    Opis:
    The general model of a complex system changing its safety structure, its components safety parameters and its operation cost during the variable operation process and linear programming are applied to optimize the system operation process in order to get the system operation cost optimal values. The optimization problem allowing to find the optimal values of the transient probabilities of the complex system operation process at the particular operation states that minimize the system unconditional operation cost mean value in the safety states subset not worse than a critical system safety state under the assumption that the system conditional operation cost mean values in this safety state subset at the particular operation states are fixed is presented. Further, the procedure of finding the optimal values operation cost is presented and applied to the exemplary complex technical system.

    Opis:
    This work indicates that new and innovative materials used in the construction of floating and stationary marine structures can contribute to increased operational safety in addition to reduced service costs and frequency and other reduced operating costs, including the costs of staff and running maintenance. Such materials include metal-ceramic composites whose properties, such as high resistance to abrasive wear, favourable coefficient of friction, good thermal conductivity and low thermal expansion, allow them to be used in tribological pairs in mechanisms, control elements and actuators of various devices operating in marine power plants, thereby increasing their operational reliability. Properties of metal-ceramic composite foams, i.e. vibration and noise damping, good thermal insulation performance, dissipation of electromagnetic waves and absorption of explosive energy, make them ideal for use in shipbuilding and construction of drilling towers, at the same time increasing the levels of comfort during operation. Composite metal-ceramic foams can significantly reduce the effects of fires as they are durable, water-resistant and creep resistant thermal insulators which can limit the destruction (deformation) of steel structures. This paper presents proposals for the application of these materials to selected technical solutions in offshore structures.

    Opis:
    Applications of VANET (Vehicular ad hoc Networks) networks is focused on monitoring of the safety states of vehicles or roadway by exchanging messages between vehicles and infrastructure so that the applications will be able to help a driver to handle insecure situations. They are able to warn before possible risks which can occur during the process of transportation. Essential tool for assuring of safety communications within developed applications of intelligent transportations systems are cryptography constructions on the basis of digital signature schemes. In order to assuring safety and anonymity within vehicular communications are used pseudorandom authentications methods. The authors in the paper are focused on realization of mathematical model and description of modified cryptographic constructions which are suitable for sensor networks and applications orientated to memory and performance. In these systems it is very important to use signature scheme which do not have only computational safety but must also be effective from the view of performance and must generate short digital signatures in order to communications in real time conditions.

    Opis:
    Common Agricultural Policy of the European Union, on the eve of the new financial framework 2014-2020, is significantly focusing on qualitative factors related to: the quality of life in rural areas, the quality of the natural environment, animal welfare, food safety and the preservation of cultural habits. In other words, agriculture has to provide benefits (specific public goods and externalities) to all members of society for which the government or other political institutions will pay. The objective of this article is to review the literature on the theory of externalities, with particular emphasis on the criticism of the current shape and applicability of the theory. It seems that the theory of externalities will play a main role in the development of recommendations for EU agricultural policy instruments, which take into account the importance of externalities provided by agriculture. Yet, there is no consensus on the applicability of this theory in practice, especially in its current form.
    Wspólna polityka rolna Unii Europejskiej kładzie szczególny nacisk na czynniki jakościowe, takie jak: jakość życia na terenach wiejskich, środowisko naturalne, dobrostan zwierząt, bezpieczeństwo żywności oraz tradycja kulturowa. Innymi słowy, rolnictwo ma spełniać nową funkcję, ma dostarczać społeczeństwu świadczenia (dobra publiczne i specyficzne efekty zewnętrzne), za które zapłaci rząd lub inne instytucje publiczne. Celem pracy był przegląd literatury w zakresie teorii efektów zewnętrznych, ze szczególnym uwzględnieniem krytyki obecnego jej kształtu oraz możliwości zastosowania. Wydaje się, że teoria efektów zewnętrznych będzie odgrywać główną rolę w tworzeniu instrumentów polityki rolnej Unii Europejskiej, których zadaniem będzie wsparcie dla efektów zewnętrznych świadczonych przez rolnictwo. Jednak nie ma konsensusu, co do możliwości zastosowania tej teorii w praktyce, szczególnie w dzisiejszej formie.

    Opis:
    While a system-theoretic approach to the safety analysis of innovative socio-technical systems gains a growing acceptance among academia, safety issues of Maritime Autonomous Surface Ships (MASS) remain largely unexplored. Therefore, we applied a System-Theoretic Process Analysis to develop and analyze a preliminary model of the unmanned shipping system in order to elaborate safety recommendations for future developers of the actual system. Results indicate that certain advancements shall be undertaken in relation to MASS’ software solutions in particular.

    Opis:
    In the aftermath of the sinking of the US-flagged containership El Faro in October 2015, one of the U.S. National Transportation Safety Board’s (NTSB) recommendations was for the National Oceanic and Atmospheric Administration (NOAA) to explore increasing the collection of weather data from ships in order to improve the weather forecast products that they distribute. Currently NOAA runs the Voluntary Observing Ship (VOS) program, where ships voluntarily submit weather observations to NOAA. However, only a small fraction of the thousands of vessels sailing worldwide participate in this program, and VOS weather observations are submitted infrequently, typically four times per day via a mainly manual process. One method being explored to automate and increase the frequency of data submittal is by using the existing Automatic identification System (AIS) equipment installed aboard vessels. Most commercial ships (in particular those subject to the International Maritime Organization's (IMO) Safety of Life and Sea (SOLAS) convention) have a Class A AIS transceiver installed to comply with mandatory carriage requirements. Many vessels not required to carry AIS equipment voluntarily install AIS transceivers (either Class A or B). All of these AIS transceivers (except for the Class B “CS”) can be used to transmit an AIS message 8 (broadcast binary message) by sending the transceiver an appropriately formatted NMEA sentence (BBM). Weather data can be embedded in an AIS application-specific message (ASM) carried by the AIS message 8 and automatically transmitted by the ship. This transmission can be received by terrestrial AIS stations (when in range) or by satellite AIS receivers. The AIS weather data can then be converted into the appropriate format and forwarded to the weather forecasting offices for use in models and weather predictions. This data may also be of use to other researchers monitoring climate change or other environmental factors. By leveraging this existing base of AIS transmitters, the volume of weather data being sent to weather forecast offices and others could be greatly increased. The U.S. Army Corps of Engineers (USACE) and U.S. Maritime Administration (MARAD) have been exploring the feasibility of this concept. Following a simple bench test performed by Alion Science in September 2018, an initial proof-of-concept was tested aboard the MARAD vessel Cape Wrath while moored in Baltimore in October 2018. After this successful demonstration, a prototype was installed on the Massachusetts Maritime Academy training ship TS Kennedy during her training cruise Jan-Feb 2019. During this cruise, the AIS equipment aboard the ship transmitted weather data at 3-minute intervals. Several different ASM formats were tested, including two developed specifically for this test to improve satellite reception. This report will discuss the concept, the demonstrations, and the results to date including the efficacy of the various ASM formats.
