Inductive Displacement Sensor for Force Measuring in Humanoid Robotic Application: Testing the Invariance on Angular Displacement
Authors: Snezana M. Djuric, Laszlo Nagy, Mirjana Damnjanovic
Venue: Proceedings of the 2009 Third International Conference on Sensor Technologies and Applications (2009)

Abstract— A planar displacement inductive sensor, usable in robotics, is presented in the paper. The sensor is composed of two sensor elements. The first sensor element detects vertical displacement while the second sensor element detects horizontal displacement. Combining information from these two sensor elements, it is possible to determine displacement in a plane. Sensor element is a pair of meander coils. One coil is a fixed coil and has the input while the other coil is short-circuited and moves in x-z plane. The variation of input inductance between coils serves as a measure of displacement. The goal of this paper is to show that the variation of the input inductance is invariant to angular displacement of a moving coil, which is important for implementation of the sensor in humanoid robot’s foot. Calculated results were obtained using a new simulation tool developed in MATLAB.
How to Control Clustering Results? Flexible Clustering Aggregation
Authors: Martin Hahmann, Peter B. Volk, Frank Rosenthal, Dirk Habich, Wolfgang Lehner
Venue: Proceedings of the 8th International Symposium on Intelligent Data Analysis: Advances in Intelligent Data Analysis VIII (2009)

One of the most important and challenging questions in the area of clustering is how to choose the best-fitting algorithm and parameterization to obtain an optimal clustering for the considered data. The clustering aggregation concept tries to bypass this problem by generating a set of separate, heterogeneous partitionings of the same data set, from which an aggregate clustering is derived. As of now, almost every existing aggregation approach combines given crisp clusterings on the basis of pair-wise similarities. In this paper, we regard an input set of soft clusterings and show that it contains additional information that is efficiently useable for the aggregation. Our approach introduces an expansion of mentioned pair-wise similarities, allowing control and adjustment of the aggregation process and its result. Our experiments show that our flexible approach offers adaptive results, improved identification of structures and high useability.

Improved current drivability with back-gate bias for elevated source and drain structured FD-SOI SiGe MOSFET
Authors: Hoon Choi, Kyoho Moon, Chulgu Lee, Il Hwan Cho, Sang Jeen Hong
Venue: Microelectronic Engineering (2009)

Fully depleted (FD) silicon-on-insulator (SOI) MOSFET structure with back-gate bias is suggested for high speed and low power consumption for portable communication application. Ni silicide is demonstrated for improving current drivability for low power consumption by reducing series resistance in the source and drain region. Threshold voltage adjustment is also achieved through applied back-gate bias. For the formation of the buried back-gate, the selection of impurity type as well as its doping concentration is controlled. Employing back-gate bias for FD-SOI NMOSFET, improved current drivability with variable threshold voltage is achieved. Short channel devices are fabricated and its electrical characteristics are obtained under various conditions.

Venue: Proceedings of the 8th international conference on International conference for the learning sciences - Volume 3 (2008)

Four research projects used Second Life™, a 3D virtual-world platform, to investigate aspects of technology-enhanced STEM education. These European and USA studies, which differ in their pedagogical-philosophy commitments, theoretical frameworks, methodologies, and target content, critically examine a range of cognitive, affective, technical, and social factors pertaining to the prospects of students' and teachers' successful engagement with immersive microworlds. Specifically, each project describes students' successes and challenges in creating complex virtual artifacts and collaborating in real time with peers and the broader community. The design-based research studies of mathematical and computational literacy present sample student artifacts and discuss the learning they evidence. Collectively, we posit that overcoming the following obstacles could make virtual worlds both effective and exciting learning environments: professional development (technical skill, affective disposition), collaboration with school systems (logistics of access, allocation of resources), alignment with targeted content (harnessing students' creative divergence), and initial learning curves (issues of teacher-to-student ratio).

