Abstract:

Summary This paper gives an analysis of the Thomas and Windle model (Thomas and Windle 1982) to determine its usefulness for describing anomalous diffusion of CO2 in coal and its relation to matrix swelling. In addition, a finite-element description for this model is derived. For reasons of easy reference, a shortened derivation of the Thomas and Windle model is presented, which was originally derived to describe diffusion in polymers. The derivation includes the surface saturation effects proposed by Hui et al. (1987a, 1987b). Because the cumulative sorption showed tα behavior with α &gt;

Abstract:

The symplectic algorithm can maintain the symplectic structure and intrinsic properties of the system, its cumulative error is small and suitable for multi-step calculation. At present, the widely accepted symplectic operators are obtained by solving the Hamilton equation based on artificial definitions and assumptions in advance. There are inevitable dispersion errors. We solve the equation by pure mathematical derivation without any artificial limitations and assumptions. The way to accurately obtain high-precision symplectic operators greatly reduces the dispersion error from the beginning.

Abstract:

To improve the speed observation accuracy of the bearingless induction motor (BL-IM) and achieve its high-performance speed sensorless control, an improved sliding mode variable structure model reference adaptive system speed identification method based on sigmoid function (sigmoid-VS-MRAS) is proposed. Firstly, to overcome the problem of initial values and cumulative errors in the pure integration link of the reference flux-linkage voltage model, the rotor flux-linkage reference voltage model has been improved by using an equivalent integrator instead of the pure integration link.

Abstract:

This study investigates the effect of UV aging on the hardness properties of hybrid composite materials configured with glass and aramid fibers in four designs: pure glass fiber (S1), pure aramid fiber (S4), and two hybrid structures (S2 and S3) with varied fiber layering. Samples were exposed to UV light for 0, 20, and 40 days, and hardness values were recorded to evaluate how UV exposure and fiber hybridization influence material durability. Initially, the pure aramid composite (S4) exhibited the highest hardness at 28 HV, a 26.13% increase over the pure glass configuration (S1) at 22.2 HV.

Abstract:

The structures of social networks with power laws have been widely investigated. People have a great interest in the scale-invariant generating mechanism. We address this problem by introducing a simple model, i.e., a heuristic probabilistic explanation for the occurrence of a power law. In particular, the proposed model can be used to explain the generative mechanism that leads to the scale-invariant of the degree distribution with a power exponent of τ>2. Furthermore, a stochastic model (the pure birth points process) is used to describe the cumulative growth trend of edges of a temporal

Lamella flanges (Fig. 1) have lately grown popular with the designers of steel bridges –in their belief that these flanges provide us with the possibility of avoiding very thick flange plates in steel bridge structures. This belief is based on the assumption that the lamellas are perfectly plane and, therefore, in perfect contact everywhere, so that the loading from one lamella is transmitted into the other via pure compression, and that the perfect interaction of both lamellas is materialized by means of boundary fillet welds connecting both of the two lamellas.

Abstract:

Carbon mineralization in soil increased significantly due to additions of pure azadirachtin and powdered leaves and fruits of Melia azedarach L. under in vitro incubation for 30 days at 28°C. Cumulative respired C(CO2) clearly increased with incubation time in all treatments except in soil mixed with pure azadirachtin (p < 0.001). Carbon mineralization ratio in soils mixed with single doses of powdered leaf and fruit were significantly higher than the other doses tested.

Abstract:

Safe and effective conflict resolution is critical for survival and reproduction. Theoretical models describe how animals resolve conflict by assessing their own and/or their opponent's ability (resource holding potential, RHP), yet experimental tests of these models are often inconclusive. Recent reviews have suggested this uncertainty could be alleviated by using multiple approaches to test assessment models. The mantis shrimp Neogonodactylus bredini presents visual displays and ritualistically exchanges high-force strikes during territorial contests. We tested how N. bredini contest dynamic

It would not be an embellishment to say that folklore traditions connect people and nations through invisible lines. One can see the connectivity as the integrity of intimacy, solidarity and mutual understanding among nations of the world. Roaming the fairy tales orally among people entire the world as a form of that solidarity caused them to become an inseparable part of every nation’s folklore traditions. Therefore, studying fairy tales of nations from a theoretical, cultural and philosophical point of view, comparing and identifying the similar and differential lines can be the contin

Abstract:

Abstract The micro-arc oxidation coating of pure titanium was tested by mercury intrusion porosimetry (MIP), and the porosity were corrected by the proportion of coating volume, and finally a more accurate coating porosity was obtained. At the same time, the fractal dimension of pore structure was calculated by linear regression equation using mercury intrusion data. The results show that: the traditional image method is limited to the statistics of the pore area on the two-dimensional plane, while the MIP can not only obtain the average pore size and pore size distribution of the sample, but

Abstract:

AbstractWe investigate purity within the Frobenius category of Gorenstein flat cotorsion modules, which can be seen as an infinitely generated analogue of the Frobenius category of Gorenstein projective objects. As such, the associated stable category can be viewed as an alternative approach to a big singularity category, which is equivalent to Krause's when the ring is Gorenstein. We study the pure structure of the stable category, and show that it is fundamentally related to the pure structure of the Gorenstein flat modules. Following that, we give conditions for extension of scalars to pres

Abstract:

The variability of longitudinal bending strength of timber beams due to the presence of knots and other defects is analyzed. The weak zones model of timber beam bending strength used in the analysis consists of short weak zones (knots or group of them) and strong sections of clear wood. The load bearing capacity of timber beams is defined as an extreme (minimum) value problem or as a first downcrossing problem. Assuming a marked Poisson random field with zero correlation between all random variables, cumulative probability distribution functions of the load carrying capacity of timber beams we

Abstract:

AbstractHeterogeneous metallic structures constitute a novel class of materials with excellent mechanical properties. However, the existing process for obtaining heterostructures from a single material does not meet large-scale industrial requirements. In this study, a pure copper heterostructured laminate (HSL) composed of a surface elongated-grain layer and a central equiaxed-grain layer was fabricated by rolling bonding and annealing. To study the effect of the interface on the mechanical properties of gradient-structured materials, both laminate metal composite (LMC) and non-composite lami
