Maritime data from the Automatic Identification System (AIS) have emerged as a potential source for real time information on trade activity.However, no globally applicable end-to-end solution has been published to transform raw AIS messages into economically meaningful, policy-relevant indicators of international trade.Our paper proposes and tests set algorithms fill this gap.We build world seaborne using radio signals that global vessel fleet emits navigational safety purposes.We leverage...
In this paper, we propose a smart water Long Range (Lora) Internet of Things (IoT) System allows operators to monitor systems in real-time. Applied through both wired and wireless detectors across the systems, it facilitates data analysis, supports user enquiry, timely access quality information. addition, ultrasound meter detects leakage improves efficiency usage. The alert system, along with detection hardware, uses machine learning solve problem service providers' operational efficiency....
The Momoge National Nature Reserve (MNNR) is located at the intersection of Nenjiang and Taoer Rivers in Baicheng City, Jilin Province, where River main source water for nature reserve. However, due to construction control project upper reaches River, MNNR has been a state shortage long time. To guarantee wetland function reserve, government planned carry out normal flood supply from through West Water Supply Project Province. Therefore, how improve utilization resources effectively become...
Effectively monitoring the real-time position and status of oil facilities (mainly well-site) in field is very important for safety production. Considering low efficiency traditional visual interpretation method high demands preset feature machine learning method, one object detection methods Deep (YOLOv2) was introduced to recognize industry automatically. After establishing dataset facility samples, 90 percent samples are used model training while 10 validating. Comparing with results...
In view of the real‐time and distributed features Internet Things (IoT) safety system in water conservancy engineering, this study proposed a new architecture for engineering based on cloud/fog computing put forward method data reliability detection false alarm caused by abnormal from bottom sensors. Designed South‐North Water Transfer Project (SNWTP), integrated project safety, quality human safety. Using IoT devices, fog layer was constructed between cloud server devices projects....
By three-link modal, the energy consumption pattern of oil pipeline system was divided into conversion process, transmission process and technological utilization process. The mathematical model analysis scheme optimization were established. And on basis .Net platform, with OLE DB database connection technology, software comprehensive developed which can be used as a tool to help manager manage more effectively.
The water injection system of large-scale oilfield is a very complicated pressure system, which consists several stations connecting with each other. At present, the suffers couple prevailing problems, for example, low efficiency and high power consumption, dispatching optimization operation serves as an important approach to solve such problems. mathematical model scheme oilfield's established minimum consumption objective function, restriction on hydraulic balance, rate constraint...
The test and contrast mortars were made by changing water-binder (water-cement) ratio from 0.4 to 0.6, fly ash replacing rate 10% 30% over-mass factor of 1.3 1.7 with different methods equal-replacing cement ash. variation compressive flexural strengths mortar admixing amount are analyzed based on the strengths. formulas for calculating active proposed, regularity change given out.
Abstract The emergency plans for water diversion projects suffer from weak knowledge correlation, inadequate timeliness, and insufficient support intelligent decision-making. This study incorporates graph technology to enable recommendations in projects. By employing pre-trained language models (PTMs) with entity masking, the model's ability recognize domain-specific entities is enhanced. leveraging matrix-based two-dimensional transformations feature recombination, an interactive...
In order to solve the prewarning problem of South-to-North Water Transfer Project safety, an intelligent cooperative method based on machine learning was proposed under framework information processing. Driven by monitoring data Project, single sensor in typical scenes studied, and security threshold predicted along vertical axis time, firstly. With support correlation calculation, sensors scene were intelligently grouped, study objectives changed into grouping, secondly. Then, nonlinear...
Objective To investigate the expression of Sirtuin1 (SIRT1) in brain tissue rats with different doses fluorosis-induced injury. Methods Forty-eight clean SD were divided into 4 groups based on body weight (90- 100 g) via random number table method: control group (normal feed containing fluoride 4.5mg/kg), low (feed 25.0 mg/kg), middle 50.0 high 100.0 twelve each group, half male and female. Rats drank tap water freely. Low, fluorine free to eat designated formulations raw coal mixed...
Centrifugal pump is an important kind of water injection equipment used to maintain reservoir pressure in oilfield development. The health condition evaluation centrifugal pumps helpful improve the operation and maintenance level. Although Analytic Hierarchy Process (AHP) fuzzy method are widely applied assessment, there still some problems, such as determination weight greatly influenced by subjective factors calculation complicated. To solve above this paper puts forward a catastrophe...
