8 janvier, minuit, banlieue de Téhéran, il neige. Quatre jeunes femmes répètent Les Bonnes de Jean Genet dans une maison. Ali, le fiancé de Fati, qui fait son service militaire dans la police, les rejoint. Il n’est pas censé être là, mais Fati a insisté. Bravant la loi qui interdit à un soldat de porter une arme dans un lieu privé, il promet à l’officier de service de revenir au poste avant l’aube. La neige l’en empêche. Abdi a lui aussi rejoint la répétition. Ils sont tous contraints de passer la nuit dans cette maison. Le lendemain quand Ali se réveille, il est seul et son arme a disparu. Mais la maison n’est pas le lieu de l’intrigue, ni l’arme l’enjeu véritable. La pièce tisse une suite de conversations téléphoniques au lendemain de cette nuit. En filigrane, les dialogues évoquent la situation actuelle de jeunes gens en Iran qui cherchent des moyens de se faire entendre. Figure de passeur dans le milieu théâtral iranien, Amir Reza Koohestani, auteur-metteur en scène accueilli en Europe depuis 2002, a récemment contribué, avec Oriza Hirata et Sylvain Maurice, au spectacle Des utopies? Entre symbolisme et réalisme, ne cessant d’échapper aux limites imposées par la censure, il tend au public un miroir de sa société.

The Special Project for Earthquake Disaster Mitigation in Urban Areas (2002-2006) conducted by the Earthquake Research Institute at the University of Tokyo. The project revealed the detailed geometry of the subducted Philippine Sea plate (PSP) beneath the Tokyo Metropolitan area and improved information needed for seismic hazards analyses of the largest urban centers. In 2007 the Special Project for Earthquake Disaster Mitigation in Tokyo Metropolitan Area started focusing at  the vertical proximity of the PSP down going lithospheric plate and the risks for the greater Tokyo urban region that has a population of 42 million and is the center of approximately 40 % of the nation's activities. A M 7 or greater (M 7+) earthquake in this region at present has high potential to produce devastating loss of life and property with even greater global economic repercussions. The Central Disaster Management Council of Japan estimated that a great earthquake in the region might cause 11,000 fatalities and 112 trillion yen (1 trillion US$) economic loss. The Earthquake Research Committee of Japan estimated a probability of 70 % in 30 years for a great earthquake in this region. 

With the introduction of the WEBENCH Online Design Environment in 1999, National Semiconductor made it possible for design engineers to create a reliable power supply circuit over the internet in minutes. The user specified the circuit performance and the WEBENCH Toolset delivered. Today, WEBENCH Designer creates and presents all of the possible power, lighting, or sensing circuits that meet a design requirement in seconds. This enables the user to make value based comparisons at a system and supply chain level before a design is committed. This expert analysis is not possible anywhere else.

aims at developing swarms of flying robots that can be deployed in disaster areas to rapidly create communication networks for rescuers. Flying robots are interesting for such applications because they are fast, can easily overcome difficult terrain, and benefit from line-of-sight communication.

People have been using pens to jot down their thoughts for thousands of years but now engineers at the University of Illinois have developed a silver-inked rollerball pen that allows users to jot down electrical circuits and interconnects on paper, wood and other surfaces. Looking just like a regular ballpoint pen, the pen's ink consists of a solution of real silver that dries to leave electrically conductive silver pathways. These pathways maintain their conductivity through multiple bends and folds of the paper, enabling users to personally fabricate low-cost, flexible and disposable electronic devices. While metallic inks have been used to manufacture electronic devices using inkjet printing technology, the silver pen offers users the freedom and flexibility to construct electronic devices on the fly, says Jennifer Lewis, the Hans Thurnauer professor of materials science and engineering at the University of Illinois who led the research team along with Jennifer Bernhard, a professor of electrical and computer engineering.

A couple things come to mind. For one, this is our last issue of "Angel" the ongoing hitting this week, but there's still one more issue of "Spike" which ties directly into Spike's reappearance in "Buffy." That hits next week, and then the week after is "Angel Yearbook" which is our final note with all these characters in the Whedonverse. I do a little two-page story that's essentially a goodbye and thank you to everybody. And what I'd leave you with here is just a huge appreciation for the fan base. These are a lot of people who haven't read comics regularly, and they are going to the shop every week and talking on message boards. That kind of passion and loyalty is really hard to get, and it's something you want to live up to. As we've done "Angel" for the last six years, the best I can hope for is that people are sad it's going away. I know fans will follow the characters to Dark Horse and their stories will continue, but the fact that there are a lot of people who have said they'll have a really hard time going on after us speaks a lot to their passion and loyalty for what we were doing. That's hugely appreciated on our part and made this really fun to do.

When all is said and done, there’ll only be a little Camelot. Starz has opted not to move forward with production on the series, which aired its first season finale earlier this month. “Due to significant production challenges, Starz has decided not to exercise the option for subsequent seasons of Camelot with our production partners GK-tv, Octagon Films and Take 5 Productions,” the cabler explains in a statement cited by The Hollywood Reporter.

