Bakery nutritional products are limited in a global market considering the consumer preferences. Recent years have seen a surge in publications, especially in India and Latin America, reflecting nutritional and development of new products challenge, however, there are project management tools that could help in the development of new products because proactive approaches are necessary to navigate bakery product development complexities. Malnutrition and obesity pose global health challenges, elevating the importance of providing more nutritious bakery options. This systematic literature review explores the intersection of bakery product development with project management methodologies, emphasizing nutritional enhancement and consumer acceptance by the analysis of 69 articles from 2013 through 2024 from prestigious database such as Scopus and Redalyc to generate an overview for new future projects related to enhance the sector in Mexico. The study identifies multiple opportunities in bakery product research. The most researched products in this area are bread, cake, cookies and tortillas compared to pasta, pizza, pudding, waffles, etc. Additionally, only a quarter of articles explore new commercial prototypes, indicating significant potential for further development in this area.
考虑到消费者的偏好,焙烤营养产品在全球市场上是有限的。近年来,有关营养和新产品开发挑战的出版物激增,尤其是在印度和拉丁美洲,不过,有一些项目管理工具可以帮助开发新产品,因为要应对烘焙产品开发的复杂性,必须采取积极主动的方法。营养不良和肥胖对全球健康构成了挑战,因此提供更多营养丰富的烘焙食品就显得尤为重要。本系统性文献综述探讨了烘焙产品开发与项目管理方法的交叉点,通过分析 Scopus 和 Redalyc 等著名数据库中 2013 年至 2024 年的 69 篇文章,强调了营养强化和消费者接受度,从而为墨西哥未来与该行业相关的新项目提供一个概览。研究发现了烘焙产品研究的多种机遇。与意大利面、披萨、布丁、华夫饼等相比,该领域研究最多的产品是面包、蛋糕、饼干和玉米饼。此外,只有四分之一的文章探讨了新的商业原型,这表明该领域的进一步发展潜力巨大。

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.
了解油层体积系数 βo 对于有效开发油田至关重要,它影响着油井性能分析、储层模拟和生产工程计算。传统上,βo 是通过成本高、耗时长的实验室测试确定的,因此需要精确的数学相关性。现有的相关方法,如 Vasquez-Beggs、Standing-Glaso 等,已被广泛使用,但在不同的作业条件下显示出不同程度的准确性。在本研究中,针对苏丹原油的 95 个实验 βo 数据集对这些相关性进行了评估。统计分析表明,Vasquez-Beggs 和 Standing- Glaso 模型表现最佳,平均绝对误差分别为 3.4219 和 3.4477,相关系数分别为 0.7563 和 0.7213。鉴于现有相关性的局限性,开发了一种使用多项式神经网络(PNN)的新方法。该模型利用储层温度、天然气重力、气油比和 API 作为输入参数,在 70% 的数据集上进行训练,并在其余 30% 的数据集上进行测试。PNN 模型显示出卓越的预测性能,相对平均绝对误差为 2.8607,相关系数为 0.9080。这项研究为估算苏丹油田的 βo 提供了一种稳健的预测工具,与传统的相关性相比,它具有更高的准确性,有助于做出更可靠的油藏管理决策。

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.
挣值管理(EVM)是一种项目管理工具,主要用于工程和项目管理,以评估成本和进度方面的绩效。挣值管理/日程安排系统(EVM/ES)是项目控制的基础,它提供了衡量时间和成本方面计划绩效与实际绩效之间偏差的关键指标。然而,在墨西哥,将其作为项目控制技术的应用并不普遍。在本文中,EVM 被应用于墨西哥阿瓜斯卡连特斯汽车行业内部物流的改进。案例研究于 2024 年 2 月结束,包括项目范围、进度表、实际进度报告以及预算与实际成本报告。本文旨在提供如何在墨西哥制造业项目中应用 EVM 的实用证据。这将使项目专业人员在其制造项目中更有效地利用 EVM 进行进度和成本控制,并特别强调内部物流。

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.
本研究详细介绍了这些系统的最佳特性,从而设计出一种理想的泵送解决方案,在最大限度提高农业生产率的同时降低成本,减少生态足迹。所设计的系统是一种离网太阳能水泵控制装置,配备了一个 MPPT 控制器,适用于在 30-48V 范围内工作的 24V 直流光伏电池板。该系统直接在太阳辐照下运行,无需储能。该系统的一大创新是能够根据测量到的水流量调节水箱的注水量。当传感器检测到低流量时,系统会自动启动水箱补水,并在流量达到预定阈值时停止补水,从而优化灌溉用水的效率。该系统的先进结构集成了能够补偿太阳能波动的控制器和智能传感器,可根据作物的用水需求自动执行抽水过程。这种系统方法为改善农业生产中的水资源管理提供了一种稳健而可持续的方法,有助于实现可持续发展目标和抵御气候变化。

