Parallel sparse and banded matrix – multiple vectors multiplication Cincioğlu, Meftun; Manguoğlu, Murat; Department of Computer Engineering (2014) In this thesis, performance of two important primitives, namely sparse and banded matrix – multiple vectors multiplication are studied. Sparse matrix – multiple vectors multiplication (SpMM) is one of the basic and most time consuming operations in many problems in science and engineering. Hence, any improvement in the performance of SpMM operations has a great impact on the wide spectrum of problems. One of the objectives of this thesis is to improve the performance of parallel SpMM operation by reducing i...
A parametric study on three dimensional modeling of parallel tunnel interactions Karademir, Salahaddin Miraç; Erol, Orhan; Department of Civil Engineering (2010) A parametric study is performed to investigate the parallel tunnel interaction. Three dimensional finite element analyses were performed to determine the effects of soil stiffness, pillar width and advancement level of the second tunnel on the behaviour of displacement, bending moment and shear force of the previously constructed tunnel. In the analysis PLAXIS 3D Tunnel geotechnical finite element package was used. This program allows the user to define the actual construction stages of a NATM tunnel constr...
The Multi-objective path placement optimization of parallel kinematic machines Küçük, Ali; Söylemez, Eres; Department of Mechanical Engineering (2013) The aim of this study is to obtain optimal position and orientation of a trajectory frame with respect to the fixed frame of the manipulator. The work path which is given in the trajectory frame is also constrained in the workspace of the 3 – PRS parallel kinematic machine. In the analysis, forward and inverse kinematics solutions are derived as well as the inverse dynamics model using Lagrange’s Method. Several algorithms governing the motion of the manipulator are developed. Moreover, optimization goals a...
Progresses in parallel random number generators Kaşıkara Tenekecioğlu, Gülin; Kiper, Ayşe; Department of Computer Engineering (2005) Monte Carlo simulations are embarrassingly parallel in nature, so having a parallel and efficient random number generator becomes crucial. To have a parallel generator with uncorrelated processors, parallelization methods are implemented together with a binary tree mapping. Although, this method has considerable advantages, because of the constraints arising from the binary tree structure, a situation defined as problem of falling off the tree occurs. In this thesis, a new spawning method that is based on b...
Robust conditional value–at–risk under parallelpipe uncertainty: an application to portfolio optimization Kara, Güray; Weber, Gerhard Wilhelm; Department of Financial Mathematics (2016) In markets with high uncertainties, the trade–off between maximizing expected return and minimizing the risk is one of the main challenges in modeling and decision making. Since investors mostly shape their invested amounts towards certain assets and their risk version level according to their returns; scientists and practitioners has done studies on this subject since the beginning of the stock markets’ establishment. Developments and inventions in the mathematical optimization provide a wide range of solu...
