Published: March 2023

Abstract
Fiber Optic Displacement Sensor (FODS) categorized as one of the optical sensor based reflective intensity modulation. An intensity based sensor have been widely used in detecting various substances due to their simplicity structures. Generally for sensing principle, a pair of fiber is used to construct FODS which one of optical fiber is the transmitting fiber and another one is receiving fiber. The objective of this current work is to introduce FODS to evaluate the optical response in terms of voltage reading at different concentration of hydrogen peroxide in two different types of milk. A real-time measurement, low cost, stability, high sensitivity and simplicity of design promote a well-developed sensor in providing useful parameters in detecting hydrogen peroxide in milk. Hydrogen peroxide is an adulterated agent added in milk that can harm the consumers. Transmitive optical sensor as a function of displacement technique was developed to study the hydrogen peroxide concentrations in the range of 0 %-10 % as consuming more than 3-10 % of hydrogen peroxide can cause mild allergies reactions, stomach upset and vomiting. The output from the receiving fiber in this designated system was measured in terms of voltage reading through multimeter. The sensor shows outstanding performances of delivering 0.0007 V/% sensitivity for low fat milk and with linearity of >98 %. Whereas, the sensitivity achieved for full cream milk was 0.0005 V/% with a good linearity >97 %. The simplicity and credibility of this system offer a good opportunity in this project and also foods industry applications.

Abstract
Nickel nanoparticles exhibit superior ferromagnetic properties. This has attracted great interest due to its significant potential applications in various fields. The properties of nanomaterials are greatly affected by the environmental conditions during the synthetization process. In this work, nickel nanoparticles were synthesized by pulsed laser ablation in distilled water, ethylene glycol, chitosan, gum Arabic and walnut oil. For all samples, the ablated process was conducted for 5 minutes. The optical properties of colloidal nanoparticles were investigated by UV-Visible spectroscopy and Fourier Transform Infrared (FT-IR) spectrometer. Data from experimental works released that walnut oil has highest absorbance intensity which might be contributed to the existence of alkene functional group.

Published: March 2023

Abstract
This study investigates the catalytic activity of Ru/Mn/Ce-Al2O3 in eliminating HCN via dry reforming CH4 with CO2 in the packed-bed dielectric barrier discharge non-thermal plasma (DBD NTP). A packed bed DBD configuration method was carried out in the non-thermal plasma with Ru/Mn/Ce-Al2O3 catalyst, whereby BaTiO3 beads was the dielectric medium. The carrier gas for dry methane reforming was N2, the peak-to-peak voltage was 24 kV and the total flow rate was 100 sccm with a ratio of 5:5:90 (CH4:CO2:N2), respectively. Gaseous products and by-products were analysed by Fourier transform infra-red (FTIR) spectroscopy. Experimental results revealed that Ru/Mn/Ce-Al2O3 catalyst could eliminate HCN at approximately 82% and had a low selectivity in decomposing NH3. Besides, the conversion of CH4 achieved was approximately 68%.

decays are characterized by the emission from the kaon of either a real or virtual photon, respectively. The nonperturbative interaction of the photon with the internal hadronic structure of the decaying meson is described by suitable form factors. With the huge improvement in the precision of lattice QCD results, increasingly QED corrections are included and in this work we review the latest lattice QCD predictions for the form factors and/or branching ratios of those processes. Moreover, we compare those predictions with existing experimental results. The comparison provides some interesting puzzles suggesting possible signs of new physics and motivates future improvements on both the theoretical and experimental determinations of the relevant form factors.

Published: March 2023

Abstract
The observation of neutrino oscillations is firm evidence of non-zero neutrino mass. Neutrino mass and mixing have been studied by neutrino oscillation experiments so far. One of the remaining questions is whether neutrinos violate CP symmetry. Exploring new CP violation is also a subject of kaon physics. There are other common physics topics between neutrino and kaon experiments. In this talk, recent progress and future prospects of neutrino experiments for topics related to kaon physics will be discussed.

