Reaction mechanisms of alkali-activated materials
Authors: Marvila Markssuel Teixeira , Azevedo Afonso Rangel Garcez de , Vieira Carlos Maurício Fontes
Published: April 2021

abstract: The Alkali-Activated Materials (AAM) are defined as materials obtained through the reaction between precursors and activators, and are separated into two classes depending on the products formed in the reaction, those rich in calcium, as the blast furnace slag, whose Ca/(Si+Al) ratio is higher than 1; and poor in calcium, which is the geopolymers subclass. In this review article, some bibliographical aspects were discussed regarding the discovery of these materials, through research conducted by Victor Glukhovsky and through the characterization of historical monuments by Davidovits, which began in the 50s and 60s and persist to the present day. The main products obtained in the alkaline activation reaction were also addressed, using the definition of polysialates and zeolites, in the case of geopolymers, and the tobermorite structure, in the case of materials rich in calcium. The main steps of the alkali-activated reaction, such as dissolution, condensation, polycondensation, crystallization, and hardening, were discussed. Some techniques for characterizing the AA reaction products were also examined, such as X-ray diffraction (XRD), nuclear magnetic resonance spectrometry (NMR), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). Finally, the main factors that interfere in the kinetics of AA reactions were explored, in which the type of cure and the activating solution used in the alkali-activated materials production stands out.
The AI Liability Puzzle and A Fund-Based Work-Around
Authors: Erdelyi Olivia J. , Erdelyi Gabor
Published: April 2021

Confidence in the regulatory environment is crucial to enable responsible AI innovation and foster the social acceptance of these powerful new technologies. One notable source of uncertainty is, however, that the existing legal liability system is unable to assign responsibility where a potentially harmful conduct and/or the harm itself are unforeseeable, yet some instantiations of AI and/or the harms they may trigger are not foreseeable in the legal sense. The unpredictability of how courts would handle such cases makes the risks involved in the investment and use of AI difficult to calculate with confidence, creating an environment that is not conducive to innovation and may deprive society of some benefits AI could provide. To tackle this problem, we propose to draw insights from financial regulatory best practices and establish a system of AI guarantee schemes. We envisage the system to form part of the broader market-structuring regulatory frameworks, with the primary function to provide a readily available, clear, and transparent funding mechanism to compensate claims that are either extremely hard or impossible to realize via conventional litigation. We propose it to be at least partially industry-funded. Funding arrangements should depend on whether it would pursue other potential policy goals aimed more broadly at controlling the trajectory of AI innovation to increase economic and social welfare worldwide. Because of the global relevance of the issue, rather than focusing on any particular legal system, we trace relevant developments across multiple jurisdictions and engage in a high-level, comparative conceptual debate around the suitability of the foreseeability concept to limit legal liability. The paper also refrains from confronting the intricacies of the case law of specific jurisdictions for now and—recognizing the importance of this task—leaves this to further research in support of the legal system’s incremental adaptation to the novel challenges of present and future AI technologies.

Loch Drunkie: Underwater lining of a 150-year-old cast iron outlet pipe
Authors: Lockett Stephen , Morrin Ross
Published: April 2021

Loch Drunkie is retained by two earth dams built in 1859. The outlet pipe is a 24 in dia. cast iron pipe through the highest part of the east dam with downstream control only. Although no record drawings exist, it is considered that the pipe is laid directly within the foundation or embankment fill and the presence of any concrete surround is unlikely. The pipe is over 160 years old and, due to the valve arrangement, is always subject to internal pressure from the reservoir. The east dam was inaccessible with no vehicular access to within 500 m. In the 2014 Statutory Report, a recommendation in the interest of safety was made to ascertain the condition of the outlet pipe and carry out any works deemed to be required to reduce any potential threats posed to the safety of the dam. This paper describes the series of investigations and subsequent pipe lining works that were carried out at the reservoir. Due to concerns regarding the integrity of the pipe, all investigations and pipe lining works had to be carried out with the reservoir at top water level to ensure the internal pressure to the pipe was maintained throughout.

