The finite element method solution of reaction-diffusion-advection equations in air pollution
Türk, Önder; Tezer-Sezgin, Münevver; Department of Scientific Computing (2008)
We consider the reaction-diffusion-advection (RDA) equations resulting in air pollution mod- eling problems. We employ the finite element method (FEM) for solving the RDA equations in two dimensions. Linear triangular finite elements are used in the discretization of problem domains. The instabilities occuring in the solution when the standard Galerkin finite element method is used, in advection or reaction dominated cases, are eliminated by using an adap- tive stabilized finite element method. In transient...
A Regime switching model for the temperature and pricing weather derivatives
Türkvatan, Aysun; Hayfavi, Azize; Omay, Tolga; Department of Financial Mathematics (2016)
Weather has an enormous impact on many institutions, for example, in energy, agriculture, or tourism sectors. For example, a gas provider faces the reduced demand in gas in case of hot winter. Weather derivatives can be used as a tool to manage the risk exposure towards adverse or unexpected weather conditions. Weather derivatives are the financial contracts with underlying depending on weather variables such as temperature,humidity,precipitationorsnow.

Design, construction and performance evaluation of a constant air volume device for HVAC systems
Kiper, Caner Ekin; Albayrak, Kahraman; Department of Mechanical Engineering (2018)
Everything that is used by humans in daily life is designed to increase the quality of life of people. This shows that comfort may be the last thing human beings are willing to give up. Heating, Ventilating and Air Conditioning (HVAC) systems are also designed to increase life standards in enclosed environments such as meeting rooms, offices, concert halls etc. People feel more comfortable when the ventilation system and ambient temperature is set properly. However, in some situations, setting the operating...
Forecasting of ionospheric electron density trough for characterization of aerospace medium
Kocabaş, Zeynep; Tulunay, Yurdanur; Department of Aerospace Engineering (2009)
Modeling the ionosphere, where the effects of solar dynamo becomes more effective to space based and ground borne activities, has an undeniable importance for telecommunication and navigation purposes. Mid-latitude electron density trough is an interesting phenomenon in characterizing the behavior of the ionosphere, especially during disturbed conditions. Modeling the mid-latitude electron density trough is a very popular research subject which has been studied by several researchers until now. In this work...
A new concept on sampling systems by air cannon application
Yünel, Ufuk; Hiçyılmaz, Cahit; Department of Mining Engineering (2004)
The most important criterion in industrial production processes is to control the required product quality and comply with the standards pre-described for the application during any stage of the process. This control begins from the entry of raw material to the plant and continues with pre-determined points. Mainly two different types of inspection and analyses are used to examine the material quality and content. These are physical and chemical analysis.In most of the production plants above mentioned anal...
