Authors: J. G. Harris, B. Black
Venue: Proceedings of the Frontiers in Education Conference on 1995. Proceedings., 1995 vol 1. - Volume 01 (1995)

Six computer assisted instruction modules are available on the Internet that provide tutorials and demonstrations for nonlinear circuit analysis and design. These modules introduce the student in a sequence to the concept of a nonlinear two terminal device (one port) and its analysis and of a nonlinear three terminal device (two port) and its analysis. In addition, through interactive, graphics driven animation, the user can be provided with experience in the design of circuits with these nonlinear devices. The specific devices presented to illustrate these concepts are the pn diode and the bipolar junction transistor; there are three modules available for each. These modules are available on the Internet, either by anonymous FTP or through the auspices of NEEDS, the National Engineering Education Delivery System, being developed by the NSF SYNTHESIS Engineering Education Coalition.

An Integrated Built-In Test and Repair Approach for Memories with 2D Redundancy
Authors: Philipp Ohler, Sybille Hellebrand, Hans-Joachim Wunderlich
Venue: Proceedings of the 12th IEEE European Test Symposium (2007)

An efficient on-chip infrastructure for memory test and repair is crucial to enhance yield and availability of SoCs. Therefore embedded memories are commonly equipped with spare rows and columns (2D redundancy). To avoid the storage of large failure bitmaps needed by classical algorithms for offline repair analysis, existing heuristics for built-in repair analysis (BIRA) either follow very simple search strategies or restrict the search to smaller local bitmaps. Exact BIRA algorithms work with sub analyzers for each possible repair combination. While a parallel implementation suffers from a high hardware overhead, a serial implementation leads to high test times. The integrated built-in test and repair approach proposed in this paper interleaves test and repair analysis and supports an exact solution without failure bitmap. The basic search procedure is combined with an efficient technique to continuously reduce the problem complexity and keep the test and analysis time low.
Detection of Bronchopulmonary Segments on High-Resolution CT--Preliminary Results
Authors: Sata Busayarat, Tatjana Zrimec
Venue: Proceedings of the Twentieth IEEE International Symposium on Computer-Based Medical Systems (2007)

Bronchopulmonary segments are subdivisions of lung lobes and provide detailed description of lung anatomy. They are used in surgical resection planning and airway disease quantification. In this paper, we present a method for determining lung segments in volumetric high-resolution CT (HRCT) using segmental bronchi. The bronchial tree is automatically segmented and manually corrected to ensure optimum accuracy. The bronchopulmonary segments are determined by a 3D volume growing with a novel surface smoothing algorithm. Using the detected bronchoplumonary segments of three normal subjects, we measure the inter-patient variation of position of the segments in three subjects.

Venue: Proceedings of the Twentieth IEEE International Symposium on Computer-Based Medical Systems (2007)

In the Bulgarian health care system patients are transferred between different health care units within the health care facility, and occasionally between units that are far apart, depending on the stage of the patient's treatment progress. Determining patient resource consumption prior to utilization is vital for the management and planning of health care resources. In this paper we propose a generalized net model of patient flows that can be used to evaluate the current design (or alternative designs) in order to improve the management of the diagnostic consultative centres.
A haptic/acoustic application to allow blind the access to spatial information
Authors: F. De Felice, F. Renna, G. Attolico, A. Distante
Venue: Proceedings of the Second Joint EuroHaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (2007)

This paper describes a multi-modal application, based on haptic/acoustic interaction, to allow visually impaired people to access media with high spatial information content, extending the visual and auditoryverbal data with the tactile sensory channel. Haptic interfaces are exploited to enable the use of touch on 3D virtual objects which have a larger and greater flexibility with respect to physical artefacts. The system allows to interact with haptic/acoustic active objects and to select the information that must be shown on the basis of the user requirements. Two different tests, involving the exploration of indoor environment and of complex geographical areas, are presented. Several experiments, with users with different stories and different level of visual disability, have been done. They showed that the haptic/acoustic interaction and the modularity in the information representation help blind people to cope with the serious and challenging task of managing spatial data
LED-Glove Based Interactions in Multi-Modal Displays for Teleconferencing
Authors: Jun Park, Yeo-Lip Yoon
Venue: Proceedings of the 16th International Conference on Artificial Reality and Telexistence--Workshops (2006)

