2nd Generation Intact Stability Criteria
Opis:
One of the main tasks of the Sub-committee on Ship Design and Construction (SDC) of the International Maritime Organization (IMO) is development of the 2nd Generation Intact Stability Criteria. The paper presents the framework and the approach agreed by the Sub-committee. The framework bases on the concept of stability failure and vulnerability assessment. However, the criteria, standards and regulations developed so far have weaknesses that may prevent some IMO Member States from adoption of the regulations on the Maritime Safety Committee (MSC) level. The paper presents some of the weaknesses that are the most important from the Author’s point of view. Awareness of the weaknesses may facilitate the future work of the Sub-committee and its working groups.

Opis:
Research background: As part of the creation of an effective mechanism for managing financial stability, the tasks of providing an inter-level and cross-sectoral financial equilibrium remain unresolved. So far, clear and unambiguous criteria for financial stability have not been formulated, with which monetary and prudential policies could be related, as well as measures to minimize systemic and individual risks. The problem of creating a system of indicators comes to the fore, allowing the creation of new effective instruments for regulation of financial flows that contribute to the prevention of financial crises. Purpose of the article: The paper proposes a system of indicators of financial stability, which allows for solving the tasks of inter-level and cross-sectoral equilibrium in the selection of regulatory tools for monetary and prudential policy. Methods: We have used real interest rates as a measure of financial stability at the macro level. The real rates have been calculated from time series with nominal interest rate and inflation in the credit market (divided into loans to financial and non-financial organizations and individuals), and in the bond market (divided into corporate, municipal, and federal bonds). The analysis of the market and institutional financial stability of the USA, Russia, Japan, Switzerland, Australia over the period 1984?2014 was done. Then, comprehensive investigation on the financial stability in the Russian Federation in 2014?2017 was conducted. The results have been compared against financial stability of individual banks, which was measured using profit to risk ratio. The latter has been calculated from bank?s financial reports using our method, which had been developed earlier. Findings & Value added: We have developed criteria for qualitative assessment of financial stability and the risk map, which helps to identify the level of accumulated imbalances in the market and institutional environment, as well as in the levels and sectors of the economy. The criteria for selecting monetary and prudential regulatory instruments have been formulated depending on the amount of accumulated risks. The criteria for forming a portfolio of regulatory instruments with regard to their rigidity are proposed.

Opis:
International stability norms included in the Code of Intact Stability 2008 adopted by IMO on 4 December 2008 constitutes the latest set of international requirements on intact stability of ships. However the requirements included in the Code, part of them compulsory (Included in the Part A of the Code), other only recommended (included in the Part B of the Code) are considered as not totally sufficient to assure safety of ships. Because of that, IMO decided that there would be the necessity to develop so called new generation stability criteria covering certain identified hazards, such as parametric resonance, loss of stability in the wave crest broaching, dead ship condition and excessive accelerations when rolling .Those criteria, or rather stability norms, are under development since 2008.The present approach, the work on which is well advanced, is however, not fully satisfactory and several important problems were discovered. This approach may need to be reconsidered or supplemented. The author in the paper presented discusses the weak points of the current approach and proposes possible different approach in order to make future ships safer from the stability point of view.

Opis:
The paper considers three concepts of polynomial stability for linear evolution operators which are defined in a general Banach space and whose norms can increase not faster than exponentially. Our approach is based on the extension of techniques for exponential stability to the case of polynomial stability. Some illustrating examples clarify the relations between the stability concepts considered in paper. The obtained results are generalizations of well-known theorems about the uniform and nonuniform exponential stability.

Opis:
Exploring the stability of states and political systems is of interest to scientists and politicians all around the world. One of the most important questions in this field is the question of the relationship between stability and freedom. This paper considers the relationship between economic freedom and stability with regards to the example of countries of Central and Eastern Europe. The study uses quantitative analysis and the operationalisation of economic freedom through the Index of Economic Freedom (IEF); furthermore, stability is studied through the Fragile States Index (FSI), and the Political Stability and Absence of Violence/Terrorism Index (PSI). The analysis reveals a strong correlation between economic freedom and stability. According to linear regression models obtained by the author, economic freedom has a strong impact on stability. Models show that most of the components of IEF increase stability, whilst some components decrease it. This means that the same factors affect economic freedom and stability in different ways. In particular, taxes have a very positive effect on stability. At the same it is obvious that taxes reduce economic freedom. This fact allows us to resolve the existing contradictions among politicians and scientists, who differently assess the impact of economic freedom on stability. It may be stated that whilst economic freedom has in general a strong positive effect on stability, it can also have a negative effect.

