Nonlinear entanglement witnesses based on continuous-variable local orthogonal observables for bipartite systems

In this paper, a nonlinear entanglement witness criterion based on continuous-variable local orthogonal observables for bipartite states is established, which is strictly stronger than the the linear entanglement witnesses criterion introduced by Zhang et al. (Phys. Rev. Lett. 111:190501, 2013). This criterion is particularly applied to two-mode Gaussian states yielding a criterion in terms of the covariance matrix. Comparison with CCNR criterion is discussed.

Single event upset rate modeling for ultra-deep submicron complementary metal-oxide-semiconductor devices

Based on the integral method of single event upset(SEU) rate and an improved charge collection model for ultra-deep submicron complementary metal-oxide-semiconductor(CMOS) devices, three methods of SEU rate calculation are verified and compared. The results show that the integral method and the figure of merit(FOM) methods are basically consistent at the ultra-deep submicron level. By proving the validity of the carrier collection model considering charge sharing, the applicability of two FOM methods is verified, and the trends of single-bit and multiple-bit upset rates for ultra-deep submicron CMOS are analyzed.

Regularized query classification using search click information

Hundreds of millions of users each day submit queries to the Web search engine. The user queries are typically very short which makes query understanding a challenging problem. In this paper, we propose a novel approach for query representation and classification. By submitting the query to a web search engine, the query can be represented as a set of terms found on the web pages returned by search engine. In this way, each query can be considered as a point in high-dimensional space and standard classification algorithms such as regression can be applied. However, traditional regression is too flexible in situations with large numbers of highly correlated predictor variables. It may suffer from the overfitting problem. By using search click information, the semantic relationship between queries can be incorporated into the learning system as a regularizer. Specifically, from all the functions which minimize the empirical loss on the labeled queries, we select the one which best preserves the semantic relationship between queries. We present experimental evidence suggesting that the regularized regression algorithm is able to use search click information effectively for query classification.     

基于BIRIS的海运物流服务平台案例研究

With increasing competition in international marine logistics service industry, the voice of improving marine logistics service for reducing operation cost and improving service quality is much higher. Aiming at the marine logistics services between Weihai and Korea, this paper makes a case study to design a BIRIS-based public platform for this service. Firstly, current business scenarios of Sino-Korea marine logistics services are briefly analyzed and some business issues that need to be solved urgently are listed, e.g., lack of effective communication channel between cargo owners and various service providers, low coordination efficiency between different service providers etc. Aiming at these problems, a BIRIS based marine logistics service platform is designed. TO-BE business scenario, SOA techniques for developing such platform, and some examples of identifying services, designing service interfaces and designing portal for each service provider, are elaborately shown.     

基于遗传算法的流水线车间工序调度问题研究

流水线作业是现代生产线最常用的技术.在流水线生产过程中,某种产品需要很多工序按照一定的顺序才能完成,根据生产计划每台设备可以为同一工件做相对应的工序,而根据实际情况有的工人可以熟练操作多个工序.因此建立好车间加工工序与人员之间的优化配置就显得尤为重要,它可以缩短工期,增加经济效益.基于遗传算法给出人员与工序的最优调度决策,并采用一个简单的例子进行了仿真验证.
