Authors: Straub Julia , Hurzlmeier Stefan , Hofmann Josef , Hehenberger-Risse Diana
Published: January 2022

Die Planung von Abwasserreinigungsanlagen stellt eine interdisziplinäre Leistung dar. Eine Beeinflussung der Projektkosten ist insbesondere zu Beginn des Projekts möglich. Gleichzeitig bestehen jedoch diverse Unsicherheiten, welche erst in Rahmen der Detailplanung im Projektverlauf beseitigt werden. In diesem Artikel wird am Beispiel einer Klärschlammvermeidungstechnologie eine Methode, wie durch die dynamische Kläranlagensimulation der Planungsprozess ab der Grundlagenermittlung unterstützt wird, demonstriert. Der Mehrwert liegt in der detaillierten und transparenten Darstellung der verfahrenstechnischen Zusammenhänge in der Abwasser- und Schlammbehandlung. Die Vorteile dieser Vorgehensweise werden an einem konkreten Beispiel dargestellt.

The objective: аnalysis of complications after endoprosthetic reconstruction in children and adolescents according to the Henderson classification of failure of limb salvage surgery modified by the International Society of Limb Salvage committee (ISOLS).

Materials and methods.This study evaluates complications rates and mode of failures after endoprosthetic reconstruction for the tumor around the knee in 97 patients treated from 2012 to 2018 in D. Rogachev National Medical Research Center of Pediatric Hematology, Oncology, Immunology.

Results. Overall  19,6 %  of  failures  were  identified.  The  most  common  postoperative  complications  were  structural failu res, infection and soft-tissue failure (6,19; 5,15 and 3,1 % respectively). None of the developed failures affected the timing of treatment protocol.

Conclusion. Literature  review  and  the  study  results  demonstrate  that  higher  risk  of  failure  in  the  paediatric  group of patients is attributed to deficiency of adjacent soft-tissue and bone, skeletal immaturity, using of expandable endoprostheses and increased patient activity at this age. Multicenter studies are needed to optimize prevention and management of failures after endoprosthetic reconstruction.

Introdaction.Ewing’s sarcoma of the pelvic bones in children and adolescents is a complex, poorly studied problem. This is explained by the rare occurrence of the tumor and its biological characteristics: aggressive course, a tendency to develop early hematogenous metastases and frequent relapses.

The objective: analysis of the results of treatment of 72 children and adolescents with localized and disseminated Ewing sarcoma with primary lesions of the pelvic bones was carried out.

Materials and methods.During the study, a retrospective and prospective analysis of the results of treatment of 72 children and adolescents with localized and disseminated Ewing sarcoma with primary lesions of the pelvic bones was carried out. The patients were divided into 3 clinical groups (Induction, High-dose chemotherapy, Polychemotherapy) depending on the treatment performed. The patients received treatment under the MMES-99 protocol.

Results.The overall 1-year survival rate of all 72 patients included in the study was 86,1 %, 3-year – 50,0 %, 5-year – 42,5 % and 10-year – 39,3 %; disease-free survival rate – 66,6; 43,9; 41,9 % and 38,3 % respectively. Our analysis of overall survival did not reveal statistically significant differences between the High-dose chemotherapy and Polychemotherapy groups (p= 0,83). There were also no statistically significant differences in relapse-free survival (p= 0,68).

Conclusion.Considering that the indicators of overall and relapse-free survival did not significantly differ when performing one or another type of consolidation (High-dose chemotherapy versus Polychemotherapy groups) in patients with a good antitumor effect achieved on induction, when choosing the type of consolidation, one should take into account the capabilities of the medical institution, the presence of experience and equipment for carrying out autologous transplantation, the desired total duration of therapy (with High-dose chemotherapy, it is significantly shorter), as well as the total cost of the program.

