On the Assessment of Actual Compressive Strength of Concrete in Reinforced Columns: Influence of Core Diameter and Slenderness Ratio
Authors: Benidir Adel , Debbakh Said , Chaibeddra Siham 
Published: January 2024

Abstract
This paper studies the influence of core diameters and slenderness ratio on the assessment of the actual compressive strength of concrete on reinforced-concrete elements. The experiment consists of the preparation of three reinforced concrete columns and the extraction of cores to carry out both destructive (core diameter of 64 mm, 79 mm, and 103 mm) and non-destructive tests. The non-destructive test deals with the propagation of elastic and compressive waves by deriving the ultrasound pulse velocities. The results show that the assessment of the compressive strength of concrete depends strongly on the diameter of cores and the extraction zones. Furthermore, the derivation of the actual compressive strength by referring to the compressive strengths of the cores with a diameter of 64 mm shows a stringent appearance of a size effect. More interestingly, valuable details about the correlation between the concrete compressive strength assessment based on destructive and non-destructive tests are also presented.
Impact of Passive Design Strategies on Environment, Cooling and Lighting Energy Demand. A Weighted Least Squares-Based Approach
Authors: Boukarta Soufiane 
Published: January 2024

Abstract
The energy transition requires optimal knowledge of the thermal behaviour of different passive strategies. This paper explores the impact of 28 variables representing 4 shading devices, 5 external wall compositions (U
w), 3 window types (U
w), 4 window-to-wall ratios (WWR), 4 types of climates represented by 4 cities, and 8 orientations. Applying the Latin hypercube sampling method, a campaign of 300 dynamic thermal simulations is performed to assess the impact of the variables selected using the weighted generalised linear regression method for the energy demand for air conditioning, the energy demand for lighting, and the environmental impact expressed in kg of CO2. The model of energy demand for cooling (R² = 0.951) shows that the weather data is the variable that most explains energy demand, followed by the glazing ratio, the thermal characteristics of external walls, and shading devices. The model explaining the energy demand for lighting (R² = 0.945) shows that the WWR and shading devices, the weather data, and the orientation, influence the energy demand for lighting. Finally, the model explaining the embodied carbon footprint (kg of CO2) (R² = 0.989) shows that external walls and window type are the main influencing factors. Finally, the best combination for balancing the cooling-lighting-embodied carbon balance equation is discussed.

L’espace urbain chez Rodrigo Sorogoyen : un décadrage politique du regard
Authors: LEVET Natacha 
Published: January 2024

La production de Rodrigo Sorogoyen investit l’espace urbain madrilène dans un cinéma de genre – le néo-noir espagnol – qui en fait non seulement un terrain d’exploration de la criminalité contemporaine mais aussi une métonymie des dysfonctionnements sociaux et politiques de l’Espagne. Le réalisateur use de la tension entre cadrages et décadrages pour déplacer l’attention du spectateur, et charger l’intrigue criminelle de ses films d’une analyse politique, les deux se rejoignant finalement dans le cadre urbain de la caméra. Trois films ou séries seront le support de cette étude : Que Dios nos perdone, El Reino, deux longs-métrages, et Antidisturbios, série en six épisodes.
Estimating distributions from samples with random size
Authors: Тихов Михаил Семенович 
Published: January 2024

