The computer society of the Institute for Electrical and Electronic Engineers (IEEE-CS) and the Association for Computing Machinery (ACM) established the joint task force on Computing Curricula 2001 (CC2001) to undertake a major review of curriculum guidelines for undergraduate programs in computing. The effort was to match the latest developments of computing technologies in the past decade and last through the next decade. The "Computing Curriculum 1991" and other previous efforts of the IEEE-CS and ACM did not distinguish computer science from computer engineering programs. The IEEE-CS and ACM established the computing curriculum - computer engineering (CCCE) task force in 2001 to develop a separate volume on computer engineering curricula to complement the CC2001 report. The work of the CCCE task force appears as a report available for review on the web. This report has undergone extensive review, including an NSF-sponsored workshop. By the time of this conference, the final report will have been presented to the IEEE-CS and ACM, and made available for distribution. This panel presents an overview of that report.

This presentation is a work in progress on the launching and continuing development of an educational portal for all areas of computing. The portal is the result of the National Science Foundation's initiative to develop digital content useful for educators, students, and people in industry. One content area of this initiative encompasses areas of computer science, computer engineering, software engineering, information systems, information technology, and all other areas of computing. A consortium of five institutions, each bringing a different perspective to the project, is responsible for acquiring the computing content. Historical developments in computing serve as a theme in the collection of educational resources. The presentation shows how educators can employ the NSF initiative to enhance their teaching.

This demonstration will illustrate the use of existing and proposed tools in CITIDEL for finding existing resources to integrate into a course and for developing well structured descriptions of class and laboratory activities for sharing with the computing community.

One of the problems in advancing the state of the software engineering discipline is the inadequate preparation of students entering the profession from undergraduate computing programs. This panel...

This presentation is a work in progress on the development of an educational portal for all areas of computing. This work is being developed through the digital library initiative of the National Science Foundation. The purpose of this project is to develop computing content useful for educators, students, and persons in industry. The scope of the content includes computer science, computer engineering, software engineering, information systems, information technology, and all other areas of computing. A consortium of five institutions, each bringing a different perspective to the project, is responsible for acquiring the content. The project seeks to reach out to underrepresented communities so that computing material is accessible to them. Industrial institutions play a role in this project by contributing educational and training material and having that material accessible to others. Historical developments in computing serve as a theme in the collection of educational resources.

The NSDL consists of collections of materials accessible online, as well as many tools and services intended to enhance learning. Tools and services will support students and as well as faculty. This session will provide a status report on the state of the NSDL, its content, tools, and services. The session includes specific presentations of several services included in the NSDL. Session attendees discuss current and proposed initiatives, and offer suggestions about needs of highest priority.

The past ten years have demonstrated an insurgence and explosive growth of digital libraries. This paper shows how the National Science Foundation STEM (Science, Technology, Engineering, and Mathematics) Education Digital Library (NSDL) initiative can be useful to teachers and students engaged in distance learning and education. It will also explore how the computing component of NSDL can be a vital tool for the study of computing.

Summary form only given. For the computing discipline, history seldom receives status. From a cultural standpoint history broadens one's perspective on the field and lets students and scholars explore the inner thinking of people and the events they produced. From a practical standpoint, history enables individuals and enterprises to learn from the events of the past and to improve on experiences. Both views are necessary to create an informed computing professional. Teachers often ignore history of computing when teaching their computing courses. The typical case is that educators mention some facts or important milestones usually related to hardware and the people responsible for these. The discussion then moves quickly to other topics. This is unfortunate, because we can learn much from history. History is the best teacher to assess the meaningful evolution of the computing profession. The IFIP Joint (TC3-TC9) Task Group has examined this concern and is producing a report entitled: History in the Computing Curriculum. The report addresses the need to include history in the curriculum and serves as a basis for this proposal. It also provides educators, whose formal study of computing history is minimal or nonexistent, ways in which to teach computing history in an educational environment. This paper presents the work of the IFIP Joint Task Group to a computing and engineering audience.

This panel focuses on the usefulness of accreditation in the software and design aspects of computing, including computer science, information systems, and software engineering.

A portable high-resolution sonar has been under development to provide Navy divers with acoustic imaging systems for mine reconnaissance. The first phase of development was completed in 2000 with the demonstration of a broadband, 6% sparse line array, imaging a simple target in the NUWC Acoustic Test Facility (ATF). Element locations for this array were computed based on a grid point optimization technique which minimized close-in sidelobes. The center frequency was 2 MHz with a 667 kHz bandwidth. A new sparse planar array, consisting of 121 1 mm/spl times/1 mm 2 MHz elements, has been fabricated, to provide 3-D acoustic images of underwater targets. This array was also designed using the grid point optimization technique.

Many computing people call themselves professionals without the necessary validation or credentials that other professional groups possess. Perhaps computing needs greater maturity to develop standards of best practices. Even defining the meaning of a computing profession may be difficult. The article explores perspectives on these and related issues.

