The first robot vacuums might be realized sooner if their designs sacrifice some efficiency for robustness achieved by persistence, and if they can expect reasonable cooperation from the household. In many houses, there are times when each room is unoccupied long enough to permit its being vacuumed without disrupting normal family life. Sacrificing sophistication to achieve minimal competence e...

Abstract This paper will solve one of the fractional mathematical physics models, a one-dimensional time-fractional differential equation, by utilizing second-order quarter-sweep finite-difference scheme and preconditioned accelerated over-relaxation method. The proposed numerical method offers an efficient solution to equation applying computational complexity reduction approach technique. app...

1 Parallel, multithreaded Java applications such as web servers, database servers, and scientific applications are becoming increasingly prevalent. Most of them have high object instantiation rates through the new bytecode that is implemented in a garbage collection subsystem typically. For aforementioned applications, traditional garbage collectors are often the bottleneck that limits program ...

We have measured the energy efficiency of different memory management strategies on a high performance pocket computer. We conducted our study by measuring the energy consumption of eight C programs with four different memory management strategies each. The memory management strategies are: no deallocation, explicit deallocation, conservative mark-and-sweep garbage collection, and conservative ...
