The implementation of concurrent engineering into many large
companies has greatly improved their product development processes.
These companies have seen significant gains in quality and customer
satisfaction with reduced product costs, defects, and time-to-market
(Lake, 1992). Many large companies have successfully employed this
relatively new product development philosophy. However, smaller...
Phase-space trajectories are often used to describe a system's
stability or response characteristics. It is desirable to observe such
a phase-space trajectory directly from an analog simulation of a
system, but a conventional oscilloscope display does not provide an
axis for the third variable,
A third axis could be provided...
Monte Carlo simulation is used to quantify and characterize uncertainty in a variety of applications such as financial/engineering economic analysis, and project management. The dependence or correlation between the random variables modeled can also be simulated to add more accuracy to simulations. However, there exists a difference between how correlation...
The International Handbook of Evaluated Reactor Physics Benchmark Experiments contains detailed descriptions of many different reactor facilities. A large portion of these experiments have not been fully modeled due to the unavailability of computational power at the time of the experiment’s execution. With the advent of renewed interest in Sodium...
Tolerance analysis is a major link between design and
manufacturing. An assembly or a part should be designed
based on its functions, manufacturing processes, desired
product quality, and manufacturing cost. Assembly tolerance
analysis performed at the design stage can reduce potential
manufacturing and assembly problems. Several commonly used
assembly tolerance...
Continues improvement of industrial systems require constant measuring process variation and eliminating extraneous variation whenever possible to push the target measures as close to the ideal value as possible. Statistical Processes Control (SPC) technique is a very efficient statistical technique for monitoring and controlling processes variation. In recent years an...
An analysis method for moving loads computes the internal demand history in a structural member at integration points of force-based finite elements as opposed to the end forces of a refined displacement-based finite element mesh. The force-based formulation satisfies strong equilibrium of internal section forces with the element end forces...
