… in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics. Duringthe survey 58 transients was registered, of which 56 was caused from the coupling ofIN_PU4040 in HSP01. The additional two transients could not be explained by any event …

… to several parameters. Two of these parameters are low frequency band (LF) and high frequency band (HF). The conclusion of the literature study is that HR seems to be an appropriate tool to detect mental stress during short and instant stress situations. Heart rate seems less …
… clock is used to synchronize the communication and PLLs are used to provide high frequency working clocks. The feasibility of new design methodology is proved on FPGA test board and the implementation details are also described in this paper. Only standard library cells are used …

… stands in managed areas. In addition, two managed stands with an extraordinary high proportion of deciduous trees were investigated. In total 171 goat willows and 29 aspens from twelve stands were included in the study. The stand history was surveyed for each stand by studying …
Möjlig interaktion och effekt på lokal biodiversitet
… Apodemus flavicollis and Apodemus sylvaticus? The hypothesis was that high abundance of wild ungulates would inhibit the density of small forest rodents. The data was collected during field work within FoMA (Environmental Monitoring Assessment)/SLU (Swedish University of …
… to approximate the homogenous ridge/valley areas in the fingerprint. The high-dimension of the feature vectors from correlation is reduced through principal component analysis. By visualising the dimension reduced data by ordinary plotting and observing the result classification …
… smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to …
Design, simulering och experimentell verifiering
… friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based …
Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential enrichment objects on piglet’s behaviour and weight gain during …
… and magnetite points to an oxidizing ore-forming environment with relatively high sulphur activity. Finally, in order to assess the possibility of connecting two of the mined vein systems, VLF (Very Low Frequency) electromagnetic measurements were performed across the strike of …
Energibesparingsåtgärder vid blekeri 4 & 5 med jämförelse mot ny utrustning
… output than desirable; because of this, savings will decrease slightly at higher outputs. Comparisons showed that considerable amounts of energy could be saved at all positions. However the investment cost is high and therefore favorable payback times can only be seen for some …
… of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present …
En spänningsfylld simulering av elkraftsystemet vid Forsmark 3
… have been to obtain parameter values for components that are relevant for the high frequencies produced by the short rise time in lightning surges. The main conclusions are: the maximum current in the lightning discharge has the largest impact on the system voltages and surges …
… shows that the power net contains harmonics of different order and intensity. High harmonic rate is found under the transformer T-7. The problem with harmonics was not known earlier and therefore it can be assumed that there are more built-in frequency converters without filter …
