A cross-junction channel valveless-micropump with PZT actuation
Authors: Van Thanh Dau, Thien Xuan Dinh, Tanaka Katsuhiko, Sugiyama Susumu
Venue: Microsystem Technologies (2009)

A gas-jet micro pump with novel cross-junction channel has been designed and fabricated using a Si micromachining process. The valveless micro pump is composed of a piezoelectric lead zirconate titanate (PZT) diaphragm actuator and fluidic network. The design of the valveless pump focuses on a cross-junction formed by the neck of the pump chamber and one outlet and two opposite inlet channels. The structure of cross-junction allows differences in fluidic resistance and fluidic momentum inside the channels during each PZT diaphragm vibration cycle, which leads to the gas flow being rectified without valves. The flow channels were easily fabricated by using silicon etching process. To investigate the effects of the structure of the cross-junction on the gas flow rate, two types of pump with different cross-junction were studied. The design and simulation were done using ANSYS-Fluent software. The simulations and experimental data revealed that the step-nozzle structure is much more advantageous than the planar structure. A flow rate of 5.2&#x00a0;ml/min was obtained for the pump with step structure when the pump was driven at its resonant frequency of 7.9&#x00a0;kHz by a sinusoidal voltage of 50&#x00a0;Vp&#x2013;p.
A Discretization Process in Accordance with a Qualitative Ordered Output
Authors: Francisco J. Ruiz, Cecilio Angulo, Núria Agell, Xari Rovira, Mónica Sánchez, Francesc Prats
Venue: Proceeding of the 2005 conference on Artificial Intelligence Research and Development (2005)

This paper lies within the domain of supervised discretization methods. The methodology aims at identifying relevant interactions between input and output variables. A new supervised discretization algorithm that takes into account the qualitative ordinal structure of the output variable is proposed. Most existing supervised discretization methods are designed for pattern recognition problems and do not take into account this ordinal structure. A qualitative distance is constructed over the discrete structure of absolute orders of magnitude spaces. The algorithm presented implements a maximization process of this distance. A simple example allows interpretation of the process of choosing landmarks.
On Ontology, ontologies, Conceptualizations, Modeling Languages, and (Meta)Models
Authors: Giancarlo Guizzardi
Venue: Proceeding of the 2007 conference on Databases and Information Systems IV: Selected Papers from the Seventh International Baltic Conference DB&IS'2006 (2007)

In philosophy, the term ontology has been used since the 17th century to refer both to a philosophical discipline (Ontology with a capital “O”), and as a domain-independent system of categories that can be used in the conceptualization of domain-specific scientific theories. In the past decades there has been a growing interest in the subject of ontology in computer and information sciences. In the last few years, this interest has expanded considerably in the context of the Semantic Web and MDA (Model-Driven Architecture) research efforts, and due to the role ontologies are perceived to play in these initiatives. In this paper, we explore the relations between Ontology and ontologies in the philosophical sense with domain ontologies in computer science. Moreover, we elaborate on formal characterizations for the notions of ontology, conceptualization and metamodel, as well as on the relations between these notions. Additionally, we discuss a set of criteria that a modeling language should meet in order to be considered a suitable language to model phenomena in a given domain, and present a systematic framework for language evaluation and design. Furthermore, we argue for the importance of ontology in both philosophical senses aforementioned for designing and evaluating a suitable general ontology representation language, and we address the question whether the so-called Ontology Web languages can be considered as suitable general ontology representation languages. Finally, we motivate the need for two complementary classes of modeling languages in Ontology Engineering addressing two separate sets of concerns.
Dual confocal laser-induced fluorescence/moveable contactless conductivity detector for capillary electrophoresis microchip
Authors: Feng Shen, Yong Yu, Meng Yang, Qi Kang
Venue: Microsystem Technologies (2009)

A new dual simultaneous detector was developed for capillary electrophoresis microchip. Confocal laser-induced fluorescence (LIF) and moveable contactless conductivity detection (MCCD) were combined together for the first time. The two detection systems shared a common detection cell and could respond simultaneously. They were mutually independent and advantageous in analyses of mixtures containing organic and inorganic ions. The confocal LIF had high sensitivity and the MCCD could move along the separation channel and detect in different positions of the channel. The detection conditions of the dual detector were optimized. Rhodamine B was used to evaluate the performance of the dual detector. The limit of detection of the confocal LIF was <5&#x00a0;nM, and that of the MCCD was 0.1&#x00a0;&#x03bc;M. The dual detector had highly sensitivity and could offer response easily, rapidly and simultaneously.

