Perancangan Aplikasi Kids Memory Game Berbasis Android

Child growth is the most important moment for a child. Children who are still young must be equipped with useful education so that later it will be useful when the child is growing up. Children's memory is very important to be trained as a child because with the process of memory training it can train the child to be fast in learning something good whether it's a lesson or other general matters. In practice, the learning process to train the child's memory is still done manually, namely by picture books, this is less interesting for the child because children prefer to play while learning. Besides the existing textbooks are quite boring because there are no games or sound effects that attract the child's interest to learn. Therefore, the above problems will be designed an educational game that trains children's memory with the concept of play. The results of this study are in the form of an educational game called Kids Memory Game which is used as a media for children's education and media to train children's memory.

General Relativity solutions with stealth scalar hair in quadratic higher-order scalar-tensor theories

We explore General Relativity solutions with stealth scalar hair in general quadratic higher-order scalar-tensor theories. Adopting the assumption that the scalar field has a constant kinetic term, we derive in a fully covariant manner a set of conditions under which the Euler-Lagrange equations allow General Relativity solutions as exact solutions in the presence of a general matter component minimally coupled to gravity. The scalar field possesses a nontrivial profile, which can be obtained by integrating the condition of constant kinetic term for each metric solution. We demonstrate the construction of the scalar field profile for several cases including the Kerr-Newman-de Sitter spacetime as a general black hole solution characterized by mass, charge, and angular momentum in the presence of a cosmological constant. We also show that asymptotically anti-de Sitter spacetimes cannot support nontrivial scalar hair.

Covid-19 communication management in Spain: Exploring the effect of information-seeking behavior and message reception in public’s evaluation

The World Health Organization (2011) has emphasized communication as one of the biggest challenges and places risk communication among the essential competencies required to tackle a pandemic. In light of the Covid-19 crisis, the aim of this paper is to assess how information forms and sources influence the public’s information-seeking behaviors, and the perception of government’s crisis response strategies during the pandemic. An online survey was conducted between March 14 and April 14, 2020, the first four weeks after the declaration of the State of Alarm in Spain. The online questionnaire included questions regarding information-seeking behavior, trust in different sources and channels, perception of government communication management, message retention, and demographic questions. Findings show a synchronous use of multiple media and platforms in line with channel complementarity theory. Three of the four most used information channels are considered mainstream news media. However, the second source of information is WhatsApp. People who relied more on the mainstream news media for Covid-19 information are generally most likely to express positive opinions of the government’s communication strategy. Findings also show that people less able to make correct attributions of governmental information were the most critical of the government’s crisis response. Finally, trust in public authorities’ decreases as the crisis evolves as a general matter. It is specially truth for the WHO, but there is also a striking exemption for local governments. Implications for theory and empirical research and recommendations and new issues to address are identified and discussed.

Ethics in compulsory education – Human dignity, rights and social justice in five contexts

What children learn through their ethics and values education in school is of crucial societal relevance and is directed by school curricula. As curricula vary between countries, an international comparison is of interest. The aim of this study was to compare curricula to reveal variations in how matters of social justice were described in curricular texts, with a special focus on class, gender and race. Curricula from five different contexts were compared: Namibia; South Africa; California State, United States of America; Province of Québec, Canada; and Sweden. This provided the study, originating in Sweden, with crucial comparative material from outside Europe. The studied curricula were systematically searched for the importance and significance of the terms ‘poverty/poor’, ‘gender’, ‘equity’, ‘equality’, ‘justice’, ‘race’, ‘racism’, ‘human dignity/rights’, ‘equal value’ and Ubuntu. Methodologically, this represented a qualitative content analysis approach with a research interest in intersectionality, that is, in how matters of class, gender and race intersect. The study showed considerable variation between the curricular formulations from the five contexts. For example, texts from California and Québec emphasised equality as a general matter and less as one of intersectionality, compared to Namibia and South Africa as well as Sweden. In general, human rights were emphasised, but human dignity less so. For future curricular development towards education as a global common good, matters of social justice, including sustainability, need critical monitoring. The aspects of intersectionality such as class, gender and race are thus crucial, as is the inclusion of an integrated, participatory view on students’ ethical competence.

