We propose using the irregular loading fatigue testing to study the crucial topics of the subject, for instance, concerning the fatigue limit. This characteristic is important to know (1) for test accelerating; (2) To guarantee stable, reliable service. Comparative studies under block and random loading present an opportunity to draw conclusions without the ultra-sound frequencies loading, which are at some extend controversial. We present an example of proposed method application. The second stage of fatigue – namely, the crack propagation stage, is also considered (in reference). There the main idea is similar – the irregular testing provides an opportunity to judge about the maxim among the small amplitudes, which are not harmful. Direct experimental estimation of true fatigue limit requires the testing under ultra-sound frequencies, which is not under the questions nowadays.
我们建议使用非规则载荷疲劳试验来研究该学科的关键问题,例如疲劳极限。了解这一特性是很重要的(1)对于试验加速;(2)保证稳定、可靠的服务。在块加载和随机加载下的比较研究提供了一个机会,可以在没有超声频率加载的情况下得出结论,这在一定程度上是有争议的。最后给出了该方法的应用实例。还考虑了疲劳的第二阶段,即裂纹扩展阶段(参考文献)。这里的主要思想是相似的——不规则测试提供了一个机会来判断小振幅之间的最大值,这是无害的。真实疲劳极限的直接试验估计需要在超声频下进行试验,这在目前的研究中是不存在的。

This article summarizes some of the results of our work in terms of considering various issues of reliability of mining machines – mining excavators. In this case, we are talking about the development of the basis, structure and elements of a system for express diagnostics (analysis) of these machines under operating conditions, which should be adjusted for the conditions and capabilities of engineers operating these machines to maintain their state within the framework of homeostasis (in the future, and control their state). In addition, the article presents a scheme that allows describing in an enlarged manner the entire life cycle of a mining machine, taking into account both design and operation. Additionally, there is a list of tasks that the authors plan to solve in the future.

Study of Decision-making Issues in Social Groups Based on Modelling of Incomplete Consensus 基于不完全共识模型的社会群体决策问题研究
Pub Date : 2022-03-29 DOI: 10.13052/jgeu0975-1416.1015

In many social groups, for example, in European eco-settlements, social movements (occupy), international organizations (WTO, OSCE, IPCC, etc.), decision-making is based on the consensus of the group members. Instead of voting, when the majority wins over the minority, consensus allows finding a solution that each member of the group supports or, at least, considers acceptable. This approach ensures that all the opinions of the group members, their ideas and needs will be taken into account. At the same time, reaching a consensus requires considerable time, since it is necessary to come to an agreement within the group, regardless of its size. It was shown that in some situations the number of iterations (agreements, negotiations) is very significant. Moreover, in the decision-making process, there is always a risk of blocking a decision by a minority in the group, which not only prolongs the decision-making time but even makes it impossible. As a rule, such a minority is presented by one or two odious people. Such a member of the group tries to dominate the discussion, always stands by his/her opinion, ignoring the position of the others. This leads to a protraction in the decision-making process, on the one hand, and a deterioration in the quality of consensus, on the other, since only the opinion of the dominant part of the group would be taken into account.In order to overcome this problem, it was proposed to make a decision based on the principle of “Consensus Minus One” or “Consensus Minus Two”, that is, not to take into account the opinion of one or two odious members of the group. For example, in climate researches, where many scientific disciplines are involved, a complete consensus is almost impossible. Based on the simulation of consensus using the Markov chain model, the article studies the question of how much the decision-making time is reduced when using the “Consensus Minus One” and “Consensus Minus Two” rules, if the position of the dominant members of the group is not taken into account. As it appears from the findings obtained, this paper can be in general summarized by saying that the rule of thumb applied for making a decision pursuant to the incomplete consensus principle has a solid mathematical background. The simulation results showed that its use can reduce the time required to reach a consensus to 97%, which is crucial for practice. The average number of agreements hyperbolically depends on the average authoritarianism of the group members (excluding the autocratic members), which means that the negotiation process can be protracted at high values of the above-mentioned average authoritarianism.
在许多社会群体中,例如欧洲的生态住区、社会运动(占领)、国际组织(WTO、OSCE、IPCC等),决策都是基于群体成员的共识。而不是投票,当多数战胜少数时,共识允许找到一个解决方案,每个成员都支持,或者至少是认为可以接受的。这种方法确保了小组成员的所有意见,他们的想法和需求都会被考虑在内。与此同时,达成一致意见需要相当长的时间,因为必须在集团内部达成协议,无论其规模大小。结果表明,在某些情况下,迭代(协议、协商)的数量非常重要。此外,在决策过程中,总是存在被群体中的少数人阻止决策的风险,这不仅延长了决策时间,甚至使决策无法进行。一般来说,这样的少数派是由一两个可恶的人来代表的。这样的群体成员试图主导讨论,总是坚持自己的观点,忽视其他人的立场。这一方面导致决策过程的拖延,另一方面导致协商一致意见的质量下降,因为只会考虑到集团中占主导地位的部分的意见。为了克服这一问题,有人建议根据“共识减一”或“共识减二”的原则作出决定,即不考虑群体中一两个令人讨厌的成员的意见。例如,在涉及许多科学学科的气候研究中,几乎不可能达成完全的共识。本文在利用马尔可夫链模型模拟共识的基础上,研究了在不考虑群体中优势成员地位的情况下,使用“共识减一”和“共识减二”规则时,决策时间减少了多少的问题。从所获得的研究结果来看,本文可以概括地说,根据不完全共识原则做出决策的经验法则具有坚实的数学背景。仿真结果表明,该方法的使用可将达成共识所需的时间缩短至97%,这对实践具有重要意义。协议的平均数量夸张地取决于集团成员的平均威权主义(不包括专制成员),这意味着在上述平均威权主义的高值时,谈判过程可能会延长。

