This paper presents the results of an investigation into the behavior of the functions of transforming the input data errors for different types of measurement systems’ computing components in order to use their generalized models developed on the basis of the finite automata theory. It is shown that, depending on the kind and value of an input data error transformation function (metrological condition of computing components), the errors of measurement results obtained with the systems’ measuring channels have a determinate character of changes in both static and dynamic regimes of computing components. Determined are the basic dependences of the errors of measurement results upon the input data errors, and upon the types of input data transformation functions; given are the results of their calculation. The investigation results demonstrate a linear character of the dependence of measurement result errors upon the input data errors ΔХ{(tn). In addition, the transformation function calculation f = ΔY{(tn)/ΔХ{(tn) gives its steady state value f = 1,0, i.e. a computing component does not transform the input data error, and does not reverse its sign. For the iterative procedures, the input data errors do not affect the final measurement result, and its accuracy. The measurement error values Δуn depend on the iteration number, and decrease with the increasing number. Of particular interest is the behavior of the function of transforming the input data errors: first, its values are dependent upon the number of iterations; second, f < 1, which clearly shows that the input data errors decrease with the increa­sing number of iterations; and third, the availability of values f = 0 indicates that the function of transforming the input data errors is able to «swallow up» the input data error at the end of the computational procedure. For the linear-chain structures, data have been obtained for a predominantly linear dependence of the measurement error Δs on the input data error Δх, and for the absence of the chain’s transformation function f dependence on the input data errors Δх. For the computing components having a cyclic structure, typi­cal is the same dependence of measurement errors Δt on the input data errors and on the behavior of transformation function ft/x which are specific to the above mentioned computing components that rea­lize iterative procedures. The difference is that the computing components having a cyclic structure realize the so-called (sub)space iteration as opposed to the time iteration specific to the computing components considered. The computing components having a complicated structure (e.g. serial-cyclic, serial-parallel, etc.) demonstrate the dependence of measurement errors on the input data errors which is specific to the linear link that, with such a structure, is determinative for eva­luating the measurement error. Also the function of transforming the input data errors behaves similarly.
本文介绍了对不同类型测量系统计算组件的输入数据误差转换函数的行为的研究结果,以便使用基于有限自动机理论开发的广义模型。结果表明,根据输入数据误差变换函数的类型和值(计算部件的计量条件),利用系统测量通道获得的测量结果的误差具有计算部件静态和动态变化的确定特征。确定了测量结果的误差对输入数据误差以及输入数据转换函数类型的基本依赖性;给出了它们的计算结果。研究结果表明,测量结果误差与输入数据误差Δx_{(tn)呈线性关系。此外,变换函数计算f=ΔY{(tn)/Δx_{(tn)给出了其稳态值f=1.0,即计算部件不变换输入数据误差,也不反转其符号。对于迭代过程,输入数据的误差不会影响最终的测量结果及其精度。测量误差值Δуn取决于迭代次数,并随着迭代次数的增加而减小。特别令人感兴趣的是转换输入数据误差的函数的行为:首先,它的值取决于迭代次数;其次,f<1,这清楚地表明输入数据误差随着迭代次数的增加而减少;第三,值f=0的可用性表明转换输入数据误差的函数能够在计算过程结束时“吞噬”输入数据误差。对于线性链结构,已经获得了测量误差Δs与输入数据误差Δх的主要线性相关性的数据,以及没有链的变换函数f与输入数据错误Δх相关性的数据。对于具有循环结构的计算组件,测量误差Δt与输入数据误差和变换函数ft/x的行为的相关性通常相同,这是上述实现迭代过程的计算组件特有的。不同之处在于,具有循环结构的计算组件实现了所谓的(子)空间迭代,而不是所考虑的计算组件特有的时间迭代。具有复杂结构(例如串行-循环、串行-并行等)的计算组件证明了测量误差对输入数据误差的依赖性,而输入数据误差是线性链路特有的,具有这种结构的线性链路对评估测量误差是决定性的。此外,转换输入数据误差的功能表现类似。

