Authors: Kushitashvili Zurab , Bibilashvili Amiran 
Published: December 2020

Abstract
Modern technologies for creating integrated circuit elements offer many innovations, both in terms of the technological cycle and the introduction of new technologies. Stimulated processes in this regard and their mechanism require a thorough study in order to further improve the technology and the parameters of the micro and nano devices made on their basis. We have studied the processes stimulated by ultraviolet radiation, such as Stimulated Plasma Anodizing and Stimulated Magnetron Sputtering. In the study of stimulated mechanism should be considered processes which are going on with ultraviolet irradiation on the sample and plasma. In these processes, the UV light effects on the plasma, on the surface of the synthesized material, its volume, and the interface area of the material. In particular, in the case of plasma anodizing, UV radiation: 1) produces ozone in the plasma that is much more active than oxygen ion. 2) Ionizes interface area of Plasma-oxide, producing additional current carriers, and 3) transferring electrons from the oxidized material bond zone to the anti-bond zone, thereby weakening the bond strength between the oxide atoms. Because of these effects, the process of mixing anions and cations is facilitated and, consequently, the oxygen diffusion coefficient is increased and the oxidation process is accelerated. At the oxide-semiconductor interface happens roasting existing charge trapping levels, which reduces the concentration of charge carriers and improves the oxide parameters. The same processes are observed in the case of Magnetron Sputtering. In the deposited layer excites mechanical tensions and it can be removed by UV irradiation in the same way as in the case of plasma anodizing.

Published: December 2020

Abstract
Amorphous substances, including glasses, are very important kind of value materials for numerous applications. Among the glasses the impact matter has especially high fundamental interest and use potential, being formed under extremely high PT conditions - up to hundreds GPa and thousands degrees Celsius. In this direction the detail studies of new natural occurrences with UHPHT impact glasses and their features are very actual fundamentally and probably potentially useful for new ideas for technologies. Our analytical studies of the UHPHT ribbonlike impact glasses of the Ust`-Kara area at the Baydarata Bay (Kara Sea, Arctic Ocean) revealed the presence a number of special features such as multilevel differentiation of impact melt and coesite abundance. The specifics of the Ust`-Kara UHPHT glasses rather point to bottom facies of the suevitic breccia. The observed impactites characteristics allow to see new geological importance of the studied Ust`-Kara suevites, allow to correct geological model of the impact structure.

Published: December 2020

Abstract
The unusual natural ultrahigh pressure high temperature (UHPHT) impact glasses have been discovered at the Southern part of the Kara astrobleme (Pay-Khoy, Russia) in 2015. The glasses form a complex of stockwork-like system of thin vein bodies set within suevite breccia at the right bank of the Kara river. The Kara glasses have many specific features pointing to UHPHT origin. For better understanding of the geological position of the UHPHT impact glasses we have provided additional field observation with the use of copter facility to observe the outcrops from the «air-bird high» and collecting data for 3D modeling. Here we present natural topological details for the more complete analysis of the discovered UHPHT complex at the Kara River (Pay-Khoy, Russia) and “bottom flow” suevites with UHPHT impact ribbon-like glasses on the Baydarata Bay shore (Kara Sea, Arctic, Russia).

Authors: Balan Stefan Florin , Tiganescu Alexandru , Apostol Bogdan Felix 
Published: December 2020

Abstract
The paper intends to evaluate and analyze the accelerometric data recorded on certain buildings located in the Bucharest metropolitan area, one of the most exposed in Europe, with three strong earthquakes with magnitude MW>7 in the last century. Starting from information comprised by databases for soils and buildings existing in Bucharest, certain types of structures were selected, according to their specificity (old buildings, retrofitted, etc.) and being continuously seismic monitored. The selected three buildings are equipped with seismic isolators and viscous dampers. The response of these structures, at the ground level, subjected to medium intensity earthquakes will be discussed in terms of peak accelerations and spectral accelerations. Based on the currently accepted standpoint that the dynamic response of certain structures subjected to earthquakes is strongly dependent of the ratio between the natural period of the structure and the dominant period at the construction site, a comparative analysis against free-field data is presented. There would be presented the improvement of seismic response of isolated buildings in Bucharest and the reason these buildings were protected choosing this method. The aim is to provide warnings regarding the severity of seismic events, by means of characteristics of the ground motion, gathered from the response spectra, which may be given soon after the seismic event took place. All the data recorded on instrumented structures during two seismic events (MW = 5.5 and MW = 4.8), together with the subsequent analysis, can represent a reference study for future earthquakes with similar magnitude. The integration of near-realtime seismology with performance-based earthquake engineering allows for providing the information useful for earthquake engineers and decision makers and can enhance the mitigation of seismic risk.
Spatial Planning System: A Comparative Analysis East-Timor/Portugal
Authors: Santos Ana , Virtudes Ana 
Published: December 2020

