THE CHARACTERISTICS OF FINANCE IN THE MEIJI PERIOD (THE PERIOD OF TAKE‐OFF) [PDF]

open access: yesThe Developing Economies, 1967
The financiers and merchants had accumulated enormous amounts of capital by the end of the Tokugawa period. The finance of the Meiji period remained in the hands of these men hence reflected to a great extent a pre‐modern type of finance.Furthermore, the fact that the financial sector was able to contribute to increases in productivity and to become ...

Wave length and celerity downstream from a hydraulic jump

open access: yesRBRH, 2019
The wave period, i. e., the time interval which corresponds to a complete oscillation, is an important parameter of wave characterization. It allows the estimation of other important wave characteristics such as the length and celerity.

Comparison of the characteristic energy of precipitating electrons derived from ground-based and DMSP satellite data [PDF]

open access: yes, 2005
International audienceEnergy maps are important for ionosphere-magnetosphere coupling studies, because quantitative determination of field-aligned currents requires knowledge of the conductances and their spatial gradients.

不同场地类别对反应谱特征周期的影响

open access: yesDizhen xuebao
为探究不同场地类别对反应谱特征周期的影响,建立了包含四种场地类别的180个计算剖面,在现行 《建筑抗震设计规范》 GB 50011—2010中场地分类的基础上按照土的软硬程度进一步细分,以不同幅值的El Centro地震动作为输入地震动,采用一维等效线性化方法进行土层反应分析,计算得到场地地震动反应谱,规准化得到反应谱特征周期。结果表明:① 在同一类别场地中,随着等效剪切波速的增大,特征周期呈减小的趋势;② 在同一类别场地中,随着输入地震动强度的增大,特征周期也相应增大;③ 在不同类别场地中 ...

Characteristic multipliers for some periodic differential equations. [PDF]

open access: yesProceedings of the American Mathematical Society, 1969
Calculation of the characteristic multipliers is not routine since in general one does not know even one nontrivial solution of (1). However it is possible to obtain convergent series representations for the solutions and thus calculate approximate values for the multipliers [2], [8].

Transferable Utility Games with Uncertainty [PDF]

open access: yes, 2010
We introduce the concept of a TUU-game, a transferable utility game with uncertainty. In a TUU-game there is uncertainty regarding the payoffs of coalitions.
