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 ... -
A distributed blacklisting protocol for iot device classification using the hashgraph consensus algorithm
Industrial applications require highly reliable, secure, low-power and low-delay communications. However, wireless communication links in the industrial environment suffer from various channel impairments which can compromise ... -
Diversity techniques for ultraviolet communications
(2016-08)Strong molecular and aerosol scattering in ultraviolet (UV) wavelengths enable mechanisms where transmitter can communicate with the receiver in the absence of line of sight (LOS) link. Recent advances in solid state ... -
Diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(2016-08)Cooperative communication (CC) exploits the broadcasting nature of wireless transmission and creates a distributed multiple-input multiple-output (MIMO) system among the wireless nodes which are physically separated from ... -
Do pension funds provide liquidity: Lessons from em countries
(2017-01)In response to the financial crisis, there has been increased attention on the importance of the long-term investors for financial stability. We contribute to this literature by investigating the role of pension funds on ... -

(2018-05)A momentum strategy is applied on the 5-year and the 10-year maturity Turkish bonds between March 2010 and August 2017 with various look-back periods. The U.S. 10-year maturity bond yield and the Istanbul Stock Exchange ... -
Dopamine detection using mercaptopropionic acid and cysteamine for electrodes surface modification
(2017-05)This research work emphasizes on main objective of dopamine detection using electrochemical detection analysis. Dopamine is an electrochemical neurotransmittor and is an essential part in human body for many decisions. It ... -
Durability testing and vibration characterization of an electric vehicle battery
Although the electrical system is important in the development of electric vehicles, the durability of the battery against mechanical loads and the performance of the battery against shock reactions are just as important. ... -
A dyadic analysis of the link between couples' perfectionism and attachment behaviors
Recently, perfectionism has been a more important construct due to its links with adverse individual as well as relational outcomes. In this regard, perfectionism's association with people's actions, particularly with the ... -
The dynamics of asset swap spread in Turkey
(2018-05)In response to the financial crisis, investors have been increasingly sensitive to the evolution of swap spreads, as a rising proportion of their portfolio is constituted by emerging markets debt instruments. I provide two ... -
An ecologically valid reference frame for perspective invariant action recognition
In robotics, objects and body parts can be represented in various coordinate frames to ease computation. In biological systems, body or body part centered coordinate frames have been proposed as possible reference frames ... -
Economic lot sizing problem with tank scheduling
(2021-08)In this study, we consider an Economic Lot sizing Problem with Tank Scheduling (ELSTS). The problem is a real-world problem, which is generally found in fermented beverage and food facilities. A facility might produce an ...
