Deep convolutional neural networks (CNNs) have yielded unusually brilliant results in synthetic aperture radar (SAR) target recognition.However, overparameterization is a widely-recognized property of deep CNNs, and most previous works excessively pursued high accuracy but neglected the requirement of model deployment in radar systems, i.e., small … Read More


Owing to the increasing energy demand, producing more oil from the residual in the old reservoir by water flooding and enhanced oil recovery (EOR) methods should be considered.Water flooding has become the most widely used process by injecting water into the reservoir to displace oil.The chemical EOR is a chemical injection into the reservoir.When … Read More


Major challenges for automatic ship detection in optical remote sensing (ORS) images include cloud, wave, island, wake clutters, and even the high variability of targets.This paper presents a practical ship detection scheme to resolve these existing issues.The scheme contains two main coarse-to-fine stages: prescreening and discrimination.In the pr… Read More


The specimens of the tribe Syrphini, deposited at the Hayk Mirzayans Insect Museum, were examined and 30 species identified, of which one genus and three species are newly recorded from Iran and marked by an asterisk (*).Keys to the genera and species, Cosmetic Bag as well as their distribution in Iran, are provided.The species are as follows:Dasys… Read More