The National Science Foundation has recently funded a variety of projects through its NSDL digital library initiative. One such project is the Computing and Information Technology Interactive Digital Educational Library project, also known as CITIDEL, which is part of NSDL’s Collection Track activities. CITIDEL is a consortium of five universities that includes Virginia Tech (the lead institution), Hofstra University, Penn State University, The College of New Jersey, and Villanova University. CITIDEL will establish, operate, and maintain part of the digital library that includes information systems, computer science, information science, information technology, software engineering, computer engineering, and other computing-related fields. It will manage a front-end portal to all educational activities related to computing and information technology, harvest metadata from applicable repositories, provide an integrated access and linking process to related collections, and encourage and actively support content developers to make new resources available to others. CITIDEL will also address the need to develop and disseminate quality courseware by providing a mechanism for the preservation of educational prototypes. Additionally, it will provide a single location where searches conducted by educators and students can link them educational websites.

Although accreditation is over 100 years old, the accreditation of information systems programs is a new experience for information systems professionals. This paper describes the important aspects of accreditation as a process of excellence and shows how information systems faculty members can now employ that process to improve the overall quality of their programs for the benefit of their students, their institutions, and their profession.

The need for multiple, cost-effective deployment of undersea acoustic mine-field reconnaissance and mine-hunting systems requires the development of light-weight, low-power, high- resolution sonars. These imaging sonars should be portable enough for use in a diver's hands or in a remote imaging sonar on an unmanned undersea vehicle in shallow waters. Under the support of the DARPA Sonoelectronics program, a system that can simultaneously focus many signals using multiple CCD/CMOS, programmable time-delay beamforming circuits connected to a sparsely-populated 2D acoustic array, is being developed. Using this approach, a real-time image could be formed to search for mine-like objects. To make a sparse array practical, the combination of low insertion loss and wide bandwidth performance is critical to realizing acceptable imaging performance with low illumination levels. In this system, a 20 cm diameter 2 MHz sparse array providing a 0.21 degree main beamwidth is proposed. Using this array, a real-time 2D cross-sectional scan of 128 X 128 pixels is achievable with a down-range and cross-range resolution of approximately 1 cm at a range of 3 m. In this paper, the signal-to-clutter ratios as a function of array bandwidth and sparse-array elements placement are presented. Furthermore, the performance of a CCD/CMOS subarray processor will be reported.

This wavelet based data compression algorithm addresses a growing need to handle large quantities of image data quickly and efficiently. This wavelet technique has been coded based on the assumption that small coefficients computed by the two-dimensional orthogonal wavelet transform are principally associated with image noise, and only the largest values are required to capture the information content of the respective source image. The approach has been successfully applied to one-dimensional signals in the design of signal classifiers. This particular algorithm for wavelet-based image compression has been designed and compared to the Joint Photographic Expert Group (JPEG) still picture image compression standard. Examples are shown of side scan sonar images, x rays, and laser line scan images.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.

This study explores the ability of wavelets and wavelet packets to extract information from non-stationary signals for the purpose of classification. The signals used were of two types: non-stationary signals from three marine mammals (dolphins, porpoises, and sperm whales), and quasi-stationary signals from an experimental undersea vehicle. This study also focuses on the impact of the compression ratio and the basis selection on the performance of a given classifier.

In this poster, the author provides a pictorial demonstration of the elements associated with assessment and its relationship to the newly developed requirements by accrediting bodies in various countries. Specifically, it illustrates expected attributes of program graduates and it highlights the importance of performance measures when assessing learning outcomes of a program. The poster shows forms of assessment and it provides definitions and examples of program mission, goals, and learning outcomes, performance indicators, performance measures, and the use of rubrics. The poster highlights the interaction of all these assessment characteristics.

A three‐dimensional sonar imaging system is under development for use by Navy divers for mine‐field reconnaissance and mine‐hunting systems. Divers require a small, low‐power, lightweight acoustic imaging system with high resolution for examining and disposing of underwater ordinance. Sparse array technology is investigated to develop a sonar requiring the minimal number of signal processing channels while maintaining the beamwidth and sidelobe structure required for high‐resolution imaging. Beamwidth and sidelobe structure are examined as a function of transducer element count, channel bandwith, and element location when optimized using various cost functions. Locally optimum solutions are computed for uniformly weighted sparse arrays. Cost functions evaluated for the optimization process compute average sidelobe energy, peak sidelobe energy and a weighted average sidelobe energy. Images will be formed using multiple CCD/CMOS time‐delay beamforming circuits to compute the large number of beams required to provide a real‐time high‐resolution image.

Since the issuance of the message above, the response from the SIGCSE community has been overwhelmingly positive. SIGCSE members seem delighted with the prospect that authors submitting articles to inroads will hopefully receive a new level of acceptance from the academic community. That is, their work would not be relegated to "newsletter" status, but to a new and more acceptable level of quality in a magazine.

