A higher-order sliding approach to control a bioreactor model is proposed by non-commensurate fractional equations. The model outputs by the help of a controller reached the desired values and track them. According to existing conditions and chattering reduction, a high-order sliding mode has been chosen to design the controller. The purpose of the paper is […]
Since two-wheeled and self-balancing robot has a complicated and non-linear structure, its model has some uncertainties. These uncertainties cause that the system has an incorrect solution if while using the classic methods for controlling of it. In this paper, a new method based on interval analysis is proposed for modeling the optimal control of the […]
Recently, power system restructuring, demand response (DR) program and using of distributed generation (DG) are important issues to enhance reliability, power flow continuity and power quality for costumers. In this paper, scheduling of distributed networks with DR program for a 24-hours optimization problem is modelled. The DR program is based on load side participation and […]

Photovoltaic (PV) panels are rely on environmental condition such as irradiation or temperature so, they are required to an interface boost converter. Non-isolated DC-DC boost converters have lower volume, lower costs and lower power dissipation compare to isolated converters. Therefore, a non-isolated boost converter is used in this paper. The proposed structure is controlled by […]
We have presented the investigation on the slab of photonic crystals that was made of a honeycomb lattice of silicon embedded in free space. For the simulation of this structure was used the two-dimensional finite-difference time-domain (FDTD) method. This arrangement was shown that with suitable choice of frequency can have negative refraction with an effect […]
FinFETs are the emerging 3D-transistor structures due to strong electrostatic control of active channel by gate from more than one side which was not possible in conventional transistor. FinFET structures with rectangular and trapezoidal shape have been excessively analyzed in literature. In this work, FinFET with Broadwell-Y shape proposed by Intel, has been designed and […]
by development of using software of Enterprise Content Management (ECM), necessity of improving electronic Correspondence of inter-enterprise is felt more than before in order to enterprise cooperation. Despite existence of some bases for enterprise content management such as ECE protocol still there are some problems such as user intervention, delay, consumption of paper, parallelism, impossibility […]
This paper presents a simulation of the dynamic voltage stability in power system. In application of modern power system, dynamic assessment of voltage stability is known as basic concept. In order to study dynamic voltage stability in a power system, different dynamic boundaries are defined such as, Hopf bifurcation (HB) boundary. HB point is an […]
Side-channel attacks are considered to be the most important problems of modern digital security systems.

The semiconductor circuits dissipate energy in the form of binary digits. This dissipation of energy is in the form of power consumption. ALU is complex circuit and is one of many components within CPU. It performs mathematical and bitwise operations. This paper proposes a new low power 8 bit ALU digital circuit for nano scale […]
Diabetes is the most costly gland disease in the world. Given the high rates of diabetic people, the necessity of reducing the costs of early re-hospitalization and increasing re-admissions within 30 days after discharge have drawn the attention of researchers and other health sector authorities to find ways to reduce potential and preventable hospital re-admissions.
