关键词： 栈   数据结构   线性表   表达式求值  

摘要： 栈是限定只能在表的一端进行插入和删除的线性表。根据栈的这种存取特征,栈也被称为后进先出表。生活中的穿衣脱衣、九连环游戏、括号匹配等都是应用栈的这一特点。栈的基本操作包括入栈、出栈、得到栈顶元素、判断栈空、判断栈满等等。在该文中我们将讨论栈在中缀表达式求值、后缀表达式求值以及后缀表达式转换成中缀表达式中的应用。

关键词： Multi resolution   Multi phase flows   Sharp interface methods   Data structure   Parallel computing  

摘要： In this work, we present a block-based multi-resolution method coupled with a sharp interface model (MR-SIM) for the high-resolution simulation of multi-phase flows, where data structure and adaptive multi-resolution approach are tailored to achieve high computational efficiency. The method updates the dynamic topological data structure according to two separate procedures: (i) tracking of the interface position, and (ii) MR analysis on each individual phase. High efficiency is achieved by employing a storage-and-operation-splitting pyramid data structure, in which any two adjacent blocks partially overlap while the overlapping parts share the same data in memory. The non-overlapping data are distributed into fine-grained data packages and stored within a memory pool. The proposed narrow-band technique for the level-set-based interface method also increases the computational and memory efficiency greatly by restricting all interface-relevant data and operations to a neighborhood of the interface. A broad set of test simulations is carried out to demonstrate the potential and performance of the MR-SIM approach. (C) 2014 Elsevier Inc. All rights reserved.

摘要： As economic globalization and information industry develop at top speed, Internet has penetrated into all walks of life rapid, with an immeasurable impact on all aspects of people's life. Computer technology is an integral part in the evaluation of audit system, technically prepared for application of cloud data structure in the evaluation of audit system. Based on the concept of Internet cloud data structure, this paper constructs a new audit system evaluation model. Firstly, it performs a theoretical analysis of Internet cloud data structure audit system;then it explores applications of cloud data structure audit system;finally, feasibility of cloud data structure audit system is evaluated by means of AHP and fuzzy analysis. It is found that the system has incomparable superiority in audit practices.

关键词： STEP   CAPP   network part program   pallet configuration  

摘要： The adoption of alternative process plans, that is, process plans that include alternative ways of machining a workpiece, can improve system performance through a better management of resource availability. Unfortunately even if this opportunity is deeply analysed in literature, it is not frequently adopted in real manufacturing practice. In order to fill this gap, this article presents the network part program (NPP) approach for the machining of multiple fixture pallets. The NPP approach is based on the STEP-NC data structure which supports nonlinear sequences of operations and process flexibility. In the NPP approach, a machining system supervisor defines the machining sequences and generates the related part programs just before the execution of the pallet. This article provides an approach with high scientific value and industrial applicability based on the integration of new and existing process planning methods. A real industrial case study is considered in order to show that in real applications the final quality is unaffected by the change of the sequence of the operations due to the employment of nonlinear process plans. Since the results appear very encouraging, the proposed approach is a possible solution to accelerate the adoption of nonlinear process planning in real manufacturing practice.
