Chest pain is sudden, its pathological causes are complex and various, fatal or non-fatal so that improving the diagnostic accuracy is extremely important in the emergency system of prehospital and hospitals. Therefore, we propose a method of introducing a decision tree, support vector machine, and KNN algorithm in machine learning into the auxiliary diagnosis of chest pain. First select the algorithm with better performance among decision tree, support vector machine, and KNN algorithm; Then compare the classification performance of the CART algorithm, the support vector machine using the Gaussian kernel function, and the K nearest neighbor algorithm using the Euclidean distance to select the best; Finally, through the analysis of the experimental results, the support vector machine algorithm with Gaussian kernel function is obtained. Its detection time and diagnosis accuracy rate are the best among the three algorithms, which can assist medical staff in the emergency system to carry out targeted chest pain diagnosis.

Measurement uncertainty is one of the most important concepts. The ISO IEC 17025:2005 standard: describes harmonized policies and procedures for testing and calibration laboratories. Guide to the expression of uncertainty in measurement (GUM) is a direct uncertainty analysis method, which calculates the combined standard uncertainty and expanded uncertainty by law of propagation of uncertainty. Monte Carlo Method (MCM) as presented by the (GUM S1) involves the propagation of the distributions of the input sources of uncertainty by using a model to provide the distribution of the output. By random sampling, the probability density function of the input quantities. In this paper, present measurement uncertainty to circular runout error. By use shaft standard with a diameter of 32 mm., length 100 mm. From the experiment results, Comparison of GUM and MCM showed no differences. The cases the estimated uncertainty using the GUM approach slightly overestimated the results obtained with the MCM. However, the use of numerical methods such MCM as a valuable alternative to the GUM approach. The practical use of MCM it has proven to be a fundamental tool, being able to address more complex measurement problems that were limited by the GUM approximations.

This paper analyzes the research status of 3S technology in China's wetlands. The research of 3S technology in wetland landscape pattern and driving force analysis is increasing day by day. Most of the research uses 3S technology to calculate the landscape index, and reveals the change rule of wetland landscape pattern characteristics with natural and human factors from the type scale and landscape scale. The use of 3S technology for wetland information extraction and dynamic monitoring research is gradually increasing. In most studies, wetland information was extracted according to different classification criteria, and spatio-temporal characteristics of wetland were analyzed based on area change, spatial distribution and shape change. With the development, planning and protection of wetland resources, the advantages of 3S technology will become more prominent.

Through the expansion of Industry 4.0, the Oil & Gas industry in the world is undergoing a major transformation, so that the formalization of a process chain for the manufacture of spare-parts becomes increasingly necessary. This work aims to create work patterns using the concepts of industry 4.0 applied to the Oil & Gas industry, through the study of several work- pieces of this area. All spare-parts were used to create a chain of manufacturing processes. From there, they were recreated through different digital or hybrid manufacturing techniques. Several points such as geometry, type of acquisition of geometry, types of raw materials, types of manufacturing technology and machinery were addressed. Mechanical tests were carried out at different stages of the process. The results obtained formed a basis for strategies aiming solving problems of the studied spare-parts, using hybrid and additive manufacturing techniques, combined with the concepts of Industry 4.0. The created protocol was a descriptive and detailed standardization of the production chain process. The evaluation of the processes, justifications and solutions was applicable for each demand, generating a virtual catalog of spare-parts and that fed a cyclical model of experiences that continually update the database itself.

Traffic congestion has become a major concern, aroused as a result of increased population and urbanization. Hence, novel and innovative methods for controlling ever-increasing traffic volumes are essential. Conventional traffic light schemes are the most popular method of controlling traffic, and it is logical and economical to make research endeavors to optimize their existing performance. Despite numerous studies, the aforementioned problem has not been optimally and sufficiently solved. In this research, we introduce an adaptive traffic signaling scheme based on vehicle density to facilitate optimal traffic signal control as well as effective traffic management. We also propose effective coordination of the traffic amongst the junctions. Here, the live video is utilized as an input provided to a deep Q network to provide adaptive phase timings as the output. In the proposed scheme, we introduced per car unit (PCU) as a novel parameter to represent the effect of each vehicle type on traffic conditions. Numerous filed trials on real-time data amply prove that the proposed scheme enhances the average speed of traffic up to 5.597 km/h. The proposed scheme shows an average increment of 175.71% in average mean speed compared to the existing static schemes. Except for the high traffic scenario, for both mid traffic and low traffic scenarios, the proposed scheme shows a considerable improvement in both average densities and maximum densities. In the mid-traffic scenario, the average speed shows an improvement of 3.85 km/h, while in the low traffic scenario, the average mean speed shows an improvement of 7.96 km/h. A reduction in fuel consumption and average delay were also observed, which will lead to a greener Transport 4.0.

Supporting force, that a rod receives from the ground, is increased when vibration gives to the ground. This phenomenon is effective to improve the running performance for the legged rovers. In this study, the flow of the ground particles when a rod is dragged is measured using PIV for improving the running performance of the legged rovers. As observed from the experimental result, the larger the supporting force is, the larger the area that the particles move is. Therefore, the supporting force is related to the movement of the ground particles. Moreover, the area that the particles move becomes large by providing vibration whose frequency is high. The reason is considered that density is increased in a wide range of the ground when the vibration whose frequency is high. It is considered that the supporting force is increased by providing vibration to the ground because the area, that the particles move, grows by increasing density of the ground. The findings of this study suggest facilitating further planetary exploration using legged rovers.
