Implicit Representations of Space after Bilateral Parietal Lobe Damage
Authors: Min-Shik Kim, Lynn C. Robertson
Venue: Journal of Cognitive Neuroscience (2001)

There is substantial evidence that the primate cortex is grossly divided into two functional streams, an occipital-parietal-frontal pathway that processes "where" and an occipital-temporal-frontal pathway that processes "what" (Ungerleider and Mishkin, 1982). In humans, bilateral occipital-parietal damage results in severe spatial deficits and a neuropsychological disorder known as Balint's syndrome in which a single object can be perceived (simultanagnosia) but its location is unknown (Balint, 1995). The data reported here demonstrate that spatial information for visual features that cannot be explicitly located is represented normally below the level of spatial awareness even with large occipital-parietal lesions. They also demonstrate that parietal damage does not affect preattentive spatial coding of feature locations or complex spatial relationships between parts of a stimulus despite explicit spatial deficits and simultanagnosia.

Bootstrap multiple tests with variance stabilization: application to optimal sensor location
Authors: A. M. Zoubir
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1993. ICASSP-93 Vol 4., 1993 IEEE International Conference on - Volume 04 (1993)

The author reviews and discusses bootstrap methods for testing parameters in situations where sample size tends to be small or the distribution of the test statistic cannot be derived analytically. A bootstrap based variance stabilizing transformation for the parameter under test is considered. This procedure is crucial if the test is to have good power properties and also for the accuracy of the test level. These techniques are applied for comparing multiple coherences, a test which arises in finding optimal sensor locations for knock detection in spark ignition engines. Simulation and experimental results are presented as obtained on a test bed. The tests proposed are multiple tests and permit the finding of optimal positions for sensor groups to control knock in several cylinders at various rotation speeds.
Genderflexing: a theory of gender and socio-scientific learning
Authors: Ricki Goldman-Segall
Venue: Proceedings of the 1996 international conference on Learning sciences (1996)

To better understand the problems preventing non-traditional science students, girls and some boys, from engaging in the study of the natural world, I examine how learners become active in studying scientific issues when the issues are relevant to their lives. To invite learners into thinking about science issues, we introduced the topic of a local endangered rain forest called Clayoquot Sound. For two years, students built a range of paper and multimedia artifacts. This community of investigators made extensive use of analog and digital video, multimedia analysis tools, and the Internet. The results of this ethnography indicate that digital media can become learning environments that support personal, narrative, and relational ways of knowing the world, especially when the content addresses real-world issues. One conclusion I have made is that gender identity is a more flexible construct than has been suggested in previous empirical studies. Both girls and boys need opportunities for "genderflexing" --- for extending beyond traditional epistemological boundaries. While genderflexing, young people learn to cross over boundaries that have previously both defined and confined science education.
Efficient emulation of hardware prefetchers via event-driven helper threading
Authors: Ilya Ganusov, Martin Burtscher
Venue: Proceedings of the 15th international conference on Parallel architectures and compilation techniques (2006)

The advance of multi-core architectures provides significant benefits for parallel and throughput-oriented computing, but the performance of individual computation threads does not improve and may even suffer a penalty because of the increased contention for shared resources. This paper explores the idea of using available general-purpose cores in a CMP as helper engines for individual threads running on the active cores. We propose a lightweight architectural framework for efficient event-driven software emulation of complex hardware accelerators and describe how this framework can be applied to implement a variety of prefetching techniques. We demonstrate the viability and effectiveness of our framework on a wide range of applications from the SPEC CPU2000 and Olden benchmark suites. On average, our mechanism provides performance benefits within 5% of pure hardware implementations. Furthermore, we demonstrate that running event-driven prefetching threads on top of a baseline with a hardware stride prefetcher yields significant speedups for many programs. Finally, we show that our approach provides competitive performance improvements over other hardware approaches for multi-core execution while executing fewer instructions and requiring considerably less hardware support.
Pitfalls in polyspectra
Authors: A. Swami
Venue: Proceedings of the Acoustics, Speech, and Signal Processing, 1993. ICASSP-93 Vol 4., 1993 IEEE International Conference on - Volume 04 (1993)

