The research results are helpful to the optimization design of LPFG sensor based on strength detection. By applying the four-layer model to the analysis of the sensor, it is found that the grating period has an important influence on the transmission spectrum coupled at the turning point of detuning. When the cladding mode and the core mode of the grating are coupled at the turning point of detuning, the peak loss of transmission spectrum varies linearly with the grating period in a certain grating period range. Within this range, the shorter the grating period, the higher the peak loss, while the resonant wavelength remains basically unchanged. The peak loss of transmission spectrum is related to the linear range and slope of grating period. The higher the environmental refractive index, the narrower the range of the linear segment and the smaller the slope. Adopting this characteristic of LPFG, temperature and stress sensors based on intensity measurement can be fabricated.","PeriodicalId":354742,"journal":{"name":"2020 4th Annual International Conference on Data Science and Business Analytics (ICDSBA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134360963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study draws on the global and local advantages of using a convolution dictionary, and proposes an image-fusion technology based on convolution dictionary learning for use on medical images of the brain. A fast Fourier transform is applied to the source image, and the image is decomposed into low-frequency and high-frequency sub-bands; then, suitable fusion rules are used for the low-frequency and high-frequency sub-bands respectively; finally, the inverse fast Fourier transform is used to obtain the fused image. Experimental results show that the proposed fusion technology is superior to the comparison algorithm in objective performance indicators. Moreover, subjective evaluation shows that the texture of the image obtained by the proposed fusion technology is more detailed and more informative.","PeriodicalId":354742,"journal":{"name":"2020 4th Annual International Conference on Data Science and Business Analytics (ICDSBA)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114654362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we propose a new device named tangible interactive projector to effectively enable projection touch tracking and spatial augmented reality, in which we use object detection, instance segmentation and keypoints detection to improve the efficiency of touch detection and reduce the probability of misrecognition. We implement the spatial augmented reality method with the combination of the projection unit, computing unit, and perception unit. The perception unit consists of a high definition camera and an infrared camera, providing more modal data for touch recognition, which also makes it possible to display the projection adaptively according to the type and shape of the object in the field view using the bounding box output by object detection.

Through the analysis of the simulation results of the rigid body model and rigid flexible coupling model, it can be seen that the crank-shaft has a small deformation under the force of piston force. Comparing the simulation results of rigid flexible coupling model with crack and without crack when crankshaft rotates clockwise, it is found that the existence of crack increases the deformation of crankshaft. By comparing the simulation results of the rigid flexible coupling model with and without crack when the crankshaft rotates counterclockwise, the influence of crankshaft steering on the deformation of cracked crankshaft is found. The stability of the system is discussed by using phase diagram and Lyapunov exponent. The results show that the motion of the system is chaotic when the crankshaft with cracks rotates in reverse direction.","PeriodicalId":354742,"journal":{"name":"2020 4th Annual International Conference on Data Science and Business Analytics (ICDSBA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127432038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
