Comprehensive Evaluation of Source Rocks Characteristics in Yiliping Area, Qaidam Basin
Authors: Wang Xintong 
Published: May 2021

Abstract
Yiliping area in the middle of Qaidam Basin is a key area for oil and gas exploration in Qinghai Oilfield in recent years. However, the geochemistry characteristics of source rocks in Neogene are relatively vague, which results in the inaccuracy of hydrocarbon resource potential. Based on the seismic interpretation, well logging results, and analytical tests, the comprehensive characteristics of Neogene source rocks in the Yiliping area have been studied. The results show that the distribution of source rocks varies widely. The kerogen type is II2-III. The total organic content is from 0.2% to 1.96%. The vitrinite reflectance (Ro) is from 0.5% to 1.2%, which reflects a mature stage. The content of (S1+S2) varies from 0.01 mg/g to 89.66 mg/g. Through the comprehensive analysis, the Yiliping area is qualified for hydrocarbon generation, but has a fair resource potential. In the future, it can be considered to exploit when the cost of oilfield development is reduced.

Multi-Objective Optimized Operation Model Based on Demand Side Grid
Authors: Wang Qingran 
Published: May 2021

Abstract
The multi-objective optimized scheduling model is proposed considering demand side management. The load side resources are divided into nine categories based on three characteristics of fixed, transferable, and user-action loads. The management of transferable load is especially significant based on the example calculation in many regions. In the case of time-of-use price, the multi-objective optimization scheduling method with the objectives of minimizing the total operation cost of demand side energy grid is established. The economic utilization scale is calculated based on the collaborative utilization mode of user side resources and power supply. The numerical tests for the micro-grid indicate that with demand side management consideration, the total cost reduces significantly.

With the advent of the knowledge economy era, the application of energy big data has gradually emerged, and smart energy has begun to receive widespread attention. Decision analysis in the energy sector is fundamentally different in frequency, breadth, and complexity compared to the past. Traditional decision analysis techniques cannot meet the increasingly fierce market competition and corporate needs. Applying artificial intelligence technology into the energy field, realizing intelligent analysis and in-depth mining of energy big data, and providing better scientific decision-making have become a problem worthy of in-depth study in the new era.

Abstract
Oil chromatographic analysis (DGA) is an important way to transformer fault diagnosis, combining research topics based on I-K-means clustering, t SNE visual clustering in data mining, fault classification number. In order to improve the convergence speed of neural network, an improved back-propagation BP neural network using ADAM gradient optimization algorithm instead of traditional stochastic gradient descent optimization to update the weight of neural network is proposed. Fuzzy C-means clustering and particle swarm optimization are proposed to optimize the initial parameters of neural network. By using 3500 data samples of transformers from a power plant in a city of Liaoning Province to carry out simulation experiments, and comparing the traditional BP network algorithm, CPSO-BP network algorithm and the CPSO-BP network algorithm optimized by Adam, it is proved that the CPSO-BP network optimized by Adam has fast training convergence, strong generalization ability and high accuracy. At the same time, the accuracy, precision, recall and F-1 values were used to evaluate the CPSO-BP network algorithm optimized by ADAM to verify the effectiveness and stability of the algorithm in transformer fault diagnosis.

Authors: Yongbo Hu , Nie Dezhi 
Published: May 2021

Abstract
In 2020, a droplet-based electricity generator (DEG) was proposed. Compared with the traditional water drop generator structure, the voltage and current generated by the DEG structure are much higher. In our work, an aluminum electrode with a superhydrophobic surface was prepared by electrodepositing an aluminum substrate in an organic electrolyte. This electrode is applied to the DEG friction generator to optimize the coupling process between the surface water droplets and the DEG structure, which reduces the residual water droplets while maintaining the same level of electrical output characteristics. And the model of the solid-liquid coupling is also discussed.

A Study of Factors Influencing Wood Decay and Fungal Activities Based on Mathematical Modelling Methods
Authors: Liu Yuxin , Shi Yinyao 
Published: May 2021

Abstract
This paper establishes a series of mathematical models to describe the wood decay by fungi and important factors affecting fungi activities. First, it is assumed that the external environment will not change; by doing so, a simplified model was established. In continuous time intervals, the model took two situations into account – only single species involved and only multiple species involved. We then used the logistic model to describe the growth rate of fungi. In the situation of multiple species, we also considered competitions between different species. Given the initial area, combined with the relationship between fungal growth rate and decomposition rate, a simplified lignin decomposition model was established. On the basis of this model, a graph of the expansion rate and decomposition rate of different fungi over time was drawn, describing the decay effect of a single fungus and multiple fungi on wood in two different time ranges, short-term and long-term. When multiple species involved, competition between each fugal strain will also be considered. Secondly, considering the complexity of the environment in reality, we include two factors – temperature and moisture – into our model. These two would significantly affect fungi’s activities. Based on the research of Dianel S. Maynard and others, we establish a linear model-The Temperature and Moisture Change Model-to describe the impact of temperature and moisture. We also apply the model in five regions of different climatic characteristics and compare the growth rate and decomposition rate of different fungi to these five regions.

Abstract
An Eco-friendly Housing is an alternative choice of housing emerged along with the development of environmental discourse. The environmental discourse is commodified in the process of producing spatial space to increase the value of the product mark, which is the house. Commodification is defined as turning non-commodity goods into a commodity goods or adding value to a commodity goods, thus the value is more valuable than before, and it can be traded for profit.
This study used a descriptive research with a qualitative approach to describe the current phenomenon taking place. The study was conducted in the Bukit Baruga Housing, Makassar, which is a housing developed with the concept of an environmental insight since 1996.
With knowledge related to environmental discourse and power over capital possessed by the development company, it presents a simulation spaces with various signs and symbols of environmental insight. The process of commodification is carried out by the developer company through three stages, which are the stage of planning and development, marketing, and management.
