Planning framework is commonly used to represent intelligent agents effectively and to model complex behavior. In planning framework, resource-based perspective is interesting in the sense that in a multi-agent environment, exchange of resources can form a cooperative interaction. In resource based plan coordination, each agent constructs an individual plan, then plans are examined by a central plan revision unit for possibilities of removing actions. Domain of this work is the classical postmen domain that is also modifed to have non-sub-additive property.The domain is has numerous challenges that is not considered in the original plan coordination model. Moreover, the plan coordination algorithm is used in the re-planning phase, as the environment changes through plan execution.These issues are common for the realistic environments and the details of the original plan coordination perspective are renewed to cope with these issues.

Face detection in active robot vision
Önder, Murat; Halıcı, Uğur; Department of Electrical and Electronics Engineering (2004)
The main task in this thesis is to design a robot vision system with face detection and tracking capability. Hence there are two main works in the thesis: Firstly, the detection of the face on an image that is taken from the camera on the robot must be achieved. Hence this is a serious real time image processing task and time constraints are very important because of this reason. A processing rate of 1 frame/second is tried to be achieved and hence a fast face detection algorithm had to be used. The Eigenfa...
Scheduling approaches for parameter sweep applications in a heterogeneous distributed environment
Karaduman, Gülşah; Şener, Cevat; Alpdemir, Mahmut Nedim; Department of Computer Engineering (2010)
In this thesis, the focus is on the development of scheduling algorithms for Sim-PETEK which is a framework for parallel and distributed execution of simulations. Since it is especially designed for running parameter sweep applications in a heterogeneous distributed computational environment, multi-round and adaptive scheduling approaches are followed. Five different scheduling algorithms are designed and evaluated for scheduling purposes of Sim-PETEK. Development of these algorithms are arranged in a way t...
Implementation of concurrent constraint transaction logic and its user interface
Altunyuva, Fethi; Karagöz, Pınar; Department of Computer Engineering (2006)
This thesis implements a logical formalism framework called Concurrent Constraint Transaction Logic (abbr.,CCTR) which was defined for modeling and scheduling of workflows under resource allocation and cost constraints and develops an extensible and flexible graphical user interface for the framework. CCTR extends Concurrent Transaction Logic and integrates with Constraint Logic Programming to find the correct scheduling of tasks that involves resource and cost constraints. The developed system, which integ...
Software process improvement based on static process evaluation
Seçkin, Haldun; Bilgen, Semih; Department of Electrical and Electronics Engineering (2006)
This study investigates software development process improvement approaches. In particular, the static process evaluation methodology proposed by S. Güceğlioğlu is applied on the requirements analysis and validation process applied in Project X in MYCOMPANY and an improved process is proposed. That methodology is an extension of the ISO/IEC 9126 approach for software quality assessment, and is based on evaluating a set of well-defined metrics on the static model of software development processes. The improv...
Bayesian learning under nonnormality
Yılmaz, Yıldız Elif; Alpaslan, Ferda Nur; Department of Computer Engineering (2004)
Naive Bayes classifier and maximum likelihood hypotheses in Bayesian learning are considered when the errors have non-normal distribution. For location and scale parameters, efficient and robust estimators that are obtained by using the modified maximum likelihood estimation (MML) technique are used. In naive Bayes classifier, the error distributions from class to class and from feature to feature are assumed to be non-identical and Generalized Secant Hyperbolic (GSH) and Generalized Logistic (GL) distribut...
