Energy Metrics and Sustainability
Authors: Mory Ghomshei, Francesco Villecco
Venue: Proceedings of the International Conference on Computational Science and Its Applications: Part I (2009)

Early human civilizations developed along water corridors. With increasing dependency of human activities on energy, sustainability of future civilizations would be largely linked to sustainability of energy resources and systems. The tie between energy and socio-environmental sustainability, though obvious remains nebulous mostly because, neither energy nor sustainability are clearly defined. While thermodynamic definition of energy is relatively clear, its nature (as linked to human activities and sustainable development) is not well understood. This paper is an attempt to present a metric for the components and attributes of energy resources and technologies as interfaced with human civilization. A fuzzy logic model is used to scale energy systems based on their valued attributes (such as storability, transformability, quality, transportability, availability, environmental value and resource sustainability). The model is used to predict future energy corridors and their association with economical growth and sustainability. It is shown that green energy systems should be developed not in isolation but integrated in intelligent "synergetic" systems to meet the energy demands of future human civilizations.

Authors: Serge Parshutin, Ludmila Aleksejeva, Arkady Borisov
Venue: Proceedings of the 9th Industrial Conference on Advances in Data Mining. Applications and Theoretical Aspects (2009)

Management of the product life cycle and of the corresponding supply network largely depends on information in which specific phase of the life cycle one or another product currently is and when the phase will be changed. Finding a phase of the product life cycle can be interpreted as forecasting transition points between phases of life cycle of these products. This paper provides a formulation of the above mentioned task of forecasting the transition points and presents the structured data mining system for solving that task. The developed system is based on the analysis of historical demand for products and on information about transitions between phases in life cycles of those products.The experimental results with real data display information about the potential of the created system.

Eye tracking under naturalistic viewing conditions may provide a means to assess operator workload in an unobtrusive manner. Specifically, we explore the use of a nearest neighbor index of workload calculated using eye fixation patterns obtained from operators navigating an unmanned ground vehicle under different task loads and levels of automation. Results showed that fixation patterns map to the operator's experimental condition suggesting that systematic eye movements may characterize each task. Further, different methods of calculating the workload index are highly correlated, r(46) = .94, p = .01. While the eye movement workload index matches operator reports of workload based on the NASA TLX, the metric fails on some instances. Interestingly, these departure points may relate to the operator's perceived attentional control score. We discuss these results in relation to automation triggers for unmanned systems.

Authors: Martin Inderbitzin, Sytse Wierenga, Aleksander V&#x00e4;ljam&#x00e4;e, Ulysses Bernardet, Paul F. M. J. Verschure
Venue: Virtual Reality (2009)

Although the architecture of mixed reality spaces is becoming increasingly more complex, our understanding of human behavior in such spaces is still limited. Despite the sophisticated methods deployed in ethology and behavioral biology to track and analyze the actions and movements of animals, we rarely find studies that focus on the understanding of human behavior using such instruments. Here, we address this issue by analyzing social behavior and physical actions of multiple humans who are engaging in a game. As a paradigm of social interaction, we constructed a mixed reality football game in which two teams of two players have to cooperate and compete in order to win. This paradigm was deployed in the, so-called, eXperience Induction Machine (XIM), a human accessible, fully instrumented space that supports full body interaction in mixed reality without the need for body-mounted sensors. Our results show that winning and losing strategies can be discerned by specific behavioral patterns and proxemics. This demonstrates that mixed reality systems such as XIM provide new paradigms for the investigation of human social behavior.

A study regarding the use of the semantic Web technologies within complex systems – distributed file systems, Grid platforms and wiki-like applications – is presented from the perspective of the knowledge management, especially the modeling of the implicated resources. Several case studies are described, involving the use of actual semantic Web model, languages, and technologies – including microformats and ontologies – to express knowledge in the context of the distributed systems.
Soft-sensor Modeling of Cement Raw Material Blending Process Based on Fuzzy Neural Networks with Particle Swarm Optimization
Authors: Xinggang Wu, Mingzhe Yuan, Haibin Yu
Venue: Proceedings of the 2009 International Conference on Computational Intelligence and Natural Computing - Volume 02 (2009)

