Intelligent Applications for Heterogeneous System Modeling and Design
To meet the challenge of conducting quantitative analysis at the early stage of the system development process, this chapter introduces an extensive framework for performance modeling of a distributed system. The goal of the performance modeling framework is the assessment of the non-functional properties of the distributed system at an early stage based on the system's functional description and deployment mapping of service components over an execution environment. System's functional description with deployment mapping has been specified using UML. To analyze the correctness of the UML specification style, we have used temporal logic, specifically cTLA, to formalize the UML model. We have shown in detail how UML models are formalized by a set of cTLA processes and production rules. To conduct the performance evaluation of a distributed system, the UML model is transformed into analytic model SRN. We have specified an automated model transformation process to generate SRN ...

A distributed system is a complex system. Developing complex systems is a demanding task when attempting to achieve functional and non-functional properties such as synchronization, communication, fault tolerance. These properties impose immense complexities on the design, development, and implementation of a distributed system that incur massive effort and cost a large amount of money. Therefore, it is vital to ensure that the system must satisfy the functional and non-functional properties once the system development process is finished. Once a distributed system is developed, it is very difficult, time consuming, and expensive to conduct any modification in its architecture. As a result, the quantitative analysis of a complex distributed system at the early stage of the development process is always an essential and intricate endeavor. To meet the challenge of conducting quantitative analysis at the early stage of the system development process, this thesis introduces an extensiv...

This paper presents an empirical study on hedging long-dated crude oil futures options with forward price models incorporating stochastic interest rates and stochastic volatility. Several hedging schemes are considered including delta, gamma, vega and interest rate hedge. Factor hedging is applied to the proposed multi-dimensional models and the corresponding hedge ratios are estimated by using historical crude oil futures prices, crude oil option prices and Treasury yields. Hedge ratios from stochastic interest rate models consistently improve hedging performance over hedge ratios from deterministic interest rate models, an improvement that becomes more pronounced over periods with high interest rate volatility, such as during the GFC. An interest rate hedge consistently improves hedging beyond delta, gamma and vega hedging, especially when shorter maturity contracts are used to roll the hedge forward. Furthermore, when the market experiences high interest rate volatility and the h...

During the trial of Israel Dammon in 1845, which was widely published in an article entitled, "The Horrors of Millerism," which misunderstood many aspects of home-based Adventist services, a curious hymn was sung by Israel Dammon and others. Recently I found the original tune and discovered variants of the hymn. This paper gathers the facts about this unique hymn
