Let's Get Physical: Models and Methods for Real-World Security Protocols
Authors: David Basin, Srdjan Capkun, Patrick Schaller, Benedikt Schmidt
Venue: Proceedings of the 22nd International Conference on Theorem Proving in Higher Order Logics (2009)

Traditional security protocols are mainly concerned with key establishment and principal authentication and rely on predistributed keys and properties of cryptographic operators. In contrast, new application areas are emerging that establish and rely on properties of the physical world. Examples include protocols for secure localization, distance bounding, and device pairing.We present a formal model that extends inductive, trace-based approaches in two directions. First, we refine the standard Dolev-Yao model to account for network topology, transmission delays, and node positions. This results in a distributed intruder with restricted, but more realistic, communication capabilities. Second, we develop an abstract message theory that formalizes protocol-independent facts about messages, which hold for all instances. When verifying protocols, we instantiate the abstract message theory, modeling the properties of the cryptographic operators under consideration. We have formalized this model in Isabelle/HOL and used it to verify distance bounding protocols where the concrete message theory includes exclusive-or.
Numerical Checking of C1 for Arbitrary Degree Quadrilateral Subdivision Schemes
Authors: U. H. Augsdörfer, T. J. Cashman, N. A. Dodgson, M. A. Sabin
Venue: Proceedings of the 13th IMA International Conference on Mathematics of Surfaces XIII (2009)

We derive a numerical method to confirm that a subdivision scheme based on quadrilateral meshes is C 1 at the extraordinary points. We base our work on Theorem 5.25 in Peters and Reif's book "Subdivision Surfaces", which expresses it as a condition on the derivatives within the characteristic ring around the EV. This note identifies instead a sufficient condition on the control points in the natural configuration from which the conditions of Theorem 5.25 can be established.
Three Dimensional Monocular Human Motion Analysis in End-Effector Space
Authors: Søren Hauberg, Jerome Lapuyade, Morten Engell-Nørregård, Kenny Erleben, Kim Steenstrup Pedersen
Venue: Proceedings of the 7th International Conference on Energy Minimization Methods in Computer Vision and Pattern Recognition (2009)

In this paper, we present a novel approach to three dimensional human motion estimation from monocular video data. We employ a particle filter to perform the motion estimation. The novelty of the method lies in the choice of state space for the particle filter. Using a non-linear inverse kinematics solver allows us to perform the filtering in end-effector space. This effectively reduces the dimensionality of the state space while still allowing for the estimation of a large set of motions. Preliminary experiments with the strategy show good results compared to a full-pose tracker.

Authors: Li Chuang
Venue: Proceedings of the 2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009) (2009)

Informationazition construction is one of necessary conditions for enterprise to participate in international competition, and finance sale software is the important part of informationazition construction. However there are seldom domestic finance sale softwares supporting the finance sale management of small and middle enterprises (SME). Therefore, the paper designed and developed a set of finance sale software system based on flexibility and diversity of SME. The system consists of four function modules: order form module, agent module, operator module and backup module. In detailed, order form module and agent module can provide service for finance sale, operator module is designed for data security, and backup module is helpful to enhance system robustness in order to minimizes the loss even if system breakdown happens.

Recognizing textual entailment using a subsequence kernel method
Authors: Rui Wang, Günter Neumann
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 1 (2007)

We present a novel approach to recognizing Textual Entailment. Structural features are constructed from abstract tree descriptions, which are automatically extracted from syntactic dependency trees. These features are then applied in a subsequence-kernel-based classifier to learn whether an entailment relation holds between two texts. Our method makes use of machine learning techniques using a limited data set, no external knowledge bases (e.g. WordNet), and no handcrafted inference rules. We achieve an accuracy of 74.5% for text pairs in the Information Extraction and Question Answering task, 63.6% for the RTE-2 test data, and 66.9% for the RET-3 test data.
Automatic domain classification of jurisprudence documents
Authors: Edison Andrade Martins Morais, Ana Paula Laboissière Ambrósio
Venue: Proceedings of the 2008 Euro American Conference on Telematics and Information Systems (2008)

Today, users need pro-active information recovery mechanisms that can rapidly obtain the largest amount of relevant information possible. Several information recovery systems are available, but they still have semantic problems related to document treatment and retrieval. The proposed system uses statistical text-mining techniques to semantically associate documents to domains represented by ontologies, giving a similarity degree (relevance) between the document and the domain. A tool was implemented and tested using Jurisprudence documents from the Court of Justice of the State of Goi&aacute;s. These documents are manually indexed by specialists under predefined categories. A comparison between the results obtained using the tool and the manual indexation was thus possible, permitting an analysis of the tool's efficiency using recall, precision and fall-out indexes.

