A note on the potential function of an arbitrary graph H

Given a graph H, a graphic sequence ? is potentially H-graphic if there is a realization of ? containing H as a subgraph. In 1991, Erd?s et al. introduced the following problem: determine the minimum even integer ?(H,n) such that each n-term graphic sequence with sum at least ?(H,n) is potentially H-graphic. This problem can be viewed as a ?potential? degree sequence relaxation of the Tur?n problems. Let H be an arbitrary graph of order k. Ferrara et al. [Combinatorica, 36(2016)687-702] established an upper bound on ?(H,n): if ? = ?(n) is an increasing function that tends to infinity with n, then there exists an N = N(?,H) such that ?(H,n)? ?~(H)n + ?(n) for any n ? N, where ?~(H) is a parameter only depending on the graph H. Recently, Yin [European J. Combin., 85(2020)103061] obtained a new upper bound on ?(H,n): there exists an M = M(k,?(H)) such that ?(H,n) ? ?~(H)n + k2-3k+4 for any n ? M. In this paper, we investigate the precise behavior of ?(H,n) for arbitrary H with ?~?(H)+1(H &lt; ?~(H) or??(H)+1(H) ? 2, where ??(H)+1(H) = min{?F)|F is an induced subgraph of H and |V(F)|= ?(H) + 1} and ?~?(H)+1(H) = 2(k-?(H)-1)+??(H)+1(H)-1. Moreover, we also show that ?(H,n) = (k-?(H)-1)(2n-k+?(H))+2 for those H so that ??(H)+1(H) = 1,?~?(H)+1(H)=~?~(H),?~p(H) &lt; ?~(H) for ?(H) + 2 ? p ? k and there is an F &lt; H with |V(F)| = ?(H) + 1 and ?(F) = (12,0?(H)-1).

A quasi-experimental method of pretest/posttest design was used through an experimental group and a control group. Specific materials were designed and produced for this research. All these materials were subjected to expert judgement. The results show that the use of the instructional video was more than positive in the different variables under study.
THE EFFECTIVENESS OF TEACHING VOCABULARY BY USING PICTURE MEDIA TOWARD STUDENTS’ SPEAKING ABILITY AT EIGHTH GRADE STUDENTS OF SMP IT AL ASROR SEKAMPUNG

&#x0D; The vocabulary is an important part in speaking. If we learn grammar, speaking, listening, without having the problem, the writer must give a good strategy in teaching vocabulary to increase all of them, especially in speaking skill. In Junior high school level, English is introduced as a new subject. Most of the students never learn it before. The writer thinks that vocabulary mastery is the most important, because vocabulary is an essential means in teaching language skill, especially in speaking skill. Students who understand a vocabulary will not be misled in interpreting the meaning of the vocabulary. When they have known the vocabulary, ofcourse they can speak easily. This research is used quantitative reseach. Researcher test hypotheses that are stated at the beginning. The Concepts are in the form of distinct variables. Measures used are systematically created before data collection and are standardized. The data are in the form of numbers from precise measurement. Theory is largely causal and deductive. Procedures are standard, and replication is frequent. Analysis proceeds by using statistics, tables, or charts and discussing how what they show relates to hypotheses. The result of this research is student can easier understanding of learning vocabulary and more interest about the media, the student’s speaking ability also influenced by learning vocabulary.
Liudmyla Heorhiivna Tsurkan – personality and pedagogue

