Pulsation in Architecture highlights the role of digital design as the catalyst for a new spatial sensibility related to rhythmic perception. It proposes a novel critical reception of computational architecture based on the ability of digital design to move beyond mere instrumentality, and to engage with core aspects of the discipline: the generative engine of digital architecture reinvigorates a discourse of part-to-whole relationships through the lens of rhythmic affect. There is a paradigm shift in spatial perception due to the intense use of computational techniques and the capacity to morph massive amounts of data in spatial patterns; rhythm plays a pivotal role in the articulation of the topology of buildings, generating the atmospheric character that induces moods and throbbing sensations in space. Pulsation introduces the fundamental animate capacity of living form and reshapes our perception of architectural space across the multiple scales of a project, from digital inception to fabrication. An emerging thread of rhythmic sensibility loosely binds a survey of contemporary design practices, including contributions by Peter Eisenman, Jeff Kipnis, Greg Lynn, UNStudio, Preston Scott Cohen, Reiser + Umemoto, Asymptote, Ali Rahim, Hernan Diaz Alonso, Ruy Klein, Gage / Clemenceau, NOX, Evan Douglis Studio, kokkugia, and MONAD Studio.

At many stages of their lives, stars exhibit variability due to pulsations or oscillations. These oscillations give us a window to ‘inside the star’, to infer its interior structure and composition, and to test the physics of stellar models. The calibration of stellar luminosity with pulsation period allows us to measure distances within the Milky Way and to nearby galaxies. This volume describes the latest observational and theoretical research and remaining challenges for understanding pulsating variable stars of all types.

Since the 1970’s, an increasing amount of specialized research has focused on the problems created by instability of internal flow in hydroelectric power plants. However, progress in this field is hampered by the interdisciplinary nature of the subject, between fluid mechanics, structural mechanics and hydraulic transients. Flow-induced Pulsation and Vibration in Hydroelectric Machinery provides a compact guidebook explaining the many different underlying physical mechanisms and their possible effects. Typical phenomena are described to assist in the proper diagnosis of problems and various key strategies for solution are compared and considered with support from practical experience and real-life examples. The link between state-of the-art CFD computation and notorious practical problems is discussed and quantitative data is provided on normal levels of vibration and pulsation so realistic limits can be set for future projects. Current projects are also addressed as the possibilities and limitations of reduced-scale model tests for prediction of prototype performance are explained. Engineers and project planners struggling with the practical problems will find Flow-induced Pulsation and Vibration in Hydroelectric Machinery to be a comprehensive and convenient reference covering key topics and ideas across a range of relevant disciplines.

This outstanding thesis by Dominic Bowman provides a thorough investigation of long-standing questions as to whether amplitude modulation is astrophysical, whether it offers insights into pulsating stars, and whether simple beating of modes with stable amplitudes is unrecognised because of a lack of frequency resolution. In this thesis, the author studied a uniform sample of 983 delta Scuti stars—the most common type of main-sequence heat engine pulsator—that were observed nearly continuously for 4 years at stunning photometric precision of only a few parts per million by the Kepler space mission. With no mission planned to supersede the Kepler 4-year data set, this thesis will stand as the definitive study of these questions for many years. With revolutionary photometric data from the planet-hunting Kepler space mission, asteroseismic studies have been carried out on many hundreds of main-sequence solar-type stars and about 10,000 red giants. It is easy to understand why those stochastically driven stars have highly variable amplitudes. Over much of the rest of the Hertzsprung–Russell (HR) diagram, stellar pulsations are driven by heat mechanisms, which are much more regular than the stochastic driving in solar-like pulsators. Yet for decades, amplitude and frequency modulation of pulsation modes have been observed in almost all types of heat-driven pulsating stars. The author shows that the amplitude and frequency modulation are astrophysical, and he has investigated their implications and prospects to provide new insights into the delta Scuti stars and the many other types of heat-engine pulsators across the HR diagram.

