Huang, Jian Song","doi":"10.1109/EExPolytech50912.2020.9244004","DOIUrl":"https://doi.org/10.1109/EExPolytech50912.2020.9244004","url":null,"abstract":"With the rapid development of the Internet of things (IoT), simultaneous access of the massive devices to the network becomes essential. The current multiple access scheme in 4G is a traditional grant-based scheme which needs permission to access the system. It will suffer from congestion and overloading as the number of device increases. Therefore, grant-free random access, where users do not need to access channel resource through four step handshake process, recently gained wide interest in 5G new radio. Moreover, non-orthogonal technology is an effective way to deal with frequent collisions in the grant-free scheme. In this paper, we propose a grant-free non-orthogonal random access (GF-NORA) scheme based on sparse on-off resource pattern. The on-off pattern enables users to occupy resource blocks continuously or discontinuously. And the sparsity of resource pattern is helpful to change the distribution of non-collision part’s ratio of signals. A variety of operating modes are supported because of the flexible use of resource patterns. The simulation results indicate that the proposed method can effectively change the distribution of non-collision part’s ratio of signals when adopting the single user detection. By selecting the appropriate coded-modulation scheme to recover messages from the non-collision part, the outage probability will be reduced compared with slotted ALOHA.","PeriodicalId":374410,"journal":{"name":"2020 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130510243","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}

Small deformations (in the micrometer region) need to be measured with high accuracy using a small footprint (about 1 cm or less) sensor. Unfortunately, high coil current (from several tens of kA and more) and corresponding electromagnetic field create strong interference that makes it nearly impossible to use many types of electronic sensors. Fiber optic deformation sensors are sensitive and not affected by electromagnetic fields and thus are a very attractive solution. Various measurement techniques and their benefits and limitations are discussed. An interferometer using a 3x3 coupler was built, calibrated and used in experiments. The results of experiments with a fiber optic interferometer and a copper coil with currents up to 25 kA are presented.","PeriodicalId":374410,"journal":{"name":"2020 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"82 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128157000","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}

Indocyanine green is used to measure liver function with plasma disappearance rate parameter. Dynamic measurement of dye concentration in human blood allows to calculate plasma disappearance rate. Thereby, our setup is intended to be applied for liver function assessment. In water solution indocyanine green has absorption peak on 790 nm.
