Meshing Characteristics

The study deals with the meshing characteristics of cylindrical helical external gear pairs. The gear pairs, following the nowaday’s strength and quality requirements are becoming ever smaller. Accuracy in the background also attracts the importance of vibration and noise reduction. The inclined tooth meshing, in contrast to the straight tooth, due to the specificity of its zone of contact, is the subject of this study. This is of special importance because the meshing stiffness varies for one to more teeth pairs, the meshing contact lines are of continuously varying length during meshing, and as a consequence load sharing and distribution is changing with. This paper deals with the zone of contact and its geometric modification in order to light on a new type of vibrational excitation.

Data Gathering And Analysis

This article is based on data from a doctoral thesis about the “anthropology of life-threatening, death and time.” [1] The interpretation is made from twelve life reviews set at homes of people who suffered a serious, but not necessarily fatal illness. Two-cultural configurations are chosen along the axis of rural-urban polarity. It focuses on three types of solidarity, facing the awareness of death: 1) the ethnographic position, in data gathering and analysis. Specific propositions are given concerning the subject and intersubjectivity, cultural generalization of personal experiences, and scientific criteria; 2) what helps cope with illness. Pre-death practices are structured on the basic concept of resistance to illness and preparation for death practices rely on a coherence “test.” The genealogy of practices emerge in six situational and seven historical factors; 3) the conditions of a new type of rite before death and its functions, beside the institutionalization of illness and death.

A new type of case study, called the real-time case (RTC), was produced in the fall of 2001 and distributed via the Internet to business classes at four universities in the US and Canada. The real-time case presented the story of one company's growth and development throughout a 14-week semester. A case writer stationed full-time at the subject company published case installments weekly on the Web, allowing students to view the company-building process as it happened. The 14-week coverage of RTC enabled students to study the subject company in unprecedented depth and detail. RTC's real-time interactivity allowed students to share their analyses and best thinking with the company leadership during the company’s decision-making process.A major objective in producing the case was to heighten student engagement with the case material. To evaluate whether this objective was achieved, a survey and a focus group discussion were conducted with one of the participating MBA classes. Results from the survey and the focus group showed a high degree of engagement, plus many other benefits from the new type of case study.

Oma algses mitmetähenduslikkuses on see F. Baconi aforism kõige tihendatum tõdemus, mis tõmbab olemusliku eraldusjoone ühelt poolt antiikse ja keskaegse ning teisalt uusaegse arusaama vahele teadusest ja teadusteadmisest. Artiklis püüab autor anda võimaluste piires tervikpildi uusaja teaduse industriaalselt (tehnoloogiliselt) orienteeritud teadmistüübi tekkimisest. Uusaja teaduse kujunemiseks vajaliku pöörde maailmavaateliste eeldustena tuleb käsitleda: (1) põhimõtteliselt uut subjekti ja objekti käsitust; (2) täiesti uut väärtusruumi, uut teaduse ideoloogiat (ilmalikkus, kriitiline vaim, tõesus ja praktiline kasulikkus); (3) tunnetuslaadi muutust — kontemplatsioonilt interventsioonile, kvaliteedi kirjeldamiselt kvantiteedi uurimisele; (4) looduse käsitlemist Kosmose asemel seaduspäraselt korrastatud objektide “väljana”. Uue tunnetusstiili — empiirilise ja teoreetilise tunnetuse kokkuviimine, hüpoteetilis-deduktiivse metodoloogia kujundamine Galilei poolt, abstraktse ja sünteetilis-tekstilise loomuga spekulatsiooni asendumine uurimisobjekti ehituse, korrapära ja põhjuslikkuse objektiivse analüüsiga, universaalsete loodusseaduste doktriini kujunemine jms—kujunemine konstitueeris uut tüüpi teadmise. Teadmise kui nähtava maailma piltkoopia asemele luuakse teadmine kui loodusobjektide seaduspära analüütiline rekonstruktsioon. See on vormiltmatemaatiline, päritolult eksperimentaalne ning loodusobjektide kontrollimisele ja ümbertegemisele suunatud nn valdamisteadmine.This F. Bacon's aphorism in its original ambiguity is the most condensed belief that draws a distinctive essential line between ancient and medieval understanding of science and scientific knowledge on one hand and modern understanding on the other. The author aims at providing, as far as possible, an integral overview of emerging of the industrially (technologically) orientated type of knowledge of modern times. Ideological/philosophical preconditions of the change necessary for emerging of modern science are: (1) a fundamentally new approach to the subject and object; (2) a completely new system of values, a new ideology of science (secularity, critical spirit, trueness and utilitarianism); (3) a change in manner of cognizance - from contemplation to intervention, from describing quality to studying quantity; (4) treating nature as a naturally organised "field" of objects instead of the Cosmos. Emerging of a new style of cognizance - bringing together of empirical and theoretical cognition, the devise of the hypothetical-deductive method by Galilei, replacement of speculations abstract and synthetic-textual in nature with objective study of the structure, regularity and causality of the object of study, establishment of the doctrine of universal natural laws etc - constituted a new type of knowledge. Knowledge as a copy of the visible world is replaced by knowledge as an analytical reconstruction of the regularity of natural objects. It is so-called dispositive knowledge, morphologically mathematical, originally experimental and aimed at control and alteration of natural objects.

