Mobile Devices, the Cloud, and their Effect on Next Generation Measurement Systems

Mobile Devices, the Cloud, and their Effect on Next Generation Measurement Systems: The proliferation of mobile devices and the explosion of ubiquitous computing networks have changed the world in which we live. This webcast will discuss these trends and their effect on the data acquisition industry.

BIO-COMPUTERS

Scientists have developed a “biological computer” capable of deciphering images encrypted on DNA chips. As a proof of concept, the scientists encrypted the Scripps Research and Technion logos on a single DNA chip and, using software, decrypted the separate fluorescent images.

“Our biological computing device is based on the 75-year-old design by the English mathematician, cryptanalyst, and computer scientist Alan Turing,” Keinan said. “He was highly influential in the development of computer science, providing a formalization of the concepts of algorithm and computation, and he played a significant role in the creation of the modern computer. Turing showed convincingly that using this model you can do all the calculations in the world. The input of the Turing machine is a long tape containing a series of symbols and letters, which is reminiscent of a DNA string. A reading head runs from one letter to another, and on each station it does four actions: 1) reading the letter; 2) replacing that letter with another letter; 3) changing its internal state; and 4) moving to next position. A table of instructions, known as the transitional rules, or software, dictates these actions. Our device is based on the model of a finite state automaton, which is a simplified version of the Turing machine. “

The first author of the study, “A Molecular Cryptosystem for Images by DNA Computing,” is graduate student Sivan Shoshani of Technion. In addition to Keinan and Shoshani, authors include postdoctoral fellow Ron Piran of Scripps Research and Yoav Arava of the Technion.

SENSOR FARMING

SENSOR SOFTWARE FOR FARMERS TO GET THE PRE-KNOWLEDGE ABOUT THE UPCOMING INFECTION.
Now farmers are also get benefit from computer software named as sensor software,the farmer will use this on his field and get prediction about the upcoming danger of pests .
by this software farmer will get the idea how much he need pesticides or other necessary elements
for his crop.

Prof Roy Kennedy, director of the National Pollen and Aerobiology Research Unit (NPARU) based at Worcester University, led the development of the technology, which was funded by the Department of Environment, Farming and Rural Affairs (DEFRA).

‘The device is very similar to a pregnancy test but it’s set up to detect important plant pathogens. It’s semi-quantitative in that you can put the test device into a digital reader and look at the reading in relation to a calibration curve, which tells you how many propagules [active spores] are in the air.’

Kennedy added that early warning of infection means that farmers no longer have to waste time and money spraying crops when there is no disease in the air — resulting in more targeted protection with potentially greater yields.

‘We have several of these devices each set up for different pathogens that affect different crops in the UK — and we’re looking to detect these in the air before they infect the crop.’

The system is being tested out by several agriculture consultancies, including the Allium and Brassica Centre (ABC) in Lincolnshire, and Alphagrow in Lancashire.
