Designing and Implementing a Distributed Social Network Service for Mobile Devices
The paper presents a new paradigm for building social network services. The proposed plat-form is called eXtensible Social Network. As it uses the XMPP protocol for authentication and communication, it allows users from different service providers interact with each other, without having to change their accounts. Moreover, the platform provides means for users to authenticate and interact with each other while temporary disconnected from the Internet. Moreover, the platform is specially designed for mobile devices, running on their restrictive operating systems and taking advantage of the systems optimizations.Social Network, Mobile Devices, Service, XMPP, iOS, Android, Distributed, Plat-form
Latter research on Euler-Mascheroni constant
In this work, we present a review and an example on some latter results on
the problem of approximating the Euler-Mascheroni constant. We use the method
firstly introduced in [C. Mortici, Product Approximations via Asymptotic
Integration Amer. Math. Monthly 117 (5) (2010) 434-441].Comment: 8 page
The Necessity to Introduce the Accounting Rules and Fair Value in the Conceptual Framework
AbstractIn this paper, I present the fact that important organisations, such as FASB in the United States of America and IASC accept the accounting model of evaluation at fair value which substitutes the historical cost model. Supporters of innovation find the principles, tenets and conventions of any kind, in a way not only to adapt better to the reality, but also to anticipate developments. Although we do not provide evidences as the model for the initial and future evaluations of assets and liabilities (financial and/or non-financial) company, the fair value is the measure of evaluation the most relevant because the trades made on the day of their development reflect the reality of the moment and all the tools that need to be negotiated quickly by the company determine the getting a quick gain. The acceptance of the fair value by all potential users should be subject to a prior agreement
An Algorithm for File Transfer Scheduling in Grid Environments
This paper addresses the data transfer scheduling problem for Grid
environments, presenting a centralized scheduler developed with dynamic and
adaptive features. The algorithm offers a reservation system for user transfer
requests that allocates them transfer times and bandwidth, according to the
network topology and the constraints the user specified for the requests. This
paper presents the projects related to the data transfer field, the design of
the framework for which the scheduler was built, the main features of the
scheduler, the steps for transfer requests rescheduling and two tests that
illustrate the system's behavior for different types of transfer requests.Comment: Proceedings of the International Workshop on High Performance Grid
