注入氮离子的SiC涂层阻氢性能研究

利用离子束混合－离子注入（Ar^ ）和磁控溅射相结合的实验技术在HR－1不锈钢基体上制备了注入N^ 的SiC涂层，并用表面分析手段对所制备涂层的表面形貌，剖面形貌、相结构，表面成分，表面元素的化学态进行了分析，结果表明：制备的涂层结构致密，表面平整、膜层成分均匀；涂层与基体之间形成了一明显的过渡层，增强了涂层和基体之间的结合力，用二次离子质谱（SIMS）对充氘涂层的阻氢性能进行了定性分析，结果表明，涂层元素与氢形成稳定的化学键，抑制了氢的扩散和迁移，使得涂层具有一定的阻氢能力。     

用于IBM PC机与数字图象处理系统PERICOLOR 2000联机的并行接口设计

本文介绍一种采用并行接口将PERICOLOR 2000与IBM PC/XT或386联机的方法.通过这个并行接口,IBM PC/AT或386可成为PERICOLOR2000的宿主机,而PERICOLOR 2000则成为IBM PC/AT或386的一个图象工作站.IBM PC/AT或386可以控制PERICOLOR 2000的运行并能实现IBMPC/AT或386与PERICOLOR 2000之间的双向数据传输,从而大大提高了PERICOLOR 2000的使用效率.     

Defensive Disclosure of Patentable Inventions under Antitrust Enforcement

Why do large firms disclose patentable inventions defensively? We study IBM's disclosure and patenting activity and find that stronger antitrust enforcement and consent decrees limiting patent protection lead to more defensive disclosure. We extend our analysis to Xerox and show, using a differences-in-differences approach, a decline in patent propensity and an increase in patent scope in patent classes affected by the 1975 consent decree. We extend our analysis to include AT&;T, the other exceptionally large firm with defensive-disclosure activity, and show that their patenting propensity declined under increased antitrust enforcement relative to other firms in the industry. Overall, we show how these firms used defensive disclosure as a strategy to balance the benefits of patenting with the costs of uncertain antitrust enforcement. Our results are especially relevant in light of the defensive patent strategies many firms employ to preempt and cope with patent litigation.

An improvement for the McGill University Random Number Package

This paper documents and provides code for two new entry points which increase the flexibility of the McGill University Random Number Package. With these additions the user can access internal locations containing the pseudo-random integers that control the random sequences produced by the generator. A detailed example of the use of the new entry points is provided. Finally, some comments about the documentation of random number generators are made.

Turbulent flow over thin rectangular riblets

The effect of longitudinal thin rectangular riblets aligned with the flow direction on turbulent channel flow has been investigated using direct numerical simulation. The thin riblets have been modeled using the immersed boundary method (IBM) where the velocities at only one set of vertical nodes at the riblets positions are enforced to be zeros. Different spacings, ranging between 11 and 43 wall units, have been simulated aiming at getting the optimum spacing corresponding to the maximum drag reduction while keeping the height/spacing ratio at 0.5. Reynolds number based on the friction velocityuτ and the channel half depth δ is set to 150. The flow is driven by adjusted pressure gradient so that the mass flow rate is kept constant in all the simulations. This study shows similar trend of the drag ratio to that of the experiments at the different spacings. Also, this research provides an optimum spacing of around 17 wall units leading to maximum drag reduction as experimental data. Explanation of drag increasing/ decreasing mechanism is highlighted.
