Design and Implementation of 10kV Distribution Network Distribution Dispatching System Based on Eclipse Development Platform

In order to meet people's requirements for power quality and distribution network reliability, a distribution dispatching system for urban distribution network based on Eclipse as the development platform, Oracle as the database and eOMP as the software support is developed. After the demand analysis of the distribution network, the functional structure of the system is determined, and the overall design and detailed design of the system are carried out. The rule base is constructed according to the operation rules of distribution lines, and the knowledge base of operation order expert system is represented and inferred by BP (Back Propagation) neural network model. The results show that the system runs reliably and smoothly. Through this system, the power grid company can compile and implement the normal operation mode of distribution network, draw a primary wiring diagram of the line, make maintenance plan, and carry out scheduling and operation management of relay protection and automation devices in distribution network. Thus, the system helps to improve the power supply capacity and reliability of distribution network and reduce its operation cost.

Neural Network-Based Mapping Mining of Image Style Transfer in Big Data Systems.

Image style transfer can realize the mutual transfer between different styles of images and is an essential application for big data systems. The use of neural network-based image data mining technology can effectively mine the useful information in the image and improve the utilization rate of information. However, when using the deep learning method to transform the image style, the content information is often lost. To address this problem, this paper introduces L1 loss on the basis of the VGG-19 network to reduce the difference between image style and content and adds perceptual loss to calculate the semantic information of the feature map to improve the model's perceptual ability. Experiments show that the proposal in this paper improves the ability of style transfer, while maintaining image content information. The stylization of the improved model can better meet people's requirements for stylization, and the evaluation indexes of structural similarity, cosine similarity, and mutual information value have increased by 0.323%, 0.094%, and 3.591%, respectively.

Application and research of nano-biomaterials in the rehabilitation of sports tendon rupture

Nano-biomaterials have important application and development in the field of tendon fracture rehabilitation. However, with the continuous improvement of people's requirements for tendon repair, the traditional single biomaterials are difficult to meet the actual needs of tendon repair, so the biomaterials have gradually developed. Biocomposites often have the comprehensive advantages of two or more materials, which can achieve optimal and purposeful tissue repair. In this paper, the effects of nanocomposites with dual functions of tendon regeneration and barrier on the rehabilitation of exercise-induced tendon rupture will be studied. In this paper, nanowire/polylactic acid double-sided synthetic materials are mainly used in the actual preparation of biomaterials. Its main purpose is to overcome the contradiction between tendon-induced suture and adhesion of surrounding tissues in the process of tendon repair of traditional biomaterials. In the experimental part of this paper, based on the tendon rupture of a patient, the Achilles tendon suture experiment was carried out with the mixed biomaterials proposed in this paper. The experiment shows that the comprehensive biomaterials proposed in this paper have obvious rehabilitation advantages.

Practical Exploration of Effective English Grammar Teaching in Senior High Schools from the Perspective of Cognitive Linguistics

With the continuous construction and development of our society, people's requirements for English teaching in senior high schools have gradually increased. Teachers are required to guide students based on their better application of English, instead of letting students master simple vocabulary and grammar, so that every student can become a high-quality talent who can communicate freely in English, instead of a dumb English talent. Therefore, in the process of classroom teaching, English teachers in senior high schools must attach importance to the reform of English teaching, and be able to effectively guide students in more advanced ways. Based on cognitive linguistics, this paper briefly expounds the connotation and key points of English teaching in senior high schools, and then puts forward some strategies for the reform of English teaching in senior high schools, hoping to inspire teachers and colleagues.

Situational Perception Information Fusion Technology of Internet of Things for Smart Library

Impacts of changing urban land-use structure on sustainable city growth in China: A population-density dynamics perspective

The dynamics of urban population density (UPD) has attracted extensive attention from both policymakers and scholars because it can be used to indicate the sustainability of city growth. Substantial research considering urban areas as whole units has demonstrated a close relationship between urban land expansion and demographic urbanization. However, the impacts of the urban land-use structure (ULUS) on sustainable city growth from the perspective of UPD dynamics have largely been ignored. Based on the understanding of human–land interactions in the process of city evolution, we present a holistic theoretical framework for the impacts of changing ULUS on UPD dynamics. Taking 331 cities proper in China as the study objects, we found that the designation of urban land has mostly depended upon land substitution resulting from the high economic returns of land used for secondary and tertiary industries and residential purposes. This is induced by the increasing scarcity of urban land and people's primary requirements for the dwelling and employment functions of a city rather than its living-environment function. The results confirmed that the holistic theoretical framework is effective for understanding the impacts of changing ULUS on UPD dynamics, and that taking consideration of these impacts in the structural reform of urban land supply is significant for promoting sustainable city growth. This study also provides inspiration for understanding the uncertainties relating to sustainable city growth based on identification of city shrinkage and growth patterns. We discuss regionally differentiated policies relating to structural reform of urban land supply and strategies for coping with city shrinkage.

