Estimation of local second-degree variation should be a natural first step in computerized image analysis, just as it seems to be in human vision. A prevailing obstacle is that the second derivatives entangle the three features signal strength (i.e. magnitude or energy), orientation and shape. To disentangle these features we propose a technique where the orientation of an arbitrary pattern f i...

This paper presents the prototype development of an integrated online GIS-enabled virtual public meeting space (GeoVPMS) system using open source technologies that are still in development and early stage of testing. The prototype system is based on a GeoVPMS conceptual framework (Li et al. 2007) and features the integration of various types of open source based solutions and open map services ...

A service registry is a Service-Oriented Architecture (SOA) component that keeps a ‘catalogue’ of available services. It stores service specifications so that these specifications can be found by potential users. Discussions on the design of service registries currently focus on technical issues, while service registries should take into consideration information needs of business domain users....

The direct observation of high-energy cosmic rays, up to the PeV energy region, will increasingly rely on highly performing calorimeters, and physics performance be primarily determined by their geometrical acceptance resolution. Thus, it is extremely important optimize design, granularity absorption depth, with respect totalmass apparatus, which amongst most constraints for a space mission. Ca...

Traditional file systems allocate and tie up entire storage space at the time the file system is created. This creates a situation where one file system could be running out of space, while another file system has ample unused storage space. In such environment, storage management flexibility is seriously hampered. This paper presents virtual allocation, a scheme for flexible storage allocation...

This thesis focus on development of methods for using infrared sensors for position detection. There exists various methods where optical sensors are used to give position estimates, many utilizing multiple cameras. The overall approach in this thesis is to base a position detection sensor system on inputs from an array of infrared emitters and receivers. The signals from the emitters are refle...
