PRINCIPLES OF BUILDING OF AUTOMATIC MEASURING VOLUME OF AGRICULTURAL PRODUCTS AND MATERIALS DEVICES
Authors: Sedov A. M.
Published: November 2019

Many qualitative and quantitative properties of products, materials, and parameters of technological processes in agricultural production and other sectors of the economy are characterized by volume indicators. Based on analytical and experimental studies a unified system of automatic volumetric meters has been developed taking into account three basic principles: “discharge” of a gas-filled chamber to a measuring capacity; generation of a linearly increasing pneumatic signal in the free volume of the measuring capacitance; digital quantization of the free volume of the measuring capacitance. The system is unified by the elemental base, power levels and output signals and allows you to solve the main tasks of measuring, monitoring and signaling the volume of most agricultural products and materials; create fundamentally new automation tools from standardized units on the basis of the volumetric module by adding other modules (weighting, computing, differentiating, comparisons, etc.). Analytical expressions of the static characteristics of the developed volumes are obtained experimental studies have confirmed their reliability. The rational design and tuning parameters of the devices are determined taking into account the specifics of the physical properties of agricultural products and materials.

Published: November 2019

The article presents the research results of the influence of biologically active substances and the herbicide Pulsar (active ingredient - imazamox) on the enzymatic activity in leaves, biological productivity and seed quality of the mid-ripening soybean variety Kitrossa. Field experiments were conducted on meadow chernozem soils of the All-Russian Scientific Research Institute of Soybean in 2017-2018 years. The natural preparations were used as biologically active substances: ExtraKor - obtained by processing Dahurian larch and Betulin - birch bark extract. As a result of the conducted research, it was found that the annual application of the herbicide Pulsar in the phase of the 3rd ternate leaf led to a decrease in the specific activity of the peroxidase enzyme compared to the control. The treatment of seeds and vegetative plants of the soybean variety Kitrossa with Betulin and ExtraKor preparations contributed to an increase in the specific activity of the being studied enzyme in the leaves that indicates the stimulation of biochemical processes and the ability to increase adaptive potential. Thus, it was revealed that the combined use of biologically active substances led to a decrease in adverse environmental factors and the mobilization of protective mechanisms of plants that ensured a decrease in the negative influence of the herbicide on soybean plants. As a result, on the average for 2 years of research, the biological productivity of seeds increased to 3,08 t/ha. The germination energy from the application of biologically active substances increased on the average by 5%.

Published: November 2019

The application of solid modelling tools is considered when creating three-dimensional models of a straight circular cone and when studying its sections in AutoCAD. The results are presented that AutoCAD allows obtaining for a section by planes almost parallel to one or two generators. The boundary values of the angles between the plane and the generators, which determine the presence or absence of parallelism, are found. Methods are proposed for obtaining the parameters of the canonical equations of curves representing conical sections for cases when the corresponding curve (hyperbola or parabola) is modelled in AutoCAD using splines. The application of the proposed methods in the educational process is described, which makes it possible to strengthen the relationship of what is stated in the study of sections of descriptive geometry of the material with the development of methods for generating three-dimensional models, solid-state modelling tools and analytical geometry.

Towards the suppression of blend chains using Euler operators and open geometric modeling kernel
Authors: Сляднев Сергей , Slyadnev Sergey , Турлапов Вадим , Turlapov Vadim
Published: November 2019

This paper presents a CAD model simplification procedure which consists of recognition and suppression of certain types of blend chains. The proposed method involves Euler operators KEV, KEF, and KFMV, which are developed on top of open-sourced geometric modeling kernel. The simplification process employs two stages: recognition and suppression. The suppression stage ensures the geometric and topological validity of the simplification result. The present approach is targeted for use in a batch mode, which poses strict requirements to the robustness of the suppression algorithm. The essential properties of the presented approach are its sustainability, the predictability of the result and the extensible architecture, which allows for adding new topological cases without affecting the algorithm’s core. At the recognition stage, the algorithm constructs an attributed adjacency graph, which is then enriched with such information as edges’ types, their properties, and the assumed kinds of blend faces. At the suppression stage, the algorithm iterates the adjacency graph and composes the blend candidate faces into the chains. For each face in a chain, a local topology analysis is performed to determine the corresponding sequence of Euler operators which are supposed to eliminate that face. The algorithm allows for extensions through adding descriptors of the new topology situations into the processing. After the Euler operators are done, the affected edges are reconstructed to obtain a watertight boundary representation of the model.

