Mutation testing is a powerful methodology for evaluating test suite quality. In mutation testing, a large number of mutants are generated and executed against the test suite to check the ratio of killed mutants. Therefore, mutation testing is widely believed to be a computationally expensive technique. To alleviate the efficiency concern of mutation(More)
(USDOT/OST-R). The mission of the UTC program is to advance U.S. technology and expertise in the many disciplines comprising transportation through the mechanisms of education, research, and technology transfer at university-based centers of excellence. Iowa State University, through its Institute for Transportation (InTrans), is the MTC lead institution.(More)
In this work, new design techniques that aim to reduce power consumption of true single-phase clock-based (TSPC) prescalers is presented. The proposed design technique is applied to a divide-by-2/3 unit, and its performance is compared with previous work to demonstrate the improvement. Simulation results show at least a 49% reduction of PDP is achieved by(More)
The functional connectivity of brain is a key point of brain network analysis. The BOLD (blood oxygen level dependent) fMRI (functional magnetic resonance imaging) signal is an effective projection signal of brain function. A dynamic method in resting-state (RS) functional connectivity analysis of brains is proposed in this paper. In contrast to traditional(More)
