A 4-GHz Low-Power, Multi-User Approximate Zero-IF FM-UWB Transceiver for IoT
(2019)This paper presents a 4-GHz FM ultra-wideband (UWB) transceiver designed for the Internet of Things and body area network applications. Robustness to interferers and low power spectral density allow FM-UWB to coexist with ... -
A comparative performance analysis of stand-alone, off-grid solar-powered sodium hypochlorite generators
(2019)Sodium hypochlorite (NaClO) is a chemical commodity widely employed as a disinfection agent in water treatment applications. Its production commonly follows electrochemical routes in an undivided reactor. Powering the ... -
A D-optimal design to model the performances of dressings and devices for negative pressure wound therapy
(2016)A D-optimal design was used to identify and model variables that affect the transit time of wound exudate through an illustrative dressing used for negative pressure wound therapy. Many authors have addressed the clinical ... -
A Kerr polarization controller
(2022-01-19)Kerr-effect-induced changes of the polarization state of light are well known in pulsed laser systems. An example is nonlinear polarization rotation, which is critical to the operation of many types of mode-locked lasers. ... -
A Low-Cost USB-Compatible Electronic Stethoscope Unit for Multi-channel Lung Sound Acquisition
(2020)The diagnosis of respiratory diseases relies largely on auscultation. To further improve the diagnosis quality, continuous acoustic multi-channel surveillance of the airways is highly desirable. The application of multiple ... -
A microphotonic astrocomb
(2019-01)A microphotonic astrocomb is demonstrated via temporal dissipative Kerr solitons in photonic-chip-based silicon nitride microresonators with a precision of 25?cm?s–1 (radial velocity equivalent), useful for Earth-like ... -
A Novel Chewing Detection System Based on PPG, Audio, and Accelerometry
(2017)In the context of dietary management, accurate monitoring of eating habits is receiving increased attention. Wearable sensors, combined with the connectivity and processing of modern smart phones, can be used to robustly ... -
A novel smartphone app for blood pressure measurement: a proof-of-concept study against an arterial catheter
(2022-06-21)Smartphones may provide a highly available access to simplified hypertension screening in environments with limited health care resources. Most studies involving smartphone blood pressure (BP) apps have focused on validation ... -
A passivating contact concept compatible with a short thermal treatment
(2018)In this study we present a boron-doped silicon carbide layers as a hole-selective contact which is compatible with short annealing time (typically < 1 minute) as the one used for firing of metal pastes. The application of ... -
A passivating contact for silicon solar cells formed during a single firing thermal annealing
(2018)Passivating contacts are indispensable for achieving high conversion efficiency in crystalline-silicon solar cells. Their realization and integration into a convenient process flow have become crucial research objectives. ... -
A Photothermal Spectrometer for Fast and Background-Free Detection of Individual Nanoparticles in Flow
(2017)Sensitive detection and quantification of individual plasmonic nanoparticles is critical in a range of applications in the biological, nanomaterials, and analytical sciences. Although a wide range of techniques can be ... -
A Physically-Based Electrical Model for Lithium-Ion Cells
(2019)Prediction of battery performance is essential in assessing the technical and economic viability of battery systems. We present a novel impedance-based model of a lithium-ion cell that accounts for the dynamic response of ... -
A real-time optimal inverse planning for Gamma Knife radiosurgery by convex optimization: description of the system and first dosimetry data
(2018)OBJECTIVE The authors developed a new, real-time interactive inverse planning approach, based on a fully convex framework, to be used for Gamma Knife radiosurgery. METHODS The convex framework is based on the precomputation ...
