A domain specific language for facilitating automatic parallelization and placement of SDR patterns into heterogeneous computing architectures by Mohapi, Lerato Jerfree

“…Moreover, the following hypothesis was validated, namely: "It is possible to design a DSL to facilitate the development of SDR applications and their deployment on HCAs without significant degradation of software performance, and with possible improvement in the automatically emitted low-level source code quality.". It was validated by; 1) Defining the OptiSDR attributes such as parallel DSP patterns and dataflow MoCs; 2) Providing parameterizable SDR modules with automatic parallelization and optimization for performance and accuracy; and 3) Presenting a set of intuitive validation constructs for accuracy testing using root-mean square error, and functional verification of DSP using two-dimensional graphics plotting for radar and real-time spectral analysis plots.…”

Genome-wide reconstruction of the metabolic network of Phaeodactylum tricornutum by Sharaf, Hazem

“…Such a network serves as powerful predictive tool for the state of metabolism by applying flux balance analysis (FBA) which is based on a mathematical linear optimization approach. The advantages of FBA are to derive insights about the metabolic phenotype of an organism and to direct metabolic engineering for further capabilities. …”
