Authors: Цуприк В.Г.
Published: September 2023

Опыт возведения и эксплуатации стационарных морских нефтегазодобывающих платформ, также как и эксплуатации ледоколов однозначно показал, что такие объекты могут испытывать критические вибрации от пиковых нагрузок в процессе циклического разрушения ровных ледовых полей. В работе, на основании энергетической модели явления разрушения льда, как термодинамического процесса, с учетом его структуры и реологии, представлено математическое описание закономерностей формирования циклической ледовой нагрузки как динамического процесса нарастания напряженно-деформированного состояния локального объема льда и его разрушения. За основу разрабатываемой методологии взят энергетический критерий – критическое значение плотности удельной энергии упругой деформации единичного объема льда, вызывающее и интегрально учитывающее и описывающее все виды его механического разрушения. Этот критерий является «встроенным в структуру льда» природным регулятором возможного значения пика контактной силы и продолжительности цикла накопления упругой энергии в его объеме до разрушения, а также триггером, запускающим спонтанный нерегулируемый процесс динамического разрушения. В работе методологически обоснован алгоритм определения требующихся для моделирования динамического поведения основания платформы параметров циклической ледовой нагрузки

Experience in the construction and operation of stationary offshore oil and gas production platforms, as well as the operation of icebreakers, has clearly shown that such objects can experience critical vibrations from peak loads during the process of cyclic ice destruction. the paper, based on the energy model of the phenomenon of ice destruction as a thermodynamic process, taking into account its structure and rheology, there is a mathematical description of the regularities of the formation of a cyclic ice load as a dynamic process of increasing level the stress-strain state of ice local volume and its destruction .The developed methodology is based on the energy criterion – the critical value of the density of the specific elastic energy of deformation of a single volume of ice, which causes and integrally takes into account and describes all types of its mechanical destruction. This criterion is "built into the ice structure" a natural regulator of the possible value of the peak of the contact force and the duration of the cycle of accumulation of elastic energy in its volume until destruction, as well as a trigger that triggers a spontaneous unregulated process of dynamic destruction. The paper methodologically substantiates an algorithm for determining the parameters of cyclic ice load required for modeling the dynamic behavior of the platform

Published: September 2023

В последнее время усилилась деятельность человека в арктических и антарктических районах, а параллельно с этим возросли потребности в полном понимании процесса разрушения льда. Эти сведения имеют непосредственное применение ко многим задачам инженерной практики, и не только в полярных районах, но и в умеренных широтах применительно к зимним условиям. К числу таких задач относятся: разрушение ледяного покрова ледоколами или другими техническими средствами, устройство ледовых дорог и переправ, взлетно-посадочных полос и т.д. Многие проблемы, связанные со льдом, были решены и решаются в лабораторных условиях. Причем в последние годы доля лабораторных исследований постоянно увеличивается. Это происходит потому, что лабораторное оборудование все более и более усложняется, методика проведения экспериментов в каждой серии опытов при этом совершенствуется, а условия экспериментов поддаются более точному контролю. Однако с появлением систем автоматизированного проектирования, в состав которых включены модули для структурного анализа, стало возможным прогнозировать поведение изделий и конструкций в реальной среде путем виртуального тестирования CAD-моделей. Описанный способ моделирования напряженно-деформированного состояния ледяной пластины, разделенной трещинами, методом конечных элементов (линейный статический анализ) позволяет оценить несущую способность ледяного покрова без дорогостоящих экспериментальных исследований.

Recently, human activity in the Arctic and Antarctic regions has intensified, and in parallel with this, the need for a full understanding of the process of ice destruction has increased. This information is directly applicable to many tasks of engineering practice, and not only in polar regions, but also in temperate latitudes in relation to winter conditions. Such tasks include: the destruction of the ice cover by icebreakers or other technical means, the construction of ice roads and crossings, runways, etc. Many problems related to ice have been solved and are being solved in the laboratory. Moreover, in recent years, the share of laboratory research has been constantly increasing. This is because laboratory equipment is becoming more and more complicated, the method of conducting experiments in each series of experiments is being improved, and the experimental conditions are subject to more precise control. However, with the advent of computer-aided design systems, which include modules for structural analysis, it became possible to predict the behavior of products and structures in a real environment by virtual testing of CAD models. The described method of modeling the stress-strain state of an ice plate separated by cracks by the finite element method (linear static analysis) allows us to estimate the bearing capacity of the ice cover without expensive experimental studies.

