The infrared atmospheric background modeling can be considered as one of the important key factor to develop a successful target detection technique. During the infrared atmospheric background modeling, defining the input parameters of the atmospheric profile are very important for the calculations of the absorption, emission and scattering effects of the atmosphere. The main objective of this thesis is to find the answer for the question أis it possible to determine the أeffectiveؤ height range for the sea level midlatitude clear weather conditions in the three special wavelength bands, 1-3 ?m, 3-5 ?m, 8-12 ?m ?ؤ. The answer is important for three cases. These are to overcome the difficulties of finding all the parameters of the new atmospheric profile, to determine the dominant height range for the midlatitude region, and to shorten the time of the calculations of infrared background processes. In this study, it has been shown that it should be possible to determine the effective height range for sea level midlatitude clear weather conditions in the three special wavelength bands. As a result of this study it is shown that a new atmosphere model can be constructed more easily by overcoming the difficulties of finding all the parameters of the new atmospheric profile for the sea level clear weather midlatitude regions in a short time respectively. In this study the infrared radiation flux below 5 % difference between the whole, 100 km, and the effective height ranges is accepted.

Investigation of radiative heat transfer in freeboard of a 0.3 MWt AFBC test rig Kozan, M; Selçuk, Nevin (2000-01-01) Based on the analysis of measured data on flow rates, concentrations and temperatures taken during steady state operation of a lignite-fired 0.3 MWt Atmospheric Fluidized Bed Combustor (AFBC) test rig, radiative exchange in freeboard of the combustor was modeled by using a well-stirred enclosure model in conjunction with Radiosity-Irradiation Method (RIM). Radiative properties of the particle laden combustion gases were calculated by assuming grey radiation behaviour for both particles and gas, and using Le...
A concise analytical treatment of elastic-plastic bending of a strain hardening curved beam Eraslan, Ahmet Nedim (Wiley, 2008-08-01) Plane stress and plane strain analytical solutions to partially plastic deformation of a curved beam are presented. The beam has a narrow rectangular cross section and it is subjected to couples at its end sections prevailing pure bending conditions. The analysis is based on Tresca's yield criterion, its associated flow rule and linear strain hardening material behavior. The solutions are verified in comparison to the ones available in the literature. It is shown that plane stress and plane strain solutions...
An Upper Bound for Limited Rate Feedback MIMO Capacity Güvensen, Gökhan Muzaffer; Yılmaz, Ali Özgür (Institute of Electrical and Electronics Engineers (IEEE), 2009-06-01) We develop a technique to upper bound the point-to-point MIMO limited rate feedback (LRF) capacity under a wide class of vector quantization schemes. The upper bound turns out to be tight and can also be used to obtain an absolute upper bound by using a bounding distribution for Grassmannian beamforming. The bounding technique can be applied to other problems requiring the exact evaluation of the expected value of matrix determinant.
A Hybrid Computational Method Based on Convex Optimization for Outlier Problems: Application to Earthquake Ground Motion Prediction Yerlikaya-Ozkurt, Fatma; Askan Gündoğan, Ayşegül; Weber, Gerhard-Wilhelm (Vilnius University Press, 2016-01-01) Statistical modelling plays a central role for any prediction problem of interest. However, predictive models may give misleading results when the data contain outliers. In many real -world applications, it is important to identify and treat the outliers without direct elimination. To handle such issues, a hybrid computational method based on conic quadratic programming is introduced and employed on earthquake ground motion dataset. This method aims to minimize the impact of the outliers on regression estim...
A Computationally Efficient Appearance-Based Algorithm for Geospatial Object Detection Arslan, Duygu; Alatan, Abdullah Aydın (2012-04-27) A computationally efficient appearance-based algorithm for geospatial object detection is presented and evaluated specifically for aircraft detection from satellite imagery. An aircraft operator exploiting the edge information via gray level differences between the aircraft and its background is constructed with Haar-like polygon regions by using the shape information of the aircraft as an invariant. Fast evaluation of the aircraft operator is achieved by means of integral image. Rotated integral images are...
