‘Nanoresonators’ Might Improve Cell Phone Performance

:: ‘Nanoresonators’ Might Improve Cell Phone Performance ::

                                 Researchers have learned how to mass produce tiny mechanical devices that could help cell phone users avoid the nuisance of dropped calls and slow downloads. The devices are designed to ease congestion over the airwaves to improve the performance of cell phones and other portable devices.
                                 “There is not enough radio spectrum to account for everybody’s handheld portable device,” said Jeffrey Rhoads, an associate professor of mechanical engineering at Purdue University.

             This image from a scanningelectron microscope shows a tiny mechanical device, an electrostatically actuated nanoresonator, that might ease congestion over the airwaves to improve the performance of cell phones and other portable devices.
              The overcrowding results in dropped calls, busy signals, degraded call quality and slower downloads. To counter the problem, industry is trying to build systems that operate with more sharply defined channels so that more of them can fit within the available bandwidth.

                   “To do that you need more precise filters for cell phones and other radio devices, systems that reject noise and allow signals only near a given frequency to pass,” said Saeed Mohammadi, an associate professor of electrical and computer engineering who is working with Rhoads, doctoral student Hossein Pajouhi and other researchers.

                      The Purdue team has created devices called nanoelectromechanical resonators, which contain a tiny beam of silicon that vibrates when voltage is applied. Researchers have shown that the new devices are produced with a nearly 100 percent yield, meaning nearly all of the devices created on silicon wafers were found to function properly.
“We are not inventing a new technology, we are making them using a process that’s amenable to large-scale fabrication, which overcomes one of the biggest obstacles to the widespread commercial use of these devices,” Rhoads said.

                       Findings are detailed in a research paper appearing online in the journal IEEE Transactions on Nanotechnology. The paper was written by doctoral students Lin Yu and Pajouhi, Rhoads, Mohammadi, and graduate student Molly Nelis.

Airtel sms trick, send 100 free sms just for 3 rs.

                This is not a free sms trick. But for heavy messagers this is almost like free sms. Actually this is an offer from airtel itself and any one can activate this trick by simply sending an ussd code. This is a free sms pack from airtel which is really very cheap. It costs just 3 rs for 100 sms per day. Doesn’t it sound cool. There is no question about this trick works or not as it is an active offer from airtel. We are posting it here because many of the airtel users are unaware of this trick. There is no daily rental to activate this plan. There is a one time charge for three months. The pack costs 5 rs for 6 moths. Once you activate this free sms pack first three sms of each day will be charged at rs 3 per each sms message you send. and after that you can send free 100 sms messages to anywhere in India. So this plan gives free benefits for airtel subscribers who use sms heavily. And the very best thing is that both local and national message are free.

How to activate airtel free sms pack.

                Follow the instructions shown below to activate free sms pack on airtel. You will be charged one time rs for 3 months and your first three sms will be charged too.
  • dial *555*5#
  • you will get the confirmation message for activating free daily sms pack from airtel
  • 5rs will be deducted from your balance and the pack is active for 180 days.
  • first 3 sms will be charged at rs 1 if its local and rs1.50 if its national
  • every local and national sms from theron till the midnight will be free until you ouch the 100 sms mark
                 So that was all about the free sms offer from airtel. We bet most of the airtel subscribers didnt knew about this trick.

IBM Says Practical Quantum Computers are Close

:: IBM researchers claim they are now close to have access to basic technologies that would allow them to build a "minimum" quantum computer. ::



                                             According to the company, scientists have found ways to retain the integrity of quantum bits (qubits) and reduce computation errors as a result. The solution appear to be superconducting qubits that are constructed via traditional silicon fabrication techniques and hold the potential to scale up to potentially thousands or millions of qubits one day.
"The quantum computing work we are doing shows it is no longer just a brute force physics experiment. It's time to start creating systems based on this science that will take computing to a new frontier," said IBM scientist Matthias Steffen, who manages the IBM Research team that works on quantum computing systems. The vision of quantum computing is to enable computers to do "millions of computations at once" with a single qubit. According to IBM, a 250-qubit system "contains more bits of information than there are atoms in the universe." In contrast to a traditional bit, which can either have the value "0" or "1", a qubit can have "0", "1" and both values at the same time.
                      While there is a clear vision to build a quantum computer, scientists are dealing with a number of substantial roadblocks to realize such a device. One key problem remain interference factors that influence the controllability and reliability of qubits, such as temperature, electromagnetism and material defects. IBM said that the transition to a “three dimensional” superconducting qubit (3D qubit) allowed them to extend the time a qubit retains its state to 100 microseconds, which is a 2 to 4x improvement over previous results. It is not eternity, but IBM says the value " reaches just past the minimum threshold to enable effective error correction schemes and suggests that scientists can begin to focus on broader engineering aspects for scalability." The company has built a 3D qubit device with a 1mm qubit as part of a Sapphire chip to demonstrate its research progress.
                       IBM said that it believes that, in the future, a "classical" computer system will integrate quantum computing hardware to form a functional quantum computing system. The next challenges to achieve this goal will be necessary advances in communications and packaging technology.
