Essais de définition des vins blancs tachés et des vins rosés
Authors: SUDRAUD Pierre , BAR M. , MARTINIERE P. 
Published: August 2018

Si l'article premier du décret du 23 novembre 1967 a donné la définition générale du vin, il n'a toujours pas précisé les distinctions entre certains types de vins différent entre eux par la couleur; c'est ainsi que les dénominations vins blancs, vins rosés et vins rouges ne correspondent pas à des définitions précises et légales et par suite, n'ont qu'une valeur juridique limitée (sauf dans le cas des vins d'appellation d'origine et des vins délimités de qualité supérieure pour lesquels une liste de cépages est fixée par décret). Cependant ce problème est extrêmement important car certains traitements sont autorisés pour les vins d'une couleur donnée et interdits pour les autres et les prestations d'alcool vinique sont différentes en fonction du type de vin produit pour les appellations d'origine contrôlée. Cette question a d'ailleurs été mise à l'ordre du jour des travaux de la Commission de l'Institut technique du vin qui a proposé dans sa séance du 5 mars 1965 de définir les vins d'après leur couleur : M. RIVOYRE, directeur du Laboratoire départemental de la Saône-et-Loire à Mâcon, a rédigé un texte mettant en jeu des critères oenologiques et analytiques en vue de cette distinction et c'est à partir de ce texte que nous avons essayé de fixer une limite supérieure pour la teneur en anthocyanes des vins blancs tachés en fonction des traitements autorisés (décoloration par le charbon) et également de fixer des limites inférieures et supérieures de l'indice de permanganate, des anthocyanes, des leucoanthocyanes totaux et de l'intensité colorante pour les vins rosés.

<p align="justify">Pemenuhan kebutuhan terhadap listrik sangat tinggi dan memerlukan jaringan yang mampu menjangkau ke seluruh pelanggan. Jaringan untuk mendistribusikan listrik ke masyarakat sangat kompleks terdiri dari jaringan bawah tanah dan tiang-tiang serta tower. Bangunan tiang-tiang dan tower-tower tersebut sering menimbulkan masalah dalam pengunaan lahan karena memerlukan tempat yang cukup luas. Masalah penggunaaan lahan ini banyak timbul di daerah perkotaan karena semakin sulitnya lahan yang tidak terpakai dan harga lahan yang mahal. Salah satu lokasi yang mengalami permasalahan adalah di daerah Jalan Gatot Subroto Barat, Denpasar. Permasalahan yang terjadi di daerah ini adalah tower milik PLN yaitu tower SUTT 150 kV no.71 menghalangi jalan masuk ke lahan milik warga, sehingga harus melakukan rekayasa dinding penahan tanah dan pondasi dengan memotong sebagian tanah timbunan serta dinding penahan tanah tanpa mengurangi keamanan konstruksi tower SUTT. Untuk mengatasi masalah tersebut direncanakan suatu dinding penahan tanah dari tiang bor (<em>bored pile</em>) untuk mengganti dinding penahan tanah tipe gravitasi yang telah digunakan sebelumya. Sebelum dilakukan perhitungan perlu dilakukan penyelidikan kondisi tanah dasar di lokasi proyek sehingga dapat direncanakan dinding penahan tanah yang sesuai dan memadai. Setelah melakukan penyelidikan tanah di laboratorium dihasilkan nilai sudut geser tanah (ϕ) = 30º dan berat volume (γ) = 1,6 gr/cm<sup>3</sup> dan setelah melakukan analisis pada dinding penahan tanah diperoleh nilai momen maksimum (M maks) = 2384,248 kg.m dan gaya geser maksimum (D maks) = 1098,952 kg. Hasil perhitungan bahan dinding penahan tanah digunakan beton bertulang dinding susunan bored piled diameter 40 cm dengan kedalaman pancang 4,5 m dari tanah eksisting dan tinggi dinding penahan tanah 3,5 m diatas tanah, sehingga dibutuhkan struktur beton bertulang tiang bor (<em>bored piled</em>) panjang 8 m sebanyak 35 buah. Struktur beton bertulang bored piled diameter 40 cm menggunakan tulangan utama longitudinal 6D16 (6 buah besi ulir dengan diameter 16 mm) dan tulangan geser menggunakan Ø10-250 (besi polos diameter 10 mm dengan jarak 250 mm). Luas lahan baru yang didapatkan akibat pengurangan eksisting 10,20 x 13,10 m<sup>2</sup> menjadi 5,2 x 6,3 m<sup>2</sup>, di bagian utara (depan) diperoleh lahan sebesar 5,0 x 11,7 m<sup>2</sup> dan jalan akses di bagian timur dari 2,5 m menjadi 3,9 m.</p>