The article considers the philosophical aspect of defining the immanence and attribution of the concept of “tolerance” to the culture itself. The subject of the research is especially relevant due to the modern processes that are happening in the global world, and the difference in key methodological positions of modern Russian and Western science on this issue today. The purpose of this study is to clarify the philosophical basis of the existing opposition of societies with traditional ethical cultures (Russia, China) and the ‘new-type’ poly-state European ethnic community. Based on the analysis of current social processes in Russia and Europe using the comparative historical method, modelling methods and model extrapolation in the field of culture studies, social psychology and political science, the article identifies the main approaches to ethnic and social identity, their cultural and ideological components. The authors prove the hypothesis that culture requires designation of its border with another culture, recognition of this border, which distinguishes and confirms cultural semantics. Denial of this fact is a method of ideological manipulation of the ethno-social consciousness of society in the framework of globalisation processes

Subjective Identity

This article discusses selected aspects of the problem of self-perception by a sick individual, specific to the poetry of Polish women of the last few decades. The aim of the analysis is to show that the body is central to the illness experience and that a new type of intimacy appears in connection with its ailment. This is a „clinical intimacy”, the specificity of which is defined by a confrontation with suffering, the proliferation of the feeling of isolation, the intensity of emotions related to making the body public, its discovery and exposure in a hospital setting. The issue of „gender expropriation” in a marginal situation is also important, as is the scar, wound, physical violation of the body boundary, read as the „punctum” of the patient's body. The interpretation emphasises the individualization of artistic representations of the aforementioned aspects of „clinical intimacy”. The anthropological research perspective adopted in the sketch allows for the diagnosis of the subject matter in the context of the process of shaping subjective identity.

Tax evasion and grey economy are present in all countries. It’s es-timated that grey economy in developed EU countries is at around 10-15% of GDP, while it amounts to over 30% of GDP in Serbia. Therefore the subject of this paper is determining basic goals of Serbia’s tax policy, i.e. combating grey economy that complicates efficient resource allocation and slows down economic development, because economic subjects that are prone to tax evasion represent disloyal competi-tion to economic subjects that do business legally. In order to fight tax evasion, or-ganization and work of tax administration are of special importance.

The subject and purpose of this study is to examine the new type of coronavirus disease (COVID-19), which has turned into a global epidemic, with an economic-political approach. There are twin crises in the form of a health crisis (high human deaths) and an economic crisis (recession). Trillion-dollar aid packages from governments and international financial organizations also show that this global public health crisis has created an economic crisis. In the context of these crises, G-20 countries that did not intervene in their transmission channels in a timely manner showed the worst situations. This epidemic, calculated with the SIR model, is global, but the measures are local. What makes a clean, masked, and socially distant life obligatory against the risk of contamination is that this epidemic locks or restricts the whole economy, especially trade, education, and tourism. Measures called “new normalization” have started to relax in order to prevent further increase in unemployment and poverty.

A new type of FT pin-cycloid transmission reducer is widely used in the industrial robot field due to the high transmission accuracy. In addition, the complex working conditions bring about vibration, which affects the transmission accuracy of the robot. Therefore, it is necessary to study the dynamic characteristics of FT reducer at the transmission joint. In this paper, based on the analysis of its transmission principle and structure, the dynamic model of FT transmission is established by necessary assumptions. The stiffness mathematical models of different meshing positions are obtained from the dynamic model, and the differential equations of the system are established by Lagrange method. In order to solve the natural frequency of the system, the stiffness of meshing positions of the system is solved, including input shaft torsional stiffness, involute gear meshing stiffness, bearing stiffness, cycloid gear and pin torsional stiffness. Considering the output of FT transmission, a “3+ i” model is proposed to obtain the mesh stiffness between the cycloid gear and output pins. Finally, the correctness of the model is proved by choosing parameters such as transmission ratio and force on parts and components by simulation. The research results will provide theoretical support for the optimal design of FT transmission.

Wide Experience

An important and clearly marked recent trend in American government is that in the direction of systematic planning—local, state, and national. City planning has developed for the last twenty years, and there are now some 700 city planning agencies. The activities of these boards have been halted somewhat during the depression, although some 9,000 workers under the C.W.A. aided in the development of city plans in 1934. On the whole, the cities have fallen behind in the movement they started.The most significant single event in the urban field is the establishment of a new type of planning agency in Cincinnati, known as the department of economic security, an office through which the employment and reëmployment problems of that community are made the subject of governmental study and action, in cooperation with industry. The director is a man of wide experience and broad social vision in the person of Colonel Waite, one time city manager of Dayton and recently deputy administrator of public works

Background. The objective of this paper is to describe and conceptualize an unusual and probably rare condition: the intense longstanding desire to have an amputation.Method. Structured interviews were conducted by telephone of 52 subjects (mean age: 48·6, range 23–77 years; 47 male, 4 female, 1 intersexed) self-identified as having had a desire to have an amputation.Results. Seventeen per cent (n=9) had an arm or leg amputated with two-thirds using methods that put the subject at risk of death and one-third enlisting a surgeon to amputate their healthy limb. The most common reported reason for wanting an amputation was the subject's feeling that it would correct a mismatch between the person's anatomy and sense of his or her ‘true’ self (identity). None were delusional. For all but one subject age at onset was during childhood or early adolescence. For those who had psychotherapy or medication there was no change in the intensity of the desire for amputation. The six subjects who had an amputation at their desired site reported that following the amputation they felt better than they ever had and no longer had a desire for an amputation.Conclusions. These preliminary results suggest the existence of an extremely unusual clinically distinct condition characterized by a lifelong desire to have an amputation of a particular limb. The condition is associated with serious negative consequences: amputation attempts, impairment and marked distress. Reflecting similarities between Gender Identity Disorder and this condition, the author suggests that it may be conceptualized as an unusual dysfunction in the development one's fundamental sense of anatomical (body) identity.