Authors: Бондарев Александр , Bondarev Aleksandr , Галактионов Владимир , Galaktionov Vladimir
Published: November 2019

The paper considers the tasks of visual analysis of multidimensional data sets of medical origin. For visual analysis, the approach of building elastic maps is used. The elastic maps are used as the methods of original data points mapping to enclosed manifolds having less dimensionality. Diminishing the elasticity parameters one can design map surface which approximates the multidimensional dataset in question much better. To improve the results, a number of previously developed procedures are used - preliminary data filtering, removal of separated clusters (flotation). To solve the scalability problem, when the elastic map is adjusted both to the region of condensation of data points and to separately located points of the data cloud, the quasi-Zoom approach is applied. The illustrations of applying elastic maps to various sets of medical data are presented.

Electroencephalogram is time series signals therefore, a Gramian Angular Fields conversion has been applied to convert it into images. GAF conversion was used for classification EEG with Convolutional Neural Network (CNN). GAF images are represented as a Gramian matrix where each element is the trigonometric sum between different time intervals. Grayscale images were applied for recognition to reduce numbers of neural network parameters and increase calculation speed. Images from each measuring channel were connected into one multi-channel image. This article reveals the possible usage GAF conversion of EEG signals to motion imagery recognition, which is beneficial in the applied fields, such as implement it in brain-computer interface.

Published: November 2019

The monocular visual odometry algorithm involves several basic steps and for each of them there is a number of methods. The purpose of this work is to conduct practical research of methods for key point detection and the optical flow calculation in the problem of determining the unmanned ground vehicle proper motion. For detection method research conduction the image panel containing various distortions typical for follow robot shot was made. It has been educed that among the accounted methods FAST finds the largest number of points within the minimum elapsed time. At the same time image distortions strongly affect the results of the method, which is negative for the positioning of the robot. Therefore the Shi-Tomasi method was chosen for key points detection within a short period of time, because its results are less dependent on distortion. For research undertake a number of video clips by means of the follow robot shot was made in a confined space at a later scale of the odometry algorithm. From experimental observations the conclusions concerning the application of Lucas-Kanade optical flow method tracking the identified points on the video sequence have been made. Based on the error in the results obtained it was implication that monocular odometry cannot be the main method of an unmanned vehicle positioning in confined spaces, but in combination with probe data given by assistive sensors it is quite possible to use it for determining the robotic system position.

The paper presents an improvement of Monte-Carlo ray tracing which changes ray emission from a light source to accelerate convergence i.e. reduce the noise remained after the given run time. It is mainly intended for interior scenes illuminated from outside (e.g. skylight) through windows or other holes. The rays from light sources are generated so that they are directed to these windows. In other words, the number of rays is increased for directions that contribute to the camera image. It is shown that the proposed method allows calculating image with desirable quality several times faster.

Published: November 2019

Photo-realistic rendering systems on CPU traditionally have significant flexibility achieved mainly by the ability for end user to write custom plugins or shaders. The same cannot be said about majority of photo-realistic GPU renderers. Most «classic» approaches to design of user-extendable software on CPU, such as object-oriented plugins are not very well suited for GPU programming. In this paper we propose a restricted approach to developing extendable GPU rendering system at low development cost. Our hardware agnostic light-weight approach can be applied to existing rendering systems with minimal changes to them. We apply our approach to the problem of procedural textures implementation and show that, in addition to simplicity, our approach is faster then existing GPU solutions.

In the paper we present the situation which had required visualization of a large amount of non-trivial objects, such as supercomputer’s tasks. The method of visualization of these objects was hard to find. Then we used additional information about an extra structure on those objects. This knowledge led us to an idea of grouping the objects into new generalized ones. Those new artificial objects were easy to visualize due to their small quantity. And they happened to be enough for the cognition of the original problem. That was a successful change of point of view. As a whole, our work belongs to a high-performance computing performance visualization area. It gains valuable attention from scientists over the whole world, for example [1-2].

