… energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used. How to achieve an energy efficient system and a pleasant indoor climate is studied …
This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program …

… envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity …
Exempel från Dalabanan.
… of different improvement for the capacity on a single-track railway. Through simulations in the software tool RailSys this report studies what effect block signals, extra meeting stations and rebuilding existing two track passing loops to three track loops have on the capacity …
En statisk och dynamisk modelldesign över VSC-HVDC för implementering i ARISTO
… as a multi-terminal one. This model is to be implemented in the power system simulation program ARISTO. The main directive of the model is operation planning and education during real-time scenarios. The model is deliberately designed as a complete and complex model but with …
ett nytt kommunikationsprimitiv för trådlösa sensornätverk
… in three case studies: the Steal the Light toy example, a Neighbor Discovery simulation and a full two-month deployment of the Lega system in the art gallery Liljevalchs. With the evaluations, Politecast is shown to be able to massively reduce the amount of traffic being …
This thesis was developed as an assignment from Ludosity Interactive where the goal was to develop a copy of the Xbox Live Indie Games-marketplace from the Xbox 360. Ludosity Interactive had a necessity to easily test a game's attractiveness to potential customers using testing …
results 9-19 years after stand establishment
Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry …
… in the Heureka module StandWise. At the end of the report the results of the simulations and different ways to increase production of quality timber of birch are discussed. Finally topics for further research are suggested.

… probably lies close to this value. The average amount of nitrogen in the simulations ranged between 9 to 19 kilogram per ha and year. Positive side-effects which follow this type of species mixture is increased frost protection and increased storm resistance for spruce. The …
kvinnan och religion i Montesquieus <em>Persiska brev</em>
… by a non-genuine religious conviction and by acts which take on a simulation form. The compliance with the religious order has little to do with religious conviction and more to do with fear of punishment and social stigma. Montesquieu also shows how Christianity can be said to …
… med riktig ammunition och fordon. Intresset för digitala krigsspel och simulationer har därmed ökat. Men för att använda sig av spel i utbildning måste man veta hur man skall använda dem. Syftet med uppsatsen har således varit att undersöka om man kan använda sig av digitala …
Analys av fem nybyggnationer
Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the …
… Stativet konstruerades i SolidWorks där även beräkningar i SolidWorks simulation genomfördes, för att påvisa att stativet skulle klara av tilltänkta externa laster. Efter godkända beräkningar skickades ritningar till Haldex för tillverkning. Då arbetet på stationen i nuläget …
… consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a …