Authors: Shuvra S. Bhattacharyya, Gordon Brebner, Jörn W. Janneck, Johan Eker, Carl von Platen, Marco Mattavelli, Mickaël Raulet
Venue: ACM SIGARCH Computer Architecture News (2009)

This paper presents the OpenDF framework and recalls that dataflow programming was once invented to address the problem of parallel computing. We discuss the problems with an imperative style, von Neumann programs, and present what we believe are the advantages of using a dataflow programming model. The CAL actor language is briefly presented and its role in the ISO/MPEG standard is discussed. The Dataflow Interchange Format (DIF) and related tools can be used for analysis of actors and networks, demonstrating the advantages of a dataflow approach. Finally, an overview of a case study implementing an MPEG- 4 decoder is given.

Designing a fuzzy system for controlling the armament fire in dynamic siege
Authors: R. Tavakkoli-Moghaddam, N. Safaei, A. Azaron
Venue: Expert Systems with Applications: An International Journal (2009)

This paper presents a fuzzy system for controlling the fire command in a surface-to-surface engagement by assuming siege of friendly side by enemy forces. The system must be capable of interacting with a dynamic and uncertain battle world in a real-time manner. In siege situation, it is assumed that the enemy troops are advancing toward friendly side in different directions and the defence resources are limited and nonrenewable at a single platform. Thus, resource allocation problem in a real-time manner is an important and vital component of battle management until coming of auxiliary forces. This paper addresses the design of a fuzzy system as an efficient tool for real-time decision-making in order to optimize the defense resource allocation in engagement.
Reverse Engineering: An Industrial Perspective, 1st edition
Authors: Vinesh Raja, Kiran J. Fernandes
Venue:  (2007)

Reverse engineering is the process of discovering the technological principles of an object or component through analysis of its structure and function. Such analysis can then be used to redesign the object very quickly using computer-aided design in concert with rapid-manufacturing processes to produce small numbers of components adapted to the needs of a particular customer. This way of working has huge benefits of speed and flexibility over traditional mass-production-based design and manufacturing processes. This edited collection of essays from world-leading academic and industrial authors yields insight into all aspects of reverse engineering: The methods of reverse engineering analysis are covered, with special emphasis on the investigation of surface and internal structures. Frequently-used hardware and software are assessed and advice given on the most suitable choice of system. Rapid prototyping is introduced and its relationship with successful reverse engineering is discussed. Importantly, legal matters surrounding reverse engineering are addressed as are other barriers to the adoption of these techniques. Applications of reverse engineering in three significant areas: automotive, aerospace, and medical engineering are reported in depth. Reverse Engineering is a "must have" title for anyone working with advanced modern manufacturing technologies, either with a view to researching and improving them further or to making their company leaner and more agile in a competitive manufacturing marketplace.

The highlight of this paper is the SWOT / TOWS matrix from which in future, the researchers may spell-out the ways to achieve the success of M-Commerce in the long-term.
The impact of betweenness in small world networks on request for proposal coalition formation problems
Authors: Carlos Merida-Campos, Steven Willmott
Venue: Proceeding of the 2007 conference on Artificial Intelligence Research and Development (2007)

The analysis of societies demonstrates the recurrent nature of small world topology in the interactions of elements in such worlds. The small world topology proves to have beneficial properties for system's performance in many cases, however there are also scenarios where the small world topology's properties negatively affect the system's outcome; thus in depth knowledge on the small world weaknesses is needed in order to develop new generations of artificial societies and new models of economic systems. In this paper, a multi-agent system based on request for proposal protocol and coalition formation organisational paradigm is used to analyse properties of small world social networks of agents. Experiments center on nodes in the network with high betweenness and in particular the distribution of agents in the population across these nodes. Results show that small world topology scenarios lose their beneficial properties when non-competitive agents are positioned as high betweeness nodes in the network.
Polyhedral outer approximations with application to natural language parsing
Authors: André F. T. Martins, Noah A. Smith, Eric P. Xing
Venue: Proceedings of the 26th Annual International Conference on Machine Learning (2009)

