The Simulink/Stateflow is a commonly used approach in modeling embedded systems. This paper presents a model driven testing method for embedded systems using Simulink/Stateflow model, where a test model of a system constructed with Simulink/Stateflow is to be converted to hierarchical interface automata. Dependencies within hierarchical interface automata and test sequences are acquired through analyzing...
Commutation failure is a serious malfunction in high-voltage direct current (HVdc) converters and is mainly caused by ac side faults, where the change of dc current during fault conditions should be given adequate attention. Employing superconducting fault current limiters (SFCLs) for an HVdc system can suppress its dc fault current’s amplitude and maintain a small rate of the dc current change, which...
Aerial refueling is the key enabling technology to greatly increase the operation radius and loiter time for combat aircraft. Tanker aircraft becomes the important support power in the modern warfare and changes the traditional combat concept. Effectiveness analysis plays a significant part in aircraft design and operation application. Effectiveness of tanker aircraft in the aerial refueling stage...
Recent works on Information Centric Networking enable the exploitation of the caching resources in the new generation of routers (Content Routers or CR). So far, only a basic Least Recently Used (LRU) strategy implemented on every CR has been proposed. More generally, the research community lacks methods for analyzing and evaluating caching policies (other than LRU) in generic multi-cache topologies...
Simulation modeling is an increasingly popular and effective tool for analyzing transportation problems that are not amendable to study by other means. For any simulation study, model calibration and validation is a crucial step to obtaining any results from analysis. This paper proposed a systematic, practical procedure for microscopic simulation model calibration and validation. The validity of...
Thermoforming is one of the most versatile and economical processes available for polymer products. The cooling process is one of the key processes of thermoforming which effects to quality of final products. In this study, two kinds of 1-d analysis models were developed under the condition of checking the possibility of changing a 2-d to a 1-d problem in a previous study. At first, a model for stability...
