Yayın Development of acoustic and thermal insulation materials from pantyhose waste(Trans Tech Publications Ltd, 2023-03-31) Küçükali Öztürk, Merve; Sezgin, Hande; Yalçın Enis, İpek; Dolu, CemPopulation growth, urbanization, industrialization, developing technology, increasing welfare level and changing consumption habits cause solid wastes to increase day by day. There are also sub-waste groups that have not yet been fully recognized among the solid waste groups in which textile wastes have a large share. One of them is pantyhose, which has been indispensable for modern life since the day it was presented to the consumer. These socks, which are made of polyamide and elastane fibers that are easily punctured, run and become unusable when worn once or several times, are generally thrown away after use. These pantyhose wastes, which are not biodegradable due to their raw materials, also pose an environmental risk. Within the scope of the study, thermal and sound insulation properties of carded and needle-punched pantyhose wastes are investigated. The results show that the thermal and acoustic properties of the developed material are at a sufficient level, and it has ensured that polyamide wastes, which have superior properties among thermoplastic polymers and have high economic value, are brought back into the economy.Yayın A source seeking algorithm with application to a quadcopter model(Nova Science Publishers, 2019-01-01) Dinçmen, ErkinA novel extremum seeking (ES) algorithm is developed and its performance is tested on a quadcopter type unmanned aerial vehicle (UAV) model. The motivation of the paper is to develop an ES algorithm that results no oscillations in the system behaviour during the search process. Via the proposed algorithm, the quadcopter searches autonomously a signal source/target without knowing its location a priory. The controller does not use any position or GPS measurements. The presented control algorithm is composed of two phases: In the first phase, the search algorithm determines required translational acceleration values of the UAV. In the second phase, a PID-type controller is utilized to control roll and pitch angles of the UAV to maintain computed acceleration values via the search algorithm. Performance of the controller is evaluated via simulation studies.Yayın Yayın Bubble dynamics and shock waves(Springer Berlin Heidelberg, 2013-01-01) Delale, Can FuatThis volume of the Shock Wave Science and Technology Reference Library is concerned with the interplay between bubble dynamics and shock waves. It is divided into four parts containing twelve chapters written by eminent scientists. Topics discussed include shock wave emission by laser generated bubbles (W Lauterborn, A Vogel), pulsating bubbles near boundaries (DM Leppinen, QX Wang, JR Blake), interaction of shock waves with bubble clouds (CD Ohl, SW Ohl), shock propagation in polydispersed bubbly liquids by model equations (K Ando, T Colonius, CE Brennen. T Yano, T Kanagawa, M Watanabe, S Fujikawa) and by DNS (G Tryggvason, S Dabiri), shocks in cavitating flows (NA Adams, SJ Schmidt, CF Delale, GH Schnerr, S Pasinlioglu) together with applications involving encapsulated bubble dynamics in imaging (AA Doinikov, A Novell, JM Escoffre, A Bouakaz), shock wave lithotripsy (P Zhong), sterilization of ships’ ballast water (A Abe, H Mimura) and bubbly flow model of volcano eruptions ((VK Kedrinskii, K Takayama). The book offers a timely reference for graduate students as well as professional scientists and engineers interested in the interaction of shock waves with bubbles and their propagation properties in bubbly liquids with applications in medical and earth sciences.
