Authors: Scott A. Morton, James R. Forsythe, Kenneth E. Wurtzler, David R. McDaniel, Russell M. Cummings, Stefan Goertz, Stefan Siegel, Kyle D. Squires
Venue: Proceedings of the HPCMP Users Group Conference (2006)

This paper documents some of the early results of a three year project to develop a computational method for accurately determining static and dynamic stability and control characteristics of fighter and transport aircraft with various weapons configurations as well as the aircraft response to pilot input. In this first year of the project computational data is gathered for a rigid F-16 with no control surface movement in forced motion that approximates flight test maneuvers and wind-tunnel testing techniques. The data is then post-processed to determine the resulting static and dynamic stability characteristics. Static and rigid body motion simulations of the Blended Wing Body bomber/transport concept are performed and compared to detailed experimental data to validate the numerical approach. The main benefits of this effort are: 1) early discovery of complex aerodynamic phenomena that are typically only present in dynamic flight maneuvers and therefore not discovered until flight test, and 2) rapid generation of an accurate aerodynamic database to support aircraft and weapon certification by reducing required flight test hours and complementing current stability and control testing.
Layout-aware gate duplication and buffer insertion
Authors: D. Bañeres, J. Cortadella, M. Kishinevsky
Venue: Proceedings of the conference on Design, automation and test in Europe (2007)

An approach for layout-aware interconnect optimization is presented. It is based on the combination of three sub-problems into the same framework: gate duplication, buffer insertion and placement. Different techniques to control the combinatorial explosion are proposed. The experimental results show tangible benefits in delay that endorse the suitability of integrating the three sub-problems in the same framework. The results also corroborate the increasing relevance of interconnect optimization in future semiconductor technologies.

Authors: K. Bommanna Raja, M. Madheswaran, K. Thyagarajah
Venue: Proceedings of the International Conference on Computing: Theory and Applications (2007)

The objective of this work is to provide a set of most significant content descriptive feature parameters to identify and classify the kidney disorders with ultrasound scan. The ultrasound images are initially pre-processed to preserve the pixels of interest prior to feature extraction. In total 28 features are extracted, the analysis of features value shows that 13 features are highly significant in discrimination. This resultant feature vector is used to train the multilayer back propagation network. The network is tested with the unknown samples. The outcome of multi- layer back propagation network is verified with medical experts and this confirms classification efficiency of 90.47%, 86.66%, and 85.71% for the classes considered respectively. The study shows that feature extraction after pre-processing followed by ANN based classification significantly enhance objective diagnosis and provides the possibility of developing computer-aided diagnosis system.
Simulation-based functional test generation for embedded processors
Authors: C. H. -P. Wen, L. C. Wang, Kwang-Ting Cheng
Venue: Proceedings of the High-Level Design Validation and Test Workshop, 2005. on Tenth IEEE International (2005)

Deterministic functional test pattern generation has been a long-standing open problem, which is an important problem to be solved for both design verification and manufacturing testing. One key to develop a practical functional test pattern generation approach is to avoid the exponential growth of the test generation complexity in terms of the growth in design size. This work proposes a functional test generation approach where simulation results are used to guide the generation of additional tests. Our methodology avoids the complexity growth issue by converting some modules in a design into simpler and more efficient models. Then, these models are used to facilitate the actual test generation process. We develop two sets of techniques to achieve these conversions. One is called Boolean learning to be applied on random logic and the other is called arithmetic learning to be applied on datapath modules. We demonstrate the effectivenesses and discuss the limitations of these techniques through experiments on benchmark circuits. We validate the overall test generation methodology based on the OpenRISC 1200 microprocessor.
Quantum t-designs: t-wise Independence in the Quantum World
Authors: Andris Ambainis, Joseph Emerson
Venue: Proceedings of the Twenty-Second Annual IEEE Conference on Computational Complexity (2007)

