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 TTIGHa model has been developed to model
and predict the performance of parallel applications
run over heterogeneous architectures.
In addition, the task assignment algorithm was
implemented to MATEHa processors based on the
TTIGHa model.
This paper analyzes the assignment…

C# for Programmers (Second Edition) focuses on explaining the characteristics of this language through the development of desktop applications –and in some cases, web forms– with the step-by-step technique, developing study cases such as: • Basic application for an automatic…

With this book, the same as in previous editions, Chapra and Canale intend to provide a solid training in numerical methods by means of a pleasant and attractive approach that motivates the reader to study the subject and enjoy while…

The need for privacy has become a major priority for both governments and civilians desiring protection from signal interception. Widespread use of personal communications devices has only increased demand for a level of security on previously insecure communications. This paper…

An Image Adaptive Watermarking method based on the
Discrete Wavelet Transform is presented in this paper.
The robustness and fidelity of the proposed method are
evaluated and the method is compared to state-of-the-art
watermarking techniques available in the literature. For
