Pupils' attitudes to technology: a review of studies which have a bearing on the attitudes which freshmen bring with them to engineering
Authors: J. Heywood
Venue: Proceedings of the 28th Annual Frontiers in Education - Volume 01 (1998)

Besterfield-Sacre, Atman and Shuman (1997) described how studies of freshman attitudes at the beginning of and during the freshman engineering program differ as a function of the student's gender and educational experiences and related this data to retention. Valuable data was found for assessing college programs. That research has been extended to other institutions and will provide useful comparative data. Interest in this issue is not confined to the United States and many studies have been conducted in other countries to elicit the attitudes of school students of all ages towards engineering and technology. The purpose of this paper is to draw attention to this work. In particular, attention is drawn to the international studies of the PATT (Pupils' Attitudes to Technology) project in the Netherlands and the outcomes of an adaptation of the PATT project in the United States. Some studies related to cognitive style and personality are briefly considered. The data from these studies suggest that engineering and school technology educators engaged in attitudinal and personality research have much to learn from each other, and would benefit from collaborative investigations. There is a need for a synthesis of the studies already undertaken so that engineering educators may evaluate the help they can bring to making the curriculum and teaching more effective.

A Protocol to Support Multi-domain Auditing of Internet-based Transport Services
Authors: Frank Eyermann, Burkhard Stiller
Venue: Proceedings of the Second International Conference on Internet Monitoring and Protection (2007)

Auditing of Service Level Agreements (SLA) defines the process of monitoring whether a service provider delivers agreed upon service levels or not. While frameworks exist to monitor application-level SLAs, the end-to-end monitoring of IPcarrying SLAs, especially in a multi-domain environment like the Internet, is still an open issue. This work analyzes methodologies how IP-carrying SLA parameters could be efficiently measured and develops a protocol, which supports this process and minimizes overhead.
Building for Users not for Experts: Designing a Visualization of the Literature Domain
Authors: Sarah Faisal, Paul Cairns, Ann Blandford
Venue: Proceedings of the 11th International Conference Information Visualization (2007)

As researchers we are constantly working with academic literature. Literature data is growing exponentially. Interacting with this huge amount of information has been a challenge for the field of HCI for years. The goal is to assist users in making sense of this information by producing usable designs. Information Visualization (InfoVis) augments users' cognition when interacting with complex data structures. Although the use of InfoVis as a tool for representing literature data is not new, we have found that most of the existing Literature Knowledge Domain Visualizations (LKDViz) target specialists known as domain analysts who study publication patterns. Our goal is to design a LKDViz tool for academic users. Due to the diversity of academic literature users we captured their experiences and used it as the main source for our design. Interestingly, this method generated design criteria that have not been applied in most of the academic literature visualizations.
Six year study of pre-engineering program at Hampton University
Authors: M. Rachedine
Venue: Proceedings of the 26th Annual Frontiers in Education - Volume 01 (1996)

In this paper a preliminary study of the impact of a pre-engineering program at Hampton University is presented. Data collected over a period of six years show that a large number of the electrical engineering students who go through the program are from this group. Data also shows that some of the students who went through the pre-engineering program graduated at the top of their class.

The computer facilities and programs developed are discussed. The results of student surveys and the teaching staff's observations, are used to evaluate the usefulness of the different tools and determine their advantages and disadvantages.
Medical application of Artificial Immune Recognition System (AIRS): Diagnosis of atherosclerosis from carotid artery Doppler signals
Authors: Fatma Latifolu, Halife Kodaz, Sadık Kara, Salih Güneş
Venue: Computers in Biology and Medicine (2007)

This study was conducted to distinguish between atherosclerosis and healthy subjects. Hence, we have employed the maximum envelope of the carotid artery Doppler sonograms derived from Fast Fourier Transformation-Welch method and Artificial Immune Recognition System (AIRS). The fuzzy appearance of the carotid artery Doppler signals makes physicians suspicious about the existence of diseases and sometimes causes false diagnosis. Our technique gets around this problem using AIRS to decide and assist the physician to make the final judgment in confidence. AIRS has reached 99.29% classification accuracy using 10-fold cross validation. Results show that the proposed method classified Doppler signals successfully.
Design for dependability in emerging technologies
Authors: Lucian Prodan, Mihai Udrescu, Oana Boncalo, Mircea Vladutiu
Venue: ACM Journal on Emerging Technologies in Computing Systems (JETC) (2007)