Authors: N Supritha , Murthy M S Narasimha
Published: September 2023

Remotely sensed images, their classification and accuracy play a vital role in measuring a country’s scientific growth and technological development. Remote Sensing (RS) can be interpreted as a way of assessing the characteristics of a surface or an entity from a distance. This task of identifying and classifying datasets of RS images can be done using Convolutional Neural Network (CNN). For classifying images of large-scale areas, the traditional CNN approach produces coarse maps. For addressing this issue, Object based CNN method can be used. Classifying images with high spatial resolution can be done effectively using Object based image analysis. Deep learning methods offer the strength of auto learning the spatial features of an image. Object scale based adaptive CNN is a novel technique that can improve the accuracy of image classification of high spatial resolution images. For efficient RS image classification, a novel Deep learning approach called distributed CNN can be used which leads to enhanced accuracy of RS image classification. In this paper, three CNN models have been compared while considering the training time and efficiency to classify RS images as parameters of measure to assess the CNN models.

Authors: Nandhini E. , Sivaprakasam A.
Published: September 2023

An easy sensor-less scalar control algorithm is described in this article as a method for controlling the speed of an induction motor. For developing a closed-loop v/f control of the induction motor drive, a torque controller with PI is implemented. The torque command was estimated by utilizing the voltage command, the feedback current, and a torque estimator. Additionally, a torque reference was provided for the Torque PI controller. Considering this, the purpose of this work is to investigate the closed-loop PI-based torque control of an induction motor drive that applies DPWM. In addition to this, it provides a description of a PI-based closed-loop torque control that works in conjunction with v/f control and tries to discover the most effective method for driving an induction motor based on an examination of Total Harmonic Distortion (THD) and torque ripple. To evaluate the performance studies of open- and closed-loop strategies with DPWM techniques for induction motor driving, the MATLAB/Simulink environment has been deployed. Experimental results have been validated.

Islanding Detection in Distribution Generation using Active Method
Authors: Hariprasad B. , Sreenivasan G , Sujatha P
Published: September 2023

There are two techniques to ensure that renewable energy systems run continuously: on-grid and off-grid. In the first case the system can be managed in a network, in the second case it can be managed in a micro grid or island mode. Islanding means when a distributed generator (DG) keeps running even after there is no longer any external electricity. This situation can be dangerous for utility systems because it prevents equipment from connecting properly. Therefore, this paper proposes an active method for detecting island patterns at a given time. The use of DG installations such as photovoltaics can cause islanding detection issues. In addition, the number of DG sets in the power distribution system will affect the accuracy of island detection (ISD). On a test example DC power supply linked to a 415 V, 50 Hz network, the suggested solution was put into practice. In the MATLAB Simulink environment, the proposed method's efficacy was assessed. The proposed method is compared with existing active methods and shortens the detection time.
Implementation of Turbo Trellis Coding Modulation Scheme for Fading Channel
Authors: Goswami R.K. , Rao K. Srinivasa , Nambari Swathi
Published: September 2023

