Position-dependent exact-exchange energy for slabs and semi-infinite jellium
(American Physical Society, 2009-12)
The position-dependent exact-exchange energy per particle epsilon(x)(z) (defined as the interaction between a given electron at z and its exact-exchange hole) at metal surfaces is investigated, by using either jellium slabs ...
Exchange-Correlation Hole of a Generalized Gradient Approximation for Solids and Surfaces
(American Physical Society, 2009-02)
We propose a generalized gradient approximation (GGA) for the angle- and system-averaged exchange-correlation hole of a many-electron system. This hole, which satisfies known exact constraints, recovers the Perdew-Burke-Ernzerhof ...
An on-line VAD based on Multi-Normalisation Scoring (MNS) of observation likelihoods
(Elsevier Ltd., 2018-05-31)
Voice activity detection (VAD) is an essential task in expert systems that rely on oral interfaces. The VAD module detects the presence of human speech and separates speech segments from silences and non-speech noises. The ...
When the sun never sets: daily changes in pigment composition in three subarctic woody plants during the summer solstice
(Springer, 2018-02-02)
Composition and content of photosynthetic pigments is finely tuned by plants according to a subtle equilibrium between the absorbed and used energy by the photosynthetic apparatus. Subarctic and Arctic plants are subjected ...
Elucidation of the Chemical Role of the Pyroclastic Materials on the State of Conservation of Mural Paintings from Pompeii
(Wiley, 2020-10-16)
Pyroclastic strata have always been thought to protect the archaeological remains of the Vesuvian area (Italy), hence allowing their conservation throughout the centuries. In this work, we demonstrate that they constitute ...
High performance platform to detect faults in the Smart Grid by Artificial Intelligence inference
(IEEE, 2023-04-27)
Inferring faults throughout the power grid involves fast calculation, large scale of data, and low latency. Our heterogeneous architecture in the edge offers such high computing performance and throughput using an Artificial ...
AXI Lite redundant on-chip bus interconnect for high reliability systems
(IEEE, 2023-04-27)
Nowadays, system-on-chips have become critical since they support more and more safe applications due to their flexibility. However, they are susceptible to single-event upsets because the memory cell size has significantly ...
Parametric Study of the Device Angle Dependency of a Single Vortex Generator on a Flat Plate
(2014-01-23)
[EN] A detailed study of the device angle dependency of a single vortex generator (VG) is presented in this paper. A single Vortex Generator on a test section wall case, with four different positions of the device angle ...
Multirating decision model validation: the relevance of the quality of the securitization issues
(Incisive Media, 2013)
Rating enables the information asymmetry existing in the issuer-investor relationship to be reduced, particularly for issues with a high degree of complexity, as is the case of securitizations. However, there may be a ...
An architecture for dynamic QoS management at Layer 2 for DOCSIS access networks using OpenFlow
(Elsevier, 2016-01-15)
Over the last few years, Software-Defined Networking (SDN) has emerged as one of the most disruptive and profitable novelties in networking. SDN was originally conceived to improve performance and reduce costs in Ethernet-based ...
