How a Hydroelectric power Station Works A hydroelectric power plant is a power station which produces electrical energy from the energy stored in water at certain heights, with the use of a turbine which is mechanically coupled to a generator.  So water is the primary source of energy in this type of power plant. In order to understand the conversion process, we shall chronologically study the different components and their role in the conversion process. The diagram below is a schematic diagram of a hydroelectric power plant. Layout of a hydroelectric power plant

Integration of Embedded Capacitors and Resistors in Multi-Layer Printed Circuit Board (PCB) Olome Baudouin Ekute  EEF714: PCB DESIGN AND FABRICATION Faculty of Engineering and Technology, University of Buea   I.                    I. Introduction The rapid development and high demands for more efficient, miniature electronic devices as well as increases reliability, have led researchers to develop new technologies in manufacturing printed circuit boards. In 1956 the first PCB was patent in the US which began with a single side on the PCB, then later the double sided PCB was developed forming connections between the components using the surface mount technology and the hole technology   [1] . Due to high functional demand, the multi-layer printed circuit board was developed with smaller component sizes. In order to achieve this, passive components like capacitors and resistors which are components necessary in almost every electronic circuitry are embedded in the multi-layered PCB.

  Boolean algebra simplification examples and solutions  Example 1: Simplify the Boolean expression   

What is a Boolean expression? A Boolean expression is an expression in which symbols are used to represent logic. Any symbol can be used, however, letters of the alphabet are generally used. Since the logic levels are generally associated with the symbols 1 and 0, whatever letters are used as variables which can take the values of 1 or 0. What is Boolean Algebra? Boolean algebra is mathematics of logic. It is one of the most basic tools available to the logic designer and thus can be used effectively for simplification of complex logic expressions. Other useful and widely used techniques based on Boolean theorems include the use of Karnaugh maps.   Simplification Of Boolean Expression using Algebraic Techniques Lets take a closer look at the different postulates and theorems of Boolean algebra and their applications in minimizing Boolean expressions. Fundamental Concepts of Boolean Algebra Boolean algebra has only two mathematical operations, addition and multiplication
