This study details the optimal characteristics of these systems to design an ideal pumping solution that maximizes agricultural productivity while reducing costs and ecological footprint. The designed system is an off-grid solar pump control device equipped with an MPPT controller for 24V DC photovoltaic panels operating within a 30-48V range. This system operates directly under solar irradiation, eliminating the need for energy storage. A major innovation of this system is its ability to regulate the filling of the water tank based on the measured water flow. When sensors detect low flow, the system automatically activates the water tank recharge and stops its activity when the flow reaches a predetermined threshold, thus optimizing the efficiency of water use for irrigation. The advanced architecture of the system integrates controllers capable of compensating for solar power fluctuations and intelligent sensors to automate the pumping process according to crop water needs. This systemic approach offers a robust and sustainable method to improve water management in agricultural operations, contributing to sustainable development goals and resilience to climate change.

Earned Value Management (EVM) is a project management tool primarily used in engineering and project management to assess performance in terms of cost and schedule. Earned Value Management/Scheduling systems (EVM/ES) have been fundamental in project control, providing key metrics that measure deviations between planned and actual performance in terms of time and cost. However, its application as a project control technique is not very common in Mexico. In this article, EVM was applied to the intralogistics improvement of a manufacturing process in the automotive sector located in Aguascalientes, Mexico. The case study concluded in February 2024 and includes the project scope, scheduling charts, physical progress reports, and budgeted versus actual cost reports. The aim of this article is to provide practical evidence on how to apply EVM in manufacturing projects in Mexico. This will enable project professionals to more effectively utilize EVM for schedule and cost control in their manufacturing projects, with a specific emphasis on intralogistics.

Understanding Oil Formation Volume Factor βo is crucial for effective oil field development, impacting well performance analysis, reservoir simulation, and production engineering calculations. Traditionally, βo is determined through costly and time-consuming laboratory tests, prompting the need for accurate mathematical correlations. Existing correlations such as Vasquez-Beggs, Standing-Glaso, and others have been widely used but show varying degrees of accuracy across different operating conditions. In this study, these correlations were evaluated against 95 datasets of experimental βo data for Sudanese crude oils. Statistical analysis revealed that Vasquez-Beggs and Standing- Glaso models performed best, with average absolute errors of 3.4219 and 3.4477, and correlation coefficients of 0.7563 and 0.7213 respectively. Motivated by the limitations of existing correlations, a new ap- proach using Polynomial Neural Networks (PNN) was developed. This model utilized reservoir temperature, gas gravity, gas oil ratio, and API as input parameters, trained on 70% of the dataset and tested on the remaining 30%. The PNN model exhibited superior predictive performance with a relative average absolute error of 2.8607 and a correlation coefficient of 0.9080. This study contributes a robust predictive tool for estimating βo in Sudanese oil fields, offering enhanced accuracy over traditional correlations and facilitating more reliable reservoir management decisions.

The COVID-19 epidemic has created unprecedented challenges for global economies, affecting every industry, including the building construction industry in Nepal as well. This research aims to examine the impact of the COVID-19 epidemic on the building construction industry in Nepal. This study examines institutional, psychological, individual, operational, contractual, and financial factors. To achieve the objective, data were collected from 330 Nepalese construction professionals using a structured Likert scale questionnaire and analyzed with Smart PLS version 3 software for partial least squares structural equation modeling. The reliability and validity of both the measurement and structural models were tested and found satisfactory. All six factors were found to be significant at a 5% level of significance. Among all factors, the institutional factor was found as the most significant factor with a t-value of 7.654 and a beta value of 0.679, emphasizing the crucial role of institutional support in Nepal's building construction industry. The psychological factor also emerged as the second most significant influential factor (t value: 6.087, beta value: 0.463), underscoring the profound effect on the mental well-being of professionals in the field. The finding highlights the critical importance of institutional support and the profound influence of psychological factors on the well-being of construction professionals, necessitating targeted interventions to support the industry's recovery and resilience.

Security monitoring is a crucial aspect of cybersecurity and a prong of organizational cybersecurity policies. It is achieved primarily using SIEM tools supported by logs ingested from intrusion detection tools and other security solutions. SIEM tools generate alerts of varying severities when detection rules identify anomalies or possible security incidents after analysis of ingested logs. These alerts need to be investigated, but due to the volume of alerts generated and the limited monitoring manhours, it is important to prioritize which security alerts are investigated first. This paper presents a sliding window technique for prioritizing security events by computing a priority value using the severity of previous alerts, alert entities, and criticality ratings. Findings from the experiment show that this approach improves the prioritization of security alerts with severe and medium alerts affecting critical systems prioritized over low, high, and critical alerts affecting non-critical systems. This work can potentially streamline and enhance the efficiency of security monitoring operations.
In today's rapidly evolving technological landscape, artificial intelligence (AI) and machine learning (ML) stand out as pivotal elements. Their integration into the financial domain is particularly noteworthy, revolutionizing the sector through continuous advancements. With each passing day, these technologies introduce more sophisticated techniques to bolster financial intelligence. This necessitates a comprehensive evaluation of their influence on finance, examining both the current enhancements and the future possibilities they present. It’s crucial to assess the transformative power of AI and ML in finance and to anticipate the emerging opportunities they may unveil.

The prediction model equation of a draught force of animal-drawn Mouldboard plough has several advantages in improving tillage performance in smallholder farming systems. These include fully utilizing input data for implement designers and extension workers, proper usage of draught animals, and minimizing operator tragedy. A 1 x 3 x 3 factorial experimental design was arranged in a Randomized Complete Design (RCD) on three blocks of test plots each measuring 25 m x 80 m to generate input parameters for predicting the draught of animal-drawn mouldboard plough on the sandy loam soils at Yola. The model input parameters include implement mass, operation speed, operation depth, soil moisture content, and bulk density. A pair of oxen weighing 560 kg was used as a power source. The highest mean draught values of 436.40 N and the lowest of 381.47 N were obtained at a speed and depth combination of 1.25 m/s and 0.183 m and 0.69 m/s and 0.083 m respectively. A mathematical model with a correlation between the measured and predicted r2 value of 0.9683 was developed using the concept of Buckingham's Pi theorem. The model developed effectively predicted draught for animal implements by 96.83 %. A paired t-test revealed no significant difference between the measured and the predicted values at 0.05 significant levels. The result showed that a developed mathematical equation can effectively predict the draught force of mouldboard plough in sandy loam soil.
