Blending Top-Down and Bottom-Up Approaches in Conceptual Design
In recent years, there has been significant attention given to improved methods and tools for engineering design. While advances for the latter stages of design have been impressive, this has not been the case for the early stages of design. In general, advances have provided for either a top-down or a bottom-up approach to design; ignoring the requirements for both abstraction and detail in a ...
متن کاملTop-Down versus Bottom-Up Approaches in Risk Management
Banks and other financial institutions face the necessity to merge the economic capital for credit risk, market risk, operational risk and other risk types to one overall economic capital number to assess their capital adequacy in relation to their risk profile. Beside just adding the economic capital numbers or assuming multivariate normality, the top-down and the bottom-up approach have been ...
متن کاملTop-down and bottom-up approaches towards silicon nanoelectronics
The performance of silicon-based VLSI circuits has steadily been improved by scaling down device dimensions, and a nearly exponential growth of microelectronics capabilities has been achieved. However, maintaining this top-down miniaturization trend is getting exceedingly hard due to fundamental physical and technological limitations as well as of the economical limitation. Nonconventional bott...
متن کاملCombining Top-down and Bottom-up approaches for ROBDD Construction
ROBDDs have traditionally been built in a bottom-up fashion, through the recursive use of Bryant's apply procedure [6], or the ITE [4] procedure. With these methods, the peak memory utilization is often larger than the nal ROBDD size. Though methods like Dynamic Variable Reordering [21] have been proposed to reduce the memory utilization, such schemes have an associated time penalty. In this pa...
متن کاملPortfolio Credit Risk : Top down Vs . Bottom up Approaches
Dynamic reduced form models of portfolio credit risk can be distinguished by the way in which the intensity of the default process is specified. In a bottom up model, the portfolio intensity is an aggregate of the constituent intensities. In a top down model, the portfolio intensity is specified without reference to the constituents. This expository article contrasts these modeling approaches. ...
