The production of degradable polyglycolic acid from coal is a promising route for converting coal to high-end chemicals and can availably alleviate the problem of excess ethylene glycol. However, the traditional coal-to-polyglycolic acid (CtPGA) process wastes a lot of precious CO gases to adjust the H 2 /CO ratio, simultaneously producing a large amount of CO 2 emissions. To address this issue, this work proposes a novel coal-to-polyglycolic acid process integrated with green hydrogen from complementary wind and solar power (GHCtPGA). The complementary characteristics of solar and wind energy are investigated to generate green hydrogen. It is found that the hybrid power of wind−solar energy for the green hydrogen production process can significantly affect the capacity of the energy and hydrogen storage systems. After the modeling and simulation of the whole flowsheet of the CtPGA and GHCtPGA processes, the techno-economic and environmental performance of these processes is analyzed in detail. Compared with the CtPGA process, the GHCtPGA process reduces CO 2 emissions by 68.85% and improves carbon and exergy efficiencies by 11.57 and 2.72%, respectively. Furthermore, the economic performance of the GHCtPGA process is more satisfactory because its total capital investment is reduced by 11.32%, the total production cost is saved by 3.59%, and the internal rate of return is improved by 2.83%. Finally, a sensitivity analysis is conducted to explore the effect of coal price, electricity price, power consumption, and carbon tax on the economic advantages of the proposed GHCtPGA process. It indicates that the proposed GHCtPGA process has considerably stronger market risk resistance than the CtPGA process. Therefore, the proposed process provides a valuable PGA production route with low carbon, high efficiencies, and optimal economic trade-offs.

In signal processing applications, the multipliers are essential component of arithmetic functional units in many applications, like digital signal processors, image/video processing, Machine Learning, Cryptography and Arithmetic & Logical units (ALU). In recent years, Profuse multipliers are there. In that, Vedic multiplier is one of the high-performance multiplications and it is used to signal/image processing applications. In order to ameliorate the performance of this multiplier further, by proposed a novel multiplier using hybrid compressor. The proposed hybrid compressor-based multiplier is designed and implemented in Field programmable Gate Array (FPGA—spartan 6). The synthesis result shows that the speed of proposed hybrid compressor-based multiplier gets improved as compared to Array multiplier (35.83%), Wallace tree multiplier (34.58%), Vedic Multiplier based on Carry look ahead adder (CLA) (28.49%), Vedic Multiplier based on Ripple carry adder (RCA) (20.65%), Booth Multiplication (21.65%) and Vedic Multiplication based on Han-Carlson Adder (HCA) (20.10%) and Hybrid multiplier using Carry Select Adder (CSELA) (17.81%) and Hybrid Vedic Multiplier (7.15%).

In this study, an FPGA(Field Programmable Gate Array)-based borehole strain measurement system was designed that makes extensive use of digital signal processing operations to replace analog circuits. Through the formidable operational capability of FPGA, the sampled data were filtered and denoised to improve the signal-to-noise ratios. Then, with the goal of not reducing observational accuracy, the signal amplification circuit was removed, the excitation voltage was reduced, and the dynamic range of the primary adjustments was expanded to 130 dB. The system’s online compilation function made it more flexible to changes in measurement parameters, allowing it to adapt to various needs. In addition, the efficiency of the equipment use was enhanced. The actual observational results showed that this study’s FPGA-based borehole strain measurement system had a voltage resolution higher than 1 μV. Clear solid tides were successfully recorded in low-frequency bands, and seismic wave strain was accurately recorded in high-frequency bands. The arrival times and seismic phases of the seismic waves S and P were clearly recorded, which met the requirements for geophysical field deformation observations. Therefore, the system proposed in this study is of major significance for future analyses of geophysical and crust deformation observations.
