Implementation of a low-cost smart camera apllication on a cots system
Baykent, Hayri Kerem; Akar, Gözde; Department of Electrical and Electronics Engineering (2011)
The objective of this study is to implement a low-cost smart camera application on a Commercial off the Shelf system that is based on Texas Instrument’s DM3730 System on Chip processor. Although there are different architectures for smart camera applications, ARM plus DSP based System on Chip architecture is selected for implementation because of its different core abilities. Beagleboard-XM platform that has an ARM plus DSP based System on Chip processor is chosen as Commercial off the Shelf platform. Durin...
Design of reflective and antireflective coatings for space applications
Eroğlu, Hüseyin Cüneyt; Esendemir, Akif; Department of Physics (2009)
In order to improve the efficiency of various optical surfaces, optical coatings are used. Optical coating is a process of depositing a thin layer of a material on an optical component such as mirror or lens to change reflectance or transmittance. There are two main types of coatings namely; reflective and antireflective (AR) Coatings. Reflective and antireflective coatings have long been developed for a variety of applications in all aspects of use; for optical and electro-optical systems in telecommunicat...
Utilization of neural networks for simulation of vehicle induced flow in tunnel systems
Koç, Gencer; Albayrak, Kahraman; Sert, Cüneyt; Department of Mechanical Engineering (2012)
Air velocities induced by underground vehicles in complex metro systems are obtained using artificial neural networks. Complex tunnel shaft-systems with any number of tunnels and shafts and with most of the practically possible geometries encountered in underground structures can be simulated with the proposed method. A single neural network, of type feed-forward back propagation, with a single hidden layer is trained for modelling a single tunnel segment. Train and tunnel parameters that have influence on ...

Squeeze film damper is a widely used nonlinear element in rotor-bearing systems. The dynamic behavior of the rotor-bearing system supported by the squeeze film damper must be investigated for proper design and analysis. Nonlinear vibration response of rotor systems supported by squeeze film damper due to unbalance is investigated. The system rotordynamic model is developed using 1D Timoshenko beam elements. Three types of modeling are performed for SFD. The nonlinear SFD models are based on the analytical s...

Natural and synthetic borates find widespread use in different industries. Among synthetic borates, the lithium borate compounds, lithium tetraborate (Li2B4O7) and lithium triborate (LiB3O5) are very important due to their thermoluminescence (TL) properties and usage potential in radiational dosimetry. It is possible to define the phenomenon of thermoluminescence (TL) or thermally stimulated luminescence (TSL) in several different ways, the simplest of which is emission of light when an irradiated material ...
