A Method for Dynamically Selecting the Best Frequency Hopping Technique in Industrial Wireless Sensor Network Applications
Fernández de Gorostiza, Erlantz; Berzosa Macho, Jorge; Mabe Alvarez, Jon; Cortiñas Rodríguez, Roberto (MDPI, 2018-02-23)
Industrial wireless applications often share the communication channel with other wireless technologies and communication protocols. This coexistence produces interferences and transmission errors which require appropriate ... -
A Survey of Performance Modeling and Simulation Techniques for Accelerator-Based Computing
López Novoa, Unai; ; (IEEE, 2014-02-25)
The high performance computing landscape is shifting from collections of homogeneous nodes towards heterogeneous systems, in which nodes consist of a combination of traditional out-of-order execution cores and accelerator ... -
A survey on Sign Language machine translation
