DETERMINATION OF THE ERROR OF MEASURING THE HEIGHTS OF THE OBJECTS DURING THE AUTOMATIC PROCESSING OF STEREO PICTURES
Get PDFCurrently, information on the spatial description of objects is used in many areas of human activity. One of these types of information is the coordinates of objects. Such data are used in cartography, in the construction of digital maps and 3D models, for the operation of navigation aids, etc. In the automated creation of digital models of terrain relief, one of the main qualitative indicators is the accuracy of determining the height of objects. The main influence on this indicator is made by the parallax measurement error when processing stereo images. To obtain a formula for calculating the accuracy of measuring the height of objects, let’s use the expansion of the function in a Taylor series. Using the Cramer-Rao formula for the potential accuracy of measuring the coordinates of the image of the object in the image, the Fourier transform and Parseval's equality, the formula for the potential accuracy of combining stereo images (parallax measurements) is obtained. The analysis of the obtained formulas shows that the image alignment accuracy deteriorates with an increase in the noise power spectral density in the first and second images and a decrease in the similarity of one image to another, as well as with a decrease in the effective width of the mutual spatial spectrum of stereo images. As the value of the stereo recognition basis increases, the error in measuring the heights of objects first improves, and then worsens. This deterioration is due to the fact that stereo pair images are obtained from different spatial points and at the same time perspective distortions and distortions in relief appear on the images. Accordingly, with an increase in the basis of shooting, these distortions will increase. This approach can be used when planning the mode of stereo shooting and equipment for removing the earth's surface for mapping, obtaining 3D models, etc
NONLINEAR METHODS OF CALCULATION OF STRUCTURES UNDER THEIR COMPLEX LOADING
Get PDFCalculations of building structures, the development and improvement of calculation methods, the use of numerical methods in solving these problems are one of the promising areas.
The paper presents on the basis of the theory of plastic flow with hardening the equations of state in increments, the equations of virtual work, the geometric equations in increments for small elongations, shifts, and rotation angles.
The calculations take into account, depending on the intensity of the current load, the elastoplastic properties of the material, both the structure and the soil environment interacting with it, with a complex process of loading [1-3].
For numerical implementation, the equations arising from the conditions of Genius – applicable to concrete, Coulomb - Mohr – applicable to soil environments are applicable.
The information presented is implemented in the form of software systems that make it possible to obtain numerical results of solutions to problems in the calculation of underground structures.
An example of calculating a structure based on these methods using a software package is also given. The elastoplastic properties of the material, both the structure and the soil medium interacting with it, are taken into account during the complex process of their loading
PROSPECTS FOR THE USE OF PHYSICAL MODIFICATION STARCH IN FOOD PRODUCT TECHNOLOGY WITH COLLOID STRUCTURE
Get PDFThe aim of research is studying the rheological properties of gelatinized starch dispersions based on physical modification starches, depending on technological factors.
Realization of the research aim will allow to obtain products (sauces, filler creams for confectionery products, etc.) using physical modification starches that are capable of selling products with specified structural and mechanical indicators, quality and safety indicators. And also ensure the rational use of raw materials, reduce the complexity of the technological process of production of culinary products.
The current trends in the development of starch technology for physical modification and their use in food technology are analyzed. A review of literature data has become the background for the use of these starches in food technology, which primarily draws attention to the colloidal stability of food systems.
A decrease in viscosity (the tendency ηmax=>ηmin) indicates the destruction degree of structural elements under the influence of mechanical stress and thermolysis. Tapioca starches “Endura”, “Indulge” and waxy maize starch “Prima” have practically the same values η (min) and η (max), which indicates the stability of the structure of gelatinized starch dispersions. This is probably due to the fact that grains with a monodisperse fraction (≈83 %) swell and gelatinize equivalently.
A study of the effect of acids on the formation and stability of gelatinized starch dispersions shows that the most pronounced stability is characterized by dispersions based on Prima waxy starch and Endura tapioca.
The gelatinized starch dispersions based on corn starch amylopectin exhibit low stability during the maximum peak gelatinization depending on the effect of sugar and acid.
A thermodynamic study of physical modification starches wi carried out, which confirms the amount of energy expended on unpacking the starch grain, which confirms the initial gelatinization of starches
FABRICATION OF PhC STRUCTURES BY USING NANOIMPRINT LITHOGRAPHY AND THEIR OPTICAL PROPERTIES
Get PDFThe contribution deals with creating structure, which have unique properties for influencing the spectrum of light. Since these structures exhibit the period under the diffraction limit of visible light or UV radiation, they can’t be fabricated by standard photolithography. As a result, this nanoscale structure must be prepared with progressive nanostructure patterning technology known as nanoimprint lithography (NIL). Especially, in our work UV-nanoimprint lithography was used. Considering preservation of low production costs, which plays a crucial role in the industry, the UV-nanoimprint lithography will be best suit for this purpose. Using this technology result with respect to reproducibility and uniformity of created nanostructure has been achieved. Ability of influencing light spectrum for nanostructures with the period of 800 nm and 600 nm with various feature size were presented with observation and simulation also
COMPARISON A RUNNING SMOOTHNESS OF A WHEELED TRACTOR WITH A SEMITRAILER TANK OR UNIT WHILE DRIVING ON ASPHALT-CONCRETE SURFACE
Get PDFThe problem of providing functional stability while moving vehicles arises during research of the types of transport works used in agriculture. A wheeled tractor with trailer or semitrailer units is used as a vehicle in the agricultural sector. These days most manufacturers of tractor technology increase the performance of transport work, such as increasing of engines power and cargo transportation. This trend is dangerous, especially when transporting units with variable mass (tanks), because the transportation of liquid cargo leads to significant self-oscillations, which effects on the movement dynamics. One of the studies that characterizes the dynamics of the vehicle movement is running smoothness. This research can provide information about the driver's comfort and vibration occurrence in a vehicle. The materials in this article are basic in the study of running smoothness of a tractor with a variable mass unit and also provide prerequisites for the coverage of the recommendations for reducing driver seat and tractor frame vertical acceleration

INVESTIGATION OF THE INFLUENCE OF SESAME ANTIOXIDANTS ON THE OXIDATIVE STABILITY OF PROVITAMIN A
Get PDFMicrobiological oil solutions of provitamin A (β-carotene) as a dietary supplement are not widely used due to their low oxidation stability. The aim of research is determination of the effect of sesame antioxidants on the oxidative stability of provitamin A in oil solutions.
