L’Emergy est définie comme la somme de toutes les formes d’énergie (énergie directe et indirecte, renouvelable et non-renouvelable) nécessaire à la réalisation d’un service ou d’un produit. La méthode d’évaluation Emergy est une méthode d’analyse quantitative qui détermine la valeur non-monétaire et monétaire des ressources, des services et des produits dans une unité commune : l’Emergy solaire. Cette méthode apparaît comme intéressante pour évaluer les agro-écosystèmes et identifier des leviers d’action pour la conception de systèmes plus durables. Cet article présente les concepts de la méthode Emergy en explicitant les notions clés telles que la transformité, le diagramme de hiérarchisation de l’énergie et les indicateurs Emergy. Ces notions sont explicitées en se basant sur l’exemple d’une analyse de la production de poissons en étang. Enfin, l’article détaille les applications possibles de la méthode pour les systèmes agricoles et notamment en production animale.

AbstractStarting from the concept and definition of littera in the Grammar treatises of the Late Antiquity and the Early Middle Ages, the contribution analyzes common graphic elements which were used by the scribes to create initials, ornamental patterns and the layout of the manuscript page. These elements and their functions were partly described in encyclopaedic works, e. g. of Isidor of Sevilla and Martianus Capella in the chapters about Geometry. Not only were these features well known through the study of the Artes, they also represented useful tools for the invention and production of medieval diagrams.

Research has been conducted to improve the efficiency of agricultural production by choosing technology and technical equipment based on a mathematical model, taking into account the peculiarities of location and production conditions of a farm. The limiting factors of the development of grain production are highlighted such as moisture content and the sum of temperatures during the growing season, frost-free period, etc. Basic soil tillage technologies that minimize the impact of limiting factors on the yield are considered. A generalized block diagramme of the selection process of technologies and technical means for the crop cultivation is presented. Constraints are formed that affect the choice of agricultural technology such as soil and climatic conditions, phytosanitary conditions, crop rotation, availability of seeds and equipment, etc. Optimization criteria have been substantiated that allow to choose technologies and technical means, ensuring cost reduction, energy saving and labor saving while following the specified agrotechnical deadlines of technological operations. A mathematical model has been developed with optimality criteria: consumption of fuels and lubricants, the number of machine operators and production cost. The model includes the following restrictions: the agroclimatic location of the farm, personnel potential, and fulfilment of a given amount of work. The model allows to evaluate agricultural technology and technical means according to the following parameters: the minimum amount of direct costs, the minimum consumption of fuel and lubricants and the necessary number of machine operators for the implementation of agricultural technology. This model will become the basis of the software, which will be used to test the results and data obtained on a specific farm. The use of this software will increase the efficiency of agricultural production by making informed management decisions for agricultural producers in the selection and implementation of technologies.

Résumé La traduction du roman gothique anglais en France au tournant du XVIIIe siècle — Au cours de la dernière décennie du XVIIIe siècle et au début du siècle suivant, le roman gothique anglais fait l'objet d'une entreprise de traduction systématique en France. Cet article entend montrer l'ampleur de cette vague d'importations, s'interroger sur le traitement des oeuvres originales et inviter à réfléchir sur les effets d'une diffusion aussi massive dans la culture d'accueil. Dans une première partie, nous démontrons, chiffres à l'appui, l'existence du phénomène, en centrant la recherche sur un corpus restreint de titres. Après un commentaire du diagramme obtenu, quelques éléments d'explication sont avancés. Puis nous envisageons la qualité des adaptations françaises, ce qui nous conduit à nous interroger sur le rôle et le statut des traducteurs à cette époque. Nous constatons que le souci de plaire aux lecteurs prévaut sur l'exigence de fidélité aux textes. Enfin, nous tentons d'évaluer les conséquences de cette vogue sur la production des auteurs nationaux. Un premier effet pervers se manifeste par la multiplication des fausses traductions et des imitations: il est possible d'observer les différentes formes de manipulation du texte source. Tout cela perturbe les données du marché de la librairie et aboutit à une prolifération d'ouvrages de médiocre qualité. Cependant, il est indéniable que l'école de la Terreur a exercé, à long terme, une féconde influence sur les romanciers français du XIXe siècle, grâce à la médiation de ces traductions d'inégale qualité.

