New system allows for high-accuracy, through-wall, 3-D motion tracking Imagine playing a video game like Call of Duty or Battlefield and having the ability to lead your virtual army unit while moving freely throughout your house. Gaming could become this realistic, thanks to new technology developed by Dina Katabi’s research group at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) that allows for highly accurate, 3-D motion tracking. The new system, dubbed “WiTrack”, uses radio signals to track a person through walls and obstructions, pinpointing her 3-D location to within 10 to 20 centimeters — about the width of an adult hand. The researchers will present their findings during the Usenix Symposium on Networked Systems Design and Implementation in April 2014. Earlier this year, Katabi and her graduate student Fadel Adib unveiled WiVi, a system that detects humans through walls and can track the direction of their movement using WiFi signals.
Wildlife Sound Recording Society | Getting started in Wildlife Sound Recording listen to a group of Long-Tailed Tits feeding recorded using equipment described. Richard Mudhar The newcomer to wildlife sound recording has a bewildering choice of a wide variety of sound recording equipment, designed for a whole range of applications from recording voice notes to recording orchestras. The obvious question he will ask is "what is the cheapest equipment to make wildlife sound recordings". This is what I have tried to make sense of here. Because most people starting out with wildlife sound recording are interested in recording birds, and generally want to record them from where they view them, this is written from that standpoint. Having the right gear is part of the story. I have pitched this at the amateur recordist in temperate latitudes, for whom cost is usually a greater issue than others, such a time and ruggedness. A basic sound recording kit is quite small the basics Let me start with the basics - what are the items you really need to record wildlife sounds?
The Twelve Senses - Fairy Dust Teaching Welcome to Saturday Senses! For the next twelve Saturdays I will feature one of the twelve senses. I am absolutely passionate about this model and what it provides in understanding how we process life. Actually, it is incredible to me that at the turn of the last century, Rudolf Steiner had realized we had more than the traditional five senses. He asserted we had twelve senses. What is so powerful about Steiner’s 12 senses model is the implications on teaching. Today, I want to give you a quick tour and overview. The Lower Senses – “Sensation” Senses – The Physical Senses The lower senses give us a certain consciousness of our body. Sense of Life – This sense allows us to experience our own constitution, whether we feel well or not (editic).Sense of Touch – This sense tells you something about the object you are touching and your sense of boundary (tactile).Sense of Movement – Gives us a sense of our joints and muscles when we move.

No. 25 ... "Pretty Boy," Young Galaxy | The 25 Best Songs of 2013 (The Entire Year) DrawCrowd Watch a robotic cube walk and balance under its own power Cubes aren't usually the go-to shape when creating an object that's meant to move around, but researchers in Switzerland have created one that can do just that — along with a handful of other surprising talents. Called the Cubli, it measures nearly 6 inches on each side and can walk around by continually flipping itself over. Perhaps more impressively, it can also balance on any of its sides or even just a single corner. As the research team from ETH Zurich's Institute for Dynamic Systems and Control demonstrates in a video, the cube can even remain balanced while a surface is raised up at an angle beneath it. Though it's a moving cube, the Cubli still relies on a series of spinning wheels to get going. A separate group of researchers at MIT demonstrated another use for blocks like this back in October: allowing a basic robot to reassemble itself.
To Find Your Next Great Business Idea, Narrow Your Focus When you’re just starting out in business, narrowing your target market can be difficult for fear you’ll be excluding part of your potential customer base. But if you can clearly define a market and its needs upfront, you can tailor your product or service offerings narrowly to meet that demand and quickly gain more wallet share than your competitors.

Simply walk or drive along any street and you’ll pass any number of businesses struggling to make ends meet because they aren’t selling what their market truly wants or needs. Category leaders tend to be highly focused, and many times, that focus can appear too narrow. 1.

Video of China's Historic Moon Landing Released It’s been a busy weekend for China’s moon mission Chang’e 3. After a successful landing on Saturday, the Beijing Aerospace Flight Control Center commanded the lander’s rover to roll onto the lunar surface early Sunday morning (Beijing Time). Now, a beautiful video has been released of the full landing sequence, shown here. At approximately 3 minutes into the video, the Chang’e 3 lander rotates to begin its vertical descent onto Sinus Iridum (the Bay of Rainbows), an ancient lava plain in the moon’s northern hemisphere. The descent onto lunar regolith had a very Apollo-landing feel as the lander’s thrusters blew moon dust away from the landing site at around the 6 minute mark.

My 7-Day Work Week Experiment Recently, I religiously tried to follow a new routine I created for myself: a 7-day work week routine. The idea was quite simple: I would work 7 days a week, rest 7 days a week, go to the gym 7 days a week, reflect 7 days a week. This was less about working lots, much more about feeling fulfilled every day, feeling stretched during the day but also rested. I aimed to work less each day, and replace two hours of work with a long break in the middle of the day. The biggest thing I wanted to do was to satisfy my craving of “why not?” and to challenge the status quo of working 5 days a week and then taking 2 days off. Some of the hypotheses I had about my new 7-day work week: The 7-day work week routine I’ve been an early riser for a couple of years now, and during this experiment I was rising at 4:30am. Results of the 7-day work week routine In the end, I have decided that I won’t continue with the 7-day work week routine. How the world works does affect you The wisdom of the day of rest
