Performance enhancement of renewable energy systems subject to units’ degradation and performance dependence

open access: yesEnergy Reports, 2020
A performance enhancement model for multi-state renewable energy systems is introduced and developed in this paper. This model’s objective is to provide a maintenance decision support, taking into account units’ degradations and system interdependencies.

Universal properties of spaces of generalized functions

open access: yesJournal of Mathematical Analysis and Applications
By means of several examples, we motivate that universal properties are the simplest way to solve a given mathematical problem, explaining in this way why they appear everywhere in mathematics. In particular, we present the co-universal property of Schwartz distributions, as the simplest way to have derivatives of continuous functions, Colombeau ...

First-generation students’ underperformance at university: the impact of the function of selection [PDF]

open access: yesFrontiers in Psychology, 2015
According to recent research, university not only has the role to educate and train students, it also has the role to select the best students. We argue that this function of selection disadvantages first-generation students, in comparison with continuing-generation students.

Analysis of the amplitude form of the quantum hash function

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2023
In this article, the properties of quantum hash functions are further explored. Previous findings show that so-called small-bias sets (special subsets of the set of elements of a cyclic group) generate a “phase” quantum hash function. Here, it was proved

Dynamic Reliability Assessment Framework for Integrated Energy Systems Based on the Improved Universal Generating Function

open access: yes, 2021
With the development of science and technology in the field of energy, the concept of Integrated Energy System (IES) has attracted more and more researchers' attention. However, it is difficult to evaluate the reliability of the coupled energy system due

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Generalized Universality for Compositions of the Riemann Zeta-Function in Short Intervals

open access: yesMathematics, 2023
In the paper, the approximation of analytic functions on compact sets of the strip {s=σ+it∈C∣1/2<σ<1} by shifts F(ζ(s+iu1(τ)),…,ζ(s+iur(τ))), where ζ(s) is the Riemann zeta-function, u1,…,ur are certain differentiable increasing functions, and F is a certain continuous operator in the space of analytic functions, is considered.
