Noise pollution (or environmental noise in technical areas and venues) is termed as displeasing or annoying human or mechanically caused sound that is or can be described as alien to the environment. I guess to most of us the major source of this pollution would come from transportation systems, as anyone who has tried to hire a car from the main AVIS car rental depot at Heathrow Airport would testify to. Based on the perimeter road at Heathrow sometimes the noise of landing 747’s can make it a little difficult explaining to the attendant what problems you may have had (or not) with the car you are returning. The bottom line is that we live in a noisy world and by that I mean not just the sound of cars and traffic etc but the way we live our lives and perhaps more importantly where we are now living and the density of the accommodation we provide ourselves.
Nowadays basically we have people living on top of each other, underneath each other and in fact all over the place and more importantly interfacing with modern day technologies in ways that hitherto would have thought to have been impossible. As such the use of the acoustic foam and the noise dampening systems are essential.If we take for example the situation in many cities nowadays when we have whole plethoras of modern communication links such as underground railway systems, over ground railway systems, modern two-way flyovers and in fact transports communications and residential accommodation right next to each other. Without adequate noise reduction systems in place and incorporated within the structure of the residential and work accommodation than pretty quickly life within these new cities would become pretty intolerable.
As we have said before, enter stage left acoustic foam. Without these new technologies providing the noise insulation, the quality of life in most built up areas would be appalling. At this point it becomes pretty obvious to all concerned quite what a debt we owe to noise reduction systems and soundproofing in general that quite often mere words on no longer enough.

Flat Screen Monitors
You probably are already aware that there are two types of computer monitors available today: the big and clunky cathode-ray (CRT) tube monitors and the newer flat screen monitors. These flat panel monitors have a number of advantages over the older type of computer monitors. They are far sleeker, more space-saving and weigh much less. Flat screen monitors are also designed to be more energy-efficient and reduces eye strain. Flat screen monitors use the technology called Liquid Crystal Display or LCD. There are also flat screen CRT monitors available. Both LCD flat panel monitors and CRT flat-screen monitors are fast gaining popularity as a much sleeker and more modern alternative to traditional, bulky monitors of yesterday.An LCD or liquid crystal display is characterized by a thin and flat display device that is composed of either colour or monochrome pixels that are arranged in front of a light source or a reflector. There are two types of LCDs: Tran missive and reflective displays. These types differ according to the source of light. A reflective LCD is illuminated by exterior light. A common example of a reflective LCD is the display of a digital watch. Meanwhile, a transmissive display draws its light source from the back through a backlight. This category of LCDs usually requires high luminance levels. Televisions, computer displays, PDAs and mobile phones use transmissive LCDs.
Flat screen monitors have significant advantages over the traditional CRT monitors. Because these monitors are perfectly flat visually and physically, they offer a clearer, more vivid and undistorted pictures from any angle. The images on a flat panel monitor is much more crisp and high quality. This is the reason why flat screen monitors significantly reduce eye strain among its users, another important advantage. There is no curvature on the screen’s surface that will distort any on-screen images. And since the pictures are sharper with more brilliant colours, staring at a flat screen monitor becomes more of a pleasure than a strain. Flat screen monitors are also much more ergonomic. This means that these types of monitors follow ergonomic requirements and thus add comfort and convenience for the worker. The flat screen monitor is viewable from any angle and is typically fitted on a swivel base with adjustable headlight. This allows for more freedom of movement for the user since the flat screen monitor can be easily adjusted to meet the specific viewing needs. Flat screen monitors are also very space-efficient taking up less desk real estate than older computer monitors. Most LCD flat screen monitors are only about an inch thick and weighs nearly five kilograms.

Career in Architecture
Anyone who is talented in design, imagining how a house or building could be constructed or who likes to draw may have the talent to find a successful career in architecture. An architect is responsible for designing and planning the interior workings and foundation of a home or building. Architects are responsible for drawing up plans and blueprints for towering city buildings, small country homes and luxurious mansions. A successful architect must be versatile and imaginative while maintaining respect for the customer’s wishes. There are a number of jobs available in the world of architecture and designing homes may be a career in itself. A qualified individual may produce a blueprint, which consists of both interior and exterior elevations, foundation and floor plans, roof details, electrical layouts, cross sections and other general instructions. In order to find a career in architecture, an individual must become licensed through an accrediting agency. In addition, an architect must become familiar with building codes, local laws and regulations and must be skilled in their craft. In order to learn this information, architectural hopefuls must pursue a college degree and learn firsthand how the process works.
In addition to designing a home or building, architecture also includes making adjustments to already developed plans. This may include altering blueprints for a home or business in order to be customized to the individual’s needs. Many individuals hire an architect to design their construction, but others decide to enlist a professional later. If problems arise in the construction or they simply need a helping hand, many individuals and companies turn to the world of architecture for a professional evaluation and redesign. Concerns surrounding both energy costs and safety have, in recent years, prompted many areas to require an architect’s seal be placed on a blueprint prior to construction. In addition to the actual design process, many architects review plans and offer consultation services on independent creations.While many architects find great success within a firm or working directly with homebuilders, many find that they are happy working on a freelance or consultant basis. This means that they work directly with the company or individual, own and operate their own business and handle every decision within the company. The freedom of self employment in the world of architecture can be very fulfilling, both financially and emotionally. Much like a doctor, lawyer or accountant who branches out into their own private practice, an architect may also enjoy that same freedom.

