Usefull tips to Clean the Printers!

noreply@blogger.com (Kami) — Sun, 18 Oct 2009 07:17:00 +0000

Doing a printer cleaning is the best way to always have a clean and readable document.

Two type of printers.
Whether the printer is an Epson printer, HP printer, or a Canon printer the general procedure for cleaning is the same. If the printer happens to be a bigger printer, for items such as advertising on larger format materials, the process is a bit more exaggerated but essentially the same.

Every day printers
Cleaning an every day office type printer usually just entails a good solid wipe down. The real trick is to not damage the printer by using cleaning items that are meant for other cleaning activities. Cleaning chemicals to avoid include alcohol or more harsh cleaning agents. These chemicals can damage electrical areas and do more harm than good. Try and stay with light cleaning supplies like baby wipes or a damp non shedding towel. In either case, do not let water get into contact with the inside of the printer whether it is an Epson printer, canon printer or any other.

Cleaning the printer.
The very first thing to do is unplug the printer. Make sure that all lights are out and that the plug is away from the unit.
Open the front of the printer, with a damp non-shedding cloth give a light wipe down looking for dust build up or paper shards. If the paper has been appearing with black marks on the back, look inside the printer and wipe excess ink away. Make sure to wipe this area again so that there is no remaining moisture.
A clean printer cartridge is also a must clean area. Remove each cartridge and gently wipe excess ink away. Be sure not to leave any fibrous material around exit ports. The paper receiver basket may need to be removed and check underneath for dust and paper shards around the legs. A proper printer cleaning also means wiping down the basket with a mild detergent. You can also use a cleaning cartridge, which helps to clean inaccessible points of printer by hand.
If the printer has not been used for some time a head cleaning will be needed. For a complete printer cleaning in this instance go to the control panel and printers. Here the unit will be able to run diagnostic programs and get the printer heads up.

HOW TO INCREASE YOUR IPOD CAPIBILITIES

noreply@blogger.com (Kami) — Fri, 16 Oct 2009 17:48:00 +0000

If you have brought out the new iPOD then, it is time to make sure you get the maximum out of it. iPods don't come cheap, and that alone justifies the effort in taking a few precautionary measure that will help you get the most out of your iPod.

You need to keep these aspects to keep in your mind always while using your iPod!

A. Keep Your iPod Cool.

As far as IPods go, being cool is best. That means ensuring that your IPod is at about room temperature (72° F or 22° C). Do not keep it in strong sunlight, The more the iPod heats up, it lower its life.

B. Use Your iPod Regularly.

Regular use of your iPod ensures that the battery charges and discharges regularly. This prolongs both the battery life and lifespan. An iPod that is used regularly will last longer.

C.Turn Off.

You can either use the hold button to prevent the iPod from waking up due to movement or switch it off when you don't want it. This helps conserve battery power and delays the necessity for another charging cycle.

D. Disable Wi-Fi.

If you keep the Wi-Fi capability enabled always, the circuits tend to consume a lot of power even if you are not connected to a network. It is wise to enable Wi-Fi only when you need it.

E. Backlight Off.

Keep the backlight of the LCD screen off will help conserve a significant amount of power.

F. Applications.

There are several applications available for the iPod that keeps the screen from becoming dim or turning off. The applications should be used sparingly in order to maximize the iPod Capabilities.

ThePossiable Threats For WiMAX!

noreply@blogger.com (Kami) — Sun, 04 Oct 2009 06:58:00 +0000

The WiMAX Technology "802.16"
In this advanse world of technology we have so many technologies that help us in every aspect of our daily life such as transportation, communication etc. WiMAX is also one of the emerging technology that provide us high speed mobile data and telecommunication services. WiMAX stands for "Worldwide Interoperability for Microwave Access" and it is based on IEEE 802.16 standards. It works same as Wi-Fi does but it is more efficient then WiFi and it can route data to Wi-Fi that is Wi-Fi devices can take advantage of WiMAX connection. WiMAX technology provides higher speed connection up to 70 Mbps over the area of 30 miles. There is no need for line of sight connection between subscriber terminals and the base station in WiMAX technology and it can support hundreds if not thousands of subscribers from a single base station. It is also specified in 802.16 standards that it will supports low latency applications such as voice, video, and Internet access at the same time.

I have analyzed and study the risks to WiMAX technology and provide some enhancements techniques and solutions for that. Most of the threats to WiMAX technology are the security issues that need to be suitably decided for better services and security of the WiMAX network. The issues relating to security of WiMAX technology are authentication, encryption and availability. I will discuss and analyse each of the issues in detail and provide some possible enhancement for the WiMAX technology and solutions to overcome the problem.