The article is devoted to the problems of vocal pedagogics on the example of creative life of outstanding teacher, professor of the Department of solo singing of Kharkiv I. P. Kotlyarevsky National University of Arts Liudmyla Heorhiivna Tsurkan. The goal of an article is to reveal the path of professional growth of L. H. Tsurkan and to systemize her pedagogical principles. The article uses such methods of research as historical, analytical and stylistic. The relevance of the study is due to the lack of generalizing work on the professional development and pedagogical principles of the singer and teacher. Scientific novelty lies in the coverage of previously unknown facts of the biography of L. H. Tsurcan and systematization of its methodological principles. Results for discussion. L. H. Tsurkan is an opera singer who created more than 30 leading images of repertoire for soprano, used her own experience in performance and creative premises in her own pedagogical activity, which she started in 1976 on the Department of Solo signing of Kharkiv I. P. Kotlyarevsky National University of Arts. On several examples, the questions of technology, including methodology of development of vocal apparatus, are researched. She combined fundamental principles of Italian, Russian and Ukrainian schools of singing as well as enriched these methods with new skills and ideas, which help young singers to liberate their creativity, and develop their emotional memory and independence of creative search. On some examples principles of singing are analyzed which were given to the students by L. H. Tsurkan. These are low-rib breath, free state of oropharynx. High position is combined with low breath. The power of voice is coordinated with chest and head resonance or with their combination with dominance of one or another on several parts of the voice. It is stressed that while working on technique and right breath, she always bore music in her mind. A breath is a mean of performers expressiveness. Thus, it has to change according to style of the work. Significant role of diction is stressed, which draw a lot of attention of L. H. Tsurkan. Conclusions. Renowned professor and Master of vocal pedagogics, she created experience and methodical devices which are used not only by her former students, but as well by her colleagues and young pedagogues. These are: relentless and inspired work; indefatigable search for ways and methods of correction of problems, and perfection of already achieved skills; constant development, both cultural and intellectual; ability to play musical instruments and knowledge of theory and history of music; ability to speak foreign languages, which gives an opportunity to learn an incredibly wide variety of musical literature. Not only does this all enrich both spiritually and professionally, but also it is a straightforward path to success and more complete realization of personality. The article uses reminiscences of L. H. Tsurkan’s daughter about life of the pedagogue, video-recordings of master-classes and lessons of the Professor.
Coping with Reading Difficulty Using Socio-Affective Strategy

Reading academic texts requires learners to use a variety of skills and strategies. Among the main types of academic reading are (a) reading for quick reference, (b) reading for pleasure and also (c) critical reading. Students who have just left high schools, reading academic text may post some problems. Hence, readers face challenges when they read academic texts. Different readers face different difficulties when they read different types of texts. Some readers face linguistics challenges while some face non-linguistic challenges when they read academic texts. Fortunately, many academic readers have their own way to cope with the difficulties in reading. This study explored the problem readers face when they read academic texts. This study also investigates show readers use schemata and socio affective strategies to help them cope with difficulties when reading academic texts. The instrument used is a five Likert scale survey with 33 items. Data is analyzed using SPSS version 26 to reveal frequency of responses. Findings bear interesting pedagogical implications to the teaching and learning of academic reading.
The performing principles of the Ukrainian pianist and teacher Viktor Syriatsky

Background. Viktor Syriatsky is a pianist, pedagogue, composer and scholar, a unique figure in the piano art of the second half of XX century. His talent as a pianist is incredibly multi-faceted, he brought up several generations of famous musician during 35 years, while working at Kharkiv I. P. Kotlyarevsky National University of Arts. The aim of the article is to reveal basic principles of the performing style of Viktor Syriatsky and essence of his artistic aspirations. The relevance of chosen facet of the research is caused by the fact that its results might be used in the work of performer on the interpretation of musical piece, and in practice of teaching, including such courses as history and methodology of performance art. Research methodology. In order to reveal the chosen theme, complex musicologically-analytical approach is used, which is founded on the works by such scholars as B. Asafev, S. Savshinskiy, S. Feynberg, Ya. Milshteyn, D. Rabinovich, N. Rastopchina, G. Neygauz, modern research – works by N. Drach (2006), I. Belonosova (2014), O. Fedorovich (2014) etc. These works allowed to regard performance style as an attribute of the personality of the performer himself, which might be dependent on his own physiological and psychological traits, from his mentality and worldview. Results for discussion. All his life V. Syriatsky consciously and unremittingly worked on his performer style. The play of the pianist draws attention from the very first sounds. His sound is full mellow, warm, resonant, equally noble even in mighty ff and in soft pp, always full and resonant. His sound is a tool, not the goal itself. The best sound is the one, the most fully. embodying artistic content. Mastership of V. Syriatsky is connected as well with rich usage of textural performer’s means and pedal. Understanding performance art as the one bearing artistic content, he regarded intonation to be the most important mean of musical expressiveness. Apart from performer’s intonation for him the was not truly valuable and significant recreation of the author’s idea. His play stood out apart from the play of other pianists by naturality of the performance: whatever he played, it became alive under his hands. The master was incredibly careful in his choosing of temporal organization in music such as tempo. He also underlined importance of the performer’s rubato. At the same time, the ideas of the composer were a law for him. Conclusion. In performance style of V. Syriatsky there was incredible calmness and sage of a man who went through diverse school of life.
The fixed point property of the infinite K-sphere in the set Con*((Z2)*)

