Phoebus: A system for high throughput data movement

Phoebus is an infrastructure for improving end-to-end throughput in high-bandwidth, long-distance networks by using a “session layer” protocol and “gateways” in the network. Phoebus has the ability to dynamically allocate network resources and to use segment-specific transport protocols between gateways, as well as to apply other performance-improving techniques on behalf of the user. We have developed interfaces to Phoebus to allow its use in various real applications and data movement services. This paper extends our earlier work with tests of Phoebus-enabled applications on both real-world networks as well as over configurable network testbeds that allow us to modify latency and loss rates. We demonstrate that Phoebus improves the performance of bulk data transfer in a variety of network configurations and conditions.     

香荚兰豆专题系列之四——香荚兰豆初级与深度加工及其应用

几百年来,香荚兰豆(Vanilla fragrans And planifold&Vanilla Tahitensis),又称香草兰干豆荚、香子兰干豆荚,俗称香草,是当今世界上最为风行的香味物质。她具有十分诱人的香气,并以和谐、优雅、温馨、丰满的香韵而闻名香精香料领域,被誉为“食品香料皇后”。因此,作为一个香荚兰豆生产商、供应商及使用客户,充分了解香荚兰豆生产的全过程及最终添香于高档香烟和食品的加工消费过程是至关重要的。本专题就香荚兰豆初级加工与深度加工及其应用进行了实际工作性的阐述。     

基于Struts框架的Web报表展示的设计与实现

Struts是目前非常流行的基于MVC的Java Web框架.Web报表的开发,各个企业也提出了不同的解决方案.在Web报表上有效展示大量数据的问题,仍是值得关注的问题.为解决在Web页面上大量数据的展示问题,本文设计一种基于Struts框架的Web页面上数据展示的方案,该方案从优化表格元素和处理特定图像元素入手,有效提高了展示效率及效果.本文首先介绍了Struts的工作原理和结构,就Web报表展示中Bean的优化设计进行讨论,最后在Struts框架上对报表的Web展示进行实现.     

Genetic and environmental effects on chemical composition related to sensory traits in common beans (Phaseolus vulgaris L.)

The chemical composition determines plant-derived foods’ sensory traits; genetic and environmental effects and their interactions determine chemical composition. Understanding the importance of each factor should help characterise foodstuffs according to the variety and place of cultivation. We studied the effects of variety (five landraces + two checks) and environment (five locations and two years) on some molecules important for beans’ (Phaseolus vulgaris L.) sensory value. The greatest location effects were on protein and starch content and variety effects were due to combinations of traits (mainly sucrose, protein, and malic acid). The variety × location interactions detected in protein, sucrose, citric acid, and malic acid were difficult to associate to the gastronomic success of a particular variety cultivated at a particular location. Our results showed that protected designation of origin (PDO) in beans could be delimited on the basis of chemical composition, derived from the particular environmental characteristics of a region and the genetic characteristics of the varieties admitted.     

豆渣可食用包装纸的研制

豆渣含有大量纤维素和钙,含有少量脂肪,具有较高的营养价值。为扩大豆渣的利用途径,提高大豆的经济价值,以鲜豆渣为原料,通过研究酶添加量、提取温度、时间、p H对豆渣中可溶性膳食纤维提取的影响,确定最佳条件。结果表明,当酶添加量0.5%、反应时间100 min、反应温度48℃、p H 4.3时提取率最高,为4.56%。将制得的可溶性膳食纤维与海藻酸钠、CMC和甘油按比例混合,以膜抗拉伸强度为指标,探究可溶性膳食纤维、甘油、CMC、海藻酸钠的添加量对豆渣可食用包装纸性能的影响。由正交实验可知当可溶性膳食纤维添加量为2.0%、海藻酸钠1.5%、CMC0.5%、甘油1.5 m L时制得的膜性能最佳,抗拉强度为7.42 MPa。     

生物处理组合装置在高浓度豆制品有机废水处理中的应用

针对豆制品废水腐蚀性强、有机污染物浓度高、氨氮浓度高、悬浮物浓度高的特点,采用上流式厌氧污泥床和厌氧-好氧组合法处理豆制品废水,取得了较好效果,最终出水可达到上海市地方标准《污水排入城镇下水道水质标准》的要求。采用厌氧法处理时产生沼气。对沼气的利用,既可减少对环境的影响,还可获得可观的经济效益。
