A comparative analysis of the stress-strain state of disc specimens in assessing the structural strength of materials

A study of the stress-strain state (SSS) of disc specimens has been conducted when testing specimens with stress concentrators (grooves). The research has shown that the truncation of circular discs along two symmetrical chords makes it possible to change the type (the ratio of principal stresses) of SSS that occurs at the destruction site. Therefore, these specimens can be used to assess the structural strength of materials on standard single-drive testing machines, taking into account the real type of SSS that occurs in the bearing elements of machines. The results of numerical SSS modeling have been used to build the dependences of the SSS type and level on geometric parameters of specimens. Geometrical parameters can be chosen for a certain SSS type to assess both the static and fatigue strengths of materials used in the manufacture of bearing elements.

Temperature and Electric Field Distribution Characteristics of a DC-GIL Basin-Type Spacer with 3D Modelling and Simulation

The temperature properties of real-type direct-current gas-insulated transmission lines (DC-GIL) with a basin-type spacer were investigated by the finite element method in this paper. A horizontally installed model was established and the temperature distribution was obtained with a 3D model. The specific heat capacity and thermal conductivity of the spacer were measured and applied in the simulation. The results show that the temperature of the convex surface was slightly higher than that of the concave surface. With an increase in the SF6 pressure, the temperature of the spacer decreased, which can be attributed to the improvement of convection due to increases in the heat capacity per unit volume. With an increase in the ambient temperature, the temperature of the spacer increased linearly. The temperature difference between the inner and outer parts of the spacer increased with increases in the load current. Besides, an obvious increase in the surface electric field strength appeared under the influence of the thermal gradient compared to the results without the thermal gradient. Thus, special attention should be paid to the insulation properties of the spacer considering the influence of temperature distribution. This study evaluates both the thermal and insulation characteristics of the GIL along with the spacer under various conditions.

Angel Faces, Killer Kids, and Appetites for Excess: Reapproaching Moral Panic

<p>It is argued that the contemporary era is one proliferated with moral panics (Thompson, 1998). This is just as the concept of moral panic, which has enjoyed nearly forty years of analytical purchase, is being ‘rethought’ with an impetus to connect its processes with developments in social theory. Underpinning this rethink is a primary question: what are moral panics extreme examples of? It is evident in the literature, however, that there is a varying degree to which a more longstanding question – why moral panics occur – is addressed as part of this rethink. I propose in this thesis that these questions are intimate with each other; that only by understanding why real episodes occur can a supposition of what the concept of moral panic is in an abstract sense begin. Another – related – proposal is that while the conjectural question remains elusive the approach to empirical cases of moral panic be in real-type/ideal-type terms. That is, that at the same time as the concept is employed to understand phenomena occurring in tangible social situations, a reflection upon the concept (the ideal-type) is undertaken in relation to how the real-type case under investigation challenges and/or supports its interpretative parameters. To demonstrate these relationships and their study, I examine in this thesis the case of ‘killer kids’, which emerged in 2002 and spanned across the sociopolitical landscape of Aotearoa/New Zealand for the next six years. At the heart of this case was a set of news images of a child, who at twelve years of age had been involved in a heinous crime resulting in the death of pizza delivery person Michael Choy. Seeking to understand how and why these images were fundamental to how this ‘real-type’ episode of moral panic unfolded in this space and time, I employ a two-component approach inspired by Norman Fairclough’s (1995a) Critical Discourse Analysis. The first component deconstructs the realtype case via a three-tiered analytical framework: content, process, and context. The second component reflects upon these tiers (in parts and as a whole) in relation to Stanley Cohen’s (1972) application of a ‘cycle of deviance amplification’ in addition to the stages of panic as described in his seminal work Folk Devils and Moral Panics. From the processual and contextual factors identified at play in the construction of ‘killer kids’ I conclude with a suggestion that moral panic can be thought of as a set of appetites that come together in an explosive discharge of excess energy.</p>

Method for fast classification of MNIST digits on Arduino UNO board using LogNNet and linear congruential generator

The paper presents a method for forming a reservoir of a neural network LogNNet using a linear congruent pseudo-random number generator. This method made it possible to reduce the MNIST handwritten digit recognition time on the low-memory Arduino Uno board to 0.28 s for the LogNNet 784:20:10 configurations, with a classification accuracy of ~ 82%. It was found that the computations with integers gives an increase in the speed of the algorithm by more than 2 times in comparison with the algorithm using the real type when generating a chaotic time series. The developed method can be used to accelerate the calculations of edge devices in the field of “Internet of Things”, for example, for mobile medical devices, autonomous vehicle control systems and bionic suit control.

