This paper presents a new model based document image segmentation scheme that uses XML-DTDs (eXtensible Mark-up Language-Document Type Definition). Given a document image, the algorithm has the ability to select the appropriate model. A new wavelet based tool has been designed for distinguishing text from non-text regions and characterization of font sizes. Our model based analysis scheme makes...

Branching bisimulation with explicit divergence, introduced by van Glabbeek and Weijland, is an important relation between processes. It is the weakest equivalence relation which is a branching bisimulation and at the same time divergence preserving. Like branching bisimulation, it has two major characterizations in the literature: a relational characterization and a coloured trace characteriza...

We describe the design, implementation and usage of Rubicon, a tool for the characterization of I/O workloads. Rubicon provides a rich set of operations on I/O traces, and was designed to be easily extended through the addition of new analysis functions and reporting methods. The design of Rubicon makes it simple to adapt to multiple types of workload characterization, and allows the user to fo...

dna barcoding is a new term introduced in to scientific literatures by hebert and coworkers almost a decade ago. the concept of barcoding alone is well-known to the public: a series of black bars printed on many commercial products (universal product code), which are used to distinguish different products. advances made in molecular biology and molecular techniques late 20th century e.g. sequen...

Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without ...

Micro X-ray fluorescence ~MXRF! offers the analyst a new approach to materials characterization. The range of applications is expanding rapidly. Single point analysis has been demonstrated for nanoliter volumes with detection limits at the 0.5 ng level. MXRF can be used as an element specific detector for capillary electrophoresis. Elemental imaging applications include analysis of sample corro...

A new perspective on the emergence of statistical behavior in chaotic quantum many-body systems is presented, establishing projected ensembles as a relevant tool for characterization information-theoretic properties.
