On a new stochastic global optimization algorithm based on censored observations

In this paper a new algorithm is proposed for global optimization problems. The main idea is that of modifying a standard clustering approach by sequentially sampling the objective function while adaptively deciding an appropriate sample size. Theoretical as well as computational results are presented.     

旧式大型工具显微镜数显化

大型工具显微镜是用途较广的精密长度计量仪器,主要用于测量螺纹中径、圆柱的直径等。目前实验室和工厂现有的仪器属50年代生产的老型号产品,用目视螺旋测微鼓上的刻度读数,人工记录和处理数据,测量时费时费工。针对大型工具显微镜数显化的问题,阐述了光栅、光电显微镜、单片机、新型传感器在数显上的应用。利用新技术和新型传感器改造老设备,使其实现数字化和智能化,以提高测量效率和测量精度。改造的结果表明,改造后的仪器测量效率大大提高,精度可提高一个数量级。

Discrete storage processes and their Poisson flow and fluid flow approximations

Consider discrete storage processes that are modulated by environmental processes. Environmental processes cause interruptions in the input and/or output processes of the discrete storage processes. Due to the difficulties encountered in the exact analysis of such discrete storage systems, often Poisson flow and/or fluid flow models with the same modulating environmental processes are proposed as approximations for these systems. The analysis of Poisson flow and fluid flow models is much easier than that of the discrete storage processes. In this paper we give sufficient conditions under which the content of the discrete storage processes can be bounded by the Poisson flow and the fluid flow models. For example, we show that Poisson flow models and the fluid flow models developed by Kosten (and by Anick, Mitra and Sondhi) can be used to bound the performance of infinite (finite) source packetized voice/data communication systems. We also show that a Poisson flow model and the fluid flow model developed by Mitra can be used to bound the buffer content of a two stage automatic transfer line. The potential use of the bounding techniques presented in this paper, of course, transcends well beyond these examples.Supported in part by NSF grant DMS-9308149.