QoE-Aware 3D Video Streaming via Deep Reinforcement Learning in Software Defined Networking Enabled Mobile Edge Computing

With the advancements of wireless network transmission technology, 2D video is hard to satisfy people's requirement for multimedia. Therefore, the high-definition 3D video that can bring a whole new viewing experience is starting to enter people's vision. However, when a tremendously large number of users play 3D video, it puts enormous computational pressure on the cloud server, which incurs high transmission latency. To release the tension, in this articl we consider a promising computing and networking architecture by incorporating Mobile Edge Computing (MEC) and Software-defined Networking (SDN) and propose a novel resource allocation model (RAM) to allocate resources and reduce delay. At the same time, we introduce the Quality of Experience (QoE) Model (QoEM), which uses information collected during 3D video playback to adaptively allocate the rate of future tiles. The model addresses the problem of assigning the best transmission speed to the block in the case of time-varying characteristicfactors during transmission. We propose an Actor-Critic-based deep reinforcement learning algorithm for viewport prediction and QoE optimization, called QoE-AC. For the differential transmission in the playback phase, we use the LSTM network for bandwidth and viewport prediction, while combining the historical information of the blocks into the Actor-Critic network as observations. The network can be adaptively assigned the best transmission speed for future tiles based on observations to maximize QoE. Finally, the experimental results show that the actual performance of the model is much better than other existing 3D video network models. Under different QoE targets, our proposed system can be adapted to all situations and has a 10%-15% performance improvement.

(eds.), Sustainable Development in Coastal Regions: A Perspective of Environment, Economy, and Technology. Journal of Coastal Research, Special Issue No. 112, pp. 106-108. Coconut Creek (Florida), ISSN 0749-0208.With the development of social economy and the improvement of people's living standards, people's consumption requirements have changed from the initial emphasis on products and services to the emphasis on experience. The 21st century is an era of experience economy and ocean, which gives new opportunities and challenges to marine tourism. Sports industry has become one of the most promising industries in the 21st century. “Experience” and “tourism +, sports +” have gradually become the new choice of people's lifestyle. At present, most of the sports tourism products in coastal cities of China are in the primary stage of meeting the basic spiritual needs of customers, which is mainly a single structure product of coastal tourism. Based on the consumption demand in the era of experience economy, this paper puts forward the change of leisure consumption demand and marketing innovation mode, which requires us to continuously develop marine sports tourism products. Based on the customer satisfaction model of experience consumption, this paper analyzes the development of marine sports tourism. This paper constructs the SWOT model, which can better analyze the development of marine tourism. Finally, some suggestions are put forward.

The concept of minimally invasive first aid and its position in emergency treatment of critical illness

With the development of society and economy, people's requirements for emergency rescue technology and emergency services are gradually increasing. Building and improving the emergency of critical care system is an important issue currently facing. Controlling medical injuries is the goal of medical development. At present, people's requirements for first aid measures have shown a trend from invasive to minimally invasive even non-invasive. It is a new requirement for emergency medicine in the new era to establish a minimally invasive emergency system and apply the minimally invasive technology in the first-aid and critical care area, to help the patients with acute and critical illness overcome difficulties, improve outcome, and enhance the quality of life.

Nanoplates-assembled SnS2 nanoflowers with carbon coating anchored on reduced graphene oxide for high performance Li-ion batteries

To meet people's requirements for higher performance Li-ion batteries (LIBs), many new types of anodes have been studied. Among them, the conversion reaction anode is considered to be a promising electrode based on the multi-electron reaction mechanism. As a typical conversion reaction anode, SnS2 has been widely explored for its advantages of low toxicity, easy synthesis, and high capacity. However, it usually occurs the shuttle effect of polysulfide when applied, leading to the irreversibility of the conversion reaction, and seriously hinders its application. Therefore, we firstly employed hydrothermal and low-temperature chemical vapor deposition technology to prepare a ternary composite that flower-like SnS2 anchored on reduced graphene oxide after coated carbon layer (SnS2/C-rGO). When applied in LIBs, SnS2/C-rGO displays a capacity of 952.8 mAh g−1 after cycling 90 times at 0.1 A g−1 and outstanding rate performance (479 mAh g−1 at 1 A g−1), which is significantly superior to other prepared electrodes. The high performance can be attributed to the synergistic effect of carbon layer and rGO, causing the high reversibility of conversion reaction and enhancing the cycle stability of SnS2. This investigation may provide a reference for improving the reversibility of conversion reaction anode.

