Design of vivaldi antenna operating in two frequency bands with distinct polarizations
This thesis presents a novel dual-polarized antenna design based on two orthogonally place Vivaldi antenna elements and are driven by a specially designed feeding network that splits incoming signal into two wherein one ... -
Design, development, and real-life implementation of a high power quadruped robot
This thesis presents the design, development, and experimental test of a quadruped with high power-to-weight ratio. In this thesis, three design processes are studied, namely, actuator design, leg mechanism design and torso ... -
Determinants of liquidity adequacy ratio: An empirical study on Turkish banks
Liquidity and liquidity risk is a phenomenon that has important consequences in the management of banks. In addition, liquidity risk has an important role in banking crises. With the new regulations created, liquidity ... -
Determination of effective breadth width of stiffened steel plate structures based on nonlinear finite element analysis
(2019-08-19)An economical and effective design of plates loaded by out-of-plane loads such as pressure or blast can be obtained by using stiffeners instead of increasing plate thickness. Therefore, stiffened steel plates are widely ... -
Determining thermal comfort in built environment using computational fluid dynamics simulations
(2017-06)In this thesis, three-dimensional time-dependent Thermal Comfort (TC) conditions in an occupied room is investigated and determined. The room is considered with furniture of varying materials (i.e. steel, wood, etc.) and ... -
Developing a BIM-based tool for automated fall safety review
(2020-01-06)Construction sites are globally known to be amongst the most dangerous working environments. Ensuring safety at sites can be difficult because it is not affected by just one parameter; but it is governed by the behavior ... -
Development and control of a parallel endoscopic surgical robot platform for beating heart procedures
(2021-06-16)Minimally Invasive Robotic Surgery focuses on performing surgeries using advanced robotic tools through small incisions. Taking advantage of these advanced tools and control methods, challenging surgeries such as ... -
Development of a torque-controllable lower extremity exoskeleton for crutch-free 3D walking support
(2018-12-24)Spinal cord paralysis is a condition, which is formed due to full or partial loss of sensorimotor and autonomous functionalities of the spinal cord. Paraplegia is a type of spinal cord injury which causes functionality ... -
Development of a torque-controllable upper limb exoskeleton for industrial applications
Chronic upper body pain and injuries are undesirable physical disorders that result from regular exposure to external forces that strain the musculoskeletal system. These symptoms reduce both the quality of life and ... -
Development of an accelerated Monte Carlo ray tracing based radiation heat transfer solver
(2017-07)The Monte Carlo ray tracing (MCRT) is a semi-analytical stochastic method for the solution of radiative transfer equation (RTE). However, its high computation cost prevents its extensive use. In this study, an accelerated ... -
Development of antagonistically actuated active joints with shape memory aloys
(2017-01)The focus of this research work is the development of an active joint antagonistically actuated by shape memory alloys (SMA). Due to their high force to mass ratio these identified as excellent actuator candidates for ... -
Development of multifunctional tick repellent textiles
(2016-09)This thesis focuses on smart textile manufacturing with tick repellency through encapsulation of the natural extracts and applying them onto the fabric surfaces. Tick-borne encephalitis (TBE) is a human viral infectious ... -
Development of multimodal expressions of space in speech and gesture: the case of sagittal and topological spatial relations
Previous literature has shown that learning to communicate about space follows a lengthy timetable. However, prior work has shown that children can express some concepts, including spatial relations, in gestures prior to ... -
Development of nano structured photo-catalytic textile materials
(2017-07)This study focuses on assisting problems which have delayed the commercialization of the photocatalytic textile applications by the following innovative technological developments related to photocatalytic compounds; (i) ... -
Development of novel methodologies for rotational dynamics applications
(2020-12-31)In this thesis, a novel methodology is proposed to determine the parameters of a rotating unbalance in a rotor-bearing system. For that purpose, the weighted sum of squared difference between the analytical and predicted ... -
Development of novel methodologies for the damage detection in mechanical systems
(2020-12-31)The present study examines the capability of various optimization algorithms and proposes novel hybrid algorithms for the more precise prediction of open-edge cracks in mechanical systems. The natural frequencies of the ... -
Development of the calibration scheme and system integration of the Ozyegin biopsy robot (OBR)
(2016-08)Imaging systems can fail to visualize cancerous tissues for proper diagnosis. Needle based procedures, like biopsies, increase the chances of accurate diagnosis of tumors. These procedures also have applications in minimally ... -
Development of two-phase biological self-healing agents for cement-based mortar
(2020-01-13)Factors affecting durability of concrete structures are generally associated with each other. Due to its brittle nature, concrete can crack under stress and these cracks can decrease the service life of concrete structures. ... -
Development of various corner-lit backlighting concepts in an advanced smart LED TV
(2015-01)CCFL (Cold Cathode Florescent Lamp) based LCD (Liquid Crystal Display) TVs are replaced by Smart LED TVs with the help of recent improvements of the LED (Light Emitting Diode), electronics and information technologies. ... -
Devletin yenilenebilir enerji kaynaklı elektrik enerjisini arz etme yükümlülüğü
(2017)Elektrik enerjisinin hayatımızdaki yeri ve önemi tartışmasızdır. Elektrik enerjisinin arzı, sürekliliği, fiyatı, ulaşılabilirlik açısından önemlidir. Fakat bir diğer önemli husus da elektrik enerjisinin kaynağıdır. Elektrik ...
