Authors: M. A. Dyrud
Venue: Proceedings of the Frontiers in Education Conference, on 1995. Proceedings., 1995 - Volume 02 (1995)

Since the advent of relatively inexpensive desktop publishing software, document design has become increasingly important. Generally speaking, document design refers to the physical arrangement of text and graphics on the page to maximize reader comprehension. This paper discusses design guidelines educators can use to format their assignment instructions. The purpose of formatting is to avoid students' misinterpretation of the assignment and to receive more readable papers. Topics covered are design awareness and formatting tips on using headings, chunking information, and using special features. The ACM Portal is published by the Association for Computing Machinery.

Now for the laboratory experience! The view from four different undergraduate computer science curricula
Authors: J. C. Prey
Venue: Proceedings of the 28th Annual Frontiers in Education - Volume 03 (1998)

There is much discussion about the undergraduate computer science curriculum. With the rapid changes in computer science, the need to stay current is mandatory while the ability to develop and implement a contemporary undergraduate curriculum is extremely time-consuming and costly. Four schools have each developed a different model to undergraduate computer science education. Each school believes the work done has been successfully implemented at the respective institutions. They also believe that these works can be successfully adapted by others. An overview is given of the laboratory models and topics developed for a laboratory activity.
Optimal edge enhancement based on edge patterns and fuzzy logic
Authors: J. Khazaai, M. Z. Atashbar
Venue: Integrated Computer-Aided Engineering (2002)

The major problem of image edge detection is finding the edge pixels which have the similar intensity with background. Finding an appropriate thresholding technique to result an efficient edge is difficult. Most existing edge detection algorithms are dependent to the method of thresholding. This is the central idea of this paper in which we define edge occurrences for the intensity (monochrome) images using fuzzy sets to diminish the above mentioned problems. Edge characteristic functions are proposed for detecting edge pixels within a desired block of an (intensity and binary) image based on quadruple child windowing and binary edge patterns. We called these functions QCW-ECF. Fuzzy theory has been also applied to extend the QCW-ECF algorithm to the FQCW-ECF algorithm for edge detection within a block of a fuzzy intensity image. The (F)QCW-ECF algorithm results in a degree of edginess concerning the middle pixel of the processing block. Edge detection algorithm, FQCW-ECF, based on fuzzy logic with tunable membership functions would be an effective solution for the above mentioned problems. Cyclic coordinate algorithms are adapted to train the FQCW-ECF algorithm so as to minimize a desire performance index via tuning the membership functions of the fuzzy logic system.

Venue: Proceedings of the 40th Annual Hawaii International Conference on System Sciences (2007)

Building on state-of-the-art techniques for forecasting future developments in technology, business, economics, and other areas of human endeavor, we describe a novel methodology for adaptive contingency planning at the strategic initiative level. Complementing normal business planning that uses a schedule based on predictions tied to dates in the future, we use a new kind of early warning signal called a signpost to trigger the execution of corresponding new recommended actions.
A high-accurate Chinese-English NE backward translation system combining both lexical information and web statistics
Authors: Conrad Chen, Hsin-Hsi Chen
Venue: Proceedings of the COLING/ACL on Main conference poster sessions (2006)

Named entity translation is indispensable in cross language information retrieval nowadays. We propose an approach of combining lexical information, web statistics, and inverse search based on Google to backward translate a Chinese named entity (NE) into English. Our system achieves a high Top-1 accuracy of 87.6%, which is a relatively good performance reported in this area until present.

Endangered guitar
Authors: Hans Tammen
Venue: Proceedings of the 7th international conference on New interfaces for musical expression (2007)

The Endangered Guitar is a journey through the land of unending sonic operations and an infinite index of metals. A mix of formal awareness and improvisation produces rapid-fire juxtapositions of radically contrastive and fascinating sounds. Like yanked out tape measures violently squished against the strings to turn out tortured noise scrapings and bizarre textures; but also spektral processing to create quiet pulses and gentle atmospheres...

