A Post-mortem Analysis of Production Process: The Bricklayer's Disaster
… The findings are presented in the spirit of a post-mortem analysis, which acts to collect the knowledge obtained by those involved with a project in order to increase productivity for the next time a similar task is attempted. The postmortem approach was found to be effective in identifying, …

The Effect of Local Conditions on Deformation Processes in Low Stacking -Fault Energy FCC Alloys
… quasi-static and high strain rate compression. Post-mortem analysis of the deformed microstructures at different levels of applied strain reveals the nucleation of deformation twins is affected by the grain size distribution of the bulk material. In these materials, deformation twins are …

Reduced graphene oxide nanoparticle hybrids and their assembly for lithium-ion battery anodes
… a fast decrease in capacity was observed. Post-mortem analysis of the electrodes showed that rGO becomes irreversibly passivated suggesting that additional measures to retain effective charge transport between the low weight percent conductive additive and the active phase during cycling …

Automating runtime optimizations for parallel object-oriented programming
… techniques have been embodied in the Paradise post-mortem analysis tool which automates several run-time optimizations without programmer intervention. Paradise builds a program representation from traces, analyzes characteristics, chooses and parameterizes optimizations, and generates hints to …

Uncovering the link between twin-twin interactions and damage nucleation in an (α+β) Ti alloy
… yet been investigated in detail. In this work, post-mortem analysis and an in-situ SEM-EBSD tensile experiment were conducted to determine where damage was nucleating most frequently in the microstructure, and what deformation modes were associated with damage nucleation. Damage within primary α …

Time-resolved and three-dimensional study of dislocation-particle interactions in aluminum and copper alloys
… inside the transmission electron microscope, post mortem analysis, and electron tomographic reconstructions. Specifically, diffraction-contrast electron tomography was developed during the course of this work as a 3D imaging technique for crystalline systems such that the dislocation and …

Subcooled flow boiling heat transfer and critical heat flux in water-based nanofluids at low pressure
… uncertainty of the CHF was less than 6.2%. A post-mortem analysis of the boiling surface reveals that its morphology is altered by deposition of the particles during nanofluids boiling. A confocal-microscopy-based examination of the test section revealed nanoparticles deposition not only …

Degradation mechanisms in La₀.₈Sr₀.₂CoO₃ as oxygen electrode bond layer in solid oxide electrolytic cells (SOECs)
… For SOECs provided by Ceramatec Inc. for this analysis, La₀.₈Sr₀.₂CoO₃ (LSC) was the bond layer and A₀.₈Sr₀.₂MnO₃ (ASM*) was the oxygen electrode, both comprised of perovskite structure. The approach in thesis integrated complementary spectroscopy and microscopy techniques in a novel manner to …

Wide Area Power System Monitoring Device Design and Data Analysis
… FDRs are time stamped to allow for comparative analysis between FDRs. The data is transmitted over the internet to a central server where the data is collected and stored for post mortem analysis. Currently, most of the analysis is done with power system frequency. The purpose of this study is …

The Advancement of Adaptive Relaying in Power Systems Protection
… but are not limited to, the logging of data for post-mortem analysis, communication throughout the system, as well changing relay parameters. Several concepts will be discussed, one of which will be implemented to prove the value of the new tools available.

A Single-Frequency Impedance Diagnostic for State of Health Determination in Li-ion 4P1S Battery Packs
… reduction in life compared to operating solo. Analysis of the fSoH data for these cells revealed a change in imaginary impedance at the critical frequency that corresponded to changes in the capacity and current data, supporting the development of a single-frequency diagnostic tool. An …

The response of concave singly curved fibre reinforced moulded sandwich and laminated composite panels to blast loading
… to 25 g, were detonated. After blast testing, a post-mortem analysis of the damaged panels was conducted. Post-mortem analysis revealed that the failure progression was the same irrespective of curvature for both the sandwich panels and the laminates. Sandwich panels exhibited the following …

A Glial Role in the Action of Electroconvulsive Therapy
… known to be implicated in emotional behavior. Post-mortem analysis of brain tissue from depressed patients, have suggested that neuronal and glial pathology, seen both as changes in cellular densities and glial cell loss, may underlie the depression-associated volumetric changes. The …

Mechanochemistry of metal-organic frameworks under compression
… of a two-wave feature in the shock profile. In post-mortem analysis on impacted ZIF-8, it has been discovered that the MOF crystals experience significant deformation with chemical decomposition near the impact surface, suggesting the energy absorption mechanism in MOFs via sacrificial …

Investigation of chemotherapy-induced peripheral neuropathy-related behaviour in male and female ratsa role for the endocannabinoid system
… impact of PTX on nociceptive behaviour. Post-mortem analysis of endocannabinoids and related Nacylethanolamines showed that PTX increased 2-arachidonoylglycerol, Npalmitoylethanolamide (PEA) and N-oleoylethanolamide levels in the amygdala of both male and female animals. Next, we assessed …
