Investigating and understanding the impact of dust storms on wetland vegetation changes can lead to useful information for their optimal management.In this study, the wind rose and hurricane rose diagrams of the research area were prepared using wind statistics of Ahvaz meteorological stations.Changes in vegetation cover of Shadegan wetland were de
The aim of this study is to investigate stress wave propagation in metal Dialators foams under high-speed impact loading.Three-dimensional Voronoi model is established to represent real closed-cell foam.Based on the one-dimensional stress wave theory and Voronoi model, a numerical model is developed to calculate the velocity of elastic wave and sho
ABSTRACT: The novel variant IBDV (nVarIBDV, genotype A2dB1), characterized by bursal atrophy of fabricius and decreased lymphocytes, has been emerging on a large scale in Asia (including China) since late 2018.nVarIBDV is a new threat to the poultry industry, yet the currently licensed commercial vaccines, including the live viral vector vaccine, I
Orthogonal Frequency Division Multiplexing (OFDM) is the modulation technology used in Fourth Generation (4G) and Fifth Generation (5G) wireless communication systems, and it will likely be essential to Sixth Generation (6G) wireless communication systems.However, OFDM introduces a high Peak to Average Power Ratio (PAPR) in the time domain due to c
In this paper a novel modelling and solving method has been developed to address the so-called resource constrained project scheduling problem (RCPSP) where project tasks have multiple modes and also the 75 Ohm RG59 preemption of activities are allowed.To solve this NP-hard problem, a new general optimization via simulation (OvS) approach has been
