Generalized Monotonicity Analysis

Complex economic models often lack the structure for the application of standard techniques in monotone comparative statics. Generalized monotonicity analysis (GMA) extends the available methods in several directions. First, it provides a way of finding pa ...

Universal monotonicity of eigenvalue moments and sharp Lieb-Thirring inequalities

Joachim Stubbe

We show that phase space bounds on the eigenvalues of Schrodinger operators can be derived from universal bounds recently obtained by E. M. Harrell and the author via a monotonicity property with respect to coupling constants. In particular, we provide a n ...

Analysis of two stationary magnetohydrodynamics systems of equations including Joule heating

Rafael Vazquez Hernandez

We study the coupling of the equations of steady-state magnetohydrodynamics (MHD) with the heat equation when the buoyancy effects due to temperature differences in the flow as well as Joule effect and viscous heating are (all) taken into account. Two mode ...

Partitioning Datasets Based on Equalities Among Parameters

Giancarlo Ferrari Trecate

When a phenomenon is described by a parametric model and multiple datasets are available, a key problem in statistics is to discover which datasets are characterized by the same parameter values. Equivalently, one is interested in partitioning the family o ...

A New Fast Training Algorithm of the WTM Kohonen Neural Network Implemented for Classification of Biomedical Signals

Rafal Tomasz Dlugosz

A new optimized algorithm for the learning process suitable for hardware implemented Winner Takes Most Kohonen Neural Network (KNN) has been proposed in the paper. In networks of this type a neighborhood mechanism is used to improve the convergence propert ...

Risk Aversion and Equilibrium Optimal Portfolios in Large Markets

Semyon Malamud

We consider a simple continuous-time economy, populated by a large number of agents, more risk averse than the log agent, with hetero- geneous risk aversion densely covering an interval. Even though the dividend is a geometric Brownian motion, the equilibr ...

Model Predictive Control Schemes for Consensus in Multi-Agent Systems with Single- and Double-Integrator Dynamics

Giancarlo Ferrari Trecate

In this paper we address the problem of driving a group of agents towards a consensus point when the agents have a discrete-time single- or double-integrator dynamics and the communication network is time-varying. We propose decentralized Model Predictive ...

Jamming in granular media

Michel Tsukahara

This thesis studies the phenomenon of jamming in granular media, such as when a salt shaker gets clogged. We use modern instrumentation, like X-ray synchrotron tomography, to look inside real jamming experiments. High performance computers allow simulating ...

Weighted A* search - unifying view and application

The A* algorithm is a well-known heuristic best-first search method. Several performance-accelerated extensions of the exact A* approach are known. Interesting examples are approximate algorithms where the heuristic function used is inflated by a weight (o ...
