Authors: Yizhen Liu, Daxiong Xu, Dong Liu, Lingge Sun
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

The current hardware architectures of intrusion detection system have several limitations on performance and configurability. In this paper we describe the architecture design and hardware implementation of gigabits NIDS using a programmable network processor and a FPGA co-processor. We discuss the requirements of NIDS, system hardware architecture and report measurements. In particular, we demonstrate performance improved by optimized parallel pattern match processing and efficient memory access in Field Programmable Gate Array (FPGA). We show an NIDS which can exploit our approach hardware platform, and make suggestions about implementation features that can significantly improve the performance and configurability of intrusion detection systems.
Detecting Threats in Star Graphs
Authors: Navid Imani, Hamid Sarbazi-Azad, Albert Y. Zomaya, Parya Moinzadeh
Venue: IEEE Transactions on Parallel and Distributed Systems (2009)

In this paper, we consider the problem of searching a network for intruders. We propose a strategy for capturing the intruder in the popular interconnection topology, the star network. According to the proposed strategy, a team of collaborative software agents are responsible for capturing a hostile intruder (e.g. a virus). These agents asynchronously move along the network links and the intruder has the capability of escaping arbitrarily fast.
A new method for ranking discovered rules from data mining by DEA
Authors: Mehdi Toloo, Babak Sohrabi, Soroosh Nalchigar
Venue: Expert Systems with Applications: An International Journal (2009)

Data mining techniques, extracting patterns from large databases have become widespread in business. Using these techniques, various rules may be obtained and only a small number of these rules may be selected for implementation due, at least in part, to limitations of budget and resources. Evaluating and ranking the interestingness or usefulness of association rules is important in data mining. This paper proposes a new integrated data envelopment analysis (DEA) model which is able to find most efficient association rule by solving only one mixed integer linear programming (MILP). Then, utilizing this model, a new method for prioritizing association rules by considering multiple criteria is proposed. As an advantage, the proposed method is computationally more efficient than previous works. Using an example of market basket analysis, applicability of our DEA based method for measuring the efficiency of association rules with multiple criteria is illustrated.

Authors: Shervin Vakili, S. Mehdi Fakhraie, Siamak Mohammadi, Ali Ahmadi
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 02 (2009)

Decomposition and scheduling are two major challenges in hardware and software developments of multi&not;processor systems. The introduced EvoMP (Evolvable Multi-Processor) is a novel NoC-based homogeneous MPSoC system that performs decomposition and scheduling using evolutionary algorithms at run-time. A hardware genetic core was used in first version of this platform to perform these two tasks. This core tries to find an efficient solution for decomposition and scheduling of the target application among available computational resources. This paper presents the new version of this system in which a hardware Particle Swarm Optimization (PSO) core is exploited to perform evolutionary decomposition and scheduling. The principle of operation and architecture of the EvoMP platform and the PSO core is briefly explained in this paper. The simulation and synthesis results of this PSO-based EvoMP is also presented and compared with prior genetic-base approach.

Game-Theoretic Security Analysis of Quantum Networks
Authors: Stefan Rass, Peter Schartner
Venue: Proceedings of the 2009 Third International Conference on Quantum, Nano and Micro Technologies (2009)

Unconditional security is the key-feature of quantum cryptography, which makes it superior to any classical encryption scheme. Most research in this area focuses on analyzing the theoretical properties and performance of particular quantum key distribution protocols, but a rigorous analysis on the network level seems to be missing. We present a game-theoretic approach which gives simple and tight bounds to the risk of communication that any two peers in a quantum network have to take when communicating, even if quantum cryptography is used. This work is motivated by recent (im)possibility results regarding unconditionally secure message transmission in arbitrary networks, which puts stringent constraints on the network topology. Hence, our model naturally accounts for a given graph topology (existing fibre-optic networks which are natural candidates for a roll-out of a quantum network), as well as measuring risk in terms of probability or the designers subjective understanding. As a by-product, our model gives optimal path selection strategies, and the optimal design of network topologies under given constraints (like geographic or monetary ones).
Derivation and use of a survivability criterion for DDP systems
Authors: Richard E. Merwin, Mohammed Mirhakak
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