The area of higher-order statistics (HOS) has witnessed a tremendous resurgence over several years. However, Huber, Kleiner, Gasser and Dumermuth's (1971) observations were that 'the newcomer to the field still has to learn the hard way, from his own mistakes. . .' and 'all the pitfalls known from ordinary spectral analysis occur here too, some of them with new twists. . .'. These continue to be true, despite at least two tutorials, and several special issues of journals. The author examines some of these pitfalls, particularly in the context of deterministic signals observed in noise.
An Add-On for Managing Behaviours with Priority in JADE
Authors: Juan A. Suarez-Romero, Amparo Alonso-Betanzos, Bertha Guijarro-Berdinas
Venue: Proceedings of the IEEE/WIC/ACM international conference on Intelligent Agent Technology (2006)

In this article, two new implementations for behaviours in JADE are presented. These new behaviours, while being able to reproduce the functioning of the old JADE's behaviours, allow the user to define priorities. This fact is of vital importance for several multiagent applications. Finally, a test was developed to show that the performance of the new behaviours is similar to the original ones.
Control of momentum-compaction factor in synchrotron with "resonant" lattice
Authors: Y. Senichev
Venue: Proceedings of the 2003 International Conference on Physics and Control - Volume 3 (2003)

In the construction of different types of synchrotrons we are often restricted in our choice of the momentum compaction factor, which must be kept low enough or negative to satisfy many conditions of beam stability. Some accelerators must have the dispersion-free straight sections desired for RF stations, Siberian Snakes, etc. The dynamic aperture in the presence of chromaticity-correcting sextupoles should be sufficiently large. The theory of momentum compaction factor control is discussed in this article. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

Business processes for web services: principles and applications
Authors: R. Khalaf, A. Keller, F. Leymann
Venue: IBM Systems Journal (2006)

The Business Process Execution Language for Web Services (BPEL4WS or BPEL for short) is an XML-based language for defining business processes that provides an interoperable, portable language for both abstract and executable processes and that was designed from the beginning to operate in the heterogeneity and dynamism that is commonplace in information technology today. BPEL builds on the layers of flexibility provided by the Web Services stack, and especially by XML. In this paper, we provide a brief introduction to BPEL with emphasis on architectural drivers and basic concepts. Then we survey ongoing BPEL work in several application areas: adding quality of service to BPEL, extending BPEL to activities involving humans, BPEL for grid computing, and BPEL for autonomic computing.
iAIML: a Mechanism to Treat Intentionality in AIML Chatterbots
Authors: A. M. M. Neves, F. A. Barros, C. Hodges
Venue: Proceedings of the 18th IEEE International Conference on Tools with Artificial Intelligence (2006)

This paper presents iAIML, a mechanism to treat intentional information based on AIML, a state-of-the-art technology in chatterbot development. Our main goal was to improve dialogues with AIML chatterbots. iAIML adds structure to AIML bases, incorporating intentions and rules used in sentence interpretation and generation. We adopted as linguistic base the Conversational Analysis Theory (CAT), which considers intentionality in adjacent pairs in dialogue, facilitating the establishment of consistent dialogues between chatterbots and users. Tests with the implemented solution showed feasibility of the proposed approach. This is an original work with several contributions, such as the innovative and effective use of CAT, and a consistent modular structure of the iAIML base, favoring reuse and maintenance.

The Roles of Roles in Agent Communication Languages
Authors: Guido Boella, Rossana Damiano, Joris Hulstijn, Leendert van der Torre
Venue: Proceedings of the IEEE/WIC/ACM international conference on Intelligent Agent Technology (2006)

We consider agents having multiple communication sessions at the same time. We assume that FIPA semantics of agent communication languages can still be used when we attribute mental attitudes for each session, which we call the roles of the agents, and we assume that we have to distinguish the mental attitudes attributed to the roles from the mental attitudes of the agents. We consider several consequences of the distinction between the mental attitudes attributed to the roles and the mental attitudes attributed to the agent. First, in attributing mental attitudes to an agent or to one of its roles, we argue that only mental attributes are attributed to an agent's role when these attributes follow directly from the agent's communication. They are therefore public in the sense that every agent who has overheard the session, has the same beliefs about the mental attitudes of the role. Second, the moves permitted to the dialogue participants in the same dialogue game are based on the role only, such that different kind of moves can be specified in different types of dialogue games. Obligations are associated to roles related to institutions which can enforce them by means of sanctions. Third, expectations are based both on the mental attitudes ascribed to the agent and to the role.
Dish_Master: an Intelligent and Adaptive Manager for a Web-based Recipe Database System
Authors: Liping Wang, Qing Li, Yu Li, Xiaofeng Meng
Venue: Proceedings of the Second International Conference on Semantics, Knowledge, and Grid (2006)

