小户型设计中的扩展艺术

由于房价高企,城市人口增多,小户型成为年轻人的热门选择。户型虽小但是生活却不会因此而缩小,如何在有限的空间中创造出最大的使用功能,是目前很受关注的一个问题。因为小户型的空间划分和布局受到户型和面积的限制,装修时往往导致房屋空间功能不全,或者房屋的整体协调性美观程度降低。因此在装修前,需要按照自己的需求对空间进行重新划分,使其在更合理化、人性化,同时整体协调,不杂乱。只要有合理的布局,小户型也可以拥有舒适的生活空间。

Partition ratios, Pareto optimal cake division, and related notions

We consider the problem of partitioning a ‘cake' C among n players. Various criteria have been considered for deciding whether a partition P₁,P₂,…,P_n of C, where piece P_i goes to player i, is a ‘good' partition. See, for example, Barbanel (1996) [Barbanel, J.B., 1996. Super envy-free cake division and independence of measures. J. Math. Anal. Appl. 197, 54–60] or Brams and Taylor (1996) [Brams, S.J., Taylor, A.D., 1996. Fair Division: From Cake-Cutting To Dispute Resolution. Cambridge Univ. Press]. In this paper we study certain real numbers (the ‘partition ratios' of this paper's Section 2) which can be associated in a natural way with any partition. We show that various types of products of these numbers provide us with useful information about certain trades and transfers between players.     

Mark-Choose-Cut Algorithms For Fair And Strongly Fair Division

This paper proposes a new criterion to evaluate algorithms for cake division, by the number of resulting pieces. Then, inspired by the idea of "cut-and-choose", we present "mark-choose-cut" algorithms for fair and strongly fair cake division problems. They are game-theoretic algorithms. The number of resulting pieces is bounded by 2 × 3n-2 + 1 and 4 × 3n-2 + 1, for fair and strongly fair division respectively.     

区域经济协调发展中的不平衡增长

推进区域经济协调发展是我国经济发展战略中的重要内容之一,但协调发展并不意味着平均主义,由于每个城市在区域内分工网络中所充当的角色不同,不平衡增长是必然的。     

简论跨世纪的日本地方分权改革

进入90年代以来,日本社会政治,经济诸方面发生了深刻变化,对传统的中央集权型行政体制提出了严峻的挑战,面对新形势,日本近几届内阁在行政改革方面均加大了力度,地方分权被日本舆论称为继明治维新,战后改革之后的“第三次革命”,作为一项跨世纪的系统工程,经过近10年的细密研讨,新千年伊始地方分权改革将进入具体实施阶段,一种新型扣央地方关系呼之欲出。     

Re-examining online customer experience to include purchase frequency and perceived risk

This research examines the important emerging area of online customer experience (OCE) using data collected from an online survey of frequent and infrequent online shoppers. The study examines a model of antecedents for cognitive and affective experiential states and their influence on outcomes, such as online shopping satisfaction and repurchase intentions. The model also examines the relationships between perceived risk, trust, satisfaction and repurchase intentions. Theoretically, the study provides a broader understanding of OCE, through insights into two shopper segments identified as being important in e-retailing. For managers, the study highlights areas of OCE and their implications for ongoing management of the online channel.     

高炮随动系统自动测试中正弦机发送频率的确定

在某型高炮随动系统测试中,正弦机的发送频率直接影响着输出信号的平滑度,从而会影响测试的精度。为了避免在正弦机运行过程中,计算耗用过多机时,在正弦机发送之前,先计算出每个位置信号、前馈信号的数值,存放于内存中。本文根据该正弦机信号的特点,分析了几种正弦机角位置信号发送频率方式的优缺点,确定了正弦机发送频率的方式。
