Бинарный предикат, транзитивное замыкание, две-три переменные: сыграем в домино?
Authors: Рыбаков Михаил Николаевич
Published: May 2023

Проблемы укладки домино являются удобным инструментом оценки алгоритмической сложности задач, возникающих в различных разделах математики, в том числе в логике. В работе описывается моделирование проблем домино с помощью средств языка логики предикатов, а также с помощью некоторых дополнительных средств, в том числе не выразимых элементарно. Это дает возможность получить как простые доказательства уже известных фактов о неразрешимости проблемы выполнимости формул различных фрагментов логики предикатов, так и некоторые новые результаты. Так, известно, что проблема выполнимости формул логики предикатов, содержащих не более двух предметных переменных, алгоритмически разрешима; известно также, что свойство транзитивности бинарного отношения и операция композиции двух бинарных отношений могут быть выражены в языке первого порядка с использованием трех переменных. В работе показано, что если добавить к языку первого порядка оператор проверки транзитивности бинарного отношения (или более сильное средство – оператор транзитивного замыкания) и оператор композиции, то получим язык с сильно неразрешимой проблемой выполнимости формул от двух переменных, построенных в сигнатуре с одной бинарной предикатной буквой и равенством.
A Topological-algebraic Approach to the Compactness Theorem of Classical Logic
Authors: Shi Weijun
Published: May 2023

There are some methods of proof of the compactness theorem for classical logic which bypass the completeness theorem. Among them are the purely topological one, the purely algebraic one, and the hybrid one. These methods make essential use of either Tychonoff's Theorem, the concept of ultraproducts or the concept of Cantor sets as topological spaces. Instead of these conceptual tools, the paper provides the theorem with a method of proof that appeals to the concept of Stone spaces of Boolean algebras. In connection with a classical logical system (a propositional calculus or a predicate calculus), the method consists of five components. Firstly, the problem of the compactness of the logical system is reduced to that of the compactness of some topological space. Secondly, what is called the Lindenbaum algebra of the system is set up, which is in fact a Boolean algebra. Thirdly, it has to be shown that the Stone space of the Boolean algebra is compact. Fourthly, the set of sentences whose equivalent classes are members of the Stone space is shown to be satisfiable or simultaneously true. Finally, a homeomorphism is constructed between the topological space and the compact Stone space. Additionally, the method admits of a natural generalisation to the proof of the compactness theorem for modal logic.
Терминология и толкование в «Логике» Макария Петровича
Authors: Алексеева Алина Сергеевна
Published: May 2023

В статье рассматривается один из приемов оформления толкований в «Логике» Макария Пе́тровича – глоссирование заимствованного понятия разного происхождения при помощи союза или. На примере четырех сочетаний (копула vs. связка, термин vs. связка, метод vs. (философское) расположение, аналисис vs. разбирание понятий vs. произведение или формование идей) показано, что вторым компонентом пары является лексема со славянским корнем, которая освоена русским языком. Подобная модель лишь в редких случаях соотносится с латиноязычными источниками приведенных сочетаний: Institutionesphilosophiae rationalis methodo Wolfii conscripta (1735 г.) и Elementa philosophiae recentiorisusibus juventutis scholasticae accommodata (1747 г.) Ф.Х. Баумайстера – в большинстве случаев добавления Петровича являются продуктом его оригинального творчества.
При построении объяснений о. Макарий использует как лексику русского языка, так и полонизмы, причем словообразовательные модели польского языка (например, прилагательные на -ичный: криптичнный, аналитичный, гипотетичный) характерны для всего текста «Логики».  Сопоставление лексем с историческими словарями русского языка и текстами XVIII в. и ранее из Национального корпуса русского языка показало, что некоторые слова (копула, еротематический, формование, формовать, диспутовать, криптичнный, аналитичный, гипотетичный) или их варианты (мефод и аналисис по Рейхлиновой системе чтения) впервые употребляются именно в «Логике» Макария Петровича.
Логическая операция деления у Иоанна Дамаскина и Никифора Влеммида
Authors: Тоноян Лариса Грачиковна
Published: May 2023

