Investigation of ground reaction force distribution beneath the foot in postural control
Akbarifar, Roshanak; Halıcı, Uğur; Gürses, Semih; Department of Biomedical Engineering (2014)
It has been reported that the ground reaction force (GRF) beneath the foot is distributed by the ratio of 1/3 in metatarsals and 2/3 in calcaneous. The main aim of this thesis is to check the ratio of GRF distribution with respect to front and hint regions of the foot and to understand the importance of the distribution ratio/rule in postural control. A mathematical model is designed and simulated using MATLAB® and Simulink® in which the foot is modeled as a deformable body, instead of being rigid, which ha...
Investigation of control of human balance-recovery reactions
Bilgin, Nurdan; Özgören, Mustafa Kemal; Department of Mechanical Engineering (2015)
In this study, a natural control law has been conjectured, which is assumed to be applied by the central nervous system of a human being in order to maintain the erect posture after being exposed to a suddenly occurring impulsive disturbance. The control law is conjectured as PD (proportional-derivative) control, because it has to be compatible with the physiological facts. The conjectured control law has been validated by comparing a set of experimental results with the corresponding set of simulation resu...
Analysis of mine accidents and financial consequences to gli mines
Özkan, Gökay; Güyagüler, Tevfik; Department of Mining Engineering (2007)
The expenditures resulting from work accidents is increasing every year. Among the other work accidents, mine accidents result important loss of time, money and lives. From the point of view of mine accidents, studies about cost of mine accidents need some contributions. In this thesis, cost of mine accidents to worker, employer, and total economy of country will be analysed in the light of data from Ministry of Labour, Social Security and Social Insurance Institution, and Türkiye Coal Enterprises. General ...
Immobilization of proteins on zeolite and zeo-type materials for biosensor applications based on conductometric biosensors and ion sensitive field effect transistors
Soy, Esin; Akata Kurç, Burcu; Özen, Can; Department of Micro and Nanotechnology (2011)
Over the last decade, immobilization of proteins onto inorganic materials is becoming more crucial to extend a deep understanding of interaction between proteins and nanoparticles. With understanding of the real interaction lying under the protein-nanoparticle relations, it is possible to organize the conformation and orientation of surface and framework species of nanoparticles to generate ideal surfaces for potential biotechnological applications. Due to their unique properties such as large clean surface...
Comparative study on ground vibrations prediction by statistical and neural networks approaches at Tunçbilek coal mine, panel byh
Akeil, Salah; Bilgin, Hasan Aydın; Department of Mining Engineering (2004)
In this thesis, ground vibrations induced by bench blasting from the Tunçbilek Coal Mine, Panel BYH, were measured to find out the site-specific attenuation and to assess the structural damage risk. A statistical approach is applied to the collected data, and from the data analysis an attenuation relationship is established to be used in predicting the peak particle velocity as well as to calculate the maximum allowable charge per delay. The values of frequencies are also analyzed to investigate the damage ...