The image inpainting algorithm used on multi-scale generative adversarial networks and neighbourhood

Various problems existed in the image inpainting algorithms, which can’t meet people's requirements visually. Aiming at the defects of the existing image inpainting algorithms, such as low accuracy, poor visual consistency, and unstable training, an improved image inpainting algorithm used on a multi-scale generative adversarial network (GAN) and neighbourhood model have been proposed in the paper. The proposed algorithm mainly improves the network structure of the discriminator, and introduces a multi-scale discriminator based on the global discriminator and the local discriminator. The multi-scale discriminators were trained on images of different resolutions. Discriminators of different scales have different receptive fields, which can guide the generator to generate more global image views and finer details. Aiming at the problem of gradient disappearance or gradient explosion that often occurs in GAN training, the method of WGAN (Wasserstein GAN) has been used to simulate the sample data distribution using EM distance. The proposed model has been trained and tested on the CelebA, ImageNet, and Place2. The experimental results show that compared with the previous algorithm model, the proposed algorithm improves the accuracy of image inpainting and can generate more realistic repairing images, and it is suitable for many types of images.

Function Analysis of Anti-haze Products Based on User Requirements

In recent years, due to the influence of environmental factors and human factors (transportation, heating, etc.), the frequency of haze in China is increasing day by day. And people's protective measures for haze are not in place. This paper uses the method of questionnaire and data analysis to determine people's demand for haze prevention products. 70.13% of the people living in haze areas are willing to buy anti-haze products. In haze weather, 38.7% of the people prefer to use anti haze masks, 27.3% of the people prefer to use air purifiers, and 16.1% of the people prefer to choose anti haze hangers. The two most important aspects that people focus on are haze prevention effect and wearing comfort. Gender differences influence the intention to buy anti haze products. People's basic functional requirements for wearing anti haze products are anti haze effect. Other requirements include wearing comfort, appearance, price and others, and others include sustainability and quality.

Citizens' preferences and attitudes towards urban waterfront spaces: a case study of Qiantang riverside development.

Many cities are facing various environmental problems, where performance-based planning and nature-based solutions have been proposed to address such problems. As a natural landscape in the city, urban waterfront space has efficient ecological benefits, high-quality landscape vision and environment, and it is an important carrier of citizens’ activities. However, existing studies have mainly focused on coping with environmental problems, while social functions and strategies have been neglected. Therefore, this study aims to fill such research gaps by understanding the social performance of urban waterfront spaces. Field observation and questionnaire survey were conducted in a famous urban waterfront space, Qiantang riverside walkway, in Hangzhou, China. The results indicate that the Qiantang riverside walkway serves as a space for tourism, leisure and entertainment, as the visitors who lived more than 5 km away from here accounted for about 50% and the local people also accounted for about 50%. People’s activities exhibited significantly temporal differences, where the occupation of the Qiantang riverside walkway reached a peak at night. For the people who lived far from here, they mainly depended on self-driving, which led to two critical problems relevant to transport linkage with the city and parking lot. Results also indicate that the landscape, supporting facilities and road functions could perform well among the mind of 102 respondents. However, public service and main facilities should be improved to meet more people’s requirements. Moreover, importantly, the results indicate the phenomenon of stratification and agglomeration so that the similar aspects (e.g. rest seat quantity, rest seat style) could be merged into the same cluster (e.g. rest seat) for consideration in the urban waterfront space planning and design. This study also generates some implications for the renovation of urban waterfront spaces. Overall, this study provides people with basic understanding of the social performance of existing urban waterfront spaces, which can further promote urban planners and designers to comprehensively build sustainable, resilient and healthy water-based living environments.

People’s adaptation to thermal conditions inside buildings for religious practice

Users of naturally ventilated (NV) buildings often try to adapt to maintain thermal comfort when thermal dissatisfaction is perceived, while this ability seems to be unnecessary for those living in air-conditioned spaces. Such a thermal subjective difference led to an establishment of the adaptive model, which was included in the ASHRAE Standard-55:2004 in 2004, to reflect thermal comfort requirement of NV-building users. Some forms of this American standard was officially adopted by Thai's Rating of Energy and Environmental Sustainability in 2012. However, its suitability for local application has remained questionable, thereby necessitating the need for more field-based research to gain a better understanding of local people's requirement for indoor thermal environments. This field research aimed to investigate users' adaptive thermal comfort using 517 datasets consisting of respondent personal information, subjective votes, and adaptive actions and thermal environmental data of three NV meditation halls in Thailand. The results reveal the inaccuracy of the predicted mean vote method. The respondents' neutral temperatures are higher than their thermal preference. Moreover, the 80% indoor acceptable thermal range in the study was slightly wider compared to a limit suggested by the ASHARE Standard. Regarding thermal adaptations, personal adjustments played a significant role in the first sequence of action, whereas psychological adaptations were more important in the later sequences.

