The LED TVs...new era of Tele-vIsIoNiNg

Till today it was the flat screen, thin screen that attacked the television market and became popular in no time. Now its the LED TV that has many things more to give. All must have seen the ads and wondered what's the difference. Here are some facts about the most spectacular way of TV viewing!!
The LED tv is actually an LED-backed LCD television that uses LED Backlighting in LCD televisions. These LEDs come in 2 forms, Dynamic RGB LEDs that are positioned at the back of the display panel and Edge LEDs that are positioned around the rim of the screen that diffuse light evenly throughout the display, behind the panel.

The current LCD televisions use CCFL(Cold Cathode Fluorescent Lamps) as backlight providers. An LED backlight offers several general benefits over regular CCFL backlight TVs, typically higher brightness. Compared to regular CCFL backlighting, there may also be benefits to color gamut. LED-backlit LCD TVs are considered a more sustainable choice, with a longer life and better energy efficiency than plasmas and conventional LCD TVs.

Because LEDs are able to be switched on and off more quickly than CCFL displays and can offer a higher light output, it is theoretically possible to offer very high contrast ratios. They can produce deep blacks-LEDs OFF and a high brightness-LEDs ON.

The major promoters of LED TV are: Samsung Electronics, SONY, Panasonic, Toshiba, LG Electronics, Philips and ProScan. Some spectacular pics of LED TV below:

The Humming Birds....

The humming birds are among the smallest of the birds and are one of the quickest bird species in the planet with flying speeds at 54kmph. They can hover in the mid-air by rapidly flapping their wings 19-20 times per second. They can also fly backwards, and are the only group of birds to do so. These birds drink Nectar from flowers as the bees do and can assess the amount of sugar present in the flowers. They also prey on insects to balance the diet.


Here are some beautiful pictures of the bird (various species) from the National Geographic Society's collection. Please visit the site for more stuff about many other beautiful creatures on the planet.

Beautiful Flowers of India....

The beauty of our nation lies in its greens and flowers. Check some unusual flora and an unusual land that houses a part of the so called heaven...on earth...the Valley of Flowers

Brahma Kamala:















This one is native to India and blooms only in the night for about 2 hrs. This beautiful thing is also called the 'Cradle of Jesus', for its superb structure.


Paarijatham:

This is one of the most sacred flowers in the country. In the flowering season it blooms in hundreds in a tree and its garlands are considered to be special offering to the gods.

Champa:


This flower is well known for its fragrance, that sometimes faints a person or brings headache. Still very sacred. The sister flower, 'Naga Champa' is also in the same form and sacred too.


Shanka Pushpa:
Considered sacred in south India, it is known for the shape specified in the name.

Maha Kamala:

This is our nations pride. The lotus is a spectacular sight and sacred because it blooms beautifully in the dirtiest swamp.

Karna Kundala:
This one is also called Gauri Pushpa. Sacred too...

Some brutalities of the recent Naxal Attack

This stuff was reported in Yahoo News....

"THE Maoists came in large numbers and many of them were women. The attack was so brutal that the assailants chopped off limbs from jawans' bodies to make sure they had died". These are the gory recollections of 21-year-old Central Reserve Police Force (CRPF) constable Aditya Singh - one of only two jawans from the 62nd battalion who survived the massacre by Maoists in Chhattisgarh on Tuesday.

Aditya has lost vision in his left eye after suffering bullet and splinter injuries during the bloodbath. He is currently admitted at the All India Institute of Medical Sciences (AIIMS)' s Rajendra Prasad Ophthalmic Centre, where he will undergo surgery soon.

Divulging fresh details about the attack, he said: ''The CRPF camp was in a jungle, so there were few villagers who reached the spot before reinforcements could arrive. But even they were too scared to help us.

The CRPF men who came later, took me and my other injured colleague to the local hospital.'' Aditya further recounted: ''The Maoists were armed to the teeth with sophisticated guns, bombs and ammunition. They butchered the CRPF jawans in cold blood.'' He said the encounter between the jawans and Naxalites lasted more than two hours. The Naxalites were well- prepared and had placed bombs all over the area. Aditya said though the Naxalites heavily outnumbered the CRPF jawans, the latter fought till their last breath.

