A simulated annealing algorithm for zoning in planning using parallel computing
(Pergamon Press, 2016)
[Abstract] There is an increasing demand for tools that support land use planning processes, particularly the design of zoning maps, which is one of the most complex tasks in the field. In this task, different land use ...
Using Artificial Vision Techniques for Individual Player Tracking in Sport Events
(M D P I AG, 2019-07-31)
[Abstract] We introduce a hybrid approach that can track an individual football player in a video sequence. This solution achieves a good balance between speed and accuracy, combining traditional object tracking techniques ...
Rendering of Bézier Surfaces on Handheld Devices
(Vaclav Skala - Union Agency, 2013)
[Abstract] Bézier surfaces have been widely employed in the designing of complex scenes with high-quality results. Nevertheless, parametric surfaces cannot be directly rendered in the current GPUs of modern handheld devices. ...
High-Speed FPGA Architecture for CABAC Decoding Acceleration in H.264/AVC Standard
(Springer New York LLC, 2013-08)
[Abstract] Video encoding and decoding are computing intensive applications that require high performance processors or dedicated hardware. Video decoding offers a high parallel processing potential that may be exploited. ...
Efficient Culling Techniques for Interactive Deformable NURBS Surfaces on GPU
(SciTePress, 2016-02)
[Abstrtact] InfoValue: NURBS (Non-uniform rational B-splines) surfaces are the standard freeform representation in Computer-Aided Design (CAD) applications. Rendering NURBS surfaces accurately while they are interactively ...
Communication avoiding and overlapping for numerical linear algebra
(IEEE Computer Society, 2013-02-25)
[Abstract] To efficiently scale dense linear algebra problems to future exascale systems, communication cost must be avoided or overlapped. Communication-avoiding 2.5D algorithms improve scalability by reducing inter-processor ...
Texture Mapping on NURBS Surface
(M D P I AG, 2018-09-17)
[Abstract] Texture mapping allows high resolution details over 3D surfaces. Nevertheless, texture mapping has a number of unresolved problems such as distortion, boundary between textures or filtering. On the other hand, ...
Implementing Parallel Differential Evolution on Spark
(Springer, 2016-04-02)
[Abstract] Metaheuristics are gaining increased attention as an efficient way of solving hard global optimization problems. Differential Evolution (DE) is one of the most popular algorithms in that class. However, its ...
Optimization of Real-World MapReduce Applications With Flame-MR: Practical Use Cases
(Institute of Electrical and Electronics Engineers, 2018-11-12)
[Abstract] Apache Hadoop is a widely used MapReduce framework for storing and processing large amounts of data. However, it presents some performance issues that hinder its utilization in many practical use cases. Although ...
Prediction of missing sequences and branch lengths in phylogenomic data
(Oxford University Press, 2016-01-05)
[Abstract] Motivation: The presence of missing data in large-scale phylogenomic datasets has negative effects on the phylogenetic inference process. One effect that is caused by alignments with missing per-gene or per-partition ...
