In the process of infusion, newborns, children, adults and the elderly have different requirements for infusion speed. Patients with poor metabolism of cardiopulmonary function and renal function need special attention, because infusion speed is not only related to the patient's heart load capacity, but also affects the efficacy of drugs, and even some patients will have drug reactions due to too fast infusion dripping speed. Besides, some problems such as untimely dosing, manual control of dripping speed and inconvenient call for medical staff exist in the process of infusion. Aiming at the above problems, in this paper, a remote medical monitoring system based on STC89C52 is proposed and designed. In the ward, sensors are used to detect the liquid level and dripping speed of liquid during infusion. Through ZigBee CC2530 wireless transmission, the infusion information is sent to the nurse end to realize remote monitoring. If there is too little medicine left or the infusion dripping speed is too fast during infusion, the alarm occurred in time, and meanwhile the infusion dripping speed can be controlled. After tested, the system runs stably, and the required functions such as real-time liquid level monitoring, real-time dripping speed monitoring, intelligent dripping speed adjustment and automatic alarm can be realized, which indicates that by using this system, the problems of the traditional infusion system can be solved, which has a strong practical value.","PeriodicalId":178822,"journal":{"name":"Proceedings of the 4th International Conference on Computer Science and Application Engineering","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115682173","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}

Unattended and remote control are gradually adopted during testing and launching. We propose the highly reliable redundancy scheme of remote automatic control. Architecture and the corresponding strategy are designed for the hierarchical redundant control of the launch site. The remote host computers of the architecture are industrial control computers configured in parallel redundancy. The slave computers are redundant programmable logic controllers (PLC). The industrial control network of the architecture consists of a double redundant backup network, which set up a double set of the emergency backup circuit. PLCs and industrial control computers communicate with the industrial Ethernet of high-speed ring optical fiber. Distributed control equipment such as field slave computers and variable-frequency drives communicate and transmit data by means of the industrial Ethernet. Relay contacts are designed as a redundant loop with two points and two lines. The scheme designs and discusses the policies and work patterns of intelligent autonomous redundancy. The paper also presents the key points of intelligent redundancy solution and reliability enhancement. The proposed intelligent redundancy scheme has been applied in China space launch sites.","PeriodicalId":178822,"journal":{"name":"Proceedings of the 4th International Conference on Computer Science and Application Engineering","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130842056","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}

Methods. Models for IHM prediction were built following the analysis of 866 electronic case histories based on the analysis of CAD patients, revascularized with the CABG operation. The patient cohort consisted of two groups. The first included 35 (4%) patients who died within the first 30 days after CABG, the second - 831 (96%) patients with a favorable operation outcome. We analyzed 99 factors, including the results of clinical, laboratory and instrumental studies obtained before CABG. For feature compilation, classical filtering and model selection methods were used (wrapper method). The primary drawback to applying a classical approach was the unbalanced sample as one cohort only consisted of 4% of subjects. In that case, it was not possible to apply the cross-validation procedure with three types of samples, standard quality metrics and multi-category factors. Results. Features searching approach using the multi-stage selection procedure, which combined the validation of predefined predictors, filtering methods and multifactor model development based on logistic regression, random forest (RF) and artificial neural networks (ANNs) was proposed. The models' accuracy was evaluated by a combined quality metric. RF and ANNs based models allowed not only to build more accurate forecasting tools, but also assisted in verifying five additional IHM predictors.","PeriodicalId":178822,"journal":{"name":"Proceedings of the 4th International Conference on Computer Science and Application Engineering","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122146392","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}

To the best of our knowledge, when forward operators in TensorFlow specifies a new device, the backward gradient operator in the same neural network cannot use the same device, which does not comply with rules about node device allocation in TensorFlow. Therefore, we propose an improved algorithm for node device allocation based on placement mechanism and an optimization algorithm for conv2d operator based on OpenCL. The proposed improved algorithm for node device allocation makes forward and backward operators based on FPGA accelerator satisfy the node and device allocation requirements for all TensorFlow operators, and the conv2d operator optimization algorithm based on OpenCL takes full advantage of the parallel computing advantages of FPGA. Finally, this paper uses the CNN LeNet5 model and the MNIST dataset to conduct corresponding experiments. Referring to conv2d operator, based on FPGA accelerator, we implement both the forward and backward operators involved in the first four layers of the model. The experimental results show that the accuracy of the three methods is above 98%. Compared with CPU and GPU, the accuracy difference is only about five thousandths. In addition, in the case of different batch sizes, we tested the runtime of conv2d operator in the first layer of this model. The results show that when the input batch size increased to 10000, the FPGA runs 9 times faster than the CPU. It proved that we proposed an optimization solution for TensorFlow to use FPGA operators for neural network calculations.","PeriodicalId":178822,"journal":{"name":"Proceedings of the 4th International Conference on Computer Science and Application Engineering","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128426354","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}
