A Human-Assisted System to Build 3-D Models from a Single Image
Authors: Alexandre R. J. Francois, Gerard G. Medioni
Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

We present a system at the junction between Computer Vision and Computer Graphics, to produce a 3-D model of an object as observed in a single image, with a minimum of high-level interaction from a user.The input to our system is a single image. First, the user points, coarsely, at image features (edges) that are subsequently automatically and reproducibly extracted in real-time. The user then performs a high level labeling of the curves (e.g. limb edge, cross-section) and specifies relations between edges (e.g. symmetry, surface or part).NURBS are used as working representation of image edges. The objects described by the user specified, qualitative relationships are then reconstructed either as a set of connected parts modeled as Generalized Cylinders, or as a set of 3-D surfaces for 3-D bilateral symmetric objects. In both cases, the texture is also extracted from the image.
Applying the equivalent pi circuit to the modeling of hydraulic pressurized lines
Authors: Kang Lin, Keith E. Holbert
Venue: Mathematics and Computers in Simulation (2009)

Pressurized lines, such as water pipelines and hydraulic brake lines, are used for many applications across different industries. Various models focusing on the dynamic pressure behavior of such lines have been developed; however, some representations are either inadequate or difficult to implement. In this paper, existing pressurized line models are first reviewed and a comparison of the relative accuracy among different representations is provided. Moreover, the equivalent pi circuit model developed in electric power engineering is applied to provide an exact representation of a distributed parameter pressurized line. This exact model is compared to multi-lump representations, and its use is demonstrated using examples.
Transient stability of an adaptive sliding-mode load torque observer
Authors: Wirote Sangtungtong, Sarawut Sujitjorn
Venue: Proceedings of the 8th conference on Systems theory and scientific computation (2008)

This article reveals the detailed analysis of the stability of an adaptive sliding-mode load torque observer. Using the Lyapunov's direct method, the stability can be concluded only in some time intervals during transient state. Using the LaSalle's invariance principle, it can be concluded that by the end of the transient state the observer definitely enters the stable steady-state.
Detecting Incorrect Feature Tracking by Affine Space Fitting
Authors: Chika Takada, Yasuyuki Sugaya
Venue: Proceedings of the 3rd Pacific Rim Symposium on Advances in Image and Video Technology (2009)

We present a new method for detecting incorrect feature point tracking. In this paper, we detect incorrect feature point tracking by imposing the constraint that under the affine camera model feature trajectories should be in an affine space in the parameter space. Introducing a statistical model of image noise, we test detected partial trajectories are sufficiently reliable. Then we detect incorrect partial trajectories. Using real video images, we demonstrate that our proposed method can detect incorrect feature point tracking fairly well.

Venue: Proceedings of the 12th International Conference on Extending Database Technology: Advances in Database Technology (2009)

Annotations play a key role in understanding and curating databases. Annotations may represent comments, descriptions, lineage information, among several others. Annotation management is a vital mechanism for sharing knowledge and building an interactive and collaborative environment among database users and scientists. What makes it challenging is that annotations can be attached to database entities at various granularities, e.g., at the table, tuple, column, cell levels, or more generally, to any subset of cells that results from a select statement. Therefore, simple comment fields in tuples would not work because of the combinatorial nature of the annotations. In this paper, we present extensions to current database management systems to support annotations. We propose storage schemes to efficiently store annotations at multiple granularities, i.e., at the table, tuple, column, and cell levels. Compared to storing the annotations with the individual cells, the proposed schemes achieve more than an order-of-magnitude reduction in storage and up to 70% saving in the query execution time. We define types of annotations that inherit different behaviors. Through these types, users can specify, for example, whether or not an annotation is continuously applied over newly inserted data and whether or not an annotation is archived when the base data is modified. These annotation types raise several storage and processing challenges that are addressed in the paper. We propose declarative ways to add, archive, query, and propagate annotations. The proposed mechanisms are realized through extensions to the standard SQL. We implemented the proposed functionalities inside PostgreSQL with an easy to use Excel-based front-end graphical interface.
On the feasibility of dynamic congestion-based pricing in differentiated services networks
Authors: Nan Jin, Scott Jordan
Venue: IEEE/ACM Transactions on Networking (TON) (2008)

