A revolution is in the offing for deaf and dumb with scientists testing a new mobile device which they claim will transmit American Sign Language over cellular networks. The tool, which can be integrated to any high-end mobile phone with a video camera. The engineers are now working to optimize compressed video signals for sign language, increasing the quality of images around the face and hands to reduce data rates to 30 kilobytes per second. To minimize the amount of battery power, the MobileASL phoners employ motion sensors to determine whether sign language is being used. This system could be integrated with the iphone 4, the HTC Evo, or any device that has a video camera on the same side as the screen.
Japanese gadget Manufacturer Company has come up with the new mini cooker called ‘Dryer Box’ which saves your phone from going kaput. Just heat the mobile phone in this mini cooker and all the moisture content will be absorbed by the cooker. The cost of this device is $12. If they fail to rescue the device after thirty minutes, there is no charge. In the meantime, dropping their wet phone into a bag of rice to absorb moisture is a good idea.
The US scientists have developed a new computer programme that can automatically translate an ancient language into a known language. This discovery would hope to help them decipher some of the scripts that they are yet to understand. This programme so far as decoded successfully the over three thousand year old Ugaritic language. This system is able to make assumptions about the way different words are formed and whether they consist of a prefix and a suffix. Through repeated analysis, the program linked letters and words to map nearly all Uragritic symbols to their Hebrew equivalent in matter of hours.
Want to stop your child from watching adult TV programmes in your absence? Let a new remote do the work for you. Scientists have developed the new TV remote fitted with sensors which can identify individual family members offering personalized viewing options and restrictions. The normal TV remote is modified to design a new remote with sensors to measure the way it was held as volunteers channel-surfed.
A Hebrew University student has showed that an electric battery based on boiled potatoes could provide a cheap source of electricity in the developing world. The treated potato battery generates energy that is five to 50 times cheaper than commercial batteries. A light powered by the battery is at least six times more economical than kerosene lamps often used in developing world. The student discovered a new way to construct an efficient battery using zinc and copper electrodes and a slice of an ordinary potato. Boiling the potato prior to use in electrolysis increased electric power up to 10-fold over the untreated potato and enabled the battery to work for days and even weeks.
A semaphore in computer science is a classic way of protecting shared resources. In multi-programming environments like Unix systems, semaphores are a technique for coordinating or synchronizing activities in which multiple processes compete for the same operating system resources. A process needing the resource checks the semaphore to determine the resource’s status and then decides how to proceed. Depending on the value found, the process can use the resource or will find that it is already in use and must wait for some time before trying again, thus avoiding deadlocks.
Each galaxy has billions of stars. Such galaxies are not uniformly spaced in the universe but exist in the groups and clusters; a group containing up to 40-50 galaxies and clusters containing about thousands of galaxies. These groups and clusters along with isolated galaxies may form larger clusters known as galactic superclusters. These are the largest structures of matter found in the universe. Our galaxy, Milky Way, is a member of a local group of galaxies, which is in turn a part of the Virgo supercluster.
The random changes in gene frequencies occurring by chance and not under the control of natural selection are called genetic drift or random genetic drift or sampling error. This theory was advocated by Sewall Wright in 1930. It explains the change in gene frequency and hence evolution. It is caused due to sampling error. A new generation arises from a sample of sex cells randomly taken from the gene pool (or gametes) of preceding generation. Now, when a sample is drawn in a large population randomly, chances that the sample will contain nearly the same gene frequency that is present in the gene pool are very high. However, in a small population, chances that the sample drawn at random will contain an altered gene frequency are very high.
Electromagnetic waves which exist only in the vacuum of empty space constitute an ocean of infinite energy called scalar energy. These new waves of energy are called longitudinal electromagnetism to distinguish from transverse electromagnetism. A scalar pendant is the therapy pendant, also known as chi therapy pendant or heat therapy pendant. It emits far infra-red and produces high levels of negative ions. Although negative energy dissipates quickly in the open air, wearing a scalar pendant next to the skin enables the body to absorb them. These pendants neutralize or reduce the negative effects of electromagnetic radiation from cell phones and other electrical appliances used daily.
Baryogenesis is a branch of physics concerned with how the baryons were originally formed. Baryons are a family of subatomic particles and like some other subatomic particles has their opposite category called anti-baryons. Interestingly baryons outnumber anti-baryons thus giving rise to a lot of residual matter in the universe. Physicists believe the asymmetry between baryons and anti-baryons must have been caused by an unknown phenomenon in the early stages of the universe.