This poster describes a progress to conclusion of the Computing Curricula 2005 (CC2005) report. It demonstrates the status of this work and highlights its salient features. These features include the scope of the computing areas of computer engineering, computer science, information systems, information technology, and software engineering. The poster illustrates the commonalities and differences of these areas and shows some of the outcome expectancies of the graduates from these programs. It also demonstrates a new addition - a "guide" - intended for distribution to high schools throughout the United States and elsewhere. Participants of the poster session would have the opportunity to comment on this guide before it goes public.

A high‐resolution, handheld imaging sonar system has been developed by Teratech Corporation for the U.S. Navy. This is a 192‐channel, dual‐frequency bistatic sonar for Navy divers performing search and survey missions for underwater explosives. The goal is to provide the most compact and energy‐efficient imaging system for the divers. The low power and small volume are a result of the development of Teratech’s Charge Domain Processing (CDP) technology. This technology has led to the development of a low‐power 64‐channel beamformer chip. As a result, only three beamformer chips are needed for the 192‐element array. Until now, implementation of small, low‐power sonar systems containing this many elements and forming enough beams to create an image was considered impossible. Test results and acoustic images obtained in Teratech’s acoustic test tank will be presented.

In 2001, the ACM and the IEEE-CS published Computing Curricula 2001 which contains curriculum recommendations for undergraduate programs in computer science. That report also called for additional discipline-specific volumes for each of computer engineering, information systems, and software engineering. In addition, it called for an Overview Volume to provide a synthesis of the various volumes. The Computing Curricula 2004 Task Force has undertaken a two-pronged strategy to fulfill the latter charge. The purpose of this session is to present an overview of the Task Force's work and to generate feedback from the SIGCSE membership to the Task Force about the direction and plans we have undertaken.

This demonstration allows conference attendees to gain experience in using the facilities of the NSF National Science Technology Engineering and Mathematics Education Digital Library (NSDL) to prepare and present College or university level classes.

A handheld high resolution sonar has been under development to provide Navy Divers with a 3‐D acoustic imaging system for mine reconnaissance. An ultra‐sparse planar array, consisting of 121 1 mm×1 mm, 2 MHz elements, was fabricated to provide 3‐D acoustic images. The array was 10 cm×10 cm. A full array at this frequency with elements at half‐wavelength spacing would consist of 16 384 elements. The first phase of testing of the planar array was completed in September 2001 with the characterization of the array in the NUWC Acoustic Test Facility (ATF). The center frequency was 2 MHz with a 667 kHz bandwidth. A system‐level technology demonstration will be conducted in July 2002 with a real‐time beamformer and near real‐time 3‐D imaging software. The demonstration phase consists of imaging simple targets at a range of 3 m in the ATF. Experimental results obtained will be reported on.

Wavelet analysis techniques were applied to side scan sonar images for the detection of minelike objects. A subwindow of sample images were scanned and compressed using a best level orthogonal wavelet basis. The compressed images were then projected onto a dictionary of target and nontarget examples in wavelet space, using the matching pursuit algorithm of Mallat and Zhang to find the most likely match. With the best level basis, however, signal representations are dependent on their location in space. Because of this, shifted versions of the target examples were included in the dictionary to improve the likelihood of a good numerical match. Shift‐invariant wavelet techniques, which provide for target translation while maintaining the same numerical descriptors, were also studied with classifier performance and computational complexity being evaluated. This allowed best bases representations to be applied in the classification algorithm. The overall detection performance was further refined by use of a ne...

Standing-wave measurements on a periodic traveling-wave array of dipoles driven with glide-symmetric excitation from a coaxial transmission line show the existence of multimode propagation in certain frequency bands. This phenomenon is explianed qualitatively in terms of coupling of symmetric and antisymmetric modes of the dipole array by the excitation from an unbalanced line. It has not been found when the dipoles are driven from a balanced two-conductor line. The avoidance of such multimode phenomena is crucial to the self-balancing property of successful log-periodic dipole arrays.

The three premises of classical stable theory of population (closure to migration, time independent age-specific birth and death rates), if staunchly upheld, would eliminate virtually every existing biological population as a subject for its use. One must concede, for example, that human population is exposed to migration, and that birth rates and death rates are not constant over time. In this light, one may erroneously conclude that stable theory, even in its classical sense, serves little or no purpose. This is far from true. It must be remembered that stable theory serves as a model for study of a given population, and not as an impeccable image of it. Viewed in this manner, the concepts and formulations of stable theory do have much to offer, both as a mathematical entity as well as an applicable tool to be used in population study.

Demography is the study of population, primarily human population, in terms of its growth and decay, its fertility and mortality, its relative mobility, and its composition, density and size. The impact on economic, political and social components of society has always been of interest to demographers. Early studies of demography as a science can be traced back to the Roman Empire, where in the year 225 A.D., the mortality schedules of Macer and Ulpian were the first published documents on the subject.
