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…

The electrochemical reduction of perchloroethylene (PCE) in water has been analyzed through voltammetric studies with a
rotating disc electrode and controlled potential bulk electrolysis. The influence of the mass transport conditions and initial concentration on lead, copper and carbon electrodes…

Virtual and remote laboratories have improved
learning and training in the academic community. They allow students to acquire methods, skills and experience related to real equipment in an intuitive and cost-effective way. The purpose of this paper is to present…

The Millennium Development Goals (MDG) progress targets have not been met. Nevertheless, the United Nations (UN) has not yet undertaken in-depth review in order to discover the reasons behind this lack of progress in achieving the MDG. From a political…

Nanostructured cobalt oxide (Co3O4) electrodes were prepared by two different methods. The first one involved the synthesis of Co3O4 nanoparticles through a nanocasting route using commercial silica gel as a sacrificial template, and in the second one, the Co3O4 electrodes…