Around 2004, WiMAX technology become progressively more discussed. Although initially designed as a fixed technology, it was being conformed in the standards to develop into a mobile technology also known as IEEE 802.16e. Many experts made claims about the WiMAX technology, some claimed it would have significantly greater range than 3G, higher data rates, would be built into all computing devices and as a effect it would take over the market for 3G like services.

In 2006, the view was that WiMax mobile networks might not be launched until the end of 2007 or 2008. It would then take some time to install the networks and require terminal devices, so it might not be until 2010 that it would be likely to see whether WiMax was having any impact on 3G.

The Diesel Generator Set

noreply@blogger.com (Kami) — Sun, 07 Jun 2009 10:36:00 +0000

The combination of a diesel engine, a generator and various devices like,

1) base
2) canopy
3) sound attenuation
4) control systems
5)circuit breakers
6) jacket water heaters
7) starting systems etc,

is referred to as a generating set or a gen set in short.
While the larger industrial generators can range from 8kVA - 30kVA for homes, small shops & offices up to 2000kVA used for large office complexes, factories. A 2000 kVA set can be housed in a 40ft ISO container and be fully packaged and portable. Sizes up to about 5 MW are used for small power stations and these may use from one to 20 units. In these larger sizes the engine and generator are brought to site separately and assembled along with ancillary equipment
Diesel generators, sometimes as small as 250 kVa are widely used not only for emergency power, but also many have a secondary function of feeding power to utility grids either during peak periods, or periods when there is a shortage of large power generators.

Diesel generator on an oil tanker Ships often also employ diesel generators, sometimes not only to provide auxiliary power for lights, fans, and winches, etc. but also for main propulsion. With electric propulsion the generators can be placed in a convenient position, to allow more cargo to be carried. Electric drives for ships were developed prior to WW I. Electric drives were specified in many warships built during WW II because manufacturing capacity for large reduction gears was in short supply, compared to capacity for manufacture of electrical equipment. [1] Such a diesel-electric arrangement is also used in some very large land vehicles.

Generating sets are selected based on the load they are intended to supply power for, taking into account the type of load, ie emergency or for continuous power, and the size of the load, and size of any motors to be started which is normally the critical parameter to chose a Gen set.

Use Of Solar Energy In Homes

noreply@blogger.com (Kami) — Mon, 16 Jun 2008 16:33:00 +0000

Man is getting benefits from nature in so many ways. One of the way is sun, we all getting benefited from. You should know that the vitamin "D" made in our boons by sun rays with out any cost. If we focus the sun is providing us energy / power where the cast of energy is not very high. Alternate energy system is developing very rapidly around the world and a one branch of alternate energy is Solar Energy.

The sun is sole and only source to get the solar energy. The solar energy is being used commercially in many parts of the world. Now it is becoming famous in homes and domestic use. Now we can light our home, feed power to water pumps and can do lots more things with solar energy. Now a days many families are using solar water heaters, solar oven, solar electric power in their homes and getting benefits form it.

A more interesting point I want to share that using solar energy you make no harmful gases, no noise and with out polluting your natural environment you can fulfill your home based energy requirements in a comparatively cheap way. In some areas whereas wind blow all the time and sun spreads its shine for longer period of the day we can get benefit from nature two ways.

Like we can erect a mini wind mill and can also use solar panels at same time. The power produced by both the systems / sources will be stored in D.C batteries and then will converted to A.C for the utilizing purposes(we can use DC system as per requirements). When air will blow at some low speed the solar panels will be work to feed the batteries and when sun will disappeared the wind mill will do the same to feed the batteries. And resultantly we will get the benefits in form of energy with out paying a single penny for the running expenditures of power.

