The State-of-the-Art Numerical Tools for Modeling Landslide Tsunamis: A Short Review

Heidarzadeh, Mohammad
Krastel, Sebastian
Yalçıner, Ahmet Cevdet
We present a short review of the state-of-the-art numerical tools that have been used for modeling landslide-generated waves. A comparative study is conducted on the physical properties of earthquake- and landslide-generated waves suggesting that both dispersion and nonlinearity effects may be neglected for the former waves whereas they may be considered for the latter ones. We introduce landslide tsunami models and group them into three classes: (1) models treating the moving mass as a fluid, (2) models estimating the initial water surface, and (3) models fed by the transient seafloor deformation. Selection of a particular model from the list of models introduced here depends on: (1) the dimensions of the source, (2) the available computing capacities, (3) availability of fine bathymetric grid, and (4) the purposes of the modeling.


An Upper Bound for Limited Rate Feedback MIMO Capacity
Güvensen, Gökhan Muzaffer; Yılmaz, Ali Özgür (Institute of Electrical and Electronics Engineers (IEEE), 2009-06-01)
We develop a technique to upper bound the point-to-point MIMO limited rate feedback (LRF) capacity under a wide class of vector quantization schemes. The upper bound turns out to be tight and can also be used to obtain an absolute upper bound by using a bounding distribution for Grassmannian beamforming. The bounding technique can be applied to other problems requiring the exact evaluation of the expected value of matrix determinant.
A shape deformation algorithm for constrained multidimensional scaling
Sahillioğlu, Yusuf (2015-12-01)
We present a new Euclidean embedding technique based on volumetric shape registration. Extrinsic representation of the intrinsic geometry of a shape is preferable in various computer graphics applications as it poses only a small degrees of freedom to deal with during processing. A popular Euclidean embedding approach to achieve such a representation is multidimensional scaling (MDS), which, however, distorts the original geometric details drastically. Our method introduces a constraint on the original MDS ...
The Stabilization Controller Design for a Tripod Type Parallel Manipulator Used for Active Suspension of a Delicate Device
Atesoglu, Oezguer; Özgören, Mustafa Kemal (2008-09-05)
This paper focuses on the nonlinear modeling of a tripod type parallel manipulator and the stabilization controller design for base disturbance attenuation. The active tripod is designed to isolate a delicate device, carried by a host vehicle, from the disturbing vibrations coming from the chassis of this host vehicle. For that purpose, a controller is designed and the tripod is used for vibration attenuation as an active suspension system. A detailed simulation model including the nonlinear model of the tr...
A Comparative Evaluation of Two Computer SupportedCollaborative Work Systems for Supporting Collaborative BusinessProcess Modeling Activities
Fındık Coşkunçay, Duygu; Çakır, Murat Perit (2018-10-01)
In this study, a comparative evaluation of different Computer-Supported Collaborative Work CSCW environments was conducted to reveal their constraints and affordances for supporting synchronous collaborative business process modeling cBPM activities online. For this purpose, two case studies were carried out with two CSCW systems that differ in terms of their interaction design features for supporting joint work. The dual-eye tracking method was employed to monitor how the participants focused their attenti...

Three-dimensional condensed asymmetrical node, variable grid, transmission-line matrix (TLM) method has been used in analyzing several millimeter waveguides on anisotropic substrates. The dispersion characteristics of image guides together with field and energy confinement properties at millimeter-wave frequencies have been investigated. Edge coupled microstrip line on a uniaxial substrate is analyzed for the even and odd mode dispersion characteristics. Finally the same analysis is repeated for bilateral f...
