Ontology-based data mining approach implemented on exploring product and brand spectrum
Authors: Shu-hsien Liao, Hsu-hui Ho, Feng-chich Yang
Venue: Expert Systems with Applications: An International Journal (2009)

In physics, a spectrum is, the series of colored bands diffracted and arranged in the order of their respective wave lengths by the passage of white light through a prism or other diffracting medium. Outside of physics, a spectrum is a condition that is not limited to a specific set of values but can vary infinitely within a continuum. In commerce, an effective visualization tool, especially for stakeholders or managers, is a brand spectrum diagram highlighting where the company's brands and products are situated compared to other competitors. This paper investigates the research issues on product and brand spectrum in the beverage product market of Taiwan, which proposes using the Apriori algorithm of association rules, and clustering analysis based on an ontology-based data mining approach, for mining customer and product knowledge from the database. Knowledge extracted from data-mining results is illustrated as knowledge patterns, rules, and maps in order to propose suggestions and solutions to beverage firms for possible product development, promotion, and marketing.
Sustaining Pervasive Integration of ICT into Curriculum through Peer Coaching
Authors: Gan Poh Choo, Chua Meng Joo
Venue: Proceeding of the 2007 conference on Supporting Learning Flow through Integrative Technologies (2007)

This paper explores how collaborative peer coaching could be used effectively as an intervention strategy to sustain the integration of Information and Communication Technology (ICT) into the school curriculum. 'ICT Peer Coaching' is a strategy designed to promote and sustain the use of ICT in teaching and learning through collaborative peer coaching among teachers. The results of an eight-month study (Feb to Sep 2004) of this intervention strategy showed teachers' increased affinity towards the use of ICT as more ICT-integrated lessons were conducted in both the computer labs and the classrooms. The variety of research methods used to determine the outcome of ICT Peer Coaching included surveys, face-to-face interviews and monitoring the frequency of computer usage by students. The findings of this study bear certain implications for Singapore schools in the area of teacher development. It calls for a review of the potential of peer coaching and the innovative adoption of peer coaching approaches to promote collaborative reflection among teachers to support their venture into ICT integration. The synergy resulting from the collaborative and reflective practice provided teachers with the much needed peer-support and collegial encouragement that sustained them through the challenge of reframing learning with ICT.
A wide-beam array antenna using shorted-end curved dipoles on a reflector plane
Authors: Rangsan Wongsan
Venue: WSEAS TRANSACTIONS on COMMUNICATIONS (2009)

This paper presents a wide-beam array antenna for broadcasting station by using two curved dipoles, which its both ends of each dipole are electrically shorted on the surface of a square conducting reflector and connected to the ground system and the feed point is excited at the center of each one. Advantage of this antenna should possess physically strong structure, easy fabrication, and cost effectiveness. Because of the elements of array are made of the straight dipoles, which their arms are curved for enlarging the beamwidth and shorted on a metallic reflector for increasing total directive gain and robusting the structure. The Method of Moment (MoM) is utilized to solve numerically the electrical currents that distribute along the curved dipole, which are used to determine the impedance characteristics and the radiation patterns of this antenna. The beamwidth of azimuth pattern of the proposed antenna is around 120°, which is suitable for achieving omnidirectional pattern for TV broadcasting station by placing them around the tower at least three panels. Having confirmed the validity of this approach, the UHF-band antenna prototype is fabricated, tested experimentally and shows good performance.
Flexible and Efficient Use of Robot Resources Using Higher-Order Mobile Agents
Authors: Mayu Mizuno, Masato Kurio, Munehiro Takimoto, Yasushi Kambayashi
Venue: Proceeding of the 2006 conference on Knowledge-Based Software Engineering: Proceedings of the Seventh Joint Conference on Knowledge-Based Software Engineering (2006)