Power Line Communication System

noreply@blogger.com (Kami) — Sat, 31 May 2008 12:47:00 +0000

PLC Power line communication, also known as power line carrier, mains communication, power line telecom (PLT), or power line networking (PLN), is a system for carrying data on a conductor also used for electric power transmission. Broadband over Power Lines (BPL) uses PLC by sending and receiving radio signals over power lines.
Electrical power is transmitted over high voltage transmission lines, distributed over medium voltage, and used by the end users at lower voltages. Power line communications can be applied at each stage. Most PLC technologies limit themselves to one set of wires, but some can cross between two levels eg, both the distribution network and premises wiring.
All power line communications systems operate by impressing a modulated carrier signal on the wiring system. Different types of power line communications use different frequency bands, depending on the signal transmission characteristics of the power wiring used. Since the power wiring system was originally introduced for transmission of AC power, the power wire circuits have only a limited ability to carry higher frequencies. The propagation problem is a limiting factor for each type of power line communications.
Data rates over a power line communication system vary widely. Low-frequency (about 100-200 kHz) carriers impressed on high-voltage transmission lines may carry one or two analog voice circuits, or telemetry and control circuits with an equivalent data rate of a few hundred bits per second; although, these circuits may be many miles / kilometers long. Higher data rates generally imply shorter ranges; a local area network operating at millions of bits per second may only cover one floor of an office building, but eliminates installation of dedicated network cabling system.

The Telecommunication Cables

noreply@blogger.com (Kami) — Sun, 25 May 2008 15:11:00 +0000

I want to tell you about
1- submarine communication,
2- amplifiers
3- repeaters
4- fiber optics
5-telecommunication network and fiber optic cables.

The cable protection committee was established in 1958 in London to protect the submarine cables.
This committee is funded by the member fiber optic cable operators and the main responsibilities of this committee to protect the submarine communication cable. Earlier telecom submarine cables were not using repeaters so there were great bandwidth problems. In 1980 fiber optical was developed it uses the optical amplifiers to transmit the signals at a very high speed. Submarine power cables are running for supplying the electrical power. Fishing, anchoring and shark fish bites can cause the damage to the cables and the damaged portion of the cable is brough Submarine communication cables are the fiber optical cables and are used for the cross Atlantic communications. Submarine cables are consisting of fiber optics and electrical conductive tube that is used to transfer the electrical signals between the repeaters. Repeaters are the network communication and telecom devices that are used to amplify the signals. Repeaters operate at the physical layer of the OSI layers model and work with the physical signals. Submarine fiber optical cables are less susceptible to failure and are very high transmission cables.

Submarine fiber optical cables are usually laid under the sea. A great research and planning is required to install the submarine fiber optic cables. Fiber optic cable is a light weight cable, 13 cm in diameter and consists of a bunch of glass fibers that are cable of transmitting the light. So the data is transferred at the speed of light through the fiber optic cables. Normally the submarine cables are not installed on the area where the fishing and ship activities are very common.

Because ship anchor and shipping vessels can be the problem for the submarine cables. Submarine telecommunication cable is a cable that is used for the telecommunication between the countries across the world. With the passage of time, the submarine cables have advancements and new technologies and communication devices are being used in the telecommunication. Submarine telecommunication cables with the high amplifier can transmit data and signals at more than 5 GB per seconds. Submarine cables were first used for the telegraphic transmission between the countries, then for telephone and then for data communication.

Today, fiber optic submarine cable is the backbone of the whole internet. In case of any damage to the submarine cables the whole communication system may be affected allot. The international t to the surface for repairing purposes. The installation and the repairing cost of the submarine cables is much high. These cables are laid in the seabed by the cable lying ships. These ships are owned and operated by the wireless and big telecommunication companies around the world. The optical fibers in the fiber optic are used as a sensor to measure heat, pressure and temperature.

Fibers are made up of transparent plastic and glass to pass the light at a very high speed. Earthquakes are also the cause of the damage for the communication cables and a major Tsunami earthquake in December 2004, caused big damages to the underlying telecom cables. Telecom cables have a large network across the world. Some of the major submarine cable companies of the world are Apollo, Pan American Crossing, Pacific Rim East, Japan-US, Columbus II, Columbus III, RJK, Eastern Caribbean fiber system and many other companies.

The Blackness Of The White

noreply@blogger.com (Kami) — Fri, 23 May 2008 13:40:00 +0000

Blackness Of The White.

The title of mine today article is very much looks like any title of a Holly Wood new release. Well, I fell it same too. But I am just going to tell you something valuable about the white fluorescent light emanating from a typical artificial light source.As we all know a few years back incandescent lamps with their yellowish light were much popular. And then revolution came in and compact fluorescent lamps (CFL) in common terms "Energy Savers Lamps" become substitute for those incandescent lamps.

The compact fluorescent lamps produce a very humble, polite, and white light which is suitable almost for everyone.But very few persons know the blackness behind this white light. I mean to say that the Cfls use a few amount of Mercury for its operation.Ttherefore users have to take much care about handling it. So do not break it.Because if the Mercury inhaled or absorbed through skin and mucous membrane then due to its neurotoxin effect it may harm the follwoings!

