The prevalence of smart mobile IT industry is changing very rapidly worldwide. Wide varieties of products are linked to the smart mobile and offer various services. Among them, handicapped assistive devices are also growing rapidly and a variety of products have been released. This paper proposes a system that uses a customized cloud-based mobile device to control the wheel chair. Through a simple login, users are able to control a wheelchair that fits on the sheets, personal affront to fit window or by setting the time every hour to prevent system access. The mobile device is not only used to control movement but also in event of problem or error, it can be checked through the smart device interface. If an emergency occurs, a message will be sent to a pre-registered contact. © 2013 IEEE.

In this paper, we propose a deep packet inspection system based on the MapReduce. The MapReduce which is a parallel distributed programming model developed by Google applies the technology of deep packet inspection. Network protocol analysis technique is invoked to realize detect, effectively reducing the packet number to be matched. Furthermore, cache technology is adopted to store attack signature from database in order to reduce the frequency of reading the rules from library file which improved the detection efficiency. Experimental results show that effectiveness of the proposed system with the high-speed network traffic. Copyright © 2013 Binary Information Press.

Abnormal network traffic detection approach based on alive entropy

引用

Tongxin Xuebao/Journal on Communications 2013年第SUPPL.2期34卷 51-57页

作者： Mu, Xiang-Kun Wang, Jin-Song Xue, Yu-Feng Huang, Wei Tianjin Key Lab. of Intelligent Computing and Novel Software Technology Tianjin University of Technology Tianjin 300384 China Key Laboratory of Computer Vision and System Ministry of Education Tianjin University of Technology Tianjin 300384 China

A novel alive entropy-based detection approach was proposed, which detects the abnormal network traffic based on the values of alive entropies. The alive entropies calculated based on the NetFlow data coming from the network traffic of input and output of a whole system, which is essentially a monitored network. In order to decrease false positive rate of abnormal network traffic, different scales are selected to compute the values of alive entropies in different sizes of network traffic. With the low false positive rate of abnormal network traffic, the abnormal network traffic can be effectively detected. Experiments carried out on a real campus network were used to evaluate the effectiveness of the proposed approach. A comparative study illustrates that the proposed approach may easily detect the abnormal network traffic with random characteristics in comparison with some "conventional" approaches reported in the literatures.

Object grasping is commonly followed by some form of object manipulation - either when using the grasped object as a tool or actively changing its position in the hand through in-hand manipulation to afford further interaction. In this process, slippage may occur due to inappropriate contact forces, various types of noise and/or due to the unexpected interaction or collision with the environment. In this paper, we study the problem of identifying continuous bounds on the forces and torques that can be applied on a grasped object before slippage occurs. We model the problem as kinesthetic rather than cutaneous learning given that the measurements originate from a wrist mounted force-torque sensor. Given the continuous output, this regression problem is solved using a Gaussian Process approach. We demonstrate a dual armed humanoid robot that can autonomously learn force and torque bounds and use these to execute actions on objects such as sliding and pushing. We show that the model can be used not only for the detection of maximum allowable forces and torques but also for potentially identifying what types of tasks, denoted as manipulation affordances, a specific grasp configuration allows. The latter can then be used to either avoid specific motions or as a simple step of achieving in-hand manipulation of objects through interaction with the environment.

This paper introduces a method for estimating the constraints imposed by a human agent on a jointly manipulated object. These estimates can be used to infer knowledge of where the human is grasping an object, enabling the robot to plan trajectories for manipulating the object while subject to the constraints. We describe the method in detail, motivate its validity theoretically, and demonstrate its use in co-manipulation tasks with a real robot.

As the smartphone market grows, tracking a person's own positions become easier and popular. Especially for the bicycling, file based GPS data make it easier to manage and access personal trajectories. In this paper, we propose an effective color coding method for massive bicycle trajectories visualization. The motivation of the method is based on characteristics of the bicycle trajectories which have different spatial aspects compare to the automobiles. The proposed method modifies the color of the line segments based on the direction and flow, and provides visually enhanced trajectories. GPS data collected from Han riverside bicycle tracks were applied to the proposed visualization methods, and shown the potential possibilities for trajectory analysis. © 2013 Springer Science+Business media.

A contents authoring software with device management for interactive shows and performances is proposed. The proposed system allows user to register and to manage various stage-related devices such as lighting system, fog generator, robots or multimedia players. In this paper, we describe software architecture, XML specification for unified protocol description, and user interface of the proposed system. The system can control multiple devices of heterogeneous protocols in timely manner. Once devices are registered, user can browse commands of each device and can organize commands to step-based list according to the performance scenario. Unlike current commercialized products, the system allows to manipulate authored list of commands during the show instantly. The proposed system also supports to control playback of authored commands by sensor inputs so that a player can trigger devices to execute according to events. The contributions of this paper can be summarized to three points;(1) define unified protocol description with XML structures for simplicity (2) give sensor triggering capability to control devices, and (3) implement fast and instant manipulation user interface during the show. © 2013 Springer Science+Business media.

The combination of advanced genomic technologies and computational tools enables researchers to conduct large-scale experiments that answer biological questions in unprecedented ways. However, interaction tools in this area currently remain immature. We propose that tangible, embedded, and embodied interaction (TEI) offers unique opportunities for enhancing discovery and learning in genomics. Also, designing for problems in genomics can help move forward the theory and practice of TEI. We present challenges and key questions for TEI research in genomics, lessons learned from three case studies, and potential areas of focus for TEI research and design. Copyright 2013 ACM.

Finding a parking place in a busy city centre is often a frustrating task for many drivers;time and fuel are wasted in the quest for a vacant spot and traffic in the area increases due to the slow moving vehicles circling around. In this paper, we present the results of a survey on the needs of drivers from parking infrastructures from a smart services perspective. As smart parking systems are becoming a necessity in today's urban areas, we discuss the latest trends in parking availab.lity monitoring, parking reservation and dynamic pricing schemes. We also examine how these schemes can be integrated forming technologically advanced parking infrastructures whose aim is to benefit both the drivers and the parking operators alike.
