Hypertext is an emerging technology that, if selected and used properly, can add tremendous efficiency and power to an organization's computing environment, especially its online documentation systems. This article describes the design, selection, and implementation considerations involved in developing a hypertext system. It is intended to help IS managers better evaluate hypertext's applicati...

PURPOSE The purpose of this study was to compare the optical performance of diffractive multifocal intraocular lenses (DMIOLs) with visible (VIS) illumination with that of near infrared (NIR) illumination, the latter being used to test pseudophakic eyes in clinical aberrometers and double-pass systems. METHODS Two DMIOLs of different design (Tecnis +2.75 D ZKB00 and AcrySof +2.5 D SV25T0) wer...

The general-purpose trigger and readout board (TRBv2) with on-board DAQ functionality and extensibility through add on cards has been developed and was used successfully in two beamtimes in the year 2007. The functionality of the TRBv2, already roughly outlined in [1], is described in [2]. Several add on modules, which enhance the functionality/connectivity of the TRBv2, have been developed and...

This paper presents a low-power co-processor designed for power-efficient, real-time mono and stereo Weighted Overlap-Add (WOLA) filterbank processing. The filterbank easily interfaces to general-purpose DSP processors as a co-processor and provides high fidelity filterbank processing with low group delay for a wide range of applications. The co-processor architecture is very flexible and gener...

Cooperative routing in Wireless Sensor Networks can improve performance in these types of networks. In our work, we propose a routing algorithm called Location-based Cooperative Routing with Sensor Power-upper-limit for Wireless Sensor Networks. The algorithm is based on the principle of minimum link power and aims to take advantage of nodes cooperation to make the link work well in Wireless Se...

Three modular multiplication algorithms are described and compared: the so-called Multiply and Reduce, the Shift and Add, and finally, the Montgomery product. An estimation of the cost of their combinational implementation using Xilinx FPGAs family is calculated. Practical results in term of area, delay, and power for both combinational and completely sequential implementations are presented.

Multipliers and adders are the basic circuits required for implementing any Arithmetic and logic functions in VLSI. Many of the real-time applications like the arithmetic operations in Microprocessor, the filter designing in Signal processing require the multipliers. As the multipliers play a major role in the VLSI designing the power consumption related to them is a parameter to be thought of....

We investigated small-scale hydraulic power actuation systems using a system level analysis, where smallscale refers to systems generating 10 to 100 Watts output power, to determine whether the high power density advantage of hydraulics holds at small sizes. Hydraulic actuator system power density was analyzed with simple physics models and compared to an equivalent electromechanical system com...