1. Kidneys
2. Brain (and may also cause for the followings)
3. Chest Pain
4. Cough
5. Impairment of Pulmonary Function

As we all know that the modern land fields have been made to buried the wastage produced by all of us. But the mercury which minor quantity uses in the Clfs do not tossed in to the land fields and remain dangerous for the soil , water, and the environment. So, particularly keep children away from wasted or out of order Clfs. And believe me I am not against the manufacturers or users but I fell it is my responsibility to share you the safety measures to handle the Clfs through this unique forum.

Thanks!

LCD

noreply@blogger.com (Kami) — Sun, 18 May 2008 13:03:00 +0000

About Color Liquid Crystal Display (LCD)

The LCD that can show colors must have three subpixels with
1.red
2. green
3.blue color filters to create each color pixel.

Through the careful control and variation of the voltage applied, the intensity of each subpixel can range over 256 shades. Combining the subpixels produces a possible palette of 16.8 million colors (256 shades of red x 256 shades of green x 256 shades of blue). These color displays take an enormous number of transistors. For example, a typical laptop computer supports resolutions up to 1,024x768. If we multiply 1,024 columns by 768 rows by 3 subpixels, we get 2,359,296 transistors etched onto the glass! If there is a problem with any of these transistors, it make a "bad pixel" on the display. Most active matrix displays have a few bad pixels scattered across the screen.
LCD technology is constantly evolving. LCDs today employ several variations of liquid crystal technferroelectric liquid crystal (FLC) and surface stabilized ferroelectric liquid crystal (SSFLC).

Display size is limited by the quality-control problems faced by manufacturers. Simply put, to increase display size, manufacturers must add more pixels and transistors. As they increase the number of pixels and transistors, they also increase the chance of including a bad transistor in a display. Manufacturers of existing large LCDs often reject about 40 percent of the panels that come off the assembly line. The level of rejection directly affects LCD price since the sales of the good LCDs must cover the cost of manufacturing both the good and bad ones. Only advances in manufacturing can lead to affordable displays in bigger sizes.

What Is Solar Energy?

noreply@blogger.com (Kami) — Tue, 29 Apr 2008 14:47:00 +0000

A typical solar panel

Solar energy is comes from the sun.

Solar energy can be classified in two different ways.

1- One way is through photovoltaic conversion.
2- Second way is through solar thermal conversion.

During photovoltaic conversion, solar energy is collected through panels, called solar panels. Solar panels are covered with large modules which are covered with lots of little PV cells, or photovoltaic cells. The PV cells collect the light from the sun. Once the light is inside a PV cell, there is a semiconductor made of a thin sheet of silicone crystal which takes in the photons from the sunlight. A photon is a particle of solar energy.
Within the semiconductor, energy of the photons shifts to the electrons. This energizes the electrons. Then the electrons break out of the semiconductor to get to the silicone atoms. Then they flow into the electric current. Usually a solar cell is made of a glass protective layer, an anti-reflective coat, and electric contacts.
We use PV cell systems every day. Common tools like watches and calculators are powered with PV systems. Look at the top of a calculator. Do you see the little squares at the top? Those are lots of little PV cells. Usually PV cells don’t generate much electricity. PV cells generate about ½ a volt per square decimeter. A solar panel making fifty watts of electricity is about four decimeters by ten decimeters. What if you don’t know how much energy your appliance or machine needs? Well, the answer is easy. Find out the maximum amount of watts the appliance or machine needs and multiply that by the number of hours each day it is averagely used. The answer is "the number you come up with" watt-hours. To explain it more, let’s say my microwave oven uses a maximum of 2000 watts and it is used ½ an hour each day. 2000 multiplied by ½ an hour equals 1000, so I need my PV system (my solar panels) to supply 1000 watt-hours for that microwave oven. Since I need to be ready for a crash or a change of appliance, I should really have my solar panels supply about 2000 watt-hours
Well, more about a PV cell system. Most PV cells are grouped together in arrays. Second, groups of PV cells generate a DC or direct current. That is the kind of electricity made by batteries. Some appliances and other machines like microwave ovens use AC, or alternating current, so inverters are used to change the DC into an AC.
Another type of solar energy is solar thermal conversion. In this process, there are thermal conversion panels (panels that absorb heat) which are grouped together often in a dish or trough system. The solar energy is then absorbed and concentrated into a line or a point that heats a pipe filled with fluid. These systems can concentrate the intensity of sunlight up to 10,000 times of normal sunlight.
Many people use a solar heating system to heat their house. This type of system is more effective than using a PV system to heat homes or water. You can tell the difference because solar heaters can turn 60% of the sun's energy into heat whereas PV systems can only change 12% to 15%. Solar heaters are able to heat large things like pools, water, and houses. So as you can see, when it’s heating, you are better off using a solar heater

