Purpose: simulation of the filtration process from an irrigation canal made in an earthen channel. Materials and methods. One of the most common methods in the waterworks construction and operation is the filtration process modeling. In practice, the use of mathematical modeling based on the use of mathematical analogies of various physical processes, which are described by the same differential equations, is widespread. The electric analogy method (EGDA) is based on the analogy between the groundwater velocity and the electrical current flow and allows solving various filtration problems on models of electrically conductive materials. The purpose of modeling the groundwater velocity using the EGDA method is to develop a model similar to a full-scale object, for studying the ongoing filtration processes with its help. Results. A flow net and a filtration velocity profile which were used to study free filtration from a canal in an earthen channel were constructed. As a result of the study, the specific filtration flow rate, filtration rate were determined and a comparison with the values obtained by calculation was made. Comparison of the results obtained from the flow net with the calculation formula showed that their values coincide with an error of 1.26 %. The specific flow rate determined by the calculation method coincides with the flow net value for the selected belt of equal pressure with an error of 2.8 %. Conclusions: the EGDA method allows determine effectively the seepage water losses from the canal, however, when quantifying the seepage flow, it gives more significant errors due to the complexity of complete recording when modeling the real conditions of the object under consideration.

Purpose: to determine patterns of formation of hydrographic network elements depending on the melt-and rainwater runoff and soil losses. Materials and methods. The studies were carried out in the upper reaches of the Bolshoy Log gully system, which is a part of the land use of the experimental farm “Polevoy” of the Federal Rostov Agrarian Research Center, with an area of 2070 hectares, of which more than 70 % is arable land. Soils are ordinary chernozems of varying degrees of erosion. The standard methods of research and the method of pins were used on runoff plots. Results. Within the catchment area, the amount of runoff and hydraulic indicators of water courses are greatly influenced by the agricultural background and the soil surface condition from which meltwater flows, and the intensity of erosion processes is influenced by the depth of soil freezing, the moisture content of topsoil, water storage in snow, snowmelt intensity. The water sprays are concentrated along the gullies, where the soil is washed out over time, and they pass into the category of hollows, then into ravines and gullies, forming a hydrographic network in the gully-ravine catchment area. The most intensive meltwater runoff was observed over the years: in 1988 – 33.8 mm, 2003 – 63.9 mm, 2006 – 24.6 mm, 2014 – 14.3 mm, 2017 – 19.3 mm, 2023 – 10–14 mm. In the variants with reclamation protective forest plantations and hydraulic structures, the runoff was 5–12 mm less than in the control and it retained in the forest belt. The mathematical data analysis made it possible to determine the relationship between the runoff rate and soil loss in the gully-ravine catchment, depending on the distance from the watershed. Conclusions. On the gully-ravine catchment, the sheet wash smoothly turns into a linear one and forms hollows and valleys. The final link of the catchment area are ravines and gullies. During the peak periods of meltwaters, the water flow velocity on flat sections of the slope is 0.33–0.46 m/s, and along the hollows – 0.57–0.83 m/s.

The methodological basis of the study was systematic, comparative, heuristic and mathematical-statistical approaches. The implemented methods of formalized decision-making support include mathematical optimization, as well as forecasting the expected result, including on the basis of artificial intelligence methods. Results. Methodological approaches to planning system water distribution under conditions of water scarcity or under limited production and economic conditions are considered. The analysis of the methodology on managerial decision-making support based on artificial intelligence methods is carried out. The main requirements for the priority methods of information support of control actions are determined, including their practical applicability, rationality of the planned results, as well as ensuring sufficient accuracy of solving the optimization problem. Criteria for optimizing water distribution planning under conditions of low-water irrigation source or with limited production and economic conditions are systematized. It has been determined that using mathematical modeling and artificial intelligence contributes to the development of information technologies for optimizing water distribution. A basic economic-mathematical model including the gross output as a target function has been developed and tested. Conclusions. Testing the model on the materials of the Gorodischenskaya irrigation system data showed the possibility of increasing production up to 78.8 thousand rubles/ha. This is achieved by improving the quality of planning and management of water distribution under the conditions of water scarcity in the Lower Volga region.

Reconstruction of Flow Rate History Using Linear Regression
Authors: Negash Berihun Mamo , Poon Chee Him , Vasant Pandian M.
Published: August 2023

Long-term pressure and flow rate history are important for reservoir characterization and reservoir management. However, a complete set of these data are often not available due to numerous technical difficulties. Currently, datasets with missing information are omitted and not considered for further analysis. In this study, we use machine learning algorithm via linear regression for flow rate history reconstruction. Only few studies have demonstrated the application of linear regression for well testing purposes. However, pressure and flow rate data in a producing field are comparatively longer and more complex. A combination of feature extraction and linear regression was applied for long term flow rate history reconstruction. The dataset used to evaluate the performance of the proposed method was obtained from a real producing field. This study indicated the high performance of linear regression at estimating missing flow rate history using available pressure readings in the dataset. Although linear regression has the benefits of high interpretability and fast computation time, it fails to perform well in reconstructing flow rate history when there is a significant degree of variation in the flow rate and pressure data.

