Local energy losses at positive and negative steps in subcritical open channel flows
Tokyay, Nuray; Altan Sakarya, Ayşe Burcu (2011-01-01)
Local energy losses occur when there is a transition in open channel flow. Even though local losses in subcritical open channel flow due to changes in channel width have been studied, to date no studies have been reported for losses due to changes in bed elevations. Steps are commonly used in engineering applications to stabilise the flow in open channels. Hence, it is important to estimate local losses for design purposes. The aim of this study was to formulate the local energy losses at positive and negat...
Local Anomaly Detection in Crowded Scenes Using Finite-Time Lyapunov Exponent Based Clustering
Öngün, Cihan; Temizel, Alptekin; Taşkaya Temizel, Tuğba (2014-08-29)
Surveillance of crowded public spaces and detection of anomalies from the video is important for public safety and security. While anomaly detection is possible by detection and tracking of individuals in low-density areas, such methods are not reliable in high-density crowded scenes. In this work we propose a holistic unsupervised approach to cluster different behaviors in high density crowds and detect the local anomalies using these clusters. Finite-Time Lyapunov Exponents (FTLE) is used for analyzing th...

Local chemical and topological order in Al-Tb and its role in controlling nanocrystal formation
Kalay, Yunus Eren; HWANG, Jinwoo; VOYLES, P. M.; KRAMER, M. J. (2012-02-01)
How the chemical and topological short- to medium-range order develops in Al-Tb glass and its ultimate effect on the control of the high number density of face-centered-cubic-Al (fcc-Al) nuclei during devitrification are described. A combined study using high-energy X-ray diffraction (HEXRD), atom probe tomography (APT), transmission electron microscopy and fluctuation electron microscopy (FEM) was conducted in order to resolve the local structure in amorphous Al90Tb10. Reverse Monte Carlo simulations and V...
