vi valt att kalla för Det kreativa samarbetet. Uppsatsen undersöker om huruvida en arsenal av kreatörer inom olika kompetensområden kan vägas mot den ensamma kreatörens arbetssätt. Sammanfattningsvis vill vi undersöka kombinationen av de två begreppen kreativitet och samarbete och dessas inverkan på en arbetsprocess inom kreativt skapande..

Termisk Vattenpump

 This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.

Ljuddesign för bildkonst

Detta arbete beskriver hur man ljudlägger konstfilm, hur man plockar upp ljud vid inspelningsplatsen och hur man ställer ut en flerkanalig ljudläggning av en konstfilm. Detta är de tre huvuddelarna i detta kandidatarbete, och dessa kommer att förklaras med hjälp av mitt eget tillvägagångssätt, tillsammans med problem jag stött på och hur jag löst dem. Reflektionen redogör även för betydelsen av kommunikation mellan konstnär och tekniker och hur man som ljudansvarig kan använda sin maximala kreativitet och kunskap, samtidigt som upphovsmannen ska få som hon/han vill..

Svensk vindkraft

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Simple Contact Access

Målet med projektet är att utveckla ett system där det skall gå att komma åt information från en intern databas på ett enkelt sätt med en mobil enhet. Eftersom varje enskild databas är unik så skall det gå att justera systemet enkelt genom ett administrationsgränssnitt så att det passar till varje databas. Informationen är oftast känslig och skall inte åtkommas av obehöriga användare, så den mobila enheten behöver autentiseras för att skydda informationen. Systemet kommer alltså bestå av ett par applikationer:1. Webbtjänst som skall kommunicera med databasen och skicka information till webb- och den tjocka klienten.2. Webbaserad klient, skall kunna visa data från databasen.3. Tjock klient, skall kunna visa samt uppdatera data från databasen.4. Administrationsgränssnitt som skall kunna konfigurera webbtjänsten. För autentisering av användaren används telefon ID:et och sköts automatiskt av den tjocka klienten.

Utfodring av föl före och efter avvänjning :

Swedish horse breeders have generally very few mares producing a few foals a year and the breeders have relatively few traditions, little knowledge and experience to breed foals successfully. It is therefore important to provide adequate information about new findings in horse nutrition. However, there is not much research about feeding the suckling foal to ensure a sound growth. Current feeding recommendations in the literature seems to be different. This gives a confusing message and the information is difficult to apply. This paper reviews some publications in the area of feeding the suckling and weaning foal. Most authors stress that it?s important to start feeding the foal early in life.

Studentrekrytering : det bortglömda kapitlet inom eventkommunikation

Student recruitment is a subject that seems to be forgotten in the theory of event communication. Yet the area has some specific reoccurring features. Our purpose was to examine these specific features and how to work with these in the best way, and also see how to get the most out of the event communication to the young at event and fairs. Special features we have looked at are the student ambassadors ands their impact, the meaning of a give-away and also if there are any essential factors to get in contact with the young at fairs and events, and if new technology had an important role to play in the area.Our research has been inductive, and therefore, we have created our own theory and reflected it to the larger topic of event communication and its theories. Our research method has been triangular, both quantitative and qualitative; interviews with those who work with student recruitment, and surveys to young people in upper secondary school.Our study showed the importance of student ambassadors and their specific task to be nice, friendly and outgoing.

Aktörer och artefakter : Ett samtida perspektiv på bibliotek och automatisering

This bachelor thesis examines the activities and values associated with automation and technical development at four Swedish research libraries. It does so by applying textual analysis to annual reports and job advertisements from the respective libraries. The study also questions whether some assumptions of automation have changed or remain over time, and includes a short historical discussion in relation to the contemporary analysis. As an added perspective it introduces the methods and philosophies of French sociologist Bruno Latour. The author reflects on the merits of Latour in research of library automation.

Mätning av kranskärlet LAD:s slingrighet : en pilotstudie

The background to this report is the author?s ambition to understand individuals? work situation, how it?s formed in interaction between the individual and factors in the work-setting. Such an ambition is well in line with the concept of Human-Technology-Organization (HTO), a cross-scientific approach that puts a system-oriented perspective on how human, technolog-ical and organizational factors interact within work systems.The aim of this report was to explore managers? work-situation and generate an understanding of it from an HTO-perspective by using an organizational model as a framework for an interview guide and to analyze the work situation from an HTO-perspective following the ques-tions at issue:1. How does the managers experience their work situation?2.