<p class="DRAbstrak">Cost estimation is the art of estimating the amount of cost required for an activity based on available information. The conceptual cost estimate is an early stage in planning a construction project. This estimate provides the cost that must be budgeted for a construction project. Cost conceptual estimates have low accuracy because the time of calculation and available information is limited. This study aims to obtain a conceptual model of the conceptual cost of short-spaced bridges. The method used is the cost index. The cost index is a figure indicating the cost per m2 of bridges at a given time. The required data are contract documents and drawings design that are built in 2012 - 2015 in Banyumas residency area. Span of bridge 4 - 38.8 meters and width of bridge 2 - 7 meters with caisson foundation. The data were obtained from Dinas Bina Marga and Public Works Agency. The results showed that the conceptual cost model of reinforced concrete bridge with caisson foundation was BJiL = (100.540.56t2-404.528.636,58t + 406.914.286.088,58) x P x W, with t = year, P = span bridge, and W = bridge width.

Algorithms for Solving Boundary Value Problems of Deformable Solid Mechanics in View of Creep Strain
Authors: Stankevich I. V. , Volkov S. S. 
Published: August 2018

Further development of power and, primarily, engine engineering is associated with significantly increasing specific indicators. For example, the main trend in development of gas turbine engines is to increase gas parameters before the turbine. At the same time, there is an intensive growth of thermal and mechanical tension, and first of all this applies to the parts and components of the flow range. The destruction of these structural elements may have grave consequences. Increasing reliability and durability of responsible components of engines under operating conditions of complex cyclic thermo-mechanical loading is one of the priority tasks of modern engine engineering.One of the factors to determine a design performance is high-temperature creep. When solving the problems of deformable solid mechanics (DSM) in terms of creep, various options of the theory of hereditary creep and three main technical theories of aging, flow and hardening are widely used. There are also theories known that use an apparatus of the structural models and mechanical analogues to describe the creep. Most theories satisfactorily describe the creep strain under constant or slowly changing loads. Analysis of stress-strain states under variable loads is better described by the theories of flow and hardening, and the theory of hardening has some advantages over the theories of flow, as it gives more exact approximation for experiment results. From the point of view of the computing cycle arrangement, the technical theories have well-known advantages over the hereditary ones.When using the finite element method (FEM) to solve the boundary value problems of DSM considering the creep strain, an explicit or implicit Euler scheme is very often used. Depending on the features of the problem under consideration, a solution algorithm is constructed either in accordance with the method of initial stress, or by the method of initial strains. The method of initial strains when solving the problems in terms of creep is used more often, because the application of an initial stress method for this class of problems is technically much more complicated. The paper examines the explicit and implicit Euler schemes in combination with FEM. Both schemes are formulated in accordance with the method of initial strains. A constitutive relation was chosen in the form of the theory of flows.
Evolutionary Operators for Global Optimization Population-Based Algorithms. Experience of Systematization
Authors: Karpenko A. P. 
Published: August 2018

There are a large number of examples of using the population-based algorithms (P-algorithms) to have a successful solution for complex practical tasks of global optimization, for instance, problems of computer-aided design, synthesis of complex chemical compounds, optimal control of dynamic systems, etc. P-algorithms are also successfully used in multi-criteria optimization, when a preliminary construction of some Pareto set (front) approximation is required. P-algorithms are numerous and very diverse – over 100 such algorithms are known, and new algorithms continue to appear. In this connection, the problem of systematizing expressive means of P-algorithms is of relevance. We consider one of the components of this problem that is the problem of classification of the search operators of P-algorithms.The paper formulates a global optimization problem and a general scheme of the P-algorithms to solve it. This multilevel classification of the main search operators of P-algorithms at the highest level of the hierarchy identifies the following operators: initialization of the population and the end of the search; coding of individuals; randomization; selection; crossing; population management; local search.These operators at the next hierarchical level are divided into deterministic and stochastic ones. Further, we distinguish static, dynamic program and dynamic adaptive operators. The following classification levels are "operator dependent", that is, generally speaking, different for each operator. We reveal the essence of these operators and give the use cases in various P-algorithms.Although the paper uses the names of operators such as selection, crossing, our orientation is not only to evolutionary algorithms. A description scheme of operators presented in this paper can be used to determine any population-based algorithms.The work development expects extending a set of operators presented, and, above all, using this set and a set of basic essences of population algorithms, the formalization of which was earlier proposed by the author, systematizing the most known algorithms of this class.
Anisotropic Half-Space Temperature Field with its Moving Boundary Being under Local Pulse-periodic Heat Action in Heat Exchange Conditions with External Environment
Authors: Attetkov A. V. , Volkov I. K. 
Published: August 2018

