Support Method for Improving the Ability of People with Cerebral Palsy to Efficiently Point a Mouse at Objects on a GUI Screen
Authors: Hiromi Nishiguchi
Venue: Proceedings of the 1st International Conference on Human Centered Design: Held as Part of HCI International 2009 (2009)

Many people with cerebral palsy work in social welfare companies as data entry operators etc. Because of spastic reactions and involuntary motion, they find it difficult to use their upper limbs for movement and positioning tasks such as pointing a mouse at an object on a GUI screen. It would be of great benefit to secure the movement distance and the target size which are appropriate for people with cerebral palsy on a GUI screen, so they can perform pointing device operation effectively. However, it is not possible to increase the screen size beyond a certain limit. Therefore, ideal conditions may not be achieved. In such a situation, an effective environment for positioning tasks can be created by controlling the D/C gain, which is calculated by dividing the movement distance of the pointer by that of the input device. This study investigated the effect of changes in the D/C gain on motion time (MT) for pointing tasks and attempted to determine the D/C gain for minimizing the MT. It was found that the D/C gain for minimizing the MT could be obtained by using an appropriate combination of the target distance and target size. Further, the relation between the D/C gain and the positioning time is found to be linear or second-order curvilinear, depending on the target distance and target size.

Mixed-initiative approach to collaboration in the mathematical domain
Authors: Nadya Belov, Joshua Shaffer
Venue: Proceedings of the 20th national conference on Artificial intelligence - Volume 4 (2005)

Using smart-phones for ad-hoc mathematical collaboration poses multiple user interface challenges. In this paper, software agents are used to lessen the cognitive load through automatic line labeling. Researchers in the human-computer interaction community have attempted to alleviate the problem of general usability through user interface engineering conventions (Myers 1994). However, these engineering approaches can be improved upon through the application of mixed-initiative principles.

Authors: Salih Okur, Fahrettin Yakuphanoglu, Mehmet Ozsoz, Pınar Kara Kadayifcilar
Venue: Microelectronic Engineering (2009)

The effect of the thickness and coverage rate of a DNA film on the electrical and interface properties of Au/DNA/n-Si organic-on-inorganic structures has been investigated. The thin film properties of the DNA deposited on n-Si wafer were characterized by atomic force microscopy. The effect of the thickness and coverage rate of the DNA layer was investigated by evaluating electrical parameters, such as the barrier height, ideality factor, series resistance, and interface state density. The thickness and coverage rate of the DNA layer significantly affects the electrical properties of the Au/DNA/n-Si organic-on-inorganic structures. The interface state density properties of the Au/DNA/n-Si diodes were determined by conductance technique. The results show that the interface state density decreases with decrease in both film thickness and coverage rate of the DNA in an acetate buffer, modifying the electronic parameters of the Au/DNA/n-Si diodes.

Authors: Ying Su, Jie Peng, Zhanming Jin
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 01 (2009)

The objective of this paper is to propose a geospatial data quality (G-DQ) Self-Assuring model using an Intelligent Multi-Agent (IMA) technique, which is capable to monitor network status, evaluate G-DQ, generate assuring strategies, and apply it to the disaster management system. To do this, we have employed the IMA algorithm concept based on the advanced artificial intelligence for developing information security models and agent-based evaluation of G-DQ as well as assuring strategy. Our approach differs from others in that a) it is able to analyze G-DQ in quantitative manner, b) it can generate and apply assuring strategies automatically, and c) it supports a coherent design concept for G-DQ Self-Assuring system. Simulation results show that the proposed approach increases the efficiency and results in quality information acquisition.
Separating Trace Mapping and Reactive Simulatability Soundness: The Case of Adaptive Corruption
Authors: Laurent Mazaré, Bogdan Warinschi
Venue: Foundations and Applications of Security Analysis: Joint Workshop on Automated Reasoning for Security Protocol Analysis and Issues in the Theory of Security, ARSPA-WITS 2009, York, UK, March 28-29, 2009, Revised Selected Papers (2009)

