Efficiency of pattern matching for MOLA model transformation language is analyzed in the paper. A virtual machine and pattern matching procedure based on it is proposed, which takes into account the specific requirements for efficient pattern matching in MOLA. On the basis of a typical MDA example it is shown that the proposed solution is optimal and the conclusions are generalized to typical M...

Ocean sunfish, family Molidae, are enigmatic members of the epipelagic fauna of all tropical and temperate oceans. A study, begun in 1998, initially focused on the population genetics of Mola mola Linnaeus 1758 immediately indicated high levels of genetic divergence in the d-loop and cytochrome b mitochondrial genes. This preliminary effort was expanded to include Masturus lanceolatus Liénard 1...

Evidence is provided from stable isotope analysis that aggregations of small ocean sunfish Mola mola (total length <1 m) feed broadly within coastal food webs and their classification as obligate predators of gelatinous zooplankton requires revision.

Textual models in MDD typically are generated in their concrete syntax using a template based language. On the contrary, graphical models as a rule are generated in abstract syntax and then visualized, which is not very efficient for complicated languages. The paper discusses a case of template based generation of graphical models in a concrete syntax. We apply this approach to generation of pr...

Launched in 1996, Mars Global Surveyor (MGS) carries two types of mapping equipments: Mars Orbiter Laser Altimeter (MOLA) and Mar Orbiter Camera (MOC). MOLA collects accurate laser altimetry data over the Mars surface, while MOC acquires high resolution images. In the process of MOLA registration to MOC images, a certain systematic shift was reported in previous studies. This shift may possibly...

The design, calibration, and performance of the Mars Orbiter Laser Altimeter (MOLA) receiver are described. The MOLA measurements include the range to the surface, which is determined by the laser-pulse time of flight; the height variability within the footprint determined by the laser echo pulse width; and the apparent surface reflectivity determined by the ratio of the echo to transmitted pul...
