We modify RTM to create an approximate inverse to the extended Born modeling operator in 2D. The derivation uses asymptotic ray theory and stationary phase principle, but the result applies directly to RTM. The inverse operator differs from the adjoint operator only by application of several explicit velocity-independent filters. This inverse operator, on the one hand, can be used as true ampli...

In this paper we study the linearized inverse problem associated with imaging of reflection seismic data. We introduce an inverse scattering transform derived from reverse time migration (RTM). In the process, the explicit evaluation of the so-called normal operator is avoided, while other differential and pseudodifferential operator factors are introduced. We prove that, under certain conditio...

Two problems are common in agile based software development approaches. First, software requirements change frequently and therefore they are difficult to maintain and document. Second, test case development takes time and effort and thus the testing process is often delayed. To provide solution to these problems, we suggest using Action-Triad method for capturing the software application requi...

Accurate solar irradiance data are not only of particular importance for the assessment of the radiative forcing of the climate system, but also absolutely necessary for an efficient planning and operation of solar energy systems. The recently started European project Heliosat-3 will supply high quality solar radiation data by taking advantage of the enhanced capabilities of the new Meteosat Se...

Resin Transfer Molding (RTM) is a manufacturing process that involves injection of liquid resin into a closed mold cavity containing preset fiber mats and a subsequent curing stage. Mold filling is a crucial stage for quality part productions. In order to automate production and minimize the formation of defects, control of mold filling is needed. In this paper, direct adaptive control strategy...

Seismic reflection can provide precise estimates of subsurface structures. To obtain more information on subsurfaces using the same amount data, we first compared reverse time migration (RTM) images obtained from surface seismic profile (SSP), vertical (VSP), and single well (SWP) data for models that included faults with various dips. When were sufficient, SSP, SWP, VSP surveys suitable identi...

The successful manufacture of thick-sectioned composites is challenging, since the highly exothermic nature of thermoset resins and limited temperature control make it difficult to avoid detrimental thermal and cure gradients within the composite. In order to make quality parts, it has been found experimentally that cure temperatures must be lowered as much as 50% from those suggested for thin ...

a r t i c l e i n f o The present study considers a unionised (nonlinear) duopoly with two different labour market institutions, i.e. efficient bargaining (EB) and right to manage (RTM), to analyse product market stability under quantity competition with trade unions. We show that when the preference of unions towards wages is small, (i) the parametric stability region under RTM is higher than ...
