The behaviour of an axisymmetric bubble in a pure liquid forced by an acoustic pressure field is analysed. The bubble is assumed to have a sharp deformable interface, which is subject both to surface tension and to Rayleigh viscosity damping. Two modelling regimes are considered. The first is a linearized solution, based on the assumption of small axisymmetric deformations to an otherwise spherical bubble. The second involves a semi-numerical solution of the fully nonlinear problem, using a novel spectral method of high accuracy. For large-amplitude nonspherical bubble oscillations, the fully nonlinear solutions show that a complicated resonance structure is possible and that curvature singularities may occur at the interface, even in the presence of surface tension. Rayleigh viscosity at the interface prevents singularity formation, but eventually causes the bubble to become purely spherical unless shape-mode resonances occur. An extended analysis is also presented for purely spherical bubbles, which allows for a more detailed study of the effects of resonance and the Rayleigh viscosity at the bubble surface.
The study aims to grasp the dynamic characteristics of paralinguistic communication during co-creation and has developed an analysis methodology by clustering the conversational patterns and determining the criteria more often observed in pre-resonance. The results suggest that pre-resonance is characterized by less silence, a rapid transition in exchanging ideas under one's initiative, and a conversation with equal amounts of utterances between both in a pair. This study reveals implications for better communication that lead to resonance, an essential phenomenon in collaborative design.
This chapter explores the interpersonal function of emoji as they resonate with the linguistic attitude and negotiation of solidarity expressed in social media posts. We have introduced a system network for describing the ways in which this resonance can occur, making a distinction between emoji which imbue the co-text with interpersonal meaning (usually through attitudinally targeting particular ideation) and emoji which enmesh with the interpersonal meanings made in the co-text (usually through coordinating with linguistic attitude). We then explain the more delicate options in this resonance network where emoji can harmonise with the co-text by either echoing or coalescing interpersonal meaning, or can rebound from the co-text, either complicating, subverting or positioning interpersonal meaning. Following this traversal of the resonance network we considered two important dimensions of interpersonal meaning noted in the corpus: the role of emoji in modulating attendant interpersonal meanings in the co-text by upscaling graduation and emoji’s capacity to radiate interpersonal meaning through emblematic usage as bonding icons.
We investigate the existence and branching patterns of wave trains in the mass-in-mass (MiM) lattice, which is a variant of the Fermi–Pasta–Ulam (FPU) lattice. In contrast to FPU lattice, we have to solve coupled advance-delay differential equations, which are reduced to a finite-dimensional bifurcation equation with an inherited Hamiltonian structure by applying a Lyapunov–Schmidt reduction and invariant theory. We establish a link between the MiM lattice and the monatomic FPU lattice. That is, the monochromatic and bichromatic wave trains persist near $\mu =0$ in the nonresonance case and in the resonance case $p:q$ where $q$ is not an integer multiple of $p$. Furthermore, we obtain the multiplicity of bichromatic wave trains in $p:q$ resonance where $q$ is an integer multiple of $p$, based on the singular theorem.
This chapter shifts the focus from principle to pragmatic concerns. It starts by considering a number of pragmatic maxims that apply to the enforcement of morality. These maxims limit the relevance of the more abstract principles discussed in this book and will suggest to some that a better approach would start first with the maxims and consider principles only when necessary. This chapter indirectly defends the principles-first approach adopted in this book by outlining what would be lost if this rival maxims-first approach were pursued. The chapter then turns to the problem of overcriminalization, to which the ethical environmentalism defended in this book may seem to be especially vulnerable. This problem points to the importance of identifying alternative enforcement methods to the criminal law, and the importance of comparative assessments of legal and social enforcement mechanisms. The chapter concludes by discussing the social fact of intractable disagreement over the content of morality in modern societies, and the limits, as well as the benefits, this fact presents to the project of ethical environmentalism.
In 1772 Joseph Banks recorded observations on the Hebridean island of Staffa. His most striking ‘discovery’ was a sea cave resembling a cathedral. Banks claimed the cave was known by the name of the mythical Irish warrior Fionn mac Cumhaill, or Fingal, to use the variant made famous by Macpherson’s Ossian poems. The publication of Banks’s findings prompted a small industry of travel writing that combined lithic observations with minstrelsy and national history. In 1797 the French geologist Barthélemy Faujas de Saint-Fond published his research on the topic, which suggested that the association with Ossian was the result of a misunderstanding: whereas the Gaelic for Fingal’s Cave would be ‘an-ua-fine’, the actual name was ‘an-ua-vine’, which translated as ‘melodious cave’. Far from settling the matter, Saint-Fond’s intervention only added to the mystique. In this chapter I argue that the cave’s fashionable status can be partly attributed to a series of re-soundings, by which printed texts and theatrical performances relayed aspects of on-site accounts to new readers and audiences. Where existing models of Romantic resonance have emphasized a correspondence between sound and thought, the fame of Fingal’s Cave emerges here as the result of almost mindless repetition.
