Tid- och kostnadsanalys av innerväggar
In our thesis we will compare interior walls, both bearing and non-bearing. All of thewalls analyzed are currently used in production by Skanska Construction, who is alsoour employer/supervisor for the project. The different wall types will be comparedfocusing mainly on time, cost and workability. All of these walls aside from the nonbearingwall are constructed using concrete, either prefabricated or cast on site..
Jämförelse mellan BKR/BSK och Eurokoders behandling av utmattning i traversbalkar med tillhörande svetsfogar
This report has been performed for WSP Construction Design located at Arenavägen 7 in Stockholm. WSP Construction Design is one of the leading departments in Sweden in construction solutions regarding everything from building construction to industrial building. Great competencies regarding steel, wood and concrete constructions are available within the department which is well sought.Crane girders used in the industry are exposed to large loads that vary over time that includes instantaneous lifts and the crane girders movement which lead to the phenomenon fatigue in the crane girder and its ingoing welds. A control of fatigue needs to be performed after a certain lifespan measured in time which in turn is converted to a number of loadcycles. When the number of loadcycles amounts to a greater number the input welds resistance will have been reduced and the rate of utilization thereby increased.
OLIKHETER I SKOKURATORERS BEDÖMNINGAR - EN VINJETTSTUDIE OM TOLKNING, BEDÖMNING OCH AGERANDE
From my own experience as a school counselor I have learned that the decision making processes in terms of supporting and helping the students is extremely hard and very individual. In different situations, a different approach between individuals is present. I thought about which factors effects the school counselor?s way of handling problematic situations. I soon realized that the individual has a great effect on the work itself.
Drainfill
Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.
Content marketing - Implementeringen av den moderna säljtratten och relaterad strategi
The global spread of the Internet has enabled busniesses and consumers in all industries to be better informed. Consequently, the buying process has appeared to become different from what tratditional models implies. As the buying behaviour among customers is evolving, selling companies are responding to this change. This thesis evolves around the consequences that the developing relationship between buyer and seller in business-to-business companies has led to. The topic in focus is the buzzword and phenomena "content marketing" with its marketing and selling strategy.
Konstruktionen av en diversifierad normalitet : En studie av hur det interkulturella perspektivet kan yttra sig i några förskolepedagogers didaktiska överväganden och praktik.
The aim of the present study is to describe and analyse how an inter-cultural perspective presents itself in the didactic considerations and in the practice of preschool teachers on a multiethnic preschool.The theoretical perspective upon which the study is founded is social constructivism, but in addition to this Ingegerd Municio?s idea of two existing discourses present within the institutions in the Swedish educational system, as well as René León?s concept of a diversified normality, has been used as theoretical tools and points of departure.The empirical investigation consists of a qualitative field study at a multi-ethnic preschool, where participating observation and group interviews have been used to collect data. In these teachers from the preschool have participated.The results and the analysis of the data show that an inter-cultural perspective surfaces in the didactic considerations and in the practice of the preschool teachers in their construction of a diversified normality. The diversified normality thus constructed is constituted through different social processes. I have here identified the following ones: the preschool teachers emphasize differences among the children in general, they allow that the children behave differently and they allow them to be different; they recognize ?cultural? differences, differences in origin, and frames of reference, and they recognize that the children at the preschool are bilingual..
Projekthanteringssystem
This document is a summary of my work to create a project management system for
a small firm working with computer graphics. The intention is to manage
customers, projects, images and invoices in the easiest possible way. To make
the system as flexible as possible a web-interface was chosen which makes it
possible to access the system from any computer, making it independent of any
particular operating system. The only requirement on the user environment is
that the computer must have a connection to the Internet to be able to access
the system. The different techniques that have been used to develop the project
management system is primarily Ruby on Rails and a MySQL database.
Although Ruby on Rails was completely new to me, I decided to use this
framework instead of PHP, which I
already have a good knowledge of, because of the benefits Ruby on Rails
provide.
Att förebygga och undvika fuktskador i byggnader
Efforts to achieve a moisture proof construction process have proved to be considerably complicated, despite the knowledge and awareness that now exists within the moisture field. Materials, documents, templates and checklists are designed to be accessed but are not used anyway. This may be because such effort has not been prioritized and properly requirements have not existed from the commissioner of a building.This report illustrates how the commissioner of a building project can achieve a moisture proof building process by increasing knowledge, moisture proof planning, and implementation of security moisture routines. Proposals are given on how the commissioner of a building project can work to consistently bring a moisture proof building process in all stages. The difficulty with regular moisture proof efforts, the authors believe is mainly due to the following points: Many different design solutions. Lack of experience feedback. Lack of communication. Financial incentives. Attitudes.The interviews in the report have conducted with the help of a qualitative analysis, while the survey has been done using a quantitative analytical method.
Affärsmodeller inom IP-telefoni
When communications traffic increasingly turned into data, IP telephony became a disruptive technology for the telecommunication business. IP telephony was a hot topic when voice over IP services started to become available to consumers in the 1990s. The new technology changed the rules of the game and many new actors entered the market.The purpose of this study is to describe, study, and analyze how the business models of the Swedish telecom sector developed in the middle of the 2000s. The study is delimited to the Swedish consumer market for telephony.The study is built mainly upon deep interviews with 24 prominent persons in the telecom sector in 2006. To aid understanding, two telecom companies that have been chosen to represent different kinds of actors are described and analyzed more closely.
Fotboll för alla? En diskursanalys av det engelska och det svenska fotbollsförbundets offentliga publikationer.
Women?s football has, throughout history, been subject to the resistance of man?s world. The English football association forbid women?s teams to play on the association?s grounds. This ban lasted for 50 years and wasn?t dissolved until 1971.
Implementering av IKT i förskolan : Pedagogernas syn på implementeringen

Fokus i undersökningen är pedagogernas syn på användandet av IKT i förskolans verksamhet. För att få svar på syfte och frågeställningar utfördes en enkätundersökning på fyra förskolor. Av 53 utdelade enkäter kom 22 besvarade tillbaka. Dessutom har en litteraturstudie gjorts för att se vad det står i litteraturen om implementering av IKT i förskola och skola.
Groddföretagens vägar till information. En studie hur Chalmers Tekniska Högskolas Bibliotek används som informationsresurs av tio groddföretag på Chalmers Innovation.
The aim of this thesis is to investigate the information need of the incubators that comes from Chalmers University of Technology and are situated at Chalmers Innovation. It is also of interest to investigate how Chalmers University Library covers this information need. The investigation was carried out using qualitative interviews with representatives of the incubators. They were asked questions about the perceived need of information and which type of contacts they had with the library. The result is that the incubators feel that there is a great need for business information that is hard to find.
Framtidens energieffektiva flerbostadshus
The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Älvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Älvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.
Konstruktion och design av arbetsplats - för kablagemontör
This degree project has been performed with Mega Teknik AB in Landskrona. The project has resulted in a workplace for the cable installers of Mega Teknik. The workplace contains a workbench and a cart.The first stage in this project was to make an analysis of the current workplace to identify the needs the installers had.The different principle construction proposals of how the workbench would look like and which functions it would have was made during brainstorming, in groups and alone. These proposals were compared against each other using a functional analysis that has been put up to get the principle construction that fulfilled most points in this analysis.The proposal chose for further work was a cart and a bench with a module intends, the table got a formulation that creates a better reach for the installers.This proposal was generated in Catia V5 to get a better overview of the suggested proposal.During the primary structure phase drawings over all the products were made and the components were chosen. Calculations were made and the product got the dimension required.
