The objective of the paper is to propose a privacy model for ubiquitous healthcare system involving unconventional information sources like laboratory scanning equipments, networked computing systems and distributed wireless sensors using an actor based domain specific approach. In the existing privacy models for ubiquitous healthcare systems the trust on the middleware and the deployed security mechanisms...
A statistical algorithm was developed for the damage fault diagnosis and prognosis tool and the present work focuses on the experimental validation. The oxide scale growth experiments using laboratory samples under thermal cycling simulate the hot section turbine blade coating failures. The experimental steps, oxide thickness data measurement, collection and sampling procedures are discussed. Three...
Maintenance of life safety and engine efficiency coupled with reduced life cycle cost, form the major motivations for the upgradation and development of structural health assessment and management technology (SHAMT). However, there are several major challenges to realizing the full benefits of the technology by many industries, still remain. These include, damage awareness tools and techniques, data...
Algorithmic approaches for failure risk assessment, anomaly detection and life prognosis of gas turbine blade are discussed. Modeling of blade tip clearance and Monte Carlo simulation considering creep, vibration and other damaging effects lead to two probabilistic distributions with blade tip clearance data. Failure risk can be determined during blade life usage based on blade tip tolerance limits...