Spanda is the vibratory dynamism of the absolute consciousness. In the first section of his commentary, Kṣemarāja presents spanda as identical with the essential self of each person. The second section presents a methodology that allows access to the world of spanda yoga. The third section describes the spiritual powers attained by the realization of spanda. Through modern physics, we have grown accustomed to thinking of physical reality as waves of energy--as the matter-energy continuum. Tantric Shaivism presents the full matrix of energy pulsation of which physical reality is only a part. From the relatively superficial perceptions of the senses to the progressively subtle forms of inner awareness, a unified spectrum of spanda leads inward until the most delicate and powerful tendrils of individuality merge with the infinitely rapid vibration of the ultimate consciousness. The text prescribes a continuous refinement of perception in order for that aspect of spanda which continuously subsides into infinity to be discovered in the awareness of the practitioner. Through prescribed use of mantra, the yogi develops a continuous attentiveness to the presence of the spanda--the spanda that reveals itself to her as an ecstatic flashing forth within her own awareness. The Guru enlivened mantra leads the yogi through the vibratory spectrum of awareness to the ever subtler domains within. As this occurs, the surface word-form of the mantra falls away and only the original lively pulsation of enlightenment is left. At a certain definite point, the individual awareness is permanently caught up in this subtle pulsation of the ultimate. It then transcends all of the relative spatial distinctions of inner and outer, higher and lower, above and below. The nondimensional, global encompassing of the individuality by the absolute consciousness is the state of jivanmukti, the goal of the tantric practice prescribed by the Spanda Karikas.

In this Symposium, researchers specializing in pulsation, rotation, magnetic fields and stellar winds are brought together for the first time in order to broaden our understanding of O and B stars. Thanks to advances in digital spectroscopy, new types of pulsating B stars have been discovered. The pulsations can be understood in terms of the recent revision of metal opacities, but the effects of rapid rotation and magnetic fields need further study. Observations in the UV and X-ray regions demonstrate that many B and Be stars show other activity, besides pulsation which is not yet understood. The reason for the enhanced mass loss in Be stars is a question which dominates the Symposium and which remains unanswered, although it is surely to be found in activity at or near the photosphere coupled with rotation. It is shown that the geometry of the circumstellar envelopes around Be stars is indeed a flattened disk as they can now be optically resolved. The variability of radiatively-driven winds from O and B stars are likely related to the rotation of the star. This underlines the central theme of the book: that the various phenomena seen in these stars cannot be studied in isolation.

Avec l’aide de Dylan Gilmore, son mystérieux compagnon de classe, Faith Daniels découvre qu’elle peut déplacer des objets par la force de sa pensée. Ce talent télékinésique s’appelle la «pulsation», et Dylan le possède aussi. Dans des scènes d’action palpitantes, Faith fait la démonstration de son aptitude à se servir de la pulsation contre un groupe de télékinésistes si puissants qu’ils peuvent écraser leurs adversaires en arrachant des lampadaires, en lançant des rochers ou en changeant la trajectoire d’un marteau projeté à toute vitesse pour le transformer en une arme mortelle. Mais même avec son talent peu commun, Faith risque d’avoir du mal à maîtriser son esprit et son coeur. Si elle veut s’allier à Dylan pour sauver le monde, elle devra contrôler le pouvoir de l’un et de l’autre. La trilogie de Patrick Carman illustre de façon éblouissante la puissance de l’esprit et de l’amour.

Stellar mass loss is an essential part of the cycling of material from the interstellar medium into stars and back, and must be understood if we are to model processes on galactic to cosmological scales. The study of stellar winds and the effects of stellar mass loss has reached a particularly exciting stage where observational capabilities are increasingly able to provide interesting constraints on models and theories. Recent resu1ts from theoretical and observational work for both hot and cool stars with substantial winds have led to the suggestion that a combination of pulsation with other mechanisms makes for particularly efficient mass loss from stars. This provided the original motivation for the organization of this workshop. The conference was organized along relatively conventional lines according to the types of objects being scrutinized. However the true unity of the proceedings comes from the interplay of the mechanisms involved. For example, for the cool, luminous Mira variables, pulsation leads to shock waves that extend the atmosphere, enhancing dust formation; radiation pressure on dust drives the wind, cooling the atmosphere and in some cases suppressing the shocks. Similarly for the Be stars, both pulsation (in this case, non-radial) and radiation pressure (due to UV resonance lines) are expected to be important, and this expectation is at least qualitatively borne out by the observations.
