Abstract:
Since the inception of recorded music there has been a need for standards and reliability across sound formats and listening environments. The role of the audio mastering engineer is prestigious and akin to a craft expert combining scientific knowledge, musical learning, manual precision and skill, and an awareness of cultural fashions and creative labour. With the advent of algorithms, big data and machine learning, loosely termed artificial intelligence in this creative sector, there is now the possibility of automating human audio mastering processes and radically disrupting mastering careers. The emergence of dedicated products and services in artificial intelligence-driven audio mastering poses profound questions for the future of the music industry, already having faced significant challenges due to the digitalization of music over the past decades. The research reports on qualitative and ethnographic inquiry with audio mastering engineers on the automation of their expertise and the potential for artificial intelligence to augment or replace aspects of their workflows. Investigating audio mastering engineers' awareness of artificial intelligence, the research probes the importance of criticality in their labour. The research identifies intuitive performance and critical listening as areas where human ingenuity and communication pose problems for simulation. Affective labour disrupts speculation of algorithmic domination by highlighting the pragmatic strategies available for humans to adapt and augment digital technologies.

Abstract:
This article proposes a contextualist approach to machine learning and aesthetics, using LANDR, an online platform that offers automated music mastering and that trumpets its use of supervised machine learning, branded as artificial intelligence (AI). Increasingly, machine learning will become an integral part of the processing of sounds and images, shaping the way our culture sounds, looks, and feels. Yet we cannot know exactly how much of a role or what role machine learning plays in LANDR. To parochialize the machine learning part of what LANDR does, this study spirals in from bigger contexts to smaller ones: LANDR’s place between the new media industry and the mastering industry; the music scene in their home city, Montreal, Quebec; LANDR use by DIY musicians and independent engineers; and, finally, the LANDR interface and the sound it produces in use. While LANDR claims to automate the work of mastering engineers, it appears to expand and morph the definition of mastering itself: it devalues people’s aesthetic labor as it establishes higher standards for recordings online. And unlike many other new media firms, LANDR’s connection to its local music scene has been essential to its development, growth, and authority, even as they have since moved on from that scene, and even as the relationship was never fully reciprocal.

Abstract:
Successful training of prospective communications engineers at a technical university requires strengthening the mathematical component of the developing professional competencies. The readiness to master such competencies begins long before entering a university and requires Math teachers at school and university to pay attention to all aspects of the problem, namely: initial mathematical training is the main foundation for the formation of a communications engineer, the level of school mathematical education should meet the requirements of the profession, only provided that the necessary level of basic mathematical training is formed, one can be sure of the quality of mastering professional competencies, first in the process of studying at the university, and then directly while performing work duties. The attention of the authors of the paper is focused on the joint actions of school and university teachers in this direction. In addition, the teaching of mathematics at the university also needs to explicitly highlight the existing connections in the mathematical content and methods of mastering it through the conscious application of various methodological techniques, in other words, the professional orientation of the mathematical training of communications engineers in the process of studying all sections of mathematics at the university is necessary. The paper proposes specific steps to solve this problem on the example of teaching mathematical courses to undergraduate students majoring in 11.03.02 Infocommunication technologies and communication systems at Povolzhsky State University of Telecommunications and Informatics.

Abstract:
The loudness wars have been a frequently debated topic in the audio industry. Earlier research has been done on the technical and perceptual effects of loudness and so called hyper- compression but little research has been done to investigate the opinions of the mastering engineers, those who are applying the processing. This research is set out to understand the practise and goals of mastering engineers relating to loudness and hyper-compression, trying to broaden the subject with the viewpoint of those responsible for applying this loudness processing. The goal was to find commonalities amongst the engineers regarding the topic and to investigate the reasoning of the engineers. The study is based of five semi-structured interviews with professional mastering engineers. The interviews were conducted over Skype and the analysis was of a grounded method, originating from three main categories; commercial, technical and aesthetic, and subcategories were generated by the interviews. The research showed that the use of loudness and hyper-compression is multifaceted, with different goals depending on who the user is. There seems to be a strong connection between the loudness processing and genre, that genre often dictates how the processing is used. The research also found that there is a common opinion towards a standardisation of loudness normalisation in streaming services.

Abstract:
Throughout the history of the recording industry, the creative practices of mixing and mastering engineers were viewed simultaneously as a dark art and a highly specialized skill set requiring years of training in critical listening. In the 2010s, the implementation of AI algorithms and deep learning techniques in mixing and mastering plug-ins made these techniques available to casual users with a single button click. This chapter surveys the emergence of automation in the creative workflows of music producers, from AI drum machines and composition algorithms to the mixing and mastering “assistants” available in iZotope’s suite of plug-ins. How have automated tools for music composition, postproduction, and distribution affected divisions of labor in the recording industry? Further, how might the ocular-centric design of software plug-ins shape the nature of musical listening, especially amid twenty-first-century debates about automation and digital surveillance?

