Modelling with differential equations is an effective tool to provide methodical and quantitative solutions to real-world phenomena including investigating measurable features, consolidation and processing of data, and to design and develop complex engineering systems. This book describes differential equations correlation with qualitative and quantitative analysis, and mathematical modelling in the engineering and applied sciences. Given equations are explained from multidimensional characterizations with MATLAB codes. Features: Addresses differential equation-based approaches to solve varied engineering problems. Discusses derivation and solution of major equations of engineering and applied science. Reviews qualitative and quantitative (numerical) analysis and mathematical modelling. Includes mathematical models of the discussed problems. Discusses MATLAB code and online materials related to the differential equations. This book is aimed at researchers, graduate students in electrical and electronics engineering, control systems, electron devices society, applied physics, engineering design.

This book teaches basic and advanced concepts, new methodologies and recent developments in VLSI technology with a focus on low power design. It provides insight on how to use Tanner Spice, Cadence tools, Xilinx tools, VHDL programming and Synopsis to design simple and complex circuits using latest state-of-the art technologies. Emphasis is placed on fundamental transistor circuit-level design concepts.

A torrential flood can sink and wash away homes as well as damage various other properties such as electrical goods, vehicles and the like. This is a loss for residents. The worst effect of floods is on one's health. Floods often result in a loss of life especially in low-lying areas and along river banks. Floods damage public property such as roads, buildings, and telephone and electrical infrastructures. The situation becomes worse near a dam or the barrage where the river water is stored for the multipurpose use. During the monsoon time the water level of the dam increases and when it overflows the dam it causes flood thus destroys many lives and also properties. Although there is a provision for the alert but the alert is made by observing the water level at the dam manually and then sending the alarm to the people. Under this circumstance, if we make some autonomous system which will measure the water level and also transmit the data to specific location, we can save a lot of lives as well as properties. So the aim of my project is "PIC 16F877A based embedded water level sensor for an automatic flood alarming system.
