Low-Power Highly Robust Resistance-to-Period Converter

open access: yesSensors, 2018
This paper presents a novel structure of Resistance- to-Period (R-T) Converter highly robust to supply and temperature variations. Robustness is achieved by using the ratiometric approach so that complex circuits or high accuracy voltage references are ...

A Novel Response Factor-Based Method for In Situ Measurement of Wall Thermal Resistance

open access: yesBuildings, 2023
The heat flow meter method (HFM) is one of the most-used methods for the in situ measurement of wall thermal resistance. However, the standard HFM method has some issues: it is challenging to balance simplicity and accuracy in data analysis and the ...

On Measures Resisting Multifractal Analysis [PDF]

open access: yes, 2015
Any ergodic measure of a smooth map on a compact manifold has a multifractal spectrum with one point - the dimension of the measure itself - at the diagonal. We will construct examples where this fails in the most drastic way for invariant measures invariant under linear maps of the circle.

Force Control of SMA Springs Using RNNs

open access: yesIEEE Access
Shape memory alloys (SMAs), generally composed of nickel-titanium, have unique properties that enable them to transition from the martensite phase to the austenite phase when heated.

Measuring Resistance to Virus Infection [PDF]

open access: yesJournal of Hygiene, 1955
Dilution series of viruses often do not fit the exponential curve which they should fit if the usual assumptions of the theory of dilution series were true. Suppose the density of the virus suspension is λ, the average number of virus particles per unit volume of the inoculum (we suppose that unit volume is the amount actually used in inoculating the ...

Measuring Transpiration Resistance of Leaves [PDF]

open access: yesPlant Physiology, 1965
The transpiration process can be described physically, following Raschke (10), in terms of a resistance to diffusive and turbulent vapor flux in the external air, a similar diffusive resistance which results from the internal leaf geometry, inclusive of the stomata, and parallel to the latter, a resistance to vapor diffusion through the cuticle.
