A hybrid sales forecasting system based on clustering and decision trees
Authors: Sébastien Thomassey, Antonio Fiordaliso
Venue: Decision Support Systems (2006)

Competition and globalization imply a very accurate production and sourcing management of the Textile-Apparel-Distribution network actors. A sales forecasting system is required to respond to the versatile textile market and the needs of the distributors. Nowadays, due to the specific constraints of the textile sales (numerous and new items, short life time), existing forecasting models are generally unsuitable or unusable. We propose a forecasting system, based on clustering and classification tools, which performs mid-term forecasting. Performances of our models are evaluated using real data from an important French textile distributor.

Handling distributed authorization with delegation through answer set programming
Authors: Shujing Wang, Yan Zhang
Venue: International Journal of Information Security (2006)

Distributed authorization is an essential issue in computer security. Recent research shows that trust management is a promising approach for the authorization in distributed environments. There are two key issues for a trust management system: how to design an expressive high-level policy language and how to solve the compliance-checking problem (Blaze et&#x00a0;al. in Proceedings of the Symposium on Security and Privacy, pp. 164&#x2013;173, 1996; Proceedings of 2nd International Conference on Financial Cryptography (FC&#x2019;98). LNCS, vol.1465, pp. 254&#x2013;274, 1998), where ordinary logic programming has been used to formalize various distributed authorization policies (Li et&#x00a0;al. in Proceedings of the 2002 IEEE Symposium on Security and Privacy, pp. 114&#x2013;130, 2002; ACM Trans. Inf. Syst. Secur. (TISSEC) 6(1):128&#x2013;171, 2003). In this paper, we employ Answer Set Programming to deal with many complex issues associated with the distributed authorization along the trust management approach. In particular, we propose a formal authorization language $$\mathcal {AL}$$ providing its semantics through Answer Set Programming. Using language $$\mathcal {AL}$$, we cannot only express nonmonotonic delegation policies which have not been considered in previous approaches, but also represent the delegation with depth, separation of duty, and positive and negative authorizations. We also investigate basic computational properties related to our approach. Through two case studies. we further illustrate the application of our approach in distributed environments.
Phase Retrieval Based on a Snake for Image Reconstruction
Authors: Keiko Kondo, Miki Haseyama, Hideo Kitajima
Venue: IEICE - Transactions on Information and Systems (2007)

A new phase retrieval method using an active contour model (snake) for image reconstruction is proposed. The proposed method reconstructs a target image by retrieving the phase from the magnitude of its Fourier transform and the measured area of the image. In general, the measured area is different from the true area where the target image exists. Thus a snake, which can extract the shape of the target image, is utilized to renew the measured area. By processing this renewal iteratively, the area obtained by the snake converges to the true area and as a result the proposed method can accurately reconstruct a target image even when the measured area is different from the true area. Experimental results show the effectiveness of the proposed method.
Deriving managerial benefit from knowledge search: a paradigm shift?
Authors: William R. King, William J. Lekse
Venue: Information and Management (2006)

A conceptual model of knowledge/information (K/I) search and transfer was developed; it was based on three concepts: managers' preferences for internal versus external sources, the importance of relationships between sources and recipients, and the derived managerial benefit. The results of an empirical study demonstrated a high degree of explained variance in managerial benefit and suggested managers' preferences for external sources over internal ones. They also supported the notion that managers use internal, known knowledge search to enhance their reputation and status. These results suggested a shift away from the conventional wisdom of internal preference that is reflected in theories of in-group favoritism and out-group derogation.
An experimental comparison of the new goal programming and the linear programming approaches in the two-group discriminant problems
Authors: Hasan Bal, H. Hasan Örkcü, Salih Çelebioglu
Venue: Computers and Industrial Engineering (2006)

The aim of this article is to consider a new linear programming and two goal programming models for two-group classification problems. When these approaches are applied to the data of real life or of simulation, our proposed new models perform well both in separating the groups and the group-membership predictions of new objects. In discriminant analysis some linear programming models determine the attribute weights and the cut-off value in two steps, but our models determine simultaneously all of these values in one step. Moreover, the results of simulation experiments show that our proposed models outperform significantly than existing linear programming and statistical approaches in attaining higher average hit-ratios.
Mathematical Theory of Duality Quantum Computers
Authors: Stan Gudder
Venue: Quantum Information Processing (2007)

We present a mathematical theory for a new type of quantum computer called a duality quantum computer that has recently been proposed. We discuss the nonunitarity of certain circuits of a duality quantum computer and point out a paradoxical situation that occurs when mixed states are considered. It is shown that a duality quantum computer can measure itself without needing a separate measurement apparatus to determine its final state.
Safety verification of hybrid systems by constraint propagation-based abstraction refinement
Authors: Stefan Ratschan, Zhikun She
Venue: ACM Transactions on Embedded Computing Systems (TECS) (2007)

This paper deals with the problem of safety verification of nonlinear hybrid systems. We start from a classical method that uses interval arithmetic to check whether trajectories can move over the boundaries in a rectangular grid. We put this method into an abstraction refinement framework and improve it by developing an additional refinement step that employs interval-constraint propagation to add information to the abstraction without introducing new grid elements. Moreover, the resulting method allows switching conditions, initial states, and unsafe states to be described by complex constraints, instead of sets that correspond to grid elements. Nevertheless, the method can be easily implemented, since it is based on a well-defined set of constraints, on which one can run any constraint propagation-based solver. Tests of such an implementation are promising.