The article uses the unified UML modeling language to visualize production elements. To show some of the advantages of the proposed approach, the main components of the production system are defined: technological machines, operators, materials, products and the production process. A class diagram is used to represent the components. Defined attributes and methods of each class: attributes and methods to each class that define its properties and behavior. The Machine class can have attributes such as machine ID and Destination, and methods such as start() and stop(). Relationships between classes are established: association, aggregation, and composition to represent relationships between classes. The Production Process class can have an aggregation relationship with the Machine class, indicating that the production process consists of multiple machines. This work contains UML diagrams and description tables that make it possible to structure the activity of the technological process in production. The technological process of manufacturing products is shown, which is presented in detail on the state diagram.

La vallée de Boghol est située dans la région d’Agadez au nord du Niger. Elle constitue un bassin de production où l’agriculture irriguée est la principale activité. Cette dernière occupe la grande majorité de la population et se pratique durant toute l’année avec l’eau souterraine comme l’unique source d’eau d’irrigation. Malgré la méconnaissance de la qualité de ces eaux, l’irrigation connait une intensification susceptible d’impacter la nappe phréatique. L’objectif de ce travail est de contribuer à caractériser les eaux de ladite vallée. L’approche méthodologique s’est basée sur le prélèvement des échantillons d’eau au niveau des puits maraichers sur la base d’un transect permettant de couvrir toute la vallée. Ces eaux ont fait l’objet de mesures physiques sur le terrain et d’analyses chimiques au laboratoire par titrimétrie, puis photométrie. Outre l’analyse en composante principale, le traitement des résultats a été fait en utilisant le diagramme de Piper et celui de Schoeller-Berkaloff. Aussi, les méthodes du taux d’absorption du sodium (SAR), Wilcox et de carbonate de sodium résiduel (RSC) ont été utilisées. Les résultats de l’étude montrent que les eaux sont de bonne qualité organoleptique. Quant au pH, les valeurs sont presque neutres dans tous les ouvrages. La conductivité électrique varie de 220,50 à 606,3 μs/cm et présente le plus grand nombre de corrélation avec les autres paramètres physicochimiques. Tous les échantillons ont un faciès chimique bicarbonaté calcique et ont une bonne aptitude à l’irrigation. Cependant, il est constaté une augmentation spatiotemporelle du taux de minéralisation et celui du nitrate. D’où la nécessité de préserver cette qualité en adoptant des bonnes pratiques d’irrigation.
 The Boghol Valley is located in the Agadez region in northern Niger. It is a production basin where irrigated agriculture is the main activity. The latter occupies the vast majority of the population and is practiced all the year with groundwater as the only source of irrigation water. Despite the lack of knowledge about the quality of these waters, irrigation is being intensified and is likely to impact the water table. The objective of this work is to help characterize the waters of this valley. The methodological approach was based on the collection of water samples from vegetable wells/market garden wells based on a transect covering the whole valley. These waters were the subject of physical measurements in the field and chemical analyses in the laboratory by titrimetry, then photometry. In addition to the main component analysis, the results were processed using the Piper and Schoeller-Berkaloff diagrams. Also, the methods of sodium absorption rate (SAR), Wilcox, and residual sodium carbonate (RSC) were used. The results of the study show that the water is of good organoleptic quality. As for pH, the values are almost neutral in all works. Electrical conductivity ranges from 220.50 to 606.3 μs/cm and is

During the last four decades Data Envelopment Analysis (DEA) has attracted considerable attention in the OR community. Using DEA, the efficiency frontier is constructed based on assumptions concerning the production possibility set rather than a priori defining a functional relationship between inputs and outputs. In this contribution, we propose an algorithm to visualize the efficiency surface in a 3D diagram and to extract isoquants from the efficient hull based on different RTS assumptions which might be particularly helpful for presentation purposes. In doing so, we extend the existing literature which has concentrated on the visualization of production frontiers in 2D diagrams to the visualization of efficient rather than fully efficient hulls in 3D diagrams. Displaying a fully efficient hull, however, does not reflect all properties of the production possibility set as weakly efficient frontier segments are missing.

