Development and implementation of various projects focused on improving standards of energy efficiency and rational use of energy carriers is a priority for numerous enterprises and companies. Modern shipping devotes sufficient attention to improving the environmental performance of the fleet. As part of the strategy to improve environmental safety and energy efficiency, as well as to reduce air and marine pollution in industries, including maritime transport and shipping, a set of steps to improve the ship's energy efficiency is being implemented. This process is carried out in various ways, however, at the same time maintaining the economic indicators of fleet operation. Relevant is the research aimed at analyzing the introduction of energy management systems in the maritime transport and summarizing the experience of operating the ships, which allows to identify a number of proposals, the implementation of which allows to maintain the economic efficiency of transportation. The article offers a review of the main energy efficiency tools and ways to ensure the transport efficiency of existing ships without modernization by operating them at reduced speeds and fuel consumption and thereby minimizing carbon emissions, as well as developing a set of measures to improve the environmental efficiency of cargo transportation.

In recent years, various types of commerce including transport have suffered significant damage and costs due to cyber-attacks. The geographic scope of freight transportation has no boundaries, attacks can be launched almost anywhere there is an Internet connection. Therefore, there is no immunity from the failure of computer systems and information of delivery processes in the networks of organizations and companies engaged in maritime transportation. In addition, while the consequences of cyber-attacks on major shipping lines and ports, as well as the digital systems of logistics companies, can be comprehensively analyzed, the vulnerability of ships remains insufficiently studied. This paper offers an analysis of the risks in the field of maritime freight transport and the main factors of influence such as digitization on the safety of the transport process. The basic threats to the information system of the ship are defined and the techniques of risk analysis for the ship information security is proposed.

Advances in computer systems and innovative technologies along with their implementation into the shipping industry not only enabled efficient data exchange between the ship and the shore, but also created a single integrated information network linking all participants of the process and all elements of the maritime sector. Development of the concept of autonomous ships and automated control facilities for their functionality became the next stage in the evolution of innovations. The process of software adaptation, additional electronic steering systems, optical and digital means of monitoring as well as satellite communication facilities for autonomous ships are among the tasks which require search and development of the solutions. Provision of reliable and safe functioning of such ships in the autonomous mode requires development of models and methods for ensuring their accident-free navigation both in relation to the process of ships divergence and improvement of automatic steering systems of movement and course steadiness. In the given work, the analysis of realization of the crewless navigation and possibility of ship automatic movement control systems advancement on the basis of application of mathematical model for the purpose of enhancement of process of the autonomous ship steadiness on the set course is proposed.

Forecasting of successful implementation of innovative product is the crucial element of decision making process. The purpose of forecasting innovative product realization is to define probable commercial level according to consumer demand. This article highlights the necessity of evaluating the commercial prospects for innovative products. It reviews the most popular methods of assessment of commercial prospects of the innovative products and reveal main drawback of them. The results show, that approaches to commercial prospects assessment for innovative products enables enterprises to go beyond the solely understanding of customer needs, thus enabling them to develop new way of. The authors argue for the improving procedure to assess the commercial prospects through innovative product rating Rankings innovative ideas. It is based on the following criteria’s: level of product uniqueness, level of satisfaction of the consumers’ hidden needs, value of the market segment, expected life cycle, products price, quality level, products design, service, amount of marketing costs, expected rate of innovation profitability. The proposed rating method of assessment of innovative products commercial perspectives would enable engineering enterprises to determine the most successful innovative ideas and to timely reject the ideas predestined to fail. Obtained results due to ranking also help enterprises to overcome barriers, associated with innovation commercialization. At the same time this method can be a start point for marketing innovation.

The necessity of enterprise rating activity based on multiple criteria, as well as the significance of selfrating in modern business environment has been proven. The tools for enterprise rating evaluation, including structure methods for rating, and a system of indicators for rating evaluation of the enterprise’s functioning were developed. Thereupon, technology of enterprises rating evaluation was improved and the procedure for selecting functional strategies for their activities according to rating results (partial and complex ratings and rankings) was proposed.

In this paper we have analyzed the properties of energy localization in time-frequency plane for rectangular pulse shape. The technique of space analysis of time-frequency localization (TFL) properties for pulse shapes was designed. We provide the method of OFDM signal synthesis with proper TFL based on the criteria of compactness and orthogonality. The comparative analysis of LTE system efficiency indexes for rectangular and compact pulses was conducted. The advantage of interference immunity and spectral efficiency for well-localized signals was proved.

By alternating-current electrochemical synthesis, the crystalline complex [{CH2=CHCH2-)2 N-CHO}Cu(NH2SO3)(H2O)] (I) has been obtained, using copper(II) sulfamate and diallylformamide (DAFA) in water-methanolic solution and copper-wire electrodes. The single crystal of the compound was X-ray structurally characterized. The Cu atom possesses trigonal pyramidal coordination, formed by nitrogen atom of sulfamate anion and two C=C bonds of the same DAFA molecule at the equatorial plane and the oxygen atom of H2O molecule at apical position. Hydrogen contacts for the most part by (N)H…O and (Ow)H…O bonds of 1,98(3)-2,24(2) A connect separate moieties of the mononuclear complex into a three-dimensional framework. The effective atomic charges in I are calculated.
