Towards retrieving force feedback in robotic-assisted surgery: a supervised neuro-recurrent-vision approach
(Institute of Electrical and Electronics Engineers (IEEE), 2017-07-01)
Article
Open AccessRobotic-assisted minimally invasive surgeries have gained a lot of popularity over conventional procedures as they offer many benefits to both surgeons and patients. Nonetheless, they still suffer from some limitations ... -
MMC-based solid-state transformer model including semiconductor losses
(2017-09-06)
Article
Restricted access - publisher's policyThis paper presents the model of a solid-state transformer (SST) for distribution system studies with some advanced features. The model is based on a previous work in which a bidirectional SST with a MV-side modular ... -
A virtual power plant model for time-driven power flow calculations
(2017-11-13)
Article
Open AccessThis paper presents the implementation of a custom-made virtual power plant model in OpenDSS. The goal is to develop a model adequate for time-driven power flow calculations in distribution systems. The virtual power plant ... -
Volition-adaptive control for gait training using wearable exoskeleton: preliminary tests with incomplete spinal cord injury individuals
(2018-01-03)
Article
Open AccessBackground Gait training for individuals with neurological disorders is challenging in providing the suitable assistance and more adaptive behaviour towards user needs. The user specific adaptation can be defined based on ... -
Impact of clock drifts on communication-free secondary control schemes for inverter-based islanded microgrids
(Institute of Electrical and Electronics Engineers (IEEE), 2017-11-13)
Article
Restricted access - publisher's policyIEEE In inverter-based microgrids, individual inverters operate usually with its own digital processor. The clocks used to generate the time signals of these processors differ from each other due to clock drifts. This paper ... -
Robust cardiac motion estimation using ultrafast ultrasound data: a low-rank topology-preserving approach
(2017-06-21)
Article
Open AccessCardiac motion estimation is an important diagnostic tool for detecting heart diseases and it has been explored with modalities such as MRI and conventional ultrasound (US) sequences. US cardiac motion estimation still ... -
Secondary switched control with no communications for islanded microgrids
(Institute of Electrical and Electronics Engineers (IEEE), 2017-05-12)
Article
Open AccessFlexibility and reliability of AC microgrids are enhanced by reducing the dependence on communications in multi-layer hierarchical control. In this sense, this paper presents a secondary control with no communications for ... -
Els sistemes encastats: impacte i reptes de futur
(Institut d'Estudis Catalans (IEC), 2017)
Article
Open AccessS’analitza l’impacte que tenen els moderns sistemes electrònics encastats en diferents àmbits, com són la societat, l’àmbit industrial i l’educació. Es presenta una breu definició del que és un sistema encastat i es donen ... -
Performance evaluation of secondary control policies with respect to digital communications properties in inverter-based islanded microgrids
(Institute of Electrical and Electronics Engineers (IEEE), 2016-09-12)
Article
Open AccessA key challenge for inverted-based microgrids working in islanded mode is to maintain their own frequency and voltage to a certain reference values while regulating the active and reactive power among distributed generators ... -
On gait analysis estimation errors using force sensors on a smart rollator
(2016-11-01)
Article
Open AccessGait analysis can provide valuable information on a person’s condition and rehabilitation progress. Gait is typically captured using external equipment and/or wearable sensors. These tests are largely constrained to specific ... -
Control of an ambulatory exoskeleton with a brain–machine interface for spinal cord injury gait rehabilitation
(2016-08-03)
Article
Open AccessThe closed-loop control of rehabilitative technologies by neural commands has shown a great potential to improve motor recovery in patients suffering from paralysis. Brain–machine interfaces (BMI) can be used as a natural ... -
Improving the performance of input interfaces through scaling and human motor models
(2016)
Article
Open AccessThe performance of interfaces is affected by human factors, which vary from one person to another, and by the inherent characteristics of the various devices involved. A set of techniques has been studied in order to ...
