This article depicts the role of the Digital Calibration Certificate (DCC) for an end-to-end digital quality infrastructure and as the basis for developments that are designated by the keyword “Industry 4.0”. Furthermore, it describes the impact the DCC has on increasing productivity in the manufacturing of products and in global trade. The DCC project is international in its scope. Calibration certificates document the measurement capability of a measurement system. They do this independently and by providing traceability to measurement standards. Therefore, they do not only play an important role in the world of metrology, but they also make it possible for manufacturing and commercial enterprises to exchange measurement values reliably and correctly at the national and at the international level. Thus, a DCC concept is urgently needed for the end-to-end digitalization of industry for the era of Industry 4.0 and for Medicine 4.0. A DCC brings about important advantages for issuers and for users. The DCC leads to the stringent, end-to-end, traceable and process-oriented organization of manufacturing and trading. Digitalization is thus a key factor in the field of calibration as it enables significant improvements in product and process quality. The reason for this is that the transmission of errors will be prevented, and consequently, costs will be saved as the time needed for distributing and disseminating the DCCs and the respective calibration objects will be reduced. Furthermore, it will no longer be necessary for the test equipment administration staff to update the data manually, which is a time-consuming, tedious and error-prone process.
本文描述了数字校准证书(DCC)在端到端数字质量基础设施中的作用,以及作为关键字“工业4.0”指定的发展基础。此外,它还描述了DCC对提高产品制造和全球贸易生产率的影响。DCC项目的范围是国际性的。校准证书记录了测量系统的测量能力。它们通过提供对测量标准的可追溯性来独立完成这项工作。因此,它们不仅在计量领域发挥着重要作用,而且还使制造和商业企业能够在国家和国际层面上可靠、正确地交换测量值。因此,在工业4.0和医学4.0时代,迫切需要一个DCC概念来实现工业的端到端数字化。DCC为发行者和用户带来了重要的优势。DCC导致严格的、端到端、可追溯和面向流程的制造和贸易组织。因此,数字化是校准领域的关键因素,因为它可以显著提高产品和过程质量。这样做的原因是可以防止误差的传播,因此可以节省成本,因为分发和传播dcs和各自校准对象所需的时间将减少。此外,测试设备管理人员将不再需要手动更新数据,这是一个耗时、繁琐且容易出错的过程。

Identity management describes a problem by providing the authorized owners with safe and simple access to information and solutions for specific identification processes. The shortcomings of the unimodal systems have been addressed by the introduction of multimodal biometric systems. The use of multimodal systems has increased the biometric system’s overall recognition rate. A new degree of fusion, known as an intelligent Dual Multimodal Biometric Authentication Scheme, is established in this study. In the proposed work, two multimodal biometric systems are developed by combining three unimodal biometric systems. ECG, sclera, and fingerprint are the unimodal systems selected for this work. The sequential model biometric system is developed using a decision-level fusion based on WOA-ANN. The parallel model biometric system is developed using a score-level fusion based on SSA-DBN. The biometric authentication performs preprocessing, feature extraction, matching, and scoring for each unimodal system. On each biometric attribute, matching scores and individual accuracy are cyphered independently. A matcher performance-based fusion procedure is demonstrated for the three biometric qualities because the matchers on these three traits produce varying values. The two-level fusion technique (score and feature) is implemented separately, and their results with the current scheme are compared to exhibit the optimum model. The suggested plan makes use of the highest TPR, FPR, and accuracy rates.
身份管理通过向授权的所有者提供对信息的安全和简单的访问以及针对特定识别过程的解决方案来描述问题。单峰系统的缺点已经通过引入多峰生物识别系统得到解决。多模式系统的使用提高了生物识别系统的整体识别率。本研究建立了一种新的融合度,称为智能双多模态生物特征认证方案。在提出的工作中,两个多模态生物识别系统是由三个单模态生物识别系统相结合而开发的。心电图、巩膜和指纹是这项工作选择的单峰系统。采用基于WOA-ANN的决策级融合方法开发了序列模型生物识别系统。采用基于SSA-DBN的分数级融合技术开发了并行模型生物识别系统。生物识别认证对每个单峰系统执行预处理、特征提取、匹配和评分。在每个生物特征属性上,匹配分数和个体准确性是独立加密的。由于这三种生物特征的匹配器产生不同的值,因此演示了基于匹配器性能的融合过程。分别实现了两级融合技术(分数和特征),并将其结果与现有方案进行了比较,得出了最优模型。建议的计划利用最高的TPR、FPR和准确率。

