Quislant-del-Barrio, Ricardo
; Gutiérrez-Carrasco, Eladio Damián; López-Zapata, Emilio; Plata-González, Óscar Guillermo (IEEE, 2017)
IBM and Intel now offer commercial systems with Transactional Memory (TM), a programming paradigm whose aim is to facilitate concurrent programming while maximizing parallelism. These TM systems are implemented in hardware ... -
Leveraging Irrevocability to Deal with Signature Saturation in Hardware Transactional Memory
Quislant-del-Barrio, Ricardo; Gutiérrez-Carrasco, Eladio Damián; López-Zapata, Emilio; Plata-González, Óscar Guillermo (Springer, 2017)
In hardware transactional memory, signatures have been proposed to keep track of memory locations accessed in a transaction to help conflict detection. Generally, signatures are implemented as Bloom filters that suffer ... -
Lightweight asynchronous scheduling in heterogeneous reconfigurable systems
Rodríguez-Moreno, Andrés; González-Navarro, María Ángeles; Nikov, Kris; Nunez-Yanez, José; Gran-Tejero, Rubén; Suárez Gracia, Darío; Asenjo-Plaza, Rafael[et al.] (Elsevier, 2022-03)
The trend for heterogeneous embedded systems is the integration of accelerators and general-purpose CPU cores on the same die. In these integrated architectures, like the Zynq UltraScale+ board (CPU+FPGA) that we target ... -
Measuring Improvement when Using HUB Formats to Implement Floating-Point Systems under Round-to-Nearest
Hormigo-Aguilar, Javier; Villalba-Moreno, Julio (IEEE, 2016)
This paper analyzes the benefits of using HUB formats to implement floating-point arithmetic under round-tonearest mode from a quantitative point of view. Using HUB formats to represent numbers allows the removal of the ... -

La Memoria Transaccional (TM) ofrece un modelo de ejecución concurrente optimista en arquitecturas multinúcleo, permitiendo a los programadores extraer paralelismo cuando la información de las dependencias de datos no está ... -
MgO-containing porous carbon spheres derived from magnesium lignosulfonate as sustainable basic catalysts
García-Rollán, Miguel; García-Mateos, Francisco José; Ruiz-Rosas, Ramiro Rafael; Rosas-Martínez, Juana María; Rodríguez-Mirasol, José; Cordero-Alcántara, Tomás[et al.] (Elsevier, 2022-11-26)
The presence of alkalis in lignosulfonate allows an easy preparation of sustainable MgO-containing carbon catalysts with surface basicity by carbonization of magnesium lignosulfonate and/or further partial gasification of ... -
miRNA as biomarker in lung cancer
Salcedo Lobera, Esperanza; Arroyo Varela, Macarena; Larrosa-Jiménez, Rafael; Bautista-Moreno, Rocío (Springer Nature, 2023-08-29)
Lung cancer has a high prevalence and mortality due to its late diagnosis and limited treatment, so it is essential to find biomarkers that allow a faster diagnosis and improve the survival of these patients. In this sense, ... -
Multimodal feature fusion for CNN-based gait recognition: an empirical comparison
Castro, Francisco M.; Marín-Jiménez, Manuel J.; Guil-Mata, Nicolás; Pérez de la Blanca, Nicolás (Springer London, 2020)
This paper focuses on identifying people based on their gait using a non-invasive approach. Traditional methods rely on gait signatures derived from binary energy maps, which introduce noise. Instead, the authors explore ... -
Multimodal features fusion for gait, gender and shoes recognition
Castro Payán, Francisco Manuel; Marín-Jiménez, Manuel J.; Guil-Mata, Nicolás (Springer, 2016)
This paper evaluates how fusing multimodal features (audio, RGB, and depth) can enhance the task of gait recognition, as well as gender and shoe recognition. While most previous research has focused on visual descriptors ... -
New formats for computing with real-numbers under round-to-nearest
Hormigo-Aguilar, Javier; Villalba-Moreno, Julio (2015-09-17)
In this paper, a new family of formats to deal with real number for applications requiring round to nearest is proposed. They are based on shifting the set of exactly represented numbers which are used in conventional ... -
New Results on Non-normalized Floating-point Formats
González-Navarro, Sonia; Hormigo-Aguilar, Javier (IEEE Computer Society, 2019)
Compulsory normalization of the represented numbers is a key requirement of the floating-point standard. This requirement contributes to fundamental characteristics of the standard, such as taking the most of the precision ... -
On an OptLearn implementation using collaborative filtering.
Fuster López, Alejandro; Guerrero-García, Pablo; Hendrix, Eligius María Theodorus; Martínez-Cruz, Jesús; Nowak, Ivo (2023)
The aim of the iMath project is to develop a recommender system where a student is recommended a next question or literature in a learning platform MathE. This paper describes the systems developed based on collaborative ... -
On conceptualisation and an overview of learning path recommender systems in e-learning.
Fuster López, Alejandro; Martínez-Cruz, Jesús; Guerrero-García, Pablo; Hendrix, Eligius María Theodorus; Košir, Andrej; Nowak, Ivo; Oneto, Luca; Sirmakessis, Spiros; Pacheco, Maria Fátima; Fernandes, Florbela Pires; Pereira, Ana Isabel[et al.] (2024-06-10)
The use of e-learning systems has a long tradition, where students can study online helped by a system. In this context, the use of recommender systems is relatively new. In our research project, we investigated various ... -
On Dealing with Minima at the Border of a Simplicial Feasible Area in Simplicial Branch and Bound.