A radical re-imagining of the relationship between sound and sense took place in Britain in the decades around 1800. This new approach reconfigured sound as central to understandings of space and temporality, from the diurnal rhythms of everyday life in the modern city to the 'deep time' of the natural world. At the same time, sound emerged as a frequently disruptive phenomenon, a philosophical and political problem, and a force with the power to overwhelm listeners. This is the first book devoted to the topic and brings together scholars from literary studies, musicology, history and philosophy through the interdisciplinary frameworks of sound studies and the history of the senses. The chapters pursue a wide range of subjects, from 'national airs' to the London stage, and from experiments in sound to new musical and scientific instruments. Collectively, they demonstrate how a focus on sound can enrich our understanding of Romantic-era culture. This title is also available as Open Access on Cambridge Core.
This study is aimed to understand the relationship between resonance and interpersonal phonetic communication during co-creation from the following points of view: linguistic functional factors and paralinguistic factors. The novice designers were assigned a concept generation task in pairs from the two nouns, “weather” and “stationery”. Linguistic function tags were contracted into five tag groups, Stuckness, Question, Seriousness, Proposition and Positiveness. The results suggest that phonetic communication in resonance showed significantly lower Stuckness and higher Positiveness towards the counterpart's utterances; Silence-based conversation was significantly observed when both were in creative states but had not reached resonance; Resonance was significantly more likely to occur with communication where one mainly spoke and the other also responded with utterances, neither one spoke in dominant amounts, or both spoke in equal amounts.
This study will contribute to understanding and facilitating resonance, which is an essential phenomenon in individual/interpersonal/group creativity, with practical implications, especially for co-creative concept generation and sustainable creative flow in collaborative design.
Newton’s laws and consideration of units are used to present and discuss the mass on a spring as an example of a harmonic oscillator, a mechanical oscillator with a sinusoidal time dependence. Both the transient solution, where the oscillator is started away from equilibrium and left on its own, and the driven solutions, where a sinusoidal driving force is applied, are presented. The quality factor, Q, is introduced, which characterizes the relative amount of damping forces present, such as those of friction or air drag. The quality factor is related to the number of oscillations that are made when left on its own and to the excitation bandwidth, the range of frequencies over which resonance is observed. Musically relevant examples include the ocarina, tuning fork, some speaker enclosures, and the phenomenon of sympathetic resonance.
The decade of the 1950s witnessed a great transformation in the compositional practice of Pierre Boulez. The usual narratives of serialism during this decade have tended to dwell on Boulez’s experiments with multiple serialism in Structure Ia (1951), which were tremendously short lived. His desire to expand the serial principle, however, did not end with them. Ensuing works, like Le Marteau sans maître (1952–5), Pli selon pli (1957–62/89), and the Third Piano Sonata (1955–7/63), which brought Boulez to the pinnacle of his reputation within the European circle of composers, are those that truly redefined serialism. Through this redefinition, serialism remained an important element of Boulez’s compositional technique until the end of his career. This chapter shows that Boulez’s serialism was an essential forerunner of future trends, rather than a culmination of an abandoned practice, resulting in works and approaches that opened up new avenues for composition.
Disenchantment is doubtless a serious part of a modern attitude to nature. Even Lucretius’ ancient materialism gave good reasons for celebrating nature as a random interplay of forces without seeking a deeper meaning within. In addition, experiences of a silent nature and personal accounts by the deaf have become common. Nevertheless, human consciousness exhibits phenomena that allow us to speak of a voice of nature; closer examination of these phenomena of resonance and empathy provides good reasons for an idealistic understanding of the enchantment of nature. In the human mind, the spirit of the universe awakens unto itself.
Resonance is known as an important phenomenon where individual creative moments resonate with each other during co-creation. The purpose of this study is to capture this co-creative moment as a resonant cognitive status with biosignal indicators. The authors conducted an experiment in which pairs of participants work on concept generation from two nouns and measured their dynamic creative status both subjectively and objectively with biosignal indicators fEMG and EOG. This study will help to understand co-creative cognitive phenomena and to improve the co-creative design process.
Inspired by the reinvigorating theory of Wai-Chee Dimok and Rita Felski, I argue that The Tempest resonates with current theory and performance of Indigenous resurgence in North America. With reference to the work of Indigenous performance theorist Floyd Favel, political thinkers Leanne Simpson and Glen Sean Coulthard, and to plays and performances by Yvette Nolan, Monique Mojica, Kevin Loring, and Spiderwoman Theatre, I describe resurgence as culturally recuperative practices of movement on the land that make it feel more comfortable, establish an Indigenous sense of sovereignty, and diminish shame. I emphasize the ways in which the physical and imaginative mobilities of Shakespeare’s Boatswain and Gonzalo anticipate the comforting—and insurgent—land-oriented movements of Caliban. I argue that Caliban’s sense of natural sovereignty is understood better in terms of free and secure mobility than in terms of rule or possession.