В статье исследуется влияние логики Аристотеля, в частности, методов определения и деления на византийскую мысль. Для анализа мы выбрали два наиболее популярных в Византии пособия по логике, принадлежащих Иоанну Дамаскину и Никифору Влеммиду.  Св. Иоанн Дамаскин (ок. 675 – ок. 750) в своем «Источнике знания» постоянно и активно пользуется логическими методами, в особенности, дихотомическим делением, подробно разбирая то, что позже было названо Древом Порфирия.  В нарушение принципа дихотомического деления при делении одушевленной [сущности] у него получаются три понятия: животные, зоофиты и растения. В статье показано, что эти и другие особенности в его изложении операции деления восходят к поздним неоплатоникам, которых он, правда, не называет. Труд Дамаскина был вскоре переведен на латинский язык, а позднее неоднократно переводился на славянский и русский языки, способствуя знакомству с логикой Аристотеля и возникновению на Руси логической терминологии. В отличие от труда Дамаскина сочинение известного в Византии ученого Никифора Влеммида (1197–1272) до сих пор не переведено с греческого ни на один из современных языков и остается малоисследованным. В данной статье мы анализируем две главы его «Логики», посвященные логической операции деления и анализу древа Порфирия.  Выявлены некоторые отличия в привычном изложении древа Порфирия также и в компендиуме Никифора Влеммида. В частности, Влеммид не отходит от принципа дихотомического деления: он объединяет зоофиты и растения в один разряд непередвигающихся и убирает деление разумных существ на смертных и бессмертных.
Некоторые предварительные условия для создания «многомировой теории всего» и развития интеллектуальной интуиции
Authors: Карпенко Иван Александрович
Published: May 2023

В статье подвергаются сомнению некоторые классические принципы мышления, основанные на традиционной интеллектуальной интуиции. В частности, оспаривается интуитивная приемлемость требования непротиворечивости, принципа «из противоречия следует всё, что угодно», закона исключённого третьего и некоторых других. В литературе, особенно логической, этой проблематике посвящено множество исследований в течение XX-XXI веков. В настоящей работе формулируется новый подход, основанный на гипотезе «многомировой теории всего» – гипотезе, которая базируется на идее признания мультивселенной, как актуальной реальности. Такая гипотеза бросает вызов существующим подходам к научному исследованию, понятию и критериям научной теории. Она требует отказа от ряда традиционных представлений, как контринтуитивных, например, от роли классического эксперимента в обосновании теории. Работа исходит из допущения, что мультивселенная является объективной реальностью. Для обоснования основной идеи не важно, какая именно из распространённых в настоящее время многомировых моделей близка к действительности, значение имеет только что, что такая модель должна быть следствием актуальных исследований в современной физике и космологии (например многомировая интерпретация квантовой механики, струнный ландшафт, хаотическая инфляция и некоторые другие).Высказывается предположение, что интеллектуальная интуиция, соответствующая корректному описанию мира, должна основываться на многомировом подходе, поскольку именно такой подход позволяет снять некоторые нерешённые проблемы, как контринтуитивные. Обосновывается, что соответствующим логическим базисом для такой теории может стать паранепротиворечивая и квантовая логики, как строящиеся на интуитивных представлениях, приближенных к действительному состоянию мира (фундаментальному устройству мира).

Authors: OKTAY Gülseren , KUYUCU Yunus Emre
Published: May 2023

Giriş: Tüm dünya yaklaşık üç yıldır COVID-19 pandemisinin etkisi altındadır. Sağlık sistemleri de bu süreçten olumsuz etkilenmiştir. Çalışmamızda da üçüncü basamak aile hekimliği poliklinik başvurularının pandemi döneminden nasıl etkilendiğini inceleyerek literatüre katkı sağlanması amaçlanmıştır. Yöntem: Gaziosmanpaşa Üniversitesi Tıp Fakültesi Hastanesi aile hekimliği polikliniğine 15.03.2020 -31.05.2020 tarihleri arasında yapılan başvurular pandemi dönemi olarak değerlendirildi. Bir yıl önceki aynı tarihlerde yapılan başvurularla karşılaştırıldı. Hastalar demografik bilgilerine, başvuru nedenlerine, tanılarına ve başvuru sıklıklarına göre retrospektif olarak incelenmiştir. Bulgular: Aile hekimliği polikliniğimize pandemi döneminde 276 başvuru ve pandemi öncesi dönemde ise 899 başvuru yapılmıştır. Pandemi döneminde pandemi öncesi döneme göre başvuran kişilerin yaş ortalamasını arttığı saptandı. Pandemi döneminde yapılan başvuruların %26,8’ini 65 yaş ve üstü ve % 54’ünü de erkekler oluşturmaktadır. Ayrıca en sık başvuru sebebi de %43,2 oranında reçete yazdırmaydı. Sonuç: Pandemi döneminde poliklinik başvuruların yaklaşık yüzde yetmiş oranında azalması sevindiricidir. Ancak özellikle risk altındaki kişilerin başvurularının ağırlıkta olması ve en sık başvuru sebebinin reçete yazdırma olması ek tedbirlere ihtiyaç olduğunu göstermektedir.
Method and Algorithm of Autonomous Flight Trajectory Planning of an Unmanned Aerial Vehicle When Monitoring the Fire Situation in Order to Detect the Source of Ignition Early
Authors: Tomakova R. A. , Filist S. A. , Brezhneva A. N. , Gorbachev I. N. , Zaikin Ya. O.
Published: May 2023

