Title: Integration of Face Recognition and Sound Localization for a Smart Door Phone System
Authors: Taewan Kim, Hyungsoo Park, and Yunmo Chung
Abstract: This paper proposes a smart system using both face recognition and sound localization techniques to identify the faces of visitors from a door phone in much efficient and accurate ways. This system is effectively used to recognize the faces when their locations are out of the boundaries of the camera scope of the door phone. The smart door phone system proposed in this paper uses a visitor’s voice source to rotate the camera to his face and then to recognize the face accurately. The integrated system has been designed with one FPGA(Field Programmable Gate Array) chip and tested for actual use in door phone environments.

Title: Design of a Mastering System for Digital Cinema
Authors: Yeonjeong Jeong, Bumho Kim, Kisong Y oon
Abstract: Digital Cinema Initiatives released a set of technical specifications and requirements for Digital Cinema. The mastering system of digital cinema produces the Digital Cinema Package (DCP) which has been designed to deliver digital cinema contents such as image, audio and subtitle between Digital Cinema content processing centers. We propose a mastering system that covers the packaging process of DCP for Digital Cinema content and protection of it.

Title: Adaptive Control for an HVDC Transmission Link with FACTS and a Wind Farm
Authors: Yufei Tang, Haibo He, Senior Member, IEEE, and Jinyu Wen, Member, IEEE
Abstract: Due to the nonlinearity, uncertainty and complex-ity of the power system, it is a challenging task to design aneffective control approach based on the exact model using tradi-tional methods. In this paper, we investigate the application of anovel approximate dynamic programming (ADP) architecture,goal representation heuristic dynamic programming (GrHDP),to a large benchmark power system. Unlike traditional ADPdesign with an action network and a critic network, GrHDPintegrates the third network, a goal network, into the actor-critic design (ACD) to automatically and adaptively build an in-ternal reinforcement signal representation to facilitate learningand optimization. Then the GrHDP is employed to control thebenchmark power system including a DFIG based wind farmand a STATCOM with HVDC transmission. Various powersystem states, including the voltage of STATCOM, current ofDFIG and DC current of HVDC inverter, are provided to theGrHDP controller to generate three adaptive supplementarycontrol signals. These adaptive supplementary control signalsare then provided to the STATCOM controller, DFIG rotor sidecontroller and HVDC master control, respectively. This controlstructure is validated in Matlab/Simulink to demonstrate itseffectiveness in power system control.

Title: Augmenting the World using Semantic Web Technologies
Authors: Jens Grubert, Lyndon Nixon, Gerhard Reitmayr
Abstract: Creating and maintaining augmented scenes for mobile Augmented Reality browsers can be a challenging and time consuming task. The timeliness of digital information artifacts connected to changing urban environments require authors to constantly update the structural representations of augmented scenes or to accept that the information will soon be outdated. We present an approach for retrieving multimedia content and relevant web services for mobile Augmented Reality applications at runtime. Using semantic web technologies we are able to postpone the retrieval of actual media items to the moment a user actually perceives an augmented scene. This allows content creators to augment a scene only once and avoid continuous manual updates. We also discuss the tradeoff between runtime content retrieval using Linked Data concepts and decreased control over the scene appearance at the time of authoring that comes along with this approach.

Title: A Survey of Ant Colony Optimization-Based Approaches to Routing in Computer Networks
Authors: Peter Janacik Dalimir Orfanus Adrian Wilke
Abstract: Nature has provided an elegant solution for the routing problem millions of years ago, when ant colonies started to use swarm intelligence to discover food and route it reliably to their formicaries. The approach utilized by ants has several advantages that are also useful in computer networks: complete distribution, load balancing finding shortest paths with a high probability. Several routing protocols designed for the area of computer networks have made use of this approach, called ant colony optimization. This paper provides first a broad overview of ant colony optimization-based routing protocols, while focusing on four selected approaches in later sections, describing their operation and discussing their properties in detail.
