Students Prjoect (Fall 2019-2020)- Mathematical Modeling of a class of Composite Islamic Geometric Patters

Student

Amal Rabah (U15106248)

Abstract

Islamic designs encompasses the visual arts produced in Islamic world. In this research we will present symmetrical composite designs using Islamic geometric patterns by constructing graphs on Unit Circle.

Students Prjoect (Fall 2019-2020)-Edge Metric Dimension

Student

Abstract

The edge metric dimension of a graph is introduced based on the distance of edges of the graph , we will compute the edge metric dimension of chain of cycle for even , odd  , and alternating cycle wih odd and even and we will prove that they have edim =2.

Abstract

Testing relationships between categorical or qualitative variables for real-life is one of the important approaches of statistics for analyzing data which is widely used today.

Chi square distribution is a type of cumulative probability distribution, which provide the probability of every possible value that may occur. Chi square test is a statistical procedure derived from the chi-square distribution to compare the goodness of fit of theoretical and observed frequency distributions or to compare nominal data derived from unmatched groups of subjects.

In this project, we thoroughly demonstrated the concept of statistics and the main areas and types of statistics. The element of hypotheses testing with the methods concerning in p-value approach to specify the rejection and non-rejection regions then determine the types of errors will occur when reject or not reject. Explain Proportion for population in more details and present the procedure to perform tests of hypotheses for one sample and two samples both provided by a complete example. Moreover, we will discuss the case where there are more than two samples which is the Chi-square test, and this is the main topic of this research. We will discuss the chi square distribution, contingency table and goodness of fit test. A case study is included and used to apply all the illustrated theory using SPSS software. The results are shown in complete details.

Project (Fall 2018-2019): Distribution Theory of Simple Linear Regression with Applications
Student: Mariam A. Orabi U14123143

Abstract: Regression analysis is a statistical methodology that utilizes the relation between two or more variables so that one variable can be predicted from the other, or the others (Neter, Kutner, Nachtsheim and Wasserman, 1996). Building valid models for real-life data is one of the most important approaches of statistics for analyzing data which is widely used today. Successful applications require understanding of both the underlying theory and the practical problems that are encountered when building models for real-life data. The simplest form of regression is the simple linear regression, which considers only one explanatory variable linearly related to the response variable. Understanding simple linear regression enables the reader to look at many aspects of regression in the simplest possible setting. In this project, we thoroughly demonstrated the concept of simple linear regression. The model parameters are estimated using two methods, namely, least squares method and maximum likelihood method. It is shown that the estimators are equal in both methods, and proven to be good estimates, for which, the proof of Gauss-Markov theorem is provided. In order to check the validity of the model, statistical inferences about the parameters along with diagnostic methods to assure the validity of the model’s assumptions are explained. When encountering specific problems, suggestions and some transformations are provided to overcome such problems. An example is included, and used to apply all the illustrated theory using RStudio software. The R-code and the results are shown in complete details.
