浅析新形式下开设电子设计实验公共选修课

为适应高校实验教学改革的要求,我们面向全校开设了“电子设计实验”公共选修课,此举在全校同学中引起了强烈反响。作为实验教学的一种尝试。本文仅对在我校开设电子设计公共选修课的意义和实验方法等进行了探讨。     

读"面向21世纪电工电子系列课程教学内容和课程体系改革的研究与实践总结"后的联想

笔者主要阐述了在阅读电气电子教学学报第23卷第3期中登载的陈笃信教授等的文章后所产生的联想,其中包括：学校的中心任务如何保证,培养人才的目标如何落实,教材的编写如何配合三个部分。     

Data acquisition in the EUDET project

The goal of the EUDET project is the development and construction of infrastructure to permit detector R&D for the international linear collider (ILC) with larger scale prototypes. It encompasses major detector components: the vertex detector, the tracker and the calorimeters. We describe here the status and plans of the project with emphasis on issues related to data acquisition for future test beam experiments.

Pre-emption in resource-constrained project scheduling

The Resource-Constrained Project Scheduling Project (RCPSP), together with some of its extensions, has been widely studied. A fundamental assumption in this basic problem is that activities in progress are non-preemptable. Very little effort has been made to uncover the potential benefits of discrete activity pre-emption, and the papers dealing with this issue have reached the conclusion that it has little effect on project length when constant resource availability levels are defined. In this paper we show how three basic elements of many heuristics for the RCPSP – codification, serial SGS and double justification – can be adapted to deal with interruption. The paper is mainly focussed on problem 1_PRCPSP, a generalization of the RCPSP where a maximum of one interruption per activity is allowed. However, it is also shown how these three elements can be further adapted to deal with more general pre-emptive problems. Computational experiments on the standard j30 and j120 sets support the conclusion that pre-emption does help to decrease project length when compared to the no-interruption case. They also prove the usefulness of the justification in the presence of pre-emption. The justification is a RCPS technique that can be easily incorporated into a wide range of algorithms for the RCPSP, increasing their solution quality – maintaining the number of schedules calculated.
