Summary
A supervised learning scheme is proposed for detecting, locating, and quantifying the intensity of damage in structures using Artificial Neural Networks (ANNs) and Proper Orthogonal Decomposition (POD). For structural systems, such as buildings and bridges, Proper Orthogonal Modes (POMs) associated with their response are functions of (1) applied external loads and (2) mechanistic properties. In the present research, a supervised learning strategy was adopted to help discriminate POM variations because of damage from damage caused by applied load variations. A neural classifier was trained to categorize response to different load patterns, and a regression ANN was subsequently trained using an ensemble of applied loads to detect possible damage from the categorized POMs. To demonstrate the effectiveness of the proposed approach, simulated experiments were performed with the intent of identifying damage indices for a railway truss bridge. A validated, three‐dimensional (3D) finite element (FE) model of an existing bridge was used to generate strain time histories under train loads measured from weigh‐in‐motion (WIM) stations near the bridge. The efficacy of the proposed method was demonstrated through these simulated experiments.
Corporate Identity Management (CIM) in universities has been acknowledged in marketing literature as an important area of research. Research within the current spectrum of CIM indicates some ambiguities surrounding corporate identity in higher education. However, very few studies are available in the field of corporate identity within universities. Accordingly, the objective of this study is to examine the relationships between university's CIM and organizational performance, and also identify the relevant underlying mechanisms in Malaysian highereducation sector. Based on a review of the existing literature in a range of areas, this study proposes a conceptual model of the positive relationships between CIM activities in universities with internal brand, transformational leadership and organisational culture. The proposed conceptual model is developed based on three main theories--social identification theory, transformational leadership theory and social learning theory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
