In this paper, a high performance current-mode instrumentation amplifier has been proposed for low noise, low power, high CMRR and adjustable gain with an external resistor for various biomedical signal processing. The portable biomedical instrumentation has become an important part of diagnostic and treatment instrumentation, including telemedicine applications. The low voltage and low-power d...

This paper presents a fully-integrated RF transceiver operating from 860 to 930 MHz. The device parameters are compliant to the IEEE 802.15.4 standard. The analog portion of the chip contains a direct-conversion receiver, a fractional-N PLL, a direct-conversion transmitter and a TR-switch. Digital baseband signal processing as well as MAC support are also implemented on the same chip. Only mini...

this paper presents an indirect adaptive system based on neuro-fuzzy approximators for the speed control of induction motors. the uncertainty including parametric variations, the external load disturbance and unmodeled dynamics is estimated and compensated by designing neuro-fuzzy systems. the contribution of this paper is presenting a stability analysis for neuro-fuzzy speed control of inducti...

Recently, indoor air quality has attracted the attention of policymakers and researchers as a critical issue like that of external air pollution. Indoor air quality is more important as people spend time longer indoors than outdoors. Indoor environments are closed compared to external environments providing less opportunity for the pollutants to dilute. The emissions contain many substances tha...

Technologically assistive devices are increasingly playing more important roles in the lives of persons with disabilities, with one of the more promising considerations being a combination of the functions of computer software and hardware. However, using a conventional keyboard for Internet access is prohibitive for persons whose hand coordination and dexterity are impaired by ailments such as...

This paper describes the development of a non-visual memory game based on the classic game ̳SimonTM‘, where users are presented with a sequence of stimuli, which they need to replicate in the same order to progress to the next level. Information is presented using a combination of speech, nonspeech audio and/or haptic cues, designed to aid blind users who are often excluded from mainstream gami...

awardness about structure of production technology and its characteristics is a usefull tool for planning in agricultural sector. in this regard, this study aims to determine some effective parameters of structure of production technology in rain fed barley production. before estimating these parameters, we examine the aggregation consistency condition for barley fields using the mean scaling t...
