Authors: Yongquan Xia, Lihui Cheng, Weili Li, Shaohui Ning
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 02 (2009)

It is important to extract ROI (Region of Interest) based on vision image processing in intelligent transportation system. A simple and novel approach is proposed to extract the RIO in transportation scene images. Firstly, a simple method is used to preprocess the input images; Secondly, interest pixels extraction function is defined to detect all the interest pixels from scene image using adaptive threshold mechanism; after that, these interest pixels connective each other are grouped to interest regions, the non-interest pixels enclosed by interest region are filled as interest pixels; Lastly, the regions selecting using region area threshold are as the extraction result of RIO. The experiment result is presented in the last part of the paper and the proposed approach is feasible and valid.
The Complexity of Andersen's Analysis in Practice
Authors: Manu Sridharan, Stephen J. Fink
Venue: Proceedings of the 16th International Symposium on Static Analysis (2009)

While the tightest proven worst-case complexity for Andersen's points-to analysis is nearly cubic, the analysis seems to scale better on real-world codes. We examine algorithmic factors that help account for this gap. In particular, we show that a simple algorithm can compute Andersen's analysis in worst-case quadratic time as long as the input program is k-sparse, i.e. it has at most k statements dereferencing each variable and a sparse flow graph. We then argue that for strongly-typed languages like Java, typical structure makes programs likely to be k-sparse, and we give empirical measurements across a suite of Java programs that confirm this hypothesis. We also discuss how various standard implementation techniques yield further constant-factor speedups.

Authors: Wei Su, Li-jun Xue, Ying Liu
Venue: Proceedings of the 2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009) (2009)

This paper explains in detail two methods of developing software gateways of fire fighting subsystem running on based on an integration project of intelligent building system completed by the author recently. One method is to use the Agent which is developed based on AI Agent theory and runs between EBI and MK7022. This Agent can be used as the software gateways of fire fighting subsystem and integrate the fire fighting subsystem into BMS “module parallel integration model”. Another method is to develop a driving COM component of fire fighting subsystem which is called by OPC Server to realize the system integration based on OPC component integration.

Authors: Shaoqiang Yuan, Dong Wang, Xingshan Li
Venue: Proceedings of the 2009 International Conference on Computational Intelligence and Natural Computing - Volume 01 (2009)

PenduBot is a new experiment object in the control theory and a typical representation in the underactuated robot, so it is the research focus of control and robot domain. It is known for its strongly nonlinear and naturally unstable properties. To stabilize the PenduBot and verify the control abilities of the algorithm on strongly nonlinear and naturally unstable properties, the thesis presents the purpose that the state-feedback matrixes can be optimized by new bionics algorithm PSO. Based on the introduction of standard PSO algorithm, how to select the position and velocity evolution equations parameters and fitness function became a great emphasis. Next, the simulations were done on the linearized PenduBot model in MATLAB environment by PSO and LQR algorithm separately, and the results were compared. Finally, the comparison results proved the PSO advantages. The expected goal was achieved.
A hybrid meta-heuristic for global optimisation using low-discrepancy sequences of points
Authors: Antoniya Georgieva, Ivan Jordanov
Venue: Computers and Operations Research (2010)

A hybrid novel meta-heuristic technique for bound-constrained global optimisation (GO) is proposed in this paper. We have developed an iterative algorithm called LP@tOptimisation(LP@tO) that uses low-discrepancy sequences of points and meta-heuristic knowledge to find regions of attraction when searching for a global minimum of an objective function. Subsequently, the well-known Nelder-Mead (NM) simplex local search is used to refine the solution found by the LP@tO method. The combination of the two techniques (LP@tO and NM) provides a powerful hybrid optimisation technique, which we call LP@tNM. Its properties-applicability, convergence, consistency and stability are discussed here in detail. The LP@tNM is tested on a number of benchmark multimodal mathematical functions from 2 to 20 dimensions and compared with results from other stochastic heuristic methods.

