… a part of the frequency band. To compare the different modulation techniques, simulations of the modulations were made. The simulations were made with MatLab and Simulink. Unfortunately Simulink only supports one- and two-dimensional TCM. Therefore no good simulations of ADSL …
Modellkonstruktion och Utvärdering med ORWARE
… types with anaerobicdigestion.With ORWARE, life cycle assessment was made by simulations of various wastemanagement scenarios. A total of nine scenarios were simulated for the waste management ofthree different types of wastes: Bio sludge, fibre sludge and food waste, with three …
A numerical simulation case involving space plasma and the evolution of instabilities that generates very fast electrons, i.e. approximately at half of the speed of light, is used as a test bed for scientific visualisation techniques. A visualisation system was developed to …
… SAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ”Aircraft Rigid body Engineering Simulation”. To work …
… dimensions of the microstrip transmission lines used in the prototype system. Simulations of conceivable loads in the cavity illustrate quantitatively the reflection coefficient. Even practical measurements are made in a network analyzer and are presentedin this part. Suitable …
… techniques to compensate for a multi-bit DAC nonlinearity. High-Level Simulations of the second-order Sigma-Delta modulator single-bit feedback topology along with a Semi-Uniform quantizer are performed in Cadence. Results indicate that a 5-bit Semi-Uniform quantizer with a …
Evaluation of phosphorus leaching aftermanure application using lysimeter techniques
… clay topsoil from an experimental field in Västergötland. Three rain simulations were consecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3 mg·L clearly related to the phosphorus concentration in the soil, measured in a soil extract of …
… insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as …
Ett examensarbete om akustik- och brandkrav samt en jämförelse av energi- och fuktaspekter
… when data are lacking. U-values and thermal bridges were calculated in the simulation software Comsol. The hand calculated U-values are consistent with the data calculated in Comsol. The results show that the concrete wall has a higher heat flow than the two wooden walls …

… the design process. The project continued with strength calculations and FEM-simulations on detail-level design to verify the constructions strength and dimension of the construction elements. The FMEA-analysis were done alongside that potential errors could be constructed away …
IKT (Informations- och Kommunikationsteknologi) är något som idag präglar vårt samhälle vilket leder till att dess användningsområden numera enbart begränsas av vår egen fantasi. Att använda IKT vid kriser ser vi idag som en självklarhet, men hur ser egentligen användningen av …
