基于C2C的可信信用评价模型

提出一个基于C2C的可信信用评价模型。该模型根据历史交易记录,在综合考虑交易金额、买卖双方信誉度、交易次数、差评次数、未评价交易的基础上,采用动态计算的方式,为交易的成功进行提供可靠的依据。该模型可以有效甄别恶意用户和诚信用户,从而减少信誉诋毁行为,并可减少信誉榨取行为,提高C2C电子交易的安全性。     

浅析C2C在线交易合同的要约与承诺

C2C在线交易合同本质上是买卖合同。该合同的成立要根据C2C的特殊交易模式来具体分析。无论是立刻购买型还是竞价购买型,要约与承诺的认定都离不开《合同法》之根本。     

淘宝C2C网货品牌如何进入B2C

如今淘宝上很多店铺或商品的日销量超过十几万元，具有众多忠诚用户，也拥有一定的知名度和美誉度。但不管在淘宝上的销量有多高，这些商品最多只是C2C网货品牌，而不能成为真正具有，“泛影响力和品牌传播力的市场品牌。也无法像传统品牌那样，与大型B2C开展市场合作。     

C2C信用评价体系的风险计算

目前,C2C电子商务网站纷纷建立了较合理的评价体系,但在交易中仍然存在风险问题。本文通过对C2C模式交易过程的分析,提出了一种根据历史交易的情况,综合考虑卖家的信用值、买家的信用等级以及商品价格等因素的信用风险计算方法。通过模拟实验表明,对目前网上购物的信用炒作起到了一定的防御作用,有助于交易者做出正确的交易决策,为电子商务网站提供了更有效的信用评价信息。

激光打印和LED打印是当今数码打印领域的两大核心技术．二者的不同之处在于光扫描成像过程。目前．普通激光打印技术的光扫描成像过程是将全部数据信号串行传送给一个光发射装置,然后发射出的光线经旋转的多棱镜反射后再成像于感光鼓上。类似于激光打印技术,LED技术的光扫描成像方式则是采用了密集LED阵列为光发射器,数据电信号经LED转化为光信号．并照射到感     

Exceptional C or C with exceptions

C does not have exception handling facilities. Errors are handled by examining the value returned by each function and signals (conditions reported to the program) are handled by using library functions. These approaches lead to ad hoc error-handling techniques and can make programs hard to understand. Exceptional C, a superset of C, provides exception handling facilities. Exceptional C integrates the two techniques used by C programmers (i.e., status values and signals) to handle errors into one unified exception handling mechanism. In this paper, I review exception handling models, specify the criteria used for designing the exception handling facilities in Exceptional C, and then describe these facilities. I also illustrate the use of the exception handling facilities with examples.     

High-fidelity C/C++ code transformation

As software systems become increasingly massive, the advantages of automated transformation tools are clearly evident. These tools allow the machine to both reason about and manipulate high-level source code. They enable off-loading of mundane and laborious programming tasks from human developer to machine, thereby reducing cost and development time frames.Although there has been much work in software transformation, there still exist many hurdles in realizing this technology in a commercial domain. From our own experience, there are two significant problems that must be addressed before transformation technology can be usefully applied in a commercial setting. These are: (1) Avoiding disruption of the style (i.e., layout and commenting) of source code and the introduction of any undesired modifications that can occur as a side effect of the transformation process. (2) Correct automated handling of C preprocessing and the presentation of a semantically correct view of the program during transformation. Many existing automated transformation tools require source to be manually modified so that preprocessing constructs can be parsed. The real semantic of the program remains obscured resulting in the need for complicated analysis during transformation. Many systems also resort to pretty printing to generate transformed programs, which inherently disrupts coding style. In this paper we describe our own C/C++ transformation system, Proteus, that addresses both these issues. It has been tested on millions of lines of commercial C/C++ code and has been shown to meet the stringent criteria laid out by Lucent’s own software developers.

改进C/C++的预处理功能

预处理在C/C 中发挥着重要作用,然而这些预处理功能存在着一些缺陷,例如在头文件包含进来时,无法改变头文件中的内容;代码的重用性不高;大量重复代码等等。本文提出用一种高级配置语言XVCL(XML-basedVariantConfigura-tionLanguage)代替原来的预处理机制,来克服以上提出的问题。文件被组织为树形结构,并定义了利于提高重用性的变量作用域机制。文章通过一个实例来验证本文提出的方法的有效性。     

C2C电子商务企业竞争力研究

伴随着互联网的发展,电子商务逐渐进入我们的经济生活中。作为网络经济的产物,电子商务企业与传统企业在竞争优势上存在巨大差异。面对着日益激烈的竞争,电子商务企业如何保持核心竞争力优势对企业的生存尤为重要。本文聚焦于C2C领域,并以淘宝网为例,尝试从企业核心竞争力的角度诠释电子商务企业与传统企业竞争优势的差异和竞争力培养的着力点。     

C/C++预处理分析与改进

通常的C/C 预处理器是一个宏处理器,在编译前自动地把源文件转换为编译器可识别的形式。传统的预处理方法基于文本行替换,没有考虑到具体的上下文环境。这种预处理机制在文件包含、宏作用域、头文件关系上存在着一些缺陷,会影响工程项目代码重用,降低程序的可维护性、可扩展性等。通过从分析c预处理器缺陷出发,并利用FOG[1]及其语言可以得到一种基于元变量和元函数的语法替换机制的解决方案。