As current microelectronics will reach their physical limits within the foreseeable future, emerging technologies may offer a solution for maintaining the trends to increase computing performance. Biologically-inspired and quantum computing represent two emerging technology vectors for novel computing architectures within nanoelectronics. However, potential benefits will come at the cost of increased device sensitivity to the surrounding environment. This article provides a dependability perspective over these technologies from a designer's standpoint. Maintaining or increasing the dependability of unconventional computational processes is discussed in two different contexts, a bio-inspired computing architecture (the Embryonics project) and a quantum computational architecture (the QUERIST project).
Assessment strategies: feedback is too late!
Authors: S. A. Mandayam
Venue: Proceedings of the Frontiers in Education Conference, 2001. on 31st Annual - Volume 01 (2001)

The newly started Electrical and Computer Engineering program at Rowan University, USA, was visited by ABET's EAC for the first time in October 2000. As the authors prepared for their program evaluation under EC 2000, they explored novel mechanisms for assessing their curricular outcomes and "closing the loop" in an effort to develop ongoing methods for continuous program improvement. They were motivated by a strong desire to make the assessment process minimally intrusive, yet maximally effective. They have developed an assessment instrument called an X-File and a unique course called "Clinic Consultant"-both these mechanisms are closely related to each other. This paper describes their implementation efforts.
Minimum component eigen-vector based classification technique with application to TM images
Authors: Guohui He
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1999. on 1999 IEEE International Conference - Volume 06 (1999)

In this paper, we propose a new classification technique based on the minimum component analysis (MCA) instead of the traditional principal components analysis (PCA). Most existing classification techniques based on PCA like to represent a class by its principal component. However, the principal component is not always the best choice since it has a high possibility for a class to overlap with other classes in the principal component direction. The new minimum component eigen-vector based classification technique overcomes this disadvantage by representing a class with its minimum component. In addition, a minimum likelihood decision rule is employed instead of maximum likelihood decision rule. Good performance of our technique is verified by experimental results on Kennedy Space Center (KSC) TM images.
Minitack Introduction: Designing Collaboration Processes and Systems
Authors: Gert-Jan de Vreede, Robert O. Briggs
Venue: Proceedings of the 40th Annual Hawaii International Conference on System Sciences (2007)

Research shows that, under certain circumstances, groups using collaboration technologies can be far more productive than groups using other means to accomplish their tasks. Furthermore, collaboration appears to be a success critical skill in the new dynamic and innovative knowledge economy. However, experience in the field suggests that organizations do not tend to become self-sustaining in the use of collaboration support until they incorporate it into their daily work practices, in support of mission critical tasks that are guided over and over again by practitioners themselves, rather than facilitated by an outsider facilitator. The challenge for researchers and practitioners alike is to design sustainable processes and systems within and between organizations that allow people to collaborate successfully. The challenge has many dimensions, including a technical, a behavioral, an economical, and a political.
Creating a configurable compiler driver for system V release 4
Authors: John F. Dooley, Vince Guarna
Venue: Proceedings of the USENIX Applications Development Symposium Proceedings on USENIX Applications Development Symposium Proceedings (1994)

This paper discusses the design and application of the configurable C compiler driver component of System V Release 4. The configurable compiler driver is a table-driven cc command that allows users to define include file, library, and tool paths as well as command line option translations and defaults. The configurable driver presents several advantages over more traditional compiler drivers. The resulting compilation system allows many compilers with differing command line interfaces to be used in large system builds with no makefile changes. It allows the user to easily switch among several different C compilers, while presenting the user with a single command line interface. By allowing changes to compiler component paths, it makes the development of cross-compilers easier. Finally, it allows easy user configuration for the inclusion of default options. We discuss the motivation for the project, the architectural design, and applications of the driver, including experiences with using the driver for System V Release 4 system builds.
The role of expectations in the determination of educational outcomes
Authors: J. R. Mountain
Venue: Proceedings of the 30th Annual Frontiers in Education - Volume 02 (2000)

Educational outcomes assessment is becoming an important focus of education, particularly under ABET 2000 criteria for engineering education. Grades may be used to indicate the level of student competence, but are not necessarily motivators to improve the competency level. This paper presents data substantiating the adage that students will rise to the level of expectations. An analysis of graded work from a pool of approximately 750 engineering graphics students indicates that students in laboratory sections taught by teaching assistants who established higher grading standards performed at a higher level on standardized exams. In sharp contrast, students in laboratory sections with relatively lower expectations for performance displayed significantly less mastery of the course material. The maintenance of high expectations across multi-section courses is a difficult task, particularly when graduate teaching assistants assume a significant role in the day-to-day assessment of student work. A method for periodic course oversight and management by the coordinating faculty member is presented.
Visualizing Dual-Modality Rendered Volumes Using a Dual-Lookup Table Transfer Function
Authors: Jinman Kim, Stefan Eberl, Dagan Feng
Venue: Computing in Science and Engineering (2007)