The goal of the work is to enhance existing financial market forecasting frameworks by including an additional factor–in this example, a collection of carefully chosen tweets—into a long-short repetitive neural channel. In order to produce attributes for such a forecast, this research used a unique attitude analysis approach that combined psychological labelling and a valence rating that represented the strength of the sentiment. Both lexicons produced extra properties such 2-level polarization, 3-level polarization, gross reactivity, as well as total valence. The emotional polarity explicitly marked into the database contrasted well with outcomes of the innovative lexicon approach. Plotting the outcomes of each of these concepts against actual market rates of the equities examined has been the concluding step in this analysis. Root Mean Square Error (RMSE), preciseness, as well as Mean Absolute Percentage Error (MAPE) were used to evaluate the results. Across most instances of market forecasting, attaching an additional factor has been proven to reduce the RMSE and increase the precision of forecasts over lengthy sequences.
这项工作的目标是通过将一个额外的因素——在这个例子中,一组精心挑选的推文——纳入一个多空重复神经通道,来增强现有的金融市场预测框架。为了产生这种预测的属性,本研究使用了一种独特的态度分析方法,将心理标签和代表情绪强度的效价评级相结合。这两个词汇都产生了额外的性质,如2级极化、3级极化、总反应性和总价。明确标记到数据库中的情感极性与创新词汇方法的结果形成鲜明对比。将这些概念的结果与所研究股票的实际市场利率进行对比,是本分析的最后一步。采用均方根误差(RMSE)、精确度和平均绝对百分比误差(MAPE)对结果进行评价。在大多数市场预测的实例中,附加一个额外的因素已被证明可以降低RMSE并提高长序列预测的精度。

Industry 4.0: Options for Human-Oriented Work Design 工业4.0:以人为本的工作设计选项
Pub Date : 2023-02-15 DOI: 10.3390/sci5010009
H. Hirsch-Kreinsen
This contribution deals with the diffusion of Industry 4.0 technologies and their consequences for work. Additionally, design options for work in Industry 4.0 are discussed. The following are outlined: First, since there are as yet no concrete future prospects for digital work, different development perspectives can be envisioned. Second, the development of Industry 4.0, therefore, has to be regarded as a design project. One theoretical basis for this is the “sociotechnical systems” approach. Third, this approach enables criteria for the design and implementation of human-oriented forms of digitized work to be systematically developed. The empirical basis of this contribution derives from research findings on the implementation of Industry 4.0 technologies and the development of digitized work in German industry. The research results are based on qualitative research methods such as company case studies and expert interviews.
这篇文章涉及工业4.0技术的传播及其对工作的影响。此外,还讨论了工业4.0中工作的设计选项。概述如下:首先,由于数字工作目前还没有具体的未来前景,因此可以设想不同的发展前景。第二,因此,工业4.0的发展必须被视为一个设计项目。其中一个理论基础是“社会技术系统”方法。第三,这种方法使设计和实施以人为本的数字化工作形式的标准得以系统地发展。这一贡献的实证基础源于对工业4.0技术实施和德国工业数字化工作发展的研究成果。研究结果基于定性研究方法,如公司案例研究和专家访谈。

