No full textThis thesis addresses the problem of Multi-Agent Path Finding problem where multiple agents aim to reach their destination in a grid world without any colli sion. It aims to provide a solution achieving good trade-off between the privacy of the agents and the effectiveness of solutions. Accordingly, a token-based bilateral negotiation approach is presented to solve this problem in a distributed way. The proposed approach is evaluated empirically in various scenarios by comparing it with state-of-the-art centralized approaches such as Conflict Based Search and its variants. The experimental results showed that the proposed approach can find conflict-free path solutions albeit suboptimally, especially when the search space is large and high-density, whereas centralized approaches struggle to find optimal solutions. Despite being outperformed by suboptimal centralized solvers, the pro posed decentralized approach can achieve considerable results with naive agents by sharing minimal information about themselves. The proposed approach also enables agents to have their autonomy; thus, the proposed approach is convenient for MAPF problems involving self-interested agents.Bu tez, coklu etmenli sistemlerde yol planlamas problemine, muzakere yontemi tabanl bir yakla s m geli stirmeyi hede iyor.

Decentralized multi-agent path finding framework and strategies based on automated negotiation
No full textThis paper introduces a negotiation framework to solve the Multi-Agent Path Finding (MAPF) Problem for self-interested agents in a decentralized fashion. The framework aims to achieve a good trade-off between the privacy of the agents and the effectiveness of solutions. Accordingly, a token-based bilateral negotiation protocol and two negotiation strategies are presented. The experimental results over four different settings of the MAPF problem show that the proposed approach could find conflict-free path solutions albeit suboptimally, especially when the search space is large and high-density. In contrast, Explicit Estimation Conflict-Based Search (EECBS) struggles to find optimal solutions. Besides, deploying a sophisticated negotiation strategy that utilizes information about local density for generating alternative paths can yield remarkably better solution performance in this negotiation framework.Interactive Intelligenc
A Decentralized Token-Based Negotiation Approach for Multi-Agent Path Finding
No full textThis paper introduces a negotiation approach to solve the Multi-Agent Path Finding problem. The approach aims to achieve a good trade-off between the privacy of the agents and the effectiveness of solutions. Accordingly, a token-based bilateral negotiation protocol and a compatible negotiation strategy are presented. The proposed approach is evaluated in a variety of scenarios by comparing it with state-of-the-art centralized approaches such as Conflict Based Search and its variant. The experimental results showed that the proposed approach can find conflict-free path solutions with a higher success rate, especially when the search space is large and high-density compared to centralized approaches while the gap between path cost differences is reasonably low. The proposed approach enables agents to have their autonomy; thus, it is convenient for MAPF problems involving self-interested agents

Estimation of Exterior Parameters of Sensor Combination for Efficient 3D Modeling
No full textISPRS-Commission V Mid-Term Symposium on Close Range Image Measurement Technique -- JUN 21-24, 2010 -- Newcastle upon Tyne, ENGLANDLaser scanning is the latest method to collect 3D spatial data and modelling. It becomes more and more popular in engineering applications such as 3D modeling, deformation analysis, reverse engineering and urban planning. However, laser scanners are not sufficient on their own for 3D surveying and modeling. It should be used together with the photogrammetric data especially in the orientation of point clouds, measurement of the non-scanning areas, and texture mapping. This task needs the combination of range sensor and image sensor. The sensor combination like this is a very efficient and flexible system for close-range measurement applications. Most of the laser scanners include integrated camera but most of them are low resolution and they can not be removed independent from the scanner. Therefore high resolution camera should be mounted to the laser scanner. In this study we consider mounting a camera onto laser scanner and estimating exterior parameters with strong control methods. We also made experimental studies by using exterior parameters.ISPRS CommissScientific and Technological Research Council of Turkey ( TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK); "Foreign Research Scholarship Program" to Cihan ALTUNTAS; Vienna University of Technology; Scientific Research Found of The Selcuk University ( BAP)We would like to thank The Scientific and Technological Research Council of Turkey ( TUBITAK) for the financial support they have provided as a part of "Foreign Research Scholarship Program" to Cihan ALTUNTAS to the carried out this study in Vienna University of Technology.

Phase transitions, elastic and electronic properties of hydrogen storage Na2PdH4
No full textHydrogen can be absorbed by some materials at specific pressures and temperatures. This is extremely important in terms of creating carbon-free and sustainable society. In this work hydrides are good candidates to fulfill these aims. Electronic and magnetic properties of hydrides are investigated. This study considers Na2PdH4 as solid storage of hydrogen material. Hydrogen is highly soluble in palladium and can be stored in large amounts at ambient conditions. The structural evolution, electronic and elastic properties of Na2PdH4 has been investigated by means of density functional theory. The SIESTA software package is used with the generalized gradient approximation for the exchange-correlation functional and norm-conserving Troullier-Martins pseudopotentials. High-pressure computations have been carried out to reveal phase transitions. Na2PdH4 is transformed from I4/mmm tetragonal structure to Immm orthorhombic structure at 100 GPa. The electronic band structures and density of states are obtained for both phases. Mechanical stability is analyzed using the elastic constants. Moreover, several parameters such as Young's modulus, shear modulus, and their ratios are obtained and discussed. © 2021 Author(s)
A Pedagogical Stylistic Study of “Eleven” by Sandra Cisneros
No full textKnowing about the linguistic and stylistic features of any literary texts in general and the aspect of lexical pattern in particular, concerning the way through which the author uses adjectives, verbs, nouns and adverbs provide us with precious information that can be helpful in judging about the appropriateness of the text to be used for a specific purpose such as teaching to EFL students in a specific level. Therefore, according to the importance of this issue, and based on the checklist of linguistic and stylistic categories proposed by Leech and Short (2000), the stylistic analysis of the short story entitled “Eleven” written by Sandra Cisneros was performed in this study from the lexical category dimension. In the end, the results and findings of the study are elaborated and discussed, with the conclusion that the author was successful in using the appropriate diction and linguistic features to express her main points from the tongue of an Eleven-year-old kid who is also ten, nine, eight, seven, six, five, four, two and one year old.
