Indifference Pricing for Power Utilities

Semyon Malamud

We study utility indiﬀerence pricing of claim streams with intertem- poral consumption and power (CRRA) utilities. We derive explicit for- mulas for the derivatives of the utility indiﬀerence price with respect to claims and wealth. The simple structure of ...

Estimation of travel time on urban networks with midlink sources and sinks

André-Gilles Dumont, Edward Chung, Ashish Bhaskar

This paper presents a methodology for estimation of average travel time on signalized urban networks by integrating cumulative plots and probe data. This integration aims to reduce the relative deviations in the cumulative plots due to midlink sources and ...

Relative Extinction of Heterogeneous Agents

Semyon Malamud

In all the existing literature on survival in heterogeneous economies, the rate at which an agent vanishes in the long run relative to another agent can be characterized by the diﬀerence of the so-called survival indices, where each survival index only dep ...

Multi-objective thermoeconomic optimisation of the design of heliostat field of solar tower power plants

Daniel Favrat, Xavier Pelet

Solar thermal power plants have a large potential, particularly in the sun belt countries around the world. The objectives of this study are to identify the heliostat fields for solar tower plants with the lowest specific energy cost and to investigate the ...

Design and optimization of district energy systems

François Maréchal, Daniel Favrat, Céline Weber

The reduction of CO2 emissions is a challenge for the coming decade, especially with the implementation of the Kyoto protocol. Since energy services (mainly heating and cooling of buildings) contribute to over 40% of the final energy consumption in a count ...

Design of heliostat fields using a multi-objective evolutionary algorithm

Daniel Favrat, Xavier Pelet

The paper discusses the interest of the multi-objective optimization approaches for the design of complex energy systems and the basics of the original evolutionary algorithm used. The specific problems linked to the design of the concentrators of solar to ...

An Exact Method for Computing the Area Moments of Wavelet and Spline Curves

Michaël Unser, Thierry Blu, Mathews Jacob

We present a method for the exact computation of the moments of a region bounded by a curve represented by a scaling function or wavelet basis. Using Green's Theorem, we show that the computation of the area moments is equivalent to applying a suitable mul ...