The article presents the results of experimental studies of the possibility of assessing the resource of various structures made of polymer composite materials (PCM) when applying power loads (uniaxial power static and cyclic) to them based on the analysis of the results of their non-destructive testing and industrial building objects using artificial neural networks (ANNs). It is shown that the error in assessing the service life of structures from PCMs when they are loaded with a uniaxial power load and cyclic load using the proposed method does not exceed 15 %, and for industrial construction objects, the dependence of the probability of a pre-emergency state on the operating time is formed. The data obtained allow timely repair work of structures or their decommissioning and prevent emergencies.

The paper studies a previously proposed method for calculating the current accuracy characteristics of a correlation-extreme search algorithm for solving the map-aided navigation problem. The proposed method is based on the analysis of the ratio of the extreme values of the functional used in the search algorithm for comparing the measured field fragment, and the fragments obtained from a reference map, and on determining the diameter of the set of the given level for this functional. The study is carried out using an example of three spatial geophysical fields: the sea depth field, the field of gravity anomalies, and the anomalous magnetic field; it is focused on their application for underwater vehicle navigation. The specific features of the information and measurement systems used in the survey of these fields, done by means of an underwater robot are described, as well as the procedure simulating the mapping process taking these features into account. The results of computer experiments on comparison of the proposed method for calculating the current accuracy and the method used in the Bayesian algorithm for solving the navigation problem are presented.

The most critical element of Hemispherical Resonator Gyroscope (HRG) is the high quality factor (Q-factor) mechanical resonator. This paper discusses the role of thermoelastic damping (TED) on effective Q-factor. Finite element method (FEM) is used to solve this highly coupled field problem involving vibration, solid mechanics, heat transfer and thermodynamics. The major contribution of this paper is the sensitivity analysis of the effect of material property, operating temperature and dimensions to arrive at macro scale resonator configuration. Hybrid hemispherical-cylindrical configuration is proposed by studying the performance parameters such as effective mass and angular gain.The uniqueness of the present work is the sensitivity study of ultra thin film coating (volume fraction of 0.01%), coating variations and different coating configurations. The coating can reduce the Q-factor by a few orders compared to uncoated shell. It has been found that coating material selection and coating configuration are very important factors. Another significance of the present work is the realization and detailed characterization of the hybrid fused silica resonator. Thin film gold coating is done on the 3D surfaces of the realized precision resonator. Detailed coating characterization is carried out using sophisticated instruments. Very fine balancing to the order of a few mHz is achieved after coating. Q-factor measurement of the coated resonator is carried out using LDV and achieved a few millions in the final functional hybrid resonator.

Application of a Feedforward Neural Network to Predicting the Thermal Characteristics of Machine Tools
Authors:   Orenburg State University, Orenburg, Russian Federation, Polyakov A. N. , Pozevalkin V. V. ,   Orenburg State University, Orenburg, Russian Federation
Published: April 2021

he paper presents a procedure for studying the stability of modeling an artificial neural network as applied to the thermal characteristics of machine tools. The topicality of this procedure is dictated by the ambiguity of the results generated by the neural network when constructing the predicted thermal characteristics of machine tools. Therefore, to select one of the possible solutions generated by the neural network, it was proposed to use two criteria. The effectiveness of their use is confirmed by the presented machine experiments. The methodology proposed in this work has made it possible to form a generalized concept for studying the effectiveness of the use of neural network technologies in thermal modeling of machine tools. This concept defines a typical set of variable modeling parameters, a basic mathematical model based on a modal approach, and an architecture of a typical software tool that can be developed to study the effectiveness of artificial neural network modeling. For each variant of the input data of the network, the following parameters were varied: the number of neurons in the hidden layer; the size of the input and output vectors; input vectors error; the size of the training, validation and test sample; functional features of thermal characteristics supplied to the network input or their multimodality; the presence and absence of normalization of the input vector. The paper presents experimental thermal characteristics for two spindle speeds of a vertical CNC machine. The results of the machine experiment are presented for six variants of the variable parameters of the mathematical model. The software tool used to carry out the machine experiment was developed in Matlab.