Denim fabric sort number 78032 is one type of fabric in the last 4 years almost every month produced by PT Apac Inti Corpora. In the continuity of denim fabric production process, there are data defects (non-conformity) that causes the quality of denim fabric decreases. To maintain the consistency of the quality of products produced in accordance with the specified specifications, it is necessary to control the quality of the production process that has been running for this. Multivariate control charts attributes used are multivariate control charts np using the number of samples and the proportion of disability data with correlation between variables while the chi-square distance control charts use squared distances with uncorrelated data between variables. The results showed that in the multivariate control chart np there were 2 out-of-control observations in the phase II data using control limits from phase I data already controlled by the value of BKA of 636321.4. While in the chi-square distance control chart showed all observations are in in-control condition with BKA value of 0.06536. Controlled production process obtained multivariate process capability value for multivariate control np diagram of 0.625142 <1 which means the process is not capable, while the value of process capability in the chi-square distance control chart is 1.1329> 1 which means the process is capable.

Absolute statistical data are very often expressed by a diagram in thematic maps. The ArcGIS 9 software from ESRI is commonly used for the production of cartographic output, but there are only a few possibilities for how to express data by diagram maps. A program extension called “Diagram map creator” was developed at the Department of Geoinformatics, Palacký University in 2010. This extension serves as a supplement for the automatic generation of various diagram maps. The program code, user interface and the possibilities of and the use of the “Diagram map creator” extension are presented in this article. Some examples of thematic maps are also shown.

Cette thèse s’inscrit dans le cadre du développement de cibles d’irradiation faiblement enrichi en ²³⁵U pour la production du ⁹⁹Mo, radionucléide père du ⁹⁹mTc employé en imagerie médicale. La cible d’irradiation est une plaque fine en aluminium, dont l’âme fissile est constituée d’une dispersion de particules uranifères dans une matrice d’aluminium. Nos travaux plus spécifiquement ont mené à proposer une âme fissile alternative à celle actuellement employée. Pour évaluer les effets de l’affinité chimique, une approche thermodynamique par détermination des relations de phases a été considérée pour cinq systèmes ternaires de références. Les travaux expérimentaux ont conduit à la détermination de sections isothermes pour les systèmes U-Al-X avec X= Ti, Zr, Nb, Ga et Ge, pour deux températures, une basse et une haute températures représentatives des interactions avec l’uranium dans sa forme allotropique orthorhombique (αU) et cubique (gU) respectivement. Les systèmes ternaires U‑Nb-Al et U-Al-Ga, ont fait l’objet d’une optimisation thermodynamique par méthode CALPHAD. Des caractérisations supplémentaires ont été menées sur les phases intermédiaires afin de déterminer leurs propriétés physico-chimiques. Ces examens ont concerné leurs propriétés thermodynamiques (réaction de formation et température et pour certaines enthalpie de formation), structurales et également l’investigation de leurs propriétés électroniques. Cette thèse s’est également intéressée à l’étude des germaniures d’uranium ternaires, U₃TGe₅, en particulier à la recherche de nouvelles phases isotypes et à la caractérisation de leurs propriétés électroniques. Neuf nouveaux composés ont été identifiés pour les métaux T = V, Cr, Zr, Mn, Nb, Mo, Hf, Ta et W avec un arrangement structural similaire à l’antitype Hf₅CuSn₃ et des comportements variés et complexes, tels des fluctuations de spin, de l’ordre antiferromagnétique et ferromagnétique, illustrant le rôle prépondérant du métal de transition dans ces effets électroniques<br>This thesis is in the framework of the development of low ²³⁵U enriched irradiation targets for the ⁹⁹Mo production, the mother isotope of ⁹⁹mTc, which is the main radioactive tracers used in nuclear medical imaging. The aim of this work is to identify a new material with a higher uranium density. To fulfil this objective, the determination of the phase relations has been considered for five ternary systems. The experimental work was the determination of the isothermal sections of the U-Al-X with X = Ti, Zr, Nb, Ga and Ge for two temperatures, for representative interactions with U in its orthorhombic form (αU) and cubic form (gU) respectively. The U-Nb-Al and U-Al-Ga ternary system were thermodynamically assessed by CALPHAD assessment. Subsequent characterizations have been carried out on the intermediate phases to determine their physical properties. These studies comprise their thermodynamic features (reaction of formation, including the reaction temperature and for some their enthalpy of formation), structural properties (by means of X-ray and electron diffractions) and their electronic properties, magnetic, and transport (electrical and thermal). This Ph-D thesis was extended to the study of ternary uranium germanides with the general formula U₃TGe₅ by seeking for new isostructural compounds and to investigate their electronic properties. Nine new compounds have been identified with the transition metal, T = V, Cr, Mn, Zr, Nb, Mo, Hf, Ta and W with an anti-Hf₅CuSn₃ structural type and various and complex behaviors, such as spin fluctuators, antiferromagnetic and ferromagnetic orders, emphasizing the predominant influence of the transition metal in these electronic phenomena

