this paper proposes an extension of markov chain model to characterize of geological formations and to make conditioning on any number of well data possible. in this study, lithofacies cycles of the amiran formation at type and pirshamsedin sections are examined by markov method and entropy analysis as well as field observations, and depositional environment has interpreted by proposed ideal se...

Abstract The underpinning problems of deep-water facies still remain unresolved. (1) Tb, Tc, and Td divisions the turbidite model, with traction structures, are an integral part “Bouma Sequence” (Ta, Td, Te). However, deposits thermohaline contour currents, wind-driven bottom deep-marine tidal baroclinic currents (internal waves tides) also develop discrete rippled units, mimicking Tc. (2) appl...

Crowding is the inability to identify an object among flankers in the periphery. It is due to inappropriate incorporation of features from flanking objects in perception of the target. Crowding is characterized by measuring critical spacing, the minimum distance needed between a target and flankers to allow recognition. The existing Bouma law states that, at a given point and direction in the v...

PERCEPTION ON THE ROAD WHEN VISIBILITY IS LOW We should like to pay tribute to the memory of Dr. Pieter Johannes Bouma, born in Amsterdam on 14th April 1908, who died at Eindhoven on 19th January 1947. Bouma was connected with the Philips Laboratory in Eindhoven as an assistant from 1928 until 1930 and as a research physicist from 1933 until his death. From 1930 until1933 he studied at Utrecht,...

While French degree words have been assigned several syntactic categories, we show that they are rather highy ‘polymorphic’ adverbs (they occur in all syntactic domains), which select the expression they modify on a purely semantic basis. Like French adverbs in general, they occur both to the left and to the right of the head they modify. Following previous work (a.o. van Noord and Bouma 1994, ...

A graph-unification-based representation language is described that was developed as the grammar formalism for the LILOG research project at IBM Germany. The Stuttgart Unification Formalism (STUF) differs from its predecessors in its higher flexibility and its algebraic structure. It is well suited for the implementation of rather different linguistic approaches, but is currently employed mainl...
