TL;DR: The present work explains in details how SPICE can be used for simulation of electronic circuits in nanotechnology regime.
Abstract: Very large scale integration (VLSI) circuit homes a very huge number of components on the chip. Simulation studies along with analytical analysis are needed to design and validate the functionality of the VLSI circuits, before finally fabricating them. For this purpose detailed case studies of SPICE simulations of the circuits are carried out. Therefore, the present work explains in details how SPICE can be used for simulation of electronic circuits in nanotechnology regime.

TL;DR: A one-circuit and one-step procedure for evaluation of the two parameters of the Thevenin equivalent circuit is propsed and unlike Murti's Method, it can handle the controlled sources also.
Abstract: A one-circuit and one-step procedure for evaluation of the two parameters of the Thevenin equivalent circuit is propsed. Unlike Murti's Method, it can handle the controlled sources also. The procedure is illustrated with two examples.

TL;DR: There are many different ways of solving an ordinary linear second order differential equation with constant coefficients as discussed by the authors, and a comprehensive survey of these methods is presented in this article, along with the essential steps in each method and relevant references.
Abstract: There are many different ways of solving an ordinary linear second order differential equation with constant coefficients. Some of them arc available in text books while some others are scattered in journal publications. A comprehensive survey of these methods is presented in this article, along with the essential steps in each method and the relevant references.“As many faiths, as many ways” - Shri Ramakrishna Paramhansa
TL;DR: The selection and control of multiple robot arms for industrial applications that require more than a single robot arm to achieve the task are presented and a control and drive circuit is proposed for this purpose.
Abstract: This paper presents the selection and control of multiple robot arms for industrial applications that require more than a single robot arm to achieve the task. We have used two robot arms with 6 Degrees of Freedom each to demonstrate the control for a ‘pick and place’ industrial application. The control of multiple robot arms in conjunction can be implemented in certain applications to effectively reduce the ‘mission time’. We have proposed a control and drive circuit for this purpose. The discrete control signals from the parallel port of a PC are used to control the robot arms and the control logic is implemented using ‘C’ programming language.
TL;DR: This paper reviews mixed-mode signal processing architectures for computation of discrete signal processing transforms and the Resistance-String and Capacitor-Switched architectures utilize a resistance string and capacitor array along with switched-capacitor circuits for their implementation.
Abstract: This paper reviews mixed-mode signal processing architectures for computation of discrete signal processing transforms. The Resistance-String and Capacitor-Switched architectures utilize a resistance string and capacitor array, respectively, along with switched-capacitor circuits for their implementation. Switched-Current architecture utilizes switched-current circuits for implementing the processing elements. Programmable block matrix transform architecture uses floating gate circuits for computations. All these mixed-mode architectures make use of different technology and circuits to compute the transforms in real time.
