the concept of comprehensive grobner bases was introduced by weispfenning. montes has proposed an efficient algorithm for computing these bases. but he has not explicitly used buchberger's criteria in his algorithm. in this paper we prove that we can apply these criteria on montes algorithm. we propose a modified version of montes algorithm and evaluate its performance via some examples.

Abstract The manufacturing capabilities available today for microchannels make it possible to produce in a comparatively easy, quick and cheap way several cross-sections, possibly allowing modifications of the macro-geometry. Another is smoothing corners polygona cross-sections: this eliminates low-gradient areas increases transport phenomena, i.e. frictional losses heat transfer. Several ways ...

This paper describes the works performed on a solution of packaging dedicated to 3D TR modules in the 2-20GHz frequency range. The proposed solution is based on a non hermetic architecture involving organic and BCB substrates. The studied key bricks relative to assembly, vertical interconnections, passives integration are described and results consecutive to electrical and environmental evaluat...

Criteria developed by the Remission in Schizophrenia Working Group (RSWG), based upon 8 core symptoms of PANSS, are generally used for evaluation of Remission. However, some concerns have arisen as regard to the ability of the RSWG criteria to detect truly remitted cases. This study aims to compare the severity criteria of remission defined by the RSWG (RSWG-cr) with more restrictive criteria, ...

Ultrafine-grained (UFG) Ti for improved mechanical performance as well as its surface modification enhancing biofunctions has attracted much attention in medical industries. Most of the studies on the surface etching of metallic biomaterials have focused on surface topography and wettability but not crystallographic orientation, i.e., texture, which influences the chemical as well as the physic...

Real-time pulse-contrast observation with a high dynamic range is a prerequisite to tackle the contrast challenge in ultra-high peak-power lasers. However, the commonly used delay-scanning cross-correlator (DSCC) can only provide the time-consumed measurements for repetitive lasers. Single-shot cross-correlator (SSCC) becomes essential in optimizing laser systems and exploring contrast mechanis...

Further performance improvement is necessary for resistive random access memory (RRAM) to realize its commercialization. In this work, a novel pulse operation method is proposed to improve the performance of RRAM based on Ti/HfO2/Pt structure. In the DC voltage sweep of the RRAM device, the SET transition is abrupt under positive bias. If current sweep with positive bias is utilized in SET proc...
