Authors: Han Xuefeng , Xu Huan 
Published: December 2022

Abstract
In this paper, a stand density extraction method is proposed based on QuickBird high-resolution satellite image data of Baisha artificial forest farm in Minhou, Fujian. Firstly, through the analysis band canopy image of QuickBird panchromatic, it is known that there is a maximum reflectivity point in the canopy. Then, the vegetation-covered area was extracted by the normalized difference vegetation index ( NDVI ). The canopy image of the forest was extracted through the decision tree classification algorithm. The texture information and spectral information were comprehensively utilized to classify the images. Then, the number of stand trees was extracted by the maximum filtering method, and the stand density was calculated to produce the stand density map. The experiment verified that this method can meet the needs of a stand density survey.

Authors: Liao Yuanyuan , Yin Gang 
Published: December 2022

Abstract
In the field of weather forecasting, short-term precipitation forecast is still a global problem. The complicated mechanism of convective weather system, the medium and small scale weather system brings great difficulties to the forecast, which is difficult to detect, understand and forecast. The application of short-term precipitation forecast is still in the initial stage. At present, the optical flow method based on radar echo is widely used in short-term and imminent precipitation prediction, but the optical flow method has obvious limitations. In order to improve the forecast precision of short-term and imminent precipitation forecast model, this study introduces the method of depth learning to build the forecast model. The application of depth learning to short-term precipitation forecasting is still in its initial stage. We analyze the existing models may exist in the shortcomings of the proposed in-depth learning model combination of different ideas. By combining different network structures (such as CONVLSTM, CONVGRU, etc.), we can get a better combined forecasting model. It has certain application value.

Published: December 2022

Abstract
. Exoskeleton robots are developing rapidly in the field of industrial manufacturing and medical rehabilitation as an intelligent wearable power assist device, which can reduce the lifting burden and muscle fatigue. Existing upper limb passive exoskeleton robots still need to be improved for human-machine integration. In this paper, by establishing a human kinematic model and a lumbar spine motion model, the lifting assist is analyzed, and the design principle of human-machine integration is used to complete the passive upper limb. In structural design, the exoskeleton robot is divided into 4 structural modules, combined with the specific motion form of the spring energy storage module to complete the cam curve design, and the EMG test system is used to collect the surface EMG of the user without wearing and wearing the exoskeleton robot. According to the signal EMG data, the experiment shows that the amplitude of the muscle EMG signal in the wearing state is smaller than that of the non-wearing muscle EMG signal, and the amplitude of the muscle activation amplitude varies from 0 to 10%, which verifies the effectiveness of the upper limb passive exoskeleton.

Abstract
In recent years, with the rapid development of artificial intelligence, speech recognition has irreplaceable advantages in human-computer interaction. In human-computer interaction, we hope that speech recognition has the characteristics of fast recognition speed, high recognition accuracy, and strong flexibility. This paper develops a hardware accelerator based on a programmable gate array, in which the nucleic acid detection systems utilize voice to complete machine control. We use a traditional BP neural network to train the parameters of the speech recognition model, and it is successfully deployed on FPGA to realize speech recognition. The acceleration effect is significantly improved, realizing that the cycles used before acceleration are almost four times those used after acceleration.
ISAR Imaging Method for High-speed Maneuvering Target Based on MFT-UNET3+ Network
Authors: Li Wenzhe , Luo Ying , Wang Zhihao , Zhao Xiaochen , Li Yuan , Li Bo 
Published: December 2022

Abstract
When inverse synthetic aperture radar (ISAR) images a high-speed maneuvering target, the imaging results of traditional methods are blurred and defocused in the range and azimuth directions because of the high speed and acceleration of the target. The existing imaging methods of maneuvering targets have poor imaging effects or low efficiency, and can’t eliminate the migration through range cells (MTRC) of far points on the target. Given that the existing methods can’t meet the imaging requirements of high-speed maneuvering targets, a new method by combing the UNET3+ convolution neural network (CNN) to machting Fourier transform (MFT) imaging process is proposed in this paper. Overcoming the limitations of the existing imaging methods, the proposed method can realize fast and accurate imaging for high-speed maneuvering targets. Experiments show that the novel MFT-UNET3+ method can achieve a good focus even under the condition of a low signal-to-noise ratio and down-sampling.

Published: December 2022

Abstract
Crossing a horizontal nonlinear resonance is the approach that can be used to split a beam
in several beamlets with the goal to perform multi-turn extraction from a circular particle
accelerator. Such an approach has been successfully implemented in the CERN Proton Synchrotron and
is used routinely for the production of high-intensity proton beams for fixed-target physics at
the Super Proton Synchrotron. Recently, thanks to the deployment of diamond detectors, originally
installed to monitor the beam losses at extraction, it has been possible to measure the horizontal
beam emittance of the split beam just prior to extraction. This is the first time that an
emittance measurement is attempted for split beams, i.e. in a regime of highly nonlinear beam
dynamics. In this paper, the technique is presented and its application to the analysis of the
experimental data is presented and discussed in detail. This result is essential for the
performance assessment of the splitting process and for the design of further performance
improvements.

