Orchestral Scores

Инструментовкой сегодня занимаются не только композиторы, создающие оркестровые партитуры, но и широкий круг музыкантов - профессионалов и любителей, работающих в различных жанрах электронной музыки. Электронная инструментовка имеет много общего с ее традиционным видом, поскольку в обоих случаях решаются одинаковые задачи: реализация колористического потенциала исходного текста, выстраивание композиционной формы с помощью выделения ее разделов, выстраивание фактуры путем заполнения акустического пространства и прорисовки ее пластов. Различия же обусловлены разной природой музыкального материала. В одном случае - это звучание оркестровых инструментов в концертном зале или на открытом воздухе. В другом - это множество синтезированных звуков в условиях виртуальной акустики, которая может быть представлена в самых разных вариантах. Электронная инструментовка, опираясь на сложившиеся в многовековой академической практике приемы, обогащается за счет использования новых звуков и возможностей управления виртуальным пространством их развертывания. Today, not only composers who create orchestral scores are engaged in instrumentation, but also a wide range of musicians-professionals and amateurs working in various genres of electronic music. Electronic instrumentation has a lot in common with its traditional form, since in both cases the same tasks are solved: realizing the color potential of the source text, building a compositional form by highlighting its sections, building a texture by filling the acoustic space and drawing its layers. The differences are due to the different nature of the sound material. In one case, it is the sound of orchestral instruments in a concert hall or in the open air. In the other case, it is a variety of synthesized sounds in a virtual acoustic environment, characterized by diversity and variability. Therefore, electronic instrumentation, based on the techniques developed in centuries-old practice, is enriched by the use of these new sounds and the ability to manage the virtual space of their deployment.

Ultrasonic Thickness

Ultrasonic thickness gauges are easy to operate and reliable, and can be used to measure a wide range of thicknesses and inspect all engineering materials. Supplementing the simple ultrasonic thickness gauges that present results in either a digital readout or as an A-scan with systems that enable correlating the measured values to their positions on the inspected surface to produce a two-dimensional (2D) thickness representation can extend their benefits and provide a cost-effective alternative to expensive advanced C-scan machines. In previous work, the authors introduced a system for the positioning and mapping of the values measured by the ultrasonic thickness gauges and flaw detectors (Tesfaye et al. 2019). The system is an alternative to the systems that use mechanical scanners, encoders, and sophisticated UT machines. It used a camera to record the probe’s movement and a projected laser grid obtained by a laser pattern generator to locate the probe on the inspected surface. In this paper, a novel system is proposed to be applied to flat surfaces, in addition to overcoming the other limitations posed due to the use of the laser projection. The proposed system uses two video cameras, one to monitor the probe’s movement on the inspected surface and the other to capture the corresponding digital readout of the thickness gauge. The acquired images of the probe’s position and thickness gauge readout are processed to plot the measured data in a 2D color-coded map. The system is meant to be simpler and more effective than the previous development.

This article compares two different Brazilian translated versions of Toni Morrison's novel Beloved: the first published in 1994, the other in 2007, both as Amada. The analysis concentrates on the speech delivered by Baby Suggs, in which she exhorts her listeners to care for their bodies. The main idea behind this article is that Beloved and the Amadas converse or talk, thus performing signifyin(g), a concept which, in Henry Louis Gates's words, explains how intertextual conversation happens through “repetition and revision, or repetition with a signal of difference” (xxiv). Its general theoretical foundations include interconnections involving several instantiations of signifyin(g): between Black nationalism and negritude, postcolonialism and African Americanism. In its specific concern with translation, the conversation that the source keeps with the target texts involves two translation theories: fluency and resistance; two kinds of translating interventions: omission and addition; and three types of strategies: syntactic, semantic, and pragmatic. These distinct categories help readers grasp translation as a continuum by means of which a specific source text encounters its target equivalents and, then, returns to its origin.

American studies has developed excellent critiques of post-1945 imperial modes that are grounded in human rights and Enlightenment liberalism. But to fully gauge US violence in the twenty-first century, we also need to more closely consider antiliberal cultural logics. This essay traces an emergent mode of white nationalist militarism that it calls Identitarian war. It consists, on the one hand, of a formal ideology informed by Identitarian ethno-pluralism and Carl Schmitt, and, on the other, an openly violent white male “structure of feeling” embodied by the film and graphic novel 300, a key source text for the transatlantic far right.

