Title: Tracking On-line Radicalization Using Investigative Data Mining
Authors: Pooja Wadhwa, MPS Bhatia
Abstract: The increasing complexity and emergence of Web 2.0 applications have paved way for threats arising out of the use of social networks by cyber extremists (Radical groups). Radicalization (also called cyber extremism and cyber hate propaganda) is a growing concern to the society and also of great pertinence to governments & law enforcement agencies all across the world. Further, the dynamism of these groups adds another level of complexity in the domain, as with time, one may witness a change in members of the group and hence has motivated many researchers towards this field. This proposal presents an investigative data mining approach for detecting the dynamic behavior of these radical groups in online social networks by textual analysis of the messages posted by the members of these groups along with the application of techniques used in social network analysis. Some of the preliminary results obtained through partial implementation of the approach are also discussed.

Title: Secret Sharing Scheme Suitable for Cloud Computing
Authors: Satoshi Takahashi Keiichi Iwamura
Abstract: Secret sharing schemes have recently been considered to apply for cloud computing in which many users distribute multiple data to servers. However, when Shamir s(k,n) secret sharing is applied to cloud systems, the amount of share increases more than n times the amount of the secret. Therefore, in this paper we propose a new secret sharing scheme that can reduce the amount of share different from Ramp type secret sharing, suitable for cloud systems, and we prove that it is computationally secure.

Title: Solution blown nanofibrous membrane for microfiltration
Authors: Xupin Zhuang a,b , Lei Shi a , Kaifei Jia a , Bowen Cheng b,n , Weimin Kang
Abstract: Nanofibrous membranes have been paid attention in microfiltration. Solution blowing process is a new nanofiber fabricating method with high productivity. In this study, polyvinylidene fiuoride (PVDF) nanofibrous mat was successfully solution blown using a multiorifices die. The fibers were mostly 60 280 nm in diameter and three-dimensional curly which resulted in a loose construction with high porosity of 95.8%. The nanofibrous mat was further hot-pressed to increase its integrality. The structure and microfiltration performance was evaluated. The results showed the crystallinity of the membranes increased, the porosity and pore size decreased after hot-pressing treatment. The hot-pressed membranes showed high retention ratio against microparticles and high pure water fiux which will help the solution blown membrane find application in high fiux microfiltration.

Title: Traffic Information Based Power Saving Mechanism
Authors: Ju No Han, Seong Gon Choi
Abstract: This paper proposes the standby power saving mechanism that the user can terminate home network appliance (Le. Personal Computer) power and standby power at the remote site. Generally, for the power management of the home appliance, it has to be put through the physical contact. In the proposed mechanism, the smartphone is offered the power on/off state information of the home network appliance on a real-time basis. The user can transmit the power-termination order to the home network appliance through the smartphone. If the home gateway receives the power-termination order from the smartphone, the power-termination order is sent to the home network appliance and the standby power is blocked. Its power and standby power can be blocked through the method to be proposed even through the user is not physically contacted with the home appliance. That is, the proposed mechanism gives convenience to the user in electric power management aspect. In addition, the power saving can be done, because reducing the unnecessary operation time and blocking the standby power of the home network appliance.

Title: Design for rebirth (DFRb) and data structure
Author: Christian Mascle
Abstract: In this paper, rebirth, the methodology of design for rebirth antedate structure which it requires will be examined. Rebirth is a global strategy of product analysis for sustainable development. A methodology is developed to conceive a product according to objectives defined by its end of life and its generic engineering requirements, and this methodology is implanted in a framework. Our data structure is based on topological information from a boundary representation (B-rep) model and it processes all information relative to the life cycle of the product. The software, based on this data structure, allows predefining certain characteristics based on knowledge of the company or on the data base. This facilitates its use for a wide range of applications.
