Fluorescently labelled phospholipids are promising matrix molecules for the sensing layer in chemical biosensor applications. However, their electrical properties in a well-ordered monolayer deposited on a conducting substrate have not been investigated. Here we combine the powerful methods of Scanning Kelvin Probe Microscopy with nanometer lateral resolution and Electrical Impedance Spectroscopy (EIS) to investigate these properties. For the EIS measurements we use the interdigitated gold electrodes of a Surface Acoustic Wave resonator to measure electrical properties parallel to the substrate, which is a novel approach. Molecules behave as dielectrics with resistance around 440 GΩ. Lower resistance is observed at the boundaries of the micrometer sized solid phase domains where the film is the liquid phase. On exposure to chloroform vapors over two orders decrease in resistance was observed which was completely reversible.
荧光标记磷脂是一种很有前途的用于化学生物传感器传感层的基质分子。然而,它们在导电衬底上有序单层中的电学性质尚未得到研究。在这里,我们将扫描开尔文探针显微镜与纳米横向分辨率和电阻抗光谱(EIS)相结合的强大方法来研究这些特性。对于EIS测量,我们使用表面声波谐振器的交错金电极来测量平行于衬底的电学特性,这是一种新颖的方法。分子表现为介电体,电阻约为440 GΩ。在微米大小的固相畴的边界处观察到较低的电阻,其中薄膜是液相。暴露于氯仿蒸气超过两个数量级的电阻下降被观察到,这是完全可逆的。

Features of assessing the condition of complex objects 评估复杂物体状态的特征

In practice, complex objects are characterized by several parameters that can be correlated. Such facilities include most of the facilities / subjects of diagnosis in medicine, ecology, biology, meteorology, climatology, in assessing the quality of raw materials, all types of fuels and others. Assessment of the state of complex objects is carried out by ensuring the maximum completeness of the information about the parameters of the studied object by measuring the parameters that correlate with the studied parameter. The degree of commonality of the processes of measurement and diagnosis in terms of information is significant, which leads to the need for their joint study and to obtain relationships that are fair in both measurements and control, which increases the reliability of diagnosis. Since the controlled parameters, in the general case, can change over time, it is necessary, based on the assumption of the influence of only random variables, to introduce the norms of possible deviations. Going beyond these norms is the basis for decisionmaking. However, independent monitoring of individual indicators may, if correlated, lead to erroneous decisions. To prevent this, it is proposed to use statistical methods with multiparameter criteria to assess and diagnose the stability of complex objects. The paper proposes the use of T ^ 2 - Hotelling statistics to diagnose the state of complex objects. The physiological state of the human body was chosen as the object of study.
在实践中,复杂的目标由几个可以相互关联的参数来表征。这些设施包括医学、生态学、生物学、气象学、气候学、评估原材料质量、所有类型燃料和其他方面的大多数诊断设施/科目。对复杂对象状态的评估是通过测量与被研究对象参数相关的参数来确保被研究对象参数信息的最大完整性。测量和诊断过程在信息方面的共性程度是显著的,这导致它们需要共同研究,并获得在测量和控制方面公平的关系,从而增加诊断的可靠性。由于受控参数在一般情况下会随时间而变化,因此有必要在假设仅受随机变量影响的基础上引入可能偏差的规范。超越这些规范是决策的基础。然而,对个别指标的独立监测如果相互关联,可能会导致错误的决定。为了防止这种情况,提出了采用多参数标准的统计方法来评估和诊断复杂目标的稳定性。本文提出利用T ^ 2 -霍特林统计量来诊断复杂物体的状态。选择人体的生理状态作为研究对象。

The article briefly describes the existing and proposes novel approaches to the detection, estimation of the number and measurement of physical parameters of biological objects in the frames of computer vision systems. The object detection method is based on a two-stage algorithm: at the first stage, the approximate position of the object is determined using edge detection algorithms; at the second stage, graphic models of the object are built by creating graphical primitives. An algorithm for constructing graphical primitives is developed using the color of a biological object as a parameter. The presence of the second stage can significantly reduce both false positive and false negative results. To implement the presented model theoretical studies and practical experiments are carried out. During experiments, it was revealed that the proposed approach allows increasing the accuracy of determining biological objects, since it works with a color image and, accordingly, uses the ranges of digital color channels. In addition, the construction of graphical primitives, taking into account color ranges, makes it possible to estimate the physical characteristics of a biological object. The proposed two-stage technique for the automatic determination of biological objects makes it possible to solve the problems of positioning ultraviolet and low-frequency laser devices for point irradiation. The presence in the algorithm of the stage of constructing graphical primitives on biological objects makes it possible to estimate the degree of fatness of the animal, which is one of the components of determining its state of health, and can be part of an automatic system for contactless determination of the animal’s weight.
本文简要介绍了在计算机视觉系统框架下生物物体物理参数的检测、估计和测量的现有方法,并提出了新的方法。该目标检测方法基于两阶段算法:第一阶段,使用边缘检测算法确定目标的近似位置;在第二阶段,通过创建图形原语来构建对象的图形模型。提出了一种以生物对象的颜色为参数构造图形原语的算法。第二阶段的存在可以显著减少假阳性和假阴性结果。为了实现所提出的模型,进行了理论研究和实际实验。在实验过程中,发现所提出的方法可以提高确定生物物体的准确性,因为它适用于彩色图像,因此使用了数字颜色通道的范围。此外,考虑到颜色范围的图形原语的构建使得估计生物对象的物理特性成为可能。提出的两阶段生物目标自动定位技术,为解决点照射紫外和低频激光装置的定位问题提供了可能。在生物对象上构造图形原语阶段的算法的存在使得估计动物的肥胖程度成为可能,这是确定其健康状态的组成部分之一,并且可以成为非接触确定动物体重的自动系统的一部分。

