Para facilitar la gestión de revistas, su publicación y difusión en línea la UNLP ha creado el proyecto denominado Portal de Revistas de la UNLP.
El portal sirve a revistas existentes que no cuentan con una versión digital, a…

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…

Las empleadas administrativas, representadas en la figura de la dactilógrafa, integraron el mundo del trabajo femenino en la ciudad de Buenos Aires, a lo largo de las décadas de 1920 y 1930. Por entonces, el sector administrativo de la economía…

An updated edition of the classic book on computer architecture by J. L. Hennessy and D. A. Patterson.
Authors show their high level standards for technological ideas, writing style, and teaching methodologies, all in one book. In fact, they maintain…

The book deals with the topic of Operating Systems from and intuitive perspective and then delves into more technical concepts, which makes it appropriate for a first introductory course on the matter.

This paper derives unbalanced versions of the tests statistics for first order serial correlation and random individual e®ects summarized in Sosa Escudero and Bera (2001), and updates their xttest1 routine. The derived tests statistics should be useful for applied researchers…