An LED-glove based interaction system is introduced in this paper to provide desktop-free interface for teleconferencing. Using proposed interaction technology, users may collaborate with other remote users in multi-modal display environments. Private displays (LCD or head mounted displays) are used to organize data or refer to classified information, and shared display (projection display) is used to present and share information with other users. Interaction is composed of two modes. In mouse replacement mode, the glove may be used as a traditional mouse. Postures were used for mouse's click and double-click of left/right buttons. In command mode, gestures were used for frequently used commands such as switching displays, moving information inter-display, fetching data from other displays, etc. Gestures were recognized with high success rate (above 94%) using Hidden Markov Model. In order to solve gesture-spotting problem, we used switches to turn on LEDs during gesture performance. Preliminary studies show that the proposed system is easy to use, and provides most useful interface for multi-modal display teleconferencing.
Multi-path maxmin flow control and routing
Authors: Wei K. Tsai
Venue:  (2006)

The maxmin fair bandwidth allocation has been proposed as a flow/congestion control mechanism for managing the data traffic in connection-oriented networks. In this project, we solve the combined problem of routing and flow control for each connection such that every source rate will be maximized and fairness will be maintained. We propose two novel algorithms to multi-level multi-path maxmin problems. First, we apply Lagrange multiplier approach, which is a primal-dual method, to solve maxmin level separation. Second, we devise a fast convergence algorithm based on the least square approach to reduce computation complexity and to extend Constraint Precedence Graph in multi-path networks. We prove that the least square result obtained by our method converges to the optimal solution which is multi-path multi-level maxmin. In addition, we propose two approaches to solve multi-path maxmin routing problems. First, we contribute a multi-path maxmin routing algorithm based on dual variables. We use Lagrange multiplier method to solve multi-level multi-path maxmin and obtain the dual variables. Using the dual variables as the link weights to solve the routing problem. Second, we extend the concept of advertised rate from single-path to multi-path and contribute a multi-path maxmin routing algorithm based on that. We prove that using this new advertised rate algorithm will converge to multi-path maxmin solution.
A new risk model based on policy entrance process and its weak convergence properties: Research Articles
Authors: Zehui Li, Xinbing Kong
Venue: Applied Stochastic Models in Business and Industry (2007)

In this paper, we construct a new risk model based on the policy entrance process. The model is concerned with n kinds of independent policies, and each policy is allowed to claim more than once before it expires. As each kind of policy is issued according to a non-homogeneous Poisson process, the long run behaviour of the new risk process is investigated. When the tail of the claim size distribution is regularly varying, the standardized risk process is proved to converge to a stable law. When each kind of policy is issued according to a homogeneous Poisson process, we also give a diffusion approximation of the new risk process. Copyright &copy; 2007 John Wiley & Sons, Ltd.
Reconciling Agility and Discipline in COTS Selection Processes
Authors: Fredy Navarrete, Pere Botella, Xavier Franch
Venue: Proceedings of the Sixth International IEEE Conference on Commercial-off-the-Shelf (COTS)-Based Software Systems (2007)

Currently, information systems are mainly built by integrating or customizing Commercial Off-The-Shelf (COTS) components acquired or licensed from the marketplace. The processes necessary to steer a suitable acquisition are different from traditional software development processes. Among them, we are interested in the process of selection of COTS components. COTS selection requires discipline to coordinate the selection team and the set of new activities that are necessary to support a successful selection. The Capability Maturity Model (CMM) contains important guidelines for process improvement, and specifies "what" we must have into account to achieve the disciplined processes (among others things). On the other hand, agile methods are playing nowadays an important role in software engineering practices, because they are specifying "how" the software practices must be addressed to attain agility and improvement in the software processes. The contribution of this work is to propose a framework to reconcile agile and discipline-based approaches in the COTS selection domain, by including agile practices into the 5 levels of CMMI for COTS acquisition.
Looking Ahead: A Contributor's Perspective on the Next-Stage Advances in Competitive Strategy, Economics and Information Systems Research
Authors: Robert J. Kauffman
Venue: Proceedings of the 40th Annual Hawaii International Conference on System Sciences (2007)

