The linkage of production processes in manufacturing systems is a major issue affecting system’s performance. Such linkage is defined by the way material and information flows are established. A control policy in manufacturing systems imposes a particular pattern of information flow on the factory. Similarly, a specific implementation of transportation policies defines a pattern of material flow between two uncoupled processes.This paper studies the condition of material flow in KSC. Furthermore, through simulation, proper flow of material with the aim of achieving Company's development plan as well as increasing the production capacity from 2.1 to 4.2 million tons per year has been provided.For this, the exchanges among different units and various modes for transporting material among these units have been studied. Considering the hourly distribution of materials and the share of railway and road network in the material flow, four scenarios have been proposed. In each scenario various solutions for improving the condition of material flow have been studied.
Refactoring Effect Estimation Based on Complexity Metrics
Authors: Yoshiki Higo, Yoshihiro Matsumoto, Shinji Kusumoto, Katsuro Inoue
Venue: Proceedings of the 19th Australian Conference on Software Engineering (2008)

Refactoring is a set of operations to improve maintainability or understandability or other attributes of a software system without changing the external behavior of it, and it is getting much attention recently. However it is difficult to perform appropriate refactorings since the impact of refactoring should justify the cost. Therefore, before a refactoring is really performed, the effect and the cost of it should be estimated. The estimation makes it possible for us to adequately assess whether each refactoring should be performed or not. This paper shows that it is difficult for developers to perform appropriate refactorings, and proposes a method estimating refactoring effect. The method has been implemented as a software tool, and a case study was conducted with it. The result of the case study showed that the estimation of the tool helped a developer of the target software system to perform an appropriate refactoring.

Authors: Jin Suk Kang, Yonghee You, Mee Young Sung, Taikyeong T. Jeong, Jongan Park
Venue: Proceedings of the Seventh IEEE/ACIS International Conference on Computer and Information Science (icis 2008) (2008)

Mobile and wireless technologies have evolved rapidly in recent years, especially the development of hardware devices, such as PDA and Smartphone. Telecommunication service providers, manufacturers and other developers have launch-ed different kinds of services and applications in these mobile devices. Mobile Geographic Information and Location Based Service appear recently to help people to establish spatial relationship with the surroundings. Map, which is a useful tool to assist a person to define a position in a particular area, is usually included in these systems. However, there is no standard format of graphic presentation for map in mobile devices. In this paper, the effective method was suggested for the transmission of the geographic information acquired by camera attached to a PDA such as position data, attitude data, and image data in the wireless internet environment in real-time.
Maintaining consistency in a failure-prone P2P database network during transaction processing
Authors: Md Mehedi Masud, Iluju Kiringa
Venue: Proceedings of the 2008 international workshop on Data management in peer-to-peer systems (2008)

A peer database network consists of peers in which each peer has its own pre-existing local database system (LDBS). In a peer database network, the integration of sources is performed using pairwise mappings, and a peer shares its local database information with other peers by establishing data sharing constraints either by schema-level or data-level mappings. In our peer database network, we assume that each peer uses data-level mappings [7] for sharing data and resolving data heterogeneity. In this paper, we first introduce the execution semantics of a transaction in such a peer database network and formalize the problems of ensuring transaction execution consistency in the presence of failures of transactions. Since there is no global transaction manager and each peer executes transactions independently in a peer database network, different peers may have different execution views for the same set of transactions. Addressing this issue, we present an approach for ensuring a consistent execution of transactions in a peer database network.
Apprenticeship learning using linear programming
Authors: Umar Syed, Michael Bowling, Robert E. Schapire
Venue: Proceedings of the 25th international conference on Machine learning (2008)