Abstract:
In the given article is examined the essence of the notion of «сommunicative competence» elaborated by Ukrainian and foreign scientists. In recent decades, the concept of “competence” has become increasingly apparent at the general didactic and general pedagogical level. Increased attention to this concept was also due to the recommendations of the Council of Europe in questions on the renewal of education. Considering the different approaches to the definition of “competence”, we conclude in the article that competence is understood as the knowledge that a person must master in the learning process, the result of mastering the content of education, which should be manifested in future professional activities. According to the educational and qualification characteristics of an agrarian specialist, students must have not only general technical and special skills, but also be able to find a common language with colleagues, perform a number of management functions. The purpose of the article is to analyze the concept of “communicative competence” and determine the structure of communicative competence of future agrarian engineers. Also the article examines the pedagogical conditions of formation of the communicative competence of future agrarian specialists. The formation of the communicative competence requires the need to substantiate the pedagogical conditions under which the formation will take place in the most effective way. It is shown that the process of forming of the communicative competence of future agrarian specialists is impossible without the creation and implementation of pedagogical conditions, on which the efficiency of the learning process depends and that affects the quality of the training. It has been proved that this process will be more successful, while using such pedagogical conditions as the use of a personality-oriented approach in teaching, providing of a contextual approach and the subject position of students in the process of professional communication training; the use of training exercises and games aimed at increasing the communication activity of students.

Abstract:
This chapter aims to master web mining and Information Retrieval (IR) in the digital age, thus describing the overviews of web mining and web usage mining; the significance of web mining in the digital age; the overview of IR; the concept of Collaborative Information Retrieval (CIR); the evaluation of IR systems; and the significance of IR in the digital age. Web mining can contribute to the increase in profits by selling more products and by minimizing costs. Web mining is the application of data mining techniques to discover the interesting patterns from web data in order to better serve the needs of web-based multifaceted applications. Mining web data can improve the personalization, create the selling opportunities, and lead to more profitable relationships with customers in global business. Web mining techniques can be applied with the effective analysis of the clearly understood business needs and requirements. Web mining builds the detailed customer profiles based on the transactional data. Web mining is used to create the personalized search engines which can recognize the individuals' search queries by analyzing and profiling the web user's search behavior. IR is the process of obtaining relevant information from a collection of informational resources. IR has considerably changed with the expansion of the Internet and the advent of modern and inexpensive graphical user interfaces and mass storage devices. The effective IR system, including an active indexing system, not only decreases the chances that information will be misfiled but also expedites the retrieval of information. Regarding IR utilization, the resulting time-saving benefit increases office efficiency and productivity while decreasing stress and anxiety. Most IR systems provide the advanced searching capabilities that allow users to create the sophisticated queries. The chapter argues that applying web mining and IR has the potential to enhance organizational performance and reach strategic goals in the digital age.

Abstract:
Choosing cutting tools and end-milling conditions depends on expert engineers’ knowledge and experience, and often a lengthy process of trial and error is required before they obtain appropriate cutting conditions. We have previously proposed data-mining methods to make decisions about end-milling conditions on the basis of catalog data. We cut hardened die steel JIS SKD61 under three kinds of end-milling conditions: catalog recommended conditions, conditions derived from data-mining (mined conditions), and expert engineer conditions. We used LCA to evaluate quantitatively the environmental impact resulting from these conditions. We designed an index model of the environmental burden in the technical mastering process under the three condition. The results show that unskilled engineers could decrease the cumulative environmental burden by working under the mined condition in the initial stage. Recommending the use of the mined condition in the initial stage is therefore considered best.

Abstract:
Technical Innovation covers the process of creating a new successful competitive product from invention to production and market introduction within a practical company related context. Typically education for this kind of complicated, open ended work requires mastering a wide range of knowledge-areas and a lot of hands-on training practice in projects and workshops. The combination of depth and width is symbolized by the “T-shape”. Well-known learning theories give a good rationale of the teaching approaches that were developed over the years and a confirmation of this approach, including the important role of the experienced tutor, is found in the study of excellent companies. Work of a “T-shaped” engineer in the technical innovation process bears many similarities to the ideal transformation process of a company, like Collins describes in his “Good to Great”. The processes have a very comparable open-ended character, a focus for essence and simple, elegant solutions, opportunities and inventions. Success seems to rely more on the right people and a concentrated shared-goal driven cooperation (“flow”), than on the right methods of work. Collins’ observations and conclusions, applied to the domain of engineering design education helps understanding the earlier reported 15 years success of the International Product Design Engineering (IPDE) course of the Hanze University Groningen, with its combination of lecturing, projects and workshops, with a high reality content and direct supervision. The IPDE-related “Open Dynamic Design” (ODD) project and the educational experiments showed similar observations. Essential is the committed experienced participation in real innovation projects and intensive workshops, lead by very experienced T-shaped supervisors/“masters”, having deep knowledge over a good part of technologies, entrepreneurial and/or design related issues and good understanding of interrelationship and consequences in the other fields. They also should have a track record on the methodologies of product innovation and product development. Like the Collins level-5 leaders, they should be able to be both creative and analytical, give the students freedom and control them at the appropriate moments. They power the theoretical most effective learning “circle” with focused introductions and assignments, their direct, knowledgeable and adequate feedback, and quiet help during contemplation. Then the workshops are really fun and effective. The Loughborough and Glasgow Design engineering courses, the new master course at the Innovation Centre of the University of Technology of Compiegne (UTC) and the one at the Hanze Institute for Technology — an upgrade from IPDE — are built on these insights. To safeguard the continuation of this approach, a pool of experienced and potential (home and guest) T-experts is founded together by the small group of universities and their industrial partners, working jointly in the workshops, projects and modules, training the trainers while training the students - in T-design.

