Improvement of operation and availability of MSF plants
Desalination, 1996Abstract Ways to improve the safety, availability and efficiency of MSF plants by using improved control algorithms are described: state and adaptive proportional integral derivative (PID) controller or a self-setting function for conventional controllers.

Availability of generating units operated discontinuously
Proceedings of the Institution of Electrical Engineers, 1974Some of the important aspects for reliability assessment of power systems are outlined to quantify a desired security level. This quantification eliminates subjective guesswork, and enables efficient prediction of future operating conditions.This requires simple and computationally efficient models.

Operational Availability of Railway Dispatch Communication System
2009 Fourth International Conference on Dependability of Computer Systems, 2009In the article, issues on assessment of operational availability of transport telematic systems are presented. Digital railway dispatch communication system has been selected for analysis and assessment. Presented has been the model of the system’s exploitation process, including its functional structure. Markov and semi-Markov processes have been used

An optimal sparing model for the operational availability to approach the inherent availability
Annual Reliability and Maintainability Symposium. 2001 Proceedings. International Symposium on Product Quality and Integrity (Cat. No.01CH37179), 2002In an operating system, especially for the military, it is very desirable to achieve a high operational availability (A/sub O/). In fact, the optimal goal would be for the operational availability to approach or equal the inherent availability (A/sub I/).

Generic Management of Availability in Fail-Operational Automotive Systems
2017The availability of functionality is a crucial aspect of mission- and safety-critical systems. This is for instance demonstrated by the pursuit to automate road transportation. Here, the driver is not obligated to be part of the control loop, thereby requiring the underlying system to remain operational even after a critical component failure. Advances

Using a Smartphone as an Exoscope Where an Operating Microscope is not Available
World Neurosurgery, 2019Neurosurgical operating rooms are equipped with microscopes in order to provide a good standard of care. Nevertheless, in developing countries, microscopes are not always available. During a short period in a western Africa hospital, we adapted our smartphones as a valid alternative to the microscope.Using a shaped tin can, a smartphone cover, and a ...

Available Operations for Wisdom Teeth Preservation
2019For the normal positioned wisdom tooth, if it has the occlusal relationship with the teeth in the opposite jaw, or its crown is covered with gingival flap, or its adjacent teeth is losing and with retaining the wisdom teeth for restoration, it is better to retain the wisdom teeth.

Availability Modeling and Analysis for Data Backup and Restore Operations
2012 IEEE 31st Symposium on Reliable Distributed Systems, 2012Data backup operation is an essential part of common IT system administration to protect against data loss caused by any storage failures, human errors, or disasters. Lost data can be recovered from the backed up data if it exists. Since the backup and restore operations accrue downtime overhead or performance degradation, they have to be designed to ...
