- 13901: Biometric Systems
- ... are close to biometrics but are not classified as such are behavioral systems such as voice, signature and keystroke systems. They test patterns of behavior not parts of the body. It seems that in the world of biometrics that the more effective the device, the less willing people will be to accept it. Retina pattern devices are the most reliable but most people hate the idea of a laser shooting into ... depending on what other information the operator wishes the user to enter. The system also keeps on record three of the individuals finger patterns incase one of the others is injured. Biometrics is still relatively new to most people and will remain expensive to purchase good equipment until it becomes more popular and the technology gets better. And as people become more aware of how the systems work they will become ...

- 13903: An Ergonomic Evaluation of the Kinesis Computer Keyboard
- ... manufacturer called Kinesis. This study looks not only on the effect of the keyboard on the users' body by mean of electromyographic activity but also on the learning rate of the users changing to this new style of keyboard. This is very useful since slow learning rate would lead to the decrease in effectiveness of work. Introduced in 1868 by Christopher Sholes, computer keyboard is still the primary data entry mode ... designs have not yet replaced the old one is because of the familiarity of the users to the old design. This means an amount of retraining time is required to familiarize the users to a new design of keyboard and thus the one requiring less time is likely to be the choice. This study main objectives are to measure and analyze initial learning rate and electromyographic activity, explained later, while using ... keyboard, the Kinesis Ergonomic Computer Keyboard (figure1.) These data are then used to compare to the standard computer keyboard, the old design, to see if it is worth the time and money spent on the new product. The electromyographic signals used to examine the muscle activities in this study are signals generated by muscles. These signals can sometimes be used to control artificial body limbs especially ones requiring sensitive or ...

The amount of deuterium found naturally in one liter of water is ... the lighter elements and have arrived at more accurate determinations of reaction rates. Also, the formulas developed by nuclear physicists for predicting the rate of fusion-energy generation have been adopted by astrophysicists to derive new information about the structure of the stellar interior and about the evolution of stars. The late 1960s witnessed a major advance in efforts to harness fusion reactions for practical energy production: the Soviets announced the ...