A statistical algorithm for fast estimation of heart rate and localization of cardiac sounds in phonocardiograms recorded by electronic stethoscopes
Authors:   Institute of hydrodynamics of NAS of Ukraine, Oliynik V. N.
Published: January 2022

A draft version of the algorithm for fast determination of duration of the systolic and diastolic phases of the cardiac cycle based on a statistical analysis of a digital phonocardiogram is presented. The developed technique includes localization of the cardiac tones in the record by a quantile dichotomy and modal analysis of the calculated time intervals between the adjacent detected peaks. Next, the scatter plot is constructed in terms of time intervals before and after each peak. The stability of the cardiac rhythm is determined by the density of the cluster occurring near the cross-section of two modal values plotted along the axes. At dominance of a cardiac component in the signal, the discussed approach allows quite reliable determination of the moments of the emergence of the first and second cardiac sounds tones practically on each of the cardiac cycles. This opens the possibility to analyze the variation in the duration of separate phases of heart contractions over time. Due to the work directly in the time domain and low computational costs, the algorithms of this class are suitable for application in portable diagnostic systems with limited processor power.
Mining Restaurant Data to Assess Contributions and Margins Data
Authors: Pallathadka Dr. Harikumar
Published: January 2022

The proposed business project seeks to ensure that at Monroe College’s Bronx Campus, the Jag Café emerges as a moderately priced restaurant offering convenience and promising breakfast and lunch experiences for students, faculty, and other individuals both in the campus community and in the neighborhood. Particularly, the proposed project involves the adoption and implementation of a new menu aimed at achieving family style services, food, and beverages. The proposal comes at a time when the cafeteria’s current menu is long and proves inconvenient in relation to the rate of order turnover. The location of the project is Kings Hall. Indeed, some of the anticipated and unexpected costs predicted to come with the new menu include the need to train employees and also ensure that several materials are in place to accommodate the new menu, and also ensure that the required raw materials and food preparation facilities are in place. However, the three-year sales project suggests that the financial benefits that might accrue from this project’s implementation are likely to outweigh the perceived costs. As such, the project is worth supporting because it not only promises profitability but also strives to make the Jag Café a place with quality meals at reasonable prices in the Bronx, as well as evolve as a home-style cafeteria in the campus.

Voting is arguably the most important as well as elementary right in democracy that has existed for the past hundreds of years; it has taken place in the context of a large- and small-scale community. The process transitioned from paper ballots to electronic voting machines (EVM) in the late 20th century, but even with all the advancement, transparency in the election process remained the same. Blockchain technology came in existence in 2008 with the introduction of Bitcoin by Satoshi Nakamoto, and in the last decade we saw enormous growth in development and execution of this technology in various fields e-voting is one of them, blockchain-based e-voting system has potential to improve the election process if utilized to its potential. Blockchain can eliminate the need to print ballot paper as it is secure, immutable and convenient to voters and can make elections more transparent.
Role of Photolithographic Process in Semiconductor Manufacturing
Authors: Pawar Avinash
Published: January 2022

Semiconductor Fabrication is a business of high capital speculation and quick evolving nature. To be serious, the creation in a fabrication should be viably arranged and planned beginning from the inclining up stage, with the goal that the business objectives, for example, on-time conveyance, high yield volume and viable utilization of capital concentrated hardware can be accomplished. Reproduction gives a successful tool to characterizing the way from serious ideas to true arrangements. More consideration is presently being centred on the precision of information gathered, implies for separating and bringing in information to the models, and staying up to date with changes in the fabrication. The directors and architects are these days properly worried about whether the model is a decent portrayal of the fabrication, and whether the outcomes are right. This is tended to through check and approval. The re-enactment group does approval by looking at the spreadsheet models and fabrication information, however formal systems have not been applied with the end goal of approval. The check and approval techniques are not officially recorded either. Additionally, the administration chose to explore different avenues regarding new programming called Lucent AP.
Eye Blink Artifact Removal from Cognitive EEG Data using ICA (Independent Component Analysis)
Authors: Motdhare Sagar S. , Mathur Dr. Garima
Published: January 2022

