A weighted sum of spatial gradients (WSSG) control metric for use in active structural acoustic control of finite ribbed plates was developed and compared to volume velocity. A finite element model was used to obtain the displacement field on the plate, and a finite difference derivative approach to obtaining the terms in WSSG was used. Previous results of ASAC on finite ribbed plates are minim...

Registry versus clinical trial The main goal of pregnancy registries includes the rapid identification of signals of increased teratogenic risk as quickly as possible, which is especially important for newly available anti epileptic drugs (AEDs) [1–3]. When the association between an increased risk and an AED is found in a registry, the cause can be further explored in a case–control study or a...

Vanags T, Budimlic M, Herbert E, Montgomery MM, Vickers T. Showercap Mindmap: a spatial activity for learning physiology terminology and location. Adv Physiol Educ 36: 125–130, 2012; doi:10.1152/advan.00095.2011.—Students struggle with the volume and complexity of physiology terminology. We compared first-year undergraduate psychology students’ learning of physiological terms using two teaching...

We have developed a system which analyses how users behave when using a geospatial interface. Mouse movements and operations performed by users are assessed as a proxy to implicitly determine their interests, and personalise their spatial content accordingly. Users’ interface behaviour can be visualised to gain a better understanding of the correlation between their actions, intentions and inte...

1 Abstract-A new parameter was recently developed by Jeffery M. Fisher (M.S.) for use in Active Structural Acoustic Control (ASAC) which showed potential for achieving better sound radiation reduction than current parameters. This parameter, known as “Vcomp,” uses spatial derivatives to approximate radiation mode shapes and was shown analytically to produce results comparable to control of radi...