A t-design for quantum states is a finite set of quantum states with the property of simulating the Haar-measure on quantum states w.r.t. any test that uses at most t copies of a state. We give efficient constructions for approximate quantum t-designs for arbitrary t. We then show that an approximate 4-design provides a derandomization of the statedistinction problem considered by Sen (quant-ph/0512085), which is relevant to solving certain instances of the hidden subgroup problem.
Genetic Exchange Leading to Self-Assembling RNA Species upon Encapsulation in Artificial Protocells
Authors: Sergio-Francis M. Zenisek, Eric J. Hayden, Niles Lehman
Venue: Artificial Life (2007)

The encapsulation of information-bearing macromolecules inside protocells is a critical step in scenarios for the origins of life on the Earth as well as for the construction of artificial living systems. For these protocells to emulate life, they must be able to transmit genetic information to other cells. We have used a water-in-oil emulsion system to simulate the compartmentalization of catalytic RNA molecules. By exploiting RNA-directed recombination reactions previously developed in our laboratory, including a ribozyme self-assembly pathway, we demonstrate that it is possible for information to be exchanged among protocells. This can happen either indirectly by the passage of divalent cations through the inter-protocellular medium (oil), or by the direct interaction of two or more protocells that allows RNA molecules to be exchanged. The degree of agitation affects the ability of such exchange. The consequences of these results include the implications that prototypical living systems can transmit information among compartments, and that the environment can regulate the extent of this crosstalk.
Interpreted C++, object oriented Tcl, what next?
Authors: Dean Sheehan
Venue: Proceedings of the 3rd Annual USENIX Workshop on Tcl/Tk - Volume 3 (1995)

Tcl[1] is an interpreted high level language suitable for scripts, small scale systems, prototypes and embedding in larger applications. C++ is a powerful compiled language that provides support for object oriented programming and is suitable for building large complex systems. But what if you could move from C++ to Tcl and back again with the ease of an object reference and a dynamically bound function? This paper describes an extension to Tcl, or an extension to C++ depending on your perspective, that makes it possible to: • use object oriented programming concepts in Tcl • inherit from C++ classes (with dynamic binding of methods) in Tcl • instantiate C++ classes from Tcl • invoke methods upon C++ objects from Tcl • delete C++ objects from Tcl • pass Tcl objects to C++ for method invocation and deletion. The name of this extension (Tcl++ was rejected) is Object Tcl.
Oriented soft localized subspace classification
Authors: T. Balachander
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1999. on 1999 IEEE International Conference - Volume 02 (1999)

Subspace methods of pattern recognition form an interesting and popular classification paradigm. The earliest subspace method of classification was the class featuring information compression (CLAFIC) which associated with each class a linear subspace. Local subspace classification methodologies which have enhanced classification power by associating multiple linear subspaces with each class have also been investigated. In this paper, we introduce the oriented soft regional subspace classifier (OS-RSC). The highlights of this classifier are: (i) class specific subspaces are formed to specifically maximize the average projection of one class while minimizing that of the rival class; (ii) multiple manifolds are formed for each class increasing the classification power; and (iii) soft sharing of the training patterns again allows for consistent classification performance. It turns out that the cost function for forming class specific subspaces is maximized for a subspace of unit dimensionality. The performance of the proposed classifier is tested on real-world classification problems.
Re-purposing existing generic games and simulations for e-learning
Authors: Daniel Burgos, Colin Tattersall, Rob Koper
Venue: Computers in Human Behavior (2007)

There is a growing interest among teachers in using games as a part of their lesson plans. A standardised, interoperable approach to the sharing of such game-based lesson plans would allow teachers and educational technologists to compare and contrast Digital Game Based Learning scenarios, allowing best practices and lessons learned to emerge. Although games can be used as 'add-ons' in educational contexts, greater benefits can be attained by integrating games more fully into the educational process, i.e. by repurposing existing games to target the specific learning objectives. In this article we analyse this problem. We developed two possible solutions based on the integration and the interaction of games and learning scenarios. The first solution is based on 'pedagogical wrappers', where games are linked to e-learning flows but without interaction and communication. The second solution sees a tighter integration which supports ongoing interaction and communication between game and e-learning flow. We applied both solutions to a generic game. This game was firstly programmed in Action Script and later re-used for learning purposes and represented in IMS Learning Design. We analysed the pros and cons of each solution and identify research topics for further research.

