This paper introduces the conceptual design of a new information technology integrating wireless telephony and Internet services to assist in locating lost or displaced people in a moment of crisis. This public safety service is based on a novel text…

Scientific collaboration are becoming interdisciplinary, and scientists are working in informal collaboration to solve complex problems that require multiple types of large resources. An option is a computational grid. A computational grid is a distributed infrastructure that appears to the…

One of the main challenges of modern processor
designs is the implementation of scalable and
efficient mechanisms to detect memory access
order violations as a result of out-of-order
execution. Conventional structures performing this
task are complex, inefficient and power-hungry.
This…

MINIX4RT is an extension of the well-known MINIX
Operating System that adds Hard Real-Time services in a new
microkernel but keeping backward compatibility with standard
MINIX versions.
Semaphores are the primitive synchronization and mutual
exclusion mechanism in many operating systems,…

Asymmetric or heterogeneous multi-core (AMC) architectures have definite performance, performance per watt and fault tolerance advantages for a wide range of workloads. We propose a 16 core AMC architecture mixing simple and complex cores, and single and multiple thread cores…

Segmentation is often a critical step in image
analysis. Microscope image components show great
variability of shapes, sizes, intensities and textures.
An inaccurate segmentation conditions the ulterior
quantification and parameter measurement.
The Watershed Transform is able to distinguish
extremely complex…

In this paper, we present a new model of an artificial
immune system (AIS), based on the process
that suffers the T-Cell, it is called T-Cell
Model. It is used for solving constrained (numerical)
optimization problems. The model operates
on…

Based on known data sets and maximum entropy distribution data of fern and lycopod species registered in the Yucatan Peninsula, track and parsimony analyses were undertaken to evaluate the contribution of these groups to the establishment of biogeographical relationships of…

The Workshop of Physical Agents intends to be a forum for information and experience exchange in different areas regarding the concept of agent on physical environments, especially applied to the control and coordination of autonomous systems: robots, mobile robots, industrial…

This paper presents a brief summary of the post-proceedings of the special session on practical applications held in the framework of IWANN 2009. The special session was supported by the THOMAS (TIN2006-14630-C03-03) project and aims at presenting the results obtained…
