Surface waves in multilayered elastic media I. Rayleigh and Love waves from buried sources in a multilayered elastic half-space
Authors: Harkrider David G. 
Published: July 2021

ABSTRACT
A matrix formulation is used to derive integral expressions for the time transformed displacement fields produced by simple sources at any depth in a multilayered elastic isotropic solid half-space. The integrals are evaluated for their residue contribution to obtain surface wave displacements in the frequency domain. The solutions are then generalized to include the effect of a surface liquid layer. The theory includes the effect of layering and source depth for the following: (1) Rayleigh waves from an explosive source, (2) Rayleigh waves from a vertical point force, (3) Rayleigh and Love waves from a vertical strike slip fault model. The latter source also includes the effect of fault dimensions and rupture velocity. From these results we are able to show certain reciprocity relations for surface waves which had been previously proved for the total displacement field. The theory presented here lays the ground work for later papers in which theoretical seismograms are compared with observations in both the time and frequency domain.
A catalog of Southern California earthquakes, and associated electronic data processing programs
Authors: Nordquist John M. 
Published: July 2021

Abstract
Epicenters, origin times, and other pertinent data on approximately 9000 earthquakes in the Southern California region, determined by the Seismological Laboratory at Pasadena for the period from January 1, 1934 to May 17, 1963, have been entered on IBM punched cards. This card catalog may be used as input for programs run on the IBM 7090, and has been converted to punched tape for input to the Bendix G-15D in use at the Laboratory. Programs now operational on the G-15D will produce from the catalog lists of earthquakes which satisfy given criteria of geographical location and/or magnitude range.
A system of G-15D programs for calculating from the catalog the distribution of seismicity over the region is described.
Model study of seismic waves from explosions in rectangular cavities
Authors: Gupta I. N. , Kisslinger C. 
Published: July 2021

Abstract
The patterns of radiation of P and S waves generated by firing a charge in a rectangular hole, about 2 × 5 mm, in a thin sheet have been determined. Plexiglas and aluminum have been used as the model materials.
It is shown that Knopoff and Gilbert's theory for bilateral cracking along a plane in an infinite medium and Heelan's theory for radiation from a cylinder give the same radiation patterns if the plane of observation is normal to the plane of the crack in the first case and includes the axis of the cylinder in the second, when the axis of cylinder is oriented in the direction of the crack. The observed radiation patterns agree satisfactorily with the predictions of these theories.
Primary ground displacements and seismic energy near the gnome explosion
Authors: Berg Joseph W. , Trembly Lynn D. , Laun Philip R. 
Published: July 2021

Abstract
Near-source measurements of seismic waves from gnome have been compared with a theoretical seismic source model derived by Blake (1952). It is estimated that 75 percent of the seismic energy in the primary waves is contained in the first half cycle of the ground displacement as shown on the seismograms from instruments located between 0.3 and 10 km from the explosion. The geometrical attenuation of the radiation field of the displacement wave is probably closely approximated by spherical divergence at ranges near the explosion. There is some evidence that a long-period displacement field may exist near the explosion as predicted by the theoretical model. However, there are not sufficient empirical data from the gnome explosion to make a detailed comparison between theory and observation.
Developing the paradigm of environmental management in agriculture (to the 175-th anniversary of V.V. Dokuchaev)
Authors: Kiryushin V. I. 
Published: July 2021

The main stages of the formation of ecological paradigms of environmental management are considered, the fundamental role of V.V. Dokuchaev ideas and the importance of following V.I. Vernadskiy works in their development are shown. The role of scientists of the Club of Rome in the development of the ideology of sustainable development and its controversial perception by the world scientific community is reflected. The analysis of the existing paradigms, in particular of the co-evolutionary paradigm, and its implementation in the theory and practice of adaptive-landscape farming systems is given. The priority tasks for its improvement are defined. Further prospects for its development are considered in the framework of the proposed constructive-biospheric paradigm of environmental management, which implies the creation of a network of agricultural landscapes (agricultural, water, land reclamation, agro-industrial, rural forestry, livestock, residential) in compliance with the ecological status of the territory. The grouping of ecological functions of the landscape and mechanisms of their transformation into socio-economic functions are considered as tools for landscape-ecological planning and design.

Published: July 2021

The strength of Islamic boarding schools spread across the archipelago is their enormous potential as an instrument of anti-radicalism, which generally fosters and teaches a culture of peace and shows more tolerance. So this article aims to describe the construction of the value of tolerance in order to counteract radicalism in Islamic boarding schools. The method used in this paper is a qualitative method, using a sociocultural, phenomenological and educational approach. In this article, it can be revealed that the value of tolerance that can be instilled in students in Islamic boarding schools to prevent the emergence of radical ideologies is first, to apply tolerance in terms of aqidah or belief, namely acknowledging the existence of other religions and giving freedom to each individual to embrace it. Second, tolerance in religious rituals, namely understanding that each religion has different teachings in worship procedures. Third, tolerance in social relations, namely the association and social interaction of people of other religions is not prohibited as long as it does not conflict with the control. Because tolerance between religious communities in worldly converts is indeed recommended to help each other, live in harmony regardless of differences in religion, ethnicity, language and race. This is a mainstream pesantren which actually displays a tolerant face, takes an accommodative attitude towards cultures without losing its monotheistic belief.

