锁模半导体激光器产生带宽极限的超短光脉冲

利用主动锁模技术,以光在外腔中的往返频率调制注入电流,在外腔中加入F-P标准具(Fabry-Perot etalon)后,在国內首次获得了带宽极限的可调谐完全锁模半导体激光超短脉冲。该脉冲源可望用于高速光通信、光孤子通信等领域。

浅析影响因子的局限性

目前大量的机构用论文的被引用率、期刊的影响因子和被 SCI收录的情况作为评价个人、期刊和科研机构之影响力或水平高低的一个重要指标。但却忽略了不同学科的特殊性以及学科的规模、发展速度等非科学的因素对影响因子的局限 ,这就形成了对许多专业的不公平评价 ,因而必须对普通的影响因子加以修正     

创业教育探究

创业教育是未来主导性教育体制与教育形态之一 ,它植根于创业概念、创业现象、创业学、创业大赛、创业者的研究之中。创业教育走过了一条从无到有 ,从精英到平民的道路。创业教育的兴起是国际政治、经济、文化、教育、价值竞争的结果     

DBF系统的通道校正技术

描述了影响DBF系统特性的主要因素,研究了阵元间互耦对自适应方向图旁瓣和零深的影响及校正方法,讨论了在DBF阵中校正接收通道幅、相误差和I/Q支路正交误差的技术途径。计算机模拟和测试证明,按照所述方法进行校正可以得到满意的结果。另外,为了减小I/Q支路产生正交误差,建议采用中频直接采样和数字化的接收机方案。     

Higher education outcomes, graduate employment and university performance indicators

Summary.  Official employment-related performance indicators in UK higher education are based on the population of students responding to the 'First destination supplement' (FDS). This generates potentially biased performance indicators as this population of students is not necessarily representative of the full population of leavers from each institution. University leavers who do not obtain qualifications and those who do not respond to the FDS are not included within the official analysis. We compare an employment-related performance indicator based on those students who responded to the FDS with alternative approaches which address the potential non-random nature of this subgroup of university leavers.     

Tasmania Together? A disability critique of a social plan

The 'Tasmania Together' social futures plan for Tasmania is critically examined. Authored by a Tasmanian Government appointed Community Leaders Group, on behalf of the people of Tasmania, the plan is supposed to deliver a better Tasmanian society by 2020, based upon community consultation. Rather than a step-forward in democracy, the process serves to remove the democratic rights of people, especially those who are disadvantaged. A critique from a disability perspective is offered, which suggests that this social plan constitutes a form of institutionalised disablism.
