A springboard for data processing education in Oklahoma
Authors: Denise A. Pierce
Venue: Proceedings of the May 6-10, 1974, national computer conference and exposition (1974)

Certainly the problems expressed in the preceding presentations have not been foreign to Oklahoma. Oklahoma has realized the vast need for a marriage between education and industry, particularly in the area of data processing where no traditional curriculum patterns exist and where there are no established career paths for data processing instructors to follow. Oklahoma had an additional need, however, the cooperation between the various State agencies in using a "system approach" to improve education, and more specifically data processing education. The existing bureaucratic machinery allowed a certain degree of amalgamation, but the gap had not been totally closed. This paper will seek to outline the framework of the cooperation between the State agencies, to discuss the state-wide teleprocessing system, to comment on the more usual types of involvements in data processing education, and close by discussing what Oklahoma is using as a springboard for accomplishing projects and meeting expressed needs.

QA Builder: A Visual Toolkit for Building Multimedia Knowledge-based Systems with Immediate Feedback
Venue: Proceedings of the 1996 International Conference on Multimedia Computing and Systems (1996)

QA Builder is a toolkit for building interactive knowledge-based systems for domains in which the domain knowledge can be expressed as a sequence of questions and answers. It integrates knowledge acquisition, knowledge-base validation, multimedia authoring, and user interface design and validation in a unifying framework. It is unique in that it treats non-textual information such as video, audio, and graphical images as integral parts of the domain knowledge, and that it provides authors with immediate feedback. This paper describes the QA Builder with an emphasis on the object-oriented visual editors. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

COQUINA: Content-Queryable Image and Signal Archives
Authors: Wen-Chen Hu, Mark S. Schmalz, Gerhard X. Ritter
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

This research proposes an image representation, called a line string, encodes an image via a string of linear skeleton, and an image matching method, i.e., finding a longest approximate common subsequence of two line strings. An image retrieval system is constructed based on the above methods. Experimental results show any image in the system can be precisely retrieved as long as each image has a unique image string.
On stress aware active area sizing, gate sizing, and repeater insertion
Authors: Ashutosh Chakraborty, David Z. Pan
Venue: Proceedings of the 2009 international symposium on Physical design (2009)

Enormous technical and economic challenges facing technology scaling has rendered strain engineering techniques as the critical enabler of high performance designs in sub-$100$nm geometries. One of these techniques, source/drain (S/D) SiGe, has an interesting property that the mobility of the device is dependent on the size of active area (AA) surrounding it. To exploit this phenomenon for higher performance, a circuit designer needs first order and computationally tractable transistor level models. This paper provides the first AA sizing dependent RC switch level model of a logic gate which can be readily used by circuit designers. We derive the methodology to optimally use AA sizing for some common cells such as NAND, NOR and INV. For the first time, we formulate a convex optimization problem for concurrent AA and gate sizing problem for performance optimization and solve it optimally. We also analytically solve AA sizing aware optimal repeater insertion problem for dealing with the menace of long global interconnects in modern chip design. Experimental results demonstrate that our methodology can reduce inter-chip long global interconnect delay by 9% and inter-module gate delays by 10% with only 11% increase in dynamic power dissipation.
Wavelet Based Multipurpose Color Image Watermarking by Using Dual Watermarks with Human Vision System Models
Authors: Min-Jen Tsai, Chih-Wen Lin
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

In this study, we propose a complete architecture based on digital watermarking techniques to solve the issue of copyright protection and authentication for digital contents. We apply visible and semi-fragile watermarks as dual watermarks where visible watermarking is used to establish the copyright protection and semi-fragile watermarking authenticates and verifies the integrity of the watermarked image. In order to get the best tradeoff between the embedding energy of watermark and the perceptual translucence for visible watermark, the composite coefficients using global and local characteristics of the host and watermark images in the discrete wavelet transform (DWT) domain is considered with Human Vision System (HVS) models. To achieve the optimum noise reduction of the visibility thresholds for HVS in DWT domain, the contrast-sensitive function (CSF) and noise visible function (NVF) of perceptual model is applied which characterizes the global and local image properties and identifies texture and edge regions to determine the optimal watermark locations and strength at the watermark embedding stage. In addition, the perceptual weights according to the basis function amplitudes of DWT coefficients is fine tuned for the best quality of perceptual translucence in the design of the proposed watermarking algorithm. Furthermore, the semi-fragile watermark can detect and localize malicious attack effectively yet tolerate mild modifications such as JPEG compression and channel additive white Gaussian noise (AWGN). From the experimental results, our proposed technique not only improves the PSNR values and visual quality than other algorithms but also preserves the visibility of the watermark visible under various signal processing and advanced image recovery attacks.
A new algorithm of region labeling based on improved RLE connectivity analysis
Authors: Tao Hu, Baoping Guo, Xuan Guo
Venue: Proceedings of the 2008 International Conference on Advanced Infocomm Technology (2008)

A new data structural frame of RLE associated indirectly with objects is introduced to make two group RLEs with different object index the same object index just by changing any one RLE's object dual index of one group, which can solve efficiently the problem of RLE labeling conflict in classic RLE connectivity analysis algorithms, and an efficient region labeling algorithm based on improved RLE connectivity analysis is designed to fulfill RLE labeling just by scanning image data once. The algorithm decreases the complexity and is easy to implement with high performance in comparison with classic algorithms.

