One of the major questions in the theory of Toeplitz operators on the Bergman space over the unit disk D in the complex plane C is a complete description of the commutant of a given Toeplitz operator, that is the set of all Toeplitz operators that commute with it. In [4], the first author obtained a complete description of the commutant of Toeplitz operator T with any quasihomogeneous symbol φ(...

In low-pressure discharges, where the electron mean free path is larger or comparable with the discharge length, the electron dynamics is essentially nonlocal. Moreover, the electron energy distribution function (EEDF) deviates considerably from a Maxwellian. Therefore, an accurate kinetic description of the low-pressure discharges requires knowledge of the nonlocal conductivity operator and ca...

This paper deals with a scene recognition system in a robotics context. The general problem is to match images with a priori de­ scriptions. A typical mission would consist in identifying an object in an installation with a vision system situated at the end of a manip­ ulator and with a human operator provided description, formulated in a pseudo-natural language, and possibly redundant. The ori...

Feature structures are informational elements that have been used in several linguistic theories and in computational systems for natural-language processing. A logicaJ calculus has been developed and used as a description language for feature structures. In the present work, a framework in three-valued logic is suggested for defining the semantics of a feature structure description language, a...

We present RAT-OWL, a software system for reasoning about typicality in preferential Description Logics. It is implemented in the form of a Protégé 4.3 Plugin and it allows the user to reason in a nonmonotonic extension of Description Logics based on the notion of “rational closure”. This logic extends standard Description Logics in order to express “typical” properties, that can be directly sp...

In this work we present RAT-OWL, a Protégé 4.3 Plugin for reasoning about typicality in preferential Description Logics. RAT-OWL allows the user to reason in a nonmonotonic extension of Description Logics based on the notion of “rational closure”. This logic extends standard Description Logics in order to express “typical” properties, that can be directly specified by means of a typicality oper...

We introduce a new concept of general $G$-$eta$-monotone operator generalizing the general $(H,eta)$-monotone operator cite{arvar2, arvar1}, general $H-$ monotone operator cite{xiahuang} in Banach spaces, and also generalizing $G$-$eta$-monotone operator cite{zhang}, $(A, eta)$-monotone operator cite{verma2}, $A$-monotone operator cite{verma0}, $(H, eta)$-monotone operator cite{fanghuang}...

In dynamic simulation of complete wheel loaders, one interesting aspect, specific for the working task, is the momentary power distribution between drive train and hydraulics, which is balanced by the operator. This paper presents the initial results to a simulation model of a human operator. Rather than letting the operator model follow a pre-defined path with control inputs at given points, i...

Recent work has shown that for finding static Bayesian network structures, an Evolutionary Programming (EP) approach that exploits the description length of single links is better suited than a standard Genetic Algorithm (GA). We extend this work to find good dynamic Bayesian network structures that can have large time lags. We do this through the use of a new representation of dynamic Bayesian...
