Improving the sight efficiency of visually impaired people with games that can be played with motion capture systems
Konya, Oğuz; Çağıltay, Kürşat; Department of Game Technologies (2014)
This thesis researches whether the life skills and eye-body coordination of the visually impaired children can be improved through the use of video games which use motion capture system as input. It also researches what kind of video games can be developed and how they can be used in order to provide benefit to visually impaired children. This study was conducted as a mix of qualitative and quantitative studies. It was carried out in six phases. In the first phase, the psychomotor development areas of the v...
Improving the trajectory tracking performance of autonomous orchard vehicles using wheel slip compensation
BAYAR, Gokhan; Bergerman, Marcel; Konukseven, Erhan İlhan; Koku, Ahmet Buğra (2016-06-01)
In this paper, the effects of wheel slip estimation and compensation of trajectory tracking for orchard applications were investigated. A slippage estimator was developed and adapted into a car-like robot model. Steering and velocity commands were generated using a model-based control approach. The whole system was implemented and tested on an autonomous orchard vehicle that has steerable front wheels and actuated rear wheels. A high accuracy positioning system was used to estimate the longitudinal and late...
Improving Oil-Rate Estimate in Capacitance/Resistance Modeling Using the Y-Function Method for Reservoirs Under Waterflood
Temizel, Cenk; Artun, Emre; Yang, Zhengming (Society of Petroleum Engineers (SPE), 2019-08-01)
Capacitance/resistance modeling (CRM) is an empirical waterflood modeling technique based on the signal correlations between injection rates and gross production rates. CRM can satisfactorily estimate the gross (liquid) production rate. The oil-production-rate forecast is based on fitting the empirical oil fractional-flow model, the Leverett (1941) oil fractional-flow model, or the Koval (1963) model to the historical production data. We observed that the oil-production-rate forecast in this approach is les...
Improving operational performance of antennas on complex platforms by arranging their placements
Bayseferoğulları, Can; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2010)
The aim of this thesis is to improve the operational performance of the communication antennas mounted on complex platforms such as aircrafts and warships by arranging placements of these antennas. Towards this aim, primarily, in order to gain insight on the influence of geometrically simple structures composing the platform on antenna performance, a quarter wavelength monopole antenna placed at the center of a finite square ground plane is studied by using uniform Geometrical Theory of Diffraction (GTD). B...
Improving ductility and shear capacity of reinforced concrete columns with carbon fiber reinforced polymer
Özcan, Okan; Özcebe, Güney; Department of Civil Engineering (2009)
The performance of reinforced concrete (RC) columns during recent earthquakes has clearly demonstrated the possible failures associated with inadequate confining reinforcement. The confinement reinforcement requirements of older codes were less stringent than present standards. Many studies were conducted by applying different retrofitting techniques for RC columns that have inadequate confinement reinforcement. A new retrofitting technique by means of Carbon Fiber Reinforced Polymer (CFRP) was developed an...