The purpose of the research is to develop a method and algorithm for autonomous planning of the flight path of an unmanned aerial vehicle when monitoring the fire situation, which are designed for early detection of the source of ignition. Since timely detection of a fire source at the stage of its development allows to reduce both material and human losses, the development of a method and algorithm for autonomous flight trajectory planning of an unmanned aerial vehicle when monitoring the fire situation in order to detect the source of ignition early is an urgent, important task.

Methods. A method for detecting the source of ignition is proposed. The method is based on three flight plans. Plan A provides for a flyby of the monitored area by gas with determination of the concentration of a harmful substance in each pixel of the monitoring area. When a pixel is detected in which the concentration of a harmful substance exceeds the threshold level, the flight control of the UAV is carried out through plan B, which provides for local planning to achieve the pixel target, which is determined by calculating local differential operators in a nine–element mask. Plan B allows the UAV to fly directly to the source of the fire and determine its coordinates. Flight plan C provides for the return of the UAV to the point of departure from any pixel of the monitoring zone.

Results. An algorithm for controlling the UAV flight path has been developed, which allows determining local target pixels and building a local flight plan on this basis. The basis for constructing a local flight plan is the rule "at least three pixels on the tack", which allows you to obtain a nine-element matrix with known concentrations of harmful substances in the target pixel and determine those pixels of the local flight plan in which it is not possible to obtain this matrix.

Conclusion. Mathematical modeling of the UAV flight control algorithm according to the proposed test method was implemented in the Matlab 8.0 package and showed control stability and high speed of reaching the coordinates of the pixel of the ignition source, exceeding the speed of achieving the set goal by 1.5...2 times, depending on the location of the ignition source relative to the direction of the flyby of the monitored territory.
Compensation for the Error of Narrowing the Defuzzification Range by the Areas’ Ratio Method
Authors: Milostnaya N. A.
Published: May 2023

The purpose of research is to examine the hypothesis that the area ratio method can be used to compensate for the defuzzification interval narrowing error inherent in traditional models, such as center of gravity sums, height models, first maxima, mean maxima, and last maxima.

Methods. A fuzzy model consisting of two input variables and one output variable was used to analyze the properties of the area ratio method. The input variables had two triangular membership functions each, and the output variable had three triangular membership functions. The knowledge base consisted of four fuzzy rules. Zadeh's compositional rule was used as an implication model. Two models of classical center of gravity and a model based on the area ratio method were used in the defuzzification process.

Results. In the course of experimental studies, it was found that the proposed defuzzifier based on the area ratio method compensates the error of narrowing the defuzzification interval. It was also found during the experimental studies that when using the center-of-gravity model, a resultant surface that only 50% overlaps with the caliper of the output variable is formed at the output, which forms the error of defuzzification interval narrowing. When the area ratio method is used, the resulting surface overlaps 100% with the output variable caliper, suggesting that the area ratio method eliminates the error associated with defuzzification interval narrowing.

Conclusion. This article presents a fuzzy MISO model that is used to analyze the properties of the area ratio method. A distinctive feature of the proposed model is the use of the area ratio method in defuzzification. Analysis of its simulation process has shown that this method allows to compensate the error of defuzzification interval narrowing.

Published: May 2023

The purpose of research– development of bioimpedance spectroscopy methods to develop on their basis objective and realistically accessible criteria for assessing the severity and prognosis of diseases, as well as evaluating the effectiveness of treatment methods, developing criteria for the use of conservative therapy options and surgical interventions in severe patients.

