Pyridoacridine ascididemin analogues have been reported as anticancer agents for their interesting antitumor activity against human cancer cells. A quantitative structure-activity relationship (QSAR) analysis of ascididemin analogues was attempted using the physicochemical parameters and the electrotopological state atom (ETSA) indices. This study indicates(More)
Subcutaneous mycoses caused by the family Entomophthoraceae is very rare type of disease and is being reported sporadically from various Tropical countries including India. Here we report 8 cases of rhinoentomophthoromycosis caused by Conidiobolous coronatus and 7 cases of chronic subcutaneous phycomycosis caused by Basidiobolus ranarum. Cases were detected(More)
Inter-symbol interference (ISI) due to multipath fading is a vital problem in high-speed wireless communication which restricts communication quality and capacity. Therefore, in addition to choosing a fading mitigation technique, it is also important to strategically select a modulation scheme for effective data transmission. Recent literature review on(More)
The scope of this paper is interference cancellation which is concerned with removal of noise superposed on speech signal. Interference cancelling makes use of an auxiliary or reference input derived from one or more sensor located in noise field where the signal is undetectable. This input is filtered from primary input containing both signal and(More)
A method for representation of floating-point numbers with the help of integers is proposed. Simple mathematical operations involving the former are also defined in the new representation. High level codes developed for fixed-point targets may contain floating point expressions and simple modifications in the code according to the proposed conversions can(More)
Process plants deal with hazardous (highly flammable and toxic) chemicals at extreme conditions of temperature and pressure. Proper inspection and maintenance of these facilities is paramount for the maintenance of safe and continuous operation. This article proposes a risk-based methodology for integrity and inspection modeling (RBIIM) to ensure safe and(More)