Estimating the Radius of Investigation and Drainage Area by Reservoir Simulation
Authors: Sajali Fadzli , Lee Jang Hyun , Mahyuddin Naqiuddin
Published: August 2023

The radius of investigation is still ambiguous and there is uncertainty in radius of investigation calculation. Every changes of pressure in the reservoir will change the radius of investigation. Thus, these variations will make the maximum radius of investigation difficult to define. To analyze this uncertainty, the pressure changes in a reservoir is evaluated by using the Ei-Function equation to plot the pressure profile which is pressure versus distance of the well graph. Furthermore, the pressure profile graph can be used to set a cut off of pressure difference at the end of transient effect that can be defined as maximum radius of investigation. This project required Matlab software for analytical approach and Eclipse Simulator software for numerical approach. The numerical method is used to prove the analytical method. The analytical method will provide the pressure profile which indicate the pressure of reservoir reading further away from the well. Similarly, the numerical method will generate the pressure of reservoir numerically to indicate the same as analytical method. The homogeneous reservoir is used to analyze this ambiguity where the manipulated variable is the flowrate and production time. The preliminary interpretation showed that different flowrate will not affect the radius of investigation while different production time will affect the radius of investigation.

On the Consistency of Conjectural Variations as the Solution of a Two-Stage Game
Authors: Kalashnikov Viacheslav , Kalashnykova Nataliya , Flores Muñiz José Guadalupe
Published: August 2023

In our previous research publications, we established a significant connection between consistent conjectures and those of Cournot–Nash. We developed a new mathematical model based on a two-stage game specifically for the oligopolistic market. In this two-stage game, the role of the players correspond to the agents operating within the oligopoly, and the role of their game strategies is played by the conjectures accepted by these agents. We successfully demonstrated that if a Nash equilibrium exists within this two-stage game, it aligns with one of the consistent equilibria observed in the oligopolistic market. In our proposed study, we aim to identify the specific conditions through which we can substantiate the consistency of the equilibrium within the oligopoly by means of the Nash equilibrium in this two-stage game. This finding is of particular significance as it provides a pathway to expand the notion of consistency for the conjectural variations to mathematical models that differ from the oligopolistic market. Examples of such models include financial markets, the natural gas industry, the oil industry, and various others.
The پاکستان میں فرقہ پرستی اور تکفیری رجحان:وجوہات، اثرات اور حل
Authors: Rao Muhammad Atif Aslam , Ali Anwar
Published: August 2023

Though sectarianism and the violence carried out in its name have plagued the country since its inception but the divisive trend saw a systematic and unusual growth since 1980s. Sectarianism is generally taken to mean insistence on an exclusivist doctrine and attempts by its adherents to impose their version of faith on the rest of society by any means, violent included. Unfortunately, the engineered menace did not disappear with the defeat of Soviet Union and containment of Iran and took roots in society, exacerbating intolerance between rival religious groups to such an extent that one group considered the other as an apostate and recklessly declared it as such in public. It was in spite of the fact that the Prophet (peace be upon him) had proclaimed in unequivocal terms that difference of opinion (among jurists) was a blessing. One can find innumerable examples throughout Islamic history attesting to the fact how caliphs, successors, their followers and Imams of different schools of thought showed respect to each others’ opinions and none passed verdicts of apostasy against the other. This paper presents a contemporary analysis of sectarianism in Pakistan by contextualizing its causes, pointing out major fault-lines and assessing its impact on people at large with major focus on the resurgence and cancerous growth of the practice of Takfīr. The research recommends that an inter-confessional informed dialogue in a peaceful environment is the first and foremost step required to break the ice and teach tolerance to the many groups who perceive each other as sworn enemies. This first step may follow further actions to keep temperatures in check, build confidence and finally bring the sects’ representatives to accept an end to practice of Takfīr and establishment of an atmosphere of peaceful coexistence and tolerance.
سزائے موت : پاکستان پر عائد عالمی ذمہ داری،تحقیقی جائزہ
Authors: Kakar Muhammad Sadiq , Zaidi Syeda Salva Ahmed
Published: August 2023

This paper examines the compatibility of international human rights law and Islamic law regarding capital punishment in the Pakistani context. Despite the adoption of the Second Optional Protocol to the International Covenant on Civil and Political Rights (ICCPR) by the United Nations in 1989, which aimed to completely abolish the death penalty worldwide, countries continued to practice capital punishment for several offences. The paper highlights Pakistani laws and discusses the challenges that hinder the country from ratifying the Optional Protocol. The paper suggests an adaptable solution to the issue by analysing the restrictions of death penalty under Islamic Law. Principally, both Islamic law and international human rights law consider the protection of life and endurance of justice to be very significant, but the conflict, which has raised the discrepancy is in the priorities between the interests of the individual and the public at large. This paper presents a comprehensive and impartial study to bridge the gap between International Human Rights Law and Pakistani domestic laws. Moreover, ICCPR also requires minimal death penalties in a legal system, it is mandatory for Pakistan, being a member party, to curtail the punishment in the domestic legal system. It seeks to examine the challenges that arise when reconciling these two systems and propose possible solutions.
جنم مخالف (Anti-Natalism)نظریہ کا تعارف،تاریخی ارتقاء اور بنیادی مستدلات
Authors: Farhad Ali  , Aziz ur Rehman
Published: August 2023

