Measuring Improvement when Using HUB Formats to Implement Floating-Point Systems under Round-to-Nearest
(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 ... -
Mejorando el rendimiento de la memoria transaccional para aplicaciones irregulares
(2018-11-15)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 ... -
Memoria Transaccional Hardware en Memoria Local de GPU
(2015-09-25)Los aceleradores gráficos (GPUs) se han convertido en procesadores de prop ́osito general muy populares para el cómputo de aplicaciones que presen- tan un gran paralelismo de datos. Su modelo de ejecución SIMT (Single ... -
Memoria Transaccional Software en Procesadores CPU+GPU Heterogéneos
(2018-09-19)En los procesadores multi-núcleo, la memoria transaccional (TM) ha aparecido como una alternativa prometedora a las técnicas basadas en cerrojos para garantizar exclusión mutua y está siendo incluida como parte de procesadores ... -
MgO-containing porous carbon spheres derived from magnesium lignosulfonate as sustainable basic catalysts
(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
(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, ... -
Modelling vessel fleet composition for maintenance operations at offshore wind farms
(2018-12-20)Chartering a vessel fleet to support maintenance operations at offshore wind farms (OWF's) constitutes one of the major costs of maintaining this type of installations. Literature describes deterministic optimization models ... -
Multimodal feature fusion for CNN-based gait recognition: an empirical comparison
(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
(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 ... -
Multimodal Human Pose Feature Fusion for Gait Recognition.
(2023)Gait recognition allows identifying people at a distance based on the way they walk (i.e. gait) in a non-invasive approach. Most of the approaches published in the last decades are dominated by the use of silhouettes or ... -
Multiset Signatures for Transactional Memory
(ACM, 2011)Transactional Memory (TM) systems must record the memory locations read and written (read and write sets) by concurrent transactions in order to detect conflicts. Some TM implementations use signatures for this purpose, ... -
NATSA: A Near-Data Processing Accelerator for Time Series Analysis.
(IEEE, 2020)El análisis de series temporales es una técnica clave para extraer y predecir sucesos en ámbitos tan diversos como la epidemiología, la genómica, la neurociencia, las ciencias medioambientales o la economía, entre otros. ... -
New formats for computing with real-numbers under round-to-nearest
(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
(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 ... -
Normalizing or not normalizing? An open question for floating-point arithmetic in embedded systems
(IEEE, 2017-07-24)Emerging embedded applications lack of a specific standard when they require floating-point arithmetic. In this situation they use the IEEE-754 standard or ad hoc variations of it. However, this standard was not designed ... -
Novel parallel approaches to efficiently solve spatial problems on heterogeneous CPU-GPU systems
(UMA Editorial, 2022)In recent years, approaches that seek to extract valuable information from large datasets have become particularly relevant in today's society. In this category, we can highlight those problems that comprise data analysis ... -
On an OptLearn implementation using collaborative filtering.
(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 computational procedures for Value Iteration in inventory control
(2019-09-11)Dynamic programming (DP) is often seen in inventory control to lead to optimal ordering policies. When considering stationary demand, Value Iteration (VI) may be used to derive the best policy. In this paper, our focus is ... -
