斯拉夫哈萨克文与现行哈萨克文编码字符转换规则的探究

哈萨克语在发展变化的过程中,在世界范围内形成了基于同一语言的两种文字形式的特殊情况,分别是国外的以斯拉夫文字母为基础的哈萨克斯拉夫文字,称之为斯拉夫哈萨克文,以及我国的以阿拉伯文字母为基础的哈萨克阿拉伯文字,称之为现行哈萨克文。由于两种哈萨克文发音相同,而且均是一音一字的文字形式,所以斯拉夫哈萨克文与现行哈萨克文是可以通过规则互相转换的,但至今并没有相关的国家或地方标准对转换规则进行明确描述。因此,本文通过对斯拉夫哈萨克文和现行哈萨克文的研究,提出两种文字的字符编码转换规则。

Mobile Cloud Computing: A Survey,State of Art and Future Directions

In the recent years, cloud computing frameworks such as Amazon Web Services, Google AppEngine and Windows Azure have become increasingly popular among IT organizations and developers. Simultaneously, we have seen a phenomenal increase in the usage and deployment of smartphone platforms and applications worldwide. This paper discusses the current state of the art in the merger of these two popular technologies, that we refer to as Mobile Cloud Computing (MCC). We illustrate the applicability of MCC in various domains including mobile learning, commerce, health/wellness and social medias. We further identify research gaps covering critical aspects of how MCC can be realized and effectively utilized at scale. These include improved resource allocation in the MCC environment through efficient task distribution and offloading, security and privacy.

Optimal nonnegative definite approximations of estimated movingaverage covariance sequences

The problem of finding the closest nonnegative definite moving average covariance sequence to a given estimate which may not be nonnegative definite is considered. An algorithm is developed which is based on a set of constrained minimization problems, each parameterized by the zero frequencies of the spectral density function corresponding to the optimal solution. The algorithm entails first solving a simple minimization problem with linear constraints whose closed-form solution is given by a projection onto a subspace. These solutions lie either outside the set of nonnegative definite sequences, or on its boundary; if the solution lies on the boundary, it is the optimal solution. The problem is considered directly in the space of covariance sequence elements. As a result, the nonlinear maximization step is performed on sets of low dimension. By considering the minimization problem in this space, it is possible to characterize some of the geometrical properties of the optimal solution in terms of the locations of its zero frequencies
