This dissertation aims to develop new condition-based maintenance (CBM) tools for increasing performance of Apache helicopter drivetrain gearboxes, through lubrication and signal analysis. An extensive consumer of CBM is the Apache helicopter that involves testing critical components to demonstrate reliability and performance, measured through data-driven condition indicators (CIs). These indic...
Gelatin, chitosan and hyaluronic acid are natural components used to prepare polymeric scaffold in tissue engineering. The physical properties of these materials confer an appropriate microenvironment for cells, which can be used as a regeneration system for skin and cartilage. In this work, we prepared and characterized a Gelatin/Chitosan/Hyaluronan lyophilized-polymer. Physical properties of ...
Experimental study of effective thermal conductivity of ZnO/EG nanofluid is presented in thisresearch. The nanofluid was prepared by dispersing Zno nanoparticles in ethylene glycol using asonicator and adding surfactant. Ethylene glycol based nanofluid containing ZnO nanoparticlewith a nominal diameter of 18 nm at different solid volume fractions (very low to high) atvarious temperatures was ex...
Reliable simulation of hot stamping process requires accurate material data. This paper describes the development of computer models that can provide many of the material data required, including TTT/CCT phase transformation diagrams, temperature dependent physical and thermophysical properties, as well as temperature and strain rate dependent mechanical properties including high temperature st...
