CHAPTER 1 . 1 The Problem of Theory in Gerontology Today

Practical Step towards Sampling in Qualitative Research; Focused on Grounded Theory

Today, there is a growing trend towards qualitative research in different areas of academic investigations. However, students face difficulties in deciding on qualitative methods of research, because most of the literature on qualitative research focuses on the philosophical and theoretical aspects, and they hardly offer any practical guidelines. This problem is rooted in the essence of qualita...

Role of Endogenous Development in Informal Habitation: An Analytical Study

Today, most of the big cities or metropolises around the world have been encountering with the problem of informal habitation. The present study, thus, tries to focus on the role of endogenous development in such type of habitation process. For that matter, the paper takes into account architectural programming and urbanism as its theoretical framework because the endogenous development is rela...

Reliability estimation of Iran's power network

Today, the electricity power system is the most complicated engineering system has ever been made. The integrated power generating stations with power transmission lines has created a network, called complex power network. The reliability estimation of such complex power networks is a very challenging problem, as one cannot find any immediate solution methods in current literature. In this pape...

On Generalization of Sturm-Liouville Theory for Fractional Bessel Operator

In this paper, we give the spectral theory for eigenvalues and eigenfunctions of a boundary value problem consisting of the linear fractional Bessel operator. Moreover, we show that this operator is self-adjoint, the eigenvalues of the problem are real, and the corresponding eigenfunctions are orthogonal. In this paper, we give the spectral theory for eigenvalues and eigenfunctions...