In apprenticeship learning, the goal is to learn a policy in a Markov decision process that is at least as good as a policy demonstrated by an expert. The difficulty arises in that the MDP's true reward function is assumed to be unknown. We show how to frame apprenticeship learning as a linear programming problem, and show that using an off-the-shelf LP solver to solve this problem results in a substantial improvement in running time over existing methods---up to two orders of magnitude faster in our experiments. Additionally, our approach produces stationary policies, while all existing methods for apprenticeship learning output policies that are "mixed", i.e. randomized combinations of stationary policies. The technique used is general enough to convert any mixed policy to a stationary policy.
Cardiac Arrhythmia Detection based on Signal Variation Characteristic
Authors: Chusak Thanawattano, Surapol Tan-a-ram
Venue: Proceedings of the 2008 International Conference on BioMedical Engineering and Informatics - Volume 02 (2008)

This paper presents the classification of cardiac arrhythmia based on the signal variation characteristic of each beat type. Considered beat types including the normal beat, fusion beat and premature ventricular contraction beats are differentiated to obtain feature sets. Using the principal component analysis estimation, the detection selects the class by searching the minimal norm of the error vector obtained by basis of each type. Without the help of the timing interval information, the proposed classifier outperforms the algorithm presented in the literature. The classification accuracy of the proposed algorithm achieves perfect detection.
Minimizing collateral damage by proactive surge protection
Authors: Jerry Chou, Bill Lin, Subhabrata Sen, Oliver Spatscheck
Venue: Proceedings of the 2007 workshop on Large scale attack defense (2007)

Existing mechanisms for defending against distributed denial-of-service (DDoS) attacks are generally reactive in nature. However, the onset of large-scale bandwidth-based attacks can occur suddenly, potentially knocking out substantial parts of a network before reactive defenses can respond. Even for traffic flows that are not under direct attack, significant collateral damage will result if these flows pass through links that are common to attack routes. This paper presents a proactive-surge-protection (PSP) mechanism that aims to provide a broad first line of defense against DDoS attacks. Our solution aims to minimize collateral damage by providing bandwidth isolation between traffic flows. This isolation is achieved through a combination of traffic forecasting, proportional allocation of network capacity, metering and tagging of packets at the network perimeter, and preferential dropping of packets inside the network. Our solution is readily deployable using existing router mechanisms. Simulations across three large backbone networks show that up to 95.5% of the network could suffer collateral damage without protection, but our solution was able to reduce the amount of collateral damage by 60.5-97.8%, even with a coarse-grained forecasting scheme.
Blurring the line between real and digital: pinning objects to wall-sized displays
Authors: Daniel Stødle, Otto J. Anshus
Venue: Proceedings of the 2008 workshop on Immersive projection technologies/Emerging display technologiges (2008)

Billboards are everywhere, enabling users to interact by leaving documents, images, ads or clippings for others to see. There is currently no simple and transparent way to replicate this interaction pattern in a wall-sized display context. Users must first employ devices like scanners or digital cameras to digitize the content they wish to share. Then the digitized content must be manually transferred to some computer, before the user can display and arrange it on the desktop. This paper presents a system that supports the classic billboard interaction pattern in a display wall context. The user briefly holds the content to digitize anywhere in front of the display wall, and an image of it appears at the same location. The system comprises a 6x3 m high-resolution wall-sized display, a gesturebased human-computer interface and a ceiling-mounted steerable camera, which together enable transparent and low latency object imaging.
Introduction: Special issue on constraint satisfaction techniques for planning and scheduling problems
Authors: Miguel A. Salido, Antonio Garrido, Roman Barták
Venue: Engineering Applications of Artificial Intelligence (2008)

