The aim of the present research was to prepare and evaluate a gastroretentive drug delivery system for metformin HCl, using synthetic and semi-synthetic polymers. The floating approach was applied for preparing gastroretentive tablets (GRT) and these tablets were manufactured by the direct compression method. The drug delivery system comprises of synthetic and semi-synthetic polymers such as po...

High speed execution of arithmetic operations and high degree of precision in real time system are of major concern in any digital signal processing (DSP). Speed of DSP depends on speed of multiplier and algorithm used. In this paper we propose Residue Number System method for fast “carry free” floating point arithmetic operations. Floating Point RNS units have obvious advantages over tradition...

A new homogeneous computer architecture developed by FPS combines two fundamental techniques for high-speed computing: parallelism based on the binary n-cube interconnect, and pipelined vector arithmetic. The design makes extensive use of VLSI technology, resulting in a processing node that can be economically replicated. Processor nodes incorporate high-speed communications and control, vector...

Cell culture is one of the most important methods of research in molecular and cellular biology, and various culture systems have been developed, including two-dimensional (2D), three-dimensional (3D) and floating culture systems. In the present study, we examined morphological changes and different expression patterns of cytoskeletal proteins in three different types of nervous system tumor ce...

Recent developments in European recirculating aquaculture systems suggest expanding potential for this extremely water-efficient technique. However, the technology still faces challenges due to concerns over economic efficiency and system stability—both essential in minimizing the risk of financially and environmentally expensive failures. One key factor in maintaining stable production conditi...

Fingerprint image enhancement is an important step in a fingerprint verification system. The enhancement process, however, are often not applied to mobile embedded devices in which floating-point processing units (FPU) are absent. Earlier Hong and Jain reported a fingerprint enhancement algorithm based on the Gabor Filter. This algorithm and its derivatives have been proved to be quite effectiv...