Розглянуто алгоритм, який дозволяє для дискретної вибірки із N значень на проміжку часу [–T/2, +T/2] оцінювати спектр потужності за допомогою фільтра з тією ж самою вузькою спектральною смугою у прямокутному часовому вікні, але з рівнем бічних пелюсток, менших на 4,3 дБ. Наведено приклади декількох «енергетичних» фільтрів. При цьому показано відгуки енергетичного фільтра порівняно з фільтром на основі традиційних часових вікон. Виникають можливості керування як шириною смуги фільтра, так і формою його вершини. Також суттєво збільшується розмірність простору змінних варіювання. Стосовно спектрального аналізу, йдеться відносно випадку, коли перетворення Фур’є виконується з двома різними часовими вікнами у часі. Підсумок формується із множників дійсних і недійсних частин першого та другого перетворення. При цьому не потрібно певних оптимальних властивостей від кожного із часових вікон, окремо оптимізується тільки кінцевий підсумок. Це ефективно, якщо одне із часових вікон нагадує вікно Кайзера-Бесселя. При цьому проведення згортки після перетворення Фур’є стає трудомістким, потребує багато обчислювальних операцій, та часове вікно краще використовувати безпосередньо до сигналу, який аналізується перед перетворенням Фур’є. Для таких часових вікон будування «енергетичного» фільтра збільшує час аналізу приблизно у два рази. Але швидкість обчислювань не зав­жди є визначальним фактором, а сумісне використання двох різних вікон замість одного розширює можливості аналізу. Результати роботи можуть бути  використані під час фільтрації приймальної потужності сигналу для різних систем, зокрема, для систем з максимальним придушенням шумової завади. Перспективно оптимізувати приймальну систему з горизонтальним робочим напрямком приймання. Задачу оптимізації у цьому випадку вирішують з урахуванням робочого діапазону як для середньої, так і для максимальної завади.
当你观察算法时,这允许N值随时间的离散样本[-T/2,+T/2]使用在直时间窗口中具有相同窄谱线的滤波器来评估功率谱,但侧羽小于4.3dB。给出了几种“能量”滤波器的例子。这显示了与基于传统时间窗的滤波器相比的能量滤波器反馈。过滤器的宽度和顶部都有控制选项。它还显著增加了可变空间的大小。就光谱分析而言,当毛发同时使用两个不同的时间窗口进行转换时,就会出现这种情况。摘要由第一次和第二次转换的实际部分和错误部分组成。这不需要每个时间窗口都有一些最佳属性,只需要单独优化结束摘要。如果其中一个时间窗口看起来像凯撒-贝塞尔窗口,这是有效的。在这样做的过程中,愤怒变换后的曲线变得困难,需要大量的计算操作,并且时间窗口更好地直接用于信号,在Fur变换之前对其进行分析。对于这样的时间窗口,构建“能量”过滤器会将分析时间增加大约两倍。但计算速度并不总是一个决定因素,但两个不同窗口的一致使用反而扩展了分析的可能性。当对不同系统的可接收信号功率进行滤波时,可以使用工作结果,特别是对于具有最大噪声抑制的系统。使用水平接收方向优化接收系统。在这种情况下,通过计算平均值和最大值的工作范围来解决优化任务。

The article considers the possibility of maintaining in statistical controllable state the technological pro­cess with the use of control charts of accumulated sums. The principles of construction of these charts, features of the process disorder detection are shown. The feature of the control charts of accumulated sums is that, the decision regarding the statistical controllability of the pro­cess is made taking into account the preliminary information. The dots mapped do not correspond to indivi­dual measurement results or statistics, they display information about all the results obtained, from first to last, inclusive. This feature allows you to respond more quickly to signs of process disorder than when working with Shewhart control charts, where sample statistics are used for analysis, which are independent control results. The characteristics relation of the charts with the establishment of errors of the 1st and 2nd kind when interpreting them using the hypothesis testing apparatus is considered. The article presents the theoretical substantiation and approaches to the application of sequential LQ (likelyhood quotient) criterion in process monitoring, describes the main parameters that influence decision making. A graphical interpretation of the application of the LQ criterion is given to improve the perception of information. The method of graphical estimation of the process disorder with the use of V-mask, which is associated with the reversed LQ criterion, is also considered, if a disorder of the technological process is detected and it is necessary to set the time when it happened. At the same time, the right approach to constructing a V-mask template is very important, since in addition to the «opening» angle of the mask, the scaling factor must be taken into account. This coefficient is the ratio of the scale of the ordinate to the abscissa axis, and its failure to apply will lead to incorrect interpretation of the control results. A specific numerical example with an appropriate graphical representation of the results is considered.
