Real-time multi-media applications are increasingly mapped on modern embedded systems based on multiprocessor systems-on-chip （MPSoC）. Tasks of the applications need to be mapped on the MPSoC resources efficiently in order to satisity their performance constraints. Exploring all the possible mappings, i.e., tasks to resources combinations exhaustively may take days or weeks. Additionally, the exploration is performed at design-time, which cannot handle dynamism in applications and resources＇ status. A runtime mapping technique can cater for the dynamism but cannot guarantee for strict timing deadlines due to large computations involved at run-time. Thus, an approach performing feasible compute intensive exploration at design-time and using the explored results at run-time is required. This paper presents a solution in the same direction. Communicationaware design space exploration （CADSE） techniques have been proposed to explore different mapping options to be selected at run-time subject to desired performance and available MPSoC resources. Experiments show that the proposed techniques for exploration are faster over an exhaustive exploration and provides almost the same quality of results.

微藻生物质作为生物燃料的原料被广为研究。微藻生物量、脂质和碳水化合物含量的增加对于微藻生物燃料的商业化是十分重要的。在本研究中,同时向小球藻(Chlorella sorokiniana UTEX 1602)提供碳酸氢钠(0.25、0.5、1.0 和 2.0 g L-1)和富含 CO2 的氮气[CO2 浓度为 1%(v/v),流速 0.1 vvm],以提高小球藻的生物量和生物产物(脂质,蛋白质和碳水化合物)的产率以及碳利用效率。在NaHCO3浓度为1.0 g L-1时,微藻比生长速率可达到0.383 d-1,生物量生产率(291.0 mg L-1.d-1)和CO2固定率(547.16 mg L-1.d-1)达到最大。同时,中性脂质含量(20.60%),碳水化合物含量(21.21%)和蛋白质产率(0.949 g L-1)均高于不含碳酸氢盐的对照。结果还表明,增加NaHCO3浓度可以刺激中性脂质积累。在2.0 g L-1碳酸氢钠存在下,最高的中性脂质产率为30.44%。脂肪酸甲酯分析结果显示主要的脂肪酸是C16/C18,适合于生产生物柴油。研究表明,同时补充碳酸氢钠和CO2为微藻生产脂肪酸甲酯(FAME)更有效的碳源。
