Показано, что процессы информационного обмена в сложных распределенных структурах предполагают соответствующие механизмы управления на основе должного описания, учитывающего различные последовательности формирования компонентов сообщений, которые целесообразно описывать на основе потоковых моделей распределенных вычислений, определяющих общий подход для решения задач анализа и синтеза функциональной архитектуры в плоскости свойств, количественной оценки вероятностновременных параметров процесса информационного обмена с учетом параметров процедур, реализуемых на различных уровнях соответствующими протоколами, а также определяющих общий характер взаимосвязей с учетом параметров процедур.

It is shown that the processes of information exchange on complex distributed structures presume relevant management mechanisms based on proper description, take into consideration the diverse sequences of the formation of message components that are appropriate to describe on the basis of streaming models of distributed computing that determine a common approach to solve issues of analysis and synthesis of functional architecture in property planes, quantitative evaluation of the probabilitytime parameters of the process of information exchange taking into account the parameters of the procedures implemented at various layers by the relevant protocols, as well as determining the general character of interrelations taking into account the procedure parameters.

Published: September 2024

Одним из важнейших узлов любого отопительного котла является первичный теплообменник, в котором тепловая энергия от горячих продуктов сгорания топлива передается теплоносителю. Именно от характеристик этого компонента во многом зависят эксплуатационные характеристики оборудования: его КПД и экономичность, срок службы и стоимость. В условиях ожесточенной конкуренции между производителями все узлы бытовых котлов имеют тенденцию к упрощению конструкции и удешевлению. Вместе с тем существует стабильный спрос на газовые премиальные котлы с медным теплообменником. Почему потребители выбирают их, несмотря на высокую цену, и в чем преимущества меди как конструкционного материала

Authors: Кан Л. , Карпенко А.П.
Published: September 2024

В работе предложены модификации алгоритма глобальной оптимизации PSO, который основан на каноническом алгоритме роя частиц PSO. Алгоритм PSO предназначен для решения задач групповой робототехники, сводящихся к локализации глобального экстремума некоторой скалярной целевой функции, в условиях, когда в области поиска отсутствуют препятствия движению роботов. Предложенные в данной работе модификации алгоритма PSO учитывают возможность того, что такие препятствий имеются. Целью работы является изучение влияния препятствий на эффективность модифицированного алгоритма PSO. Рассматриваем два варианта задачи: имеется априорная информация о расположениях и размерах препятствий указанная априорная информация отсутствует.

The paper proposed modifications of the PSO global optimization algorithm, which is based on the particle swarm canonical algorithm (PSO). The PSO algorithm is intended for solving group robotics problems that reduce to the localization of the global extremum of a certain scalar objective function under conditions where there are no obstacles to the movement of robots. The modifications of the PSO algorithm proposed in this paper take into account the possibility that such obstacles exist. The aim of the work is to study the effect of obstacles on the efficiency of the modified PSO algorithm. We consider two variants of the problem: there is a priori information about the locations and sizes of obstacles the specified prior information is missing.

Рассмотрена задача о нестационарном теплообмене в нагнетательной скважине, окруженной однородной ортотропной средой. Задача осложнена учетом радиального профиля скорости закачиваемой жидкости. Теплообмен на границе скважина окружающий массив задан с использованием условий сопряжения. Приведены аналитические асимптотические решения рассматриваемой задачи для средней по сечению температуры и для ее радиального распределения. С использованием вычислительного эксперимента показано, что диапазон инверсии и диапазон температурного сигнала флюида увеличиваются с увеличением приемистости нагнетательной скважины.

The problem of unsteady heat exchange in an injection well surrounded by a homogeneous orthotropic medium is considered. The task is complicated by taking into account the radial velocity profile of the injected fluid. Heat transfer at the wellmedia boundary is specified using interface conditions. Analytical asymptotic solutions of the problem under consideration are given for the average over the cross section temperature and for its radial distribution. Using a computational experiment, it was shown that the inversion range and the temperature range of the fluid signal increase with increasing receptivity of the injection well.