A three-dimensional sampling electromagnetic calorimeter for the KOTO II experiment with the future extension of J-PARC Hadron Facility
Authors: Kim YoungJun 
Published: March 2023

Abstract
We present a Geant4-based simulation study of the three-dimensional (3D) electromagnetic sampling calorimeter (ECAL). The 3D ECAL model consists of alternating layers of plastic scintillator and lead sheets where the scintillators are divided into strips and alternatively oriented in vertical and horizontal directions. With the energy deposits in the individual strips as a result of Geant4 simulation, the incidence angle of photons is reconstructed using the XGBoost with boosted decision trees. We report on the performance of the directional measurement which depends on both detector configuration and the maturity of the training.

Research on Metal Target Classification Method Based on Multi-Frequency Electromagnetic Induction
Authors: Wang Zhan , Jiang HeJun , Luo ZhaoPeng , Zheng FangFu , Xiao KeZhen , Qu ShiHua , Wu MeiWu 
Published: March 2023

Abstract
The traditional single-frequency metal mine detector is limited by the single-frequency component, which is difficult to meet the requirements of high-accuracy detection of multiple types of mine targets. The modulation square wave is used to transmit the multi-frequency signal based on the multi-frequency electromagnetic induction technology. The phase-locked amplifier is used to extract the signal feature of each frequency component. The naive bayesian algorithm is used to classify metal targets according to the extracted feature vectors. This method can effectively improve target classification accuracy compared with single-frequency metal mine detectors.
Infrared small target detection based on YOLO v4
Authors: Lin Zhongwu , Huang Min , Zhou Qinghui 
Published: March 2023

Abstract
Infrared imaging is highly stealthy, reconnaissance and resistant to interference and currently has numerous practical applications in many fields, particularly in the military and civilian sectors. Infrared images are prone to drowning small targets in the background due to the lack of textural detail and the presence of a large amount of background noise. Small target detection on infrared images is therefore very challenging, and traditional model-driven algorithms are no longer very applicable in the face of complex and variable infrared images, so more and more people are turning to deep learning methods. We have designed a target detection network based on YOLO v4 with the following improvements, using GhostNet as the backbone network used to extract features and achieving a lighter weighting of the backbone network. We added a coordinate attention mechanism to the design of the feature aggregation process of the network, so that the network senses the spatial location relationship while the channel is attended to, enhancing the network’s ability to localise targets. To further reduce the number of network parameters, by using depthwise separable convolution in the feature aggregation part and detection part instead of normal convolution. Our experimental comparisons on the dataset NUAA-SISRT show that Ghost-CA-YOLO v4 is the leader in terms of detection accuracy and parameter efficiency. The model has an mAP metric of 73.31% and an F1 value of 0.78. The number of parameters is 44.8M, which is 1/5 of that of YOLO v4.

Authors: Liu Jianli , Jin Xin , Han Xuefeng 
Published: March 2023

Abstract
In this paper, taking a benzene transport vehicle as an example, a cylindrical tank model is established according to the relevant standards, and the electrostatic potential distribution in the tank of dangerous chemicals is numerically simulated. The potential distribution in the tank is calculated by numerical calculation software, and the three-dimensional distribution map of the electrostatic potential of the medium in the tank is obtained. The general rules between the electrostatic potential distribution in the tank of a hazardous chemical tanker and the filling rate, the number of Anti-wave plates, and the two phases of gas and liquid were analyzed. The relationship between volume, Anti-wave plate area, and electrostatic potential was further analyzed by studying the relationship between electrostatic potential and medium parameters. A model of an elliptical cylindrical tank was also constructed, and corresponding anti-static measures were proposed.
OpenCV-based SF6 density controller dial pointer angle recognition
Authors: Yu Zhangsi , Ning Zhang , Yang Houcheng 
Published: March 2023