La malnutrition est une menace importante pour la santé humaine. Au Togo, la purée de niébé appelée localement « Adowè » et potentiellement riche en nutriments peut servir à lutter contre la malnutrition déficitaire. Cependant, force est de constater que la sphère de production et de consommation de cette purée ne cesse de se réduire au fil des ans. Les présents travaux de thèse sur « Adowè » ont donc pour objectifs : (i) de contribuer à la lutte contre la carence nutritionnelle protéino-calorique par l’exploitation des agroressources endogènes comme le niébé (protéines végétales), (ii) de préserver l’environnement face à un rythme croissant de la consommation des protéines animales dans le monde. De ce fait, la valorisation et la réhabilitation de « Adowè » nous ont conduit à l’étude de sa production à l’échelle industrielle. La compression mécanique des graines de niébé pour déterminer leurs états cuits et les propriétés rhéologiques de la purée « Adowè » ont également été examinées dans cette thèse. Les résultats obtenus ont montré que l’état cuit des graines peut être évalué par des grandeurs physiques. L’énergie d’activation de cuisson des graines a également été déterminée. Ainsi, ces paramètres permettront de contrôler énergétiquement le procédé de cuisson des graines. La caractérisation rhéologique de la purée a montré un fluide à seuil pour les purées dont la concentration massique se situe entre 12 et 20%. Au-delà de 20% de concentration, la méthode de mesure de la viscosité par rotation pour la caractérisation rhéologique de « Adowè » n’est pas applicable. De ce fait, la méthode d’extrusion inverse a été exploitée pour quantifier la viscosité de « Adowè » à 31 ± 2 % (masse/masse). Ces résultats sont très intéressants et pourront être utiles pour un passage de la production artisanale à une production industrielle de « Adowè »<br>Malnutrition is a significant threat to human health. In Togo, cowpea puree, known locally as "Adowè", is potentially rich in nutrients and can be used to fight against malnutrition. However, this puree has seen reduced production and consumption over time. The aim of this thesis is to contribute to the fight against protein-calorie malnutrition through the use of endogenous agricultural resources, such as cowpea seeds (plant proteins). In a world where animal proteins consumption is on the rise, this work also helps to contribute towards environmental preservation. Therefore, promoting the development and rehabilitation of "Adowè" requires us to study its production on an industrial scale. Experiments were carried out to determine the cooked state of the cowpea seeds by mechanical compression. The rheological properties of the "Adowè" puree were also determined. The results obtained show that the cooked state of the seeds could be assessed by physical quantities. The activation energy for the cooking of theseeds has also been determined. These parameters will therefore be the basis for the energetic control of the seed cooking process. Finally, the rheological characterisation of the puree was carried out using two methods. For purees with mass concentrations between 12 and 20%, "Adowè" is a yield stress fluid. Beyond 20% concentration, oscillatory and steady shear viscosity measurements of the puree become intractable. Therefore, back extrusion method was used to quantify the viscosity of the puree at 31±2% (mass/mass). These results are useful fortransitioning from artisanal to industrial production of "Adowè"

One part of this project consisted in determining the gas hydrate equilibrium conditions involving these promoters and the different gas phases (CO2, CH4 and simulated biogas). Differential scanning calorimetry (DSC) methods were applied to measure the phase transition temperatures. Therefore, new phase equilibrium data were determined for the promoter/gas hydrate systems. In the second part of the project, we carried out quantitative measurements in an instrumented reactor in order to evaluate the GSFH process for upgrading biogas. Each promoter was evaluated in kinetics and thermodynamics aspects, such as crystal growth rate, amount of gas trapped into the hydrate phase, and selectivity. The optimization of the hydrate formation / dissociation cycle showed excellent results in terms of kinetics improvement

