We analyze an example of the application of polymer tribology to create a safety medical device, namely a retractable syringe. In service at various stages either lowor high-dynamic friction is needed. Our work focuses on a VanishPoint® nonreusable safety syringe manufactured by Retractable Technologies, Inc., Little Elm, TX. Different medical-grade materials strongly affect the performance of ...

the principle of “non-retractable agreement between contractual and non-contractual responsibility” is a traditional rule in the french law and countries adapting the french law of harmony and homogeneity; this rule means that if the claim for petition is based on the mistake, i.e., if it was meant to be based on contractual liability, rather than liability enforced in accordance with establish...

Time-dependent reliability-based design optimization (RBDO) has been acknowledged as an advance optimization methodology since it accounts for time-varying stochastic nature of systems. This paper proposes a time-dependent RBDOmethod considering both of the time-dependent kinematic reliability and the time-dependent structural reliability as constrains. Polynomial chaos combined with the moving...

In recent years, multiple geospatial ontologies have been developed for a wide range of different spatial databases. In addition, the development of volunteered geographic information both challenges and provides opportunities to the traditional authenticated geospatial information. Though volunteered geographic information is typically not as reliable and structured as the authenticated geospa...
