Authors: Jhin-Fang Huang, Jiun-Yu Wen, Jian-Quan Chen
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 01 (2009)

An UWB dipole antenna comprising of an arbitrary notched band function to prevent ISM band from interference is presented. The proposed dipole antenna demonstrates the UWB operation with an adjustable notched band and is designed on a commercial substrate FR4 having a thickness of 1.6 mm and 4.4 permittivity. Experimental results verify that the proposed antenna achieves a bandwidth covering from 3.1 to 10.6 GHz with VSWR below 2 including the WLAN band notched at the vicinity of 5 GHz, such as the 5.2 GHz band (5150–5350 MHz) and 5.8 GHz band (5725–5875 MHz). The band gain is about 4 dB and sharply decreases about 8 dB to -4 dB for the notched band. This design method offers impressive gain characteristics and can be applied to other frequency bands of interest.
Isolation Forest

Venue: Proceedings of the 2008 Eighth IEEE International Conference on Data Mining (2008)

Most existing model-based approaches to anomaly detection construct a profile of normal instances, then identify instances that do not conform to the normal profile as anomalies. This paper proposes a fundamentally different model-based method that explicitly isolates anomalies instead of profiles normal points. To our best knowledge, the concept of isolation has not been explored in current literature. The use of isolation enables the proposed method, iForest, to exploit sub-sampling to an extent that is not feasible in existing methods, creating an algorithm which has a linear time complexity with a low constant and a low memory requirement. Our empirical evaluation shows that iForest performs favourably to ORCA, a near-linear time complexity distance-based method, LOF and Random Forests in terms of AUC and processing time, and especially in large data sets. iForest also works well in high dimensional problems which have a large number of irrelevant attributes, and in situations where training set does not contain any anomalies.

Authors: Fan Wang, Li Zhou
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

Product Data Management (PDM) system enables the management of the entire product lifecycle and related information about its design, its manufacturing and its in-service. The interest of using the object-oriented approach for modeling, specifying and implementing PDM systems is detailed. Then an implementation method is proposed in order to clarify the instantiation of UML diagrams into database entities. Finally the system is implemented on J2EE platform. The used UML diagrams for the modeling and integration of product, process, and resource data is detailed in order to argue the interest of an object-oriented approach in such kind of PDM implementation.

Ambient Assisted Living (AAL) aims at supporting elderly people in their daily lives, allowing them to grow old at home. In order to provide easy remote control over the rapidly growing number of assistance services from anywhere in the apartment, many AAL environments offer a universal control device. However, the problem of structuring the numerous services for intuitive usage has not been solved satisfactorily yet. This paper introduces a spatial metaphor for universal control devices to structure available services based on the elderly person's own apartment. We carried out a study with 18 younger elderly people using a prototype to evaluate the appropriateness and acceptance of this metaphor. The results included in this paper show that this apartment metaphor is appropriate and accepted by this main target group of AAL.
Tacit Suggestions Extraction Process for Consumer-Oriented Services
Authors: Marta Cimitile, Fabrizio Maria Maggi, Gemma Mastelloni, Giuseppe Visaggio
Venue: Proceedings of the 2009 Third International Conference on Digital Society (2009)

The knowledge deriving from the interactions between organizations offering a service/product and their users can be used to perceive new ideas for service/product improvement. Whenever customers communicate with an organization, unconsciously they give some improvement suggestions that can be extracted through storing, analysis and treatment of their requests, comments and observations. All this induces research studies towards an investigation of tacit suggestions extraction techniques, tools and processes. In this work a framework based on the use of a CRM and a tacit suggestions extraction process is proposed. The framework is applied to an E-Learning context in order to extract new suggestions for the E-Learning services improvement.

Authors: Jia Hong Zhang, Xiong Tinggang, Xiangyan Fang
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 03 (2009)

This paper describes a hardware implementation of modular multiplication coprocessor for both RSA and ECC Cryptosystems. Using a self-improvement Montgomery modular multiplication algorithm, the coprocessor completes a modular multiplication with less clock cycles under the equivalent circumstance of the other designs. This modular multiplier can deal with variable operand lengths, from 128 to 2048. When adopting 64 bits multiplier, it can work at the frequency of 100MHz targeted to Virtex II XC2V250, and executes 256 bits EC point multiplication, with throughput 172k bit/s and 1024 bits RSA decryption (using CRT), with throughput 483k bit/s.
The Aide Diagnosis of Cardiac Heart Diseases Using a Deoxyribonucleic Acid Based Backpropagation Neural Network
Authors: Li Shi, Zhizhong Wang, Lijia Wang, Jinying Zhang
Venue: International Journal of Distributed Sensor Networks (2009)

