Predictive chiller operation: a data-driven loading and scheduling approach
(2019-01-01)
Article
Restricted access - publisher's policyThe proper sequencing and optimal loading of chillers is one of the major avenues for energy efficiency improvement in existing heating, ventilating and air conditioning installations. The main enabler for the success of ... -
Novel methods to measure the gravitational constant in space
(American Physical Society (APS), 2019-09-20)
Article
Open AccessWe present two novel methods, tested by LISA Pathfinder, to measure the gravitational constant G for the first time in space. Experiment 1 uses electrostatic suspension forces to measure a change in acceleration of a test ... -
A compact Thévenin model for a rectenna and its application to an RF harvester with MPPT
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-04-06)
Article
Open AccessThis paper proposes a compact Thévenin model for a rectenna. This model is then applied to design a high-efficiency radio frequency harvester with a maximum power point tracker (MPPT). The rectenna under study consists of ... -
Common mode electronic noise in differential circuits
(2019-07-01)
Article
Restricted access - publisher's policyDifferential circuits are assumed to reject common-mode noise yet no parameter is available to describethat rejection as the Common Mode Rejection Ratio (CMRR) applies only to deterministic signals, not torandom noise. We ... -
Incremental novelty detection and fault identification scheme applied to a kinematic chain under non-stationary operation
(2019-01-01)
Article
Restricted access - publisher's policyClassical methods for monitoring electromechanical systems lack two critical functions for effective industrial application: management of unexpected events and the incorporation of new patterns into the knowledge database. ... -

(Institute of Physics (IOP), 2019-09-20)
Article
Restricted access - publisher's policyThe zodiacal dust complex, a population of dust and small particles that pervades the solar system, provides important insight into the formation and dynamics of planets, comets, asteroids, and other bodies. We present a ... -
A photoplethysmography smartphone-based method for heart rate variability assessment: device model and breathing influences
(2020-03)
Article
Restricted access - publisher's policyA measurement method of heart rate and heart rate variability (HRV) based on smartphone has been developed and validated. The method is based on photoplethysmography (PPG) acquired with the smartphone camera (SPPG). SPPG ... -
Capacitance study of a polystyrene nanoparticle capacitor using impedance spectroscopy
(2019-07-19)
Article
Restricted access - publisher's policyIn this study, a metal-insulator-metal capacitor structure is fabricated using polystyrene nanoparticles. Impedance spectroscopy is used to evaluate the performance of this capacitor in which we found a significant magnitude ... -