The areas of Artificial Intelligence (AI) planning and scheduling have seen important advances thanks to the application of constraint satisfaction models and techniques. Most real-world problems are typically known as highly coupled planning and scheduling problems, where resources must be allocated so as to optimize overall performance objectives. Therefore, solving these problems requires an adequate mixture of planning, scheduling and resource allocation to competing goal activities over time in the presence of complex state-dependent constraints; i.e., solutions to these problems must integrate resource allocation and plan synthesis capabilities, which can be efficiently managed by using constraint techniques. This special issue of Engineering Applications of Artificial Intelligence on ''Constraint Satisfaction Techniques for Planning and Scheduling Problems'' compiles a selection of papers of COPLAS'07: the joint CP/ICAPS-2007 workshop of the same name and presents novel issues on planning, scheduling, constraint programming/constraint satisfaction problems (CSPs) and many other common areas that exist among them. On the whole, this issue mainly focus on managing complex problems where planning, scheduling and constraint satisfaction must be combined and/or interrelated, which entails an enormous potential for practical applications and future research.
Optimal control of shallow water flow using time-delay function
Authors: Kenichiro Shimamura, Mutsuto Kawahara
Venue: International Journal of Computational Fluid Dynamics (2007)

This paper presents an optimal control system that includes a time-delay function for application to flood control setups with a retardation area. This system consists of the present and past controls that express flow behaviour in the retardation area. Optimal control theory is used to obtain a control discharge that satisfies the state equation including the time-delay function and minimizes the performance function. The optimal control and the delayed control discharges are obtained by the solution of an adjoint equation. The weighted gradient method is employed as a minimization algorithm. The Galerkin finite element procedure is employed to discretize the state and adjoint equations in the spatial direction. The bubble function interpolation, originated by the authors' group, using a stabilized term, is employed for the discretization in space. The flood flow in the Tsurumi river is presented as a numerical model. We show in this paper that floods can be controlled by means of a time-delay function.

A TOA-AOA-based NLOS error mitigation method for location estimation
Authors: Hong Tang, Yongwan Park, Tianshuang Qiu
Venue: EURASIP Journal on Advances in Signal Processing (2008)

This paper proposes a geometric method to locate a mobile station (MS) in a mobile cellular network when both the range and angle measurements are corrupted by non-line-of-sight (NLOS) errors. The MS location is restricted to an enclosed region by geometric constraints from the temporal-spatial characteristics of the radio propagation channel. A closed-form equation of the MS position, time of arrival (TOA), angle of arrival (AOA), and angle spread is provided. The solution space of the equation is very large because the angle spreads are random variables in nature. A constrained objective function is constructed to further limit the MS position. A Lagrange multiplier-based solution and a numerical solution are proposed to resolve the MS position. The estimation quality of the estimator in term of "biased" or "unbiased" is discussed. The scale factors, which may be used to evaluate NLOS propagation level, can be estimated by the proposed method. AOA seen at base stations may be corrected to some degree. The performance comparisons among the proposed method and other hybrid location methods are investigated on different NLOS error models and with two scenarios of cell layout. It is found that the proposed method can deal with NLOS error effectively, and it is attractive for location estimation in cellular networks.
An integrated access control for securely querying and updating XML data
Authors: Maggie Duong, Yanchun Zhang
Venue: Proceedings of the nineteenth conference on Australasian database - Volume 75 (2008)

Many existing access controls use node filtering or querying rewriting techniques. These techniques require rather time-consuming processes such as parsing, labeling, pruning and/or rewriting queries into safe ones each time a user requests a query or takes an action. In this paper, we propose a fine-grained access control model, named SecureX, which supports read and write privileges. With our novel access control concept, various access types are introduced, including those for determining if a user has the right to change XML structure. Furthermore, SecureX can be integrated well with a dynamic labeling scheme to eliminate repetitive labeling and pruning processes when determining a user view. This brings about advantages of speeding up searching and querying processes. When comparing to a traditional node filtering technique, our integrated access control model takes less processing steps. Experiments have shown effectiveness of our approach.
Design of Microarray Probes for Detection of Mutations
Authors: Pedro Almeida, Laura Carreto, José Luís Oliveira
Venue: Proceedings of the 2008 International Conference on Biocomputation, Bioinformatics, and Biomedical Technologies (2008)

