Reactive Power Limits in Distributed Generators from Generic Capability Curves
(2014-07-27)This paper presents a generic trapezoid-type capability curve for any distributed generation technology. This curve is used to estimate the machine reactive power limits in terms of the actual active power and terminal ... -
Reconstructing fundamental frequency from noisy speech using initialized autoencoders
(2020-10)In this paper, we present a new approach for fundamental frequency (f0) detection in noisy speech, based on Long Short-term Memory Neural Networks (LSTM). f0 is one of the most important parameters of human speech. Its ... -
Resolution improvements on poly(methyl methacrylate) as electron-beam resist
(San José, Costa Rica, 2012-10-23)The present thesis expands the topic of lithographic resolution improvement of poly(methyl methacrylate) (PMMA) as a positive tone electron-beam resist. The investigation used electron-beam lithography (EBL) to define ... -
Review of residential PV-storage architectures
(2016)This paper focuses on the most common PV-storage architectures that are designed for residential applications and that incorporate storage devices like batteries, hydrogen systems, supercapacitors, and flywheels. The main ... -
Robotic architecture design to map an action language to a low level motion commands for skillful manipulation
(2019)This paper gives an overview of a robotic architecture meant for skillful manipulation. This design is meant to close the gap between the high level layer (reasoning and planing layer) and the object model system (physical ... -

Robust energy system planning for decarbonization under technological uncertainty: From transport electrification to power system investments
(2022-08-25)This work develops energy system modeling tools that identify features of a robust energy policy: a policy that performs well relative to alternatives. The tools are based on the Open Souce Modeling System (OSeMOSYS), are ... -
Robust PI/PID controllers for load disturbance based on direct synthesis
(2018-10)It is recognized that disturbance rejection is much more important than set-point tracking for many process control applications, leading set-point tracking to a secondary level of interest. In this paper a proposal for ... -
Robustness of LSTM neural networks for the enhancement of spectral parameters in noisy speech signals
(2019)In this paper, we carry out a comparative performance analysis of Long Short-term Memory (LSTM) Neural Networks for the task of noise reduction. Recent work in this area has shown the advantages of this kind of network for ... -
Robustness/performance tradeoff for anisochronic plants with two degrees of freedom PID controllers
(2015)In this paper, the anisochronic model (which is able to represent both over-damped and under-damped process with the same topology) is used for the tuning of PI and PID controllers. The relationship between robustness and ... -
Selecting a suitable battery technology for the photovoltaic battery integrated module
(2019-10-31)The use of batteries is indispensable in stand-alone photovoltaic (PV) systems, and the physical integration of a battery pack and a PV panel in one device enables this concept while easing the installation and system ... -
