Physical exercise is known to have beneficial effects on healthy individuals, but there are insufficient data concerning the effects of physical exercise in chronic end-stage kidney failure patients on haemodialysis. The aim of this study is to assess the effects…

The purpose of this pilot study was to develop and examine the psychometric properties of the Diabetic Care Teacher Support Questionnaire, a 31-item self-report instrument to assess diabetic children’s perceptions of the diabetes specific support received from their teachers at…

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…

For a mobile robot that interacts with humans such as a home assistant or a tour guide robot, activities such as locating objects, following specific people, and distinguishing among different people are fundamental, yet challenging robotic vision tasks. For complex…