Authors: Tsung-Yi Ho
Venue: Integrated Circuit and System Design. Power and Timing Modeling, Optimization and Simulation: 18th International Workshop, PATMOS 2008, Lisbon, Portugal, September 10-12, 2008. Revised Selected Papers (2009)

As technology advances into the nanometer territory, the interconnect delay has become a first-order effect on chip performance. To handle this effect, the X-architecture has been proposed for high-performance integrated circuits. In this paper, we present a performance-driven multilevel framework for the X-based full-chip router. To fully consider performance-driven routing and take advantage of the X-architecture, we apply a novel multilevel routing framework, which adopts a four-stage technique of a trial routing stage, followed by a top-down uncoarsening stage, with an intermediate track routing stage, and then followed by a bottom-up coarsening stage. Compared with the state-of-the-art work, we achieve 100% routing completion for all circuits while reduced the net delay.

Authors: Shampa Paul, Kaushalesh Lal
Venue: Proceedings of the 2nd International Conference on Theory and Practice of Electronic Governance (2008)

Information and Communication Technology (ICT) in government agencies as well as educational and research institutions facilitates an efficient, speedy and transparent dissemination of information to the public and other agencies for performance of governments' administrative activities. The importance of ICT in governance has been recognised the world over. Electronic governance (e-governance) highlights several elements of good governance such as transparency, accountability, participation, social integration, public financial management reforms and development. This study is based on personal interview of selected representatives of the Government of National Capital Territory of Delhi and review of e-Governance initiatives taken by the government. The findings of this study highlight the role of Internet, particularly the World Wide Web (WWW), which has made it easier for citizens to locate and download official information and to conduct transactions. We conclude that e-Governance needs to be integrated into the broader public management framework so as to make a substantial change in the government to citizen (G2C) relationship.

So this paper is helpful for the choosing and adjustment of PSO parameters in practical application.
A PIC method for solving a paraxial model of highly relativistic beams
Authors: F. Assous, F. Tsipis
Venue: Journal of Computational and Applied Mathematics (2009)

Solving the Vlasov-Maxwell problem can lead to very expensive computations. To construct a simpler model, Laval et al. [G. Laval, S. Mas-Gallic, P.A. Raviart, Paraxial approximation of ultrarelativistic intense beams, Numer. Math. 69 (1) (1994) 33-60] proposed to exploit the paraxial property of the charged particle beams, i.e the property that the particles of the beam remain close to an optical axis. They so constructed a paraxial model and performed its mathematical analysis. In this paper, we investigate how their framework can be adapted to handle the axisymmetric geometry, and its coupling with the Vlasov equation. First, one constructs numerical schemes and error estimates results for this discretization are reported. Then, a Particle In Cell (PIC) method, in the case of highly relativistic beams is proposed. Finally, numerical results are given. In particular, numerical comparisons with the Vlasov-Poisson model illustrate the possibilities of this approach.
Visual Longitudinal and Lateral Driving Assistance in the Head-Up Display of Cars
Authors: Marcus Tonnis, Christian Lange, Gudrun Klinker
Venue: Proceedings of the 2007 6th IEEE and ACM International Symposium on Mixed and Augmented Reality (2007)

Most car accidents occur due to longitudinal collisions or lane departure. We assume that the number of such accidents can be reduced, if the driver knows more precisely, where the car is heading and at which distance it can stop. To provide drivers with this kind of anticipation, we have developed two Augmented Reality based visualization schemes for longitudinal and lateral driver assistance in the Head-Up Display (HUD) of cars. One presentation scheme indicates the braking distance by a virtual bar on the road. The second scheme adds the visualization of a drive-path between the car and the bar, zoning the entire region that the car will pass before coming to a complete halt. We have tested both schemes in a driving simulator in comparison to a baseline without visual assistance. Our results show, among other findings, that the bar is preferred, that it supports driving performance and that it does not increase mental workload.

