In response to the problem that students cannot effectively master the theoretical knowledge of wireless sensor networks, this study proposes an outcome-based education (OBE) guided teaching method and designs a simulation experiment on wireless sensor networks using the NS3 simulation platform. In the experiment, access point (AP) and station (STA) nodes are set up to present different network environments, and the transmission layer protocols (TCP and UDP) are changed to analyze different network performance. Through the analysis of experimental results, students can gain a vivid understanding of the basic knowledge of wireless sensor networks and achieve the expected teaching goals. This teaching method helps improve students' understanding and application ability of wireless sensor network theory, and promotes their learning and research in related fields.

Railway structures, as heritage elements, are a special type that attracts little attention.In addition to the ancillary facilities serving the station directly, railway bridges and tunnels are generally located in the wilderness or inaccessible mountains and jungles and are often neglected.This paper mainly discusses the types, resource distribution, conservation status and western practice of railway structures, examines and excavates the heritage value of railway structures, and tries to provide basic research foundation for the overall conservation and sustainable development of railroad line heritage.

The village landscape is the material carrier of social and historical development, the living inheritance of traditional culture, and has obvious regional attributes.The intervention of art can not only improve the recognizability of the village landscape, but also enrich the art form and sustainable inheritance and development of the village landscape.This project takes "Bondage-Break- Transform-Rebirth" as the narrative context, based on solving the practical problems existing in village development, and puts forward the intervention strategy of art intervention in village landscape. Relying on the three artistic dimensions of space, time and image, the village landscape type is re-identified, so as to increase the recognizability of the village landscape. On this basis, the four construction steps of " 'Ding', 'Xuan', 'Zhi' and 'Zao' " are used to reconstruct the artistic appearance of the village landscape, so as to stimulate the vitality of artistic village landscape regeneration, and provide new artistic perspectives and new practices for the comprehensive implementation of the rural revitalization strategy in China.

Listed reserves are the lifeblood of oil and gas producers, so it is important to pay attention to their changes.There are many factors affecting listed reserves, among which production dynamic is one of the main factors affecting oil and gas fields in production.The evaluation practice shows that when the production dynamic becomes better, the listed reserves increase, while when the production dynamic becomes worse, the listed reserves decrease. In this paper, on the basis of the same amount of work, the influence of production dynamics on listed reserves can be determined by comparing the net production profile of developed old wells in the previous year and the current year after deducting the influence of economic factors. This paper shows how to determine the influence quantity of listed reserves under the common change of 8 different production dynamics and economic factors, and takes field B as an example to determine the influence quantity of current production dynamics on listed reserves, which again proves the positive influence of production dynamics on listed reserves. This will provide a cautionary tale for oil and gas field production management. Managing production dynamics will increase developed listed reserves, thus reducing the company's depreciation and amortization costs.

China adheres to the concept of green and sustainable development, and wind power new energy aligns well with this concept.At the same time, it has lower economic costs and strong adaptability.It is currently widely used in the development of many industries in China.As the demand for energy continues to increase in the process of social development, people are considering the development of new energy sources and making efforts to develop alternatives to renewable and traditional energy sources to alleviate the current energy crisis.Wind energy, as a green and clean renewable energy source, is becoming increasingly advanced in various related technologies.The efficient use of wind power new energy can alleviate the energy crisis, promote global economic growth, and make the wind power industry one of the most popular industries.However, in practice, the use of wind power as a new energy source still poses challenges that are not well-aligned with the economic development and safe operation of the power grid.

In response to issues such as weak generalization of extraction models and missing information in abstraction models in automatic text summarization, takes the patent specification and its abstract as the research object, a patent text abstract automatic generation model based on "extraction+abstraction", PatentSNU, is constructed. Combining the extractive summary model based on improved SummaRuNNer model with the abstractive summary model based on NEZHA-UniLM model, the output of the extraction model is taken as the input of the abstraction model, and the results of the extraction model are optimized by the abstraction model, and then get an accurate and concise patent specification abstract.The experimental results show that the content of the patent specification abstract generated by thePatentSNU model is comprehensive, the language is fluent, and it is closer to the reference abstract.At the same time, using the ROUGE score as the evaluation index, the PatentSNU model has a significant improvement in the ROUGE score compared with other benchmark models.

Fushun West Open Pit Mine is the largest open-pit coal mine in Asia, which has formed multiple large slopes after years of mining.These slopes have already occurred severe damage, causing serious impacts on mine production and resident life in the surrounding areas.This paper takes the rear edge slope of the southern slope of the Fushun West Open-Pit Mine as the research object, and conducts geological zoning and stability evaluation on it.The slope was divided into basalt area, ancient weathered crust area, and miscellaneous fill area based on its lithology, development of structural planes, and potential failure modes.The potential sliding surface of the slope was determined according to the field investigation and the slope type, and the parameters of the shear strength of the sliding surface were determined by the medium-sized shear test.Based on the limit equilibrium method, the stability of slope under natural, rainstorm and earthquake conditions were evaluated by various methods.According to the evaluation results, stability zoning was carried out on the rear edge slope of the southern slope, and corresponding treatment suggestions were proposed.This provides an important basis for the subsequent risk zoning and disaster management of the rear edge slope of the southern slope of the Fushun West Open-Pit Mine.

Reciprocating compressor is widely used in petrochemical industry, lubrication system is an important part of reciprocating compressor lubrication mainly includes crankcase and piston lubrication This topic is based on a certain oil and gas for gas compression of the reciprocating compressor, the crankcase of lubrication and the piston lubrication are independent of each other, and lubrication of piston USES oil lubrication, the oiler tank is small, and lubrication of lubricating oil is not recycled, need to add lubricating oil every day, cause compressor maintenance workload is bigger, aiming at this disadvantage, this paper has carried on the lub oil exploration process optimization, and It is a good operation practice and provides a new idea for the design and renovation of similar reciprocating compressor lubrication system.

The iterative problem of solving nonlinear equations is studied. A new Newton like iterative method with adjustable parameters is designed based on the dynamic system theory. In order to avoid the derivative function in the iterative scheme, the difference quotient is used instead of the derivative. Different from the existing methods, the difference quotient scheme in this paper has higher accuracy. Thus, the new iterative method is suitable for a wider range of initial values. Finally, several numerical examples are given to verify the practicability and superiority of the method.

Soma segmentation is crucial for subsequent analysis of brain images, and can be used for analysis of neuronal morphology and other aspects.Although the results of manual soma segmentation are more accurate, this method is very time-consuming and labor-intensive, so an accurate method of automatic soma segmentation is needed.Existing optical imaging images of the brain tend to be large, and one way we segment somas is to take the approximate coordinates of the center of the soma we need, then cut the image into small cubes one by one, and segment the somas in the small cubes.However, in this cube, in addition to the soma roughly located in the center that we want to segment, there are often other somas in the periphery, especially when they are close to our target soma, and some of them are only left incomplete during the cutting process.In addition, due to some defects of optical imaging and other problems, it leads to many images with low signal-to-noise ratio, which severely affects the segmentation effect.Therefore, we incorporate two mechanisms in the training of U-shaped convolutional neural network to alleviate the above problems, one is soma edge identification, and the other is the enhancement of multi-soma construction with soma shifted.Compared with existing popular medical image segmentation models, our method is significantly better in soma segmentation.
