As tri-gate transistor technologies continue to scale to smaller dimensions, a variety of aging mechanisms become important to include in models to accurately predict end-of-life transistor performance. Traditional aging effects such as BTI and hot carrier continue to play a role. However, modeling these mechanisms becomes more complicated with the addition of recovery, variation, and local self-heating...
This paper proposes a methodology to assess cyber-related risks and to identify critical assets both at power grid and substation levels. The methodology is based on a two-pass engine model. The first pass engine is developed to identify the most critical substation(s) in a power grid. A mixture of Analytical hierarchy process (AHP) and (N-1) contingent analysis is used to calculate risks. The second...
Cyclic loading induces fatigue in bone and initiates a complex, functionally adaptive response. We investigated the effect of a single period of fatigue on the histologic structure and biomechanical properties of bone. The ulnae of 40 rats were subjected to cyclic fatigue (-6000 με) unilaterally until 40% loss of stiffness developed, followed by 14 days of adaptation. The contralateral ulna served...
Computer models have been playing important roles in modern design, particularly at the component and subsystem levels. As competition increases, the challenge of design has shifted from individual components to overall systems. Alternative paradigms, different models and new approaches for using these models are needed to support system designs. This paper presents a “Model Fusion” approach to enable...
