#Why Bluetooth use is on the rise Bluetooth has been with us for around 15 years.

Named after Denmark's King Harald Bluetooth Blatand, who reigned in the 10th century AD, it is a technology that everyone is aware of on their computers and phones,

yet not many people choose to use. As a means of allowing devices to talk to each other cheaply and wirelessly over short distances,

it has tended to stay largely in the shadows, leaving the limelight to the technologies it connects.

Now however, with the rapid growth in the use of mobile and sensing technologies along with the release of an updated version of the system,

and predictable technology,#says Professor Roch Guerin, Chair of Computer science and Engineering at Washington University, St louis."Bluetooth targets lower transmission ranges and data rates than wi-fi,

Bluetooth Smart, launched in 2011, includes a smarter power management system that allows it to turn on,

transmit data and shut down more quickly#in just a few milliseconds in some cases. Depending on the devices being connected

and the data being transmitted, this updated system consumes anywhere between half and 1/100th of the power of the previous version.

As a result, machines using Bluetooth that previously ran for a few months on a coin cell battery,

"Bluetooth classic is for sending steady streams of voice and audio,#says Suke Jawanda, Chief Marketing Officer of the Bluetooth Special interest Group (SIG),

which owns and licenses Bluetooth technology.""Bluetooth Smart is about sending packets of bits and data to applications.#

#Life changinghealthcare is cited frequently as one area that hasn't witnessed the radical transformations underway elsewhere as a result of the ongoing digital mobile revolution.

The growth of novel personal medical sensing technologies, many of which use Bluetooth, could soon change this.

Earlier this year, a Silicon valley-based start-up called Scanadu sought to raise $100, 000 on the crowd-funding site Indiegogo.

In fact donors pledged over $1. 6 million, making it the most funded project in the site's history.

The product description may have helped: the Scanadu Scout is described perhaps best as something approaching a real version of the medical tricorder wielded by Star trek doctor Leonard"Bones#Mccoy.

This data is transmitted via Bluetooth to users'phones or tablets. With recent advances in technology such as Bluetooth, we are now able to build medical devices that weren't possible just a decade ago#.

#at an affordable price using existing infrastructure of smart phone telecoms#says Scanadu's CEO Walter de Brouwer."

"For people who live far from hospitals, in places like Africa, this could be life changing.#

once embedded under the skin monitors substances in the blood such as glucose and cholesterol so that chronic diseases like diabetes or the effects of treatments such as chemotherapy can be monitored.

The raw medical data, which is sent wirelessly via Bluetooth to an Android app, can be forwarded automatically to doctors.

Bluecell is still a few years from commercialisation.""We chose Bluetooth because of its wide distribution in consumer devices,

#says Jacopo Olivo, one of the researchers.""It's an interesting way that Bluetooth can interact with the biotech industry.#

#Other personal health sensors that use Bluetooth include the Cardiopad, an electrocardiography (ECG) machine developed to monitor heart activity in patients in remote areas of Cameroon,

and Monobaby, a device being developed to prevent Sudden infant death syndrome, also known as cot death, using an accelerometer attached to baby clothing.

and sends that information directly to an ipad app via Bluetooth. By cross-checking this data against a database

the app provides information about the health of plants, when and how much to water them,

Sensors could be linked via Bluetooth to sprinkler systems to automatically optimise moisture levels. The ability to use just the right amounts of water and fertiliser to produce a good harvest without wasting resources can improve crop yields and rural incomes.

Bluetooth is also being used to help those in agriculture in other ways. Kenyan mobile tech company Virtual city has developed Agrimanagr

an app designed to speed up and automate the flow of information and reduce costs for farming businesses.

electronic scales are used to transmit the weight of produce via Bluetooth to a mobile phone which records this in farmers'accounts on a cloud-based server.

#says Virtual city chief executive John Waibochi.""Buyers would tamper with the weight scale.##Going digital and printing receipts"cuts out fraud#and increases the value to farmers 9-13%,#he adds.#

#This system could of course be done without Bluetooth, but being wireless makes it easier.""Out in the rural areas,

cables would not survive,#claims Waibochi.""And I need my devices to go to sleep immediately after they are used.

With Bluetooth, our devices do that, and can work for 12 hours without electricity.##Bluetooth can also provide new ways of communicating in rural settings where internet access is unavailable or out of reach for the poor.