Computational soundness is the research direction that aims to translate security guarantees with respect to Dolev-Yao models into guarantees with resepect to the stronger computational models of modern cryptography. There are essentially two different approaches that aim to achieve computational soundness. One approach is based on the so-called trace mapping theorems, and one based on reactive simulatability. In a recent paper, Backes, Dürthmuth, and Küsters have shown that the stronger requirements needed for reactive simulatability-based soundness imply that a trace mapping theorem also holds. It was left as an open problem whether there exists interesting settings where the simulatability framework breaks down but mapping theorems still exist.In this paper we describe one such setting, and thus give a separation between the two frameworks. Specifically, we show that adaptive corruption of symmetric encryption keys (a problematic setting for simulation-based frameworks) can be smoothly treated in a mapping theorem-based soundness framework.A crucial ingredient of our proof, and a result of independent interest, is a new (indistinguishability based) security notion for encryption. The central feature of our definition is that in addition to standard chosen-ciphertext attacks in multi-user settings, it also directly accounts for adaptive corruption of decryption keys. We show that our notion satisfies the intuitively appealing property that it is equivalent to standard security requirements on encryption.
A MAC Protocol for Cooperative Wireless Networks
Authors: Kefei Lu, Xiaodong Cai, Xudong Wang
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

Recently, cooperative communications have been proposed to improve the performance of wireless networks. In this paper, we develop a medium access control (MAC) protocol for cooperative wireless networks, which is ready to be incorporated into IEEE 802.11 networks. In the proposed MAC protocol, when a retransmission is needed, the packet is retransmitted from a cooperating node, that is able to overhear the transmitted signals from the source and decode the information bits correctly, after re-encoding the information bits using a properly chosen error correcting code. To ensure orderly cooperation among multiple cooperating nodes using a minimum signaling overheard, a deterministic backoff scheme is employed to specify the order that the source and cooperating nodes access the channel. Our simulation results demonstrate that node cooperation can increase system throughput and improve network coverage.

Polynomial Operators on Classes of Regular Languages
Authors: Ondřej Klíma, Libor Polák
Venue: Proceedings of the 3rd International Conference on Algebraic Informatics (2009)

We assign to each positive variety $\mathcal V$ and each natural number k the class of all (positive) Boolean combinations of the restricted polynomials, i.e. the languages of the form $L_0a_1 L_1a_2\dots a_\ell L_\ell, \text{ where } \ell\leq k$, a 1,...,a ¿ are letters and L 0,...,L ¿ are languages from the variety $\mathcal V$. For this polynomial operator we give a certain algebraic counterpart which works with identities satisfied by syntactic (ordered) monoids of languages considered. We also characterize the property that a variety of languages is generated by a finite number of languages. We apply our constructions to particular examples of varieties of languages which are crucial for a certain famous open problem concerning concatenation hierarchies.2000 Classification: 68Q45 Formal languages and automata.
A Pulse Design Method to Suppress Narrowband Interference for UWB System
Authors: Yanli Hou, Jiawei Hu, Weimin Hou, Boning Hu
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

UWB(Ultra Wideband) system takes up extremely wide bandwidth, so it interferes with narrowband communication systems each other easily, that influences the system performance. The main approach to the problem is designing pulse waveform for UWB system to make it have notches in narrowband interferences. The paper designed UWB pulse with APSWF (approximate prolate spheroidal wave functions) that is finite in time domain and frequency domain, made generated pulse satisfy the demand of spectrum hole. The experimental results showed that, the designed pulse could avoid the central frequencies of narrowband systems, and suppressed the narrowband interferences, so solved the coexistence of UWB system and narrowband communication systems successfully.
Micro/nanoporous membrane based gas&#x2013;water separation in microchannel
Authors: Xiaoshan Zhu
Venue: Microsystem Technologies (2009)

In this paper, a method coupling micro/nanoporous membranes with microchannels for the gas/water separation in microscale has been demonstrated. The principle of separation is based on the basic properties of membranes&#x2014;wetted micro/nanoporous hydrophilic membranes can block gas due to a large water surface tension in the entrance of micro/nano pores to withstand the gas pressure, while it allows water to permeate with overcoming the flow resistance of pores; in contrast, hydrophobic membranes permit gas to penetrate but prevent water flow. These two kinds of membranes coupled with microchannels in cross-flow mode or dead-end mode can separate gas/water in microscale. The separation in cross-flow mode can achieve relative high water permeate flow rate, while the separation in dead-end mode can completely separate gas/water segments in a single operation step. The membrane-based separation method has low cost, easy integration into microfludics channels, design flexibility with two configuration modes (cross-flow and dead-end).

