Authors: Фаиг Гаджиев, Хуснийя Пашаева Фаиг Гаджиев, Хуснийя Пашаева
Published: June 2023

В статье рассматривается проблема исследования ассоциативных отношений на базах знаний экспертных систем, решение которой представляется в плоскости идентификации подпространств на основе алгоритма сегментации заданного пространства признаков с учетов их нечетких характеристик. Адаптация алгоритма на материалы космических исследований свидетельствует о возможности его использования как компоненты интеллектуального пакета базы знаний. К настоящему времени наблюдается четкая тенденция поддержки информационных технологий, ориентированных на создание и развитие проблемных областей, интенсивная проработка которых не представляется в рамках существующих концептуальных представлений анализа и интерпретации в следствии наличия больших объемов данных, ограничивающих возможности экспертов при их модификации в знания, в системном анализе принятия решений и задания алгоритмических ресурсов исследования. Используемая с этой целью технология Data Mining, считающаяся исходным этапом Кnowledge Discovery in Databases предназначена для обработки таких совокупностей данных с целью выявления новых знаний, представляющих научный, корпоративный и др. интерес [ 1-4].
Последние, будучи выявлены на основе специальных алгоритмов, предназначены для идентификации объектов рассматриваемой проблемной области, как относительно их непосредственных свойств, так и с позиций исследования ассоциативных отношений. Возникающие при этом сложности методологического характера связаны с необходимостью использования алгоритмов кластеризации, выявления ассоциативных связей, разработки нейронных сетей и деревьев решений [5,6]. Следует иметь в виду, что если в задаче кластеризации производится выделение кластеров и их характеристик относительно совокупности исходных данных, а исследование ассоциативных отношений тесно связано с определением локальных и глобальных взаимосвязей между объектами системы, представляемые совокупностью правил изучения рассматриваемых данных, то разработка нейронных сетей, представляющих собой набор соединенных между собой нейронов с фиксированными функциями активизации и переменными весовыми параметрами сети представляется в преобразовании входного вектора в выходной, а что касается деревьев решений – они представляют иерархическую структуру классифицирующих правил типа «если … то …», распознающих класс объекта по информации узла дерева, начиная с его корня, по принципу перехода к правому узлу следующего уровня при ситуации «+» и к левому при «-».
Ключевые слова: База знаний, экспертные системы, ассоциативные отношения, сегментация пространства, лингвистическая переменная.

Investigating The Grammatical Interference of Indonesian-Gayonese EFL Learners
Authors: Munandar Imam
Published: June 2023

This study aimed to investigate the causes of Indonesian interference in the writing of English as a Foreign Language (EFL) students and to examine the types of such interference. In order to figure out the issue of Indonesian grammatical interference, a descriptive qualitative approach was adopted by utilizing fourth-semester students of the English Department IAIN Takengon, Aceh, Indonesia, as the target population for the research. Subsequently, the data was derived from both tests and observations. Data analysis indicates that the students still experienced interference from the Indonesian grammar due to it being their first language. In this research, grammatical interference is divided into two categories: the interference of syntax and morphology. Syntactic interference comprises words, prepositions, superfluous words, and word omission. The most prevalent occurrence of syntactic interference is in the area of prepositions. Morphological interference replicated itself in determiner omission, incorrect determiner usage, subject-verb agreement discrepancies, the incorrect verb 'to be,' incorrect usage of verb tenses, and confusion regarding singularity and plurality. Though, the most prevalent type of morphological interference is the omission of a determiner. It was observed that the disparity in the structure of Indonesian and English grammar accounts for the interference. In addition, another cause was that students typically composed it first in Indonesian and translated it into English.