How to choose hard drive for your computer
Hard drives come in many different sizes and configurations. How much data a hard drive can hold is measured in gigabytes (GB). The latest hard drives can hold anywhere from 80 GB to 1000 GB (1 TB)! When buying a hard drive, size isn't the only factor to look at, however. By choosing the right hard drive for your needs, you'll enjoy your computer more. Hard drives are so inexpensive these days it makes no sense whatsoever to get one that doesn't fulfill your needs. For business or basic home use, an 80 GB hard drive should suffice. If you plan on downloading music, movies, or installing a lot of games on your computer, your hard drive should be at least 160 GB. For laptop users, the same space requirements apply, however, many laptops come with small hard drives.
You can have a huge hard drive, but it will be worthless if it doesn't move data fast enough for your computer! To find data, hard drives have platters on spindles that spin, similar to a CD. How fast a hard drive spins is measured in RPM (revolutions per minute). The higher a hard drive's RPM is, the faster it will perform. Desktop hard drives almost always have 7200 RPM hard drives. Laptop hard drives can range from 4200 RPM to 5400 RPM for budget and midrange uses and 7200 RPM for high end use. Hard drives with RPMs of 10,000 or more are available, but those are mainly for gamers, computer enthusiasts, and servers.
A hard drive's cache is also another important performance indicator. A hard drive's cache will hold frequently accessed data for faster access by the computer. A good hard drive will have at least 8 MB of cache. As with RPM, the more cache a hard drive has, the better. Hard drives generally have either an SATA or IDE connection. Both connections are for attaching the hard drive to the motherboard via a cable so that data can be sent and received to and from the computer and drive. SATA is the newest connection and is better than IDE in that it can be faster and uses a much smaller cable. IDE, however, is just as fast as IDE in real world performance testa and hard drives that use IDE are cheaper than SATA hard drives. However, IDE hard drives use large cables that can restrict airflow. Fortunately, you can buy a rounded IDE cable that is not as big for $5-$10 at almost any computer supply store or online computer part retailer, such as Newegg.com or Fry's Electronics.

Satellite Communication Technology
Satellites have been orbiting the earth for several decades now, and are constantly contributing to the evolution of global communication. Satellite cell phones have made it possible for people to make phone calls from anywhere in the world, no matter how remote their location, and have been extremely useful in coordination of many activities ranging from scientific exploration to military operations. Portable satellite radio is another important technology that has emerged in recent years, allowing users to subscribe to and access radio channels from around the world for either entertainment or informational purposes.
One small problem with satellite communication technology, however, is the sheer distance involved in communicating with orbiting satellites, which can cause a slight delay in transmission time. This, of course, is of no consequence to satellite radio, but it can be a slight problem for two-way communication services such as broadband and phone. The only way to reduce the time delay involved in satellite transmission is to use lower orbits for satellites, thus reducing the distance involved in transmission. Lower orbits are already being used for some purposes, but there are many challenges that must be overcome in order to make such a transition. Advancements in satellite technology have been plentiful in the past few years, and more are expected in the future. It will be very interesting to watch the development of this evolving technology over the coming years and beyond.

