During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

The aim of this thesis is to answer whether a group of databases dedicated to selling books or a group of databases dedicated to lending books is more efficient. The measurements used to determine the efficiency of the two kinds of databases are Cumulated Gain and precision in modified versions. The inquiry has been conducted thus that the same 18 queries have been put forth to six databases and these results have consequently been judged according to relevance on a 4-graded scale by five respondents. The rankinglevels have then been merged to one average value per respondent and ranking. These values have then been used to determine CG/iCG/nCG and P@n per query, rank 1-10, per database and per group (the groups being STORE (BUTIK) and LIBRARY (BIBLIOTEK).

Målet med detta projekt var att hjälpa IT-Mästaren att kunna fakturera sina kunder på ett smidigare sätt. Deras dåvarande lösning av kundernas dataanvändning var tidskrävande och ineffektivt, därför ville de automatisera systemet. Det nya systemet skulle användas för att administrera kundernas servrar med hjälp av ett grafiskt gränssnitt och sedan kontakta dem för att få fram olika värden för respektive kund som ska presenteras på IT-Mästarens hemsida. På så sätt skulle de kunna fakturera sina kunder på ett mer effektivt sätt och även få bättre överblick av kundernas användning. I och med utvecklingen utav detta system så fördjupande jag mig dels i egna kända områden men jag lärde mig också nya kunskaper. Det gällde inte enbart teknisk utveckling utan också undersökning av exempelvis hämtningen av alla data som skulle göras.

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

A majority of Swedish consumers have a positive attitude towards organic production and the number of organic products on the market is increasing. Despite these positive trends, there are still relatively few consumers who choose to buy organic produced products. According to statistics, only 3% of the total sales of food consist of organic products. The aim with this essay is to understand what is needed, both from the grocery store and the consumer's point of view, to increase the consumption of organic food. Information has been collected partly through questionnaire with consumers and partly through analysis of sales statistics for a selected numbers of products. Then the empirical material have been analysed in the light of a combination of the Behavioural Perspective Model (Foxell, 1997) and Kotler's Four P:s (Kotler, 2002). Consumer's willingness to buy organic products is influenced by a number of different factors. One important thing is if the grocery store offers a behaviour setting that stimulates the consumers positive attitude and facilitates their possibilities to collect new information. Furthermore, the store needs to offer a broad and well-visualised selection of organic products.

Molntjänster är idag ett växande koncept, men det har inte vuxit så fort som leverantörerna skulle önska. Att definiera molntjänster är både enkelt och svårt. Det kan sägas vara tjänster som utförs över Internet, vilket också är den mest vedertagna definitionen. De tjänster man kanske först tänker på som molntjänster är Dropbox, Google Drive och Microsoft SkyDrive, men inom begreppet molntjänst täcks betydligt mer än så. Uppsatsen redovisar för de vanligaste begreppen och användningsområden för företag.

It is now increasingly common for organisations to work actively with HR issues. Furthermore, it is a constant top priority for organisations to remain profitable. The purpose of this study was to investigate whether so called soft HR values, as manager?s communication skills, has an actual impact on hard values in terms of costs for the organisation. Leadership is largely characterised by emotional communication, which together with personnel costs were the main focus of the research.

 AbstractThe background for this study is that there were a great amount of buildings constructed in Sweden in the years 1965-1975 in a program designed to create one million apartments in a time-period of ten years. These buildings are now, somewhat forty years later in most cases in very poor condition and the need for renovation is great and urgent. This has become a growing problem and more and more voices are being heard pointing towards the vast and extremely expensive task of renovating these buildings. Lately, it has also been more and more important for buildings to be energy-efficient and sustainable environment friendly.In recent years there has been an atempt to solve these problems by renovating such buildings but at the same time making them very energy-efficient. This is in some cases being done by isolating the shell of the building and changing the ventilation-system and so forth.

