Published: June 2023

В статье обоснована необходимость дополнительного учета требований жизненного цикла проектируемых систем разработчиками продукции в дополнение к традиционным параметрам контроля. На сегодняшний день актуальной является задача создания автономной, информационной системы проектирования и технического обслуживания судовых установок, в рамках которой можно было бы собирать, систематизировать, анализировать и управлять всей информацией о моделируемых системах, особенностях их эксплуатации для поддержки принятия решений. В статье рассмотрены особенности построения распределенных информационных систем с нечеткой кластеризацией для проектирования и контроля за эксплуатацией судового двигателя. Для формализации этого процесса необходимо разработать распределенную информационную систему судового двигателя, узлы которой смогут одновременно функционировать в пределах рабочего пространства, - так называемого, подхода нечеткой кластеризации относительно способа проектирования, с нахождением нового знания о двигателе с высокоэффективными показателями эксплуатации. Основу этой системы составляет блочно-модульный принцип построения. Модули системы будут опираться на математические модели разного уровня сложности и иерархии. Отдельный акцент сделан на необходимости использования блочно-модульного принципа построения информационных систем и применения математических моделей, которые должны удовлетворять критериям дивергенции, трансформации и конвергенции.
The article substantiates the need for additional consideration of the requirements of the life cycle of designed systems by product developers in addition to the traditional control parameters. To date, the task of creating an autonomous, information system for the design and maintenance of ship installations, within which it would be possible to collect, systematize, analyze and manage all information about the simulated systems, the features of their operation to support decision making, is relevant. The article discusses the features of building distributed information systems with fuzzy clustering for designing and monitoring the operation of a marine engine. To formalize this process, it is necessary to develop a distributed information system of a marine engine, the nodes of which can simultaneously operate within the working space, the so-called fuzzy clustering approach regarding the design method, with finding new knowledge about the engine with highly efficient operation indicators. The basis of this system is the block-modular construction principle. The modules of the system will be based on mathematical models of different levels of complexity and hierarchy. A separate emphasis is placed on the need to use the block-modular principle of building information systems and the use of mathematical models that must meet the criteria of divergence, transformation and convergence.

Regression Model-Based Short-Term Load Forecasting for Load Despatch Centre
Authors: Gochhait Saikat , Sharma Deepak 
Published: June 2023

Forecasting load is an integral part of the planning, operation, and control of power systems. This paper is part of a research effort aimed at developing better energy demand forecasting models for load dispatch centers (LDCs) in Indian states as part of an ambitious project utilizing artificial intelligence-based load forecasting models. In this paper, we present a half hourly load forecasting method for the energy management system of the project that will be used at 33 /11 kV and 0.415 kV substations with good accuracy. The paper uses the half-hourly load consumption dataset collected from MSEDCL for Maharashtra from July 1, 2020 through August 31, 2022. This paper evaluates 24 regression model-based half hourly based load forecasting algorithms for ALE PHATA load based on the load consumption dataset and the collected meteorological dataset. The 24 models in MATLAB Regression belong to five types of regression models: Linear Regression, Regression Trees, Support Vector Machines (SVM), Gaussian Process Regression (GPR), Ensemble of Trees, and Neural Networks. As a consequence of their nonparametric kernel-based probabilistic nature, the GPR family of models demonstrates the best load forecasting performance. Least squares estimation was used to determine the regression coefficients. There is a direct correlation between load in an electrical power system and temperature, due point, and seasons, as well as a correlation between load and previous load consumption. Therefore, the input variables are Wet Bulb Temperature at 2 Meters (C), Dew/Frost Point at 2 Meters (C), Temperature at 2 Meters (C), Relative Humidity at 2 Meters (%), Specific Humidity at 2 Meters (g/kg) and Wind Speed at 10 Meters (m/s). The mean absolute percentage error and the R squared are used to validate or verify the accuracy of the model, which is shown in the results section. Based on this study, two GPR models are recommended for load forecasting, the Rational Quadratic GPR and the Exponential GPR and Exponential GPR as final model.

The need to apply halal management practices to non-food industries today is still merely seen as a necessity to meet the requirements of Islamic rules. Meanwhile, this approach has demonstrated that it can improve organizational efficacy in a variety of contexts. This study seeks to investigate the depth of halal principles implementation among leather industries and comes up with strategies for how small and medium-sized enterprises (SMEs) in the leather industry can use halal management practices to move toward halal certification and enhance its performance. An exploratory-descriptive approach was used to get the current state of halal practices among leather industry SMEs through interviews and survey questionnaires. Five stakeholders were interviewed in a semi-structured manner. A survey questionnaire was distributed to 127 SMEs in the leather industry center of Sukaregang, Garut, Indonesia. This paper discusses the key factors of halal implementation and determines which halal practices need more emphasis. The result showed that the current knowledge, awareness, and implementation of halal requirements among leather SMEs in Indonesia are still low. An action plan for the industry, authority, and supplier was provided. The implication of this research can contribute to the leather industry players that intent to implement halal management system effectively and stakeholders in making decision to accelerate halal certification process.

