Due to the strong evaporation and leakage loss, secondary saline-alkali was the main problem in the watershed of gully land consolidation on Loess Plateau. Through field farming experiments, five modifiers (maize stalk (MS), humus acid (HA), Yan Ke (YK), He Kang (HK), and nanobiochar (NB)) were studied to investigate the effects of these soil modifiers on soil water and salt distribution, leaf photosynthetic characteristics, and maize growth and yields, as well as economic benefits in secondary saline-alkali soils of gully land consolidation watershed on Loess Plateau in 2019 and 2020. The results showed that soil modifiers could increase the water-holding capacity of the soil, reduce the salt content of the soil profiles, and decompose the accumulation of salt. The maximum desalination rate obtained in 2019 and 2020 increased, respectively, by 71.57% and 46.02%, compared to that in the control treatment. Soil modifiers could increase the net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), and decreased the intercellular CO2 concentration (Ci). The output increased by 13.63%-31.84%, and revenue increased by 6.48%-38.01%. According to analyzing the production of soil modifier application, we found that the highest net profit was achieved when HK application rate was 52.4 kg/ha. Therefore, this study suggested that 52.4 kg/ha might be recommended as an appropriate soil modifier application strategy to deal with crop growth and improve economic benefit in secondary saline-alkali soils of Northwest China.
黄土高原沟壑区土地整治的主要问题是次生盐碱,由于其蒸发和渗漏损失较大。通过田间耕作试验,研究了5种土壤改良剂(玉米秸秆(MS)、腐殖酸(HA)、烟碱(YK)、贺康(HK)和纳米生物炭(NB))在2019年和2020年对黄土高原沟壑区土地整治小流域次生盐碱土土壤水盐分布、叶片光合特性、玉米生长和产量及经济效益的影响。结果表明,土壤改良剂能提高土壤的持水能力,降低土壤剖面的含盐量,分解盐分的积累。与对照处理相比,2019年和2020年的最大脱盐率分别提高了71.57%和46.02%。土壤改化剂可以提高净光合速率(Pn)、蒸腾速率(Tr)和气孔导度(Gs),降低细胞间CO2浓度(Ci)。产量增长13.63% ~ 31.84%,收入增长6.48% ~ 38.01%。通过对土壤改良剂施用产量的分析发现,当HK施用量为52.4 kg/ha时,净利最高。因此,建议施用52.4 kg/ha为改善西北次生盐碱地作物生长和提高经济效益的适宜土壤改良剂施用策略。

To solve the problem of unclear entity boundaries and low recognition accuracy in Chinese text, we construct the crop dataset and propose a Bert-binary-based entity link method. Candidate entity sets are generated through entity matching in multiple data sources. The Bert-binary model is called to calculate the correct probability of the candidate entity, and the entity with the highest score is screened for linking. In comparative experiments with three models on the crop dataset, the F 1 value is increased by 2.5% on the best method or by 8.8% on average. The experimental results show the effectiveness of Bert-binary method in this paper.

5G wireless networks are attracting attention due to their high data rates and robustness to multimedia options. Based on 5G wireless multimedia technology, this paper constructs an auxiliary marketing strategy for multipath collaboration. Based on the 5G wireless network system, the model solves the optimization problem of effective service energy consumption. The solution of the problem is obtained through a two-step solution and related algorithms, and the numerical simulation proves that the multipath cooperative transmission strategy has the advantages of network delay and effective service performance. In the simulation process, a 5G NR downlink system simulation model is established according to the wireless data transmission theory; in the marketing strategy estimation, the decision feedback marketing strategy estimation algorithm is improved to improve the marketing strategy estimation performance, which can effectively reduce insertion loss of the network. The results show that with the increase of the marketing data center density, the receiving delay decreases and the energy efficiency increases; when the number of video contents in the marketing data center is configured as 264, the effective service performance under the single-path transmission strategy can be achieved. Compared with the minimum value of the effective service energy consumption under the single-path transmission strategy, the minimum value of the effective service energy consumption under the multipath cooperative transmission strategy is reduced by 11.5%, which effectively improves the network throughput of data.

