This paper analyzed the multi-machine repairable system with one unreliable server and repairman. The machines may break at any time. One oversees servicing machine breakdown. fail time different failure rates in idle busy repairman is responsible for repairing failure; repair rate variable to adapt whether are all functioning normally or not. All distributions exponential. Using quasi-birth-de...

TECHNOLOGY has rendered accounting obsolete. Recognition and acceptance of this fact are necessary if accountants are to make meaningful change, rather than fritter away their limited resources trying to repair the creaking, sagging, old machine. Presumably, if accountants had been assigned the job of landing man on the moon, we would still be earthbound while they continued to tinker with an o...

The present paper identifies the mistakes made by a data driven Bengali chunker. The analysis of a chunk based machine translation output shows that the major classes of errors are generated from the verb chunk identification mistakes. Therefore, based on the analysis of the types of mistakes in the Bengali verb chunk identification we propose some modules. These modules use tables of manually ...

The ability to monitor the condition of an electrical machine has been a concern of industry for many years. Knowing when a machine requires maintenance allows users to perform the required maintenance at their convenience, rather than during costly unscheduled shutdowns. This need for improved industrial monitoring techniques has produced a number of studies on the detection of mechanical faul...

In practice, machine schedules are usually subject to disruptions which have to be repaired by reactive scheduling decisions. The most popular predictive approach in project management and machine scheduling literature is to leave idle times (time buffers) in schedules in coping with disruptions, i.e. the resources will be under-utilized. Therefore, preparing initial schedules by considering po...

We study the reliability and sensitivity analysis of a system with M operating machines, S warm standbys, and a repairable service station. Failure times and service times of each machine (operating or standby) are assumed to be exponentially distributed. While the service station is working, it is subject to breakdowns according to a Poisson process. When the station breaks down, it requires ...

Activation-induced deaminase (AID) initiates antibody diversification in germinal center (GC) B cells through the deamination of cytosines on immunoglobulin genes. AID can also target other regions in the genome, triggering mutations or chromosome translocations, with major implications for oncogenic transformation. However, understanding the specificity of AID has proved extremely challenging....

The management of traumatic dislocation of the knee in 40 patients (41 knees) with a mean age of 26.3 years is described. They were treated by primary repair and reconstruction with autologous grafting of the anterior (ACL) and posterior cruciate ligaments (PCL) and repair injuries to the collateral ligament and soft-tissue. The ACL and PCL were reconstructed using the patellar tendon and the g...