In this paper, a novel diagnostic scheme of cardiac heart diseases is presented using a Deoxyribonucleic Acid (DNA)-based BP(DNA-BP) Neural Network by distinguishing the shapes of ST segments automatically. First, wavelet transform is applied to extract the ST segments by identifying the characteristic points in the ECG. ECG signals are decomposed by aTrous Algorithm using dyadic spline wavelets. The relationship between the feature points of ECG signals and the modulus maximum pairs of the signals' wavelet transform is established, and the R-wave and ST segment's fiducial points are extracted at different wavelet scales. Second, in order to overcome the disadvantages of the BP neural network, a DNA optimization method is adopted to optimize the original weights and bias of a BP neural network. The BP algorithm is used to find the most optimal values of the weights and bias of the BP network. At last the effectiveness of the proposed aided diagnostic scheme is demonstrated via the experiments which the data are from the clinical study and MIT/BIH ECG data base. In order to validate the advantages of the DNA-based BP (DNA-BP) network and determine the best application conditions of the network, two types of experiments were conducted. In each experiment, 30 samples were selected as the training data and testing data respectively. In the first type of experiments, the data were obtained from the ECG of different people. While in the second type of experiments, the data were obtained from the ECG of one person at different times. The same data and the conditions were used in both BP and GA-based BP (GA-BP) networks to illustrate the advantages of the proposed DNA-based BP network. The experiment results illustrate that the proposed DNA-based BP network overcomes the limitation of the sloping method in identifying straight line ST segments and the limitation of function fitting method in fitting accuracy. It also surmounts the disadvantages of a BP network in terms of the local minimum, slow convergence, and the shortcomings of GA-BP in terms of its limitation in algorithm coding and evolution ways. In conclusion, the neural network is used to supply an invaluable aid for physicians to diagnose cardiac heart diseases and myocardial infarction.

Authors: X. Z. Gao, S. J. Ovaska, X. Wang
Venue: Neural Computing and Applications (2009)

In this study, the linguistic information feed-back-based dynamical fuzzy system (LIFBDFS) proposed earlier by the authors is first introduced. The principles of &#x03b1;-level sets and backpropagation through time approach are also briefly discussed. We next employ these two methods to derive an explicit learning algorithm for the feedback parameters of the LIFBDFS. With this training algorithm, our LIFBDFS indeed becomes a potential candidate in solving real-time modeling and prediction problems.
Comparison of intelligent systems in detecting a child's mathematical gift
Authors: Margita Pavlekovic, Marijana Zekic-Susac, Ivana Djurdjevic
Venue: Computers Education (2009)

This paper compares the efficiency of two intelligent methods: expert systems and neural networks, in detecting children's mathematical gift at the fourth grade of elementary school. The input space for the expert system and the neural network model consisted of 60 variables describing five basic components of a child's mathematical gift identified in previous research. The expert system estimated a child's gift based on heuristically defined logic rules, while the scientifically confirmed psychological evaluation of gift based on Raven's standard progressive matrices was used at the output of neural network models. Three neural network algorithms were tested on a Croatian dataset. The results show that both the expert system and the neural network recognize more pupils as mathematically gifted than teachers do. The expert system produces the highest average hit rate, although the highest accuracy in classifying gifted children is obtained by the radial basis neural network algorithm, which also yields lower type II error. Due to the ability of expert systems to explain the result, it can be suggested that both the expert system and the neural network model have potential to serve as effective intelligent decision support tools in detecting mathematical gift in early stage, therefore enabling its further development.

It shows that the grey system model is feasible; the improved full data GM (1, 1) model can be used for long-term forecasting and is more accuracy.
A Behavioral Synthesis Method with Special Functional Units
Authors: Tsuyoshi Sadakata, Yusuke Matsunaga
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

This paper proposes a novel Behavioral Synthesis method that tries to reduce the number of clock cycles under clock cycle time and total functional unit area constraints using special functional units efficiently. Special functional units are designed to have shorter delay and/or smaller area than the cascaded basic functional units for specific operation patterns. For example, a Multiply-Accumulator is one of them. However, special functional units may have less flexibility for resource sharing because intermediate operation results may not be able to be obtained. Hence, almost all conventional methods can not handle special functional units efficiently for the reduction of clock cycles in practical time, especially under a tight area constraint. The proposed method makes it possible to solve module selection, scheduling, and functional unit allocation problems using special functional units in practical time with some heuristics. Experimental results show that the proposed method has achieved maximally 33% reduction of the cycles for a small application and 14% reduction for a realistic application in practical time.

