The linear buckling behavior of functionally graded toroidal shell segments with corrugated core under axial compression using the first-order shear deformation theory is presented in this paper. The homogeneous technique is applied for shear deformable corrugated core. Approximate analytical solutions are assumed to satisfy the simply supported boundary conditions and the adjacent equilibrium criterion is applied to obtain closed-form relations of buckling loads.

In this paper, we investigate a novel downlink Small Cell (SC) system based on the Cell Free (CF) model, with the deployment of Unmanned Aerial Vehicles (UAVs) as Aerial Relay Stations (ARSs) simultaneously serving users in a specific area. The new SC model concept is expressed in the user-centric idea that the user will choose only one ARS with the best conditions for communication, and the concept of “cell" or “cell boundary" will no longer exist.

The Gronwall lemma and Poincaré type inequality will play a central role in our computational technique as well as of the paper. Studying the properties of solutions is important to determine the behavior of solutions over a long period of time. The obtained result particularly extends previous results for 2D NVS equations.

In this paper, the authors proposed a higher-order shear deformation theory for buckling and free vibration analysis of functionally graded sandwich plates. Equations of motion derived from Hamilton’s principle are established basing on a refined hyperbolic distribution of transverse shear stress which satisfies the traction free boundary conditions.

This research is built upon the determination of the Eigenpairs of one and two dimensional positive differential operators with periodic boundary conditions. The Schrödinger equation was solved for positive operators in both one and two dimensions. Fourier series were used to express the derivatives as the summation of Fourier terms. This led to a novel approach for the calculation of the eigenmodels of a perturbed potential well. The perturbation can be done via an electric field applied to the potential well.

This research develops a rich theoretical and empirical understanding of embeddedness by way of three dimensions (structural, relational and cultural), and investigates its implications for actors’ value co-creation behaviours and value-in-context outcomes. In addition, the research refines co-creation perspectives by examining a central boundary condition of co-creation processes. The data was collected in an online service environment and was analysed using structural equation modelling techniques.

Plasma facing components such as divertor receive huge heat load. Without proper solution to this problem, nuclear fusion reactor design would be impossible. In order to keep energy balance in the sensor, precious heat conduction model with proper boundary condition and initial condition must also be studied. Not only target temperature but also its time derivative need to be considered.
