Numerical Research

From the theory of aerohydrodynamics it is known that the design of hydraulic nozzles and the modes of their operation determine the nature of the distribution of droplets in space and the efficiency of the process. The subject of the research is the characteristics of the distribution quality of the liquid reagent, namely, the speed of dropping of droplets from the disk and the radius of the treatment zone formed by flying droplets on the coating. The question of the dispersion of the spray torch of a low-viscosity liquid, its role in the formation of the basic kinematic characteristics of moving drops, is considered. The article provides a numerical calculation and analysis of the effect of the dispersion of droplets of a distributed liquid (reagent) on the rate of dropping of droplets from a rotating disk and on the radius of the coating treatment zone. For research, two values of nozzle nozzle openings and a wide range of variation in the diameters of reagent droplets were selected. Based on the mathematical models previously developed by the authors of the process of dropping droplets from the nozzle and the movement of droplets in the air, implemented as part of a software product, the velocity of dropping of droplets from the nozzle nozzle and the rate of dropping of droplets from the disk at a given pressure were calculated. A cycle of calculations of the radius of the coating treatment zone was carried out with varying work and geometric characteristics of hydraulic equipment, providing high-quality and cost-effective implementation of the anti-icing reagent distribution process.

Lactate is known to be an indicator of neurological impairment during aortic aneurysm surgery. It is suggested that analysis of cerebrospinal fluid (CSF) removed during such surgery could provide useful information in this regard. Medical professionals find the prospect of online detection of such analytes exciting, as current practice is time consuming and leads to multiple invasive procedures. Advancing from the current laboratory based analysis techniques to online methods could provide the basis for improved treatment regimes, better quality of care, and enhanced resource efficiency within hospitals. Accordingly, this article considers the use of a low power microwave sensor to detect varying lactate concentrations. Microwave sensors provide a rapid non-invasive method of material analysis, which is robust, cost-effective, and has huge potential for a wide range of biomedical applications.

A substantial portion of usability work involves the coordinated collection of data by a team of specialists with varied backgrounds, employing multiple collection methods, and observing users with a wide range of skills, work contexts, goals, and responsibilities. The desired result is an improved system design, and the means to that end are the successful detection of, and reaction to, real deficiencies in system usability that severely impact the quality of experience for a range of users. In the context of user-centered design processes, valid and reliable data from a representative user sample is simply not enough. High-quality usability data is not just representative of reality. It is useful. It is persuasive in the eyes of the right stakeholders. It results in verifiable improvements to the system for which it is intended to represent a deficiency. The data must be efficiently and effectively translated into development action items with appropriate priority levels, and it must result in effective work products downstream, leading to cost-effective design changes. The remainder of this article (a) briefly reviews basic usability data collection concepts, (b) examines the dimensions that make up high-quality usability data, and (c) suggests future trends in usability data quality research.

The paper presents an analysis of the quality of soft wheat grown in different soil and climatic conditions of the Russian Federation and having a wide range of quality indicators (the amount of gluten - from 15.3 to 29.4%, the quality of gluten - from 29 to 84 units. IIR, falling number - from 134 to 475 sec). Revealed significant differences in the quality of modern Russian wheat from the wheat of the late XX century. The interrelationships of indicators of quality of grain, flour obtained from it, rheological properties of dough with indicators of quality of bread on a modern instrument base using an alveograph, valorigraph and mixolab have been established. The study of the rheological properties of the dough on the mixolab was carried out in the classical "Chopin Wheat +" mode. According to the profiler parameters (radial diagram), it was found that the analyze grain was characterized by increased rates of starch retrogradation, which characterizes the carbohydrate-amylase complex of flour, a high water absorption index, and increased amylolytic activity; low viscosity and gluten +. To differentiate the strength of wheat, a test laboratory baking of bread was carried out using two methods - the remix method and the reduced-remix method, which showed that the most stable relationships were revealed when baking bread with the remix method. When baking with the abbreviated method, higher indicators of bread quality were obtained, but there are fewer stable relationships, moreover, both for wheat containing less than 25% gluten and more than 25%.