Comparison of bioaccessibility methods in spiked and field Hg-contaminated soils

Estimating bioaccessible content of mercury in soils is essential in evaluating risks that contaminated soils pose. In this study, soil samples spiked with HgCl2 through adsorption were used to test the effects of liming, soil organic matter, soil depth, and Hg concentration on the following bioaccessibility tests: dilute nitric acid at room temperature, dilute nitric acid at body temperature, Simplified Bioaccessibility Extraction Test (SBET) method, and gastric phase of the In vitro Gastrointestinal (IVG) protocol. Soil and sediment samples from Descoberto, Minas Gerais (Brazil), a city with a well-known record of Hg contamination from artisanal mining, were subjected to these bioaccessibility tests for the first time, and the different methods of estimating bioaccessible content were compared. Bioaccessible fractions in spiked samples ranged from 10% to 60%, and this high bioaccessibility was due to the highly soluble species of Hg and the short time under adsorption. In general, clay and organic matter decreased bioaccessible content. Although the soil in Descoberto is undoubtedly polluted, mercury bioaccessibility in that area is low. In general, dilute nitric acid estimated higher bioaccessible content in soil samples, whereas the SBET method estimated higher bioaccessible content in sediment samples. In multivariate analysis, two groups of bioaccessibility tests arise: one with the two nitric acid tests, and the other with SBET and the gastric phase of the IVG protocol. The addition of pepsin and glycine in the last two tests suggests a more reliable test for assessing mercury bioaccessibility.

Efficient solution of the anisotropic spherically aligned axisymmetric Jeans equations of stellar hydrodynamics for galactic dynamics

ABSTRACTI present a flexible solution for the axisymmetric Jeans equations of stellar hydrodynamics under the assumption of an anisotropic (three-integral) velocity ellipsoid aligned with the spherical polar coordinate system. I describe and test a robust and efficient algorithm for its numerical computation. I outline the evaluation of the intrinsic velocity moments and the projection of all first and second velocity moments, including both the line-of-sight velocities and the proper motions. This spherically aligned Jeans anisotropic modelling (JAMsph) method can describe in detail the photometry and kinematics of real galaxies. It allows for a spatially varying anisotropy, or stellar mass-to-light ratio gradients, as well as for the inclusion of general dark matter distributions and supermassive black holes. The JAMsph method complements my previously derived cylindrically aligned JAMcyl and spherical Jeans solutions, which I also summarize in this paper. Comparisons between results obtained with either JAMsph or JAMcyl can be used to assess the robustness of inferred dynamical quantities. As an illustration, I modelled the ATLAS3D sample of 260 early-type galaxies with high-quality integral-field spectroscopy, using both methods. I found that they provide statistically indistinguishable total density logarithmic slopes. This may explain the previously reported success of the JAM method in recovering density profiles of real or simulated galaxies. A reference software implementation of JAMsph is included in the publicly available jam software package.

CN-China: Revised runoff curve number by using rainfall-runoff events data in China

The curve number (CN) method developed by the United States Department of Agriculture (USDA) in 1954 is the most common adopted method to estimate surface runoff. For years, applicability of the CN method is a conundrum when implementing to other countries. Specifically, countries with more complex natural environment may require more dedicated adjustments. Therefore, the current CN look-up table provided by USDA might not be appropriate and could be questionable to be applied directly to regions elsewhere. Some studies have been conducted to modify CN values according to specified natural characteristics in scattered regions of mainland China. However, an integral and representative work is still not available to address potential concerns in general matters. In this study, a large set of rainfall-runoff monitoring data were collected to adjust CN values in 55 study sites across China. The results showed that the revised CN values are largely different from CN look-up table provided by USDA, which would lead to huge errors in runoff estimation. In this study, the revised CN (dubbed CN-China) provides better reference guidelines that are suitable for most natural conditions in China. In addition, scientists and engineers from other parts of the world can take advantage of the proposed work to enhance the quality of future programs related to surface runoff estimation.

