Power integrity （PI） has become a limiting factor for the chip＇s overall performance, and how to place in-package decoupling capacitors to improve a chip＇s PI performance has become a hot issue. In this paper, we propose an improved transmission matrix method （TMM） for fast decoupling capacitance allocation. An irregular grid partition mechanism is proposed, which helps speed up the impedance computation and complies better with the irregular power/ground （P/G） plane or planes with many vias and decoupling capacitors. Furthermore, we also ameliorate the computation procedure of the impedance matrix whenever decoupling capacitors are inserted or removed at specific ports. With the fast computation of impedance change, in-package decoupling capacitor allocation is done with an efficient change based method in the frequency domain. Experimental results show that our approach can gain about 5× speedup compared with a general TMM, and is efficient in restraining the noise on the P/G plane.  相似文献   

高校教师的主体责任对考试诚信的影响分析     

李建华 《教育教学论坛》2020,(12):33-35

大学生考试诚信问题越来越严重,问卷调查结果显示学生普遍认为高校教师能够严格要求对考核诚信有着非常重要的影响。通过对高校教师和学生之间博弈过程的分析,发现如果能够落实高校教师的主体责任,高校教师和学生之间博弈的纳什均衡能够提高学生的考试诚信水平。  相似文献   

明清之际一个普通士人的人生际遇——王崇简生平与出处     

刘仲华 《石家庄学院学报》2007,9(5):61-66

王崇简在明朝灭亡之前考取进士,未及授官,李自成军队便进入北京,遂携家眷流寓南方,两年后返回北京。自顺治初年授官后,仕途顺遂,康熙初年以原官致仕。可以说,在明亡前夕,王崇简虽然参加复社,对时局感悲不已,但并没有抱定"君亡与亡"的决心;清军入关后,他南奔避祸,期望南明政权恢复旧土,但无望而北返,也无意隐居埋名,最终投效清廷,荣宠备至。  相似文献   

Addressing plagiarism in online programmes at a health sciences university: a case study     

Helen Ewing  Ade Anast  Tamara Roehling 《Assessment & Evaluation in Higher Education》2016,41(4):575-585

Plagiarism continues to be a concern for all educational institutions. To build a solid foundation for high academic standards and best practices at a graduate university, aspects of plagiarism were reviewed to develop better management processes for reducing plagiarism. Specifically, the prevalence of plagiarism and software programmes for detecting plagiarism was investigated. From that information, best practices for responding to plagiarism were developed and a process to enhance academic integrity was instituted. The results were impressive, the incidence of plagiarism offences reduced by half in three years, and by 75% among the English as a second-language student population.  相似文献   

Ghostwriters guaranteeing grades? The quality of online ghostwriting services available to tertiary students in Australia     

Lisa Lines 《Teaching in Higher Education》2016,21(8):889-914

Ghostwriting is difficult to detect, it has the potential to be high quality, and universities do not currently have adequate policies in place to police it. Determining the quality of the ghostwriting services available to tertiary students is of vital importance because underestimating the potential for students to use these services to pass their courses affects universities’ ability to detect their use and counteract their prevalence. This study examines the service being advertised to students by the 30 top-ranked ghostwriting websites. The study examines the quality of the service being offered by purchasing 2 essays from 13 of these businesses, 1 undergraduate and 1 postgraduate. These essays were graded by three academics who believed they were grading real student papers. The results of the study are alarming because they imply that had these essays been submitted to a university, the majority of them would have passed without any plagiarism detected.  相似文献

美国大学荣誉制度探析     

宫艳华 《比较教育研究》2011,(11):77-80

美国大学的荣誉制度是一项规约大学生学术研究行为的制度,强调以学生自我管理为中心,以信任学生的道德意识和责任感为前提。荣誉制度作为遏制大学生学术不诚信行为的有效措施可以为我国大学校园的诚信建设提供经验,本文从四个方面对荣誉制度进行介绍:荣誉誓词、荣誉委员会、对违规行为的处理程序以及对违规行为的惩罚措施,并进一步探讨了实施荣誉制度的成效。  相似文献   

中学生诚信心理发展特点的研究     

樊洁  邓敏  胡发稳 《蒙自师范高等专科学校学报》2011,(2):97-101

运用诚信心理问卷,对1008名中学生在诚信倾向、诚实认知、诚信监控、诚信体验、信用认知等五个方面的诚信心理进行测查.研究结果表明,中学生的诚信心理发展特点是:在年级、性别、学校所处位置、学习成绩等四方面存在显著差异;而在民族变量上,中学生的诚信心理不存在显著差异.并且男生的诚信倾向和诚信体验两个维度好于女生,而诚信监控不如女生好;高二年级的诚信水平最高,与初一、初二、初三、高一、高三五个年级存在显著差异;农村学生的诚信倾向明显好于城镇学生,但诚实认知和诚信体验不如城镇学生好;优秀学生的诚信监控优于非优秀学生,而信用认知不如非优秀学生好.  相似文献