A Generic Method of Line Matching for Central Imaging Systems under Short-Baseline Motion
Authors: Saleh Mosaddegh, David Fofi, Pascal Vasseur
Venue: Proceedings of the 15th International Conference on Image Analysis and Processing (2009)

Line matching across images taken by a central imaging system (perspective or catadioptric) with focus on short baseline motion of the system is proposed. The relationship between images of lines on unitary sphere is studied and a simple algorithm for matching lines are proposed assuming the rotation of the system is known apriori or it can be estimated from some correspondences in two views. Two methods are discussed for retrieving R in the case it is not known apriori. Experimental results on both synthetic and real images are also presented.
Parallel Skeletons for Variable-Length Lists in SkeTo Skeleton Library
Authors: Haruto Tanno, Hideya Iwasaki
Venue: Proceedings of the 15th International Euro-Par Conference on Parallel Processing (2009)

Skeletal parallel programming is a promising solution to simplify parallel programming. The approach involves providing generic and recurring data structures like lists and parallel computation patterns as skeletons that conceal parallel behaviors. However, when we focus on lists, which are usually implemented as one-dimensional arrays, their length is restricted and fixed in existing data parallel skeleton libraries. Due to this restriction, many problems cannot be coded using parallel skeletons. To resolve this problem, this paper proposes parallel skeletons for lists of variable lengths and their implementation within a parallel skeleton library called SkeTo. The proposed skeletons enable us to solve a wide range of problems including those of twin primes, Knight's tour, and Mandelbrot set calculations with SkeTo. We tested and confirmed the efficiency of our implementation of variable-length lists through various experiments.

This paper presents two prototypes designed in order to enable the automatic adjustment of audio output on mobile devices. One is directed to communication scenarios and the other to media control scenarios. The user centered methodology employed on the design of these prototypes involved 26 users and is also presented here. Once the prototypes were implemented, a usability study was conducted. This study involved 6 users that included our prototypes on their day-to-day lives during a two-week period. The results of the studies are presented and discussed on this paper, providing guidelines for the development of audio output adjustment algorithms and future manufacturing of mobile devices.

Authors: Junfeng He, Hui Wang, Ningwu He, Zhigang Sun, Zhenghu Gong
Venue: Proceedings of the 8th International Symposium on Advanced Parallel Processing Technologies (2009)

Existing distributed content delivery systems like P2P applications may provide significant benefits for content providers and end users. However, they just shifted the considerable cost and burden to Internet Service Providers (ISPs) and well-behaved end users. In P2P applications, the amount of data served by each ISP and payment of many costly transit links are increasing, but the corresponding service revenue from the peer-hosted data services provided doesn't return. In this paper, we present a novel Edge-to-Edge Data Service Model (E2EDSM) which aims to avoid transferring redundant data over the costly core transit links as well as improving the transmission efficiency of mass streaming media. E2EDSM describes a new way for ISP to take part in the processing of content distribution and makes an effort to achieve a winwin goal. Experimental results based on simulation show that E2EDSM achieves better network performance.

Application of Multifactor Conditional CAPM Model in the Evaluation of Mutual Fund Performance
Authors: Ning Xu, Zhi-xin Liu
Venue: Proceedings of the 2009 First International Workshop on Database Technology and Applications (2009)

We explore the added value of introducing extra variables such as size, book to market, momentum. In addition to that we evaluate the use of introducing time-variation in betas and alpha. The search for the most suitable model to measure mutual fund performance will be addressed along two lines. First, we are interested in the statistical significance of adding more factors to the single factor model. Second, we focus on the economic importance of more elaborate model specification.The result is that unconditional CAPM is inferior than the conditional CAPM. The four factor conditional CAPM which include the momentum can best interpret the mutual fund performance.
Irregular Grid Quorum Based Location Management for Wireless Sensor Network
Authors: Yi Li, Dongliang Xie, Canfeng Chen, Jian Ma
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 01 (2009)

