域控制器架构车载通信安全测评技术及对策探究

随着汽车逐渐呈现“新四化”的发展趋势,其电子电气架构趋于模块化、集中化,出现了以域控制器架构为代表的集中式电子电气架构。文章首先从产生背景、典型架构设计和实际应用情况对域控制器架构进行了概述,其次分析了在域控制器架构下车载通信的安全威胁。基于存在的安全威胁,结合实际测试用例介绍了域控制器架构下车载通信安全的测评技术。最后从硬件安全模块、通信加密和认证、域间隔离三个角度提出了加强域控制器架构通信安全的合理建议。

MULTI-SHOP SCHEDULING PROBLEM

A new concept of multi-shop （M ） is put forward which contains all basic shops including open shop （O）, job shop （J ）, flow shop （F ） and hybrid flow shop （H ） so that these basic shop can be scheduled together. Several algorithms including ant colony optimization （ACO）, most work remaining （MWR）, least work remaining （LWR）, longest processing time （LPT） and shortest processing time （SPT） are used for scheduling the M. Numerical experiments of the M adopting data of some car and reC series benchmark instances are tested. The results show that the ACO algorithm has better performance for scheduling the M than the other algorithms, if minimizing the makespan （ Cmax^＊） is taken as the objective function. As a comparison, the separate shops contained in the M are also scheduled by the ACO algorithm for the same objective function, when the completing time of the jobs in the previous shop is taken as the ready time of these jobs in the following shop. The results show that the M has the advantage of shortening the makespan upon separate shops.

新建本科高校向应用型转变的方向与路径

新建本科高校向应用型转变是中国高等教育健康发展和大众化实现的应有之义和必然要求。以学术性和市场性为两个坐标建立二维的高校办学定位模型,来描述新建本科高校的办学定位。新建本科高校向应用型转变,既要对接需求,又要提升内涵,同时提升高校的市场性和学术性。在实施路径上,应该优先提升市场性,解决与需求对接的问题,在此基础上积极创造条件提高学术水平。新建本科高校的基层学术组织要实现由专业实体向学科实体的转变,对专业和学科的评价要实现由学科导向向需求导向的转变。
