This study concentrates on transient multiphysical wave problems for simulating seismic waves. The presented models cover the
coupling between elastic wave equations in solid structures and acoustic wave equations in fluids. We focus especially on the
accuracy and efficiency of the numerical solution based on higher-order discretizations. The spatial discretization is performed
by the spectral element method. For time discretization we compare three different schemes. The efficiency of the higher-order
time discretization schemes depends on several factors which we discuss by presenting numerical experiments with the fourthorder
Runge-Kutta and the fourth-order Adams-Bashforth time-stepping. We generate a synthetic seismogram and demonstrate
its function by a numerical simulation.

Controllability method for acoustic scattering with spectral elements
Heikkola, Erkki; Mönkölä, Sanna; Pennanen, Anssi; Rossi, Tuomo (Elsevier, 2007)We formulate the Helmholtz equation as an exact controllability problem for the time-dependent wave equation. The problem is then discretized in time domain with central finite difference scheme and in space domain with ... -
Time-harmonic solution for acousto-elastic interaction with controllability and spectral elements
Mönkölä, Sanna (Elsevier, 2010)The classical way of solving the time-harmonic linear acousto-elastic wave problem is to discretize the equations with finite elements or finite differences. This approach leads to large-scale indefinite complex-valued ... -

Joint Spectral and Energy Efficiency Optimization for Downlink NOMA Networks
Khan, Wali Ullah; Jameel, Furqan; Ristaniemi, Tapani; Khan, Shafiullah; Sidhu, Guftaar Ahmad Sardar; Liu, Ju (Institute of Electrical and Electronics Engineers, 2020)Non-orthogonal multiple access (NOMA) holds the promise to be a key enabler of 5G communication. However, the existing design of NOMA systems must be optimized to achieve maximum rate while using minimum transmit power. ... -
