Research on EA-Xgboost Hybrid Model for Building Energy Prediction
Authors: Yucong Wu , Bo Wang 
Published: May 2020

Abstract
Building energy forecast plays an important role in Intelligent Building. Due to its non-stationarity and uncertainty, the prediction accuracy of existing methods need to be further improved. In view of this problem, propose the EA-XGBoost model, which combines Empirical Mode Decomposition (EMD), ARIMA and XGBoost model to predict building energy consumption. First, EMD is used to decompose the consumption data into multiple Intrinsic Mode Functions(IMF). Afterwards, ARIMA model is applied for each IMF to get regression result, then sum the results and calculate the residual. Taking the residual as an input feature of XGBoost, combined with other energy-related factors such as dry and wet bulb temperature, using XGBoost after Grid-Search to predict building energy consumption data. Compared with ARIMA and XGBoost model, EA-XGBoost hybrid model performs best in forecasting building energy consumption dataset which provided by the US National Renewable Energy Laboratory. The experiment shows the feasibility and effectiveness of the new model.
Studying problems on choosing stable orbits of nanosatellites to provide passive and periodic relative trajectories
Authors: Shcherbakov M.S. , Avariaskin D.P. 
Published: May 2020

Abstract
The paper considers the passive perturbed inspection movement of one nanosatellite (NS) relative to another. The inspection movement is considered in local vertical local horizontal associated with the inspected NS moving in a near-circular low Earth orbit. NS2 has an inspection movement around NS1. Under the influence of J2 perturbation the real movement diverges from the inspection one and the relative trajectory of satellites becomes open. The paper shows that by choosing the initial conditions of both NS motion, the perturbation of the inspection motion can be reduced. As strict J2 invariant trajectory conditions exists [1] to provide quasi-periodic relative orbit [2], the perturbed inspection movement will slightly differ from the reference trajectory. Thus, NS can fulfill the target task without orbital correction for a certain time interval. Paper provides analytical relations for the conditions of quasi-periodic relative orbit and a methodology for selecting the initial conditions for the NS motion.

Authors: Konovalov S.F. , Mayorov D.V. , Rusanov P.G. , Chulkov V.E. 
Published: May 2020

Abstract
The paper is devoted to azimuth correction system of an inclinometer used for well drilling in high latitude areas. In these areas, ordinary types of navigation equipment (gyroscopic and magnetic sensors) are ineffective because of small horizontal component of the Earth rotation velocity and significant values of magnetic declination. In the paper, an approach to the correction system study is described. The system consisting of two vibrational sources shifted from the wellhead to a certain distance in the direction of projected drilling and spaced to same distance from the specified direction is characterized.
Special attention is given to investigation of a motion model of a flexible shaft, which is proposed as the vibrational source of the system. On the basis of experiments and calculations, it is shown in the paper that in a complex mechanical system with a flexible shaft of vibrational source, a consistent multi-resonant effect can be observed when the shaft starts rotating. Moreover, a simulation model and results of estimation of the vibrational source power are presented. A possibility of use a compact “handheld” vibrational source with flexible shaft for azimuth correction system operation is shown

Published: May 2020

Abstract
The performance characteristics of glued materials based on thermo-modified veneer depend on the heat treatment mode. The choice of a mode that does not lead to a decrease in the strength of plywood allows reducing water absorption and swelling by a value from 20,4 to 33,5 %. Plywood based on thermo-modified veneer acquires higher strength and water resistance, which significantly expands the range of application of laminated wood based on urea-formaldehyde resins.

Description of wildfires spreading and extinguishing with the aid of agent-based models
Authors: Dorrer G A , Yarovoy S V 
Published: May 2020

Abstract
The article describes a new method of describing wildfires spreading and extinguishing based on agent-based models. The agent approach in conjunction with geoinformation systems (GIS) permits to efficiently describe the interaction of a big number of participants of wildfire fighting: spreading fire, fire brigades, means of mechanization, air means, etc. In the current paper, this approach is illustrated by an example of two types of agents denoted as A and B. The burning fire line is seen as a chain of type A agents, each of which imitates burning of an elementary area of vegetable fuel. The fire line movement is described by Hamilton–Jacobi equation and is calculated based on the moving grid algorithm. Agents of another type—B-agents—describe fire extinguishing, they approach the agents of A type and affect them decreasing fire intensity to zero. This model is presented by a GIS-oriented software system which may be enhanced and be useful both for fire control management and training personnel in wildfire fighting tactics.

Analysis of the secondary emission current and X-ray radiation dependency on the beam’s position along the joint during electron beam welding
Authors: Braverman V Ya , Bogdanov V V , Oborin L A 
Published: May 2020

Abstract
We analyzed secondary emission current and X-Ray radiation dependency on the beam’s position along the joint during Electron Beam Welding of similar and dissimilar materials. We established that those characteristics were identical if the welding rim melting was absent. The characteristics are of extreme nature. During the welding of similar materials, the dependency minimum corresponds with the precise alignment of the beam’s position and the joint. During the welding of dissimilar materials, the minimum of the secondary emission current shifts towards the material with the lowest coefficient of the secondary emission and the minimum of the X-ray radiation shifts towards the material with the lowest atom number. The similarity of the characteristics is explained by the fact that the appearance of the secondary emission and the X-ray radiation is the result of the electron beam’s interaction with the material of the welded parts. Therefore, we can use the same mathematical tool to analyze the dependencies and joint tracking devices can be designed with unified hardware and software applications.

Published: May 2020

Abstract
Widespread clinical adoption of photodynamic therapy (PDT) and photobiomodulation (PBM) has been limited due to the lack of a suitable commercial light source. Cost-effective quantum dot light-emitting diodes (QLEDs) promise to be an ideal light source nicely fitting into this niche, not only complying with desired form factors—flexibility, lightweight, and uniform large area illumination—but with narrow emission spectrum and high power density at clinically relevant deep red wavelengths. This paper is intended to provide a review on the development of QLEDs as a photomedical light source, specifically, for PDT and PBM. First, we introduce the potential of QLEDs as light sources in the photomedical field, briefly describe the mechanisms and benefits of both PDT and PBM phototherapies, and present the unique features of flexible QLEDs (FQLEDs) over conventional and commercial light sources. Then, the pioneering work and state-of-the-art research using QLEDs and organic light emitting diodes (OLEDs) for photomedicine are presented. The performance of QLEDs/OLEDs used in photomedical studies and latest progress on QLEDs are also summarized. Ultimately, we discuss the materials and design strategies for fabrication of efficient and stable FQLEDs, and present the basic requirements for near future introduction of FQLEDs into the healthcare and photomedicine markets. This review is expected to be comprehensive and useful to the scientific community interested in developing lightweight and flexible light sources for photomedicine and/or exploring novel applications for OLED/QLED based lighting devices.