This paper analyses vibration of uniform flexible simply supported rectangular isotropic beam under large deformation with uniformly distributed mass elements. The method of equivalent pseudolinear systems was employed. The deformation of the beam was assumed to be large and the beam was also assumed to be inextensible. The expressions for elastic and nonlinear bending moments were determined. The numerical values of horizontal displacements of the movable support, and the equivalent lengths at various depth-to-breadth (aspect) ratios were determined. The corresponding equivalent pseudolinear systems for various nonlinear bending moment diagrams at various aspect ratios were determined. Consequently the concentrated loads yielding the equivalent pseudolinear systems were converted to point masses using the gravitational acceleration; and subsequently a unit load system was applied successively and independently at each mass point. The Vereshchagin’s method was applied to determine the displacements for canonical equations of motion. Non-trivial solution of the canonical equations at each aspect ratio was sought for the desired eigenvalues. The first mode frequencies at aspect ratios, β = 1.00 and β = 1.25 are complex eigenvalues. Also the natural frequencies exhibit hard-spring type with aspect ratios; and the fundamental frequencies for all the aspect ratios are at seventh mode. Conclusively, the dynamic stability of the flexible rectangular beam of 0.25m-breadth and 15m-undeformed length is not guaranteed when the aspect ratio is less than or equal to 1.25. It is also concluded that deepness of the flexible rectangular beam loaded with uniformly distributed mass elements influences the vibratory characteristics.
本文分析了带有均匀分布质量元素的均匀柔性简支矩形各向同性梁在大变形下的振动。采用了等效伪线性系统方法。假定梁的变形很大,同时假定梁是不可拉伸的。确定了弹性弯矩和非线性弯矩的表达式。确定了活动支座水平位移的数值,以及不同深宽(纵横)比下的等效长度。确定了不同纵横比下各种非线性弯矩图的相应等效伪线性系统。随后,利用重力加速度将产生等效假线性系统的集中荷载转换为点质量,并在每个质量点上连续、独立地施加单位荷载系统。韦列沙金方法用于确定典型运动方程的位移。为获得所需的特征值,对每个纵横比的典型方程进行了非三维求解。高宽比为 β = 1.00 和 β = 1.25 时的第一模态频率是复特征值。此外,自然频率随纵横比的变化而呈现出硬弹簧类型;所有纵横比的基频都位于第七模。最后,当纵横比小于或等于 1.25 时,宽度为 0.25 米、长度为 15 米的柔性矩形梁的动态稳定性得不到保证。此外,还得出结论认为,装载均匀分布质量元素的柔性矩形梁的深度会影响振动特性。

This paper investigates the heat transfer of multi-layer coated tools. An analogous coating layer technique is used to compare multi-layered coated tools to mono-layer coating tools and develop a heat transfer model for mono-layered coating tools. The equivalent heat capacity, density, and thermal conductivity of the coating are determined based on the geometric size, initial conditions, and boundary conditions, given the tool rake face temperature. The heat transfer efficiency of the multilayer coating is significantly influenced by the coating layers, the thickness of the layer, and the coating material. The results show that the equivalent coating layer approach is suitable for calculating coating temperature enhancement in the cutting heat transfer. The calculation of cutting temperatures for multilayer-coated tools was conducted and subsequently compared to experimental findings, revealing an error margin of around 10%. The findings of this study indicate that analytical models are also suitable for modelling cutting temperatures in multi- layer coating designs.
本文研究了多层涂层工具的传热问题。通过类比涂层技术,将多层涂层工具与单层涂层工具进行比较,并开发出单层涂层工具的传热模型。根据几何尺寸、初始条件和边界条件,并考虑到工具耙面温度,确定了涂层的等效热容量、密度和热导率。多层涂层的传热效率受涂层层数、涂层厚度和涂层材料的影响很大。结果表明,等效涂层法适用于计算涂层在切削传热中的增温效果。对多层涂层刀具的切削温度进行了计算,随后与实验结果进行了比较,发现误差范围约为 10%。研究结果表明,分析模型也适用于多层涂层设计中的切削温度建模。

An analogous coating layer technique is used to compare multi-layered coated tools to mono-layer coating tools and develop a heat transfer model for mono-layered coating tools. The equivalent heat capacity, density, and thermal conductivity of the coating are determined based on the geometric size, initial conditions, and boundary conditions, given the tool rake face temperature. The heat transfer efficiency of the multilayer coating is significantly influenced by the coating layers, the thickness of the layer, and the coating material. The results show that the equivalent coating layer approach is suitable for calculating coating temperature enhancement in the cutting heat transfer. The calculation of cutting temperatures for multilayer-coated tools was conducted and subsequently compared to experimental findings, revealing an error margin of around 10%.