Prospects for automated cars to decrease transportation energy
Authors: РАГИМОВ Э.А.
Published: September 2024

Использование энергии на транспорте и выбросы углерода продолжают расти, но и то, и другое необходимо резко сократить. Традиционные предлагаемые решения, все уже использовавшиеся до некоторой степени, включают переход на низкоуглеродистое транспортное топливо, значительные улучшения в эффективности использования топлива для транспортных средств и модальный сдвиг. Однако их влияние было незначительным. Вместо этого эта статья исследует, в какой степени полностью автоматизированные транспортные средства могут способствовать экологической устойчивости глобального пассажирского транспорта. Было обнаружено, что полностью автоматизированные транспортные средства приводят либо к увеличению, либо, в лучшем случае, к незначительному сокращению потребления энергии и выбросов парниковых газов, и поэтому в лучшем случае будут иметь минимальное использование для сокращения выбросов в обычном мире. Вопервых, причина этого вывода заключается в том, что их потенциально более низкие затраты времени и денег могут привести к увеличению поездок на транспортных средствах, что компенсирует любое повышение энергоэффективности, а вовторых, что они сталкиваются с серьезными проблемами, которые могут задержать или даже предотвратить их широкое внедрение.

Transport energy use and carbon emissions continue to grow, but both need to be drastically reduced. Traditional proposed solutions, all of which have already been used to some extent, include switching to lowcarbon vehicle fuels, significant improvements in vehicle fuel efficiency and modal shift. However, their impact was negligible. Instead, this article explores the extent to which fully automated vehicles can contribute to the environmental sustainability of global passenger transport. It has been found that fully automated vehicles lead either to an increase or, at best, to a slight reduction in energy consumption and greenhouse gas emissions, and therefore, at best, will have minimal use to reduce emissions in the ordinary world. Firstly, the reason for this conclusion is that their potentially lower costs of time and money can lead to increased travel by vehicles, which compensates for any increase in energy efficiency, and secondly, that they face serious problems that may delay or even prevent their widespread adoption.
Modeling of thermal processes in measuring transducer for monitoring of paraffin deposits in oil pipelines

Published: September 2024

Рассматривается измерительный преобразователь для контроля парафиновых отложений в трубах нефтепроводов, основанный на зависимости измеряемых параметров процессов теплопередачи от толщины слоя отложений. Для повышения чувствительности преобразователя предложено наряду с использованием основного кольцевого нагревателя, охватывающего трубу, применять идентичные ему нагревателитермобарьеры, которые устанавливаются на некотором расстоянии от основного нагревателя и служат для создания эквитермальных зон, которые изменяют градиент температур и замедляют растекание тепла от основного нагревателя вдоль трубы. В результате гораздо большая часть тепла направляется внутрь парафинового слоя, влияние которого на показания датчика температуры заметно возрастает. Термодатчики расположены на трубе непосредственно под основным нагревателем. Выполнено компьютерное моделирование тепловых процессов, происходящих в предложенном преобразователе, в программной среде ELCUT. Обсуждаются его результаты. Выявлено, что наиболее предпочтительными измеряемыми параметрами являются максимальная для фазы нагревания относительная температура, соответствующая термодинамическому балансу, а также относительная температура, измеренная в момент времени 1/10 длительности фазы остывания.

The measuring transducer for monitoring of paraffin deposits in oil pipelines is considered. It is based on dependency of measured heat transfer parameters from paraffin layer thickness. The transducer includes a ringshaped heater clasping the pipe. For improving transducer sensitivity it was proposed to use additional heaters which are identical to the main heater. They are positioned on both sides of the main one and serve as thermal barriers forming equithermal zones in the pipe wall and changing the temperature gradient. As a result, heat losses in the steel pipe decrease and thermal flow from the heater is redirected into the layer of paraffin deposit. It makes the transducers output parameters more dependent on the thickness of paraffin sediments. Temperature sensors are placed on the pipe outer surface just under the main heater. The modeling of thermal process in the proposed transducer has been carrying out within the ELCUT program environment. The results of modeling are discussed. It was found out that the most preferable process parameters for measuring are maximal relative temperature for the heating stage when the thermodynamic balance is being achieved and relative temperature for the moment corresponding to 1/10 of cooling stage duration.
Data Efficiency of Classification Strategies for Chemical and Materials Design
Authors: Gallagher Quinn , Webb Michael
Published: September 2024