Dense subregion (subgraph & subtensor) detection is a well-studied area, with a wide range of applications, and numerous efficient approaches and algorithms have been proposed. Approximation approaches are commonly used for detecting dense subregions due to the complexity of the exact methods. Existing algorithms are generally efficient for dense subtensor and subgraph detection, and can perform well in many applications. However, most of the existing works utilize the state-or-the-art greedy 2-approximation algorithm to capably provide solutions with a loose theoretical density guarantee. The main drawback of most of these algorithms is that they can estimate only one subtensor, or subgraph, at a time, with a low guarantee on its density. While some methods can, on the other hand, estimate multiple subtensors, they can give a guarantee on the density with respect to the input tensor for the first estimated subsensor only. We address these drawbacks by providing both theoretical and practical solution for estimating multiple dense subtensors in tensor data and giving a higher lower bound of the density. In particular, we guarantee and prove a higher bound of the lower-bound density of the estimated subgraph and subtensors. We also propose a novel approach to show that there are multiple dense subtensors with a guarantee on its density that is greater than the lower bound used in the state-of-the-art algorithms. We evaluate our approach with extensive experiments on several real-world datasets, which demonstrates its efficiency and feasibility.

This paper proposes an object classification method using a flexion glove and machine learning. The classification is performed based on the information obtained from a single grasp on a target object. The flexion glove is developed with five flex sensors mounted on five finger sleeves, and is used for measuring the flexion of individual fingers while grasping an object. Flexion signals are divided into three phases, and they are the phases of picking, holding and releasing, respectively. Grasping features are extracted from the phase of holding for training the support vector machine. Two sets of objects are prepared for the classification test. One is printed-object set and the other is daily-life object set. The printed-object set is for investigating the patterns of grasping with specified shape and size, while the daily-life object set includes nine objects randomly chosen from daily life for demonstrating that the proposed method can be used to identify a wide range of objects. According to the results, the accuracy of the classifications are achieved 95.56% and 88.89% for the sets of printed objects and daily-life objects, respectively. A flexion glove which can perform object classification is successfully developed in this work and is aimed at potential grasp-to-see applications, such as visual impairment aid and recognition in dark space.

Theological Thought

Religious notions have long played a role in epistemology. Theological thought experiments, in particular, have been effective in a wide range of situations in the sciences. Some of these are merely picturesque, others have been heuristically important, and still others, as I will argue, have played a role that could be called essential. I will illustrate the difference between heuristic and essential with two examples. One of these stems from the Newton–Leibniz debate over the nature of space and time; the other is a thought experiment of my own constructed with the aim of making a case for a more liberal view of evidence in mathematics.

Ketene Acetal

The behaviour of various types of polar dienes towards halogenated ortho quinones has been investigated in a number of representative cases. As compared to the commonly used para analogues, o-quinones provide a wide range of products that indicate a keener response to the nature, number, and position of substituents on both reactants. 3-Halogenated-o-naphthoquinones 1 and 2 react smoothly with a representative vinologous ketene acetal 3, vinylketene acetals 4 and 5, and a monooxygenated diene 6 to provide variously substituted phenanthrenequinones 7–11. Only monooxygenated dienes on the other hand add to o-benzoquinones 14–16 and give convenient syntheses of the corresponding o-naphthoquinones 18–20. Keywords: cycloaddition, o-naphthoquinones, phenanthrenequinones, regiospecificity.

Abstract Reexamination of a wide range of documents surrounding the twenty-second, twenty-fourth, and twenty-fifth sessions of the Council of Trent reveals that delegates strived officially to say as little as possible about music: only that secular or impure elements should be eliminated and that specific issues should be settled locally, by individual bishops and provincial synods. But, beginning with Gustave Reese, several scholars have misleadingly strung together a preliminary canon, stressing textual intelligibility, which was never approved in the general congregations, and the few lines that actually supplanted it, concerned only with the elimination of lasciviousness. On the other hand, a largely unrecognized or misunderstood attack on church polyphony did occur at the less familiar twenty-fifth session, when Gabriele Paleotti may have attempted to suppress elaborate music in female monasteries. Although this attempt was rejected in the general congregations, its restrictions were subsequently revived by local authorities such as Paleotti and Carlo Borromeo in their own dioceses. In the Council's immediate aftermath, reformers such as Paleotti and Borromeo once again focused on the issue of intelligibility, affording it a quasi-official status that seems to have quickly become widely accepted as “iuxta formam concilii.”