This thesis explores techniques for the automated production of schematic diagrams, in particular those in the style of metro maps. Metro map style schematics are used across the world, typically to depict public transport networks, and therefore benefit from an innate level of user familiarity not found with most other data visualisation styles. Currently, this style of schematic is used infrequently due to the difficulties involved with creating an effective layout – there are no software tools to aid with the positioning of nodes and other features, resulting in schematics being produced by hand at great expense of time and effort. Automated schematic layout has been an active area of research for the past decade, and part of our work extends upon an effective current technique – multi-criteria hill climbing. We have implemented additional layout criteria and clustering techniques, as well as performance optimisations to improve the final results. Additionally, we ran a series of layouts whilst varying algorithm parameters in an attempt to identify patterns specific to map characteristics. This layout algorithm has been implemented into a custom-written piece of software running on the Android operating system. The software is targeted at tablet devices, using their touch-sensitive screens with a gesture recognition system to allow users to construct complex schematics using sequences of simple gestures. Following on from this, we present our work on a modified force-directed layout method capable of producing fast, high-quality, angular schematic layouts. Our method produces superior results to the previous octilinear force-directed layout method, and is capable of producing results comparable to many of the much slower current approaches. Using our force-directed layout method we then implemented a novel mental map preservation technique which aims to preserve node proximity relations during optimisation; we believe this approach provides a number of benefits over the the more common method of preserving absolute node positions. Finally, we performed a user study on our method to test the effect of varying levels of mental map preservation on diagram comprehension.

Nous présentons une étude phénoménologique basée sur un Lagrangien effectif, via les diagrammes de Feynman au premier ordre, pour décrire les réactions de photoproduction d'étrangeté sur le proton : γp → K+ Λ, K+ Σ⁰, K⁰Σ⁺, K+ Λ* (1405) ; sur le neutron : γn→ K+ Σ⁻ ; et sur le deuton d(γ, K⁺)X dans l'approximation de l'impulsion relativiste, ainsi que l'ensemble de ces processus avec un faisceau d'électrons. Notre formalisme incorpore également les réactions de capture radiative K⁻p → γΛ, γΣ⁰. Les paramètres libres des modèles sont déterminés par des ajustements sur l'ensemble des résultats expérimentaux disponibles pour les observables de ces réactions, du seuil à Eγ [exposant lab] ≈ 2. 5 GeV. Le formalisme des effets hors-couche inhérent au traitement des résonances nucléoniques et hypéroniques de spin 3/2, déjà développé pour la production de K+ Λ est généralisé à l'ensemble des réactions ci-dessus. Une étude approfondie des facteurs de forme électromagnétique des hadrons étranges via les réactions d'électroproduction est effectuée. Nous avons également introduit des facteurs de forme aux vertex hadroniques dans la description des réactions de photo- et électro-production, tout en préservant l'invariance de jauge. Le formalisme ainsi développé est utilisé dans la recherche de modèles pour la production électromagnétique d'étrangeté associée sur le nucléon et le deuton. Après une étude détaillée des ingrédients des mécanismes des réactions, nous présentons des modèles relativement simples permettant de décrire les données disponibles. Enfin, nous mettons en exergue la spécificité de chaque observable et proposons des perspectives pour des études expérimentales et théorique en la matière.

AbstractEvery person sometimes chooses different foods, based in part on preferences developed over time in their family, cultural and community context. Similarly, each farmer has their own way of helping crops and livestock grow, and every food producer transforms ingredients into final products in a unique manner. Individual actions by millions of consumers and producers underpin the food systems we observe. In this chapter, we use analytical diagrams with indifference curves and budget lines to explain food consumption choices and predict how food consumption might change in response to different prices, incomes and preferences. Then we explain production choices using a set of three different analytical diagrams, explaining what is produced using a production possibilities frontier and its revenue line, as well as an input response curve and its profit line, and explaining how each thing is produced using an isoquant and its cost line. Together, these diagrams reveal how changes in prices, natural resources and technology affect agriculture and food production. Finally, we show how consumption and production together explain the choices of family farmers, allowing us to describe a variety of current events in the agricultural sector using economics principles.