Methods. The proposed method involves the use of a recurrent modified Voigt model as a biomaterial segment impedance model. For each model of a biomaterial segment, a Cole plot is plotted in a given frequency range. At the stage of determining the parameters of each of the models, a recurrent procedure is performed, which is the solution of systems of nonlinear equations, starting from one link of the Voight model with a subsequent increase in their number at each iteration step, until the value of the approximation error by the Voight model of the Cole experimental plot reaches allowed value.

Results. As a result of the study, fundamentally new results have been obtained that allow creating intelligent decision support systems for diagnosing socially significant diseases. A bioimpedance analysis model based on multifrequency bioimpedance measurement has been created, which makes it possible to decompose the biomaterial impedance into structural elements, on the basis of which to determine descriptors for neural network classifiers of medical risk. In the work, an analysis of classifier errors was carried out in classifying the risk of acute destructive pancreatitis, which showed that the maximum value of the quality indicators of various classifier models was 78%, the minimum was 62%, demonstrating close values to the quality indicators of the ultrasound diagnostic method.

Conclusion. The use of multifrequency sensing and modified Voight models in neural network classifiers of medical risk makes it possible to build clinical decision support systems for diagnosing socially significant diseases, as well as the ability to improve classification quality indicators and expand the functionality of intelligent medical decision-making systems.

Published: May 2023

Background

The management of chronic pelvic pain in women with endometriosis is complex and includes the long-term use of opioids. Patients not fully responsive to drugs or ineligible for surgical treatments need efficient alternatives to improve their quality of life and avoid long-term sequelae.

Objective

This randomized controlled trial aimed to assess the effects of repeated at-home administrations of a 20-minute virtual reality (VR) solution (Endocare) compared with a sham condition on pain in women experiencing pelvic pain due to endometriosis.

Methods

Patients were instructed to use the VR headsets twice daily for at least 2 days and for up to 5 days starting on their first day of painful periods. Pain perception was measured using a numerical scale (0-10) before and 60, 120, and 180 minutes after each treatment administration. General pain, stress, fatigue, medication intake, and quality of life were reported daily by patients.

Results

A total of 102 patients with endometriosis were included in the final analysis (Endocare group: n=51, 50%; sham group: n=51, 50%). The mean age was 32.88 years (SD 6.96) and the mean pain intensity before treatment was 6.53 (SD 1.74) and 6.22 (SD 1.69) for the Endocare group and the sham control group, respectively (P=.48). Pain intensity decreased in both groups from day 1 to day 5 along with a decrease in medication use. Maximum pain intensity reduction of 51.58% (SD 35.33) occurred at day 2, 120 minutes after treatment for the Endocare group and of 27.37% (SD 27.23) at day 3, 180 minutes after treatment for the control group. Endocare was significantly superior to the sham on day 1 (120 minutes, P=.04; 180 minutes, P=.001), day 2 (0 minutes, P=.02; 60, 120, and 180 minutes, all P<.001), and day 3 (60 minutes, P=.01; 120 minutes, P=.005; 180 minutes, P=.001). Similarly, the mean perceived pain relief was significantly higher with Endocare on day 1 (120 and 180 minutes P=.004 and P=.001, respectively) and day 2 (60, 120, and 180 minutes P=.003, P=.004, and P=.007, respectively) compared to the control. No adverse event was reported.

Conclusions

This study confirmed the effectiveness and safety of self-repeated administrations of a VR immersive treatment used at home while reducing overall pain medication intake in women diagnosed with endometriosis experiencing moderate-to-severe pelvic pain.

Authors: Kim Sooyeon , Lee Jungsue , Rim Chai Hong
Published: May 2023

BACKGROUND

Although recent studies have shown favorable results after local treatment for oligometastases, the clinical decision of applying local treatment for oligometastatic hepatocellular carcinoma (HCC) remains controversial.

OBJECTIVE

This meta-analysis aimed to investigate the benefits of local treatment for HCC oligometastases

METHODS

Pubmed, Embase, Medline, and Cochrane library were searched for studies until May 1st, 2022. Clinical studies involving at least five cases of HCC oligometsatases treated with local modalities were included. The primary endpoint was overall survival (OS). The benefit of local treatment was assessed as the pooled odds ratio (OR) among comparative series, and the pooled OS percentile was calculated from all studies including patients treated with local treatment. Complications of grade ≥3 were assessed subjectively.

