One popular approach to object design proposes to identify responsibilities from software contracts, apply a number of principles to assign them to objects, and finally construct an object interaction that realizes the contract. This three-step activity is currently a manual process that is time-consuming and error-prone, and is among the most challenging activities in object-oriented developme...

A practical Bridge Management System has been developed by the author, which is referred to as the Japanese Bridge Management System (J-BMS) for existing concrete bridges. This paper introduces a newly developed bridge management system for the prestressed concrete (PC) bridges (J-BMS PC version) which is integrated with the PC bridge rating expert system (PC-BREX). The proposed system is able ...

We present a variety of new imaging and kinematic data for the double–lobed radio galaxy Pictor A. The new optical data include HST continuum and [OIII], emission–line images (at a resolution of 25 – 100 mas) and ground-based imaging and spectroscopy (at a resolution of ∼ 1.5). The ground–based images show Hα filaments and loops which extend to the N and W of the optical core. The radio continu...

Today’s, the transportation facilities such as terminals, street, bridge, etc, represent the major investment in highway network. Every year tremendous resources should be invested to maintain these facilities. Among them, the Bridge Management System (B.M.S.) has been necessitated by large imbalance between extensive bridge repair and maintenance needs and limited available budget. So the main...

High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

The allocation of risks among the contracting parties in a contract is an important decision affecting the project success. Some risks in a project are uncontrollable; these are imposed to a project by external factors. Since contracting parties can neither control nor affect the occurrence of such risks, their allocation to a party would be inequitable. Therefore the cost overrun related to un...

there have been a lot of debates between law authors about formation of valid sale contract to the building while constructing for a long time. after enactment of forward sale act in 1389 forward sale building during construction process accepted. however some facts were not answered clearly when the transferring of ownership will be happened: through official forward sale contract or transferr...
