Access control has been used in many systems such as military systems and business information systems. Access control protects sensitive information based on access control policies. Thus, assuring the correctness of policies is important. For this purpose, many access control policy verification (ACPV) tools have been proposed to check the correctness of policies. Since these tools have been designed...
Under the increasing complexity and time-to-market pressures, functional validation is becoming a major bottleneck of smartphone applications running on mobile platforms (e.g., Android, iOS). Due to the GUI (Graphical User Interface) intensive nature, the execution of smartphone applications heavily relies on the interactions with users. Manual GUI testing is extremely slow and unacceptably expensive...
Based on the existing IR-UWB indoor-positioning receiving system[1], a novel charge-pump PLL receiving system with AGC is proposed to accurately estimate UWB pulse arrival time, and achieve the goal of accurate indoor ranging and positioning. Pulse rising-edge detection??APulse-broadening circuit is mainly discussed, and some new phenomena are analyzed, which can be used for narrow pulse detection...
This exploratory research specifically focusing on the relationship between Internet usage behaviors and five-factor personality traits made an effort to clarify that whether it was possible to locate certain personality trait only by behavior sample of the Internet. 571 master students were administrated with NEO-FFI-R and self-designed IUBCL. According to logistic regression analysis, relevant conclusions...
Interaction testing (also called combinatorial testing) is an cost-effective test generation technique in software testing. Most research work focuses on finding effective approaches to build optimal t-way interaction test suites. However, the strength of different factor sets may not be consistent due to the practical test requirements. To solve this problem, a variable strength combinatorial object...
