Seminar: A Stochastic R&D Competition with Lower and Upper Bounds

Date / Time: 21.5.2013 / 15.30

Place: IAM – S209 (Seminar Room)

Abstract

Abstract. In this work, we analyze the competition between several firms to complete a project. Each firm decides how much it invests in the project while adhering to firm-specific lower and upper investment bounds. The completion time of the project by a firm has exponential distribution with rate that depends linearly on the investment of the firm. The firm that completes the project first collects all the revenues associated with it and the remaining firms earn nothing. We show that there exists a unique Nash equilibrium and a unique globally optimal solution, in non-degenerate cases. We do this by deriving explicit representations parametric in the interest rate. This enables us to develop a computationally efficient method to solve the problem. We conclude by analyzing the effects of marginal changes in lower and upper bounds.

Seminar: Mathematical Models for Earthquake Simulations: Forward and Inverse Model Applications on North Anatolian
Fault Zone

Date / Time: 26.2.2012 / 15.30

Abstract

Estimation of ground motions of large earthquakes in urban regions is
essential in terms of reliable seismic hazard estimation, earthquake resistant
building design, and disaster mitigation. In regions of sparse seismic networks,
ground motion simulations are required to assess past and potential ground
motions. In this talk, I will briefly mention some of the existing theoretical
and field methods for the forward and inverse ground motion simulations for
large earthquakes with particular focus on our recent work in the Northwestern
Turkey. I will as well discuss the limitations of these models and possible
remedies for future applications.