The peroxide number of vegeTable oils is determined by the standard method by the titrimetric method. The value of the period of induction of oil oxidation is determined graphically from the growth curves of peroxide numbers. The content of tocopherols in oils is determined by spectrophotometric method. The content of sesamol and sesamoline in oils is determined by the colorimetric method. The oxidative stability of oils is determined using the accelerated “active oxygen” method.
To plan the experiment and process the data, mathematical methods are applied using the software Microsoft Office Excel 2003.
The oxidation stability of blended oils (a mixture of sesame, high oleic, sunflower and corn refined oils) and its components is investigated. Blended oil has a lower oxidative stability than sesame oil, but higher than corn and high oleic sunflower. The oxidative stability of the blend is enhanced by the antioxidant content of sesamol and sesamoline. The content of the above antioxidants, as well as the amount of tocopherols, is studied in blended oils. The oxidation stability of the obtained solution of provitamin A in blended oils is investigated. The period of induction of oxidation of blended oils with the addition of 0.2 % β-carotene increases by 1.3 times compared with the period of induction of the original blended oil. Blended long-life oil is recommended to be used to stabilize fat-soluble biologically active compounds
THE ROLE OF LAND-USE PLANNING FOR ORGANIZE THE BALANCED TERRITORIAL DEVELOPMENT WITHIN THE UNITED TERRITORIAL COMMUNITIES
Get PDFIt is a well-known fact that sustainable land use can contribute the formation and maintenance of balanced territorial development. At the same time in scientific publications too little attention is paid to the consideration of land-use planning as an indispensable elementary component of sustainable land use.
The aim of this article is to highlight is the importance of land-use planning for balanced territorial development within united territorial communities, mainly by analyzing existing land use and justification recommendations for optimizing land use on a balanced development basis.
Land-use planning involves the creation of documentation, including planning and mapping materials, which regulates of land use process within certain administrative unit. In Ukraine, such materials are first of all, a scheme (plan) of land-use certain territorial community, which is compiled on a scale of 1:10000 and contains the current state of land use within the territory of the village council (united territorial community), environmental measures and information on land-use planning for the appropriate perspective. So, the main direction of implementation the ideas of balanced territorial development for the certain administrative unit is the creating a plan for its land-use planning based on the principles of optimization landscape systems on the balanced development basis.
On this basis, let’s analyze the current state of land use the Nedogarkiv United Territorial Community and justify recommendations for optimizing land use on a balanced development basis.
On a whole, land-use planning is essential for the organization of balanced (sustainable) development of the territory, since the documental status of all created materials indicates that they are mandatory for all landowners and land users. The only disadvantage is the complete dependence of land-use planning on the legislative framework certain country, which complicates the offering of uniform methods of its application for several states or individual regions of the world
INVESTIGATION OF THE IMPORTANCE OF STARUNIA PALEONTOLOGICAL LOCATION OF THE PLEISTOCENE FAUNA OF THE RHINOCEROSES AND THE MAMMOTHS FOR QUATERNARY GEOLOGY
Get PDFThe first finds of mummified carcasses of the hairy rhino, mammoth, horse, roe deer and other animals were carried out at a depth of 12 m when passing the mines for the production of ozokerite near the village. The expedition of the Academy of Skill from Krakow, when passing a mine at a depth of 17 m, found the remains of 3 more hairy rhinos. There were also numerous bones of small vertebrates (rodents), artichokes, numerous insects, beetles, parasitic worms, slag, butterflies, spiders, snails, vascular plants, seeds and branches of dwarf birch, alder, and other representatives of tundra flora. After the earthquake in the Vrancha Mountains (Romania), the first and still unique mud volcano in the Carpathians, which gave the Starunia paleontological location a new "sound", arose on the ozokerite deposit.
An important result was the discovery of the most desirable area, where the remains of giant mammals and even the Cro-Magnon Pleistocene could still be found at the depths. All the numerous interdisciplinary traces of Polish and Ukrainian scientists confirm the uniqueness of Starunia on a global scale, requiring the preservation and further study of paleontological finds and the only mud volcano in the Carpathians. Such findings can only be made by organizing the Starunia geodynamic ground International Ecological and Tourist Center «Geopark Ice Age»
