A custom-design atmospheric channel emulator for the performance evaluation of free space optical communication systems
Kebapçı, Burak (2017-08)The properties of atmospheric chamber and measurement methods that are used in this system are explained and analyzed in detail. We present our own custom design atmospheric channel emulator for FSO system evaluations and ... -
Decomposing time series data via mixed integer programming
Gözüyılmaz, Şeyma (2020-01-13)Decomposing time series into seasonality, trend, and remainder reveals underlying insights to be used in forecasting and anomaly detection. Although there are several decomposition methods, no method guarantees all of the ... -
A decomposition-based metaheuristic approach for solving the rapid needs assessment routing problem
Mıhçıoğlu, Yurtsev (2021-01-18)This study proposes a decomposition-based tabu search algorithm for a multi-cover routing problem (MCRP), which aims to classify and evaluate the impacts of the disaster in different sites and the needs of different community ... -
Deep reinforcement learning approach for trading automation in the stock market
Deep Reinforcement Learning (DRL) algorithms can scale to previously intractable problems. The automation of profit generation in the stock market is possible using DRL, by combining the financial assets price "prediction" ... -
Design and implementation of a data stream management system with advanced complex event processing capabilities
Ölmezoğulları, Erdi (2013-06)The world has seen proliferation of data stream applications over the last years. These applications include computer network monitoring, Radio Frequency Identication (RFID)-based supply chain and traffic management systems, ... -
Design and implementation of a robust control scheme for a smart joint
Jabeen, Saher (2017-01)The invention of biomedical tools has made medical treatments more convenient; however, manual insertion of these tools requires years of practice and erroneous insertion into the body may cause ruptures and bleeding. ... -
Design and modeling of a parallel robot for ultrasound guided percutaneous needle interventions
Orhan, Sabri Orçun (2015-08)Percutaneous needle operations need precise positioning in order to collect samples for diagnosis. Due to their robustness, accuracy robotic systems started to take place in medical procedures. Research that have been done ... -
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
Erkurşun, Burcu (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
Solak, Bekir (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 ... -
Determination of effective breadth width of stiffened steel plate structures based on nonlinear finite element analysis
Kılıç, Burak Talha (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
Fidan, Güven (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
Tekbaş, Gökhan (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
Ersoy, Onur (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
Yıldırım, Mehmet Can (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
Siddiqui, Faizan Pervez (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
Vahidyeganeh, Ali (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 ...