An Information Roadmap Method for Robotic Sensor Path Planning
Authors: G. Zhang, S. Ferrari, M. Qian
Venue: Journal of Intelligent and Robotic Systems (2009)

A new probabilistic roadmap method is presented for planning the path of a robotic sensor deployed in order to classify multiple fixed targets located in an obstacle-populated workspace. Existing roadmap methods have been successful at planning a robot path for the purpose of moving from an initial to a final configuration in a workspace by a minimum distance. But they are not directly applicable to robots whose primary objective is to gather target information with an on-board sensor. In this paper, a novel information roadmap method is developed in which obstacles, targets, sensor's platform and field-of-view are represented as closed and bounded subsets of an Euclidean workspace. The information roadmap is sampled from a normalized information theoretic function that favors samples with a high expected value of information in configuration space. The method is applied to a landmine classification problem to plan the path of a robotic ground-penetrating radar, based on prior remote measurements and other geospatial data. Experiments show that paths obtained from the information roadmap exhibit a classification efficiency several times higher than that of existing search strategies. Also, the information roadmap can be used to deploy non-overpass capable robots that must avoid targets as well as obstacles.
Robust ending guessing rules with application to Slavonic languages
Authors: Preslav Nakov, Elena Paskaleva
Venue: Proceedings of the 3rd Workshop on RObust Methods in Analysis of Natural Language Data (2004)

The paper studies the automatic extraction of diagnostic word endings for Slavonic languages aimed to determine some grammatical, morphological and semantic properties of the underlying word. In particular, ending guessing rules are being learned from a large morphological dictionary of Bulgarian in order to predict POS, gender, number, article and semantics. A simple exact high accuracy algorithm is developed and compared to an approximate one, which uses a scoring function previously proposed by Mikheev for POS guessing. It is shown how the number of rules of the latter can be reduced by a factor of up to 35, without sacrificing performance. The evaluation demonstrates coverage close to 100%, and precision of 97--99% for the approximate algorithm.

Authors: Bernhard Wunderle, K.-F. Becker, R. Sinning, O. Wittler, R. Schacht, H. Walter, M. Schneider-Ramelow, K. Halser, N. Simper, B. Michel, H. Reichl
Venue: Microsystem Technologies (2009)

In this paper we examine the thermo-mechanical reliability of polymer-encapsulated chip-on-board (COB) assemblies for power applications by simulation and experiment. Thereby the focus is set on the low cycle fatigue failure behaviour of the die-attach material under thermal cycling conditions. As die-attach material different solder materials and Ag-filled thermal adhesives have been used. The encapsulation was performed with a soft silicone-based and hard silica-reinforced epoxy-based material, respectively. An other process variable takes into account die-tilt. The study was carried out as a feasibility analysis in the course of a COB technology development. To this end lifetime models have been employed to correlate crack growth in the, i.e. attach to a computational accumulative failure criterion which allows to consistently describe ad predict quantitatively the lifetime of the assemblies. Thereby a considerable influence of the encapsulation was found. In particular it could be shown that a hard encapsulation largely increases reliability for solder die-attach.
An automated bacterial colony counting and classification system
Authors: Wei-Bang Chen, Chengcui Zhang
Venue: Information Systems Frontiers (2009)

