This thesis assignment at C-level is focused on calculation models and prediction methods whish can be used in the stage we call ”prospecting” of possible windmill locations. The location is southeast of Halmstad at the Farm ”Stjernarpsgods”. The rapport has two main areas …
… requirements are fulfilled. The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions. The calculations are based on different models, both old and new. There are many alternative ways to handle the …
Utformning och dimensionering av momentstyva ramhörn och 3D-modell framtagning
… frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated. Based on the maximum torque, of 973,86 kNm …
En studie av BREEAM Communities praktiska tillämpning i svensk stadsbyggnad
… carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed. Besides the comparison of the standards there’s …
Analys av skillnader mellan BBK 04 och Eurokod 2 med tillämpning av svenskt och danskt nationellt annex
… carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed. Besides the comparison of the standards there’s …
Utveckling av modell för dokumentation och elkvalitetsberäkningar
… companies use the software dpPower developed by Digpro AB to perform network calculations on their grids to ensure that the power quality meets established requirements. The program does not include any customized tools to manage distributed generation, which this project aims …
En analys med hjälp av Tekla NIS
… for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic …
Utvärdering av tillämpbarhet av modell från Highway Capacity Manual 2000 med uinderlag från busstrafik i Stockholms innerstad
… Stockholm County initiated 2015 a project with the purpose of simplifying the calculation of bus stop capacities. A hypothesis (set up by the Transport administration) based on that a model for calculation of bus stop capacities could be calibrated for Stockholm conditions is …
… a 2D ? analysis tool developed at REINERTSEN. It was seen that results from calculations involving the PIPE20 element differs from the expected results. When the rotation is small and the cross ? section is almost completely elastic the expected value and PIPE20 element output …
… been available in the model. The nitrogen flow was modeled and calculated. The calculation was made from figures given by literature, for example plant growth. The results from the model showed that there were no nitrogen leakage. In the results from the calculation, there were …
Med en undersökning av hårdvaxolja som diffusions-/konvektionsspärr
… consists of a number of power and mass balances over one day. The key to the calculations in the model is the calculation of the alfa-value. The alfa-value together with the power in the hot water condenser gives an iterative calculation. The hot water accumulator is then either …

… were used to be able to adjust the parameters and to be able to do future loss calculations in Matlab. The minor part model was made with the programs Matlab and Comsol with a loss simulation to calculate losses in the material. The main conclusion of this projekt is that with …
En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
… with different routing principles of heat pipes depending on the facility. All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions. These models are then compared to the models but with …
… empirical data. The performed simulations show the importance of a correct calculation of the wave base. This is due to its influence on the division between surface and deep water as well as the division of areas of accumulation and areas of erosion and transport. The retention …
