reconfigurable instruction set processors allow customization for an application domain by extending the core instruction set architecture. extracting appropriate custom instructions is an important phase for implementing an application on a reconfigurable instruction set processor. a custom instruction (ci) is usually extracted from critical portions of applications and implemented on a reconf...

All the previous Kernighan-Lin (KL) based circuit partitioning algorithms employ the locking mechanism, which enforces each cell to be moved exactly once per pass. In this paper, we propose two novel approaches for multiway circuit partitioning to overcome this limitation. The proposed approaches are based on our claim that the performance of a KL{based partitioning algorithm gets better by all...

A rapid overview of the Three Phase Partitioning (TPP) system as an efficient non-chromatographic tool is given. This elegant non-chromatographic tool is able to purify numerous proteins and especially proteases in a one step protocol. TPP is able to do not only purify proteins, but also concentrate them into one of the phases and enhance their proteolytic activity. The application of TPP for t...

The partitioning of reactive nitrogen compounds between the gas and the aerosol phase, as observed during the MINOS (Mediterranean INtensive Oxidant Study) campaign in Crete, Greece, in July and August 2001, has been studied with three thermodynamic gas-aerosol equilibrium models (EQMs) of different chemical complexity: ISORROPIA, which is limited to the ammonium-sulfatenitrate-sodium-chloride-...

This work reports a novel approach where three phase partitioning (TPP) was combined with microwave for extraction of mangiferin from leaves of Mangifera indica. Soxhlet extraction was used as reference method, which yielded 57 mg/g in 5 h. Under optimal conditions such as microwave irradiation time 5 min, ammonium sulphate concentration 40% w/v, power 272 W, solute to solvent ratio 1:20, slurr...

Three-phase partitioning (TPP) is carried out by mixing ammonium sulfate and t-butanol to obtain organic phase, interfacial precipitate and aqueous phase. It is shown that TPP of an 8 M urea/100 mM dithiothreitol-denatured xylanase preparation resulted in simultaneous renaturation and purification. This integrated novel approach gave recovery of 93% enzyme activity with 21-fold purification. Th...

We show a two-phase approach for minimizing various communication-cost metrics in fine-grain partitioning of sparse matrices for parallel processing. In the first phase, we obtain a partitioning with the existing tools on the matrix to determine computational loads of the processor. In the second phase, we try to minimize the communicationcost metrics. For this purpose, we develop communication...