In positron emission tomography/computed tomography (PET/CT) volume rendering, volume images are associated with individual lookup tables, which users must manipulate independently of the resultant volumes being fused. An intuitive, efficient dual-lookup table transfer function can improve the visualization of fused PET/CT renderings.
Maximally Fault Tolerant Directed Network Graph with Sublogarithmic Diameter for Arbitrary Number of Nodes
Authors: Pradip K. Srimani
Venue: Proceedings of the 1993 International Conference on Parallel Processing - Volume 03 (1993)

An efficient fault tolerant communication network is an integral part of designing today's parallel processing systems. In this paper we propose a new family of almost regular directed network graphs based on permutation of groups of elements for an arbitrary number of nodes. The graph is shown to have sublogarithmic diameter and almost linear number of edges and is proved to be maximally fault tolerant.
System-on-chip research leads to hardware/software co-design degree
Authors: D. J. Dent
Venue: Proceedings of the 30th Annual Frontiers in Education - Volume 02 (2000)

A case study of multi-chip module design, implementation and evaluation has been undertaken by the author at Matra Marconi Space as part of an on-going research programme into large electronic designs. Multi-chip modules offer an intermediate step towards system-on-chip. The intention of Matra Marconi Space is to use unprecedented levels of electronic integration in the next generation of communications satellites to provide the maximum number of channels thereby giving maximum revenue to the satellite operators. This case study has already had an impact on the curriculum of the degree courses at the University of Luton. Consequently, hardware description languages have been integrated into the electronics degrees for many years now and all students have extensive use of current, industry standard electronic design automation tools. The theme of all of the electronics courses at Luton is "Design, Simulate, Build and Evaluate ". Students educational experience has immediate relevance in industry which has resulted in the student's obtaining exceptionally good careers when they graduate. This case study laid the foundation of the system-on-chip research at the University of Luton that has resulted in the hardware/software co-design masters programme.

DNA and quantum theory
Authors: Mehdi Mirzaee, Milad Falahat chian
Venue: Proceedings of the First International Conference on Quantum, Nano, and Micro Technologies (2007)

Molecules are the basis of life. They can consider as a quantum system. So it is necessary to enter quantum mechanic in biological discussion. In this paper we consider the DNA molecules as a quantum system. We discussed about the relation between the heredity, biology and DNA and quantum systems. We also find a relation between the quantum information and some bio-process such as cell division, heredity, cloning. Finally we conclude that in cell division, DNA-replication and cloning all information in DNA are different.
On the Emergence of an Application-Oriented Network Architecture
Authors: Hadi Bannazadeh, Alberto Leon-Garcia
Venue: Proceedings of the IEEE International Conference on Service-Oriented Computing and Applications (2007)

There is much debate today on what should be the architecture of the next generation of networks. In this paper, we address this question from the perspective of applications. We examine current and emerging applications to identify the factors that lead to a successful deployment. In addition to new computing models, we also examine trends in the mainstream information technology and telecom service provider industry, namely, Service Oriented Architecture and IP Multimedia Subsystem. We identify requirements of, and then present some views on what constitutes the future application-oriented networks architecture, and finally we propose a new model for future application-oriented networks and we discuss the research challenges.
Statistical modeling and threshold selection of wavelet coefficients in lossy image coder
Authors: A. Przelaskowski
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 2000. on IEEE International Conference - Volume 04 (2000)

An algorithm for using wavelet domain data quantization to improve the compression efficiency is presented. A conditional probability model of adjacent (in scale-spatial sense) magnitudes was applied as a better approximation of the wavelet coefficient dependencies than the marginal data distributions. This model was utilised in the threshold data selection and is proposed as a more effective uniform quantization modification than increasing the dead-zone. The same conditional model was used in quantization and encoding of the quantized magnitudes. Additionally, to fit the adaptive threshold value to local image features, estimation of significance expectation was included in the thresholding procedure. As a result, a more effective low-cost quantization scheme was constructed. It allows a significantly increase in image compression efficiency. An experimental rate-distortion curve shows the same distortion for decreased bit rates even up to 20% in comparison to standard uniform quantization.
Generating Code from Scenario and State Based Models to Address Crosscutting Concerns
Authors: Mark Mahoney, Tzilla Elrad
Venue: Proceedings of the 29th International Conference on Software Engineering Workshops (2007)

