In the current paper, a neural network method to solve sixth-order differential equations and their boundary conditions has been presented. The idea this method incorporates is to integrate knowledge about the differential equation and its boundary conditions into neural networks and the training sets. Neural networks are being used incessantly to solve all(More)
—Multilevel gain-cell DRAMs are interesting to improve the area-efficiency of modern fault-tolerant systems-on-chip implemented in deep-submicron CMOS technologies. This paper addresses the problem of long access times in such multilevel gain-cell DRAMs, which are further aggravated by process parameter variations. A replica bit-line (BL) technique,(More)
This paper presents a memristor crossbar-basedpattern recognition circuit using perceptron learning rule. Theproposed circuit includes a memristor crossbar based trainingcircuit (TC)-module referred as 'synaptic network' and an operationalamplifier (Op-Amp) based neuron circuit. The TC-moduleis utilized to adjust synaptic weights according to applied(More)
This paper has emphasis on the novel sequence generation for the hardwired built in self test (BIST) of static random access memory (SRAM). It reduces the testing time of SRAM by generating all the pattern sequence in less time. BIST is a design technique that allows a circuit to test itself. Linear feedback shift register (LFSR) was used for the sequence(More)
Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policies at all levels, in order to create a healthy living environment. Differential equations are an effective way to analyze such situations. In this paper a system of linear equations with interconnecting pipes is considered for analyzing the(More)
In the course of this paper, the Optimal Homotopy Asymptotic Method (OHAM) introduced by Marica is applied to solve linear and nonlinear boundary value problems both for fourth-order integro-differential equations. The following analysis is accompanied by numerical examples whose results show that the Optimal Homotopy Asymptotic Method is highly accurate,(More)
Perovskite crystal structure is found in many ionic solids like CaTiO3, BaTiO3 and Lead Zirconate Titanates (PZT). In this structure off-center position of cations in oxygen octahedral causes polarization and produces direct and indirect piezoelectric responses in ceramic materials that are suitable for many ultrasonic applications. In the present study 9%(More)
An all new technique has been devised to solve non-linear Lane-Emden type equations. This novel technique is based on the Perturbation Iteration Algorithm. In this paper, a few examples are presented for the illustration of the power and wide usability of the proposed method. Moreover, a compare and contrast with the actual solution is provided. It has been(More)
