periodontal ligament is a thin layer of soft tissue that connects root of a tooth to the surrounding alveolar bone. these ligaments play an important role in initiating tooth movement when loads are applied to teeth with orthodontic appliances. the majority of such soft tissues exhibit as viscoelastic bodies or have a time-dependent behavior. due to the viscoelastic behavior of the periodontal ...

In this paper, analysis of a system consists of two dependent components with load sharing is introduced. The life and repair times of the units are assumed to follow bivariate Weibull distribution. Markov models are used to construct the mathematical model of the system. Analysis of the availability function, reliability function, steady state availability, and mean time to system failure are ...

This paper presents a hybrid photovoltaic (PV)-diesel management system performance analysis considering weather conditions. The is designed to operate based on charging current, battery capacity, and loading current. During current decreased but the capacity high, PV remains supplied for low medium When lowered in middle, still supplies However, when decreases voltage below 22.3 volts, supply ...

the present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using markov birth-death process and probabilistic approach. in present paper, the feed water system consists of four subsystems. after drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...

While we know that in principle quantum mechanics is needed for a comLecture 3 9/29/09 continued from N4 pletely correct theory of the microscopic behavior of materials, it is also well understood that classical mechanics is a very good approximation for many purposes. In particular, as long as we are not concerned with very low temperatures or high frequency vibrations, then classical mechanic...

As grow as the data-intensive applications in cloud computing day after day, data popularity in this environment becomes critical and important. Hence to improve data availability and efficient accesses to popular data, replication algorithms are now widely used in distributed systems. However, most of them only replicate the static number of replicas on some requested chosen sites and it is ob...