Revising the Federal Rules of Civil Procedure: Carving Out a More Active Role for Congress

The adoption of the Federal Rules of Civil Procedure was a major victory for progressives in the United States. The Rule made access to justice less about one’s ability to hire a high-priced lawyer and more about the swift determination of the merits of the dispute between the parties. Despite efforts of some business interests to alter the rules, by most accounts, by most accounts, the Rules have been successful. But occasional conflicts between the application of federal vs. state law in diversity actions create hard policy choices. As a rule, in diversity actions, federal courts must apply state substantive law and federal procedural law. Of course, drawing the line between substance and procedure often presents courts with difficult vertical choice of law problems. At time, the application of a federal rule may impair significant state substantive interests. However, allowing litigants too easily to challenge the application of a federal rule conflicts with the overall goal of the Rules, which should advance the “just, speedy, and inexpensive determination of every action and proceeding.” Satellite litigation to determine whether a federal or state rule applies cuts against the policy of inexpensive and uniform application of the federal rules. Two recent conflicts between federal and state law present challenges in the application of Court precedent. In Twombly v. Bell Atlantic Corp. and then in Ashcroft v. Iqbal, the Supreme Court rewrote F.R.C.P. 8(a)(2)’s liberal pleading standard, making access to court more difficult for many plaintiffs. Some states have rejected those holdings and adhere to the more liberal standard reflected in the adoption of the Rules. And yet, plaintiffs face more stringent pleading requirements when defendants can remove actions from state to federal court. Application of federal law impairs an important state substantive policy: liberal access to justice. The second conflict that has divided federal court is whether a federal court must apply federal pleading and summary judgment rules in defamation cases when the state would apply special anti-SLAPP provisions. Those provisions make dismissal of certain defamation actions easier than in cases that do not involve First Amendment speech challenges. Again, at issue is the conflict between the uniform application of the relevant federal procedural rules and an important state substantive policy, the advancement of free speech. These two areas present special problems. Generally, federal procedural rules should apply. The two problems discussed in this article present special problems where application of federal law impairs important state interest. Normally, one could expect the Court in conjunction with the Judicial Conference’s Advisory Committee on Civil Rules to revise the rules. Under Chief Justice John Roberts’ leadership, the conference’s members are now “ideologically predisposed to think like Federalist Society members, demographically predisposed to think like elite white males, or experientially predisposed to think like corporate defense lawyers.” As a result, progressive reforms of the Rules are not likely to originate with the Court and the Advisory Committee. As a general matter, Congress should take a limited role in reforming the Rules. At the same time, Congress has created special rules in the past. For example, it did so for overtly pro-business reasons in its adoption of special pleading standards that were part of the 2005 Class Action Fairness Act. This article argues for Congress to act to modify the F.R.C.P. in two specific areas: one would clarify that more generous state pleading rules must apply to actions removed from state courts in diversity actions, the other would make clear that state pleading and summary judgment rules should apply when the controlling state law includes anti-SLAPP provisions.

The geography of agriculture participation and food security in a small and a medium-sized city in Ghana

The debate about the contribution of urban agriculture to urban household food security has not considered the possible differential effects by geography of production activities, focusing either on urban household’s participation in agriculture irrespective of where the activity takes place, or restricting participation to production within urban and peri-urban areas, or more narrowly, production within build-up urban spaces. Using a sample of 2004 households in a small and a medium-sized city in Ghana, this article contributes by disentangling urban household’s participation in agriculture by geography of production activities and the implications for the food security of urban households. We find no evidence from our sample that participation in agriculture in general matters for the food security of urban households. However, urbanites who produced food in both urban and rural areas had better food security in the medium-sized city.