Anti-Natalism is a primitive doctrine and nobody has a certain knowledge about its beginning. However, the ancient Greek and Buddhist civilizations claim some signs of the existence of this doctrine and its followers. Anti-Natalism is a philosophy which condemns the life and holds annihilation as superior in comparison. The believers of this doctrine have asked the people to stop reproducing human beings. They have produced various arguments in favor of their demand to forsake the birth process. This research article attempts to focus on the introduction, historical evolution and fundamental arguments of the doctrine of Anti-Natalism. This research shows that Seana Valentine Shiffirn argues that the undertaking of the birth process makes no sense since we are unable to question the person to be born about his consent prior to his birth. David Benatar is of the opinion that we have no moral justification to undergo the birth process because it results in a huge loss for the person to be born. An important name in the list of the advocates of Anti-Natalism doctrine is that of Schopenhauer who invalidates the birth process on pessimistic grounds. Similarly, Karem Akerma pleaded against the birth process on the basis of Ethical Vegetarianism. The basic concept of Ethical Vegetarianism is that all those activities that are harmful for animals should be abandoned. The key point of Dr Gerald Harrison's argument is that man is the most disastrous animal on planet earth so mankind should be eliminated from this planet which is practically possible only if the men of this age stop reproducing themselves.

Exploiting customer insights plays a key role in the long-term development strategy of every business, which strongly supports them in building trust with customers and enhancing competitive advantages. Especially in the period of rapid growth of technology, as there is a significant increase in online users, all the interactions and comments become more important in extracting valuable insights into customer behaviours and emotions. Our research aims to conduct sentiment analysis on comments in mobile commerce apps , then classify them into positive or negative sentiment, based on a hybrid approach that combines supervised machine learning methods and natural language processing techniques; at the same time, evaluating the model performance through the Confusion Matrix to ensure the reliability of the results. The study experimented on a proposed model with 04 machine learning methods including Naive Bayes, SVM, Random Forest and Logistic Regression on more than 935,000 comments collected from 04 popular mobile commerce apps in Vietnam (Tiki, Shopee, Lazada and Sendo). The experiment categorised positive and negative views with high accuracies of 91%, expressed by reports and charts that reflect customer trends and feelings. Moreover, the study also brings new and deeper perspectives on customer behaviours, assisting administrators to detect the strengths and weaknesses of services and apps, thereby improving user experience. Based on the research results, E-commerce businesses can analyse market trends and explore customers' needs and interests to develop effective product and service development strategies.

The purpose of the work is to study the possibility of improving the sowing properties of safflower seeds due to their separation on a vibrating seed cleaning machine with non-perforated friction working surfaces. The article presents the results of cleaning and sorting of the seed mixture of dyed safflower on a vibrating seed cleaning machine after preliminary separation on existing grain cleaning machines. For one pass of the non-standard safflower seed mixture through a vibrating seed cleaning machine, 91.94% (from the mass of the starting material) of the main crop seeds with high sowing rates, which meets the requirements of the state standard of Ukraine, was obtained. The separation of safflower dye seeds on a vibrating seed cleaning machine with the selection of full-fledged seed material for sowing ensures an increase in the main indicators of the sowing qualities of the seeds, which increases the yield of this crop. Experimental studies have established the feasibility of using a vibrating seed cleaning machine with non-perforated working surfaces for further cleaning of seed mixtures of dyeing safflower with simultaneous sorting of the main crop seeds. The machine can be recommended as part of technological lines for post-harvest processing of seed mixtures of safflower for dyeing.

The present study aims to determine the effect of the early warning system (EWS) on the preparedness of hospitals in emergencies and disasters. This study was a quasi-experimental study conducted with two groups. One month, and then three months after determining hospital preparedness (HP) through the world health organization standard checklist, a seminar and two-session workshop as intervention, and installing a flowchart for activating the EWS in important hospital sections, HP was reevaluated and analyzed by longitudinal descriptive statistics. A total of 30 nurses were included in the present research. The findings suggested the preparedness score of intervention hospitals before the intervention, one month, and three months after that the biggest change occurred in the communication sector with a 10-point increase; the smallest change occurred in the continuity of essential services and port-disaster recovery; the overall score of HP changed from being poor before the intervention to medium after three months (P<0.05). In the control hospital, human resources had the biggest change with a 4-point increase; command and control, communications, continuity of essential services, and post-disaster recovery had the smallest change with a 1-point increase; the overall HP was poor and remained poor despite the increase in scores (P<0.05). In sum, the outcomes of this study imply that the intervention hospital has a moderate level of disaster preparedness. The findings of this study highlight the importance of instituting an EWS in all hospitals across the country to enhance readiness for calamities. Hence, implementing EWS in similar conditions in other hospitals in the country can improve the preparedness of these hospitals in emergencies and disasters to a great extent.
