In this paper, novel methods for the evaluation of digital-filter stability are investigated. The based on phase analysis a complex function in characteristic equation digital filter. It allows evaluating when is not polynomial. operation these relies sampling unit circle plane and extracting quadrant value each sample. By calculating function-phase quadrants, regions immediate vicinity unstabl...

The stability control of nominal frequency and terminal voltage in an interconnected power system (IPS) is always a challenging task for researchers. load variation or any disturbance affects the active reactive demands, which badly influence normal working IPS. In order to maintain at rated values, controllers are installed generating stations keep these parameters within prescribed limits by ...

Computer-Aided diagnosis (CAD) is a widely used technique to detect and diagnose diseases like tumors, cancers, edemas, etc. Several critical retinal diabetic retinopathy (DR), hypertensive (HR), Macular degeneration, retinitis pigmentosa (RP) are mainly analyzed based on the observation of fundus images. The raw images inferior quality represent minor changes directly. To analyze in vasculatur...

The automatic upgradation of equalizer weights in channel equalization demands a low-complexity, highly accurate estimation recovery at the minimum possible time. low-complexity frequency domain improves mean square error (MMSE) process. Adding superiority particle swarm optimization (PSO) to coefficient selection process enhances MMSE. This work proposes frequency-domain along with modified PS...

Wireless sensor network (WSN) is a network, which has more numbers of sensors that are small in nature and self organised. The inbuilt battery system provided the nodes through can communicate do good operations among other available network. Lifetime most essential parameter needs to be maximised for WSN. This measure important conservation energy, adequate efficient performance networks. pape...

Abstract This paper presents a realization of fractional-order Band pass-filter (FOBF) based on the concepts fractional order inductors and capacitors. The FOBF is designed implemented using both simulation hardware approaches. proposed filter considered up to second or less with any real positive number. One cases when ? ? 1 ? ? 1. In case, calculate optimal parameters, modified Particle Swarm...
