The paper describes a novel hashing method suitable for lookup functions. Traditional methods are either of lower hash quality or inferior performance. In this paper, we show how to compute a high-quality hash digest at extremely high performance on Intel ® processors using the crc32 instruction. Our method also generates multiple 32-bit hashes of an input data buffer, which have low correlatio...

A method is proposed for automatic instrumentation of enzyme activity determinations which involve spectrophotometric measurements. The procedure utilizes a kinetic method to produce one instrumental reading that is proportional to enzyme concentration. The single spectrophotometric reading can be processed by analog or digital computation, using the known absorptivity constant of the reactant ...

Using the parametrizations of Kubert, we show how to produce in nite families of elliptic curves which have prescribed nontrivial torsion over Q and rank at least one. These curves can be used to speed up the ECM factorization algorithm of Lenstra. We also brie y discuss curves with complex multiplication in this context.

This paper presents a method for service-component testing and a suitable CORBA test architecture. This test environment allows the service validation from its components and is a close step towards the execution of the obtained tests on a CORBA environment. Two aspects are relevant: the test of components and the test architecture. The testing method for components is new: it is based on the g...

Finding and recommendation of suitable persons based on their characteristics in social or collaboration networks is still a big challenge. The purpose of this paper is to discover and recommend suitable persons or whole community within a developers’ network. The experiments were realized on the data collection of specialized web portal used for collaboration of developers Codeplex.com. Users ...

PCR has become one of the most popular techniques in functional genomics. Projects in both forward and reverse genetics routinely require PCR amplification of thousands of samples. Processing samples to extract DNA of sufficient purity for PCR is often a limiting step. We have developed a simple 96-well plate-based high-throughput DNA extraction method that is applicable to many plant species. ...

introduction: musculoskeletal disorders are the major causes of occupational diseases in the work places and they are the most important cause of disability and absenteeism. for the prevention of these disorders and improvement of working, it is necessary to use ergonomics assessment techniques. this study aimed to assess ergonomic risk factors for musculoskeletal disorders in construction work...

Increasing research activity on cellulose nanofibril-based materials provides great opportunities for novel, scalable manufacturing approaches. Cellulose nanofibrils (CNFs) are typically processed as aqueous suspensions because of their hydrophilic nature. One of the major manufacturing challenges is to obtain dry CNFs while maintaining their nano-scale dimensions. Four methods were examined to...

This paper deals with a problem of road tracking and vehicle positioning based on sequential images captured by a vehicle mounted monocular colour camera. The paper presents a new region‐based road tracking method, which is suitable for both structured and unstructured roads. The proposed method is based on our original road segmentation algorithm and estimates road model paramet...

conclusion according to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. we resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. the complication rate is very low. the us-assisted percutaneous liver biopsy should be used for all cases. results a total of 1018 patients we...