In this paper, we describe Dish_Master as an intelligent, adaptive, and cooperative manager for a Web-based recipe database. Dish_Master employs a multi-dimensional knowledge model, adopts a new way of categorizing recipes, and provides a coaching mechanism able to advise the consequences of adopting and adapting an existing recipe from the database. A practical approach using constraints and rules is devised to facilitate the derivation and evaluation of user-specific recipes based on group/global level recipes. The usefulness and elegancy of Dish_Master are demonstrated through an experimental prototype system.
Bias circuit design for low-voltage cascode transistors
Authors: Pablo Aguirre, Fernando Silveira
Venue: Proceedings of the 19th annual symposium on Integrated circuits and systems design (2006)

This article presents a design methodology for the most simple cascode transistor's bias circuit, i.e. a diode-connected transistor, valid from weak to strong inversion. By taking advantage of a compact MOS transistor model, we show how the circuit can be easily designed to precisely fix the drain voltage of the cascoded transistor just above its saturation voltage. Test circuits were manufactured in a 0.35μm CMOS technology in order to test the design methodology under different operation regions (weak, moderate and strong inversion) and for long and short channel transistors. Standard deviation in measured drain voltage of the cascoded transistor is below 3% of its mean.
A Soft Error Tolerant LUT Cascade Emulator
Authors: Hiroki Nakahara, Tsutomu Sasao
Venue: Proceedings of the 15th Asian Test Symposium (2006)

An LUT cascade emulator realizes an arbitrary sequential circuit. Given a sequential circuit, we convert the combinational part into one or more LUT cascades, and store LUT(cell) data into a memory in the LUT cascade emulator. The emulator evaluates multi-output logic functions by reading cell data sequentially. To improve the tolerance to soft errors, cell data in the memory are encoded by error correcting codes. Also, error-correcting circuits and checking circuits that periodically scan the memories are appended. When a soft error is detected, it removes the error by rewriting the correct data into the memory. To mask soft errors in flip-flops, a TMR (Triple Module Redundancy) technique is employed. Our system detects a soft error in a single bit. Also, the mission time of the system is more than 1000x of time of an ordinary LUT cascade emulator.

Authors: Sangwon Chae
Venue: Proceedings of the 37th conference on Winter simulation (2005)

This paper describes a scheduling of Automatic Material Handling System(AMHS) for improving productivity and reducing delivery time. In the paper, we simulate various scenarios and then analyze them for finding the optimal solution. In order to find the optimal solution, we use scenarios of vehicle scheduling and various layouts for AMHS in intra-bay. The paper shows the simulation to improve overall performance on AMHS by reducing the delivery time and raising productivity. The ACM Portal is published by the Association for Computing Machinery.

Control of wheel system with regard for state measurement errors
Authors: V. I. Matyukhin
Venue: Automation and Remote Control (2006)

Consideration was given to the nonholonomic mechanical systems with rolling or the wheel systems. Analysis was confined to the kinematic models. Dynamics of the controlling actuator was taken into account. Consideration was given to the control of a system moving along the given trajectory. The constructed law of control stabilizes this motion as a whole in the main variables. The basic result is concerned with substantiating stability with regard for the errors of measuring the system state.
Modelling and simulation of energy-efficient controllers for pumps within process industry
Authors: V. Vivek, R. P. Kumudini Devi, C. Chellamuthu
Venue: International Journal of Modelling and Simulation (2006)

The submersible pump is one of the major energy-consuming devices on the utility side. This work considers the modelling, simulation, and control of induction motor-driven submersible pump. A non-linear fifth-order model for the motor and a second order for the submersible pump have been used to include nonlinearities such as saturation of magnetic core and eficency of the pump when powered by sinusoidal and VSI-fed voltage source. The discharge of the submersible pump is very difficult to monitor under closed-loop conditions. Hence a discharge estimator is developed based on motor input voltage, line current, and frequency to predict the quantum of water flow under realistic conditions. A closed-loop discharge controller is designed to control discharge without actually monitoring it. A considerable energy savings is obtained in the closed-loop operation.
A (\mu + \lambda) - GP Algorithm and its use for Regression Problems
Authors: Eduardo Oliveira Costa, Aurora Pozo
Venue: Proceedings of the 18th IEEE International Conference on Tools with Artificial Intelligence (2006)