Relaxed hypermultiplet in four dimensional N=2 conformal supergravity

Superconformal matter multiplets play a crucial role in the construction of Poincare supergravity invariants. Off-shell multiplets allow for construction of general matter couplings in supergravity. In Nucl. Phys. B214 (1983) 519-531, relaxed hypermultiplet was constructed in rigid supersymmetry which on coupling with the real scalar multiplet allowed for an off-shell formulation of the rigid hypermultiplet. In this paper, we extend the relaxed hypermultiplet to conformal supergravity. For consistency with the superconformal algebra, we find that the fields have to be allowed to transform in a non-canonical way under SU(2) symmetry. We find suitable field redefinitions to obtain fields which are irreducible representations of SU(2) R-symmetry and present the full non-linear transformation rule.

White matter basis for the hub-and-spoke semantic representation: evidence from semantic dementia.

The hub-and-spoke semantic representation theory posits that semantic knowledge is processed in a neural network, which contains an amodal hub, the sensorimotor modality-specific regions, and the connections between them. The exact neural basis of the hub, regions and connectivity remains unclear. Semantic dementia could be an ideal lesion model to construct the semantic network as this disease presents both amodal and modality-specific semantic processing (e.g. colour) deficits. The goal of the present study was to identify, using an unbiased data-driven approach, the semantic hub and its general and modality-specific semantic white matter connections by investigating the relationship between the lesion degree of the network and the severity of semantic deficits in 33 patients with semantic dementia. Data of diffusion-weighted imaging and behavioural performance in processing knowledge of general semantic and six sensorimotor modalities (i.e. object form, colour, motion, sound, manipulation and function) were collected from each subject. Specifically, to identify the semantic hub, we mapped the white matter nodal degree value (a graph theoretical index) of the 90 regions in the automated anatomical labelling atlas with the general semantic abilities of the patients. Of the regions, only the left fusiform gyrus was identified as the hub because its structural connectivity strength (i.e. nodal degree value) could significantly predict the general semantic processing of the patients. To identify the general and modality-specific semantic connections of the semantic hub, we separately correlated the white matter integrity values of each tract connected with the left fusiform gyrus, with the performance for general semantic processing and each of six semantic modality processing. The results showed that the hub region worked in concert with nine other regions in the semantic memory network for general semantic processing. Moreover, the connection between the hub and the left calcarine was associated with colour-specific semantic processing. The observed effects could not be accounted for by potential confounding variables (e.g. total grey matter volume, regional grey matter volume and performance on non-semantic control tasks). Our findings refine the neuroanatomical structure of the semantic network and underline the critical role of the left fusiform gyrus and its connectivity in the network.

Are Experts (News)Worthy? Balance, Conflict, and Mass Media Coverage of Expert Consensus

ABSTRACT Overlooked in analyses of why the public often rejects expert consensus is the role of the news media. News coverage of expert consensus on general matters of policy is likely limited as a result of journalists’ emphasis in news production on novelty and drama at the expense of thematic context. News content is also biased toward balance and conflict, which may weaken the persuasiveness of expert consensus. This study presents an automated and manual analysis of over 280,000 news stories on 10 issues where there are important elements of agreement among scientists or economists. The analyses show that news content typically emphasizes arguments aligned with positions of expert consensus, rather than providing balance, and only occasionally cites contrarian experts. More troubling is that expert messages related to important areas of agreement are infrequent even in relevant news content, and cues signaling the existence of consensus are rarer still.