Eye blinking artifacts make electroencephalographic (EEG) elucidation as well as examination more difficult. In this paper, eye blinking artifacts are removed from cognitive EEG records by means of ICA. The blinks of eyes approximately at all times coincide with the event-related potentials (ERP) due to the experiment's design, generating ICA difficulties. To build a new data set, we combined spontaneous blink data with sole tryout ERP data. According to our findings, applying ICA to the combined data set results in a more logical separation, making EEG interpretation and analysis easier.
Modeling Authentication Mechanisms on Social Media Accounts
Authors: Deshpande Prof. Prachiti
Published: January 2022

Fake pages are used to exploit important categories, by using personal photos or personal information, in order to spread lies and discredit. This is illegal and threatens privacy. So, dealing with social networking sites has become a dangerous and risky thing. Hence, each important category seeks to have its pages on social networks distinctive and authenticated in order to attract real followers, in addition to removing all fake pages that use the name or pictures in order to mislead the followers. The authentication mechanisms on social media accounts differ from one site to another, but they are similar in terms of the objective, which is authenticating personal pages, in addition to showing a logo that distinguishes these pages from other pages. This mechanism requires everyone to follow specific procedures to complete authentication. Hence, obtaining a trust logo is not easy, accompanied by complicated procedures that are difficult to follow by normal users, unlike the important personalities who usually have managers who maintain their daily work and accounts.
Cued Zone Stimuli Simulation and Model Analysis
Authors: Rosemaro Ms. Elena
Published: January 2022

Attention may be a significant precursor to visual awareness but does not fulfil the sufficiency test. Moreover, the study uses a Posner endogenous spatial cueing paradigm to show that the time taken by the subject to discriminate the point of reference of a stimulus is minimized if the individual is signal towards the location of the stimulus. The reaction-time advantage is achieved without any reduction in discrimination accuracy. It implies that it cannot be said to have been caused by the speed-error trade off or distinctions in bias between the cued and uncued locations. Therefore, the subject was unaware of the stimuli to which processing was attenionally directed. In the end, the researchers conclude that attention is not a satisfactory condition for awareness.

Search Direction Generation via a Proposed Model
Authors: Omara Ibrahim
Published: January 2022

This study proposes a decomposition method through which they can be a successful solution to multi-stage stochastic nonlinear programs. The proposed method entails the scenario analysis method. The proposed method also performs its role via search direction generation in such a way that sets of quadratic programming sub-issues are solved in a parallel way, especially when the size is significant lower, compared to the case involving original problems at the respective iterations. Relative to the dual multiplier derivation, which focuses on non-anticipativity constraints, the proposed system advocates for the introduction of generalized reduced gradient approaches. This study’s focus is on the efforts seeking to establish a nonlinear programming model targeting problems with much nonlinearity, as well as linear constraints existing in large sparse sets; with the objective function on the focus. From experience, most of the linear programming issues are large (inordinately) because of their attempt towards approximation via piecewise linearization, translating into nonlinear issues. Also, most of the problems in the real-world have fewer variables linked to the objective function’s nonlinearity.
Moving Risk of Crowds in the Entrance Confluence Area in the Presence of Channelizing Facilities
Authors: Zhuang Yifan , Liu Zhigang , Huang Jiajun , Yang Lizhong , Schadschneider Andreas
Published: January 2022