By combining particle swarm optimization algorithm (PSO) with fuzzy neural networks (FNN), a PSO fuzzy neural networks (PSO-FNN) was proposed, which takes full advantage of the global search ability of particle swarm optimization (PSO) algorithm and the local search ability of conjugate gradient algorithm with constraints. The new method assumed that FNN was used to construct the model of cement raw material blending process, while PSO was employed to optimize parameters of FNN. Experiment results show that the model based on PSO-FNN has higher precision and better performance than the model based on BPNN.
Synthesis of constraint-based local search algorithms from high-level models
Authors: Pascal Van Hentenryck, Laurent Michel
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 1 (2007)

The gap in automation between MIP/SAT solvers and those for constraint programming and constraint-based local search hinders experimentation and adoption of these technologies and slows down scientific progress. This paper addresses this important issue: It shows how effective local search procedures can be automatically synthesized from models expressed in a rich constraint language. The synthesizer analyzes the model and derives the local search algorithm for a specific meta-heuristic by exploiting the structure of the model and the constraint semantics. Experimental results suggest that the synthesized procedures only induce a small loss in efficiency on a variety of realistic applications in sequencing, resource allocation, and facility location.

Authors: Jing Pang, Shitalben Chauhan, Jay Maheshkumar Bhlodia
Venue: Proceedings of the Advances in Electrical and Electronics Engineering - IAENG Special Edition of the World Congress on Engineering and Computer Science 2008 (2008)

Compared with the traditional digital signal processor, the Field Programmable Gate Array (FPGA) has advantages of configurable datapath, low cost, reprogrammability, and high performance. As a result, the FPGA device becomes more and more popular in the field of digital signal processing applications. This paper presents FPGA design of speech compression by using different discrete wavelet transform (DWT) schemes including the Daubechies DWT and the Daubechies Lifting Scheme DWT. In this design work, the audio CODEC chip is used to convert analog speech into the digital format. The digital streams can either be stored inside the SDRAM for DWT postprocessing or compressed in real time by using the Daubechies Lifting Scheme DWT. The low pass filtering part of the DWT result represents the compressed speech. It can be read back from the SDRAM, converted to analog signal and then played clearly in speakers after upsampling is performed.
A Study on a Method to Call Drivers' Attention to Hazard
Authors: Hiroshi Takahashi
Venue: Proceedings of the 8th International Conference on Engineering Psychology and Cognitive Ergonomics: Held as Part of HCI International 2009 (2009)

This paper presents a new warning method for increasing drivers' sensitivity for recognizing hazardous factors in the driving environment. The method is based on a subliminal effect. The results of many experiments performed with six subjects show that the response time for detecting a flashing mark tended to decrease when a subliminal mark was shown in advance. This paper also proposes a scenario for implementing this method in real vehicles.
Hardware Accelerator for the Tate Pairing in Characteristic Three Based on Karatsuba-Ofman Multipliers
Authors: Jean-Luc Beuchat, Jérémie Detrey, Nicolas Estibals, Eiji Okamoto, Francisco Rodríguez-Henríquez
Venue: Proceedings of the 11th International Workshop on Cryptographic Hardware and Embedded Systems (2009)

This paper is devoted to the design of fast parallel accelerators for the cryptographic Tate pairing in characteristic three over supersingular elliptic curves. We propose here a novel hardware implementation of Miller's loop based on a pipelined Karatsuba-Ofman multiplier. Thanks to a careful selection of algorithms for computing the tower field arithmetic associated to the Tate pairing, we manage to keep the pipeline busy. We also describe the strategies we considered to design our parallel multiplier. They are included in a VHDL code generator allowing for the exploration of a wide range of operators. Then, we outline the architecture of a coprocessor for the Tate pairing over $\mathbb{F}_{3^m}$. However, a final exponentiation is still needed to obtain a unique value, which is desirable in most of the cryptographic protocols. We supplement our pairing accelerator with a coprocessor responsible for this task. An improved exponentiation algorithm allows us to save hardware resources.According to our place-and-route results on Xilinx FPGAs, our design improves both the computation time and the area-time trade-off compared to previoulsy published coprocessors.

Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

Due to inherent dynamic nature of Mobile Ad-hoc Networks (MANETs), real time communication and Quality of Service (QoS) is very difficult to achieve. For achieving QoS and real time transmission of audio video data, location information of node can help to achieve an efficient, robust routing and optimal communication link between source and destination. In this paper we are inspired by the usage of GPS data to reduce routing delay & efficient information dissemination. Location Information is utilized to geocast the request rather than broadcast route request in AODV-UU, subsequently reducing the number of broadcasts (routing overhead). This eventually helps to reduce the flooding of packets in the network for route discovery.

Venue: Proceedings of the 20th national conference on Artificial intelligence - Volume 4 (2005)

This thesis work aims at improving the problem solving ability of the Gene Expression Programming (GEP) algorithm to fulfill complex data mining tasks by preserving and utilizing the self-emergence of structures during its evolutionary process. The main contributions include the investigation of the constant creation techniques for promoting good functional structures emergent in the evolution, analysis of the limitation with the current implementation scheme of GEP, and introduction of a novel utilization of the emergent structures to achieve a flexible search process for solutions at a higher level.
Strong and Weak Policy Relations
Authors: Michael J. May, Carl A. Gunter, Insup Lee, Steve Zdancewic
Venue: Proceedings of the 2009 IEEE International Symposium on Policies for Distributed Systems and Networks (2009)

Access control and privacy policy relations tend to focus on decision outcomes and are very sensitive to defined terms and state. Small changes or updates to a policy language or vocabulary may make two similar policies incomparable. To address this we develop two flexible policy relations derived from bisimulation in process calculi. Strong licensing compares the outcome of two policies strictly, similar to strong bisimulation. Weak licensing compares the outcome of policies more flexibly by ignoring irrelevant (non-conflicting)differences between outcomes, similar to weak bisimulation. We illustrate the relations using examples from P3P.

Authors: Karla Conn Welch, Uttama Lahiri, Changchun Liu, Rebecca Weller, Nilanjan Sarkar, Zachary Warren
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

This paper describes the design and development of both software to create social interaction modules on a virtual reality (VR) platform and individualized affective models for affect recognition of children with autism spectrum disorders (ASD), which includes developing tasks for affect elicitation and using machine-learning mathematical tools for reliable affect recognition. A VR system will be formulated that can present realistic social communication tasks to the children with ASD and can monitor their affective response using physiological signals, such as cardiovascular activities including electrocardiogram, impedance cardiogram, photoplethysmogram, and phonocardiogram; electrodermal activities including tonic and phasic responses from galvanic skin response; electromyogram activities from corrugator supercilii, zygomaticus major, and upper trapezius muscles; and peripheral temperature. This affect-sensitive system will be capable of systematically manipulating aspects of social communication to more fully understand its salient components for children with ASD.

Fast Implementation of the Ultimate Opening
Authors: Jonathan Fabrizio, Beatriz Marcotegui
Venue: Proceedings of the 9th International Symposium on Mathematical Morphology and Its Application to Signal and Image Processing (2009)

We present an efficient implementation of the ultimate attribute opening operator. In this implementation, the ultimate opening is computed by processing the image maxtree representation. To show the efficiency of this implementation, execution time is given for various images at different scales. A quasi-linear dependency with the number of pixels is observed. This new implementation makes the ultimate attribute opening usable in real time. Moreover, the use of the maxtree allows us to process specific zones of the image independently, with a negligible additional computation time.
Minimal Message Complexity of Asynchronous Multi-party Contract Signing
Authors: Sjouke Mauw, Sasa Radomirovic, Mohammad Torabi Dashti
Venue: Proceedings of the 2009 22nd IEEE Computer Security Foundations Symposium (2009)

Multi-party contract signing protocols specify how a number of signers can cooperate in achieving a fully signed contract, even in the presence of dishonest signers. This problem has been studied in different settings, yielding solutions of varying complexity. Here we assume the presence of a trusted third party that will be contacted only in case of a conflict, asynchronous communication, and a total ordering of the protocol steps. Our goal is to develop a lower bound on the number of messages in such a protocol. Using the notion of abort chaining, a specific type of attack on fairness of signing protocols, we derive the lower bound alpha^2 + 1, with alpha being the number of signers involved. We obtain the lower bound by relating the problem of developing fair signing protocols to the open combinatorial problem of finding shortest permutation sequences. This relation also indicates a way to construct signing protocols which are shorter than state-of-the-art protocols. We illustrate our approach by presenting the shortest three-party fair contract signing protocol.