Authors: Emily Navarro, André van der Hoek
Venue: Proceedings of the 40th ACM technical symposium on Computer science education (2009)

In this paper, we describe a multi-site evaluation of SimSE, an educational software engineering simulation game. This study was designed to build on our previous experience of evaluating SimSE in courses and controlled lab settings at UC Irvine, in order to validate our findings and discover any factors that come into play when SimSE is used in other institutions. The study consisted of three different universities using SimSE in their respective courses and reporting the results to us. The results confirmed several of our previous findings, as well as highlighted a number of critical considerations that must be taken into account when using SimSE in a course.
Validation Aspects of Automatic Service Composition
Authors: Mazen Malek Shiaa, Jan Ove Fladmark
Venue: Service-Oriented Computing - ICSOC 2007 Workshops: ICSOC 2007, International Workshops, Vienna, Austria, September 17, 2007, Revised Selected Papers (2009)

The paper studies the validation aspects of service composition, in particular the goal-based aspects. By service composition we are targeting the automated composition of service components that fit certain demands from a portfolio of available service components --- typically referred to as service repository. It is arguable that the use of ontologies and semantic annotations of service components constitute an intelligent way to enhance service discovery and service composition mechanisms. However, validating the intention of a certain composition --- goals --- and verifying its requirements is still a topic for research development. This paper presents a simple approach to validate service compositions based on goal annotations. The effectiveness of this approach is highlighted through a simplified service example.
Comparison of OMA BCAST 1.0 service guide with DVB-IPDC phase 1 ESG over DVB-H
Authors: Hsin-Ta Chiao
Venue: Proceedings of the International Conference on Mobile Technology, Applications, and Systems (2008)

DVB-H is a European transmission standard for mobile multimedia broadcasting, and planed to be deployed not only in Europe, but also in several Asian and African countries. Since DVB-H is mainly designed for delivering IP packets over terrestrial broadcast networks, other service layer specifications over DVB-H are required for supporting IP-based service applications. Currently, two service layer specifications are available over DVB-H, and they are the OMA BCAST 1.0 specification and the DVB-IPDC phase 1 specification. In fact, the data-plane protocols of the two specifications for delivering both AV streams and files are almost the same, and could be easily harmonized. However, the control-plane protocols of the two specifications are of more difference, such as the service description and discovery frameworks, and the service and content protection frameworks. In this paper, we compare the service description and discovery frameworks of the two specifications -- the OMA BCAST Service Guide and the DVBIPDC ESG (Electronic Service Guide), and highlight similarities and differences that are worth noting.

Effect of hydrogenation on the cathodoluminescence properties of ZnO single crystals
Authors: B. Dierre, X. L. Yuan, T. Sekiguchi
Venue: Microelectronics Journal (2009)

The effect of hydrogenation on the intensity evolution of ZnO single crystal under electron beam irradiation was investigated by cathodoluminescence (CL). Without hydrogenation, the ultraviolet (UV) emission for O-face decreases exponentially and reaches a constant value with e-beam irradiation, while that for Zn-face once increases and then decreases. The hydrogenation significantly increases the UV emission for both faces. On the other hand, the amplitude of the decreasing component of the O-face becomes larger, while the increasing component is not affected. These results suggest that hydrogen only affects the decreasing component of the UV intensity evolution.
Designing a Line-clipping Algorithm by Categorizing Line Dynamically and Using Intersection Point Method
Authors: Md. Mafijul Islam Bhuiyan
Venue: Proceedings of the 2009 International Conference on Electronic Computer Technology (2009)

This algorithm supports line clipping against a rectangular window with edges parallel to the screen. The algorithm combines different categories of lines for solutions. Each category of line is solved with the best way it has. Here intersection point method is used to get the solution of some categories of lines. This algorithm reduces implicit area codes, line ends comparison, redundant calculations, explicit calculation reusing. Here, the region of Line in a rectangle window is not considered for the selection of category rather the characteristics of Lines according to their slope and relationship between the Line and boundary region of the window is considered for selecting categories. It is faster than existing algorithms such as Cohen-Sutherland, Liang-Barsky & Cyrus-Beck.
