Focal Frame Loss: A Simple but Effective Loss for Precipitation Nowcasting

Nowcasting of Precipitation

Focal Loss Dense Detector for Vehicle Surveillance

Deep learning has been widely recognized as a promising approach in different computer vision applications. Specifically, one-stage object detector and two-stage object detector are regarded as the most important two groups of Convolutional Neural Network based object detection methods. One-stage object detector could usually outperform two-stage object detector in speed; However, it normally t...

Convolutional LSTM Network: A Machine Learning Approach for Precipitation Nowcasting

The goal of precipitation nowcasting is to predict the future rainfall intensity in a local region over a relatively short period of time. Very few previous studies have examined this crucial and challenging weather forecasting problem from the machine learning perspective. In this paper, we formulate precipitation nowcasting as a spatiotemporal sequence forecasting problem in which both the in...

A Simple Precipitation Method for Synthesis CoFe2O4 Nanoparticles

Magnetic CoFe2O4 nanoparticles were synthesized via a simple chemical reaction using precipitation method. The obtained materials consist of ferrite particles with average diameter of 25 nm. The effect of different surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. Scanning electron microscopy was used to study the structure and particle size o...

Risk factors for hearing loss in infants: a systematic review

Background and Objective: Hearing loss as a sensory disorder is among the most common developmental disorders. Based on the universal neonatal screening results, the incidence of hearing deficit is 1–3 per 1000 live births in the well-baby nursery population and 2–4 in 100 newborns in the intensive care community. The aim of this study was to highlight the main risk factors for hearing loss bas...
