Improved Sobolev Embedding Theorems for Vector-valued Functions
The aim of this paper is to give an extension of the improved Sobolev
embedding theorem for single-valued functions to the case of vector-valued
functions which is involved with the three-dimensional massless Dirac operator
together with the three- or two-dimensional Weyl--Dirac (or Pauli) operator,
the Cauchy--Riemann operator and also the four-dimensional Euclidian Dirac
operator.Comment: 40 pages. To appear in Funkcialaj Ekvacioj 57 (2014
Network flow of mobile agents enhances the evolution of cooperation
We study the effect of contingent movement on the persistence of cooperation
on complex networks with empty nodes. Each agent plays Prisoner's Dilemma game
with its neighbors and then it either updates the strategy depending on the
payoff difference with neighbors or it moves to another empty node if not
satisfied with its own payoff. If no neighboring node is empty, each agent
stays at the same site. By extensive evolutionary simulations, we show that the
medium density of agents enhances cooperation where the network flow of mobile
agents is also medium. Moreover, if the movements of agents are more frequent
than the strategy updating, cooperation is further promoted. In scale-free
networks, the optimal density for cooperation is lower than other networks
because agents get stuck at hubs. Our study suggests that keeping a smooth
network flow is significant for the persistence of cooperation in ever-changing
societies.Comment: 7 pages, 5 figure
Current Condition of the Japanese Construction Market, Contract Management, and Construction Management Education in Three ASEAN Universities
This paper reports on a basic study on the current condition of the Japanese construction market, the third largest market in the world, and contract management in Japan. It also deals with the current condition of construction management education, which is the basis for contract management in Japan and three ASEAN countries namely, Indonesia, Singapore, and Thailand. The Japanese construction market is introduced in terms of its scale and overseas expansion of leading Japanese construction companies. The characteristics of the Japanese construction market and a survey on Japanese construction management education are introduced. The curriculums of construction management education in three ASEAN universities are surveyed. Finally, by comparing the three ASEAN universities and Japan horizontally and internationally, the current condition of construction management education in civil engineering is obtained. The outcome deepens understanding of access to each construction market and can be the first step toward construction business collaboration between Japanese and some ASEAN countries