本文考虑了利用累积和控制图将技术过程保持在统计可控状态的可能性。这些图表的构造原理,展示了过程无序检测的特点。累加和控制图的特点是,在考虑初步信息的情况下,决定过程的统计可控性。映射的点与单独的测量结果或统计数据不对应,它们显示了从第一个到最后一个(包括首尾两个)的所有结果的信息。与使用休哈特控制图时相比,此功能使您能够更快地对过程紊乱的迹象做出反应,休哈特控制图表中的样本统计数据用于分析,这是独立的控制结果。在使用假设检验装置解释图表时,考虑了图表的特征与第一类和第二类错误的建立之间的关系。本文介绍了序列LQ(似然商)准则在过程监控中应用的理论依据和方法,描述了影响决策的主要参数。给出了LQ准则应用的图解解释,以改善对信息的感知。如果检测到工艺过程的紊乱并且有必要设置其发生的时间,则还考虑使用与反向LQ准则相关的V型掩模对过程紊乱进行图形估计的方法。同时,构建V型掩模模板的正确方法非常重要,因为除了掩模的“打开”角度外,还必须考虑比例因子。该系数是纵坐标与横坐标轴的比例,如果不应用该系数,将导致对控制结果的错误解释。考虑了一个具有适当图形表示结果的具体数值示例。

Optical System for Led Luminaire Led灯具的光学系统

Lighting devices are an important element of a large number of technical systems, including road, living, industrial lighting, lighting systems of vehicles. It is known that the light instrument must fulfill two basic lighting tasks: to redistribute the light source of light source in the right way and to limit its dazzling effect. The introduction of light-emitting diodes (LEDs) for lighting necessitated a completely new quality in the construction of luminaires. The different production technology required new methods and designing tools. It also challenged designers with new problems to solve. LEDs are light sources emitting in one hemisphere, which requires a special approach to designing an LED lighting unit. However, for the illumination of premises with high spans or streets, roads such a light distribution is not suitable. For luminaires with solid-state light sources, other materials and new technology must be used; moreover, light distribution needs to be formed using different methods. This paper presents the design process of a LED luminaire from concept to implementation, exemplified by road lighting, and describes the methods and procedures used by the designer. Also, technological problems influencing the quality of the above lighting are addressed. Optical systems for LEDs are considered. The peculiarities of the use of secondary optical elements in the form of lenses for purpose of obtaining different diagrams of the spatial distribution of light intensity of light-emitting diodes are analyzed. Features and problems of calculation of secondary optical systems are considered. Massive collimators do not have to be elements that focus a narrow beam of light. They are able to form a beam in accordance with any accepted distribution that is appropriate for a given application. They are also able to form a beam in a specific way that is required for outdoor lighting luminaires. The stages of a project for designing a road luminaire require the application of the knowledge and experience gained in various research projects. The design methods described in this paper have been developed designing activity and are also to be used successfully in lighting production.  
