Due to recent evolution of the COVID-19 outbreak, accurate mathematical modelling to capture the dynamics of disease transmission is of vital importance. Since the availability and quality of data differs from region to region, it is very difficult to develop an accurate model from the global perspective. Nevertheless, local predictive models can be developed by collecting data from certain regions. In this thesis, a modified version of Susceptible-Exposed-Infected-Recovered-Dead (SEIRD) differential model is proposed for the analysis and forecast of COVID-19 spread. Parameter estimation of the model is the first step of analysis which is carried out by fitting the model to available data as good as possible in the sense of least squares. In second step of analysis, simulations are performed by using the optimal values of parameters. Through numerical simulations, the effects of public measures, such as isolation, social distancing on the dynamics of COVID-19 outbreak are observed. The model is applied for the COVID-19 outbreak in Turkey, Italy, and Spain. Time to reach the peak, total infected, recovered and dead cases are compared with real data and found to be in good agreement for all the countries.

A multi-layered graphical model of the relation among SNPS, GENES, and pathways based on subgraph search
Ersoy, Gökhan; Aydın Son, Yeşim; Can, Tolga; Department of Bioinformatics (2015)
The analysis of Single Nucleotide Polymorphisms (SNPs) through Genome Wide Association Studies (GWAS) presents great potential for describing disease loci and gaining insight into the underlying etiology of diseases. Recently described combined p-value approach allows identification of associations at gene and pathway level. The integrated programs like METU-SNP produce simple lists of either SNP id/gene id/pathway title and their p-values and significance status or SNP id/disease id/pathway information. In...
A mathematical model for human-to-human transmission of COVID-19: A case study for Turkey’s data
Cengizci, Süleyman; Cengizci, Aslıhan Dursun; Uğur, Ömür (2021-01-01)
In this study, a mathematical model for simulating the human-to-human transmission of the novel coronavirus disease (COVID-19) is presented for Turkey’s data. For this purpose, the total population is classified into eight epidemiological compartments, including the super-spreaders. The local stability and sensitivity analysis in terms of the model parameters are discussed, and the basic reproduction number, R0, is derived. The system of nonlinear ordinary differential equations is solved by using the Galer...
A novel SVM-ID3 Hybrid Feature Selection Method to Build a Disease Model for Melanoma using Integrated Genotyping and Phenotype Data from dbGaP
Aydın Son, Yeşim (2014-09-03)
The relations between Single Nucleotide Polymorphism (SNP) and complex diseases are likely to be non-linear and require analysis of the high dimensional data. Previous studies in the field mostly focus on genotyping and effects of various phenotypes are not considered. To fill this gap a hybrid feature selection model of support vector machine and decision tree has been designed. The designed method is tested on melanoma. We were able to select phenotypic features such as moles and dysplastic nevi, and SNPs...
A test for detecting etiologic heterogeneity in epidemiological studies
Karagulle, S.; Kalaylıoğlu Akyıldız, Zeynep Işıl (2016-02-17)
Current statistical methods for analyzing epidemiological data with disease subtype information allow us to acquire knowledge not only for risk factor-disease subtype association but also, on a more profound account, heterogeneity in these associations by multiple disease characteristics (so-called etiologic heterogeneity of the disease). Current interest, particularly in cancer epidemiology, lies in obtaining a valid p-value for testing the hypothesis whether a particular cancer is etiologically heterogene...
