State of the art formal verification is based on methods and its goal proving given correctness properties. For example, a PSTM scheduler was modeled in CSP order to prove deadlock-freeness starvation-freeness. However, as this paper shows, using solely not sufficient. Therefore, we propose complete trustworthy software, which jointly uses model testing. As an first test previous transaction by...

Time-lapse seismic data acquisition is an essential tool to monitor changes in a reservoir due fluid injection, such as CO 2 injection. By acquiring multiple surveys the exact same location, authors can identify by analyzing difference data. However, analysis be skewed near-surface seasonal velocity variations, inaccuracy, and repeatability parameters, other inevitable noise. The common practic...

A method for displaying prestack seismic data that highlights azimuthal anisotropy is shown. Observations of azimuthal anisotropy in prestack seismic data using this and other methods make it clear that azimuthal anisotropy is observed in all types of seismic data, land, marine and multicomponent and it is widespread, from the shallowest to the deepest reflectors. Consequently, anisotropy must ...
