Mechanistic Pavement Design Considering Bottom-Up and Top-Down-Cracking
2012Pavement design and pavement life-time estimation are generally realized by using mechanistic-empiric pavement design tools. In this paper an improved design procedure is presented that integrates bottom-up-fatigue-cracking and low-temperature-induced top-down-fatigue-cracking in a narrow time-scale. Considering a design period of decades (e. g.

Comparative analysis of top-down and bottom-up methodologies for multi-agent system design
Proceedings of the fourth international joint conference on Autonomous agents and multiagent systems, 2005Traditionally, top-down and bottom-up design approaches have competed with each other in Algorithmics and Software Engineering. In the top-down approach, 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.

An Approach Toward Integrating Top-Down and Bottom-Up Product Concept and Design Selection
Journal of Mechanical Design, 2011This paper proposes an approach to integrate top-down and bottom-up procedures for product concept and design selection. The top-down procedure identifies relationships between product requirements and design parameters and specifies an acceptable range of design parameters (called a design range) from product specifications and tolerances.

Developing a comprehensive and comparative questionnaire for measuring personality in chimpanzees using a simultaneous top‐down/bottom‐up design [PDF]
American Journal of Primatology, 2013 AbstractOne effective method for measuring personality in primates is to use personality trait ratings to distill the experience of people familiar with the individual animals. Previous rating instruments were created using either top‐down or bottom‐up approaches. Top‐down approaches, which essentially adapt instruments originally designed for use with

Teaching Top-Down ASIC/SoC Design vs Bottom-Up Custom VLSI
2007 IEEE International Conference on Microelectronic Systems Education (MSE'07), 2007In the fast paced world of IC design, companies strive for ways to create competitive, robust designs, while delivering speedy time-to-market results. A top-down design flow provides a fast, results oriented design methodology, but, at most Universities, the strong legacy of the Mead/Conway approach has lead to custom methods being the default way to ...

Cross-layer optimization for wireless networks: top-down or bottom-up design?
2009 International Conference on Communications, Circuits and Systems, 2009In 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 ...

Information and Software Technology, 2012
In resource-flow systems, e.g. production lines, agents are processing resources by applying capabilities to them in a given order. Such systems benefit from self-organization as they become easier to manage and more robust against failures. In this paper, we demonstrate the conception of a decentralized coordination process for resource-flow systems ...

Top-Down Bottom-Up Design Methodology for Fast and Reliable Serdes Developments in nm Technologies
2008This paper describes the development of high speed serial data communication links from the viewpoint of signal and circuit complexity. It proposes a development method to deal in qreliable and affordable with the increasing complexity. Two example implementations are discussed: a 10 Gbps link in 0.13 μm CMOS and a 2.5 Gbps PCI-Express link in 90 nm ...