Authors: M. Schlegel, G. Herrmann, D. Muller
Venue: Proceedings of the Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS (2003)

The paper is focussing on high abstraction level CAD modeling of MEMS using a new methodical approach called "Multi Architecture Modeling" which makes it possible to simulate models at different abstraction levels together. The paper presents the MAM method and its application to the design of the experimental prototype "vibration sensor array". This system consists of a micromechanical sensor (array of laterally moving mass-spring systems, fabricated by SCREAM technology, intended for low cost applications in wear state recognition), an environmental model for the sensor, analog and digital signal processing.
A Universal Construction for Concurrent Objects
Authors: Rachid GUERRAOUI, Michel RAYNAL
Venue: Proceedings of the The Second International Conference on Availability, Reliability and Security (2007)

A concurrent object is an object that can be concurrently accessed by several processes. A wait-free implementation of an object is such that any operation issued by a non-faulty process terminates in a finite number of its own steps, whatever the behavior of the other processes (that can be very slow or even have crashed). An object type is universal if objects of that type, together with atomic registers, allows implementing any concurrent object defined by a sequential specification. A universal construction is a wait-free algorithm, based only on atomic registers and universal objects, that, given any sequential object type T, provides the processes with a wait-free concurrent object of the type T. In a famous paper (titled "Wait-free synchronization") Herlihy has shown that consensus objects are universal, and has presented a consensus-based universal construction.

Authors: Tomoyuki Ishida, Go Chiba, Akihiro Miyakawa, Yoshitaka Shibata
Venue: Proceedings of the 21st International Conference on Advanced Information Networking and Applications Workshops - Volume 02 (2007)

In this research, we propose a virtual traditional crafting system that realizes the multimodal communications by using Cave System or Tiled Display over the Next Generation Network. In this system, various places in Japan are connected by a super-high-speed network to construct a presentation system which takes into consideration of human sensitivity for impression to Japanese Traditional crafting in virtual reality environment. Three versions of the Japanese traditional crafting system have been prototyped including PC version, CAVE version and tiled display version were developed. In addition, in there, interactive communications between remote users are enabled by using non-verbal communication information and user's sensibility as an additional information. Thus, a new communications system that integrates the virtual reality space of Japanese traditional crafting system and 3D video images is realized.
From algorithm to first 3.5G call in record time: a novel system design approach based on virtual prototyping and its consequences for interdisciplinary system design teams
Authors: M. Brandenburg, A. Schöllhorn, S. Heinen, J. Eckmüller, T. Eckart
Venue: Proceedings of the conference on Design, automation and test in Europe (2007)

Increasing system complexity not only in wireless communications forces design teams to avoid errors during the process of system refinement thereby keeping ambiguities during system implementation at a minimum. On the other hand the chosen system design approach has to ensure that a system design project rapidly advances through all stages of refinement from an algorithmic model to a real "System on Chip" (SoC) while maintaining backwards equivalence of the produced HW and FW/SW code with the original algorithmic model. This system design challenge also demands a new interdisciplinary team approach encompassing all design skills ranging from concept to HW and FW/SW engineering as well as system verification to increase the overlap in the system concept, implementation and verification phase. But how do these interdisciplinary teams cooperate efficiently, as they are used to metaphorically "speak different design languages"? Resulting in an industry record development time for a 3.5G UMTS modem the employment of a novel system design approach is shown which serves as common system design language, avoiding the babylonian language disaster of isolated engineering worlds. The motivation for an increasing overlap of system concept, implementation and verification phases is obvious: it can save time (to market) in the magnitude of several months or even more and thus drastically shorten design cycles by parallel development of HW and FW/SW. The proposed approach also helps to avoid costly redesign cycles due to conceptual errors and optimizes the quality of the developed system HW and FW/SW thereby also substantially reducing system development R&D costs.