In this paper the Alexandroff one point compactification of the 2-dimensional Khalimsky (K-, for brevity) plane (resp. the 1-dimensional Khalimsky line) is called the infinite K-sphere (resp. the infinite K-circle). The present paper initially proves that the infinite K-circle has the fixed point property (FPP, for short) in the set Con(Z*), where Con(Z*) means the set of all continuous self-maps f of the infinite K-circle. Next, we address the following query which remains open: Under what condition does the infinite K-sphere have the FPP? Regarding this issue, we prove that the infinite K-sphere has the FPP in the set Con*((Z2)*) (see Definition 1.1). Finally, we compare the FPP of the infinite K-sphere and that of the infinite M-sphere, where the infinite M-sphere means the one point compactification of the Marcus-Wyse topological plane.

Lambda-type Three-Level Laser Coupled to Squeezed Vacuum Reservoir

The squeezing, entanglement, and statistical properties of light produced by lambda-type three-level laser coupled to squeezed vacuum reservoir have been studied.We have determined the quadrature variances mean as well as variance photon number photon for cavity modes with the aid of the solutions of c-number Langevin equations associated with the normal order.The results show that the light produced by the system under consideration in squeezed state.The squeezed vacuum reservoir enhances both the quadrature squeezing and mean photon numbers.In addition, the mean photon number of mode b is greater than that of a if more atoms injected with state |a>.We have calculated the quadrature variances of the cavity modes, the result shows that the light produced by the system under consideration is in squeezed state and the squeezing occurs in the minus quadrature.The result also shows that the effect of the squeezed vacuum reservoir is not only enhancing the degree of squeezing for the light modes but also to generate the photons for the system under consideration.The system produce entangled two mode light that increase with η and linear gain coefficient but decrease with squeezing parameters.The correlation function of the two modes decreases as η, the linear gain coefficient and increase with squeezing parameter.
A Theory of Approximate Reasoning with Type-2 Fuzzy Set

In this paper, an attempt is made to study approximate reasoning based on a Type-2 fuzzy set theory. In the process, we have examined the underlying fuzzy logic structure on which the reasoning is formulated. We have seen that the partial/incomplete/imprecise truth-values of elements of a type-2 fuzzy set under consideration forms a lattice. We propose two new lattice operations which ultimately help us to define a residual and thereby making the structure of truth- values a residuated lattice. We have focused upon two typical rules of inference used mostly in ordinary approximate reasoning methodology based on Type-1 fuzzy set theory. Our proposal is illustrated with typical artificial examples.
Study on the Profit Model in the E-commerce

E-commerce is an emerging industry. It has brought new opportunities for global economic development. The update of e-commerce technology and the improvement of e-commerce profit models promote the profitability of e-commerce enterprises. Nowadays too much emphasis was placed on theoretical teaching in the e-commerce courses. The courses lack case analysis for learners to better understand the actual situation of e-commerce. This study analyzed the profit model of existing e-commerce companies, and used case analysis methods to find the profit dilemma and effective breakthrough methods for the profitability of two typical B2C e-commerce companies. With disassembling specific e-commerce cases, this study completed the conversion of e-commerce courses from theoretical teaching to case teaching.
Vector generation of contextual sets

