From user perspective, given a keyword or a phrase, getting the relevant results in the order of milliseconds is an astounding feat. On submission of user request it is assumed that search engines "search the web for the required, relevant information" and respond to the user by giving a summary sheet, ordered on some criterion (C). Google certainly has taken the web community by awe and inspir...

This paper presents an effectively unbiased nonlinear estimation scheme which identifies tire longitudinal stiffness and effective radius using GPS and ABS wheelspeed sensors. This estimation strategy is then used to experimentally identify the longitudinal stiffness and effective radius of a summer tire and a winter tire under several different test conditions. The data clearly shows that ther...

This review discusses key technologies of intelligent tires focusing on sensors and wireless data transmission. Intelligent automobile tires, which monitor their pressure, deformation, wheel loading, friction, or tread wear, are expected to improve the reliability of tires and tire control systems. However, in installing sensors in a tire, many problems have to be considered, such as compatibil...

Peak to average Power Ratio (PAPR) is the major drawback of orthogonal Frequency Division Multiplexing (OFDM) systems. Since OFDM is the indispensable technology for 4G wireless schemes, great attention is given to PAPR reduction. Some of the techniques classified under signal distortion and signal scrambling already existing to meet the needs, but their effectiveness is still a question for re...

NOBODY knows when, where or how speech originated, and I am stepping in where wise scholars in linguistics and psychology fear to tread. My colleagues in psychology will, I beg, permit this divagation into speculation by one who has labored long in the less exciting fields of experiment and statistics. I ask and expect no mercy from experts in linguistic science, but only that they build a bett...

Nonlinear hunting speeds of railway vehicles running on a tangent track are analytically obtained using Hopf bifurcation theory in this paper. The railway vehicle model consists of nonlinear primary yaw dampers, nonlinear flange contact stiffness as well as the clearance between the wheel flange and rail tread. Linear and nonlinear critical speeds are obtained using Bogoliubov method. A compreh...
