Monitoring Financial Ratios in Enterprise Stewardship Model using Functional Analysis
, M.Sc. Thesis Sharif University of Technology ; Akhavan Niaki, Mohammad Taghi (Supervisor)
Abstract
In recent years, with the expansion of the use of information technology and information systems, data mining has attracted the attention of organizations. Functional analysis is one of the domains in data mining. This analysis can provide important information for companies in various fields. Functional analysis involves the development of statistical approaches for functional data. Studies in this analysis have covered a wide range of areas, including finance. Financial analysis is very important in business analysis. One of the tools used to analyze companies is the analysis of financial ratios. In fact, financial ratios reveal important realities in relation to the operations and...
Pricing of Service Advance Sale System with Risk Consideration
, M.Sc. Thesis Sharif University of Technology ; Sheikhzadeh, Mehdi (Supervisor)
Abstract
Today service sector is an important part of economy in many countries and it accounts for a great portion of GDP in developed countries. The importance of the service sector has led to an expansion in research worldwide on services. Service has some unique specifications that make it different from product and research in this field is more challenging than production field. Pricing is one of the great challenges in service sector. Due to its intangibility and perishability, managing and pricing of service is complicated and ervice firms consistently seek for method and approaches to better manage their demand, capacity and prices. Advance sale is an effective approach which is commonly...
The Synthesis of Graphene-Nanobubbles and Investigation of their Potential Synergistic Effect on Bacterial Cells
, Ph.D. Dissertation Sharif University of Technology ; Akhavan, Omid (Supervisor) ; Maddah Hosseini, Hamid Reza (Supervisor) ; Bakhsi, Bita (Co-Supervisor)
Abstract
Recently, nanotechnology has promised to create and/ or improve therapeutic methods which in turn remain minimum side effects by employing synergistic effects of nanostructures. However, a comprehensive understanding of the interactions between nanostructures and building blocks of the biological systems (cells) is essential to create innovative therapeutic methods and compound and also predict their behavior for upcoming applications. In this thesis for the first time, synergistic effects of graphene-nanobubbles in interactions with bacterial (as the simplest model) cells were investigated. Therefore, at the first step, production of nanobubbles (NBs) in the presence of two-dimensional...
