Top-Down Versus Bottom-Up Nanoengineering Routes to Design Advanced Oropharmacological Products

open access: closedCurrent Pharmaceutical Design, 2016
Energy intensive and chemical routes predominately govern modern dental material fabrication involving complex physicochemical approaches. Current interest in dental material design is shifting towards biomineralization method and green chemistry synthesis to support oral tissue biocompatibility and oropharmacology.

Top-down vs bottom-up methodologies in multi-agent system design

open access: closedAutonomous Robots, 2008
Traditionally, two alternative design approaches have been available to engineers: top-down and bottom-up. In the top-down approach, the design process starts with specifying the global system state and assuming that each component has global knowledge of the system, as in a centralized approach.

Cross-layer optimization for wireless networks: top-down or bottom-up design?

open access: closed2009 International Conference on Communications, Circuits and Systems, 2009
In this talk, we discuss the cross-layer optimization issues in wireless networks by investigating the impact of physical (PHY) layers on the media access control (MAC) and higher protocol layers, or vice versa. In particular, we explore the benefits of cross-layer design for multi-user multi-input multi-output (MU-MIMO) cellular mobile networks ...
