Reduction of dynamic earth loads on flexible cantilever retaining walls by deformable geofoam panels ERTUĞRUL, ÖZGÜR LÜTFİ; Trandafir, Aurelian C.; Özkan, M. Yener (2017-01-01) The potential application of geofoam in reducing the dynamic earth forces on flexible cantilever earth retaining walls was investigated through small-scale physical model tests. Tests were carried out using a state-of-the-art laminar container and a uniaxial shaking table. Deformable geofoam panels of low stiffness made from expanded polystyrene (EPS) and extruded polystyrene (XPS) geofoam were utilized as compressible inclusions in the present study. The dynamic stress-strain properties of these geomateria...
Reducing computational demand of multi-state constraint kalman filter in visual-inertial odometry applications Eyice, Kerem; Çiloğlu, Tolga; Department of Electrical and Electronics Engineering (2019) The aim of this study is to reduce the computational load required by Multi-State Constraint Kalman Filter in visual-inertial odometry applications while maintaining the accuracy of the localization solution. In order to accomplish this, a keyframe-based pose selection mechanism is proposed. The proposed method fuses visual measurements with inertial measurements in order to estimate the kinematics of the platform. The contribution of this study is to reduce computational demand of the filtering operations ...
Optimization of nickel, cobalt and lithium recovery processes from spent li-ion batteries Tekmanlı, Fırat; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2022-12-28) Since lithium-ion batteries are standard in electric vehicles and electrical devices and have the potential to be used widely in the future, it is essential to recycle end-of-life batteries. Waste lithium-ion batteries are harmful to the environment and human health and should be recycled also due to their critical metals. Lithium-ion batteries can be classified according to their cathode chemistry. In this thesis, the recycling of lithium-ion batteries with NMC-type (Nickel- Manganese-Cobalt) cathode chemi...
Enhancement of biodegradability by continuous ozonation in Acid Red-151 solutions and kinetic modeling Gokcen, F; Ozbelge, TA (Elsevier BV, 2005-11-15) In this work, continuous ozonation of aqueous Acid Red-151 was performed in a stirred tank reactor at neutral pH and 25 degrees C. The results show that ozonation is capable of a rapid conversion of the Acid Red-151 dye molecule to more biodegradable intermediates up to the ozonation time of 120 min at which the optimum BOD5/COD ratio is obtained. The peak BOD5/COD ratios were found to be in the range of 0.028-0.35 for the initial dye concentrations being in the range of 1000-100 mg/L, respectively.
Optimization of ride comfort for vehicles equipped with passive and active hydro-pneumatic suspensions Sağlam, Ferhat; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2016) The main objective of this study is the optimization of ride comfort performance of vehicles equipped with Hydro-Pneumatic (HP) suspension systems. In order to improve ride comfort performance together with handling behavior as a constraint, active-passive, and unconnected-interconnected HP suspension systems are included in the study. The basic HP suspension model is developed and validated by experiments. Various HP suspension systems of increasing complexity are modeled, and their dynamic characteristics...