Gary Marsden, a computer scientist at the University of Cape town, developed Big board, an electronic notice board that disseminates information wirelessly and for free.

The system displays a series of icons representing information on various topics on a screen.

Users take a picture of an icon they are interested in with their phone and send it via Bluetooth to a nearby device which sends them the information they want.

Files can be pictures text, video or audio. Potential applications include distributing information on health, job offers or entertainment.

In a pilot project Big board was used to inform voters about the manifestos of politicians standing in the 2007 Kenyan presidential election.

He also developed Com-Me, a collection of hardware and software components to help people with limited access to electricity

and the internet create and share content. This includes a solar-powered phone charging station and a Bluetooth-based local version of Dropbox

designed to allow off-grid communities to share and store information in a variety of formats.

Bluetooth Smart, like its older sibling, may be a relatively straightforward radio wave-based transmission technology. But as we devise more and more ways to benefit from ever greater connectivity between the people, other living organisms, objects and our environments,

it seems to be getting smarter by the day. If you would like to comment on this article

the AMST project is developing a new generation of software. AMST stands for Advanced Multi-physics Simulation Technology, a type of software that can be used for a wide range of such complex processes.

Besides its versatile use, the software main advantage is its independence from any experimental conditions. Despite this, it has proven its ability to predict very detailed results.

Scientists and engineers then analyse the data obtained in great detail in order to unveil the underlying physics of the processes Involved with these theoretical insights complementing the empirical knowledge our understanding of multi-physics has been broadened considerably.

From here, many different application domains are encountered. A first investigation deals with gasification of wood. The predicted results include both the pyrolysis process of individual particles and the tar concentration in the gas as a response to the interaction between hot air and wood particles.

and data collected by the sensors is sent wirelessly to a receiver. A number of battery-free technologies exist that are powered by solar and ambient radio frequency waves.

The researchers say this technology would be useful in places where sun and radio waves can t always penetrate such as inside walls

or bridges and below ground where there might be at least small temperature fluctuations. For instance the device could be placed in an attic

and send data wirelessly to a receiver 5 meters away. That means any slight shift in an office building s air conditioning or the natural outside air temperature during the course of a day would be more than enough to activate the chemical in the bellows.

#Computer gets smarter by looking at online pics 24-7 Carnegie mellon University Posted by Byron Spice-Carnegie mellon on November 26 2013a computer program called the Never Ending Image Learner (NEIL) is running 24

hours a day searching the internet for images and doing its best to understand them on its own.

As NEIL s visual database grows the computer program gains common sense on a massive scale. NEIL leverages recent advances in computer vision that enable computer programs to identify

and label objects in images to characterize scenes and to recognize attributes such as colors lighting and materials all with a minimum of human supervision.

In turn the data it generates will further enhance the ability of computers to understand the visual world

and with NEIL we hope that computers will do so as well. computer cluster has been running the NEIL program

since late July and already has analyzed three million images identifying 1500 types of objects in half a million images and 1200 types of scenes in hundreds of thousands of images.

and catalogued. hat we have learned in the last 5 to 10 years of computer vision research is that the more data you have the better computer vision becomesgupta says.

Some projects such as Imagenet and Visipedia have tried to compile this structured data with human assistance.

But the scale of the Internet is so vast##Facebook alone holds more than 200 billion images that the only hope to analyze it all is to teach computers to do it largely by themselves.

A Google Image search for instance might convince NEIL that inkis just the name of a singer rather than a color. eople don t always know how or

what to teach computershe says. ut humans are good at telling computers when they are wrong. eople also tell NEIL what categories of objects scenes etc. to search

It can be anticipated for instance that a search for pplemight return images of fruit as well as laptop computers.

The program runs on two clusters of computers that include 200 processing cores. The Office of Naval Research and Google Inc. support the project.

The research team will present its findings on Dec 4 at the IEEE International Conference on Computer Vision in Sydney Australiasource:

#FLOW-AID helps farmers save water without sacrificing yields Wee already seen gadgets such as Koubachi and Flower power,

Using their smartphone, a farmer can access their network of FLOW-AIDS over the internet,

to check the moisture and nutrient levels of their soil. The system will notify them

which point they can start their irrigation system remotely via their phone. As soon as they see that sufficient moisture levels have been restored

they can use their phone to turn the irrigation back off. The system also incorporates software that takes location-specific factors such as plant properties,

soil characteristics and water rationing limits into account. So far FLOW-AID has been tested in six countries,
