Abstract This article presents regression equations to estimate container ship design characteristics based on the most up-to-date data and deadweight capacity, the number of containers and their combination at the preliminary design stage. These design formulas could have application for the estimation of key container ship characteristics such as: main ship dimensions, geometric parameters, main engine total power, ship velocity, final price and others. Regression equations were performed on the basis of IHS Maritime & Trade main container ship data built from 2005-2015. All equations presented in this paper could have practical application at the preliminary design stage and increase ship design theory development.

Temperature Field Model

The random properties on buried pipe of ground-source heat pump (GSHP) is analyzed, the equation of Kelvin one-dimensional line source of heat transfer model is discussed. The model randomness is analyzed also, and the GSHP buried pipe to random excess temperature field, space-time statistics and the correlation of features are studied. The engineering example shows that heat transfer in buried pipe has relationship with the distance from the pipe center and run time of the system, and also the heat transfer between buried pipes can not be ignored. The method in this paper has great significance for improving the reliability design theory and reducing the construction cost of GSHP buried pipe in this paper.

Is Design

Virtual communities are complex and evolving socio-technical systems. The design of community information systems requires much theoretical research to solve design problems. A design theory is a prescriptive theory which helps optimize design methods. Community IS design theory is still very young and fragmented, however. In the design theory development process, a mix of theory components is used to solve novel problems or existing problems more effectively and efficiently. We present a meta-model of IS development which focuses on the role of theory in IS design. We show how simulation via system dynamics could play an important role in a more systematic development of design theory for community information systems.
