Development of a single-chip visible light communication receiver
The VLC has drawn the attention in the last decade, which is simply based on the data transmission over the visible light (400nm-700nm). It is considered as an alternative to RF-based technologies and offers unlicensed ... -
Development of a solid state spot welding technique for the manufacturing of detect free joints
(2019-06)Development of a Solid State Spot Welding Technique for the Manufacturing of Defect Free Joints.--Friction stir spot welding (FSSW) processing is a recently developed process for joining hard weldability materials, which ... -
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 ... -
Dexterous manipulation with a robotic hand
(2017-06)In robotics, flexible and the dexterous manipulation are one of the most desired type of skills. To this end, we investigate dexterous manipulation skills on an anthropomorphic robot hand. In the first part of the study, ... -
Die-swelling phenomenon in rubber weatherstrip manufacturing under real process conditions imposed in a commercial extrusion line
(2021-06-11)The weather-strip manufacturers aim to reduce one of their main costs, trial scrap, to be competitive and to have a lower carbon foot. Annual scrap rates of sealing systems are mainly caused by extrusion dies and ... -
Digital maturity measurement based on the stages of digital business transformation a study in the automotive sales and aftersales sector
Digital transformation is the change of socio-economic structures such as business models, supply chains, platforms, or ecosystems as a consequence of the use of digital technology. Consistent with the previous research ... -
