Implementation of the optimal construction of a combination device and evaluation of reliability by output voltage

The theoretical propositions of the algebra of logic are considered. It is noted that the current microcircuitry based on the algebra of logic contains logical statements: true (yes) is a logical unit, false (no) is a logical zero. Based on the given logical function: ((ABC)×D + A×(BCD) + A×(BC)×D + (AB)×(CD), frontal, minimal, transformed minimal variants of the combination device are implemented, as well as minimized variants in the bases "AND-NOT" and "OR-NOT". A combination device based on import-substituting chips of 155, 176 series has been designed. The analysis of the obtained devices is made from the standpoint of technical and economic indicators, in particular, an assessment of the number of logic elements used, an assessment of the symmetry of the structure, as a result, a reduction in energy consumption, an increase in performance, improvements in parameters for reliability of functioning, a decrease in weight and size characteristics. Assuming that the law of change of the information parameter U1 is close to linear, taking into account the effect of temperature as boundary values for the elements of the applied microcircuits, taking the values -60 °C and +120°. Accordingly, the parametric reliability of the optimal implementation of the device according to the output voltage parameter is calculated. The conclusion is made about the inverse dependence of parametric reliability on temperature growth. A recommendation is given when evaluating parametric reliability for a number of other information parameters about the need to take into account both the number of chips used and the type of their interconnections.

Positional modeling of the 2T6R robot mechanism

The positional modeling of the 2T6R robot mechanism is done for inverse kinematics, i.e. when the imposed positions of the end effector T, imposed, belonging to the final element 3, are known and the necessary positions and speeds of the two input motors, the two leading elements, are determined, 1 and 6. It is proposed to solve a simple algorithm in the program MathCad 2000, which uses for initiation the logical function If Log. The kinematic output parameters, i.e. the parameters of the foot and practically of the final effector, i.e. those of the point marked with T, will be determined for initiating the working algorithm using the logical functions, "If log (ical)", with the observation that here plays the role of parameters input; is positioned as already specified in reverse kinematics when the output is considered as input and input as output. The logical functions used, as well as the entire calculation program used, were written in Math Cad 2000.

Using multivalued logic for qualitative data analysis

The paper considers a logical approach to data analysis to solve the classification problem. The studied data is a set of objects and their features. As a rule, this is scattered heterogeneous information and it is not enough for a reasonable application of probabilistic models. Therefore, logical algorithms are considered, which under certain conditions may be more adequate. For an expressive formal representation of the relationship between objects and their attributes, multivalued logic is used, and the number of values depends on a specific attribute. Therefore, a system of operations is proposed for variables with different domains of definition. As a result, a decisive function is built, which is a classifier of objects that are present in the studied data. The properties and capabilities of this function are analyzed. It is shown that the logical function, which is a conjunction in the space of rules connecting given objects with their characteristic features, uniquely characterizes the initial data, divides the subject area into classes, possesses modifiability properties, meets the requirements of completeness and consistency in a given area. The paper also proposes an algorithm for its implementation.

Poly Encrypted Text Based on Dynamic Selection and Chaotic Behavior

Indeed, the current cryptography suffers from the rise of the computing power of computers and the advent of quantum computers could be the death knell of these algorithms. Therefore, with this paper, we present a new encryption approach based on chaotic outputs to insure more protection. This approach combines two encryption techniques in addition to random permutation. The first one consists to put in disorder binary data and the second technique is based on conditional logical function. The choice between those two techniques is perfectly random and generated from chaotic outputs. Each process has her own keys which make the encryption more complicated.

A fault-tolerant design for a digital comparator based on nano-scale quantum-dotcellular automata

Purpose Quantum-dot Cellular Automata (QCA) is a new nano-scale transistor-less computing model. To address the scaling limitations of complementary-metal-oxide-semiconductor technology, QCA seeks to produce general computation with better results in terms of size, switching speed, energy and fault-tolerant at the nano-scale. Currently, binary information is interpreted in this technology, relying on the distribution of the arrangement of electrons in chemical molecules. Using the coplanar topology in the design of a fault-tolerant digital comparator can improve the comparator’s performance. This paper aims to present the coplanar design of a fault-tolerant digital comparator based on the majority and inverter gate in the QCA. Design/methodology/approach As the digital comparator is one of the essential digital circuits, in the present study, a new fault-tolerant architecture is proposed for a digital comparator based on QCA. The proposed coplanar design is realized using coplanar inverters and majority gates. The QCADesigner 2.0.3 simulator is used to simulate the suggested new fault-tolerant coplanar digital comparator. Findings Four elements, including cell misalignment, cell missing, extra cell and cell dislocation, are evaluated and analyzed in QCADesigner 2.0.3. The outcomes of the study demonstrate that the logical function of the built circuit is accurate. In the presence of a single missed defect, this fault-tolerant digital comparator architecture will achieve 100% fault tolerance. Also, this comparator is above 90% fault-tolerant under single-cell displacement faults and is above 95% fault-tolerant under single-cell missing defects. Originality/value A novel structure for the fault-tolerant digital comparator in the QCA technology was proposed used by coplanar majority and inverter. Also, the performance metrics and obtained results establish that the coplanar design can be used in the QCA circuits to produce optimized and fault-tolerant circuits.

