Captain Basile is a robot inspired from the cockroach and built to participate at the SAE Walking Machine Challenge 2004, an undergraduate competition of walking robots. The robot weighs 35 kg and is 86 cm long, 58 cm wide and 38 cm tall. Initially validated by the use of dynamic simulations, this pneumatic actuated hexapod is characterised by specialized legs, passive visco-elastic elements an...

This paper proposes a RLC/MAC (Radio Link Control/Multiple Access Control) protocol architecture suitable for a wireless IP network. The RLC and MAC protocols have been designed to support packet transmission on an air interface. The MAC protocol uses a reservation technique to increase the multiplexing efficiency by minimising collisions. The RLC protocol is based on selective repeat technique...

Automatic data dissemination systems are becoming increasingly relevant in internet-based information systems. In such systems, users subscribe to the dissemination service by providing interest profiles. These profiles are then used to determine which information should be delivered to which users, whenever new information is entered into the system. A main shortcoming of existing disseminatio...

As documented by Darwin 150 years ago, emotion expressed in human faces readily draws our attention and promotes sympathetic emotional reactions. How do such reactions to the expression of emotion affect our goal-directed actions? Despite the substantial advance made in the neural mechanisms of both cognitive control and emotional processing, it is not yet known well how these two systems inter...

Background: Feeding behavior is regulated via a complex network which interacts through diverse signals from central and peripheral tissues. OBJECTIVES: The main purpose of the current study was to determine the role of central cannabinoidergic (CBergic) system on ghrelin-induced hypophagia in 3-h food deprived (FD3) neonatal chicken. METHODS: In experiment 1, chicks were ICV injected with cont...