Published: December 2022

Abstract
Climate change occurs naturally and due to accelerated elements due to human activities, which result in deviations from the average climate trend (increasing or decreasing). This study was conducted to identify the effects of climate change on the precipitation characteristics in the Palu watershed (DAS). The climate change analysis method used is Mann-Kendall-Sens. The analysis of the nature of rain uses the standard deviation, which shifts the wet month from the wet month to the dry month using the Oldeman method. This study uses secondary data, namely rainfall data from 1985–2020, from five rainfall stations. The results of this study indicate climate change in the Palu watershed, which is characterised by a negative Z value (decreasing) in January and a positive Z value (increasing) in June. The results of the analysis of the nature of rain in January for the 1985-1995 period were normal (N), the 1996-2006 period was below normal (BN) and the 2007-2020 period was below normal (BN). In June, the 1985–1995 period was below normal (BN), the 1996–2006 period was normal (N), and the 2007–2020 period was normal (N).

Authors: Najib M , Mulyati A , Astha A M Y 
Published: December 2022

Abstract
Settlements are an artificial environment that is formed and is strongly influenced by the local socio-cultural and climate. To remain in the unit of the residential setting, the settler will make adjustments based on his needs in a settlement system. This research aims to develop a pattern of living space for people affected by the tsunami in a settlement system. The study used a qualitative phenomenological approach to examine the settlements and environment in Wani II Village directly affected by the earthquake and tsunami. The unit of analysis includes housing, community activities, and community behavior in land use. The research design looks at the overall location description, sees the relationship between systems, gives meaning to social settings, analyzes data in the field through interpersonal relationships, and combines respondent information. The inductive method is used to continuously analyze the study cases as a purposively selected objective sample. The residential environment unit in Wani II Village, Tanantovea District, Donggala Regency, forms a clustered (concentrated) pattern, oriented to the environmental center, public facilities, social facilities, and existing ecological facilities and infrastructure. The settlement pattern formed is influenced by; a) the existence of worship facilities (old mosque); port facilities (pier); and c) the existing design of environmental roads. The land-use patterns are influenced by; 1) social resilience and cohesion built through social sense; 2) mutual trust between settlers; and 3) respect for existing culture and values. Several residential units that functioned as places of business were repaired and rebuilt on the existing site. The informal sector business spaces utilize the remaining areas that are still permitted for development. Residual land formed between buildings and between buildings and environmental roads and land for housing sites that have collapsed due to the earthquake and tsunami is the most dominant living space used for various activities that can support the lives of settlers with or without government assistance. Research conclusions are ‘local theories’ or ‘substantive theories,’ which apply specifically to the research area and are provisional.

Published: December 2022

Abstract
The volume of mung bean cultivation and export is also increasing in Uzbekistan. In Uzbekistan, mung bean is mainly planted as a repeat crop after wheat in June-July, and harvested in autumn in October-November. This provides additional income for farms and improves soil fertility. There are methods of mowing, plucking and harvesting mung bean from 5-10 cm above the surface of the ground, and cutting mung bean from the roots 5-10 cm below the ground. Because this method gives a good result in harvesting mung bean, which grows along the cultivated land in Uzbekistan and when the grain is ripe, but the stalks are green. Research is currently underway to develop a harvester that implements this method and to adapt the Dominator-130 combine to threshing without breaking the mung bean.

Published: December 2022

Abstract
The effectiveness of the use of “direct” sowing in the cultivation of grain crops in the north-east of the Non-Chernozem zone of the Russian Federation has been revealed. Field experiments were carried out in 2019-2021 on medium loamy low-humus gray forest soils with a high content of mobile phosphorus and exchangeable potassium. The weather conditions during the years of the experiments differed both in terms of heat supply and the amount of precipitation. The objects of the study were: winter wheat of the Moskovskaya 39 variety, spring wheat – Arhat, malting barley – Elf, fodder barley – Pamyaty Rodinoy, corn for silage and grain hybrid NK Gitago. “Direct” sowing was carried out using the Primera DMC (Amazone) sowing complex with the simultaneous application of mineral fertilizers for the maximum planned yield of each crop. On average, the maximum (3.43 t/ha) grain yield when using “direct” sowing was formed when cultivating corn, and the minimum (1.86 t/ha) – malting barley. In the production of these crops, the highest (2.42) and the lowest (1.85) energy efficiency coefficient, respectively, was also revealed. An analysis of economic indicators testified to the expediency of using “direct” sowing in the cultivation of winter wheat, which was reflected in obtaining the maximum (73.3%) level of profitability. The minimum (31.5%) level of profitability was noted in the cultivation of malting barley, which is explained by the high degree of material and labor costs and its relatively low yield. The profitability of the production of other types of crop products was 1.18-1.94 times lower. In general, the agronomic, energy and economic assessment showed bright prospects for the cultivation of winter wheat and maize for grain using the “direct” seeding method after potatoes.
