Chrono-Scheduling; a simplified dynamic scheduling algorithm for timing predictable processors
(World Scientific Connecting Great MInds, 2009)
We propose a simpler and latency-reduced instruction scheduler, called chronoscheduling algorithm, which avoids large and difficult instruction wake-up in order to reduce power consumption and latencies. The key idea of ...

Error adaptive tracking for mobile robots
(IEEE Computer Society, 2002)
In mobile robots it is usual that the desired trajectory is memorized or previously generated. When following a trajectory, there are several possibilities attending to the way in which the actual robot state can be related ...

A Path Following Control for Unicycle Robots
(John Wiley and Sons, 2001)
In this work we present a new path following control for unicycle robots that is applicable for almost all the possible desired paths and whose analysis is very straightforward. First we select the path following method ...

SIRIUS: Improving the maneuverability of powered wheelchairs
(IEEE Computer Society, 2002)
The indoor maneuverability of powered wheelchairs may be difficult or bothersome in several circumstances. In this paper, we describe an experimental powered wheelchair named SIRIUS, developed at the University of Seville, ...

An analytical model of inter-channel interference in Bluetooth-based systems
(IEEE Computer Society, 2002)
One of the main advantages of the Bluetooth standard is that it provides a way to support ad-hoc connectivity between a variable number of devices at low cost. However, in situations with many Bluetooth devices that coexist ...

Soft real-time communications over Bluetooth under interferences from ISM devices
(John Wiley and Sons, 2006)
Bluetooth is a suitable technology to support soft real-time applications like multimedia streams at the personal area network level. In this paper, we analytically evaluate the worst-case deadline failure probability ...

A parametric formulation of tracking methods: application to chained systems
(IEEE Computer Society, 2004)
When following a path, there are several possibilities attending to the way in which the actual robot state can be related with the whole path. In this work, we formulate different tracking methods on the base that a ...

Performance analysis of single-slave Bluetooth piconets under cochannel interference
(IEEE Computer Society, 2004)
We present an analytical model for single-slave Bluetooth piconets when the coexistence of multiple interfering devices produces collisions. Closed-form expressions for the channel throughput and the mean packet delay are ...
