23-million-euro investment by China and Germany for construction of a power plant in Mazandaran.

That the global energy system is not sustainable is clearly demonstrated by increasingly scarce resources. frequently unstable energy supplies. and climate change.

The Teager-Kaiser energy operator (TKO) belongs to a class of autocorrelators and their linear combination that can track the instantaneous energy of a nonstationary sinusoidal signal source. TKO-based monocomponent AM-FM demodulation algorithms work under the basic assumption that the operator outputs are always positive. In the absence of noise. this …

A new MFM-BDRM is proposed. solving the contradictory problem of the electromagnetic performance and the mechanical strength of MFM rotor in the traditional MFMBDRM. The proposed one has advantages of highly sinusoidal back EMF and low torque ripple. The maximum torque can be obtained when the optimal span ratio is …

By considering real power forecast of DGs. reactive power ranges are better determined and used for day-ahead reactive power dispatch of distribution networks. In particular. errors of real power forecast have been used to estimate probability distribution of reactive power outputs available for achieving optimal power flow and reducing network …

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 …
