AN INTEGRATED APPROACH IN THE STUDY OF THE EVOLUTION OF THE STABILISATION POLICY OF THE EUROPEAN UNION
Studying the evolution of European Union's stabilisation policy is a difficult task that requires certain focusing. In a broad sense, stabilisation policy can be defined as a set of measures taken by the government and implemented by certain bodies and mechanisms to overcome problems of the economy or to restore its equilibrium. Of course, processes ongoing at global, regional, and national levels in the economic system should also be taken into account in determining the instruments of the stabilisation policy.
For the European Union in particular, the stabilisation instruments in its development are expressed in changes both in the strategic and in the structural and the institutional aspects and the evolution of the stabilisation policy can
be characterized as distinct periods of development
Supersolid phase of hardcore bosons on triangular lattice
We establish the nature of the supersolid phase observed for hardcore bosons
on the triangular lattice near half-integer filling factor, and study the phase
diagram of the system at finite temperature. We find that the solid order is
always of the (2m,-m',-m') with m changing discontinuously from positive to
negative values at half-filling, contrary to predictions of other phases, based
on an analogy with the properties of Ising spins in transverse magnetic field.
At finite temperature we find two intersecting second-order transition lines,
one in the 3-state Potts universality class and the other of the
Kosterlitz-Thouless type
Isospin dependence of mass-distribution shape of fission fragments of Hg isotopes
Using an improved scission-point model, the mass distributions are calculated for induced fission of even Hg isotopes with mass numbers A=174 to 196. With increasing A of a fissioning AHg nucleus the mass distribution evolves from symmetric for 174Hg, to asymmetric for isotopes close to 180Hg, and back to more symmetric for 192,194,196Hg. In the fissioning Hg isotopes their excitation energy weakly influences the shape of the mass distribution. In 180,184Hg, the mass distributions of fission fragments remain asymmetric even at high excitation energies
Hausdorff distances for searching in binary text images
Hausdorff distance (HD) seems the most efficient instrument
for measuring how far two compact non-empty subsets of a metric space are from each other. This paper considers the possibilities provided by HD and some of its modifications used recently by many authors for resemblance between binary text images. Summarizing part of the existing word image matching methods, relied on HD, we investigate a new similar parameterized method which contains almost all of them as particular cases. Numerical experiments for searching words in binary text images are carried out with
333 pages of old Bulgarian typewritten text, 200 printed pages of Bulgarian Chrestomathy from year 1884, and 200 handwritten pages of Slavonic manuscript from year 1574. They outline how the parameters must be set in order
to use the advantages of the proposed method for the purposes of word matching in scanned document images
Text Search in Document Images Based on Hausdorff Distance Measures
The Hausdorff type distances between the sets of points on the plane are the commonly used similarity measures for binary images. In this work we present several such measures in a unified manner and introduce a new, naturally arisen variant of Hausdorff distance. The matching performance of all similarity measures is compared by computer experiments, using real word images from a scanned book
Some variants of Hausdorff distance for word matching
Several recently proposed modifications of Hausdorff distance (HD) are examined with respect to word image matching for bad quality typewritten Bulgarian text. The main idea of these approaches presumes that omission of the extreme distances between the points of the compared images eliminates the noise (to some extent) and the algorithms become more robust. A few robust HD measures, namely, censored HD, LTS-HD, and
a new binary image comparison method that uses a windowed Hausdorff distance, lie in the base of the computer
experiments carried out using 54 pages of typewritten text
Hausdorff Approximation of Functions Different from Zero at One Point - Implementation in Programming Environment Mathematica
ACM Computing Classification System (1998): G.1.2.Moduli for numerical finding of the polynomial of the best Hausdorff approximation of the functions which differs from zero at just one point or having one jump and partially constant in programming environment MATHEMATICA are proposed. They are tested for practically important functions and the results are graphically illustrated. These moduli can be used for scientific research as well in teaching process of Approximation theory and its application
Word Image Matching Based on Hausdorff Distances
Hausdorff distance (HD) and its modifications provides
one of the best approaches for matching of binary images.
This paper proposes a formalism generalizing almost
all of these HD based methods. Numerical experiments
for searching words in binary text images are carried
out with old Bulgarian typewritten text, printed Bulgarian
Chrestomathy from 1884 and Slavonic manuscript
