Buckling is a condition where an object bent due to the application of compression (compressive) load on object. often occurs in thin-walled structures such as plates. This study aims determine buckling strength isotropic and quasi-isotropic The method used Finite Element Method (MEH). material uses aluminum 2024-T3, while carbon/epoxy T300-5208 with [0°/90°/45°/-45°]s laminate arrangement.

and tobacco smokers and 92 tobacco smokers with 81 non-smokers. They found a dose-response relationship between cannabis consumption and the degree of airways obstruction and hyperinflation. They estimated that one cannabis joint was equivalent to 2.5 cigarettes for the effect on forced expiratory volume in 1 s/forced vital capacity and to 6 cigarettes for the effect on specific airways conduct...

This study explores the issue of adaptive stabilization for a class high-order uncertain nonlinear systems with asymmetric output constraint and zero dynamics. By combining skillful Barrier Lyapunov Function (BLF) technique continuous feedback domination equipped group integral functions including nested sign functions, state stabilizer is established, which guarantees that closed-loop system’s...

Abstract This paper investigates the dynamic cooperative learning control for high‐order output‐feedback systems under output constraints. To avoid complex computation, we use a system transformation strategy in design. Only one neural network (NN) is employed to approximate unknown synthetic function each agent. Subsequently, NN‐based mechanism designed by introducing barrier Lyapunov (BLF). T...

The paper investigates the problem of adaptive finite-time robust stabilization for a set high-order uncertain nonlinear systems in presence asymmetric output constraint, dynamic uncertainty and complicated external disturbances. Via effectively integrating artful Barrier Lyapunov Function (BLF) conjunction with continuous control armed serial integral functions consisting embedded sign operati...

With the successful clinical trials, multifunctional glycoprotein bovine lactoferrin is gaining attention as a safe nutraceutical and biologic drug targeting cancer, chronic-inflammatory, viral and microbial diseases. Interestingly, recent findings that human lactoferrin oligomerizes under simulated physiological conditions signify the possible role of oligomerization in the multifunctional act...

Abstract In this paper, we look at a type of strict-feedback nonlinear systems that have neural adaptive finite-time command filtered control and full-state constraints. To begin with, indeterminate functions are estimated using the NN. The system’s capacity to detect unmeasurable states disturbances is done while composite observer, which significantly boosts anti-interference performance. Nex...

Edge detection algorithms have traditionally utilized the Gaussian Linear Filter (GLF) for image smoothing. Although GLF has very good properties in removing noise and unwanted artifacts from an image, it is also known to remove many valid edges. To cope with this problem, edge preserving smoothing filters have been proposed and they have recently attracted increased attention. In this paper, w...

The primary respiratory mechanism (PRM) as manifested by the cranial rhythmic impulse (CRI), a fundamental concept to cranial osteopathy, and the Traube-Hering-Mayer (THM) oscillation bear a striking resemblance to one another. Because of this, the authors developed a protocol to simultaneously measure both phenomena. Statistical comparisons demonstrated that the CRI is palpably concomitant wit...