Research on Coordinate Control Influencing Factors Evaluation among Enterprises of B2B EC
Authors: Liu Weibin
Venue: Proceedings of the 2009 IITA International Conference on Services Science, Management and Engineering (2009)

In the era of network, B2B electronic commerce (EC) has become new bright spot to accelerate economy and trend of future business development gradually and it also becomes one of major reasons to economic gaps between developing countries and developed countries. To develop economy, China must develop B2B EC by its national situation; B2B EC has huge development potential in China. However, there are lacks of research on Chinese B2B EC at present; especially it is lack of research on coordinate control among enterprises in Chinese B2B EC, which hinder the development of B2B EC in China healthily. Therefore, based on anal sizing coordinate control influencing factors among enterprises of B2B EC, the paper evaluates coordinate control influencing factors among enterprises of B2B EC on attribute hierarchical mode based on triangular fuzzy number, which is advantage to the quality and management for coordinate control among enterprises if B2B EC; finally, the paper suggest the lack of the research and the further research orientation.
Some Pitfalls for Developing Enculturated Conversational Agents
Authors: Matthias Rehm, Elisabeth André, Yukiko Nakano
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

A review of current agent-based systems exemplifies that a Western perspective is predominant in the field. But as conversational agents focus on rich multimodal interactive behaviors that underlie face-to-face encounters, it is indispensable to incorporate cultural heuristics of such behaviors into the system. In this paper we examine some of the pitfalls that arise in developing such systems.
A Teaching Path for Java Object Oriented Programming
Authors: Su Jian, Weng Wenyong, Wang Zebing
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 03 (2009)

A teaching path for Java programming is discussed in this paper. This path is specially designed for students who have already learned C language and begin to learn Java object oriented programming. Along this path, the concepts and principles of object oriented programming will be taught to students step by step. The students can learn the specifications of the Java language as well as the underlying ideas of object oriented programming. The students will gradually break through the obstacles between the procedure oriented programming and the object oriented programming.
On Ladner's Result for a Class of Real Machines with Restricted Use of Constants
Authors: Klaus Meer
Venue: Proceedings of the 5th Conference on Computability in Europe: Mathematical Theory and Computational Practice (2009)

We study the question whether there are analogues of Ladner's result in the computational model of Blum, Shub and Smale. It is known that in the complex and the additive BSS model a pure analogue holds, i.e. there are non-complete problems in NP ¿ P assuming NP ¿ P. In the (full) real number model only a non-uniform version is known. We define a new variant which seems relatively close to the full real number model. In this variant inputs can be treated as in the full model whereas real machine constants can be used in a restricted way only. Our main result shows that in this restricted model Ladner's result holds. Our techniques analyze a class P/const that has been known previously to be crucial for this kind of results. By topological arguments relying on the polyhedral structure of certain sets of machine constants we show that this class coincides with the new restricted version of ${\rm P}_{\mathbb R},$ thus implying Ladner's result.
Computation and the Periodic Table
Authors: John Baez
Venue: Proceedings of the 2009 24th Annual IEEE Symposium on Logic In Computer Science (2009)

In physics, Feynman diagrams are used to reason about quantum processes. Similar diagrams can also be used to reason about logic, where they represent proofs, and computation, where they represent programs. With the rise of topological quantum field theory and quantum computation, it became clear that diagrammatic reasoning takes advantage of an extensive network of interlocking analogies between physics, topology, logic and computation. These analogies can be made precise using the formalism of symmetric monoidal closed categories. But symmetric monoidal categories are just the n=1, k=3 entry of a hypothesized "periodic table" of k-tuply monoidal n-categories. This raises the question of how these analogies extend. An important clue comes from the way symmetric monoidal closed 2-categories describe rewrite rules in the lambda calculus and multiplicative intuitionistic linear logic.

