This article discusses the advantages of spatial audio, in general, followed by strategies for applying spatial components to composition. The discussion then looks ahead to questions that may be solved by future implementations of spatial software and hardware. Despite the fact that technical systems for spatial audio have been in use since the 1950s, spatial concepts have not been widely integrated into the compositional process. This is because they involve a complex interaction of several phenomena, all of which play a role in the construction and perception of music. This article presents an analysis of the advantages of spatial audio for perception and provides examples of the decomposition of sonic material with the help of spatial properties, as well as a discussion of limitations in spatial construction and perception. Archival strategies for spatial audio are also briefly discussed.

Composition Process

Несмотря на множество доступных мобильных приложений с различными формами реализации (например, компонент, услуга или приложение), потребности пользователя отличаются от одного к другому. Кроме того, мобильные устройства характеризуются разнородными программными и аппаратными конфигурациями. Таким образом, важной проблемой при разработке мобильных приложений является их развертывание на доступных разнородных устройствах. Для решения этих проблем необходим процесс композиции, позволяющий повторно использовать существующие разнородные объекты для разработки мобильных приложений в соответствии с требованиями пользователя, и чтобы поведение желаемых приложений можно было настраивать в соответствии с их различной контекстной информацией. В статье эта проблема решается на основе процесса создания мобильных приложений с учетом контекста на основе существующих гетерогенных программных объектов. Despite the many mobile applications available with different forms of implementation (for example, a component, service or application), the user's needs differ from one to another. In addition, mobile devices are characterized by heterogeneous software and hardware configurations. Thus, an important problem in the development of mobile applications is their deployment on available heterogeneous devices. To solve these problems, we need a composition process that allows us to reuse existing heterogeneous objects for developing mobile applications in accordance with the user's requirements, and so that the behavior of the desired applications can be customized according to their different contextual information. In the article, this problem is solved on the basis of the process of creating mobile applications taking into account the context on the basis of existing heterogeneous program objects.

The key task of society development is to ensure rational use of natural resources and related continuous monitoring of natural and technical systems state. Regarding the growing problems of ensuring operational control of critical infrastructure facilities, tasks of epidemiological and environmental protection, solving the issues of developing new information technologies that meet modern requirements for scientific and practical activities and implementing their software and hardware modules for supporting decision-making on the presence of qualitative anomalous changes in monitoring data aimed at ensuring information and metrological reliability of control systems, becomes critical for the life support of the population. An information technology and a software and hardware module for supporting decision-making on the presence of qualitative abnormal changes in sample data, which are predictors of significant changes in the internal state of monitored objects, natural-technical systems or control devices, are proposed. A method for choosing parametric criteria for the difference in monitoring data using numerical measures of Shannon information entropy and Kullback-Leibler divergence is presented. The use of the developed and demonstrated in practice methodology makes it possible to achieve an increase in the accuracy, convergence and reproducibility of measurements through the use of numerical statistical modeling to obtain a numerical estimate of confident recognition boundaries of a qualitative anomalous change in the shape and shift of the sample distribution of monitoring data, including small samples.

JAMES CERVETTO AND THE ORIGIN OF HAYDN'S D MAJOR CELLO CONCERTO

Apparent Evidence

ABSTRACTHaydn's D major cello concerto has traditionally been associated with Anton Kraft, a performer in Haydn's orchestra at Eszterháza during the 1780s. Before Haydn's autograph came to light in the 1950s, many authorities had accepted apparent evidence that Kraft was the concerto's composer. Even after the autograph's rediscovery, the seeming connection of the concerto with Kraft appeared so compelling that it was widely assumed he participated in the compositional process. This article demonstrates that Kraft's connection with the concerto was actually fabricated in the 1830s. Contemporary reports show that the concerto was in fact composed for the distinguished virtuoso James Cervetto, who performed it in London in 1784. Both the distinctive characteristics of the concerto, often regarded by commentators as indications of compositional weakness, and also its exceptional technical challenges are here interpreted as responses to Cervetto's singular musical temperament and exceptional proficiency, communicated to Haydn through the commission.

