A computational method for the automated formation of a typical form digital image investigated objects on series frames has been developed. Due to imperfection mounting cameras, as well their mounts, immobility at shooting during exposure time can be disturbed, which leads "blurred" images various forms. such inaccuracies in tracking frames, even one series, vary from frame frame. This fact difference standard significantly complicates execution processing tasks. In order simplify...

Safety of transfer and reception various data over the internet can be accompanied by a presence harmful components in passed content. The phishing attack is one versions such components. Thus it important to know relationship between phishes verified as valid suspected Submitted. This necessary for forecast. To solve this problem, we use wavelet analysis time series which represent submitted. We are considering change Hurst indicator; analyse spectrum energy. allows you identify features...

Analysis of economic dynamics is an important task. Such analysis makes it possible to identify potential threats for development, analyze risks. This security and management. In order conduct a study dynamics, infocommunication systems can be used. For this study, necessary choose mathematical methods models. We consider wavelet ideology analyzing security. suggest using coherence build portraits dynamics. The results are given on the example real data banking sector economy Ukraine.

The object of this study is the process filtering astronomical frames that contain images potential objects in Solar System. To contour image each such and recognize it contrast with background frame, necessary to filter image. Most often, a variety high-pass filters are used determine high-frequency component image, which can be removed as coarse-grained component. Any aimed at increasing signal-to-noise ratio reducing dynamic range However, quite resource- time-consuming. This especially...

Image processing is used in many fields of knowledge; because it allows to automate processes get more information about the object being studied. techniques are and varied. Wavelet analysis one such techniques. Among various methods approaches wavelet we distinguish ideology multiresolution analysis. The essence this perform decomposition on test data subsequent relevant factors (the coefficients). An important aspect consideration properties coefficients. Based this, have examined...

Processing and analysis of data sequences using wavelet-decomposition subsequent the all relevant coefficients such decomposition is one strong methods to study various processes phenomena. The key point sequence lies in concept Hurst exponent. This due fact that exponent gives an indication complexity dynamics correlation structure any given time series taking into consideration importance estimation for analysis. There are approaches find with varying degrees accuracy complexity....

The foreign exchange market plays an important role in the formation and development of financial markets. This is particular importance for emerging economies. To understand trends (to develop a strategy its development), it necessary to analyze historical data. It also use different methods carry out this analysis. Based on this, paper analyzes Ukraine period 2014-2018. For analysis, wavelet coherence methodology used. made possible assess Ukraine.

Basic elements of casting process and its main stages are considered. Features time characteristics for production plastic products investigated. The in the methodology optimization given. proposed allows to increase productivity optimize products, taking into account preservation quality which is achieved by reducing cycle. At same considered considers plunger forward backward, "course" nozzle time, extraction product from matrix during products.

We applied the wavelet methodology for our earlier published research work of chaotic behavior so called multiplicity fluctuations secondary charged particles produced during nucleus-nucleus (A-A) collisions at an energy order ≈ 409 GeV in a new fashion. illustrated coherency relation above said data pions different phase spaces such as: η-space, φ-space (in one dimension) and ηφ-space two dimensions) respectively. have shown changes coherence when there are values parameters “q” “p”....

The paper demonstrates the possibilities of a vector approach for calculating stoichiometric coefficients chemical equations using example black powder. An is proposed selecting and limiting intermediate interactions between reactants determining final products. It shown that even small number components can lead to large Using real calculations, relationship possible shown. A method all in reaction system an arbitrary ratio components, which allows obtaining reactions, composition fixed set...

An attempt has been made to apply the wavelet methodology for study of results chaotic behavior multiparticle production in relativistic heavy ion collisions. We reviewed data that describes collisions case η-space 1-D phase space variable. compared experimental and UrQMD using coherency. discussed comparison.

Financial markets are an important structural element of the economy. These make it possible to mobilize and reallocate financial resources. However, such a process is constantly under threat various risks. To prevent minimize risks, necessary use comprehensive procedure for analyzing conditions occurrence this end, we examined interrelationship stochastic frontier analysis wavelet ideology. We emphasize link between technical efficiency For advanced risk, apparatus theory wavelets. The...

У теперішні важки часи для української економіки актуальним є впровадження технології реверсного інжинірингу. За допомогою 3D-сканування створюється цифрова модель різних об’єктів. Реверс-інжиніринг використовується в галузях промисловості. Автоматизація процесу інжинірингу промислового об’єкта потребує наукового вирішення низки завдань: обґрунтування вибору ефективного методу інжинірингу; 3D-сканера з урахуванням особливостей об’єкта; програмного забезпечення та апаратного забезпечення....
