The paper deals with the analysis of observational data in the assessment of the situation developed technique of heterogeneous data operational processing in assessing situation with the help of Geographic Information systems, which allow to store raw data about surveillance objects, structured heterogeneous surveillance data due to the principle "Data Lake".The basis of the technique is the Model of Storage of Heterogeneous Data, which differs from the known ones by the presence of templates of objects of observation and templates of parameters of objects of observation, which allow distributed storage of both unstructured heterogeneous data and structured data according to a certain scheme, to access data.
This paper focuses on closed loop operational mode of Volt-VAr control (VVC) algorithm, as well as the power flow (PF) methods that can successfully be used to implement VVC. Two methods to implement efficient PF are ...

the paper proposes a design method for online monitoring of transmission lines based on sensors and LPWAN technology. In this design method, Utilize the low power consumption and long-distance transmission characteristics of LPWAN communication technology, combined with temperature sensors, air pressure sensors, temperature and humidity sensors, and three Axis accelerometer, wind speed sensor and nine-axis position motion sensor, different online monitoring units are designed, and the real-time monitoring of the inclination of the pole tower, the temperature, the galloping, the sag, the icing of the wire are realized. Through the optimized design of software and hardware, each monitoring unit maintains a low power consumption level, and it can work stably and continuously for 3 years with battery. After laboratory and simulation verification, the design target is achieved. The design method can be applied in actual scenarios after optimization and engineering.

Daily activities has become leading problems in human physical analysis. Autonomous system as application in several area of human physical analysis was increase along with several machine learning methods. Fall detection, medical rehabilitation or other smart home application in physical analysis application has increase degree of life. Accelerometer and gyroscope was popular sensor for physical analysis. Several research was used these sensor with various position in human body part. Activities was separated in three class, static activity, transition activity, and dynamic activity. Basic activities has same pattern in each activity. From public HAR dataset, wich have three static activity (standing, sitting, and laying) each pattern has same shape and patterns. Dataset were used in this paper have acquire from 30 volunters. Seven basic machine learning alghoritm Logistic Regression, Support Vector Machine, Decission Tree, Random Forest, Gradien Boosted and K-Nearest Neighbor. The purposed method Logistic Regression achieves 98% accuracy same as SVM with linear kernel, with same result hyperparameter tuning for both method has same accuracy. Likewise for result where this main problems static activity was successful detected with logistic regression and SVM.
