Sveriges potential för elproduktion från takmonterade solceller : Teoretisk, teknisk och ekonomisk analys

The Swedish potential of electricity production from roof mounted solar panels has been determined in three steps: accessing the existing roof top areas, simulating the amount of electricity solar panels can produce on these areas and finally analyzing how large the necessary economical change is to make the solar cells profitable.The total existing amount of roof top areas are 319 square kilometers and the area distribution follows the distribution of people. This leads to an installed power of 47,9 GW which are expected to produce 49,0 TWh electricity per year. If the quality of the electricity is prioritized the highest the power is reduced to 3,7 GW, generating 3,8 TWh yearly, but if the hosting capacity is calculated from Sweden?s total electricity need, the capacity is 42 TWh per year.Today, solar panels are not profitable in Sweden for houses, even though there is a subsidy of 35 % of the investment costs, discounted in 25 years. The profitability is calculated with a cost of capital of 5 %, a price on electricity of 1 SEK/kWh and an investment cost of 20 SEK/Wp.

Den svenska lapphunden - en ras i behov av förändring?

Many pedigree dogs are suffering from inherited diseases or personality disorders caused by selective breeding. The Swedish lapphund is a breed that has been suffering from some loss of genetic variation due to the heavy use of only a few males. Concerns have arisen and crossbreeding has been discussed as a way to manage gene loss. Four breeds has been taken into consideration for this purpose; schipperke, finish lapphund, Norwegian buhund and Norwegian elkhound, black. These breeds has been tested theoretical by a comparison of mentality and health.

Det civila samhället i sandinistiska revolutionens andra kapitel Det civila samhällets demokratiska funktion i Nicaragua

This study analyzes how civil society contributes to the democratic development in a Nicaragua governed by the sandinist party FSLN. The empirical focus lays at the relationship between state and the civil society. By using a conceptual framework outlined by Caroline Boussard, the civil society is being analyzed as an actor with a democracy-building potential that is supported or constrained by a political context.The civil society is divided between traditional social movement and more newly borned NGOs. Social movements tend to approach the government comparatively to NGOs, which adopt a highly critical attitude. In contrast to NGOs, the traditional social movements are improving their democratic functions as a counterpart while NGOs confine its democratic potential to an agenda setter drawing attention to democratic deficits.

Ett pulshöjande reklammedium -Är det effektivt att exponera konsumenter för reklam i en gruppträningssal relativt i ett traditionellt reklammedium?

It appears that it has never been easier for the marketer to create and distribute advertising messages. The technical development has created new possible channels, which in addition to the traditional advertising media has resulted in consumers encountering loads of commercial messages every day. Unfortunately for the marketer, the overload of messages has contributed to an extensive advertising avoidance. This forces him to think outside the box in order to come up with attention-grabbing and innovative methods to reach out to consumers. This paper aims to examine if facilities for group exercise classes at fitness centres could be a potential advertising medium due to the unexpectedness of encountering advertising in those premises.

Användbarhet och turism, är det lätt att kombinera? : En studie om turismsajters användbarhet

In this essay we discuss the broad area of website usability from a tourism perspective. Our goal was to investigate the usability in smaller and bigger tourism websites. We have declared what website usability means and the importance of involving the users when designing a user interface. In a pilot study, we conducted three interviews with people who work with usability and then used the information we got to form questions to use in a focus group interview. In this focus group, we asked three people to assess two Swedish tourism websites, one bigger and one smaller, to find out if they were considered usable and if there was any difference in usability depending on the size of the site.

Lämna inte slumpen åt slumpen - En studie om hylloptimering i den digitala butiken

This paper examines the impact of conscious shelf management on online grocery stores. An S-O-R framework is used to unveil if some established shelf management techniques from physical stores are applicable in an online context. We also explain some of the cognitive processes customers experience as they get exposed to online buying situations. A main study with two data sources is conducted: one quantitative website experiment with 168 participants who got exposed to five different organisation patterns within five different categories; and one more qualitative eye tracking experiment with 20 participants. The results indicate that a disorganised product page evokes not only different scan paths and cognitive patterns but also generates higher sales.

Trasdocksanimering : En teknik för dynamisk animation i datorspel

En stor del av spelkänslan ingår i hur saker beter sig och hur karaktärer rör sig. Animering är ett viktigt verktyg för att åstadkomma realistiska rörelser men räcker i många sammanhang inte för att leverera en fulländad känsla av realism. I fall interaktion med omvärlden är av stor vikt kan det vara nödvändigt tillämpa tekniker för dynamisk animation, ett komplext område som har potential att öka interaktivitet i datorspel.Detta arbete presenterar en teknik för att tillåta animation att påverkas av externa krafter såsom gravitation, friktion, kollision och annat. Tekniken bygger på simulerad fysik i form av trasdockor (eng. ragdolls) som animeras genom data från animation och fysikberäkningar presenterade häri.Tekniken testades i en applikation där trasdockorna animeras samtidigt som de utsätts för externa krafter.

Informativa strukturer och egenskaper som stöd för automatiska processer i människans informationshantering

The purpose of this thesis is to create opportunities for an efficient interchange of information between humans and technology, especially for the skilled user, and put the designprincipal for informative structures and features into practice. Informative structures and features in a large number of information items helps the peripheral visual system to automatically capture knowledge through logical patterns.A field experiment was done to evaluate if informative structures and features, implicate efficient human information-processing, even in a small study. The results was ambiguous because the quantitative part of the investigation didn?t show any significant differences, whereas the qualitative showed that people prefer a dynamic document with a high degree of informative structures and features over a dynamic document with a low degree of informative structures and features. Even if this study was inconsistent, probably because to few subjects where used, the implication of the research that?s behind it is solid.

Ekologiska fotavtryck för koldioxidutsläpp för Stockholms län, Norrbottens län och Stockholms läns landsting : En kritisk metodgranskning baserad på kvantitativa data

Human existence and welfare depend on functional ecosystems. Ecosystems are critical to sustain life-support services for human well-being. One method that visualizes that humanity requires ecosystem services for resource consumption and assimilation of produced waste is ecological footprints. This study focuses on the ecosystem service carbon sequestering. A quantification of this ecosystem service showed the potential for accumulation of carbon in different ecosystems in Stockholm and Norrbotten County for the years of 1995 and 2004.

Vaktelproduktion för ägg och kött

The aim of this study is to review the commercial quail production for eggs and meat in the world. Another aim is to review the potential for increased production. Globally the quail production is very small, except in China where it is the second largest poultry industry. The production globally is small despite the quail's rapid growth, early sexual maturity and its high feed efficiency. The quail is also used as a laboratory animal and can be reared to be released in hunting areas.