In recent years, the measures to interfere the crowds movement with physical facilities (such as channelizing, separation railing) have become more and more common, but how they affect the crowd movement and what moving risks exist in the entrance confluence area have not been fully revealed. Therefore, this paper analyzes the moving risk of the crowds before the bottleneck entrance area, in the presence of the channelizing barriers by controllable laboratory experiments. The visual color cloud charts of the local density, speed and confusion degree of moving directions within the entrance confluence area are analyzed in the presence of different gaps (1.05m and 0.7m) channelizing barriers, to further quantify the motion risk of the crowds. The study finds that the narrower gaps of the channelizing railings, the larger area of high-risk zones, and they have clear ‘lane formation’ effect in shaping the risk zones. The both ends of the channelizing barriers are higher moving risk zones for multi-entry sides conditions, but the area before the middle channels also needs to be closely concerned when the participants entering from two opposite entering sides. The study will provide theoretical basis for evaluating the safety of the setting conditions of the channelizing barriers and conducting scientific crowd management decisions.

Published: January 2022

High-fidelity pedestrian tracking in real-life conditions has been an important tool in fundamental crowd dynamics research allowing to quantify statistics of relevant observables including walking velocities, mutual distances and body orientations. As this technology advances, it is becoming increasingly useful also in society. In fact, continued urbanization is overwhelming existing pedestrian infrastructures such as transportation hubs and stations, generating an urgent need for real-time highly-accurate usage data, aiming both at flow monitoring and dynamics understanding. To successfully employ pedestrian tracking techniques in research and technology, it is crucial to validate and benchmark them for accuracy. This is not only necessary to guarantee data quality, but also to identify systematic errors. Currently, there is no established policy in this context. In this contribution, we present and discuss a benchmark suite, towards an open standard in the community, for privacy-respectful pedestrian tracking techniques. The suite is technology-independent and it is applicable to academic and commercial pedestrian tracking systems, operating both in lab environments and real-life conditions. The benchmark suite consists of 5 tests addressing specific aspects of pedestrian tracking quality, including accurate line-based crowd flux estimation, local density estimation, individual position detection and trajectory accuracy. The output of the tests are quality factors expressed as single numbers. We provide the benchmark results for two tracking systems, both operating in real-life, one commercial, and the other based on overhead depth-maps developed at TU Eindhoven, within the Crowdflow topical group. We discuss the results on the basis of the quality factors and report on the typical sensor and algorithmic performance. This enables us to highlight the current state-of-the-art, its limitations and provide installation recommendations, with specific attention to multi-sensor setups and data stitching.

Published: January 2022

AIM. Analyze the problems and prospects of the development of modern pathopsychology in the era of a new revision of the classifications of mental disorders, overcoming the categorical approach and achieving progress in the treatment and psychotherapy of psychotic disorders. The most important role of psychological theory and psychological experiment based on it in determining the patterns of mental activity disorders is comprehended, the problem of typicity and specificity of individual symptoms of mental disorders to a particular mental disorder, the role of psychological mechanisms and conditions for the occurrence of psychopathological symptoms is considered. In the conditions of modern progress in medicine and psychotherapy, pathopsychology needs an incentive to actively rethink the rich experimental experience and further development. An obstacle on this path is the historical narrowing of the professional framework of the pathopsychologist to the level of nosological service (Bratus B.S.), overdiagnosis of individual nosological headings to the detriment of others.
CONCLUSIONS. In the context of the progress made in the treatment and psychotherapy of mental disorders, and against the background of current changes in the classifications of mental disorders, the problems and trajectories of the development of modern pathopsychology are identified. The importance of methodological renovation in understanding the basic provisions and problematic niches of pathopsychology, rethinking experimental experience and implementing modern experiments in compliance with the rules of scientific research, correlation with modern scientific knowledge, as well as the importance of reflection on the professional tasks of a pathopsychologist is shown. The inclusion of psychological intervention in the active arsenal of tasks of a pathopsychologist can transform his professional activity.
Detecting Elevated Pore Pressure due to Wastewater Injection Using Ambient Noise Monitoring
Authors: Yang Zhuo , Yuan Congcong , Denolle Marine A.
Published: January 2022

The injection of large volumes of wastewater has induced earthquakes from June 2010 to July 2011 along the Guy–Greenbrier fault in Arkansas. We measure time-dependent changes in seismic velocities underneath three temporary seismic stations, using the daily autocorrelations of ambient seismic noise. We do not find any effect of the pumping rate or volume injected in the changes in velocity. However, the induced earthquakes’ ground motions are associated with an extreme reduction in seismic velocities. The magnitude of the changes surpasses ten times the values typically found in other earthquake settings. Our full-waveform investigation suggests that the changes mainly occurred around the top of the Ozark aquifer. We interpret these extreme changes as a result of dynamic shaking in the elevated pore pressure system of the Ozark aquifer.