(Kekuatan pondok pesantren yang tersebar di Nusantara adalah potensi yang sangat besar sebagai instrumen anti radikalisme, yang pada umumnya membina dan mengajarkan budaya damai serta lebih banyak menampakan toleransi. Maka artikel ini bertujuan untuk mendeskripsikan konstruksi dalam penanaman nilai toleransi guna menangkal faham radikal di pondok pesantren. Adapun metode yang diguanakan dalam penulisan ini adalah metode kualitatif, dengan menggunakan pendekatan sosiokultural, fenomenologi dan edukatif. Dalam artikel ini, dapat diungkapkan bahwa nilai toleransi yang dapat ditananamkan kepada santri di pondok pesantren guna menangkal munculnya faham radikal adalah pertama, berlaku toleransi dalam hal aqidah atau keyakinan, yakni mengakui esksistensi agama lain dan memberi kebebasan kepada setiap individu untuk memeluknya. Kedua, toleransi dalam ritual keagamaan, yakni memahami bahwa masing-masing agama mempunyai ajaran berbeda-beda dalam tata cara peribadatan. Ketiga, toleransi dalam hubungan social, yakni pergaulan dan interaksinya dalam sosial umat agama lain tidak dilarang sepanjang tidak bertentangan dengan control tersebut. Karena toleransi antar umat beragama dalam mualamah duniawi memang dianjurkan supaya tolong menolong, hidup dalam kerukunan tanpa memandang perbedaan agama, suku, bahasa dan ras. Hal ini merupakan mainstream pesantren sesungguhnya menampilkan wajahnya yang toleran, melakukan sikap akomodatif atas kebudayaan-kebudayaan tanpa kehilangan keyakinan tauhidnya.)

Published: July 2021

Currently, the means of measuring and converting information signals from equipment are widely used in industrial processing systems.
For the most part, modern systems of mechanical processing of materials use mainly single-channel systems that work on information signals that identify the physical parameters of the technological process. Such a narrow specialization of monitoring one of the parameters usually reduces the reliability of the results obtained and, as a consequence, the reliability of the entire control system.
The task of the work is to determine the possibilities of creating the foundations of the automated system on the basis of multi-channel information recording devices from processing equipment and possible approaches to the choice of criteria for the analysis of fluid information.
As a result of the given analysis of a condition of branch and its modern transformations, the module of system for data collection on process (from a set of sensors) is offered for development, with a possibility of their further transformation on certain dependence, storage, transfer, and a possibility of signaling of certain events, for example, faults, for use in production automation systems and for equipment not included in the systems.
At the same time, the multi-channel device of the sensor system provides opportunities to determine the full amount of information about the process. The basic modern means of control of work of technological processing CNC-equipment applied in the industry are investigated.
The most perspective directions of development of multicriteria methods and automated control systems of technological equipment in the part of creation of complex sensors are determined. These sensory complexes register signals that are different in physical phenomena. The main approaches to the creation of control systems provide opportunities to build a theoretical basis given the logic of the system of obtaining specific information data in the automation of technological processes.
Promising research at creating algorithms for such complex systems of quality control and diagnostics of technological processes can be aimed.
MOVEMENT ALGORITHM OF AN AUTONOMOUS ROBOT-HEXAPOD FOR MOVING IN NARROW CLOSED SPACES
Authors: Platov Ilya , Pavlovskyi Oleksii 
Published: July 2021

The article proposes the use of a walking robot - hexapod for its use to monitor the technical condition of ventilation shafts, technical dry channels, enclosed spaces, etc. The peculiarity of this type of robots is the increased possibility in comparison with tracked or wheeled machines, due to their design and ability to overcome irregularities. Also, in comparison with existing designs, the hexapod can be fully autonomous and does not depend on a stationary power source. In its turn, construction of walking robots requires development of complex algorithms of motion, which are significantly different compared to wheeled or tracked moving devices, because in addition to the control of limbs, which are set in motion by servo drives, the computer core must process information from sensors that provide information both about the position of the robot itself, and about the surrounding objects, which can be: distance sensors, touch sensors, video cameras, accelerometers, gyroscopes, etc.
The paper highlights the developments used to date, but analysis of existing algorithms for walking robots showed a lack of such for the use of the robot in narrow and confined spaces, ventilation shafts, dry technical ducts, etc. In this regard, an algorithm was developed that partially closes this gap. The peculiarity of this algorithm is the simplicity of practical implementation, as well as the safety of the construction of work in progress, because it takes into account the need for increased static stability by modifying the matrix of limb position by a third state, which gives the opportunity to consider the initial position, or memorize the limb state, from which, in the future, you can continue the movement from an arbitrary stable position. In addition, the algorithm can be applied not only to robots with six limbs, but also to other kinds of mobile walking platforms, because the proposed variant allows testing and calibration of any type of gait at each iteration of the step.
In the future, it is planned to test the proposed algorithm on the developed prototype not only when moving the work on horizontal surfaces, but also on vertical surfaces, which is an important component for the proposed application area.
