WLAN : Oskyddad och okontrollerad datakommunikation
This master?s thesis investigates the technology and security awareness associated with wireless networks (WLAN). It has been stated by the media and theories that many wireless networks are unprotected. This has sparked an interest to investigate the phenomenon in the Jonkoping region. The study is based on the following research questions:- What security weaknesses are present with the WLAN-technology and how can these be avoided?- How does the wireless infrastructure in the Jonkoping region look like?- Why do companies implement the WLAN-technology?- Are the companies aware of the risks involved with WLAN?We conducted this study in three steps; the first step was to hack a wireless network in a controlled environment in order to investigate the weaknesses of the commonly used security measures.
Teknologi & Numerär : Frågan om vem som vinner
The reason for this study is to settle the balance between technology and preponderance in war. Each theory claims its own superiority to be decisive when it comes to achieving military victories, but this study will show what actually happens when the two theories are analyzed together in the same conflict. To prove the conclusions, a case-study on Operation Gazelle is used. The study will describe the theories, what a military victory is and which party in the conflict came out victorious after this specific operation. Both sides? forces will be shown and compared.
Pig behaviour during crowding : a study in organic and conventional herds
Rearing in organic pig production differs from conventional rearing; pigs have outdoor access and larger space allowances. Regardless of production system all pigs are transported before slaughter and during transport pigs are crowded together in a new environment and in a space smaller than they are used to. As pigs in organic herds are reared at even larger space allowances than conventional pigs, such crowding could possibly have a stronger impact on pig behaviour and well-being. Six pig producing herds, three conventional and three organic, were visited and pigs from each herd were enclosed during 12 minutes in a test area corresponding to the crowding on a transport vehicle. During the crowding, pigs? behaviour was observed, before and after enclosure in the test area skin lesion scores were recorded, and also measures of heart girth (for weight estimation) was done.
Ett resecentrums betydelse för en stadskärna . : En studie om Kramfors resecentrums funktion och relation till den urbana omgivningen, samt upplevelsen av denna
The purpose of this study is to shed light on and describe Kramfors travel centers function and relationship to the surrounding urban environment, and how this core is experienced by residents and visitors. To do this, the use of the travel center, its relationship to Kramfors city center and the perception of it, as well as possible improvement areas has been studied.This has been examined using a quantitative method by designing a questionnaire and the usage of a research strategy through the implementation of a small-scale survey. Within this a cluster sampling was applied.The result shows that Kramfors travel centers is primarily used for traveling and is used most frequently by the visitors within the study. It is also shown that residents 'primary reason for traveling from the travel center is friends and family, followed by shopping, and that the visitors' primary motive for traveling is friends and family as well, followed by work. The mode of transportation between the travel center and destinations are mainly walking, while the mode of transport between homes and the travel center proves to be the car.
Varumärkets funktioner : Hur stark är varumärkesinnehavarens ensamrätt?
Along with the development of technology, the cross-border trade is increasing and therefore there is a need for greater consumer protection. A good consumer protection creates a feeling of safety for the consumer and that by itself may help to increase cross-border trade. This is one of the reasons for why the EU has established regulatory framework for electronic commerce, for example the Directive2000/31/EC. The direc-tive strives to create a similar law for electronic commerce within the European Union. This paper?s main purpose is to ensure that the directive is implemented properly in Swedish law, and if there are other possible ways to achieve the objective, other than the ones that the Swedish legislator has chosen.
Examining Accuracy : Drönare och drönarangrepp: retorik, praktik och historia
The military conflicts of the early 21st century have seen the introduction and rise of a new military technology: the armed drone. With the United States acting as the driving force behind this technological advancement, the U.S Air Force and intelligence agency CIA have madedrones their weapon of choice for pursuing suspected terrorists and insurgents in various remotelocations. American military leaders and policy makers assert that the armed drone?s high levelof accuracy make it the best available weapons platform for this task. However, new researchshows that the use of drones may result in more civilian casualties than previously thought, andmay in fact be more fallible than conventional aircraft in this respect.
Ögårdsparken - en gemensam park för olika kulturer genom aktivitet
Road safety is the result of measures to reduce therisk of accident and injury. (Nationalencyklopedin,2008). In principle, road safety means to arrive saveand sound.Safe traffic in cities is mainly achieved throughappropriate speed. In Sweden, more than half ofall rides happen with a speed above the legal speedlimit (Holmberg, Hydén m.fl, 1996). To reducespeed in order to increase safety requires measureswhich influence a driver?s motives for his orher choice of speed even if these are not rational(Boverket, 2002).

Metoder för att beskriva kumulativa effekter med avseende på biologisk mångfald och vägar :
Cumulative effects are seldom treated in Swedish Environmental Impact Assessments (EIA). This report treats these questions and which procedures and methods that can be used when assessing cumulative effects in EIA.
This report is a literature study where also a case study is a part. The case study shows how existing methods for cumulative effects can be used in practice. The report is concentrated on biology and treats cumulative effects on premises of biodiversity and roads.
Cumulative effects include both direct and indirect effects.
Skapande av musik förr och nu : Vad innebär vår tids teknologi för skapandeprocessen
In which ways have composing processes in music appeared over the past 300 years? How may composing processes work today? What does new technology do to this processes?The key purpose of this study is to investigate various composing processes.

Transferfunktionsmodeller modellering och prognoser av Sjötransportindex
We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.
?Out of sight, out of mind? : En studie av svenska bokbloggares inställningar till e-boken
There are experiential products that through a digital transformation wholly or partially have taken new place in our everyday lives. Just a few years ago, we had music on CDs, movies on tape and books in bookshelves. In Sweden, we are now facing a transformation when the e-book begins to take place alongside the printed book.This paper focuses on what values play a role in the attitude towards ebooks among a selected group of Swedish book bloggers. A qualitative content analysis was performed on blog posts concerning the ebook from twelve different Swedish book blogs. The posts were then coded into categories and values.
En jämförande kostnadsanalys av maskinsystem för upparbetning och transport av GROT
En kostnadsjämförelse av fyra maskinsystem för sönderdelning och transport av GROT vid avlägg har utförts för att identifiera kostnadspåverkande faktorer samt finna de mest lönsamma maskinsystemen inom hanteringskedjan för GROT. Studerade maskinsystem var TOMO hugglink med en flisbil; Skotarburen flishugg och skopbil; Huggbil med lastväxlare och containersystem; Willibald kross och dumper med containersystem. Respektive maskinsystem körs av entreprenörer från Norra Skogsägarna och fakturerade kostnader från 15 utförda trakter per maskinsystem och entreprenör har analyserats med avseende på transportavstånd och avläggstorlek. Fakturerade kostnader har sedan jämförts med kostnader beräknade utifrån ekonomiska modeller med annuitetsmetoden och vetenskapliga rapporter som grund. I modellerna har medtagits fasta maskinkostnader, maskinutnyttjande, personalkostnader, rörliga kostnader samt förväntad prestation där prestationen utgjorts av ett medeltal från minst två vetenskapliga rapporter.

Viktoptimering av ett kompositchassi till en multimodal lättviktsfarkost
This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.
