We compare the superconducting properties of 100 nm thick NbTiN films grown by reactive sputtering on silicon and flexible commercial polyimide. The samples are fabricated by co-sputtering using Nb and Ti targets at room...

Integrating deformable mirrors within the optical train of an adaptive telescope was one of the major innovations in astronomical observation technology, distinguished by its high optical throughput, reduced optical surf...

We present a new instrument composed of a large number of sub-electron noise SkipperCCDs operated with a two stage analog multiplexed readout scheme suitable for scaling to thousands of channels. New, thick, 1.35 Mpix se...

Abstract In this article an innovative method of studying and removing the resonances, inherently exhibit by some waveguide to microstrip transitions, is presented. By modeling an equivalent circuit, this new approach al...

Abstract This work presents the development of a reconfigurable frequency selective surface (RFSS) for application in the 2400-2483.5 MHz band, standard IEEE 802.11b/g/n (Wi-Fi). The proposed RFSS is based on the four-ar...

The PLN officer in charge of recording kWh meters is sometimes unable to photograph them because men discovered that the houses were unoccupied and their fences were locked. Due to these circumstances, the calculation of...

Abstract This paper presents an eyebolt structural fault detection system, based on the analysis of multiple electromagnetic parameters through a random forest classifier trained by both measurements and high-fidelity si...

Abstract In this work, measuring capabilities of a Sagnac Interferometer-based Distributed Optical Fiber Sensor (DOFS) system are demonstrated by comparing its results to a conventional amplitude-based Distributed Acoust...

Hybrid energy storage systems have shown promise in enhancing solar panel systems reliability and efficiency. However, managing the power distribution balance with multiple energy storage units remains a challenge. This ...

This study is a quantitative study that aims to a) describe the coordination of protection systems under abnormal conditions in the distribution network and b) to determine the selectiveity of protection systems in isola...

In this new normal era, universities, both private and public, have started to learn face-to-face. When collecting assignment reports, sometimes teachers or lecturers are unable to attend because of the hectic activity o...