With every up-gradation made in the software there are chances that the number of new faults might creep in the software. This concept has been readily worked upon in the past and is still an active area of research. Software industry has been readily evolving with time and has seen many advancements wherein innovation rate and creation of knowledge has played a pivotal role for continued growth of firms. Often, the use of coming up with new set of features in the base product has brought in answers to many user’s queries. But these up-gradations also known as add-ons also bring in certain new flaws in the software system which is newly created. In the current paper, this fundamental has been worked upon with the help of certain proposed models. Results are supplemented with numerical examples.
随着软件的每一次升级,软件中都有可能出现新的故障。这个概念在过去已经很容易地工作,并且仍然是一个活跃的研究领域。软件行业已经随着时间的推移而不断发展,并且已经看到了许多进步,其中创新率和知识的创造对公司的持续增长起着关键作用。通常,在基础产品中提出一组新特性的使用会为许多用户的查询带来答案。但是,这些升级也被称为附加组件,也会给新创建的软件系统带来一些新的缺陷。在当前的论文中,这一基本原理已经在某些拟议模型的帮助下进行了研究。结果辅以数值算例。

Corona Virus has spread across the globe and is creating havoc. Lockdown is being imposed worldwide depending on the number of cases. Everyone are advised to wear masks, follow social distancing, and use hand sanitizers to keep them safe. But all these precautions are not enough to curb the spread of the disease. People are still getting infected even after taking proper precautions and obeying the lockdown rule. We need to know in advance the approximate number of infected people so that we can devise better precautionary measures to curb the spread of the virus. So we use a simple SIR Model and solve it using basic differentiation and integration techniques and then use recurrence formula approach to predict the spread of COVID-19 in the city of Sambalpur of Odisha state. We compare the outcome of the model with the real time data and we arrive at the conclusion that the model is efficient in predicting the spread using the recurrence formula till the date 05/06/2021.
冠状病毒已在全球蔓延,并正在造成严重破坏。根据病例数量,全球范围内正在实施封锁。建议每个人都戴口罩,保持社交距离,并使用洗手液来保证自己的安全。但所有这些预防措施都不足以遏制这种疾病的传播。即使采取了适当的预防措施并遵守了封锁规定,仍然有人被感染。我们需要事先知道受感染人数的大致数字,以便我们能够制定更好的预防措施,遏制病毒的传播。因此,我们使用一个简单的SIR模型,并使用基本的微分和积分技术对其进行求解,然后使用递归公式方法预测2019冠状病毒病在奥里萨邦桑巴尔普尔市的传播。我们将模型的结果与实时数据进行比较,得出的结论是,该模型可以有效地使用递归公式预测到2021年6月5日的价差。

Nano silica (SiO2) has an extensive range of products from manufacturing to scientific. The Sol-gel technique in the field of material science is receiving worldwide interest because of its versatility for synthesizing silica nanoparticles. It provides a controlled composition of organic/inorganic hybrid material because of its unique and low-cost processing. The silica nanoparticles were prepared by the sol-gel method via two different routes first is a base-catalyzed hydrolysis reaction and the second is an acid-catalyzed hydrolysis reaction. The prepared silica nanoparticles were characterized by techniques Particle size analysis, Zeta potential, Fourier transform Infrared spectroscopy (FTIR), and X-Ray diffraction spectroscopy (XRD). Particle size analysis showed the nano range of particle and zeta potential proves the stability of prepared sols. Observed peaks from IR spectra are confirming the presence of a silica network. The amorphous silica was verified by the absence of sharp peaks and the presence of a broad peak at a 2θ angle of 23.8 for the XRD analysis structure in the produced NPs.
纳米二氧化硅(SiO2)具有广泛的产品范围,从制造到科学。溶胶-凝胶技术在材料科学领域因其合成二氧化硅纳米颗粒的多功能性而受到全世界的关注。由于其独特和低成本的加工,它提供了有机/无机杂化材料的可控组成。采用溶胶-凝胶法制备二氧化硅纳米颗粒,制备途径有碱催化水解反应和酸催化水解反应两种。采用粒度分析、Zeta电位、傅里叶红外光谱(FTIR)和x射线衍射光谱(XRD)等技术对制备的二氧化硅纳米颗粒进行了表征。粒径分析表明,所制备的溶胶具有纳米级的粒径范围和zeta电位,证明了所制备溶胶的稳定性。观察到的红外光谱峰证实了二氧化硅网络的存在。制备的NPs中没有尖锐的峰,在2θ角23.8处有一个宽峰,证实了非晶态二氧化硅的存在。