An Introduction to Vladimir Solovyev’s Three Conversations on War, Morals and Religion

This paper aims at reflecting on Vl. Solovyev's Three Conversations as a philosophical and religious fable. The stress is put on studying each of the protagonists: the Lady, the General, the Politician, Mr. Z, the Prince, as well as the Antichrist and the heads of the three main Christian denominations: the pope, the starets John and prof. Pauli. Each of them is presented both as a real type with his own idiosyncrasies (which is very important) and as an illustration of the truths and deficiencies of his time and milieu, keeping in mind the idea (so dear to Solovyev) that the people who actually promote and contribute to the good can only be those who have maintained a sense of humour and are the bearers of an honest, simple and authentic cultural and spiritual tradition, even if it is incomplete. The Antichrist seduces people by encouraging muddle-headedness, libido dominandi, intellectual pride and the taste for the sublime. Through those means he conquers, before being ultimately defeated by his own nothingness.

Spinors of real type as polyforms and the generalized Killing equation

We develop a new framework for the study of generalized Killing spinors, where every generalized Killing spinor equation, possibly with constraints, can be formulated equivalently as a system of partial differential equations for a polyform satisfying algebraic relations in the Kähler–Atiyah bundle constructed by quantizing the exterior algebra bundle of the underlying manifold. At the core of this framework lies the characterization, which we develop in detail, of the image of the spinor squaring map of an irreducible Clifford module $$\Sigma $$ Σ of real type as a real algebraic variety in the Kähler–Atiyah algebra, which gives necessary and sufficient conditions for a polyform to be the square of a real spinor. We apply these results to Lorentzian four-manifolds, obtaining a new description of a real spinor on such a manifold through a certain distribution of parabolic 2-planes in its cotangent bundle. We use this result to give global characterizations of real Killing spinors on Lorentzian four-manifolds and of four-dimensional supersymmetric configurations of heterotic supergravity. In particular, we find new families of Einstein and non-Einstein four-dimensional Lorentzian metrics admitting real Killing spinors, some of which are deformations of the metric of $$\text {AdS}_4$$ AdS 4 space-time.

Lumbar plain radiograph is not reliable to identify lumbosacral transitional vertebra types according to Castellvi Classification principle

Background: The anteroposterior view of lumbar plain radiograph (AP-LPR) was chosen as the original and first radiographic tool to determine and classify lumbosacral transitional vertebra with morphological abnormality (MA-LSTV) according to Castellvi Classification. However, recent studies found that AP-LPR might not sufficient to detect or classify MA-LSTV correctly. The present study aims to verify the reliability of AP-LPR on detecting and classifying MA-LSTV types, taking coronal reconstructed CT images (CT-CRIs) as gold criteria. Methods : Patients with suspected MA-LSTVs determined by AP-LPR were initially enrolled. Among them, those who received CT-CRIs were formally enrolled to verify the sensitivity of AP-LPR on detecting and classifying MA-LSTV types according to Castellvi classification principle. Results : 298 cases were initially enrolled as suspected MA-LSTV ones, among whom 91 cases who received CT-CRIs were enrolled into the final study group. All suspected MA-LSTVs were verified to be real MA-LSTV ones by CT-CRIs. However, 35.2% of the suspected MA-LSTVs types judged by AP –LPR were not consistent with final types judged by CT-CRIs. Two suspected type IIIa and 20 suspected IIIb ones were verified to be true, while 9 of 39 suspected IIa, 9 and 3 of 17 suspected IIb , and 11 of 13 suspected IV ones were verified to be real type IIIa, IIIb, IV and IIIb ones by CT-CRIs, respectively. Incomplete joint-like structure (JLS) or bony union structure (BUS), and remnants of sclerotic band (RSB) between the transverse process (TP) and sacrum were considered to be the main reasons for misclassification. Conclusion : Although AP-LPR could detect MA-LSTV correctly, it could not give accurate type classification. CT-CRIs could provide detailed information between the TP and sacrum area, and could be taken as gold standard to detect and classify MA-LSTV.

An Efficient Encrypted Floating-Point Representation Using HEAAN and TFHE

As a method of privacy-preserving data analysis (PPDA), a fully homomorphic encryption (FHE) has been in the spotlight recently. Unfortunately, because many data analysis methods assume that the type of data is of real type, the FHE-based PPDA methods could not support the enough level of accuracy due to the nature of FHE that fixed-point real-number representation is supported easily. In this paper, we propose a new method to represent encrypted floating-point real numbers on top of FHE. The proposed method is designed to have analogous range and accuracy to 32-bit floating-point number in IEEE 754 representation. We propose a method to perform arithmetic operations and size comparison operations. The proposed method is designed using two different FHEs, HEAAN and TFHE. As a result, HEAAN is proven to be very efficient for arithmetic operations and TFHE is efficient in size comparison. This study is expected to contribute to practical use of FHE-based PPDA.
