Area-time associated test cost model for SoC and lower bound of test time

A novel test access mechanism (TAM) architecture with multi test-channel (TC) based on IEEE Standard 1500 is proposed instead of the traditional sub-TAM structure. The cost model of an area-time associated test and the corresponding lower bound of system-on-chip (SoC) test time are established based on this TAM architecture. The model provides a more reliable method to control the SoC scheduling and reduces the complexity in related algorithm research. The result based on the area time associated test cost model has been validated using the ITC’02 test benchmark.     

中学数学学困生题后反思的元认知技能培训

在教学环境下,如何提高个体的元认知水平,一直是元认知研究领域的焦点课题.通过控制课堂教学,对“题后反思”法的训练效果进行研究是很有必要的,由此得出:(1)数学学优生与学困生在元认知技能方面存在显著性的差异;(2)经题后反思的短期培训后,数学学困生在元认知技能方面有显著性的提高,但是与学优生的差异仍然显著.

Does the “Pupil Enterprise Programme” Influence Grades Among Pupils With Special Needs?

This paper asks whether the Pupil Enterprise Programme (PEP) is a suitable working method for improving academic performance among pupils with special needs. Overall, 20% of pupils participate in PEP at some point during lower secondary school. Results from multilevel regression modelling indicate that pupils with special needs who have participated in PEP attain better grades in Written Norwegian and Mathematics than those pupils with special needs who did not participate in PEP. The difference between PEP participants and non-participants in Written English was insignificant. The positive results for Norwegian and Mathematics seem to be related to the organisation and content of PEP. The data are from a study of 1,880 pupils in the 10th Grade.

四能级原子自发辐射的量子相干特性

研究四能级原子的自发辐射。原子激发态是不稳定的,其必然会自发地向低能级衰变,产生自发辐射现象。本文针对四能级原子仅存在自发辐射的情况,基于量子力学和Kraus算子理论,利用约化密度矩阵方法,得到四能级原子自发辐射的密度矩阵元演化规律,从而分析量子态相干特性。
