Markov Arrival

Queueing systems with distinguished arrivals are described on the basis of Markov arrival processes with marked transitions. Customers are distinguished by their types of arrival. Usually, the queues observed by customers of different types are different, especially for queueing systems with bursty arrival processes. We study queueing systems from the points of view of customers of different types. A detailed analysis of the fundamental period, queue lengths and waiting times at the epochs of arrivals is given. The results obtained are the generalizations of the results of the MAP/G/1 queue.

We study the queue GI/M/s with customers of m different types. An arriving customer is of type i with probability pi and the types of different customers are independent. A customer of type i requires a service time which is exponentially distributed with parameter bi. This model is equivalent to the queue GI/Hm/s, where Hm denotes a mixture of m different exponential distributions. We are primarily interested in the distributions of waiting times and queue lengths. Using a probabilistic argument we reduce the problem to the solution of a system of Wiener-Hopf-type equations. This system is solved by a factorization method. Thus we obtain explicit results for the stationary distributions of waiting times and queue lengths.

Queueing Processes

Until recently there has been little systematic work on the second-order properties of queueing processes. The aim of this paper is to study systematically the second-order properties of the queue length processes embedded at departure epochs in the M/G/1 and bulk service M/G/1 queues, and at arrival epochs in the GI/M/1 queue. In the latter case our results extend those of Daley [7], while in the ordinary M/G/1 queue our work parallels Daley's [6] discussion of waiting times in the same system. In the final section we briefly discuss two discrete time queueing systems.

Points Of View

Metallic clusters are interesting from various points of view, e.g. as a mean of spreading expensive catalysts on a support, or following heterogeneous and homogeneous catalytic events. It is also possible to study nucleation and growth mechanisms for crystals with the cluster as known starting point.Gold-clusters containing 55 atoms were manufactured by reducing (C6H5)3PAuCl with B2H6 in benzene. The chemical composition was found to be Au9.2[P(C6H5)3]2Cl. Molecular-weight determination by means of an ultracentrifuge gave the formula Au55[P(C6H5)3]Cl6 A model was proposed from Mössbauer spectra by Schmid et al. with cubic close-packing of the 55 gold atoms in a cubeoctahedron as shown in Fig 1. The cluster is almost completely isolated from the surroundings by the twelve triphenylphosphane groups situated in each corner, and the chlorine atoms on the centre of the 3x3 square surfaces. This gives four groups of gold atoms, depending on the different types of surrounding.

Points Of View

The current article presents some of the theoretical aspects of self-presentation describing different points of view on the issue. The ideas of Erving Goffman, Edward Jones, Barry Schlenker, Roy Baumeister and others are being explored. Concepts related to to self-presentation are presented. Different types and functions of self-expression are identified.

The review gives a write-up of the edition, its structure, composition and its material. The guidelines for teaching British literary Modernism, methods and concepts offered in the book are subject to a detailed analysis. The critical appraisal of its innovations, its tendency to extend and revise the canonical topics and the reading list, offer new points of view and unordinary approaches (in contrast with typical university curricula) is followed by critical remarks targeted at its weak points – poor reasoning and certain groundless pronouncements one sometimes comes across, principles that underlie the selection of material in particular chapters and paragraphs, correctness of style and conformity with the conventions of academic discourse. It is also emphasized that the book in question is a fascinating and enriching reading that will be duly appreciated by the students as well as colleagues and all readers interested in the British literary Modernism.

Постановка задачи. Статья посвящена детальному анализу фразеологизмов английского языка различных тематических групп и особенностям их регистрации в англо-английских и англо-русском словарях и справочных пособиях. Рассматривается ряд характеристик, которые отличают фразеологические единицы от свободных словосочетаний. Кроме того, исследуется вопрос включения пословиц в состав фразеологического фонда того или иного языка. Впоследствии отобранные методом сплошной выборки фразеологические единицы классифицируются по различным основаниям, а также проводится детальный анализ особенностей их отражения в представленных изданиях. Результаты. Осуществляется классификация фразеологизмов по следующим категориям: функция в коммуникации, определяемая их структурно-семантическими особенностями, а также тематическое деление. Отдельно рассматриваются фразеологизмы-эвфемизмы, относящиеся к нескольким тематическим группам, среди которых смерть, ругательства и беременность. Выделяются и описываются характерные особенности организации микроструктуры (словарной статьи) каждого отдельно взятого издания. Выводы. На основании проведенного анализа регистрации английских фразеологизмов сделаны выводы о том, что данная лексика получает подробное и точное отражение в справочниках. Проведенный анализ теоретической литературы показал правомерность включения пословиц во фразеологический фонд, поскольку они принадлежат к культурному наследию того или иного народа и воспроизводятся в речи в исходной форме. Тип и адресат справочника определяют особенности организации словарной статьи, а также компоненты, которые входят в нее (дефиниция, переводной эквивалент, иллюстративный пример, грамматическая, стилистическая, региональная и этимологическая пометы, графическая иллюстрация). Statement of the problem. The article is devoted to a detailed analysis of the phraseological units of the English language of various thematic groups and the features of their registration in the English-English and English-Russian dictionaries and reference books. Features that distinguish phraseological units from free phrases are studied. More than that, the question of belonging proverbs to phraseological stock is studied. Then phraseological units selected by the continuous sampling method are classified according to different grounds, and a detailed analysis of the features of their reflection in the analyzed sources is carried out. Results. Phraseological units are classified into some categories according to the following criteria: function in communication, determined by their structural and semantic features and thematic division. Phraseological units-euphemisms related to several thematic groups, including death, curse words and pregnancy are studied. The characteristic features of microstructure organization of each individual source are described. Conclusion. The analysis of English phraseological units registration showed that this lexis is reflected in dictionaries in a proper way. Theoretical literature analysis shows justification of proverbs inclusion into phraseological stock as they are a part of national cultural heritage and are reproduced in speech in the basic form. Further, the author comes to a conclusion that dictionary type and addressee of the reference book determine features of microstructure organization and their components (definition, translation equivalent, illustrative example, grammar, stylistic, regional and etymological labels, graphic illustration).
