Title          
FASTCAM MH4-10K : DigInfo 
   
 
Abstract    
DigInfo - http://movie.diginfo.tv Photron developed this high-speed camera system for use in vehicle safety tests. A single controller connects with up to four camera heads to enable the system to shoot high-speed, high-resolution imagery. By connecting multiple controllers to the system it is possible to monitor a greater number of angles using 8 to 12 camera heads. This camera system makes it possible to shoot high-speed (2,000 frames per second), high-resolution (512x512 pixels) images simultaneously from four different angles in order to evaluate motor vehicle safety during crash tests. The system enables engineers to obtain more detailed results than with previous camera systems. In motor vehicle crash tests it is necessary to shoot various locations within the vehicle compartment, and so it is necessary to position the cameras in confined spaces. To satisfy these requirements, Photron miniaturized the system camera heads. A single camera head weighs 100g and measures 35x35x34mm. Because the camera head is so small that it fits in the palm of even the tiniest of hands, it is possible to place numerous camera heads in previously hard to view spots such as the floor of the passenger seat, under the steering wheel, and so forth....

Title          
FASTCAM SA1 : DigInfo 
   
 
Abstract    
DigInfo - http://movie.diginfo.tv Photron, who produces high-speed video camera solutions, has just released its FASTCAM SA1. This high-speed camera can film 1,024x1,024 full-frame pixels at 5,400 frame/s. Segmented frame is available as well: 1,024x512 pixels at 10,000 frame/s; 128x128 pixels at 90,000 frame/s; and 128x32 pixels at the maximum speed of 150,000 frame/s. The camera comes with a 2-microsecond electronic shutter, an embedded CMOS sensor for color and monochrome shoots, and a collection of presets so as to not to initially overwhelm the user. It comes with 8GB of memory (easily expandable to 16GB) which can be subdivided into folders so you can organize your photos more effectively.

Title          
Text Compression and Searchability in Compres... 
   
 
Abstract    
In this paper, a new compression scheme for text is presented. The same is efficient in giving high compression ratios and enables super fast searching within the compressed text. Typical compression ratios of 70-80% and reducing the search time by 80-85% are the features of this paper. Till now, a trade-off between high ratios and searchability within compressed text has been seen. In this paper, we show that greater the compression, faster the search. This finds applicability in so many places where data as natural language text is present.

Title          
high speed camera: lighter 
   
 
Abstract    

A high speed camera is a device used for recording slow-motion playback films, or used for scientific study of transient phenomena.

http://en.wikipedia.org/wiki/High_speed_camera 

A normal motion picture is filmed and played back at 24 frames per second, while television uses 25 frames/s (PAL) to 29.97 frames/s (NTSC). High speed cameras can film up to 250,000 frames/s by running the film over a rotating prism or mirror instead of using a shutter, thus reducing the need for moving parts. Using this ...

Title          
dual cyclotron demo 
   
 
Abstract    
A cyclotron is a type of particle accelerator. Cyclotrons accelerate charged particles using a high-frequency, alternating voltage (potential difference). A perpendicular magnetic field causes the particles to spiral almost in a circle so that they re-encounter the accelerating voltage many times. Ernest Lawrence, of the University of California, Berkeley, is credited with the invention of the cyclotron in 1929. It is less known outside Hungary that Hungarian Sándor Gaál may have described the workings of a cyclotron at about the same time during the spring of 1929 as Lawrence;[citation needed] although almost all reputable international sources give credit to Lawrence for the invention and construction of the first cyclotron. He used it in experiments that required particles with energy of up to 1 MeV. In the cyclotron, a high-frequency alternating voltage applied across the "D" electrodes (also called "dees") alternately attracts and repels charged particles. The particles accelerate only when passing through the gap between the electrodes. The perpendicular magnetic field (passing vertically through the "D" electrodes) forces the particles to travel in a circular path. The particles move in a circle, because a curren...

Title          
High voltage disconnect switch 
   
 
Abstract    

An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Electric power may flow through several substations between generating plant and consumer, and may be changed in voltage in several steps.

A substation that has a step-up transformer increases the voltage while decreasing the current, while a step-down

Title          
Hovercraft Design - Maryland Part 1 of 3 
   
 
Abstract    

This is part 1 of 3 videos from the hovercraft design competition at the University of Maryland, Colllege Park. Part of ENES 100 program. The idea was to keep the hovercraft on the black guide line as it moved forward through the channel. There were two tricky turns the vehicles were needed to maneuver. A Lego Mindstorms NXT kit was programmed to control the vehicle.

A short extract from Wikipedia - (http://en.wikipedia.org/wiki/Hovercraft) A Hovercraft, or Air-Cushion Vehicle (ACV), is an amphibious vehicle or craft, designed to travel over any sufficiently smooth surface supported by a cushion of slowly moving, high-pressure air, ejected downwards against the surface close below it.Hovercraft have one or mo...