AbstractThermal errors remain the dominant sources of positioning inaccuracies in machine tools. Various methods of reducing them have already been developed, ranging from cooling and air conditioning strategies, thermally optimized machine tool designs and component optimization to accurate model based thermal error estimation methods used for control-integrated compensation. Some reasons for the limited success of these strategies are the general complexity of the thermo-elastic and thermodynamic processes involved and the fact that many models’ effectiveness is dependent on the machine tool type, workpiece, climatic conditions, tool, CAM strategy, condition of the machine tool and other factors. Depending on these circumstances, all model-based estimation and compensation methods have specific strengths and weaknesses, which make them more suitable in some aspects and less suitable in others. A possible way of circumventing this is via the combination of several methods to hybrid compensation. The goal of this investigation is to develop an effective hybrid compensation strategy for the 5-axis machine tool DMU 80 eVo by combining measurement-based compensation using integrated deformation sensors (IDS) with characteristic diagram based compensation. The former is used for the compensation of thermal errors in the vertical column containing the larger assemblies of the x, y, and z-axis and the latter is used for the table, which contains two rotational axes.The IDS placement has been determined through expert knowledge and compared to placement, which minimizes the variance of the TCP displacement. The hybrid compensation is tested on the DMU 80 eVo.

In the current work, a new error evaluation methodology is introduced based on error analysis in ship production with reverse engineering data. The aim is to determine the errors and prevent or reduce the occurrence in other projects. First step is to compose a database of the errors; then, group the similar errors and calculate the Error Priority Number (EPN) by the evaluation of the predetermined criteria. The radar diagrams, which are suitable for representing a number of parameters having the same variables, were used to present the error groups in a simple way. The error groups were created on the diagram with the scores taken from the specific criteria. With the aid of the radar diagram, valuable information is given by presenting similarities and dissimilarities of these errors with other error groups. After examining the radar diagrams and evaluating the results, the cause and effect diagrams were prepared for these error groups from the field experts. Thus, the methodology should be customized for the shipyard to ensure maximum efficiency.

Esta investigación aborda la problemática que actualmente plantea la planificación de lo urbano, relacionando
 este hecho, a nivel teórico, con la dificultad que entraña su propia representación. Dicha consideración nos
 lleva a prestar especial atención a los diagramas urbanos, entendiéndolos como mínima expresión gráfica de
 los ensamblajes socio-espaciales.
 Se analizan por ello diversos ejemplos paradigmáticos de este tipo de diagramas, estudiando el modo en que
 se combinan sus componentes básicos, poniéndolos en relación con el sentido con que se produjeron. A su
 vez, se pretende verificar en qué medida son el resultado de una tradición, y en cual han tenido un valor
 productivo (capacidad de generar diferencia).
 Se pretende con ello poner de manifiesto la complejidad y la no linealidad de los procesos de producción del
 espacio y, principalmente, subrayar la profunda influencia que en ellos juegan los valores culturales
 subyacentes. This research addresses the contemporary problem of planning the urban realm. For that purpose, it makes a
 theoretical approach about the difficulty of the representation of this phenomenon. It make us to focus in the
 minimum graphic expression of the socio-spatial assemblies: The urban diagrams.
 It will analyze some paradigmatic examples of this kind of diagrams, studying the way in which are combined
 theirs basic components, relating them with the values of the era and place where were produced. At the same
 time, the intention is to verify if they are the results of a tradition and something productive (able to create
 difference.
 At the end, we want to show the complexity and no-linearity of the processes of production of space and,
 mainly, highlight the deep influence of the underlying cultural values.

Diagrams used in design processes exclusively serve the resultant object of the work, and we often understand diagrams in terms of how they might serve the discipline within which they are intended to function. In this sense, diagrams are a means to an objective that is distant from, and external to, the designer. However, diagramming intended for reinforcing cognitive capacities required for abstract thinking, comprehension of increasingly complex conditions surrounding a problem, and strategic planning reorients the intention back towards the student-architect. At the same time, this focus on process within the architect suggests a stratum of architectural definition that is innately internal, manifested within the conceptual, the virtual, and through the imagination. What occurs if we reverse our focus from the diagram’s service to architecture to the diagram’s service to the architect? How does the diagrammatic process serve the architect? How does diagramming develop understanding of architecture by shaping cognitive utility towards its concepts? How can we fold this into pedagogy and knowledge production to establish methods towards expansion of architectural cognition?