With the advent of low cost compact computing systems, there has been a natural tendency to bring the computer to the job rather than the job to the computer. The geographical distribution of computing also leads to a necessity to interconnect installations so that they can share data, provide back up computing support, and permit rapid transfer of messages between sites. We are now seeing the emergence (1, 2) of networks of computers interconnected by communication facilities. There are numerous benefits to be achieved by this dispersal of computing facilities including more reliable overall operational capability, better overall service to geographically separated sites, and the advantages of being able to utilize a wide range of software and hardware facilities available through telecommunication systems.
A New Controller Controlling the Synchronous Communication between Different Chua's Circuits
Authors: Hong Chen, Qun Ding
Venue: Proceedings of the 2009 International Asia Conference on Informatics in Control, Automation and Robotics (2009)

A new controller is presented for the chaotic synchronization and secure communication problems of two Chua’s systems in application. The method of forming controller is given in the paper. And it is analysed and proved by using Lyapunov stability theory that the new controller can control the error of two different Chua’s chaotic systems to be asymptotically stabile. Finally under the control of controller, a lot of computer simulation experiments are done by using Matlab for the synchronous communications between the different structure Chua’s systems, and between the different state Chua’s systems and so on. The simulation results demonstrate the effectiveness of the controller.
Exploiting Positive and Negative Graded Relevance Assessments for Content Recommendation
Authors: Maarten Clements, Arjen P. Vries, Marcel J. Reinders
Venue: Proceedings of the 6th International Workshop on Algorithms and Models for the Web-Graph (2009)

Social media allow users to give their opinion about the available content by assigning a rating. Collaborative filtering approaches to predict recommendations based on these graded relevance assessments are hampered by the sparseness of the data. This sparseness problem can be overcome with graph-based models, but current methods are not able to deal with negative relevance assessments.We propose a new graph-based model that exploits both positive and negative preference data. Hereto, we combine in a single content ranking the results from two graphs, one based on positive and the other based on negative preference information. The resulting ranking contains less false positives than a ranking based on positive information alone. Low ratings however appear to have a predictive value for relevant content. Discounting the negative information therefore does not only remove the irrelevant content from the top of the ranking, but also reduces the recall of relevant documents.
Parameters Extraction for Pseudomorphic HEMTs Using Genetic Algorithms
Authors: Mazhar B. Tayel, Amr Hassan Yassin
Venue: Proceedings of the 2009 International Conference on Electronic Computer Technology (2009)

A proposed small-signal model parameters for a pseudomorphic high electron mobility transistor (PHEMT) is presented. Both extrinsic and intrinsic circuit elements of a small-signal model are determined using genetic algorithm (GA) as a stochastic global search and optimization tool. The parameters extraction of the small-signal model is performed on 200-μm gate width AlGaAs/InGaAs PHEMT. The equivalent circuit elements for a proposed 18 elements model are determined directly from the measured S- parameters. The GA is used to extract the parameters of the proposed small-signal model from 0.5 up to 18 GHz.

Arnoldi-Tikhonov regularization methods
Authors: Bryan Lewis, Lothar Reichel
Venue: Journal of Computational and Applied Mathematics (2009)

Tikhonov regularization for large-scale linear ill-posed problems is commonly implemented by determining a partial Lanczos bidiagonalization of the matrix of the given system of equations. This paper explores the possibility of instead computing a partial Arnoldi decomposition of the given matrix. Computed examples illustrate that this approach may require fewer matrix-vector product evaluations and, therefore, less arithmetic work. Moreover, the proposed range-restricted Arnoldi-Tikhonov regularization method does not require the adjoint matrix and, hence, is convenient to use for problems for which the adjoint is difficult to evaluate.
A novel open CNC architecture based on STEP-NC data model and IEC 61499 function blocks
Authors: M. Minhat, V. Vyatkin, X. Xu, S. Wong, Z. Al-Bayaa
Venue: Robotics and Computer-Integrated Manufacturing (2009)

