A comparison of the load rating method of bridge evaluation currently used in practice and the reliability-based evaluation method considered to be the method of choice in the future is presented. Evaluation methods may include techniques such as nondestructive evaluation, load testing, corrosion detection, and load rating. The most commonly used method of bridge evaluation in current state of practice is the load rating method mandated by the standards and manuals in this field. Performance assessment based on structural reliability has also been widely reported in the literature and in bridge code calibration as the state of the art bridge evaluation technique. The load rating and the reliability-based performance assessment techniques serve the same purpose (i.e., bridge evaluation) but have different theoretical bases and completely different formulations. Both rating and reliability can be used to measure either safety or serviceability of a bridge component or the bridge itself. In this paper, comparison of these two evaluation criteria is performed using the rating factor and the reliability index, based on the results of a comprehensive study focusing on reliability analysis of existing highway bridges.

Priority based multi-constrained quality of service routing in military applications
Araz, Bora; Koçyiğit, Altan; Department of Information Systems (2005)
This thesis proposes a new algorithm for multi-constrained Quality of Service Optimal Path Routing in the context of military applications. The objective of our routing algorithm is to manage network traffic according to quality of service requirements of connection requests using military metrics. The algorithm is mainly based on communication priority. The QoS metrics such as bandwidth, delay and packet loss ratio are considered as basic metrics on path finding. If there is no suitable path for the reques...
Assessment of web-based courses: a discussion and analysis of learners individual difference and teaching-learning process
Gülbahar, Yasemin; Yıldırım, İbrahim Soner; Department of Computer Education and Instructional Technology (2002)
This study examined the role of individual differences and the quality of the teaching-learning process on learning outcomes in a web-based instructional environment, and explored the implications of these variables on the design, delivery and evaluation stages of web-based instruction. The subjects of this study were the students of two web-supported traditional courses, being one undergraduate and the other graduate, offered by the Computer Education and Instructional Technologies Department of METU. Fort...
Moving Object Detction in 2D and 3D Scenes
Sırtkaya, Salim; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2004)
This thesis describes the theoretical bases, development and testing of an integrated moving object detection framework in 2D and 3D scenes. The detection problem is analyzed in stationary and non-stationary camera sequences and different algorithms are developed for each case. Two methods are proposed in stationary camera sequences: background extraction followed by differencing and thresholding, and motion detection using optical flow field calculated by أKanade-Lucas Feature Trackerؤ. For non-stationary ...
Forced Response Prediction of Constrained and Unconstrained Structures Coupled Through Frictional Contacts
Ciğeroğlu, Ender; Menq, Chia-Hsiang (ASME International, 2009-03-01)
In this paper, a forced response prediction method for the analysis of constrained and unconstrained structures coupled through frictional contacts is presented. This type of frictional contact problem arises in vibration damping of turbine blades, in which dampers and blades constitute the unconstrained and constrained structures, respectively. The model of the unconstrained/free structure includes six rigid body modes and several elastic modes, the number of which depends on the excitation frequency. In o...
Dynamic characteristics and performance assessment of reinforced concrete structural walls
Kazaz, İlker; Gülkan, Polat; Department of Civil Engineering (2010)
The analytical tools used in displacement based design and assessment procedures require accurate strain limits to define the performance levels. Additionally, recently proposed changes to modeling and acceptance criteria in seismic regulations for both flexure and shear dominated reinforced concrete structural walls proves that a comprehensive study is required for improved limit state definitions and their corresponding values. This is due to limitations in the experimental setups, such that most previous...