This paper presents a framework for controlling intelligent robots connected by communication networks. This framework provides novel methods to control coordinated systems using higher-order mobile agents. Higher-order mobile agents are hierarchically structured agents that can contain other mobile agents. The combination of the higher-order mobile agent and mobile multi-robots open a new horizon of efficient use of mobile robot resources. Instead of physical movement of multi-robot, mobile software agents can migrate from one robot to another so that they can find the most suitably equipped and/or the most suitably located robots to perform their task. Thus the framework presented here provides efficient use of robot resources as well as scalability and flexibility.
Covariate Analysis for View-Point Independent Gait Recognition
Authors: I. Bouchrika, M. Goffredo, J. N. Carter, M. S. Nixon
Venue: Proceedings of the Third International Conference on Advances in Biometrics (2009)

Many studies have shown that gait can be deployed as a biometric. Few of these have addressed the effects of view-point and covariate factors on the recognition process. We describe the first analysis which combines view-point invariance for gait recognition which is based on a model-based pose estimation approach from a single un-calibrated camera. A set of experiments are carried out to explore how such factors including clothing, carrying conditions and view-point can affect the identification process using gait. Based on a covariate-based probe dataset of over 270 samples, a recognition rate of 73.4% is achieved using the KNN classifier. This confirms that people identification using dynamic gait features is still perceivable with better recognition rate even under the different covariate factors. As such, this is an important step in translating research from the laboratory to a surveillance environment.
A graphical algorithm for fast computation of identity coefficients and generalized kinship coefficients
Authors: Mark Abney
Venue: Bioinformatics (2009)

Summary: Computing the probability of identity by descent sharing among n genes given only the pedigree of those genes is a computationally challenging problem, if n or the pedigree size is large. Here, I present a novel graphical algorithm for efficiently computing all generalized kinship coefficients for n genes. The graphical description transforms the problem from doing many recursion on the pedigree to doing a single traversal of a structure referred to as the kinship graph. Availability: The algorithm is implemented for n = 4 in the software package IdCoefs at http://home.uchicago.edu/abney/Software.html.

Spectral analysis of the heart sounds for medical diagnosis
Authors: I. Iancu, G. Canureci, E. Iancu, M. Vinatoru
Venue: Proceedings of the 4th WSEAS/IASME international conference on Dynamical systems and control (2008)

Cardiovasculary diseases are affecting a constantly growing number of people. Due to this reason we are continously looking for new ways of investigations. The processing of the heart's audio signals also belong to this category. Heart sound is an acoustic wave generated by the mechanical movement of the heart and blood. The sounds can be divided into normal heart sounds and heart murmurs. Murmurs are abnormal signals that appear over wider ranges of frequency than normal heart sounds. The auscultation is a very effective method in detecting heart diseases. Along this paper the authors present the results of the combined time-frequency analysis for short-time periods applied to cardiac signals useful for diagnosis in medical practice.

Spatiotemporal routing algorithm in opportunistic networks
Authors: Hoang Anh Nguyen, Silvia Giordano
Venue: Proceedings of the 2008 International Symposium on a World of Wireless, Mobile and Multimedia Networks (2008)

We propose a new routing scheme (SpatioTempo) based on modeling the mobility of device carriers in periods and cycles. SpatioTempo exploits both the spatial (context) and the temporal (periodical behavior) characteristics of people to better route and optimize the message retransmissions. The combination with Propicman[1] imparts the strong points of the latter, such as context based routing and routing with zero knowledge.
Meta-circularity and MOP in common Lisp for OWL full
Authors: Seiji Koide, Hideaki Takeda
Venue: Proceedings of the 6th European Lisp Workshop (2009)

We have developed an OWL (Web Ontology Language) Full language processor, SWCLOS, for processing semantic web pages on top of the Common Lisp Object System (CLOS). To implement the OWL Full level of capability, we leveraged the dynamic and reflective features of CLOS. The metamodeling capability of CLOS is utilized to realize the metamodeling capability of Resource Description Framework (RDF) and OWL Full. The native computational model of CLOS is changed into the model of RDF and OWL by using the Meta-Object Protocol (MOP) in CLOS. Although the metamodeling specifications in CLOS are firmly established in the Common Lisp community, the semantics is not yet fully developed, since Common Lisp does not have formal semantics. In this paper, we focus on metamodeling in CLOS. We point out that the architecture of CLOS in the metamodeling is the same as in RDF and clarify the denotational semantics of CLOS in comparison with the RDF semantics.

