A micro air vehicle with a bird-mimetic up-down and twisting wing drive system was developed in this study. The Flap- ping-wing Micro Air Vehicle （FMAV）, with a 50 cm wingspan and a double-crank drive system, performed successful flights of up to 23 min. The performance and capabilities of the FMAV were enhanced by adapting a number of unique features, such as a bird-mimetic wing shape with a span-wise camber and an up-down and twisting wing drive mechanism with double-crank linkages, This lift-enhancing design by mimicking the flapping mechanism of a bird＇s wing enabled the 210 g FMAV to fly autonomously in an outdoor field under wind speeds of less than 5 m.s-1. Autonomous flight was enabled by installing a flight control computer with a micro-electro-mechanical gyroscope and accelerometers, along with a micro video camera and an ultralight wireless communication system inside the fuselage. A comprehensive wind tunnel test shows that the FMAV with a high-camber wing and double-crank mechanism generates more lift and less net thrust than the FMAV with a flat wing and single-crank mechanism, which confirms the improved performance of the developed FMAV, as well as the superior slow flying or hovering capabilities of the FMAV with a high-camber wing and double-crank wing drive system.

Co-pyrolysis gas produced from the co-pyrolysis of fresh palm fruit bunches and medical waste plastic bottles using a batch pyrolyzer integrated with a downdraft gasifier was evaluated for sustainable electricity generation. Increasing the plastic fraction enhanced the gas heating value (41.43–55.53 MJ/Nm 3 ) but decreased gas yield from 22.7 % to 9.0 %. Electrical efficiency was calculated based on the ratio of output power to syngas energy content, achieving 8.96–9.01 %. Engine tests showed a reduction in CO emissions (30,149–17,419 ppm) and comparable NO x levels to gasoline combustion. These results demonstrate the co-pyrolysis gas's potential as a renewable fuel for decentralized power.

COSPAS-SArSAT has currently completed the design of a new generation distress beacon systems, namely the second-generation distress beacon system. The second-generation distress beacon adopts dSSS-OQPSK as its basic signal modulation mode, while adopting a new signal detail structure. This paper provides a solution for the hardware implementation of the second-generation COSPAS-SArSAT distress beacon on Software-defined radio (Sdr). Firstly, the baseband signal that meets the definition format of the second-generation beacon standard was generated, and then the second-generation beacon was transmitted through the Universal Software radio Peripheral (USrP). By comparing with specific requirements of the second-generation distress beacon standard, the second-generation beacon generated by this paper can meet the requirements of the second-generation COSPAS-SArSAT distress beacon standard, and the method proposed in this paper has the advantages of flexibility and higher signal reconfigurability. © 2023 IEEE.

In response to the complex seepage mechanism of unconventional oil and gas reservoirs, large-scale volume fracturing of multi-segment and multi-cluster horizontal wells, and differences in oil and gas pressure and saturation properties, which result in uneven distribution of eigenvalues, large value of conditions, and slow solving speed of nonlinear equation matrix, a multi-stage decoupling preconditioning solution technology was carried out on the Jacobian coefficient matrix of the oil and gas numerical discrete equation based on the implicit pressure explicit saturation method (IMPES) processing idea. Multi-grid method (AMG) + block based incomplete LU decomposition method (BILU0) are used to preprocess the Jacobian coefficient matrix in multiple stages, and the block based generalized minimum residual method (BGMrES) is used to solve the preconditioned nonlinear algebraic equations. The calculation result proves that compared with other single processing methods, this method effectively reduces the number of iterations for solving discrete equations while ensuring calculation accuracy, improves calculation speed, and has important application value for rapid formulation and decision-making optimization of oil and gas field development plans. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

With the gradual application of knowledge atlas technology in oil and gas exploration and development fields such as intelligent evaluation of oil and gas reservoir and intelligent identification of oil and gas reservoir through logging, the application of knowledge Atlas in oil and gas industry has attracted more and more attention. In view of the problem of knowledge expression and application in E&P sector field, a professional word bank of E&P was established based on web crawler technology, a feature corpus of E&P field was established by extracting E&P sector related achievement documents and literature data, and the principle of E&P knowledge graph ontology construction was formulated and the construction process was defined. The multistage classification system of oil and gas exploration and development knowledge atlas ontology is described and constructed from multiple dimensions such as sector, object and feature, and the knowledge atlas ontology model of oil and gas exploration and development sector domain is formed, which lays a foundation for the in-depth application of knowledge atlas technology in petroleum exploration and development. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

In this study, the influence of poly-Si surface wettability on the removal of defects from CMP (Chemical Mechanical Planarization) process was investigated. The poly-Si surface is hydrophobic in nature which attracts the hydrophobic organic residues including the pad debris, slurry additives and so on. Therefore, the adhesion between organics and poly-Si surface is dominant among the defects in poly-Si polishing. For this reason, the control of poly-Si surface wettability is a key for the reduction of CMP residues. The alkaline solution which contains the hydrophilic polymer was supplied to change the surface properties in the final polishing step. The hydrophilic layer acts as a sacrificial layer for the removal of organics. The following in-situ SC-1 cleaning removes not only the hydrophilic layer but also the organics on its surface. In case of abrasive particles in slurry, they were removed by the repulsive force between the same charged poly-Si surface and particles in SC-1 process. Furthermore, the prevention of abrasive particles in the main photo keys was also confirmed. This indicates the hydrophilic polymer in poly-Si CMP process decreases the defects which can skip the cleaning process. This enables the simplification of overall semiconductor process and reduction of CoO (Cost of Ownership). © VdE VErLAG GMBH Berlin Offenbach
