The Stability

In recent two decades, more and more marine structures, such as breakwater, bridge, oil platform and turbines are constructed on seabed in offshore area. The stability of these marine structures after construction under the environmental loading is the main concern for the coastal engineers involved in the design work. Generally, there are two types of environmental loading in offshore area. One of them is the ocean wave and the other is the possible earthquake. Ocean wave is the conventional loading for all marine structures. However, little attention and investigation has been paid for the second type of environmental loading-seismic wave and conducted in the previous literatures. In this study, an experimental study was carried out for the stability of caisson type breakwater located on a firm bed condition under regular harmonic seismic wave. The results obtained from this experimental study were also used for the verification of the newly modified sliding block analysis model.

Methods Of Control

A simulation apparatus for the experimental study of the methods of control of batch reactors is devised. In this apparatus, the production of heat by an exothermic reaction is replaced by electric heating controlled by a computer in a closed loop; the reactor is cooled with an external cooler whose dynamic properties can be varied while keeping the heat exchange area constant. The effect of the cooler geometry on its dynamic properties is investigated and the effect of the cooler inertia on the stability and safety of the on-off temperature control in the unstable pseudostationary state is examined.

The Stability

The predictive value and the reliability of evaluations made in immersive projection environments are limited when compared to the real world. As in other applications of numerical simulations, the acceptance of such techniques does not only depend on the stability of the methods, but also on the quality and credibility of the results obtained. In this paper, we investigate the predictive value of virtual reality and virtual environments when used for engineering assessment tasks. We examine the ergonomics evaluation of a vehicle interior, which is a complex activity relying heavily on know-how gained from personal experience, and compare performance in a VE with performance in the real world. If one assumes that within complex engineering processes certain types of work will be performed by more or less the same personnel, one can infer that a fairly consistent base of experience-based knowledge exists. Under such premises and if evaluations are conducted as comparisons within the VE, we believe that the reliability of the assessments is suitable for conceptual design work. Despite a number of unanswered questions at this time we believe this study leads to a better understanding of what determines the reliability of results obtained in virtual environments, thus making it useful for optimizing virtual prototyping processes and better utilization of the potential of VR and VEs in company work processes.
