Smarta Hus: Nya behov och lösningar med participativ design

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

Social-engineering ett hot mot informationssäkerheten?

Den här rapporten tar upp ett annorlunda hot mot informationssäkerheten, som inte hårdvaraeller mjukvara kan stoppa. Detta hot kallas för social-engineering, och det som gör detta hotfarligt är att de anställda och chefer i en organisation, kan hjälpa utövaren av socialengineeringutan att de själva vet om det.Det går inte att förhindra att dessa attacker sker, men man kan förhindra de negativakonsekvenserna av en sådan attack. Denna rapport tar upp hur man ska göra för att enorganisation ska kunna fortsätta med sin verksamhet, efter en attack av social-engineering. Ivärsta fall kan en attack av social-engineering innebära att ett företag aldrig återhämtar sig.Detta kan bero på att organisationen har förlorat alla sina kunder, förlorat marknads andelar,eller för att de ansvariga och viktiga personerna i organisationen har blivit dömda föroaktsamhet och sitter i fängelse.Denna rapport ska informera och få er att vara uppmärksamma och medvetna om dessahot, som ni kanske inte vet finns. Ni ska få kunskap och lära er känna igen de olikaförklädnaderna en utövare av social-engineering antar..

Konstruktion av en autonom vindstation

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

AB Bofors betydelse för skolväsendet i Karlskoga

The aim with this study is to explore if and how linguistic learning takes places when four pairs ofstudents in grade one writes on the computer. Observations of eight students took place duringtwelve lessons to investigate what happened during their writing processes. This study isimportant because students? computer writing is a relatively new phenomenon in the Swedishprimary school.It is clear that the peer collaboration creates a complex interaction that becomes the platform, andalso the prerequisite, for successful language training. The method can clearly give students profitsin their linguistic development.

Anställdas förvärv av värdepapper : Beskattningstidpunkten när förvärvet är förenat med förfoganderättsinskränkningar

It has become increasingly simple for companies to offer its employees shares in the form of incentive or option plans to acquire.  Companies motivate incentive plans with employee buy-outs that it will lead to higher involvement of work. The offers are often associated with disposal restrictions to the employee such as not immediately dispose of shares or that the employees will have to remain of employment within a certain timeframe. The problems with disposal restrictions are that it makes it difficult to determine the point of taxation.When shares deemed acquired at the time of share subscription the benefit will be taxable as income from service and the increase in value income from capital. When shares are deemed to be acquired only after cessation of disposal restrictions this will result in that the benefit is taxed only once.After the Supreme Administrative Court rulings in 3167-09 and 3168-09, it is now obvious that the acquisition is deemed to occur at the time of acquisition. The problem is not yet solved because the constant development of the security market needs to be considered.

EU:s vapenembargo gentemot Kina - Orsaker till Frankrikes agerande för ett avvecklande av vapenembargot

France is committed to its ambition to lift the European Union's arms embargo imposed on China after the Tiananmen Square Massacre in 1989. France is of today the only member state that is acting to lift the arms embargo, evoking questions of motives behind its behavior. The underlying assumption in this essay is that France's actions reflect a need to find new ways of adapting itself and surviving faced with the threats of its decreased international influence. By using three different perspectives ? realism, liberalism and constructivism ? this essay examines three possible models of analysis to explain France's behavior.An analysis of the discourse covering this essay´s topic between 1989-2007 provided the basis of the paper.

Distriktssköterskans möte med föräldrar som ställer sig tveksamma till MPR-vaccination

Vaccination as a part of the preventative public health project has for many years been one of the important tasks of the children's health care. The vaccination program has been adjusted to current research and the health situation in the country. Having their children vaccinated is not something obvious for all parents, though. Especially the vaccination against measles, whooping cough and German measles have been questioned. The purpose of this literature study was to investigate the reasons for the resistance to vaccinate and to illuminate the security creating advice of the nurse at the public health centre.

Relativ deprivation och brottslighet i folkhemmets Sverige 2002-2012

There is a known link between relative deprivation and street crime among market liberal countries. Although some research has been done with cross-national data, there is none to suggest that the observed link is as valid in a country well known for its extended welfare and generous social expenditure like Sweden. The following study uses longitudinal data to see if this recognized link between relative deprivation and street crime also stands in a country with almost a century long tradition of striving for social-, economic- and cultural equality. Even though Sweden, over the last decade, has been subjected to a series of deregulations due to policy changes at national level, and with a following rise in inequality, it is still considered to be one of the most equal countries in the west. It is therefore not unlikely that the high degree of social security will reduce the negative impact of relative deprivation on social relations among its citizens, perhaps enough so that the correlation will be significantly weakened.