Active learning and design-build-test-learn strategies are increasingly employed to accelerate materials discovery and characterization. Many data-driven materials design campaigns target solutions within constrained domains such as synthesizability, stability, solubility, recyclability, and toxicity. Lack of knowledge about these constraints can hinder design efficiency by producing samples that fail to meet required thresholds. Acquiring this knowledge during the design campaign is inefficient, and effective classification of common materials constraints transcends specific design objectives. However, there is no consensus on the most data-efficient algorithm for classifying whether a material satisfies a constraint. To address this gap, we comprehensively compare the performance of 100 strategies designed to classify chemical and materials behavior. Performance is assessed across 31 classification tasks sourced from the literature in chemical and materials science. From these results, we recommend best practices for building data-efficient classifiers, showing the neural network- and random forest-based active learning algorithms are most efficient across tasks. We also show that classification task complexity can be quantified based on task metafeatures, most notably the noise-to-signal ratio. Overall, this work provides a comprehensive survey of data-efficient classification strategies, identifies attributes of top-performing strategies, and suggests avenues for further study.
Large-Area Bilayer Organic Solar Cells: Manipulating Interface and Morphology with Solvent Drenched Slot-Die Coating

Published: September 2024

Organic photovoltaics (OPVs) have emerged as a promising technology for renewable energy production. However, their stability and performance depend on the morphology and roughness of the interface between donor and acceptor layers. In this study, we investigated the transport properties and degradation mechanisms of inverted bilayer solar cells based on P3HT using dark current measurements and capacitance spectroscopy. Our study shows that the molecular orientation and intermixing of the donor and acceptor layers can be regulated using a solvent-drenching slot-die coating, leading to interfaces with varying levels of smoothness. We demonstrate that devices with smooth interfaces exhibit higher open-circuit voltages, lower radiative and non radiative losses, and lower defect densities than those with rough interfaces. Moreover, we reveal the role of tunnelling-enhanced recombination in limiting the device performance and stability. Our findings provide insights into the design and optimization of bilayer OPV devices with a high interface quality and low voltage loss.

Single-walled carbon nanotubes (SWCNTs) exhibit non-photobleaching, near-infrared (NIR) fluorescence suitable for bioimaging applications. In particular, SWCNT fluorescence quenching induced by biopolymer dispersants facilitates flexible design of molecular nanosensors, yet challenges remain in analyte selectivity and lack of rational design strategies. A sought-after alternative to haphazard molecular modulation of SWCNT-based fluorescence is to couple the movement of a quencher to the SWCNT surface, enabling fluorescence energy transfer to modulate molecular recognition with high selectivity. This study presents the rational design of SWCNT-based nanosensors that leverages the unique properties of methylene blue (MB)-proximity mediated fluorescence quenching. MB-SWCNT based nanosensors exhibit 1- stability in redox environments and 2- analyte-specific displacement-driven fluorescence modulation. By designing hybridization-induced displacement of MB-conjugated ssDNA from the SWCNT surface, we calculate that SWCNT fluorescence modulation can occur within a 6.8 nm fluorescence resonance energy transfer distance from the SWCNT surface, and develop a robust and versatile platform to synthesize oligonucleotide nanosensors with tunable ΔF/F0 of up to 150%. Building upon this strategy, we developed four distinct nanosensors capable of selectively detecting tobacco mosaic virus (TMV) viral RNA fragments, which successfully differentiated TMV-infected plants from mock controls. Finally, we demonstrate the potential expansion of our design to target a wider scope of biomolecules using the biotin-avidin system as a model. By attaching biotin to MB-conjugated ssDNA, we enabled selective and robust responses to biotin-binding proteins through the same MB displacement mechanism as our oligonucleotide nanosensors. Therefore, we herein present a generalizable platform that enables rational engineering of SWCNT NIR fluorescence intensity through MB distance-dependent fluorescence energy transfer, overcoming the intrinsic selectivity challenges of current SWCNT nanosensors.
Tracking Whale Calls in the Lower St. Lawrence Seaway at Land Seismometers

Published: September 2024

The Lower St. Lawrence Seaway (LSLS) is critical to Canada’s economy both as part of a major marine shipping corridor and a site of intensive fishing. Every year, fin whales and blue whales frequent the LSLS feeding ground. Understanding the mechanisms driving whale habitat usage is key for making informed decisions on shipping and fishing, reducing whale collision risks and mitigating noise pollution. We detect whales in the LSLS with land seismometers by using a method that relies on the intervals of the regularly repeating low frequency calls. The resulting catalogue contains 14,076 fin whale detections and 3,739 blue whale detections between February 2020 and January 2022. These detections follow the overall pattern of hydrophones, with most detections from fall to early winter in the Estuary and until mid-winter/spring in the Gulf. High detection rates in the Northwest Gulf throughout the winter months demonstrate that this region is potentially utilized year-round. This labelled catalogue may be suitable for developing a deep learning-based whale call detection algorithm. Making use of seismometers and deep learning can increase whale monitoring coverage within the LSLS and elsewhere.
Constituent Power and the Challenge to Parliamentary Sovereignty
Authors:   , Schlamowitz Marcel
Published: September 2024