CELL PHONE NETWORK

noreply@blogger.com (Kami) — Sun, 27 Apr 2008 09:35:00 +0000

The Cell Phone Network.
A cellular network is a radio network made up of a number of radio cells (or just cells) each served by a fixed transmitter, known as a cell site or base station. These cells are used to cover different areas in order to provide radio coverage over a wider area than the area of one cell. Cellular networks are inherently asymmetric with a set of fixed main transceivers each serving a cell and a set of distributed (generally, but not always, mobile) transceivers which provide services to the network's users.

Cellular networks offer a number of advantages over alternative solutions:

increased capacity
reduced power usage
better coverage
A good (and simple) example of a cellular system is an old taxi driver's radio system where the taxi company will have several transmitters based around a city each operated by an individual operator.

ALTERNATE ENERGY SOURCES

noreply@blogger.com (Kami) — Thu, 24 Apr 2008 15:49:00 +0000

ALTERNATE ENERGY
The demand of energy of the world is growing day by day. On other hand the supply of the fuel I may say the Black Gold is slightly decreasing. For this reason the prices of the fuel / oil are touching the highest levels. It is also becoming difficult to afford the owned vehicles to put on road.
And to keep the oil based power houses operational because as the generation cost raised the profit decreases and it became burden to end users which is always happens. In my opinion the solution for all aforesaid problems only to produce Alternate Energy which may be through?
1. WIND
2. SOLAR
3. GEOTHERMAL
4. SAFE NUCLEAR
5. BIO GASS ENERGY

Through above mentioned all alternate ways we can produce a cheap envoinent friendly energy .which will not only be fruitful to us but also for our next generations at all. One point I would like to discuss that the initial coast will not less to set any alternate system to produce the energy .But once Any alternate system established it will be one time investment and shall pay forever.
The option to adopt a specified alternate way / system depends upon the geographic conditions of any jurisdiction. The area where the sun remain rise for a long time of the day can opt SOLAR ENERGY. Likewise the area where the wind blow and can drive the wind mile there will be positive possibility to install wind gen system.
The nuclear energy can also set up if the safety measures are observed up to the mark Hydel Power generation is also a cheap way to produce the energy and it also help to irrigate the fields.

Low Voltage Power Distribution

noreply@blogger.com (Kami) — Wed, 23 Apr 2008 15:40:00 +0000

In electrical engineering distribution is very typical field all the power a system generates and all the power a system transmittes will be un usefull if their is not a reliable Power Distribution System.

It is also diversified in high voltage and low voltage distribution system.

The low voltage is the most use full source for any domestic or a light load commercial purposes and the all the electric utilities companies got their revenue and profit through the low voltage power distribution system.

noreply@blogger.com (Kami) — Mon, 21 Apr 2008 14:50:00 +0000

The basic circuit breaker consists of a simple switch, connected to either a bimetallic strip or an electromagnet. The diagram above shows a typical electromagnet design.

The electricity magnetizes the electromagnet. Increasing current boosts the electromagnet's magnetic force, and decreasing current lowers the magnetism. When the current jumps to unsafe levels, the electromagnet is strong enough to pull down a metal lever connected to the switch linkage. The entire linkage shifts, tilting the moving contact away from the stationary contact to break the circuit. The electricity shuts off.

A bimetallic strip design works on the same principle, except that instead of energizing an electromagnet, the high current bends a thin strip to move the linkage. Some circuit breakers use an explosive charge to throw the switch. When current rises above a certain level, it ignites explosive material, which drives a piston to open the switch

Steper Motor Technology

Fundamentals of stepper motor drive technology
Classic and inexpensive: Drives with stepper motorsStepper motors are ideal for applications where cost optimisation is more important than speed and dynamism.
High-end axis controller SPC 200The SPC 200 can control up to 4 pneumatic or electrical axes. One of the main development criteria was ease of use:
Record selection: for positioning tasks with fixed traversing movements which can simply be called up via I/Os.
Program mode: with up to 100 programs for solving the most complex tasks or calculating and changing positions; I/Os control the process
Quick commissioning using the WINPISA diagnostic and programming tool
The PROFIBUS fieldbus interface facilitates direct reading and writing of the position data. You can calculate, select and archive the position in a PLC and then download it directly into the SPC200. A functional module for the Siemens S7 controller family provides assistance.

