Volcanic Eruptions Released Dissolved Gases

At high pressures deep beneath the earth's surface ,volcanic gases are dissolved in molten rock. But as magma rises towards the surface where the pressure is lower ,gases held in the melt begin to form tiny bubbles". 'The increasing volume taken up by gas bubbles makes the magma less dense than the surrounding rock, which may allow the magma to continue its upward journey"." Closer to the surface ,the bubbles increase in number and size so that the gas volume may exceed the melt volume in magma, creating a magma foam". "The rapidly expanding gas bubbles of the foam can...

The Simulation And Implementation Of Multilevel Inverter

This project presents the simulation and implementation of multilevel inverter fed induction motor drive. The output harmonic content is reduced by using multilevel inverter. The multilevel inverter is build by using the PIC 16f877A microcontroller to send the signal into motor driver which can separate high and low voltage to the power Mosfet. There are the six power Mosfets which used to do the inversion from Dc battery voltage to Ac voltage. In symmetrical circuit, the voltage and power increase with the increase in the number of levels of inverter. The switching angle for the pulse is selected in such...

Xray Is An Electromagnetic Radiation

By definition, X-Ray is an electromagnetic radiation which is having a short wavelength between 0.02Å to 100Å (~10-10m) emitted when electrons jump from a higher to a lower energy state. On the other hand, Crystallography is a study about crystal. The word ‘crystal’ it self is a molecule in which the atoms are arranged in the orderly manner where it consists of a periodic arrangement of the unit cell into a lattice. Thus, we can define X-Ray Crystallography (XRC) in a simple word as a technique or tool to investigate a 3-D molecular structure of a compound by...

Analyzing Transmission Network Expansion Planning

Abstract—This paper presents a multistage transmission network expansion planning (TNEP) model based on a disjunctive formulation. Since the proposed TNEP model is a mixed-integer linear programming (MILP) problem, a renovated benders decomposition (BD) scheme entangled with a differential evolution algorithm (DEA) is applied to alleviate the computational cost of optimization problem. The solution procedure decomposes the original MILP problem into a master problem, applying a DEA to acquire potential solutions for integer programming (IP) problem, and two sub-problems, applying linear programming (LP) method to acquire potential solutions for LP problem. Over a course of successive iterations the master problem is...

Energy Consumption In Building Sector

Energy consumption in building sector is an important factor in the increase of the total energy utilization. The utilization of solar energy has traditionally been divided into two fields in a single device are solar thermal and photovoltaic. Photovoltaic as the name itself says that, the conversion of solar energy to electricity, by the usage of silicon based solar cells and Solar thermal on the other hand, concerned with the utilization of solar radiation to provide useful heating....

Motor Startes In The Automobile Industry

A motor starter, also known as starting motor and starter, is an electric motor that rotates the internal combustion engine and causes it to power up. The motor starter is made up of a powerful DC electric motor and a starter solenoid (electric switch) and requires a very high current in order to turn over the engine and start it. In the car, the motor starter begins when the key is put into the ignition and turned to the start position. At this point, the battery voltage goes through the starter control circuit and activates the starter solenoid. This process...

Wind Power Generation System Using Neuro

This paper presents a new approach in neuro-fuzzy based variable Speed Wind generation system. The use of an Estimator-based neuro Fuzzy Logic control technique to govern the system is proposed. A neuro fuzzy controller tracks the generator speed with the wind velocity to extract the maximum power. A second neuro – fuzzy controller programs the machine flux for light load efficiency improvement. The aim of neuro fuzzy controller is to establish maximum power delivery to the grid from available wind power. Fully-controlled wind turbine which consists of induction generator and back-to-back converter is under estimate. The...

Introduces New Regulations To Prevent Crane Accidents

The Occupational Health and Safety Administration (OSHA) began publishing statistics on crane accidents in 1996. Since then, there has been over 2000 deaths relating to crane accidents and over 100,000 injuries. (Peeks) In the past decade, tower cranes have risen above our skyscrapers raising equipment, building materials, and people higher and higher. During 2007, there were over 16 cranes rising 100 feet or higher in Seattle. In Dubai, there were over 230 tower cranes in use at a single time, 16 of which within one square Acre of land.

The Military Aircrafts

Initially military aircrafts were utilizing fibrous composite materials in small quantities during 1960s and 1970s after which their exploitation in the aerospace industry has dramatically increased. By the commencement of 1980 era the composites were being used by civil aircraft manufacturers for a variety of secondary wing and tail components such as rudder and wing trailing edge panels and the first airplanes to fly under their own power were constructed over a century ago (Flower and Soutis, 2003). During 1980s, engineers became more inclined towards higher strength in the aluminium alloys in an effort to conserve weight. Different aluminium...

Switched Lans And Network Design

The Local Area Networks (LANs) can serve only a small geographic area and there is a limitation for the total number of hosts that can be attached to a single network. In order to communicate between the hosts network devices like hubs and switches are used. Thus a set of LANs that are interconnected by switches will form switched LANs and this lab is all about the performance evaluation of the switched LANs....

Comsats Institute Of Information Techonology Islamabad

Communication may be broadly defined as a process of interacting by transferring information from one point to another. The use of light (optical carrier wave) for communication has been common for many years. Earlier, man used fire, smoke signals and reflecting mirrors for communicating. In1880 Alexander Graham Bell transmitted speech using a light beam [1]. Though investigation on optical communication continued in the early part of the twentieth century [2, 3] its use became limited due to the lack of suitable light sources and the problem that light transmission in the atmosphere is limited to line of sight and gets...

Distributed Generation Installation Growth Considering Network Power Quality

The distributed generation (DG) is an electrical power generation system based on dispersing small-scale power generation unit on power system. The DG is generally connected to the distribution network although it is possible connecting to transmission network [1],[2]. Nowdays, the DG has been developed rapidly. The development is supported by investment and electricity market opening for DG [3]. From regulation aspect, DG is also possible to be built and owned by final user/community in addition to project developer and utility [4]. DG plant technology is also designed to be more efficient and environmental friendly. Thus, it is not surprising that...