Location service provides position of mobile destination to source node so that position based routing can be applied. Several quorum-based location services have been proposed. These location service protocols suffer from complex structure with high overhead, or host location foreknowledge, and difficulty in quorum construction. To overcome those deficiencies, we propose a novel quorum-based location service. In the proposed scheme, location databases are stored in the network nodes themselves, which form a self-organizing virtual backbone network. Quorum system is constructed on the virtual backbone network in conformity to irregular grid rule. Every mobile node will notify its location update information to irregular grid quorum system so that other hosts can obtain the mobile node location through irregular grid quorum system. The simulation results show that our proposed location service leads to high success rate, appropriate quorum size and good load.
Assessing the Impact of Individual Attitude towards Otherness on the Structure of Urban Residential Space: A Multi-actor Model
Authors: André Ourednik
Venue: Proceedings of the International Conference on Computational Science and Its Applications: Part I (2009)

One of the main challenges of today's analytical geography is the back-linking of observed phenomena to individual actions, as not determined by individuals' structural situation in a one-goal society but by their very choice of spatial goals, i.e. by what shall be called individuals' actor-dimension. In this paper we present an actor-based model of urban residential mobility. Results show that public policies in urban development must take into account and act on this actor-dimension if they are not to obtain effects opposite to their aims.
A Wireless Sensor Networks Based on Multi-angle Trust of Node
Authors: Dong Hui-hui, Guo Ya-jun, Yu Zhong-qiang, Chen Hao
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 01 (2009)

Facing the security threats and the energy shortage, a multi-angle trust mechanism for nodes in Wireless Sensor Networks was proposed, which extended the previous trust model only base on communication trust. With adding the sensing data and the node's energy in the factors of trust assessment, and new trust models to calculate the trust values of the sensed data and the node's energy, a more reliable wireless sensor networks could be established. Simulation experiment results show that, one model only based on communication trust is not enough to decide on the trustworthiness of a node. Hence we need to develop new techniques to combine the communication trust, data trust and energy trust into a unite trust.

Authors: Satoshi Suzuki, Takemi Matsui, Yusuke Sakaguchi, Kazuhiro Ando, Nobuyuki Nishiuchi, Toshimasa Yamazaki, Shin'Ichi Fukuzumi
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part I: New Trends (2009)

The present study aimed to investigate this tripartite relationship, regarding MRCP as a physiological index, ballistic movement as an index of operation and accuracy of the task performance. Experiments were conducted 'reaching' task; the subject touches the target appears 300 pixels away from the start point in a vertical direction on the touch sensitive screen with the forefinger. During experiments, EEG, EMG as trigger, image by high-speed camera and the efficiency of task were acquired. As a result, significant differences between the high and poor performance groups were clear on the NS in MRCP acquired from Fz(p < 0.05), Cz (p < 0.05) and Pz (p < 0.05). Furthermore, the difference was confirmed on the duration of ballistic movement. Based on our findings, we attempted to extract MRCP rapidly and automatically without using signal averaging and discuss whether it is possible to estimate accuracy just before the motion is executed.
The Depression of Noise in AE Signals Based on sym8 Wavelet Analysis
Authors: Ning Yang, Xiao-qing Yuan, Yi-kai Shi, Jiang-hai Zhao
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 01 (2009)

To improve the signal-to-noise ratio of the fiber-optic Fabry-Perot acoustic emission sensors, the depression of noise in acoustic emission signals based on sym8 wavelet analysis is introduced. In the process of denoising the signal inspected by fiber-optic Fabry-Perot acoustic emission sensors, most noise of acoustic emission signals is eliminated by using the global soft-threshold filtering. Through analyzing and comparing figures of acoustic emission signals, the Sym8 wavelet of Sym wavelet series and the ‘Minimaxi’ of threshold selection rules are selected and used to denoise the inspection signal. Test results show that acoustic emission signals can be denoised effectively and discernment to the AE signal is greatly improved by selecting basic wavelet, resolving level and de-noising threshold. Thus the Wavelet soft-threshold filtering is an ideal denoising means for acoustic emission signals.
A Study on Quantitative Radar Rainfall Measurements by the Method of Set-pair Analysis
Authors: Luo Peng, Song Xingyuan, Tian Wenwen
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 02 (2009)

