A conjecture in numerical linear algebra
Authors: I. Farkas
Venue: ACM SIGNUM Newsletter (1974)

In cca. Feb. 1971 when Wilkinson visited Toronto, I mentioned the following conjecture to him: Let us assume that we have a general complex matrix, then, the optimal way to determine its eigen system is Householder reduction followed by QR transformation in the sense of numerical analysis. Wilkinson remarked that the conjecture was too vague.

A joint-ONU interval-based dynamic scheduling algorithm for ethernet passive optical networks
Authors: Hassan Naser, Hussein T. Mouftah
Venue: IEEE/ACM Transactions on Networking (TON) (2006)

This paper proposes a new dynamic bandwidth allocation system for Ethernet Passive Optical Networks (EPONs), subject to requirements of fairness, efficiency, and cost. An Optical Line Terminal (OLT)-centric bandwidth allocation model is proposed which employs a credit pooling technique combined with a weighted-share policy to partition the upstream bandwidth among different classes of service, and to prevent Optical Network Units (ONUs) from monopolizing the bandwidth. The OLT-centric model allows global optimization of network resources, a characteristic which is not found in many earlier proposals. Supported by the new bandwidth allocation, the paper proposes a joint-ONU interval-based packet scheduling algorithm, referred to herein as COPS (Class-of-service Oriented Packet Scheduling), that meets the requirements set out above. We compare COPS with another well-known scheduling algorithm which employed a standard priority-based bandwidth sharing. We show that COPS is superior in terms of network utilization and maximum packet delay, with the consequence of an increase in average packet delay for the premium traffic. This drawback is overcome by combining COPS with a rate-based optimization scheme.
Interpreting rate analysis
Authors: Harvey J. Greenberg
Venue: Issue 17 (November 1974) (1974)

Since rate analysis has been discovered by mathematical programmers, it has been misused in recommending one algorithm over another. The primary purpose of this note is to demonstrate this assertion and provide some insight into interpretative rate analysis. Further, I shall describe important uses of rate analysis, namely for acceleration and design of cut-off rules.
Network classless time protocol based on clock offset optimization
Authors: Omer Gurewitz, Israel Cidon, Moshe Sidi
Venue: IEEE/ACM Transactions on Networking (TON) (2006)

Time synchronization is critical in distributed environments. A variety of network protocols, middleware and business applications rely on proper time synchronization across the computational infrastructure and depend on the clock accuracy. The Network Time Protocol (NTP) is the current widely accepted standard for synchronizing clocks over the Internet. NTP uses a hierarchical scheme in order to synchronize the clocks in the network. In this paper we present a novel non-hierarchical peer-to-peer approach for time synchronization termed CTP--Classless Time Protocol. This approach exploits convex optimization theory in order to evaluate the impact of each clock offset on the overall objective function. We define the clock offset problem as an optimization problem and derive its optimal solution. Based on the solution we develop a distributed protocol that can be implemented over a communication network, prove its convergence to the optimal clock offsets and show its properties. For compatibility, CTP may use the packet format and number of measurements used by NTP. We also present methodology and numerical results for evaluating and comparing the accuracy of time synchronization schemes. We show that the CTP outperforms hierarchical schemes such as NTP in the sense of clock accuracy with respect to a universal clock.

Authenticating corrupted photo images based on noise parameter estimation
Authors: Sang-Woong Lee, Ho-Cheol Jung, Bon-Woo Hwang, Seong-Whan Lee
Venue: Pattern Recognition (2006)

Photo image authentication is an interesting and demanding field in the computer vision and image processing community. This research is motivated by its wide range of applications, which include smart card authentication systems, biometric passport systems, etc. In this paper, we propose a method of authenticating corrupted photo images based on noise parameter estimation. The proposed method first generates corrupted images by adjusting the noise parameters in the initial training phase. This set of corrupted images and the noise parameters can be represented by a linear combination of the prototypes of the corrupted images and the noise parameters. In the testing phase, the noise parameters of the corrupted photo image can be estimated with a corrupted image and an original image. Finally, we can make a synthesized photo image from the original photo image using the estimated noise parameters and verify it with the corrupted photo image. The experimental results show that the proposed method can estimate the noise parameters accurately and improve the performance of photo image authentication.

Increased energy efficiency in a Swedish iron foundry through use of discrete event simulation
Authors: Petter Solding, Patrik Thollander
Venue: Proceedings of the 38th conference on Winter simulation (2006)

There is a long lasting debate concerning the rapidly increasing energy prices in Sweden. For industry the prices has increased by roughly 100 percent the last 5 years. This situation has resulted in an extensive energy research and the work of this paper is part of that development. The paper presents a methodology to analyze and reduce the energy use within energy-intensive companies where the Swedish foundries are the main targets. The methodology is tested on a Swedish iron foundry. The paper shows that using specially built simulation models companies can lower their energy costs by planning the production in a more efficient way. The methodology described helps breaking down energy parameters into groups and gives examples of how the simulation model can be built to take energy use into consideration.
An approach to virtual allocation in storage systems
Authors: Sukwoo Kang, A. L. Narasimha Reddy
Venue: ACM Transactions on Storage (TOS) (2006)

This article presents virtual allocation, a scheme for flexible storage allocation. Virtual allocation separates storage allocation from the file system. It employs an allocate-on-write strategy which lets applications fit into the actual usage of storage space, without regard to the configured file system size. This improves flexibility by allowing storage space to be shared across different file systems. This article presents the design of virtual allocation and its evaluation through benchmarks. To illustrate our approach, we implemented a prototype system on PCs running Linux. We present the results from the prototype implementation and its evaluation.

