Comparing Metrics for Scenario-based Robustness Assessment of Building Performance
Authors: Walker Linus , Kuhn Alexandra , Hischier Illias , Schlueter Arno 
Published: November 2021

Abstract
To decrease greenhouse gas emissions of the Swiss building stock, effective retrofit strategies are necessary. Due to the long-term operation of buildings, future developments and uncertainties need to be considered, which calls for assessing the robustness of retrofit decisions. Existing studies propose robustness metrics for decisions under deep uncertainty to be coupled with a scenario-based simulation approach. We review these metrics and present a simulation approach that includes current and future operational energy, emissions, and costs. We apply the seven identified metrics to retrofit decisions of a multifamily house located in Zurich, where future scenarios in terms of climate, occupancy, decarbonization, and cost development are included. The metrics are based on different assumptions and positions towards risk. We further find that the discriminatory power is different, confirming the Minimax Regret metric to be most suitable for the building context when looking at individual buildings. For the case study, we find that deep retrofit seems to be a robust decision from an environmental perspective. From a cost perspective, the electrification of the heating system with heat pumps and the installation of PV without a complete envelope retrofit proves to be most robust.

Published: November 2021

Abstract
The building construction industry is adapting Additive Manufacturing (AM) and robotic fabrication techniques to, among other efficiency and cost benefits, reduce the lifecycle Green House Gas (GHG) emissions of new buildings. This research aims to fabricate a low- GHG emission façade by encoding environmental performance using a combination of material selection, AM techniques, and bespoke geometry. This paper presents the design methodology, specifically the response to solar radiation (i.e. shading and daylight transmission). The key contribution of this publication is establishing the digital fabrication process of AM facades: beginning with performative parametric design, using empirical Bi-directional Scattering Distribution Function (BSDF) data of AM thermoplastic elements for daylight simulation to assess performance, and finally optimising the topology for a specific context (location and orientation).
Relic gravitational waves in cosmological models based on the modified gravity theories
Authors: Fomin I V , Chervon S V 
Published: November 2021

Abstract
We consider cosmological models based on the generalized scalar-tensor gravity, which correspond to the observational constraints on the parameters of cosmological perturbations for any model’s parameters. The estimates of the energy density of relic gravitational waves for such a cosmological models were made. The possibility of direct detection of such a gravitational waves using modern and prospective methods was discussed as well.
The field-theoretical methods in Lovelock gravity
Authors: Petrov A N 
Published: November 2021

Abstract
The field-theoretical methods are used to construct conserved currents and related superpotentials for perturbations on arbitrary backgrounds in the Lovelock gravity. The perturbations are considered as a dynamic field configuration propagating in a given spacetime. The field-theoretical formalism is exact (without approximations) and equivalent to the original metric theory. As Lagrangian based formalism, it allows us to apply the Noether theorem. As a result, we construct conserved currents and superpotentials, where we use arbitrary displacement vectors, not only the Killing ones or other special vectors. The developed formalism is checked in calculating mass of the Schwarzschild-anti-de Sitter (AdS) black hole. The new formalism is adopted to the case of a so-called pure Lovelock gravity, where in the Lagrangian only a one polynomial in Riemannian tensor presents. We construct conserved charges and currents for static and dynamic black holes of the Vaidya type with AdS, dS and flat asymptotics. New properties of the solutions under consideration have been found. The more results are discussed. The first section in your paper
Decrease of the effective cosmological constant in the Poincare gauge theory of gravity with a scalar field
Authors: Babourova O V , Frolov B N 
Published: November 2021

Abstract
Cosmological consequences of the Poincare gauge theory of gravity are considered. An effective cosmological constant depending from the Dirac scalar field is introduced. It is proved that at the super-early Universe, the effective cosmological constant decreases exponentially from a huge value at the Big Bang to its extremely small value in the modern era, while the scale factor sharply increases and demonstrates inflationary behavior. This fact solves the well-known “cosmological constant problem” also in the Poincare gauge theory of gravity.
Null shells and double layers in quadratic gravity
Authors: Ivanova I D 
Published: November 2021

Abstract
For a singular hypersurface of arbitrary type in quadratic gravity motion equations were obtained using only the least action principle. It turned out that the coefficients in the motion equations are zeroed with a combination corresponding to the Gauss-Bonnet term. Therefore it does not create neither double layers nor thin shells. It has been demonstrated that there is no “external pressure” for any type of null singular hypersurface. It turned out that null spherically symmetric singular hupersurfaces in quadratic gravity cannot be a double layer, and only thin shells are possible. The system of motion equations in this case is reduced to one which is expressed through the invariants of spherical geometry along with the Lichnerowicz conditions. Spherically symmetric null thin shells were investigated for spherically symmetric solutions of conformal gravity as applications, in particular, for various vacua and Vaidya-type solutions.
Quantum Nonlocality - Possible Cosmophysical Effects
Authors: Mayburov S N 
Published: November 2021