Opis:
Epoxy methacrylate of (E)-1,3-bis(4-hydroxyphenyl)prop-2-en-1-one (EMC) has been synthesized by condensing 1 equivi. (318g) epoxy resin of (E)-1,3-bis(4-hydroxyphenyl)prop-2-en-1-one and 2.1 equivi. (181g) methacrylic acid using 10 ml triethyl amine as a catalyst, 2.5 g hydroquinone as an inhibitor and 350 ml tetrahydrofuran as a solvent at reflux temperature for 1-7 h. Styrene was used as a reactive diluent. The structure of EMC was supported by FTIR and 1H NMR techniques. EMC showed endothermic transition at 118 °C and 307 °C, respectively due to melting and crosslinking followed by decomposition reaction and EMCS showed endothermic transitions at 81 °C and 255 °C due to branched and uncrosslinked EMCS and some physical change. EMC and EMCS are thermally stable up to about 265 and 332, respectively. EMC followed two steps degradation kinetics, while EMCS followed single step degradation kinetics. Jute and glass composites of EMCS were fabricated by hand lay-up technique followed by compression molding under 20 bar pressure and at 120 °C for 4 h. J-EMCS and G-EMCS showed 22.7 and 182 MPa tensile strength; 10.9 and 156.5 MPa flexural strength; 3.1 and 1.6 kV mm-1 electric strength; and 2.2 x 1012 and 2.8 x 1011 Ohm cm volume resistivity. Both J-EMCS and G-EMCS showed excellent hydrolytic stability even in harsh acidic and saline environments and also in boiling water. Observed equilibrium water content at 35 °C for J-EMCS and G-EMCS in water, 10% of aq. NaCl, and 10% of aq. HCl are 8.8, 10.8, and 8.7% ; 5.8, 4.6, and 4.7%, respectively. The composites may be useful for low load bearing housing units, and in electrical, electronic and marine fields.

Opis:
We consider nonlinear non-autonomous multivariable systems governed by differential equations with differentiable linear parts. Explicit conditions for the exponential stability are established. These conditions are formulated in terms of the norms of the derivatives and eigenvalues of the variable matrices, and certain scalar functions characterizing the nonlinearity. Moreover, an estimate for the solutions is derived. It gives us a bound for the region of attraction of the steady state. As a particular case we obtain absolute stability conditions.
Our approach is based on a combined usage of the properties of the "frozen" Lyapunov equation, and recent norm estimates for matrix functions. An illustrative example is given.

At present, intact ship stability criteria have prescriptive nature. At the 45-th Session of SLF Sub-Committee a decision was made to change IMO attitude concerning intact ship stability from prescriptive rules to performance based rules. This paper aims at providing a basic framework for the development of intact ship stability criteria based on a deterministic scenarios concept. The concept is described in general and one simple scenario is calculated in detail. This scenario concerns shifting of a deck cargo.
Obecnie kryteria oceny stateczności statku nie uszkodzonego oparte są na przepisach wynikających ze statystyki wypadków. Na 45. sesji Podkomitetu ds. Stateczności i Linii Ładunkowych podjęto decyzję o zmianie podejścia IMO do oceny stateczności na podejście uwzględniające zjawiska towarzyszące kołysaniom statków. Niniejszy artykuł przedstawia ideę opracowania kryteriów oceny stateczności na podstawie tzw. "scenariuszy". Opisano ogólne założenia oraz przedstawiono obliczenia dla wybranego scenariusza zakładającego przesunięcie się ładunku na pokładzie.

Ship’s Heel
Opis:
The angle of heel on account of turning is one of the mandatory stability criteria for passenger ships. Formula used for calculations of this criterion contained in the International Code on Intact Stability [13] is criticized at present. Agendas of the Sub-committee on Ship Design and Construction (SDC) for the first (2014) and the second (2015) sessions contain the item on revision of this criterion and corresponding regulation. The paper presents some shortcomings of the criterion. Turning tests of a freely maneuvering model of a passenger ship have been executed aiming at gathering data for the future discussion and its facilitation. The paper presents results of the tests together with preliminary conclusions that confirm the need of the revision of the regulation and put forward concerns on application of such values as initial metacentric height (GMo) and righting lever curve (GZ(?)) calculated for a ship laying still for calculation of a ship’s heel caused by turn.

Opis:
This paper presents the properties of the equivalent Thevenin's model of a network as seen from a network receiving node. Such a simplified model can be applied in protective and preventive gear installed at the considered receiving node. Thevenin's circuit can be determined either from of the power system configuration diagram or by use of algorithm based on local current and voltage phas or measurements. Local measurements are used to calculate the derivative of apparent power against the voltage dS/dV. Paper describes the dS/dV algorithm accuracy tests according to the approximate angle of the series system impedance. An important problem of the Thevenin's model updating due to the changing configuration of power system is discussed in the paper. The advantages and disadvanges of both described methods are also presented.
Artykuł przedstawia właściwości modelu Thevenina. Uproszczony model reprezentujący aktualną konfigurację systemu może mieć zastosowanie w automatyce zabezpieczeniowej oraz prewencyjnej montowanej w punkcie odbiorczym. Model Thevenina może być tworzony przy użyciu dwóch metod: korzystając z informacji o pełnej konfiguracji systemu oraz z algorytmu wyliczającego parametry modelu na podstawie pomiarów lokalnych fazorów napięć i prądów. Korzystając z pomiarów lokalnych, wyliczana jest pochodna mocy pozornej po napięciu &S/&V. Przeprowadzono testy dokładności algorytmu dS/dV w zależności od założonego kąta impedancji systemowej. Ważnym problemem, jaki jest poruszony w artykule jest aktualizacja modelu zgodnie ze zmieniającą się konfiguracją systemu elektroenergetycznego. Zmiany mogą być wywoływane zarówno stanami normalnej pracy, jak i awariami występującymi w systemie. Przedstawiono wady i zalety stosowania obu metod.