With the advent of modern technology, its essential to avail the latest consumer trends to get maximum efficient results in the context of a globalized market. More attention is paid to the consumption of manufactured goods and everyday items. Much less attention is paid to the service sector, in particular medical, recreational and physical. There is also a lack of application of mathematically grounded, computer methods and models for such modelling. We proposeda fuzzy based test metrics for a cosmetology paradigm (FTMCP) as tasks of multi-criteria decision making on a variety of alternatives. The Specific features of cosmetology services, marketing, communication components are determined. A computer model in the Fuzzy Tech, specialized software product for computer fuzzy modelling, was developed. Integrated assessments for cosmetic institutions have been calculated. The results are analyzed and recommendations for improving the quality of cosmetology service, websites of cosmetology institutions, are suggested. The principles of the proposed approach, the described fuzzy model and its computer implementation can be applied to a wide range of tasks of multi criteria assessment of customer service in various social fields - retail stores, medicine, culture, health, physical education and training, public catering, other household and domestic services.

Ultrasonic Thickness

Ultrasonic thickness gauges are easy to operate and reliable, and can be used to measure a wide range of thicknesses and inspect all engineering materials. Supplementing the simple ultrasonic thickness gauges that present results in either a digital readout or as an A-scan with systems that enable correlating the measured values to their positions on the inspected surface to produce a two-dimensional (2D) thickness representation can extend their benefits and provide a cost-effective alternative to expensive advanced C-scan machines. In previous work, the authors introduced a system for the positioning and mapping of the values measured by the ultrasonic thickness gauges and flaw detectors (Tesfaye et al. 2019). The system is an alternative to the systems that use mechanical scanners, encoders, and sophisticated UT machines. It used a camera to record the probe’s movement and a projected laser grid obtained by a laser pattern generator to locate the probe on the inspected surface. In this paper, a novel system is proposed to be applied to flat surfaces, in addition to overcoming the other limitations posed due to the use of the laser projection. The proposed system uses two video cameras, one to monitor the probe’s movement on the inspected surface and the other to capture the corresponding digital readout of the thickness gauge. The acquired images of the probe’s position and thickness gauge readout are processed to plot the measured data in a 2D color-coded map. The system is meant to be simpler and more effective than the previous development.

The construction and selection of a suitable bijective function, that is, substitution, is now becoming an important applied task, particularly for building block encryption systems. Many articles have suggested using different approaches to determining the quality of substitution, but most of them are highly computationally complex. The solution of this problem will significantly expand the range of methods for constructing and analyzing scheme in information protection systems. The purpose of research is to find easily measurable characteristics of substitutions, allowing to evaluate their quality, and also measures of the proximity of a particular substitutions to a random one, or its distance from it. For this purpose, several characteristics were proposed in this work: difference and polynomial, and their mathematical expectation was found, as well as variance for the difference characteristic. This allows us to make a conclusion about its quality by comparing the result of calculating the characteristic for a particular substitution with the calculated mathematical expectation. From a computational point of view, the thesises of the article are of exceptional interest due to the simplicity of the algorithm for quantifying the quality of bijective function substitutions. By its nature, the operation of calculating the difference characteristic carries out a simple summation of integer terms in a fixed and small range. Such an operation, both in the modern and in the prospective element base, is embedded in the logic of a wide range of functional elements, especially when implementing computational actions in the optical range, or on other carriers related to the field of nanotechnology.

Software systems are any software product or applications that support business domains such as Manufacturing,Aviation, Health care, insurance and so on.Software quality is a means of measuring how software is designed and how well the software conforms to that design. Some of the variables that we are looking for software quality are Correctness, Product quality, Scalability, Completeness and Absence of bugs, However the quality standard that was used from one organization is different from other for this reason it is better to apply the software metrics to measure the quality of software. Attributes that we gathered from source code through software metrics can be an input for software defect predictor. Software defect are an error that are introduced by software developer and stakeholders. Finally, in this study we discovered the application of machine learning on software defect that we gathered from the previous research works.
