Authors: Takahito Tashiro, Yoshikazu Nakajima, Yuichi Tamura, Kazuo Yonenobu, Shigeru Uji, Hideki Yoshikawa, Takahiro Ochi, Shinichi Tamura
Venue: Systems and Computers in Japan (2007)

In the treatment of the spine, knowledge of spinal alignment in a standing position, specifically the relative three-dimensional positional relationship between the vertebrae comprising the spine, is very important. In spinal medicine at present, this is generally measured using two-dimensional X-ray images, but it is difficult to measure three-dimensional changes such as the axial rotation of the vertebra. For this reason, measurement techniques have been proposed which use 2D&sol;3D registration methods, three-dimensional statistical models, and the correspondence of interest points in the images. However, these techniques require the use of special equipment and the acquisition of the position of the X-ray imaging device; this is not practical for clinical applications. In this paper, the authors propose a spinal alignment measurement technique which employs only medical equipment which is in general use. In the proposed method, spinal alignment is measured by simultaneously estimating the positions of the vertebrae comprising the spine and the position of the X-ray imaging device. The proposed technique makes possible three-dimensional spinal alignment measurement without changes to current spinal medicine protocols. In this paper, the authors conducted a computer simulation experiment and an experiment using real images, compared the performance of the proposed method with that of conventional methods, and verified the properties of the proposed method. As a result, it was confirmed that the proposed method is effective for measuring the relative positions of vertebrae, as in spinal alignment. &copy; 2007 Wiley Periodicals, Inc.

A non-linear finite-element analysis of buckle propagation in subsea corroded pipelines
Authors: Jianghong Xue
Venue: Finite Elements in Analysis and Design (2006)

A non-linear finite-element analysis for the steady-state buckle propagation phenomenon in subsea corroded pipelines subjected to external hydrostatic pressure is presented. The corroded pipeline is modeled as an infinitely long, cylindrical shell with a non-uniform thickness region. Using Maxwell's theory of two coexisting phases and principle of virtual work, the buckle propagation pressures for the corroded pipeline are calculated from pressure-volume change relations obtained from ABAQUS. The corresponding collapse modes of the corroded pipeline are generated from ABAQUS post-analysis. Symmetric and anti-symmetric collapse modes are found to occur, depending on the depth and angular extent of the corrosion. In addition, snap-through and global collapses are also identified. A parametric study shows how the buckle propagation pressures decrease when either the ratio of corrosion depth to the normal thickness or the angular extent of the corrosion increases. The finite-element model is validated using Timoshenko's classical solutions.
Whatever happened to payola? an empirical analysis of online music sharing
Authors: Sudip Bhattacharjee, Ram Gopal, Kaveepan Lertwachara, James R. Marsden
Venue: Decision Support Systems (2006)

The popularity of online music-sharing networks has attracted interest from the music industry, artists, consumer advocacy groups, the popular press, and government legislative and regulatory entities. P2P networks have become lightning rods for debates on intellectual property rights and music market fates. Yet, to date, little has been based on actual observed activity on online sharing networks. Here we report on an initial P2P network data gathering and analysis endeavor and relate it to market performance of music albums. The relative market performance of music albums is gauged using the list of top 100 albums on the weekly Billboard charts. The P2P sharing data gathered is longitudinal, spanning a period of 8 weeks. We also identify and track data for 47 upcoming album releases providing pre- and post-release comparisons of sharing activity. We offer four main findings: (1) significant piracy opportunity and activity were observed; (2) the level of sharing opportunities are related to albums' relative chart positions; (3) there is evidence of both "pre-purchase sampling" piracy and "lost-sales" piracy; and, (4) sharing activity levels provide leading indicators of direction of movement of albums on the Billboard charts. Points (3) and (4) have particular implications for music marketing and promotion.
Fast estimation of slopes of linear and quasi-linear structures in noisy background, using Fourier methods
Authors: P. Tsitsipis, A. Kontogeorgos, A. Hillaris, X. Moussas, C. Caroubalos, P. Preka-Papadema
Venue: Pattern Recognition (2007)

We present a fast algorithm for slope detection on gray scale images, based on 2D Fourier transform and standard filters; this may be used for line or edge detection. Our approach is based on the calculation of ''energy'' per direction of the image, thus obtaining the ''energy spectrum on slope''(@q). This exhibits local maxima at the points where @q equals the slopes of linear or quasi-linear segments within the image, yet it is not affected by their position within it. The process thus outlined has certain advantages as regards its efficiency of linear structure detection, compared to the Radon and Hough transforms. It was motivated by the study of astrophysical images (solar dynamic radio spectra) which necessitated the introduction of a method for fast extraction of ''drifting structures'', since they appear as linear or quasi-linear segments on these spectra.

Quantile estimation: a minimalist approach
Authors: Yury Bakshi, David A. Hoeflin
Venue: Proceedings of the 38th conference on Winter simulation (2006)

Managing telecommunication networks involves collecting and analyzing large amounts of statistical data. The standard approach to estimating quantiles involves capturing all the relevant data (what may require significant storage/processing capacities), and performing an off-line analysis (what may delay management actions). It is often essential to estimate quantiles as the data are collected, and to take management actions promptly. Towards this goal, we present a minimalist approach to sequentially estimating constant/changing over time quantiles. We follow prior work and devise a fixed-point algorithm, which does not estimate the unknown probability density function at the quantile. Instead, our algorithm uses the log-odds transformation of the observed fractions, and the exponentially smoothed estimates of the standard deviation to update the quantile estimate. For large data streams, this algorithm can significantly reduce the amount of collected data and the complexity of data analysis.
On selection of candidates for opportunistic anypath forwarding
Authors: Zifei Zhong, Junling Wang, Srihari Nelakuditi, Guor-Huar Lu
Venue: ACM SIGMOBILE Mobile Computing and Communications Review (2006)

Opportunistic routing schemes that exploit the broadcast nature of wireless transmissions for selecting the best next-hop at that instant among a set of candidates are being actively explored [1-3]. These schemes which we refer to as opportunistic any-path forwarding (OAPF), reduce the number of transmissions needed for reliable packet delivery.

