Measure and algorithm

This thesis describes a quality method that was developed to measure the quality of a tool or technique based on the results it produces. Based on the results of these measurements on current carving tools, a number of areas were identified that could be improved. A new carving framework was developed to address these points of improvements, and its results were tested using the previously developed quality method. The new carving framework achieved significantly better results on all identified improvement areas.

In the multi-dimensional model of data warehouses, data drawn from multiple sources is organized into fact tables and dimension tables. Data cubes pre-compute the aggregations of measurements along combinations of dimensions to speed up the processing of Online Analytical Processing (OLAP) queries. When the underlying fact tables or dimension tables change over time, data cubes need to be incrementally maintained to reflect these changes. In this thesis, we study the problem of incrementally maintaining data cubes under slowly changing dimensions.

The research has designed a novel active truck seat suspension system for a further study of active vibration control. A 5-degree-of-freedom driver and seating suspension system model for active vibration control has been developed. A novel fast system parameter identification method from vibration measurement data has been proposed for the seat-occupant system based on the multi-objective Genetic Algorithm optimization (GA).

The purpose of the dissertation is to test and use different accuracy assessment methods to evaluate the improvement of grid DEMs accuracy when increasing resolution by popular resampling methods. Currently and building the algorithm and programs to increase the spatial resolution and accuracy of the grid DEM using Hopfield neural networks. Objects of the study are grid DEMs which are built from different methods such as: LiDar DEM, contour and field measurements. The scope of the study includes the spatial resolution and accuracy of the above grid DEMs.

This chapter describes the joint application of two soft computing methods – evolutionary algorithms and fuzzy reasoning – to the problem of adaptive distributed routing control in packet-switched communication networks. In this problem, a collection of geographically distributed routing nodes are required to adaptively route data packets so as to minimise mean network packet delay. Nodes reach routing decisions locally using state measurements which are delayed and necessarily only available at discrete sampling intervals. ...
