A stand-alone photovoltaic (PV)-Battery energy storage system (BESS)-Genset (PV-BESS-Genset) connected microgrid model, utilizing measured solar irradiation data, real-time manufacturer data for technology components, case study area daily energy consumption data, and a bottom-up approach to model demand response.
Mali Zheng [13] proposes a genetic algorithm optimization method for the energy reduction control of building air-conditioning systems.
Data collection and system components modeling Electrical load In this paper, electric appliances used to carry out a specific household task (lamps, television, computer, cooking stoves, etc.) are loads.
And a 10% day-to-day and 15% time step-to-time step random variability were adopted with the study to improve the realism of the load data.
With the help of primary data from the case study site, this study modeled a roof-top solar-powered microgrid for residential real estate.

Measurements were repeated until 100 data were obtained for each electrode.
Graphite powder that has been functionalized produces -OH and -COOH groups, based on the data taken using FTIR, which can be seen in Fig. 3.
Conductivity has been obtained by taking the voltage data from each sample using four-point probe (FPP) method, and the voltage data has been listed in Table 3.
Dimensional measurement data for each sample are presented in Table 4.
Resistance and conductivity data for each sample have been presented in Table 5 below: Table 5.

With the lightning position data in recent years of Jiangsu, satellite and live data on 3rd,July,2012, the reasons for the damage to office room equipment beside a communication base station in Wujin District, Changzhou were analyzed, and reasonable suggestions were given.
As the lightning location system itself had certain error, generally, meteorological data and the accident location was consistent which meant the accident was caused by lightning strike.
Fig.1 Weather on 3rd,July 1.2.2 Lightning strike probability After analyzing the data of lightning location system in Jiangsu province, we got that annual average flash density was 3.4 number/km2a, the average amplitude of lightning current was 31.93kA, 1% of the lightning current amplitude was more than 97.40kA in the range of 5*5km around the communication tower from 2006 to 2011.
Summary Commined with the lightning data in Jiangsu recent years, take the communication base station in Wujin as an example, this paper analyzed the accident from weather, lightning strike probability, lightning protection effectiveness, potential and current situation of lightning protection, the results are followed.

The goal of an ERP-based integrated information system is to make the system effective and efficient (e.g. by reducing data redundancy and maintaining the data flow through company).
However, this MRP procedure requires the declaration of period for data analysis and is based on the average demand for the assumed period.
The data set (52 weeks) has been divided into two sets: learning (L) – 42 samples and testing (T) – 10 samples.
The testing set includes data for each fifth week (i.e. 5, 10, 15, etc).
The material demand and inventory forecasts are based on the data from an ERP system and can be assigned to MRP procedure.

Table 1: Key data on the rheological preparation of the samples
Sample No.
The data acquired for the study at hand was first median filtered and thresholded.
A top view on the volume data of the cylindrical samples is shown in Fig. 2.
The result for sample 4 compared to the original data is shown in Fig. 4.
After approximating the additional particle layer, it was removed from the volume data.

When the grain size is in the vicinity of Lcrit=21.5nm, the effective anisotropy constant Keff
was calculated by Herzer model(see the data in Table 1).
It can be seen that the variation character of effective anisotropy constants Keff along with the reduction of grain size, D, are very similar for the series curves.

The rapid temperature change at thermal shock first leads to the formation of incipient macroscopic cracks due to the growth of microscopic defects and then to the reduction of the residual strength due to further thermo-mechanical loading cycles.
Various methods have been developed in recent years to predict thermal shock resistance, partly based on experimental data, partly purely theoretical.

Introduction
In the electron-doped superconductors Nd2−xCexCuO4+δ superconductivity depends not only on the number of doped carriers putting into the cooper oxygen planes but on the additional oxygen reduction.
The amplitude of the anomalous RH(B) peak depends on temperature, decreasing with its lowering in accordance with literature data [4,6,7] and vanishes at T £ 1.6 K.

Introduction
Interest points are spatial features of the image that capture information from their neighbors, are distinctive and stable under transformations such as translation and rotation, are helpful in data reduction, and reduce the computational burden of various algorithms such as image registration by replacing an exhaustive search over the entire image domain by a probe into a concise set of highly informative points.
