BACKGROUND Oleaginous microalgae contain a high level of lipids, which can be extracted and converted to biofuel. The lipid-extracted residue can then be further utilized through anaerobic digestion to produce biogas. However, long-chain fatty acids (LCFAs) have been identified as the main inhibitory factor on microbial activity of anaerobic consortium. In(More)
—Most of the modern hard disk drives support Self-Monitoring, Analysis and Reporting Technology (SMART), which can monitor internal attributes of individual drives and predict impending drive failures by a thresholding method. As the prediction performance of the thresholding algorithm is disappointing, some researchers explored various statistical and(More)
—Backup technology based on data de-duplication has become a hot topic in nowadays. In order to get a better performance, traditional research is mainly focused on decreasing the disk access time. In this paper, we consider computing complexity problem in data de-duplication system, and try to improve system performance by reducing computing time. We put(More)
Hepatitis B virus (HBV) infection is a worldwide liver disease and nearly 25% of chronic HBV infections terminate in hepatocellular carcinoma (HCC). Currently, there is no effective therapy to inhibit HBV replication and to eliminate hepatoma cells, making it highly desired to develop novel therapies for these two stages of the HBV-caused detrimental(More)
Facing increasingly high failure rate of drives in data centers, reactive fault tolerance mechanisms alone can hardly guarantee high reliability. Therefore, some hard drive failure prediction models that can predict soon-to-fail drives in advance have been raised. But few researchers applied these models to distributed systems to improve the reliability.(More)