"This thesis provides an in-depth analysis of the doctrine of parliamentary sovereignty emphasizing its legal and constitutional dimensions by exploring recent developments in constitutional jurisprudence. The thesis discusses the doctrine’s presence in countries with unwritten constitutions such as the United Kingdom, New Zealand, and Israel, and contrasts it with jurisdictions that have written constitutions, which typically limit legislative power, where they question the extent of parliamentary sovereignty as expressed by different legal scholars such as Blackstone and Dicey. The thesis not only illustrates how parliamentary sovereignty manifests differently across various legal systems, influenced by historical, cultural, and political contexts but also dissects the theoretical underpinnings of parliamentary sovereignty emphasizing the legal scope and boundaries of legislative power. The thesis argues that while parliamentary sovereignty traditionally implies unlimited legislative power, practical, legal, and theoretical considerations suggest that this power is not absolute." ~Dr Mele Tupou Vaitohi (Examiner) "This thesis discusses the question of whether a statute passed by parliament is, by definition, law, or whether parliament’s power is limited to the making of laws as defined according to some alternative standard. It then explores whether such “alternative standards” can be sourced in some concept of “the Constitution” (even in societies with “unwritten constitutions”) by way of interrogating “the constituent power” to make (and unmake) this concept." ~Dr Andrew Geddis (Examiner)
O uso de “moedas sociais” como instrumento de política social local
Authors: Ornellas Mauriel Ana Paula
Published: September 2024

O texto tem como objetivo problematizar as experiências recentes com “moeda social” a partir dos casos de municípios do Estado do Rio de Janeiro. Embora a origem das moedas sociais no Brasil seja do final dos anos 1990, no contexto recente de crise sanitária, houve um crescimento do interesse das prefeituras em criar moedas sociais para executar políticas de transferência monetária e inclusão produtiva. O texto é fruto de desdobramento de pesquisa em andamento e resulta de revisão bibliográfica e pesquisa documental. Depreende-se que, no contexto de crise do capital, agudizada pela crise sanitária, o uso da “moeda social” como política pública funciona para o aprofundamento da financeirização das políticas sociais, particularmente da Assistência Social, aliado a novas formas de gestão da força de trabalho, porém sob a legitimação do discurso de desenvolvimento local, “finanças solidárias”, empreendedorismo, autogestão e combate à pobreza.

Políticas para crianças e adolescentes e o pensamento de Amartya Sen: algumas problematizações necessárias
Authors: Silva Lima Rodrigo
Published: September 2024

O artigo resulta de revisão bibliográfica e análise documental e seu objetivo consiste em problematizar a adoção de diretrizes de organismos internacionais, por parte dos governos do Partido dos Trabalhadores, bem como a incidência do pensamento do economista Amartya Sen nas políticas sociais direcionadas a crianças e adolescentes no Brasil. Não se trata de uma análise rebuscada do conjunto de sua obra, mas da crítica às tendências liberais e a maneira como a sua proposição, em “Desenvolvimento como Liberdade”, tem sido incorporada, em especial, nas políticas para crianças e adolescentes. O texto está dividido em três partes, na primeira são tecidas considerações e críticas ao Desenvolvimento como Liberdade. Na segunda são evidenciadas as tendências das políticas sociais e os traços do pensamento de Amartya Sem nas políticas sociais. E na parte conclusiva, há um estranhamento à lógica liberal social e, sem eliminar os pontos considerados positivos do pensamento sobre desenvolvimento humano, compreende-se que, por mais avançadas que sejam as legislações, sem a crítica, a mobilização política e a lutas sociais, não teremos um horizonte de transformações societárias.

