Economic Optimization of a Thermal Solar Power Plant That Operates With a HRB Cycle by Improving the Operation Schedule

open access: yesSolarPACES Conference Proceedings, 2023
In this paper, two solutions are proposed to increase the sales revenue of a pre-sized solar thermal power plant (STPP) that operates with a Hybrid Rankine Brayton cycle (HRB) by changing the reference operating parameters.

Distance between quantum states in presence of initial qubit-environment correlations: a comparative study [PDF]

open access: yesPhys. Rev. A 84, 032120 (2011), 2011
The time evolution of the trace distance between two states of an open quantum system may increase due to initial system-environment correlations, thus exhibiting a breakdown of distance contractivity of the reduced dynamics. We analyze how the time evolution of the distance depends on the chosen distance measure.

On the estimation of latent distances using graph distances [PDF]

open access: yesElectronic Journal of Statistics, 2021
We are given the adjacency matrix of a geometric graph and the task of recovering the latent positions. We study one of the most popular approaches which consists in using the graph distances and derive error bounds under various assumptions on the link function. In the simplest case where the link function is proportional to an indicator function, the

A Note on Statistical Distances for Discrete Log-Concave Measures [PDF]

open access: yesarXiv, 2023
In this note we explore how standard statistical distances are equivalent for discrete log-concave distributions. Distances include total variation distance, Wasserstein distance, and $f$-divergences.

Collateralization and distance

open access: yesJournal of Banking & Finance, 2019
Abstract This paper examines how collateralization in small business lending varies with bank-borrower proximity. Our analysis establishes a robust inverse relationship between distance and collateral: Borrowers located in the vicinity of the bank face higher collateral requirements.

Algebraic lattice constellations: bounds on performance [PDF]

open access: yes, 2002
In this work, we give a bound on performance of any full-diversity lattice constellation constructed from algebraic number fields. We show that most of the already available constructions are almost optimal in the sense that any further improvement of ...

Academic Performance in Distance Education: Quizzes as a Moderator Variable and Students’ Perception and Expectation through Linguistic Analysis

open access: yesOnline Learning, 2022
This study sheds light on the relation between assessment modalities and student behavior through linguistics styles, and academic performance. First, we examine the effect of assessment modalities (self-evaluation quizzes and summative quizzes) on ...

A gravitino distance conjecture [PDF]

open access: yesJournal of High Energy Physics, 2021
Abstract We conjecture that in a consistent supergravity theory with non-vanishing gravitino mass, the limit m3/2 → 0 is at infinite distance. In particular one can write Mtower ~ $$ {m}_{3/2}^{\delta } $$ m 3 /

Individual Crafting, Collaborative Crafting, and Job Satisfaction: The Mediator Role of Engagement

open access: yesJournal of Work and Organizational Psychology, 2019
Most theories of job crafting understand the term to refer to an individual activity, and only a few studies have focused on collaborative job crafting. The present study has two aims.
