A Density Functional Theory Study of Structure of Phosphonic Acid

The molecular structure of the stable conformation of phosphonic acid in gas phase has beencomputed by employing complete geometry optimization in Density Functional Theory(DFT) methods. The methods used for calculations are B3LYP, BP86 and B3PW91 that havebeen studied in two series of basis sets: D95** and 6-31+G(d,p) for hydrogen and oxygenatoms; LANL2DZ for phosphorus. Bond lengths and angle...

Sociocultural Identity in TEFL Textbooks: A Systemic Functional ‎Analysis

This study aimed at investigating shades of identity in TEFL textbooks. Most identity studies have focused on authors as knowledge producers. They have neglected authors' roles in constructing identity. Further, few scholars have considered disciplinary specific textbooks in their analyses of identity. Trying to bridge these gaps, we applied Halliday’s Systemic Functional Linguistics to investi...

Fundamentals of Media Theory

Media theory is a new branch of discrete applied mathematics originally developed in mid-nineties to deal with stochastic evolution of preference relations in political science and mathematical psychology. The theory focuses on a particular semigroup of ‘messages’ acting as transformations of a set of ‘states’, called a ‘medium’, whose axioms are both strong and natural. The term ‘medium’ stems...

Fundamentals of Control Theory

Control theory is the discipline that concerns itself with the response of dynamical systems to input. Control theory is a eld that spans both mathematics and engineering as it nds the vast majority of its applications while providing many complex problems as the topic of much mathematical research. Such problems often deal with questions such as stability, robustness (tolerance in variation of...