System Configurations

In this paper we describe a new approach and support tool for the modelling and analysis of socio-technical system configurations. This novel approach has been developed for use on systems composed of a wide variety of different components including social and organisational elements, in addition to the more traditional software and hardware aspects. Configuration models of such systems are lightweight and quick to construct and can help to promote understanding by the various stakeholders involved in system development, operation and evolution. These models also provide the data required for performing various useful forms of automated analysis. The results of such analysis can allow managers, administrators, developers and end users to investigate various efficiency, productivity and dependability attributes of the current configuration of a system. This can help support decisions about the evolution of a system by allowing the assessment of proposed changes such as the addition or removal of components, processes and structures. In this paper we utilise a real world case study in order to demonstrate and evaluate the utility of the described approach.

Widespread Interest

Since the 1950s the spatiality of sound has become a key concept in different fields of artistic practice, emerging as one of the most relevant subjects in the contemporary arts. Ideas related to sound and space have been used in different discourses and practices to refer to or to explore perceptually different facets of the spatiality of sound. In the field of fine art they have been associated with the emergence of sound art, while in music, they have been associated with spatial music. In spite of this widespread interest in sound and space, the uses of spatial concepts in relation to sound and music have been inconsistent, with different authors and practitioners referring to different aspects of the complex relationship between the two. In this article I suggest a typology with five categories to describe five meanings of space I identified in the recent literature of music and sound art: metaphor, acoustic space, sound spatialisation, reference and location. With this typology I expect to clarify the contemporary uses of space and spatial concepts in music and sound art.

Determining Factor

This chapter discusses the ways in which twentieth-century artists have engaged with the aesthetic dimensions of algorithms and machine autonomy. It extends the narrative on the history of machine art from the previous chapter, beyond the program of Hultén’s 1968 “Machine” exhibition. It explains how the dialogue between art and cybernetics has evolved from the 1950s cybernetic artworks of Nicolas Schöffer, through the 1968 exhibition “Cybernetic Serendipity” and Jack Burnham’s concept of Systems Aesthetics, to the more contemporary software and robotic artworks of Max Dean, Seiko Mikami, and others. A focus is placed on the work of Canadian artist David Rokeby who has explored the aesthetics of the human encounter and interaction with technical systems since the 1980s. The analysis aims at adding two further aspects of the aesthetics of machines to the list of five such aspects developed in the previous chapter: one is the aspect of “interactivity”, which adds the dimension of a charged dialogue and exchange between human and machine; and the other is the aspect of “machine autonomy”, which becomes a determining factor in the human experience of increasingly independent and self-referential technical systems.

Abstract Gilead et al. offer a thoughtful and much-needed treatment of abstraction. However, it fails to build on an extensive literature on abstraction, representational diversity, neurocognition, and psychopathology that provides important constraints and alternative evidence-based conceptions. We draw on conceptions in software engineering, socio-technical systems engineering, and a neurocognitive theory with abstract representations of gist at its core, fuzzy-trace theory.

Insight Into

Geological samples typically contain many minerals (phases) with multiple element compositions. A complete analytical description should give the number of phases present, the volume occupied by each phase in the bulk sample, the average and range of composition of each phase, and the bulk composition of the sample. A practical approach to providing such a complete description is from quantitative analysis of multi-elemental x-ray images.With the advances in recent years in the speed and storage capabilities of laboratory computers, large quantities of data can be efficiently manipulated. Commercial software and hardware presently available allow simultaneous collection of multiple x-ray images from a sample (up to 16 for the Kevex Delta system). Thus, high resolution x-ray images of the majority of the detectable elements in a sample can be collected. The use of statistical techniques, including principal component analysis (PCA), can provide insight into mineral phase composition and the distribution of minerals within a sample.
