Opis:
The polyadic algebras that arise from the algebraization of the first-order extensions of a SIC are characterized and a representation theorem is proved. Standard implicational calculi (SIC)'s were considered by H. Rasiowa [19] and include classical and intuitionistic logic and their various weakenings and fragments, the many-valued logics of Post and Łukasiewicz, modal logics that admit the rule of necessitation, BCK logic, etc.

Opis:
The article presents two attempts at applying J. Lukas iewicz's three-valued logic to analysis of the so-called gradable properties: T. Czeżowski's so-called ordering logics and J. Martin's attempt to connect Lukas iewicz's logic and the neo-Platonian hierarchy of entities. Unfortunately, those attempts were not successful. It can be noticed that in his approach Czeżowski mixed up gradability of truth with gradability of other properties. Martin found that Lukasiewicz's enriching of the division between truth and falsity with a third value suggests some neo-Platonian ontology in which truth - interchangeable with entity - is subject to gradation. However, he does not give an intuitively convincing way of reducing Lukas iewicz's threevalued logic to the corresponding Boole's algebra of compound properties (hence, to a structure belonging to the classical logic).

Opis:
Starting from the 1930s logicians tackled problems connected with applicability of logic in natural sciences and in many cases they tried to practically apply logic in these sciences. In the article entitled ‘Logicians and logic on study of nature’ it is stressed that the broadly understood formal logic supplies natural sciences, and especially physics, with a paradigm for a method of ordering theses. It is also shown what application of logic laws to natural sciences consists in, and theses are formulated concerning what the laws of classical propositional calculus state. A lot of attention is devoted to the language of modern and contemporary physics. Modern and contemporary physics uses two languages, i.e. the mathematical language and the so-called notional language. The logic of the former language is classical logical calculus. In connection with the notional language logicians construed a lot of systems of non-classical logics in which laws are given that govern the correct use of non-extensional operators connected with such terms occurring in natural sciences as “time”, “cause”, “change” etc. The language of well construed systems of non-classical logics may serve saving, storing and precise communicating the results obtained on the ground of natural sciences.

The paper presents several attempts to express intuition concerning the understanding of knowledge and conviction by means of the conceptual apparatus of many-valued logic. J. Łoś’s pioneer system has been presented here, the system constructed by Ngoc Duc Ho, in which the internal logic in this system is used by the knowing subject as the three-valued logic of Łukasiewicz and the third logical value is understood as “unjustified”, and the four-valued system of N. Belnap, the system that allows for the occurrence of propositions which are evaluated both as true and false.

Opis:
Apart from putting the theses contained in E. Agazzi’s work Why Is It Logical to Admit Several Logics? in an order and making them more distinct, an attempt is made to draw conclusions from the explicit wordings used by that author. Some theses presented in the text are shown against the views of other authors who discussed analogous problems. In this way, as it seems, modification, completing and elaborating has been possible of wordings that approve of the thesis about the existence of many logics that are contained in the analyzed text. Among others, the article emphasizes that Agazzi’s pronouncements about relations existing between standard logic and intuitionist logic cannot be accepted. Also, several remarks are made about the so-called many-valued logics. Agazzi’s theses that well constructed non-classical logics representing proper contents are necessary for representatives of various branches of knowledge is acceptable.

Opis:
In this paper are proposed new many-valued gates K-PLA, T(2/K) and T(K/2) for a logical synthesis of digital integrated circuits. The semi-custom integrated circuit K-PLA has the architecture of a Programmable Logic Array of a type AND-OR and includes new K-valued valves MAX, MIN and GATE(A,j). A gate T(2/K) ( T(K/2)) is intended for transformation binary (K-valued ) entrance words into K-valued (binary) output words. The method of the logical synthesis with the use K-PLA, T(2/K) and T(K/2) allows to reduce nearly three times the chip-area, which is essential for placing of the circuit’s realization of the system of partial Boolean functions .

The calculations of the influence of the self-energy effects on the electron-positron (e-p) enhancement factors and the e-p momentum distributions are presented. The approach bases on the novel formulation of the Bethe- -Goldstone (B-G) equation for the positron in an electron gas where the scattering of the electrons into the states below the Fermi surface due to the self-energy effects is allowed. This equation has been solved and the corresponding e-p enhancement factors and momentum distributions have been found. The agreement between the absolute values of the theoretical calculations and experimental data has improved noticeably.

