© 2010 PhysOrg.com Citation: Plan to use submarines to subdue typhoons/hurricanes (2010, September 30) retrieved 18 August 2019 from https://phys.org/news/2010-09-submarines-subdue-typhoonshurricanes.html (PhysOrg.com) — A Japanese hydraulic manufacturing company has unveiled plans to use submarines to downgrade the force of typhoons. The company, Ise Kogyo, from Mie in Central Japan, has had patents approved in Japan and India for its geo-engineering plan to use submarines to subdue typhoons, which are known elsewhere in the world as hurricanes, tropical storms, cyclonic storms and cyclones.

The idea is to use a fleet of around 20 submarines in front of the gathering storm, each fitted with eight pumps capable of shooting 480 tonnes of cold water a minute. The submarines would dive to a depth of 30 meters and pump water from that depth onto the surface of the sea to lower the surface temperature. Company executive Koichi Kitamura, who came up with the idea, said that in an hour a fleet of 20 submarines could lower the temperature of 57,000 square meters of surface water enough to diminish the strength of the typhoon, which needs an ocean temperature of 25 to 27 degrees Celsius to form and keep spinning. He said the scheme should be able to stop a typhoon in its tracks.A patent application for the scheme is pending and may be approved soon in the US. The main problems in its implementation would seem to be accurately predicting the path of the storm and deploying enough submarines to exactly the right place in time. These problems may prove insurmountable, and questions have also been raised on the advisability of preventing such storms anyway, since they provide a critical heat transport mechanism for transferring thermal energy around the globe.Ise Kogyo is now reportedly seeking partners to help them test their ideas.

In a game of one-upmanship, a Chinese team of physicists has figured out how to entangle eight photons simultaneously and to observe them in action; the previous record was six. In a paper published in arXiv, the team from the University of Science and Technology of China in Hefei, describe how they were able to convert a single photon into two entangled photons, using a nonlinear crystal, and then how they repeated that process with one of the paired photons produced, while holding the other in place, producing another pair, and then did it repeatedly until they had eight photons all entangled together, all held in place and all observable for a period of time. Quantum electronics: Two photons and chips © 2010 PhysOrg.com First predicted by Einstein, in conjunction with two other physicists, Boris Podolsky and Nathan Rosen, entanglement (from the German word Verschränkungis) is where particles exist in a relationship so closely related, that anything that happens to one, somehow automatically happens to the other, like identical twins both feeling a pin-prick on their finger tips, whether in the same room, or miles apart.In the new experiment, the researchers fired a photon from a high energy laser through a nonlinear crystal, causing it to become a pair of weaker entangled photons. They then kept one of the pair aside while the other was sent through another nonlinear crystal, producing another pair of entangled photons that were also still entangled with the original pair. They then held back one of the new pair while sending its twin through another nonlinear crystal, forming yet another pair of entangled photons that was also entangled with all the other entangled photons, and then repeated the procedure until they had a total of eight photons, all of which were entangled together.After several years of research, physicists have learned a lot about creating entangled particles; what they haven’t been able to do is pin them down. Entangled particles, such as the photons produced in the Chinese experiment don’t generally last long, which makes this experiment all the more exciting because it means the researchers were able to coax the entangled photons into hanging around long enough to be observed while the new entangled particles were coming into existence.Many physicists have likened the whole process to the infamous thought experiment so named, Schrödinger’s cat, due to the letter written by physicist Erwin Schrödinger to Einstein where he described a cat hidden in a box with a radioactive substance that may or may not have decayed to the point of discharging a poisonous substance that when released would kill the cat, which leads to the mind state of a cat existing that is simultaneously both dead and alive.The ultimate goal in studying entangled particles is to figure out how they operate and then how to put them to use in such devices as quantum computers.

(PhysOrg.com) — Micro-Star International (MSI) revealed voice control via motherboard at the Intel Developer Conference. The MSI demo showed how its add-on PCIe x1 card can add voice control to selected Sandy Bridge motherboards that feature the JDLED3 connector. MSI voice software that is part of this approach is called Voice Genie. The Voice Genie software can be used to set up reliable recognition of the user’s voice and can set up the actual voice commands to perform tasks.

