In this paper, an handwritten character recognition system based on acceleration is presented. The character recognition system using a 3-dimensional (3D) accelerometer, includes three procedures: original signal detection, signal processing (preprocessing and quantization) and recognition/classification. In quantization procedure, Trajectory Orientation (TO) and Curve Feature (CF) are adopted and compared. In recognition procedure, Fully-connected Hidden Markov Model (HMM) and Left-Right HMM are both implemented and compared. The system, in the recognition of 10 Arabic numerals, achieves the Correct Rate(CR) of 99.05% and the Total Correct Rate (TCR) of 94.76%. © 2011 AICIT.

Distributed systems commonly replicate data to enhance system dependability. In such systems, a logical update on a data item results in a physical update on a number of copies. The synchronization and communication required to keep the copies of replicated data consistent introduces a delay when operations are performed. In time-constrained systems or systems distributed over a bandwidth-constrained area, such operational delays generally prove unacceptable. Asynchronous data replication is commonly used to mitigate these delays. We look to develop a general solution for the introduction of an adaptive data replication scheduler to optimize asynchronous replications based on a user-developed priority model in overloaded situations. The solution uses a Multi-Layer Perceptron neural network to mimic the behavior of a historically optimal scheduler through functional approximation with its evaluation through simulation. © 2005 IEEE.

Enterprise Architecture (EA) models help enterprise architects to make business decisions and to support organisations to understand and analyse its structure. Creating and maintaining such an EA model is expensive and time-consuming in large organisations. In this paper, the authors provide a review of how graph analytic methods can be used to support EA model maintenance. To achieve the best results for the duplicate identification, it is necessary to evaluate and optimise different graph analytic and Machine Learning (ML) algorithms to support the maintenance process.

SURVEY OF DYNAMIC TAINT ANALYSIS

SURVEY OF DYNAMIC TAINT ANALYSIS

引用

2014 4th IEEE International Conference on Network Infrastructure and Digital Content

作者： Junhyoung Kim Tae Guen Kim Eul Gyu Im Department of Computer and Software Hanyang University Division of Computer Science and Engineering Hanyang University

Dynamic taint analysis（DTA） is to analyze execution paths that an attacker may use to exploit a system. Dynamic taint analysis is a method to analyze executable files by tracing information flow without source code. DTA marks certain inputs to program as tainted, and then propagates values operated with tainted inputs. Due to the increased popularity of dynamic taint analysis, there have been a few recent research approaches to provide a generalized tainting infrastructure. In this paper, we introduce some approaches of dynamic taint analysis, and analyze their approaches. Lam and Chiueh’s approach proposed a method that instruments code to perform taint marking and propagation. DYTAN considers three dimensions: taint source, propagation policies, taint sink. These dimensions make DYTAN to be more general framework for dynamic taint analysis. DTA++ proposes an idea to vanilla dynamic taint analysis that propagates additional taints along with targeted control dependencies. Control dependency causes results of taint analysis to have decreased accuracies. To improve accuracies, DTA++ showed that data transformation containing implicit flows should propagate properly to avoid under-tainting.

Foraging Behavior in Ant Swarms can be very helpful when applied to the protocols in Mobile Ad hoc NETworks (MANETs). When the Ant Colony Optimization Scheme (ACO) is applied to a protocol, larger number of paths are generated from the source to destination which helps in improving the packet delivery ratio because an alternate back up path is always available in case a path gets broken due to the mobile nodes. In this paper, we apply the ACO scheme on an already existing Energy efficient protocol Conditional Max-Min Battery Capacity Routing (CMMBCR) (C.-K. Toh, 2001). The CMMBCR not only takes care of the total transmission energy in the network but also the residual battery capacity of the nodes. Hence applying ACO scheme on CMMBCR makes it more efficient in terms of energy, packet delivery ratio etc. The efficiency of our proposed protocol A-CMMBCR is then established by comparing it with some of the other existing Energy aware protocols such as Energy-Aware Routing protocol (EAAR) (Dhurandher et al., 2009), Minimum Transmission Power Routing (MTPR) (Scott and Bambos, 1996) and CMMBCR. The results are captured in the form of a graphical format.

Wearable computer can be worn anytime with the support of unrestricted communications and variety of services which provides maximum capability of information use. Key challenges in developing such wearable computers are level of comfort that users do not feel what they wear, easy and intuitive user interface and power management technique. This paper suggests a wearable system that consists of a wristwatch-type gesture recognition device and a personal mobile gateway that functional input/output modules can be freely plugged in and taken out. We describe our techniques implemented during our wearable system development: 1) multimodal fusion engine that recognizes voice and gesture simultaneously, 2) power management technique and 3) gesture recognition engine. Finally, we evaluate the performance of our multimodal fusion engine, and show the power consumption measurement data of our system built with the power management technique. © Springer-Verlag Berlin Heidelberg 2007.

Modern software-defined radios are large, expensive, and power-hungry devices and this, we argue, hampers their more widespread deployment and use, particularly in low-power, size-constrained application settings like mobile phones and sensor networks. To rectify this problem, we propose to put the software-defined radio on a diet by redesigning it around just two core chips - an integrated RF transceiver and a Flash-based, mixed-signal FPGA. Modern transceivers integrate almost all RF front-end functions while emerging FPGAs integrate nearly all of required signal conditioning and processing functions. And, unlike conventional FPGAs, Flash-based FPGAs offer sleep mode power draws measured in the microamps and startup times measured in the microseconds, both of which are critical for low-power operation. If our platform architecture vision is realized, it will be possible to hold a software-defined radio in the palm of one's hand, build it for $100, and power it for days using the energy in a typical mobile phone battery. This will make software radios deployable in high densities and broadly accessible for research and education. © 2010 ACM.
