Currently, fractional operations are widely used in many fields such as system control, chaotic systems, and fault detection. In order to simplify the implementation of FPGA-based fractional operations, this paper proposes a method of implementing a digital oscilloscope based on FPGA and using logic resources to implement the fractional arithmetic defined by Grünwald-Letnikov(G-L). In addition, the number of calculation points for fractional operations is fixed and the sampling interval is variable. The simulation and hardware implementation results of fractional order operation of some conventional periodic signals with some selected fractional orders have been presented. The testbech results show that the use of four parallel calculations can increase the calculation speed by about 3.75 times. Sine wave is used to verify the calculation results of some fractional parameters. Experimental results show that high-precision floating-point calculation and large dynamic range measurement technology can improve the accuracy of fractional calculation. The phase accuracy of fractional arithmetic is improved by using waveform synchronization display technology of digital oscilloscope. Additionally, the consistency of simulation and experimental results proves the applicability of fractional order operation in digital oscilloscope.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"90 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79586396","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}

However, early nutrition interventions to establish such norms are uncommon owing to the various inefficiencies associated with current methods of measuring childhood nutrition. Here, we present an IoT measuring device, called the SensiTray, which accurately tracks mealtime intake in a child-friendly and cost-effective fashion. Principal technologies underlying the SensiTray (including mass-sensing technologies, microcontrollers) are identified and analyzed, along with other design choices. Operation of the SensiTray is explained with special attention given to SensiTray software peripherals and algorithms. Preliminary testing consisted of static and dynamic simulations (i.e. food weights constant and changing), with the SensiTray demonstrating a high degree of accuracy in both formats. Future development of the SensiTray may focus on design iteration, additional testing, and experimentation with various mealtime data visualizations to precipitate positive dietary changes.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"71 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83339321","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}

The rapid development of on-orbit spacecraft generates a large amount of telemetry data with high dimensionality and complex correlation between variables, which brings great challenges for current and future ground management and operation for these spacecrafts. As a result, its anomaly detection becomes an essential solution for enhancing the operation safely and reliably and realizing intelligent maintenance. The above issues make it a hot spot research topic for realization of high detection rate, low false detection rate, and strong interpretability of anomaly detection of telemetry data. In further, timely detection of abnormalities can reduce spacecraft unexpected accidents. Recently, Temporal Convolution Network (TCN) has arisen much attention for telemetry time series data modeling by its good parallel processing ability and temporal characterization. Thus, this paper proposes an anomaly detection model for spacecraft telemetry data based on TCN time series prediction. Firstly, TCN algorithm is used to extract features of telemetry data and make a prediction. Then, the potential anomalies are determined by the static threshold judgement method. Actual satellite telemetry data are used to implement performance evaluation and comparison. The proposed method is compared with Long Short Term Memory (LSTM) algorithm which is also a widely utilized algorithm in recent time series analysis. Four metrics are adopted for the experiments: the detection accuracy, detection rate, false detection rate and model inference time. TCN achieves high accuracy, high detection rate and low false detection rate. In addition, TCN save much more model inference time than LSTM with long timestep. Generally, TCN is superior to LSTM on operating efficiency.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"14 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84616956","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 article, we investigate the robustness of such a measuring system to the considerable inter- and intra-variability in blood flow and hematocrit that characterize the ECC treatments. The obtained results demonstrate that, although during the tests the flow and hematocrit values were significantly varied $(pmathbf{CO}_{2}$ from $approx 20$ mmHg, to $approx 110$ mmHg; hematocrit from 32%, to 40%; flow from 250 ml/min, to 400 ml/min), the measuring system continued to guarantee a measurement error in the range [-4, 4] mmHg, thus fully complying with the metrological requirements for the in-line and real-time monitoring of blood$-pmathbf{CO}_{2}$ during ECC.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"146 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75369818","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}

The experimental pipe diameter is 50 mm, the ranges of gas and liquid superficial velocity are 15–30 m/s and 0.015-0.1 m/s, respectively. The working condition is ambient temperature, and the pressure $P$ is 0.1-0.7 MPa. Besides, the liquid film thickness at different circumferential positions is obtained and analyzed quantitatively under 53 working conditions. The experimental results are compared with the existing correlation, and considering the influence of system pressure, a new prediction correlation for CLFT is established. The relative error between the experimental results and the new correlation is within ±25%, which verifies the applicability of the new correlation.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"18 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74978312","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}

It is small in size and simple in design and can be prepared at low cost. The sensor and the associated electronic circuit may be prepared in compact form using integration techniques. The structure of the sensor is simple having four conductive brass electrodes, arranged in the form of a concentric cylinder, with narrow gaps among them. The structure was designed using ANSYS software, then simulated using ANSYS MAXWELL 3D software by varying the geometric dimensions and liquid conductivity. Experimental results, on a compact proto-type model, were also included. It can differentiate between pure and adulterated water with significant resolutions. The sensor was fabricated and tested in the laboratory environment, with different bottled water samples having different total dissolved solids (TDS) values, available in the market. Liquid samples were prepared carefully to ensure the reliability of the results.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"65 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74829991","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}
