Dynamic Characterization of Thermocouples under Double-Pulse Laser-Induced Thermal Excitation

open access: yesSensors, 2023
This study investigated the dynamic characteristics of thermocouples by using double-pulse laser excitation for dynamic temperature calibration under extreme conditions.

Tertiles and the time constant

open access: yes, 2020
We consider planar first-passage percolation and show that the time constant can be bounded by multiples of the first and second tertiles of the weight distribution.

Supernovae Ia Constraints on a Time-Variable Cosmological "Constant" [PDF]

open access: yes, 1999
The energy density of a scalar field $\phi$ with potential $V(\phi) \propto \phi^{-\alpha}$, $\alpha > 0$, behaves like a time-variable cosmological constant that could contribute significantly to the present energy density. Predictions of this spatially-

Influence of the Thermometer Inertia on the Quality of Temperature Control in a Hot Liquid Tank Heated with Electric Energy

open access: yesEnergies, 2020
This paper presents the medium temperature monitoring system based on digital proportional–integral–derivative (PID) control. For industrial thermometers with a complex structure used for measuring the temperature of the fluid under high pressure, the ...

A constant-time algorithm for middle levels Gray codes [PDF]

open access: yes, 2017
For any integer~$n\geq 1$, a \emph{middle levels Gray code} is a cyclic listing of all $n$-element and $(n+1)$-element subsets of $\{1,2,\ldots,2n+1\}$ such that any two consecutive sets differ in adding or removing a single element.

Time-dependent cosmological constant in the Jackiw-Teitelboim cosmology [PDF]

open access: yes, 2002
We study the obtainment of a time-dependent cosmological constant at D=2 in a model based on the Jackiw-Teitelboim cosmology. We show that the cosmological term goes to zero asymptotically and can induce a nonsingular behavior at the origin.Comment: 4 ...

Gas Dynamical Capillary Flowmeters of Small and Micro Flowrates of Gases

open access: yesEnergy Engineering and Control Systems, 2015
The possibility of application of glass capillary tubes (CTs) as sensors of small and micro flowrates of gases was justified. The accuracy of a number of CTs flowrate equations was analyzed on the basis of experimental studies of CTs flowrate ...

A constant-time algorithm for middle levels Gray codes [PDF]

open access: yes, 2019
For any integer $n\geq 1$ a middle levels Gray code is a cyclic listing of all $n$-element and $(n+1)$-element subsets of $\{1,2,\ldots,2n+1\}$ such that any two consecutive subsets differ in adding or removing a single element. The question whether such

Autocorrelation structure at rest predicts value correlates of single neurons during reward-guided choice

open access: yeseLife, 2016
Correlates of value are routinely observed in the prefrontal cortex (PFC) during reward-guided decision making. In previous work (Hunt et al., 2015), we argued that PFC correlates of chosen value are a consequence of varying rates of a dynamical evidence