An Efficient Optical Switch Architecture with Controlled Latency for GRID Networks
Authors: Theofanis G. Orphanoudakis, Andreas Drakos, Chris Matrakidis, Christina (Tanya) Politi, Alexandros Stavdas
Venue: Proceedings of the Third International Conference on Networking and Services (2007)

In this paper we evaluate a hybrid optoelectronic switch architecture, which can be used under Optical Burst Switching (OBS) or even Optical Packet Switching (OPS) schemes. The proposed architecture incorporates electronic switching equipment to a limited degree utilizing the large buffering capacity available only by means of electronic subsystems. This hybrid architecture achieves efficient utilization of optical network resources, which can be assigned dynamically in small time scales, limiting loss probability with controlled average latency. Thus, the proposed switch architecture is suitable for critical networking applications with high capacity and dynamically changing requirements like GRID networking.
Reclaiming network-wide visibility using ubiquitous endsystem monitors
Authors: Evan Cooke, Richard Mortier, Austin Donnelly, Paul Barham, Rebecca Isaacs
Venue: Proceedings of the annual conference on USENIX '06 Annual Technical Conference (2006)

Network-centric tools like NetFlow and security systems like IDSes provide essential data about the availability, reliability, and security of network devices and applications. However, the increased use of encryption and tunnelling has reduced the visibility of monitoring applications into packet headers and payloads (e.g. 93% of traffic on our enterprise network is IPSec encapsulated). The result is the inability to collect the required information using network-only measurements. To regain the lost visibility we propose that measurement systems must themselves apply the end-to-end principle: only endsystems can correctly attach semantics to traffic they send and receive. We present such an end-to-end monitoring platform that ubiquitously records per-flow data and then we show that this approach is feasible and practical using data from our enterprise network.
An experimental setting to measure contextual perception of embodied conversational agents
Authors: Michael Lankes, Regina Bernhaupt, Manfred Tscheligi
Venue: Proceedings of the international conference on Advances in computer entertainment technology (2007)

We introduce an experimental setting to observe and measure the perception of facial expression performed by embodied conversational agents (ECAs). The experimental set-up enables to measure the implications of embodied conversational agents invarious contextual settings. We developed a matrix, distinguishing three types of stimuli dimensions (simultaneous, sequential, adaptive) and three contextual configurations. The aim of the study is to establish an experimental framework to analyze subjects' emotional status in different context dimensions. The experimental setting helps to close a gap in the intersection of affective computing and embodied conversational agents.

Two years with TkMan: lessons and innovations or, everything I needed to know about Tcl/Tk I learned from TkMan
Authors: Thomas A. Phelps
Venue: Proceedings of the 3rd Annual USENIX Workshop on Tcl/Tk - Volume 3 (1995)

Among Tcl/Tk applications, TkMan is unusual. Whereas Tcl was written to glue together C functions, TkMan is written entirely in Tcl. And TkMan is the beneficiary of years of battle testing by 1000s of users on every flavor of UNIX. The extreme position created by the demands of this large, diverse audience and the (self-imposed) limitation of remaining strictly within Tcl brought to the fore a severe set of implementation issues, and provoked a variety of solutions ranging from general methods to a low-level bag of tricks with regard to speeding up Tcl scripts, exploiting Tcl as its own scripting language, configuring applications and interoperating with other tools. Although developed to meet these particular, extreme requirements, most of the resulting solutions can be broadly applied, and this paper shares this lore with the aim of helping other authors develop elegant, efficient and robust Tcl/Tk-based applications.
Stochastic construction of optimal linear channel precoders for random channels
Authors: J. H. Manton
Venue: Proceedings of the The 8th International Conference on Communication Systems - Volume 01 (2002)

Redundant linear precoders improve the reliability of digital communications over frequency selective fading channels by spreading the spectrum of each transmitted block, thus reducing the detrimental effects of channel spectral nulls. The design of optimal precoders under the simplifying assumption that the channel is known has already been studied in the literature. However, the design of optimal precoders for random (i.e., unknown) channels is an unresolved issue. This paper demonstrates that stochastic optimisation algorithms are a natural and effective solution to the optimal precoder design problem for random channels.
Error estimators for advection-reaction-diffusion equations based on the solution of local problems
Authors: Rodolfo Araya, Edwin Behrens, Rodolfo Rodríguez
Venue: Journal of Computational and Applied Mathematics (2007)

