The operational transconductance amplifier (OTA) is a basic building block used in many analogue and mixed-mode circuits such as analogue-to-digital (A D) converters and switched-capacitor filters that require fast settling and precise amplifiers [1]. Recently. the folded cascode (FC) amplifier has gained preference over the telescopic owing to the low …

As the supply voltage of a circuit decreases. noise immunity becomes more important to guarantee signal integrity. This paper presents a method of improving noise immunity applicable to subthreshold circuits. The traditional method for immunity enhancement is to use a Schmitt trigger. which requires an additional current path to adjust …

In a nutshell. the paper advocates for applying IoT architecture in providing smarter. connected and personalized healthcare solutions in smart homes. Their requirements for such healthcare services are analyzed and are translated into a functional architecture. Its components are mapped onto physical infrastructure. The components are described and their novel …

A hierarchical control approach was proposed for optimal operation of greenhouses in the context of smart grids. which includes novel mathematical models for the optimal operation scheduling of greenhouse’ electricity. gas. and heat systems. Thus. optimization models were formulated to optimally operate supplementary lighting. CO2 generation. air circulation and ventilation. …

The paper presents the mathematical model development for simulation of common faults in a currentsource PWM inverter. This approach embeds into a single simulation module both the unfaulty or faulty states of this type of power electronic converter. The proposed model has been validated then via computer simulations. The introduced …

Comparison of three major routing protocols in a MANET of sensor network shows that in terms of end to end delay. network load and throughput AODV performs better than other two. In other sense. reactive routing protocols performs better than proactive routing protocols. As. AODV routing protocol is suited for …

Survey of the literature allows concluding that each power system has to develop its own individual strategy for power transformer risk assessment and development of risk matrix is a common global practice.To determine numerical values of the indicator based on oil analysis combined approach of binary and fuzzy logic proved …

The paper has investigated the derivation. features and characteristics of passive sentences in JA. After exposing the structure of passivization in JA to the claim of the Minimalist Program. it has been found that a lot of its aspects can be straightforwardly accounted for in the light of feature-checking and …

This paper addresses the design and implementation of a high-frequency full bridge bidirectional isolated dc–dc converter intended for high-power applications. The proposed BIDC system. consists of two symmetrical single phase full bridge VSCs. two dc capacitors. auxilary reactors and an high frequency (HF) transformer that provides the required galvanic isolation. …

In this paper. a real-time fusion system for human action recognition has been developed that uses data from two differing modality sensors: vision depth and inertial. The system merges the probability outputs of the features from these two differing modality sensors in real-time via a decisionbased fusion method involving collaborative …