Increasing Capacity for Evaluation of Community-Based Organizations: Lessons from the Ohio Equity Institute
Authors: Walker Daniel M. , DePuccio Matthew J. , Hefner Jennifer L. , Sieck Cynthia , Hogan Tory H. , McAlearney Ann Scheck , Swoboda Christine , Huerta Timothy R.
Published: January 2022

Background: Community-based organizations (CBOs) play an important role delivering disease prevention and health promotion activities to address community health needs and improve the health of individuals living in their communities. While CBOs play this important role, evaluation of the services they deliver is hampered by limited infrastructure to systematically collect data from these organizations. To address this gap, we report on a case study of the development of the Ohio Equity Institute (OEI) Data Portal. The OEI is a statewide initiative that supports 65 CBOs across Ohio to deliver 3 evidence-based interventions (ie, CenteringPregnancy, Community Health Workers, and Home Visiting) to address infant mortality in underserved populations. Methods: Employing principles of community-engaged stakeholder research and user-centered design, we conducted Plan-Do-Study-Act cycles, including semistructured interviews with 43 key informants, to improve the development, implementation, and use of the OEI Data Portal. Results: This process identified both technical and implementation challenges, and offered opportunities to make improvements to the data collection system itself as well as to the integration of this system with CBO workflows. These improvements yielded significant gains in terms of the quantity and quality of data submission, ultimately contributing to ongoing outcome evaluation efforts. Conclusion: Our findings provide important insight into the challenges experienced by CBOs when participating in a statewide CBO data evaluation infrastructure development and implementation. As Ohio and other states push to expand collaborations between CBOs and health care organizations, leaders should leverage existing data collection to facilitate a more comprehensive and effective process.

The Impact of Academic Stress and Spiritual Intelligence on Subjective Well-Being in Students During the Pandemic Period
Authors: Aliyah Syahidah Farah , Andrini Farida Ika
Published: January 2022

The COVID-19 pandemic has led to a shift in the learning system from offline to online. Online learning in the long term can affect the subjective well-being of students. Several previous studies have linked students’ subjective well-being with academic stress or spiritual intelligence. Thus far, studies have not examined whether academic stress and spiritual intelligence can simultaneously contribute to students’ subjective well-being. This research intended to determine the contribution of academic stress and spiritual intelligence to students’ subjective well-being. 116 students in one municipality in East Java province completed three measuring instruments, specifically the subjective well-being scale, academic stress scale, and spiritual intelligence scale. Data were tested using multiple linear regression. The findings illustrated that academic stress partially affected subjective well-being (t = 8.567; p <0.05), spiritual intelligence partially affected subjective well-being (t = 3.677; p <0.05), and academic stress and spiritual intelligence in combination affected subjective well-being (F = 44.567; p < 0.05; R2 = 0.386). These results suggested that 38.6% of the variation in subjective well-being in students could be explained by academic stress and spiritual intelligence. Therefore, in order to maintain their subjective well-being during this long pandemic, students are advised to improve their capacity to deal with academic stress and develop their spiritual intelligence.

