Efficient simulation execution of cellular automata on GPU
(Elsevier, 2022)
Graphics Processing Units (GPUs) can be used as convenient hardware accelerators to speed up Cellular Automata (CA) simulations, which are employed in many scientific areas. However, an important set of CA have performance ...

Promoting accessibility by using metadata in the framework of a semantic-web driven CMS
(Dublin Core Metadata Initiative, 2005)
Web content accessibility for impaired people has been mainly addressed by the Web Content Accessibility Guidelines (WCAG) developed by the Web Accessibility Initiative (WAI) of the W3C Consortium. Those guidelines ...

A Two-Level Dynamic Chrono-Scheduling Algorithm
(IEEE Computer Society, 2009)
We propose a dynamic instruction scheduler that does not need any kind of wakeup logic, as all the instructions are “programmed” on issue stage to be executed in pre-calculated cycles. The scheduler is composed of two ...

Toward Parallel Computation of Dense Homotopy Skeletons for nD Digital Objects
(Springer, 2017)
An appropriate generalization of the classical notion of abstract cell complex, called primal-dual abstract cell complex (pACC for short) is the combinatorial notion used here for modeling and analyzing the topology of ...

A Cellular Automata Agent-Based Hybrid Simulation Tool to Analyze the Deployment of Electric Vehicle Charging Stations
(MDPI, 2021)
We present a hybrid model combining cellular automata (CA) and agent-based modeling (ABM) to analyze the deployment of electric vehicle charging stations through microscopic traffic simulations. This model is implemented ...

SIRIUS: Improving the maneuverability of powered wheelchairs
(IEEE Computer Society, 2002)
The indoor maneuverability of powered wheelchairs may be difficult or bothersome in several circumstances. In this paper, we describe an experimental powered wheelchair named SIRIUS, developed at the University of Seville, ...

Building Hierarchical Tree Representations Using Homological-Based Tools
(Springer, 2021)
A new algorithm for computing the α-tree hierarchical repre sentation of a grey-scale digital image is presented here. The technique is based on an efficient simplified version of the Homological Spanning For est (HSF) ...

An analytical model of inter-channel interference in Bluetooth-based systems
(IEEE Computer Society, 2002)
One of the main advantages of the Bluetooth standard is that it provides a way to support ad-hoc connectivity between a variable number of devices at low cost. However, in situations with many Bluetooth devices that coexist ...

Parallel Image Processing Using a Pure Topological Framework
(Universidad de Extremadura, 2016)
Image processing is a fundamental operation in many real time applications, where lots of parallelism can be extracted. Segmenting the image into different connected components is the most known operations, but there ...

A study of bus emulation. Application to M68000 based systems
(ScienceDirect, 1998-02)
With the important development of computer architectures, bus emulation becomes a very important tool. In this paper, methods for bus emulation are generally studied. We present several actual systems using this approach ...
