Series and parallel circuits

to store memory. This computer still made a larger impact because numerous invention is still used today, they include, “a binary system of arithmetic, separate memory and computing functions, regenerative memory, parallel processing, electronic amplifiers as on-off switches, circuits for logical addition and subtraction, clocked control of electronic operations, and a modular design” (www.ece.iastate.com). This computer led to a controversy over the ABC. This was because J. Presper Eckert and…

The Impact of Wind and Solar Variability in Grid Network 1. Introduction The renewable energy development has accelerated over the last decades. Renewable energy can benefit in such a way in various point of view. In an economic perspective, this type of energy has been more economically accepted in the market due to the decline production cost and no requirement of fuel and hence is relatively safe from fluctuated fuel price risk. Moreover, this type of energy can be found in many locations in…

“What did you learn today?” Coming home from my first day of preschool, I recall my parents asking me that renowned question. I cannot, however, recall what I said to them or anything I learned that day. More than eleven years later, I could organize a list to explain each subject, every topic we covered that day, and all of the information that I memorized, but this ordinary explanation would not include everything that I learned. Having a standard public school education, I look back on…

problem by provide frequency control in milliseconds Harmonics. This is can be managed by installing inverter which correcting harmonics. Unintentional islanding. This effect occurs when distributed generation delivers power to networks even after circuit breakers have disconnected that part of the networks from main grid and associated generator. This can be minimized by employing grid inverter technology which includes anti-islanding features. Solution to PG-DG…

1.0 Introduction A computer is an electronic device that manipulates information, or data. It was originally given to humans who performed numerical calculations using mechanical calculators, such as the abacus and slide rule. It has the ability to process, store and retrieve data and not only that a computer can also be used send to email, browse the internet for information, saved soft copy documents in the hard disk. The great advantages is it can perform multiple task such accounting formula…

Soil-Plant-Atmosphere continuum This chapter explains the concept of soil-plant-atmosphere continuum (SPA) and its fundamental principles. It also examines the role of water in the SPA continuum. A model for soil-water balance, its components and the way in which it can be determined will be also presented, taking into account the different uncertainties that could affect the measurements. 1.1 Terminology The SPA continuum is defined by the movement of water from the soil to the root through…

Fieldwalking is a systematic surface survey based on human ability rather than technology; a group of people walk parallel to each other transecting a site, looking for any artifacts that are then flagged or collected and noted down. This type of surveying is well established in its use, alt-hough technology like GPS location and aerial photography have increased its…

While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…

ELECTROCHEMICAL SUPERCAPACITOR – APPLICATION AND GLOBAL DEMAND ABSTRACT: The steep increase in the energy utilization leads us to search for a perfect alternative that can replace the conventional source and introduces a new-generation capacitors called supercapacitors with incredible storage capacity. Much research and investment have been carried out in this impressive technology. It is same as that of the normal capacitor the only thing is it utilizes higher surface area electrode and…
