基于CVM的鼓浪屿旅游资源经济价值的评估

本文运用条件价值评估法,通过对游客的门票支付意愿调查,对鼓浪屿旅游资源的经济价值进行评估。评估运用SPSS17.0软件,采用卡方列联表相关度分析对支付意愿及支付意愿值的影响因素进行相关分析,结果表明：被调查者的年龄、受教育程度与支付意愿显著相关,而性别、月收入和职业等因素与支付意愿相关不显著;年龄、职业、受教育程度和性别与支付意愿值显著相关,月收入与支付意愿值关系不大。     

基于路网的移动对象k近邻查询方法

针对基于路网的移动对象k近邻查询方法论Island的3点不足进行了研究,包括路网建模、交通堵塞探测方法的提出以及查询效率不高。提出了改进方法Island+,采用过度矩阵表示转向以及区域半径优化方法,结果证明提高了查询效率,查询时间和I/O对磁盘页访问次数明显少于原方法。

光伏发电系统中逆变器的研究与应用

光伏并网发电系统由太阳电池组件、并网逆变器、计量装置及配电系统组成,太阳能能量通过光伏阵列产生的是直流电能,需要通过逆变器把直流电转换成与电网同频率、同相位的交流电才能并到电网。并网逆变器作为光伏阵列与电网的接口装置,起着关键的作用。随着光伏发电系统的发展,并网发电系统中使用的逆变器得到了越来越多的关注。本文从阐述并网...     

ACP1000核电常规岛主给水泵内部流动数值模拟与优化

以第三代核电ACP1000常规岛主给水泵为研究对象,建立双吸叶轮流场三维模型,基于CFD方法,采用标准k-ε湍流模型和可升级壁面函数法对其进行三维定常湍流计算。以叶轮前盖板流线为优化参数,基于Bezier函数型流线设计方法对叶轮前盖板提出了优化设计方案。通过比较叶轮内流场增压特性以及水力性能曲线,结果表明,优化后的方案具有高扬程高效率的特点,设计参数满足ACP1000核电机组常规岛主给水泵性能要求。     

Evaluation of energy efficiency and renewable energy generation opportunities for small scale dairy farms: A case study in Prince Edward Island,Canada

Prince Edward Island (PEI) is the smallest province in Canada measuring about 5700 km² in area with a population of around 130,000 people. Small family farm operation is part of the Island's way of life. However, the dairy industry in North America is undergoing significant structural change. Statistics show a significant decline in the small dairy farms industry, while the number of large operations has been increasing. Advantages for large operations include purchasing energy in large quantities with better price margins and the inherent economy of scale created by such breaks. One strategy for small-scale farms to become competitive is to reduce their energy-related operational costs and greenhouse gas emissions. This can be achieved through taking energy efficiency steps, reducing overall energy consumption and generating energy through renewable energy resources and technologies. This paper uses a case study of a small dairy farm in Oyster Bed Bridge, PEI to gain insight into the direct use of energy within small dairy farms. An energy audit methodology is used to determine the energy intensity of the farm as well as energy efficiency opportunities. The paper also assesses the feasibility of meeting part of the energy demand of the farm with renewable energy generation. Energy efficiency recommendations for the case study farm include lighting retrofitting and regular maintenance of refrigeration condenser units. Renewable energy generation findings include the potential use of an anaerobic digester or a 25 kW wind turbine to generate the majority of the operation's energy.     

Initiating Change: Architecturing the Body-Environment with Arakawa and Gins

New York-based artists Shusaku Arakawa (1936–2010) and Madeline Gins (1941–) used architecture in their work in an approach that they have referred to as ‘architecting’. Jondi Keane explains how as artists-turned-architects, Arakawa and Gins have not been particularly interested in innovating architecture, but in approaching architecture as a way to innovate, or change the world'.     

The Vitality of Matter and the Instrumentalisation of Life

Artists and researchers Oron Catts and Ionat Zurr of SymbioticA, based at the School of Anatomy, Physiology and Human Biology at the University of Western Australia, are internationally renowned as pioneers in the field of biological arts, challenging audiences with their tissue engineering projects. Catts and Zurr discuss how synthetic biology has increasingly become ‘the new frontier for exploitation’ and why there is currently ‘a resurgence of the application of engineering logic in the fields of the life sciences’ in which life itself becomes a raw material.     

Embedding Intelligence: Architecture and Computation at Grimshaw,NY

Research and development at Grimshaw is concentrated in two groups: Design Technology (DT) and Industrial Design (ID). Seth Edwards from Grimshaw's DT group explains how these dual hubs provide an essential resource for the practice, offering expertise in complex geometry, rapid prototyping and construction. He illustrates three projects, originating in the New York office, that exemplify this approach.
