Online social gaming is an emerging Internet application that combines online gaming and online social networking functionality for the benefit of millions of daily users. While researchers have investigated the structure of (social) networks for decades, the activity characteristics and the community structure of online social gaming remain relatively unknown. To address this situation, in this work we investigate the BBO Fans club for online bridge. First, we introduce a method to collect and analyze data from BBO Fans and its underlying gaming platform. Our method is novel in that it addresses the lack of a strict definition of social relationship between BBO Fans players, and it defines several player types with implications on community formation and operation. Second, we use the proposed method to collect and analyze a 40-day BBO Fans dataset comprising over 140,000 unique players and over 3,000,000 unique play sessions. T hird, we compare the characteristics of BBO Fans with other large social networking and online gaming applications. We find in particular that BBO Fans generates similar levels of activity as but has different community characteristics than similarly-sized games on FaceBook, the largest social network in the world.

This paper presents a practical implementation of a custom wireless access point with display module to view the communication and configuration parameters. For the display module we design a hierarchy menu system, with control buttons that enable the user to scroll to specific types of information and select between parameters. The display module is very useful for embedded systems with limited resources because it offers status information about connected users, ROMIRAM usage, IP address, connection types, transfer rates, bandwidth, etc. without the need to enter the configuration menu using web interface.
When analyzing the Radio Frequency Identification applications, one might think of two essential hierarchies: the structures aiming to offer security to an RFID system and the structures aiming to offer functionality ...

Abstract This paper suggests a new stability analysis theorem dedicated to a class of fuzzy logic control systems. The fuzzy logic control systems consist of nonlinear Single Input-Single Output (SISO) discrete-time processes controlled by Takagi-Sugeno fuzzy logic controllers. The stability analysis is conducted on the basis of Lyapunov's direct method with quadratic Lyapunov function candidates. The theorem proves that if the derivative of the Lyapunov function candidate is negative definite in the active region of each fuzzy rule then the fuzzy logic control system will be asymptotically stable in the sense of Lyapunov. Sufficient stability conditions are offered. An example related to the design of a stable fuzzy logic control system for the discrete-time Lorenz chaotic system and simulation results are included.
There are several research directions in Software Performance engineering (SPE), covering the entire performance prediction process, but most of the tools developed so far implement only part of it or have restriction...