Software Engineering
The advancement in technology that we have experienced over recent years has allowed for significant progress to be made in all the fields of activity. Companies and enterprises from all industries can take their performance and productivity to the next level by investing in information technologies. Increasing and maintaining high performance is an achievable goal, provided companies focus their efforts on enhancing the efficiency of applied tools. Dynamic control of the company’s existing applications and optimal use of its IT investments allows for the seizure of new business opportunities as well as for the development of new competitive advantages. Investing in information technology is not sufficient; companies are faced with the stringent need to find a comprehensive solution to tasks such as software design, construction, testing and maintenance. All these aspects are encompassed in what is referred to as software engineering.
Software engineering has proven to be not only an indispensable tool in the smooth functioning of a company or an enterprise, but a valuable one when it comes to performance tuning. Software engineering lies at the bottom of the constant change that we are all witnessing in the world today. Software engineering plays a major part in building the tools that enable computers to make this change. Therefore, the more pervasive computers and applications become, the more important is the role of software engineering. Software engineering encompasses everything from the development of database structures to working on embedded software or writing consumer-level applications. The integral role of software engineering in the development of software applications requires conceptual and design skills, in addition to programming ones.
Registry Cleaning Software
Are you struggling with a sluggish PC? Errors popping up all the time, programs not starting, or worse the blue screen of death? It's possible that you're suffering from registry errors on your PC and you don't even realize it. Your registry files hold a vast amount of information about your computer, its software, and hardware. Everything from file locations, device driver information, and even desktop shortcuts has information in the registry. Over time this area of your computer can become bogged down with old information. Information about programs that have since been un-installed or removed. This extra information can cause windows to hang or freeze when it goes searching for valid info it needs, only to get slowed down and thrown off track due to old files and errors.
The registry cleaning process isn't as technical as you might think. The first step is an initial scan performed by the software looking for items like we described in the previous section. These might be old deleted files, invalid registry keys, or empty lines in your registry. After the complete scan has is done the software then moves onto the repair process. You have two options to repair the troubles that the software found during it's scan. One, you can have the registry cleaning software make the corrections automatically for you. Many first time users select this as their repair method, how ever it can cause more trouble then good. The second alternative to repair the items found during the scan is to manually review each item before it's repaired. While this can take a bit more time, it will ensure that valid registry entries are not deleted during the cleaning process.

GPS enabled Cell Phones
Today, cell phones are made more innovative by applying technologically advanced applications such as GPS or Global Positioning System. Equipped with this remarkable device, cell phones can now operate beyond their basic functions. With the GPS system, cell phones can be used as a tracking device that enables people find the right places or even hunt down a relative or friend on his exact location. GPS or Global Positioning System is a device used to pin down people’s specific location anywhere on earth. The central hub of the system depends on “24 satellites” that move around the earth two times a day. The identification of certain locations was made possible using fully operational devices that include a series of receivers and satellites. 
The information gathered by the satellites are being transformed back to the earth using exact timing indicators to receivers such as GPS cell phones. In this way, the hunted person’s exact location is identified based on altitude, latitude, and longitude measurements. Today, GPS-enabled cell phones are being used beyond their usual features. With the help of GPS, people can now locate new addresses and navigate a new place without the difficulty of turning to your maps every now and then.
With GPS, cell phones can demonstrate the exact areas where to turn right or left. Hence, the need for a true GPS tracking device is lessened as more and more cell phone companies are gradually employing the utilization of GPS. Most cell phone companies believe that the utilization of GPS cell phones are important in today’s modern world.One of the probable profits that the commercial market can gain is the distribution of graphical advertisements on mobile phones with the help of GPS. Indeed, with the introduction of GPS cell phone in the market today, people will have to change their units again just to cope up with the ever-changing world of the communication industry.

At a basic level animation can be thought of as a flicker of life in objects. Animation has become popular because real life has movement and the human eye is naturally attracted to movement. Over the last 100 years animation has developed into a huge industry. Computer animation has advanced rapidly, and is now approaching the point where movies can be created with characters so lifelike as to be hard to distinguish from real actors. This involved a move from 2D to 3D, the difference being that in 2D animation the effect of perspective is created artistically, but in 3D objects are modeled in an internal 3D representation within the computer, and are then 'lit' and 'shot' from chosen angles, just as in real life, before being 'rendered' to a 2D bitmapped frame.
Animations can be used in various ways on a web page such as making a log presentation more interesting by activating charts that dynamically show changes over time. Again animated games are very popular on the Web, especially 3D games. Animation attracts the attention as it is dynamic. For example animated buttons on a web page attract more attention than the static buttons. When we speak of types of animations, the simplest type is an animated GIF. Animated GIFs are popular because they are easy to create and don’t require special software for viewing.
Flash is widely used to create animations for the Web because Flash animations are usually small in size and most Web users have the Flash player installed in their web browsers. In the future the animations on the Web will be more interactive and 3D animations will be widely used. Web animations will be used widely for education and entertainment. The gaming industry will increase its presence on the Web and support 3D and interactive animations. Animations that use simulations will be used for training and education. A lot of focus will be on multi user interactions and 3D animations and on making the Web more and more interactive.