RESULTS

A total of 10 studies involving 527 patients were included. Radiotherapy and radiofrequency ablation (RFA) were mainly performed (six and five studies) as local modalities treating oligometastases. Pooled OR of comparative series favored the use of local treatment (4.664, 95% confidence interval [CI]: 2.5958.380, p <0.001, I2: ~0.0%). Including all cohorts with patients underwent local treatment, pooled rates of 1-year OS was 71.8% (95% CI: 59.0-81.9; I2=81.5%), and pooled 2-year OS was 43.3% (95% CI: 29.1-59.6; I2=85.4%). Except for temporal or pre-existing toxicities, grade ≤3 complications were reported less than 10% in most studies, although common toxicities include pneumothorax and hematologic deficiency after RFA and radiotherapy, respecThis systematic review supports the application of local treatment for treating HCC oligometastases.tively. Grade 5 toxicity has not yet been reported.

CONCLUSIONS

This systematic review supports the application of local treatment for treating HCC oligometastases.

The Impact of Psychological Factors on the Asymmetry of Stock Market Volatility in China—An Empirical Study Based on EGARCH Model
Authors: Yang Tao , Su Yanan
Published: May 2023

The asymmetry of stock market volatility has existed for a long time. Most of the early scholars’ research on this phenomenon is based on the assumption of efficient market. In recent years, with the development and deepening of behavioral finance theory, psychological factors have been added to the research process as an important variable to better explain the asymmetry of stock market volatility. Therefore, on the basis of this analysis, this paper uses the basic theories of overconfidence, disposal effect, herding effect and framing effect of behavioral finance to analyze the impact of different psychological conditions on stock market volatility. This paper collects all the closing price data of the Shanghai and Shenzhen 300 index, and processes the logarithmic rate of return, then introduces the proxy variable turnover rate of psychological factors into the mean equation of EGARCH model, establishes a modified EGARCH model, and obtains the empirical results that psychological factors do have an impact on the asymmetry of volatility in China’s stock market. It is concluded that: first, there is asymmetry of volatility in China’s stock market, Investors will respond significantly more to bad news than to good news. Second, when investors are hit by bad news, their expectations for the future become worse, which will increase the turnover rate and finally obtain a lower yield; When investors are hit by good news, their expectations for the future become better, which will reduce the turnover rate and finally obtain a higher yield. Finally, according to these two conclusions, positive and feasible suggestions are given.

An Examination of the Principles of the Rule of Law and Their Application in Islam
Authors: Balogun Yisa Olorunda
Published: May 2023

A lot of works written on the Rule of Law are without Islamic connotations. The ones with Islamic viewpoints are limited. This article is therefore written to supplement the existing literature on the concept. The paper adopted a qualitative approach and its data was based on secondary sources and content analysis of relevant documents. The article harnesses the available information in the Shar’īah to justify the respect that Islam has for the Rule of Law. In doing this, the researcher examined the various clarifications of law and the Rule of Law, the principles of the Rule of Law and the extent to which these principles are applicable in Islam. It was found out that despite the efforts of Shar’āh and various scholars to sustain the ideal application of the Rule of Law, the concept is still facing numerous challenges, among which are poverty and ignorance, immunities to certain individuals and lack of independence of the judiciary.

3D-ВИЗУАЛИЗАЦИЯ ЭРИТРОЦИТОВ МЕТОДАМИ АТОМНО-СИЛОВОЙ МИКРОСКОПИИ
Authors: Трухова А.А. , Ахметова А.И. , Яминский И.В.
Published: May 2023

Эритроциты являются одним из любимых объектов исследования в зондовой микроскопии. Во-первых, они легкодоступны, не требуют долгой и сложной пробоподготовки и, что самое главное, изобилуют отличительными особенностями, которые можно применять в клинической диагностике. Когда эритроциты циркулируют в крови, им необходимо проходить через узкие просветы капилляров, намного меньшие, чем размер их собственного поперечного сечения. Упругие свойства мембраны эритроцитов позволяют им проходить по кровяному руслу и доставлять необходимые вещества. Отношение площади поверхности к объему, вязкость цитоплазмы и внутренняя деформируемость мембран влияют на способность эритроцитов трансформироваться и проходить через узкие промежутки. Поэтому морфологические, структурные и физические характеристики клеток крови приобретают все более важное значение при исследовании различных заболеваний или оценке риска их развития.
TO THE QUESTION OF THE TEACHING OF THE DISCIPLINE “THE FORMATION AND DEVELOPMENT OF THE ORGANS AND INSTITUTIONS OF JUSTICE”
Authors: Stepanova N. Yu.
Published: May 2023

