In this paper, we introduce new weaker forms of locally closed sets called binary semi-locally closed, binary locally semi-closed sets, and binary generalized locally semi-closed sets and study their relations with the existing ones. We also try to establish the conditions under which these weaker forms coincide with one another. Further it is established that in a particular space, all the weaker forms of binary locally closed sets coincide with P(X,Y), the power set of (X,Y).

In this study, we have employed the highly significant hyperbolic tangent (tanh) method to conduct an in-depth analysis of nonlinear coupled KdV systems of partial differential equations. In comparison to existing sophisticated approaches, this proposed method yields more comprehensive exact solutions for traveling waves without requiring excessive additional effort. We have successfully applied this method to two examples drawn from the literature of nonlinear partial differential equation systems.

In this paper, we establish a new concentration inequality and almost complete convergence of the value of the process of autoregressive Hilbertian of order one (ARH (1)), which directly stems from works of Serge Guillas, Denis Bosq, that is defined by X_t= ρ(X_(t- 1)) +ζ_t; t∈ Z where the random variables are all Hilbertian, ρ is a linear operator on a space of separable Hilbert and ζ_t which constitute a widely orthant dependent error (WOD, in short) after recalling some results on the finite-dimensional model of this type, we introduce the mathematical and statistical tools which will be used afterwards. Then we build an estimator of the operator and we establish its asymptotic properties.

The effects of friction on polymeric materials are quite difficult to explain due to the micro and macroscopic interactions of the friction coupling surfaces, which slide over each other. The friction and wear behavior of surfaces in sliding motion can be considered important design criteria. By adding different concentrations of reinforcing agent to the base material, the tribological performance of surfaces in sliding motion can be obtained. The experimental study was carried out on a pin-on-disc type tribological stand under dry friction conditions. The friction and wear behavior was analyzed for two base materials (PTFE and PA66) and the same glass fiber reinforced materials (PTFE + 25% fiber-glass and PA66+GF30). The tests were carried out at different sliding speeds and loading forces, v1=0.20 m/s, v2=0.50 m/s, v3=0.75 m/s and loading forces, Fn1=1.0 N, Fn2=2.5 N, Fn3=5.0 N over a friction length of 5000 mm. Research has shown that the coefficient of friction decreases with increasing loading force. Tests have shown that a high value of the friction coefficient does not mean a high wear rate, the wear rate values are between 10-12 and 10-15 m2/N. TheL(1) presences of the reinforcing agent in the base material have a significant importance on the friction and wear behavior under the action of operating factors (load, sliding speed).
摩擦对聚合物材料的影响是很难解释的，因为摩擦耦合表面的微观和宏观相互作用，它们相互滑动。表面在滑动运动中的摩擦和磨损行为可以被认为是重要的设计准则。通过在基材中添加不同浓度的增强剂，可以获得滑动运动表面的摩擦学性能。在干摩擦条件下对销盘式摩擦架进行了试验研究。分析了两种基材(PTFE和PA66)和同一种玻璃纤维增强材料(PTFE + 25%玻璃纤维和PA66+GF30)的摩擦磨损性能。在不同的滑动速度和加载力(v1=0.20 m/s, v2=0.50 m/s, v3=0.75 m/s)和加载力(Fn1=1.0 N, Fn2=2.5 N, Fn3=5.0 N)下进行试验，摩擦长度为5000 mm。研究表明，摩擦系数随加载力的增大而减小。试验表明，摩擦系数高并不意味着磨损率高，磨损率值在10-12 ~ 10-15 m2/N之间。(1)增强剂在基材中的存在对操作因素(载荷、滑动速度)作用下的摩擦磨损性能有显著影响。

The Greco-Roman stucco masks are of great historical, artistic and religious importance. According to the restoration-conservation strategies, the detailed mineral characterization of artifacts is an important step that facilitates the selection of appropriate restoration procedures. Different characterization techniques such as USB digital microscope, scanning electron microscopy–energy dispersive X-ray analysis, X-ray diffraction analysis (XRD), thermal analysis (DTA/DTG), Fourier transform infrared and micro-Raman spectroscopies were used. The results indicated that gypsum is the main component of the stucco mask. As well, calcite was found as an impurity or an addition together with halite and anhydrite as deterioration products. The iron nail corrosion was the reason for a notable discoloration to the stucco mask. FTIR analysis confirms that animal glue is the adhesive material used for the reassembly of the mask. The used pigments for painting the mask are hematite for red-orange color, mixture of hematite and magnetite for brown color and mixture of gypsum and hematite for the white brown color.

In this work, we obtain the exact solutions of negative-order forms for KDV-Calogero-Bogoyavlenskii-Schiff equation (nKdV-nCBS) with conformable fractional derivative by using method. Chain rule and wave transform are used for transforming nonlinear fractional partial differential equation into nonlinear integer order ordinary differential equation. By this way, we don’t need any normalization or reduction formulas which have complex calculation procedures. Moroever 3D graphical simulations are presented to show the geometrical behaviour of derived solutions.

This study describes a low-cost and easy to deploy gait monitoring system that uses an ESP32 microcontroller and an ICM-20948 module. The ESP32 microcontroller collects data from the ICM-20948 module and these data are used to train a convolutional neural network (CNN) to classify gait patterns into two categories: normal and pathological. The results show that the system can achieve a high accuracy for binary gait classification, being able to correctly classify 97.05% of the normal gait samples and 84.54% of the pathological gait samples. The power consumption of the devive was measured using a calibrated and dual-acquisition digital multimeter. The estimated operating time was around 12 hours, with a battery capacity of 1800 mAh LiPo type. Therefore, it could be used to track the gait of patients with neurological disorders or to assess the effectiveness of gait rehabilitation treatments.

There are many common combination methods for solving fractional differential equations. In this work, we propose a new technique called Adomian decomposition transform method (ADTM) in order to provide a new approximate series solution of fractional order Bratu-type differential equations. The fractional order derivative is described in the Caputo sense. The ADTM is a combination of two powerful methods, the Jafari transform method and Adomian decomposition method. For accelerating the convergence of ADTM when used for these equations, we replace the nonlinear terms by their Taylor expansion. To demonstrate the efficiency and validity of the proposed method, four numerical examples are presented and we compare our obtained results with the analytical results. Finally, the numerical results obtained are represented graphically using MATLAB software.