Information importance of predictors: Concept, measures, Bayesian inference, and applications
Authors: J. J. Retzer, E. S. Soofi, R. Soyer
Venue: Computational Statistics Data Analysis (2009)

The importance of predictors is characterized by the extent to which their use reduces uncertainty about predicting the response variable, namely their information importance. The uncertainty associated with a probability distribution is a concave function of the density such that its global maximum is a uniform distribution reflecting the most difficult prediction situation. Shannon entropy is used to operationalize the concept. For nonstochastic predictors, maximum entropy characterization of probability distributions provides measures of information importance. For stochastic predictors, the expected entropy difference gives measures of information importance, which are invariant under one-to-one transformations of the variables. Applications to various data types lead to familiar statistical quantities for various models, yet with the unified interpretation of uncertainty reduction. Bayesian inference procedures for the importance and relative importance of predictors are developed. Three examples show applications to normal regression, contingency table, and logit analyses.
Revenue generation for truthful spectrum auction in dynamic spectrum access
Authors: Juncheng Jia, Qian Zhang, Qin Zhang, Mingyan Liu
Venue: Proceedings of the tenth ACM international symposium on Mobile ad hoc networking and computing (2009)

Spectrum is a critical yet scarce resource and it has been shown that dynamic spectrum access can significantly improve spectrum utilization. To achieve this, it is important to incentivize the primary license holders to open up their under-utilized spectrum for sharing. In this paper we present a secondary spectrum market where a primary license holder can sell access to its unused or under-used spectrum resources in the form of certain fine-grained spectrum-space-time unit. Secondary wireless service providers can purchase such contracts to deploy new service, enhance their existing service, or deploy ad hoc service to meet flash crowds demand. Within the context of this market, we investigate how to use auction mechanisms to allocate and price spectrum resources so that the primary license holder's revenue is maximized. We begin by classifying a number of alternative auction formats in terms of spectrum demand. We then study a specific auction format where secondary wireless service providers have demands for fixed locations (cells). We propose an optimal auction based on the concept of virtual valuation. Assuming the knowledge of valuation distributions, the optimal auction uses the Vickrey-Clarke-Groves (VCG) mechanism to maximize the expected revenue while enforcing truthfulness. To reduce the computational complexity, we further design a truthful suboptimal auction with polynomial time complexity. It uses a monotone allocation and critical value payment to enforce truthfulness. Simulation results show that this suboptimal auction can generate stable expected revenue.

Augmenting motion sensing to improve detection of periods of unusual inactivity
Authors: Jenny Weisenberg, Paul Cuddihy, Vrinda Rajiv
Venue: Proceedings of the 2nd International Workshop on Systems and Networking Support for Health Care and Assisted Living Environments (2008)

Two sensing options are examined for their potential to improve the sensitivity of a system that detects periods of inactivity in the homes of elderly persons. A previous prototype used passive infrared motion sensors and door sensors combined with a learning algorithm to detect periods of unusual inactivity such as late wake-ups or the aftermath of a fall. This system worked as intended but suffered from low sensitivity, especially at nighttime, since the motion sensors were not able to distinguish a fall in the bedroom from a person getting into bed. Experiments with a worn accelerometer and with bed and chair occupancy sensors suggest that both can dramatically improve system sensitivity. The optimal solution may depend on the users' activity level, living area size, and willingness to wear a device.
The HighspectJ framework
Authors: Oren Mishali, Shmuel Katz
Venue: Proceedings of the 8th workshop on Aspects, components, and patterns for infrastructure software (2009)

AspectJ pointcuts relate to a specific execution point in the program and thus AspectJ is not capable of naturally expressing high-level events that are the culmination of a series of more basic events. Yet, there is a real need for expressing such events when dealing with domains having terminology at a level of abstraction higher than the program's code, e.g., software process support, usability evaluation of user interfaces, or detecting illegal banking practices. Here, we present a framework called HighspectJ that provides a structured AspectJ-based solution for defining and utilizing high-level events. The framework treats an event as a first-class object, separates between the identification and the treatment of the event, and facilitates definition of events in layers, where higher level events are defined in terms of lower level ones. In addition, definition and reuse of high-level events using aspects is facilitated by an event repository which contains event building blocks. The framework is described process support is given.
Macro-informatics of cognition and its application for design
Authors: Yoshiki Ujiie, Yoshiyuki Matsuoka
Venue: Advanced Engineering Informatics (2009)

This paper describes Macro-informatics of cognition that is the guideline for mathematical formulation of macroscopic feature. The macroscopic feature emerges from the total of shape elements, and the feature is important in the styling design. The mathematical formulation of macroscopic feature is difficult using conventional microscopic shape information such as dimension and curvature. In this paper, for formulation of macroscopic feature, the importance of ''condition'' that is various physical elements in the circumstance is mentioned. Moreover, this paper describes the mathematical formulation of macroscopic feature ''complexity,'' and its application for design. The formulation consists of curvature integration and multi-resolution representation. In application, shape generation method based on a genetic algorithm is introduced.