Formation of corporate culture as a basis for increasing the enterprise competitiveness

Actuality of research theme. Assessing the competitiveness of an enterprise is a complex multifactorial task, which boils down to identifying the most significant numerical indicators of competitiveness and their integration. The need to aggregate all indicators is due to the fact that the object of modeling (the effective functioning of the enterprise) requires not only generalizing characteristics, but also the ordering of its individual elements according to certain properties and principles. The problem of forming a sound corporate culture as a basis for increasing competitiveness of the enterprise becomes especially acute. Problem statement. Nowadays conditions business environment require introduction of a sound system for assessing the effectiveness of corporate culture and establishing a close relationship with the competitiveness of the enterprise. Analysis of the last researches and publications. Almost all researchers of the theory of assessment and management of competitiveness are engaged in the search for a capable management system that would facilitate the rapid response of the business entity to change the external and internal business environment, adaptation to new conditions. Despite considerable work, there remain problems requiring particular scientific analysis. In particular, insufficient attention is paid to exploring the soundness of corporate culture as a basis for increasing competitiveness of the enterprises of all forms of ownership. Uninvestigated parts of general matters defining. Not enough-researched and unpublished parts in periodicals issues remain related optimal methodological approach to assess the level of competitiveness of the enterprise, taking into account the formed corporate culture and the level of competitiveness of labor resources. The primary purpose of the study comprises to identify the peculiarities of corporate culture formation as a basis for increasing competitiveness of the enterprises of all forms of ownership. The methodological basis of the research was the scientific works of Ukrainian and foreign scientists, leading experts, statistical and analytical materials of state authorities. Results. The peculiarities of definition and formation of corporate culture are investigated. The level of corporate culture at the enterprise is assessmented. It has been revealed that the lack of a sound methodological approach to employee rating and appropriate means of motivation for professional development can lead to the loss of existing intellectual potential and competitive positions in the market services in general. The expediency of using the methodology of assessment of the efficiency of management of the enterprise based on the use of taxonomic analysis is substantiated. The expediency of forming an effective corporate culture as a basis for increasing competitiveness of the enterprises of all forms of ownership is substantiated. The field of application of results. The results of the study can be used by all stakeholders, including public authorities and local self-government, leading enterprises in the region. Conclusions. The leadership of domestic enterprises should ensure the formation and implementation of an effective corporate culture with a certain set of material and spiritual values, rules of behavior of employees.

Zmiany społeczno-polityczne przeprowadzone przez Ministerstwo Administracji Publicznej w latach 1944–1950 dotyczące spraw Kościołów i związków wyznaniowych w Polsce

The Ministry of Public Administration was established pursuant to the Act of 31 December 1944 on the appointment of the Interim Government of the Republic of Poland. The matters arising from the relations between the State and the Churches and religious denominations were handled by Department V, which in 1946 consisted of two sections addressing Christian and non-Christian denominations, respectively. The Socio-Political Departments in the Provincial Offices, which employed officials responsible for matters relating to religious denominations, were subordinate to Department V. The same held true in Starostwa Powiatowe [County Offices]. In 1947, Department V was divided into three units addressing matters of the Catholic Church, Christian Denominations and Non-Christian denominations, respectively, and one year later still one more department, i.e. the Department of General Matters, was established. Since 1947 matters relating to religious denominations fell within the competences of Department IV. The Department of Religious Denominations in the Ministry of Public Administration from its beginnings was responsible for shaping the policy of the State towards religious denominations. The aforementioned policy was supposed to be concordant with the directives and principles of the communist party. The socio-political reforms conducted by the Ministry of Public Administration in relation to the Churches and religious associations were one of the means of repression, which within the years 1944-1950 was in its initial phase based on the trial-and-error method. However, it was the cooperation of the Ministry with Urząd Bezpieczeństwa Publicznego [Public Security Office], and later the establishment of Urząd ds. Wyznań [Office in charge of Religious Denominations] in 1950 which changed and regulated actions of the communist authorities towards the Churches and religious associations in Poland regarding the matters concerning the relations between the State and the Church and religious associations. From then on the competences to date of Department IV of the Ministry of Public Administration were transferred onto the Office in charge of Religious Denominations.

