The operational risk tree methodology for managing operational risk exposure and measuring capital requirements
Authors: Henry Lee
Venue: Proceedings of the 38th conference on Winter simulation (2006)

Monte Carlo simulation is applied to measuring operational risk via a modified decision tree. The author describes a simulation based approach to measuring economic and regulatory capital for operational risk. Except in relatively rare cases where sufficient data exists, quantitative operational risk has grown to depend upon expert opinion via scenario analysis to fill in the missing data. The author explains the limitations and shortcomings of the current approach and details an alternative approach using a modified decision tree to address many of these shortcomings. While in the absence of data we still depend upon expert opinion, there is good reason to believe that the method of collecting this opinion can have great impact upon the confidence in, and reproducibility of, the results.

Diffusion dynamics in small-world networks with heterogeneous consumers
Authors: Sebastiano A. Delre, Wander Jager, Marco A. Janssen
Venue: Computational Mathematical Organization Theory (2007)

Diffusions of new products and technologies through social networks can be formalized as spreading of infectious diseases. However, while epidemiological models describe infection in terms of transmissibility, we propose a diffusion model that explicitly includes consumer decision-making affected by social influences and word-of-mouth processes. In our agent-based model consumers' probability of adoption depends on the external marketing effort and on the internal influence that each consumer perceives in his/her personal networks. Maintaining a given marketing effort and assuming its effect on the probability of adoption as linear, we can study how social processes affect diffusion dynamics and how the speed of the diffusion depends on the network structure and on consumer heterogeneity. First, we show that the speed of diffusion changes with the degree of randomness in the network. In markets with high social influence and in which consumers have a sufficiently large local network, the speed is low in regular networks, it increases in small-world networks and, contrarily to what epidemic models suggest, it becomes very low again in random networks. Second, we show that heterogeneity helps the diffusion. Ceteris paribus and varying the degree of heterogeneity in the population of agents simulation results show that the more heterogeneous the population, the faster the speed of the diffusion. These results can contribute to the development of marketing strategies for the launch and the dissemination of new products and technologies, especially in turbulent and fashionable markets.

Categorizing commercial products for customer oriented online retailing
Authors: Sue Young Choi, Byounggu Choi, Heeseok Lee
Venue: Computers and Industrial Engineering (2006)

Online retailing can offer several benefits. In order to realize these benefits, a commercial web site needs to ameliorate its deficiencies due to the absence of actual physical products. Although the use and popularity of the Internet continues to increase, it is still unclear how online retailers can establish effective online retailing strategies to capitalize on their benefits. For this clarification, this paper proposes a framework to categorize products according to consumers' involvement and information quality fitness. Involvement refers to the degree of psychological identification or emotional ties consumers have with a particular product. Information quality fitness refers to the extent to which a product can fit with shopper's requirements for online information. Thirty-six commercial products are empirically tested. It is found that products can be grouped into four categories such as 'complex,' 'intelligent,' 'light,' and 'simple.' This categorization can help understand product characteristics when they are sold via the Internet. Our finding implies that online retailers need to formulate their retailing strategies in view of these product categories.
Contributions of prefrontal cue-, delay-, and response-period activity to the decision process of saccade direction in a free-choice ODR task
Authors: Kei Watanabe, Saori Igaki, Shintaro Funahashi
Venue: Neural Networks (2006)

To examine how the dorsolateral prefrontal cortex (DLPFC) contributes to the decision process of the saccade direction, we recorded single-neuron activity while two monkeys performed two oculomotor delayed-response (ODR) tasks. In an ordinary ODR task, monkeys were required to make a memory-guided saccade to the cue location after a 3-s delay. In a self-selection version of the ODR task (S-ODR), four identical visual cues were presented simultaneously at the cue period, and monkeys were required to make a saccade toward any one of four directions after a 3-s delay. By comparing the same neuron's activity between two tasks, we found (1) neurons having directional cue-period activity in the ODR task did not show directionally selective activity in the S-ODR task, (2) neurons having directional pre-saccadic activity showed highly similar directional preferences in two tasks and exhibited temporal coupling between the onset of pre-saccadic activity and the initiation of saccadic eye movements, (3) neurons with directional delay-period activity in the ODR task exhibited similar directional preferences and showed gradual increase in the strength of the directional selectivity toward the end of the delay period in the S-ODR task. These results suggest that directional delay-period activity contributes to the decision process of the saccade direction in the S-ODR task, while directional cue-period and pre-saccadic activities do not. The gradual increase of the directional selectivity in delay-period activity might correspond to neural correlates of the decision process of the saccade direction in the S-ODR task.

