简介：以便满足室内的照明的要求，一个带的日光灯模型被设计，没有insteading，它能代替传统的荧光灯另外的电源供应建立。模型的光性质用光分析软件被模仿。它的发光效率是大约30.4lm/W，并且当距离是在模型的中心之间的1.5m并且测量点时，照度是大约38勒克司。与领导模型的理论上优化的设计，实验基于在实验室的最佳的模拟的结果被进行验证建议领导模型的表演，它在6W到达大约0.8的一个电源因素。模拟结果与测量价值是很类似的。模拟方法是为点亮光设计带的有效工具之一，这被证明。

简介：稀少的代码多重存取(SCMA)是为下一活动通讯的一个竞争nonorthogonal存取计划。作为分享系统的一个多用户，SCMA采用为在接收装置译码计划传递算法(MPA)的消息，但是它的反复的方法导致高计算的复杂性。因此，基于可变节点(VMPA)传递算法的一条连续消息在这份报纸被建议。在原来的MPA使一些成为微妙的改变到消息更改，VMPA能极大地减少译码计划的全面计算复杂性。而且，考虑那连续结构可以增加译码延期，一个新奇组织计划基于稀少的矩阵被用于VMPA。模拟结果证实新算法，作为组织VMPA(G-VMPA)称为，能比MPA完成在小点错误率(BER)和计算复杂性之间的更好的折衷。