As quantum contextuality proves to be a necessary resource for universal quantum computation, we present a general method for vector generation of Kochen-Specker (KS) contextual sets in the form of hypergraphs. The method supersedes all three previous methods: (i) fortuitous discoveries of smallest KS sets, (ii) exhaustive upward hypergraph-generation of sets, and (iii) random downward generation of sets from fortuitously obtained big master sets. In contrast to previous works, we can generate master sets which contain all possible KS sets starting with nothing but a few simple vector components. From them we can readily generate all KS sets obtained in the last half a century and any specified new KS sets. Herewith we can generate sufficiently large sets as well as sets with definite required features and structures to enable varieties of different implementations in quantum computation and communication.
Sparse Training Theory for Scalable and Efficient Agents

A fundamental task for artificial intelligence is learning. Deep Neural Networks have proven to cope perfectly with all learning paradigms, i.e. supervised, unsupervised, and reinforcement learning. Nevertheless, traditional deep learning approaches make use of cloud computing facilities and do not scale well to autonomous agents with low computational resources. Even in the cloud, they suffer from computational and memory limitations, and they cannot be used to model adequately large physical worlds for agents which assume networks with billions of neurons. These issues are addressed in the last few years by the emerging topic of sparse training, which trains sparse networks from scratch. This paper discusses sparse training state-of-the-art, its challenges and limitations while introducing a couple of new theoretical research directions which has the potential of alleviating sparse training limitations to push deep learning scalability well beyond its current boundaries. Nevertheless, the theoretical advancements impact in complex multi-agents settings is discussed from a real-world perspective, using the smart grid case study.

Concatenative Speech Recognition using Morphemes

This paper adopts a novel sub-lexical approach to construct viable continuous speech recognition systems with scalable vocabulary that use the components of words to form the elements of pronunciation dictionaries and recognition lattices.The proposed Concatenative ASR family utilizes combination rules between morphemes (prefixes, stems, and suffixes), along with their theoretical grammatical categories.The constrained structure reduces invalid words by using grammar rules governing agglutination of affixes with stems, while having a large vocabulary space and hence fewer out-of-vocabulary words.In pursuing this approach, the project develops automatic speech recognition (ASR) parameterized models, designs parameter values, constructs and implements ASR systems, and analyzes the characteristics of these systems.The project designs parameter values in the context of Arabic to yield a subset hierarchy of vocabularies of the ASR systems facilitating meaningful analysis.It investigates the characteristics of the ASR systems with respect to vocabulary, recognition lattice, dictionary, and word error rate (WER).In the experiments, the standard Word ASR model has the best characteristics for vocabulary of up to five thousand words and the Concatenative ASR family is most appropriate for vocabulary of up to half a million words.The paper shows that the approach used encompasses fundamentally different processes of word formation and thus is applicable to languages that exhibit concatenative word-formation processes.
Study of Applications of Radial Basis Function Network in Forecasting

Forecasting is a broad research domain for multidisciplinary researchers. Forecasting climatic conditions is a challenging task that is carried out by scientists around the globe. The researchers for Forecasting of the various climatic phenomena have used multiple architectures of Artificial Neural Networks (ANN). Such tasks demand huge analysis on recent and past results to give appropriate with precise results of the forecast. The RBF network has a single hidden layer, simpler structure as well as a much faster training process; therefore, it is a popular alternative to the other ANN architectures. In this paper, we are proposing a Radial Basis Function Network (RBFN) as a machine learning tool for making forecasting. In a variety of real-time packages, that includes the prediction of weather, load forecasting, forecasting approximately a variety of traveller and in various programs RBFN applied.