Numerical Simulation of Electro-Thermal Properties in FDSOI MOSFETs Down to Deep Cryogenic Temperatures
Authors: Ghibaudo Gerard , Balestra Francis
Published: June 2023

An original reformulation of the thermopower S, heat conductivity K and heat capacitance C in bulk silicon for electrons and phonons is first proposed. Closed-form analytical approximations for these coefficients as a function of Fermi level, temperature and/or carrier concentration are developed for implementation in TCAD simulation. These analytical expressions for S, K and C have been employed to simulate the electro-thermal properties of a FDSOI (Fully depleted silicon on insulator) MOSFET versus front gate voltage from room down to very low temperature. The obtained results allow discriminating the electron and phonon contributions to the whole properties. These analyses could be very useful to further performing TCAD simulations of FDSOI MOSFETs down to very low temperature for full assessment of electro-thermal performances.

Today’s intense search for materials with superior functional performance and at lower manufacturing cost but based on novel approaches is evident in all the fields of research and materials including metals, synthetic organic materials as well as for materials derived from renewable resources. Materials research is the foremost discipline today guiding progress in many different and various fields of technological engineering. This is due to the strong interdisciplinarity of this field of research with a great variety of specializations contributing to its advancement. These investigations range from the atomic, molecular, nanoscale size up to complex structures even at the macro-engineering size, all this defining how large this field of research can really be, i.e., nanoscopic control of our macroscopic world. Great advances have been made in recent years in the Materials, e.g., in their engineering, chemistry, physics, biology and many others, including some very novel materials. Research in this field is also accelerating as the fundamental understanding has dawned that is mostly the research and the novelties in this field that will allow great progresses in future to be achieved, even in applications not even thought of today. Who can forget that the flight machine of Leonardo da Vinci could perhaps have fled, hence advancing aviation technology of three centuries if ultralight materials had been available in the 16th century? A clear indication that progress in materials being fundamental to engineering progress was a concept not really understood then, but that it is clearly understood today.

The generalized differential quadrature (GDQ) method is used to study the thermal vibration of thick functionally graded material (FGM) circular cylindrical shells. The nonlinear coefficient effect of third-order shear deformation theory (TSDT) model of displacements on the thermal equations of motion is considered. The parametric effects of FGM power law index and environment temperature on the time responses of stresses and displacements are considered. The linear varied effect of shear correction coefficients on the calculation of stiffness integration is also considered. The simply homogeneous equation is used to find the values of vibration frequency, also the dynamic GDQ discrete equation in matrix form are used to find the values of time response and transient response for the thick FGM circular cylindrical shells.
Study of Magnetic, Optical, Electronic and Thermodynamic Effects in Thallium Rare Earth Disulphides (TlRES2, RE= Tb- Er)
Authors: Annveer  , Rahul Gauram  , Singh Rishi P. , VERMA Arvind Kumar , Praveen Kumar
Published: June 2023

In the present research work, we have investigated density of electronic states, electronic band structure, magnetic structure, optical spectra and temperature dependent thermodynamic characteristics of thallium rare earth sulphides, TlRES2 (RE: Tb-Er) using FP-LAPW method and PBE-GGA exchange correlation within DFT. The electronic structure pointed out that TlRES2 compounds show half metallic character. The magnetic moment and spin polarization calculations prove that TlRES2 are fully spin polarized compounds with ferromagnetic nature. Optical spectra show that intraband transitions occur in infrared (IR) regime due to half metallic character of TlRES2 and behave as opaque in ultraviolet (UV) region. High refractive index in IR regime also show metallic character and high peak in UV regime show slow propagation of light in UV regime. The reflection coefficient is found maximum (~50–60%) in UV regime. Greater energy loss has been seen on the higher energy side, which corresponds to the stimulation of plasmons by electrons moving through the compounds. Plasma resonances lead to the frequent peaks at ~ 6.0 eV, 11.0 eV, and 12.0 eV. According to calculations made using the quasi-harmonic Debye model, TlRES2 compounds are dimensionally less stable (i.e., much hard), have poor thermal conductivity, and experience faster-than-average disorder with increasing the temperature.
Effect of CeO2/Ag2O on Etching Ratio and Crystallization Shrinkage of Photosensitive Glass-Ceramics
Authors: Lin Bin
Published: June 2023

