Mud Fueled Smart Sensors for the Bottom of the Ocean

ghIf you put tiny electrodes in the mud on the ocean floor, you can harvest enough energy to power a tiny sensor platform that can monitor what’s going on at those depths.

So say researchers from the University of Michigan at Ann Arbor, in a recent issue of IEEE Transactions on Circuits and Systems I. Together with collaborators from Korea and California, they have designed a self-sustaining sensor platform for oceanic sensing applications that is powered entirely by small-scale benthic microbial fuel cells.

“We wanted a platform that could run off very small harvesting sources,” Michigan electrical engineering professor and IEEE Fellow David Blaauw tells IEEE Spectrum. “If you can get power consumption down enough, there are all sorts of things you can use. Even plants produce little bits of voltage,” he says.

When benthic bacteria are in an anaerobic environment, their metabolism produces electric current. “It’s been well studied,” says Blaauw, “but in the past, people have struggled to get enough current to run something.”

 According to Blaauw, laboratory experiments confirmed that if a microbial fuel cell sits in the sediment, with the cathode floating in a water column

Car Camera Network Could Produce Virtual Maps of Pedestrians

poiA growing fleet of smart cars may add their street camera views to those of the surveillance camera networks already covering many major cities. That could open the door for a new technology that enables different video cameras to “talk” with one another and track the same individual person across many different camera views—possibly giving rise to Google Earth style maps that can display pedestrian and vehicle traffic.

The technology is based on a computer algorithm that can compare different camera views of the same person and learn to recognize the same individuals across many camera views by focusing on body color, texture and movement. Researchers envision a large-scale version of the system tracking pedestrian traffic on a virtual map—perhaps displayed on a car’s GPS screen—or enabling police to easily track fleeing suspects across multiple surveillance camera views.

“Our idea is to enable the dynamic visualization of the realistic situation of humans walking on the road and sidewalks, so eventually people can see the animated version of the real-time dynamics of city streets on a platform like Google Earth,” said Jenq-Neng Hwang, a professor of electrical engineering at the University of Washington, in a news release.

Metasurface Optics for Better Cellphone Cameras and 3D Displays

gfEngineers at the California Institute of Technology have created a metasurface out of tiny pillars of silicon that act as waveguides for light. The way they arrange the pillars allows them to control the phase of light passing through the surface; this ability gives them control over how the light is focused, as well as its polarization, which is important for uses such as liquid crystal displays and 3-D glasses. Metasurfaces are structured planes so thin that they count as being two-dimensional; their periodic designs manipulate light in unusual ways.

“We’re trying to create kind of a new platform for optics,” says Amir Arbabi, a postdoc in Andrei Faraon’s Nanoscale and Quantum Optics Lab. The team described their work in the latest issue of Nature Nanotechnology.

The silicon pillars have to be somewhat shorter than the wavelength of light they’re designed to manipulate. In the case of the metasurface described in the paper, the pillars are 715 nanometers tall, to handle infrared light with a wavelength of 915 nm. But they could easily be made shorter for visible light, Arbabi says. The pillars range in diameter from

5 Mobile App Development Trends to Look Out for In the Recent Future

Today, mobile device has emerged as a true friend in need, playing an important role in simplifying the routine tasks. We can’t deny the fact that the mobile technology is growing at a rapid pace and the mobile apps have become an integral part of the digital ecosystem. They are progressing to become omnipresent; so, staying up-to-date with the latest mobile app development trends has become an order rather than an option.
Below mentioned are a few mobile app development trends to look out for in the recent future:
  1. Connection to Back-End Systems: More and more users are demanding this feature quite often. And yes, it’s for the right reasons. Just imagine yourself sitting in front of a desktop computer looking for a product and you have to leave the house before you could finalize the order. You don’t have to worry if you have a mobile app as you can check out the offers on the go; but what if the app doesn’t have a shopping cart? This is where you feel that the app is useless. The app must be able to provide all the services as the desktop website; i.e. the apps must be connected to backend

4 Expert Tips For Being a Good Live Chat Agent

Being a live chat operator, your job isn’t easy. You have to be on your toes all the time and a lot is expected from you. You are not allowed to take extra breaks, and are ordered to stay focused. It is understandable for you to take the toll of the job, and sometimes it is frustrating to handle unbearable customers when you are loaded with a lot of work. But, if you channel your responsibilities wisely, and learn some rules by heart, your job as a live chat support operator might become easier.

Here are some useful expert advices that can help:

Just listen and don’t take anything personal

When the customer starts screaming, not many operators have the temperament to stay cool and quite a few retaliate and argue back. As said above, this act might be credited to the pressure of work, but most of the times it is so because operators take rude comments personally. You must always keep in mind that whatever the customer is saying has nothing to do with you, he does not even know who you are, and he is just angry at the company and venting out his frustration on you. So, the best

Measure Liquids to Know the Price Cost

Modern safety protocols demand the factory management to be aware of the amount of liquids that go in the waste pipelines. Since the waste liquids often fall in the city’s main waste pipeline, it often gets mixed up in places it shouldn’t have been. Most of the waste water is dumped into the river which then travels all through the country to fall into the ocean. Thus it not only makes the rivers toxic, but all the lands that take water from the river. One of the biggest challenges faced by the factories of today is controlling waste. Be it a waste of solid raw materials or liquids, anything that goes into the waste without being properly used increases production costs. While the competition grows globally, it has become necessary to bring down production costs to as minimum as possible.

When a factory does not control its costs incurred in production, ultimately the product when released to the market costs high and consumers do not purchase it. Thus, a huge loss is incurred and no business can function properly when it faces losses in huge amounts. Factory owners are now aware of the fact and we can