Published: April 2021

Bipolar radio-frequency devices have all the theoretical prerequisites for use in combination with phototechnologies, while the properties of electro-optical synergy are manifested.

Material and method. The study included 125 patients aged 40 to 50 years. Depending on the therapy, patients were divided into 4 groups and subgroups A and B, depending on the identified predictors of the effectiveness of laser therapy.

The results of the study. After applying the combined methods, a more significant improvement in the quality characteristics of the skin was noted: an increase in skin moisture in the 1A group, the corneometry index increased by 24.6%, in the 1st group by 28.3%, in the 2A group by 38.9%, in the 2B group by 37.3%, in the 3A group by 29.1%, in the 3B group by 27.5%, in the 4A group by 38.8%, in the 4B group by 38.8%; an increase in skin elasticity in group 1A, the Ua/Uf indicator increased by 13.2%, in group 1B by 13.9%, in group 2A by 27.9%, in group 2B by 29.0%, in group 3A by 14.9%, in the 3B group by 14.6%, in the 4A group by 28.2%, in the 4B group by 28.2%, which was accompanied by a more pronounced decrease in the severity of wrinkles according to profilometry. The use of laser therapy (an erbium or neodymium laser) and microneedle RF therapy contributes to a more significant restoration of the epidermal-dermal structure of the skin, which is confirmed by ultrasound data: the microrelief has improved by more than 3 times compared with monotherapy, the thickness of the dermis is 2.2 times and acoustic density 1.7 times.

Published: April 2021

Widespread implantation of cardiac devices, i.e. cardiac pacemakers, cardioverter-defibrillators and cardiac resynchronisation devices improved patients survival. It has resulted in increase in number of ageing patients with cardiac devices who need physiotherapeutic treatment due to accompanied comorbidities. Hence the study of the interaction between functions of cardiac devices and physiotherapeutic treatment techniques is particularly relevant. The use and safety of physiotherapeutic treatment techniques producing electromagnetic field which in turn eventually cause harm of the cardiac devices are being discussed in present review article. The possible adverse effects of such interaction are abrupt failure to stimulate or triggering of shock therapy with consequent arrhythmic events including cardiac arrest. The technical characteristics particularly associated with electromagnetic interference are discussed here in detail. The attention is also payed to analysis of possible causes and effects of electromagnetic interference and safety measures as well.

Authors: Voropaev Alexey A. , Gerasimenko Marina Yu.
Published: April 2021

The relevance of the work is associated with the high prevalence and socio-economic significance of neurotic disorders associated with stress. Standards of medical care for patients with neurotic disorders associated with stress do not provide for the use of any physiotherapy or hardware effects. Drug therapy is mainly used, but its use is not always effective and is limited by the risk of developing allergies, drug addiction, toxic manifestations, side effects, etc. Therefore, more and more attention has been paid to non-drug treatment methods recently. Non-invasive neuromodulation is a therapeutic exogenous effect on various parts of the nervous system using an electromagnetic physical factor in the conditions of drug therapy.
Purpose. Study the effectiveness of noninvasive neuromodulation in patients with asthenic neurosis.
Material and methods. A total of 79 patients with the diagnosis of F48.0 Neurasthenia were studied (59 women and 20 men). The median age was 44 4.5 years. The main group 49 patients, 30 patients made up the control group. The course of non-invasive neuromodulation was performed against the background of medical treatment in accordance with the MES with the use of a pulse generator "TETOS" with feedback in the form of electroencephalography (registration certificate no.FRS2011/11198).
Results. Immediately after the end of the course of treatment, 80% of patients manage to achieve a significant improvement in their subjective state. As a result of the proposed method, not only significant, but also persistent improvement in the condition of patients is achieved.
Conclusions. The basis of this method is the interaction of two methods of treatment: physiotherapy and medication. As a result of the application of the proposed method, the main cause of the disease (psychotraumatic factor, life circumstances, etc.) is gradually identified, and the patient himself becomes aware of it, with subsequent correction of the condition. As a result, not only significant, but also persistent improvement in the condition of patients is achieved. According to the results of observations of the authors of the application, the disease does not resume for 1.52 years.
