Two proven designs of polarization mode convertor (PMC) were compared through simulation for a modified commercial 830 nm GaAs-AlGaAs structure. Structure type 1 used a deep-etched ridge waveguide, with a shallow-etched slot placed asymmetrically within the ridge. Structure type 2 also used a deep-etched ridge, but with sides of the ridge etched to different depths. Both structures support zero-order TE and TM modes, with the effective index difference between the modes determining the length of the PMC device. Although a range of dimensions and compositions was investigated, it was found the geometry of the waveguides did not significantly affect the effective index difference. The refractive index of the waveguide core was swept from 3.39 to 3.43, corresponding to Al contents from 0.45 to 0.3 respectively. In both structures, a higher index leads to the mode being concentrated in the core, which may lead to lower losses. As the structures give similar results, the main decider as to which one should be chosen should be the relative simplicity of fabrication.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117301563","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}

Cuboid ‘mesa’ devices constructed from this material are consequently a promising technology for coherent, continuouswave radiation in the ‘terahertz gap’ range, spanning from approximately 0.3-1.5 THz. A key issue for practical applications of such devices is their cryocooling requirements, and it is therefore highly desirable to optimize their performance at temperatures that can be achieved by nitrogen cryogenics. Here we report generation of 0.13 milliwatts of coherent emission power at 0.461 THz, at a bath temperature of 77.4 Kelvin. This was achieved by exciting the (3, 0) cavity mode of a stack containing 579 junctions, and with Tc of 86.5 Kelvin. In order to minimize selfheating, the THz source was mounted on a copper substrate using PbSn solder. We will discuss the choice of mesa dimensions and cavity mode, and implications for the design of devices which are intended to operate close to the material’s superconducting critical temperature.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129619416","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}

As a result, the proportion of elderly people is increasing worldwide. Consequently, Dementia and Parkinson’s disease are expected to rise, thereby increasing the risk of critical events such as falls for elderly people. This has prompted many researchers to develop a wide range of solutions for fall detection and prevention. However, these solutions are either inaccurate or impractical due to hardware complexity. In this paper, we have proposed a novel Random Neural Network (RNN) based fall detection scheme. Results obtained from the proposed RNN-based scheme are compared with traditional machine learning methods such as Support Vector Machine (SVM) and traditional Artificial Neural Network (ANN) etc. From the results, it is evident that the proposed scheme has a higher accuracy of 98%. Additionally, several other parameters such as precision, recall, specificity, and F-measure show that the proposed algorithm has better generalisation capabilities when compared with other traditional machine learning schemes. Furthermore, the proposed RNN is also compared with a recent scheme and the obtained results demonstrate the superiority of the proposed scheme.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130557555","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}

Many industries have been benefited from the sensor fusion such as robotic, agriculture, healthcare, autonomous vehicle, navigation and so on. In the smart antenna industry, the conventional beamforming is implemented in the costly field programmable grid array (FPGA) platform with the complex direction of arrival (DOA) algorithm. In this work, we are presenting a feasibility study on a lower cost alternative called sensor aided beamforming that make use of the raw data from the existing sensors in the vehicle, combined with some simple mathematically calculation to determine the beam angle of the mobile client and roadside infrastructure. We have presented a practical approach to study the sensor aided beamforming system in the real environment by simulating the beamforming parameters for a moving vehicle moves along the road that was pre-installed with roadside access points (AP). The result has proofed that the sensor aided method can be used to realize the beamforming in the smart antenna system, with the IoT sensors cost approximately less than U$20 compared with the FPGA price range of around U$200, the sensor aided beamforming will be a cheaper and affordable alternative to the conventional beamforming system that usually realized with the complex direction of arrival algorithm and higher cost.","PeriodicalId":163493,"journal":{"name":"2020 International Conference on UK-China Emerging Technologies (UCET)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129831458","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}
