Wireless Sensor Network Topologies
2008-04-05 08:52:00
The development of network technologies has prompted sensor folks to consider alternatives that reduce costs and complexity and improve reliability. Early sensor networks used simple twisted shielded–pair (TSP) implementations for each sensor. Later, the industry adopted multidrop buses (e.g., Ethernet). Now we’re starting to see true web-based networks (e.g., the World Wide Web) implemented on the factory floor. Figure 1. In point-to-point network topologies, each sensor node requires a separate twisted shielded–pair wire connection. The cost is high, configuration management is difficult, and nearly all the information processing is done by the host.As wireless sensors become real commodities on the market, new options or new arguments for old options are causing professionals to consider network strategies once ruled out. Let’s look at the three classic network topologies (point-to-point, multidrop, and web), assess their strengths and weaknesses, and look at how the rule...

Components of robots
2008-03-31 07:09:00
The actuators are the 'muscles' of a robot; the parts which convert stored energy into movement. By far the most popular actuators are electric motors, but there are many others, some of which are powered by electricity, while others use chemicals, or compressed air.* Motors: By far the vast majority of robots use electric motors, of which there are several kinds. DC motors, which are familiar to many people, spin rapidly when an electric current is passed through them. They will spin backwards if the current is made to flow in the other direction.* Stepper Motors: As the name suggests, stepper motors do not spin freely like DC motors, they rotate in steps of a few degrees at a time, under the command of a controller. This makes them easier to control, as the controller knows exactly how far they have rotated, without having to use a sensor. Therefore they are used on many robots and CNC machining centres. * Piezo Motors: A recent alternative to DC motors are piezo motors, also ...

Smallville Season 7
2008-01-07 07:02:00
This season Clark will discover more about his home planet, who his parents were, what his future holds and why he was sent to Earth... Clark will face his biggest battles yet. Bizarro is intent on destroying him as only one of them can survive. Clark has also lost the love of his life to a horrific accident; his adoptive mother Martha has left for Washington; and the biggest trial for Clark comes in the form of his nineteen-year-old female cousin, Kara AKA Supergirl. When the dam broke, Kara's spaceship was released from the earth. She had been in suspended animation for years, having in fact left Krypton as a teenager with the intent to look after young Kal-El after he arrived on Earth. However, as she didn't age when inside the ship, she now finds herself younger than her cousin and he's now the one looking after her. Kara is fascinated with Earth's culture and has difficulty remembering to hide her powers from the world. Her youthful abandon puts her in several precarious si...

Introduction to Wireless Sensor Network(WSN)
2008-01-05 14:43:00
A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.[1][2] The development of wireless sensor networks was originally motivated by military applications such as battlefield surveillance. However, wireless sensor networks are now used in many civilian application areas, including environment and habitat monitoring, healthcare applications, home automation, and traffic control. In addition to one or more sensors, each node in a sensor network is typically equipped with a radio transceiver or other wireless communications device, a small microcontroller, and an energy source, usually a battery. The envisaged size of a single sensor node can vary from shoebox-sized nodes down to devices the size of grain of dust,[1] although functioning 'motes' of genuine micro...

Smileys
2007-12-31 10:11:00
Interestingly, the modern version of smileys which is now popular on the internet is what we most simply call today as emoticons (emotional icons). These are in a sense, smileys in graphics or graphical emotion symbols. These serve the same purpose as text based characters (smileys) and are just graphical representation of feelings. In other words, replacing them with some colorful images, or even animations (some are also able to produce sounds). One advantage of graphical emotion icons (graphical smileys) is that they are more easy to decipher, because of the graphic face that humans can read or interpret more readily from our daily interaction with people that we see or meet from our day to day activities. The untrained eye often finds these more easy to understand, when the sender express his/herself feelings, whether it was intended to indicate pleasure, approval, or humor in the form of an image. Interestingly it may not be a surprise to you to know that smileys (text based) c...

History of Puss
2007-12-18 15:44:00
Recommended to King Harold by Doris, the Ugly Stepsister and barmaid of the Poison Apple Inn as a famous ogre assassin, Puss is hired by the king to assassinate Shrek. However, unlike his fairy tale counterpart, he does not try to trick the ogre into changing into a mouse, but instead makes a direct, frontal assault on Shrek, which works up until the feline gags on a hairball, spitting it up. Shrek and Donkey think of what to do to with him as Donkey even proposes to give him the Bob Barker, but the swashbuckling cat begs for his life. Ultimately, they spare his life, and Puss proposes to the ogre he owes a life debt to him, in thanks. Although there is some tension/rivalry between Puss and Donkey (who seems nervous that Puss is taking his place as "annoying talking animal"), the three eventually become close friends and allies.Shrek appears to have accepted this debt, as Puss in Boots stays with him throughout the course of the film. Donkey had a particular rivalry with him, consid...