Core application concerns are often modeled using either scenarios or state machines. Crosscutting concerns can also be modeled using either scenarios or state machines. Both scenario and state machine models can be used to generate code. When core and crosscutting concern models are the same type it is relatively straightforward to weave them together and generate code. However, when they are of dissimilar types a new approach must be taken. This paper describes how a core concern modeled as a scenario can be used with a crosscutting concern modeled with a state machine (and vice versa) to generate code.
IP multimedia subsystem converged call control services: Research Articles
Authors: Sheng Chen, Xiangyang Li, Yigang Cai
Venue: Bell Labs Technical Journal (2007)

With the IP Multimedia Subsystem (IMS) converging different access technologies in common multimedia packet core networks, Alcatel-Lucent developed an innovative standalone IMS converged charging call control service that allows the convergence of online&#x002F;offline charging for the bearer layer, IMS subsystem layer, and service layer, with call control over different networks. The service provides real-time call&#x002F;session control during the life cycle of the call&#x002F;session for voice, data, and multimedia services, such as screening, advanced routing, third-party access, and calling card service. The converged service can interwork with different media resource functions to support IMS and legacy interactive voice response (IVR) and notification services. The converged service can interwork with the online charging system (OCS) to support session- and event-based online charging capabilities, with a charging data function (CDF) and a billing system to support real-time offline charging capabilities. &copy; 2007 Alcatel-Lucent.

Authors: Dzmitry Tsetserukou, Riichiro Tadakuma, Hiroyuki Kajimoto, Naoki Kawakami
Venue: Proceedings of the Second Joint EuroHaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (2007)

In this paper, we concentrate on the design of a new whole-sensitive robot arm enabling torque measurement in each joint by means of developed optical torque sensors. When the contact of arm with an object occurs, local impedance algorithm provides active compliance of corresponding robot arm joint. Thus, the whole structure of the manipulator can safely interact with unstructured environment. The detailed design procedure of the 4-DOF robot arm and optical torque sensors is described in the paper. The gravity compensation algorithm was elaborated and verified by implementation of the local impedance control of a simple two-link arm manipulator.
An alternating explicit-implicit domain decomposition method for the parallel solution of parabolic equations
Authors: Yu Zhuang
Venue: Journal of Computational and Applied Mathematics (2007)

Explicit-implicit domain decomposition (EIDD) is a class of globally non-iterative, non-overlapping domain decomposition methods for the numerical solution of parabolic problems on parallel computers, which are highly efficient both computationally and communicationally for each time step. In this paper an alternating EIDD method is proposed which is algorithmically simple, efficient for each time step, highly parallel, and satisfies a stability condition that imposes no additional restriction to the time step restriction imposed by the consistency condition, which guarantees a convergence of order O(@Dth^-^1N"B/N)+O(h^2) in an H^1-type norm, where N"B and N, respectively, denote the number of gridpoints on the interface boundaries B and the number of gridpoints on the entire discrete domain.
Web Mash-ups and Patchwork Prototyping: User-driven technological innovation with Web 2.0 and Open Source Software
Authors: Ingbert R. Floyd, M. Cameron Jones, Dinesh Rathi, Michael B. Twidale
Venue: Proceedings of the 40th Annual Hawaii International Conference on System Sciences (2007)

The recent emergence of web mash-ups and open source software is driving the development of new practices in software and systems development. In this paper we explore novel practices of user-driven innovation through an examination of several case studies which illustrate how users and developers are exploiting the proliferation of open APIs and open source systems. Developers can rapidly create proofs of concept that are robust enough for actual use by combining preexisting software components. The underlying programming processes involved make use of tried-and-true software development techniques, and may not appear innovative at first. However, the application of these practices and techniques to problem solving by non-programmers shows a high degree of creative innovation, giving rise to new ways of thinking about technology design and production.
Recent improvements on perceptual processing using DAF wavelets
Authors: Z. Shi
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 2000. on IEEE International Conference - Volume 01 (2000)

New wavelet techniques are designed to improve the perceptual quality of images/signal, enhance and detect the detail features in the region of interest (ROI). Distributed approximating functionals (DAFs) are used to construct a new class of smooth wavelets, which enable better signal processing performance. This paper is focused on improvements in DAF wavelet signal processing. The combined perceptual techniques (such as regularization, visual group normalization and contrast nonlinear enhancement) produce natural high-quality images based on the human vision system. The underlying technologies significantly facilitate the creation of generic signal processing and computer-aided diagnostic (CAD) systems.