Agent-Based Distributed Component Services in Spatial Modeling
Authors: Allan J. Brimicombe, Yang Li, Abdullah Al-Zakwani, Chao Li
Venue: Proceedings of the International Conference on Computational Science and Its Applications: Part I (2009)

Agent technologies have been increasingly applied to spatial simulation and modeling in silico. Where multi-agent systems have been used for spatial simulation, agents have tended to be deployed as spatial objects in order to study emergent patterns from micro-level behaviors. Many of these applications only deploy a weak notion of agency. More recently, the concept has emerged in the spatial domain that agents can be deployed as services to assist in complex modeling tasks. Agent-based distributed component services bring a stronger notion of agency to spatial modeling and are particularly suited to achieving interoperability in heterogeneous computational environments. Two case studies are presented. In the first, agent-based services are deployed over a network for spatial data quality analysis. In the second, a variogram agent component is used to demonstrate how a collaborating multi-agent system can provide intelligent, autonomous services to carry out complex operations.
System assistance in structured domain model development
Authors: Susanne Biundo, Werner Stephan
Venue: Proceedings of the Fifteenth international joint conference on Artifical intelligence - Volume 2 (1997)

In this paper, we introduce a domain modeling tool that supports users in the incremental and modular development of verified models of planning domains. It relies on a logic-based concept for systematic domain model construction that provides well-defined, safe operations for the union, extension, and refinement of already existing models. The system is equiped with a deductive component. It automatically performs the proofs necessary to guarantee both the consistency of single models and the safety of operations on models. By means of detailed examples, it is shown how the system has been used for the structured development of a model for a complex, safety-critical planning domain.

Authors: Tiit Hennoste, Olga Gerassimenko, Riina Kasterpalu, Mare Koit, Andriela Rääbis, Krista Strandson
Venue: Proceedings of the 12th International Conference on Text, Speech and Dialogue (2009)

Strategies of giving and receiving phone numbers in Estonian institutional calls are considered with the further aim to develop a telephone-based user interface to data bases which enables interaction in natural Estonian language. The analysis is based on the Estonian dialogue corpus. Human operators give long phone numbers in several parts, making pauses after parts. Pitch contour works as a signal of continuation or finishing the process. Clients give feedback during the process (repetition, particles, and pauses). Special strategies are used by clients to finish receiving the number as well as to initiate repairs in the case of communication problems.

Authors: Liu Jun-rui, Chen Ying-tu, Fan Xiao-ya, Kang Ji-chang
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 01 (2009)

At present, the speed of the communications on PCI is limited by PCI bus, the number of the computer's memory slots and the memory capacity significantly increased, and the management of memory becomes advanced. So, in this paper, the Direct Memory Communication method, abbreviated as DMC, is forwarded. The NIC (the Network Interface Card) based on DMC is inserted into a memory slot, the data is written into the memory while it’s written into the NIC, and the user can accomplished the direct point-to-point communications between the computers through accessing memory. The communications speed isn’t limited by PCI bus, and the copy between memory and NIC is omitted. The author also applied DMC into the high-speed fibre channel switch network, and has been studying the DMC-NIC based on the FB-DIMM DDR2. The experiments’ result shows that this NIC has the following advantages: a higher communications speed, a smaller communications delay and a simpler operation method.

Event-based systems: opportunities and challenges at exascale
Authors: Greg Eisenhauer, Matthew Wolf, Hasan Abbasi, Karsten Schwan
Venue: Proceedings of the Third ACM International Conference on Distributed Event-Based Systems (2009)

Streaming data models have been shown to be useful in many applications requiring high-performance data exchange. Application-level overlay networks are a natural way to realize these applications' data flows and their internal computations, but existing middleware is not designed to scale to the data rates and low overhead computations necessary for the high performance domain. This paper describes EVPath, a middleware infrastructure that supports the construction and management of overlay networks that can be customized both in topology and in the data manipulations being performed. Extending from a previous high-performance publish-subscribe system, EVPath not only provides for the low overhead movement and in-line processing of large data volumes, but also offers the flexibility needed to support the varied data flow and control needs of alternative higher-level streaming models. We explore some of the challenges of high performance event systems, including those experienced when operating an event infrastructure used to transport IO events at the scale of hundred+ thousand nodes. Specifically, when transporting output data from a large-scale simulation running on the ORNL Cray Jaguar petascale machine, a surprising new issue seen in experimentation at scale is the potential for strong perturbation of running applications from inappropriate speeds at which IO is performed. This requires the IO system's event transport to be explicitly scheduled to constrain resource competition, in addition to dynamically setting and changing the topologies of event delivery.