Building microrenovation refers to the building renewal method implemented through partial demolition, repair, preservation, function replacement, renovation, improvement, protection, decoration, and activation under the premise of maintaining the current construction pattern basically unchanged. City information modeling (CIM) technology provides a three-dimensional space floor with all elements for refined city governance and smart city construction; the data layers of smart sensor network (SSN) technology can aggregate multisource data by docking with facility layers and can classify integrated data resources. On the basis of summarizing and analyzing the previous research results, this study expounded the research status and significance of data analysis of building microrenovation, elaborated the development background, current status, and future outlooks of CIM and SSN, introduced the methods and principles of the aggregation and segmentation of information resources and the aggregation and interconnection of multisource data, performed the feature extraction and data storage of the original buildings, conducted the scheme design and information classification of microrenovation, implemented the data extraction and model construction of building microrenovation based on CIM and SSN, performed the data analysis of building appearance improvement, conducted the data analysis of building function replacement, implemented the database establishment and data analysis of building microrenovation based on CIM and SSN, and finally carried out a case application and its result analysis by taking a middle school two-story teaching building as an example. The study results show that the CIM technology can provide buildings’ actual data information such as geometry, physics, structure, and rules for building microrenovation; the SSN technology greatly reduces a lot of work caused by the rewiring of control system in the construction of building microrenovation. The combination of CIM and SSN can effectively connect various entity elements in building microrenovation to form a theme library through various data spatial relationships and spatial coding, realizing the connection of spatial data and nonspatial data in multiple dimensions. The data analysis of building microrenovation based on CIM and SSN includes multiple dimensions of achievements, processes, resources, characteristics, and applications, which is more in line with CIM integration applications and is easier for realistic information exchange and sharing applications.

The sensor units are considered one of the significant technologies that use solar energy as an assistant power source to the batteries. Despite their advantages over the other forms of renewables, solar energy has an intermittent nature which negatively affects the operation of these units. Reaching an effective operation ensuring sustainable units requires a prior prediction of the harvested solar energy. Artificial neural networks (ANNs) appeared recently as a promising prediction approach with those units. This is attributed to the high accuracy compared to the conventional stochastic and statistical ones. Till now, the optimal neural network that fits with sensor units has not been precisely determined. This paper is aimed at finding the optimal neural network that would be applied with solar-supplied sensor units. This is performed by applying a cascaded input/structure direct optimization. The optimization process handles the aspects of accuracy, computational efforts, and complexity. It mainly identifies the type and number of parameters that would be utilized as inputs in the first stage. Then, it optimizes the structure by addressing the number of hidden layers and hidden neurons. The corresponding analysis has been implemented for premeasured real data over five-year time period. The results showed that the optimal neural network can be achieved by using three input parameters which are the air temperature (AT), the relative humidity (RH), and the zenith angle ( θ z ). For the structure, it has been concluded that the proposed optimal ANN should have two hidden layers with ten neurons in each of them. Lastly, the proposed optimal ANN was verified against the associated prediction error which is minimized to less than 2%.
传感器单元被认为是利用太阳能作为电池辅助电源的重要技术之一。尽管与其他形式的可再生能源相比,太阳能具有优势,但它具有间歇性,这对这些装置的运行产生了负面影响。达到有效的操作,确保可持续的单位需要预先预测所收集的太阳能。人工神经网络(ANNs)最近作为一种很有前途的预测方法出现在这些单元中。这是由于与传统的随机和统计方法相比,该方法具有较高的准确性。到目前为止,适合传感器单元的最优神经网络还没有得到精确的确定。本文的目的是寻找应用于太阳能传感器单元的最优神经网络。这是通过应用级联输入/结构直接优化来实现的。优化过程处理精度、计算量和复杂性方面的问题。它主要确定将在第一阶段用作输入的参数的类型和数量。然后,通过寻址隐藏层和隐藏神经元的数量来优化结构。对5年期间的预测实际数据进行了相应的分析。结果表明,采用空气温度(AT)、相对湿度(RH)和天顶角(θ z) 3个输入参数可获得最优神经网络。对于这种结构,我们认为最优的人工神经网络应该有两个隐含层,每个隐含层有10个神经元。最后,对所提出的最优人工神经网络进行了验证,将相关预测误差降至2%以下。

Pub Date : 2022-08-22 DOI: 10.1155/2022/8485428
Jiahuan Lin, Shantian Wen
Attendance information is an important data resource for physical education management in colleges and universities. Based on wireless and passive RFID technology theory, this paper designs a UHF passive RFID radio frequency identification physical education attendance model. The device includes three parts: carrier leakage canceller, radio frequency transceiver, and digital baseband signal processing. In the model hierarchy, the client sends a Web request to the server, and the request information is organized by the RFID document, including information such as the range, scale, and display attributes of the requested map. The Web server modifies the predefined map definition file by parsing the information. In the simulation process, the frequency domain model and baseband complex envelope time domain system of the RF front-end of the reader based on carrier leakage cancellation were built in ADS software and Matlab/Simulink, respectively. The reader front-end and digital baseband signal processing are comprehensively simulated, and the result verifies the function of the whole system. After testing and debugging, it has been proven that the median synchronization number of the signal is 12, the point synchronization number is 29, the input IDB compression point measured by a single tone is 9.6 dB smaller than that of IIP3, and the input IDB compression point measured by two tones is smaller than 14.4 dB, which can promote the informatization process of physical education management in colleges and universities.
考勤信息是高校体育教学管理的重要数据资源。基于无线和无源RFID技术理论,设计了一种超高频无源RFID射频识别体育考勤模型。该装置包括三部分:载波泄漏消除器、射频收发器和数字基带信号处理。在模型层次结构中,客户机向服务器发送Web请求,请求信息由RFID文档组织,包括所请求地图的范围、比例和显示属性等信息。Web服务器通过解析信息来修改预定义的映射定义文件。在仿真过程中,分别在ADS软件和Matlab/Simulink中构建了基于载波泄漏抵消的读写器射频前端频域模型和基带复包络时域系统。对读卡器前端和数字基带信号处理进行了全面仿真,结果验证了整个系统的功能。经过测试调试,证明该信号的中位数同步数为12,点同步数为29,单音测得的输入IDB压缩点比IIP3小9.6 dB,双音测得的输入IDB压缩点小于14.4 dB,可促进高校体育管理的信息化进程。

