Evaluation of performance and optimum valve settings for pressure management using forecasted daily demand curves by artificial neural networks
Yıldız, Evren; Merzi, Nuri; Department of Civil Engineering (2011)
For the appropriate operation and correct short term planning, daily demand curve (DDC) of municipal water distribution networks should be forecasted beforehand. For that purpose, artificial neural networks (ANN) is used as a new method. The proposed approach employs already recorded DDCs extracted from the database of ASKI (Ankara Water Authority) SCADA center and related independent parameters such as temperature and relative humidity obtained from DMI (State Meteorological Institute). In this study, a co...
Evaluation of aggregate size effect on asphalt mixture homogeneity using image analysis
Yücel, Ayhan Öner; Güler, Murat (null; 2018-10-12)
The purpose of this study is to evaluate effect of aggregate size fractions on asphalt mixture inhomogeneity by means of a proposed inhomogeneity test method. The study of inhomogeneity is conducted using 2-dimensional, vertical section images of asphalt concrete specimens that are produced using the Superpave gyratory compactor. Mixture inhomogeneity is evaluated based on aggregates distribution because aggregates are the primary constituent governing the inhomogeneity level of asphalt mixtures during the ...
Evaluation of Image Representations for Player Detection in Field Sports Using Convolutional Neural Networks
Sah, Melike; Direkoglu, Cem (2018-08-28)
Player detection is an important task in sport video analysis. Once players are detected accurately, it can be used for player tracking, player activity/performance analysis as well as team activity recognition. Recently, convolutional Neural Networks (CNN) became the state-of-the-art in computer vision for object recognition. CNN based methods usually use gray or RGB images as an input. It is also possible to use other image representation techniques such as shape information image and polar transformed sh...
Evaluation of Warm Mix Asphalt compactability indices using laboratory compactors from a temperature perspective
Pamuk, Omer Can; Öztürk, Hande Işık (2021-04-01)
In practice, the production temperatures of Warm Mix Asphalt (WMA) mixtures are determined based on practical experiences and recommendations. Thus, the focus of this study is to propose a temperature-sensitive compactabilty assessment method to quantify the temperature needs of WMA mixtures. Therefore, in this study, an image-based testing setup coupled with the Marshall Apparatus was developed to obtain the densification curve of asphalt mixtures considering its sensitivity to temperature changes. Further...
Evaluation of Acoustic Gunshot Localization Methods on Helicopters with Environmental Sound Simulations
Yılmaz, Murat; Günel Kılıç, Banu (Springer, London/Berlin , 2022-07-01)
Although there are ground based localization solutions for Small Arms Fire (SAF) attacks, there are only a few implementations of onboard applications. A simple Acoustic Source Localization (ASL) application employs a microphone array for collecting audio signals, so as to locate sound sources using the measurements from the sound field. The aim of this study is to investigate the possibility of Acoustic Gunshot Localization on a helicopter so as to detect and localize SAF attacks, by simulating the effects...
