A new wideband Wilkinson Power Divider which use the nonuniform substrate integrated waveguide (NSIW) method is presented in this paper. This structure utilizes NSIWs instead of the uniform quarter wavelength SIWs in conventional Wilkinson power divider. The proposed structure is analyzed by odd and even mode analysis. The proper NSIW section widths can be extracted by using even mode while the...
In the current study, a thermal model was used to investigate the effects of welding parameters on the distribution of temperature in wide gap aluminothermic rail welds. To solve the governing thermal equation, SUTCAST, a finite difference program (FDM) was employed while different aspects such as phase change and convective heat transfer in weld pool were taken into account in the numerical so...
This study compares the energy intensity performance in Indonesia to other south-east Asia countries such as Vietnam, Thailand, Singapore, The Philippines and Malaysia for the period from 1971 to 2016. For this goal, this research employs a multiplicative Log Mean Divisia Index II method and Spatial-Temporal Index Decomposition Analysis. The manufacturing sector and commercial sector played a k...
myocardial infarction (mi) and its major determinant, coronary artery disease (cad), are complex diseases arising from the interaction between several genetic and environmental factors. until recently, the genetic basis of these diseases was poorly understood. genome-wide genetic association studies have afforded a comprehensive insight into the association between genetic variants and diseases...
in the natural disasters such as earthquake, based on severity of trauma, time under the rubble and quality/quantity of hydratation we will confront with a spectrum of traumatic rhabdomyolysis. in present study we evaluate victims of bam earthquake to show different stage of muscle trauma, from minor trauma with almost normal level of muscle enzyme to those with moderate trauma leading to crush...
background: evidence shows that in iran alcohol abuse rate may be of concern, especially among the youth. the mental and social health and addiction department of the ministry of health and medical education has designed a plan to prevent, treat, and rehabilitate the patients abusing alcohol in a time period of 2011‑2015. methods: in a 6‑month period, three guiding committees of experts in the ...
LPWANs are a class of technologies that have very low power consumption and high range of communication. Along with its various advantages, these technologies also have many limitations, such as low bandwidth, connectionless transmission and low processing power, which has challenged encryption methods in this technologies. One of the most important of these challenges is encryption. The very s...
