This thesis discusses applying AI planning tools for generating plans for manual operations. Expertise of motion economy domain is used to select good plans among feasible ones. Motion economy is a field of industrial engineering, which deals with observing, reporting and improving manual operations. Motion economy knowledge is organized in principles regarding the sequences and characteristics of motions, arrangement of workspace, design of tools etc. A representation scheme is developed for products, workspace and hand motions of manual operations. Operation plans are generated using a forward chaining planner (TLPLAN). Planner and representation of domain have extensions compared to a standard forward chaining planner, for supporting concurrency, actions with resources and actions with durations. We formulated principles of motion economy as search control temporal formulas. In addition to motion economy rules, we developed rules for simulating common sense of humans and goal-related rules for preventing absurd sequences of actions in the plans. Search control rules constrain the problem and reduce search complexity. Plans are evaluated during search. Paths, which are not in conformity with the principles of motion economy, are pruned with motion economy rules. Sample problems are represented and solved. Diversity of types of these problems shows the generality of representation scheme. In experimental runs, effects of motion economy principles on the generation of plans are observed and analyzed.

New montgomery modular multıplier architecture Çiftçibaşı, Mehmet Emre; Yücel, Melek D; Department of Electrical and Electronics Engineering (2005) This thesis is the real time implementation of the new, unified field, dualا radix Montgomery modular multiplier architecture presented by Savaş et al, for performance comparison with standard Montgomery multiplication algorithms. The unified field architecture operates in both GF(p) and GF(2n). The dual radix capability enables processing of two bits of the multiplier in every clock cycle in GF(2n) mode, while one bit of the multiplier is processed in GF(p) mode. The new architecture is implemented in a Xi...
Moving object identification and event recognition in video surveillance systems Örten, Burkay Birant; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2005) This thesis is devoted to the problems of defining and developing the basic building blocks of an automated surveillance system. As its initial step, a background-modeling algorithm is described for segmenting moving objects from the background, which is capable of adapting to dynamic scene conditions, as well as determining shadows of the moving objects. After obtaining binary silhouettes for targets, object association between consecutive frames is achieved by a hypothesis-based tracking method. Both of t...
Genetic algorithm for personnel assignment problem with multiple objectives Arslanoğlu, Yılmaz; Toroslu, İsmail Hakkı; Department of Computer Engineering (2006) This thesis introduces a multi-objective variation of the personnel assignment problem, by including additional hierarchical and team constraints, which put restrictions on possible matchings of the bipartite graph. Besides maximization of summation of weights that are assigned to the edges of the graph, these additional constraints are also treated as objectives which are subject to minimization. In this work, different genetic algorithm approaches to multi-objective optimization are considered to solve th...
A simulation tool for mc6811 Sarıkan (Tuncer), Nazlı; Güran, Hasan; Department of Electrical and Electronics Engineering (2004) The aim of this thesis study is to develop a simulator for an 8-bit microcontroller and the written document of this thesis study analyses the process of devoloping a software for simulating an 8 bit microcontroller, MC68HC11. In this simulator study a file processing including the parsing of the assembler code and the compilation of the parsed instructions is studied. Also all the instruction execution process containing the cycle and instruction execution and the interrupt routine execution is observed th...
A mathematical contribution of statistical learning and continuous optimization using infinite and semi-infinite programming to computational statistics Özöğür-Akyüz, Süreyya; Weber, Gerhard Wilhelm; Department of Scientific Computing (2009) A subfield of artificial intelligence, machine learning (ML), is concerned with the development of algorithms that allow computers to “learn”. ML is the process of training a system with large number of examples, extracting rules and finding patterns in order to make predictions on new data points (examples). The most common machine learning schemes are supervised, semi-supervised, unsupervised and reinforcement learning. These schemes apply to natural language processing, search engines, medical diagnosis,...
