A lens forms an upright and diminished image of an object placed at its focal point. Name the lens and draw a ray diagram to show the formation of an image.Solution:In a concave lens, the lens forms an upright and diminished image of an object placed at its focal point....
2.1.1 Object and Image All lens design procedures are based on the principles of geometrical optics, which assumes that light travels along rays that are straight in a homogeneous medium. Light rays are refracted or reflected at a lens or mirror, where they proceed to form an image. Due to...
Ageing in the lens and cataract formation The transmission of light decreases with age, especially for the lower wavelengths (up to a factor of 10), to the point that at low levels of illumination an apparent tritanopia can occur (see Ch. 5, p. 302). Morphologically, the cells lose cyto...
The image which is being formed through the concave lens is upright, smaller in size than the object and is virtual. The position of the image which is being formed is between the lens and the objects and is regardless of the position of the object. Whereas the image which is being forme...
(image + time series) multi-class ("no lens," "lensed galaxy," "lensed type-Ia supernova," "lensed core-collapse supernova") classification architecture shows relatively low accuracy on the most challenging simulated datasets. Moreover, the simulated data set, as presented in [8], contains...
All the parameters were initialized with the ImageNet weights40. We trained the models for 50 epochs with a batch size of 32 and chose the model with optimal performance on the tuning set for each mode of image. Interpretable visualization of DL models A gradient-weighted class activation map...

For example, as a zoom lens which is compact and is excellent in image formation performance, there conventionally exists a three group zoom lens consisting of a negative first lens group, a positive second lens group and a positive third lens group in order from the object side as described...

This case study shows how an 8-year-old boy with autism and mild intellectual disability underwent positive psychological development in terms of play, social communication, and mentalization during a year and a half of group-based therapy using COMSI
