Exploratory Study on Carbon Dioxide Blends With Low‐GWP Working Fluids for Medium and High‐Temperature Heat Pumps Under Step Pressure

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates binary zeotropic mixtures of R744 (CO₂) blended with eco‐friendly refrigerants for medium‐high temperature heat pumps, comparing them with conventional R744/R134a systems. All mixtures meet 60–80 K temperature lift requirements under low‐temperature conditions. A genetic algorithm optimized system parameters using fixed

Quantum Carnot Bound from Petz Recovery Maps

Advanced Physics Research, EarlyView.
A quantum bound (ηP$\eta_P$, the Petz Limit) is derived for the efficiency (η$\eta$) of a heat engine utilizing two‐level quantum systems (qubits) as the working substance. This limit, based on Petz recovery maps, is stricter than the classical Carnot limit (ηC$\eta_C$) for irreversible cycles.

Efficient Dynamics: Reduced‐Order Modeling of the Time‐Dependent Schrödinger Equation

Advanced Physics Research, EarlyView.
Reduced‐order modeling (ROM) approaches for the time‐dependent Schrödinger equation are investigated, highlighting their ability to simulate quantum dynamics efficiently. Proper Orthogonal Decomposition, Dynamic Mode Decomposition, and Reduced Basis Methods are compared across canonical systems and extended to higher dimensions.

Modeling and parameter estimation for fractional large‐scale interconnected Hammerstein systems

Asian Journal of Control, EarlyView.
Abstract This paper addresses the challenge of modeling and identifying large‐scale interconnected systems exhibiting memory effects, hereditary properties, and non‐local interactions. We propose a fractional‐order extension of the Hammerstein architecture that incorporates Grünwald–Letnikov operators to capture complex dynamics through multiple ...

Inverse Coefficient Problem for Elliptic Hemivariational Inequality

, 2001
In this paper we consider the problem of identification of a discontinuous coefficient in elliptic hemivariational inequality. First we prove an existence theorem for an inverse problem and we establish the boundary homogenization result for the direct problem. Then we study the asymptotic behavior of the set of solutions to the inverse problem.

Pathways to employment: Subject choice, job requirements, and early employment outcomes for UK undergraduates

British Educational Research Journal, EarlyView.
Abstract Higher education in the United Kingdom has dramatically expanded in recent decades, along with questions about its effectiveness in preparing graduates for the labour market. With rising tuition fees and increasing competition for graduate jobs, many students opt to study ‘professional’ subjects—fields closely tied to specific professions ...

Socioeconomic and Indigenous school segregation in Australia: The role of institutional differentiation and fees

British Educational Research Journal, EarlyView.
Abstract School segregation is an international problem undermining the performance and equity of education systems. Australia's secondary schooling system offers international insights into the causes of segregation owing to it being one of the most segregated in the Organisation for Economic Co‐operation and Development, its long history of school ...

Potential of a digital parenting app to support parents of toddlers: Relations between the intensity of app use, language‐related parental self‐efficacy and the home literacy environment

British Educational Research Journal, EarlyView.
Abstract The home literacy environment (HLE) has a considerable influence on children's language development. How parents perceive their own parenting abilities (e.g., how well they encourage their children's language development) is particularly important when it comes to guiding their children appropriately through different stages of development ...