Bacterial colony enumeration is an essential tool for many widely used biomedical assays. However, bacterial colony enumerating is a low throughput, time consuming and labor intensive process since there may exist hundreds or thousands of colonies on a Petri dish, and the counting process is usually manually performed by well-trained technicians. In this paper, we introduce a fully automatic yet cost-effective bacterial colony counter which can not only count but also classify colonies. Our proposed method can recognize chromatic and achromatic images and thus can deal with both color and clear medium. In addition, the proposed method is software-centered and can accept general digital camera images as its input. The counting process includes detecting dish/plate regions, identifying colonies, separating aggregated colonies, and reporting colony counts. In order to differentiate colonies of different species, the proposed counter adopts one-class Support Vector Machine (SVM) with Radial Basis Function (RBF) as the classifier. Our proposed counter demonstrates a promising performance in terms of both precision and recall, and is robust and efficient in terms of labor-and time-savings.
Large linguistically-processed web corpora for multiple languages
Authors: Marco Baroni, Adam Kilgarriff
Venue: Proceedings of the Eleventh Conference of the European Chapter of the Association for Computational Linguistics: Posters & Demonstrations (2006)

The Web contains vast amounts of linguistic data. One key issue for linguists and language technologists is how to access it. Commercial search engines give highly compromised access. An alternative is to crawl the Web ourselves, which also allows us to remove duplicates and near-duplicates, navigational material, and a range of other kinds of non-linguistic matter. We can also tokenize, lemmatise and part-of-speech tag the corpus, and load the data into a corpus query tool which supports sophisticated linguistic queries. We have now done this for German and Italian, with corpus sizes of over 1 billion words in each case. We provide Web access to the corpora in our query tool, the Sketch Engine.
A robust and hybrid deep-linguistic theory applied to large-scale parsing
Authors: Gerold Schneider, James Dowdall, Fabio Rinaldi
Venue: Proceedings of the 3rd Workshop on RObust Methods in Analysis of Natural Language Data (2004)

Modern statistical parsers are robust and quite fast, but their output is relatively shallow when compared to formal grammar parsers. We suggest to extend statistical approaches to a more deep-linguistic analysis while at the same time keeping the speed and low complexity of a statistical parser. The resulting parsing architecture suggested, implemented and evaluated here is highly robust and hybrid on a number of levels, combining statistical and rule-based approaches, constituency and dependency grammar, shallow and deep processing, full and near-full parsing. With its parsing speed of about 300,000 words per hour and state-of-the-art performance the parser is reliable for a number of large-scale applications discussed in the article.
Converting text into agent animations: assigning gestures to text
Authors: Yukiko I. Nakano, Masashi Okamoto, Daisuke Kawahara, Qing Li, Toyoaki Nishida
Venue: Proceedings of HLT-NAACL 2004: Short Papers on XX (2004)

This paper proposes a method for assigning gestures to text based on lexical and syntactic information. First, our empirical study identified lexical and syntactic information strongly correlated with gesture occurrence and suggested that syntactic structure is more useful for judging gesture occurrence than local syntactic cues. Based on the empirical results, we have implemented a system that converts text into an animated agent that gestures and speaks synchronously.

Domain adaptation with structural correspondence learning
Authors: John Blitzer, Ryan McDonald, Fernando Pereira
Venue: Proceedings of the 2006 Conference on Empirical Methods in Natural Language Processing (2006)

Discriminative learning methods are widely used in natural language processing. These methods work best when their training and test data are drawn from the same distribution. For many NLP tasks, however, we are confronted with new domains in which labeled data is scarce or non-existent. In such cases, we seek to adapt existing models from a resource-rich source domain to a resource-poor target domain. We introduce structural correspondence learning to automatically induce correspondences among features from different domains. We test our technique on part of speech tagging and show performance gains for varying amounts of source and target training data, as well as improvements in target domain parsing accuracy using our improved tagger.

Traffic accidents or fires in highway tunnels were increased in the last decade. How to reduce the accidents and its consequent harms? The computer aided emergency management system deployed within the surveillance and control system for highway tunnels, was brought forward. The system integrated functions of other subsystems, and formed a strong comprehensive ability to automatically aid emergency management. The definition about functions of the system was given, and the principles of the system were designed and discussed. Then the methods and technologies applied to realize the system were demonstrated. Finally, the standard architecture of the system was colligated.
