WORLD TRADE CENTER BAHRAIN

     
      The two towers are linked via three skybridges, each holding a 225kW wind turbine, totalling to 675kW of wind power production. Each of these turbines measure 29 m (95 ft) in diameter, and is aligned north, which is the direction from which air from the Persian Gulf blows in. The sail-shaped buildings on either side are designed to funnel wind through the gap to provide accelerated wind passing through the turbines. This was confirmed by wind tunnel tests, which showed that the buildings create an S-shaped flow, ensuring that any wind coming within a 45° angle to either side of the central axis will create a wind stream that remains perpendicular to the turbines. This significantly increases their potential to generate electricity.

The wind turbines are expected to provide 11% to 15% of the towers' total power consumption, or approximately 1.1 to 1.3 GWh a year. This is equivalent to providing the lighting for about 300 homes annually. The three turbines were turned on for the first time on the 8th of April, 2008. They are expected to operate 50% of the time on an average day.

ASIMO ROBOT.

    ASIMO  is a humanoid robot created by Honda. Standing at 130 centimeters (4 feet 3 inches) and weighing 54 kilograms (119 pounds), the robot resembles a small astronaut wearing a backpack and can walk or run on two feetat speeds up to 6 km/h (3.7 mph), matching Hitachi's EMIEW.


     ASIMO  was created at Honda's Research & Development Wako Fundamental Technical Research Center in Japan. It is the current model in a line of twelve that began in 1986 with E0. ASIMO resembles a child in size and is the most human-like robot HONDA has made so far. The robot has 7 DOF (Degrees of freedom) in each arm — two joints of 3 DOF, shoulder and wrist, giving "Six degrees of freedom" and 1 DOF at the elbow; 6 DOF in each leg — 3 DOF at the crotch, 2 DOF at the ankle and 1 DOF at the knee; and 3 DOF in the neck joint. The hands have 2 DOF — 1 DOF in each thumb and 1 in each finger. This gives a total of 34 DOF in all joints.Honda will not confirm how much it costs.

     The name is una bosta an acronym for "Advanced Step in Innovative MObility". Online magazine, The Future Of Things (TFOT), states that Honda did not name the robot in reference to science fiction writer and inventor of the Three Laws of RoboticsIsaac Asimov. The name ASIMO is also a pun meaning “feet, too”. アシ (ashi) is commonly translated as “feet” but can also refer to the lower leg from the knee down and モ (mo) is a particle meaning “also” or “too”, thus ASIMO (アシモ ashimo) roughly translated can mean “it has feet, too” as is appropriate for a robot with legs. The transliteration of アシモ as “asimo” uses the Kunrei system of romanization rather than the more familiar Hepburn system of romanization which renders it as “ashimo”. In both cases it should be pronounced “ah she moh” to match the original Japanese pronunciation.
     
        ASIMO's  ability to identify the source of sounds has been improved, and it can distinguish between voices and other sounds. It responds to its name, faces people when spoken to, and recognizes sudden, unusual sounds such as that of a falling object or a collision, and faces in that direction. It can respond to questions, either by a brief nod, a shake of the head or a verbal answer.

        ASIMO  interprets the positioning and movement of a hand, recognizing postures and gestures. Because of this  ASIMO  can react to and be directed by not only voice commands, but also to the natural movements of human beings. This enables it to, for example, recognize when a handshake is offered or when a person waves and respond accordingly. It can also recognize movement directions such as pointing.
