… may be due to culvert losses, higher ambient temperature than the theoretical calculations and airing. Another reason that the underestimation could be due, and that will be addressed in this report is windproofness and how it can change the U-value of an exterior wall …
En fallstudie på GKN Aerospace Sweden AB, en högteknologisk tillverkningsindustri
… till kunskapsutbyte. Syftet med studien är att ta fram en föreslagen beräkningsmodell för investering i kompetensutveckling samt undersöka vilka effekter som dessa interna utbildningsdagar ger, både ur ett individperspektiv och ett organisatoriskt perspektiv. Studien består av …
… energy system changes through integration of a seasonal heat storage a calculation model has been developed in MATLAB. The heat from the seasonal storage needs to be upgraded in order to be used in the ordinary district heating network. Therefore two kinds of heat pumps have …
En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften
… The mortality rate in the old Francis turbine was 0 % according to the calculations. This could be explained to the low relative velocity, which is partly a result of the small scale turbine. The relative velocity is in this case is well below 10 m/s and a collision with the …
… is simple and easy to use, which meets the specified requirements.Tests and calculations were made to support the decisions that were taken. When the final concept was fully developed and tested, a casing was created which was formed after the inside of the machine. The casing …
En förstudie av vilka energieffektiviserande åtgärdersom kan göras på pumpstationer och reningsverk
… verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified. This involves replacement of a ventilation unit, installation of low-flow nozzles and better management of the mechanical …
Åtgärdsförslag för ett minskat energibehov i fastigheten Gävle Söder 17:10
… verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified. This involves replacement of a ventilation unit, installation of low-flow nozzles and better management of the mechanical …
… shifts at the sand core manufacturing. This has been examined and economical calculations has been made. Simulations have been done in a program called Flexsim. The Flexsim model was a simplification of the real situation which therefore affects the reliability of the result. To …
Utredning av energianvändningen och energieffektiviseringsåtgärder för Tången 2
… to implement, both constructional and technical. Results from the economical calculations suggest that there´s a connection between energy saving and investment cost. Even though the energy saving potential of a single measure is significant, it´s not cost effective if it …
… periods such as single hours. The calculated power losses from the MATLAB calculations seem to be lower than the measured power losses, which could indicate that a more complex model is needed for these kinds of studies. With a good interaction between the grid information …
… have been purchased by HAB electronics. In parallel with the modeling calculations was done, which was the basis for determine dimensions and the choice of an electric motor and gears. Prototype 1 improved gradually and led to prototype number 2, which became the final result …
… home shopping. The analyses of the environmental consequences are limited to calculations for the transports between the order assembly unit (OAU) and the home of the consumer, along with a discussion of the differences in the remaining parts of the supply chain caused by home …
en ekonomisk analys
… analysis of Norway spruce versus birch. The analysis was based on soil value calculations of different cultivation models and changes in the future. The work was based on both a literature study and measurements in naturally regenerated birch stands. The results from the …
… the market. But to reach the targets set, more than just a positive economic calculation is required. An atmosphere that supports the company's integration is needed, for which it is of great importance for management to understand the underlying sets of values that exist in the …
… and receiver to reduce the effect of inter-symbol interference. Theoretical calculations result in a method, that describe which parameters that should be scaled and how they should be scaled. Simulations are carried out in order to verify the method.
