Locality and Centrality: The Variety ZG [PDF]
We study the variety ZG of monoids where the elements that belong to a group are central, i.e., commute with all other elements. We show that ZG is local, that is, the semidirect product ZG * D of ZG by definite semigroups is equal to LZG, the variety of

Group Fuzzy Languages and its Generalizations
In fuzzy language theory, every monoid is the syntactic monoid of some fuzzy language. By using this result the properties of fuzzy language can be studied by the algebraic properties of the syntactic monoids. There are so many methods for studying fuzzy

Similarities of Jonsson spectra’s classes
The study of syntactic and semantic properties of a first-order language, generally speaking, for incomplete theories, is one of the urgent problems of mathematical logic.

Piecewise testable tree languages [PDF]
This paper presents a decidable characterization of tree languages that can be defined by a boolean combination of Sigma_1 sentences. This is a tree extension of the Simon theorem, which says that a string language can be defined by a boolean combination

Minimal state automata for detecting a β globin gene mutation
Beta-thalassemia is an autosomal recessive blood disorder characterized by abnormalities in the synthesis of β globin. Together with α globin, it is a subunit of globin protein, called hemoglobin, located inside our red blood cells to deliver oxygen from

An Automata Theoretic Approach to the Zero-One Law for Regular Languages: Algorithmic and Logical Aspects [PDF]
A zero-one language L is a regular language whose asymptotic probability converges to either zero or one. In this case, we say that L obeys the zero-one law.

Efficient Aggregation Processing in the Presence of Duplicately Detected Objects in WSNs
Wireless sensor networks (WSNs) have received increasing attention in the past decades. Owing to an enhancement of MEMS technology, various types of sensors such as motion detectors, infrared radiation detectors, ultrasonic sensors (sonar), and magnetometers can detect the objects within a certain range.

Quantitative Analysis of Software Approximate Correctness
Parameterized bisimulation provides an abstract description of software correctness. In real world situations, however, many software products are approximately correct. To characterize the approximate correctness, we generalize the parameterized bisimulation to numerical version and probabilistic setting.