Explaining Personal and Public Pro-Environmental Behaviors 解释个人和公众的环保行为
Pub Date : 2023-02-07 DOI: 10.3390/sci5010006
Philip Q. Yang, M. Wilson
A global crisis generated by human-made climate change has added urgency to the need to fully understand human pro-environmental behaviors (PEBs) that may help slow down the crisis. Factors influencing personal and public PEBs may or may not be the same. Only a few studies have empirically investigated the determinants of personal and public PEBs simultaneously, but they contain major limitations with mixed results. This study develops a conceptual model for explaining both personal and public PEBs that incorporate demographic, socioeconomic, political, and attitudinal variables, and their direct and indirect effects. Using the latest available data from the 2010 General Social Survey and structural equation modeling (SEM), we tested the determinants of both personal and public PEBs in the United States. The results reveal that environmental concerns, education, and political orientation demonstrate similar significant impacts on both personal and public PEBs, but income, gender, race, urban/rural residency, region, and party affiliation have differential effects on these behaviors. Age, cohort, and religion have no significant effect on both types of behaviors. Our results confirm some existing findings; however, they challenge the findings of much of the literature.
人为造成的气候变化引发的全球危机,使我们更加迫切需要充分了解可能有助于减缓危机的人类亲环境行为(PEBs)。影响个人和公共peb的因素可能是相同的,也可能不是相同的。只有少数研究同时对个人和公共peb的决定因素进行了实证调查,但它们存在重大局限性,结果好坏参半。本研究开发了一个概念模型来解释个人和公共PEBs,包括人口、社会经济、政治和态度变量,以及它们的直接和间接影响。利用2010年综合社会调查和结构方程模型(SEM)的最新可用数据,我们测试了美国个人和公共peb的决定因素。结果表明,环境问题、教育和政治取向对个人和公共环境行为的影响相似,但收入、性别、种族、城乡居住、地区和党派对这些行为的影响存在差异。年龄、群体和宗教对这两种行为没有显著影响。我们的研究结果证实了一些已有的发现;然而,他们对许多文献的发现提出了质疑。

Socioconnectomics: Connectomics Should Be Extended to Societies to Better Understand Evolutionary Processes 社会连接组学:连接组学应该扩展到社会,以更好地理解进化过程

Connectomics, which is the network study of connectomes or maps of the nervous system of an organism, should be applied and expanded to human and animal societies, resulting in the birth of the domain of socioconnectomics compared to neuroconnectomics. This new network study framework would open up new perspectives in evolutionary biology and add new elements to theories, such as the social and cultural brain hypotheses. Answering questions about network topology, specialization, and their connections with functionality at one level (i.e., neural or societal) may help in understanding the evolutionary trajectories of these patterns at the other level. Expanding connectomics to societies should be done in comparison and combination with multilevel network studies and the possibility of multiorganization selection processes. The study of neuroconnectomes and socioconnectomes in animals, from simpler to more advanced ones, could lead to a better understanding of social network evolution and the feedback between social complexity and brain complexity.
连接组学是对生物神经系统的连接体或图谱的网络研究,它应该被应用并扩展到人类和动物社会,从而产生了与神经连接组学相比的社会连接组学领域。这种新的网络研究框架将为进化生物学开辟新的视角,并为诸如社会和文化大脑假说等理论增添新的元素。回答有关网络拓扑、专门化及其与一个层次(即神经或社会)功能的联系的问题,可能有助于理解这些模式在另一个层次上的进化轨迹。将连接组学扩展到社会,应该与多层次网络研究和多组织选择过程的可能性进行比较和结合。对动物的神经连接体和社会连接体的研究,从简单到高级,可以更好地理解社会网络的进化,以及社会复杂性和大脑复杂性之间的反馈。

The Impact of Trap-Assisted Tunneling and Poole–Frenkel Emission on Synaptic Potentiation in an α-Fe2O3/p-Si Memristive Device 陷阱辅助隧穿和池- frenkel发射对α-Fe2O3/p-Si忆阻器件突触增强的影响

