Research on the Revenue recognition of Fitness Industry——Based on Company A
随着我国经济迅猛发展,人民生活水平不断提高,全民健身意识不断加强,健身开始成为一种潮流,相应的,健身房的数量也如雨后春笋般遍地开花。健身行业的发展吸引了大量的资本介入,但是因为健身房企业特殊的预付制经营模式,所以无论资本介入目的是财务投资还是产业整合,资本方都十分关注健身房企业的财务处理方式,而预付制模式下如何进行会计核算仍然是目前资本界尚在讨论的问题,不同的健身房企业往往根据其经营情况采取不同的财务模型,最终导致不同的健身房企业得到的财务数据缺乏数据上的可比性。健身房企业的会计处理特殊性,主要是因为其成本类型、服务性质、对外交易等方面与其他行业存在一定的差异,所以在现行会计准则下,收入的确认...With swift and violent development of economy, people’s living standard has been constantly improved and people’s consciousness of fitness increases continuously.

长江上游圆口铜鱼的食性分析
2010年春季(4—5月)、夏季(8月)和秋季(10月)在长江上游合江江段采用三层流刺网以3h为间隔昼夜24h连续采集圆口铜鱼样本,对其食物组成、昼夜摄食节律及季节摄食节律等进行分析和研究。结果显示圆口铜鱼的食谱较广,其食物种类包括软体动物、甲壳动物、鱼类、水生昆虫、寡毛类和植物碎片等,其中以淡水壳菜的相对优势度最高,说明圆口铜鱼是以肉食性为主的杂食性鱼类;平均饱满指数和平均充塞度的昼夜变化显示其昼夜摄食节律在春季表现为白昼型,而在夏季和秋季为晨昏型。摄食率随季节变化逐渐降低,春季摄食率最高,达93.33%;秋季摄食率最低,仅为78.21%;充塞度和饱满指数均表现出相似的季节变化,即春季摄食强度明显高于夏季和秋季,而夏秋两季之间差异不显著
An Empirical Examination on the Impact of Interest Rate, Stock Index and Commodity Index on RMB Exchange Rate -- Based on VAR-GARCH(1,1)-BEKK Model
自2001年12月我国正式加入世界贸易组织以来,我国的市场经济得到了很大发展,对外贸易也不断扩大,人民币汇率也越来越市场化;与此同时,以香港离岸人民币市场为代表的人民币离岸市场也得到了很大的发展,人民币也更加国际化。人民币不断深入的市场化和国际化,使得汇率对我国经济的影响进一步加大,对于人民币汇率的研究也更加有意义。 本文选取人民币汇率、利率、股指以及大宗商品价格指数作为研究对象,通过构建VAR模型,实证检验了他们之间的相互关系。首先,本文研究了在岸与离岸市场人民币即期汇率价差与利率、股指以及大宗商品价格指数之间的相互关系,我们发现在岸与离岸市场的人民币利率差值与人民币即期汇率价差之间有着很...Since December 2001, China formally joined in the World Trade Organization, China's market economy has greatly developed, international trade has also been increasing and the exchange rate of RMB is more and more marketization.

Real-time identification of time-varying structures and integration with vibration control based on extended Kalman Filter with unknown inputs
建筑结构的参数识别与损伤诊断是结构健康监测领域中的一项重要课题。在过去的数十年内,业内许多专家与学者给出了理论各异的,基于结构振动响应的参数识别与损伤诊断方法。然而,这其中的许多方法,大都是针对于时不变系统的。但在重大荷载发生时(如高烈度地震等),结构单元发生损伤,它的物理参数(如刚度等)在荷载作用中是随时间变化的。为了实时地捕捉这一变化,结构健康监测系统应该具备在线地识别时变结构参数的能力。 因此本论文在第二章,在前人基础上得到了基于改进的自适应卡尔曼滤波的时变系统在线识别方法。与现有文献相比,该方法利用了自适应因子来反映结构参数的变化,能够仅在结构响应数据部分已知的情况下,在线地识别结...Structural identification and damage detection are significant subject in Structural health monitoring(SHM) technology. In the past few decades, different experts and scholars have come up with different theories and methods of Structural identification and damage detection based on structural vibration response. While, many of these identification methodologies are mostly aimed at the time-invari...学位:工学硕士院系专业:建筑与土木工程学院_结构工程学号:2532014115177
Effect of virtual power plant scheme on the supply and demand sides based on the techno-economic analysis
北九州市立大学博士(工学)This research proposed a comprehensive method for analyzing the feasibility of using a Virtual Power Plant (VPP) to benefit both the plant and demand sides. First, the energy-saving potential of a VPP composed of a photovoltaic and energy storage system was explored. Second, the economic performance of the VPP was evaluated based on a payback period and total life cycle cost analysis. Then, considering the imbalance of the benefits between the demand and plant sides, cooperative game theory was applied to explore the cooperation potential. The influence of government subsidy policies on both the plant and demand sides was a simultaneous concern. Finally, the profit of the alliance, comprising both the demand and plant sides was allocated, based on the Shapley value. This study highlights the excellent energy-saving potential from implementing a VPP. This research provides policy guidance for the Japanese government to promote VPPs in the future.doctoral thesi
耦合生态系统服务供求关系的生态安全格局动态分析——以闽三角城市群为例
实现分区管理是缓解城市群生态安全空间差异的有利途径。基于供求理论构建了生态系统服务供求关系动态模型框架,并利用供给与需求的象限区划表征闽三角城市群生态安全格局;在不同的尺度变换上,运用价值单量修正模型、INVEST生境质量模型、景观指数模型、生态韧性模型、熵权法等方法综合测度城市群生态系统服务供求水平,实现生态安全格局的分区化;引入环境库兹涅茨曲线理论解析区域生态安全格局现状和成因;数据分析借助Arc GIS可视化表示。研究发现:(1)闽三角城市群存在50%区域属于生态安全高供给失衡区,其中70%属漳州市境内;32.14%属于高需求失衡区,集中于市辖区与沿海地区;17.86%属于双维度失衡区;未存在单元位于双维度共赢区上。(2)区域生态系统服务供给颇佳而需求滞后,城市群东南沿海区域与周边区域格局差异明显,供给(需求)呈现由沿海向内陆梯次增(减)的空间分异规律。(3)城市群尚处于生态安全库兹涅茨曲线的\"两难阶段\",同时导致了城市群生态安全格局空间异质性的产生。国家重点研发计划(2016YFC0502901);;国家自然科学基金项目(41771500
