Structural Deterioration and Monitoring

Online monitoring and visualisation of database structural deterioration

Structural deterioration of database is caused by updates of the database and can degrade performance seriously. Database reorganisation, which removes structural deterioration by relocating data in the secondary storage, is an administrator’s headache; it is difficult to schedule reorganisation efficiently to keep acceptable performance because conventional database systems lack crucial monito...

Structural Deterioration in Produce: Phospholipase D, Membrane Deterioration, and Senescence

Ripening and senescence are the ultimate phases in the developmental events of fruits that result in the expression of the quality characteristics inherent to the fruit. Although it is difficult to demarcate a dividing point between ripening and senescence, the former can be designated as the quality-developing phase, whereas the latter predominantly involves the loss of quality. Degradation of...

Structural Control and Health Monitoring

Control forces in semi-active control systems are constrained by the dynamics of actuators that regulate energy transmission through variable damping and/or stiffness mechanisms. The potential benefit of the development and implementation of new semi-active control devices and applications can be determined by optimizing the controlled performance subject to the constraints of the dynamics of t...

Structural Control and Health Monitoring

A unique shape memory alloy (SMA) restrainer cable is developed and tested to evaluate its effectiveness in limiting the hinge opening in bridges. The SMA cables, connected at the deck–abutment interface, are tested on a four-span, one-quarter scale, concrete slab bridge. The bridge is subjected to a suite of ground motion to assess the performance of the SMAs under different magnitudes of load...
