The rapid development of the service sector in Russia, observed in the last decade, requiresscientific understanding and technological development, adequate international practice. University professors, undergraduate and graduate students, professionals, commercial companies every day have to face the necessity of "instrumentation" of decisions taken in accordance with the rules and principles of services marketing. In recent years, on the shelves of bookstores appeared many publications covering various issues of marketing character and content. At the same time they themselves draw attention to two important facts: first, Russian specialists persistently imposed foreign, mainly American, experience, and secondly, the Russian authors show slowness in understanding domestic marketing practices. This book reveals many of the secrets of services marketing, analyzes the emerging conflict in this area, provides useful practical advice for professionals working in the service sector. The first section of the book "The theoretical foundations of services marketing," the author, not departing from the common tradition, reveals the most important theoretical principles: the nature and essence of marketing, especially services marketing, research anddevelopment of this type of marketing, marketing environment and consumer behavior. Section Two "Practical marketing in the service sector" is devoted to the problems of the so-called marketing mix, including "four policy": product, price, place and promotion. Beinga limited volume of the book, the author deliberately omits questions adequately covered in the foreign and domestic literature. Its focus is on those practical aspects of marketing which are manifested mainly in the service sector. In the third section, "Management of services marketing," the author focuses the reader's attention on three important components: market research, market segmentation and positioning of the company and its services. Other components of the management process in marketing the reader can easily find in the list of recommended literature. The final section of the book "Marketing services today and tomorrow," sums up the theoretical analysis carried out and reveals some modern technological approaches to the development of marketing plans and programs in the service sector.

To improve the performance of Wi-Fi networks in dense deployments, the recent IEEE 802.11ax standard introduces a palette of features improving spatial reuse. A key property of these features is dynamic changes in transmit power and the interference from the neighboring devices. The paper explains the basic operation of spatial reuse features and shows that their efficiency significantly depends on how the stations select appropriate modulation and coding schemes taking into account the variable transmission conditions. Nevertheless, the majority of existing studies in the literature leave this effect out of consideration, assuming an ideal rate control algorithm and obtaining wrong results. The paper fills this gap and presents a novel statistics-based rate control algorithm that selects modulation and coding schemes taking into account the effects induced by the recent spatial reuse features. With extensive simulation, it is shown that the algorithm significantly outperforms the existing rate control algorithms, providing up to 50% higher goodput and three times lower latencies.
We present an approach based on a two-stage ltration of the set of feasible solutions for the multiprocessor job-shop scheduling problem. On the rst stage we use extensive dominance relations, whereas on the second stage we use lower bounds. We show that several lower bounds can eciently be obtained and implemented.
1. Description of the problem. Instrumental analysis makes it possible to find the arguments of adjudication on the bounders and structure of corpus delicti, its correlation to criminal and filling-up legislation. 2. Initial theses. Corpus delicti is regarded as that expressed in criminal law doctrine result of reorganization of orders of criminal law into other practically necessary form. That happens in the process of theory and practical experience accumulation. The construction of corpus delicti is transformed for practical needs, textually expressed system of features, regulated by criminal law and characterizing deeds as a crime of a definite type. Correlation of construction of corpus delicti with law and doctrine. Corpus delicti, its algorithm. Transition from law regulations to corpus delicti can be done: 1) prog-nostically; 2) within constant analysis of law; 3) in the process of law application. 3. Stages of instrumental building of corpus delicti: prognostic, doctrinal, law applicatory. Instrumental approach to corpus delicti includes within each stage: 1) based on criminal law decision of classification of corpus delicti and its borders; 2) objective description of a factual model; 3) acception of meaning correlated with legal notions and constructions; 4) choice of the construction of the corpus delicti and disposal of characteristics; 5) verification of legitimacy, necessity and adequacy of foundation. 4. Instrumental analysis of disputable questions of understanding and application of constructions of corpus delicti. A. Functions and purposes of application of construction of corpus delicti. Functions of corpus delicti: a) modeling; b) communicative; c) identificatory; d) technological. B. Contents of corpus delicti. Contents of corpus delicti as it is traditionally regarded does not correspond to indications of crime, does not characterize features of social danger; sign of danger of penalty also does go into corpus delicti. Two variants are proposed for the discussion: widening of the borders of corpus delicti by means of introduction of signs of social danger and signs, defining individualization of penalty and to limitate corpus delicti by characteristic of criminally punished act, separating it from contents of guilt and contents of social danger. C. Structure of corpus delicti. There are two problems: division of elements of crime seems to be extremely harsh and inadequate - it is expedient to include signs of special and time limits of act, causal links, crossing signs of objective and subjective sides, first of all consequences and an object of crime, into the structure of corpus delicti. Forms of committing a criminally punished act is a crime commitment in complicity, ideal system, not finished crime.
