Controlling the Oxygen Defects Concentration in a Pure BiFeO3 Bulk Ceramic

BiFeO ₃ is a multiferroic material with a perovskite structure that has a lot of potential for use in sensors and transducers. However, obtaining pure single-phase BiFeO ₃ ceramic with a low electrical conductivity via solid-state reactions remains a problem that limits its application. In this work, the suppression of...

TiEMPO: Open-source time-dependent end-To-end model for simulating ground-based submillimeter astronomical observations

The next technological breakthrough in millimeter–submillimeter astronomy is three-dimensional imaging spectrometry with wide instantaneous spectral bandwidths and wide fields of view. The total optimization of the focal-plane instrument, the telescope, the observing strategy, and the signal-processing software must enable efficient removal...

TerriStories. Literary Tools for Capturing Atmosphere in Architectural Pedagogy

By recognizing the potential of literary language in the description of architectural atmospheres, this contribution aims to confront the shortcomings of conventional pedagogical approaches in architecture that often fail to provide an in-depth understanding of the experiential aspects of place. To contribute to the development of appropriate...

Land Surface Processes Create Patterns in Atmospheric Residence Time of Water

Recent studies determined the residence time of moisture in the atmosphere to be 8–10 days but with large spatial and temporal differences. An unexplained daily cycle in the probability density function (PDF) of the residence time of land evaporation was observed, which was not present for oceanic evaporation. Moreover, the PDF of atmospheric...

Toward Turbulence-Resolving Weather and Climate Simulation

De vorige eeuw was getuige van de opkomst van numerieke weer- en klimaatmodellen. Weersvoorspelling, voorheen een empirische procedure gebaseerd op de persoonlijke ervaring van de meteoroloog, ontwikkelde zich tot een wetenschappelijke methode om de toekomstige toestand van de atmosfeer te voorspellen op basis van de huidige toestand en tendens....

Characterization of architectural and urban atmospheres in 'grands ensembles" (large-scale housing estates), built in France of the 1950s en 1973s

This paper introduces results of three case-studies of large-scale housing estates situated in Nantes (France): Dervallières (1952/1965), Breil Malville (1955/1967) and Malakoff (1967/1971). The main objective of this “grands ensembles” study is to produce knowledge about their architectural and urban atmosphere characteristic. The atmosphere...

Perceptual effects of overlapping curved glass

The application of glass in contemporary architecture explores perceptual phenomenon that intentionally change the way we experience space. SANAA'S recent work uses glass in a radical way, proposing a renewed approach to transparency. The Toledo Glass Pavilion, with most spaces defined by glass walls, presents an intense visual experience. The...

The inaudible symphony: On the detection and source identification of atmospheric infrasound

Sound becomes inaudible if it consists of frequencies lower than 20 Hz, i.e. the human hearing threshold, and is called infrasound. Low frequency acoustic signals were first discovered after the eruption of the Krakatoa (Indonesia) in 1883. Due to its low frequency content, this infrasound traveled up to seven times around the globe while...
