We study the gas-water transient imbibition and drainage processes in two-dimensional nanoporous media using our recently developed Lattice Boltzmann model (LBM). To describe the microscopic molecular interactions, the model employs a pseudopotential that correlates the local density and...

We develop a portfolio-choice model to investigate the relationship between firm's capital adequacy and risk-taking under a risk-based (or non-risk-based) capital regulation and examine how a regulatory reform influences this relationship. The model predicts that either all financial...

In this paper, the authors consider the planning problem for a system represented as a set of interacting agents evolving along time according to explicit timing constraints. Given a goal, the planning problem is to find the sequence of actions such that the system reaches the goal state in a...

Studying the function call graphs in complex software can provide significant insights into the software evolution process. We found node in- and out-degree distributions asymmetric in the call graphs of 223 versions of Linux kernel modules (V1.1.0 to V2.4.35). Nodes newly introduced in these...

The application of distributed variable speed pumps (DVSP) in the district heating (DH) network has been considered as a technology improvement that has a potential of saving energy, compared to the conventional central circulating pump (CCCP) DH system. A hydraulic model was developed to...
