Pre - Stressed Concrete

Posted: 22 Feb 2011 10:43 AM PST

How come one of the interesting topic is not even opened !


The external loads cause tension in the bottom fibres which may lead to cracking, as shown. Reinforced concrete beams are usually cracked under the day-to-day service loads. On a cracked cross section, the applied moment is resisted by compression in the concrete above the crack and tension in the bonded reinforcing steel. Although the steel reinforcement provides the cracked concrete beam with flexural strength, it does not prevent cracking and does not prevent the loss of stiffness caused by cracking. Crack widths are approximately proportional to the strain, and hence stress, in the reinforcement. Steel stresses must therefore be limited to some appropriately low value in order to avoid excessively wide cracks. Similarly, large steel strain is the result of large curvature, which in turn is associated with large deflection. There is little benefit to be gained, therefore, by using higher strength steel or concrete, since in order to satisfy serviceability requirements, the increased strain capacity afforded by higher strength steel cannot be utilized.

Train Operators from All over the World Converge on St Pancras for WiFi on Trains Eve

Posted: 22 Feb 2011 08:46 AM PST

With WiFi on train services spreading rapidly across the world, this summer's 6th annual Train Communications Systems Conference, looks set to be the largest yet. The event, which is being held on the 8th and 9th of June at the newly re-opened Renaissance Hotel right above St Pancras International train station, has already attracted a cosmopolitan crowd of train companies from around the world to speak and attend (Traincomms 2011 Conference - BWCS).

"WiFi is a key weapon in the battle to get more passengers onto trains" says Graham Wilde, CEO of BWCS the wireless and transport consulting company hosting the conference. "The real value of WiFi services and, increasingly, of on-board entertainment services are not that the operator can squeeze a bit of loose change out of their passengers' pockets, but that they can help fill empty seats."

"For train companies, installing train to shore wireless connections gives them the chance to boost passenger levels, win plaudits from their customers, demonstrate a commitment to improving customer service and allows them to introduce cost-saving measures such as train engine performance monitoring." He added.

Train Communications Systems 2011 will be dominated by real case studies presented by train operators who have launched WiFi on-board services. It will offer a chance to hear how these go-ahead companies have overcome technical, marketing and operational issues to offer passenger WiFi and help win the battle to fill empty train seats and cut operating costs.

In addition several train operators are now beginning to develop new passenger entertainment and information services based on their high-speed wireless to train connections.

Among those presenting at Train Communications Systems 2011 will be: Amtrak, Russian Railways, Nuovo Trasporto Viaggiatori (Italian high-speed train operator), WestBahn (Austrian Train Company), Ferrocarrils de la Generalitat de Catalunya, Department for Transport, UK, China Railways, Bay Area Rapid Transit, SJ Trains, VR Trains Finland, and many more.

The conference is sponsored by Icomera, Nomad Digital, the GBS Group and EURail Magazine. 21Net is sponsoring a cocktail event at the end of the first day.

Full details are available on the website Traincomms 2011 Conference - BWCS or via e-mail from Ross.Parsons@BWCS.com

Unmanned Aerial Spy Vehicle That Imitates Hummingbird

Posted: 22 Feb 2011 04:00 AM PST

California based firm AeroVironment Inc. has successfully developed an unmanned flying vehicle which moves like a hummingbird. The robotic vehicle has a physical appearance which will make you confuse it with a live hummingbird. It flies, flaps its wings, rotates, flies sideways, climbs, descends and hovers around a place with so much precision and realistic [...]

history of micro controller

Posted: 22 Feb 2011 02:09 AM PST

hey friends,
after the history of micro processor now i came with the history of micro controller
as i learned in my class today i known that history of micro controller is great thing and i am posting it here

the first micro controller is hitachi hmcs 40
it is 4 bit micro controller it is a basic controller and mostly used in small applications

next coming to 8 bit micro controller here occur's two generations or types
these two are designed by intel
these two controllers are 8048 and 8051
these two are also used in small applications and 8051 is mostly used in small applications like speed control of D.C machines

next intel given the 16 bit micro controller
it is intel 80c196
this is mostly used in pwm applications

next coming to the 32 bit micro controller
this is also designed by intel it is intel 80960
it is mostly used in sophisticated technology like air craft landing
and it is in avionics
i believe all the CEans know about avionics

this all about the micro controllers history
hope all understood this topic and please post any additional matter is there if i had missed