I discuss several directions for research in the area of competitive strategy, economics and information systems. My remarks center on the potential for advances in the following areas: (1) the macroeconomic impacts of technology, and opportunities to explore the issues, theories and methods of aggregate analysis relative to IT industry agglomeration, technology diffusion and firm strategies; (2) theoretical and methodological knowledge for the exploration of technology adoption and business value, by leveraging the tensions from game-theoretic equilibrium analysis outcomes and technological change-led transformations; (3) further developing our valuation, risk management and services science approaches for business processes involving organizational systems, interorganization relationships, and market connections. The latter applies in such contexts as e-commerce services pricing, utility computing and Web services, and managerial approaches to IT project portfolio management. My expectation there is much to be learned in the next twenty years about that managerial decision-making in a world of business operations that involve mobility, and ubiquitous data and support, and technologies that will transform production, consumption, market value, social welfare and the way our business economy works.
Imaging as an educational tool in natural resources engineering
Authors: J. C. Hayes, A. R. Overton
Venue: Proceedings of the Frontiers in Education Conference, on 1995. Proceedings., 1995 - Volume 02 (1995)

Application of engineering to design "real world" situations is the goal of most engineering design courses. Unfortunately, achieving this is easier said than done, particularly for situations including land use and engineering structures. Computer imaging provides one alternative that has potential for bridging the gap between an instructor's view of a situation and that of the student. Changing conditions are often used in "what if ...?" problems related to runoff and erosion. For example, runoff and erosion estimates from a forested condition are compared with results from a developed condition. A common difficulty in explanation and analysis of such problems is difficulty in describing the land use. Either the instructor provides a description that is almost word for word like one shown in a textbook's table or the students have widely varying perceptions as to what the situation is. In either case, students are unable to demonstrate engineering judgement. Thus, little applicability to real world problems exists. The paper describes application of computer imaging to improve engineering design associated with soil and water engineering. Specific objectives include the following: investigate feasibility of available imaging methods to improve educational delivery; evaluate use of imaging for applications in soil and water engineering; demonstrate applications that relate engineering judgement to real world problems.
Research Collaborations between Academia and Industry
Authors: Dieter Rombach, Reinhold Achatz
Venue: 2007 Future of Software Engineering (2007)

The rapid and complex research and innovation processes require high-tech companies to optimize their technology transfer processes. It is clearly not sufficient to solely rely on internal R&D; strategic cooperations with external research centers of excellence are needed in order to compete in the global innovation market. Candidates for such strategic cooperations are universities, research institutions, and technology focused consulting companies. Key challenge is the effective integration of external competences into the company-internal innovation processes. In this paper we present a survey of the state-of-the-art in technology transfer, high-light promising success cases for the future, and derive success criteria for successful technology transfer in a global world. The cooperation between Siemens and Fraunhofer IESE is presented as a concrete example.
Classroom learning techniques
Authors: R. J. Hofinger
Venue: Proceedings of the 26th Annual Frontiers in Education - Volume 01 (1996)

One of the basic skills in learning in college is to be able to listen properly. Listening is the first step in learning. Bad listening habits are as easy to cultivate as good ones. In this paper, I present ten bad listening habits to be avoided. Just because we hear something, it doesn't mean we are listening. We don't have to hear to learn, but we do have to listen to learn. We don't have to learn to hear, but we do have to learn to listen. Listening involves concentration, and concentration involves holding a central issue or problem in mind and having ideas that are related to the issue. Why take notes? Because listening and note-taking are inseparable partners. Any experienced reporter will confirm this. The only way to take notes is to listen, and the only way to listen is to take notes. Listen without taking notes and you'll quickly forget. The objective in taking notes in class is to capture the instructor's ideas and information in the order in which they are presented; to be able to retrieve those ideas and information months and possibly years from now. I present a technique for note-taking that I feel is one that you should consider passing on to your students.

Authors: Rahul Vanam, Eve A. x. Eve A. Riskin, Sheila S. Hemami, Richard E. Ladner
Venue: Proceedings of the 2007 Data Compression Conference (2007)

The H.264/ACV standard provides significant improvements in performance over earlier video coding standards at the cost of increased complexity. Our challenge is to determine H.264 parameter settings that have low complexity but still offer high video quality. In this paper, we propose two fast algorithms for finding the H.264 parameter settings that take about 1% and 8%, respectively, of the number of tests required by an exhaustive search. Both the fast algorithms result in a maximum decrease in peak-signal-to-noise ratio of less than 0.71 dB for different data sets and bitrates.
Measurement-based characterization of a collection of on-line games
Authors: Chris Chambers, Wu-chang Feng, Sambit Sahu, Debanjan Saha
Venue: Proceedings of the 5th ACM SIGCOMM conference on Internet Measurement (2005)

