Opis:
The underwater environment is tough and demanding as a communication channel for ultrasonic signals. The channel transmission characteristics in marine and inland waters depend much on local bathymetry and changing weather conditions. The architecture and performance of a reliable underwater acoustic communication (UAC) system should allow real-time adaptation of its transmission parameters to a large variety of possible channel characteristics. The paper presents an adaptation procedure based on the WSS-US statistical model developed for wireless telecommunication systems. The channel is there characterized by measurements of instantaneous channel impulse response being then a basis for estimation of the channel statistical characteristics and extraction of related parameters in the phase of communication handshake, and next used in the adaptive design of digital communication system transmission settings recorded at the physical and link layers of the communication protocol.

Opis:
Tough transmission properties of shallow water acoustic channels (SWAC) highly limit the use of underwater acoustic communication (UAC) systems. An adaptive matching of modulation and signaling schemes to instantaneous channel conditions is needed for reliable data communications. This creates, however, unique challenges for designers when compared to radio transmission systems. When communication system elements are in move, the accuracy of both the measurements of channel impulse responses and estimates of transmission characteristics is strongly limited, due to rapid variations of the channel performance. This paper describes communication tests of a model of the orthogonal frequency division multiplexing (OFDM) data transmission system. developed by the authors. The measurement procedures and signal processing algorithms were, first, tested in reverberant air-acoustic channels available in the laboratory, and, next, verified in natural conditions in a lake. The air acoustics trials prove to be effective and methodically correct.

Opis:
In the article the authors propose a method for load-balancing of network resources for the case which uses a routing protocols. In the first part of the article the authors present currently used algorithms for load balancing and possibilities of their modification. Through the introduction of additional hardware components for each node: the agent and the probe; it is possible to monitor and control the current system performance. The whole analyzed network is treated as a complex system. This allows to eliminate overloading of route nodes (through ongoing analysis of the optimal operating point for a given node). Load balancing can be achieved using a modified mechanism of ECMP. The proposed approach allows for dynamic adjustment of load to network resources and thus effectively to balance network traffic.

Opis:
The article is devoted to the development of a method for increasing the efficiency of communication channels of unmanned aerial vehicles (UAVs) in the conditions of electronic warfare (EW). The author analyses the threats that may be caused by the use of electronic warfare against autonomous UAVs. A review of some technologies that can be used to create original algorithms for countering electronic warfare and increasing the autonomy of UAVs on the battlefield is carried out. The structure of modern digital communication systems is considered. The requirements of unmanned aerial vehicle manufacturers for onboard electronic equipment are analyzed, and the choice of the hardware platform of the target radio system is justified. The main idea and novelty of the proposed method are highlighted. The creation of a model of a cognitive radio channel for UAVs is considered step by step. The main steps of modelling the spectral activity of electronic warfare equipment are proposed. The main criteria for choosing a free spectral range are determined. The type of neural network for use in the target cognitive radio system is substantiated. The idea of applying adaptive coding in UAV communication channels using multicomponent turbo codes in combination with neural networks, which are simultaneously used for cognitive radio, has been further developed.

A variety of communication channels, which can use the organisation meant that the process is more difficult and requires huge effort, work, and learn in a very short time. The domain of specialists, PR is dialogue with the environment, is already known to many of the tools of PR, but it's just the Internet promotes the improvement of this interactive communication. Every action that we take on the Internet has a dimension of all forms must be present but PR surrounded with special care. Internet deep into relationships between an organization and its environment. Society is not able to permanently trust organization or institutions, which make sense, the aims and principles of ac-tion does not understand. PR communication methods with the environment, these classic with modern, permeate each other. This article attempts to clarify what is communication with the environment and what changes occur in the communication process as a result of digitisation in the practice of the use of PR tools.

Opis:
W komunikacji wewnętrznej przedsiębiorstw coraz większą rolę odgrywają metody elektroniczne. W celu określenia, w jakim stopniu są one wykorzystywane i uznawane za przydatne w zarządzaniu bezpieczeństwem i higieną pracy przeprowadzono badania w 86 przedsiębiorstwach. Wyniki badań wykazały, że klasyczne metody przekazywania informacji na tematy bhp (na zebraniach, w formie pisemnej oraz znaków graficznych, podczas dyskusji nieformalnych) są stosowane znacznie częściej niż elektroniczne i oceniane jako skuteczniejsze. Dominują one również wśród metod nowo wprowadzanych w ciągu ostatnich 3 lat w badanych przedsiębiorstwach.