This paper deals with a posteriori error estimates for advection-reaction-diffusion equations. In particular, error estimators based on the solution of local problems are derived for a stabilized finite element method. These estimators are proved to be equivalent to the error, with equivalence constants eventually depending on the physical parameters. Numerical experiments illustrating the performance of this approach are reported.
Fixed-lag blind equalization and sequence estimation in digital communications systems using sequential importance sampling
Authors: T. C. Clapp
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1999. on 1999 IEEE International Conference - Volume 05 (1999)

We present methods for fixed-lag smoothing using sequential importance sampling on a discrete non-linear, non-Gaussian state space system with unknown parameters. Our particular application is in the field of digital communication systems. Each input data point is taken from a finite set of symbols. We represent the transmission media as a fixed filter with a finite impulse response (FIR), hence a discrete state-space system is formed. Conventional Markov chain Monte Carlo techniques such as the Gibbs sampler are unsuitable for this task because they can only perform processing on a batch of data. Data arrives sequentially, so it would seem sensible to process it in this way. In addition, many communication systems are interactive, so there is a maximum level of latency that can be tolerated before a symbol is decoded. We demonstrate this method by simulation and compare its performance to existing techniques.
Spatial Multidimensional Sequence Clustering
Authors: Ira Assent, Ralph Krieger, Boris Glavic, Thomas Seidl
Venue: Proceedings of the Sixth IEEE International Conference on Data Mining - Workshops (2006)

Measurements at different time points and positions in large temporal or spatial databases requires effective and efficient data mining techniques. For several parallel measurements, finding clusters of arbitrary length and number of attributes, poses additional challenges. We present a novel algorithm capable of finding parallel clusters in different structural quality parameter values for river sequences used by hydrologists to develop measures for river quality improvements.
On the use of residual cepstrum in speech recognition
Authors: Jialong He
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1996. on Conference Proceedings., 1996 IEEE International Conference - Volume 01 (1996)

In speech recognition based on LPC analysis the prediction residues are usually ignored, only the LPC-derived cepstral coefficients (LPCC) are used to compose feature vectors. In this study, a number of parameters (called the residual cepstrum or RCEP) were calculated from these residues and their effectiveness for speech recognition was evaluated. It was shown that the RCEP do contain useful information, in particular, they are complementary to the LPCC. In an evaluation experiment, if the LPCC were used jointly with a few RCEP coefficients, the recognition rate of the English E-set letters was improved from 54% to 67% and from 69% to 71% by the use of HMMs based recognizer and the DTW based recognizer, respectively. In addition, Mel-scaled FFT based cepstrum (MFCC) was found to be superior to LPCC.

Venue: Proceedings of the 30th Annual Frontiers in Education - Volume 02 (2000)

This paper focuses on recent developments in software engineering accreditation and criteria, how universities are responding to these issues, and how industry views these developments. An earlier panel at FIE'99 addressed the need for and the relevance of software engineering accreditation guidelines. This paper moves to the next stage of discussion and evolution. Additionally, implications of license of software engineers are addressed.
A technique to prove parameter-uniform convergence for a singularly perturbed convection-diffusion equation
Authors: E. O'Riordan, G. I. Shishkin
Venue: Journal of Computational and Applied Mathematics (2007)

A priori parameter explicit bounds on the solution of singularly perturbed elliptic problems of convection-diffusion type are established. Regular exponential boundary layers can appear in the solution. These bounds on the solutions and its derivatives are obtained using a suitable decomposition of the solution into regular and layer components. By introducing extensions of the coefficients to a larger domain, artificial compatibility conditions are not imposed in the derivation of these decompositions.
A two-microphone adaptive broadband array for hearing aids
Authors: E. D. McKinney
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1996. on Conference Proceedings., 1996 IEEE International Conference - Volume 02 (1996)

We derive a two-microphone directional and adaptive broadband array for use in hearing aids. The array contains only two directional microphones to satisfy the cosmetic constraints which are most likely to be accepted by hearing aid wearers. Our proposed processing method is a modification of Widrow (1975) et al.'s narrowband MMSE algorithm which does not generate a reference signal. The required frequency separation is performed using a multirate filter bank. The distance between two microphones is 12 cm. When the signals are split into four narrower bands, an SNR improvement of 9.2 dB and an intelligibility-weighted directivity index of 8.9 dB are obtained. Only 8 weights (2 for each band) need to be updated and thus the approach is much simpler when compared with other methods.
On the enumeration of certain weighted graphs
Authors: Miklós Bóna, Hyeong-Kwan Ju, Ruriko Yoshida
Venue: Discrete Applied Mathematics (2007)