Recent approaches to learning structured predictors often require approximate inference for tractability; yet its effects on the learned model are unclear. Meanwhile, most learning algorithms act as if computational cost was constant within the model class. This paper sheds some light on the first issue by establishing risk bounds for max-margin learning with LP relaxed inference and addresses the second issue by proposing a new paradigm that attempts to penalize "time-consuming" hypotheses. Our analysis relies on a geometric characterization of the outer polyhedra associated with the LP relaxation. We then apply these techniques to the problem of dependency parsing, for which a concise LP formulation is provided that handles non-local output features. A significant improvement is shown over arc-factored models.
Anchored Narratives in Reasoning about Evidence
Authors: Floris Bex, Henry Prakken, Bart Verhey
Venue: Proceeding of the 2006 conference on Legal Knowledge and Information Systems: JURIX 2006: The Nineteenth Annual Conference (2006)

This paper concerns the reasoning with stories, evidence and generalisations in a legal context. We will make some notions from the existing Anchored Narratives theory more clear by making use of two formal techniques from AI, namely causal-abductive reasoning and default-style argumentation. We will propose a combination of these two formalisms which solves some of the problems of the causal-abductive approach.
Second international workshop on Layout of (Software) Engineering diagrams (LED'08)
Authors: Andrew Fish, Harald Storrle
Venue: Proceedings of the 2008 IEEE Symposium on Visual Languages and Human-Centric Computing (2008)

Traditionally, diagrams play an important role in many disciplines from electrical engineering (e.g. Karnaugh diagrams), civil and mechanical engineering (construction plans), geography (maps), and so on. In Software Engineering, diagrammatic languages like IDEF, UML or ARIS are commonplace today. With the rise of model driven development and domain specific languages, such languages will be even more widespread in the future. All in all, diagrams play an important role in the communication among engineers.
Development of Specialized e-Learning Materials with Simulators for Engineering Education and Practice in University
Authors: Takahiro Masuda, Hiroshi Suda, Yoshiro Miida
Venue: Proceeding of the 2007 conference on Supporting Learning Flow through Integrative Technologies (2007)

The construction of the network infrastructure and environments of e-Learning have advanced. Securing a qualitative guarantee of a so-called education by using LMS (Learning Management System) in the higher education organization became possible. However, because the education which passes the experiment and the practice is indispensable, e-Learning has not been taken easily in the engineering education. Since engineering universities educate a lot of invisibility phenomenon for example electrical signals and sound field. We are developing multimedia materials by real-time simulation technique, so that students understand visually them. Moreover, we affirm practice on the e-Learning portal and LMS of the university. In this paper, we describe developing E-learning for engineering university multimedia materials, moreover, practice in e-Learning system of Chiba Institute of Technology (CIT).
802.11 wireless experiments in a virtual world
Authors: Thomas Sturgeon, Colin Allison, Alan Miller
Venue: ACM SIGCSE Bulletin (2009)

This paper describes the design and implementation of an 802.11 wireless laboratory within a Multi-User Virtual Environment (MUVE). The laboratory allows students and lecturers to create their own 802.11 scenarios by: i) selecting and placing components such as base stations and laptops within the immersive 3D landscape; ii) defining how traffic flows between these different network components; and iii) where appropriate specifying the movements of nodes. This information is sent outside of the MUVE and translated into a set of commands for the ns2 simulator, which then generates the simulation. The results of the simulation are sent back to the MUVE, where a 3D animation of the wireless communication is presented to learners interacting with the system. Learners are therefore able to set up and observe wireless phenomena such as the hidden and exposed node problems and to experiment by changing parameters such as packet loss and RTS/CTS threshold. The enabling framework behind the laboratory takes advantage of language independent, distributed resource management and stateful interaction through the use of web services.
Generating Believable Personality-Rich Story Characters Using Body Languages
Authors: Wen-Poh Su, Binh Pham, Aster Wardhani
Venue: Proceeding of the 2006 conference on Advances in Intelligent IT: Active Media Technology 2006 (2006)