Статья посвящена задаче оценивания функции распределения и предельного поведения расстояния между эмпирическим и теоретическим законами, именно, суммируемых квадратичных уклонений и статистики Смирнова и Колмогорова по выборкам случайного объема. Мы предполагаем, что этот случайный объем имеет обобщенное отрицательное биномиальное распределение и как случайная величина не зависит от исходной выборки. Найдены предельные распределения для суммируемых квадратичных уклонений ядерных оценок функции распределения по выборкам случайного объема. Показано, что для выборок случайного объема предельное распределение статистик Смирнова и Колмогорова имеет более тяжелые хвосты, чем у функции распределения Вейбулла и Колмогорова в случае выборок фиксированного объема. Мы предлагаем подход на основе асимптотического разложения, чтобы естественным образом сбалансировать асимптотическое распределение и случайный объем выборки. Рассмотрена также задача последовательного оценивания параметра сдвига равномерного распределения. Отрицательное биномиальное распределение (объем выборки $\nu $) возникает здесь естественным образом в результате статистического эксперимента по выполнению серии независимых испытаний.
The article is concerned with the estimating problem of a distribution function and the limiting behavior of the distance between the empirical and theoretical laws, namely, integrated square errors and Smirnov and Kolmogorov statistics by the samples with random size. We suppose that this random size and the initial sample are independent random variables and this random variable has the generalized negative binomial distribution. We find limiting distributions for integrated square errors of kernel distribution function estimators by the samples with random size. It is shown that for samples with random size the limiting distribution of the Smirnov and Kolmogorov statistics has more heavier tails than the Weibull and Kolmogorov distribution function for samples with the fixed size. We propose an asymptotic expansion approach to naturally balance the asymptotic distribution and random sample size. The problem of sequential estimation of the shift parameter of the uniform distribution is considered. The negative binomial distribution (samples size $\nu $) arises naturally here from a statistical experiment of performing a series of independent trials.

Authors: Бенинг Владимир Евгеньевич 
Published: January 2024

В работе рассмотрено асимптотическое поведение резерва организации, подверженной риску в случае, когда число факторов, приводящих к убытку, случайно. Рассмотрено конкретное рапределение убытков, близкое к распределению Бёрра. Проведено асимптотическое сравнение деятельности таких организаций в терминах необходимого добавочного числа таких факторов. Рассмотрены два примера, иллюстрирующие полученные результаты. Первый пример касается максимальных потерь, а во втором примере рассматриваются усечённые биномиальное и распределение Пуассона, описывающие число случайных факторов, приводящих к потерям.
The paper considers the asymptotic behavior of the reserve of an organization subjected to risk in the case when the number of factors leading to loss is random. Burr distribution is considered as loss distribution. An asymptotic comparison of the activities of such organizations is carried out in terms of the necessary additional number of such factors (asymptotic deficiency). Two examples illustrating tne obtained results are presented. The first example concerns extreme order statistics, and the second one deals with the truncated Poisson and binomial distributions.

В статье исследуется задача целераспределения в системе воздушно-космической обороны (ВКО). Для более адекватной оценки эффективности работы средств поражения введено возможностно-вероятностное представление вероятности перехвата цели, позволяющее учитывать их взаимное положение. Разработана математическая модель рассматриваемой задачи. Осуществлена редукция построенной модели к задаче целочисленного линейного программирования, учитывающей эшелонированный характер системы ВКО. Предложенный подход обеспечивает оптимальное распределение ресурсов при совместной работе средств поражения.
The paper studies the problem of target allocation in the aerospace defense system. For a more adequate assessment of the effectiveness of means of destruction, a fuzzy (possibilistic) representation of the interception probability is introduced, which makes it possible to take into account their mutual position. A mathematical model of the problem under consideration is developed. The model is reduced to an integer linear programming problem, taking into account the echeloned nature of the aerospace defense system. The proposed approach ensures optimal resource allocation when the means of destruction work together.
Technical parameters analyses of different types of impact-vibration soil compacting machines
Authors: Tyuremnov I. S. 
Published: January 2024

