  • Speech and hearing are closely linked human abilities. It could be said that human speech is optimised toward the frequency ranges that we hear best, or perhaps our hearing is optimised around the frequencies used for speaking. However whichever way we present the argument, it should be clear to an engineer working with speech transmission and processing systems that aspects of both speech and hearing must often be considered together in the field of vocal communications. However, both hearing and speech remain complex subjects in their own right. Hearing particularly so....

  • H ere is a simple way to adjust exposure in the f-stop increments that is second nature to photographers. The key to this technique is that the Screen and Multiply layer blending modes, at an opacity of 38%, produce an effect very similar to lightening or darkening by one full f-stop. (For half-stop adjustments, use 19% opacity, for one-third stop use 13%, and so on.) In this example, we’ll darken the image by one stop.

There are several accounts of published research in insect pathology in the early literature dating from Bassi's incrimination of Beauveria bassiana as a pathogen of the silkworm in 1835, but the field came into its own in the 1940s and 1950s with the development of formal course work in insect pathology and the publication of Principles of Insect Pathology (Steinhaus, 1949).
