A framework for assessing and improving the resilience of complex engineered systems during the early design process

Creator:: Mehrpouyan, Hoda
Abstract:: As modern systems continue to increase in size and complexity, they pose significant safety and risk management challenges. System engineers and much of the government research efforts are focused on understanding the attributes and characteristics that emerge from the interactions of components and subsystems. As a result, the objective of...

A model of ciliary streaming in the respiratory system

Creator:: Chambers, Alan B.
Abstract:: The respiratory tract is lined with a mucous blanket which is motivated by a ciliated epithelium. This blanket includes a lower serous layer of fluid through which the cilia beat and an upper viscid layer into which particulates from the inhaled air are deposited. The movement of the mucous blanket...

A numerical analysis of ice fog produced by automobiles

Creator:: Nelson, William George
Abstract:: A model of an exhaust plume was developed and programmed on a digital computer. The purpose of the model was to predict the concentration and size distribution of ice particles produced from automobile exhaust during arctic conditions. The model accounted for the nucleation, growth, and freezing of the condensed water...

A risk-informed decision making framework accounting for early-phase conceptual design of complex systems

Creator:: Van Bossuyt, Douglas L.
Abstract:: A gap exists in the methods used in industry and available in academia that prevents customers and engineers from having a voice when considering engineering risk appetite in the dynamic shaping of early-phase conceptual design trade study outcomes. Current methods used in Collaborative Design Centers either collect risk information after...

A theory of product design process measurement

Creator:: Wright, Alan Louis
Abstract:: This dissertation approaches the problem of how to design process measurements by identifying process attributes which are common to all product development processes. By classifying the generic attributes of a product development process and their relationships, a framework is established which gives definition and context to individual measurements. At the...

An architecture for a function driven mechanical design solution library

Creator:: Wood, Stephen L.
Abstract:: The engineering design process and the advancement of future computer-aided-design systems need new design aids to be used during the conceptual design phase. This design phase is where information gathering and understanding of the problem are developed, analyzed and broken into small more manageable elements. These elements consist of customer...

An experimental study of the fluid mechanics of filling a small part of modular mold

Creator:: Miller, Mark Wade, 1967-
Abstract:: Investment casting has been an important form of metal casting for many years, but little is understood about the fluid flows that occur during mold filling. A key to quality castings is the understanding and control of the fluid flows that are present when the mold is filled with molten...

An investigation of the removal of ozone by activated charcoal

Creator:: Liffick, Glenn Lonngren
Abstract:: The removal of ozone from an air stream by activated-cocoanut charcoal was investigated from the literature and experimentally. The experimental investigation showed that activated-cocoanut charcoal can be used to remove concentrations of ozone less than 1.0 ppm with high efficiencies. The mechanism of the ozone removal appeared to be a...

Analysis of an externally loaded prestressed cylindrical shell

Creator:: Webb, Gerald Bruce
Abstract:: The concept of a prestressed cylindrical shell was investigated. In particular, a cylindrical shell constructed from coiled pressurized tubing was analyzed. This analysis was concentrated in two main areas, the first involved the failure modes of the prestressed cylinder. Both the buckling and yielding behavior of the tube walls was...
