14. Recent Advances in Computational Finance

Abstract

As it stands today, the spectrum of methods, tools, and applications that populate the area of computational finance is literally vast. Distinctively, it is this vast domain that differentiates today's financial decision makers from their counterparts of just a decade ago. Couched within this landscape are a set of increasingly complex resource utilization decisions; decisions that are, today, impacted by a surprising growth in technology that now spans a more globally diverse production and engineering environment. Collectively, firm financial managers, portfolio managers, and enterprise risk managers continue to exhort the computational finance community to formulate effective tools that more descriptively reconcile difficult problems in new product development, risk mitigation, and overall enterprise management. The computational finance community has responded to this call by offering refinements to classic computational methods while also introducing new ones. From continuous optimization to natural and evolutionary computing to time-series econometrics, this edition covers contemporary developments in computational finance. The book examines how interdisciplinary contributions from applied mathematics, statistics, and engineering can be adapted to a problem-solving approach in finance with an emphasis on vexing, but identifiable, real-world problems.

Abstract

The presence of psychological stress and inadequate housing infrastructure can inhibit prosocial migration and mitigate the evolution of an urban city to 'smart' status. In the classical economic sense, promoting a prosocial environment encourages constituents to act "rationally" by maximizing the individual's narrow self-interest. However, when individual agents are stressed and anxious in their environment the question often arises about how an individual will display rationality of choice. This research uses an animal model to experimentally evaluate brain areas that might underlie the hyperanxious profile. The specific aim is to examine how alternate housing environments and biological sex interact to modulate neural markers of anxiety-like behavior in trait anxiety bred Long-Evans rats. The findings obtained from the experimental research on rats is translated to a lexicographic multiobjective decision-model that is consistent with a goal set that includes well-known prosocial migration objectives held by municipal decision-makers. These decision-makers routinely face complex resource allocation problems related to restoration needs of high-rise and high-density urban projects. We find strong evidence that the neural circuitry of rats for the expression of fear, emotions and fear avoidance translate well to the observed behavior of residents of urban projects. This translatability permits us to propose a mixed integer nonlinear goal program as a method for solving the complex socio-economic resource problem of urban project renovation.

21. Investigation of a Combined Heat and Power Fuel Cell System for Small Scale Residential Applications

Abstract

Fuel cell technology is an emerging technology that provides a highly efficient, quit operation, and environmentally friendly energy conversion technology for stationary and mobile applications. Stationary fuel cell applications have received greater attention for their ability to capture the heat rejected, from the production of electricity, for heating applications. This paper evaluates a modeled PEMFC system, and presents the heat and power efficiencies of the system. The method used to evaluate the system is the TRNSYS simulation. TRNSYS models the transient performance of thermal systems by using a modular structure. A model of the PEMFC system is developed to determine the energy required to meet the hourly average electric load of the residence. The model evaluates the amount of heat generated and the amount of heat used for thermal loads of the residence. The electricity for lights, appliances, and space cooling is provided by the PEMFC, the space heating and water heating is provided by the thermal energy generated from the PEMFC, which is stored within two hot water storage tanks. An electric resistance heater and an electric water heater will supplement the space heating and water-heating load not provided by the PEMFC. The results of this research show that a 1.5KW system, with a heat exchanger UA value of 5239 kJ/hr-K, and main storage and hot water tank sizes of 80 and 40 gallons, will provide up to 40% energy savings over conventional systems. The system will provided up to 65% cogeneration efficiencies. The economics of the system show that the price of the PEMFC system with a reformer needs to be priced at $20/cell.
