The Time Augmented Cobb-Douglas Production Function

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
The main objective of this paper is to propose and verify a time augmentation of the Cobb-Douglas production function parameters which should be able to capture changing conditions over time.

Generating Functions of Timed Languages [PDF]

open access: yes, 2012
In order to study precisely the growth of timed languages, we associate to such a language a generating function. These functions (tightly related to volume and entropy of timed languages) satisfy compositionality properties and, for deterministic timed regular languages, can be characterized by integral equations. We provide procedures for closed-form

Feel the Time. Time Perception as a Function of Interoceptive Processing

open access: yesFrontiers in Human Neuroscience, 2018
The nature of time is rooted in our body. Constellations of impulses arising from the flesh constantly create our interoceptive perception and, in turn, the unfolding of these perceptions defines human awareness of time.

Physical healing as a function of perceived time

open access: yesScientific Reports, 2023
In this study we wounded study participants following a standardized procedure and manipulated perceived time to test whether perceived time affected the rate of healing.

On the Structure of the Minimum Time Function

open access: yesSIAM Journal on Control and Optimization, 2010
A minimum time problem with a nonlinear smooth dynamics and a target satisfying an internal sphere condition is considered. Under the assumption that the minimum time $T$ be continuous and the normal cone to the hypograph of $T$, $N_{hypo(T)}$, be pointed, we show that $hypo(T)$ is $\varphi$-convex, i.e., satisfies a strong external sphere condition ...

Dynamic prediction on goaf surface subsidence for the last two periods based on the Erf time function

open access: yesMeitian dizhi yu kantan
BackgroundThe surface subsidence induced by coal seam mining represents a continuous dynamic evolution process. Constructing a full-time perdition model for surface subsidence in goafs holds significant theoretical and practical values for the rational ...

Prescribed-Time Fractional Order Control of DWR via Time-Varying Scaling Function

open access: yesInternational Journal of Rotating Machinery, 2023
This study focuses on a differential wheeled robot’s (DWR) prescribed-time fractional order position control. Firstly, based on the kinematic model of DWR, a distance-related orientation error is designed using the inverse sine function.

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...
