Recent Developments in Bulgarian Transport Privatization Policy

Expanding Bulgaria’s political, economic, and cultural cooperation with the countries of Asia is a major priority of the Bulgarian government policy. Transport plays a key role in the implementation of this priority both by providing the necessary conditions for international transit traffic and by meeting the needs of the Bulgarian economy and population. Structural reform in transport to a great extent depends on a sustainable investment policy. At present, prevailing conditions are likely to attract investments, especially to the airports of Sofia and Bourgas. In recent years, the Bulgarian State Railways (“BDZh”) has lagged behind in its development in comparison with the other transport modes in the country and the railways in other European countries. The rehabilitation of the railways is crucial not only for BDZh itself but also for the entire country because the railways are the backbone of the international transport corridors that cross Bulgaria. The management of the Ministry of Transport considers privatization a significant element of the structural reform in the branch. The introduction details how expanding Bulgaria\u27s political, economic, and cultural cooperation with the countries of Asia is a major priority of the Bulgarian government policy, and how transport plays a key role in the implementation of this priority both by providing the necessary conditions for international transit traffic and by meeting the needs of the Bulgarian economy and population. Part I addresses how structural reform in transport to a great extent depends on a sustainable investment policy. Part II focuses on the opportunities which investment in airports present. Part III addresses the advantages of investment in ports. Part IV focusses on Bulgarian State Railways. Finally, Part V addresses how privatization intersects with each of these transport sectors and is a significant element of structural reform

The intestine as a diagnostic character in identifying certain clupeoids (Engraulididae, Clupeidae, Dussumieriidae) and as a morphometric character for comparing anchoveta (Centengraulis mysticetus) populations

ENGLISH: The several species of clupeoid fishes used as baitfish in the Eastern Pacific tuna fishery are, in some cases, sufficiently similar to make identification difficult. During a review of the anatomy of the intestine of clupeoid fishes it was observed that the morphology of the intestine is sometimes a useful character in the identification of systematic groups. The genera at least can be distinguished by means of the topographical anatomy of the intestines. This also may be a useful character because it is often found that a species occurs in the same area as another species that may be confused with it on external inspection, although it belongs to a different genus. SPANISH: La gran similitud morfológica de varias especies del órden Clupeoidea usadas como cebo en la pesquería de atún del Pacifíco Oriental, hace que su identificación sea en algunos casos difícil. Al realizar una revisión anatómica del intestino de los peces clupeoides, se observó que la morfología del mismo es a veces un carácter útil para la identificación de los diversos grupos sistemáticos. Al menos los géneros pueden ser distinguidos por medio de la anatomía topográfica de los intestinos. Esto también puede ser un carácter útil, puesto que a menudo dos especies pertenecientes a géneros diferentes y que ocupen la misma área, pueden ser confundidos si nos basamos solamente en la morfología externa.

Classifying crossed product C*-algebras

I combine recent results in the structure theory of nuclear C*-algebras and in topological dynamics to classify certain types of crossed products in terms of their Elliott invariants. In particular, transformation group C*-algebras associated to free minimal Z^d-actions on the Cantor set with compact space of ergodic measures are classified by their ordered K-theory. In fact, the respective statement holds for finite dimensional compact metrizable spaces, provided that projections of the crossed products separate tracial states. Moreover, C*-algebras associated to certain minimal homeomorphisms of odd dimensional spheres are only determined by their spaces of invariant Borel probability measures (without a condition on the space of ergodic measures). Finally, I show that for a large collection of classifiable C*-algebras, crossed products by Z^d-actions are generically again classifiable.Comment: some corrections and explanations added; 22 pages; to appear in American Journal of Mathematic

Balancing expression dags for more efficient lazy adaptive evaluation

Arithmetic expression dags are widely applied in robust geometric computing. In this paper we restructure expression dags by balancing consecutive additions or multiplications. We predict an asymptotic improvement in running time and experimentally confirm the theoretical results. Finally, we discuss some pitfalls of the approach resulting from changes in evaluation order.Comment: MACIS 2017 Submissio
