Authors: Ketan Kalke  , Dr. Bhumeshwar Patle  
Published: August 2023

Building high-performance motor drives is vital for industrial uses. A high-performance motor drive system must be quick in terms of dynamic speed order monitoring and load regulation. The motor controllers can provide system protection by regulating or limiting torque, protecting against overloads, and safeguarding against mistakes. Many motor controllers include logic for managing applications as well as additional features like data recording and data collecting. The purpose is to study various tuning techniques for motor speed controllers using Artificial intelligence. The controllers such as proportional-integral (PI) controller and proportional integral derivative (PID) controller have been considered here. Most frequently used Artificial intelligence (AI) methods such as Artificial Neural Networks (ANN), Fuzzy logic controller (FLC), Genetic Algorithm (GA), Bat Algorithm, Adaptive Tabu Search (ATS), Ant Colony Optimization (ACO), Ziegler and Nichols (ZN) Algorithm are considered by their decision-making capability. In the proposed work a rigorous literature review is done for analyzing the performance of AI-based controllers. This will help other researchers to understand various aspects of the said controllers, particularly the technology involved. In-depth review and application of AI controllers are highlighted using various charts and graphs for easy understanding.

Proses Perhitungan Harga Pokok Produksi Berdasarkan Full Costing Sebagai Dasar Dalam Menentukan Harga Jual Pada CV Albaik Herbal Indonesia
Authors: Amanda Shanya , Jasmadeti Jasmadeti 
Published: August 2023

Penetapan biaya produksi sangat penting karena meningkatkan persaingan antar perusahaan dalam menghasilkan produk yang berkualitas dengan harga yang kompetitif. Perhitungan harga pokok produksi (HPP) merupakan hal yang penting untuk diperhatikan dalam menentukan harga jual produk. Perhitungan HPP yang tepat dan akurat merupakan hal yang harus dilakukan oleh setiap perusahaan, karena tanpa adanya perhitungan HPP yang tepat dan akurat, perusahaan manufaktur yang bersangkutan akan mengalami masalah dalam menentukan harga jual suatu produk. Tujuan penelitian ini adalah untuk menganalisis bagaimana pengalokasian dan perhitungan harga pokok produksi dalam menentukan harga jual kapsul pelangsing dengan metode perusahaan dan metode full costing. Hasil penelitian ini menunjukan terdapat kelemahan dalam perhitungan harga pokok produksi dalam menentukan harga jual perusahaan yaitu kalkulasi harga jual yang dilakukan perusahaan lebih rendah dari pada harga jual setelah dievaluasi. Menurut perusahaan harga jual kapsul pelangsing sebesar Rp 29.334/pcs, sedangkan harga jual dengan metode full costing sebesar Rp 30.014/pcs, hal ini disebabkan karena perusahaan tidak membebankan biaya bahan baku seperti gas, biaya air, dan biaya tenaga kerja tidak langsung. Metode penetapan full costing adalah suatu metode penentuan harga pokok produksi yang menghitung semua unsur dari biaya produksi yang terdiri dari biaya bahan baku, tenaga kerja langsung, tenaga kerja tidak langsung, biaya overhead pabrik, baik biaya tetap maupun biaya variabel. Harga jual dapat diperoleh dari harga pokok produksi ditambah keuntungan yang diharapkan. Hasil penelitian menyatakan bahwa perhitungan harga pokok produksi terdapat selisih yang mempengaruhi harga jual.

Development of competitive businesses have triggered changes in the various methods of business management to streamline labor costs, overhead costs and raw material costs in improving product quality. Manufacturing companies are in a period of dynamic transformation that requires the manufacturers to always expand its business to survive and have strong competitiveness in addition to the company must have a strategy for its business organization, strategies must be developed by the company in addition to developing the company's products also must develop the data processing. Hopefully, by the system of all the activities of the company can be run according to plan and to minimize deviations or errors that occur which could harm the company. Object of research chosen by the authors is the company CV Surya Pratama Gemilang, a medium-sized manufacturing company that produces a variety of bacterial decomposition and laboratory equipment. The company has a systematic record system and computerized production and there are some systems that are still made manually as demandfor raw materials from the production to the warehouse with a wane sometimes only just though the procedure had to use a memo for taking raw materials from the warehouse. In doing production company CV Surya Pratama Gemilang processing raw materials into finished products based on processes that make the production process according to the requirement or determination of the bam, so when the warehouse inventory is less than the policysetting in the warehouse, the company started production to meet the needs of the provisions in the warehouse. From the nature of the production process suitable production cost calculation is based on the cost method (Process Costing).

