Sparse linear algebra is an important kernel in many different applications. Among various sparse general matrix-matrix multiplication (SpGEMM) algorithms, Gustavson’s column-wise SpGEMM has good locality when reading input matrix and can be easily parallelized by distributing the computation of columns output to processors. However, accumulation (SPA) step SpGEMM, which merges partial sums fro...

When visual sensor networks (VSNs) enter daily life in society, they not only bring great convenience but also cause people to worry about privacy. Traditional image encryption often displays the effect of snowflake encrypted images playing a part privacy protection, usability directly browsing taken by nodes VSNs is sacrificed. Recently, thumbnail-preserving (TPE) has been proposed balance and...

—Recently the developments of Ubiquitous Computing and Augmented Reality technologies have made many changes on the existing applications. However, the contents used in the applications have been not revised conceptually. Thus, an expansive representation of the contents is required to adapt resources to new computing environments, and to reflect new emerging features such as realism, mobility ...

The increasing computing demands of autonomous driving applications have driven the adoption multicore processors in real-time systems, which turn renders energy optimizations critical for reducing battery capacity and vehicle weight. A typical optimization method targeting traditional systems finds a speed under static deadline, resulting conservative savings that are unable to exploit dynamic...

The comparative in vitro activities of two new oxazolidinone antimicrobial agents, U-100592 and U-100766, against 180 isolates of enterococci representing several resistance profiles were examined by using an agar dilution technique. The two oxazolidinones inhibited all isolates, including strains resistant to vancomycin, ampicillin, and minocycline, at concentrations between 1 and 4 micrograms...

Modern vehicles can be thought of as complex distributed embedded systems that run a variety automotive applications with real-time constraints. Recent advances in the industry towards greater autonomy are driving to increasingly connected various external (e.g., roadside beacons, other vehicles), which makes emerging highly vulnerable cyber-attacks. Additionally, increased complexity and in-ve...
