Energy harvesters serve as continuous and long-lasting sources of energy that can be integrated into wearable implantable sensors biomedical devices. This review paper presents the current progress, challenges, advantages, disadvantages future trends which harvest from various human body. The most used types are chemical; thermal biomechanical each group is represented by several nano-generator...

machine modeling is a popular technique for developing portable compilers. A compiler can be quickly realized by translating the abstract machine operations to target machine operations. The problem with these compilers is that they trade execution efficiency for portability. Typically the code emitted by these compilers runs two to three times slower than the code generated by compilers that e...

The problem of test generation belongs to the class of NP-complete problems and it is becoming more and more di cult as the complexity of VLSI circuits increases, and as long as execution times pose an additional problem. Parallel implementations can potentially provide signi cant speedups while retaining good quality results. In this paper, we present three parallel genetic algorithms for simu...

The utility of expert system generators has been widely recognized in many applications. Several generators based on concept of the paradigm object, have been recently proposed. The generator of oriented object expert system (GSEOO) offers languages that are often complex and difficult to use. We propose in this paper an extension of the expert system generator, JESS, which permits a friendly u...

All-polymer solar cells have shown great potential as flexible and portable power generators. These devices should offer good mechanical endurance with high power-conversion efficiency for viability in commercial applications. In this work, we develop highly efficient and mechanically robust all-polymer solar cells that are based on the PBDTTTPD polymer donor and the P(NDI2HD-T) polymer accepto...

Multiple independent streams of random numbers are often required in simulation studies, for instance, to facilitate synchronization for variance-reduction purposes, and for making independent replications. A portable set of software utilities is described for uniform randomnumber generation. It provides for multiple generators (streams) running simultaneously, and each generator (stream) has i...

This report is a discussion, evaluation and comparison of potential sources of electrical power for small mobile systems. Power sources are an inevitable challenge in the design of portable and small mobile systems, especially robotic systems. Power systems cannot be an afterthought and, if left to final design stages, can result in severe and adverse effects on the system, such as excess weigh...

A Reidemeister-Schreier program which yields a presentation of a subgroup H of finite index in a finitely presented group G is described in [3J. The program has two stages; first, Schreier generators and Reidemeister relators for H are computed, then the resulting presentation is simplified by eliminating redundant generators and by using a substring searching technique. The Tietze transformati...