Low-Cost IP Core Test Using Tri-Template-Based Codes
Authors: Gang Zeng, Hideo Ito
Venue: IEICE - Transactions on Information and Systems (2007)

A tri-template-based codes (TTBC) method is proposed to reduce test cost of intellectual property (IP) cores. In order to reduce test data volume (TDV), the approach utilizes three templates, i.e., all 0, all 1, and the previously applied test data, for generating the subsequent test data by flipping the inconsistent bits. The approach employs a small number of test channels I to supply a large number of internal scan chains 2I-3 such that it can achieve significant reduction in test application time (TAT). Furthermore, as a non-intrusive and automatic test pattern generation (ATPG) independent solution, the approach is suitable for IP core testing because it requires neither redesign of the core under test (CUT) nor running any additional ATPG for the encoding procedure. In addition, the decoder has low hardware overhead, and its design is independent of the CUT and the given test set. Theoretical analysis and experimental results for ISCAS 89 benchmark circuits have proven the efficiency of the proposed approach.
SOM Segmentation of gray scale images for optical recognition
Authors: Jesús Lázaro, Jagoba Arias, José L. Martín, Aitzol Zuloaga, Carlos Cuadrado
Venue: Pattern Recognition Letters (2006)

This paper describes a clustering technique using Self Organizing Maps and a two-dimensional histogram of the image. The two-dimensional histogram is found using the pixel value and the mean in the neighborhood. This histogram is fed to a self organizing map that divides the histogram into regions. Carefully selecting the number of regions, a scheme that allows an optimum optical recognition of texts can be found. The algorithm is specially suited for optical recognition application where a very high degree of confidence is needed. As an example application, the algorithm has been tested in a voting application, where a high degree of precision is required. Furthermore, the algorithm can be extended to any other thresholding or clustering applications.
On the information and representation of non-Euclidean pairwise data
Authors: Julian Laub, Volker Roth, Joachim M. Buhmann, Klaus-Robert Müller
Venue: Pattern Recognition (2006)

Two common data representations are mostly used in intelligent data analysis, namely the vectorial and the pairwise representation. Pairwise data which satisfy the restrictive conditions of Euclidean spaces can be faithfully translated into a Euclidean vectorial representation by embedding. Non-metric pairwise data with violations of symmetry, reflexivity or triangle inequality pose a substantial conceptual problem for pattern recognition since the amount of predictive structural information beyond what can be measured by embeddings is unclear. We show by systematic modeling of non-Euclidean pairwise data that there exists metric violations which can carry valuable problem specific information. Furthermore, Euclidean and non-metric data can be unified on the level of structural information contained in the data. Stable component analysis selects linear subspaces which are particularly insensitive to data fluctuations. Experimental results from different domains support our pattern recognition strategy.

Simulation-based scheduling of parallel wire-bonders with limited clamp&paddles
Authors: Daniel Quadt
Venue: Proceedings of the 38th conference on Winter simulation (2006)

We present a scheduling procedure for the wire-bonding operation of a semiconductor assembly facility. The wire-bonding operation typically consists of a large number of unrelated parallel machines and is typically one of the bottlenecks in an assembly facility. The scheduling procedure is able to handle setup times, limited fixtures (clamp&paddles) and non-zero machine ready-times (initial work in progress). It is based on a simulator that generates a schedule and a Simulated Annealing approach to optimize the schedule. Some preliminary results from an implementation in a large assembly facility are given.

Method for polymer hot embossing process development
Authors: Proyag Datta, Jost Goettert
Venue: Microsystem Technologies (2006)

Molding technologies associated with fabricating macro scale polymer components such as injection molding and hot embossing have been adapted with considerable success for fabrication of polymer microparts. While the basic principles of the process remain the same, the precision with which the processing parameters need to be controlled especially in the case of molding high aspect ratio (HAR) polymer microparts into polymer sheets is much greater than in the case of macro scale parts. It is seen that the bulk effects of the mold insert fixture and molding machine have a dominant influence on the molding parameters and that differences in material parameters such as the glass transition temperature (Tg) of polymer sheets are critical for the success and typically differ from sheet to sheet. This makes it very challenging to establish standard processing parameters for hot embossing of sheet polymers. In the course of this paper, a methodology for developing a hot embossing process for HAR microstructures based on known material properties and considering the cumulative behavior of mold, material, and machine will be presented. Using this method force&#x2013;temperature&#x2013;deflection curves were measured with the intent of fine tuning the hot embossing process. Tests were carried out for different materials using a dummy mold insert yielding information that could be directly transferred to the actual mold insert with minimum development time and no risk of damage to the actual microstructures.
Fitting combinations of exponentials to probability distributions: Research Articles
Authors: Daniel Dufresne
Venue: Applied Stochastic Models in Business and Industry (2007)

Two techniques are described for approximating distributions on the positive half-line by combinations of exponentials. One is based on Jacobi polynomial expansions, and the other on the logbeta distribution. The techniques are applied to some well-known distributions (degenerate, uniform, Pareto, lognormal and others). In theory, the techniques yield sequences of combination of exponentials that always converge to the true distribution, but their numerical performance depends on the particular distribution being approximated. An error bound is given in the case the logbeta approximations. Copyright &copy; 2006 John Wiley & Sons, Ltd.
Practical animation of turbulent splashing water
Authors: Janghee Kim, Deukhyun Cha, Byungjoon Chang, Bonki Koo, Insung Ihm
Venue: Proceedings of the 2006 ACM SIGGRAPH/Eurographics symposium on Computer animation (2006)

