Boot Defragment In Windows XP

A very important new feature in Microsoft Windows XP is the ability to do a boot defragment. This basically means that all boot files are placed next to each other on the disk drive to allow for faster booting. By default this option is enabled but some upgrade users have reported that it isn't on their setup.

1. Start Regedit.
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOpt imizeFunction
3. Select Enable from the list on the right.
4. Right on it and select Modify.
5. Change the value to Y to enable and N to disable.
6. Reboot your computer.

Besides providing a rich, immersive 3D view of Mars that will aid public understanding of Mars science, the new mode, Google Mars 3D, also gives researchers a platform for sharing data similar to what Google Earth provides for Earth scientists.

The mode enables users to fly virtually through enormous canyons and scale huge mountains on Mars that are much larger than any found on Earth. Users also can explore the Red Planet through the eyes of the Mars rovers and other Mars missions, providing a unique perspective of the entire planet.

Users can see some of the latest satellite imagery from NASA's Mars Reconnaissance Orbiter and other probes orbiting the Red Planet. Viewers can learn about new discoveries and explore indexes of available Mars imagery. The new Mars mode also allows users to add their own 3D content to the Mars map to share with the world.

Today's announcement is the latest benefit from a Space Act Agreement NASA's Ames Research Center in Moffett Field, Calif., signed with Google in November 2006. Under its terms, NASA and Google agreed to collaborate to make NASA's data sets available to the world.

NASA Ames, along with its partners at Google, Carnegie Mellon University, SETI, and other institutions, helped produce the data to make this possible.

Google's innovative search technologies connect millions of people around the world with information every day. Google is headquartered close to Ames in Silicon Valley with offices throughout the Americas, Europe and Asia.

Meteor Explosion in Bone Indonesia

Astronomers revealed that a large explosion occurred in the waters of the Gulf of Bone, South Sulawesi Indonesia on October 8, 2009 is the result of a meteorite falling to earth from an asteroid about 10 meters in diameter.

"The explosion occurred due to atmospheric ressure causes the release of considerable energy, where the meteorite fall rate of about 20.3 km per second or 3,080 km per hour," said astronomers from the institute of Aviation and Space Agency (Lapan) Dr Thomas Djamaluddin in Jakarta , Tuesday (27/10).

International monitoring system to ban nuclear testing from 11 stations, reported having detected a large explosion that centered around the latitude and longitude 4.5 LS 120 BT, around 11:00 am on October 8. Blast analysis showed that the explosive force of about 50 kilotons of TNT (Trinitrotoluene) and signals the explosion which also reached the high stratosphere more than 20 km.

Meteor explosion in Bone, South Sulawesi, on October 8 and worldwide scientific attention. The explosion triggered a large asteroid was even reported to be detected by the alarm's infrasound Comprehensive Nuclear Test Ban Treaty Organization (CNTBTO), a distance of 10,000 km from the location of the meteorite fall.

As reported Spaceweather.com, a large explosion in the collapse of Bone confirmed asteroid 10 meters in diameter. Power of the explosion, according to researchers from the University of Western Ontario, Elizabeth Silber and Peter Brown, equivalent to 50 kilotons of TNT bombs. Or, two to three times more powerful than the atomic bomb blast that occurred in World War II.

To the point, this explosion was detected by the sensor that is dedicated CNTBTO detect the activity or nuclear explosion on earth. The explosion was very surprised astronomers world. Because, they did not detect the existence of this asteroid before digging the earth.

Most asteroids that fell did not cause damage on Earth, but its diameter reaches more than 25 meters. Djamal say, based on the estimated distribution of meteoroids, asteroids in the space near Earth, such objects have probably fallen on the earth every 2 to 12 years.

On Thursday (8 / 10), citizen Bone, South Sulawesi, were startled by the sound of the explosion in which several witnesses had seen the object emits fire and smoke in the air.

