in this paper we discuss on the fixed points of asymptotic contractions and boyd-wong type contractions in uniform spaces equipped with an e-distance. a new version ofkirk's fixed point theorem is given for asymptotic contractions and boyd-wong type contractions is investigated in uniform spaces.

The specifications analysis for an MVB (Multifunction Vehicle Bus) bus administrator showed that system-on-a-chip strategies should be adopted to cope with its great complexity. Particularly, a new hardware/software codesign methodology has been followed. Its main concept is that the MVB devices (the bus administrator itself and the less complex devices) constitute a “progressive family”. This ...

Myoelectric systems have received widespread use as controls of prosthetic devices for individuals with amputations or congenitally deficient upper limbs, (Parker and Scott, 1988). Many systems are now available commercially to control a single device (hand, elbow, wrist). These systems extract a control signal based on an estimate of the amplitude, (Dorcas and Scott, 1966), or on the rate of c...

We present a novel multifunction inverse biquad configuration based on current feedback operational amplifiers (CFOAs) and grounded passive elements. The proposed scheme can be used to realize inverse lowpass, inverse bandpass and inverse highpass filter functions. The relevant coefficients of the inverse filters are orthogonal adjustable by independent passive elements. All the passive element...

in this paper, we establish and prove the existence of best proximity points for multivalued cyclic $f$- contraction mappings in complete metric spaces. our results improve and extend various results in literature.

recently, choudhury and metiya [fixed points of weak contractions in cone metric spaces, nonlinear analysis 72 (2010) 1589-1593] proved some fixed point theorems for weak contractions in cone metric spaces. weak contractions are generalizations of the banach's contraction mapping, which have been studied by several authors. in this paper, we introduce the notion of $f$-weak contractions and als...

A new voltage-mode multifunction biquadratic filter using one differential difference current conveyor (DDCC), two grounded capacitors and three resistors is presented. The proposed circuit offers the following attractive advantages: realizing highpass, bandpass, lowpass and notch filter functions, simultaneously, from the same circuit configuration; employing grounded capacitors, which is idea...