Recently, there has been a tendency to expand the powers of the judiciary. Justice refers to justice as well as the system of judicial institutions. As law enforcement agencies, the justice authorities ensure the implementation of State policy in the legal sphere and the execution of court decisions. They play an important role in creating favourable conditions for the effective functioning of the power structures of the rule of law. The article deals with the teaching of the discipline “Formation and development of judicial bodies and institutions”. A short historiographic overview is presented. Particular attention is paid to considering the role of the use of sources in the study of the educational discipline “Formation and development of judicial bodies and institutions”, the importance of students knowing historical and legal sources in the discipline is emphasized.

ENCODING AND TRANSCODING OF TRANSCRIPTIONS OF THE HISTORICAL CORPUS “MANUSCRIPT”
Authors: Baranov V. A. , Gnutikov R. M. , Zinatshin K. I.
Published: May 2023

The article considers capabilities of using Cyrillic blocks of the Unicode Standard for the purpose of creating transcriptions, which would represent graphics of medieval Slavonic manuscripts. In addition, much attention is given to the fact that the Unicode Standard provides variants of Cyrillic letters, which means that one can accurately enough record graphic features of manuscripts. However, some variants of certain letters are still missing, and that is why there exists a need to use additional agreements of character encoding, which code points are placed in special blocks and Private Use Areas and not in standard ranges of Unicode. The Manuscript - a historical corpus - is the example of a big machine-readable collection of medieval Slavonic manuscripts. It was created on the base of Oracle DBMS with the use of a specialized system of codes and fonts. Transference of the corpus to other technological platforms or usage of external software (including separate texts, parts of corpora, selections) for analysis of linguistic data would be possible only after downloaded files are recoded to the Unicode Standard. A comparative analysis of the character blocks used in the corpus and in the current version 14.0 of the Unicode Standard leads to the conclusion that recoding either results in losses of graphic features or requires usage of a supplementary set of varying characters with code points of Private Use Areas. Instances when there are two or more characters of the Unicode Standard that correspond to one recoded character of the Manuscript are analyzed. It is also stated that numerous ligatures and certain singular graphemes are missing in the standard blocks and in the blocks of Private Use Areas.
LANGUAGE ORIENTATION AS AN ASPECT OF HUMAN ACTIVITY
Authors: Nekipelova I. M.
Published: May 2023

The article is devoted to the research of a phenomenon of language orientation as aspect of human's language activity. The research revealed that language, being a phenomenon of human activity, exists as a set of individual subjective languages (private languages) and as universal objective language (general language). A codified and conventional model is general language; the set of individual ideas about language are private languages. The research showed that correlation between general and private languages forms individual's language experience. As a result of received and comprehended language experience the language orientation of language personality is formed. In turn, society exerts influence the personality by its language orientation in language area. The author determined that vectors of orientation are elements of inner permissive language structure of personality, formed and fixed by individual's language experience in the course of language socialization and social adaptation. Finally, it was concluded that language orientation presupposes the differentiation of language material to relevant and irrelevant. It may be conscious or unconscious. As a result, language experience and language orientation organize and control human's cogitative activity. It is important to understand that consistency and integrity of language orientation system are indications of stability and autonomy of language personality.