Minimization of energy efficiency barriers in the context of optimization of management decisions in the process of sustainable development

The object of research is the socio­economic model of the country in terms of energy efficiency factors in the process of economic development. The author has adapted the taxonomy of barriers and identified a new group of barriers inherent in the socio­economic models of countries with economies in transition. Achieving the goals of sustainable development is possible by achieving overall energy efficiency, which is provided by the implemented innovative energy technologies. The ability of the studied subjects to perceive and promote innovative energy technologies is determined by the level of their economic development. When building the concept of energy efficient management, the studied subjects should take into account the exhaustion of primary resources against the background of growing needs. One of Harrington's logical functions was used to determine the level of economic development of the studied subjects. In the indicators of the particular desirability of Harrington's logical function, indicators from 0.37 to 0.8 are the potential for development, currently unrealized in the studied subjects, which is the path to sustainable development. According to certain levels of private preferences, economic agents are given recommendations on the economic feasibility of introducing innovative energy technologies. At the same time, the research process involved the identification and localization of energy efficiency barriers in the studied subjects, which expanded the analytical opportunities in terms of providing practical recommendations. Such recommendations, combined with the private preferences of the studied subjects, allowed to formulate a conceptual scheme to increase the efficiency of energy resources of economic development management. The author proposes measures: scaling of grant financing, decentralization of energy sources, introduction of knowledge, cooperation of communities and in the community, development of entrepreneurship and greening of the environment. Directions strengthen the motivation of management decisions in the context of the effective impact of energy factors on the dynamics of economic development in modern conditions and can be used in the development of current and strategic plans and programs.

REALIZATIONS OF PROJECTION IN NEWS STORY AND EDITORIAL TEXTS

ABSTRACTThis research deals with projection that is used in news story and editorial texts. Projection is well defined as representation of a linguistic experience in another linguistic experience. Projection is equivalent to direct and indirect or reported speech in traditional or formal grammar. As projection is an element of the logical function, it is realized as a clause complex, where there are at least two clauses. With reference to some theories, projection is also potentially realized in the form of single clause and phrase. The aim of this research is to describe similarities and differences with reference to the realizations of projection used in the news story and editorial texts. This research is conducted by using descriptive qualitative design. The data of this research are clause complexes containing projection in news story and editorial texts of Indonesian newspapers. The sources of data are taken from news story and editorial texts of four newspaper publications, namely the daily Kompas, Republika, Waspada and Sinar Indonesia Baru (SIB). The four daily newspapers are assumed to represent national and provincial or local newspapers. Each of the newspapers is represented by seven headlines for news story texts and seven leading articles for editorial texts. The data are analyzed by using interactive model in which the clause complexes are analyzed with reference to systemic functional linguistic (SFL) theory about projection. The findings indicate that there are similarities and diffrences with reference to the realizations of projetion in the news story and editorial texts of Indonesian newspapers.

Monotonic Functions Method and Its Application to Staging of Patients with Prostate Cancer According to Pretreatment Data

Prostate cancer is the second most frequent malignancy (after lung cancer). Preoperative staging of PCa is the basis for the selection of adequate treatment tactics. In particular, an urgent problem is the classification of indolent and aggressive forms of PCa in patients with the initial stages of the tumor process. To solve this problem, we propose to use a new binary classification machine-learning method. The proposed method of monotonic functions uses a model in which the disease’s form is determined by the severity of the patient’s condition. It is assumed that the patient’s condition is the easier, the less the deviation of the indicators from the normal values inherent in healthy people. This assumption means that the severity (form) of the disease can be represented by monotonic functions from the values of the deviation of the patient’s indicators beyond the normal range. The method is used to solve the problem of classifying patients with indolent and aggressive forms of prostate cancer according to pretreatment data. The learning algorithm is nonparametric. At the same time, it allows an explanation of the classification results in the form of a logical function. To do this, you should indicate to the algorithm either the threshold value of the probability of successful classification of patients with an indolent form of PCa, or the threshold value of the probability of misclassification of patients with an aggressive form of PCa disease. The examples of logical rules given in the article show that they are quite simple and can be easily interpreted in terms of preoperative indicators of the form of the disease.

The role of verb semantics in Hungarian verb-object order

Hungarian is often referred to as a discourse-configurational language, since the structural position of constituents is determined by their logical function (topic or comment) rather than their grammatical function (e.g., subject or object). We build on work by Komlósy (1989) and argue that in addition to discourse context, the lexical semantics of the verb also plays a significant role in determining Hungarian word order. In order to investigate the role of lexical semantics in determining Hungarian word order, we conduct a large-scale, data-driven analysis on the ordering of 380 transitive verbs and their objects, as observed in hundreds of thousands of examples extracted from the Hungarian Gigaword Corpus. We test the effect of lexical semantics on the ordering of verbs and their objects by grouping verbs into 11 semantic classes. In addition to the semantic class of the verb, we also include two control features related to information structure, object definiteness and object NP weight, chosen to allow a comparison of their effect size to that of verb semantics. Our results suggest that all three features have a significant effect on verb-object ordering in Hungarian and among these features, the semantic class of the verb has the largest effect. Specifically, we find that stative verbs, such as fed 'cover', jelent 'mean' and övez 'surround', tend to be OV-preferring (with the exception of psych verbs which are strongly VO-preferring) and non-stative verbs, such as bírál 'judge', csökkent 'reduce' and csókol 'kiss', verbs tend to be VO-preferring. These findings support our hypothesis that lexical semantic factors influence word order in Hungarian.