As we gather knowledge about the relationship between genetic mutations and the predisposition to certain diseases, it becomes of importance to screen for single nucleotide polymorphisms (SNP) in entire populations, using low cost and fast methods. Microarrays are a recent technology characterized by the miniaturization of DNA hybridization sampling and the scalability of the monitored DNA sequences, making available the detection of genomic polymorphisms in a large scale. A draw back in this technology, however, is the large time consuming work associated with the design of probes for such propose, due to the several properties that all probes must have in common and, at same time, the uniqueness of each one.In this article we present a computational solution to automate the process of probe design for the purpose of mutations detection, reducing the overall workflow time and increasing the accuracy of the final probes.
Fuzzy interpolative reasoning for sparse fuzzy rule-based systems based on the ranking values of fuzzy sets
Authors: Li-Wei Lee, Shyi-Ming Chen
Venue: Expert Systems with Applications: An International Journal (2008)

Fuzzy interpolative reasoning is an important research topic of sparse fuzzy rule-based systems. In recent years, some methods have been presented for dealing with fuzzy interpolative reasoning. However, the involving fuzzy sets appearing in the antecedents of fuzzy rules of the existing fuzzy interpolative reasoning methods must be normal and non-overlapping. Moreover, the reasoning conclusions of the existing fuzzy interpolative reasoning methods sometimes become abnormal fuzzy sets. In this paper, in order to overcome the drawbacks of the existing fuzzy interpolative reasoning methods, we present a new fuzzy interpolative reasoning method for sparse fuzzy rule-based systems based on the ranking values of fuzzy sets. The proposed fuzzy interpolative reasoning method can handle the situation of non-normal and overlapping fuzzy sets appearing in the antecedents of fuzzy rules. It can overcome the drawbacks of the existing fuzzy interpolative reasoning methods in sparse fuzzy rule-based systems.
Design and Performance Evaluation of Space---time Receivers with Dynamically Adjustable Tap Delays
Authors: Tai-Kuo Woo
Venue: Wireless Personal Communications: An International Journal (2008)

The delay elements of a conventional two-dimensional space---time receiver are fixed. The rather inflexible design is inappropriate since the received signals among the antenna branches are correlated due to limited spacing, and the fading environment is time-varying. In this paper we propose a dynamic finger assignment strategy for a space---time receiver, where the delay taps are adjusted dynamically, based on the theory of finite projective planes, to improve the signal-to-noise ratio in correlated antenna branches. The proposed finite projective plane (FPP) based finger assignment scheme maximizes the collected energy by dynamically setting the tap delays depending on the correlation among antenna branches and the delay spread of the channel. In the performance evaluation, we demonstrate that the FPP based finger assignment scheme can improve the signal-to-noise ratio significantly in comparison to the conventional mesh-grid configuration when the correlation among antenna branches is high and the channel dispersion is relatively long in comparison to the overall span of the fingers. However, the gain is moderate if the channel dispersion ratio is short, where the gain of reduced correlation among antenna branches must compensate for the reduced signal-to-noise ratio due to the missed signals.

Understanding and Countering Insider Threats in Software Development
Authors: Michael Franz
Venue: Proceedings of the 2008 International MCETECH Conference on e-Technologies (2008)

E-commerce and e-government depend on trustworthy software platforms. Unfortunately, barely a week goes by without the discovery of a "critical" software vulnerability that would give a remote party complete access to a large number of network-attached computers. Considering the rising financial incentives and the immeasurable strategic importance of such vulnerabilities, one should assume that there are parties within commercial software companies that are actively scouting out (and perhaps even inserting) such errors for future exploitation.For various reasons that we touch on briefly, software manufacturers appear to be unwilling to even discuss this possibility. We explain why open-source software development is not a solution, either. We then outline an approach that significantly reduces the problem, even when malicious insiders are part of the software development team. Our approach is based on running several slightly different versions of the same software in parallel on different cores of a multiprocessor. As a beneficial side effect, our method is able to locate actual programming errors.
