Modeling and simulation of a small-sized Tiltrotor UAV
Çakıcı, Ferit; Leblebicioğlu, Mehmet Kemal (2012-10-01)
Unmanned aerial vehicles (UAVs) are remotely piloted or self-piloted aircrafts that can carry cameras, sensors, communication equipment and other payloads. Tiltrotor UAVs provide a unique platform that fulfills the needs for ever-changing mission requirements, by combining the desired features of hovering like a helicopter and reaching high forward speeds like an airplane, which might be a force multiplier in the battlefield. In this paper, the conceptual design and aerodynamical model of a realizable small...
Modeling of activated sludge process by using artificial neural networks
Moral, Hakan; Gökçay, Celal Ferdi; Department of Environmental Engineering (2004)
Current activated sludge models are deterministic in character and are constructed by basing on the fundamental biokinetics. However, calibrating these models are extremely time consuming and laborious. An easy-to-calibrate and user friendly computer model, one of the artificial intelligence techniques, Artificial Neural Networks (ANNs) were used in this study. These models can be used not only directly as a substitute for deterministic models but also can be plugged into the system as error predictors. Thr...
Modeling and Analysis of a Microfluidic Capillary Valve
Yıldırım, Ender (2017-04-01)
Here, a numerical model for analysis of a capillary valve for use in microfluidic devices was presented. Capillary valves are preferred especially in passive microfluidic systems, where the capillary forces dominate the liquid motion, to manipulate the flow. The capillary valve in this work, was formed by the sudden expansion of a rectangular microchannel to an opening, whose depth and width are larger than the height and the width of the channel respectively. Noting that there was no available analytical m...
Modeling and simulation of photobioreactors for biological hydrogen production
Androga, Dominic Deo; Eroğlu, İnci; Uyar, Başar; Department of Biotechnology (2014)
In applications of photofermentative hydrogen production, maintaining optimal temperature, feed composition, pH range and light intensity is the most critical objective for growth and proper functioning of the photosynthetic bacteria. Response Surface Methodology was applied to optimize temperature and light intensity for indoor hydrogen production using Rhodobacter capsulatus. Surface and contour plots of the regressions models developed revealed a maximum hydrogen production rate of 0.566 mol H2/m3/h at 2...