Published: January 2022

Marriage is a task of individual development. Conflicts, problems, and mismatches of expectations must be faced in marriage. Couples who are unable to resolve these issues will be more likely to choose separation or divorce. There are high divorce rates in Indonesia. Pre-marital guidance is part of efforts to prepare prospective married couples to achieve the expected quality of marriage. Currently, pre-marital guidance is carried out conventionally, such as through seminars or training. Meanwhile, what is needed by today’s Millennial society is clear, accurate, and flexible information to be accessed anywhere and anytime. For this reason, efforts are needed to develop a cyber education-based pre-marital guidance service model. The purpose of this study was to provide an analysis of material needs for the Cyber Education-Based Pre-Marriage Guidance Model. Descriptive quantitative methodology was used and data were collected through a Google Forms questionnaire. This questionnaire consisted of 18 questions compiled with the aim of uncovering needs relating to the following: 1) formulation of problems; 2) determination of the type of information or data; 3) data collection procedures; 4) data processing; and 5) decision-making based on data analysis results. 280 students from LPTK universities throughout Java participated, including from Universitas Negeri Malang, Universitas Negeri Surabaya, Universitas Negeri Semarang, Universitas Negeri Yogyakarta, and Universitas Pendidikan Indonesia.

The Effect of the Appreciative Inquiry Method on Improving a Sense of Community Among 2021 IFoP Members
Authors: Rohmatussyifa Zahroh , Weni Utami Sri
Published: January 2022

A sense of community is very important for the management of an organization. It can help maintain the continuity of the organization and the proactive attitude of its members. Based on the results of a pretest conducted on 21 IFoP administrators for the 2021 period, it was found that four administrators had a very low sense of community and three administrators had a low sense of community. These seven administrators received an intervention in the form of an appreciative inquiry method to increase their sense of community. The research design used in this method was a quasi experiment with one-group pretest-posttest design. The pretest and posttest used a modified measuring instrument called Sense of Community Index-2 from McMillan & Chavis. Meanwhile, the appreciative inquiry method used the stages proposed by Cooperrider, Whitney and Stavros. The results showed that there was a difference in the level of sense of community after the intervention compared to before. The Wilcoxon test that was carried out on the pretest and posttest scores of the research subjects showed a significant result with a p-value of 0.018 (< 0.05). Based on these results, it can be concluded that the appreciative inquiry method can be used to increase the sense of community.

The EU’s strategic projection in the Indo-Pacific
Authors: López-Aranguren Juan Luis
Published: January 2022

The Indo-Pacific is becoming the new geopolitical axis of the planet for multiple reasons, among which three stand out: security (with six nuclear powers in the area, some of them amidst clearly growing tensions), demography (with 64 percent of the world population) and economy (with 62 percent of world GDP). Since its founding, the European Union has been absent in the development of a strategy for the region, an absence that has recently ended with the publication of national strategies of three member states (France, Germany, and the Netherlands), as well such as the EU announcement of a future EU strategy for the region. This paradigm shift may mark the beginning not only of greater European cohesion in terms of strategic projection, but also of greater European geopolitical assertiveness in a post-COVID-19 world in the Indo-Pacific and other regions. This article will trace the birth and evolution of the Indo-Pacific concept, will identify the reasons for its geostrategic importance for the European Union, and will analyze both the three national strategies of France, Germany, and the Netherlands as well as the announced EU strategy for the region.

La enfermedad de Parkinson (EP) es una enfermedad principalmente conocida por sus síntomas motores. Sin embargo, esta enfermedad puede cursar con el deterioro de ciertas funciones cognitivas (memoria, atención, habilidades visuoespaciales…), asociándose a una reducción de la calidad de vida de las personas con EP y de su entorno más cercano. A medida que la enfermedad avanza, incrementa la necesidad de cuidado, que suele estar proporcionado por cuidadores informales. El presente briefing está destinado a entidades o profesionales que tengan interés en aplicar en sus centros una intervención combinada de rehabilitación cognitiva en personas con EP y psicoeducación en sus familiares cuidadores. El objetivo es mejorar las funciones cognitivas y la calidad de vida de las personas con EP y sus familiares. La implicación de los familiares puede proporcionar un enfoque integral en el proceso rehabilitador y potenciar los beneficios en las personas con EP, así como ofrecer estrategias para fomentar una mejor calidad de vida en los propios cuidadores.
Housing conditions in social housing stock vs. marginalisation risk – evidence from Poland
Authors: Rataj Zuzanna , Suszynska Katarzyna
Published: January 2022

