— Profiling tools are computer-aided design (CAD) tools that help in determining the computationally intensive portions in software. Embedded systems consist of hardware and software components that execute concurrently and efficiently to execute a specific task or application. Profiling tools are used by embedded system designers to choose computationally(More)
— A soft-core processor is a hardware description language (HDL) model of a specific processor (CPU) that can be customized for a given application and synthesized for an ASIC or FPGA target. In many applications, soft-core processors provide several advantages over custom designed processors such as reduced cost, flexibility, platform independence and(More)
Multi-FPGA systems (MFSs) are used as custom computing machines, logic emulators and rapid prototyping vehicles. A key aspect of these systems is their programmable routing architecture which is the manner in which wires, FPGAs and Field-Programmable Interconnect Devices (FPIDs) are connected. Several routing architectures for MFSs have been proposed(More)
This article presents the design and implementation of modular customizable event-driven architecture with parallel execution capability for the first time with wireless sensor nodes using stand alone FPGA. This customizable event-driven architecture is based on modular generic event dispatchers and autonomous event handlers, which will help WSN application(More)
Trapeziectomy, by itself or combined with ligament reconstruction/interposition arthroplasty, is commonly performed for advanced trapezial-metacarpal arthritis. Several methods and materials, both autogenous and artificial, are commonly used for ligament reconstruction and interposition arthroplasty. Harvesting autologous tendons adds to operative time and(More)

The interaction of ATP with the phosphoenzyme of Na(+),K(+)-ATPase from pig kidney, rabbit kidney, and shark rectal gland was investigated using the voltage-sensitive fluorescent probe RH421. In each case, ATP concentrations >or=100 microM caused a drop in fluorescence intensity, which, because RH421 is sensitive to the formation of enzyme in the E2P state,(More)
A new radius-adjusted approach for blind adaptive equalization for quadrature amplitude modulation (QAM) signals is introduced. Static circular contours are defined around an estimated symbol point in a QAM signal constellation, which creates regions that can be mapped to adaptation phases. The equalizer tap update consists of a linearly weighted sum of(More)
This paper proposes two new hybrid blind algorithms based on a new radius-adjusted approach for QAM signal constellations and presents a comprehensive survey of hybrid methods for blind adaptive equalization. The proposed hybrid blind algorithms define static circular regions around symbol points that correspond to a specific weight-ing factor and stepsize,(More)
