Recent interest in persistent memory (PM) has stirred development of index structures that are efficient in PM. Recent such developments have all focused on variations of the B-tree. In this paper, we show that the radix tree, which is another less popular indexing structure, can be more appropriate as an efficient PM indexing structure. This is because the radix tree structure is determined by...

In this paper a Split Radix FFT without the use of multiplier is designed. All the complex multiplications are done by using Distributed Arithmetic (DA) technique. For faster calculation parallel prefix adder is used. Basically high radix algorithms are developed for efficient calculation of FFT. These algorithms reduces overall arithmetic operations in FFT, but increases the number of operatio...

In this paper we present alternate form of Radix-4/8 and split radix FFT’s based on DIF (decimation in frequency) version and discuss their implementation issues that further reduces the arithmetic complexity of power-of-two discrete Fourier Transform. This is achieved with circular shift operation on a subset of the output samples resulting from the decomposition in these FFT algorithms and a ...

This paper introduces a new, faster sorting algorithm (ARL – Adaptive Left Radix) that does in-place, non-stable sorting. Left Radix, often called MSD (Most Significant Digit) radix, is not new in itself, but the adaptive feature and the in-place sorting ability are new features. ARL does sorting with only internal moves in the array, and uses a dynamically defined radix for each pass. ALR is a...

Scutellaria Radix, a traditional Chinese medicine, studies on its main active ingredient are limited. In this study, the purpose was to investigate quality difference of Scutellariae Radix from different origins based chemical components and biological activities. The chromatographic fingerprints 33 were established using HPLC, antibacterial activities studied with microdilution method. Moreove...

This paper focus on the development of the fast Fourier transform (FFT), based on Decimation-In-Time (DIT) domain by using Mixed-Radix algorithm (Radix-4 and Radix-8).Fast Fourier transforms, popularly known as FFTs, have become an integral part of any type of digital communication system and a wide variety of approaches have been tried in order to optimize the algorithm for a variety of parame...

Currently there has been no effective treatment of diabetic encephalopathy. Radix Polygoni Multiflori, a famous traditional Chinese medicine, is widely used in antiaging treatment, especially in prevention and treatment of Alzheimer's diseases. In this study we tried to explore the effect of Radix Polygoni Multiflori on cognitive function among diabetic rats with demonstrated cognitive impairme...

A simple and reliable method of ultra-performance liquid chromatography with photodiode array detector (UPLC-PDA) was developed to control the quality of Radix Isatidis (dried root of Isatis indigotica) for chemical fingerprint analysis and quantitative analysis of eight bioactive constituents, including R,S-goitrin, progoitrin, epiprogoitrin, gluconapin, adenosine, uridine, guanosine, and hypo...

The speed of SRT-type dividers is mainly determined by the complexity of the quotient-digit selection , so that implementations are limited to low-radix stages. We present a scheme in which the quotient-digit is speculated and, when this speculation is incorrect , a rollback or a partial advance is performed. This results in a division operation with a shorter cycle time and a variable number o...
