It has been widely accepted that there exist investors who adopt momentum strategies in real stock markets. Understanding the momentum behavior is of both academic and practical importance. For this purpose, we propose and study a simple agent-based model of trading incorporating momentum...

Chinese stock markets have experienced an extraordinary bull market since Jan 2006, which attracted global eyes. We investigate the statistical properties of the indices’ log-return r(t) for the bull market (Jan 2006–Oct 2007) and the previous bear market (Jan 2001–Dec 2005). Here we...

Since Frisch’s classical damping oscillator model has failed to explain persistent economic fluctuations very satisfactorily, we suggest a non-classical oscillator model based on Quantum Mechanics, in an attempt to explain such fluctuations in stock markets. This is based on the assumption...

We have studied the multipole polarizability of a graded spherical particle in a nonuniform electric field, in which the conductivity can vary radially inside the particle. The main objective of this work is to access the effects of multipole interactions at small interparticle separations,...

We present a stochastic model for evaluating distributed generation investment under uncertainty. The objective is to estimate the break-even price and its probability distribution. The model is developed based on the probabilistic influence diagram technique and the main uncertain variables are...

We present the findings of a literature survey on decision analysis in energy and environmental modeling. Surveyed studies are classified according to the decision analysis technique used and by application area. It has been found that decision making under uncertainty is the most important...