On the Importance of Teaching Methods and Teacher's Devotion in Education
Authors: Jin Shengji, Yu Hongmei, Sun Yimin
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 01 (2009)

Quality education is an important strategy in our nation's education. Teachers, especially college and university teachers, are the main force of quality education. Thus, college and university teachers have to alter their teaching notion and teaching methods, establish new teaching ideology, play their own role and fulfil their own task. Through powerful teaching reform, we should focus on educating and improve teaching quality and effect. Teaching is a method while educating is an aim.
The Wavelet Transform in the Acoustic Emission Signal Feature Extraction of the Rubbing Fault
Authors: Jin Zhihao, Wang Dan, Jin Wen, Wen Bangchun
Venue: Proceedings of the 2009 First International Workshop on Database Technology and Applications (2009)

The rubbing fault of a rotary machine was simulated with a rubbing-block made of 0Cr18Ni9 steel at the rate of 310 r.p.m. The acoustic emission signals were sampled for the case with rubbing-block and the case without rubbing-block respectively. The feature extraction of acoustic emission signals was studied by means of db10 function of the wavelet transform and the wavelet energy. It is shown that there are 3 kinds of waveforms for the signals from the experiment with a rubbing block, the feature frequency ranges of the rotor rubbing are about 830-920 KHZ at d1 level and about 235-385 KHZ at d3 level, and the energy concentrates on the decomposed signals at d2 and d3 levels for the case with rotor rubbing. The energy ratio feature makes the recognition of the rotor rubbing fault easier.
German particle verbs and pleonastic prepositions
Authors: Ines Rehbein, Josef van Genabith
Venue: Proceedings of the Third ACL-SIGSEM Workshop on Prepositions (2006)

This paper discusses the behaviour of German particle verbs formed by two-way prepositions in combination with pleonastic PPs including the verb particle as a preposition. These particle verbs have a characteristic feature: some of them license directional prepositional phrases in the accusative, some only allow for locative PPs in the dative, and some particle verbs can occur with PPs in the accusative and in the dative. Directional particle verbs together with directional PPs present an additional problem: the particle and the preposition in the PP seem to provide redundant information. The paper gives an overview of the semantic verb classes influencing this phenomenon, based on corpus data, and explains the underlying reasons for the behaviour of the particle verbs. We also show how the restrictions on particle verbs and pleonastic PPs can be expressed in a grammar theory like Lexical Functional Grammar (LFG).

Venue: Proceedings of the ACM SIGKDD Workshop on Human Computation (2009)

Games with A Purpose have successfully harvested information from web users. However, designing games that encourage sustainable and quality data contribution remains a great challenge. Given that many online communities have enjoyed active participation from a loyal following, this research explores how human computation games may benefit from rich interactions inherent in a community. We experimented by implementing two games for commonsense data collection on the leading social community platforms: the Rapport Game on Facebook and the Virtual Pet Game on PTT. In this paper, we present the choices of interaction mode and goal-oriented user model for building a community-based game. The data quality, collection efficiency, player retention, concept diversity, and game stability of both games are analyzed quantitatively from data collected since August/November 2008. Our findings should provide useful suggestions for designing community-based games in the future.
On Computing the Prediction Sum of Squares Statistic in Linear Least Squares Problems with Multiple Parameter or Measurement Sets
Authors: Adrien Bartoli
Venue: International Journal of Computer Vision (2009)

The prediction sum of squares is a useful statistic for comparing different models. It is based on the principle of leave-one-out or ordinary cross-validation, whereby every measurement is considered in turn as a test set, for the model parameters trained on all but the held out measurement. As for linear least squares problems, there is a simple well-known non-iterative formula to compute the prediction sum of squares without having to refit the model as many times as the number of measurements. We extend this formula to cases where the problem has multiple parameter or measurement sets.We report experimental results on the fitting of a warp between two images, for which the number of deformation centres is automatically selected, based on one of the proposed non-iterative formulae.
Graph-Based Analysis of Nasopharyngeal Carcinoma with Bayesian Network Learning Methods
Authors: Alex Aussem, Sergio Rodrigues De Morais, Marilys Corbex, Joël Favrel
Venue: Proceedings of the 7th IAPR-TC-15 International Workshop on Graph-Based Representations in Pattern Recognition (2009)