The actual scientific problem of development methods aimed at reducing of hardware expenses in the logical circuit of the finite state machine, is solved by adaptation of the finite state machine (FSM) circuit to the characteristics of the implemented control algorithm. The object of the research encompasses process of optimization of finite state machines circuits. The subject of the research is the models and methods of synthesis of finite state machines, aimed at reducing the hardware expenses in the circuit of the machine. The research is based on a systematic analysis of the results of modern theoretical and applied developments made by domestic and foreign scientists in the digital control units sphere. The theoretical novelty is distinguished by the fact that a method is proposed for choosing constants in operations for operational state transitions on the base of the determinant of the matrix. The practical novelty lies in the implementation in Quartus by the behavioral method, in contrast to the classical method.

In this paper is experimentally determined a mechanism occurring in gradient magnetic field at two-collector bipolar magnetotransistors (BMT) when their collector currents are equal at induction B = 0. The effect represents a linear control of the sum of these currents by the gradient field. This phenomenon transform the BMT’s in magnetogradiometer sensor with high resolution. The experiments are carried out with prototypes realized by integrated silicon processes and innovative magnetomodular system featuring high and linear gradient. The sensitivity of BMT reaches S ≈ 300 μA/T for the selected operation mode. The maximal gradient obtained with new actuator system is 78 mT/mm. The results are very promising, as the magnetogradiometer further extends the functional possibility of BMT for sensor electronics and automation.

3D structured light scanners have been widely applied in the industry for high-speed and automatic quality control. A lot of scientific research reported that the obtainable accuracy and precision of the scanner vary considerably, and imperfect camera calibration is the main error source in the scanners. Actually, the VDI/VDE 2634 guideline, proposed by Association of German Engineers and Association for Electrical Engineering, Electronics and Information Technologies, has been used for evaluating the accuracy of stereo vision systems. However, the sensitivities of the camera parameters and disparity map for the test results of VDI/VDE 2634 guideline have not been well evaluated. This paper proposes a method for sensitivity analysis based on the principle of stereo vision, Monte Carlo method and VDI/VDE 2634 Part 2 guideline. We simulate the point cloud result of the ball bar artefact with 7 different arrangements and calculate the dimension of sphere diameter, sphere form and sphere-spacing. The simulation results show that the farther ball would have greater systematic error, and the deviation of the focal length and the disparity map would considerably affect the 3D point cloud reconstruction. Moreover, measurement of the ball bar artefact at the different depths of view would efficiently derive the maximum permissible error (MPE) of 3D structured light scanners.
三维结构光扫描仪在高速、自动化的质量控制中得到了广泛的应用。大量的科学研究报道了扫描仪的可获得精度和精度差异很大,相机标定不完善是扫描仪误差的主要来源。实际上,由德国工程师协会和电气工程、电子和信息技术协会提出的VDI/VDE 2634指南已被用于评估立体视觉系统的精度。然而,摄像机参数和视差图对VDI/VDE 2634准则测试结果的灵敏度尚未得到很好的评价。本文提出了一种基于立体视觉原理、蒙特卡罗方法和VDI/VDE 2634 Part 2指南的灵敏度分析方法。模拟了7种不同排列方式下球棒人工制品的点云结果,计算了球直径、球形和球间距的尺寸。仿真结果表明,球距越远,系统误差越大,焦距和视差图的偏差对三维点云重建有较大影响。此外,测量不同视场深度下的球杆伪影可以有效地得出三维结构光扫描仪的最大允许误差(MPE)。

In this work, a method for thermal control of filament supply in FFF/FDM 3D printing technology is presented. Thermal control method for filament supply is used to detect and avoid 3D printing process blocking caused by extruder jamming. Method is based on real-time temperature feedback from the 3D printer extruder. Two control parameters are continuously followed, first is the extruder thermal time-constant and second is the extruder heater switching frequency. Both parameters provide accurate feedback information on material flow through extruder and detects unwonted jamming during the 3D printing process. Correlation between filament material supply speed and control parameters has been established and presented. Control method does not require additional hardware equipment and uses embedded 3D printer extruder sensors and controllers.
本文提出了一种FFF/FDM 3D打印技术中长丝供给的热控制方法。采用长丝供给热控制方法,检测和避免挤压机卡壳造成的3D打印过程阻塞。该方法基于3D打印机挤出机的实时温度反馈。连续遵循两个控制参数,一是挤出机热时间常数,二是挤出机加热器开关频率。这两个参数都提供了通过挤出机的物料流的准确反馈信息,并检测了3D打印过程中不常见的干扰。建立并给出了长丝料供给速度与控制参数之间的关系。控制方法不需要额外的硬件设备,并使用嵌入式3D打印机挤出机传感器和控制器。

Thermal control method for filament supply is used to detect and avoid 3D printing process blocking caused by extruder jamming. Method is based on real-time temperature feedback from the 3D printer extruder. Two control parameters are continuously followed, first is the extruder thermal time-constant and second is the extruder heater switching frequency. Both parameters provide accurate feedback information on material flow through extruder and detects unwonted jamming during the 3D printing process. Correlation between filament material supply speed and control parameters has been established and presented. Control method does not require additional hardware equipment and uses embedded 3D printer extruder sensors and controllers.","PeriodicalId":287017,"journal":{"name":"2021 XXXI International Scientific Symposium Metrology and Metrology Assurance (MMA)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125507638","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}