We enumerate weighted simple graphs with a natural upper bound condition on the sum of the weight of adjacent vertices. We also compute the generating function of the numbers of these graphs, and prove that it is a rational function. In particular, we show that the generating function for connected bipartite simple graphs is of the form p"1(x)/(1-x)^m^+^1. For nonbipartite simple graphs, we get a generating function of the form p"2(x)/(1-x)^m^+^1(1+x)^l. Here m is the number of vertices of the graph, p"1(x) is a symmetric polynomial of degree at most m, p"2(x) is a polynomial of degree at most m+l, and l is a nonnegative integer. In addition, we give computational results for various graphs.
Adaptive window in the PWVD for the IF estimation of FM signals in additive Gaussian noise
Authors: B. Barkat
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1999. on 1999 IEEE International Conference - Volume 03 (1999)

The peak of the polynomial Wigner-Ville distribution is known to be a consistent estimator of the instantaneous frequency for polynomial FM signals. We present an algorithm for the design of an optimal time-varying window length for this estimator when noisy non-linear, not necessarily polynomial, FM signals are considered. The results obtained show that the estimator is accurate and outperforms any fixed window time-frequency distribution based estimator.
Exploiting Multiplicity to Teach Reliability and Maintainability in a Capstone Project
Authors: Janet Burge
Venue: Proceedings of the 20th Conference on Software Engineering Education & Training (2007)

Many, if not most, Computer Science programs contain some form of capstone, or senior, project as a key requirement in receiving a bachelor's degree in Computer Science or Software Engineering. One decision that needs to be made is if all the students should be developing versions of the same project or if each project should be different. In this paper we describe how having multiple teams working on the same project can enrich the capstone experience by supporting reflection on the impact the quality of their code and documentation has on the reliability and maintainability of the final product.
RPB in Software Testing
Authors: Wei Hoo Chong
Venue: Proceedings of the International Multi-Conference on Computing in the Global Information Technology (2007)

Software testing is one of the crucial activities in the system development life cycle. The purpose of testing can be quality assurance, verification and validation, or reliability estimation. In Motorola®, Automation Testing is a methodology uses by GSG-iSGT (Global Software Group - iDEN^TM Subcriber Group Testing) to increase the testing volume, productivity and reduce test cycle-time in cell phone software testing. In addition, automated stress testing can make the products become more robust before release to the market. In this paper, we will discuss one of the automation stress testing tools that iSGT use, which is RPB (Record and PlayBack). RPB is a platform specific desktop rapid test-case creation tool. This tool is able to capture all the information on the phone in order to have highest accurately in testing. Furthermore, RPB allows user to do testing at anytime, anywhere provided there is an Internet connection. Besides, we will discuss the value that automation has bought to iDEN^TM phone testing together with the metrics. We will also look into the advantages of the proposed system and some discussion of the future work.

Distant targets identification as an on-line dynamic vehicle routing problem using an active-zooming camera
Authors: A. Del Bimbo, F. Pernici
Venue: Proceedings of the 14th International Conference on Computer Communications and Networks (2005)

This paper considers the problem of modeling an active observer to plan a sequence of decisions regarding what target to look at, through a foveal-sensing action. The gathered images by the active observer provides meaningful identification imagery of distant targets which are not recognizable in a wide angle view. We propose a framework in which a pan/tilt/zoom (PTZ) camera schedules saccades in order to acquire high resolution images of as many moving targets as possible before they leave the scene. We cast the whole problem as a particular kind of dynamic discrete optimization, specially as a novel on-line dynamic vehicle routing problem (DVRP) with deadlines. We show that using an optimal choice for the sensing order of targets the total time spent in visiting the targets by the active camera can be significantly reduced. To show the effectiveness of our approach we apply congestion analysis to a dual camera system in a master-slave configuration. We report that our framework gives good results in monitoring wide areas with little extra costs with respect to approaches using a large number of cameras.
