Metamodeling complex systems using linear and nonlinear regression methods
Kartal, Elçin; Batmaz, İnci; Department of Statistics (2007)
Metamodeling is a very popular approach for the approximation of complex systems. Metamodeling techniques can be categorized according to the type of regression method employed as linear and nonlinear models. The Response Surface Methodology (RSM) is an example of linear regression. In classical RSM metamodels, parameters are estimated using the Least Squares (LS) Method. Robust regression techniques, such as Least Absolute Deviation (LAD) and M-regression, are also considered in this study due to the outli...
A comprehensive review of data mining applications in quality improvement and a case study
Güntürkün, Fatma; Batmaz, İnci; Department of Statistics (2007)
In today‘s world, knowledge is the most powerful factor for the success of the organizations. One of the most important resources to reach this knowledge is the huge data stored in their databases. In the analysis of this data, DM techniques are essentially used. In this thesis, firstly, a comprehensive literature review on DM techniques for the quality improvement in manufacturing is presented. Then one of these techniques is applied on a case study. In the case study, the customer quality perception data ...

In heavily settled areas, deformations induced by the tunnel excavation may cause serious damage to nearby structures. Therefore, it is necessary to study effective means of controlling tunnel induced deformations. The main parameters affecting the failure and deformation state of the soil around a circular underground opening are the physical characteristics of the soil, the diameter of the opening, and the support pressure. In this study, 3-Dimensional (3D) FDM analyses were conducted to assess tunneling ...
Comparative statistical microarray analysis of yeast data under heat shock stress
Varol, Duygu; Purutçuoğlu Gazi, Vilda; Yılmaz, Remziye; Department of Statistics (2014)
The microarray technology is one of the widely used experimental methods in biological and biochemical sciences. By this innovation, a number of genes can be analyzed simultaneously by means of statistical methods. Hereby in this study we analyze a new one-channel microarray dataset that is measured to investigate the changes in heat shock stress of yeast. The data that are generated in the Molecular Biology and Biotechnology R-D Center at the Middle East Technical University has not been evaluated yet in d...
Gravitational waves and gravitational memory
Korkmaz, Ali; Tekin, Bayram; Department of Physics (2018)
We study the gravitational waves produced by compact binary systems in the linear regime of massless general relativity and calculate the gravitational memory produced by these waves on a detector.
