High-throughput signal processing for real-time analysis has been approached on dedicated hardware, for instance using field-programmable gate arrays (FPGAs) and graphics processor units (GPUs), see, e.g., [4,26]. These approaches can be advantageous in low-latency searches for signals at low...
In subject area: Computer Science A homogeneous system is a linear system of equations where all the variables have a coefficient of zero, and it always has a solution where all the variables are equal to zero, called the trivial solution. It may also have nontrivial solutions where not all...
Homogeneous coordinates are often used in computer graphics and computer vision applications especially for the representation of geometric transformations. The homogeneous coordinates enable us to represent translation, rotation, scaling and projection operations in a unique way and handle them properly. Toda...

storage" (C contiguous) conventions. The translation components are in the right column of the transformation matrix, i.e. M[:3, 3]. The transpose of the transformation matrices may have to be used to interface with other graphics systems, e.g. OpenGL's glMultMatrixd(). See also [16]...
Transverse elastic SH-waves excited by an oscillating power source in a solid medium also located close to the layer of different propagation velocity than the velocity of the vicinity are analyzed. Formulae for the spatial distribution of the wave field amplitude are derived and computer graphics ...
