以鼠标接口实现自动跟踪系统输入接口设计

坦克目标自动跟踪计算机系统是一个图像处理及瞄准线控制的专用系统,其需要许多开关、按钮等面板输入开关量信号,同时还要引入鼠标指示设备,以便于图形界面操作。提出了面板开关量输入接口设计方案采用鼠标接口,不用改动硬件,在不影响鼠标功能、不占用系统其他硬件资源的情况下,适用于PS/2协议和串口两种工作方式。操作方便、灵活,可靠性高。     

T300和JC2#纤维增强C/SiC复合材料力学性能对比

以聚碳硅烷(PCS)为先驱体,采用聚合物浸渍裂解法(PIP)分别制备得到T300碳纤维和JC2#碳纤维增强C/SiC复合材料。JC2#C/SiC复合材料具有优异的力学性能,抗弯强度和断裂韧性分别达到662MPa和19.5MPa.m1/2;T300 C/SiC复合材料表现出低强度、高脆性,其抗弯强度和断裂韧性不足前者的四分之一。T300 C/SiC复合材料低性能的根本原因在于T300纤维在PCS裂解过程中性能严重下降,复合材料中纤维与基体间存在强界面结合是另一个影响因素。

Multiple common due dates

Common due date problems have been extensively discussed in the scheduling literature. Initially, these problems discussed finding a common due date for a set of jobs on a single machine. These single machine problems were later extended to finding the common due date on a set of parallel machines. This paper further extends the single machine problem to finding multiple common due dates on a single machine. For a basic and important class of penalty functions, we show that this problem is comparable to the parallel machine problem. © 2001 John Wiley & Sons, Inc.

The selection allocation problem

The Selection Allocation Problem (SAP) is a single period decision problem which involves selecting profit‐maximizing (or cost‐minimizing) activities from various distinct groups, and determining the volume of those activities. The activities in each group are selected subject to the availability of that group's resource, which is provided by either pooling or blending raw inputs from several potential sources. Imbedded in the decision process is the additional task of determining how much raw input is to be allocated to each group to form the resource for that group. Instances of this problem can be found in many different areas, such as in tool selection for flexible manufacturing systems, facility location, and funding for social services. Our goal in this paper is to identify and exploit special structures in the (SAP) and use those structures to develop an efficient solution procedure. © 1999 John Wiley & Sons, Inc.