The Genetic Programming (GP) is a powerful technique for Symbolic Regression. However, because it is a new area, many improvements can be obtained changing the basic behavior of the method. In this way, this work develop a different Genetic Programming algorithm doing some modifications on the classical GP algorithm and adding some concepts of Evolution Strategies. The new approach was evaluated using two instances of Symbolic Regression problem -- the Binomial--3 problem (a tunably difficult problem), proposed in [4] and the problem of Modelling Software Reliability Growth (an application of Symbolic Regression). The discovered results were compared with the classical GP algorithm. The Symbolic Regression problems obtained excellent results and an improvement was detected using the proposed approach.
Reading Fluent Speech from Talking Faces: Typical Brain Networks and Individual Differences
Authors: Deborah A. Hall, Clayton Fussell, A. Quentin Summerfield
Venue: Journal of Cognitive Neuroscience (2005)

Listeners are able to extract important linguistic information by viewing the talker's face&mdash;a process known as ''speechreading.'' Previous studies of speechreading present small closed sets of simple words and their results indicate that visual speech processing engages a wide network of brain regions in the temporal, frontal, and parietal lobes that are likely to underlie multiple stages of the receptive language system. The present study further explored this network in a large group of subjects by presenting naturally spoken sentences which tap the richer complexities of visual speech processing. Four different baselines (blank screen, static face, nonlinguistic facial gurning, and auditory speech) enabled us to determine the hierarchy of neural processing involved in speechreading and to test the claim that visual input reliably accesses sound-based representations in the auditory cortex.In contrast to passively viewing a blank screen, the static-face condition evoked activation bilaterally across the border of the fusiform gyrus and cerebellum, and in the medial superior frontal gyrus and left precentral gyrus (p < .05, whole brain corrected). With the static face as baseline, the gurning face evoked bilateral activation in the motion-sensitive region of the occipital cortex, whereas visual speech additionally engaged the middle temporal gyrus, inferior and middle frontal gyri, and the inferior parietal lobe, particularly in the left hemisphere. These latter regions are implicated in lexical stages of spoken language processing. Although auditory speech generated extensive bilateral activation across both superior and middle temporal gyri, the group-averaged pattern of speechreading activation failed to include any auditory regions along the superior temporal gyrus, suggesting that f luent visual speech does not always involve sound-based coding of the visual input.An important finding from the individual subject analyses was that activation in the superior temporal gyrus did reach significance (p < .001, small-volume corrected) for a subset of the group. Moreover, the extent of the left-sided superior temporal gyrus activity was strongly correlated with speechreading performance. Skilled speechreading was also associated with activations and deactivations in other brain regions, suggesting that individual differences ref lect the efficiency of a circuit linking sensory, perceptual, memory, cognitive, and linguistic processes rather than the operation of a single component process.
Multicast Partition Problem for Smart Home Applications
Authors: Jeong-Jun Suh, Shan Guo Quan, Jong-Kuk Park, Jong Hyuk Park, Young Yong Kim
Venue: Proceedings of the 2006 International Conference on Hybrid Information Technology - Volume 02 (2006)

In smart home, multimedia services can be provided to users, who want to receive multimedia data through mobile phones. Most of multimedia applications are implemented using the streaming technique from contents provider to subscribers. It is important to manage the buffering amount remained in the user side in order to support the adequate quality of video contents and minimize complaints of subscribers due to buffer starvation. In the wireless environment, it is difficult to provide several subscribers with multicast traffic stably, since the data rate which users can receive varies according to the channel state of each user. Therefore, we propose and discuss an efficient usage together with MIU (Multicast In Unicast portion) as well as MIM (Multicast In Multicast portion) in order to maximize the aggregate throughput of users and minimize the starvation duration degrading QoS supported to users. We consider the multicast partitioning problem applying list partitioning algorithm and provide the analytical foundation that the proposed scheme can be evaluated. Simulation results show that proposed model can provide enhanced performance and allowed streaming quality.
