浅谈水果的气调储藏

气调储藏(CA储藏)即调节环境气体成分的储藏法。其简要原理是改变仓库或包装中正常空气组成,降低含氧量,增加二氧化碳含量,以减弱鲜活食品的呼吸强度并抑制微生物的发展和食品化学成分的变化。气调储藏还须有低温条件配合才能收到良好的储藏效果。因此气调储藏可以看作是低温储藏的一种强化手段。一些发达国家利用气调法储存的水果已达很高的比例,如英国采用气调储存的水果已占产量的60％。

Visual displays: analytical study and applications to graphs and real data

Principal axis methods such as principal component analysis (PCA) and correspondence analysis (CA) are useful for identifying structures in data through interesting planar graphic displays. However, some kinds of data sets can be dealt alternatively with PCA or CA. This paper focuses on methods, such as PCA and CA, and on visual displays. Our aim is to illustrate the implications for a potential user of selecting either method, and its advantages and disadvantages, from an applied point of view. This is a matter covered broadly in textbooks and elsewhere considering theoretical arguments. Our purpose is to contribute to the comparison between these methods, over the same data set, in order to illustrate them for the practitioner. In the first part of this paper we present a novel analytical study of a binary matrix associated with a non-oriented axis-symmetric graph and show that CA outperforms standardized PCA for the reconstitution and visualization of such kind of graphs. In the second part we present a case using real data dealing with the distribution of employees in different economic sectors for the countries of the European Union, analyzed by means of standardized PCA and two-way CA, in order to see the differences between the two methods in practice.     

分布式存储系统调查

随着现代IT系统的发展,数据的规模越来越庞大,并且增速也越来越快,因此传统的存储系统遇到了前所未有的挑战。目前,已经有很多公司和组织使用分布式存储系统对其海量数据进行存储和管理,并且越来越多的其他用户也希望能够将其应用于云存储系统中,从而获得更好的性能和更低廉的价格。分布式存储系统作为云存储技术的基础得到了越来越广泛的应用,其中存储虚拟化常常被用于私有云存储的方案中,而面向对象的存储和分布式文件系统被更多地应用于公有云的系统中。文章介绍了目前流行的分布式存储系统,并为用户选择分布式存储系统提供参考。

On the behavior of commodity prices when speculative storage is bounded

This paper investigates the implications of bounded speculative storage, storage bounded from below at zero and above at a capacity, on commodity prices. Binding capacity mirrors the non-negativity constraint on storage and leads to negative price spiking and higher volatility when the market is in deep contango, i.e. low current prices at high stock levels. With bounded storage there is no need to restrict storage to be costly to ensure a rational expectations equilibrium. This allows the model to cover a wide range of storage technologies, including free and productive storage. We also provide an alternative expression for speculative prices that highlights the key role of the storage boundaries. The competitive equilibrium price is the sum of discounted future probability weighted boundary prices. The boundary prices can be viewed as dividends on commodities in storage reflecting the realization of economic profits from storage.

Carbon performance and corporate financial performance: The moderating role of consumer awareness of corporate social responsibility

The paper detects the association between carbon performance (CP) and corporate financial performance (CFP) and the moderating role of consumer awareness (CA) of corporate social responsibility (CSR). We find that CP has consistent positive impacts on CFP in the short and long term, whereas CA has opposite moderating effects on CFP. These results indicate that companies should increase corporate value by improving CP. In addition, improving CA of CSR is an effective way to promote CFP.     

iSDS: a self-configurable software-defined storage system for enterprise

ABSTRACT

Storage is one of the most important aspects of IT infrastructure for various enterprises. But, enterprises are interested in more than just data storage; they are interested in such things as more reliable data protection, higher performance and reduced resource consumption. Traditional enterprise-grade storage satisfies these requirements at high cost. It is because traditional enterprise-grade storage is usually designed and constructed by customised field-programmable gate array to achieve high-end functionality. However, in this ever-changing environment, enterprises request storage with more flexible deployment and at lower cost. Moreover, the rise of new application fields, such as social media, big data, video streaming service etc., makes operational tasks for administrators more complex. In this article, a new storage system called intelligent software-defined storage (iSDS), based on software-defined storage, is described. More specifically, this approach advocates using software to replace features provided by traditional customised chips. To alleviate the management burden, it also advocates applying machine learning to automatically configure storage to meet dynamic requirements of workloads running on storage. This article focuses on the analysis feature of iSDS cluster by detailing its architecture and design.