Citation: MSI shows voice-controlled motherboard approach at IDF (2011, September 19) retrieved 18 August 2019 from https://phys.org/news/2011-09-msi-voice-controlled-motherboard-approach-idf.html The software tracks the user’s voice patterns so that control functions can be set in motion. The result of the MSI voice-activated-motherboard approach is that a user can instruct the PC to turn on or turn off just by saying certain words.Theo Valich of Bright Side of News provided one example of an MSI voice-control setup, if using the MSI Big Bang motherboard: To get the PC up and running, the user says ‘MSI Big Bang Power On,’ and to shut it down the user goes into reverse, to say ‘Power Off MSI Big Bang’ but one can always customixze the commands. The only restriction in coming up with a customized instruction is to keep the reverse structure of phrasings for your “on” and “off” (Big Bang…On, Power Off…Bang).The price for the add-on and a release date were not yet available, though MSI said the voice-control module would be more than affordable. MSI has actually been working on its voice-activated motherboard technology for several years, according to reports. MSI, a leading motherboard and graphics card manufacturer, is not the first to innovate voice-command functions for PCs. Microsoft has done substantial work with speech recognition. Windows carries speech recognition and there is much talk about how Windows 8 will recognize various speech commands. Tellme, the speech technology corps at Microsoft, is working with other Microsoft teams to push the advancement of speech recognition further. Nonetheless, what is special about the MSI approach is that is takes voice control beyond the operating system. In addition to the voice control demo, MSI unveiled a lineup of new motherboards at the IDF event.The three newcomers are based on the X79 chipset.

Ever since hard drives were invented, scientists have been hard at work trying to figure out ways to make them smaller while at the same time developing ways to make them more dense so that they can hold more information. As the team at IBM notes, currently, it takes approximately 100,000 atoms to hold a single bit of information. If a technique could be found to commercialize their single-atom approach, they further note, it would allow for holding something as massive as Apple’s iTunes library of songs on something as small as a credit card.To create their tiny magnet, the team used a scanning tunneling microscope to manipulate holmium atoms placed on a magnesium oxide plate (to keep the magnetic poles stable). Applying an electric current to the microscope’s probe allowed for changing the magnetic orientation of the atom between two states, which, the team notes, could be used to represent on/off states for a single bit of data. To read the state, the team measured the magnetic current passing through the atom. The team notes also that the state of several atoms could be read or written when the atoms were as close as a single nanometer apart.IBM has been investing heavily in scanning tunneling microscope research for decades, a technology they have been credited with inventing (Gerd Binnig and Heinrich Rohrer won the Nobel Prize in physics for this accomplishment back in 1986). Recently, they also announced that they had developed a new technique that offered a better way to measure the magnetic field of individual atoms and in a somewhat related development, also announced that they would be offering the world’s first commercial “universal” quantum-computing service.

Back from the dead—how to revive a lost species More information: Ylenia Chiari et al. Self-righting potential and the evolution of shell shape in Galápagos tortoises, Scientific Reports (2017). DOI: 10.1038/s41598-017-15787-7AbstractSelf-righting, the capacity of an animal to self-turn after falling on its back, is a fitness-related trait. Delayed self-righting can result in loss of mating opportunities or death. Traits involved in self-righting may therefore be under selection. Galápagos giant tortoises have two main shell morphologies – saddleback and domed – that have been proposed to be adaptive. The more sloped shape on the sides of the shell and the longer extension of neck and legs of the saddlebacks could have evolved to optimize self-righting. The drier environments with more uneven surfaces where the saddleback tortoises occur increases their risk to fall on their back while walking. The ability to fast overturn could reduce the danger of dying. To test this hypothesis, we used 3D shell reconstructions of 89 Galápagos giant tortoises from three domed and two saddleback species to compare self-righting potential of the two shell morphotypes. Our results indicate that saddleback shells require higher energy input to self-right than domed ones. This suggests that several traits associated with the saddleback shell morphology could have evolved to facilitate self-righting. Studying the functional performances of fitness-related traits, as in this work, could provide important insight into the adaptive value of traits.

Noting that being unable to flip over is a leading cause of death of the tortoises, the group suggests the different shell types may have evolved to handle tipping under different environmental circumstances. (Phys.org)—A team of researchers with members from the U.S., Portugal and France has conducted a study of the amount of energy required by the two main types of tortoises that reside on the Galapagos Islands—the domed and the saddleback—to flip themselves right side up when they overturn. In their paper published in Scientific Reports, the group describes analyzing shells of the two tortoise types, comparing them and then calculating which required more energy to flip itself back upright. The giant tortoises that live on the Galapagos Islands are world famous due to their huge size. Less well known is that there are two main types defined by differently shaped shells: domed and saddleback. The domed species are the ones mostly seen in tourist pictures. Less popular are the saddleback, which have a shoehorn-shaped part of their shell near the neck, flatter shells and longer necks. Both kinds tend to tip over due to rough terrain or when fighting with one another. But which has to expend more energy to right itself? That is what the team on this new effort sought to find out.To figure out how much energy each type would have to expend in tipping itself back upright, the researchers studied the techniques used by both: The domed species tend to move their legs around until they work up enough momentum to turn over. The saddlebacks, on the other hand, used their necks in addition to flailing their legs. The group then took pictures of 89 of the shells (many from inside museums) to create 3-D versions on a computer. Then, at the Rotterdam Zoo, the team hoisted one of the turtles onto a platform connected to equipment that produced the desired result.