Based on Li2O-Al2O3-SiO2 system, photosensitive glass-ceramics with different CeO2/Ag2O ratios were prepared using the melting method. To improve the yield of through-hole processing in photosensitive glass-ceramics and the service life of Micro Electro Mechanical systems (MEMS), the effect of CeO2 content on the transmittance of various samples before and after UV exposure was examined. Additionally, the effect of CeO2/Ag2O ratio on the crystallization shrinkage and etching performance of photosensitive microcrystalline glass was studied both before and after heat treatment. The research results indicate that the optimal CeO2/Ag2O ratio in the photosensitive microcrystalline glass component is approximately 0.03%/0.12%, and the transmittance of the basic glass sample is about 50.8% (@ 310 nm, 1mm thickness). The crystallization shrinkage rates before and after glass exposure are 0.08% and 0.26%, respectively. The highest etching ratio is about 18:1.
Characteristic Compressive Strength of Concrete with the Use Granite Powder Additive
Authors: Azunna Sunday U. , Okolo Chidi J.
Published: June 2023

Granite Powder (GP) is industrial byproducts generated from the granite polishing and milling industry in powder form. The byproduct is left largely unused and is hazardous materials to human health because they are airborne and can be easily inhaled. GP was used as an additive to the concrete to explore the possibility of increasing the mechanical properties (compressive strength) of the concrete. The slump, compressive strength and water absorption test were performed on fresh and hardened concrete. The addition of GP to concrete to serve as an additive shows an improvement in the compressive strength of the concrete. The highest 3-day compressive strength (23.03 N/mm2) was recorded at 10% GP addition level while the lowest 3-day compressive strength (20.47 N/mm2) was recorded at 2.5% GP addition level.  The highest 28-day compressive strength (28.29 N/mm2) was recorded at 10% GP addition level while the lowest 28 days compressive strength (27.40 N/mm2) was recorded at 2.5% GP addition level. Peak compressive strength of 33.40 N/mm2 was obtained at 56 days when 10% GP was added in the concrete production. The workability of the concrete decreased with increase in GP replacements. Therefore a higher water to cement ratio will be required to maintain a certain level of workability. In conclusion, employing GP as an additive in concrete helped in boosting the mechanical properties of concrete. The GP at 10% addition is the best choice among other concrete mixtures as it is equivalent to grade 30 concrete suitable for producing post tensioned concrete.
Teleconnection between the Low Index Phase of Southern Oscillation and Precipitation Patterns over the Southeastern United States
Authors: Lee Seungho
Published: June 2023

The purpose of this analysis is to examine the spatiotemporal extent to which the extreme phase of Southern Oscillation affects precipitation patterns over the southeastern region of the United States. Composite and harmonic analyses using monthly precipitation data were conducted based on the 2-year composite resulting in harmonic dials, which represent the spatial coherence of the candidate regions. For the candidate regions identified in the harmonic dial maps, aggregate composite and index time series of precipitation were analyzed to determine the core regions which represent the temporal consistency in relation to the low index phase of Southern Oscillation (LISO) events. As a result, the precipitation patterns of the core regions, North Region (UR), Middle Region (MR), and South Region (LR), were influenced by the occurrence of the extreme phase of SO events, with SR having the greatest response. During the LISO cycle, the harmonic dial tends to face southeast in UR, northeast in MR, and east in LR. Furthermore, the spatial coherence rates of the three core regions range from 0.94 to 0.99, and the temporal consistency rates are 0.76 to 0.83. In addition, from the cross-correlation and annual cycle analyses, the seasonal and annual effect of LISO forcing on the precipitation variability over the three core regions can be recognizable. In conclusion, Southern Oscillation phenomena have a great influence on the precipitation patterns over the southeastern region of the United States.

