Aspect Analyzer: Ett verktyg för automatiserad exekveringstidsanalys av komponenter och aspekter

The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.

Utveckling av mobilapplikation

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.

Utveckling av kyl- och smörjsystem för ekobilen Agilis HCCI motor

Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.

Flygsäkerhet: Människan i Organisationen En jämförande studie av två flygförband inom Försvarsmakten

Syftet med denna studie var att samla in information som kunde ge en bild av den organisatoriska situationen i Försvarsmaktens helikopterorganisation i ljuset av de förändringar organisationen genomgått sedan 1998 och de allvarliga haverier som följt efter dessa förändringar. Ett tillämpat syfte var att denna bild skulle ligga till grund för en förståelse och diskussion av flygsäkerhetsläget inom helikopterorganisationen i synnerhet och inom Försvarsmaktens flygverksamhet i allmänhet. Som ett led i processen var syftet att undersöka säkerhetskulturen, organisationsklimatet och den psykosociala arbetsmiljön genom att jämföra ett helikopterförband och ett stridsflygplansförband inom Försvarsmakten. I studien ingick sådan personal som kom i personlig kontakt med den direkta flygsäkerheten vid respektive förband, såsom flygförare, tekniker, spanare/navigatörer och operatörer/ytbärgare. En enkät delades ut till 125 personer vid de två förbanden.

Upplyst trapphus

The purpose of this thesis was to increase the understanding and discuss safety aspects in two stairwells on Nyforsgatan in Eskilstuna, where the buildings were built during the years 1965-1975. I have presented a proposal for improvement through lighting. I have through different methods, such as surveys, interviews, literature studies and observations, come to a conclusion: that there are opportunities for improvement through better lighting that allows orientation in space and creates a nice atmosphere which will remove the feeling of not being safe, e.g. dark corners and shadows. It has been an exciting process to gather enough of facts to rely on and to develop the lighting design for the environments.

Utformning av sidoområden med hänsyn till vägens livscykelkostnad

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Public Welfare vs Return on Shareholders´Equity -A Case Study of the Translation & Implementation of the Management Control Systems in Systembolaget

Background and problem: Higher and other demands are made on management control systems in organizations which have a superior non-financial objective. Systembolaget, a state-owned company with monopoly to sell alcoholic beverages in Sweden, combines two main objectives which can be considered as conflicting, one financial target and one superior non-financial public welfare target. The research questions are focused on the translation of information through the organization?s levels and if the management control system makes it possible to run the organization according to both of the two main conflicting objectives.Purpose and Delimitations: To describe, analyze and evaluate how management control can be used in an organization, which is not profit maximizing and has both non-financial and financial objectives. The essay does not try to describe or draw generalized conclusions regarding general perspectives on Systembolaget?s assignment and objectives.Method: A qualitative and evaluative case study based on interviews with five employees at different levels in Systembolaget has been carried through.

Gränsöverskridande fusioner : Hur stor betydelse kommer det tionde bolagsdirektivet att kunna få?

Det råder i dagens läge en hård konkurrens mellan såväl bolag på den inre marknaden som mellan olika regioner. Möjligheten till ökat samarbete mellan bolag från olika EU-länder är en viktig del i att stärka Europas och de europeiska bolagens konkurrenskraftighet, vilket exempelvis kan göras genom gränsöverskridande fusioner. Det tionde bolagsdirektivet är således tänkt att möjliggöra och underlätta sammanslagningar av bolag från olika medlemsländer. Den 13 december 2005 kom det dock en dom från EG-domstolen som i viss mån kan tänkas underminera tanken bakom det tionde bolagsdirektivet. I Sevic Systems-domen, uttalar nämligen EG-domstolen att det ändå, trots att det tionde bolagsdirektivet ej ännu trätt i kraft, är möjligt att genomföra en gränsöverskridande fusion mellan två bolag, även om ett sådant förfarande ej är möjligt enligt de berörda ländernas lagstiftningar.

Socionomutbildning i internationellt perspektiv : En komparativ studie av Sverige, Tjeckien, Italien och Skottland

The aim of this study was to compare educational systems in Sweden, Czech Republic, Italy and Scotland. In the light of the Bologna Declaration signed in 1999, I was particularly interested in comparing social work educations in these four countries. Especially to clarify how far they have come to fulfill the goals of the common European educational policy.Central questions asked were: How do the educational systems look like in each of the four countries? How are the social work educations organized in each of them? In what ways do the social work educations differ? How can we explain such differences?Each country in this study represents a different welfare regime, and therefore I was challenged to find out if this has an impact on the implementation of the incentives of the Bologna Declaration. By studying various documents from the European Union, documents from each country and presentations of various social work programmes, I have come to the conclusion that the differences found mainly depends on the historical and socioeconomic traditions in the countries.

Effektivisering av mindre lager

The project was conducted during a period from November 2014 to January 2015 at the company Westermo Teleindustri AB (WTE). The subject of the project was to make an inventory more efficient. The inventory was located at WTE, but was owned by the subsidiary Westermo Sverige (WSE).The inventory had a high amount of tied up capital. This was due to products that hadn?t been sold.

Erkännande och verkställighet av utländska domar : Kommer det komma en tid för full implementering av principen om ömsesidigt förtroende?

The economical and judicial cooperation that EU constitutes results in that there is an increasing amount of international disputes arising. These international disputes in turn result in questions concerning private international law. The principle of mutual trust is not only an important principle in the entire judicial cooperation but especially important in the area of private international law. The principle means that the member states have to trust each other and the different legal systems. The aim of the principle is to ensure a well functioning internal market that is permeated by free circulation and freedom of establishment.

Gas som bedövningsmetod vid slakt av slaktkyckling :

Electrical stunning is the method that has been used in Sweden to stun broilers prior to slaughter. However, for reasons of animal welfare and meat quality, research has been made in the EU to develop new stunning methods. Gas stunning is now regarded as the best alternative. In this study literature has been reviewed with focus on different gas stunning systems and observations have been made at two different slaughterhouses regarding animal welfare before, during and directly after stunning. At one slaughter plant carbondioxide was used in a two-stage system where the birds were standing on a conveyer belt during the stunning procedure.

Storbankerna på den svenska bankmarknaden : Argument för och emot infrastruktursamarbetet enligt 19 § KL

The retail banking market in Sweden is highly concentrated and oligopolistic. This has been confirmed by numerous reports from different competition authorities within the EU, for example the Swedish competition authority. A considerably high number of different sorts of competition barriers has been pointed out in these reports. The competition barriers are mainly directed to the smaller banks and the potential competition. The retail banking market in Sweden is dominated by four major banks, which together has over 80 percent of all market shares.
