For the moment, the processing of data carried by optical signals is limited by the speed with which the optical signal can be interpreted. If you could slow down could properly the signal, more information could be processed without overloading the system.
That goal is closer thanks to the work of Qiaoqiang Gan, electronics engineer at the University at Buffalo (State University of New York), and colleagues at Lehigh University. Nanoplasmonics structures they have created through the technique of nano-sized cracks in metal surfaces at different depths, which alters the optical properties of materials.

The art industrial vacuum cleaners are designed for large cleaning operations. These machines are not only used for cleaning, but also for the cleanup of sites in an enclosure. They are equipped with filtration system reliably resistant to wastes and substances to be sucked. These industrial vacuum cleaners are composed of a shell styling, engine and a filtering device associated with a collection tank. You can visit here for available information about sandpiper pumps.
Industrial vacuum cleaners can be equipped with three different engine types. They may be single-phase carbon, pneumatic or three phase. The vacuum filter must be able to retain all dust particles. For treatment of areas with high pollution, the filters are static. The tanks used to contain solid waste, liquid, dusty, muddy or greasy. Industrial vacuum cleaner in good working condition must aspire for at least 5 hours straight 7 days on 7. Not only must he have high power and great speed, but also an ability to separate the waste liquids from solids. It must also absorb the elements of high temperature microphones. The industrial vacuum cleaner should be able to cover so repetitive and slow to clean surfaces. If you need more information about industrial dispensing, you can visit here where you find all the necessary information.

This is the first study of its kind, researchers have found that portable communication devices, such as Smartphones, are not doing that people stop using media such as newspapers or television.
Instead, these portable communication devices themselves fill the spaces of people’s daily routine in which other means are not available or are not comfortable to get.
This suggests that the use of portable communications is growing in popularity by a different route to that followed in their day technologies like television.
In general, new media compete with old media and moving to some extent, as television did to radio, but not eradicated. Read the rest of this entry »
Future surgeons may use a system capable of recognizing the hand gestures as well as orders to control a robotic nurse or a computer to display images of the patient during medical surgery.
The recognition of hand gestures by robotic systems in the operating room may help reduce the duration of operations and the risk of infection. So believes Juan Pablo Wachs, professor of industrial engineering at Purdue University, USA.
The technology of visual recognition of hand gestures could have other applications, including the coordination of activities in response to emergencies arising from a catastrophe. Read the rest of this entry »
Engineering researchers at the University of Michigan imitated the structure of the antennae of the silkworm moth in the construction of a nanopore better, a little instrument in the shape of a tunnel that could expand knowledge about a class of neurodegenerative diseases including Alzheimer’s disease.
The nanopores, which are essentially holes drilled in a silicon chip, are tiny measuring instruments that allow the study of individual molecules or proteins. But even the best current nanopores clog easily, so the technology has not been widely adopted in laboratories. It is expected that improved versions bring a major advance toward faster and cheaper sequencing of deoxyribonucleic acid (DNA).
The UM team, led by Michael Mayer, Associate Professor, Departments of Biomedical Engineering and Chemical Engineering, wrote an oily coating that traps the molecules of interest and facilitates their transport through the nanopores. It also allows researchers to adjust the pore size with almost atomic precision.
“This gives us a much better tool for the characterization of biomolecules,” said Mayer. “It gives us a more precise knowledge of their size, charge, shape and concentration and the speed with which they are composed. This could help in the diagnosis and a better understanding of what happens in a class of neurodegenerative diseases including the evils of Parkinson’s, Huntington’s and Alzheimer’s.” Read the rest of this entry »
Go forgetting the plasma, TFT or LED. An article in the journal Nature Photonics has released a full color display based on “nanocrystal quantum dots” that could give way to devices with higher resolution and lower power consumption than today.
Those responsible for the article, led by Choi Byoung Lyong, electrical engineer at Samsung Advanced Institute of Technology (Yongin, South Korea), have produced a full color screen of 10 inches, more efficient and brighter than other methods developed by teams of competition. According to Choi, the red pixels achieve a 50% better brightness and 70% better energy efficiency. The display can also bend or curl.
The first devices to benefit from this technology within three years, could be mobile phones, according to Seth Coe-Sullivan , CTO of QD Vision, a U.S. company that produces lighting devices based on this technology. Read the rest of this entry »
When investing in real research note, and if not tell that to the control and safety systems. After the controversial body scanner, now comes AIRprint, a system capable of detecting the fingerprints of up to two meters away, according to an article published in the Technology Review at MIT.
Those responsible, the company Advanced Optical Systems (AOS), based in Huntsville, Alabama (USA) indicate that this prototype works by sending polarized light to the hand of a person and analyzing the reflection with two cameras configured to detect different polarizations.
Despite its small size, something smaller than a square tissue box, AIRprint houses two 1.3 megapixel cameras and a source of polarized light. One of the chambers receives horizontally polarized light and the other vertically. By separating the two polarizations, the device superimposed images to produce an accurate fingerprint, which is sent to a computer for verification. Read the rest of this entry »

You do not need complex computer virus or that the phones are the latest generation: a simple text message (SMS) is able to block any mobile phone, according to the Technology Review publication.
To do this, the SMS includes a small program called “binary”, capable of running on any phone, even low-end. This has been demonstrated at a security conference held in Germany two researchers, Collin Mulliner, a doctoral student, and Nico Golde, an undergraduate student, both from the Department of Homeland Security in Telecommunications from the Technical University of Berlin.
In particular, Mulliner and Golde were able to suddenly turn off and disconnect network from the several phones Nokia, LG, Samsung, Motorola, Sony Ericsson, and Micromax, an Indian manufacturer of popular mobile phones.
Each platform requires a specific malicious SMS to work, but according to two researchers, it would be easy to make an attack on a large number of phones by sending a set of five messages focused on the five most popular models, each device in a specific network. Read the rest of this entry »
Scientists know that the good wishes to meet them in the future are easy to do because they are distant, but when it comes not so. If you are someone who will make promises for the new year and would like to meet them, technology can help, as highlighted in Technology Review, Massachusetts Institute of Technology (MIT).
One motivation is money. On the web StickK.com its users down a specific goal and commit to losing a sum of money if you do not. You can also impose “anti-awards”: a big fan of Barca can be forced to buy a shirt of Real Madrid if he fails the objective.
But what seems more motivating, according to its creator, Ian Ayres, an economist at the behavior of Yale University, is being held to account. Users may appoint referees to monitor your progress and make a public challenge. Ayres says the website has more than 50,000 users after three years running, they have about 5 million dollars at risk. The success rate is between 70 and 80%. Read the rest of this entry »
