In an article published in the journal Nanomaterials, researchers presented a cost-efficient optimized cylindrical optical antenna with a wide field of view (FOV) and quick response time due to high-efficient nanomaterials.
In a study published in Applied System Innovation, researchers implemented a barn door tracker and stacking technique with CMOS DSLR or mirrorless cameras to collect data and capture images of low light-emitting sources such as the faint nebulae and the human body.
In an article published in the open-access journal Sensors, researchers introduced a new-generation approach employing a one-class classification framework for assessing the authenticity of facial photos. Such a generation technique was developed to create a compatible and feasible structure with new data and other datasets rather than relying heavily on the dataset used for training.