Opis:
Adults' adaptation troubles that have family background first of all result from dysfunctionality of the family system. A family with many children should not be identified with a problem family. Dysfunctions of the family system may concern any family, irrespective of the number of children in it. Adaptation troubles of persons coming from families with many children first of all result from: the stereotype of a family with many children functioning in the society; the material poverty of the family triggering other forms of cognitive, social, cultural poverty; and deficits in the parents' psycho-social and educational competences. In Poland various initiatives are launched that are directed to families with many children. Undoubtedly such enterprises favor development not only of the very families, but of the whole society as well. However, there are a lot of deficits in the policies directed to the family, especially one with many children. The deficits are observed mainly on the following levels: the macro-social one – a deficit of institutional support for families, especially ones with many children; this type of support requires a change in the binding law regulations and directives resolving social policies towards families, including ones with many children; the micro-social level, where there is a need to support families by means of various systems of social care (natural and specialist ones); this type of aid requires reliable knowledge about problem families areas (about the need for support) and qualified staff giving the care.

Opis:
A communication protocol is a set of rules defined formally that describes the format of digital messages and the rules for exchanging those messages in or between computing systems. The Internet Protocol Suite used for communications throughout the Internet uses encapsulation to provide a way of abstracting protocols and services. This abstraction is grouped into layers of general functionality. For protocols on the transmission layer, many choices exist. But while popular protocols such as TCP, UDP and SCTP do provide connection oriented communication offering reliability, ordering and data integrity, solutions that offer such connections from one point to multiple endpoints are still limited. TCP only supports point-to-point communication and SCTP offers multi-homing functionality, but the transmission is still limited to two logical endpoints. In this paper we use the simple, stateless, transmission model of UDP in order to provide TCP-like services for one-to-many communication that is not limited to just multi-homing or other particular solutions. The protocol supports reliable communication from one endpoint to multiple endpoints in different transmission modes. In order to make it easier for developers to customize the protocol to their needs and possibly extend/modify it in order to create new variants from it, the protocol is developed in user space. Because of this design restriction performance wasn't the main objective of our work, but rather the ease of customization and experimentation with new protocol variants. The protocol was implemented in the C++ programming language using classes with virtual members. New variants of components, such as packet retransmission, can easily be implemented without changing the whole code base.

Opis:
An unflagging interest in describing future events has continuously motivated investigations, particularly in the field of logic.Aristotle, universally acknowledged as the father of logic, proposed a set of certain bases from which we could depart with our investigations. However, these are tools in which, despite their great value, one can perceive certain shortcomings.Over the centuries many attempts have been made to discover a means of describing any sentence, expressed in any grammatical form. One of these attempts is bilattice theory, through which it has been attempted to describe future events. This theory makes use of tools such as vagueness and different forms of semantics including subvaluationism and supervaluationism.In lattice theory itself, the double lattice known as the FOUR lattice (four-valued bilattice logic) is directly employed.After analyzing the structure of a given theory one may easily make use of it in practice, providing examples of its usage.

Opis:
The main aim of the present article is to show what students from Poland and Ukraine think about families with many children. The text includes information about this phenomenon in both countries and results of the research which compares many children families from Poland and Ukraine. The minority of families are these with many children in both countries. Nowadays people are afraid of having a lot of children. It can result from the financial problems of the family. Very often people also perceive children as an obstacle to the self-realization. It seems that social perception of many children families creates the feeling of amazement and compassion rather than kindness. The results obtained in the research show that young people from Poland and Ukraine reinforce families with many children. In spite of the fact, there are differences in the way of perceiving many children families by students in Poland and Ukraine, namely Ukrainians are more optimistic in this matter than Poles. The results also indicate that there are various factors which influence on the difference of opinion including political and economic factors, religious, cultural, environmental and emotional factors. Nowadays, many children families need the great support from the society and the state. It is worth showing the advantages of large families which positively influence on the state. It is also important to pay attention on families with many children because this phenomenon is vulnerable to many threats.

Opis:
On-line communication services were evolving from a simple text-based chats towards sophisticated videopresence appliances. The bandwidth consumption of those services is constantly growing due to the technology development and high user and business needs. That fact leads us to implement optimization mechanisms into the multimedia communication scenarios. In this paper, the authors concentrate on many-to-many (m2m) communication, that is mainly driven by the growing popularity of on-line conferences and telepresence applications. An overlay model where m2m flows are optimally established on top of a given set of network routes is formulated and a joint model where the network routes and the m2m flows are jointly optimized. In the models, the traffic traverses through replica servers, that are responsible for stream aggregation and compression. Models for both predefined replica locations and optimized server settlement are presented. Each model is being followed by a comprehensive description and is based on real teleconference systems.
