Detta examensarbete ämnar besvara huruvida Tekla Structures kan fungera som ett lämpligt 3D-modelleringsprogram för konstruktionsgruppen Nyanläggning och Bro inom Grontmij Sverige. Med goda erfarenheter av Building Information Modeling, s.k. BIM, och 3D-modellering inom andra delar av Grontmij så fanns en önskan att optimera gruppens arbetsprocesser med den senaste kunskapen inom området. Arbetet har fokuserat på att praktiskt modellera en fallstudie baserat på ett av Grontmij tidigare genomfört anläggningsprojekt. För att säkerställa fallstudiens representativitet valdes en plattrambro med stor mängd armering som ansågs ha en komplex geometri vilket potentiellt skulle fördelaktigt kunna representeras i 3D.Vid skapandet av 3D-modellen och tillhörande ritningar delades processen in i tre steg; modellering, detaljering samt visualisering.

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

The building industry are currently going through a huge alteration. The introduction of BIM (Building Information Modeling). Which also implements a lot of new ways of solving problems that building modeling can cause. This report is written for Uppsala University in cooperation with Temagruppen in Uppsala. However, it contains a comparison between two different systems that checks building models.

Hydroware Elevation Technology AB sells control and regulation equipment for hydraulic elevators. The company now wants to investigate the possibility of changing their present softstarters to frequency inverters to supply power to their pump engines. They also want to investigate the possibility of future use in so called ?intelligent? houses.The purpose of this report is to investigate these possibilities..

The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.

By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

This paper aims to shine a light on the challenges connected to the implementation of a process focused way of thinking in a public service organization. To this we have conducted a series of qualitative interviews, primarily from participants of a university driven project. The project aims to teach decision making employees of public service organizations how to use process modeling techniques to increase their efficiency. We have also interviewed the teachers who have taught the courses included in the project. As a final point of view we have also interviewed a researcher and IT consultants to compare novice users with experienced users of process modeling techniques.

Detta projekt gick ut på att under åtta veckor försöka utveckla en interaktiv tavla, där en karaktär i tavlan med hjälp av en monterad web- kamera skulle kunna interagera med tavlans åskådare. Rapporten handlar om hur man kan gå till väga för att skapa miljön till en sådan tavla, anpassad för realtidsspelgrafik.

If customers respond differently to a campaign, it is worthwhile to find those customers who respond most positively and direct the campaign towards them. This can be done by using so called incremental response analysis where respondents from a campaign are compared with respondents from a control group. Customers with the highest increased response from the campaign will be selected and thus may increase the company?s return. Incremental response analysis is applied to the mobile operator Tres historical data.

BIM, Building information modeling, anses idag som det nästa stora arbetssättet som kommer revolutionera arbetet inom byggnads- och anläggningsbranschen. Det tros att BIM kommer förändra hela branschen med allt från entreprenörer och konsulter till statens beställare. Företagen i Sverige tar ett sort ansvar för att utveckla och implementera BIM som arbetsmetod då de idag ser vinsterna som kommer komma med BIM. För BIM är inte bara ett arbetsredskap eller en teknik utan det är en helt annan arbetsmetod som kommer leda till många fördelar. Denna rapport presenterar översiktligt vad BIM är för den som inte riktigt vet vad det innebär och hur nuläget ser ut idag i Sverige inom byggprojektering och även lite i övriga världen.

Just nu pågår stora förändringar i byggbranschen. Kostnaderna för att bygga är idag för stora och branschen letar efter nya metoder för att effektivisera byggandet och minska kostnaderna. Genom att använda sig av den relativt nya Building Information Modeling-tekniken (BIM) öppnar sig flera nya dörrar för vad som är möjligt.BIM är kort sagt en digital modell där all information för hur ett byggprojekts utformning, konstruktion, utrustning och förvaltning ska hanteras. En gemensam modell skapas som arkitekten, byggnadskonstruktörer, vvs-konstruktörer, el-konstruktörer och förvaltare har tillgång till. Ändringar som görs i modellen blir direkt synliga för de andra parterna.Den gemensamma modellen ligger lagrad på en gemensam server för att underlätta kommunikationen.I produktionen har man mycket att vinna av BIM.

To challenge the competition within the construction business there are requirements ineffectiveness and use of operating computer based programs and work-methods. Thecomputer based programs are continuously improved and can at some point be the start of anew work-method. The work-method of tomorrow can be Building Information Modeling(BIM).This Master of Science Thesis gives an understanding in what BIM is and what therequirements for Sweco Theorells are in a future BIM-use as a consulting-firm. Theunderstanding is presented through a study of theory within the subject. The way of thinkingand acting among different disciplines and individuals within the building process isexplained through an interview study.The term BIM is regularly used.