An analytical and a numerical study on coupling in microstrip transmission line (MTL) are reported for different split-gap orientations of a single gap square-shaped split-ring resonator (SRR). Taking both magnetic and electric couplings and adopting Lagrangian formulation for this coupled system, mathematical relations are found for each orientation of SRR to determine the connection between coupling co-efficient and resonant mode frequency. It is shown that coupling results in higher resonance frequency when the SRR, with parallel split-gap, has the gap far from the MTL. But, a lower resonance frequency is obtained when the SRR is placed at shorter distances with parallel split-gap near to the MTL. Again, for perpendicular split-gap orientation of SRR, the resonant frequency is found in terms of an effective coupling co-efficient; at shorter distances it is found to be lower than the fundamental resonance frequency of uncoupled SRR and an opposite effect is obtained at longer distances. Using CST Microwave Studio, the resonance frequency for each split-gap orientation of SRR is also studied as a function of separation between MTL and SRR. It is observed that this phenomenon strongly depends on SRR side-length, substrate height, and separation between MTL and SRR.
Chapter 3 focuses on Paul Auster’s autobiographical diptych (Winter Journal (2012) and Report from the Interior (2013)) which are both entirely written in the second-person pronoun. It demonstrates why the pronoun is particularly fitting a choice in the general economy of life writing and memory gathering of Auster’s enterprise. The second-person pronoun is also shown to be instrumental in the interpersonal connection Auster is ethically constructing with his readers, making his own personal experience somehow shareable. ‘You’ positions the reader in a most singular way in the intrapersonal dialogue Auster is having with himself, placing her close to his deictic centre, as a sort of co-habitant of his mental space. The American author’s autobiographical works most unusually written in a doubly subjective ‘you’ indeed pragmatically invites the reader to meet him half way via the ethical vector that the second person represents.
A firm grounding in single-input, single-output feedback theory leaves the reader well positioned to jump off into many other topics.Modern control theory as it is normally presented is such a blizzard of linear algebra that it can seem at first to have nothing at all to do with what appears in this book.The first section of this chapter offers a short bridge to that world. Next, this chapter treats an extremely common misunderstanding about oscillation, whose genesis is often an overinterpretation of phase margin. Finally, many students of "classical" control theory find themselves utterly at sea when it comes to applying their hard-earned knowledge to digitally controlled systems. The final section of this chapter aims to bridge that gap.
In this article, we present two efficient closed-form models to examine thoroughly the dependence of resonant frequency, quality factor, probe reactance, input impedance, bandwidth, and gain on parameters such as patch radius, probe location, substrate electrical parameters, and air gap of a coax probe-fed circular patch antenna. The implementation of these models is very easy and the computation cost is very low. The proposed models show excellent agreements with experimental and simulation results. We have also investigated experimentally the gain patterns of a suspended substrate circular patch antenna.
This chapter presents how a phenomenological approach can help developing a more integral and relational understanding of embodied and resonant practices of new work in organisations. Building on seeing work as situationally and temporally placed, the concept of ‘inter-practice’ will be discussed. In such relational practices material, economic and socio-cultural, political dimensions come together. Based on a Merleau-Pontyian inspired phenomenology of embodied practicing, the processual concept of “inter-practice” is presented. Afterword the relational mode of ‘resonance’ as developed by Rosa will be presented and critically discussed and by concluding some implications and perspectives offered.
Chapter 8 offers a development of thinking about social influence by considering the role of modern mass mediation. The chapter starts by looking at the role of communication in cultivating social representations of the world, both in formal and informal ways. It proceeds by reviewing several hypotheses concerning mass media effects, including diffusion, knowledge gap, cultivation, diegetic prototyping and serial reproduction. The chapter further considers the extended role of mass mediation in agenda setting, priming and framing issues for public consumption. The idea of a 'spiral of silence' best illustrates how mass media effect analysis adds a second level of analysis to the phenomena of social influence: the theory explicitly elaborates the notion of conformity in the context of modern mass mediation. Hence, the chapter asks a question rather than offering the answer: how do media effect theories elaborate social influence simultaneously on two levels, that of interaction and that of mass mediation. For example, how does this tie in with the rediscovery of crowds as 'internet bubbles' and 'echo chambers dominated by conformity bias and motivated reasoning'?
The relations between embodiment and temporality reach from the micro-temporality of conscious experience to the enactment of human existence. First, the basic internal time consciousness is marked by the rhythmicity of vital processes (heart beat, respiratory rhythm, daily periods, etc.). Moreover, the bodily drives, urges, and needs, which may be subsumed under the term conation, crucially determine the future-directed temporality of primary experience. On the other hand, the body forms an extract of sensorimotor and affective experience which are sedimented in implicit or body memory, thus shaping an individual's capacities and dispositions. Finally, existential temporality is essentially characterized by the vital processes of birth, growth, aging, and dying.
Body, time, and intersubjectivity are equally interconnected. First, interbodily resonance establishes the primary experience of the shared present, beginning in the child's early development. Thus, a basic contemporality emerges, which later continues in social synchronizations and temporal orders as the basis of social life. However, this temporal alignment is also subject to desynchronizations, for example, in backlogs of tasks, in guilt, remorse, or grief – situations that require processes of psychosocial resynchronization.
All these interconnections are subject to various kinds of disturbances which are also found in psychopathology and thus crucially determine the emergence and course of mental disorders.