Basics Of Camcorder

The Basics
A typical analog camcorder contains two basic parts:
A camera section, consisting of a CCD, lens and motors to handle the zoom, focus and aperture
A VCR section, in which a typical TV VCR is shrunk down to fit in a much smaller space.
The camera component's function is to receive visual information and interpret it as an electronic video signal. The VCR component is exactly like the VCR connected to your television: It receives an electronic video signal and records it on video tape as magnetic patterns (see How VCRs Work for details).
These two sections are easily seen in the following photos.

About Camcorders?

noreply@blogger.com (Kami) — Mon, 14 Apr 2008 14:48:00 +0000

In most of the world, camcorders, or video camera-recorders, have been a familiar sight for nearly 20 years. People take them everywhere: to school plays, sports events, family reunions and even births! When you go to a popular tourist spot, you are surrounded by them. Camcorders have really taken hold in the United States, Japan and many other countries around the world because they are an extremely useful piece of technology that you can own for under $300 (or more than $100,000).
How can such a small device do so much? Particularly for anyone born before the 1980s, it's simply amazing that quality video cameras are now readily available as consumer items, and that they're so easy to use. In this article, we'll look inside these extremely popular devices to find out what exactly is going on. We'll explore traditional analog camcorders and also look at the technology used in digital camcorders.

The Working Of Electronic Oscillater

noreply@blogger.com (Kami) — Mon, 14 Apr 2008 14:31:00 +0000

Oscillators are important in many different types of electronic equipment. For example, a quartz watch uses a quartz oscillator to keep track of what time it is. An AM radio transmitter uses an oscillator to create the carrier wave for the station, and an AM radio receiver uses a special form of oscillator called a resonator to tune in a station. There are oscillators in computers, metal detectors and even stun guns.
To understand how electronic oscillators work, it is helpful to look at examples from the physical world. In this article, you'll learn the basic idea behind oscillators and how they're used in electronics

About Electronic Engineering

noreply@blogger.com (Kami) — Mon, 14 Apr 2008 14:10:00 +0000

Electronic engineering is a discipline dealing with the behavior and effects of electrons (as in electron tubes and transistors) and with electronic devices, systems, or equipment. The term now also covers a large part of electrical engineering degree courses as studied at most European universities. In the U.S., however, electrical engineering implies all the wide electrical disciplines including electronics.
In many areas, electronic engineering is considered to be at the same level as electrical engineering, requiring that more general programmes be called electrical and electronic engineering (many UK universities have departments of Electronic and Electrical Engineering). Both define a broad field that encompasses many subfields including those that deal with power, instrumentation engineering, telecommunications, and semiconductor circuit design amongst many others

History Of ICT

noreply@blogger.com (Kami) — Mon, 14 Apr 2008 14:03:00 +0000

Information Communication Technology (ICT) has been largely limited either for peer to peer communication, or expert to audience communication. In peer to peer communication I would include exchanging information electronically, say e-mail. In the second category I would include information through books, newspapers, magazines and websites whether maintained by commercial establishments, government agencies or educational institutions. The information transfer by this mode was largely one-way, from the expert to the targeted audience. The targeted audience has had no choice but to accept the information as it is presented. Because the person(s) responsible for creating information was not totally aware of the capabilities, likes, limitations of the targeted audience. For example, even when a fraction of the targeted population was not really be comfortable with language in which the information is presented she had no alternative. Same was the case even when the targeted person did know a particular language s/he may be hampered by the dialect. The information was usually presented as text only even though the target may not be always comfortable in reading text. In short, the technologies often used to fall short of the real requirements of information recipient. Thus there was a huge potential for the developing ICTs that will suit the pockets, tastes and real requirements of a burgeoning population of information seekers.
Till a decade ago, the Internet that was a vehicle to disseminate information from a selected few to the rather affluent sections of the society was mistakenly viewed as the technology for the future of communication. But in the last few years the indicators point to changes that may yet again revolutionize information communication.

What is Aerospace Enginerring

THIS PAGE IS UNDER CONSTRUCTION

Aerospace comprises the atmosphere of Earth and surrounding space. Typically the term is used to refer to the industry that researches, designs, manufactures, operates, and maintains vehicles moving through air and space. Aerospace is a very diverse field, with a multitude of commercial, industrial and military applications.
Aerospace is not the same as airspace, which is a term used to describe the physical air space directly above a location on the ground.
