Provtryckning av passivhus - De kritiska punkterna skall bidra till att minska luftlackagen

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Animal welfare in Ethiopia: handling of cattle during transport and operations at Kera Abattoir, Addis Abeba

The main objective of this study was to evaluate animal welfare situation in Ethiopia during slaughter and to investigate chain activities between animal markets and Kera abattoir in Addis Abeba. In total, 442 animals were observed within 52 groups of cattle; both ox and calves with different breeds. The study was divided into four different sets of data collection; behavioural observations, recording of slaughter process, observation during transport and interview. During the behavioural observations, an ethogram was used with 46 behaviours observed, categorised into 5 different groups. The data was calculated using Excel and SAS. The results indicated that a significant correlation (p-value.

Implementation av Network Admission Control

This examination work is about implementation of Cisco Systems Network Admission Control (NAC) within a leading IT-company in region of Jönköping. NAC is a technique that is used for securing the internal network from the inside. NAC can verify that the client who connects to the network has the latest antivirus updates and latest operative system hotfixes. Clients who don?t meet the criteria can be placed in quarantine VLAN where they only have access to the update servers.

Tryckpulsgenerering för funktionskalibrering av mätsystem

The running of gas turbines with low emissions causes high pressure pulsations to arise in the combustion chamber. These pulsations are high amplitude sound vibrations. At some frequencies these are harmful to the gas turbine. Hence these pulsations are monitored to avoid operating conditions where pulsations are specifically harmful. It is necessary to expose the system of known pulsations to verify the functionality of the monitoring process.