Den  ökande  risken  för  att  drabbas  av  dataintrång  ställer  allt  högre  krav  på datoranvändarens medvetenhet om de risker  och hot  som idag föreligger  i nätverk och  på  Internet.  En  väldigt  stor  del  av  datoranvändare  installerar  inte  alltid  de senaste  uppdateringarna  då  de  tillgängliggörs  och  detta  medför  att  systemen  som saknar dessa viktiga uppdateringar blir extra sårbara för hot från angripare.Tekniska  sårbarhetsanalyser  kan  vara  hjälpsamma  för  att  på  ett  smidigt  sätt uppskatta  potentiella  risker  och sårbarheter  i  ett  befintligt  informationssystem. En stor  fördel  med  många  av  dagens  sårbarhetsverktyg  är  att  de  till  stor  del  är automatiserade  och  således  inte  kräver  allt  för  djupa  kunskaper  för  att  använda, samt att de är relativt enkla att implementera.I  den  här  rapporten  har  säkerheten  i  Windows  7  och  tre  populära  programvarorundersökts.  De  tre  programvarorna  som  låg  till  grund  för  undersökningen  varOracle  Java,   Adobe  Flash  och  Adobe  Reader.  För  att  utvärdera  säkerheten  har  vi genomfört  sårbarhetsanalyser  i  syfte  att  kontrollera  hur  systemets  säkerhet påverkas,  dels  vid  installation  av  nya  programvaror,  men  även  i  systemets  skede före-  och  efter  viktiga  säkerhetsuppdateringar  .   Enklare  penetrationstester  har även genomförts  för att påvisa några av de identifierade sårbarheterna och hur de kan utnyttjas för att få full åtkomst till kritiska delar av systemet.Resultaten  i  rapporten  visar  att  det  är  väldigt  viktigt  att  datoranvändare kontinuerligt uppdaterar sina installerade programvaror och sitt operativsystem för att minska riskerna för dataintrång..

Westermo Teleindustri tillverkar och säljer telefonmodem för industritillämpningar och ska erbjuda ett konfigureringsverktyg till dessa. Verktyget ska konfigurera Westermos modem med Hayes AT-kommandon genom ett PC program som ska vara enkelt att använda så att deras supportavdelning blir avlastad från en del konfigureringssupport. Min uppgift i detta examensarbete var att ta fram en kravspecifikation och implementera en lösning utifrån denna. Kravspecifikation togs fram genom att skicka ut förfrågningar om önskemål till dotterbolag, distributörer och andra som har nära kontakt med slutkunderna. I kravspecifikationen beskrivs vilken funktionalitet programvaran skall innehålla.

Background: It has been shown that companies that lived under protected conditions for a long time have had difficulties to adapt to major changes. With that in mind an even more extensive low-cost competition in the Swedish grocery market will make a threat for the traditional grocery stores' long-term survival. The question then becomes, which strategies will be successful and lead to higher customer loyalty.Problem: Are the traditional grocery stores using strategies that can compete in addition to pricing and will those strategies lead to long-term survival?Objective: Is to analyse and evaluate two traditional grocery stores' strategies and to examine whether these are consistent with customer demand.Approach: First we have created a more fundamental understanding of the situation in the Swedish grocery market. Then we have implemented two interviews in each grocery store.

The Internet has developed into a marketplace for national and international companies. With relatively small means, a company can reach out to millions of people on a daily basis by placing itself on the Internet. With this report, we wish to suggest how e-businesses can change its strategy to adapt to the new market. Focus is on the Swedish Internet market where Swedes, resident in Sweden, trades with Swedish e-companies active within the Swedish borders. To be able to make suggestions, we will first paint a picture of the Swedish e-commerce market from statistics collected from public sources.

The purpose of this thesis is to investigate the relationship between space and consumer interaction at WEEKDAY, a contemporary fashion retail store in Malmö, Sweden. The thesis is based on a qualitative case-study and has a social constructionist approach. In order to understand the interaction taking place between consumer and environment we conducted observations guided by Kenneth Burke?s Pentad.The retail servicescape at WEEKDAY is conceived as a metaphorical stage where drama unfolds, analysing and defining the retail space using Kenneth Burke?s pentad of dramatism. We concentrate on the use of two terms of Burke?s pentad, the scene and the act, almost exclusively as we investigate how the scene stimulates the act.

Syftet med studien är att få en ökad förståelse för vilka faktorer som påverkar konsumentens butiksupplevelse. Detta för att få kunskap om hur butiker kan möta kundens behov, genom utformning av butiksutrymmet samt personalens bemötande. Studien ämnar ta reda på vilka faktorer som skapar en positiv respektive negativ respons från konsumenten. Undersökningen genomfördes genom deltagande observationer, där en person åt gången observerades och intervjuades under en shoppingtur. Detta för att ta del av både konsumentens åsikter samt agerande i miljön.Ett ord som var återkommande i samtliga deltagande observationer var struktur, då deltagarna ansåg att butikens struktur var mycket viktig för helhetsintrycket.

Aren?t you tired of never finding stuff? Take a bits as example, do you store these lose in your toolbox or carpenter belt? What if you could have it all accessible and assembled in a tool, always at arm?s reach?Today bits are used together with electric screwdrivers and handheld screwdrivers in a greater spread. For these different types of storage, from pure storage boxes to complex tools with storage built in, exist. The professional craftsmen commonly use some kind of box where the bits can be stored. Even so they tend to store their bits loose in a carpenter belt or toolbox, since they want the speed and accessibility of carpenter belt over the storage box?s tidiness.The project was started in the fall of 2010 and a referents group was early put together to ensure that the developed product became as user-friendly and attractive as possible.