What’s the Difference? The Potential for Convolutional Neural Networks for Transient Detection without Template Subtraction
Authors: Acero-Cuellar Tatiana , Bianco Federica , Dobler Gregory , Sako Masao , Qu Helen ,   The LSST Dark Energy Science Collaboration
Published: August 2023

Abstract
We present a study of the potential for convolutional neural networks (CNNs) to enable separation of astrophysical transients from image artifacts, a task known as “real–bogus” classification, without requiring a template-subtracted (or difference) image, which requires a computationally expensive process to generate, involving image matching on small spatial scales in large volumes of data. Using data from the Dark Energy Survey, we explore the use of CNNs to (1) automate the real–bogus classification and (2) reduce the computational costs of transient discovery. We compare the efficiency of two CNNs with similar architectures, one that uses “image triplets” (templates, search, and difference image) and one that takes as input the template and search only. We measure the decrease in efficiency associated with the loss of information in input, finding that the testing accuracy is reduced from ∼96% to ∼91.1%. We further investigate how the latter model learns the required information from the template and search by exploring the saliency maps. Our work (1) confirms that CNNs are excellent models for real–bogus classification that rely exclusively on the imaging data and require no feature engineering task and (2) demonstrates that high-accuracy (>90%) models can be built without the need to construct difference images, but some accuracy is lost. Because, once trained, neural networks can generate predictions at minimal computational costs, we argue that future implementations of this methodology could dramatically reduce the computational costs in the detection of transients in synoptic surveys like Rubin Observatory's Legacy Survey of Space and Time by bypassing the difference image analysis entirely.
Modeling Apsidal Motion in Eclipsing Binaries Using ELC
Authors: Dimoff Alexander J. , Orosz Jerome A. 
Published: August 2023

Abstract
Apsidal motion is the precession of the line of apsides in the orbit of a binary star due to perturbations from General Relativity (GR), tides, or third-body interactions. The rate of precession due to tidal effects depends on the interior structures of the stars, and as a result, binaries in which this precession occurs are of great interest. Apsidal motion is observed through the analysis of eclipse times, which reveal small changes in the average interval between successive primary and secondary eclipses, taking all available observed times of eclipse and yielding an estimate of the apsidal rate. Given that this is a single observed quantity, various degeneracies are unavoidably present. Ideally, one would have a model that predicts eclipse times given the orbital and stellar parameters. These parameters for a given binary could then be computed using least squares, provided a suitably large number of eclipse times. Here we use the eclipsing light curve (ELC) program as such a model. The Newtonian equations of motion with additional force terms accounting for GR contributions and tidal distortions are integrated, yielding precise sky positions as a function of time. Times of mid-eclipse and instantaneous orbital elements are computed as a function of time. In this paper, we outline the method and compare numerically computed apsidal rates with standard formulae using a set of 15 binaries based on real systems. For our simulated systems, the derived apsidal rates agree with the standard formula.
A Surprising Lack of Metallicity Evolution with Redshift in the Long Gamma-Ray Burst Host Galaxy Population
Authors: Graham J. F. , Schady P. , Fruchter A. S. 
Published: August 2023

Abstract
The number of long-duration gamma-ray burst (LGRB) host galaxies with measured metallicities and host masses has expanded sufficiently to investigate how the distributions of these properties change with redshift. Using the combined host galaxy metallicity sample from Graham & Fruchter and Krühler et al., we find a surprising lack of evolution in the LGRB metallicity distribution across different redshifts. In particular, the fraction of LGRB hosts with relatively high metallicity (12+log(O/H) ≥ 8.4) remains essentially constant out to z = 2.5. This result is at odds with the evolution in the mass–metallicity relation of typical galaxies, which become progressively more metal poor with increasing redshift. A similar result is found when converting the LGRB host galaxy mass distribution taken from the Swift GRB Host Galaxy Legacy Survey (SHOALS) sample to a corresponding metallicity distribution by applying a redshift-dependent mass–metallicity relation. The SHOALS sample is compiled using an unbiased selection function implying that the observed lack of evolution in the host galaxy high-metallicity distribution is not caused by selection effects. However, the LGRB host galaxy metallicities estimated from the stellar mass are typically a quarter dex higher at all redshifts than the metallicity we measure spectroscopically. This implies that using mass–metallicity relationships to estimate host metallicities will thus produce a substantial systematic bias.
Evidence for Misalignment between Debris Disks and Their Host Stars
Authors: Hurt Spencer A. , MacGregor Meredith A. 
Published: August 2023