Low-income households in the Polish public housing stock sometimes encounter the risk of housing exclusion, yet this experience is relatively more frequent among the tenants of council flats. The aim of this paper is to present the results of research on housing standards in the public housing stock in Poland. Pursuant to Polish law, social housing is part of public housing assistance (Przymeński 2016), addressed to very-low- and low-income households which are not capable of satisfying their housing needs on their own. The paper uses desk research, statistical data analysis and questionnaire interviews with dwellers of council flats in Poland. Furthermore, the achievements of international housing policy are taken into account. The results show that the standard in the public stock, especially in council flats, in Poland is poor and hinders low-income households in addressing their hous- ing needs. Small areas of dwellings, overcrowding, low quality of building materials are all identified as significant determinants increasing the risk of housing exclusion in council flats.

Актуальность. Математическое моделирование геологических систем является актуальным как теоретически, так и практически. Обратные прикладные задачи позволяют систематизировать знания об исследуемых моделях. В настоящей статье рассматриваются задачи об оценке глубины заложения заряда взрывчатого вещества в просадочных грунтах с целью их уплотнения и, как следствие, снижения просадочности. Такой метод уплотнения широко применяется при проведении работ на объектах гражданского строительства, изменении рельефных особенностей местности и т.д. Следует отметить, что на территории России порядка 17 % поверхности земной коры представлены просадочными лёссами. Цель: аналитическое и численное моделирование решения обратных задач в геологических системах при уплотнении лёссов глубинными взрывами. Методы: итерационные методы решения задач, методы компьютерного моделирования в рамках исследования геологических систем, статистика выводов. Результаты. Предлагаются аналитические и численные решения рассматриваемой обратной прикладной задачи геологической системы. Описаны решения при условиях полного поглощения газа, образованного в результате взрыва сосредоточенного заряда, окружающим его просадочным грунтом (происходит уплотнение лёсса) и полного отражения газа от грунта (происходит выброс на поверхность). Подробно математически изучены различные состояния просадочного лёсса с характерными свойствами изотропности и анизотропности геологической системы. Проведён вычислительный эксперимент поиска приближённого итерационного решения обратной задачи для определения глубины проведения взрывов с целью уплотнения лёссов. Вычисления проводились с учётом имеющихся экспериментальных данных на примере объекта гражданского строительства Северного Кавказа. Выводы. Проведённые исследования указывают на адекватность предлагаемого подхода оценки глубины заложения заряда. Численное решение задачи найдено с высокой точностью и с минимальными вычислительными затратами.

Актуальность. Смачиваемость нефтенасыщенных коллекторов в значительной степени влияет на технологические особенности разработки эксплуатационных объектов, прежде всего, на эффективность заводнения нефтяных пластов. Возможности определения смачиваемости по данным геофизических исследований скважин позволяют учитывать данный показатель при геолого-технологическом моделировании разработки эксплуатационных объектов, в том числе при оптимизации заводнения нефтяных пластов. Данная задача решена для условий залежей терригенных нефтенасыщенных коллекторов на основе комплексирования методов определения пористости, бокового электрического каротажа и микробокового каротажа. В публикации представлены результаты и анализ динамики приемистости нагнетательных скважин для битуминозных, гидрофобизированных и гидрофильных коллекторов. Для участков с низкой приемистостью скважин предложены геолого-технические мероприятия по оптимизации системы заводнения нефтяных пластов. Цель: оценить возможность достоверного определения смачиваемости нефтенасыщенных терригенных коллекторов, провести сравнительный анализ влияния показателя смачиваемости коллекторов на эффективность заводнения нефтяных пластов, для различных геологических условий предложить эффективные технологические условия разработки эксплуатационных объектов.

