PURPOSE Speech language pathologists recommend graphic symbols for AAC users to facilitate communication, including labelling and expressing emotions. The purpose of the current study was to describe and compare how 5- to 6-year-old Afrikaans- and Sepedi-speaking children identify and choose graphic symbols to depict four basic emotions, specifically happy, sad, afraid, and angry. METHOD Nine...

The Smith-Waterman (SW) algorithm has been widely utilized for searching biological sequence databases in bioinformatics. Recently, several works have adopted the graphic card with Graphic Processing Units (GPUs) and their associated CUDA model to enhance the performance of SW computations. However, these works mainly focused on the protein database search by using the intertask parallelization...

Video-plus-depth is an image sequence of synchronized color and depth images. As importance of video-plus-depth increases as an essential part of the next-generation multimedia applications, it is crucial to estimate accurate depth information from a real scene and to find a practical framework to use the immersive video in industry. In this chapter, we introduce a hybrid camera system composed...

Texture mapping has traditionally added visual realism to computer graphics images. Modern graphic boards reserve more space for image textures that are mapped in real time on 3D meshes. Outside the graphic accelerators texture images are stored in popular compressed formats that are not designed to meet real-time texture decompression requirements. In the paper we forward an alternative techni...

We develop a new one-way wave prestack depth migration method called Fourier integration (FI) method which uses the exact extrapolation operator and the exact velocity model without any approximations or assumptions. The work is performed on a CUDA (Compute Unified Device Architecture) based Graphic Processing Unit (GPU). Compared to the traditional one way wave method, the GPU version FI metho...

Based on the arrangement of historical data source and artistic value graphic elements in traditional Chinese culture, article uses comparative research methods to analyze art form originating from civilization according chronicle. For façade, classification method elements, main features are sorted out, pattern characteristics, scene meaning development mainly deduced. From perspective semioti...
