Learning How to Communicate in the Internet of Things: Finite Resources and Heterogeneity
(IEEE, 2016)For a seamless deployment of the Internet of Things (IoT), there is a need for self-organizing solutions to overcome key IoT challenges that include data processing, resource management, coexistence with existing wireless ... -
Modeling and Controller Design of a Bidirectional Resonant Converter Battery Charger
(IEEE, 2018)In this paper, a controller design methodology is proposed for a CLLLC-type bidirectional resonant converter. The soft switching of all devices in this topology and the very high operating frequency lead to increased overall ... -
Dynamic Resource Allocation for Optimized Latency and Reliability in Vehicular Networks
(IEEE, 2018)Supporting ultra-reliable and low-latency communications (URLLC) is crucial for vehicular traffic safety and other mission-critical applications. In this paper, a novel proximity and quality-ofservice-aware resource ... -
Mitigating the Impact of Renewable Variability With Demand-Side Resources Considering Communication and Cyber Security Limitations
(IEEE, 2019)With the rapid development of smart grid, the penetration of renewable energy resources is higher than ever and keeps growing. However, the output of renewable energy units, such as solar photovoltaics and wind turbines, ... -
Big Data Meet Cyber-Physical Systems: A Panoramic Survey
(IEEE, 2018)The world is witnessing an unprecedented growth of cyber-physical systems (CPS), which are foreseen to revolutionize our world via creating new services and applications in a variety of sectors, such as environmental ... -
Intermittently Nonlinear Impulsive Noise Mitigation and Doppler Shift Compensation in UWA-OFDM Systems
(IEEE, 2019)Impulsive noise (IN) and Doppler shift can significantly degrade the performance of orthogonal frequency-division multiplexing (OFDM)-based underwater acoustic (UWA) communication systems. In this paper, we propose a ... -
Direct observations of a surface eigenmode of the dayside magnetopause
(Nature Publishing Group, 2019-02-12)The abrupt boundary between a magnetosphere and the surrounding plasma, the magnetopause, has long been known to support surface waves. It was proposed that impulses acting on the boundary might lead to a trapping of these ... -
Differentiating between cancer and normal tissue samples using multi-hit combinations of genetic mutations
(Nature Publishing Group, 2019-01-30)Cancer is known to result from a combination of a small number of genetic defects. However, the specific combinations of mutations responsible for the vast majority of cancers have not been identified. Current computational ... -
