Design and processing of multi-phase high entropy alloys
The multi-principal element alloys (MPEAs) known as high- and medium-entropy alloys possess promising properties due to their highly distorted atomic crystal structures. Employing multi-elements as principal elements has ... -
Design and quantitative analysis of a pulse wave velocity blood-pressure measurement subsystem with multiple-subject controlled experiments
(2018-08)The main purpose of this study is to perform the pulse wave velocity (PWV) measurements with a new noninvasive optoelectronic continuous-time wearable sensor design and analyze the quantitative relation between the reference ... -
Design of high gain wideband quad-ridged horn antenna for emc testing
(2017-06)This thesis presents a design and simulation of high gain wideband quad-ridged circular horn antenna for Electromagnetic Compatibility (EMC) testing. The selected operating frequency range of the antenna is from 1 GHz to ... -
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 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 ...
