Risk and reliability assessment about a manufacturing issue in a power MOSFET for automotive applications

In the automotive semiconductor industry, risk assessments are requested by customers on quality incidents that happen in the assembly line or in field. More rarely, in a die business context, such a study is requested about a defect observed during the optical inspection performed by the customers on the known good dice after assembly. This article deals with the case of pin holes in the top metal surface of a MOSFET component. The risk assessment is addressing detection, occurrence and severity of the defect: this implies process and failure analysis. Also, reliability has been carried out, by completing accelerated and typical stress tests.

一种基于mMIMO技术的应用落地实践

为应对移动通信业务量的迅猛增长,以及对信息传输的速率、时延、可靠性等各方面都提出了更高的要求,大规模多进多出(Massive MIMO,m MIMO)因其空间资源挖掘的独特优势而获得青睐与重视,可实现系统频谱和能量效率的极大化,已成为5G的关键技术之一。文章介绍了m MIMO的关键技术原理,提出了针对不同TR数的设备进行差异性部署的方法,同时介绍了m MIMO最关键的波束赋形技术的优化思路和详细案例,为后续打造低成本优质5G精品网络具有重要意义。     

Key-Attributes-Based Ensemble Classifier for Customer Churn Prediction

Recently, it has been seen that the ensemble classifier is an effective way to enhance the prediction performance. However, it usually suffers from the problem of how to construct an appropriate classifier based on a set of complex data, for example, the data with many dimensions or hierarchical attributes. This study proposes a method to constructe an ensemble classifier based on the key attributes. In addition to its high-performance on precision shared by common ensemble classifiers, the calculation results are highly intelligible and thus easy for understanding. Furthermore, the experimental results based on the real data collected from China Mobile show that the key-attributes-based ensemble classifier has the good performance on both of the classifier construction and the customer churn prediction.

关于《卓越绩效评价准则》国家标准实施中的难点讨论

根据国家质检总局在2004年8月30日发布的GB/T19580<卓越绩效评价准则>国家标准的要求,结合五年来质量管理奖评审和企业自我评价发现的问题,我们开展了<准则>实施中的难点分析.本文介绍其中的部分内容:一、将"领导"置于过程中,而不是摆在"职位上;二、组织在制定战略的过程中必须十分重视资料和信息的输入;三、组织应致力于提供更多的顾客价值;四、组织应关注员工职业生涯发展;五、过程设计应体现增值性、敏捷性、系统性;确保绩效测量系统的一致性和敏感性.     

A greedy algorithm for the two-level nested logit model

We consider the assortment optimization problem under the classical two-level nested logit model. We establish a necessary and sufficient condition for the optimal assortment and develop a simple and fast greedy algorithm that iteratively removes at most one product from each nest to compute an optimal solution.