Abstract
Mutiple experimental results indicate the existence of cosmophysical effects which influence parameters of nuclear decays and chemical reactions in lab. conditions. In particular, variations of nucleus decay parameters are detected which amplitudes are of the order 10−3 and periods of one year, 24 hours or about one month. Similar influence of solar activity on nuclear decays and chemical reactions also was reported. We argue that such deviations from radioactive decay law and other similar effects can be described by novel quantum nonlocality mechanism, different from standard EPR-Bohm nonlocality. Modified Doebner-Goldin model applied for the description of dynamical nonlocal effects concerned with nuclear decays.
From Photon to Oganesson: Lie Algebra Realization of the Standard Model Extending over the Periodic Table
Authors: Trell Erik 
Published: November 2021

Abstract
As reported in a series of previous PIRT conferences, a direct SU(3) structural realization of the Standard Model has been developed based upon Marius Sophus Lie’s original Norwegian Ph.D. thesis Over en Classe Geometriske Transformationer from 1871 (and thus due for a most deserved 150-year anniversary). It elucidates how “the theory of main tangential curves can be brought back to that of rounded curves”, anticipating a coherent linear representation of the elementary particles instead of the rotational chosen since they were considered point-like and amorphous when they many years later entered the stage. Under these premises the Standard Model has built a magnificent, undoubtedly true but congested multi-particle system whereas the Lie continuous transformation element, the partial derivative ’straight line of length equal to zero’ outlines an isotropic vector matrix lattice of crystallographic Killing root space diagram A3 form which from the Nucleon and inwards can backtrack the Standard Model geometrically, as well as continue outward iterating to a space-filling solid state R3×SO(3) wave-packet complex tessellating the whole periodic table with electron shells and subshells, isotope spectrum, neutron captures, radiative channels, oxidation states, molecular binding sites etc. in successive layers also including the Lanthanides in the sixth period and the Actinides in the seventh, in which now the concluding Oganesson has been reached in perfectly well-built saturated noble gas shape and condition.
Method of multiple scales in scalar field cosmology
Authors: Zhuravlev V M , Chervon S V 
Published: November 2021

Abstract
In this work, the method of multiple scales is applied to analysis of cosmological dynamics. The method is used to construct solutions to the dynamic equations of the Universe filled with a scalar field in the Friedman-Robertson-Walker metric. A general scheme is described for choosing small dimensionless parameters of the expansion of model functions and applying the method itself to the equations of cosmological dynamics. Solutions are given that are constructed for two different types of a small parameter - a small field value and a small slow roll parameter.
Physics learning based on the use of concept maps
Authors: Pabón-Galán C A , Hernández-Suarez C A , Paz-Montes L S 
Published: November 2021

AbstractConcept maps are graphic learning tools that allow teachers and students to organize, represent knowledge, and visualize the relationships between concepts to promote understanding of physics. This study describes an innovative experience based on the development of concept maps with the aim of analyzing the perception of students in a teacher training program in natural sciences and environmental education at a public university in Colombia. The research subjects were 24 students studying basic physics who used concept maps for learning, and the data were analyzed quantitatively using a non-experimental design. The results show that the trainee teachers learned to elaborate concept maps, valuing very positively their educational applications to improve learning. It is concluded that concept mapping can be used to increase students’ understanding and motivation which should help to improve their academic performance.
Physical-mathematical model for determination of variation of internal forces in the simplified analysis of a beam
Authors: Márquez Peñaranda J F , Cáceres Rubio J R , Palacios Pabón J D 
Published: November 2021

Abstract
Springs are often taught in subjects of physics such as statics and solid mechanics belonging to civil engineering programs and mechanical engineering. This knowledge can be applied successfully in the modeling of structures and the consequent development of structural analysis. This paper presents the results of an investigation on physic-mathematical models which uses springs to replace complex connective conditions attempting to simplify the structural analysis process. The work focuses on the analysis of beams supported upon masonry walls, applying variations to the span lengths, sections and loads on them and considering realistic variations of the stiffness conditions required in the supports to meet the demands that these variations impose. For this, continuous beams with two spans with three types of section that are supported by walls that support different levels of restriction from different heights of the building of which they are part are modeled. It is concluded that there is an important influence of the slenderness of the beams and the degree of confinement of the supports upon the precision of the simplified model.
BKP tau-functions as square roots of KP tau-functions
Authors: van de Leur Johan 
Published: November 2021

Abstract
It is well-known that a B type Kadomtsev–Petviashvili (BKP) tau-function is the square root of a certain Kadomtsev–Petviashvili (KP) tau-function, provided one puts the even KP times equal to zero. In this paper we compute for all polynomial BKP tau-function its corresponding KP ‘square’. We also give, in the polynomial case, a representation theoretical proof of a recent result by Alexandrov, viz that a Korteweg–de Vries (KdV) tau-function becomes a BKP tau-function when one divides all KdV times by 2.
A Weld Line Detection Method Based on 3D Point Cloud for Automatic NDT
Authors: Dong Zhaoxuan , Huang Jianchang , Yin Shiqi , Fei Yuenong 
Published: November 2021