COVID-19 had far-reaching consequences for different economic sectors around the world. While the impact was not standardised throughout, one thing was consistent: every sector and region, including India and the Indian insurance sector, faced challenges in adapting to the new normal. The insurance industry provided both life and non-life or general insurance. COVID-19 had a mixed effect on the insurance industry. The effect of COVID-19 on the insurance industry was not uniform; some products saw a significant increase in business, while others saw a significant decrease. The aim of this research is to examine and assess the overall effect of COVID-19 on the insurance industry with emphasis on the steps to be taken to prepare the insurance sector to deal with these types of the consequences in the future. Data from the regulatory authority’s website is used to compile and analyse the findings of the study.
2019冠状病毒病对全球不同经济部门产生了深远影响。尽管其影响并不是统一的,但有一点是一致的:每个行业和地区,包括印度和印度保险业,都面临着适应新常态的挑战。保险业既提供人寿保险,也提供非人寿保险或一般保险。新冠肺炎疫情对保险业的影响好坏参半。新冠肺炎疫情对保险业的影响并不均匀;一些产品的销量显著增长,而另一些产品的销量则显著下降。本研究的目的是检查和评估COVID-19对保险业的总体影响,重点是为保险业在未来应对这些类型的后果而准备采取的步骤。来自监管机构网站的数据用于汇编和分析研究结果。

This paper aims to investigate the relationship between the multipath phase of Global Navigation Satellite System (GNSS) and volumetric moisture content (VMC) of soil. The carrier to noise ratio (C/No) data of multipath signals at two different frequencies has been analyzed. The first one is India’s NavIC L5 frequency (∼1176 MHz) and the second one is GPS L1 frequency (∼1575 MHz). The received multipath signals are highly dependent on dielectric value of soil and the elevation angle of satellite. The relationship drawn for the NavIC and GPS C/No data is based on multipath phase analysis and in situ soil moisture. The values of correlation coefficient observed between these parameters were 0.9 and 0.63 for NavIC and GPS multipath signal respectively. The result from both GNSS shows good sensitivity and could be used to estimate the soil moisture for agricultural land.
本文旨在研究全球卫星导航系统(GNSS)多径相位与土壤体积含水量(VMC)之间的关系。分析了两种不同频率下多径信号的载波噪声比(C/No)数据。第一个是印度的NavIC L5频率(~ 1176 MHz),第二个是GPS L1频率(~ 1575 MHz)。接收到的多径信号高度依赖于土壤的介电值和卫星的仰角。NavIC和GPS C/No数据的关系是基于多径相位分析和原位土壤湿度。NavIC和GPS多径信号的相关系数分别为0.9和0.63。两种GNSS的结果均具有良好的灵敏度,可用于估算农田土壤湿度。

In spite of the fact that previous researchers have utilized different systems of moisture content assurance of soils. In this specific situation, analysts have built up a few systems for estimating the soil moisture eg., thermo gravimetric, neutron dissipating, soil resistivity, dielectric methods and Radar Remote Sensing method using SAR (Synthetic-aperture radar) images. Be that as it may, these methods are very mind boggling, costly (because of very intricate hardware and gear) and henceforth past the span of many. This audit accentuates that why it winds up basic to assess different techniques utilized by the analysts for assurance of the soil moisture. Likewise, a necessity for finding new soil moisture estimation methods or altering the current strategies has been surveyed.
尽管以前的研究人员使用了不同的土壤含水量保证系统。在这种特殊情况下,分析人员已经建立了一些系统来估计土壤湿度。热重法、中子耗散法、土壤电阻率法、介电法和雷达遥感法。尽管如此,这些方法是非常令人难以置信的,昂贵的(因为非常复杂的硬件和齿轮),并且从此以后超出了许多人的跨度。这次审计强调了为什么它是基本的评估不同的技术使用的分析,以确保土壤湿度。同样,寻找新的土壤水分估算方法或改变现有策略的必要性也得到了调查。