In the context of data communication, encountering fading channels can lead to errors occurring at the receiving end due to multipath propagation. To address this challenge, researchers have persistently worked towards developing Error Correction Schemes that effectively manage these errors and guarantee error-free data reception for the receiver. One area of focus lies in the implementation of Forward Error Correction Schemes directly at the transmitter end. Nonetheless, integrating error correction coding using these schemes comes with the drawback of increased bandwidth requirements since additional bits must be included to facilitate error correction. Fortunately, there exists a coding scheme known as Trellis Coded Modulation (TCM), which specifically tackles this concern. In the case of TCM, the modulation scheme has been chosen based on the rate of the convolutional coding scheme. Nevertheless, TCM has certain limitations when it comes to correcting a high number of errors, which prompted the emergence of Turbo Coding. Turbo Coding employs two coders at the transmitter, arranged either in a serial or parallel configuration, along with an appropriate decoder at the receiver. This paper introduces a Turbo Coding scheme design utilizing convolutional coders with a rate of 2/3, arranged in a serially concatenated configuration, resulting in an effective rate of 4/9. For preserving bandwidth, the Turbo Coding is applied to TCM scheme. Consequently, when employing the convolutional coding scheme with a rate of 2/3, the modulation scheme has to be 8-QAM. However, to maintain bandwidth after coding, when utilizing the Turbo coding scheme with a rate of 4/9, the modulation scheme is upgraded to 512-QAM. MATLAB simulations were conducted to evaluate the error correcting capabilities of the designed scheme compared to the convolutional coding scheme that uses the constituent convolutional encoder. The comparison has also been made with the uncoded data communication utilizing simple QPSK modulation scheme. The results indicate that under Rician fading channel conditions, the Turbo Trellis Coding Modulation Scheme provides an approximate gain of 5 dB compared to the convolutional coding scheme and approximately 8 dB gain compared to uncoded one.

Authors: Kathiriya Bhaveshkumar , Keraliya Divyesh
Published: September 2023

Spectrum scarcity problems can be resolved with the emerging communiqué technologies known as cognitive radio (CR). Cognitive radio networks (CRNs) will give mobile users greater bandwidth via wirelessly heterogeneity design and dynamic spectrum acquisition methods. The Cognitive Radio Mobile Ad-Hoc Network (CR-MANET) idea of Adaptive Routing a new network paradigm may be realized by using the functions of spectrum management to overcome such difficulties. Secondary users (SUs) have the freedom to opportunistically explore and make use of the open spaces on licensed channels. When a primary user (PU) interferes with a licensed channel, this forces the SU to leave it and switch to an open channel. Because of the constant channel switching those results, SUs degrades as a result. In this result recommends a number of channels, number of hop CRN that uses a fuzzy decision-making system that is genetically optimized for channel selection, channel switching, and spectrum allocation. According to study, the suggested architecture achieves higher PDR, throughput, latency, and transmission time than fuzzy and genetic algorithms. Through simulations the result demonstrates significant improvements in data rate performance, making it a promising solution for enhancing communication efficiency in cognitive radio networks.

Authors: Adupa Chakradhar , Ijjada Sreenivasarao
Published: September 2023

The resolution and conversion speed of an Analog to Digital converter (ADCs) strongly depends on how efficiently Sampling and Hold (S&H) circuit handles the amplitude skewing of the input analog signal. In this article, a novel S&H circuit has been proposed to handle the errors produced because of amplitude skewing. This circuit has two different paths for sampling and holds process and avoids the non-ideal effects seen in most of the recent literature. In portable applications, the restrictions on the available power and the importance of the quality of digital data are taken as a challenge. To make SAR-ADC more power efficient, all blocks should be designed with low-power techniques. Here, the sample and hold block need to be designed to the optimized power level, operate supply of 3.3V, implemented with SCL 0.18µm process, operating at a sampling rate of 10MHz with the power of 0.425mW.

Quantum Dot Cellular Automata is a Nano device efficient than other devices in nanotechnology for the last two decades. It is beneficial over Complementary Metal Oxide Semiconductor technology like high speed, low energy dissipation, high device density and high computation efficiency. To achieve further optimization different methods like simplifications in Boolean expressions, tile method, clocking scheme, cell placement, cell arrangement, novel input techniques, etc., are in use. These methods improve the performance metrics in terms of QCA Cells, total circuit area, delay in output, power consumption, and coplanar or multilayer layout. This paper is about the novel NOT gate layout designed with efficient parameters compared to existing NOT gates except area parameters with analysis and XOR gate and multiplexer circuits. The novel gate provides an improvement of 55% in the number of cells, polarization raised by 0.33, and an 80.77% improvement in total area. These circuits illustrate further scope in QCA circuit design efficiently. XOR circuit shows area reduction up to 0.006 μm2 with 0.5 clock cycle delay. Further optimization in XOR parameters and with this novel NOT gate researchers can optimize parameters to bring revolution and digitalization.
A New Soft Computing Fuzzy Logic Frequency Regulation Scheme for Two Area Hybrid Power Systems
Authors: Nireekshana Namburi , Ramachandran R. , Narayana G. V.
Published: September 2023

