On-line, continuous monitoring technologies of a rigorous and objective nature are sought to quantitatively identify and evaluate the condition or health of highway structures over their useful lifetime. A global bridge evaluation methodology is under development based upon the structural identification concept, employing modal testing, truckload testing, and instrumented monitoring as its principal experimental tools. Test results are transformed to either modal flexibility or the unit influence line, which have been demonstrated to be conceptual, quantitative, comprehensive, and damage-sensitive signatures. Four test sites were tested, monitored, and studied in order to classify their similar bridge-type-specific behavior mechanisms and to validate the performance of the implemented methodology. Practical, type-specific procedures for instrumented monitoring and nondestructive evaluation can then be developed for the whole group or type of highway bridges.

Automatic Mapping of Linearwoody Vegetation Features in Agricultural Landscapes AKSOY, SELİM; AKÇAY, HÜSEYİN GÖKHAN; Cinbiş, Ramazan Gökberk; Wassenaar, Tom (2008-07-11) Development of automatic methods for agricultural mapping and monitoring using remotely sensed imagery has been an important research problem. We describe algorithms that exploit the spectral, textural and object shape information using hierarchical feature extraction and decision making steps for automatic mapping of linear strips of woody vegetation in very high-resolution imagery. First, combinations of multispectral values and multi-scale Gabor and entropy texture features are used for training pixel le...
TIMELY COMMUNICATION FOR ENERGY-EFFICIENCY, DATA FRESHNESS AND TRACKING Bacınoğlu, Baran Tan; Uysal, Elif; Department of Electrical and Electronics Engineering (2021-9-1) This thesis considers data transmission scenarios where timeliness of information transmission, or adapting to intermittently available resources is important. The ﬁrst part of the thesis focuses on energy harvesting communication systems. For such systems, energy eﬃcient scheduling algorithms that achieve certain throughput maximization and data freshness objectives are developed. The second part of the thesis considers data transmission for the purpose of tracking unstable sources through noisy channels. ...
Time variant component and system reliability analysis of bridges Ghasemnejad Berenji, Vahid; Akgül, Ferhat; Department of Engineering Sciences (2015) This study aims to develop a time variant reliability algorithm for a bridge component or system capable of incorporating multiple deterioration and live load models to be selected by the user. The algorithm is developed as a shell program built over a previously developed core program (RELSYS) which is based on the First Order Reliability Method (FORM). After reviewing previous research performed on both time invariant and time variant bridge reliability, the fundamental concepts of time variant reliabilit...
Parallel Hybrid Genetic Algorithm and GIS-Based Optimization for Municipal Solid Waste Collection Routing Düzgün, H. Şebnem; Uşkay, S. Onur; Aksoy, Ayşegül (American Society of Civil Engineers (ASCE), 2016-01-01) A vast majority of studies on municipal solid waste (MSW) collection routing do not consider the constraints pertinent to actual road networks such as unidirectional roads and terrain characteristics. As a result, good practices such as the avoidance of U-turns cannot be used. This study introduces geographic information system (GIS)-integrated software (RouteSW) for the optimization of MSW collection routes by considering path constraints. The software uses a parallelized hybrid genetic algorithm (PHGA) to...
Imagery intelligence technology foresight and modeling of mobile applications in the defense industry Bilge, Başak; Çakır, Serhat; Department of Science and Technology Policy Studies (2018) Identifying the threats and impacts of an operation field requires continuous planning and emphasizes the importance of intelligence. With the development of electronic systems that support the military decision-making process increases in number, today long- time and high- risk discovery and surveillance operations are performed faster and safer. Therefore, developing technology policies to augment defense- technology research is a crucial step. Reorganization movements, management measures and operational...