Abstract
The quality of welding is often checked by ultrasonic waves. Manual testing is costly and inefficient, and manual testing is not possible in some extreme environments. Automatic non-destructive testing (NDT) technology uses robots to carry ultrasonic devices for automatic detection. Machine vision is one of the important methods to achieve navigation, that is, capturing the weld line through the camera, planning the optimal path through visual analysis and processing, and also based on structured light. Although the navigation method can solve the problem of rust and stain to a large extent, it is less robust in dealing with problems such as rust, light interference and stain. This paper proposes a navigation method based on 3D point cloud, which can effectively improve its robustness.

Authors: Podhurenko V , Kutsan Yu , Terekhov V 
Published: November 2021

Abstract
The choice of wind turbines to fit various specific wind conditions for the purpose of ensuring maximum generation of electric power at least investment expenditures is among the wind power sector overarching challenges. Solving this task involves the evaluation of cost indices for wind turbines of various sizes. A well-known and rather popular with investigators model, made by the National Renewable Energy Laboratory (USA) has been improved for the first time with the aim of determining the cost of wind turbines of various sizes on the basis of their main parameters (rated power, rotor diameter, hub height) for current conditions of application. The established correlation relationships between the cost of wind turbine and its main parameters made possible the transformation of a well-known complex model into a model with linear equations and minimization of computations. Based on the research studies of the evolution of wind turbines main parameters and an average (global) cost of 1 MW of their power, the authors have suggested the first-ever original linear mathematical models that enable evaluating the wind turbine cost for any year of research. In illustration of application of the first ever developed technique, we have made the assessment of operating efficiency of the US wind farms from 2010 to 2019. The results obtained convincingly indicate the high quality of the developed model.

Published: November 2021

Abstract
The article conducted a study on approaches to the strategy of sustainable development of transport systems on the example of air transport in Ukraine. The shortcomings of the main tool of their strategy, namely the methods of classical forecasting, which limit its application, are revealed. The methods of forecasting based on expert judgment and classical methods of forecasting containing congenital pathology of errors are considered. Therefore, long-term factors and trends are identified, which remains a classic forecast, rather than building long-term forecasts of the national economy. To implement the stage of strategic planning of transport systems used the concept of sustainable development, which includes stages of identification through integrated assessment in the measurement of safety and strategy by defining goals, building the desired trajectory and decomposition of integrated indices through adaptive control methods of management theory. Three scenarios for the development of air transport in Ukraine have been developed: realistic - 3.8%; optimistic -7.0% and balanced - increase in gross value added (GVA) by 11.7% with scientific substantiation of quantitative values of indicators and key macroeconomic indicators, which guarantees the desired trajectory of sustainable development, and monitoring their implementation determines the effectiveness of public policies and actions.

Abstract
The issues of ensuring the ecological safety of the region`s population are actualized in the context of the growth increasing in the natural resources, accompanied by the increase in anthropogenic pressures on the environment and humans, aggravation of environmental problems, deterioration of the life quality and environmental conditions of activity in the region. The aim of the study is to develop the theoretical foundations for ensuring the ecological safety of the population of the region on the basis of a logistic-activity approach to its formation in the context of legal regulation of the environmental management process as a factor in achieving sustainable development goals and increasing energy efficiency.Using the methods of economic and mathematical modeling it is substantiated the existence of the relationship between the level of ecological safety of the region’s population and the amount of the funds from the budget allocated to finance environmental programs. Improving the legal regulation of the processes of ensuring the ecological safety of the region’s population for optimizing the budget expenditures for the implementation of environmental programs will create the conditions for realizing the economic potential of the region’s development, increasing the level and quality of life of the population.

Published: November 2021

Abstract
The purpose of the article is to decide the possibilities of Ukrainian financial security management in the conditions of military and political instability through adaptation of the indicators for the current methodology of the state financial security calculating in order to achieve the goals of sustainable development. The authors use general scientific and special methods, in particular dialectical, abstract logical, system analysis, economic and statistical. The authors in terms of the system approach and the allocation of material and information basis consider financial security. The authors formalize the process of informational support for the management of state financial security. Analysis of statistical data suggests that the determination of the Ukrainian financial security takes place because of political and military instability. Every component of financial safety includes factor of war influence, which as a result correlates the integral index of financial safety. The authors investigate factors that include expenditures for army forces support, aggressor state exchange rate expenditures, volume of monetary mass of the aggressor state in national economics, participation of the aggressor state capital in the banking capital structure, volume of financial resources loss of the aggressor-state.