Abstract
Each country has its own spatial planning system comprising a set of instruments and goals focused on the cities issues and territorial development. After a period of administration by the United Nations, on 20 May 2002 East-Timor, officially the Democratic Republic of Timor-Leste, became one of the youngest nations in the 21st century, having become a democratic rule of law. To promote the development of its territorial cohesion, on April 19, 2017, the Basic Law on Spatial Planning was approved in this island country in Southeast Asia. It intends to translate a set of principles contained in the National Constitution that could manage the praxis of spatial planning, focused on cities and territorial improvements. Consequently, there is a framework establishing the basis of public policies for this country whose primary objective is to accomplish the territorial quality, regarding the collective culture that integrates the values of the local culture. Given that East-Timor was part of Portugal until 1975, there is still a strong identity between both countries, sharing not only the same language but also several other aspects of culture, politics, and administrative organization. In this sense, this article aims to present a comparative analysis between spatial planning systems in East-Timor and Portugal, in order to find common features and particular aspects. Among the conclusions, this research shows that the land-use bases in East-Timor are similar to the Portuguese system, although it has fewer levels of intervention regarding the public administration framework. In East Timor, there are only spatial planning figures for national and municipal level, with no regional nor inter-municipal levels such as in Portugal.
East Timor: Steps Towards a Sustainable Urban Development
Authors: Santos Ana , Virtudes Ana 
Published: December 2020

Abstract
The recognized importance of the role of cities for the overall quality of life of citizens involves the preservation of the identity of the places without restricting the capacity to respond to the future requirements of societies and their territories. The current century has been pressing for the urgency of providing adequate urban policies to cities, particularly in developing countries, as is the case with East-Timor. Despite its recent independence, East-Timor doesn’t lose its time and the country has been focused in the definition of territorial policies and development strategies, in order to promote territorial cohesion and to specifically define the purposes and the fundamental principles that guarantee equal opportunities for all citizens in access to infrastructures, equipment and urban functions. Therefore, on April 19, 2017, the Basic Law on Spatial Planning was approved by the National Assembly. Efficient public territorial management and organization is only possible with detailed knowledge of the use of its entire territory. Administrative political decisions related to the territory happen more efficiently with the existence of this knowledge. Consequently, the present National Law for Spatial Planning issues provides for the existence of two major types of planning and territorial organization instruments: those of national scope and those of municipal or local scope. A set of several spatial planning instruments are proved to be imperative, for outlining strategic objectives for future interventions in this territory, achieving a territorial, social, economic, and sustainable development. The conclusions show that these objectives towards urban development will be supported by strategies that in turn will be materialized in actions that will enable the public sector individually or in partnership with privates. The main goal is to promote the transformation of the territory and that in a concerted and programmed manner contribute to a harmonious social and economic development supported by a fair and balanced load capacity of the natural environment.

Published: December 2020

Abstract
Based on an analysis of the processes in the supply circuit of ozone generators with periodic sinusoidal and pulsed voltages of high duty cycle, it is revealed that when powered by a sinusoidal voltage, a significant part of the energy consumed is spent on heat loss. Only in a small part of the sinusoidal voltage, namely in the zone of reaching the amplitude value, a barrier discharge occurs with the generation of ozone. Therefore, the efficiency ozone generators at sinusoidal voltage do not exceed 2%. When powered by a pulsed voltage, ozone generation occurs almost during the application of the entire voltage pulse; in addition, ozone generation also occurs in the pause between pulses, due to oscillatory processes in the pause between pulses. In addition to a significant increase in ozone yield, there is practically no process of heating the dielectric barrier.

The problem of optimization the modes of electrical networks pro- vides determination the optimal values of reactive power of sources, voltages of reference nodes and transformation ratios of controlled transformers. At pre- sent, methods and algorithms for optimization of reactive power and node volt- ages are sufficiently developed. However, the development of new efficient optimization algorithms of transformation ratios remains as a important topic. In this case, the issues of optimization of transformation ratios of transformers included in closed networks have a particular importance.

