Devolatilization predicting model based on coal heterogeneous chemical structure from micro-Raman spectroscopy with neural network

This study proposes a novel devolatilization model based on a convolutional neural network (CNN), employing quantified coal chemical structure features as input. Initially, a reliable method was developed to quantify the average/heterogeneous properties of coal structures using high-resolution micro-Raman spectroscopy. The evolution of chemical structure with increasing coal rank was investigated

On uniform recurrence for hyperbolic automorphisms of the 2-dimensional torus

We are interested in studying sets of the form U ( α ) := { x ∈ X : ∃ M = M ( x ) ⩾ 1 such that ∀ N ⩾ M , ∃ 1 ⩽ n ⩽ N such that d ( T n x , x ) ⩽ | λ | − α N } , where ( X , T , d ) is our metric dynamical system and | λ | > 1 . Although many results exist for the one dimensional case, not as many are known for systems in higher dimensions and especially in the hyperbolic case. We consider X = T 2

Exploring the evolution of magnesium oxidation mechanisms by density functional theory

Magnesium (Mg) is an abundant metal which has been used in aviation, medicine, hydrogen energy storage, etc. However, Mg can be rather reactive, and therefore an improved understanding of corrosion and oxidation mechanisms can enhance the efficiency of these processes to control and widen applications. The study presented here investigates the mechanisms of oxidation from the initial to full monol

Influence of friction material composition on airborne wear particle emissions from dry clutches

Airborne wear particle emissions from dry clutches have been investigated in terms of particle mass and number concentration, size distribution, and chemical composition of a single clutch material. This paper presents a detailed continuation of the investigation. Clutch plates of two different friction materials, i.e., from different manufacturers but for the same automobile applications, are tes

Truly supercritical trade-offs for resolution, cutting planes, monotone circuits, and Weisfeiler-Leman

We exhibit supercritical trade-off for monotone circuits, showing that there are functions computable by small circuits for which any small circuit must have depth superlinear or even super-polynomial in the number of variables, far exceeding the linear worst-case upper bound. We obtain similar trade-offs in proof complexity, where we establish the first size-depth trade-offs for cutting planes an

Study of the use of property probes in an educational setting

Context Developing compilers and static analysis tools (“language tools”) is a difficult and time-consuming task. We have previously presented property probes, a technique to help the language tool developer build understanding of their tool. A probe presents a live view into the internals of the compiler, enabling the developer to see all the intermediate steps of a compilation or analysis rather

Code review as decision-making : building a cognitive model from the questions asked during code review

Code review is a well-established and valued practice in the software engineering community contributing to both code quality and interpersonal benefits. However, there are challenges in both tools and processes that give rise to misalignments and frustrations. Recent research seeks to address this by automating code review entirely, but we believe that this risks losing the majority of the interp

Flow uniformity inside the drying chamber of a heat exchanger-based solar dryer : numerical analysis with smoke flow visualization as experimental validation

Solar drying technologies have emerged as efficient and user-friendly solutions for food drying processes, particularly in regions with limited access to electricity and high post-harvest losses. These technologies offer a sustainable alternative to conventional drying methods. However, one of the key challenges limiting their effectiveness is the non-homogeneous airflow inside the drying chamber,

Experimental study on hysteresis during cyclic injection in hierarchical porous media

Cycle injection schemes are often encountered in underground hydrogen storage (UHS), and the involved hysteresis directly impacts storage and extraction efficiency. The geological formation generally has hierarchical features containing multiple-level pore sizes. Nevertheless, we still lack a comprehensive understanding of this phenomenon and the pore-scale mechanism behind the geometry affects sa

Stable across regimes : A mixed DG method for Darcy–Brinkman–Stokes type flows

Hydromechanical models of Darcy–Brinkman–Stokes type consider mass- and momentum conservation of an incompressible fluid on a domain with varying permeability. They include the two important limits of free flow governed by the classical Navier–Stokes equations and porous Darcy flow. The conceptual simplicity makes the model attractive from a modeling perspective, but any numerical solution procedu

The synergistic integration of biologics and additive manufacturing (AM) technologies has catalyzed groundbreaking advancements in spinal surgery. These innovations address persistent challenges, such as optimizing fusion outcomes, enhancing tissue regeneration, and achieving precise anatomical compatibility. Biologics have transformed spinal fusion by facilitating bone formation and promoting ost

Community of place or community of interest : challenging the role of citizen engagement and proximity in energy communities in Sweden

There is an ongoing debate about what should be considered an energy community (EC), particularly in terms of citizen engagement and the proximity of community members to renewable energy production. The type of EC that exclusively engages with actors in a certain geographical location is defined as a community of place (COP). In contrast, communities of interest (COI) do not limit membership to t

Securing reconfigurable scan networks against data sniffing and data alteration attacks

It is common for a system integrator to make use of third party intellectual property (IP) blocks from multiple vendors in the design of a circuit. These IPs may include test features, known as instruments, which are connected to a reconfigurable scan network, such as an IEEE Std. 1687 (IJTAG) network, for efficient on-chip integration and communication.Using third party instruments this way becom
