The benefits and limitations of using both deterministic and probabilistic analysis are demonstrated using two case studies. The incorporation of High Consequence Area (HCA) data with deterministic and probabilistic analysis is an effective way to track the corrosion risk of a pipeline through time. Both types of analysis of high-resolution in line inspection corrosion data can be used to plan excavation and repair programs and set safe re-assessment intervals. Back to back high resolution corrosion inspections are presented to validate the use of these techniques along with a discussion on how to properly allocate resources to manage corrosion uncertainty.

Abstract This paper presents an effective device-level failure analysis (FA) method which uses a high-resolution low-kV Scanning Electron Microscope (SEM) in combination with an integrated state-of-the-art nanomanipulator to locate and characterize single defects in failing CMOS devices. The presented case studies utilize several FA-techniques in combination with SEM-based nanoprobing for nanometer node technologies and demonstrate how these methods are used to investigate the root cause of IC device failures. The methodology represents a highly-efficient physical failure analysis flow for 28nm and larger technology nodes.

A new embodied digital rhetoric emerges when using nonfiction narratives built in fully immersive virtual reality systems that take advantage of the plasticity of our sensations of presence. The feeling of “being-in-the-world” as described by phenomenologists, including philosophy of mind, film, and virtual reality theorists, is part of the adaptability that humans show in their relationship to technological tools. Andy Clark's “soft selves” and our “plastic presence” merge as the high resolution graphics of the latest virtual reality goggles and robust audio captured at real events tricks our minds into having an embodied connection with the stories portrayed in these new spaces. By putting people into news or documentary pieces on scene as themselves, opportunities for persuasive and effective rhetoric arise. This chapter cites theory, psychology and virtual reality research as well as the author's specific case studies to detail the potential for this new embodied digital rhetoric that allows us to pass through the screen and become present as witnesses to a nonfiction story.

The decommissioning of nuclear facilities indicates that the site is finally released according to a limited or unlimited site reuse purpose. In this process, the assessment of exposure dose to decommissioning workers and nearby residents is essential. Based on MARSSIM, a widely used decommissioning guideline in the United States, derivation of the exposure dose and derived concentration guideline level (DCGL) is mandatory using the probabilistic analysis of the RESRAD code. Here, DCGL is the radionuclide-specific concentration that satisfies the site release criteria. By applying the priority 1 parameter, which has the greatest effect on the dose, the dose is derived through deterministic and probabilistic analyses. The results were compared and analyzed. The purpose of this study was to provide a basic database that can be applied to the development of parameter lists and distributions suitable for the characteristics of nuclear facilities in South Korea. In addition, the process of deriving the dose by applying the deterministic and probabilistic analyses of RESRAD was assessed.

Upper-flow-regime bedforms and their role in the evolution of marine and lacustrine deltas are not well understood. Wave-like undulations on delta foresets are by far the most commonly reported bedforms on deltas and it will take time before many of these features get identified as upper-flow-regime bedforms. This study aims at: (1) Providing a summary of our knowledge to date on deltaic bedforms emplaced by sediment gravity flows; (2) illustrating that these features are most likely transitional upper-flow-regime bedforms; and (3) using field case studies of two markedly different deltas in order to examine their role in the evolution of deltas. The study combines numerical analysis with digital elevation models, outcrop, borehole, and high-resolution seismic data. The Mazzarrà river delta in the Gulf of Patti, Italy, is selected to show that upper-flow-regime bedforms in gullies can be linked to the onset, growth, and evolution of marine deltas via processes of gully initiation, filling, and maintenance. Ice-marginal lacustrine deltas in Germany are selected as they illustrate the importance of unconfined upper-flow-regime bedforms in the onset and evolution of distinct delta morphologies under different lake-level trends.
