XML Schema-based Minification for Communication of Security Information and Event Management (SIEM) Systems in Cloud Environments
XML-based communication governs most of today's systems communication, due to
its capability of representing complex structural and hierarchical data.
However, XML document structure is considered a huge and bulky data that can be
reduced to minimize bandwidth usage, transmission time, and maximize
performance. This contributes to a more efficient and utilized resource usage.
In cloud environments, this affects the amount of money the consumer pays.
Several techniques are used to achieve this goal. This paper discusses these
techniques and proposes a new XML Schema-based Minification technique. The
proposed technique works on XML Structure reduction using minification. The
proposed technique provides a separation between the meaningful names and the
underlying minified names, which enhances software/code readability. This
technique is applied to Intrusion Detection Message Exchange Format (IDMEF)
messages, as part of Security Information and Event Management (SIEM) system
communication hosted on Microsoft Azure Cloud. Test results show message size
reduction ranging from 8.15% to 50.34% in the raw message, without using
time-consuming compression techniques. Adding GZip compression to the proposed
technique produces 66.1% shorter message size compared to original XML
messages.Comment: XML, JSON, Minification, XML Schema, Cloud, Log, Communication,

Facial expressions emotional recognition with NAO robot
Human-robot interaction research is diverse and covers a wide range of topics. All aspects of human factors and robotics are within the purview of HRI research so far as they provide insight into how to improve our understanding in developing effective tools, protocols, and systems to enhance HRI. For example, a significant research effort is being devoted to designing human-robot interface that makes it easier for the people to interact with robots. HRI is an extremely active research field where new and important work is being published at a fast pace.
It is crucial for humanoid robots to understand the emotions of people for efficient human robot interaction. Initially, the robot detects human face by Viola- Jones technique. Later, facial distance measurements are accumulated by geometric based facial distance measurement method. Then facial action coding system is used to detect movements of measured facial points. Finally, measured facial movements are evaluated to get instant emotional properties of human face in this research; it has been specifically applied to NAO humanoid robot