The research aimed to fill the research gap between the influence of financial know­ledge on financial management by using materialism as moderation. The sur­vey population was the number of populations based on the family card (KK) in the City of Denpasar. The sample in this study of 100 people from the community of Denpasar was determined based on simple random sampling. The analysis tech­nique used to test the hypothesis was Moderated Regression Analysis (MRA). Research results showed that financial knowledge was not sig­nificant to financial management behavior. Another finding was that materialism was unable to mode­rate the influence of financial knowledge on financial management behavior. Further research could develop this research by using other variables that theore­tically had an in­fluence on financial management behavior.

Abstract
Fast radio burst (FRB) source FRB 20180916B exhibits a 16.33-day periodicity in its burst activity. It is as of yet unclear what proposed mechanism produces the activity, but polarization information is a key diagnostic. Here we report on the polarization properties of 44 bursts from FRB 20180916B detected between 2018 December and 2021 December by CHIME/FRB, the FRB project on the Canadian Hydrogen Intensity Mapping Experiment. In contrast to previous observations, we find significant variations in the Faraday rotation measure (RM) of FRB 20180916B. Over the 9-month period 2021 April and 2021 December we observe an apparent secular increase in RM of ∼50 rad m−2 (a fractional change of over 40%) that is accompanied by a possible drift of the emitting band to lower frequencies. This interval displays very little variation in the dispersion measure (ΔDM ≲ 0.8 pc cm−3), which indicates that the observed RM evolution is likely produced from coherent changes in the Faraday-active medium’s magnetic field. Burst-to-burst RM variations appear unrelated to the activity cycle phase. The degree of linear polarization of our burst sample (≳80%) is consistent with the negligible depolarization expected for this source in the 400–800 MHz bandpass of CHIME. FRB 20180916B joins other repeating FRBs in displaying substantial RM evolution. This is consistent with the notion that repeater progenitors may be associated with young stellar populations by their preferential occupation of dynamic magnetized environments commonly found in supernova remnants, in pulsar wind nebulae, or near high-mass stellar companions.
Self-consistent Models of Y Dwarf Atmospheres with Water Clouds and Disequilibrium Chemistry
Authors: Lacy Brianna , Burrows Adam 
Published: June 2023

Abstract
Y dwarfs are the coolest spectral class of brown dwarf. They have effective temperatures less than 500 K, with the coolest detection as low as ∼250 K. They make up the low-mass tail of the star formation process, and are a valuable analog to the atmospheres of giant gaseous exoplanets in a temperature range that is difficult to observe. Understanding Y dwarf atmospheric compositions and processes will thus deepen our understanding of planet and star formation and provide a stepping stone toward characterizing cool exoplanets. Their spectra are shaped predominantly by gaseous water, methane, and ammonia. At the warmer end of the Y-dwarf temperature range, spectral signatures of disequilibrium carbon monoxide have been observed. Cooler Y dwarfs could host water clouds in their atmospheres. JWST spectral observations are anticipated to provide an unprecedented level of detail for these objects, and yet published self-consistent model grids do not accurately replicate even the existing Hubble Space Telescope and ground-based observations. In this work, we present a new suite of 1D radiative-convective equilibrium models to aid in the characterization of Y-dwarf atmospheres and spectra. We compute clear, cloudy, equilibrium chemistry and disequilibrium chemistry models, providing a comprehensive suite of models in support of the impending JWST era of panchromatic Y-dwarf characterization. Comparing these models against current observations, we find that disequilibrium CH4–CO and NH3–N2 chemistry and the presence of water clouds can bring models and observations into better, though still not complete, agreement.
Synchronizing the EMRIs and IMRIs in AGN Accretion Disks
Authors: Peng Peng , Chen Xian 
Published: June 2023

Abstract
Extreme-mass-ratio inspirals (EMRIs) and intermediate-mass-ratio inspirals (IMRIs) are important gravitational-wave (GW) sources for the Laser Interferometer Space Antenna (LISA). So far, their formation and evolution have been considered to be independent. However, recent theories suggest that stellar-mass black holes (sBHs) and intermediate-mass black hole (IMBHs) can coexist in the accretion disk of an active galactic nucleus (AGN), which indicates that EMRIs and IMRIs may form in the same place. Motivated by the fact that a gas giant migrating in a protoplanetary disk could trap planetesimals close to its orbit, in this paper we study a similar interaction between a gap-opening IMBH in an AGN disk and the sBHs surrounding it. We analyze the torques imposed on the sBHs by the disk and also by the IMBH, and show that the sBHs can be trapped by the IMBH if they are inside the orbit of the IMBH. We then implement the torques in our numerical simulations to study the migration of an outer IMBH and an inner sBH, which are both embedded in an AGN disk. We find that their migration is synchronized until they reach a distance of about 10 Schwarzschild radii from the central supermassive black hole, where the pair break up due to strong GW radiation. This result indicates that LISA may detect an EMRI and an IMRI within several years from the same AGN. This GW source will bring rich information about the formation and evolution of sBHs and IMBHs in AGNs.
