Master Thesis Lower Body Dynamics for Rotational and Translational Activities: Cycling and Stair Climbing(01. Izmir Institute of Technology, 2023) Karacaoğlu, Bilal; Mihçin, ŞenayEvaluation of human movement performance in activities of daily living is an important component in clinical and rehabilitation settings. Motion capture technology is an effective method for objective evaluation of human motion. Here, movement kinematics and kinetic data are obtained from healthy individuals. In this thesis, it is detailed the daily life movements based on stair climbing and cycling. The aim of this study is to examine the effects of human movement on the kinetic and kinematic variables of the hip joint during stair climbing and descending. Data were collected using the Qualisys motion capture system, force plates, ladder and bicycle. By analyzing data from different individuals here, great potential information can be gained for predicting the recovery and progression of movement for patients. In the future, the development of personalized therapy protocols in rehabilitation with individualized progression can be offered. Optimum design parameters for the individual device and exercise device can be obtained, and if the relevant joints are supported with implants, it is possible to obtain the necessary boundary conditions for personalized implant design and to collect the necessary data for implant design. The Results and Discussion Chapter illustrates and tabulates the calculated results. In the Findings and Discussion section of the thesis, the calculated results of the study are included. This section provides a comprehensive analysis of the data collected, highlighting the observed patterns, trends, and variations in hip joint kinematics and kinetics during selected activities. The Discussion section delves into the significance of the findings by comparing the findings with the available literature, identifying similarities and differences, and offering possible explanations for observed variations.Master Thesis Investigation of Hip Joint Kinematics for Daily Life Activities(01. Izmir Institute of Technology, 2022) Tuna, Merve; Mihçin, ŞenayThe daily life activities of a population have a significant effect on hip joint due to the repetitiveness and difficulty levels. Therefore, daily life activity data is an important source for manufacturing successive and long-lasting implants for hip joint arthroplasty. In this study, the hip joint kinematics is investigated under six determined activity that is performed frequently by the Turkish population. The collected and processed data is used in a TUBITAK funded project to form a first national database for the Turkish people. The study first introduces the literature review on hip joint kinematics investigations for daily life activities. Thereafter, anatomy of the hip joint and motion capture techniques are explained. Experimental procedure, protocol, materials, methodology and data collection are explained in detail in the Methodology Chapter. This Chapter introduces the determined daily life activities, chosen motion capture system and post-processing tools for the inverse kinematic analysis. The Results and Discussion Chapter illustrates and tabulates the calculated results. Detailed explanations are made for discussing the results. The Conclusion Chapter summarizes the study.Master Thesis Design of Stacker Crane for Mini-Load Automated Storage and Retrieval Systems(Izmir Institute of Technology, 2022) Bekleviç, Mustafa; Mihçin, ŞenayThe objection of the thesis is to design and analyze a 3 degree of freedom stacker crane mechanism for Mini Load Automated Storage and Retrieval Systems. Automated Storage and Retrieval System (AS/RS) is an automated system in which the product of a company to be stored is placed in or retrieved from specified location on a rack system by means of computer aided mechanism which is nothing but a stacker crane. This study first introduces an inclusive literature review on AS/RSs. Several types of AS/RSs are examined and the differences between them are introduced. Additionally, several types of stacker cranes in the literature are also presented. Moreover, the linear motion systems used in similar mechanism are explained briefly in the chapter. In the design chapter of the thesis, theory of the stacker crane mechanism is introduced. A conceptual design is created and, elements and sub-sections of the desired mechanism are presented with the conceptual design of the mechanism. After the conceptual design, critical design calculations are performed approximately before the detailed design of the mechanism. Afterwards, the detailed design of the mechanism is created and calculations are verified due to detailed design. The detailed design of the mechanism is analyzed using Finite Element Analysis methods in the analysis chapter of the thesis. Analysis of critical components and critical sub-sections of the stacker crane mechanism are analyzed using Computer Aided Engineering program. Revises are made according to the results of the FEA and design is validated at the end. At the prototyping chapter of the thesis, the manufacturing studies of the mechanism are presented. Manufacturing stages are introduced and experiments of the sub-section of the mechanism are done.