Актуальность исследования обусловлена возрастающей потребностью применения карьерных самосвалов с дизель-электрическим (гибридным) приводом для разработки полезных ископаемых. Улучшение рабочих и стоимостных характеристик электропривода карьерных самосвалов способствует уменьшению затрат при разработке полезных ископаемых. Цель: поиск эффективного подхода для оптимизации одноименнополюсного синхронного двигателя для привода колес карьерного самосвала, позволяющего решить проблему высокой потребности в вычислительных ресурсах при расчете трехмерной модели магнитного поля двигателя; выработка рекомендаций к проектированию одноименнополюсного синхронного двигателя с обмоткой возбуждения на статоре; оптимизация с целью уменьшения потерь мощности и максимального тока двигателя при заданной тяговой характеристике привода для снижения номинального тока и стоимости инверторного полупроводникового модуля электропривода карьерного самосвала с рассматриваемым типом двигателя. Объекты: конструкция шестиполюсного девятифазного одноименнополюсного синхронного двигателя с обмоткой возбуждения на статоре мощностью 370 кВт. Методы: безградиентный метод оптимизации, математическое моделирование, двухмерный метод конечных элементов, метод схем замещения. Результаты. Предложен новый, эффективный с точки зрения точности расчета характеристик и вычислительных затрат, подход к оптимизации одноименнополюсного синхронного двигателя. В результате проведенной оптимизации потери в двигателе и максимальный ток, потребляемый двигателем от инвертора, были значительно снижены. Достигнутое снижение максимального тока позволяет снизить стоимость полупроводниковых модулей инвертора в 1,4 раза, а также позволяет снизить на ту же величину переменную составляющую тока звена постоянного тока инвертора.

Актуальность темы обусловлена возможностью использования такого вида топлива, как парогазовые продукты пиролиза древесных отходов, в качестве основного или вспомогательного топлива для выработки электрической энергии. Направления, связанные со снижением углеродных выбросов, позволят расширить области применения пиролиза как средства переработки промышленных отходов, сводя к минимуму их воздействие на окружающую среду. Цель: исследование вопросов повышения эффективности выработки электрической энергии на двигателях внутреннего сгорания и газотурбинных установках при работе на продуктах пиролиза древесных отходов с целью сокращения потребления не возобновляемых энергоресурсов, таких как уголь, нефть и природный газ. Объекты: установка пиролиза древесных отходов, двигатели внутреннего сгорания и газотурбинные установки, работающие на парогазовых продуктах пиролиза древесных отходов. Методы: численные методы исследования на основе математического моделирования систем и элементов двигателей внутреннего сгорания и газотурбинных установок на основе материальных и энергетических балансов. Результаты. Разработана математическая модель и программа для теплового расчета двигателей внутреннего сгорания и газотурбинных установок, сжигающих парогазовые продукты пиролиза. Проведен параметрический анализ влияния температуры выхода парогазовых продуктов из пиролизной установки на эффективность работы, электрическую мощность и температуру уходящих газов рассмотренных силовых агрегатов. Установлено, что для утилизации парогазовых продуктов пиролиза с целью получения электрической энергии наиболее эффективно применение двигателя внутреннего сгорания, работающего по термодинамическому циклу Тринклера, и газотурбинной установки, работающей по термодинамическому циклу Брайтона, при этом абсолютный электрический коэффициент полезного действия в номинальном режиме работы пиролизной установки составляет 23,34 и 22,28 % соответственно. Выявлено, что при использовании парогазовых продуктов пиролиза в качестве вспомогательного топлива к метану в объемной составляющей 25 %, снижение мощности силового агрегата ожидается не более 10 %.