Organo-mineral complexes protect condensed organic matter as revealed by benzene-polycarboxylic acids

Condensed organic matters (COM) with black carbon-like structures are considered as long-term carbon sinks because of their high stability. It is difficult to distinguish COM from general organic matter by conventional chemical analysis, thus the contribution by and interaction mechanisms of organo-mineral complexes in COM stabilization are unclear and generally neglected. Molecular markers related to black carbon-like structures, such as benzene polycarboxylic acids (BPCAs), are promising tools for the qualitative and quantitative analysis of COM. In this study, one natural soil and two cultivated soils with 25 y- or 55 y-tillage activities were collected and the distribution characteristics of BPCAs were detected. All the investigated soils showed similar BPCA distribution pattern, and over 60% of BPCAs were detected in clay fraction. The extractable BPCA contents were substantially increased after mineral removal. The ratios of BPCA contents before and after mineral removal indicate the extent of COM-mineral particle interactions, and our results suggested that up to 73% COM were protected by mineral particles, and more stronger interactions were noted on clay than on silt. The initial cultivation dramatically decreased COM-clay interactions, and this interaction was recovered only slowly after 55-y cultivation. Kaolinite and muscovite are important for COM protection. But a possible negative correlation between BPCAs and reactive iron oxides of the cultivated soils suggested that iron may promote COM degradation when disturbed by tillage activities. This study provided a new angle to study the stabilization of COM and emphasized the importance of organo-mineral complexes for COM stabilization.

Machine Learning, Big Data and the Regulation of Consumer Credit Markets: The Case of Algorithmic Credit Scoring

Recent advances in machine learning (ML) and Big Data techniques have facilitated the development of more sophisticated, automated consumer credit scoring models — a trend referred to as 'algorithmic credit scoring' in recognition of the increasing reliance on computer (particularly ML) algorithms for credit scoring. This chapter, which forms part of the 2018 collection of short essays 'Autonomous Systems and the Law', examines the rise of algorithmic credit scoring, and considers its implications for the regulation of consumer creditworthiness assessment and consumer credit markets more broadly. The chapter argues that algorithmic credit scoring, and the Big Data and ML technologies underlying it, offer both benefits and risks for consumer credit markets. On the one hand, it could increase allocative efficiency and distributional fairness in these markets, by widening access to, and lowering the cost of, credit, particularly for 'thin-file' and 'no-file' consumers. On the other hand, algorithmic credit scoring could undermine distributional fairness and efficiency, by perpetuating discrimination in lending against certain groups and by enabling the more effective exploitation of borrowers. The chapter considers how consumer financial regulation should respond to these risks, focusing on the UK/EU regulatory framework. As a general matter, it argues that the broadly principles and conduct-based approach of UK consumer credit regulation provides the flexibility necessary for regulators and market participants to respond dynamically to these risks. However, this approach could be enhanced through the introduction of more robust product oversight and governance requirements for firms in relation to their use of ML systems and processes. Supervisory authorities could also themselves make greater use of ML and Big Data techniques in order to strengthen the supervision of consumer credit firms. Finally, the chapter notes that cross-sectoral data protection regulation, recently updated in the EU under the GDPR, offers an important avenue to mitigate risks to consumers arising from the use of their personal data. However, further guidance is needed on the application and scope of this regime in the consumer financial context.

Detecting Florida's Gerrymander: A Lesson in Putting First Things First

ObjectiveWe show that Florida's post‐2010 congressional districts were an ex ante knowable gerrymander, which, if diagnosed as a factual matter before enactment, would have avoided both the 2012 and 2014 harm and the state's unnecessarily burdensome reliance on a showing of intent.MethodWe recount the legal focus on intent, apply the McDonald‐Best equal vote weight effects test standard to the Florida facts, and use more than 25,000 simulated districting plans to check on whether there was a gerrymander effect.ResultsWe find a pro‐Republican gerrymander effect could have been detected in advance of enacting Florida's redistricting plan.ConclusionIn specific reference to Florida, we conclude the enacted districts could have been identified as a gerrymander beforehand, allowing court proceedings to move expeditiously and with a clear focus. As a general matter, we conclude a comprehensive approach to gerrymandering is best served by following a two‐part prescription: (1) set an effect standard for identifying a gerrymander and (2) know the intent by checking the facts against the standard.