The singly-linked ring topology for the particle swarm optimization algorithm
Authors: Angel Eduardo Muñoz Zavala, Arturo Hernández Aguirre, Enrique Raúl Villa Diharce
Venue: Proceedings of the 11th Annual conference on Genetic and evolutionary computation (2009)

This paper introduces a new neighborhood structure for Particle Swarm Optimization, called Singly-Linked Ring. The approach proposes a neighborhood whose members share the information at a different rate. The objective is to avoid the premature convergence of the flock and stagnation into local optimal. The approach is applied at a set of global optimization problems commonly used in the literature. The singly-linked structure is compared against the state-of-the-art neighborhoods structures. The proposal is easy to implement, and its results and its convergence performance are better than other structures.
A study of language-action perspective as a theoretical framework for web services
Authors: Karthikeyan Umapathy
Venue:  (2008)

A science of services and its technological component, web services are contingent on appropriate theoretical contributions. This dissertation investigates the appropriateness of language-action framework as a source of theory for web services. Web service supports interoperability among applications independent of its platform, through a set of standards. Current web service efforts are hindered by complexities created by proliferation of standards which are sometimes competing and/or overlapping. These complexities undermine usability of web services, therefore hindering widespread adoption. These complexities can be managed by developing boundaries for each web service aspect and design methodologies tailored towards web services. Language-Action Perspective (LAP) is a candidate theoretical perspective because it follows basic premise of web services, i.e., supporting communication among applications to achieve business goals. The central hypothesis of this dissertation is that the LAP would be an appropriate theoretical framework for web services. This hypothesis is tested through three inter-dependent essays. The first essay investigates whether LAP constructs can describe and explain the web services architecture. Findings from this essay reveal a need for mechanisms to guide web service conversations. The second essay investigates this finding with enterprise integration as its application domain. This essay develops a mechanism for accessing design knowledge with LAP constructs. The outcome is translated into web service conversation specifications. As proof of concept, a research prototype that utilizes LAP based mechanism to generate web service conversation specifications as integration solutions is also developed. The third essay assesses the contribution of LAP constructs for designing effective integration solutions. The contribution of LAP constructs were assessed by designing and carrying out a controlled experiment. The assessment shows that LAP based mechanism produces higher quality integration solutions and reduces designer effort required for developing solutions. Significant contributions from this dissertation include an LAP-inspired reference framework for web services (essay 1), a methodology and software artifact for designing enterprise integration solutions as web service conversation specifications (essay 2), an evaluation of the relative effectiveness of LAP constructs for designing web service solutions (essay 3). Together they test the central hypothesis &ndash; appropriateness of LAP as a theoretical framework for web services.

Authors: Sheikh S. I. Mitu, S. M. Al-Shahrani, U. Johar
Venue: Proceedings of the 8th WSEAS international conference on Electronics, hardware, wireless and optical communication (2009)

Microwave sensors are robust non-contact measurement devices for industrial and vehicular application. Phased array-antenna modules, located in the front-end of the sensor, are often used to enhance the performance of this device. In this paper, a novel 24-GHz microstrip linear array antenna with beam-scanning and signal-amplification properties are presented. The phase shift section is designed using digital and analogue phase control properties, to minimize the requirement of complicated control circuits and large external biasing magnet.
Applied Computational Humor and Prospects for Advertising
Authors: Oliviero Stock, Carlo Strapparava
Venue: Proceeding of the 2006 conference on Rob Milne: A Tribute to a Pioneering AI Scientist, Entrepreneur and Mountaineer (2006)

