Measurement of Time
Measurement of Time M.Y. ANAND, B.A. KAGALI* Department of Physics, Bangalore University, Bangalore 560056 *email: [email protected] ABSTRACT Time was historically measured using the periodic motions of the sun and stars. Various types of sun clocks were devised in Egypt, Greece and Europe. Different types of water clocks were assembled with ever greater accuracy. Only in the seventeenth century did the mechanical clock with pendulums and springs appeared. Accurate quartz clocks and atomic clocks were developed in the first half of the twentieth century. Now we have clocks that have better than microsecond accuracy. This article gives a brief account of all these topics. Keywords: Sun clocks, Water clocks, Mechanical clocks, Quartz clocks, Atomic clocks, World Time, Indian Standard time We all know intuitively what time is. It can be civilizations relied upon the apparent motion of roughly equated with change or motions.

Usually, there is a need for a second person to actuate the bowl. Addressing these limitations, we built an electronic device, named eBowl, which can mimic the acoustics of Tibetan bowls, and beyond that, can produce a wide range of other sounds. Furthermore, it can be used for relaxation and sound massage without the need for a second person. The eBowl generates auditory beats that are in EEG alpha frequency range, which can cause brainwave entrainment and lead to relaxation. User tests measuring Figure 1.

Large Scale Sound Installation Design: Psychoacoustic Stimulation
LARGE SCALE SOUND INSTALLATION DESIGN: PSYCHOACOUSTIC STIMULATION An Interactive Qualifying Project Report submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science by Taylor H. Andrews, CS 2012 Mark E. Hayden, ECE 2012 Date: 16 December 2010 Professor Frederick W. Bianchi, Advisor Abstract The brain performs a vast amount of processing to translate the raw frequency content of incoming acoustic stimuli into the perceptual equivalent. Psychoacoustic processing can result in pitches and beats being “heard” that do not physically exist in the medium. These psychoac- oustic effects were researched and then applied in a large scale sound design. The constructed installations and acoustic stimuli were designed specifically to combat sensory atrophy by exer- cising and reinforcing the listeners’ perceptual skills. i Table of Contents Abstract ............................................................................................................................................ i Table of Contents ............................................................................................................................ ii Table of Figures ............................................................................................................................. iii Table of Tables .............................................................................................................................. iv Chapter 1: Introduction ................................................................................................................. -

SECURE ENTERPRISE TIME SYNC WHITEPAPER SERIES TimeKeeper’s Competitive Survey Introduction The TimeKeeper® suite of products are more accurate, more reliable and far more capable than CAPEX-free open source alternatives. TimeKeeper has a lower OPEX than alternatives, but more importantly, TimeKeeper has features found nowhere else. These features include the ability to verify time is correct, compare against many time sources, report when time is incorrect or when time sources fail, and much more. Standard logging and integration provide guarantees of accuracy whenever proof is needed in the future. Some TimeKeeper customers previously built large in-house projects to try to make alternative solutions fit their needs. These expensive and very limited solutions were abandoned once they saw TimeKeeper gave them all they needed and more out of the box, saving valuable time and resources. TimeKeeper in use TimeKeeper hardware and software is in use by financial institutions of all sizes, from exchanges and very throughout Wall Street & large investment banks to small “prop shops”. TimeKeeper is there because after rigorously evaluating the globally product, customers found it gave them capabilities they simply could not get anywhere else. In addition, TimeKeeper support is far better than any of the competition. A few comments from our customers: “KCG has been using TimeKeeper Client and Server Software for two years in our trading environment with great success. TimeKeeper delivers accurate time, and has helped us to reduce operational risk with its built-in failover and event notification. We use TimeKeeper Client Software on our servers, using NTP or PTP to sync them to our GPS Based TimeKeeper Servers.” – Steve Newman, Managing Director, Corporate IT and Infrastructure, KCG “Technology is readily accessible for synchronizing to the microsecond, and there is no excuse for not having this in place today. -
Brainwave Entrainment a Guide on All You Need to Know
Brainwave Entrainment A guide on all you need to know 1. The Science behind Brainwave Entrainment 2. What Are Brainwaves 3. Why Are Brainwaves Important 4. What Is Brainwave Entrainment 5. Brainwave Entrainment with Audio 6. Brainwave Entrainment History & Significant Studies 7. Practical Brainwave Entrainment 8. How to Get Started with Brainwave Entrainment 9. Research & Further Reading www.dermaspa.co.za 1. The Science behind Brainwave Entrainment can be explained quickly and easily. To begin, let's start by understanding what "brainwaves" are. We all experience different states of mind each day: states such as sleep, focus, or creativity, for example. Every state of mind has a unique electrical signature that can be detected in the brain. These signatures are known as “brainwaves.” Using specialized equipment, these waves (or frequencies) can be measured and recorded, allowing us to map what brainwaves are present during certain key states of mind. "Brainwave Entrainment" is the process of (typically) using audio and/or visual stimulation to actually change brainwave patterns. By changing your brainwave patterns, you can actually recreate certain states of mind - again, such as sleep, focus or creativity. Usually, this works by listening to a particular brainwave pattern (a specific pulsed frequency, encoded in audio). The brain then follows (entrains) to that pattern, and as a result, changes your state of mind. Quick example: Brainwave readings (with an EEG machine) have shown that brainwaves of 2Hz occur when an individual is asleep. Scientists can create special audio recordings, which contain an encoded 2Hz frequency. While listening to such audio, the brain naturally follows (entrains) toward that 2Hz frequency, lowering its brainwave patterns. -

Open-Loop Neurofeedback Audiovisual Stimulation: A Pilot Study of Its Potential for Sleep Induction in Older Adults Abstract This pilot study tested the efficacy of a 30-min audio-visual stimulation (AVS) program for the treatment of chronic insomnia in older adults. Chronic insomnia has been conceptualized as entailing increased cortical high frequency EEG activity at sleep onset and during NREM sleep. We hypothesized that an AVS program gradually descending from 8 to 1 Hz would potentially reduce the excessive cortical activation that is thought to contribute to difficulties with initiating and maintaining sleep. -
