Solid phase extraction is a common procedure to separate the desired analytes from a complex sample matrix (sample cleanup). This multi-step procedure is often performed in a manual way with sequential sample processing. An automation will increase the sample throughput by parallel processing of multiple samples. In highly regulated areas, established and validated standard operating procedures must not be changed. The automation of laboratory processes often requires a process adaption, which results in differences to the manual procedure and many processes are still performed manually. Flexible automation systems are needed to perform a sample preparation process identical to the manual procedure. Dual-arm robots are a promising solution due to their human-like structure. A positive pressure unit for automated solid-phase extraction was integrated (hardware and software) into a dual-arm robotic system. The system allows automated compound-oriented measurement processes identical to the manual procedure. The graphical user interface enables the process generation and adaption by laboratory staff without programming knowledge or direct robot teaching. A practical application was realized for determination of benzoic acids in water using gas chromatography mass spectrometry. The entire process involves the solid phase extraction followed by a sample derivatization, the transfer of the samples into the autosampler of the measuring device and the measurement in a fully automated process using a dual-arm robot.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"11 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":"91129110","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}

Facing the challenge of its changing working conditions, intelligent monitoring models that are built upon constant working conditions are not qualified for this task. To solve this problem, a syncretic self-regression variational auto-encoder (SSR-VAE) model is proposed to realize the parallel training of distribution learning and regression learning for machine anomaly detection. Among them, self-regression learning plays an auxiliary role in distribution learning. Furthermore, multi-sensor information fusion at the decision level is implemented to improve the robustness of the proposed model.

This enhanced circuit also provides added advantages like immune to drifts of the capacitor and the mismatch between the high and low-level voltages of the components used in the scheme.

The basic principle of the simulated calibration method and the main design ideas of the simulated calibration instrument are analyzed. A 77GHz MMW radar sample is chosen for speed and range simulated calibration, and the uncertainty of the calibration results is analyzed and evaluated from the aspects of measurement repeatability, MMW radar resolution and accuracy of the simulated calibration instrument.

Essential basic functionalities are the synchronous switching of the antenna elements at both link ends and an integrated automatic gain control (AGC) at the receiver. To meet the high timing requirements in the switched MIMO setup, an FPGA-based AGC is introduced. The detector of the AGC is based on a sample-by-sample calculation of the average and maximum of the I/Q samples within a sliding window. The used SDR hardware allows a minimum AGC update interval of approx. 14 µs and a timing accuracy of the antenna switching of 5 ns. Our setup demonstrates the applicability of state-of-the-art SDRs as a sounding system for continuous acquisition of the time-variant, directional mobile radio channel.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"1 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":"75564703","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}

Windowing techniques improve the resolution of the Power Spectrum estimation by reducing the sampling gap caused by the periodic extension of the Fourier Series. However, it adds a time domain non-stationarity which affects the Surrogate Analysis. This effect is particularly problematic for short lowpass signals. Applying the same window to the surrogate data allows having the same non-stationarity. The method is tested on order 1 autoregressive process null hypothesis by Monte Carlo simulations. Previous methods were not able to yield good performances for left-sided and right-sided tests at the same time, even less with bilateral tests. It is shown that the new method is conservative for unilateral tests as well as bilateral tests.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"11 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":"73817161","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}
