Investigation of the factors affecting the period of vibration of a weighted cantilever Introduction The aim of the experiment is to find out how the period T of vibration of a weighted cantilever depends on the vibrating length L. Hypothesis: Assume the relationship between the vibrating period T and vibrating length L is in accord with the equation: T=kLn, where k and n are both constant values. According to the hypothesis, the vibrating period T and vibrating length L is a linear relationship
Mitchell McKay Annotated Bibliography Taping is a common practice that has been used by medical professionals for years.1 Over time, new treatments or devices are presented to the public with the promotion of being able to help people. One specific treatment or device that has been used is Kinesio tape. It was designed by a “Japanese chiropractor, Kenzo Kase in 1980...it is approximately the same thickness as the epidermis...it has heat-activated glue...is able to stretch to 140% of its resting
such as the X-ray, magnetic particle, ultrasound etc., are limited to detecting damage on or near the surface of structures, the need for global damage detection techniques, which can be used for complex structures, has resulted in development of vibration-based damage detec- tion methods (VBDD). The
• Damping Effects of the Passive Control Devices on Structural Vibration Control: TMD, TLC and TLCD for Varying Total Masses Three passive vibration control devices that consist of Tuned Mass Damper, Tuned Liquid Damper and Tuned Liquid Column Damper are experimentally investigated in this study. A scaled three-story steel building structure coupled with each device is employed to evaluate the damping effect of each controller. This research experimentally presents that the mass and damping of passive
Introduction To understand how an accelerometer works, one must first understand the concept of vibration. One example of vibration is sound. When an object vibrates and creates a disturbance in a medium, it creates a sound wave. The sound wave travels in sinusoidal form with certain frequencies. This affect was observed in this experiment with a guitar string, a motor, and a cell phone. The vibration of these systems can be measured with an accelerometer. The accelerometer converts mechanical acceleration

Innovative Energy-Based Probabilistic Approach for Semi-Active Vibration Control in Wind Turbines Aly Mousaad Aly Overview: The goal of this project is to enable the building of smart, resilient, and sustainable energy infrastructure, by advancing fundamental knowledge in the science of aerodynamics and control theory. The main objective is to test the following hypotheses: (i) semi-active control of structures can be carried out analytically, (ii) a proposed innovative control theory is applicable
INVESTIGATION ON TURNING PARAMETERS ON MACHINING TIME AND VIBRATION OF CARBON FIBER REINFORCED LAMINATES ABSTRACT: This work proposes the investigation of machining time and vibration characteristics of machining differently oriented unidirectional Carbon Fiber Reinforced Polymer (CFRP). The carbon fibers are oriented at 0, 45, 90 degrees during stacking process of laminate. The turning experiments are carried out in Siemens-CNC Lathe to investigate best operating conditions. There are 9 experiments
Do you suffer from nomophobia or cell phone vibration syndrome? In other words do you fear being without your phone or missing a text? If so you are not alone. “46% of smartphone owners say their smartphone is something they couldn’t live without” (Anderson). Americans say that they are dependent on their phones because it is their access point to the Internet. This number keeps increasing because of technological advancements. According to Jacob Davidson in the article “Here’s How Many Internet
Natural disasters have become very critical due to several reasons like global warming. Wireless sensor networks are used for detecting the natural events by measuring the temperature, air pressure, vibration, etc. and generate alarms. WSNs can measure the agitation of buildings, CO2 levels, and weather monitoring, etc. (Yawut & Kilaso, 2011). WSN that utilized Zigbee/IEEE802.15.4 is utilized as a weather monitoring network. It sends the information about the weather and generates hazard alarms.