照明装置是大量技术系统的重要组成部分,包括道路、生活、工业照明、车辆照明系统等。众所周知,照明仪器必须完成两个基本的照明任务:将光源的光源以正确的方式重新分配,并限制其眩光效果。照明用发光二极管(led)的引入要求灯具的构造达到一个全新的质量。不同的生产技术需要新的方法和设计工具。它还向设计师提出了需要解决的新问题。LED是在一个半球发射的光源,这需要一种特殊的方法来设计LED照明单元。但是,对于高跨度房屋或街道、道路的照明,这样的配光方式是不合适的。对于采用固态光源的灯具,必须采用其他材料和新工艺;此外,需要使用不同的方法形成光分布。本文以道路照明为例,介绍了LED灯具从概念到实现的设计过程,并描述了设计师使用的方法和步骤。此外,还讨论了影响上述照明质量的技术问题。考虑了led的光学系统。分析了利用透镜形式的二次光学元件获得发光二极管光强空间分布图的特点。讨论了二次光学系统的特点和计算问题。大型准直器不一定是聚焦窄光束的元件。它们能够按照适用于给定应用的任何可接受的分布形成光束。它们还能够以特定的方式形成室外照明灯具所需的光束。道路灯具设计项目的各个阶段需要运用在各种研究项目中获得的知识和经验。本文所描述的设计方法已经发展成为设计活动,并将成功地应用于照明生产。

Investigating pulse in different parts of the body is of great interest to doctors. The purpose is the development of metrological maintenance, calibration and certification of photometric instruments [1—3]. Photoplethysmograph is designed to record changes in optical density of a person’s body area with a beam of light reflected in the light [4—6]. Measurements are carried out non-invasively [7]. Such device registers pulse wave (PW) signals and reference ECG with computer processing, Fig. 1—2 [8—10]. A working measure (LED) was created and calibrated using an optical radiation power meter based on the substitution method [11], test bench is at Fig. 3, calibration results — in Table 1 and Fig. 4. Test bench for device calibration and an optical radiator are at Fig. 5—6, view of calibrated signal — at Fig. 7. As a result of calibration (Table 2) the dependence of the output signal on LED power supply (Fig. 8) is obtained, and the calibration dependence is shown at Fig. 9. In the test bench for SMC used standardized light filters KNS-01 at a wavelength of 630 nm (Fig. 10a). The calibration curve is calculated as the dependence of the relative coefficient of inverse light dispersion (RCILD) on PW (Fig. 10b, Table 3). The view of output signal is at Fig. 11. As a result of SMC, the limits of permissible absolute error of 2 % in the range of RCILD (15—100) % are defined.

The article presents the results of validation for the method of mea­suring the lateral stability in tractors, trailers and agricultural machines. The method was developed in the testing laboratory of the State Scientific Institution «Leonid Pogorely Ukrainian Research Institute for Forecasting and Testing Equipment and Technologies for Agricultural Production», Kharkov branch. The method developed for measuring the angle of lateral stability is based on measuring the mass of the machine on boards in a horizontal and inclined position. Evaluation of lateral stability is carried out through an indirect indicator — the ratio of the mass of the machine bead in a horizontal position and inclined. The application of the develo­ped method does not require determination of the coordinates of the cen­ter of mass of the machine and the use of platform stands, but provides only for measuring the mass of the machine in a horizontal position and at an angle when lifting one of the sides. A method for calculating the metrological characteristics of the proposed method is given. The error in measuring the angle of transverse stability of the proposed method consists of the error in measuring the mass of the machine and the uncertainty in measuring the angle of elevation of the machine’s edge. These values are independent and uncorrelated. The measurement error of the lateral stability angle is determined for the range of the real values masses of the machines and the angle at which they can be lifted aboard in safety conditions. As a result, validation is established. The method of measuring the lateral stability of a machine by successively weighing its sides is sui­table for use. Its following characteristics. Requirements for the accuracy of measuring instruments: the measurement error of the angle of inclination of the machine — no more than ± 0,1°; measurement error of the mass of the machine — no more than ± 4 kg. The total absolute error of the me­thod: when the mass of the machine is (2000)—(2300) kg — not more than 1,5°; with a mass (2300)—(10000) kg — 1,0°; with a mass of 10,000 kg or more — 0,5°. The range of measured values of the lateral stability angle is (25—45)°. The angle at which the machine climbs is (5—15)°. The scope of application of the method: tractors, trailers, agricultural machines. Table — 4. Figure — 4. References — 10.