In this paper, we propose a new graphical framework for extracting the relevant dietary, social and environmental risk factors that are associated with an increased risk of Nasopharyngeal Carcinoma (NPC) based on a case-control epidemiologic study. This framework builds on the use of Bayesian network for representing statistical dependencies between the random variables. BN is directed acyclic graphs that models the joint multivariate probability distribution underlying the data. These graphical models are highly attractive for their ability to describe complex probabilistic interactions between variables. The graph provides a statistical profile of the recruited population and meanwhile help identify a subset of features that are most relevant for probabilistic classification of the NPC. We report experiment results with the NPC case-study data using a novel constraint-based BN structure learning algorithm. We show how the DAG provides an improved comprehension of NPC etiology. Our findings are compared with the risk factors that were suggested in the recent literature in cancerology.
ELLEIPO: a module that computes coordinative ellipsis for language generators that don't
Authors: Karin Harbusch, Gerard Kempen
Venue: Proceedings of the Eleventh Conference of the European Chapter of the Association for Computational Linguistics: Posters & Demonstrations (2006)

Many current sentence generators lack the ability to compute elliptical versions of coordinated clauses in accordance with the rules for Gapping, Forward and Backward Conjunction Reduction, and SGF (Subject Gap in clauses with Finite/Fronted verb). We describe a module (implemented in JAVA, with German and Dutch as target languages) that takes non-elliptical coordinated clauses as input and returns all reduced versions licensed by coordinative ellipsis. It is loosely based on a new psycholinguistic theory of coordinative ellipsis proposed by Kempen. In this theory, coordinative ellipsis is not supposed to result from the application of declarative grammar rules for clause formation but from a procedural component that interacts with the sentence generator and may block the overt expression of certain constituents.

Eventually the result according to design requirements was achieved by modeling and simulating on the switching mode power supply, meantime the deficiency existed was indicated.
Evaluating Critical Strategies for Enterprise Resource Planning Systems Implementation
Authors: Yan Xu, Chung-Hsing Yeh
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 01 (2009)

This paper presents a new evaluation model for the general evaluation problem of the critical strategy which can facilitate a successful enterprise resource planning systems implementation for achieving both global goals of an organization and local objectives of its business units. Based on a cascaded balanced scorecard (BSC) framework, the evaluation model effectively enables the goal alignment across the organizational hierarchy. A linguistic rating method is used to make subjective assessments across the four perspectives of BSC at both the business unit and organization levels. A new algorithm using the concept of multiattribute decision making is developed to obtain an overall contribution rate for each critical strategy. The overall contribution rate of a critical strategy indicates the degree to which the strategy implemented at each business unit contribute to the overall achievement of the organization’s global strategic goals, relative to other critical strategies. Effective planning and management of critical strategies can be facilitated by analyzing and aggregating the overall contribution rate of critical strategies from the aspects of the whole organization, BSC perspectives, and individual business units respectively. An empirical study is conducted to demonstrate the applicability and effectiveness of the evaluation model and the algorithm.
A reinforcement learning algorithm with polynomial interaction complexity for only-costly-observable MDPs
Authors: Roy Fox, Moshe Tennenholtz
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 1 (2007)

An Unobservable MDP (UMDP) is a POMDP in which there are no observations. An Only-Costly-Observable MDP (OCOMDP) is a POMDP which extends an UMDP by allowing a particular costly action which completely observes the state. We introduce UR-MAX, a reinforcement learning algorithm with polynomial interaction complexity for unknown OCOMDPs.
Grassroots open, online, calculus help forums
Authors: Carla Van De Sande
Venue: Proceedings of the 9th international conference on Computer supported collaborative learning - Volume 1 (2009)

The emergence of free, open, online, help forums has transformed tutoring from a private and individual activity into a public and collective endeavor. These forums support asynchronous exchanges between individuals from around the world. Students visit these forums seeking help on specific queries from coursework and receive help from anonymous others. In contrast to help forums designed and supervised by educational researchers, these forums have a grassroots origin. This paper investigates one such calculus help forum for evidence that forum tutors are scaffolding students to contribute to the successful solution of the exercise they posted. An analysis of 200 exchanges on limit and related rates revealed the presence of effective guided problem solving (marked by leading questions and hints), albeit to a limited extent. This work points to the need for discovering ways to augment constructive interactions in popular help forums that have become part of the student learning experience.
