Published: February 2022

Abstract
Clean energy has the potential to deliver universal energy access in a way that is safe and powers bettering the environment for everyone. Photovoltaics, which transfer solar energy to electrical energy, can generate clean energy. This article introduces the internal structure, function, and working principle of each part of the system after combining photovoltaics and OLEDs. Then, this article concludes with some advantages: the system’s energy source is clean energy and the system’s other expanded applications. This new material-plastic electronic also faces some challenges. For example, solar energy received by the system is affected by factors such as latitude, which affects sunshine hours in a particular region, and weather, which affects light intensity. Moreover, there are several concerns like battery thermal management and battery life in practical application scenarios. So, this article needs to do more research and further experiments to improve the efficiency of solar power and maintain the health of the battery. In the future, this article suggests doing regular experiments to observe the system’s efficiency and find the direction for improvement.

Authors: Xiao Xiao , Xiong Gui , Dang Hao 
Published: February 2022

Abstract
Bonding has many advantages such as high adhesive strength, peel resistance, good toughness, shrinkage and corrosion-resistance, compared with bolting, welding and other connection patterns, which is the basic connection of the composite materials. The mechanical properties of the bond depend on the type and geometric parameters of the bond. In this paper, experiments were conducted to study the bond strength failure of GFRP single and double lap joints and explore related influencing factors. The variable factors of test specimens include bond type, length and thickness. The quasi-static tensile test was carried out at room temperature to analyze multiple influencing factors of lap joints and characteristic of GFRP bond failure strength. The results showed that the failure of the bond usually occurred at the interface of bond, and bond types, length and thickness have significant effects on the failure of bond. Failure strength increased firstly and then decreased with the increase of adhesive thickness. With the increase of bonding length, the failure mode of the double-lap joint become complex failure mode, which is accompanied by GFRP delamination near the surface of fiber of the bonding.

Authors: Han Guoqing , Yan Shuang , Chen Zejie , Chen Lin 
Published: February 2022

Abstract
Microseismic event detection helps to predict outbreak catastrophic problems and has essential applications in resource exploration. Low SNR microseismic signal detection is a challenging task in microseismic detection. In this paper, we propose a (convolutional neural network microseismic detection method based on variance fractal dimension) VFD-CNN method based on the variance fractal dimension (VFD). In this method, signals and background noise are first measured by variance fractal dimension, which can effectively extract seismic nonlinear features. These fractal features are then fed into VFD-CNN to distinguish signal and noise. Finally, the variance fractal dimension of the test data is fed into the optimal model to detect microseismic events. The VFD-CNN method can significantly improve the detection capability of low SNR microseismic signals. To verify the performance of the VFD-CNN method, We use the VFD-CNN method to synthesize microseismic data. Furthermore, the comparison experiments were conducted using VFD-CNN and short-term averaging to long-term averaging (STA/LTA) algorithms. The results show that the VFD-CNN method can significantly improve the detection of low SNR microseismic signals, and its precision is substantially higher than the STA/LTA algorithm.

With the development of industrial information technology in recent years, gesture control has attracted wide attention from scholars. Various gesture control methods have emerged, such as visual control, wearable device control, magnetic field feature extraction control. Based on one of the visual gesture control methods, this paper proposes a visual gesture control method applied to music box control by combining YOLOv4 object detection network.

Authors: Su Dongchu , Yang Jian , Yuan Chunxing , Chang Bowei , Luo Siwei , Li Chenyong 
Published: February 2022

Abstract
Resolution Band Width (RBW) represents the 3 dB bandwidth of the internal IF filter of the spectrum analyzer, the setting of which greatly affects the clarity of the output spectrum line of the spectrum analyzer. Its reasonable value is essential to correctly distinguish the signals of different frequencies, especially in the case of aliasing of the output spectrum. Thus, it is of great significance to study the relationship between the setting of RBW and the output spectrum. Due to the expensive spectrum analyzer, the RBW adjustment range, frequency range and output accuracy are limited, so this paper will apply an economic, RBW arbitrary adjustable, high accuracy equivalent convolution method for the simulation of the RBW parameters of the spectrum analyzer, and evaluate the effect of RBW and filter type on the degree of output spectrum aliasing based on a typical equal-amplitude two-tone signal input, and finally give setting suggestions on RBW and filter type.

Abstract
With the miniaturization of RF circuits, the transmission of signals in different layers becomes important. How to realize the vertical transition structure with wide transmission band and low loss has become the focus of research. In this paper, we proposed a broadband vertical transition structure design based on cavity coupling. This model achieves broadband coupling between the upper and lower microstrips by adding parabolic patches, which improves the model transmission bandwidth. The simulation results show that the optimized model has ultra-wideband transmission characteristic, the 1dB bandwidth is 3.32 GHz-10.42 GHz and the fractional bandwidth is more than 103%. What’ more, the thick ground layer of the model improves the heat dissipation performance. Therefore, this structure is very suitable for high-speed and high-density RF circuits.

Abstract
Aiming at the problem that Yolov5 is difficult to accurately detect backlighting and small samples in national grid power transmission and distribution operations, studies the illegal behavior technology of “two wear and one wear” in power grid operation, and proposes a violation recognition algorithm based on the enhanced YOLOv5. First, add a new detection layer and use the BiFPN (bi-directional feature pyramid network) layer for feature fusion, so that feature layers of different scales can better learn the weight distribution and enhance the fusion ability. Secondly, add CBAM (Convolutional Block Attention Module) module before the output detection layer feature map to make full use of channel and spatial information to achieve better model accuracy and recall. The experimental results on the six self-made data sets show that the mAP of this method is 91.0%, which is 5.6% higher than the original algorithm, indicating that the model has stronger predictive ability and robustness for the identification of personnel and safety tools in transmission and distribution scenarios.
Sustainable Natural Solar Drying of Microbreweries Spent Grains: A Comparison with Common Electric Convective Drying
Authors: Fabani MP , Capossio JP , Reyes-Urrutia A , Rodriguez R , Mazza G 
Published: February 2022

Abstract
In recent years, local microbreweries are increasingly capturing the consumer’s interest with a wide range of different types of beer. Because of the insertion of microbreweries scattered around the country, large amounts of spent grains have been made available locally to be used, for instance, as animal feed. However, those spent grains, which are mainly formed by malting barley (or malt), are materials suitable for further valorization. Turning the spent grains from waste to a raw material that can be later used to produce non-traditional flour requires a thermal treatment, i.e. a drying process. A natural convection solar dryer (NCSD) was evaluated as an alternative to a conventional convective electric drying system for the dehydration process of local microbrewer’s spent grains. Two types of breweries’ spent grains-BSG-(Golden Ale and Red Ale) were dried at different daytime hours. Sustainability indexes, Specific Energy Consumption (SEC), and CO2 emissions of the conventional dryer were calculated and used to determine the environmental benefits and drawbacks of the NCSD.