Despite recent advances in fluid animation, producing small-scale detail of turbulent water still remains challenging. In this paper, we extend the well-accepted particle level set method in an attempt to integrate the dynamic behavior of splashing water easily into a fluid animation system. Massless marker particles that still escape from the main body of water, in spite of the level set correction, are transformed into water particles to represent subcell-level features that are hard to capture with a limited grid resolution. These physical particles are then moved in the air through a particle simulation system that, combined with the level set, creates realistic turbulent splashing. In the rendering stage, the particle's physical properties such as mass and velocity are exploited to generate a natural appearance of water droplets and spray. In order to visualize the hybrid water, represented in both level set and water particles, we also extend a Monte Carlo ray tracer so that the particle agglomerates are smoothed, thickened, if necessary, and rendered efficiently. The effectiveness of the presented technique is demonstrated with several examples of pictures and animations.
Fast continuous collision detection for articulated models
Authors: Stephane Redon, Young J. Kim, Ming C. Lin, Dinesh Manocha
Venue: Proceedings of the ninth ACM symposium on Solid modeling and applications (2004)

We present a novel algorithm to perform continuous collision detection for articulated models. Given two discrete configurations of the links of an articulated model, we use an "arbitrary in-between motion" to interpolate its motion between two successive time steps and check the resulting trajectory for collisions. Our approach uses a three-stage pipeline: (1) dynamic bounding-volume hierarchy (D-BVH) culling based on interval arithmetic; (2) culling refinement using the swept volume of line swept sphere (LSS) and graphics hardware accelerated queries; (3) exact contact computation using OBB-trees and continuous collision detection between triangular primitives. The overall algorithm computes the time of collision, contact locations and prevents any interpenetration between the articulated model with the environment. We have implemented the algorithm and tested its performance on a 2.4 GHz Pentium PC with 1 Gbyte of RAM and a NVIDIA GeForce FX 5800 graphics card. In practice, our algorithm is able to perform accurate and continuous collision detection between articulated models and complex environments at nearly interactive rates.
Design of multicast protocols robust against inflated subscription
Authors: Sergey Gorinsky, Sugat Jain, Harrick Vin, Yongguang Zhang
Venue: IEEE/ACM Transactions on Networking (TON) (2006)

To disseminate data to a heterogeneous body of receivers efficiently, congestion control protocols for IP multicast compose a session from several multicast groups and prescribe guidelines that enable each re ceiver to subscribe to an appropriate subset of the groups. However, a misbehaving receiver can ignore the group subscription rules and inflate its subscription to acquire unfairly high throughput. In this paper, we present the first solution for the problem of inflated subscription. Our design guards access to multicast groups with dynamic keys and consists of two independent components: DELTA (Distribution of ELigibility To Access)-a novel method for in-band distribution of group keys to receivers that are eligible to access the groups according to the congestion control protocol, and SIGMA (Secure Internet Group Management Architecture)-a generic architecture for key-based group access at edge routers. We apply DELTA and SIGMA to derive robust versions of prominent RLM and FLID-DL protocols.

Modelling dendritic solidification with melt convection using the extended finite element method
Authors: Nicholas Zabaras, Baskar Ganapathysubramanian, Lijian Tan
Venue: Journal of Computational Physics (2006)

Dendritic solidification of pure materials from an undercooled melt is studied using the extended finite element method/ level set method for modelling the thermal problem and a volume-averaged stabilized finite element formulation for modelling fluid flow. The extended finite element method using evolving enrichment functions allows accurate modelling of the discontinuous thermal conditions at the moving sharp freezing front thus capturing its motion precisely. The solution of the velocity field in the melt is obtained assuming that the sharp-interface is diffused over the length of two finite elements. The methodology presented is shown to be an effective tool for capturing the interface phenomena and freezing interface growth using a single uniform finite element grid. The whole formulation is packaged into a flexible, modular and parallel library with the ability to incorporate new physics. Comparisons with other numerical methods as well as analytical results emphasize the fidelity of the method in modelling the underlying physical phenomena and growth mechanisms. Various examples of dendritic growth in two- and three-dimensions are presented.

Venue: AI Communications (2001)

We discuss in this paper how the results of the discipline known as Knowledge Management could improve some types of Environmental Systems. In particular we discuss Environmental Decision Support Systems (EDSS). In the last decade, EDSS emerged as a suitable software tool to support control decision&dash;making to maximize the performance of a system and to minimize the negative impact of faults. Knowledge Management in Environmental Decision Support Systems appear as a necessity for EDSS users to place guarantees on the system's behavior but these methodologies are still under&dash;explored. In this paper, a first approach to put forward a Knowledge Management Methodology by identifying the most relevant issues, is introduced and discussed.
