Effect of achilles tendon vibration at adapting to different sensory conditions
Carlak, Renan Arda; Gürses, Senih; Department of Engineering Sciences (2019)
The aim of the study is to investigate the effect of Achilles tendon vibration (ATV) on postural sway behavior and backward body tilt (fall) response at adapting to different sensory conditions. The effect of anticipation ...
Proposed minimum restoring force equations for seismic isolated structures
Görgülü, Ali Günalp; Dicleli, Murat; Department of Engineering Sciences (2019)
In this research study, a new set of restoring force equations are proposed for seismic isolated structures subjected to far fault ground motions (FFGM) and near fault ground motions (NFGM). For this purpose, 110 FFGM and ...
An Investigation of the increase in variability of standard penetration test results for gravelly soils
Pehlivan, Alper; Yılmaz, Mustafa Tolga; Department of Engineering Sciences (2019)
Variability in the results of standard penetration tests (SPT) due to nonuniformity of particle size distribution in soil layers is a known issue in geotechnical applications. Such phenomenon may result in artificial incre...
Development of computational fluid dynamics (CFD) based topology optimization codes in OpenFOAM
Şenol, Niyazi; Eraslan, Ahmet Nedim; Akay, Hasan Umur; Department of Engineering Sciences (2018)
Optimization has been commonly used by engineers in industry to design and fabricate products efficiently, since it has a great impact on the performance. The recent decades have witnessed an important amount of work in de...
Negative bending of strain hardening curved beam in the elastoplastic states of stress
Çakır, Gamze; Eraslan, Ahmet Nedim; Department of Engineering Sciences (2018)

Effect of the vestibular system on search and fall behaviour of human postural sway
Cengiz, Berat Can; Gürses, Senih; Department of Engineering Sciences (2017)
In a person's daily life, upright stance is a very essential postural position for using hands, locomotion, communication, etc. These motivations probably help a baby to solve this complex motor task faster. A healthy indi...
Postural responses of patients with bilateral vestibular loss and healthy subjects to sinusoidal tilts
İmir, Mehmet; Gürses, Senih; Department of Engineering Sciences (2017)
Posture control to maintain the stability of upright posture is a very complex task. It requires sensorimotor integration of all sense organs. If one of these organs loses its functionality, the person may have difficultie...
Elastic analysis of orthotropic cylinders under different boundary conditions
Farukoğlu, Ömer Can; Eraslan, Ahmet Nedim; Department of Engineering Sciences (2016)

A Semi-empirical method for estimation of maximum seismic shear strain in imperforated ground excited by vertically propagating shear waves
Dehghanian, Kaveh; Yılmaz, Mustafa Tolga; Department of Engineering Sciences (2016)
Seismic design of underground structures requires calculation of the deformation in surrounding geological formations. The seismic hazard on a site is usually expressed as a function of amplitude parameters of free-field m...
Classification of bridge damages and costs for optimal maintenance planing based on markov decision process
Aslzad, Reza; Akgül, Ferhat; Department of Engineering Sciences (2016)
Serviceability of a bridge is gradually reduced over time due to loads they carry andthe environmental effects. The effect of deterioration on bridges begin to appear when the bridges start aging and the materials are subj...