A signature of synaptic potentiation conductance has been observed in an α-Fe2O3/p-Si device fabricated using spin coating. The conductance of the device in dark conditions and illumination with a white light source was characterized as a function of the application of a periodic bias (voltage) with a triangular profile. The conductance of the device increases with the number of voltage cycles applied and plateaus to its maximum value of 0.70 μS under dark conditions and 12.00 μS under illumination, and this mimics the analog synaptic weight change with the action potential of a neuron. In the range of applied voltage from 0 V to 0.7 V, the conduction mechanism corresponds to trap-assisted tunneling (TAT) and in the range of 0.7–5 V it corresponds to the Poole–Frenkel emission (PFE). The conductance as a function of electrical pulses was fitted with a Hill function, which is a measure of cooperation in biological systems. In this case, it allows one to determine the turn-on threshold (K) of the device in terms of the number of voltage pulses, which are found to be 3 and 166 under dark and illumination conditions, respectively. The gradual conductance change and activation after a certain number of pulses perfectly mimics the synaptic potentiation of neurons. In addition, the threshold parameter extracted from the Hill equation fit, acting as the number of pulses for synaptic activation, is found to have programmability with the intensity of the light illumination.
在自旋涂层制备的α-Fe2O3/p-Si器件中观察到突触增强电导的特征。该器件在黑暗条件和白光光源照明下的电导的特征是具有三角形轮廓的周期性偏置(电压)应用的函数。该装置的电导随电压循环次数的增加而增加,在黑暗条件下达到最大值0.70 μS,在光照条件下达到最大值12.00 μS,这模拟了神经元的突触重量随动作电位的变化。在施加电压0 ~ 0.7 V范围内,传导机制对应于陷阱辅助隧穿(TAT),在0.7 ~ 5 V范围内,传导机制对应于普尔-弗伦克尔发射(PFE)。电导作为电脉冲的函数用Hill函数拟合,Hill函数是生物系统中合作的度量。在这种情况下,它允许人们根据电压脉冲的数量来确定器件的导通阈值(K),在黑暗和照明条件下分别为3和166。经过一定数量脉冲后的逐渐电导变化和激活,完美地模拟了神经元的突触增强。此外,从Hill方程中提取的阈值参数拟合,作为突触激活的脉冲数,发现与光照强度具有可编程性。

In this case, it allows one to determine the turn-on threshold (K) of the device in terms of the number of voltage pulses, which are found to be 3 and 166 under dark and illumination conditions, respectively. The gradual conductance change and activation after a certain number of pulses perfectly mimics the synaptic potentiation of neurons. In addition, the threshold parameter extracted from the Hill equation fit, acting as the number of pulses for synaptic activation, is found to have programmability with the intensity of the light illumination.","PeriodicalId":10987,"journal":{"name":"Decis.

With the increasing interest in the identification of differences between camel breeds over the last decade, this study was conducted to estimate the variability of milk production and composition of four Saudi camel breeds during different seasons. Milk records were taken two days per week from females of Majahem, Safra, Wadha, and Hamra breeds distributed over Saudi Arabia. The milk yield during winter indicated that the weekly average of the Wadha breed was significantly lower (27.13 kg/week) than Majahem and Hamra breeds. The Safra breed had the lowest milk yield (30.7 kg/week) during summer. During winter, the Hamra breed had a lower content of all analyzed milk components except proteins and was characterized by a lower pH than the milk of the other breeds. However, the Hamra breed had significantly higher contents of milk fat and lactose than the other breeds during summer, with the corresponding values of 3.87 and 4.86%, respectively. Milk collected during winter from Majahem, Safra, and Wadha breeds was characterized by a significant increase in all milk components and milk pH. Finally, the isoelectric focusing analysis revealed noticeable variability of casein purified from camel milk within the different Saudi breeds, with the highest significant value of 2.29 g per 100 mL recorded for the Wadha breed.
在过去的十年中,随着人们对骆驼品种之间差异的兴趣日益浓厚,本研究旨在估计四个沙特骆驼品种在不同季节的产奶量和组成的变异性。每周两天对分布在沙特阿拉伯的Majahem、Safra、Wadha和Hamra品种的雌性进行乳汁记录。冬季产奶量表明,Wadha品种的周平均产奶量(27.13 kg/周)显著低于Majahem和Hamra品种。Safra品种夏季产奶量最低(30.7 kg/周)。在冬季,哈姆拉品种除蛋白质外,所有分析的奶成分含量都低于其他品种,其特点是pH值低于其他品种。Hamra品种夏季乳脂和乳糖含量显著高于其他品种,分别为3.87和4.86%。在冬季采集的Majahem、Safra和Wadha品种的奶中,所有奶成分和奶ph值都显著增加。最后,等电聚焦分析显示,从不同沙特品种的骆驼奶中纯化的酪蛋白存在显著差异,Wadha品种的酪蛋白含量最高,为2.29 g / 100 mL。