We present an approach using story scripts and action descriptions in a form similar to the content description of storyboards to predict specific personality and emotional states. By constructing a hierarchical fuzzy rule-based system we facilitate the personality and emotion control of the body language of dynamic story characters. Our ultimate goal is to facilitate the high-level control of synthetic characters.
Semantic discourse segmentation and labeling for route instructions
Authors: Nobuyuki Shimizu
Venue: Proceedings of the 21st International Conference on computational Linguistics and 44th Annual Meeting of the Association for Computational Linguistics: Student Research Workshop (2006)

In order to build a simulated robot that accepts instructions in unconstrained natural language, a corpus of 427 route instructions was collected from human subjects in the office navigation domain. The instructions were segmented by the steps in the actual route and labeled with the action taken in each step. This flat formulation reduced the problem to an IE/Segmentation task, to which we applied Conditional Random Fields. We compared the performance of CRFs with a set of hand-written rules. The result showed that CRFs perform better with a 73.7% success rate.
Enhancement of Blurred and Noisy Images Based on an Original Variant of the Total Variation
Authors: Khalid Jalalzai, Antonin Chambolle
Venue: Proceedings of the Second International Conference on Scale Space and Variational Methods in Computer Vision (2009)

In this paper, we introduce a new variant of the total variation (TV). Its purpose is to simplify TV-based restoration when the image is degraded by some kernel which is easily computed in the Fourier domain (blur, Radon transform...). We actually replace the TV term by a mere L 1 norm of some field, for which the optimization is much easier. This approach permits us to use a recent and fast algorithm to enhance, in particular, blurred and noisy images. We also compare our approach with standard total variation based denoising and show that it avoids the famous staircasing effect.

Statechart DNA
Authors: Benjamin De Leeuw, Albert Hoogewijs
Venue: Proceedings of the 10th WSEAS international conference on Automation & information (2009)

We introduce and explore a new statechart (sc) abstraction method and define a simplified statechart (ssc) model. We study the basic building blocks (so the term 'DNA') of UML sc models. Within this formal approach, we untangle the object-oriented concepts characterizing the UML. We treat triggers, guards and effects as related to each other, but make no reference to any explicit value (type) in the computation. This abstract approach allows us to introduce mathematical manipulations of UML sc, in line with the theory of regular automata. Statechart DNA has been applied in defining complexity metrics for UML sc models, the automatic generation of model test cases and behavior manipulations in CASE tool environments.
A Conceptual Model Makes Curriculum Evolution in Higher Education Smooth
Authors: Wenhuan Lu, Mitsuru Ikeda, Koichiro Ochimizu, Shintaro Kitayama
Venue: Proceeding of the 2007 conference on Supporting Learning Flow through Integrative Technologies (2007)

Curriculum changes over time. In practice, it is not easy to keep a curricular system updated and to provide students with reliable course services that reflect and correspond to the evolutions of curriculum. This study is a step toward supporting a smooth curriculum evolution process with Ontology-aware Course Consulting (On2C) system through the use of Artificial Intelligent techniques to assist different stakeholders involved. Our approach contributes to a recently emerging trend for incorporating intelligent techniques in Intelligent Education System. In this paper a model of the evolutionary process has been proposed, which reflects the essential structure of curriculum for offering a better way to track the history of curriculum change. Curriculum ontology we developed serves as a fixed conceptual system to fully predict the generic components of curriculum, so this ontology can be reused in situation-dependent curriculum systems.
Keyword query cleaning using hidden Markov models
Authors: Ken Q. Pu
Venue: Proceedings of the First International Workshop on Keyword Search on Structured Data (2009)

In this paper, we consider the problem of keyword query cleaning for structured databases from a probabilistic approach. Keyword query cleaning consists of rewriting the user query, segmenting the keywords, matching each segment to database items, and finally tagging the segments by their meta-data information. We present an efficient and robust solution using Hidden Markov Models (HMM). By modeling user keyword queries using a generative probabilistic HMM-based model, we construct a HMM from the user specified keyword query (and the database instance). The optimal statistical keyword cleaning is computed as the most likely path of the constructed HMM. Furthermore, we demonstrate how the optimal HMM-based keyword cleaning algorithm can be generalized to compute a stream of clean queries ranked from the most likely clean query to the least likely clean query. Finally, we present the implementation of the proposed system and its preliminary performance.