Authors: Egbide Ben-Caleb , Ugochukwu Madugba Joseph , Ijeoma Innocent Favour
Published: June 2023

This paper was set out to investigate the functional rapport amid budgetary controls and organizational survival of manufacturing companies in Nigeria. The major problem that motivated this study is incessant collapse of manufacturing companies as a result of lack of proper budget preparation and embracing of budgetary control measures to enhance their profitability. The study adopted the Ex-Post-facto research design it covered listed manufacturing companies in Nigeria for a period of five years 2015-2019. The independent variables were decomposed into a change in operating costs, sales growth and change in operating profit, while the dependent variable was organizational survival proxied by the age of the company. Data were got from the yearly accounts of the selected companies and analysed using descriptive statistics and regression. The result suggests that budgetary control is not a significant determinant of survival of manufacturing companies in Nigeria. This implication of this finding is that manufacturing companies in Nigeria are not fully embracing budget and budgetary controls or that they prepare and not implement it fully. Thus, the study recommends that the management of manufacturing companies should as matters of urgency employ budgetary controls that assist them greatly in controlling changes in the operating costs.

Launch of Universal Journal of Financial Economics
Authors: Hao Yu
Published: June 2023

Financial economics is an exciting new field of study that integrates the theory of finance and financial institutions into the main body of economic theory. It draws on insights from general equilibrium analysis, information economics, and the theory of contracts, and develops the main ideas in finance theory, including the CAPM, arbitrage pricing, option pricing, and the Modigliani-Miller theorem within an economic framework. There are various forms of financial resources (also known as financial instruments), including currency, bonds, stocks, and their derivatives. Although they bring different benefits and risks, they all have a common feature. That is, people expect to create more value in the future through them, and obtain maximum satisfaction in the process of financial resource allocation. Financial economics has developed into a science to study the effective allocation of financial resources. It is of great practical significance to deeply explore the future development process of financial economics for achieving sustainable and stable economic development.

The impact of asymmetry of information and different ambiguity reactions on insurance demand
Authors: Werner Katarzyna
Published: June 2023

We extend the model of ex-ante asymmetric information in the insurance market of Stiglitz (1977) by incorporating consumers’ reactions to uncertainty.  Specifically, we assume that some agents are able to assign a precise probability measure to the event of loss (Savage, 1954), whilst others are not.  The behavior of the latter group complies either with proba-bilistic sophistication or ambiguity aversion as modeled by maxmin expected utility (Gilboa and Schmeidler, 1989). When the former class exhibits sufficient pessimism, these two types are virtually indistinguishable when exposed to rare hazards. Thus, pooling constitutes as an optimal solution to the problem of the monopolist.
A Study on the Effect of Precious Commodity Prices and Macroeconomic Fluctuations on Cryptocurrency Trading in India
Authors: Pangam Viraj , Basel Sayel
Published: June 2023

The role of currency in the functioning of the global economy is undeniably of utmost importance to people and governments, whose trust in monetary authorities is the sole provider of value to most of the world’s money which is in the form of fiat currencies. An alternative means of value exchange called cryptocurrencies operating entirely through the internet has the potential to dilute public trust in fiat currencies due to many advantages including fiscal decentralization among others. This study examines the relationship between key macroeconomic variables namely bond prices, dollar exchange rates and the price of gold and its derivatives and cryptocurrency trading in the Indian context. The daily frequency data is collected after the Indian Supreme Court’s judgement in March 2020 which overturned a ban on cryptocurrencies which was imposed before it. We aggregated the data using Principal Component Analysis and examined the short-run and long-run relationship between the variables and cryptocurrency trading using Toda Yamamoto Granger Causality Tests and ARDL Error Correction Model. The results reveal valuable insights about public perception of cryptocurrencies either as an investment asset or as a medium of exchange by examining the significance of individual independent variables in both the long and short run.
