Along with the ever increasing popularity of cellular phones, improving recognition accuracy in cellular phone speech has become an issue of growing concern. However, the distortion caused by current low-bit rate speech CODEC is nonlinear, so compensating for distortion by applying only a conventional CMN which assumes distortion is a stationary linear transfer on the cepstrum domain is di cult...

In this study, 150 subjects observed a 25-minute video driving sequence containing 45 highway traffic situations to which they were expected to respond by manipulation of simulated vehicle controls. Each situation occurred under five conditions of distraction: placing a cellular phone call, carrying on a causal cellular phone conversation, carrying on an intense cellular phone conversation, tun...

Differences in cellular phones' complexity and their impact on children's performance are under study in this experiment. Twenty children (age 9-14 years) solved tasks on two phones that were simulated according to existing models on a PC with a touch screen, holding constant display size, fonts, and colors. Actions were logged and analyzed regarding execution time, detour steps, and specific e...

Breast cancer occurring in women under the age of 40 is uncommon in the absence of family history or genetic predisposition, and prompts the exploration of other possible exposures or environmental risks. We report a case series of four young women-ages from 21 to 39-with multifocal invasive breast cancer that raises the concern of a possible association with nonionizing radiation of electromag...

Background/purpose: Mobile phones, sometimes known as cell phones since they operate on a cellular network design, have grown significantly in size and technology over the years. Researchers at Bell Labs US started experimenting with idea of phone 1970s. The plan was to create hexagonal cells that would each base station cover entire nation. These stations use radio frequencies transmit receive...
