Agent communication and artificial institutions
Authors: Nicoletta Fornara, Francesco Viganò, Marco Colombetti
Venue: Autonomous Agents and Multi-Agent Systems (2007)

In this paper we propose an application-independent model for the definition of artificial institutions that can be used to define open multi-agent systems. Such a model of institutional reality makes us able also to define an objective and external semantics of a commitment-based Agent Communication Language (ACL). In particular we propose to regard an ACL as a set of conventions to act on a fragment of institutional reality, defined in the context of an artificial institution. Another contribution of the work presented in this paper is an operational definition of norms, a crucial component of artificial institutions. In fact in open systems interacting agents might not conform to the specifications. We regard norms as event-driven rules that when are fired by events happening in the system create or cancel a set of commitments. An interesting aspect of our proposal is that both the definition of the ACL and the definition of norms are based on the same notion of commitment. Therefore an agent capable of reasoning on commitments can reason on the semantics of communicative acts and on the system of norms.
A novel fuzzy classification entropy approach to image thresholding
Authors: Dong Liu, Zhaohui Jiang, Huanqing Feng
Venue: Pattern Recognition Letters (2006)

In this paper, a novel fuzzy classification entropy approach to generic image thresholding is proposed. Under the assumption that the grayscale histogram of an image follows multimodal distribution, the fuzzy membership function is modified, and the fuzzy entropy is redefined, named fuzzy classification entropy (FCE), to indicate the fitness of the membership function to the actual histogram. The novel membership function and FCE consider not only inter-class distinctness, but also intra-class variety, which provides more accurate description of the histogram. We present bi-level and multi-level thresholding using FCE and conduct experiments on many grayscale images. The results show that the novel method can get moderate thresholds for most images, with better visual quality and less complexity than other fuzzy entropy based methods.
Design and Analysis of an Adaptive, Global Strategy for Detecting and Mitigating Distributed DoS Attacks in GRID Environments
Authors: Taieb Znati, James Amadei, Daniel R. Pazehoski, Scott Sweeny
Venue: Proceedings of the 39th annual Symposium on Simulation (2006)

Basic protection schemes against Denial-of-Service (DoS) are based on a perimeter-based model, where attacks are dealt with after they occur. This is quite often too late to prevent damage or loss of resources and service. The focus of this paper is to investigate a distributed defense method that can neutralize the attack before it reaches the potential target in mass. In order to effectively implement this method, this paper proposes a progressive, globally deployable sentinel scheme for data sampling, packet inspection, and DoS attack detection and recovery. A simulation framework is developed to study the performance of the proposed scheme. The results show a significant improvement in how the network deals with DoS attacks, in comparison to local DoS detection and prevention schemes.

Motion templates for automatic classification and retrieval of motion capture data
Authors: Meinard Müller, Tido Röder
Venue: Proceedings of the 2006 ACM SIGGRAPH/Eurographics symposium on Computer animation (2006)

This paper presents new methods for automatic classification and retrieval of motion capture data facilitating the identification of logically related motions scattered in some database. As the main ingredient, we introduce the concept of motion templates (MTs), by which the essence of an entire class of logically related motions can be captured in an explicit and semantically interpretable matrix representation. The key property of MTs is that the variable aspects of a motion class can be automatically masked out in the comparison with unknown motion data. This facilitates robust and efficient motion retrieval even in the presence of large spatio-temporal variations. Furthermore, we describe how to learn an MT for a specific motion class from a given set of training motions. In our extensive experiments, which are based on several hours of motion data, MTs proved to be a powerful concept for motion annotation and retrieval, yielding accurate results even for highly variable motion classes such as cartwheels, lying down, or throwing motions.
Every Linear Pseudo BL-Algebra Admits a State
Authors: Anatolij Dvure&#x010d;enskij
Venue: Soft Computing - A Fusion of Foundations, Methodologies and Applications (2007)

We show that every linear pseudo BL-algebra, hence every representable one, admits a state and is good. This solves positively the problem on the existence of states raised in Dvure&#x010d;enskij and Rach&#x016f;nek (Probabilistic averaging in bounded communitative residuated &#x2113;-monoids, 2006), and gives a partial answer to the problem on good pseudo BL-algebras from [Di Nola, Georgescu and Iorgulescu (Multiple Val Logic 8:715&#x2013;750, 2002) Problem 3.21]. Moreover, we present that every saturated linear pseudo BL-algebra can be expressed as an ordinal sum of H&#x00e1;jek&#x2019;s type of irreducible pseudo linear pseudo BL-algebras.
Hierarchical parameter setting for hybrid grid generation based on the STEP model representation
Authors: Aristotelis N. Athanasiadis, Herman Deconinck
Venue: Applied Numerical Mathematics (2004)

In this work we present a method for defining parameters for hybrid grid generation in complex geometries. The method is hierarchical and uses the topological information present in the domain model. The latter is based on the STEP ISO boundary representation allowing compatibility with all major CAD systems. The parameter definition permits a detailed control of the grid spacing in the semi-structured part of the grid, while ensuring a smooth spacing variation across the model. Furthermore, arbitrary grid sources can be defined to control the grid size in the unstructured part of the grid if the default size variation is not satisfactory. Finally, an algorithm has been developed to automatically derive many of the grid generation parameters, creating high quality surface grids for complex models with minimum user input.

A microprogramming design laboratory
Authors: Christopher Vickery
Venue: ACM SIGMICRO Newsletter (1976)

Sophisticated design aids are available to help automate microprogram development both for large, complex computers and for microprocessor-based systems. These aids include procedures for source code verification, object code generation, micro-program simulation, and interactive debugging. For various reasons, such aids are generally not well-developed for micro-programmable minicomputers. This paper describes a microprogramming laboratory developed for the Interdata 85 minicomputer which uses both the minicomputer itself as well as the time-sharing and batch facilities of a large computer center. Experience with the laboratory has shown that the facility for interacting with a microprogram is as important as the availability of complete diagnostic information. The argument is made that design automation aids for microprogramming minicomputers could be produced most efficiently from standardized assembly and simulation programs.