A noticeably raising interest in analytical research methods in the mathematical theory of the thermal conductivity of solids [1-3] was initiated by various causes, among which, as the most significant, special mention should go to the widespread practical engineering application of computer technology, mathematical modelling techniques and anisotropic materials of various origin. At present, the "anisotropic section" [3, 4] holds a most unique position in the mathematical theory of the thermal conductivity of solids, due both to the specificity of the mathematical models used in it, and to the fair-minded development need in fundamentally new high-performance and absolutely stable computational methods [4-6] to solve real, practically important engineering tasks.The spectrum of practical use of solutions to problems of the mathematical theory of the thermal conductivity, presented in an analytically closed form, is quite wide. In particular, such solutions are used to test new computational algorithms, and the problems generating these solutions are called test problems. And if in the traditional sections of the mathematical theory of the thermal conductivity a set of test problems is very extensive [1-3, 7], then test problems of the "anisotropic thermal conductivity" in regions with fixed and moving boundaries are inconsiderable in number [4, 8-14].The main objective of the research is to solve the problem of determining the temperature field of an anisotropic half-space, the boundary of which moves linearly and is subject to local pulse-periodic thermal action under conditions of heat exchange with the external environment.
Research of New Criteria for Detecting First-order Residuals Autocorrelation in Regression Models
Authors: Bazilevsky M. P. 
Published: August 2018

When estimating regression models using the least squares method, one of its prerequisites is the lack of autocorrelation in the regression residuals. The presence of autocorrelation in the residuals makes the least-squares regression estimates to be ineffective, and the standard errors of these estimates to be untenable. Quantitatively, autocorrelation in the residuals of the regression model has traditionally been estimated using the Durbin-Watson statistic, which is the ratio of the sum of the squares of differences of consecutive residual values to the sum of squares of the residuals. Unfortunately, such an analytical form of the Durbin-Watson statistic does not allow it to be integrated, as linear constraints, into the problem of selecting informative regressors, which is, in fact, a mathematical programming problem in the regression model. The task of selecting informative regressors is to extract from the given number of possible regressors a given number of variables based on a certain quality criterion.The aim of the paper is to develop and study new criteria for detecting first-order autocorrelation in the residuals in regression models that can later be integrated into the problem of selecting informative regressors in the form of linear constraints. To do this, the paper proposes modular autocorrelation statistic for which, using the Gretl package, the ranges of their possible values and limit values were first determined experimentally, depending on the value of the selective coefficient of auto-regression. Then the results obtained were proved by model experiments using the Monte Carlo method. The disadvantage of the proposed modular statistic of adequacy is that their dependencies on the selective coefficient of auto-regression are not even functions. For this, double modular autocorrelation criteria are proposed, which, using special methods, can be used as linear constraints in mathematical programming problems to select informative regressors in regression models.
Mathematical Modeling of the Contact Interaction of Two Elastic Bodies Using the Mortar Method
Authors: Stankevich I. V. , Aronov P. S. 
Published: August 2018

The article discusses the development of an algorithm for solving contact problems of elasticity theory. Solving such problems is often associated with necessity of using mismatched grids. Their joining can be carried out both with the help of iterative procedures that form the so-called Schwarz alternating methods, and with the help of the Lagrange multipliers method or the penalty method. The algorithm constructed in the article uses the mortar method for matching the finite elements on the contact line. All these methods of joining the grids make it possible to ensure continuity of displacements and stresses near the contact line. However, one of the main advantages of the mortar method is the possibility of independent choice of different types of finite elements and form functions both on both boundaries of two bodies on the contact line, and when integrating along it. The application of this method in conjunction with the classical formulation of the finite element method based on the minimization of the Lagrange functional leads to a system of linear algebraic equations with a saddle point. The article discusses in detail its numerical solution based on the modified symmetric successive upper relaxation method.The results of the constructed algorithm are demonstrated on three test contact problems. They analyze the stress-strain state of differently loaded contacting two-dimensional plates. The examples considered show that continuity of the displacements of displacements and stresses is preserved near the contact line. The versatility of the developed algorithm leaves the possibility of further analysis of the effectiveness of the mortar method using different types of finite elements and form functions.
Polynomial Solutions of the Dirichlet Problem for the Tricomi Equation in a Strip
Authors: Algazin O. D. 
Published: August 2018

In the paper we consider the Tricomi equation of mixed type. This equation is elliptic in the upper half-plane, hyperbolic in the lower half-plane and parabolically degenerate on the boundary of half-planes. Equations of a mixed type are used in transonic gas dynamics. The Dirichlet problem for an equation of mixed type in a mixed domain is, in general, ill- posed. Many papers has been devoted to the search for conditions for the well-posednes of the Dirichlet problem for a mixed-type equation in a mixed domain.This paper is devoted to finding exact polynomial solutions of the inhomogeneous Tricomi equation in a strip with a polynomial right-hand side. The Fourier transform method shows that the Dirichlet boundary value problem with polynomial boundary conditions has a polynomial solution. An algorithm for constructing this polynomial solution is given and examples are considered. If the strip lies in the ellipticity region of the equation, then this solution is unique in the class of functions of polynomial growth. If the strip lies in a mixed domain, then the solution of the Dirichlet problem is not unique in the class of functions of polynomial growth, but it is unique in the class of polynomials.