Humor is an important mechanism for communicating new ideas and change perspectives. On the cognitive side humor has two very important properties: it helps getting and keeping people's attention and it helps remembering. This qualities have made it an ideal tool for advertisement. Clearly, the world of advertisement has a great potential for the adoption of computational humor, if the latter is possible at all. Though humor has been called “AI-complete” some prototypes are able to produce expressions limited in humor typology but meant to work in unrestricted domains. In this paper some such work on computational humor is presented and the applied potential of computational humor for advertisement discussed. The followed approach is based on a number of resources with rather shallow internal representations, but with large coverage, and the design of some specialised reasoners.
Secure outsourced aggregation via one-way chains
Authors: Suman Nath, Haifeng Yu, Haowen Chan
Venue: Proceedings of the 35th SIGMOD international conference on Management of data (2009)

We consider the Outsourced Aggregation model, where sensing services outsource their sensor data collection and aggregation tasks to third-party service providers called aggregators. As aggregators can be untrusted or compromised, it is essential for a sensing service to be able to verify the correctness of aggregation results. This work presents SECOA, a framework with a family of novel and optimally-secure protocols for secure outsourced aggregation. Our framework is based on a unified use of one-way chains. It supports a large and diverse set of aggregate functions, can have multiple hierarchically organized aggregators, can deterministically detect any malicious aggregation behavior without communication with sensors, and incurs a small and workload-independent communication load on sensors. We also present extensive evaluation results to demonstrate the feasibility of our framework.
Efficient physics-based planning: sampling search via non-deterministic tactics and skills
Authors: Stefan Zickler, Manuela Veloso
Venue: Proceedings of The 8th International Conference on Autonomous Agents and Multiagent Systems - Volume 1 (2009)

Motion planning for mobile agents, such as robots, acting in the physical world is a challenging task, which traditionally concerns safe obstacle avoidance. We are interested in physics-based planning beyond collision-free navigation goals, in which the agent also needs to achieve its goals, including purposefully manipulate non-actuated bodies, in environments that contain multiple physically interacting bodies with varying degrees of controllability. Physics-based planning is computationally hard due to the large number of continuous motion actions and to the difficulty in accurately modeling the rich interactions of such controlled, manipulatable, and uncontrolled, potentially adversarial, bodies. We contribute an efficient physics-based planning algorithm that uses the agent's high-level behaviors to reduce its motion action space. We first discuss the general physics-based planning problem. We then introduce Tactics and Skills as a model for infusing goal-driven, higher level behaviors into a randomized motion planner. We present a physics-based state and transition model that employs rigid body simulations to approximate real-world interbody-dynamics. We introduce and compare two variations of our tactics-driven, physics-based planning algorithm, namely Behavioral Kinodynamic Balanced Growth Trees and Behavioral Kinodynamic Rapidly-Exploring Random Trees. We tested our physics-based planners in a variety of rich domains and show results in simulated domains where the agent manipulates an object in a dynamic non-adversarial and adversarial environment, namely in a robot minigolf and robot soccer domain, respectively.

Authors: Takeshi Morita, Noriaki Izumi, Takahira Yamaguchi
Venue: Proceeding of the 2008 conference on Knowledge-Based Software Engineering: Proceedings of the Eighth Joint Conference on Knowledge-Based Software Engineering (2008)

In order to reduce the cost of building domain ontologies manually, in this paper, we propose a method and a tool named DODDLE-OWL for domain ontology construction reusing texts and existing ontologies extracted by an ontology search engine: Swoogle. In the experimental evaluation, we applied the method to a particular field of law and evaluated the acquired ontologies.
Numerical investigation of a PH/PH/1 inventory system with positive service time and shortage
Authors: A. Krishnamoorthy, K. P. Jose, Viswanath C. Narayanan
Venue: Neural, Parallel Scientific Computations (2008)

The aim of this paper is to numerically investigate a PH/PH/1 inventory model with reneging of customers and finite shortage of items. We assume that arrivals occur according to a phase type renewal process. The associated phase type distribution has representation (α, U). The service times are identically and independently distributed random variables having common phase type distribution with representation (β, V). The lead-time is zero. Costumers renege from the system at a constant rate γ. Shortage is permitted and hence shortage cost is finite. We perform the steady state analysis of the inventory model using Matrix analytic method. A suitable cost function is defined and analyzed numerically. The optimal shortage level is numerically evaluated. Some measures of the system performance in the steady state are also derived.
