It takes long time and huge amount of money to construct inter-city railway network. Careful demand forecasting and rational service planning are therefore required. However, long ranged demand forecasting is always facing to unintended change of regional population or change of the service...

Inter-city distribution network structure is considered as one of which determine the quantity of economic activities in each city. In the field of operations research, several types of optimal facility location problem and algorithms for them have been proposed. Such problems typically minimize...

The contributions in this volume extend our understanding about the different ways distance impacts the knowledge conversion process. Knowledge itself is a raw input into the innovation process which can then transform it into an economically useful output such as prototypes, patents, licences...

Multimodal policy between railway and airlines is of importance in providing seamless transportation service to inter-regional passengers. However, it is difficult to make coordination among the railway and airline service suppliers, especially when they are fiercely competing for the share in...

In 1990's, Japan?s domestic transportation and telecommunication service had been improved, and concurrently the knowledge-intensive business, which requires the intensive communication, becomes much important in economic activities. Improvement in communication technology would influence in two...

For interface-tracking simulation of two-phase flows with a high density ratio, we propose a computational method, NS–PFM, combining Navier–Stokes (NS) equations with phase-field model (PFM) based on the free energy theory. Through the numerical simulations, it was confirmed that (1) the...

In this study, using the lattice Boltzmann method, we simulate soot accumulation in porous media to examine the particle trap in a diesel particulate filter (DPF). The porous media are numerically formed for different inner structure with given porosity. The porous structure similar to the real...

Although diesel engines have an advantage of low fuel consumption in comparison with gasoline engines, several problems must be solved. One of the major concerns is that diesel exhaust gas has more particle matters (PM) including soot, which are suspected to be linked to human carcinogen. As one...

This paper proposes a dynamic multi-regional growth model with free mobility of capital and population. The economic system consists of multiple cities interconnected by high-speed railway systems with each city consisting of one production sector as well as residential land use. The railway...
