Highly-available datastores are widely deployed for online applications. However, many online applications are not contented with the simple data access interface currently provided by highly-available datastores. Distributed transaction support is demanded by applications such as largescale online payment used by Alipay or Paypal. Current solutions to distributed transaction can spend more tha...

Extensive research has been carried out in search for an efficient atomic commit protocol and many optimizations have been suggested to improve the two-phase commit protocol, either for the normal or failure case. Yet, the performance effects on transaction processing when combining some of these optimizations have not been studied in depth. In this paper, we concentrate on the flattening-of-th...

In this paper, I will endeavor to interpret the motives that led Anna Karenina commit suicide. They are diverse, starting with public rejection of Ana, her isolation, and experience losing love, all way personal humiliation escapism from evil world. The reasons for suicide interrelated, although they not same significance. both physiological mental-spiritual character, whereby latter contribute...

We examine the n -point matrix probability functions S, (which give the probability of finding n points in the matrix phase of a two-phase random medium), for a model in which the included material consists of fully penetrable spheres of equal diameter (i.e., a system of identical spheres such that their centers are randomly distributed in the matrix). Exploiting the special simplicity of the m...

Distributed database systems require a commit process to preserve the ACID property of transactions executed on a number of system sites. With the appearance of main memory database system, the database processing time has been reduced in the order of magnitude, since the database access does not incur any disk access at all. However, when it comes to distributed main memory database systems, t...

As a historical era, postmodernism signifies transition from inflexible and logical positivism and entry into a new view to science. Postmodernism offers a number of nursing practice revise that including humanism, conditions, and borderless, multi-voice, view, and multicultural world, changes in meaning of knowledge, and life-long learning. Demographic changes, technological advances, ethnic a...

this paper seeks to investigate a new definition for architecture by unifying the three vitruvian principles of firmitas, utilities, and venustas via a phenomenological approach in the interpretation and analysis of their role in defining architecture. the paper is composed in two main sections. the first section investigates the nature of architecture based on the mentioned principles, where a...