'' All of us fought hard and injured many of them. I fired more than 120 bullets at the Naxalites and hit several cadre. Since I was running short of bullets, I moved to a side to take position. A bomb placed at the spot went off as soon as I stepped there,'' Aditya said. ''Many jawans died and eight of us got injured after the high-intensity blast took place,'' he added.

When the explosion took place, Aditya lost consciousness.

Even as he slipped in and out of consciousness later, he has a vague recollection of what the Naxalites did to him.

''I collapsed in a heap on the ground after the blast and blacked out. Later, I was semiconscious and remember that they came near me and kicked me. But I didn't move because my colleagues were all dead and I couldn't offer any resistance as the Naxalites' numbers were large. I wanted to kill all of them, but couldn't move because of my injuries,'' Aditya said.

''They thought I was dead and went away. I lay injured and bleeding at the spot with a pile of my colleagues' bodies strewn all over for more than six hours till the CRPF personnel arrived and rescued us,'' he added.

Aditya was airlifted from Raipur to the National capital on Wednesday and admitted at the Jai Prakash Narayan Apex Trauma centre of AIIMS at 9.30 pm. In view of the serious nature of his eye injuries which have left him partially blinded, he was later referred to the Dr Rajendra Prasad centre.

Aditya was also hit by a bullet on his chin.

Although Aditya has lost vision in his left eye, his spirits are not broken. In fact, he is raring to have a go at the Maoists even as he recuperates in the hospital.

''They have killed my people. They are disturbing the country's peace. The Naxalites should be punished,'' Aditya said. ''I am waiting for the day when I will recover from my injuries. Then I will return to teach them a lesson,'' he added. Soon after Aditya was brought to the National capital, officials from the Composite Hospital CRPF, New Delhi, were sent with him to the AIIMS as attendants.

Aditya was initially admitted to the Maharani Hospital in Jagdalpur in Chhattisgarh where he was given first- aid.

The CRPF constable was then referred to the Ram Krishan Eye Care Hospital in Raipur from where he was sent to the AIIMS for tertiary care and treatment.

Aditya belongs to Bulandshahr in Uttar Pradesh. He joined the CRPF in 2007. Raipur was his first posting. Aditya is married and has two sons. His father Uday Singh retired from the state's prisons department.

The Silent King of Processors - AMD ...Rises again


The microprocessor world has been consistently ruled by Intel and AMD(Advanced Micro Devices) processors since a decade. People say that an Intel chip is a good choice, while AMD chip is a smarter one. Today, the competition between the two has made AMD to come up as a new face, the AMD hexa-core Phenom II X6, with Turbo Core Technology.

AMD has lived through its Kryptonite5, Kryptonite6, Athlon, Duron, Sempron, Athlon 64, Opteron,Turion and Phenom II x4 processors, and has maintained its scalability and efficient power management systems, giving away a kit of all smart technologies. The brand new Phenom II x6 has an edge over Intel regarding the multicore-technology. It provides a highly functional hexa(6)-core chip with 3.6-3.7Ghz clock speed. There is a l3 cache provision of capacity 6Mb...!!! What to say...welcome to the world of multicore computing...!!!

People say that even Intel has a Quad-core, i5 and i7 processors with high performance. Well, whatever be the reason, if you ask your computer operator about which which one would be his choice, the answer is AMD. This wonderful piece if technology has maintained its popularity by not exhibiting itself, but by its technology and performance itself. An Intel machine might showcast itself as a 3.6 Ghz while it gives a part of it in our environment, but an AMD processor gives the full of it....be it a desert or a tundra.




AMD seems to have an edge over Intel in terms of scalability and uniform chipset architecture across all platforms and hence making the Phenom II X6 processors backward compatible with existing AM3 and AM2+ sockets. The other significant advantage is the same power requirements as the existing Phenom II X4 processors.

With a less complicated overclock mechanism, AMD has docked the clock speed of three out of six cores and boosted the clock speed of the remaining three cores with higher input voltage limits to ensure optimized performance under increased workloads.
