Micro electromechanical systems (MEMS) based capacitive pressure sensor for ultral-low pressure using graphene has been proposed. The characteristics of sensor such as membrane displacement, capacitance and sensitivity of sensor with external pressure effect are simulated and analyzed using Comsol Multiphysics software. The obtained results show that the MEMS capacitive pressure sensor using 3, 5, 7-layer graphene exhibits the sensitivity of 230.8 aF/Pa, 174.4 aF/Pa and 144.4 aF/Pa, respectively.

The work proposes a synthesis method of capacitive fractional-order impedance element which is composed of homogenous distributed resistive-capacitive (RC) structures (lines). The method employs genetic algorithm and searches for optimal connection schemes and parameters of the partial RC structures. The synthesis algorithm is described in detail including the coding of the properties of the structures for the purpose of the genetic algorithm. The user interface of the design tool is introduced and the input and output parameters of the synthesis are explained.

Capacitive deionization (CDI) is an electrochemical water treatment process that holds the promise of not only being a commercially viable alternative for treating water but for saving energy as well. Carbon aerogel electrodes for CDI process with high specific surface area (779.04 m2 /g) and nanopore (2-90 nm) have been prepared via pyrolyzing RF organic aerogel at 800oC in nitrogen atmosphere.

This paper investigates local search approach for solving the min-max capacitated vehicle routing problem with different neighborhood structures. We also propose a combined function instead of the objective function itself for controlling the local search. Experimental results on different datasets show the efficiency of our proposed algorithms compared to previous techniques.

The optimal solution to enhanced flow problem may be obtained from the optimal solution to the related transportation problem. An algorithm is presented to solve a capacitated indefinite quadratic transportation problem with enhanced flow. Numerical illustrations are also included in support of the theory. Computational software GAMS is also used.

This paper discusses a paradox in fixed charge capacitated transportation problem where the objective function is the sum of two linear fractional functions consisting of variables costs and fixed charges respectively. A paradox arises when the transportation problem admits of an objective function value which is lower than the optimal objective function value, by transporting larger quantities of goods over the same route.

This paper presents the design, fabrication and operation of a highly symmetrical twoaxis capacitive sensor. The proposed sensor consists of five electrodes, including of an excitation electrode and two pairs of sensing electrodes with exactly the same dimensions, arranged at identified symmetrically locations on a 3D printed hollow sphere, which containing dielectric medium formed by the partly filled oil and the remaining air.

In this study, capacitance and conductance methods were used to investigate the charge traps at a HfO2/(100)InGaAs interface with an atomic layer deposition HfO2 layer doped with Al2O3 by co-deposition technique. The effect of Al doping on the quality of the HfO2/In0.53Ga0.47As interface will be evaluated. The density of interface traps (Dit) near In0.53Ga0.47As midgap is close to 2×1012 cm−2eV−1.

In this paper, capacitated MCLP and dynamic MCLP are integrated with each other and dynamic capacity constraint is considered for facilities. Since MCLP is NP-hard and commercial software packages are unable to solve such problems in a rational time, Genetic algorithm (GA) and bee algorithm are proposed to solve this problem.