Community detection is the identification of different communities or groups that exist within a network. This is useful in social network analysis (SNA) or what is great is performing whole network analysis (WNA), where humans interact with others as part of their various communities, but these approaches are not limited to the study of humans. These methods are to investigate any type of node that interacts closely with other nodes, whether those nodes are animals, hashtags, websites, or any other type of node in the network. In this work, we zoom in on communities that exist in a network. Community detection is a clear, concise, and appropriate name for what we are doing. Communities in the network would be worth exploring and understanding for further purposes. There are several methods and different approaches to detect community, but in this paper, I use two efficient methods to detect whole network which are named Louvain Method (LM) and Girvan-Newman Method (GNM). With LM, we can build a fast algorithm that is effective at community detection in massive networks and optimize the algorithm for better results. Using the GNM, a better approach that can identify the least number of edges that could be cut would result in a split network. We could do this by making an algorithm looking for the edges that the greatest number of shortest paths pass through.
社群检测是指识别网络中存在的不同社群或群体。这在社会网络分析(SNA)中非常有用,或者说,在进行全网分析(WNA)时,人类作为其各种社群的一部分与他人互动,但这些方法并不局限于对人类的研究。这些方法可以研究与其他节点密切互动的任何类型的节点,无论这些节点是动物、标签、网站还是网络中的任何其他类型的节点。在这项工作中,我们将放大网络中存在的社群。对于我们的工作而言,"社群检测 "是一个清晰、简洁、恰当的名称。网络中的社群值得我们进一步探索和了解。有多种方法和不同的方式来检测社区,但在本文中,我使用了两种高效的方法来检测整个网络,它们分别被命名为卢万方法(LM)和吉尔万-纽曼方法(GNM)。利用 LM,我们可以建立一种快速算法,在大规模网络中进行有效的社区检测,并优化算法以获得更好的结果。使用 GNM,一种更好的方法可以识别出最少的可切割边,从而分裂网络。我们可以通过寻找最多最短路径通过的边的算法来实现这一点。

Carbon nanotubes and fullerenes offer exceptional mechanical and electrical qualities due to their cylindrical and hollow spherical molecular structures. Their extensive range of applications, which includes field emission displays, impregnated metal composites, battery storage media, and nanoelectronics devices, demonstrates their exceptional adaptability. The combination of simple materials, variable behavior, and simplicity of manufacture makes these materials a focal point of contemporary research. Due to the low bias transmission at a few nanometers, they have a wide range of applications in electronic devices, and finding their potential applications is a complicated process. Due to the fact that the valance and conduction bands are symmetric, they have a straight band gap and can be exploited for optical emission. Three processes, including arc discharge, laser ablation, and chemical vapor deposition, can be used to generate carbon nanotubes (CNTs), although chemical vapor deposition (CVD) is the most used method since it yields CNTs that are more than 98% pure. Multiple chirality of 100% pure MWCNTs results in enhanced optical properties and improved use as a light harvesting material. Using CNT composites and functionalized nanotubes, the dye-sensitized solar cells are constructed. In this brief review, the synthesis of CNT and its application in solar cells are discussed.
碳纳米管和富勒烯因其圆柱形和中空球形分子结构而具有优异的机械和电气性能。它们的应用范围非常广泛,包括场发射显示器、浸渍金属复合材料、电池存储介质和纳米电子器件,这表明它们具有卓越的适应性。简单的材料、多变的行为和制造的简便性使这些材料成为当代研究的焦点。由于几纳米的低偏压传输,它们在电子设备中有着广泛的应用,而寻找它们的潜在应用则是一个复杂的过程。由于价带和导带是对称的,因此它们具有直带隙,可用于光发射。生成碳纳米管(CNT)可采用三种工艺,包括电弧放电、激光烧蚀和化学气相沉积,但化学气相沉积(CVD)是最常用的方法,因为它能生成纯度超过 98% 的 CNT。100% 纯度的 MWCNTs 的多重手性可增强光学特性,并改善其作为光收集材料的用途。利用 CNT 复合材料和功能化纳米管,可以构建染料敏化太阳能电池。本文简要讨论了 CNT 的合成及其在太阳能电池中的应用。