本文介绍了拖拉机、挂车和农业机械横向稳定性测量方法的验证结果。该方法是在国家科学机构“列昂尼德·波戈雷利乌克兰农业生产预测和测试设备与技术研究所”哈尔科夫分所的测试实验室开发的。所开发的测量横向稳定角的方法是基于测量机器在水平和倾斜位置上的质量。横向稳定性的评估是通过一个间接指标进行的-机器头在水平位置和倾斜位置的质量之比。该方法的应用不需要确定机器的质心坐标,也不需要使用台架,而只提供了在水平位置和抬起一侧时以一定角度测量机器的质量。给出了该方法计量特性的计算方法。该方法测量横向稳定角的误差包括测量机器质量的误差和测量机器边缘仰角的不确定度。这些值是独立且不相关的。横向稳定角的测量误差是在机器的实际质量和在安全条件下可以上船的角度范围内确定的。因此,建立了验证。这种通过连续称量机器侧面来测量机器横向稳定性的方法是适合使用的。其特点如下。对测量仪器精度的要求:机器倾斜角度的测量误差——不大于±0.1°;机器质量的测量误差-不大于±4kg。该方法的总绝对误差:当机器质量为(2000)- (2300)kg时-不大于1.5°;质量(2300)- (10000)kg - 1°;质量大于等于10,000公斤- 0.5°。横向稳定角的测量值范围为(25-45)°。机器爬升的角度为(5-15)°。本方法适用范围:拖拉机、挂车、农用机械。表4。图- 4。参考文献- 10。

Parameters of the total electrical resistance (impedance) are often used for substances properties identification, in particular, for heterogeneous liquids. In such conditions, the quality of the product is compared with the measured impedance (or full admittance) on alternating current [7, 8]. To do this, the industrial meters (RLC-meters), based on equivalent circuits, for example, in accordance with the «Warburg impedance scheme», are used. The disadvantages of such measurement tools are the uncertainty of the measuring circuit model components, the choice limitations of electrical parameters measuring means with the necessary sensitivity, as well as the high cost. Previously, the authors developed a new method of separate determination of active and capacitive impedance components for a heterogeneous fluid. This method is based on measuring at two close frequencies the levels of electric current and voltage with the subsequent calculation of the impedance components by a certain algorithm [1]. It is taken into account that the electrical properties of suspensions are usually caused by several types of charge carriers and depend a lot on the measurement conditions, in particular, the type (constant or alternating) and frequency of the electric current (6)…(8) [2, 3]. A new theoretical analysis and comparison of its results (9)…(11) with experimental data to determine the electrical properties of a water-graphite suspension (Table 1) revealed that the sensitivity of one of the impedance components (active or capacitive) to changes in a specific fluid property is higher than the total impedance. The experimental dependencies of the impedance components of a model fermented milk product on its fat content at low frequencies (up to 400 Hz) and voltage (up to 5 V) of electric current are presented (Figures 2, 3). These data confirmed the possibility of practical use of the design results for rapid quality assessment of various electrically conductive heterogeneous liquids with the necessary sensitivity and accuracy of measuring instruments.
总电阻(阻抗)参数常用于物质性质鉴定,特别是非均相液体。在这种情况下,将产品的质量与交流电的测量阻抗(或全导纳)进行比较[7,8]。为此,使用了基于等效电路的工业仪表(rlc仪表),例如,根据«Warburg阻抗方案»。这种测量工具的缺点是测量电路模型元件的不确定性,具有必要灵敏度的电参数测量手段的选择限制,以及成本高。此前,作者开发了一种新的方法来分离测定非均质流体的有源和容性阻抗分量。该方法是基于在两个相近的频率测量电流和电压的电平,然后通过一定的算法[1]计算阻抗分量。考虑到悬浮液的电学性质通常是由几种载流子引起的,并且在很大程度上取决于测量条件,特别是电流的类型(恒定或交流)和频率(6)…(8)[2,3]。为了确定水-石墨悬浮液的电性能(表1),一项新的理论分析和结果(9)与实验数据(11)进行了比较,结果表明,其中一个阻抗分量(有源或容性)对特定流体特性变化的灵敏度高于总阻抗。在低频率(高达400 Hz)和电压(高达5 V)的电流下,模型发酵乳制品的阻抗成分对其脂肪含量的实验依赖关系(图2,3)。这些数据证实了设计结果在实际应用中快速评估各种导电非均质液体质量的可能性,并具有必要的测量仪器的灵敏度和精度。