Modern renewable energy power system designs provide significant application benefits, but they also produce losses. The total generation, total load demand, and system losses must be balanced in order for this structured power system to operate reliably. The actual and reactive power balances are disturbed as a result of changes in load demand. System frequency and tie line interchange power deviate from their planned values as a result of this. A high system frequency deviation can cause the system to crash. In that case, multiple connect area systems use intelligent load frequency control techniques to deliver dependable and high-quality frequency and tie line power flow. Here, a standalone hybrid power system is taken into consideration, with generated power and frequency being controlled intelligently. In addition to the unpredictable nature of the wind, frequent adjustments in the load profile can produce sizeable and detrimental power variations. The output power of such renewable sources may fluctuate to the point that it causes significant frequency and voltage changes in the grid. An intelligent approach recently proposed to address the load frequency control (LFC) issue of an interconnected power system is known as fuzzy logic PID controller (FLPIDC). Standard proportional integral derivative (PID) controllers are used to control each section of the system.

Advocates in carrying out their profession are under the protection of laws, statutes and codes of ethics, which cannot be prosecuted before a court, either civil or criminal, as long as they have good faith in defending the interests of their clients. However, in practice, many Advocates are caught in criminal cases in carrying out their professional duties. The purpose of this study is to analyze and find out the characteristics of good faith referred to in article 16 of Law Number 18 of 2003 concerning Advocates in terms of law enforcement and legal protection for the advocate profession and criminal liability for the actions of advocates in carrying out their professional duties without going through the mechanism of examining the Code of Ethics. . The theory used to analyze is law enforcement theory, legal protection theory, and criminal responsibility theory. The writing method used is normative writing method, by analyzing a legal issue through laws and regulations, literature, and other reference materials. The results of this study are that the work of a legal advisor is a work of trust in good faith to rectify the problems faced by clients whose existence is regulated and protected by law. The criminal responsibility of an advocate who commits a crime in carrying out his profession must be seen from the mistakes made by the advocate so that he is seen as having committed an act that meets the elements of a crime which must be proven first through an examination of the code of ethics. The government and/or legislators must pay more attention to and scrutinize the formation of statutory regulations so that there are no overlapping rules and so that one law does not conflict with another. As well as to strengthen the profession, it is hoped that there will be a need for stricter and more precise rules that can be used as a legal umbrella in professional life.

Published: September 2023

A trademark which comprises a single color or a combination of colors has become the subject of registration in Korea since 2007. Color marks is recognized as one of the non-traditional mark. The concern that a color can be monopolized due to the effect of trademark protection and no one else use the mark results in the fact that there are still only a few examples of trademark registration of color marks. It can be said that it is important to establish the standard for protection under what conditions prescribes the protection of color marks. In particular, the question of distinctiveness, which is a basic requirement for trademark protection, it is considered that colors cannot be inherently distinctive in principle, and must be acquired secondary meaning through use. It is difficult to assume that colors are used alone, and there is a difficulty in that colors should be regarded as having independent discrimination when used together with letters and/or symbols. A consumer survey can be an effective for measuring acquired distinctiveness, but must be taken to ensure reliable results. Functionality doctrine is also important requirements for color marks protection, and not only traditional utilitarian functionality but also aesthetic functionality needs to be reviewed.
Meaning of “change in the perspective of criminal law”, which is the standard for changing laws and regulations to which Article 1 (2) of the Criminal Act applies - About: Sentence 2020 Do16420 Decision on December 22, 2022 -