Groovy in Action
Authors: Dierk Koenig, Andrew Glover, Paul King, Guillaume Laforge, Jon Skeet
Venue:  (2007)

Groovy, the brand-new language for the Java platform, brings to Java many of the features that have made Ruby popular. Groovy in Action is a comprehensive guide to Groovy programming, introducing Java developers to the new dynamic features that Groovy provides. To bring you Groovy in Action, Manning again went to the source by working with a team of expert authors including both members and the Manager of the Groovy Project team. The result is the true definitive guide to the new Groovy language. Groovy in Action introduces Groovy by example, presenting lots of reusable code while explaining the underlying concepts. Java developers new to Groovy find a smooth transition into the dynamic programming world. Groovy experts gain a solid reference that challenges them to explore Groovy deeply and creatively.Because Groovy is so new, most readers will be learning it from scratch. Groovy in Action quickly moves through the Groovy basics, including: Simple and collective Groovy data types Working with Closures and Groovy Control Structures Dynamic Object Orientation, Groovy style Readers are presented with rich and detailed examples illustrating Groovy's enhancements to Java, including How to Work with Builders and the GDK Database programming with Groovy Groovy in Action then demonstrates how to Integrate Groovy with XML, and provides, Tips and Tricks Unit Testing and Build Support Groovy on Windows An additional bonus is a chapter dedicated to Grails, the Groovy Web Application Framework.Early PDF chapters of Groovy in Action are available from the Manning Early Access Program (MEAP) at http://www.manning.com/koenig. As part of this program, readers can also discuss the early manuscript with the author and help shape the manuscript as it's being developed by joining the Author Forum.
WiFi access point pricing as a dynamic game
Authors: John Musacchio, Jean Walrand
Venue: IEEE/ACM Transactions on Networking (TON) (2006)

We study the economic interests of a wireless access point owner and his paying client, and model their interaction as a dynamic game. The key feature of this game is that the players have asymmetric information-the client knows more than the access provider. We find that if a client has a "web browser" utility function (a temporal utility function that grows linearly), it is a Nash equilibrium for the provider to charge the client a constant price per unit time. On the other hand, if the client has a "file transferor" utility function (a utility function that is a step function), the client would be unwilling to pay until the final time slot of the file transfer. We also study an expanded game where an access point sells to a reseller, which in turn sells to a mobile client and show that if the client has a web browser utility function, that constant price is a Nash equilibrium of the three player game. Finally, we study a two player game in which the access point does not know whether he faces a web browser or file transferor type client, and show conditions for which it is not a Nash equilibrium for the access point to maintain a constant price.
Node similarity in the citation graph
Authors: Wangzhong Lu, J. Janssen, E. Milios, N. Japkowicz, Yongzheng Zhang
Venue: Knowledge and Information Systems (2006)

Published scientific articles are linked together into a graph, the citation graph, through their citations. This paper explores the notion of similarity based on connectivity alone, and proposes several algorithms to quantify it. Our metrics take advantage of the local neighborhoods of the nodes in the citation graph. Two variants of link-based similarity estimation between two nodes are described, one based on the separate local neighborhoods of the nodes, and another based on the joint local neighborhood expanded from both nodes at the same time. The algorithms are implemented and evaluated on a subgraph of the citation graph of computer science in a retrieval context. The results are compared with text-based similarity, and demonstrate the complementarity of link-based and text-based retrieval.

Editorial: Single- versus double-blind reviewing
Authors: Richard T. Snodgrass
Venue: ACM Transactions on Database Systems (TODS) (2007)

This editorial analyzes from a variety of perspectives the controversial issue of single-blind versus double-blind reviewing. In single-blind reviewing, the reviewer is unknown to the author, but the identity of the author is known to the reviewer. Double-blind reviewing is more symmetric: The identity of the author and the reviewer are not revealed to each other. We first examine the significant scholarly literature regarding blind reviewing. We then list six benefits claimed for double-blind reviewing and 21 possible costs. To compare these benefits and costs, we propose a double-blind policy for TODS that attempts to minimize the costs while retaining the core benefit of fairness that double-blind reviewing provides, and evaluate that policy against each of the listed benefits and costs. Following that is a general discussion considering several questions: What does this have to do with TODS, does bias exist in computer science, and what is the appropriate decision procedure&quest; We explore the &ldquo;knobs&rdquo; a policy design can manipulate to fine-tune a double-blind review policy. This editorial ends with a specific decision.
Viewpoint Vector Rendering for Efficient Elemental Image Generation
Authors: Kyoung Shin Park, Sung-Wook Min, Yongjoo Cho
Venue: IEICE - Transactions on Information and Systems (2007)

This paper presents a fast elemental image generation algorithm, called the Viewpoint Vector Rendering (VVR), for the computer-generated integral imaging system. VVR produces a set of elemental images in real-time by assembling the segmented area of the directional scenes taken from a range of viewpoints. This algorithm is less affected by system factors such as the number of elemental lens and the number of polygons. It also supports all display modes of the integral imaging system, real, virtual and focused mode. This paper first describes the characteristics of integral imaging system. It then discusses the design, implementation, and performance evaluation of the VVR algorithm, which can be easily adapted to render the integral images of complex 3D objects.
