36. Mold2012 : a new gravimetric quasigeoid model over Moldova
Sammanfattning : In order to be able to use the operational Moldavian GNSS Positioning System MOLDPOS efficiently for the determination of normal heights in surveying engineering, e.g. during the construction of a road, an accurate quasigeoid model is needed. LÄS MER
37. Applications of Unsupervised Deep Learning for Analysing Time-Varying Power Quality Big Data
Sammanfattning : Continuous power quality monitoring allows grid stakeholders to obtain information about the performance of the network and costumer facilities. Moreover, the analysis of continuous monitoring allows researchers to obtain knowledge on power quality phenomena. Power quality measurements result in a large amount of data. LÄS MER
38. Regional Geoid Determination Methods for the Era of Satellite Gravimetry : Numerical Investigations Using Synthetic Earth Gravity Models
Sammanfattning : It is the purpose of this thesis to investigate different regional geoid determination methods with respect to their feasibility for use with a future GOCE satellite-only Earth Gravity Model (EGM). This includes investigations of various techniques, which involve different approximations, as well as the expected accuracy. LÄS MER
39. Self-Monitoring using Joint Human-Machine Learning : Algorithms and Applications
Sammanfattning : The ability to diagnose deviations and predict faults effectively is an important task in various industrial domains for minimizing costs and productivity loss and also conserving environmental resources. However, the majority of the efforts for diagnostics are still carried out by human experts in a time-consuming and expensive manner. LÄS MER
40. A timing approach to network-based anomaly detection for SCADA systems
Sammanfattning : Supervisory Control and Data Acquisition (SCADA) systems control and monitor critical infrastructure in society, such as electricity transmission and distribution systems. Modern SCADA systems are increasingly adopting open architectures, protocols, and standards and being connected to the Internet to enable remote control. LÄS MER