Researchers at MIT's Object Based Media Group (OBMG), led by professor Michael Bove, have developed a 3D hologram using the Xbox Kinect and a laptop. Three GPUs on a graphic card are used to generate diffraction patterns that produce a Star-Wars-Style hologram at 15 frames per second. More information is available in a PopSci web article.

A new form of propulsion that could allow microrobots to explore human bodies has been discovered. The technique would be used to power robots and other devices such as microfluidic pumps from a distance. Finding a propulsion mechanism that works on the microscopic scale is one of the key challenges for developing microrobots. Another is to find a way to supply such a device with energy because there is so little room to carry on-board fuel or batteries. Now a team lead by Orlin Velev at North Carolina State University in Raleigh, US, has found that a simple electronic diode could overcome both these problems. Velev and Vesselin Paunov from the University of Hull, UK, floated a diode in a tank of salt water and zapped the set-up with an alternating electric field.

Tiny microbots swimming through liquid invariably conjures up images of Isaac Asimov's sci-fi classic Fantastic Voyage.But while microbots exist, and they can be made to swim, it's getting them to change direction that has been tricky so far - a bit of an issue if you're even planning on sticking them in a human body, for instance.Now a system used to propel swimming microbots without the need for on-board fuel has brought this idea one step closer. Researchers at North Carolina State University have coaxed their bots to perform U-turns on command.

Until now you can have big elaborate robots or very small microbots but it is very difficult to have both. A blog post from New Scientist (where this video is from) points out the research on microbots, very small machines that will move, navigate and perform simple tasks. The ability to remotely power a microbot, thus eliminating the need for onboard battery or fuel, is already proven and one of the methods is the application of an AC field to a liquid where the robot is located. This microbot is essentially a diode, a one-way electric conductor. The different electric charges at its ends force the neighboring ions to move thus creating a small thrust that propels the bot. The team of Rachita Sharma and Orlin Velev from North Carolina State University developed a method where a controlled application of an additional DC field changes the ion distribution around the microbot and this time the ion field creates a torque that rotates the microbot. The DC field is applied until the completion of a 180-degree turn. Then the microbot moves again, now in the opposite direction. It is only 1.3mm long and as claimed by other scientists like Vesselin Paunov from the University of Hull, UK this arrangement can be further scaled down where it can be useful for diagnostic and localized drug supply applications.

If you're a long time reader, you may remember our mention in 2008 of Emanuel Diamant's provocatively titled paper "I'm sorry to say, but your understanding of image processing fundamentals is absolutely wrong" (PDF). Diamant is back with a presentation created for the 3rd Israeli Conference on Robotics, with the equally provocative title: "It's Cognitive Robotics, Stupid" (PDF). In it he laments the lack of agreed upon definitions for words like intelligence, knowledge, and information that are crucial to the development of robotics.

Taylor Veltrop used a Kinect to read his arm movements which were then carried out by a robot. The robot was programmed using Willow Garage's open-source robot operating system (ROS). As Kit Eaton suggest, this quick experiment provides an illustration of the path towards robotic avatars.

Length-match your traces to within 100 mils. Or is it 10 mils? Or should you go down to 1 mil? Should you include the lengths of the vias? How about the lengths of resistors? Understanding the origin of length-matching requirements, coupled with some rudimentary signal integrity analysis, can help answer these questions.   Determining length requirements requires an understanding of flight time, electrical length vs. physical length, loading and signal quality. Those elements are vital in determining what the length really needs to be, as well as in determining the allowable trade-offs to meet system timing goals.

With all of the new competition in the consumer robotics field, it’s about time for iRobot to show that they’re still capable of innovating new and exciting things. AVA, their technology demonstrator, definitely fits into the new and exciting category. AVA is short for ‘Avatar,’ although iRobot was careful not to call it a telepresence robot so as not to restrict perceptions of what it’s capable of. AVA is capable of fully autonomous navigation, relying on a Kinect-style depth sensing camera, laser rangefinders, inertial movement sensors, ultrasonic sensors, and (as a last resort) bump sensors. We got a run-down a few days ago at CES, check it out:

When Pantelis Georgiou and his fellow biomedical engineers at Imperial College London decided to design an intelligent insulin pump for diabetes patients, they started at the source. "We asked ourselves, what does a pancreas do to control blood glucose?" Georgiou recalls. The answer is pretty well known: The organ relies primarily on two populations of cells—beta cells, to secrete insulin when blood glucose is high, and alpha cells, which release a hormone called glucagon when glucose levels are low. "We simulated them both in microchip form," Georgiou says. This biomimetic approach diverges from today's dominant method of delivering only insulin using a relatively simple control system.

German researchers have built an anthropomorphic robot hand that can endure collisions with hard objects and even strikes from a hammer without breaking into pieces. In designing the new hand system, researchers at the Institute of Robotics and Mechatronics, part of the German Aerospace Center (DLR), focused on robustness. They may have just built the toughest robot hand yet. The DLR hand has the shape and size of a human hand, with five articulated fingers powered by a web of 38 tendons, each connected to an individual motor on the forearm.