Abstract
To solve the problems of the low efficiency and poor accuracy of the manual detection in the factory inspection of the SF6 density controller, this paper proposes an SF6 density controller dial pointer angle identification method. First, the image of the dial pointer at a specific position is acquired according to the working characteristics of the SF6 density controller. The center and radius of the contour circle inside the scale line in the dial are extracted using the Hoff gradient method and the image is coordinate transformed using this parameter. Then the coordinate-transformed image is pre-processed. And finally, the threshold of the image after pre-processing is traversed and the length is used to characterize the pointer angle through the correspondence between the scale line and the angle. The angle of the pointer is characterized by the correspondence between the scale and the angle using the length. This paper uses Python and OpenCV vision library to complete the algorithm and through experiments, the algorithm can achieve high precision pointer angle recognition.
A method for simultaneously calibrating projectors and correcting nonlinearities
Authors: Huang Geng , Lv CiXing 
Published: March 2023

Abstract
In FPP, projector nonlinearity is a significant factor affecting calibration accuracy and the reconstruction effect. Existing techniques frequently separate system calibration from nonlinearity correction, and the majority of these correction techniques necessitate the acquisition of additional images, making the process laborious. In this study, we provide a technique for solving both the nonlinear error function and the projector parameters at the same time. The parameters of the nonlinear error function are first estimated using a theoretical calculation of the phase error due to nonlinearity, based on the distribution relationship between the reprojection error and the phase of the characteristic points. The resulting nonlinear error function is then used to correct for the wrapped phase. It was shown that the projector reprojection error was decreased by 14.7 percent (RMS) and the object reconstruction quality was enhanced after two iterations.
Improvement in Connecting the Structure of Spherical Crown Middle Head
Authors: Luo Yu , Wang Zhuobin , Wang Qiang , Mao Haofei , Hong Qingbin , Li Liang 
Published: March 2023

Abstract
In a pressure vessel, a spherical crown head can be used as an end head or a middle head. Without a common tangent to connect the surfaces of the spherical shell and cylindrical shell, the connection between the spherical crown head and shell produces stresses and deformation at the edge of the connection, so the head and shell in use need to be stiffened and a stiffening section needs to be arranged. With a stiffening section, stainless steel equipment includes more welding beads and looks less aesthetically attractive. If the shell is stiffened as a whole, the thickness of the shell needs to be increased to the thickness of the stiffening section, which is closely related to the radius of curvature Ri of the spherical crown head. Therefore, in design, the optimization of the ratio of the radius of curvature of the head to the internal diameter Di of the shell must be considered, to obtain the spherical crown head and stiffening section with the minimum thickness. However, in most cases, the thickness obtained may not be the most economical, because the head may be non-standard, and is usually formed by stamping, requiring a costly die. Furthermore, it is permissible for all thicknesses of the shell to be increased to obtain the entire shell instead of a pieced-together shell, and such design can cause too great an allowance of strength, merely increasing the costs of manufacturing. The design of dual-cavity-tank equipment used for irrigation by a company requires the use of a spherical crown head as the middle head. In the design, the challenge confronted by the authors is to ensure an attractive appearance, as well as an economical and reasonable cost. In the design, the internal volume was slightly reduced, the way of connecting the shell and the stiffening section was changed, and the optimal ratio of the radius of curvature of the head to the internal diameter of the shell was selected, to obtain the most reasonable thicknesses of spherical crown head and stiffening section. Thus, the actual difficulties encountered have been resolved.

Published: March 2023

Abstract
Aiming at the problems of low cleaning efficiency, damaged nozzle, and high safety hazard in the traditional cleaning method of the fused deposition modeling (FDM) equipment nozzle, an environmentally friendly nozzle cleaning system was designed by using the chemical solvent and ultrasonic cleaning technology. The modular design of the nozzle clamping module can improve the nozzle loading efficiency and cleaning efficiency. The cleaning liquid circulation device makes the cleaning process automated under the coordination of the control module, which effectively reduces the safety hazards of the cleaning process. A thermal drying device is mainly used to speed up the drying rate of the nozzle. An exhaust gas purification device is used to absorb the volatile chemicals in the cleaning process and reduce pollution in the working environment.
