چکیده
A gray scale providing easy visual interpretation of black-and-white photoscan transparencies was determined empirically from psychophysical studies conducted on 50 observers. This optimum gray scale provides equal visualization for equal countrate changes over the entire film range.

Multi-objective Optimization of Stirling Heat Engine Using Gray Wolf Optimization Algorithm (TECHNICAL NOTE)
The use of meta-heuristic optimization methods have become quite generic in the past two decades. This paper provides a theoretical investigation to find optimum design parameters of the Stirling heat engines using a recently presented nature-inspired method namely the gray wolf optimization (GWO). This algorithm is utilized for the maximization of the output power/thermal efficiency as well as...

متن کاملEvaluation of gray scale changes of CBCT system images in different axis using the DICOM file
The images of dental CBCT imaging systems used in conic shaped beams, stored in the DICOM format, have various applications in the dentistry, including bone density estimation to select the location of the orthodontic implant, bone loss detection and etc. In these systems, unlike CT imaging systems, the resulting images exhibit gray-scale non-uniformity in each of the different axis in FOV. Thi...
متن کاملFast Cellular Automata Implementation on Graphic Processor Unit (GPU) for Salt and Pepper Noise Removal
Noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. A common problem in imaging systems by using CMOS or CCD sensors is appearance of the salt and pepper noise. This paper presents Cellular Automata (CA) framework for noise removal of distorted image by the salt an...
متن کاملPharmacological properties of some 3-substituted indole derivatives, a concise overview
Indole is a nitrogen-containing heterocycle. It is a very important motif in agriculture and pharmacy. Many compounds containing indole moiety has been isolated form nature. It is also an important part in natural alkaloids. Tryptophan is an amino acid which posses indole. 3-Sustituted indoles are the main group of its derivatives. Because the wide-spread application of 3-substituted indolic co...
