Kommunikation, uppföljning och tidsplanering inom detaljprojekteringen : Hur projekteringsprocessen kan effektiviseras med små medel

Producing a building is a long and complex process. It consists of several parts, from the feasibility study and design stage onto the construction and finally the management of the building. The design process is a critical part of the process where construction plans are made. The quality of the plans affect the production phase in great extent and faulty plans can pose a risk for extra costs for all parts in the process. The cost of producing dwellings has increased the last years and the detail design process is one of many phases where improvements can mean cost savings within the whole building process.This report aims to point at parts within the detail design process which could be more efficient, regarding communication, follow-up and time planning, and to give suggestions for improvements.

Vanadinutvinning ur LD slagg

Vanadin i konverterslagg är idag ett växande problem i Sverige. Framförallt på grund av att det inte finns någon verklig avsättning för slaggen då den förbjudits som jordförbättringsmedel och då förväntade gränsvärden gällande utlakning förhindrar att den används inom andra områden såsom vägbyggnation. Det finns idag flera vanadinproducenter som använder sig av förblåsning av råjärn för utvinning av vanadin, bland andra Pan Steel i Kina och Nizhniy Tagil Iron and Steel Works i Ryssland. Det koncept som framförallt studerats i detta examensarbete bygger på att först reducera den varma LD konverterslaggen från SSAB till en vanadininnehållande metallfas. Därefter skall en vanadin-fosfor och vanadin-järn separation ske genom att selektivt oxidera vanadinet till en vanadinrik slaggfas.

Viral Facebook integration i mobilspelet Gravel

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

Anestesi av ödlor

The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.

Fenomenet Poppe, mellan scen och skratt : En studie av Nils Poppes komiska skådespeleri utifrån en fenomenologisk utgångspunkt

Scholarly research on comical popular theatre is rare in the Swedish context even though the genre has attracted large audiences throughout the 20th century. Nils Poppe is one of the greatest Swedish actors in the comical genre and he is famous for his playful acting style. With my Master?s dissertation I aim to shed some light on both the genre and this great actor. Another aim of this Master?s dissertation is to gain understanding of what causes the audience?s laughter experiencing Nils Poppe?s comical acting.

Avloppsvattenbehandling med membranbioreaktor : En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter

In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).

The behaviour of foals before and after weaning in group

Weaning is a standard procedure at most studs, and the methods of weaning varies greatly. The method used at the stud in this particular study is supposed to decrease stress. The purpose of the study was to compare the behaviour of foals in group before and after stepwise removal of their mares. Standardbred foals with their mothers were kept in three different groups at pasture (12, 11 and 11 foals, respectively, mixed sexes). They had free access to silage and the foals were fed concentrate in a creep-feeding area. By the time the foals were 5 months old, the mares were stepwise removed from the pasture.

Konstruktion av specialmaskin för orientering och positionering av nyckelämnen

The thesis in product development ? mechanical design includes 15 credits and was carried out during the spring of 2014 at Semcon in Eskilstuna. The task is to construct a special machine for positioning and orientation of a key blank found in six different shapes, the construction is a part of a larger machine for encoding the key blank where a pick- and-place device or robot pick up the key blank and deliver it further in the process. The entire construction is designed for ASSA OEM Gothenburg.In order to accomplish the project the first step was to analyze the existing solutions to similar problems on the market in a current situation analysis to create an understanding of the problem. This was followed by a flow analysis and a functional analysis to get a deeper understanding of the problem and structuring the machine's process flow and its features.

Målsättning, prognostisering och resursfördelning i en budgetstyrd bank respektive budgetlös bank: En fallstudie av två svenska banker på kontorsnivå

Speaking of budget and budgeting is almost as adding fuel to the fire. The subject evokes a lot of emotions, both positive and negative. Some might consider budgets as a bureaucratic process that won?t lead to any good. Others might find budgets as extremely helpful and necessary in a company?s planning process.

Att inte såga av den gren man sitter på : En studie av styrning i interorganisatoriska samarbeten

Background: Despite the time and money invested in relationships with other companies, it is a fact that many of them fail. Considering this, remarkably little research has been done regarding how inter-organisational relationships are controlled, given that control can function as a solution to the problems involved with collaboration, which arise since such a relation exists in the interface between organisational boundaries, where the companies? often conflicting interests and points of view meet. If one part is stronger than the other in a relationship, the weaker however tends to give way for the stronger?s will.

Optimerad styrning av kondensatorbatterier - Ny möjlighet att minska förluster med elektronisk brytteknik

Transmission of reactive power is well known to cause active power losses. Thus, newcomponents who can help minimizing these expensive reactive power flows are ofgreat interest to the power distribution companies. ABB Corporate Research hasdeveloped the first electronic power breaker. One possible application for thisbreaker is transient-free switching of capacitor banks. This could prove a usefuldistribution voltage complement to the switch-sync technique, mainly applied to transmissionvoltage level.

Analys och beräkning av emissionsfaktorer för växthusgaser

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.