Remarks by Sean D. Murphy

Our conversation might begin by looking backward a bit. The human rights movement from 1945 onward has been one of the signature accomplishments of the field of international law, one that refocused our attention from a largely interstate system to a system where the individual moved in from the periphery to the center. Human rights champions point to numerous landmark treaties, numerous institutions, and the rise of NGOs as a critical vehicle for developing and monitoring human rights rules. Yet others look at the international human right system and still see the state as overly central, tolerating and paying lip service to human rights, but too easily discarding them when they prove to be inconvenient. The persistence of racism comes to mind. As a general matter, how would you assess the strengths and weaknesses of the system that was built essentially during your lifetime?

ДОСЛІДЖЕННЯ ДИНАМІЧНИХ ХАРАКТЕРИСТИК ПРОЦЕСУ ШЛІФУВАННЯ ЦИЛІНДРИЧНИХ ПОВЕРХОНЬ ПЕРИФЕРІЄЮ ОРІЄНТОВАНОГО КРУГА В РЕЖИМІ ЗАТУПЛЕННЯ НА ВЕРСТАТІ ВЗ208 Ф4

Urgency of the research.. A large number of parts in mechanical engineering that have surfaces of rotation, get the final accuracy of size, shape, and roughness in circular grinding operations. The study of grinding parameters with crossed axes of the wheel and the part in the blunting mode is an urgent task, as it will increase processing productivity, product accuracy and tool stability and ensure higher competitiveness of products in various fields of mechanical engineering. Target setting. In the final grinding operations, it is desirable to create conditions and mode that ensure the operation of the wheel in the mode of predominant blunting or partial self-sharpening, when there is a slight dimensional wear. This mode is characterized on the one hand by increased blunting of abrasive grains and salinization of the surface of the wheel and on the other helps to preserve the shape of the wheel after editing, so it is necessary to conduct dynamic studies whose results are taken into account when constructing the grinding process. Actual scientific researches and issues analysis. Analysis of recent research and publications. Scientific school under the leadership of Dr., Prof. Kalchenko VI the method of circular grinding in the mode of self-sharpening with crossed axes of a detail and preparation is investigated and the ways of increase of stability of abrasive wheels and accuracy of processing are offered. Uninvestigated parts of general matters defining. Selection of previously unexplored parts of the general problem. Investigation of the dynamic characteristics of the grinding process in the blunting mode on the machine VZ208 F4. The purpose of the article. To provide high indicators of the accuracy of the sizes, low roughness and undulation of the processed surfaces when grinding in the blunting mode. Carry out a dynamic calculation of the spindle assembly and establish the areas of its resonant operation, construct the amplitude phase-frequency response (AFCH) and determine the dynamic stability of the system. The presentation of the main material. There are grinding in the mode of self-sharpening and the predominant blunting of the tool. In the self-sharpening mode, the wear of the grinding wheel leads to a change in its original (correct) geometric shape, which, in turn, intensifies the vibrations of the process system, reduces dimensional accuracy and the formation of corrugated parts on the machined surfaces. In the final grinding operations, it is desirable to create conditions and mode that ensure the operation of the wheel in the mode of predominant blunting or partial self-sharpening, when it provides a slight dimensional wear. Conclusions and suggestions. The dynamic characteristics of the process of grinding cylindrical surfaces by the periphery of the oriented circle in the mode of blunting on the machine VZ208 F4 are investigated in the work. The conducted researches allow to minimize cutting forces, to establish areas of resonant work of the machine, to increase intervals between edits and stability of a grinding wheel, to provide higher accuracy and quality of the processed surfaces, and also to increase productivity of processing.