Modern manufacturing industries demand computer numeric controllers, having higher level input languages than outdated G-code, and less proprietary vendor dependencies. IEC 61499 is a new standard for distributed measurement and control systems, that enables portability and interoperability of embedded controllers, along with the ease of their mapping to arbitrary distributed networking hardware configurations. This paper demonstrates that the IEC 61499 reference architecture can be successfully used to create a computer numeric controller, offering interoperability, portability, configurability, and distribution characteristics. The layered CNC-FB architecture is proposed, which simplifies the design of a CNC machine controller with the architecture layers responsible for data processing, data storage and execution. In combination with the object-oriented Model-View-Control design pattern, the CNC-FB architecture supports the design framework, in which simulation of the machining becomes natural and inherent part of the design process, with seamless transition from simulation to actual machining. The implemented controller was tested in both the model and on an actual milling machine.
Price aggregation in an end-to-end QoS provisioning
Authors: Toma Turk
Venue: Computer Standards Interfaces (2009)

In this paper we are focusing on the possibility that information about end users' willingness to pay for data transfer in the end-to-end manner is propagated through the communication network to achieve certain level of QoS. We propose a scheme where price information is propagated along the network path, where each network resource subtracts its share of value from packet's price. The proposed scheme establishes a direct relationship between expressed willingness to pay and gained QoS level. The scheme could be further developed and implemented with compliancy to QoS standards, like Differentiated and Integrated Services.
A high-performance FPGA architecture for restricted boltzmann machines
Authors: Daniel L. Ly, Paul Chow
Venue: Proceeding of the ACM/SIGDA international symposium on Field programmable gate arrays (2009)

Despite the popularity and success of neural networks in research, the number of resulting commercial or industrial applications have been limited. A primary cause of this lack of adoption is due to the fact that neural networks are usually implemented as software running on general-purpose processors. Algorithms to implement a neural network in software are typically O(n2) problems -- as a result, neural networks are unable to provide the performance and scalability required in non-academic settings. In this paper, we investigate how FPGAs can be used to take advantage of the inherent parallelism in neural networks to provide a better implementation in terms of scalability and performance. We will focus on the Restricted Boltzmann machine, a popular type of neural network, because its architecture is particularly well-suited to hardware designs. The proposed, multi-purpose hardware framework is designed to reduce the O(n22) problem into an O(n) implementation while only requiring O(n) resources. The framework is tested on a Xilinx Virtex II-Pro XC2VP70 FPGA running at 100MHz. The resources support a Restricted Boltzmann machine of 128x128 nodes, which results in a computational speed of 1.02 billion connection-updates-per-second and a speed-up of 35 fold over an optimized C program running on a 2.8GHz Intel processor.

Authors: H. Kurdi, M. Li, H. S. Al-Raweshidy
Venue: Proceedings of the 2008 The Second International Conference on Next Generation Mobile Applications, Services, and Technologies (2008)

As mobile personal devices have become more powerful, being used across different environments, there is a need to further enable these devices to seamlessly share resources such as processing power, storage capacity and functionality in the form of services available across a global network environment such as the computational grid. This paper aims to present a generic framework for self-organized and adaptive scheduling in a grid environment built on personal mobile devices i.e. a Personal Mobile Grid (PM-Grid). The proposed scheduling framework (HoPe), which is inspired by honeybee food collection techniques, shows a considerable enhancement in service turnaround time and throughput over the traditional opportunistic scheduling heuristic. Consequently, we claim that the proposed scheduling framework can benefit applications in grid environments.
Traffic Assignment Model Considering Emission Based on Path-based Solution Algorithm: Comparison and Discussion
Authors: Ming-Wang Dong, Wei Xiong
Venue: Proceedings of the 2009 International Conference on Computer Modeling and Simulation (2009)

In this paper, we discuss a nonadditive path costs traffic assignment problem considering emission effects. Based on Venigalla's research, we put forward the traffic assignment model considering emissions at different engine operating modes. We also use two path-based algorithms, gradient projection (GP) algorithm and disaggregated simplicial decomposition (DSD) algorithm to solve the mathematic model respectively. Then, we apply the model as well as the algorithms into a real network and compare some computational characteristics of them. The results show that both GP and DSD algorithms have a rapid convergence speed than FW algorithm. The results also demonstrate that path-based algorithms can be widely used in solving large scale traffic assignment problem with nonadditive path costs.