The stochastic CRB for array processing in unknown noise fields
Authors: A. B. Gershman
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 2001. on IEEE International Conference - Volume 05 (2001)

The stochastic Cramer-Rao bound (CRB) plays an important role in array processing because several high-resolution direction-of-arrival (DOA) estimation methods are known to achieve! this bound asymptotically In this paper, we study the stochastic CRB on DOA estimation accuracy in the general case of arbitrary unknown noise field parametrized by a vector of unknowns. We derive explicit closed-form expressions for the CRB and examine its properties theoretically and by representative numerical examples.
Using bilingual ETD collections to mine phrase translations
Authors: Ryan Richardson, Edward A. Fox
Venue: Proceedings of the 7th ACM/IEEE-CS joint conference on Digital libraries (2007)

Phrase translation lists can enhance cross-language information retrieval. However, finding translations for technical phrases is difficult. Bilingual dictionaries have limited coverage for specialized fields, and even more limited coverage of technical phrases. Since phrases can have very specific meanings in technical fields, this limits the quality of translations produced by generic machine translation systems. We hypothesize that digital libraries of electronic theses and dissertations (ETDs) are a good source of technical phrase translations. We have acquired a collection of 3,086 Spanish ETDs about computer science from Scirus, the Universidad Nacional Autónoma de México (Mexico City), and Universidad de las Américas (Puebla). By using English ETDs from NDLTD, we have a comparable corpus of computing-related documents from which to mine phrase translations. We describe our method and its formative evaluation.

Unwrapping phases by relaxed mean field inference
Authors: K. Achan
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 2001. on IEEE International Conference - Volume 03 (2001)

Some types of medical and topographic imaging devices produce images in which the pixel values are "phase-wrapped", i.e., the measured modulus is a known scalar. Phase unwrapping can be viewed as the problem of inferring the number of shifts between each and every pair of neighboring pixels, subject to an a priori preference for smooth surfaces, and subject to a zero curl constraint, which requires that the shifts must sum to 0 around every loop. We formulate phase unwrapping as a mean field inference problem in a probability model, where the prior favors the zero curl constraint. We compare our mean field technique with the least squares method on a synthetic 100/spl times/100 image, and give results on a larger 512/spl times/512 image.

Novel Process and Temperature-Stable BICS for Embedded Analog and Mixed-Signal Test
Authors: John Liobe, Martin Margala
Venue: Proceedings of the 13th IEEE International On-Line Testing Symposium (2007)

This paper proposes a new current sensor design for the arduous task of testing embedded analog and mixed-signal circuits. This proposed, wide-band, minimally-intrusive IDD sensor operates up to 230MHz, which is 2.3X faster than previously proposed designs, and occupies 78.3% less area than another competing design, while achieving an inherent tolerance to process and temperature variations without sacrificing significant area. A BiST utilizing this novel IDD sensor is created and tested on a CMOS op-amp and mixer showing high fault detection sensitivity, while maintaining the performance of the DUT (device-under-test). The experiments are implemented in 0.18ìm TSMC CMOS mixed-signal technology.
Seasonal statistics: The 'seas' package for R
Authors: Michael W. Toews, Paul H. Whitfield, Diana M. Allen
Venue: Computers Geosciences (2007)

The seas package for the R programming environment is capable of conveying descriptive statistics and graphics for seasonal variables, as found in climatology, hydrology and ecology. Seasonal variables can be continuous (e.g., temperature) or discontinuous (e.g., precipitation). An annum can be partitioned into many arbitrary divisions, or seasonal components, such as by month or into other fixed intervals. Boxplots are used to describe the seasonal distributions of continuous variables. Discontinuous variables need to be summed over time to smooth the irregularities before the variable can be evaluated and visualized. Statistics, such as precipitation normals, may be derived from the summed variables, using the mean or median methods. Other tools and utilities provided in the package can calculate precipitation interarrivals, cumulative precipitation departures, find changes between two normals and import data from archive formats.
