High quality of service (QoS) requirements in multi-priority wireless sensor networks pose new challenges to the Internet of Things (IoT). In a multi-event wireless sensor network (MWSN), nodes generate different types of data packets with different priority such as urgent (high priority) or normal (low priority), with different traffic proportion.

This paper presents the free vibration and critical buckling analyses of porous plates based on the first-order shear deformation theory by the proposed three-node triangular element. The bending strain fields of the suggested element are enriched by the bubble node located at the centroid of the triangular element.

In this article, we explore the operation of the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol - a protocol compatible with low-energy sources and propose a solution to improve efficiency in wireless sensor networks. The simulation results show that our solution is better in terms of the number of packets reaching the base station and the average lifetime of the sensor nodes.

This study presents a novel application of mesh-free method using the smoothed-radial basis functions for the computational homogenization analysis of materials. The displacement field corresponding to the scattered nodes within the representative volume element (RVE) is split into two parts including mean term and fluctuation term, and then the fluctuation one is approximated using the integrated radial basis function (iRBF) method.

In this paper, a computational approach using a combination of the upper bound theorem and the bubbleenhanced quadrilateral finite element (FEM-Qi6) is proposed to evaluate bearing capacity factors of strip footing in cohesive-frictional soil. The new element is built based on the quadrilateral element (Q4) by adding a pair of internal nodes to solve the volumetric locking phenomenon.

We present a generalized three-variable high order shear deformation theory (THSDT) using isogeometric analysis (IGA) to analyze free vibration of functionally graded porous (FGP) plates reinforced by graphene platelets (GPLs) in this work. It is named as FGP-GPLs for a short. The proposed theory only has got three degrees of freedom (DOFs) per node as the same way of numerically solutions in three-dimensional (3D) solids.

We use the conditional granger causality framework to investigate the connectedness among the most globally traded currencies from three perspective namely node-wise, group-wise and system-wise connectedness. Empirically, Global currencies tend to form into communities based on connection strength and density. While more links are found for emerging market currencies, the G11 currencies are net return- shock transmitters.
