This paper deals with an (n + 1)-unit warm standby system based on imperfect repair facility and two types of failures. These types of failure are hardware and human error failures. Various measures of the system reliability are obtained using the regenerative point technique. Finally a numerical example is presented to illustrate the theoretical results.(More)
Two simple, accurate, and precise chromatographic methods have been developed and validated for the determination of dronedarone (DRO) HCl and amiodarone (AMI) HCl either alone or in binary mixtures due to the possibility of using AMI as a counterfeit of DRO because of its lower price. First, an RP-HPLC method is described for the simultaneous determination(More)
A simple, accurate, and precise LC method with a reversed stationary phase was developed and validated for the determination of perindopril (PER) arginine, amlodipine (AML), and indapamide (IND) alone and in binary mixtures (PER arginine is found in two dosage forms, i.e., with either AML or IND). Chromatographic separation was carried out on a BDS(More)
