This work presents operation and the results obtained in an information-centric multiaccess content distribution prototype using both real laboratory environment tests and simulation experiments with OMNeT++. We present the basic objectives and mechanisms of our solution and evaluate it against a standard BitTorrent. The results show that our prototype based on an information-centric approach c...

In this paper the kinematic analysis and design are presented for a 1DOF (Degree-of-Freedom) pantograph-leg for walking machines. A preliminary prototype of a low-cost leg, which is capable of a straight walking with only one actuator, has been designed and built at LARM: Laboratory of Robotics and Mechatronics in Cassino. Simulation and experimental validation have been carried out to verify t...

A prototype rf power source based on the Relativistic Klystron Two-Beam Accelerator (RK-TBA) concept is being constructed at the Lawrence Berkeley National Laboratory to study physics, engineering, and costing issues. The prototype, called the RTA, is described and compared to a full scale design appropriate for driving the Next Linear Collider (NLC). Specific details of the induction core test...

This paper describes the evolution of Assistant Personal Robot (APR) project developed at Robotics Laboratory University Lleida, Spain. first APR-01 prototype developed, basic hardware improvement, specific anthropomorphic improvements, and preference surveys conducted with engineering students from same university in order to maximize perceived affinity final APR-02 mobile robot prototype. The...

The fundamental problem of pulse-width modulation (PWM) based open-loop digital Class-D audio power amplifiers is the inherent nonlinearity of the PWM process, which necessitates the application of a precompensating linearization algorithm. Severe technical difficulties arising from the stringent speed requirements of both electronic circuitry, and digital signal processing devices make the imp...
