The motive of this work is to design on chip efficient low power techniques using VHDL coding. Serial links in network on chip provide many advantages in terms of crosstalk, skew, area cost, clock synchronization, and wiring difficulty when compared to multi-bit parallel data transmission. The proposed a novel coding technique reduces the number of transitions and hence reduces transmission ene...

OBJECTIVE Preliminary assessment of the efficacy and safety of the low speed rotational angioplasty catheter system (ROTACS). DESIGN Open prospective trial. SETTING Department of cardiology in a teaching hospital. PATIENTS Eleven patients (10 with chronic stable angina and one with acute coronary occlusion after conventional angioplasty) in whom a coronary angiogram showed occlusion or cr...

A set of companion documents describe an architecture for providing integrated services over low-bitrate links, such as modem lines, ISDN B-channels, and sub-T1 links [1, 2, 3, 4]. The main components of the architecture are: a set of real-time encapsulation formats for asynchronous and synchronous low-bitrate links, a header compression architecture optimized for real-time flows, elements of n...

most of the methods that have been proposed for speed estimation of induction machines require the rotor and the stator resistance to change in the normal operating range. on the other hand, estimation of the rotor resistance requires rotor speed. in this paper, after studying conditions for simultaneous estimation of rotor speed and rotor resistance, a method for simultaneous estimation of rot...

The goal of the project was to design a low-cost digital oscilloscope targeted at students, hobbyists, and researchers. The requirements of the oscilloscope were three-fold: 1) cost less than $100, 2) capture frequencies over the range 20Hz–20kHz, and 3) constructable with a basic soldering iron and limited soldering skills. The primary parts of the oscilloscope are two Atmel ATmega644 microcon...

This paper describes a new design of low power 3-2 compressor circuit for high speed multipliers. Power consumption of proposed 3-2 compressor circuit varies from 0.355 nW to 1.6964 nW and delay varies from 2.0390 ns to 2.0224 ns. Further, power delay product of proposed circuit varies from 7.23×10 -18 (J) to 34.30×10 -18 (J) with varying supply voltage from 1.8V to 3.3V. The proposed compresso...

A set of experiments on speed control realised with LEGO elements is presented. Despite their simplicity and low cost, the setups allow to address several interesting control problems. To witness this statement, part of the activity for the course titled ‘Engineering and Technology of Control Systems’ is described. The characteristics of the proposed experiments make them very suitable both for...

Nowadays, vehicle safety is constantly increasing thanks to the improvement of vehicle passive and active safety. However, on a daily usage of the car, traffic jams remains a problem. With limited space for road infrastructure, automation of the driving task on specific situation seems to be a possible solution. The French project ABV, which stands for low speed automation, tries to demonstrate...

Ubiquitous computing is a next generation information technology where computers and communications will be scaled further, merged together, and materialized in consumer applications. Computers will be invisible behind broadband networks as servers, while terminals will come closer to us as wearable/implantable devices, more friendly devices with sophisticated human-computer-interactions. IC ch...

We consider the steady-state equations for a compressible uid. For low-speed ow, the system is sti because the ratio of the convective speed to the speed of sound is quite small. To overcome this di culty, we alter the time evolution of the equations but retain the same steady-state analytic equations. To achieve high numerical resolution, we also alter the arti cial viscosity of the numerical ...