Differentiated services can ensure that traffic on some codepoints receives higher quality of service (QoS) than traffic on other codepoints, but without additional mechanisms it cannot target any particular QoS. Congestion-based pricing has been suggested as a method to target QoS in other network architectures. Here, we investigate whether congestion-based pricing can be used to control aggregate traffic into each codepoint by motivating users to choose the codepoints appropriate for each application. We first ask what information needs to be exchanged; we assert that both price and QoS information must be available for users to make decisions. We then ask how effective congestion-based pricing in diffServ can be; we find that it is feasible only for networks with sufficiently high bandwidth to guarantee that QoS can be quickly measured.
IntegraL: Lightweight Link-Based Integration of Heterogeneous Digital Library Collections and Services in the Deep Web
Authors: Min Song, Michael Bieber
Venue: Proceedings of the 2008 10th IEEE Conference on E-Commerce Technology and the Fifth IEEE Conference on Enterprise Computing, E-Commerce and E-Services (2008)

IntegraL is a digital library system demonstrating a lightweight system integration technique for digital library collections and services. Digital library systems generally require integration with minimal or no changes to their code. IntegraL users see a totally integrated environment. They use their digital library system just as before. They also see extra link anchors. Selecting one generates a list of links to relevant meta-information (structural, content-based and knowledge-sharing relationships, and metadata). IntegraL generates the vast majority of supplemental link anchors and meta-information links automatically through the use of relationship rules. This paper presents the concept of meta-information, describes the IntegraL infrastructure and architecture supported by single sign-on authentication middleware, and explains how systems can integrate into the infrastructure. This research’s primary contribution is providing a relatively straightforward, sustainable infrastructure for integrating digital library collections and services.
Particle-based viscoplastic fluid/solid simulation
Authors: Afonso Paiva, Fabiano Petronetto, Thomas Lewiner, Geovan Tavares
Venue: Computer-Aided Design (2009)

Simulations of viscoplastic materials are traditionally governed by continuum mechanics. The viscous behavior is typically modeled as an internal force, defined by diverse quantities. This work introduces a fluid model to simulate the viscoplastic effect of solid materials, such as plastic, wax, clay and polymer. Our method consists in modeling a solid object through a non-Newtonian fluid with high viscosity. This fluid simulation uses the Smoothed Particle Hydrodynamics method and the viscosity is formulated by using the General Newtonian Fluid model. This model concentrates the viscoplasticity in a single parameter. Our results show clear effects of creep, melting, hardening and flowing.
Conventions to Achieve Safer Design and Reduce Catastrophic and Routine Harm to the Environment
Authors: Bruce Moulton
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 02 (2009)

A principle of safe design is that it is preferable for a design to "eliminate"hazards, rather than "manage"them. Some of the principles of safe design appear to be enacted in Australian legislation. In addition, tort law can hold designers liable for harm attributable to their actions and inactions. Designers' desire to avoid litigation most likely serves to curb extreme examples of reckless and harmful unsafe design. However, in many instances, it seems that designers who bring about "routine" harm tend not to be held liable. Nevertheless, when litigation does occur, the court ordinarily asks what a reasonable person in the position of the designer would have foreseen and done. In this context, it is proposed that safe design conventions may play two roles. First, such conventions may serve to influence designers in all countries to appreciate and adopt principles of safe design. Second, such conventions may help to provide courts with guidance as to what is expected of a reasonable person in the position of a designer.
Semi-synchronous transductions
Authors: Vince B&#x00e1;r&#x00e1;ny
Venue: Acta Informatica (2009)

