Abstract:

This current study empirically tested elements of Ehlers and Clark's (2000) cognitive model of Posttraumatic Stress Disorder (PTSD) symptom maintenance using path analysis and structural equation modeling (SEM). Ehlers and Clark's model suggests that a reciprocal relationship between cognitive appraisals of the traumatic event and characteristics of the trauma memory maintain symptoms by increasing one's sense of current threat. Participants in the current study were 405 undergraduates at a Midwestern university who each reported having experienced at least one traumatic event during his/her

Abstract:

Structural equation models combine factor analysis models and multivariate regression models to estimate associations between observed variables and unobserved variables. The main achievement of this Capstone Project is the understanding of structural equation models and application of the models to real-world data. In this report, we reviewed structural equation models and several prerequisite topics. We performed a simulation study to compare maximum likelihood structural equation model estimation versus two-stage sequential estimation using multiple linear regression and maximum likelihood

Abstract:

Recent empirical assessments revealed that footprint indicators calculated with various multi-regional input-output (MRIO) databases deliver deviating results. In this paper, we propose a new method, called structural production layer decomposition (SPLD), which complements existing structural decomposition approaches. SPLD enables differentiating between effects stemming from specific parts in the technology matrix, e.g. trade blocks vs. domestic blocks, while still allowing to link the various effects to the total region footprint.

Abstract:

A recent paper explored a potential deficiency in the single frequency harmonic response structural dynamic analysis approach typically used to assess a resonant condition in turbomachinery flow path components. This deficiency is prevalent in supersonic flow conditions when non-adjacent stages are present. The previous investigation demonstrated other excitation sources present in complex or supersonic flows could be missed using the typical analysis approach, in some cases leading to large under-prediction of structural response when compared with a baseline transient analysis.

Politics' demand for informative consumption-based emission assessments based on multi-regional input output (MRIO) databases is steadily increasing. Based on the MRIO database EXIOBASE 3, we exemplify the utility of a range of analytical tools and discus their potential insights for consumption-based policies. The analysis decomposes the overall EU carbon footprint into product groups as well as into emitting regions. Subsequently, we illustrate the potential of applying production layer decomposition (PLD) and structural path analysis (SPA) for the assessment of global supply-chains relat

Pollution studies have sought to understand the relationships between adverse health effects and harmful exposures. Many environmental health studies are predicated on the idea that each exposure has both acute and long term health effects that need to be accurately mapped.

There are many statistical issues that arise in the exploration of these longitudinal study designs such as understanding pathways of effects, add

Abstract:

Structures of machinery with practical importance, such as home appliances or transportation vehicles, can be considered as acoustically coupled spaces surrounded by elastic enclosures. When the structures of machinery are excited mechanically by means of prime movers incorporated into these structures through some elastic connections, generation of noise becomes an inevitable by-product. For noise control engineering purposes, a thorough understanding of emission, transmission and radiation of sound from structure is required prior to a possible and practical modeling of noise transfer mechan

One of the remarkable features of Brahm's B-flat major Intermezzo for piano, Op. 76, no. 4 is the ambiguity of its tonal definition. The work disclosed a contrapuntal tension between its fundamental structural-harmonic organization, which is based on an incomplete harmonic progression (V7-I), and its more remote intermediary tonal areas, which Brahms implies throughout the Intermezzo but to which he never wholly commits.<br>The aim of this investigation is to illustrate how tonal ambiguity is achieved though recurrent "incompletions" of the expected (or at least the more likely) harmonic progr

Abstract:

Phonon transport analysis in nano- and micro-porous materials is critical to their energy-related applications. Assuming diffusive phonon scattering by pore edges, the lattice thermal conductivity can be predicted by modifying the bulk phonon mean free paths with the characteristic length of the nanoporous structure, i.e., the phonon mean free path (Lambda(pore)) for the pore-edge scattering of phonons. In previous studies (Jean et al., 2014), a Monte Carlo (MC) technique have been employed to extract geometry determined Lambda(pore) for nanoporous bulk materials with selected periods and poro

Abstract:

Complex products are comprised of a large number of tightly integrated components, assemblies and systems resulting in extensive logical and physical interdependences between the constituent parts. Thus a change to one item of a system is highly likely to lead to a change to another item, which in turn can propagate further. The aim of this research therefore is to investigate dependency models that can be used to identify the impact and trace thepropagation of changes in different information domains, such as requirements, physical product architecture or organisation.

Abstract:

Cieľom tejto práce je návrh analýzy tvaru haldy vhodnej pre potreby analyzátora 2LS. 2LS je nástroj pre analýzu C programov založený na automatickom odvodzovaní invariantov s použitím SMT solvera. Navrhované riešenie obsahuje spôsob reprezentácie tvaru programovej haldy pomocou logických formulí nad teóriou bitových vektorov. Tie sú následne využité v SMT solveri pre predikátovú logiku prvého rádu na odvodenie invariantov cyklov a súhrnov jednotlivých funkcií analyzovaného programu. Náš prístup je založený na ukazateľových prístupových cestách, ktoré vyjadrujú dosiahnuteľnosť objektov na halde

Abstract:

La comparación de imágenes es un ingrediente fundamental en muchos problemas de procesamiento de imagen y visión por computador. Esta tesis aborda el problema de la comparación de entornos locales en imágenes, o patches, por medio de medidas de similitud (o funciones distancia). En particular, estudiamos el problema de la comparación invariante afín de imágenes a partir de sus patches, lo cual abre la puerta a un análisis más profundo de la estructura de similitud y auto-similitud existente en imágenes naturales. Nuestro trabajo parte de una aproximación axiomática reciente a las medidas de si

Abstract:

The presence of a hole in the vicinity of a growing fatigue crack may lead to deviation of the crack path. If the hole is too near the crack path, the crack may terminate at the edge of the hole, leading to crack arrest. In this project, a finite element based two dimensional crack propagation simulator software FRANC2D and a pre-processor software for this simulator CASCA developed by Cornell Fracture Group of Cornell University was used for prediction of crack propagation in a beam containing a hole. Four point bending test experiment was carried out on an aluminum beam and crack

Abstract:

Load transfer analysis deals with an important function of engineering structure, which is the ability of structure in transferring imposed loads to the supporting points. Although stress value has proved to be an efficient index for performing the failure analysis, the necessity of defining an index for evaluation of structure stiffness has led to the introduction of the U* index theory. The U* index characterizes the internal stiffness distributions, as an indicator of the load transfer in the structure. Although U* index theory have been proven to be useful in design, it is missing necessar

Abstract:

Over the past two decades there has been an upsurge in interest in structural equation modelling (SEM). Applications abound in the social sciences and econometrics, but the use of this multivariate technique is not so common in public health research. This dissertation discusses the methodology, the criticisms and practical problems of SEM. We examine actual applications of SEM in public health research. Comparisons are made between multiple regression and SEM and between factor analysis and SEM. A complex model investigating the utilization of antenatal care services (ANC) by migrant w

Abstract:

The study was conducted in order to test the application of the social accounting matrix-based structural path analysis to urban agriculture at the local level. This was part of an attempt to advance an alternative methodology that could guarantee higher levels of precision and reliability in the measurement and analysis of the role of urban agriculture. A quantitative field survey research design characterised by stratified random sampling of respondents and consultation of secondary SAM data based on South Africa already in the public domain were used.
