ABSTRACT
The LoRaWAN Technology opens new possibilities for gathering and analysis of distributed data. In the paper we concentrate on its maritime usability which was tested by us in the period from June to August 2018. Measurements of the LoRaWAN network coverage in the Bay of Gdansk area were carried out. Various conditions and places were tested. The research was planned in such a way as to gradually increase the range and control the impact of environmental factors. The results of the measurements confirm the wide application and a broad range of the technology. Combined with cloud computing it leads to new kinds of services and applications.

While working on architectural visualizations, the software developer often has to work with graphic designers who create models in a different environment what can cause many complications. For this reason, it is very important to have some guidelines which can protect both the developer and the designer from commixing mistakes. The paper presents a list of such guidelines based on the authors experience. The reader can treat the paper as a first step in the development of a service based on cloud computing that verifies the correctness of graphical data in urban visualizations.

ABSTRACT
A problem of analytical-numerical modeling of the plane wave propagation from an ocean surface to the atmosphere is considered. We are interested in the thermosphere impact of tsunami waves. We suppose that the transport of energy and the momentum from lower atmosphere to thermosphere heights is due to acoustic waves. A set of expressions for the atmosphere variables (pressure, velocity, entropy) as a function of the atmosphere parameters, time and height is derived and illustrated by plots. The surface water wave parameters, typical for tsunami also enter final expressions for the atmosphere and ionosphere variables.

ABSTRACT This paper outlines a study carried out to answer the questions asked by an architect of the Siena Municipality Office during a conference at our Department on the management of traffic flows through the Siena North city road system. The purpose of the study was to ascertain if changes in the road system introduced and included in the new City Development Plan would resolve the current traffic congestion issues. In order to answer this question, we used the technology for the development of vehicle traffic system simulators which was introduced during our previous projects (TASK Quart. 14 (4) 405, 17 (3) 155, 20 (1) 9, 20 (3) 273).

Despite many efforts, there is still a serious problem in transferring knowledge from research to business. The problem is especially visible in Poland the cooperation of R2B is ineffective. We are trying to solve this problem using some IT support. The manuscript presents some solutions developed at the Gdańsk University of Technology. In particular, the platform called MOST Knowledge is deeply described. Its layer architecture, and some new services which it offers are shown. A new interdisciplinary approach is proposed to communicate and support the cooperation of these different worlds. Summarizing, a short comparison with other available platforms is included and discussed.

In this paper we discuss the evaluation of neural networks in accordance with medical image classification and analysis. We also summarize the existing databases with images which could be used for training deep models that can be later utilized in remote home-based health care systems. In particular, we propose methods for remote video based estimation of patient vital signs and other health-related parameters. Additionally, potential challenges of using, storing and transferring sensitive patient data are discussed.

A specialized database and a software tool for graphical and numerical presentation of maritime measurement results has been designed and implemented as part of the research conducted under the netBaltic project Internet over the Baltic Sea the implementation of a multi system, self organizing broadband communications network over the sea for enhancing navigation safety through the development of enavigation services. The developed software allows tracing graphs of radio connections between shore stations and vessels offshore units, based on historical data including the traffic of ships and their specific parameters collected on the Baltic Sea during the last four years. It also enables preparation of data for network simulation experiments using AIS Automatic Identification of Ships and GPS Global Positioning System loggers installed on shore stations and vessels, taking into account a number of input parameters, such as: time range, coast station selection, ship flags based on MMSI numbers and types and ranges of possible communication technologies used WiFi, WiMax, Radwin, LTE, etc. The created tool has a multi layer architecture that utilizes the MariaDB SQL database, the Apache2 WEB server, and a number of PHP applications. The runtime environment has been built on Linux Debian version 8 and the HP C7000 cluster of the 16 CPU x86 64 architecture. The modularity of the application allows parallel processing and, therefore, optimization of the computing cluster. The database contains more than 70 million records which enables simulation of various topologies with multi hop transmissions and network operations depending on the transmission techniques being used. The database is fully scalable, and allows easy adding of further data collected during subsequent measurement sessions. Additionally, the use of virtualization tools facilitates the future migration to more efficient processing environments, in case of a significant increase in the volume of data. The data recorded in the database allows calculation of statistics for the surveyed networks, and determining the incidence of potential network nodes e.g. by flag complete with their available communication techniques information which is important in determining structures of possible multi hop networks and their performance. The software finds routes for datagrams according to accepted criteria and exports results to a network traffic simulator, and as such is an important part of the framework used for planning next measurement campaigns and determining which communications equipment would be more suitable for vessels.

The European policy of Open Access to scientific research is now one of the key issues discussed in public debates on the future development of scientific communication. The implementation of Open Access tools has significant impact on scientific and economic growth. On the one hand, Open Access accelerates disseminating new research findings and facilitates recognition of authors on a more global scale. On the other hand, Open Access helps provide equal access to knowledge and stimulates innovation. Thus, it has an important role in creating the modern information society and economic growth. International organisations, the European Union and governments of individual countries support the idea of Open Access giving recommendations and guidelines concerning making the outputs of research financed from public funds freely available. The paper aims to discuss the process of preparing and implementing the Open Access policy at the institutional level as well as the functionality and tasks of the Open Repository which is now being established on the Multidisciplinary Open System Transferring Knowledge Platform. The acronym of its name in the Polish language is MOST Wiedzy, which means Bridge of Knowledge. The repository is a project of an archive of scientific publications, research data, scientific dissertations, as well as other documents and sources, created as a result of scientific experiments and other research and development work conducted at the Gdansk University of Technology. It will also be a solution supporting communication between researchers and a platform for cooperation between science and business.

The paper investigates both the causes and effects of the rapid increase in the data volume Big Data and their impact on human cognition. The role of the Internet in distributing and exchanging of such data, and their impact on the growth of the Information Society are emphasized. As a result, Wisdom Science a new kind of research emerges which has the potential to facilitate more advanced solutions in the digital world. In consequence, new kinds of info driven devices, services and systems called smart are developed and applied in almost every aspect of human activities around the world. However, this is not enough for humans to use all those well informed smart devices and systems because, first of all, their decisions should be wise. Therefore, the paper, coming from a cognitive informatics approach defines wisdom and its applications, illustrated by some practical cases. Based on this, relations between knowledge and wisdom are shown, and human abilities corresponding to them are defined. They can decide about a transformation of a knowledge society to a wisdom society.
