The effects of the material density and dimensions of the landslide on the generated tsunamis

İnsel, Işıl
In this thesis study; mechanism and modeling of tsunamis generated by landslides are investigated. Landslide parameters affecting the surface wave characterisics are studied. In order to understand occurance of this kind of tsunamis, among many historical tsunamis, the ones that are triggered by landslides are detected and studied. The generation of the landslide generated tsunamis are modeled using TWO-LAYER model, which solves nonlinear long wave equations simultaneously within two interfacing layers with necessary boundary conditions at the sea bed, interface and water surface. The model is applied to one of the possible landslides at offshore Yalova in the Sea of Marmara. Two of the controlling parameters, which are the density and the thickness of the slid material, are analysed and a sensitivity analysis is performed to determine the level of their effects on the evolution and amplitude of the tsunami source. Furthermore, the propagation and coastal amplification of the landslide generated waves are investigated using the tsunami simulation and visualization code NAMI DANCE. The results are presented, compared and discussed.


Investigation of the significance of periodicity information in speaker identification
Gürsoy, Seçil; Çiloğlu, Tolga; Department of Electrical and Electronics Engineering (2008)
In this thesis; general feature selection methods and especially the use of periodicity and aperiodicity information in speaker verification task is searched. A software system is constructed to obtain periodicity and aperiodicity information from speech. Periodicity and aperiodicity information is obtained by using a 16 channel filterbank and analyzing channel outputs frame by frame according to the pitch of that frame. Pitch value of a frame is also found by using periodicity algorithms. Parzen window (ke...
The influence of strain history and strain gradient on confined concrete
Ersoy, Uğur; Üzümeri, S. Muvaffak; Tankut, A.Tuğrul (Canadian Science Publishing, 1987-6-1)
<jats:p> This paper outlines the results of tests performed to study the effect of strain gradient, strain history, and initial precracking on the efficiency of confinement in reinforced-concrete columns. To this end, five reinforced-concrete specimens with closely spaced ties have been tested under combined flexure and axial load.Two of the specimens were used as control specimens, subjected only to a strain gradient. The remaining three specimens were precracked using different loading schemes and then te...
Electromagnetic compatibility of electric power quality monitor according to EN 61326 standard
Yaman, Özgür; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007)
In this thesis; Electromagnetic Compatibility (EMC) of Electric Power Quality Monitor developed within the scope of National Power Quality Project has been investigated according to EN 61326 standard. Both immunity and emission tests have been carried out in EMC laboratories of ELDAS and ASELSAN for the device under test. Necessary counter measures such as using electromagnetic interference (EMI) filters and transient voltage suppressors, shielding the case of device with EMI protective materials have been ...

This thesis is revolved around three main inquiries. Firstly, the types of the three Libyan ceasefires, the Libyan Political Agreement (LPA), the Palermo Conference Conclusions and the Permanent Ceasefire of Libya, are examined. The examination was made with three sections structured by Malin Åkebo, (i) initiation, (ii) form and content and (iii) implementation and unfolding of the process. Then, how the ceasefires have influenced the peace processes of 2015, 2018, and 2020 and how the peace processes have ...
A switch mode power supply for producing half wave sine output
Kaya, İbrahim; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2008)
In this thesis; analysis, design and implementation of a DC-DC converter with active clamp forward topology is presented. The main objective of this thesis is generating a rectified sinusoidal voltage at the output of the converter. This is accomplished by changing the reference signal of the converter. The converter output is applied to an inverter circuit in order to obtain sinusoidal waveform. The zero crossing points of the converter is detected and the inverter drive signals are generated in order to o...