A genetic algorithm for the optimisation of assembly sequences
Authors: Romeo M. Marian, Lee H. S. Luong, Kazem Abhary
Venue: Computers and Industrial Engineering (2006)

This paper describes a Genetic Algorithm (GA) designed to optimise the Assembly Sequence Planning Problem (ASPP), an extremely diverse, large scale and highly constrained combinatorial problem. The modelling of the ASPP problem, Which has to be able to encode any industrial-size product with realistic constraints, and the GA have been designed to accommodate any type of assembly plan and component. A number of specific modelling issues necessary for understanding the manner in which the algorithm works and how it relates to real-life problems, are succinctly presented, as they have to be taken into account/adapted/solved prior to Solving and Optimising (S/O) the problem. The GA has a classical structure but modified genetic operators, to avoid the combinatorial explosion. It works only with feasible assembly sequences and has the ability to search the entire solution space of full-scale, unabridged problems of industrial size. A case study illustrates the application of the proposed GA for a 25-components product.
Loose Coupling and Healthcare Organizations: Deployment Strategies for Groupware
Authors: David Pinelle, Carl Gutwin
Venue: Computer Supported Cooperative Work (2006)

Healthcare organizations are often organized in a modular, loosely coupled fashion where separate and semi-autonomous work units specialize in different areas of care delivery. This partitioning allows each unit to adapt to emerging practice standards in its area of expertise and to adjust to its local work environment. However, organizational loose coupling can limit the flow of information within organizations and can make it difficult to coordinate services when patients' care is dependent on professionals from more than one unit. Groupware systems have the potential to improve coordination and information access in healthcare organizations. However, modularity and loose coupling make it difficult to introduce new systems when they span more than one unit, since authority is not always centralized and since perceptions and frames of reference on new deployments differ across units. In this paper, we define a groupware deployment framework for loosely coupled healthcare organizations that has two parts: a set of deployment challenges and a set of deployment strategies. The deployment challenges include: difficulties centralizing deployments, perceptions of inequity, role conflicts, and problems achieving critical mass. The deployment strategies outline a preliminary set of approaches for addressing the difficulties of deploying CSCW systems in loosely coupled healthcare organizations. We illustrate the framework by presenting a case study of a groupware deployment in a home care setting.
Unique factorization in ACL2: Euclidean domains
Authors: John R. Cowles, Ruben Gamboa
Venue: Proceedings of the sixth international workshop on the ACL2 theorem prover and its applications (2006)

ACL2 is used to systematically study domains whose elements can be "uniquely" factored into products of "irreducible" elements. The best known examples of such domains are the positive integers, which can be factored into products of primes, and univariate polynomials with rational coefficients, which can be factored into products of irreducible polynomials. There are many other such domains.Euclidean domains are an algebraic abstraction, of both the positive integers and the rational polynomials, in which the usual proofs of unique factorization, for both the integers and the polynomials, can be generalized.

A hybrid optimization/simulation approach for a distribution network design of 3PLS
Authors: Hyun Jeung Ko, Chang Seong Ko, Taioun Kim
Venue: Computers and Industrial Engineering (2006)

Third party logistics service providers (3PLs) are playing an increasing role in the management of supply chains. Especially in warehousing and transportation services, a number of clients expect for 3PLs to improve lead times, fill rates, inventory levels, etc. Hence, these 3PLs are under pressure to meet various clients' service requirements in a dynamic and uncertain business environment. As a result, 3PLs should maintain an efficient distribution system of high performance competitive advantages. In this paper, we propose a hybrid optimization/simulation approach to design a distribution network for 3PLs in consideration of the performance of the warehouses. The optimization model uses a genetic algorithm to determine dynamic distribution network structures. Subsequently, the simulation model is applied to capture the uncertainty in clients' demands, order-picking time, and travel time for the capacity plans of the warehouses based on service time. The approach is applied to an example problem for examining its validity.

Demand assigned capacity management (DACM) in IP over optical (IPO) networks
Authors: Daniel O. Awduche, Bijan Jabbari
Venue: IEEE/ACM Transactions on Networking (TON) (2006)

The demand assigned capacity management (DACM) problem in IP over optical (IPO) network aims at devising efficient bandwidth replenishment schedules from the optical domain conditioned upon traffic evolution processes in the IP domain. A replenishment schedule specifies the location, sizing, and sequencing of link capacity expansions to support the growth of Internet traffic demand in the IP network subject to economic considerations. A major distinction in the approach presented in this paper is the focus of attention on the economics of "excess bandwidth" in the IP domain, which can be viewed as an inventory system that is endowed with fixed and variable costs and depletes with increase in IP traffic demand requiring replenishment from the optical domain. We develop mathematical models to address the DACM problem in IPO networks based on a class of inventory management replenishment methods. We apply the technique to IPO networks that implement capacity adaptive routing in the IP domain and networks without capacity adaptive routing. We analyze the performance characteristics under both scenarios, in terms of minimizing cumulative replenishment cost over an interval of time. For the non-capacity adaptive routing scenario, we consider a shortest path approach in the IP domain, specifically OSPF. For the capacity adaptive scenario, we use an online constraint-based routing scheme. This study represents an application of integrated traffic engineering which concerns collaborative decision making targeted towards network performance improvement that takes into consideration traffic demands, control capabilities, and network assets at different levels in the network hierarchy.
