• The effects of ultrasound parameters and microbubble concentration on acoustic particle palpation 

  Saharkhiz, Niloufar; Körük, Hasan; Choi, James J. (Acoustical Society of America, 2018-08-17)

  The elasticity of tissue—an indicator of disease progression—can be imaged by ultrasound elasticity imaging technologies. An acoustic particle palpation (APP) has recently been developed—the use of ultrasonically driven ...

• Detection of air leakage into vacuum packages using acoustic measurements and estimation of defect size 

  Körük, Hasan; Şanlıtürk, Kenan Yüce (Elsevier Ltd., 2019-01-01)

  Air leakages in food and ingredient packages which are sealed in vacuum environments may cause a marked deterioration of the product, leading to a loss of functionality. Manufacturers of such products have very stringent ...

• Lessons from the rector of the first fully flipped learning university 

  Şahin, Muhammed (FLR The Flipped Learning 3.0 Magazine, 2018-05-08)

  Sahin: MEF Educational Institutions was founded in the 1970s by İbrahim Arıkan, an educator and businessman. In 1996, he founded MEF national and international K-12 schools in Istanbul and Izmir. In 2013, he founded MEF ...

• Investigation of the vibro-acoustic behaviors of luffa bio composites and assessment of their use for practical applications 

  Genç, Garip; Körük, Hasan (The International Institute of Acoustics and Vibration, 2016-07-10)

  New materials as alternatives to petroleum-based composite materials are needed due to adverse effects of chemical materials on nature. On the other hand, there is a need to characterize and evaluate new alternative materials ...

• On the difficulties in manufacturing of luffa fibers reinforced bio-composites and variations in their dynamic properties 

  Genç, Garip; Körük, Hasan (Institute of Noise Control Engineering, 2016)

  Defects in raw bio materials such as luffa plant effect the characteristics of the composites of these materials. These defects results in structural differences and large scattering mechanical properties such as density, ...

• Application of ultrasonic vibrations for minimization of the accumulation of limescale in steam irons 

  Körük, Hasan; Serenli, Muzaffer; Şanlıtürk, Kenan Yüce (Elsevier Ltd., 2018-06-01)

  The accumulation of limescale in steam irons can significantly reduce the ironing efficiency. It is this problem that inspired us to introduce ultrasonic vibrations to irons in order to minimize limescale accumulation. ...

• Identification of the Dynamic Characteristics of Luffa Fiber Reinforced Bio-Composite Plates 

  Genç, Garip; Körük, Hasan (NC State University, 2017-06-07)

  Luffa cylindrica plant fiber is a new biodegradable engineering material. However, the dynamic behaviors of these new green materials or their composites should be explored to consider them for practical applications. The ...

• Identification of crack noises in household refrigerators 

  Körük, Hasan; Arısoy, Ahmet (Elsevier Ltd., 2015-03-01)

  The crack noises propagating from a refrigerator disturb residents in a household; however, the reasons behind the mechanisms of such noises have not been identified yet. In this study, the crack noises in modern household ...

• Characterization of Viscoelastic Materials Using Free-Layered and Sandwiched Samples: Assessment and Recommendations 

  Özer, Mehmet Sait; Körük, Hasan; Şanlıtürk, Kenan Yüce (Polish Physical Society, 2015-04-01)

  Viscoelastic materials are widely used in many applications in practice. However, determination of the elastic and damping properties of these materials is quite difficult in the sense that the identified results may contain ...

• A new triangular composite shell element with damping capability 

  Şanlıtürk, Kenan Yüce; Körük, Hasan (Elsevier Ltd., 2014-08-07)

  This paper presents a new triangular composite shell element with damping capability. Formulation of the composite triangular shell element is based on stacking individual homogeneous triangular shell ele- ments on top of ...
