加工硬质合金端铣刀刀槽时的工艺调整计算

硬质合金端铣刀刀体上的刀槽，通常将设计为槽底与铣刀轴线倾斜δ角，槽侧壁与铣刀轴线倾角为ω且偏移一个距离为ｅ，以使刀齿装夹在刀体上后获得端铣刀所需的几何角度。本文主要论述在万能铣床上铣削铣刀体上具有δ、ω、ｅ的刀槽时必要的工艺调整，利用矢量及座标转换推导了加工刀槽时必要的参数计算公式，为高效率、高质量地进行铣刀体刀槽的加工提供了一种精确可行的参数计算方法。

Fast neighborhood search for the single machine total weighted tardiness problem

Most successful heuristics for solving 1||∑w_jT_j are based on swap moves. We present an algorithm which improves the complexity of searching the swap neighborhood from O(n³) to O(n²). We show that this result also improves the complexity of the recently developed dynasearch heuristics.

从硬件和软件两方面详细阐述了基于CTV100平台的DPTV系统,并给出了总体设计框图和设计流程图。本项目采用意法半导体公司(ST)的CTV100解决方案,实现了对传统模拟电视信号的高效数字域处理,显著提高了电视画面的图像质量;并通过采用基于32bitCPU的OS20嵌入式操作系统,实现了多种传统模拟电视无法实现的功能。     

Distributed and Parallel Component Library

Software component library is the essential part of reuse-based software development. It is shown that making use of a single component library to store all kinds of components and from which components are searched is very inefficient. We construct multi-libraries to support software reuse and use PVM as development environments to imitate Iargescale computer, which is expected to fulfill distributed storage and parallel search of components efficiently and improve software reuse.     

Schedule-an expert-like system for machine scheduling

The construction of an expert-like system for machine scheduling called SCHEDULE is presented. Essential parts of SCHEDULE were developed by students in a laboratory course Operations Research on Microcomputers at the University of Karlsruhe, Germany. SCHEDULE consists of the components data base, knowledge base, inference engine, explanation facility, dialog component, and knowledge acquisition component. The knowledge base contains an algorithm base for solving different types of scheduling problems. To establish the rules of the knowledge base the well-known three-field classification of deterministic machine scheduling problems and the concept of the reduction digraph are exploited. Experiences gained during building and demonstrating SCHEDULE are reported.