Robot Mimics Both Humans and Monkeys

improving the brain machine interface so that robots understand human intentions is essential in expanding practical applications of robots. The main trend in BMI has been to transmit information from the human brain to the robot’s computer, but the research group of Dr. Mitsuo Kawato, director of the Computational Neuroscience Laboratories at the Advanced Telecommunications Research Institute International (ATR), has developed a robot that can learn by imitating humans.

This robot is the CBi, a humanoid robot with a height of 155 cm and weight of 85 kg. Kawato and his colleagues have conducted many studies on reproducing brain activity in computers. The result of their accumulated research was the successful development of a computer system that, when a constant movement is repeated, automatically programs that movement so that it can be reproduced. When a human takes the CBi’s arm or leg and teaches it how to move, this system on the CBi enables it to automatically learn that movement. It is thus imitating human activity.
Controlling a robot today generally requires expert knowledge, making it virtually impossible for ordinary people to operate robots. With advances in the system developed by Kawato, however, general users will be able to control robots, and this could serve to accelerate the spread of their use.
The CBi has already learned such high-level movements as using a bat to hit a ball thrown by a human, and rolling a ball on its palm. Viewers were amazed with a public demonstration in January 2009 of the CBi hitting a thrown ball.
Flexible joints are another characteristic of the CBi. Gear mechanisms are used in most robot joints, but the CBi’s main joints use hydraulic cylinders. This enables smoother and more human-like movements than in conventional robots. The CBi is also equipped with high-level posture control with the use of a three-axis gyroscope and acceleration sensor, so that it keeps its feet and does not fall over easily even when pushed or shaken by humans.
The CBi is also at the leading edge of BMIs in which the computer understands brain activity. Its abilities were demonstrated in January 2008 when it showed that it could imitate a monkey. In a joint experiment between ATR and Duke University in the United States, Duke Professor Miguel Nicolelis and colleagues had a monkey walk on a treadmill, and then data of the monkey’s brain activity was sent in almost real time over the Internet to the CBi in Kawato’s laboratory. The CBi understood the movements of the monkey based on such data and walked in a similar way. When the movements of the CBi were displayed in front of the monkey walking on the treadmill, the monkey seemed to match its pace to that of the CBi, Nicolelis reported. The results of this experiment were viewed as a successful example of interactive BMI. (Keiichi Maeda)

MOUNT KILIMANJARO HISTORY

Kilimanjaro, with its three volcanic cones, Kibo, Mawenzi, and Shira, is an inactive stratovolcano in north-eastern Tanzania rising 4,600 m (15,092 ft) from its base (and approximately 5,100 m/16,732 ft from the plains near Moshi), and is additionally the highest peak in Africa at 5,892 metres (19,331 ft), providing a dramatic view of the surrounding plains.

Mount Kilimanjaro was formed during the most recent faulting of the Rift valley two to three million years ago, an event that also led to the formation of Mount Kenya. Kilimanjaro was certainly an active volcano 100,000 years ago when the the crater below Kibo Peak was formed. The glaciers around the peak probably began to form some 11,700 years ago. However, it is thought that due to global warming they will have melted within another 20 years.
It is possible that the snow-capped Mountains of the Moon described the Greek geographer, Ptolemy, in the second century AD referred to Mount Kilimanjaro. In the sixth century Chinese sailors returned home with tales of a great inland mountain, but Kilimanjaro remained something of an enigmatic legend to non-Africans well into the nineteenth century.
In 1848, the German missionary, Johannes Rebmann, while venturing inland in a bid to convert the tribes to Christianity, sighted the snow-capped mountain from Tsavo but his report was met with ridicule until 1861 when Dr Otto Kersten and Baron Karl Klaus von der Decken scaled the mountain to a height of 4300 metres. The first Europeans to reach the summit were Hans Meyer and Ludwig Purtscheller in 1889. Mawenzi peak was first climbed in 1912.
The mountain has retained a legendary and almost mystical aura throughout the twentieth century. In 1938 Ernest Hemingway enhanced this when he wrote his classic novel, The Snows of Kilimanjaro. On 1st January 2000, a thousand people watched the first sunrise of the new millennium from the peak.
