Human beings suffer from several infectious agents such as viruses, bacteria, and protozoans. Recently, there has been a great interest in developing biocompatible nanostructures to deal with infectious agents. This study investigated benign ZnCuO nanostructures that were visible-light-responsive due to the resident copper in the lattice. The nanostructures(More)
An approach to automatic character recognition based on human perception has been 1-3 reported elsewhere. In this approach, letters are described in terms of an abstract set of functional attributes, each of which can be related to a type of ambiguity between two letters. The relations between the physical attributes derived from the physical image and the(More)
During this period, our efforts have concentrated on three major problems associated with the audio response system that we are designing. First, two all-digital vocal-tract model systems have been designed, each using different serial arithmetic techniques , and each requiring less than 100 TTL MSI circuits. These designs are being implemented, and after(More)
Most present-day picture coding is digital; virtually all input and output images are analog. Thus the conversion from one form to the other is everpresent and important to the quality and efficiency of the overall process. To elucidate the phenomena involved, a systematic study was carried out on a wide variety of pre-sampling and interpolation filters. It(More)
Lipid and protein oxidation are well-known manifestations of free radical activity and oxidative stress. The current study investigated extermination of Leishmania tropica promastigotes induced by lipid and protein oxidation with reactive oxygen species produced by PEGylated metal-based nanoparticles. The synthesized photodynamic therapy-based doped and(More)
Our current emphasis on text-to-speech conversion for unrestricted text and for audio announcement systems centers on improvements to the quality of phonemic synthesis and on the development of prosodic algorithms for the control of pitch and timing. In the area of phonemic synthesis, an improved algorithm is being implemented that not only provides for(More)
