The correspondence problem is an important problem when the subjects have two different kinematical structures imitating each other. In this new approach, the imitator and the imitate have totally different dynamics systems, the first one is the fluidic system, the second one is the human hand gestures. The motion of the fluidic system is composed of the combination of fluid particles which are used for the discretization of the problem domain. Observed human hand gestures are imitated by these fluid particles by appropriately adjusting the parameters of the Smoothed Particle Hydrodynamics (SPH), which is a particle based Lagrangian method. In this paper we analyzed the dynamics of the SPH, and used an artificial neural networks (ANN) based controller which automatically adjust the SPH parameters, specifically the body force, to create the desired hand preshapes.

Imitation of basic hand preshapes by fluid based method: fluidics formation control Tilki, Umut; Erkmen, İsmet; Erkmen, Aydan Müşerref (2011-01-01) In this paper, a new approach is developed, avoiding the correspondence problem caused by the difference in embodiment between imitator and demonstrator in imitation learning. In our work, the imitator is a fluidic system of dynamics totally different than the imitatee, which is a human performing hand gestures. The fluidic system is composed of fluid particles, which are used for the discretization of the problem domain. In this work, we demonstrate the fluidics formation control so as to imitate by observ...
Imitation of Basic Hand Preshapes by Fluid Based Method: Fluidic Formation Control Erkmen, Aydan Müşerref; Erkmen, İsmet (2009-11-05) In this paper, a new approach is developed handling the correspondence problem due to the difference in embodiment between imitator and demonstrator in imitation learning. In our work the imitator is a fluidic system of dynamics totally different than the demonstrator which is human hand gestures. In this work we demonstrate the fluidic formation control so as to generate basic hand preshaping features. Our fluidic formation control is based on Smoothed Particle Hydrodynamics (SPH), which is a particle base...
Modeling of asymmetric intermodulation distortion and memory effects of power amplifiers Yüzer, Ahmet Hayrettin; Demir, Şimşek; Department of Electrical and Electronics Engineering (2011) This dissertation is focused on developing a new passband behavioral model in order to account for asymmetric intermodulation distortion resulted from memory effect. First, a measurement setup is prepared to measure the AM/AM, AM/PM distortion, magnitudes and the phases of intermodulation (IMD) and fundamental (FUND) components which are created by the amplifier where phase is calculated only by measuring magnitudes. Then, responses of a sample amplifier are measured for different excitation situations (cen...
Weighted shapes for embedding perceived wholes Keles, Hacer Yalim; Özkar Kabakçıoğlu, Mine; Tarı, Zehra Sibel (2012-01-01) Embedding parts is a key problem in computing when dealing with continuous matter such as shapes rather than discrete matter such as symbols. For computing part relations such as embedding, a technical framework that uses weighted shapes is introduced and implemented. In the proposed framework, for any given two-dimensional shape, the entire canvas is defined as a weighted shape and serves as a registration mark in detecting embedded parts. The approach treats shapes as perceived wholes rather than composed...
Relationship between styles of humor and divergent thinking Cayirdag, Nur; Acar, Selcuk (2010-02-08) The aim of the present study was to investigate the relationship between styles of humor and divergent thinking of Turkish 6(th), 7(th), and 8(th) grade students. Styles of humor were measured by Humor Style Questionnaire and divergent thinking was measured by Guilford's Uses Test. Two measurements were administered to 84 6(th), 7(th) and 8(th) grade students. Using bivariate correlations among 4 styles of humor, fluency, originality, and creativity, it was found that aggressive humor style was negatively c...