Application of Electromechanical Installation Construction Technology in Practical Engineering

The impact of the coronavirus disease 2019 pandemic on the utilisation of emergency urological services.

ObjectivesTo compare the number of patients attending the Urology Emergency Department (ED) of the Centro Hospitalar Universitário do Porto (CHUP), as well as their demographic characteristics, the reasons for admission, the clinical severity under the Manchester triage system (MTS), and the need for emergency surgery or hospitalisation, during the coronavirus disease 2019 (COVID‐19) pandemic and the equivalent period in 2019.Patients and methodsData were collected from patients attending the Urology ED of the CHUP over 3 weeks, from 11 March to 1 April 2020, and from the same period in the previous year (from 11 March to 1 April 2019).ResultsDuring the pandemic, 46.4% fewer patients visited our urological ED (122 vs 263). There was no significant difference in the mean age or the number of old patients (aged ≥65 years) between the two periods. However, significantly fewer female patients sought emergency urological services during the COVID‐19 pandemic period (32.7% vs 14.8%, P < 0.05). No significant differences were noted between different clinical severity groups under the MTS. In 2019, significantly less patients required hospitalisation. The most common reasons for admission, during both periods, were haematuria, renal colic and urinary tract infections. The authors recognise that the study has several limitations, namely, those inherent to its retrospective nature.ConclusionCOVID‐19 significantly influenced people’s urological care‐seeking behaviour. Understanding the present situation is helpful for predicting future urological needs. Based on the results of this study, we have reason to speculate that people’s requirements for urological services might grow explosively in the post‐COVID‐19 period. There should be further studies about the real state of long‐term urological services and the consequences that this pandemic may have in terms of morbimortality not directly related to the severe acute respiratory syndrome coronavirus 2.

An exploration of stakeholders' perceptions of the extent to which the individual and collective views of patients with long-term conditions and their carers are heard and used to inform commissioning decisions within primary care.

Involving patients and carers in decisions that influence the delivery of health services is a statutory requirement across the NHS. However, current evidence suggests a gap exists between the theory, legislation and policy intentions and their practical implementation. This research aimed to identify the nature and extent of that perceived gap. Adopting a mixed-methods approach using questionnaires and semi-structured interviews, stakeholders' perceptions were explored regarding the extent to which the views of patients with long-term conditions and their carers are heard and used within primary care, across four clinical commissioning groups. Descriptive statistics were used to analyse the quantitative data; thematic analysis was applied to explore the qualitative data. Data analysis demonstrated considerable difference between patients' and carers' perceptions and those of healthcare professionals regarding how well involvement is implemented. Three key themes emerged that were perceived to influence the effectiveness of involvement. These related to the need for effective communication of relevant, accessible information that meets people's requirements; the need to take account of individuals' expectations, ability, motivation, assumptions, and previous experience; and the need for organisations to provide effective systems and processes, including adequate time and focused training to support involvement, in addition to robust monitoring and evaluation of the extent to which outputs from involvement influence commissioning decisions. The literature suggests that no existing framework addresses all three key themes. Therefore, a revised framework for involvement was developed, informed by the three key themes, that can be tested across a larger sample and different healthcare settings.

A Paper Based Milli-Cantilever Sensor for Detecting Hydrocarbon Gases via Smartphone Camera.

Hydrocarbon gases, especially toxic ones like benzene and xylene, pose threats to human health and the environment. But existing detection techniques, like bulky GC-MS or portable PID, cannot fulfill people's requirement of affordable and reliable hydrocarbons monitoring for the purpose of personal exposure assessment. Here, a simple, low cost, and light hydrocarbon gases sensor using a smartphone camera as a readout was developed based on the paper based milli-cantilever bending induced by polymer swelling. Its sensing cantilever was composed of three layers: functional layer of polyethylene film, adhesive layer of double-side tape, and a substrate of weighing paper. And the dimensions of the milli-fabricated sensing cantilever are 8 mm long, 0.5 mm wide, and 50 μm thick. The sensor response was the displacement of milli-cantilever free end. As proof of concept, its performance to typical hydrocarbons of xylene, hexane, and BTEX was carefully examined. For all of them, the sensor showed good performance of linear response to hydrocarbon concentrations, wide detection range, low detection, and fast response. Taking xylene for example, the sensor showed wide detection range of 15-140 ppm, low detection limit of 15 ppm, and fast response of 30 s. The sensor cross-sensitivity to other hydrocarbons was consistent with polymer swelling theory that the more carbons the hydrocarbon has, the higher the sensor sensitivity. Taking advantage of the rough materials chosen and simple fabrication procedure, the developed sensors also had high stability with time, low cost, and good uniformity. The developed sensor is affordable both physically and financially, has good performance, could meet hydrocarbons monitoring requirements for occupational safety or air pollution in petroleum industry, and would benefit people's health.
