OBJECTIVES




Following in the spirit of past conferences at Clermond-Ferrand, France in 1989; Birmingham, England in 1993; Durham, USA in 1997, the purpose of this first meeting in the new century is to communicate continuing developments in research on the micromechanics of granular media.

Understanding the behavior of granular media in terms of micromechanics is of fundamental importance in a number of areas of science and technology - the complexity of the mechanics requires interdisciplinary discussions involving applied mathematicians, statistical physicists, geologists, and chemical/civil/mechanical/agricultural engineers. Practical goals of this activity are improvements in industrial production, process performance, construction design, and so on.

The topics discussed in this meeting range from quasi-static problems to dynamic problems, and are divided into 15 groups: packing geometry, cohesion/cracking, measurement system, wave propagation, quasi-static modeling, quasi-static behavior, submerged behavior, localized deformation, externally disturbed behavior, shear flow, vertical flow, surface flow, vibrated flow, mixed flow and viscous flow/crushing. Each group contains theoretical, experimental and computational approaches by researchers with different backgrounds; such combination will provide new insights not only into the respective sub field but also into other relevant fields. I am convinced that this meeting will be of great benefit to every participant.

I am grateful for financial support provided by the Japan Society for the Promotion of Science, the Japanese Geotechnical Society, Hosokawa Powder Technology Foundation and the Kajima Foundation. I am also grateful to the Executive Committee and the Scientific Committee for their kind help in organizing this meeting. Finally, I would like to thank all the authors for their contibution to the Proceedings and wish all of you an enjoyable and stimulating meeting.

How to reach the New World Hotel in Sendai



Sendai is located 350 km north of Tokyo on the Pacific Coast of Japan. As the number of international flights to Sendai is limited, most visitors from abroad usually travel to Sendai by train, after arriving at Tokyo/Narita International Airport. Domestic flights from major airports, including Osaka/Kansai, Osaka/Itami, Nagoya and Fukuoka, are also available. However, there are no flights from Tokyo. This is because the Shinkansen, (the Bullet Train), is so efficient, that airlines can not compete.
 

Traveling to Sendai by Train via Narita Airport

To travel to Sendai by train, you have to transfer at Tokyo. Narita Express takes you from Narita Airport to Tokyo in about one hour and Tohoku Shinkansen, (Yamabiko), from Tokyo to Sendai in about two hours. You can purchase all the necessary tickets to Sendai at the green ticket counter, (JR Counter), at Narita Airport. Narita Express leaves once or twice an hour from Narita Airport and all the seats are reserved seats. The regular fare from Narita Airport to Sendai is approximately 13,500 yen.
 

Traveling from Sendai Airport

Visitors arriving at Sendai Airport are advised to travel first to Sendai Station by Airport Shuttle Bus. It will take about 40 minutes. The fare is 910 yen. You may use a taxi from the airport directly to the New World Hotel. However, it is very expensive (about 10,000 yen).
 
 






Traveling from Sendai Station to the New World Hotel

Shinkansen platforms in Sendai Station are on the 4th floor. The main exit of Sendai Station is the west exit, in front of which pedestrian's decks are spread on the second level. A taxi pool and bus terminals, including Airport Shuttle Terminal, are located under the decks. You should exit the station at the ground level. To travel from Sendai Station to the New World Hotel, you may take either a hotel shuttle bus or a taxi. The drive usually takes about 30 minutes. The hotel is located in the suburbs, near a huge white statue taller than the hotel with13 story floors.

1) Hotel Shuttle Bus (Free): The shuttle bus stops at a parking lot just in front of West Exit 13 on the ground level. The bus departs every day at 12:30, 17:00, 19:00 and 21:30. On Sunday May 20, other special bus services will be available hourly from 13:00 to 18:00. A sign, "Powders & Grains 2001", will be attached to the bus.

2) Taxi: You can take a taxi just in front of West Exit 12, 13 on the ground level. The fare from Sendai Station to the New World Hotel is about 3,000 Yen. In Japan, you need not tip taxi drivers.
