The Spatial reuse Time Division Multiple Access (STDMA) ad hoc networks take advantage of the electromagnetic spectrum reuse to increase the global capacity of the network. The schedule creation takes into account different variables. One of them, the Signal-Interference plus Noise Ratio (SINR) generates that the geographical distribution of nodes influences a lot the behavior of the network. T...

Abstract: Electromagnetic interference (EMI) has a negative effect upon the performance of circuit communication systems. The present study considers the case of EMI and it is shown that the harmonic noise increases with an increasing interference amplitude and frequency. When electromagnetic interference takes place with the input pins of 555 Timer using as an Monostable Multivibrator it can c...

Sensing intrinsic cardiac electrical activity is essential for the function of pacemakers and implantable cardioverter defibrillators (ICDs). Examples of undesired triggering or inhibition of pacemaker output by extraneous signals were identified early after the introduction of noncompetitive, “demand” pacemakers. Hermetic shielding in metal cases, filtering, and interference rejection circuits...

Our modern society depends on the functioning and interplay of a wealth of infrastructures. Practically all of these infrastructures are in some form or another, dependent on electrical and electronic systems. The majority of modern infrastructure is dependent on electric power and controlled by Supervisory Control and Data Acquisition (SCADA) systems. Electronic systems are sensitive to electr...

Electromagnetic interference disturbs the working of electronic devices and affects surroundings human health. Consequently, research has led to development radiation-protection materials. Inherently conducting polymers have been found be suitable for electromagnetic (EMI) shielding owing their fine electrical conductivity properties. Moreover, nanoparticle-reinforced conjugated used form effic...