On-line games are a rapidly growing Internet application. Because of the cost in supporting on-line games and the unpredictable load on servers, companies are moving toward sharing infrastructure for game hosting. To efficiently provision on-line games, it is important to understand game workloads and the behavior of game players. In this paper, we present a comprehensive analysis of a collection of on-line game players and game workloads using data from several sources including: a 13-month trace of an extremely busy game server containing over 2.8 million connections, a two-year trace of the aggregate game populations of over 550 on-line games, and a 4-month trace of a content-distribution network used to deliver games. The key findings from our measurement study are: (1) these gamers are an extremely difficult set of users to satisfy and unless game servers are properly set up and provisioned, gamers quickly choose to go elsewhere, (2) the popularity of these games follows a power law making games difficult to provision at launch time, (3) game workloads are predictable only over short-term intervals, (4) there are significant challenges in hosting games on shared infrastructure due to temporal and geographic synchronization across different games and other interactive applications, and (5) game software updates are a significent burden on game hosting that must be planned for. Our results have implications for both game publishers as well as infrastructure providers.
Efficient and effective algorithms for controllable fluid simulation and mesh deformation
Authors: Yizhou Yu
Venue:  (2006)

During the past decade, due to rapidly growing computational power, complicated numerical algorithms have become popular in graphics community which greatly improved the quality of graphics imagery. On the other hand, to produce high-quality visual effects, the size of the data being processed has also increased drastically at the same time. Thus efficient algorithms are desired in many applications. This dissertation focuses on problems in controlling fluid simulations and mesh deformations. It has potential applications in film and game industries. The first part of this dissertation includes efficient algorithms for controlling the motion of gas and liquid. The efficiency is achieved by using feedback forces to drive the fluid toward the target. Without expensive optimization procedures, the control algorithms produce desired and natural results that only incur an additional computational cost linear to the size of the problem. Controlling the motion of lightweight natural objects in a gaseous medium is also studied, using data-driven synthesis based on stylistic motion planning and nonlinear optimization based on smoothed particle hydrodynamics. In addition, we also introduce a simple algorithm to perform plausible fluid simulation over triangle meshes. In the second part, we focus on mesh deformation algorithms. To avoid expensive numerical solvers using factorization techniques, a fast multigrid algorithm is developed. The key observation here is that reasonable results can be achieved using more accurate restriction/prolongation operators combined with a simple and effective graph coarsening strategy. The algorithm has very good performance and scalability.
Moats and Drawbridges: An Isolation Primitive for Reconfigurable Hardware Based Systems
Authors: Ted Huffmire, Brett Brotherton, Gang Wang, Timothy Sherwood, Ryan Kastner, Timothy Levin, Thuy Nguyen, Cynthia Irvine
Venue: Proceedings of the 2007 IEEE Symposium on Security and Privacy (2007)

Blurring the line between software and hardware, reconfigurable devices strike a balance between the raw high speed of custom silicon and the post-fabrication flexibility of general-purpose processors. While this flexibility is a boon for embedded system developers, who can now rapidly prototype and deploy solutions with performance approaching custom designs, this results in a system development methodology where functionality is stitched together from a variety of "soft IP cores," often provided by multiple vendors with different levels of trust. Unlike traditional software where resources are managed by an operating system, soft IP cores necessarily have very fine grain control over the underlying hardware. To address this problem, the embedded systems community requires novel security primitives which address the realities of modern reconfigurable hardware. We propose an isolation primitive, moats and drawbridges, that are built around four design properties: logical isolation, interconnect traceability, secure reconfigurable broadcast, and configuration scrubbing. Each of these is a fundamental operation with easily understood formal properties, yet maps cleanly and efficiently to a wide variety of reconfigurable devices. We carefully quantify the required overheads on real FPGAs and demonstrate the utility of our methods by applying them to the practical problem of memory protection.

Improving speech recognition performance by using multi-model approaches
Authors: Ji Ming
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1999. on 1999 IEEE International Conference - Volume 01 (1999)

Most current speech recognition systems are built upon a single type of model, e.g. an HMM or certain type of segment based model, and furthermore typically employs only one type of acoustic feature e.g. MFCCs and their variants. This entails that the system may not be robust should the modeling assumptions be violated. Recent research efforts have investigated the use of multi-scale/multi-band acoustic features for robust speech recognition. This paper described a multi-model approach as an alternative and complement to the multi-feature approaches. The multi-model approach seeks a combination of different types of acoustic models, thereby integrating the capabilities of each individual model for capturing discriminative information. An example system built upon the combination of the standard HMM technique with a segment-based modeling technique was implemented. Experiments for both isolated-word and continuous speech recognition have shown improved performances over each of the individual models considered in isolation.
