Thermoelectric Radiation Detector Based on Superconductor-Ferromagnet Systems
2017
We suggest an ultrasensitive detector of electromagnetic fields exploiting the giant thermoelectric effect recently found in superconductor-ferromagnet hybrid structures. Compared with other types of superconducting detectors where the detected signal is based on variations of the detector impedance, the thermoelectric detector has the advantage of requiring no external driving fields. This is especially relevant in multipixel detectors, where the number of bias lines and the heating induced by them are an issue. We propose different material combinations to implement the detector and provide a detailed analysis of its sensitivity and speed. In particular, we perform a proper noise analysis…
Imperial straightening devices in disciplinary choices of academic knowledge production
2021
Abstract In this piece, the authors question whether critical language research, in its complex collection of researcher choices, is possible beyond the discursive imaginary of critical academic scholarship. In other words, how do (allegedly) anticolonial efforts re-orient towards contribution to the imperial record? We present three vignettes, through which we grapple with the notion that researcher choice exists within the solipsism of academia. In doing so, we frame research and scholarship as a collection of choices, which we believe are better understood as a collection of fraught dilemmas. These dilemmas recognize that all academic scholarship production and its processes are birthed …
Towards sustainable mobility : Transformative scenarios for 2034
2022
Highlights • Increasing the share of walking and cycling is one of the building blocks of sustainable mobility transformation. • We organised an online Delphi survey for 30 walking and cycling experts during the first wave of COVID-19 pandemic. • Disaggregative Delphi analysis is elaborated based on the systemic restructuring of qualitative data. • Transport experts’ views of the future are described in the form of five walking and cycling scenarios up to 2034. • The results can be used for strategic transport planning and policy, and for identifying instruments for walking and cycling promotion in urban areas. Increasing the share of walking and cycling is one of the building blocks of sus…
Encryption and Generation of Images for Privacy-Preserving Machine Learning in Smart Manufacturing
2023
Current advances in machine (deep) learning and the exponential growth of data collected by and shared between smart manufacturing processes give a unique opportunity to get extra value from that data. The use of public machine learning services actualizes the issue of data privacy. Ordinary encryption protects the data but could make it useless for the machine learning objectives. Therefore, “privacy of data vs. value from data” is the major dilemma within the privacy preserving machine learning activity. Special encryption techniques or synthetic data generation are being in focus to address the issue. In this paper, we discuss a complex hybrid protection algorithm, which assumes sequenti…

A synthesis of deimatic behaviour
2022
Deimatic behaviours, also referred to as startle behaviours, are used against predators and rivals. Although many are spectacular, their proximate and ultimate causes remain unclear. In this review we aim to synthesise what is known about deimatic behaviour and identify knowledge gaps. We propose a working hypothesis for deimatic behaviour, and discuss the available evidence for the evolution, ontogeny, causation, and survival value of deimatic behaviour using Tinbergen's Four Questions as a framework. Our overarching aim is to direct future research by suggesting ways to address the most pressing questions in this field. peerReviewed
Tietämätön opettaja demokratiakasvatuksessa
2021
Tämä artikkeli tutkii ranskalaisajattelija Jacques Rancièren älyjen tasa-arvon käsitettä sekä tasa-arvon periaatetta demokratiakasvatuksessa. Artikkelin kollaboratiivinen empiirinen aineisto koostuu 19 opettajaopiskelijan sekä heidän opettajanaan toimineen kirjoittajan autoetnografisista teksteistä yhden lukuvuoden mittaisen kurssin ajalta. Kirjoittajan kokoama ja kertoma moniääninen autoetnografinen tarina tuo esiin erilaisia näkökulmia opettajuuteen ja opettajaksi kasvamiseen, joita peilataan Rancièren ajatteluun. Artikkeli valottaa Rancièren filosofian antia demokratiakasvatukselle ja konkretisoi Rancièren käsitteitä. Lisäksi artikkeli jäsentää älyjen tasa-arvoa autoetnografisen tutkimus…

Se presentan tanto los supuestos teóricos y las implicaciones metodológicas que alimentan la implementación de prácticas autoevaluativas, como también, los resultados cualitativos obtenidos con una muestra de 150 …
Reconfigurable nonlinear response of dielectric and semiconductor metasurfaces
2021
Abstract Optically resonant dielectric and semiconductor metasurfaces are an emerging and promising area of nanophotonics and light–matter interaction at the nanoscale. Recently, active tuning of the linear response and nonlinear effects of these components has received an increasing amount of interest. However, so far these research directions have remained separated with only few sporadic works that study their combination beginning to appear in the literature. The evolution of nonlinear metasurfaces based on dielectric and semiconductor materials toward reconfigurable and dynamic components could potentially answer the demand of integrated on-chip components that realize essential functi…
Review of photoelastic image analysis applied to structural birefringent materials: glass and polymers
2015
Photoelasticity is particularly suitable for the analysis of the stress state in structural materials that are transparent and birefringent. Some techniques of digital photoelasticity (phase shifting and RGB) are applied to the analysis of stress field in two classes of structural materials. The first one consists of tempered glasses, such as those used in the automotive and architectural fields. The second one consists of thermoset polymers, typically used as matrices in fiber reinforced plastic structural composites. The birefringence of such resins is, in particular, exploited to investigate the development of swelling stresses and changes in fracture toughness as induced by water uptake…
