This study deals with performance issues for connecting points to a network in geographic accessibility studies. The problem is analysed by the development of a test bench where the spatial indexation methods kD-tree, Morton code and fixed grid are implemented. Using the test bench scenarios of networks, point datasets, spatial indexation methods, and methods for computing distances between poi...

Selbst mit den neuesten Modellierungswerkzeugen und dem Einzug von Objektorientierung und Abstraktion in die Hardware-Entwicklung ist der Aufwand für die Verifikation immer noch bestimmend für den gesamten Entwurfsprozess. Wiederverwendbarkeit und Flexibilität sind deshalb aus ökonomischer Sicht unabdingbar. Es wird eine SystemC-Verifikationsumgebung vorgestellt, die sich besonders für paketver...

The interoperability of train control systems is an essential feature for high-speed railways. It must be proven that the on-board system of the train control system has the ability to allow the safe and uninterrupted movement of each line, which accomplishes the specified performance. A third-party interoperability test bench should be built for the customer to test the interoperability of the...

The HEV test bench based on Controller Area Network bus was studied and developed. Control system of HEV power test bench used the CAN bus technology. The application of CAN bus technology on control system development has opened up a new research direction for domestic automobile experimental platform. The HEV power control system development work was completed, including power master controll...

Recently, there has been a proliferation of research into the acquisition of morphological grammars—that is, grammars and lexicons required for computer-based morphological analysis and synthesis. The approaches to acquiring such grammars range from tools which structure data provided by native speakers and linguists, to unsupervised machine learning. Despite this flurry of research into morpho...