Recently, the Supreme Court has decided that the change of laws and regulations referred to in Article 1 (2) of the Criminal Act and Article 326 (4) of the Criminal Procedure Act differs from the clear concept of the text, and the applicable laws and regulations should be different depending on whether the change is based on reflective consideration.
It is difficult to find a reason for doing so, and if the position of the motive theory that considers the intention of the legislator is maintained, reducing the interpretation of Article 1 (2) of the Criminal Act and Article 326 (4) of the Criminal Procedure Act, which is favorable to the accused, will eventually be unfavorable to the accused. Based on the fact that the scope of punishment could be expanded in this direction, the previous Supreme Court ruling was reversed and the attitude changed.
Unless the legislature provides a transitional provision stipulating that criminal punishment for violations of previous laws and regulations shall be maintained even after the change of laws and statutes, the Supreme Court shall determine whether the criminal statutes themselves or the statutes authorized or delegated by them concerning the formation and punishment of crimes If the change does not constitute a crime or the sentence is lightened, in principle, Article 1 (2) of the Criminal Act and Article 326 (4) of the Criminal Procedure Act shall be applied regardless of whether the statute was changed based on 'reflective consideration'.
As the Supreme Court recently changed the position of the previous case and seems to have derived the concept of “change in criminal legal perspective” as a new criterion for applying the trial law, it is necessary to examine what the conceptual sign of change in criminal legal perspective means.
A Review on the Inevitable Reasons under article 720 of the Civil Act: Regarding the Claim for the Dissolution in a Two-Person Partnership

Compared to foreign legislative precedents, Korean civil act takes a legislative attitude that prioritizes a general partnership's corporate identity over the autonomy of a partnership. And the Supreme Court of Korea’s judgments are in a position to emphasize the necessity of the collective nature or existence of a partnership. Under these legal regulations, even if a two-person partnership reaches a situation in which trust is significantly impaired, if the problem can be solved by the withdrawal of a single partner, the court allows the remaining partner to continue the business. It would be reasonable to interpret the dissolution claim by limiting the 'inevitable reasons' as much as possible.
In addition, even if the relationship of trust between partners is damaged to some extent, when considering all circumstances related to the cooperative business, it could not be significantly difficult to achieve the partnership’s business. In such a situation, it is more in line with the attitude of our civil law rules to judge whether or not it falls under 'inevitable reasons' by prioritizing the continuation of business in view of the public interest.
On the other hand, if it is difficult to achieve the purpose of the partnership business or if the relationship of trust between partners is destroyed to the extent that it is difficult to recover, a partner at fault may also seek the dissolution of a partnership. However, in judging inevitable reasons under §720 of the Civil Act, if dissolution of a partnership through a reasonable balance of interests is against the rule of good faith, it would be appropriate not to allow dissolution.
Mucormycosis as a Rare Infection in Lower Limb Necrotizing Fasciitis: A Case Report
Authors: Abdessamad Hilal , Mokhbat Jacques
Published: September 2023

Introduction: Necrotizing fasciitis is a severe, life-threatening infection that can be fatal and rapidly progressive. It is usually caused by polymicrobial infection, monomicrobial infection by group-B streptococci (GBS) or staphylococci, or by anaerobes like Clostridium difficile that presents as a gas gangrene or rarely by fungi. Fungal infections, though found in diabetic foot ulcers, remain extremely rare agents in necrotizing fasciitis, often causing severe morbidity and higher mortality than regular bacterial infections. Though severe, these infections are not often late to diagnose and very few reports exist citing their presence. With our case report, we present another rare manifestation of Mucormycosis in a foot wound.
Case Report: We present a 57-year-old diabetic male patient who presented with a rapidly progressing very painful right foot ulcer, with high-grade fever and fatigue that did not respond to surgical intervention and treatment with broad-spectrum antibiotics. Mucormycosis species were identified in wound cultures. The patient then underwent an amputation and was treated with liposomal Amphotericin B.
Conclusion: This report aims to further highlight that virulent fungal infections, especially mucormycosis, should be considered when suspecting or diagnosing necrotizing fasciitis. An extensive review of the literature with our newly added case would serve as an eye-opener on this pathogen in the setting of difficult-to-treat necrotizing fasciitis.

Antimicrobial agents are supposed to be the most important means for treating bacterial infections. The use of steroidal and non-steroidal drugs is leading the disturbance of the normal microflora of gastrointestinal tract. This interference may result in abnormality of natural defence mechanism which is due to the colonic microbial ecosystem, making the host resistant to infections caused by commensal microorganisms and nosocomial pathogens. The agar well diffusion assay method was performed to observe the zones of inhibition caused by antimicrobial agents. Up to 25 antimicrobial drugs were used and out of 25 drugs, five antimicrobial drugs gave huge zones of inhibition.
