Development Of Decision-Making Algorithm On Efficiency Of Operators And Traffic Controllers Of Air Transport Based On Their Psycho-Physiological Conditions And Productivities R.M. Jafarzade, T.R. Jafarzade By processing the data on the human-operator active performance with respect to their psycho-physiological conditions and productivities in the human-machine systems, we developed the algorithm for the possibilities of further execution of their (operator) duties in the incomplete and unclear initial data. Using fuzzy clustering and the interval fuzzy sets of the second type, and the coordinated assessment of expert opinions on the binary relationship of objects from the class with recommendations on the further implementation of their activities, we obtained the individual assessment of the alternative recommendations for each of the tested objects from the set of objects. The calculation for the experimental data is provided. The proposed approach can be used for the adaptive selection of recommendations on the continuation of duties of air operators and air traffic controllers by taking into account the dynamic of changes of their psycho-physiological states and productivities.

Mirzayev The results of starting pressure change by switching injection direction of working agent from circular annulus to the central part in gas lift wells have been given. The valves are placed on the pipe surface in definite depth under liquid column. As a result of investigation it has been determined that the application of the method in the wells with big depth and high liquid column gives an opportunity to reduce starting pressure. Application of the method in complicated exploitation conditions gives effective results. Comparative Analysis Of Trading Systems Performances With Respect To Transaction Cost (Part 2) E.J. Janahmadov The purpose of this paper is to compare and analyze the performance of trading rules applied to the underlying and derivative products. Three different trading market indictors were chosen from the range of trading rules according to their performance relatively to Dow Jones Industrial Average. On the basis of these technical indicators the automated trading systems were developed and then applied to the underlying instrument such Dow Jones Industrial Average. The performances of trading systems and profit/loss indexes were compared and analyzed. The results are compared with “buy-and-hold” strategy and performance of underlying security. The results of the research intend to show the effect of the transactions costs on the performance of trading systems and optimal could be applied to invest into underlying or derivatives of underlying.

This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.