Tumor otak merupakan pertumbuhan sel abnormal di dalam otak, yang dapat bersifat jinak atau ganas. Kanker otak, yang merupakan bentuk ganas dari tumor otak, termasuk dalam jenis kanker yang paling agresif dan sering terdiagnosis pada berbagai rentang usia. Di Indonesia, terdapat sekitar 300 kasus tumor otak yang didiagnosis setiap tahunnya, termasuk pada anak-anak. Dalam menangani kasus tumor otak, diperlukan informasi mengenai lokasi spasial tumor dan tingkat keganasan tumor untuk merencanakan pembedahan dan pengobatan. Metode saat ini yang mengandalkan analisis manual pada citra Magnetic Resonance Imaging (MRI) dapat menyebabkan hasil yang bervariasi antar dokter (inter-observer error). Penelitian mengenai klasifikasi tingkat keganasan tumor otak pada citra MRI 3D juga masih terbatas. Oleh karena itu, dalam penelitian ini, akan dilakukan rancang bangun sistem yang menggunakan metode deep learning untuk segmentasi dan klasifikasi tingkat keganasan tumor otak pada citra MRI 3D. Dalam penelitian ini, telah berhasil dikembangkan sistem berbasis deep learning yang mampu melakukan segmentasi dan klasifikasi tingkat keganasan tumor otak pada citra MRI 3D. Model segmentasi tumor otak yang diusulkan menggunakan arsitektur U-Net dengan dice sebesar 82% dan mean IoU sebesar 94% pada 250 epoch. Sedangkan, model klasifikasi yang diusulkan menggunakan arsitektur Convolutional Neural Network (CNN) dengan base model ResNet50V2 yang sudah dilatih pada dataset ImageNet, head model yang terdiri dari satu lapisan dense dengan 512 nodes, dan lapisan output yang memprediksi input menjadi dua kelas, yaitu “LGG” dan “HGG” dengan accuracy sebesar 97% pada 10 epoch.
Integrating Machine Learning Utility in Tabular Data Synthesizer Training using Loss Function Learning

Machine learning (ML) utility has been the main evaluation metrics for data synthesizers. However, because ML utility cannot be simply calculated, none of the previous synthesizers were trained to reach the same level of ML utility as a training objective. This study aims to integrate ML utility into data synthesizer training using a transformer-based model as a learned loss function. The transformer was trained to estimate ML utility of synthetic datasets, then it’s integrated by backpropagating the difference between estimated and expected value. The integration has significantly improved the average ML utility of LCT-GAN and Realtabformer. The ML utility of LCT-GAN improved by 0.0158 for Contraceptive dataset, 0.031 for Insurance dataset, and 0.0561 for Treatment dataset. The ML utility of Realtabformer improved by 0.02 for Contraceptive dataset and 0.0024 for Insurance dataset. The increase affects the dataset distribution, correlation between features, and privacy, but the direction varies. Correlation coefficients indicate that synthetic data distribution gets closer to real data as ML utility improves. In addition to ML utility integration, this study has also shown that patterns between rows in a dataset can be learned, so better synthesizers can be developed based on them.

This paper compares the performance of a Sliding Mode Control (SMC) and Proportional-Integral (PI) controller under different voltage and load conditions. The study's findings underscore the need to account for load variations in system designs and to continuously seek system optimization irrespective of the controller type chosen. PI controller demonstrates effectiveness under certain circumstances. However, significant drops in voltage and current during abrupt load changes are obtained. On the other hand, SMC enables superior adaptability, efficiently managing voltage transients and load variations without any electrical disturbances, thereby maintaining system stability. A comparative analysis further emphasizes the SMC's superior time response and robustness against reference voltage changes. Consequently, SMC is proven to be a preferable choice over the PI controller in systems experiencing frequent voltage and load variations. However, both controllers achieve the potential for further response time optimization and stability.

Introduction: Oral health education is essential for adolescents, yet traditional methods face challenges in engaging this demographic. This study evaluates the effectiveness of a multimedia-based dental education program among high school students. This study was carried out to assess the impact of a comprehensive multimedia-based dental education program on oral health knowledge and practices among high school students.
Methods: A total of 228 students were recruited and randomly assigned to experimental (n=114) and control (n=114) groups. The experimental group received a four-week multimedia program, while the control group followed the standard curriculum. Outcome measures included oral health knowledge scores, brushing frequency, flossing habits, dietary choices, and observational assessments. Statistical analysis employed descriptive statistics, paired t-tests, and analysis of covariance (ANCOVA).
Results: The multimedia-based program led to a significant increase in oral health knowledge scores in the experimental group compared to the control group (Mean Change: 14.6, p < 0.001). Moreover, the experimental group demonstrated higher brushing frequency (p < 0.001), increased flossing habits (p < 0.001), and improved dietary choices (p < 0.05). Observational assessments showed higher adherence to oral hygiene practices in the experimental group (p < 0.001).
Conclusion: The multimedia-based dental education program effectively improved oral health knowledge and practices among high school students. This approach holds promise for scalable and engaging oral health education strategies.