This work is devoted to the precision evaluation of the minimum detectable activity (MDA) measurement of gamma radiation radionuc­lides 137Cs and 60Co using plastic scintillators (PS). Scintillators are part of the detectors, which are sensitive elements of radiation portal moni­tors (PM). PS were produced at the Institute for scintillation materials of the National Academy of Sciences of Ukraine (ISMA NAS of Ukraine). The evaluation was generate in accordance with State standard of Ukraine ISO 5725-2:2005 [1] through statistical processing of experi­mental material. This made it possible to take into account the factors that determine the scattering of results without a model equation. Influence of PS sizes, energy radiation detected and distance from PS to the source of ionizing radiation (SIR) on the value of MDA precision measurement was studied. Precision coefficients of radionuclides MDA measurement evalua­ted when changing PS sizes from 500×300×50 mm (7500 cm3) up to 500×500×50 mm (12500 cm3), changing the energy radiation detected from 662 keV (137Cs) until 1332 keV (60Co), changing the distance from the PS to SIR from 10 to 50 cm. The results are presen­ted in Fig. 6—9 and Table. Found, that the greatest contribution to the increase in MDA precision coefficient measurements makes a change in the irradia­tion geometry. It is shown that when distance from PS to SIR increases from 10 to 50 cm, precision values increase: when registering 137Cs, from 3,9 to 7,0 % (V = 7500 cm3) and from 3,6 to 6,3 % (V = 12500 cm3); when registering 60Co, from 3,1 to 4,3 % (V = 7500 cm3) and from 3,2 to 3,8 % (V = 12500 cm3). It is established, that the obtained results are due to the change in the contribution of background count rate to PS count rate under different measurements conditions. This contribution affects on the value of sensitivity coefficient and consequently on the value of MDA and precision coefficient.
本文研究了利用塑料闪烁体(PS)测量γ辐射放射性核素137Cs和60Co的最小可探测活性(MDA)的精度评价。闪烁体是探测器的一部分,是辐射门户监视器(PM)的敏感元件。PS是在乌克兰国家科学院闪烁材料研究所(ISMA NAS of Ukraine)生产的。根据乌克兰国家标准ISO 5725-2:2005[1]对实验材料进行统计处理,得出评价结果。这使得在没有模型方程的情况下考虑决定结果散射的因素成为可能。研究了PS尺寸、检测能量辐射以及PS到电离辐射源(SIR)的距离对MDA精密度测量值的影响。将PS尺寸从500×300×50 mm (7500 cm3)改变到500×500×50 mm (12500 cm3),将检测到的能量辐射从662 keV (137Cs)改变到1332 keV (60Co),将PS到SIR的距离从10改变到50 cm时,评估了放射性核素MDA测量的精度系数。结果如图6-9和表所示。发现,对MDA精度系数测量值的增加贡献最大的是辐照几何形状的变化。结果表明,当从PS到SIR的距离从10 cm增加到50 cm时,精度值增加:当记录137Cs时,从3,9 %增加到7,0 % (V = 7500 cm3),从3,6 %增加到6,3 % (V = 12500 cm3);当注册60Co时,从3,1到4,3 % (V = 7500 cm3)和从3,2到3,8 % (V = 12500 cm3)。结果表明,在不同的测量条件下,背景计数率对PS计数率的贡献发生了变化。这种贡献影响灵敏度系数的值,从而影响MDA和精度系数的值。

Influence of PS sizes, energy radiation detected and distance from PS to the source of ionizing radiation (SIR) on the value of MDA precision measurement was studied. Precision coefficients of radionuclides MDA measurement evalua­ted when changing PS sizes from 500×300×50 mm (7500 cm3) up to 500×500×50 mm (12500 cm3), changing the energy radiation detected from 662 keV (137Cs) until 1332 keV (60Co), changing the distance from the PS to SIR from 10 to 50 cm. The results are presen­ted in Fig. 6—9 and Table. Found, that the greatest contribution to the increase in MDA precision coefficient measurements makes a change in the irradia­tion geometry. It is shown that when distance from PS to SIR increases from 10 to 50 cm, precision values increase: when registering 137Cs, from 3,9 to 7,0 % (V = 7500 cm3) and from 3,6 to 6,3 % (V = 12500 cm3); when registering 60Co, from 3,1 to 4,3 % (V = 7500 cm3) and from 3,2 to 3,8 % (V = 12500 cm3). \u0000It is established, that the obtained results are due to the change in the contribution of background count rate to PS count rate under different measurements conditions. This contribution affects on the value of sensitivity coefficient and consequently on the value of MDA and precision coefficient.","PeriodicalId":52864,"journal":{"name":"Metrologiia ta priladi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43917805","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}
