Unavailability Calculations within the Limits of Computer Accuracy

چکیده
The paper presents a new analytical algorithm which is able to carry out direct and exact reliability quantification of highly reliable systems with maintenance (both preventive and corrective). A directed acyclic graph is used as a system representation. The algorithm is based on a special new procedure which permits only summarization between two or more nonnegative numbers that can be very different. If the summarization of very small positive numbers transformed into the machine code is performed effectively no error is committed at the operation. Reliability quantification is demonstrated on a real system from practice.

Accuracy Evaluation of Isogray TPS Dose Calculations in Symmetric and Asymmetric Fields of the Elekta Compact Linear Accelerator
Introduction: Radiation therapy is one of the most important methods of cancer treatment. Radiation therapy uses symmetric and asymmetric fields in which the radiation dose distribution is different. To calculate the dose distribution, computer treatment planning systems are used which must have acceptable calculations accuracy. The aim of this study was to investigate the accuracy of the dose ...

The aim of this experiment was to study the effect of computer game on acquisition and retention of free throw basketball skills (accuracy and pattern) and compare this method with two patterning methods (skilled and learning). 50 high school students age range 15-17 years were selected as a research samples. Subjects after participating in the pretest were divided into 5 equal groups and each ...
متن کاملA Computer Modeling of Mie-Scattering by Spherical Droplets Within the Atmosphere
The Earth’s atmosphere is an environment replete with particles of differ-ent sizes with various refractive indices which affect the light radiation traveling through it. The Mie scattering theory is one of the well-known light scattering techniques ap-plicable to modeling of electromagnetic scattering from tiny atmospheric particles or aerosols floating in the air or within the clouds. In this...
متن کاملA New Optimized Hybrid Model Based On COCOMO to Increase the Accuracy of Software Cost Estimation
The literature review shows software development projects often neither meet time deadlines, nor run within the allocated budgets. One common reason can be the inaccurate cost estimation process, although several approaches have been proposed in this field. Recent research studies suggest that in order to increase the accuracy of this process, estimation models have to be revised. The Construct...
متن کاملCentralized Clustering Method To Increase Accuracy In Ontology Matching Systems
Ontology is the main infrastructure of the Semantic Web which provides facilities for integration, searching and sharing of information on the web. Development of ontologies as the basis of semantic web and their heterogeneities have led to the existence of ontology matching. By emerging large-scale ontologies in real domain, the ontology matching systems faced with some problem like memory con...