This paper introduces the basic principles of Set-pair Analysis ,and presents a method of applying Set-pair Analysis in determining the two parameters of Z ~ I relationship of radar rainfall measurement. This method is then applied in the Bailianhe catchment. After a comparative study between the Set-pair Analysis and the traditional method of CTF, a conclusion is made that ,compared with the traditional method of CTF, the parameters selected by Set-pair Analysis can produce better rainfall results. It can not only improve the precision of the total accumulated rainfall, but also decrease the bad effect that the irrational radar reflectivity and actual measured rainfall data pairs brought to parametric optimization. At the same time, it improves the fitting precision of the rational data, which consequently improves the rationality of the two parameters.
An integrated reasoning approach to moral decision-making
Authors: Morteza Dehghani, Emmett Tomai, Ken Forbus, Matthew Klenk
Venue: Proceedings of the 23rd national conference on Artificial intelligence - Volume 3 (2008)

We present a computational model, MoralDM, which integrates several AI techniques in order to model recent psychological findings on moral decision-making. Current theories of moral decision-making extend beyond pure utilitarian models by relying on contextual factors that vary with culture. MoralDM uses a natural language system to produce formal representations from psychological stimuli, to reduce tailorability. The impacts of secular versus sacred values are modeled via qualitative reasoning, using an order of magnitude representation. MoralDM uses a combination of first-principles reasoning and analogical reasoning to determine consequences and utilities when making moral judgments. We describe how MoralDM works and show that it can model psychological results and improve its performance via accumulating examples.
Archetype-based design: Sensor network programming for application experts, not just programming experts
Authors: Lan S. Bai, Robert P. Dick, Peter A. Dinda
Venue: Proceedings of the 2009 International Conference on Information Processing in Sensor Networks (2009)

Sensor network application experts such as biologists, geologists, and environmental engineers generally have little experience with, and little patience for, general-purpose and often low-level sensor network programming languages. We believe sensor network languages should be designed for application experts, who may not be expert programmers. To further that goal, we propose the concepts of sensor network application archetypes, archetype-specific languages, and archetype templates. Our work makes the following contributions. (1) We have examined a wide range of wireless sensor networks to develop a taxonomy of seven archetypes. This taxonomy permits the design of compact languages that are appropriate for novice programmers. (2) We developed a language (named WASP) and its associated compiler for a commonly encountered archetype. (3) We conducted user studies to evaluate the suitability of WASP and several alternatives for novice programmers. To the best of our knowledge, this 56-hour 28-user study is the first to evaluate a broad range of sensor network languages (TinyScript, Tiny-SQL, SwissQM, and TinyTemplate). On average, users of other languages successfully implemented their assigned applications 30.6% of the time. Among the successful completions, the average development time was 21.7 minutes. Users of WASP had an average success rate of 80.6%, and an average development time of 12.1 minutes (an improvement of 44.4%).

Authors: E. V. Akindinova, V. E. Chernov, I. Yu, I. Yu Kretinin, B. A. Zon
Venue: Journal of Computational Methods in Sciences and Engineering (2009)

The Green function in the quantum defect theory provides an exact account for the high-excited and continuum electronic states. We modify it by taking into account the ground and low-excited states using their wavefunctions calculated ab initio. As an application we present simple and efficient semi-analytical method for calculation of dynamic polarizabilities of nonpolar molecules. The method is applied to alkali dimers Li$_{2}$, Na$_{2}$ and Rb$_{2}$. The result of benchmark calculation (H$_{2}$ molecule) are in good agreement with experimental data; the accuracy achieved is comparable with that of ab initio calculations. We also calculate Verdet constants of the above molecules in Becquerel approximation.
