Simulation of hydrothermal vents in the Izena Cauldron,Mid Okinawa trough,Japan and other Pacific locations

Simulation results of Jade hydrothermal vent in Okinawa trough, Japan and Dante hydrothermal vent in Endeavour ridge in the north east Pacific are presented using an improved version of MOHTV model. The results are presented along with some limited field comparisons. A limited study on the sensitivity of model results to key model parameters is also presented. The model used is capable of simulating the hydrodynamics, thermodynamics, and mineral formations in underwater hydrothermal vents. The transport and spread of the plume fluid and minerals formed are simulated in three stages: plume dynamics stage that is momentum and buoyancy driven; transition to far field conditions as a gravity current; and far field conditions where the mineral particles move according to advection diffusion governed by the ambient currents and mineral particle settling velocities that eventually lead to their bed deposition. Thermodynamics include the changes in plume temperature and its related properties such as the vent fluid density. Physico-chemical processes are the chemical reactions that occur in the plume due to the hot vent fluid mixing with cold ambient water. Chemical reactions form new compounds (mostly minerals), which change the plume properties and therefore its behavior. Model simulates the formation of minerals namely FeS, FeS₂, ZnS, CuFeS₂, CuS, PbS, CaSO₄, BaSO₄, and Particulate Manganese – PMn. This improved version of MOHTV considers a user defined particles size distribution, the bathymetry of the ocean bottom, and can be used to run long-term simulations. The model results compare reasonably well with the field data. The parametric analyses show, which input and/or ambient conditions most affect the distribution of particles.

2004 award winners: Distinguished Contributions to the Public Interest.

Presents the citations, biographies, and selected papers of the 2004 recipients of the APA Awards for Distinguished Contributions to Psychology in the Public Interest (Dante Cicchetti [Award for Distinguished Senior Career Contributions to Psychology in the Public Interest] and Susan Limber [Award for Distinguished Early Career Contributions to Psychology in the Public Interest]) and the APA Award for Distinguished Contributions to Research in Public Policy (Thomas J. Coates). The Awards for Distinguished Contributions to Psychology in the Public Interest recognize persons who have advanced psychology as a science and/or profession by a single extraordinary achievement or a lifetime of outstanding contributions in the public interest. Two awards are given: the first to a psychologist who has made a significant contribution to the public interest in the early stages of his or her career, and the second to a senior psychologist. The Board for the Advancement of Psychology in the Public Interest confers the Award for Distinguished Contributions to Research in Public Policy on a psychologist who has made a distinguished empirical and/or theoretical contribution to research in public policy, either through a single extraordinary achievement or a lifetime of work. This contribution might include research leading others to view specific national policies differently, research demonstrating the importance of the application of psychological methods and theory to public policy, or research clarifying the ways scientific knowledge of human behavior informs public policy.

Dante技术：音频传输技术发展的趋势（李薇约）

随着科学技术的快速发展,千兆以太网的普及和爆炸式增长,音频技术的创新和普及也步入了崭新的阶段。录音师们总是希望通道数量增多、传输速度加快、调音台性能更多、音频接口归一化、系统集成性能越来越高,并逐渐不能满足传统物理性的模拟化电缆信号传输或者数字化的电缆以及光缆信号传输,数字化二进制码的网络化信号传输进入了人们的视线。现对音频信号的传输与分配的三个阶段进行分析比较,以Dante技术为例,浅析音频信号传输与分配的网络化发展趋势。     

Socks5服务器恶意会话攻击容忍技术研究

通过代理服务器访问Internet的用户越来越多,针对代理的安全事件也层出不穷,由此使得安全性成为了代理服务器研究的关键问题之一。本文从代理会话流程的角度,对Socks5代理服务器应对恶意会话能力薄弱的问题进行分析。针对这一问题,提出一种会话进度监督、资源延时分配的恶意会话攻击容忍方法,并将该方法应用于Dante代理服务器软件。实验结果表明,本文提出的改进方案可以明显降低恶意会话攻击对Socks5代理服务器的影响,增强了服务器的恶意会话攻击容忍能力。
