Abstract: fabricated. Modifications carried out in different parts of the old system in order to control mostof the growth parameters with more accuracy. The fabricated system was used to grow sapphiresingle crystals with almost 10 mm in diameter and 50 mm in length. The crystallinity andstructure of the grown crystals were characterized by computer aided single crystal X-raydiffraction techniq...

The ISA is the established hardware-software contract. As the ISA hides hardware features that affect timing of execution, it is no longer sufficient for ensuring system security and safety. We argue that a new contract is required, which exposes such features.

There is ongoing interest in utilising user experiences associated with security and privacy to better inform system design and development. However, there are few studies demonstrating how, together, security and usability design techniques can help in the design of secure systems; such studies provide practical examples and lessons learned that practitioners and researchers can use to inform ...

often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. instead it is obtained by some numerical analysis such as fe structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...