Investigation of the transient characteristics of S-diodes based on silicon compensated by vanadium
Authors: Shoyusupov Sh , Rakhmatullaev Sh , Shoyusupov Sh 
Published: December 2020

Abstract
To obtain more photosensitive S-diodes, silicon should be compensated for by impurities, which increase the photosensitivity of the original crystals. Diffusion of vanadium in silicon was carried out in evacuated or open quartz ampoules at a temperature of 900-1250 °C for 2-20 hours. Silicon wafers 0.5-1.0 mm thick and an alloying element of vanadium were placed in the ampoule. Usually used n-Si with ρ ~ 5 ÷ 200 Ω·sm and with a thickness of 0.2-0.5 mm. The concentration of deep levels introduced during diffusion was 1014 cm-3. The resistivity of silicon after diffusion increased to 103-104 Ω·sm at 300 K, and the diffusion length Ld decreased to 10-30 μm. S-diodes were made in a vacuum by melting aluminum and Au + 0.1% Sb alloy at 700 °C for 1 min. The contact area (S) is approximately 0.2 mm2, the base thickness d = 0.2-1.0 mm. Attitude d/Ld≈10 ÷ 100. Iincline ~ 1/tinclusion in a wide range of currents is linear, where Iincline> Ibre. Determined by the slope Iincline ~ 1/tinclusion the charge is Qcr = 3.52·10-9C. In this case, the average concentration of injected current carriers in the base is n = 5.44·1013 cm-3, which is in good agreement with the concentration of electroactive atoms V in Si, determined by capacitive methods. The dependence

Authors: Singh P 
Published: December 2020

Abstract
Blockchain is a way of passing data (such as records, events, or transactions) from one party to another in a very secure way. It is an electronic record of information that requires digital security. All data stored in the blockchain is immutable; once a piece of data enters into a blockchain, it is practically impossible to alter its value. The Blockchain has changed the model from a centralized way of traditional business to the decentralized model of the blockchain, that means there it can run without any central authority. It works on Peer to Peer Model rather than Peer-Mediator-Peer. The Blockchains makes the process easier, fastest, and trustworthy to deal with businesses as it follows Peer to Peer nature Blockchain. It has become the most used business model in different industries, such as construction industries, as it is the safest, fastest, transparent, and it also is more comfortable to implement. The critical feature of the blockchain that makes it today’s most potential technologies are: decentralized, self-control, peer- to- peer relationship, fixed record and time stamping. Thus, this chapter focuses on the pivotal role and application of BlockChain technology on the digitization of land records of the Indian Scenario.

Published: December 2020

Abstract
A brief overview of research work in the field of studying the wear resistance and surface strength of die tooling under cyclic loading is given. The peculiarities of deformation and the presence of a limit of physical endurance, which is associated with the course of dynamic deformation aging in metals (Cr,V) are considered. Relatively slow aging is observed under cyclic deformation conditions. The influence of saturation processes with pairs of elemental structure formed in metals with multilayer nanocoating is also considered. The work dedicated to the definition of wear resistance and improvement of die tooling is of great interest and requires a more in-depth study of this problem, thereby developing a new technique as a promising new direction in the automotive industry and mechanical engineering.

Published: December 2020

Abstract
The results of experimental studies of the model behavior under seismic effect in a centrifugal testing installation are given in the paper. The goal was to study the deformability and stability of slopes of a given configuration made of phosphogypsum and to substantiate the possibility of using phosphogypsum in erecting enclosing dams of sludge collectors located in seismic regions. The experiments on models are based on the centrifugal modeling method, which involves the change in gravity field of the model. The models were tested at a stabilized and unstabilized state of phosphogypsum. Models stabilization was achieved by centrifugation for 8-25 min. The model was considered stabilized when its deformation did not exceed 0.01 mm. In a stabilized state, a fragment of the dam slope made of phosphogypsum in a water-saturated state at a slope steepness m=2, m=3 and in a dry state at m=2 was investigated. In an unstabilized state, the models of dams made of phosphogypsum were studied in a water-saturated state with a slope steepness m=3, and a dam fragment at m=3 in a water-saturated state with horizontal and vertical sand drainage layers. As a result of studies of seismic stability of dam fragments made of phosphogypsum, the following was established: the overall stability of dams made of phosphogypsum (in a stable state) under seismic effect of up to 9-10 points is fully ensured both in a dry and water-saturated state. Horizontal and vertical interlayers increase the slope stability of the dam model made of phosphogypsum in a water-saturated state; the slopes were stable after a dynamic impact of 9 point even in unstabilized states. Drainage layers accelerate the consolidation of phosphogypsum, and this naturally increases the seismic resistance of dams.