Venue: Proceedings of the 5th International on ConferenceUniversal Access in Human-Computer Interaction. Part II: Intelligent and Ubiquitous Interaction Environments (2009)

This paper describes a projection based information display system, which can make a user see three-dimensional (3D) object with naked eyes. The proposed system is based on Intelligent Space and a projector mounted mobile robot which is called Ubiquitous Display. Human can perceive a 3D structure from 2D retinal images by using diverse cues. As adopted psychological cues, the proposed system makes that a user can perceive 3D object by seeing oblique anamorphosis projected on where the user is facing. Through this, the user can get information more realistically and experience augmented reality which the real and virtual objects coexist without optical devices such as glasses, head-mounted display. Moreover, by using Ubiquitous Display in Intelligent Space, ultimately human centered active information display can be feasible.
Embedded Geometric Active Contour with Shape Constraint for Mass Segmentation
Authors: Ying Wang, Xinbo Gao, Xuelong Li, Dacheng Tao, Bin Wang
Venue: Proceedings of the 13th International Conference on Computer Analysis of Images and Patterns (2009)

Mass boundary segmentation plays an important role in computer aided diagnosis (CAD) system. Since the shape and boundary are crucial discriminant features in CAD, the active contour methods are more competitive in mass segmentation. However, the general active contour methods are not so effective for some cases, because most masses possess very blurry margin that easily induce the contour leaking. To the end, this paper presents an improved geometric active contour for mass segmentation. It firstly introduces the morphological concentric layer model for automatically initializing. Then an embedded level set is used to extract the adaptive shape constraints. For refining the boundary, a new shape constraint function and stopping function are designed for the enhanced geometric active contour method. The proposed method is tested on real mammograms containing masses, and the results suggest that the proposed method could effectively restrain the contour leaking and get better segmented results than general active contour methods.

Herd-Based Target Tracking Protocol in Wireless Sensor Networks
Authors: Xiaofei Xing, Guojun Wang, Jie Wu
Venue: Proceedings of the 4th International Conference on Wireless Algorithms, Systems, and Applications (2009)

Target tracking is a killer application in wireless sensor networks (WSNs). Energy efficiency is one of the most important design goals for target tracking. In this paper, we propose a herd-based target tracking protocol (HTTP) with the notions of node state transition and herd-based node group for target tracking. A sensor node has three states, namely, sleeping state, sensing state, and tracking state. Each sensor node is associated with a weight to be used to make a state transition among the three states. When a target moves into a monitoring area, a cluster node is selected as the herd head that is responsible for reporting the target information to the sink in the network. The sensor node can adjust the frequency of data reporting according to the velocity of the target. Simulation results show that HTTP not only improves the energy efficiency, but also enhances the tracking accuracy.

Authors: Li Xuemei, Ding Lixing, Li Yan, Xu Gang, Li Jibin
Venue: Proceedings of the 2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009) (2009)

A novel approach to HVAC fan machinery fault diagnosis based on combination of artificial neuron network and D-S evidence theory is presented in this paper. Firstly, the system pre-processes the acquisition data from multi sensor, then makes pattern classifies observations based on BP neural network. Secondly, the output values of BPNN are directly taken as the basic probability assignment of the proposition in the frame of discernment. Therefore realizing the objective treatment of the basic probability assignments and avoiding the complexity of constituting the basic probability distribution function. The experiment results demonstrate that the reliability and accuracy to apply the fusion BPNN results with the D-S evidence theory are higher than the independent BPNN diagnosis.

Venue: Proceedings of the 2009 IITA International Conference on Services Science, Management and Engineering (2009)

CFS with the characteristics of high strength and good waterproof performance, gradually is applied to hydraulic structures’ structural strengthening industry. Because there is lack of study on theoretical calculation, according to plane assumption, in accordance with the calculation formula for bearing pier of radial gate given in Design code for hydraulic concrete structures (SL/T 191—96), take side pier for example, a practical calculation formula for the bearing capacity of CFS strengthened pier under the local tension is proposed. Applications shows that the theoretical formula proposed has a certain theoretical and practical value, strengthening effects are reliable, provide reference for future engineering applications.

Program Metamorphosis
Authors: Christoph Reichenbach, Devin Coughlin, Amer Diwan
Venue: Proceedings of the 23rd European Conference on ECOOP 2009 --- Object-Oriented Programming (2009)

Modern development environments support refactoring by providing atomically behaviour-preserving transformations. While useful, these transformations are limited in three ways: (i) atomicity forces transformations to be complex and opaque, (ii) the behaviour preservation requirement disallows deliberate behaviour evolution, and (iii) atomicity limits code reuse opportunities for refactoring implementers.We present `program metamorphosis', a novel approach for program evolution and refactoring that addresses the above limitations by breaking refactorings into smaller steps that need not preserve behaviour individually. Instead, we ensure that sequences of transformations preserve behaviour together, and simultaneously permit selective behavioural change.To evaluate program metamorphosis, we have implemented a prototype plugin for Eclipse. Our analysis and experiments show that (1) our plugin provides correctness guarantees on par with those of Eclipse's own refactorings, (2) both our plugin and our approach address the aforementioned limitations, and (3) our approach fully subsumes traditional refactoring.
