Theory building is a central goal in most research disciplines, and it difficult to overstate the importance of theory endeavor. This paper builds on study several disciplines so as to: (1) synthesize into framework, (2) support development evaluation project management research. Four types theory, prescriptive, descriptive, predictive, practice, are presented. 'classic' papers used retrospecti...

Vibration of double-graphene sheet-system is considered in this study. Graphene sheets are coupled by Pasternak elastic medium. Classic and Mindlin plate theories are utilized for modeling the coupled system. Upper sheet carries a moving mass. Governing equations are derived using energy method and Hamilton’s principle considering surface stress effects and nonlocal parameter.  Using Galerkin m...

In recent years, many developments have been made in matching theory and its applications to market design. This paper surveys them and suggests possible research directions. The main focus is on the advances in matching theory that try to solve market design problems in practical markets where the classic theory is inapplicable. Specifically, we discuss the recent theory of matching in large m...

Introduction: Citation analysis is a suitable way to help us to identify research trends within a specific topic. The purpose of this study was to identify the 100 most cited articles in the field of dentistry published over the past 67 years. Methods: A comprehensive list of the most cited articles in dentistry was compiled using ISI Web of Science. The characteristics including number of cita...

In 1971 Abdel R. Omran published his classic paper on the theory of epidemiologic transition. By the mid-1990s, it had become something of a citation classic and was understood as a theoretical statement about the shift from infectious to chronic diseases that supposedly accompanies modernization. However, Omran himself was not directly concerned with the rise of chronic disease; his theory was...

Claude Shannon’s classic 1948 paper introduced a general theory for measuring the transmission of information from a source, across a noisy channel, to a receiver (Figure 1). This theory became known as information theory. Shannon illustrated his theory with such examples as messages sent over telegraph lines by Morse code. But the same principles can be applied to neurons: a neuron transmits i...

cooperation is the foundation of many protocols in wireless networks. without cooperation, the performance of a network significantly decreases. hence, all nodes in traditional networks are required to cooperate with each other. in this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whether to cooper...