Abstract:
Abstract With energy shortages and increasing environmental problems, natural gas, as a clean energy, has the advantages of cheap price and large reserves and has become one of the main alternative fuels for marine diesel engines. For large bore natural gas engines, pre-chamber spark plug ignition can be used to increase engine efficiency. The engine mainly relies on the flame ejected from the pre-chamber to ignite the mixture of natural gas and air in the main combustion chamber. The ignition flame in the main combustion chamber is the main factor affecting the combustion process. Although the pre-chamber natural gas engines have been extensively studied, the characteristics of combustion in the pre-chamber and the development of ignition flame in the main combustion chamber have not been fully understood. In this study, a two-zone phenomenological combustion model of pre-chamber spark-ignition natural gas engines is established based on the exchange of mass and energy of the gas flow process in the pre-chamber and the main combustion chamber. The basic characteristics of the developed model are: a spherical flame surface is used to describe the combustion state in the pre-chamber, and according to the turbulent jet theory, the influence of turbulence on the state of the pilot flame is considered based on the Reynolds number. According to the phenomenological model, the time when the flame starts to be injected from the pre-chamber to the main combustion chamber, and the parameters such as the length of the pilot flame are analyzed. The model was verified by experimental data, and the results showed that the calculated values were in good agreement with the experimental values. It provides an effective tool for mastering the law of flame development and supporting the optimization of combustion efficiency.

Abstract:
Downstream of the Somma-Vesuvius volcanic complex, the countryside records the flourishing of communities based on agricultural economies that have been facilitated, since the early modern history, by the fertility of the land, the mildness of the climate and the favourable location with respect to the natural routes of communication. The adaptation and dialogue between this territory and man led to the realization of the so-called “masserie”, the articulated rural artefacts, mostly developed on a primitive compositional structure at court, in which residential and working functions seamlessly coexist. The paper discusses the sustainable and bioclimatic solutions for building and running evidence of this volcanic vernacular system, to inquire how the constructive knowledge, based on the awareness of the properties of local materials, has given solutions to various needs. Indeed, the peasants used the different characteristics of the various igneous rocks, exploited to their maximum performance capabilities, to realize rubble masonry, light vaults, outdoor flooring, and even fixed furniture. In the same functional and “green” resource use, the plan layout follows a distribution corresponding to the best use of the sun and its effects on environmental optimization, and the rainwater collection system connects multiple wells to the underground tank whose position, spatial conformation and materials are expertly engineered. The study finally deepens a case study (the masseria of the Duke of Salza) representing the application of local building tradition in terms of construction features and typological aspects, and the evidence of the history and vulnerabilities of the Vesuvian land. In addition, the specificities of the masseria sample allow mastering the functioning of the whole building organism and the quality of the finishes, which demonstrate how, in their formal simplicity, these vernacular “monuments” were soberly embellished and complexly designed.

Nowadays, environmental concerns are posing a great challenge to DI Diesel engines. Increasingly tightening emission limits require a higher attention on combustion efficiency. In this scenario, computational fluid-dynamics can prove its power guaranteeing a deeper understanding of mixture formation process and combustion. A high efficiency Diesel engine can be developed only mastering all the parameters that can affect the combustion and, therefore, NOx and soot emissions. In this work, the development of an engine in order to fulfill Tier 4i emission standard will be presented. Originally, the engine was a two-valve engine supplied with a DPF. Since no SCR aftertreatment is supplied, NOx emission target are achieved through external exhaust gas recirculation and retarding the start of injection. In order to fulfill Tier 4i emissions, the main concern is on soot emission and, thus, the combustion chamber has been re-designed, through CFD simulations, leading to a better interaction between the flow field, the fuel spray and the piston bowl geometry. Particularly, through intake phase simulations, performed with the CFD code Fire v2009 v3, different intake ducts, with different swirl ratio, have been simulated in order to provide a flow field as realistic as possible for the combustion simulations. Through combustion process simulations, performed with the CFD code Kiva, by varying different parameters the interaction between the swirl flow field, generated by the intake duct, the reverse squish motion, and motions aerodynamically generated by spray has been investigated leading to the definition of a new engine lay-out. The study shows how, given the need of retarded injection for limiting NOx emission, the decrease of swirl ratio, when combined with a proper piston bowl design, allows a significant decrease of soot emissions and the achievement of Tier 4i emission standard.

