A central question in arrangement theory is to determine whether the characteristic polynomial ∆q of the algebraic monodromy acting on the homology group HqpFpAq,Cq of the Milnor fiber of a complex hyperplane arrangement A is determined by the intersection lattice LpAq. Under simple combinatorial conditions, we show that the multiplicities of the factors of ∆1 corresponding to certain eigenvalu...

The Electrochemical Noise Method (ENM) has particular attractions because of its nonintrusive nature, quickness in gathering data and ease of interpretation. The electrode arrangement for the standard (“Bridge”) method of conducting ENM requires two separate working electrodes e.g. two painted Q panels and a reference electrode. Although satisfactory for laboratory use, it is not so suitable fo...

Arrangements of (pseudo-)circles have already been studied in connection with algorithms in computational geometry. Thereby information on the numbers v k of intersection points contained in k circles seems to be particularly interesting. On each circle, there is an induced arrangement of arcs. This is why we begin by studying arrangements of arcs, and we arrive at a complete characterization o...

As a basis for information recovery in open dynamic microeconomic systems, we emphasize the connection between adaptive intelligent behavior, causal entropy maximization and self-organized equilibrium seeking behavior. This entropy-based causal adaptive behavior framework permits the use of information-theoretic methods as a solution basis for the resulting pure and stochastic inverse economic-...

The paper presents a model of designing of machine layout in flexible manufacturing system (FMS). Evolutionary computation, particularly genetic algorithms (GAs) proved to be successful in search of optimal solution for this type of problems. To achieve high productivity in a flexible manufacturing system (FMS), an efficient layout arrangement and material flow path design are important due to ...

This paper describes the long-distance reproduction of professional-level piano performance by transmission of redundant indexed UDP packets containing MIDI data over the Internet. Our project was developed with the express intent of enabling remote instruction of piano Master Classes where highly accurate and subtle musical gestures must be reproduced. With MIDI grand pianos on both ends of a ...

Scope and Purlmse---An effective tool management is a major requirement for the implementation of a flexible manufacturing system (FMS), hence the computer numerical control (CNC) machine tools. A new solution methodology to the tool management problem is proposed in connection with the tool magazine arrangement and operations sequencing decisions, where there can be alternative tools for each ...

The title compound, [Ti(C(5)H(5))(2)(C(16)H(11)NO(5))]·H(2)O, exhibits a titanocene unit coordinated to a styrene-substituted pyridine-2,6-dicarboxyl-ate ligand synthesized for use as a monomer for polymerization or copolymerization yielding metallocene-containing polymers. The compound crystallized as a monohydrate and the solvent water mol-ecule forms strong O-H⋯O hydrogen bonds with the carb...

The left regular band structure on a hyperplane arrangement and its representation theory provide an important connection between semigroup theory and algebraic combinatorics. A finite semigroup embeds in a real hyperplane face monoid if and only if it is in the quasivariety generated by the monoid obtained by adjoining an identity to the two-element left zero semigroup. We prove that this quas...