El derecho al pago del Seguro de Depósitos por el cierre de entidades financieras del sector popular y solidario en el Ecuador
Authors: Paredes Paredes Eduardo , Velaña Bayas Bryan
Published: November 2019

El Estado ecuatoriano garantiza el derecho al pago del Seguro de Depósitos a todas las personas que fueron afectadas por el cierre (liquidación forzosa) de entidades financieras del sector popular y solidario; el cual, protege de forma limitada los depósitos efectuados en las entidades descritas, con el fin de que puedan recuperar sus ahorros conforme la ley. Se realiza un análisis de la normativa y de los procedimientos realizados por las entidades de control; y se determina que el ordenamiento jurídico, no contribuye a una eficiente devolución de los depósitos a los afectados, lo cual vulnera derechos y principios constitucionales.

Authors: Arias Pérez Mauricio , Bastidas Ramos María , Salazar Mejía César
Published: November 2019

La deserción estudiantil es el abandono de la carrera en la que se matricula un alumno por la influencia de factores positivos o negativos, o por circunstancias internas o externas. El presente estudio analiza las principales causas que ocasionan la deserción de los estudiantes de la Universidad Técnica de Ambato de las carreras de Contabilidad y Auditoría, Economía, Marketing y Gestión de Negocios, Mercadotecnia, Organización de Empresas y Administración de Empresas. Los resultados más importantes indican que el abandono de los estudios se encuentra relacionado con el ámbito económico y personal, además debe existir una adecuada motivación y tutoría académica. La metodología que se utilizó fue observación directa, encuestas y análisis de datos a los estudiantes de las carreras mencionadas anteriormente, con un enfoque cuali – cuantitativo que permitió realizar un análisis exploratorio de datos para establecer las causas de deserción.

El desplazamiento de las fuentes de agregación de valor en la cadena de maíz duro ecuatoriana
Authors: Granda Aguilar Jorge
Published: November 2019

Este estudio estima el desplazamiento de las fuentes de agregación de valor en Ecuador según la lógica de la “curva agregada de la sonrisa” que recepta los cambios entre los insumos participes–primarios, secundarios, terciarios–. Con base a los costos de los productores de la cadena de maíz amarillo, se determina ese tipo de desplazamientos mediante una estimación de corte transversal cuya inclinación resulta más a tono con la detectada por Baldwin et. al., 2014 en varios países asiáticos entre 1985-1995, y no tanto la que encuentran entre 1995- 2005 cuando se aprecia una tercerización más clara de la producción.
Palabras clave: Fuentes de agregación de valor, tercerización de la producción, cadena productiva del maíz amarillo.

El impuesto a la plusvalía y su impacto en el sector de la construcción en el cantón Ambato, provincia de Tungurahua
Authors: Mera Bozano Edgar , Salazar Mejía César , Solís Gavilanes Alex
Published: November 2019

El estudio establece la afectación de la Ley de plusvalía para evitar la especulación de la Tierra en el desempeño del sector de la construcción del Cantón Ambato; la desinformación generada por los medios de comunicación y las cámaras de la construcción atribuyó a la normativa el decrecimiento económico en el sector, en apenas un año desde su publicación, de ahí su derogatoria en el año 2018 mediante consulta popular; sin embargo analizados los factores se concluye que no fue la vigencia de la Ley la causante de la recesión del sector sino otros factores macro-económicos. Dado el enfoque de la investigación se acudió a fuentes de información de las bases de datos oficiales de Instituciones estatales relacionadas.

Capital humano. La educación en Ecuador y su rentabilidad
Authors: Espinoza Estrella Bryan , Villarruel Meythaler Ramiro
Published: November 2019

Desde el año 2008 una serie de reformas laborales han sido implementadas en Ecuador bajo el principio de la mejora de las condiciones de vida del trabajador. Incluso, el sector de la educación fue también reestructurado para alcanzar mayores niveles de cobertura y calidad, y, junto con ello, los ingresos laborales se incrementaron dado este nuevo marco jurídico. Es así como, dentro de este contexto de reformas legales, el presente artículo analiza la rentabilidad de la educación y de sus diferentes niveles de instrucción educativa a través del desarrollo de modelos econométricos de regresión.
