Due to the explosive popularity of peer-topeer (P2P) file-sharing services, there have been remarkable research efforts on the P2P live streaming services. P2P systems are cost-effective and can be easily deployed only by leveraging the participating peer’s resources (i.e., upload link bandwidth) to distribute contents. In this paper, we propose Climber, an incentive-based resilient P2P system ...

A toy optimisation problem is introduced which consists of a ÿtness gradient broken up by a series of hurdles. The performance of a hill-climber and a stochastic hill-climber are computed. These are compared with the empirically observed performance of a genetic algorithm (GA) with and without. The hill-climber with a suuciently large neighbourhood outperforms the stochastic hill-climber, but i...

Determining the best combinations of variety choice and planting date may be crucial for farmers in view of optimising bean yields. A study was conducted to assess the agronomic performance of selected dry bean (Phaseolus vulgaris L.) lines when planted sequentially under rain fed conditions in the Western Highlands of Cameroon (WHC). Forty two introduced lines and three local checks were used,...

This study examines the osteological changes in the hands and fingers of rock climbers that result from intense, long-term mechanical stress placed on these bones. Specifically, it examines whether rock climbing leads to metacarpal and phalange modelling in the form of increased cortical thickness as well as joint changes associated with osteoarthritis. This study also attempts to identify spec...

This article describes a novel mobile wall-climbing robot named City-Climber that has the capabilities to move on the ground, climb walls, walk on ceilings, and transit between different surfaces. Unlike the traditional climbing robots using magnetic devices and vacuum suction techniques, and the robots inspired by the gecko foot, the City-Climber robot is based on aerodynamic attraction which ...
