Chapter 1 1. INTRODUCTION Artificial Neural Networks are being touted as the wave of the future in computing. They are indeed self learning mechanisms which don ’t require the traditional skills of a programmer. But unfortunately‚ misconceptions have arisen. Writers have hyped that these neuron-inspired processors can do almost anything. Fig. 1.1 Neural Network These exaggerations have created disappointments for some potential users who

C H A P T E R 3 RESISTIVE NETWORK ANALYSIS hapter 3 illustrates the fundamental techniques for the analysis of resistive circuits. The chapter begins with the definition of network variables and of network analysis problems. Next‚ the two most widely applied methods— node analysis and mesh analysis—are introduced. These are the most generally applicable circuit solution techniques used to derive the equations of all electric circuits; their application to resistive circuits

INTRODUCTION A network is a group of people who exchange information and contacts for professional or social purposes. To broaden our knowledge and improve our chances of having a better life‚ we engage in a system that can help us or connect us to people or things that will or can help us realise our goals. That system is a personal network. It starts with defining what your goal is then from there‚ you start looking for peripherals or perspectives that can connect you or move you towards that goal

COMMUNICATION AND COMPUTER NETWORK 4.1 INTRODUCTION Today computer is available in many offices and homes and therefore there is a need to share data and programs among various computers with the advancement of data communication facilities. The communication between computers has increased and it thus it has extended the power of computer beyond the computer room. Now a user sitting at one place can communicate computers of any remote sites through communication channel. The aim of this chapter

understood to be the current in branch k attached to node m. The currents used in this expression are understood to be the currents that would be measured in the branches attached to the node‚ and their values include a magnitude and an algebraic sign. If the measurement convention is oriented for the case where currents are entering the node‚ then the actual current in a branch has a positive or negative sign‚ depending on whether the current is truly flowing toward the node in question.