Abstract:
Cavity flows are essential components of many aeronautical and spatial engines. For example, in gas turbines a network of cavities is calibrated and managed to divert part of the main cold stream which is then re-injected in the hot regions of the engine to shield walls from the hot combustion products. For pumps, cavities are naturally present at the junction of fixed and rotating parts. In both contexts, mastering the flow stability in rotor/stator cavities is essential to avoid imposing too large flow variations which could lead to miss-tuned operating conditions in the engine and a drastic loss of performance or life-span. Although stability of these flows has been widely studied in the literature, a lack of clear understanding of the triggering mechanisms from stable to unstable flow solutions remains, especially in the context of industrial applications where Reynolds numbers are very high and difficult to handle. To cope with such complex geometry, fully unsteady flows, the so-called Large Eddy Simulation (LES) approach appears as a very promising method. However and for such high Reynolds number industrial applications, wall modeling still remains a necessity to alleviate the computational cost of LES. Understanding the impact of such a strong modeling hypothesis on the mean flow features and unsteady energetic content is hence mandatory and the objective of the present discussion. To do so, the present paper studies LES flow solutions in an enclosed rotor-stator configuration with a stationary shroud. These simulations are performed using a two-steps Taylor-Galerkin finite-element scheme coupled to a WALE subgrid scale model giving a better prediction of the eddy viscosity in zones of strong shear. This allows capturing the unsteady structures known to be present in the boundary layers. Two sets of statoric boundary conditions are investigated: the dynamics of the boundary layer is either resolved using a fine mesh grid or modeled using a classic boundary layer law of the wall. It is shown that the modeling of the stationary disc layer induces an underestimation of the flow velocity at low radii and loss of accuracy in the radial description of the boundary layer structures. Despite these differences, the most energetic structures are found to have the same azimuthal organization as in the wall resolved configuration as well as the same pulsation, which in turn produces a boundary layer with the same spectral content as in the wall resolved test case.

Abstract:
The article presents the implementation of future agricultural engineers’ training technology in the informational and educational environment. To train future agricultural engineers, it is advisable to form tutorials for the study of each discipline in the conditions of informational and educational environment. Such tutorials are an assistance in mastering both theoretical material and course navigation, where interactive electronic learning tools are presented to perform tasks in the informational and educational environment. Higher education applicants perform such tasks directly in the classroom with the help of gadgets or personal computers. The final grade is formed from the scores obtained in the classroom and the rating of higher education applicants while studying in the informational and educational environment. The outlined approach is able to help in the quality of learning content. The use of interactive audiovisual online tools allows to get acquainted with the theoretical, practical and experimental provisions clearly, it is important for the training of future agricultural engineers. At the end of the experiment, it can be argued that the developed technology increases the level of motivation and self-incentive to work in the informational and educational environment. The application of the presented technology provides an opportunity to combine the educational process in the classroom with learning in the informational and educational environment, forms analytical abilities and competencies in professional activity. The reliability of the obtained results was checked using the λ Kolmogorov-Smirnov criterion. It is determined that when using this technology in the educational process, the indicators in the experimental group increased, which displays the effectiveness of training bachelors in agricultural engineering in the conditions of informational and educational environment.

Abstract:
The article analyzes the main stages of software engineering (SE) development. Based on the analysis of materials from the first SE conferences (1968-1969), it was determined how the software crisis prompted scientists and practitioners to join forces to form an engineering approach to programming. Differences in professional training for SE are identified. The fundamental components of the training of future software engineers are highlighted. The evolution of approaches to the design, implementation, testing and documentation of software is considered. The system scientific, technological approaches and methods for the design and construction of computer programs are highlighted. Analysis of the historical stages of the development of SE showed that despite the universal recognition of the importance of using the mathematical apparatus of logic, automata theory and linguistics when developing software, it was created empirically without its use. The factor that led practitioners to turn to the mathematical foundations of an SE is the increasing complexity of software and the inability of empirical approaches to its development and management to cope with it. The training of software engineers highlighted the problem of the rapid obsolescence of the technological content of education, the solution of which lies in its fundamentalization through the identification of the basic foundations of the industry. It is determined that mastering the basics of computer science is the foundation of vocational training in SE.
