Device-to-Device communications underlying the cellular infrastructure is a technology that has recently been proposed as a promising solution to enhance cellular network capabilities. However, interference is the major challenge since the same resources are shared by both systems. Therefore, interference management techniques are required to keep the interference under control. In this work, in order to mitigate interference, we consider centralized and distributed power control algorithms in a one-cell random network model. Differently from previous works, we are assuming that the channel state information may be imperfect and include estimation errors. We evaluate how this uncertainty impacts performances. In the centralized approach, we derive the optimal powers that maximize the coverage probability and the rate of the cellular user while scheduling as many D2D links as possible. These powers are computed at the base station (BS) and then delivered to the users, and hence the nameCitation

Instant messaging-based dialog system for device control in the internet of things Sistema de diálogo basado en mensajería instantánea para el control de dispositivos en el internet de las cosasNoguera-Arnaldos, José Ángel; Paredes-Valverde, Mario Andrés; Valencia-García, Rafael; Rodriguez-Garcia, Miguel Angel (Procesamiento de Lenguaje Natural, Sociedad Espanola para el Procesamiento del Lenguaje Naturalsidsepln@si.ehu.es, 2015-01-01) [Article]The im4Things project aims to develop a communication interface to devices on the Internet of the Things (IoT) through intelligent dialogue based on written natural language over instant messaging services. This communication can be established in different ways such as order sending, status querying and even the devices themselves are responsible for alert users when a change has been produced in the devices sensors. This project is being developed by Proasistech company in cooperation with the TECNOMOD research group of the University of Murcia and it has been funded by equity capital of Proasistech company and by an R&D&i technology consulting contract with the aforementioned University of Murcia research group.

Phase control of 2D binary hydroxides nanosheets via controlling-release strategy for enhanced oxygen evolution reaction and supercapacitor performancesWei, Min; Li, Jing; Chu, Wei; Wang, Ning (Journal of Energy Chemistry, Elsevier BV, 2019-01-09) [Article]An OH-slow-release strategy was established to controllably tune the (α- and β-) phase of nickel cobalt binary hydroxide in the presence of ammonium chloride. Ammonium chloride is added to the ionic solution to regulate the pH of the solution and slow down the release of OH, effectively regulating the phase, nanostructure, interlayer spacing, surface area, thickness, and the performance of binary Ni–Co hydroxide. The ion-slow-release mechanism is conducive to the formation of α-phase with larger interlayer spacing and thinner flakes rather than β-phase. Attributed to the enlarged interlayer spacing, thinner nanosheets, and more exposed active sites, the resultant α-phase hydroxides (NCNS-5.2), displayed much lower over potential of 285 mV with respect to the dense-stacked β-phase hydroxides (362 mV) for OER at 10 mA/cm. It also exhibited high specific capacitance of 1474.2 F/g, when tested at 0.5 A/g within a voltage range of 0–0.45 V vs. Hg/HgO. This composite was also stable for water oxidation reaction and supercapacitor. The proof-of-concept of using controlled-release agent may provide suggestive insights for the material innovation and a variety of applications.

The compute and control for adaptive optics (CACAO) real-time control software packageGuyon, Olivier; Sevin, Arnaud; Ltaief, Hatem; Skaf, Nour; Martinache, Frantz; Gratadour, Damien; Cetre, Sylvain; Males, Jared R.; Lozi, Julien; Clergeon, Christophe S.; Bernard, Julien; Norris, Barnaby; Wong, Alison; Sukkari, Dalal E. (Adaptive Optics Systems VI, SPIE-Intl Soc Optical Eng, 2018-07-11) [Conference Paper]The compute and control for adaptive optics (cacao) package is an open-source modular software environment for real-time control of modern adaptive optics system. By leveraging many-core CPU and GPU hardware, it can scale up to meet the demanding computing requirements of current and future high frame rate, high actuator count adaptive optics (AO) systems. cacao's modular design enables both simple/barebone operation, and complex full-featured AO control systems. cacao's design is centered on data streams that hold real-time data in shared memory along with a synchronization mechanism for computing processes. Users and programmers can add additional features by coding modules that interact with cacao's data stream format. We describe cacao's architecture and its design approach. We show that accurate timing knowledge is key to many of cacao's advanced operation modes. We discuss current and future development priorities, including support for machine learning to provide real-time optimization of complex AO systems.
