In this research, using the Modified Compression Field Theory (MCFT), a new model is proposed to predict the behavior of reinforced concrete coupling beams. The model is able to consider the effects of shear and axial forces and bending moment, simultaneously. The proposed model includes a nonlinear shear spring, an axial spring and some nonlinear springs for considering bending deformations. I...

We developed a visual system generator called “Rainbow” which can handle layout constraints. The system can interactively layout figures while parsing them and make the parsed figures more understandable. Rainbow can deal with “soft layout constraints.” Soft layout constraints automatically layout entire figures by using graph drawing algorithms. Soft layout constraints are more flexible than c...

In this study, it is theorized that party websites play a distinctive role in two regards: (i) they function as a pluralistic civic forum by facilitating the voice of oppositional challengers and increasing the visibility of minor and fringe parties, so that attentive citizens can learn more about the range of electoral choices; (ii) in addition, party websites function as a channel for politic...

During human and animal locomotion, the dynamics of the body can be represented with the help of simplified biomechanical models, such as the spring-mass model (often described as spring-loaded inverted pendulum, SLIP model). In this model, it is assumed that the force generated by each limb resembles that of a linear spring. Furthermore, it is assumed that force generated by the leg mainly act...

A number of studies and researches have been conducted on Virtual Surgery Planning. More specifically, topics on interactive virtual surgery using haptic device have been discussed in [1][2] and so on. Due to the nature of high demand in physical accuracy, many researchers adapted Finite Element Method(FEM) for the simulation. In this paper, I propose simplified massspring model for the interac...

This paper presents a new method for real-time modelling soft tissue deformation. It improves the traditional mass-spring model with conical springs to deal with nonlinear mechanical behaviours of soft tissues. A conical spring model is developed to predict soft tissue deformation with reference to deformation patterns. The model parameters are formulated according to tissue deformation pattern...