Abstract. For the analysis of the quality of metallurgical products, it is important to use techniques that identify the internal and external unconformity of the product without destroying it. These techniques are non-destructive testing (NDT). Although these techniques identify the unconformity of the product, they do not indicate the source of their creation. The purpose of the study was to develop a hybrid method to make decisions about the causes of product incompatibility. This hybrid method was created as a combination of NDT and quality management techniques, i.e.: 5W2H method, Ishikawa diagram, 5Why method. The subject of the study was an unconformity detected in the tube made of the magnesium alloy AMS 4439. Research was carried out using the FPI method. In the analyzed case, its application allowed the detection of a linear indication in the product. To identify the root of the linear indication, the 5W2H method, the Ishikawa diagram, and the 5Why method were used sequentially. The main causes were bad casting and pollution. The root cause was defective supplier material. Integration of the FPI method, the 5W2H method, the Ishikawa diagram, and the 5Why method in the performance of a comprehensive qualitative analyze of products, after which it is possible to identify the unconformity and the root of its occurrence. The integration of FPI and quality management techniques can be practiced to analyze the quality of products (including metallurgical products) in manufacturing and service enterprises.

Bifacial vertically mounted solar panels represent a technical solution that converts solar energy into electricity in a way that overcomes certain disadvantages of conventional monofacial south-facing solar panels, primarily in terms of daily and annual production diagrams, as well as the problem of soiling of panel surfaces. In this paper, the production of a monofacial south-oriented photovoltaic power plant and a bifacial photovoltaic power plant with surfaces oriented east-west were analysed, with reference to the north-south orientation. Also, their correlation with the consumption diagram and the electricity price diagram on the market was analysed. The analysis will include the impact of snowfall, temperature and soiling of the module. The effect of land occupation and the possibility of using it for agricultural purposes will also be considered. Analyses will be performed at a real location using real data on insolation and parameters of photovoltaic modules.

The article describes the stages of modeling an intelligent system for evaluating multilevel test tasks based on fuzzy logic in the MATLAB application package, namely the Fuzzy Logic Toolbox. The analysis of existing approaches to fuzzy assessment of test methods, their advantages and disadvantages is given. The considered methods for assessing students are presented in the general case by two methods: using fuzzy sets and corresponding membership functions; fuzzy estimation method and generalized fuzzy estimation method. In the present work, the Sugeno production model is used as the closest to the natural language. This closeness allows for closer interaction with a subject area expert and build well-understood, easily interpreted inference systems. The structure of a fuzzy system, functions and mechanisms of model building are described. The system is presented in the form of a block diagram of fuzzy logical nodes and consists of four input variables, corresponding to the levels of knowledge assimilation and one initial one. The surface of the response of a fuzzy system reflects the dependence of the final grade on the level of difficulty of the task and the degree of correctness of the task. The structure and functions of the fuzzy system are indicated. The modeled in this way intelligent system for assessing multilevel test tasks based on fuzzy logic makes it possible to take into account the fuzzy characteristics of the test: the level of difficulty of the task, which can be assessed as “easy”, “average", “above average”, “difficult”; the degree of correctness of the task, which can be assessed as “correct”, “partially correct”, “rather correct”, “incorrect”; time allotted for the execution of a test task or test, which can be assessed as “short”, “medium”, “long”, “very long”; the percentage of correctly completed tasks, which can be assessed as “small”, “medium”, “large”, “very large”; the final mark for the test, which can be assessed as “poor”, “satisfactory”, “good”, “excellent”, which are included in the assessment. This approach ensures the maximum consideration of answers to questions of all levels of complexity by formulating a base of inference rules and selection of weighting coefficients when deriving the final estimate. The robustness of the system is achieved by using Gaussian membership functions. The testing of the controller on the test sample brings the functional suitability of the developed model.