Introduction. Impact-vibration machines, which perform soil compaction with periodic removal of the working body from the ground, are the most common for mechanization of soil compaction in road construction: self-propelled non-reversible and reversible vibratory plates, vibratory rammers, mounted excavator vibratory plates, trench vibratory rollers and soil vibratory rollers. It is necessary to analyze the main technical characteristics of impactvibration machines of different types in order to assess the possibility of developing a mathematical model of soil compaction, combining several types of impact-vibration machines at once.Materials and methods. The technical characteristics of different types of impact-vibration machines for the analysis: 342 models of non-reversible self-propelled vibratory plates; 312 models of reversible self-propelled vibratory plates; 311 models of vibratory ground rollers; 63 models of mounted vibratory plates for excavators; 24 models of vibratory rammers and 21 models of trench vibratory rollers are used. The machine mass (for vibratory plates of different types) or the mass per compaction module (for vibratory rollers of different types) was taken as a main parameter.Results. The graphical dependencies have been obtained. They illustrate that for the given types of shock-vibration machines the excitation force, relative excitation force and oscillation frequency are located on mutually contiguous and continuing parts of curves. This is a common pattern: as the mass of the machine increases, the excitation force increases, but the relative excitation force and frequency of oscillation decrease. Vibratory rammers are out of this general pattern, because at comparable weight they have significantly lower frequency of oscillation (9...12 Hz) and high amplitude (50...75 mm). Also, the mounted excavator vibratory plates stand out from the general pattern, having a smaller range of vibration frequencies for machines of similar weight, moreover, they perform soil compaction positionally, and not in the process of movement at a certain speed, as other impact-vibration machines.Discussion and conclusions. The common pattern of changes in the main technical characteristics of selfpropelled non-reversible and reversible vibratory plates, trench rollers and soil vibratory rollers at close nominal amplitude of their vibrations gives grounds for the development of a unified theoretical description of the interaction of the working bodies of these types of machines with the compacted soil and a common method of calculating the influence of technical characteristics and operating modes of these machines on the results of soil compaction.

Authors: Pashukevich S. V. 
Published: January 2024

Introduction. During the operation of heavy-duty diesel equipment in areas with a low-temperature climate, engine oils are contaminated by coolant and water. The ingress of these substances into the lubricant leads to a deterioration in its quality indicators, which subsequently leads to problems in the nodes of the internal combustion engine.Relevance. The deterioration of the values of engine oil quality indicators is directly related to the presence of water and coolant in it. It is not always possible to objectively track the ways of leakage of these pollutants, and this, in turn, leads to serious consequences in the form of wear of the contacting surfaces of engine parts, corrosion. It is also important to evaluate the resource of lubricant additive packages due to its dilution with water and antifreeze.Materials and methods. This paper presents the results of a literature review aimed at studying the ways of coolant and water ingress during the operation of diesel engines, their influence on the physical and chemical properties of motor oils. The brief information about the composition of the coolant is indicated.Conclusions. The ingress of water and coolant into the engine oil leads to an increase in the kinematic viscosity of the lubricant, as well as to the formation of deposits on the surfaces of the engine friction pairs. In addition, spherical compounds appear in the crankcase of the engine, which are a combination of destroyed additive packages and glycol. Oil change intervals must be monitored at an increased rate of water and coolant entering the engine oil.Scope of the study / possibility. This type of study will help to determine the causes of penetration of water and coolant into the crankcase space, to understand the consequences of using engine oil contaminated with water and coolant.Originality / value. The conducted research can be the basis for the development of recommendations for improving the maintenance of internal combustion engines for enterprises that have at their disposal cars with diesel engines in order to increase the resource of power units and reduce operating costs.

The developed algorithm for forming a complex flow graph in the form of a flowchart and a DIM is presented.Results. The use of the method is considered on the examples of structuring the elements of the object and technological processes at the stage of work production by the contracting organization, taking into account different options and schemes for organizing the work of specialized streams. The design results are presented in the form of a calculation matrix, a cyclogram and a Gantt graph in the MS Project program.Discussion and conclusion. The development of the basic information for the model of the calendar plan for the construction of a road at different stages of design in an integrated general data environment is presented. The use of linear road is justified. zoning as a method of decomposition of a linear object at the stages of CAD, POS and work production by the contracting organization. The structural elements of the design at the final stage (work production by the contracting organization) are linear design and technological modules and specialized flows formed on the basis of maps of labor processes of the contracting organization.