Green Leaf Disease Detection
Authors: Saji Alby
Published: May 2023

Abstract: Because it feeds humanity, creates jobs, and directly supports national economic progress, agriculture is the backbone of the country. Identification of plant diseases is very crucial in agriculture. The increasing use of pesticides and sprays nowadays has led to a wide range of diseases affecting plants. Early disease detection would help farmers save more harvests if the infections could be stopped. Plants can be saved if rotting spots are discovered early. Automatic plant disease detection not only saves time but also provides greater accuracy. Plant production is decreased by improper disease detection. Here, we use image processing techniques to identify a few common plant illnesses. First, we take the image of the plant anduse image processing to identify it. This project is being implemented using Python.
Transportation Payment by using Smart Card
Authors: Suki Jidnyasa
Published: May 2023

Abstract: It is often notice in a public transportation that the conductor face a lot of problems in collecting the fare from the passengers. Money handling and returning the access amount to the passengers after deducting the fare amount, inspecting a travel pass becomes complex when the congestion that is the number of passengers are very large in numbers is high and this complexity cannot be managed effectively. Productivity in the urban areas is much dependent on how efficient the transport system is to move a travelling groups from multiple origins to multiple destinations. Importance of this smart system helps in enhancing the process and increases the efficiency of fare collection and congestion management. The system consist of a scanner system to scan the smart card which can be topped up by the recharge centers and GPS module to track the distance travel by the passengers. Thus amount gets deducted from the passenger’s smart card for only the distance travel. This enhances the proper utilization of the resources , reduces time and serves to be economic for the citizens.

Abstract: The Film Industry is one of the largest industries in the world that has a huge flowof capital flowing through it. Lots of movies release across the world through differentmediums whether theatrically or through OTT etc. But very few achieve the desired success. The unpredictability of the film industry and the huge amount of capital and workforce investment which is required in film production makes film makers nervous and they require amedium which will assure them about the prediction of success of their movie and also the target audience of their movie before its release, so that they can take right decisions about their project in time. In this model, the movie's success will be predicted and also the targetage group will be determined which can be targeted in attracting the audience by correct marketing and film making policies. Two Imdb datasets are utilized in the model respectively for prediction of success of the movie and its target audience. For predicting the success of themovie we have used Stochastic Gradient Descent Classifier Algorithm.

Published: May 2023

A two degree-of-freedom vibration isolation system with
magneto-rheological damper (MRVIS) is analyzed. Under the harmonic
excitation, the nonlinear behaviors are discovered. With the excitation
frequency increased, the period-doubling bifurcation and saddle node
bifurcation, route to chaos are found. Then, the system returns to
steady state through the route out of chaos, with inverse
period-doubling bifurcation. Furthermore, a sliding mode controller
through tracking the error between actual and ideal state system, is
proposed to suppress the increasing amplitude of the system caused by
the chaos. Both the calculation and experiment show that the chaotic
motion is effectively repressed.
Digital soil mapping enables informed decisions to conserve soils within protected areas
Authors: M George van Zijl , Tol Johan van
Published: May 2023

Protected areas are often regarded as pristine land, but in reality,
they require rehabilitation and effective management to prevent
increased land degradation. Soil management requires soil maps to make
informed decisions, which is difficult to create in protected areas due
to the large size of land, limited accessibility, little available soil
data and limited budgets of such projects. In this paper a hybrid expert
knowledge and machine learning digital soil mapping (DSM) method is used
to create such maps for Benfontein, a 9900 ha protected area in the
semi-arid region of South Africa. The hybrid method uses soil landscape
rules to determine virtual soil observations which is added to the
training observations used in a machine learning algorithm to create a
soil associations map. Soil properties were assigned to each soil class
at the 0.1, 0.5 and 0.9 percentile level, to indicate the range of
properties at an 80% certainty. The soil maps were interpreted to
indicate soil carbon sequestration potential, soil erodibility and
off-road driving potential. The soil association map was acceptable as
it achieved a kappa value of 0.69. Additionally, it was determined that
the site has a large potential for carbon sequestration, the soils are
relatively stable against water erosion, and off-road driving should be
prohibited on approximately half of the area. The results indicate that
the hybrid DSM method is viable to create useful soil maps to inform
management decisions in the unique settings of protected areas.

The much hyped Artificial Intelligence (AI) model known as chat
generative pre-trained transformer ( Chat GPT), developed by
Open AI can have far-reaching benefits for pathologists saving time so
that they can devote their time to more meaningful work. Generative AI
is a special class of AI model, that based on patterns and structures
learned from existing data can create new data. However, certain hurdles
have to be taken care of like integrating ChatGPT with image analysis
which will revolutionize the field of pathology by providing assistance
with diagnostic accuracy and precision. Generation of meaningful
insights from the textual information provided by ChatGPT can be
possible by the platform which should have the capability of processing
different types of image data, such as medical images, and pathology
slides. Due consideration should be given to ethical and legal issues
including bias.