Abstract
We place lower limits on the obliquities between debris disks and their host stars for 31 systems by comparing their disk and stellar inclinations. While previous studies did not find evidence for misalignment, we identify six systems with minimum obliquities falling between ∼30°and 60°, indicating that debris disks can be significantly misaligned with their stars. These high-obliquity systems span a wide range of stellar parameters with spectral types K through A. Previous works have argued that stars with masses below 1.2 M
⊙ (spectral types of ∼F6) have magnetic fields strong enough to realign their rotation axes with the surrounding disk via magnetic warping; given that we observe high obliquities for relatively low-mass stars, magnetic warping alone is likely not responsible for the observed misalignments. Yet, chaotic accretion is expected to result in misalignments of ∼20° at most and cannot explain the larger obliquities found in this work. While it remains unclear how primordial misalignment might occur and what role it plays in determining the spin–orbit alignment of planets, future work expanding this sample is critical toward understanding the mechanisms that shape these high-obliquity systems.
Cosmological Simulations of Galaxy Groups and Clusters. III. Constraining Quasar Feedback Models with the Atacama Large Millimeter Array
Authors: Chakraborty Avinanda , Chatterjee Suchetana , Lacy Mark , Roy Soumya , Roy Samrat , Kar Chowdhury Rudrani 
Published: August 2023

Abstract
The thermal Sunyaev–Zeldovich (SZ) effect serves as a direct potential probe of the energetic outflows from quasars that are responsible for heating the intergalactic medium. In this work, we use the GIZMO meshless finite mass hydrodynamic cosmological simulation SIMBA, which includes different prescriptions for quasar feedback, to compute the SZ effect arising from different feedback modes. From these theoretical simulations, we perform mock observations of the Atacama Large Millimeter Array (ALMA) in four bands (320, 135, 100, and 42 GHz) to characterize the feasibility of direct detection of the quasar SZ signal. Our results show that for all the systems we get an enhancement of the SZ signal, when there is radiative feedback, while the signal gets suppressed when the jet mode of feedback is introduced in the simulations. Our mock ALMA maps reveal that, with the current prescription of jet feedback, the signal goes below the detection threshold of ALMA. We also find that the signal is higher for high redshift systems, making it possible for ALMA and cross SZ-X-ray studies to disentangle the varying modes of quasar feedback and their relative importance in the cosmological context.
Disk Wind–Driven Expanding Radio-emitting Shell in Tidal Disruption Events
Authors: Hayasaki Kimitake , Yamazaki Ryo 
Published: August 2023

Abstract
We study the evolution of a nonrelativistically expanding thin shell in radio-emitting tidal disruption events (TDEs) based on a one-dimensional spherically symmetric model considering the effect of both a time-dependent mass-loss rate of the disk wind and the ambient mass distribution. The analytical solutions are derived in two extreme limits; one is the approximate solution near the origin in the form of the Taylor series, and the other is the asymptotic solution in which the ambient matter is dominant far away from the origin. Our numerical solutions are confirmed to agree with the respective analytical solutions. We find that no simple power law of the time solution exists in early to middle times because the mass-loss rate varies over time, affecting the shell dynamics. We also discuss the application of our model to the observed radio-emitting TDE, AT 2019dsg.
Confronting a Thin Disk-wind Launching Mechanism of Broad-line Emission in Active Galactic Nuclei with GRAVITY Observations of Quasar 3C 273

Abstract
Quasars show a remarkable degree of atomic emission-line broadening, an observational feature which, in conjunction with a radial distance estimate for this emission from the nucleus, is often used to infer the mass of the central supermassive black hole. The radius estimate depends on the structure and kinematics of this so-called broad-line region, which is often modeled as a set of discrete emitting clouds. Here, we test an alternative kinematic disk-wind model of optically thick line emission originating from a geometrically thin accretion disk under Keplerian rotation around a supermassive black hole. We use this model to calculate broad emission-line profiles and interferometric phases to compare to GRAVITY data and previously published cloud modeling results. While we show that such a model can provide a statistically satisfactory fit to GRAVITY data for quasar 3C 273, we disfavor it as it requires 3C 273 be observed at high inclination, which observations of the radio jet orientation do not support.