Analysis of pricing strategies for e-business companies providing information goods and services
Authors: Kang Bae Lee, Sungyeol Yu, Seong Jun Kim
Venue: Computers and Industrial Engineering (2006)

In this paper, we introduce a mathematical model to analyze pricing and service quality strategies for e-business companies providing information services to customers. The basic strategy considered in this paper is that a monopolistic e-business company provides free services to try to earn a profit by developing premium goods or services to market created by their free goods or services. It is a kind of versioning strategy where lower quality versions of information goods are provided free. And a direct network effect was also considered. And we tried to find the profit maximizing strategies for monopolistic e-business companies. As a result, the optimal quality and price for the premium goods or services can be obtained at the same level of the intensity of the direct network effect. And the exact term related with the network externality is derived and insights are demonstrated through numerical explorations.

Name standardization and value specification for machine dependent constants
Authors: Thomas J. Aird, Edward L. Battiste, Nancy E. Bosten, Henry L. Darilek, Walton C. Gregory
Venue: ACM SIGNUM Newsletter (1974)

There are a number of factors which limit the ease of transfer of mathematical software from one computer sytem to another. For FORTRAN implementations of mathematical and statistical algorithms, a primary portability problem is caused by necessary variation in machine dependent constants. The problem occurs for both decimal and machine-specific representations. Redish and Ward (1971) discuss the problem, and propose a solution. This note extends their ideas to additional constants and computer types.
Making sense of virtual environments: action representation, grounding and common sense
Authors: Jean-Luc Lugrin, Marc Cavazza
Venue: Proceedings of the 12th international conference on Intelligent user interfaces (2007)

The development of complex interactive 3D systems raises the need for representations supporting more abstract descriptions of world objects, their behaviour and the world dynamics. The inclusion of Artificial Intelligence representations and their use within 3D graphic worlds face both fundamental and technical issues due to the difference in representational logic between computer graphics and knowledge-based systems. We present a framework for such an integration illustrated by a first prototype.

Authors: Akira Funahashi, Yukiko Matsuoka, Akiya Jouraku, Hiroaki Kitano, Norihiro Kikuchi
Venue: Proceedings of the 38th conference on Winter simulation (2006)

Understanding of logic and dynamics of gene-regulatory and biochemical networks is a major challenge of systems biology. To facilitate this research topic, we have developed CellDesigner, a modeling tool of gene-regulatory and biochemical networks. CellDesigner supports users to easily create such networks using solidly deined and comprehensive graphical representation (SBGN: Systems Biology Graphical Notation). CellDesigner is SBML compliant, and is SBW-enabled software so that it can import/export SBML described documents and can integrate with other SBW-enabled simulation/analysis software packages. CellDesigner also supports simulation and parameter search, which is supported by integration with SBML ODE Solver, enabling us to simulate through our sophisticated graphical user interface. We could also browse and modify existing SBML models with references to existing databases. CellDesigner is implemented in Java, thus it runs on various platforms such as Windows, Linux, and MacOS X. CellDesigner is freely available via the Web.
Applying parallel, dynamic-resolution simulations to accelerate VLSI power estimation
Authors: Dhananjai M. Rao, Philip A. Wilsey
Venue: Proceedings of the 38th conference on Winter simulation (2006)

High resolution models of logic circuits need to be used in simulations to accurately track logic transitions or glitches, which contribute to the most dominant portion of VLSI power dissipated. Unfortunately, simulating large, high resolution models is a time consuming task. Although more abstract models that simulate faster can be used, they are less accurate as details of glitching activity are absent. This study proposes an alternatively approach that dynamically (i.e., during simulation) changes the resolution of a model to strike a better balance between accuracy and performance. Simulation-time resolution changes are performed using a novel methodology called Dynamic Component Substitution (DCS). This paper presents the issues involved in applying DCS to accelerate parallel power simulations of digital logic circuits. The experiments indicate that the proposed strategy can increase performance by 3x with negligible deviations in power estimates but consuming about 2x more memory.
A note on the tool switching problem of a flexible machine
Authors: Kari Salonen, Csaba Raduly-Baka, Olli S. Nevalainen
Venue: Computers and Industrial Engineering (2006)

The problem of minimizing the total number of tool switches for a numerically controlled flexible machine is considered. A set of parts is to be processed with the machine. Each part needs a set of tools which should reside in the magazine of the machine at the moment of processing. Because of the limited capacity of the magazine, tools must be switched and the objective is to minimize the amount of this work. We propose an algorithm which tries to avoid sticking to a local minimum by repeated searches from different initial starting points which are created by repeated construction of super parts from parts with similar tools. The proposed algorithm and a number of efficient heuristics presented in the literature are empirically tested by both random test problems and real production data. The new algorithm performs well when considering the tradeoff between solution quality and running time.
