One of the critical aspects of these systems are the requirement to follow the crop rows without damaging the plants or the dam. In this paper, a system was developed which enables a semi-autonomous flight by means of crop row detection in organic agriculture. The system consists of a Raspberry Pi microcontroller with a camera and uses a number of image processing methods to detect plant rows. The evaluation of images of different crop row fields and of crop row models showed that all different plant rows were reliably detected. A runtime evaluation showed that the computing power of the microcontroller for the application is limited. Optimizations such as reducing the image size and adapting calculation-intensive methods resulted in a frame rate of 8 to 12 FPS. This processing time is sufficient for a slow UAV flight.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125331440","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 relation-ships between SVD-based denoising and other advanced signal processing methods are very significant and can help speed up the development of SVD-based denoising methods. There is limited prior work into the sparse and low-rank meaning of SVD-based denoising. In this paper, we build the relationships among SVD-based denoising, sparse l0-norm minimization, sparse weighted l1-norm minimization, and weighted low-rank models, when the dictionary is designed by left and right singular matrices in sparse minimization. Using the derived conclusion, we establish weighted soft singular value decomposition (WSSVD) for vibration signal denoising. Finally, we perform one experimental study to verify the effectiveness of WSSVD considering impulse interference and amplitude fidelity.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125349930","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}

A detailed theoretical model was developed to calculate the spectral reflectivity of the micro-devices when they are placed at the end of the measuring arm of a Michelson scheme. Using the readout radiation provided by a broadband light source with a flat emission spectrum centered at 1.55 µm and a 2x1 fiberoptic coupler on the common input-output optical path, experimental results were found in good agreement with the expected theoretical behavior. The optical resonances, corresponding to reflectivity minima, of these simple optical resonators are clearly detected by monitoring the positions of steep phase jumps on the interferometric signal recorded as a function of the wavelength.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114935104","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}

Composite films are prepared by dispersing 20, 30, 40, and 50 wt% of BaTiO3 in cross-linked PDMS matrix. Corona poling of the films is performed to improve the piezoelectric properties of the films. Piezoelectric properties of the films are studied by measuring the charge developed across the thickness of the film under a compressive force. A 50 wt% poled BaTiO3-PDMS film has shown a piezoelectric charge constant of 178 pC/N and achieves a dielectric constant of 4.59. Tensile tests indicate that these films are very soft and flexible with low Young’s modulus. A 50 wt % poled BaTiO3-PDMS film film has shown a Young’s modulus 3.92 Mpa. The film generates charge across the film proportional to the finger pressure applied on them. Thus it demonstrates effectiveness for tactile sensing. As a tactile sensor a 50 wt% poled film shows a sensitivity of 38.34 kPa−1. High charge response for tiny forces makes the composite a good candidate for tactile sensing applications such as robotic skin and touch pads.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116537368","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}

Different with conventional clock sampling architecture, where a jittery signal is sampled by a regular clock signal, we use the jittery clock signal generated by Galois ring oscillator (GARO) to sample the regular clocks that are generated by normal phase locking loop (PLL) of FPGA. This sampling architecture is hereafter called as event sampling architecture. To guarantee every sampled bit has maximum entropy value, the regular clock signal is routed into a tapped delay line (TDL) forming a multi-phase clock signal before it is sampled for exclusive OR (XOR) operation. A prototype of such a TRNG is implemented in a Xilinx Artix-7 FPGA. The generation rate, the randomness of the bit sequence, as well as its robustness to ambient temperature are evaluated in detail. Comparing with the similar TRNG implementation but using the clock sampling architecture, the proposed TRNG can increase the generation bit rate by 1.33 times, while the logic resource consumption is greatly reduced (saving 33% of the look up tables and 81% of the flip-flops). A comparison with various prior TRNG designs in terms of category, logic resource usage, and generation rate demonstrate that the proposed method has the advantage of high rate of generation rate to logic resources. Therefore, it is more suitable for the generation of high-speed true random numbers, which is especially important for applications in current high-speed quantum key distribution systems.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"BME-22 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114125297","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 important to verify these devices, which are located in different units in hospitals, without taking a long time because of daily excessive workload. For this purpose, it has been aimed to realize the power verification without causing excessive workload with the ultrasonic power meter device and software developed in our laboratory.The developed device produces a voltage value corresponding to the radiation force generated by the reference masses. Ultrasonic power value is calculated using this voltage value. In order to shorten the verification process, after the verification of certain points instead of the entire measurement region, a curve equation is found with the linear regression method. Ultrasonic power values other than points corresponding to reference masses are verified using this equation. While obtaining the equation, the standard deviation values are calculated according to the results of the measurements and the upper and lower limits are determined in the 2-sigma range by using 2 times the standard deviation. For power measurements made after the equation is obtained, measurement values outside these limits are not included in the calculation. In other words, the reliability of the measurement results is 95%. In the ultrasonic power calculation method presented in this article, it is concluded that the power values obtained by the linear regression method with the reference mass values and the ultrasonic power meter and software accurately estimate the measurement within 5% error limits.","PeriodicalId":227967,"journal":{"name":"2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114423406","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}