Granskning och optimering av data- och IP-telefoninätverk

The company Västra Mälardalens Kommunalförbund, VMKF, wishes to revise and optimize their present data and IP-telephony network as of today consists of the three municipalities Köping, Arboga and Kungsör. As a municipal corporation, they seek consultation regarding internal as well as external review and investigation of the main structure of the network, its functionality and safety. By today?s increasing demands of Internet accessibility, availability of services and security far more extends the requirement of a complete network design. The foundation of networking rests on the balance between each of these necessities.

Digitala signaturer - ett verktyg för säkerhet?

Statliga myndigheter använder i allt större utsträckning öppna system, så som Internet, i sin kommunikation med medborgare, företag och andra myndigheter, därmed ställs allt högre krav på säkerhet och tillit. I takt med den ökade användningen av elektronisk kommunikation uppstår nya problem. Några av dessa är att vi inte med säkerhet vet vem vi kommunicerar med, vem som beställer tjänster och att vi inte kan vara säkra på att information kommer till rätt person eller har ändrats på vägen. Verktyg som finns för att lösa dessa problem och öka säkerheten är digitala signaturer och elektronisk identifiering. Med detta som bakgrund ställde vi oss följande frågor, vilken teknik ska statliga myndigheter använda för elektronisk identifiering och signering? Vilken teknik ska användas för att uppfylla kraven på säker elektronisk överföring? Kan statliga myndigheter ersätta traditionella namnunderskrifter med kvalificerade elektroniska signaturer? Syftet med vår uppsats blir därför att i första hand redogöra för hur statliga myndigheter avser att ersätta traditionella namnunderskrifter med kvalificerade elektroniska signaturer. Genom litteraturstudierna skaffade vi oss kunskaper om både teknik och användningsområden för digitala signaturer och genom att beskriva dessa tekniker får läsarna en introduktion i ämnet.

Derivativ talan och Corporate Governance. En komparativ studie ur ett rättsekonomiskt perspektiv

The world is getting smaller. Global markets, political processes and communication technology bring people together. Even though many of these processes are dynamic and constructive, they have also resulted in a need for better and more effective ways of international conflict resolution. This thesis investigates central issues connected to the concept of humanitarian interventions in relation to current and future legislation of the European Union. The overall question is whether the rapid globalization process has resulted in a change of international law towards more liberal view where authorization of the security council is not always needed? And, if there has actually been such a liberalization, how does that affect the legal possibilities for the European Union to carry out armed operations without the consent of the global community?The conclusion of the thesis is that international law has been modified mainly in two aspects: First, the concept of sovereignty is no longer seen merely as a right of the nation, but also as a responsibility.

Does Party Politics Matter? - En hypotesprövande studie om USA:s partipolitiska position till europeiskt säkerhetssamarbete

In his recent article Professor of International Affairs Charles Kupchan claims that Party Politics has become increasingly important for American Foreign Policy since the end of the Cold War. This assertion makes it valuable to assess how the substance of the Foreign Policy differs between the two American parties in various cases and if this difference is characterized by consistency or by change. In this thesis I examine these Party positions in relation to the European Security Policy.In order to examine this I compare the positions of the Democratic and Republican Parties? policy concerning both the European Defence Community (EDC) and the European Security and Defence Policy (ESDP). The purpose of this thesis is to examine the hypothesis that the Democratic Party to a higher extent than the Republican Party is more concerned to maintain good relations to Europe respectively EU.The results show that there are small indications that my hypothesis concerning the two parties is valid.

Naturlig haptisk kraftåterkoppling från volymdata

As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.

Meddelartrygghet : För privatanställda på offentligt finansierade jobb

This paper examines how notifies security looks for private employed workers in jobs founded by the public. The aim is to clarify the legal situation surrounding notifies law, and to analyze possible shortcomings in the law with a focus on the future.Notifies law is based on five cornerstones. Where freedom of information, a right to provide information to the media for publication, ?acquires the right? and protection to be anonymous when talking to the press goes to all workers. The other two pillars, ?a look up prohibitions? and ?retaliatory forbid? apply only to employees in the public sector.