Semi-synchronously rational relations generalise synchronised rational relations in a natural way. We discuss here some of their basic properties, among them a &#x201c;Cobham&#x2013;Semenov-like&#x201d; dichotomy theorem. Our main result is a characterisation of bijective semi-synchronously rational transductions as those bijections mapping regular relations to regular ones and non-regular relations to non-regular ones.
BlobFinder, a tool for fluorescence microscopy image cytometry
Authors: A. Allalou, C. Wählby
Venue: Computer Methods and Programs in Biomedicine (2009)

Images can be acquired at high rates with modern fluorescence microscopy hardware, giving rise to a demand for high-speed analysis of image data. Digital image cytometry, i.e., automated measurements and extraction of quantitative data from images of cells, provides valuable information for many types of biomedical analysis. There exists a number of different image analysis software packages that can be programmed to perform a wide array of useful measurements. However, the multi-application capability often compromises the simplicity of the tool. Also, the gain in speed of analysis is often compromised by time spent learning complicated software. We provide a free software called BlobFinder that is intended for a limited type of application, making it easy to use, easy to learn and optimized for its particular task. BlobFinder can perform batch processing of image data and quantify as well as localize cells and point like source signals in fluorescence microscopy images, e.g., from FISH, in situ PLA and padlock probing, in a fast and easy way.

Complex Gaussian quadrature of oscillatory integrals
Authors: Alfredo Dea&#x00f1;o, Daan Huybrechs
Venue: Numerische Mathematik (2009)

We construct and analyze Gauss-type quadrature rules with complex- valued nodes and weights to approximate oscillatory integrals with stationary points of high order. The method is based on substituting the original interval of integration by a set of contours in the complex plane, corresponding to the paths of steepest descent. Each of these line integrals shows an exponentially decaying behaviour, suitable for the application of Gaussian rules with non-standard weight functions. The results differ from those in previous research in the sense that the constructed rules are asymptotically optimal, i.e., among all known methods for oscillatory integrals they deliver the highest possible asymptotic order of convergence, relative to the required number of evaluations of the integrand.

Authors: Michael Awoleye, Adeniran Oluwaranti, Willie Siyanbola, Rotimi Adagunodo
Venue: Proceedings of the 2nd International Conference on Theory and Practice of Electronic Governance (2008)

Several assessment studies on penetration and adoption of computer and the internet have shown that these tools are beginning to change the way citizens interact with one another and also with their governments and vice-versa [1]. An assessment from two states in the South Western part of Nigeria regarding the awareness, use and sustainability of e-Governance in Nigeria was carried out. The perspectives of the government staff as well as other users (non-government staff) were assessed. It was found that 68% of both government employees (GE) and non-government employees (NGEs) are aware of e-Governance in the states, and the governments have achieved this high rate of awareness by means of mass media (30%). Computer literacy amongst employees is put at 19 users out of every 20, and 52% of those that are computer literate have over 3yrs experience in using the computer. Also, 76.6% are reported to have access to the Internet and only 31.3% of those that have access to the Internet have access points in their offices. Proficiency about the use of e-Governance resources was also tested, it was found that about 50% of the users are proficient and about 35% of them use the Internet on a daily basis. Challenges about the e-Governance resource were also discussed and appropriate policy directions are advanced for a better use and its sustainability.

This paper discusses security and privacy issues in AMUNETs - the amateur radio computer networks at educational institutions and elsewhere. The paper presents results of the recent experiments, which intention was to test security in accessing the amateur radio e-mail servers and digital radio relay systems. This work suggests various methods which aim is to bridge the gap between the safety and comfort in regular end user's activities within the amateur radio digital infrastructure. There are many opportunities in available safety measures, which support the integrity of user's and system administrator's credentials.
A study of secondary spectrum use using agent-based computational economics
Authors: Arnon Tonmukayakul, Martin B. Weiss
Venue: Netnomics (2008)