Intelligent sensor technology is a professional course of communication, electronics, information, computer, and other related majors and is a course of expansion and extension of computer network (Ministry of Education of the People’s Republic of China, 2001). It is connected with the Internet by using information sensing device to realize the intercommunication of time and space, people, machines, and things. Intelligent sensor technology is an advanced subject; it contains a lot of ideological elements; in teaching, it should be according to the characteristics of the subject, set the goal of ideological education, to design the content of the ideological education, improve the ideological education, to carry on the course of the construction of the ideological practice and exploration, and guide students to set up the correct world outlook, the outlook on life, and values (The State Council of the Central Committee of the Communist Party of China, 2010). Integrating the elements of thinking and politics into the teaching of intelligent sensor technology and organically combining thinking and politics teaching with professional teaching is conducive to realizing the nurturing function of professional teaching and establishing an all-round curriculum system, so that professional and thinking and politics courses can go hand in hand and produce synergy. With the concept of “civic education as the soul, general education as the root, professional education as the foundation,” the strategy of integrating civic education from “point to surface (Wei, 2015), from history to the present, from inside to outside” is summarized, and a system of assessment, evaluation, and continuous improvement is established. It also establishes a system of assessment, evaluation, and continuous improvement. The strategy has proved to be effective in combining ideological and political education with moral education, enabling students to develop theoretical, institutional, and cultural confidence on the road to socialism with Chinese characteristics (Ministry of Education of the People’s Republic of China, 2004).
智能传感器技术是通信、电子、信息、计算机等相关专业的专业课,是计算机网络的拓展和延伸课程(中华人民共和国教育部,2001)。它通过信息传感装置与互联网连接,实现时空、人、机、物的互通。智能传感器技术是一门高级学科;它包含了很多思想因素;在教学中,要根据本学科的特点,确立思想政治教育的目标,设计思想政治教育的内容,完善思想政治教育,进行思想政治建设课程的实践与探索,引导学生树立正确的世界观、人生观、价值观(中共中央国务院,2010)。将思政要素融入智能传感器技术教学中,将思政教学与专业教学有机结合,有利于实现专业教学的育人功能,建立全方位的课程体系,使专业与思政课程齐头并进,产生协同效应。以“公民教育为魂,通识教育为根,专业教育为基”的理念,总结出公民教育从“点到面(Wei, 2015),从历史到现在,从内到外”的整合策略,建立起考核、评价、持续改进的体系。它还建立了一个评估、评价和持续改进的系统。实践证明,这一战略有效地将思想政治教育与道德教育相结合,使学生在中国特色社会主义道路上树立理论自信、制度自信和文化自信(中华人民共和国教育部,2004)。

In recent years, communication technology has improved exponentially, partly owing to the locations and nature of the deployment of sensor nodes. Wireless sensor networks (WSNs) comprise these sensor nodes and can provide real-time physical and environmental measurements. The sensor nodes have limited power, which reduces their lifespan, especially when placed in human-inaccessible locations. This paper reviews energy-efficient protocols for environmental monitoring applications and energy harvesting-wireless sensor networks. The dynamic deployment and communication challenges associated with environmental monitoring applications (EMAs) make this paper take into account the WSN protocol stack, focusing on the physical layer, network layer (routing), and medium access control (MAC). The paper will delve deeper into the security challenges of deploying sensor nodes for environmental monitoring applications (EMAs). The paper further describes scientific approaches that churn out innovative and engineering applications that must be followed to improve environmental monitoring applications.
近年来,通信技术呈指数级发展,部分原因是传感器节点部署的位置和性质。无线传感器网络(wsn)由这些传感器节点组成,可以提供实时的物理和环境测量。传感器节点的功率有限,这缩短了它们的使用寿命,特别是当它们被放置在人类无法接近的位置时。本文综述了环境监测应用和能量采集无线传感器网络的节能协议。环境监测应用(ema)的动态部署和通信挑战使得本文考虑了WSN协议栈,重点关注物理层,网络层(路由)和介质访问控制(MAC)。本文将深入探讨为环境监测应用(ema)部署传感器节点的安全挑战。本文进一步描述了产生创新和工程应用的科学方法,必须遵循这些方法来改进环境监测应用。
