3d technology has over the years has advanced in terms of its research.3d view simply means view from 3 angles of the user,giving a more realistic approach of the object to the user.Till now,users are required to put on the projector glasses for viewing 3d films n while playing 3d games.
This may come to an end with the latest technology developed by 3M.
3M recently announced it's plans of introducing it's new technology.
The Scotch Tape giant have created a sequential 3D optical film which allows for true auto stereoscopic 3D images on mobile phones, gaming products, and other handheld devices.Thus,hi-end mobile owners and game device owners may soon be enjoying the advent of 3D without the glasses put on.
The technology was further discussed by 3M.
The film is integrated into the backlight module and also it requires only one LCD at a 120-Hz refresh rate,which is new in technical world.Integration became simpler as the standard optical film stack was replaced by reflective stack ,a custom light guide, and 3D film ,on working about the properties of light being transmitted through the medium and it's reflexive properties.The end result achieved was that the right and left images are focussed at the same point in the viewer's eyes,thus enabling a clear image without the aid of 3D glasses,enabling a full resolution display to the user.
This 3D technology will be on display at the Korea Electronics show, October 13 to 16,2009.
Microsoft recently launched it's latest version of Operating system,known as WIndows 7 for the personal computers.This is after a time span of less than 3 years after Windows vista was launched.Initially named as Blackcomb and Vienna,it was due to release after the launch of Windows XP.It was released to manufacture on July 22,2009 and will be available in markets from october 22,2009.
WIndows 7 is more user friendly.While a lot of features have been added into its outlook,it has worked upon some features previouly existing in windows vista.Some Windows Vista features and components have been changed or removed,including the classic Start menu user interface, Windows Ultimate Extras, and Windows calendar. Three applications available with Windows Vista — WIndows Photo Gallery, Windows Movie Maker, and Windows Mail have been exclude in Windows 7.User can avail them in a separate package for free,called Windows Live Essentials.
Windows 7 comes with a number of new features, such as advances in touch and handwriting recognition, support for virtual hard disks, improved performance on multi-core processors and kernel improvements. Windows 7 adds support for systems using multiple heterogeneous graphics cards from different vendors (Heterogeneous Multi-adapter), a new version of Windows Media Center,a Gadget for Windows Media Center, improved media features, the XPS Essentials Pack and Windows PowerShell being included.Many new items have been added to the Control Panel, including ClearType Text Tuner, Display Color Calibration Wizard, Gadgets, Recovery, Troubleshooting, Location and Other Sensors, Credential Manager, System Icons, and Display.Windows Security Center has been renamed to Windows Action Center (Windows Health Center in earlier OS) which provides both security and maintenance of the machine.
The taskbar comes with a new visual look.The Quick launch has been replaced with pinning applications.This is a new change in the outlook.The buttons for the pinned applications are integrated with the taskbar buttons.The two additional features in WIndows 7 are the Aero peek n Aero Snap.On taking the mouse over the Aero peek button,makes all the windows opened transparent n gives a look at the desktop.On reclicking it,all the windows are restored.Aero Snap automatically maximizes a window when it is dragged to either the top or left/right edges of the screen.This permits the users to snap documents or files on either side of the screen to compare them.This functionality is also accomplished with keyboard shortcuts.
Unlike in Windows Vista, window borders and the taskbar do not turn opaque when a window is maximized with Windows Aero applied. Instead, they remain transparent in Windows 7.
Hardware requirements are needed to be checked out before installing Windows 7 as 1 GHz 32-bit processor,1 GB of RAM,16 GB of available disk space,etc are some of the necessities that are to be supported by the hardware configuration of the pc.One can download the Windows upgrade advisor from the microsoft site to have a Windows 7 compatibility check on their personal computer.
Overall,although the look of Windows 7 may seem to be nothing more than some polished outlook, it has features which vary from driver support to multitouch groundwork for the future, from better battery management to the most user-friendly interface Microsoft has ever had.
Will the release of WIndows 7 see the end of WIndows XP????
