Growth of local area network Observatory associated with employee needs to access network resources has led to an increase in the number of computing and network devices. Until recently, we tested performance of these systems excellent manual and most of the problems and faults detected already on the fact the accident occurred. For a small number of network nodes, manual monitoring is not a significant problem, but with increasing the number of nodes troubleshooting becomes a very difficult task for network and system administrators and outage in work of netwok services Observatory may becomes critical. Therefore there was a need to automate the monitoring service network resources and servers.

On behalf of the organizing committee, we are very pleased to welcome you to the 2018 IEEE International Conference on Communications (ICC) in Kansas City, MO, USA. The city was labeled as “Paris of the Plains” back in the 1930s. Kansas City is also known as “the City of Fountains,” with most working fountains than any other cities in the world including Rome. ICC is a flagship conference of the IEEE Communications Society, its origin dating back to 1960s. The theme of ICC 2018 is “Communications for Connecting Humanity”.
This is the first time Kansas City is hosting ICC. Kansas City has a long history of being a leader in communications. Almon Strowger, an undertaker, suspected that the telephone operator (who happened to be the wife of a competitor) was directing calls to her husband’s business. So, he was determined to remove the human operator and invented the first automated telephone exchange in 1889 for which he was awarded a patent in 1891 (US Patent # 447,918). The Strowger system was in use for many years in the telephone network, in some countries till 1980s.
This year’s ICC includes 970 papers selected for presentation in 13 symposiums, including one with 12 selected areas in communications (SACs) in emerging areas. These symposiums range from communications signal processing and wireless communications systems to communication security, and emerging areas such as Smart Cities, Big Data, and IoT. The symposiums papers are presented in 144 oral presentation sessions and 6 interactive sessions over three main days of the conference. Altogether, there are nearly 3,700 authors from 58 different countries. The five largest contributors are China (28.56%), the USA (26.02%), Canada (4.81%), France (4.60%), and the United Kingdom (4.30%). On the other end, we also have an author from each of the following countries: Colombia, Ecuador, Jordan, Kazakhstan, Kuwait, Macedonia, Poland, and Sri Lanka. The paper selection was led by 3 TPC chairs and 50 symposium co-chairs with the support of over 2,400 TPC members reviewing papers along with 30 additional reviewers.
This year’s ICC also presents 24 half-day technical tutorials by experts in the field. There are also 20 technical workshops, where over 312 papers are presented. ICC also features a professional development workshop organized by the Networking Networking Women (N2Women) and Women in Communications Engineering (WICE).
We are pleased to have keynotes from James H. Thompson (Qualcomm), Nick McKeown (Stanford University), Elisa Bertino (Purdue University), Yongxing Zhou (Huawei), John Saw (Sprint), Thyaga Nandagopal (NSF), and Paul Tilghman (DARPA).
We like to thank our generous sponsors for their financial support that has greatly helped put the entire program together: Sprint, Qualcomm, Cisco, Huawei, National Instruments, Nokia, Garmin, Juniper Networks, Samsung, Ericsson, MathWorks, The University of Kansas, and the University of Missouri-Kansas City!
A conference of this size wouldn’t have been possible to organize without the dedication of many volunteers who spent countless hours. For their work, we thank the TPC chairs, symposium chairs, workshop chairs and workshop organizers, tutorials chairs, industry program chairs, publication chairs, student travel grant chairs, local arrangement chairs, finance chairs, TPC members, and reviewers. We also appreciate the feedbacks we received from GIMS and GITC. Lastly, we thank the ComSoc staff for their great work in making this conference a big success.
Enjoy ICC’2018 and enjoy your stay in Kansas City!

A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
The geographic information system (GIS) is based on the first and only Russian Imperial Census of 1897 and the First All-Union Census of the Soviet Union of 1926. The GIS features vector data (shapefiles) of allprovinces of the two states. For the 1897 census, there is information about linguistic, religious, and social estate groups. The part based on the 1926 census features nationality. Both shapefiles include information on gender, rural and urban population. The GIS allows for producing any necessary maps for individual studies of the period which require the administrative boundaries and demographic information.
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
