Acoustic emission evaluation of concrete culverts Birgul, R; Al-shammari, FMW; Yaman, İsmail Özgür; Aktan, MH (Informa UK Limited, 2004-10-01) An experimental investigation was conducted to address the durability aspect of steel-reinforced concrete (RC) culverts using an accelerated aging environment. Analysis of the experimental data was built on the acoustic emission (AE) activity. AE methodologies were used to compare the behaviors of RC culverts after an aging process using a rate-process analysis. In the rate-process analysis, probability density functions (PDF) of AE activity were obtained from the experimental data to indicate the damage st...
Acoustic tracking of ship wakes Önür, Çağla; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2013) Theories about ship wake structure, bubble dynamics, acoustic propagation through bubble clouds, backscattering and target strength of bubble clouds have been investigated and related Matlab simulations have been carried on. Research has been carried on algorithms for ship wake acoustic detection and tracking. Particle filter method has been simulated with Matlab for target tracking using wake echo measurements. Simulation results are promising.
Acoustical analysis of exhaust mufflers for earth-moving machinery Olğar, Tarık; Çalışkan, Mehmet; Department of Mechanical Engineering (2009) This study concerns with acoustical analysis of exhaust mufflers for earth-moving machinery. The study arises from the fact that there is a need for further noise reduction emitted by earth-moving machinery produced by Hidromek Inc. in order to be on the safe side of the limits stated in European Noise Directive 2000/14/EC. The acoustical performance of the muffler is investigated both experimental and numerical means. A three-dimensional finite element method is performed to calculate the transmission loss...
ACOUSTIC SURFACE PERCEPTION FOR IMPROVED MOBILITY OF LEGGED ROBOTS Ozkul, Mine Cuneyitoglu; Saranlı, Afşar; Yazıcıoğlu, Yiğit (2012-08-15) A dynamically dexterous legged robot has the distinct property that the legs are continuously interacting with the environment. During walking and running, this interaction generates acoustic signals that carry considerable information about the surface being traversed, state of the robot legs and joint motors as well as the stability of the locomotion. Extracting a particular piece of information from this convolved acoustic signal however is an interesting and challenging area of research which we believe...
ACOUSTIC LEVITATON OF AIR-FILLED SHELL-TYPE MATERIALS Kandemir, Mehmet Hakan; Çalışkan, Mehmet (2015-07-16) Standing wave acoustic levitation technique utilizes a standing wave formed between a sound source and a reflector. Nodes of the standing wave act as linear springs to attract the particles towards the pressure nodes, thus particles can be suspended or levitated in air. Theoretically, any material in any state can be levitated using this technique. However, in practice, the attempts to levitate materials are limited to those mostly of regular shape. A common type is air-filled closed form shell structures. ...