A total station is an optical instrument used in modern surveying and arhaeology as well as by police , crime scene investigators, private accident reconstructionists and insurance companies to take measurements of scenes . It is a combinatoon of an eletronic theodolite (transit ), an electronic distance meter (EDM) and software running on an external computer known as a data collector.
With a total station one may determine angles and distances from the instrument to points to be surveyed. With the aid of trigonometry and triangulation , the angles and distances may be used to calculate the coordinates of actual positions (X,Y and Z or northing , easting and elevation ) of surveyed points , or the position of the instruments from known points , in absolute terms.
Measurement of distance is accomplished with a modulated microwave or infared carrier signal , generated by a small solid - state emitter within the instrument's optical path , and bounced off of the object to be measured . The modulation pattern in the returning signal is read and interpreted by the onboard computer in the total station . The distance is determined by emitted and receiving multiple frequencies , and determining the integer number of wavelengths to the target for each frequency . Most total stations use a purpose - built glass Porro prism as the reflector for the EDM signal , and can measure distances out to a few kilometers , but some instruments are " reflectorless" , and can measure distances to any object that is reasonably light in color , out to a few hundred meters . The typical TotalStation EDM can measure distances accurate to about 3 millimeters or 1/100th of a foot.
WAP is taking over the world at a very rapid pace. It is growing as it has some unique advantages, which are:
- Efficiency: WAp is more efficient as it enables client and server data exchange using least amount of data transfer speed. The WAP protocol is more efficient than TCP/IP or HTTP.
- Predictability: Anyone person or organization never controls web. But on the contrary, a standard WAP forum, which has a type control over the development of WAP and related standards as well as devices, controls WAP. Because of this, only some specific WAP devices are present having the corresponding WAP gateways and hence the result are predicted.
- Dynamic behaviour: The WAP client is coded in a special language known as WML (Wireless Markup Language), which works on the script that reads the key strokes which causes change in the result on the WAP device. Even some special timers can be set through which depending on the time change various actions can occur resulting in dynamically changing web pages on the WAP browser.
- Working for constraint clients: As discussed wireless communication has to work on very minimal resources such as low capacity device and narrow data transfer rate. WAP allows the usage of such devices very efficiently by putting much of the server. To transfer a compact data using special markup languages i.e., WML and WML Script is also a main feature.
- Scalability: As WAP is based on a layered architecture, it is unique featureof WAP that each layer can develop independently of others. This makes it possible to introduce new concepts without major changes in the overall architecture. WML and wireless markup language scripts (WML Script) are used to produce WAP content. They make optimum use of small displayes and develop in such a way that the site navigation can be performed with just one hand.
E-mail has become very popular because of various reasons which are:
- Free of cost: It is almost free of cost. The cost incurred is the cost of connecting to Internet.
- Almost instant: The message is almost sent instantly. The only delay in this can be because of heavy traffic on the URL on which the data has to be sent.
- Various possible ways of making it possible: E-mail address can be obtained at various domains. So it is possible to send the message to various addresses at the same time in a singal stroke.
- Reduction of paper work: The letter is not required to be typed on the paper rather it can be sent in the soft copy reducing the paper work.
- Increases efficiency: No time is wasted in typing, printing, going to market, to get ticket or to post the letter. Everything is istant, so it is very efficient.
- Global accessibility: Another main feature of E-mail is that you can receive the mail at your house, office, cyber café or any other place around the world. Your mail box is global and you can access it from anywhere.
- Easy to keep the records: When E-mail are done using special mail softwares like outlook express or Microsoft Outlook, the mails received and sent are stored in various folders, which can be deleted if not required. So it is very easy to maintain the records.
- Facility to resend: if you send an E-mail and user says he has not got it, it is very easy to send him the mail again and it is very easy to send the same mail to somebody else as well.
- Easy maintenance of address book of friends: Maintaining the records like address and phone numbers is quite easy through the address book.
- Better than phone: It is good to communicate over phone, but it is not possible to send the documents through it. E-mail can also be used to send documents, pictures etc.
- No transportation cost: Since E-mail can be sent from your desktop, you need not bear the cost of going to the post office to send the letter.