Wireless communication relies on access to the radiocommunications spectrum. A series of high-priced spectrum auctions has indicated that there is a scarcity or an inefficient use of spectrum resources. This paper presents an Agent-based Computational Economics (ACE) model designed to study the secondary use spectrum market, which improves spectrum usage by allowing incumbent spectrum users to lease unused portions of their assigned spectrum to third parties who could put them to a better use. In this paper, we are particularly interested in the conditions under which such a market is likely to emerge.
Statistical modeling and analysis of chip-level leakage power by spectral stochastic method
Authors: Ruijing Shen, Ning Mi, Sheldon X.-D. Tan, Yici Cai, Xianlong Hong
Venue: Proceedings of the 2009 Asia and South Pacific Design Automation Conference (2009)

In this paper, we present a novel statistical full-chip leakage power analysis method. The new method can provide a general framework to derive the full-chip leakage current or power in a closed form in terms of the variational parameters, such as the channel length, the gate oxide thickness, etc. It can accommodate various spatial correlations. The new method employs the orthogonal polynomials to represent the variational gate leakages in a closed form first, which is generated by a fast multi-dimensional Gaussian quadrature method. The total leakage currents then are computed by simply summing up the resulting orthogonal polynomials (their coefficients). Unlike many existing approaches, no grid-based partitioning and approximation are required. Instead, the spatial correlations are naturally handled by orthogonal decompositions. The proposed method is very efficient and it becomes linear in the presence of strong spatial correlations. Experimental results show that the proposed method is about 10x faster than the recently proposed method [4] with constant better accuracy.

Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

Shake2Talk is a mobile messaging system that allows users to send sounds and tactile sensations to one another via their mobile phones. Messages are created through gestures and then sent to the receiver's phone where they play upon arrival. This paper reports a study of the Shake2Talk system in use by six couples, and begins to uncover the types of messaging practices that occur, and the values and meanings that users ascribe to these messages.

Resource Allocation in Bounded Degree Trees
Authors: Reuven Bar-Yehuda, Michael Beder, Yuval Cohen, Dror Rawitz
Venue: Algorithmica (2009)

We study the bandwidth allocation problem (bap) in bounded degree trees. In this problem we are given a tree and a set of connection requests. Each request consists of a path in the tree, a bandwidth requirement, and a weight. Our goal is to find a maximum weight subset S of requests such that, for every edge e, the total bandwidth of requests in S whose path contains e is at most 1. We also consider the storage allocation problem (sap), in which it is also required that every request in the solution is given the same contiguous portion of the resource in every edge in its path. We present a deterministic approximation algorithm for bap in bounded degree trees with ratio . Our algorithm is based on a novel application of the local ratio technique in which the available bandwidth is divided into narrow strips and requests with very small bandwidths are allocated in these strips. We also present a randomized (2+&epsilon;)-approximation algorithm for bap in bounded degree trees. The best previously known ratio for bap in general trees is 5. We present a reduction from sap to bap that works for instances where the tree is a line and the bandwidths are very small. It follows that there exists a deterministic 2.582-approximation algorithm and a randomized (2+&epsilon;)-approximation algorithm for sap in the line. The best previously known ratio for this problem is 7.
Adopting the Drowsy Technique for Instruction Caches: A Soft Error Perspective
Authors: Soong Hyun Shin, Sung Woo Chung, Eui-Young Chung, Chu Shik Jhon
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

As technology scales down, leakage energy accounts for a greater proportion of total energy. Applying the drowsy technique to a cache, is regarded as one of the most efficient techniques for reducing leakage energy. However, it increases the Soft Error Rate (SER), thus, many researchers doubt the reliability of the drowsy technique. In this paper, we show several reasons why the instruction cache can adopt the drowsy technique without reliability problems. First, an instruction cache always stores read-only data, leading to soft error recovery by re-fetching the instructions from lower level memory. Second, the effect of the re-fetching caused by soft errors on performance is negligible. Additionally, a considerable percentage of soft errors can occur without harming the performance. Lastly, unrecoverable soft errors can be controlled by the scrubbing method. The simulation results show that the drowsy instruction cache rarely increases the rate of unrecoverable errors and negligibly degrades the performance.
