Development of complex systems is a collaborative effort spanning disciplines, teams, processes, software tools, and modeling formalisms. Increasing system complexity, reduction in available resources, globalized and competitive supply chains, and volatile market forces necessitate that a unified model-based systems engineering environment replace ad-hoc,(More)
Thermally induced warpage of printed wiring boards (PWB) and printed wiring assemblies (PWAs) is an increasingly important issue in managing the manufacturing yield and reliability of electronic devices. In this paper, we introduce complementary simulation and experimental verification procedures capable of investigating warpage at the local feature level(More)
In this paper we present Maestro, a model-based systems engineering (MBSE) environment for design and simulation of complex electronic systems using Orchestra—a simulation tool developed at Sandia National Laboratories. Maestro is deployed as a plugin for MagicDraw and uses Orchestra domain-specific language (DSL) which is based on SysML. Maestro enables a(More)
A novel method based on the shadow moiré and phase shifting techniques has been developed to measure the flatness of an object moving at a constant speed. In this method, we propose an angled grating approach to achieve phase shifting with a simple and low-cost system. A grating plane is positioned at a small angle with respect to the axis of motion of the(More)