Opis:
Media społecznościowe (SM) to kanały komunikacyjne umożliwiające interakcję między internautami za pomocą różnych technologii komunikacyjnych. Media te opierają się na relacjach między różnymi podmiotami. Mogą to być relacje typu B2C, B2B, C2C, B2A itd. Obecność marek konsumenckich (B2C) w mediach społecznych jest już powszechna. Konsumenci cenią marki w SM, szczególnie na Facebooku i Twitterze, zaś firmy zbierają rzesze fanów i starają się pozyskać ich sympatię, wykorzystując gry, aplikacje czy konkursy. Zainteresowanie obecnością marek biznesowych (corporate Brand - B2B) w mediach społecznościowych nie jest jeszcze tak popularne, jak w przypadku marek konsumenckich, lecz równie ważne. Za decyzjami biznesowymi o zakupie produktów i usług stoją przecież ludzie, którzy są obecni w SM i poszukują tam informacji dotyczących produktów i usług. Wiedzę tę następnie mogą wykorzystywać jako przedsiębiorcy. Firmy obecne w SM mogą osiągać lepsze wyniki finansowe niż te, które nie korzystają z tego medium. Aby osiągnąć realną wartość biznesową, firmy muszą jednak zaplanować odpowiednią strategię działania w SM. W artykule przedstawiono możliwości, jakie oferują media społecznościowe markom biznesowym.

Opis:
Together with the development of information and communication possibilities of the Internet there is an increase of the role of the customer as the partner in the process of co-creating innovation with the utilization of widely understood model of open innovations. The aim of the article is the assessment of the efficiency of communiaction channels used by firms in relations with the customer. In the assessment there were used findings of research carried out among students who declared activities in scope of: notifyings innovative ideas, testing of products (services) or undertaking the role of a consultant. The assessment took into account the criteria of comfort, speed and efficiency from the perspective of customer and the reaction of a company in the given channel of communication. E-mail, sms, forum, blog, community portal are comfortable but their utilization by companies requires improvement in respect of rate of reaction and efficiency. The channels of communication in the synchronous mode were highly evaluated in respect of efficiency and comfort: telephone, chat, video conversation and Skype. The best but still little widespread solutions are platforms for ideas reporting and the collaboration with the user which are created within company's portals.

Opis:
Current trends in global development (migration processes, hybrid wars, global pandemics, multiculturalism) bring new challenges for nation states. The level of international competitiveness and subjectivity of a modern state depends on the successful positioning of its political brand, secured by the choice of adequate tools for achieving the goals and objectives. This research aims at studying the peculiarities of the public diplomacy resource potential and its use in the process of political branding in Germany. The research methodology combines system and axiological approaches, as well as discourse analysis; this helps to reveal the structural relationships within the brand, and their correlation with the peculiarities of national political and economic development and global trends. The content of the political brand is studied through the prism of the interaction of the public (politics, economics, public administration) and national (mentality, culture, traditions) components that correlate with the level of political and economic development. National political leaders, public and political institutions play a leading role in generating the key message of a state. It is proved that public diplomacy expands the possibilities of successful implementation of economic, political, socio-cultural initiatives of the state, based on partnership and cooperation with representatives of the international community. The main tools of public diplomacy include setting the agenda, synchronization of information messages by government agencies, the use of a wide range of communication channels and special events aimed at building trust and lasting relationships between international actors. The article pays special attention to the study of the content of the branding campaign «Land of Ideas». It presents Germany as an active actor in the international political space, focused on the use of brand-new technologies in all spheres of society to ensure sustainable development. The authors prove that the current branding campaign focuses on economic (sustainable development and citizens’ welfare), technological (technological innovation, energy efficiency, environmental safety), and cultural (dialogue, intercultural communication) aspects. The key ideas of the branding strategy are sustainable economic development, manufacturability and digitalization, environmental friendliness and energy efficiency, partnership dialogue and cooperation. German public authorities are actively involved in the process of political branding, which is carried out at the internal and external levels through public diplomacy. The key ideas of the political brand are presented to the domestic public through constant two-way communication on specialized online platforms, meetings of high-ranking officials with representatives of municipalities, and citizens’ potential is actively involved in various innovative projects. The process of state branding in Germany is synchronized with key global trends – environmental security, climate change issues, energy efficiency. In this context, Chancellor A. Merkel and government agencies are actively cooperating with the EU and other international organizations, participating in forums, summits and online discussions. The experience of German political branding is relevant for other countries in the context of its content, synchronization of government and society, and the use of public diplomacy.