Process conditions in X-ray lithography for the fabrication of devices with sub-micron feature sizes
Authors: Timo Mappes, Sven Achenbach, Juergen Mohr
Venue: Microsystem Technologies (2006)

This article describes the fabrication of polymer structures with lateral dimensions in the sub-micron regime using hard X-rays (&#x03bb;c&#x00a0;&#x2248;&#x00a0;0.4&#x00a0;nm) from the electron storage ring ANKA. Spincoated polymethylmethacrylate (PMMA) grades have been analyzed with respect to development rates and contrast. The contrast has been determined to be constant over a wide dose regime but rapidly decreases for dose values below 1&#x00a0;kJ/cm3. Films with a thickness from 2 to 11&#x00a0;&#x03bc;m have been patterned using a high resolution X-ray mask consisting of 2&#x00a0;&#x03bc;m thick gold absorbers on a suspended 1&#x00a0;&#x03bc;m thick silicon nitride membrane. The fabrication of sub-micron X-ray lithography structures with feature sizes down to 400&#x00a0;nm is confined by the mechanical parameters of the resist material and the process conditions. Surface tension after development limits the achievable aspect ratio of isolated pillars and walls, depending on the actual resist height. PMMA structures have been successfully used as template for electroplating of 1&#x00a0;&#x03bc;m thick gold to demonstrate the fabrication capability of sub-micron scale metal parts.
Simulation of bubbles
Authors: Wen Zheng, Jun-Hai Yong, Jean-Claude Paul
Venue: Proceedings of the 2006 ACM SIGGRAPH/Eurographics symposium on Computer animation (2006)

We present a novel framework based on a continuous fluid simulator for general simulation of realistic bubbles, with which we can handle as many significant dynamic bubble effects as possible. To capture nature of the very thin liquid film of bubbles, we have developed a regional level set method allowing multi-manifold interface tracking. The regional level set method is based on the definitions of regional distance and its five operators, which makes it very easy to implement. We can reconstruct an implicit surface of liquid film with arbitrary thickness from the representation of regional level set functions. To overcome the numerical instability caused by surface tension, we exploit a new semi-implicit surface tension model which is unconditionally stable and makes the simulation of surface tension dominated phenomena much more efficient. An approximated film thickness evolution model is proposed to control the bubble's lifecycle. All these new techniques combine into a general framework that can produce various realistic dynamic effects of bubbles.
A novel gray-based reduced NN classification method
Authors: Chi-Chun Huang
Venue: Pattern Recognition (2006)

In pattern recognition, instance-based learning (also known as nearest neighbor rule) has become increasingly popular and can yield excellent performance. In instance-based learning, however, the storage of training set rises along with the number of training instances. Moreover, in such a case, a new, unseen instance takes a long time to classify because all training instances have to be considered when determining the 'nearness' or 'similarity' among instances. This study presents a novel reduced classification method for instance-based learning based on the gray relational structure. Here, only some training instances in the original training set are adopted for the pattern classification tasks. The relationships among instances are first determined according to the gray relational structure. In the relational structure, the inward edges of each training instance, indicating how many times each instance is considered as the nearest neighbor or neighbors in determining the class labels of other instances can be obtained. This method excludes training instances with no or few inward edges for the pattern classification tasks. By using the proposed instance pruning approach, new instances can be classified with a few training instances. Nine data sets are adopted to demonstrate the performance of the proposed learning approach. Experimental results indicate that the classification accuracy can be maintained when most of the training instances are pruned before learning. Additionally, the number of remained training instances in the proposal presented here is comparable to that of other existing instance pruning techniques.
The visual characteristics of avatars in computer-mediated communication: Comparison of Internet Relay Chat and Instant Messenger as of 2003
Authors: Hye-Seung Kang, Hee-Dong Yang
Venue: International Journal of Human-Computer Studies (2006)

This research focuses on computer-mediated communication where users are represented by a graphical avatar. An avatar represents a user's self-identity and desire for self-disclosure. Therefore, the claim is made that there is a relationship between the characteristics of media and the choice of avatar. This study supports the claim by examining the difference between Internet Relay Chat (IRC) avatars and Instant Messenger (IM) avatars as of 2003 when both media had distinct characteristics and popular avatar service in Korea. Users of IRC are generally anonymous and involved with topic-based group discussions, whereas users of IM are known by their ''real'' names and communicate via one-on-one chitchatting. We found that avatars as symbols for users can have different characteristics in terms of self-identity and self-disclosure in different media. Gender is found to have significant moderation effect on avatar usage, whereas age is shown to have a mixed moderation effect.
Computational investigations of quasirandom sequences in generating test cases for specification-based tests
Authors: Hongmei Chi, Edward L. Jones
Venue: Proceedings of the 38th conference on Winter simulation (2006)

This paper presents work on generation of specification-driven test cases based on quasirandom (low-discrepancy) sequences instead of pseudorandom numbers. This approach is novel in software testing. This enhanced uniformity of quasirandom sequences leads to faster generation of test cases covering all possibilities. We demonstrate by examples that quasirandom sequences can be a viable alternative to pseudorandom numbers in generating test cases. In this paper, we present a method that can generate test cases from a decision table specification more effectively via quasirandom numbers. Analysis of a simple problem in this paper shows that quasirandom sequences achieve better data than pseudorandom numbers, and have the potential to converge faster and so reduce the computational burden. The use of different quasirandom sequences for generating test cases is presented in this paper.
