Significance of Beating Observed in Earthquake Responses of Buildings
SIGNIFICANCE OF BEATING OBSERVED IN EARTHQUAKE RESPONSES OF BUILDINGS Mehmet Çelebi1, S. Farid Ghahari2, and Ertuğrul Taciroǧlu2 U.S. Geological Survey1 and University of California, Los Angeles2 Menlo Park, California, USA1 and Los Angeles, California, USA2 Abstract The beating phenomenon observed in the recorded responses of a tall building in Japan and another in the U.S. are examined in this paper. Beating is a periodic vibrational behavior caused by distinctive coupling between translational and torsional modes that typically have close frequencies. Beating is prominent in the prolonged resonant responses of lightly damped structures. Resonances caused by site effects also contribute to accentuating the beating effect. Spectral analyses and system identification techniques are used herein to quantify the periods and amplitudes of the beating effects from the strong motion recordings of the two buildings. Quantification of beating effects is a first step towards determining remedial actions to improve resilient building performance to strong earthquake induced shaking. Introduction In a cursory survey of several textbooks on structural dynamics, it can be seen that beating effects have not been included in their scopes. On the other hand, as more earthquake response records from instrumented buildings became available, it also became evident that the beating phenomenon is common. As modern digital equipment routinely provide recordings of prolonged responses of structures, we were prompted to visit the subject of beating, since such response characteristics may impact the instantaneous and long-term shaking performances of buildings during large or small earthquakes. The main purpose in deploying seismic instruments in buildings (and other structures) is to record their responses during seismic events to facilitate studies understanding and assessing their behavior and performances during and future strong shaking events. -

Can You Reflect Sound? ECHO TUBE
Exhibit Sheet Can you reflect sound? ECHO TUBE (Type) Ages Topic Time Science 7-14 Sound <10 mins background Skills used Observation, Curiosity Overview for adults Echo Tube is a 15 metre hollow tube. When you shout or make a sound into the tube, it is reflected off the end of the tube and comes back to you. You hear this as an echo. The tube has two flaps within it that you can open or close, changing the length of the tube and the length of time it takes the echo to bounce back to you. What’s the science? Sound travels through the air as sound waves. When these sound waves meet a surface, they are reflected back to where they came from. Sound travels at 330 meters per second in air, which is much slower than light. This means that when light is reflected, we see its reflection instantly but when sound is reflected, we can hear the delay as an echo. The surface that the sound bounces off doesn’t have to be solid. The echo tube is open at both ends. The air pressure inside the tube is higher than the air pressure outside. When the sound wave meets the open end of the tube, this change in pressure causes a wave to be reflected down the tube from the open end. Science in your world Echoes from the open ends of tubes are what make musical instruments such as horns and trumpets work. The sound wave reflects up and down the tube from the open ends. -

Does Halo Insulation Work As Soundproofing?
Does Halo Insulation Work as Soundproofing? You’re probably familiar with Halo’s strengths as an insulation product that slashes energy costs by keeping room temperatures at a comfortable level. But what about noise control — can Halo also add comfort by reducing sound transmission? It turns out that it can, although Halo’s performance as a soundproofing material is not as impressive as its array of thermal benefits. This post will talk about the several ways in which Halo’s products can be used to manage sound in a building. Managing Sound Transmission vs. Echo © 2018 Logix Insulated Concrete Forms LTD | 855-350-4256 (HALO) Does Halo Insulation Work as Soundproofing? Soundproofing and sound absorption are 2 distinct processes. Soundproofing means blocking soundwaves from traveling from one space to the next, whereas sound absorption refers to reducing echo. One of the ways to soundproof a space is by decoupling the partition. This practice requires two layers of solid material — gypsum, concrete, or glass — with an air gap between them. The solid layer facing the sound’s origin acts as a conductor to the soundwaves until they reach the air cavity, interrupting the waves’ direct path. This way, the soundwaves are far weaker when they reach the solid layer on the other side of the partition. Unfortunately, decoupling alone is not enough to block soundwaves of all frequencies. That’s why other strategies, like adding mass, damping the partitions, and improving absorption, are crucial to sound control. Absorption, for instance, boosts the soundproofing performance of decoupled walls and improves the sound quality in the space from which the noise is coming. -

Contrast Echo on Evaluation of Cardiac Function – Basic Principles
Contrast echo and evaluation of cardiac function: basic principles Y. Yotov University Hospital “St.Marina” Varna, Bulgaria EAE Teaching Corse, 5-7 April 2012, Sofia, Bulgaria Contrast in echocardiography: Why? • To delineate the endocardium by cavity opacification. – for assessment of global and regional systolic function, LV volumes and ejection fraction. – LV opacification (LVO) for improved visualisation of structural abnormalities – enhanced visualisation of wall thickening during stress echocardiography • To enhance Doppler flow signals from the cavities and great vessels. • To determine myocardial ischaemia and viability using myocardial perfusion contrast echocardiography (MCE) • Quantification of the coronary flow reserve, which has prognostic value in various disease conditions TISSUE: Incident frequency results in equal and opposite vibration (i.e. LINEAR RESPONSE) MICROBUBBLES: Can only become so small but can expand to a greater degree, resulting in unequal oscillation (i.e. NON-LINEAR RESPONSE) This results in asymmetrical vibrations which produce harmonic frequencies http://www.escardio.org/communities/EAE/contrast-echo-box/ TISSUE HARMONIC IMAGING Principles of Contrast echocardiography Blood appears black on conventional two dimensional echocardiography, not because blood produces no echo, but because the ultrasound scattered by red blood cells at conventional imaging frequencies is very weak—several thousand times weaker than myocardium—and so lies below the displayed dynamic range. Stewart MJ. Heart. 2003; 89(3): 342–348. • It is a remarkable coincidence that gas bubbles of a size required to cross the pulmonary capillary vascular bed (1–5 mm) resonate in a frequency range of 1.5–7 MHz, precisely that used in diagnostic ultrasound.

Based hence a nonlinear phase response versus frequency, and various on ASP requirements, found to be phaser resolution, absolute phaser technologies are discussed and compared. Real-time Fourier transformation (RTFT) is derived as one of the most bandwidth and magnitude balance, it then describes novel fundamental ASP operations.
