Joint analysis of mixed Poisson and continuous longitudinal data with nonignorable missing values
Authors: Ying Yang, Jian Kang
Venue: Computational Statistics Data Analysis (2010)

Regression models are proposed for joint analysis of Poisson and continuous longitudinal data with nonignorable missing values under fully parametric framework. Our primary interest is to evaluate the influence of the covariates on both Poisson and continuous responses. First, we form the full likelihood with complete data using the multivariate Poisson model and conditional multivariate normal distribution and then construct an ECM algorithm to find the maximum likelihood estimates of the model parameters. Then, under the assumption that the missingness mechanisms for the two responses are independent but nonignorable, namely, dependent on both observed and missing data of the two responses, we choose the logit model for the missingness mechanisms and selection model for the full likelihood. Also, we build two implementations of the Monte Carlo EM algorithm for estimating the parameters in the model. Wald test is employed to test the significance of covariates. Finally, we present the results of the Monte Carlo simulation to evaluate the performance of the proposed methodology and an application to the interstitial cystitis data base (ICDB) cohort study. To the best of our knowledge, our model is the first parametric model for joint analysis of Poisson and continuous longitudinal data with nonignorable missing value.
Towards automatic integration of the business-data layers in enterprise-systems
Authors: Mira Balaban, Lior Limonad
Venue: Journal of Computational Methods in Sciences and Engineering (2009)

Enterprise information systems distinguish the Domain layer that handles the major business logic of an application, from the Data (Persistent) layer that handles storage concerns alone. The integration of these layers is not straightforward since usually the requirement is for partial persistency, i.e., persistency is required only for a subset of the Domain layer classes. Industry tools provide partial help by supporting convenient abstractions on top of concrete database systems. Nevertheless, the developer still has to design the concrete ties between the layers. Full automation can be a great improvement in complex system development, and goes along with the Model Driven Engineering approach. In this paper we introduce a set of independent Data Access Patterns that provide the missing link towards full automation of the Domain-Data layer interaction. Each pattern is a simple refactoring that yields some Data Access layer constructs, and relies on local information in the Domain layer. All patterns are Domain layer transparent, i.e., their application leaves the Domain layer intact. We provide an algorithm for combined pattern application and show its correctness. An implementation of our method is on the way.

CMU-AT: semantic distance and background knowledge for identifying semantic relations
Authors: Alicia Tribble, Scott E. Fahlman
Venue: Proceedings of the 4th International Workshop on Semantic Evaluations (2007)

This system uses a background knowledge base to identify semantic relations between base noun phrases in English text, as evaluated in SemEval 2007, Task 4. Training data for each relation is converted to statements in the Scone Knowledge Representation Language. At testing time a new Scone statement is created for the sentence under scrutiny, and presence or absence of a relation is calculated by comparing the total semantic distance between the new statement and all positive examples to the total distance between the new statement and all negative examples.
Referring expression generation through attribute-based heuristics
Authors: Robert Dale, Jette Viethen
Venue: Proceedings of the 12th European Workshop on Natural Language Generation (2009)

In this paper, we explore a corpus of human-produced referring expressions to see to what extent we can learn the referential behaviour the corpus represents. Despite a wide variation in the way subjects refer across a set of ten stimuli, we demonstrate that component elements of the referring expression generation process appear to generalise across participants to a significant degree. This leads us to propose an alternative way of thinking of referring expression generation, where each attribute in a description is provided by a separate heuristic.
Dynamic dependency parsing
Authors: Michael Daum
Venue: Proceedings of the Workshop on Incremental Parsing: Bringing Engineering and Cognition Together (2004)

The inherent robustness of a system might be an important prerequisite for an incremental parsing model to the effect that grammaticality requirements on full sentences may be suspended or allowed to be violated transiently. However, we present additional means that allow the grammarian to model prefix-analyses by altering a grammar for non-incremental parsing in a controlled way. This is done by introducing underspecified dependency edges that model the expected relation between already seen and yet unseen words during parsing. Thus the basic framework of weighted constraint dependency parsing is extended by the notion of dynamic dependency parsing.

Authors: Jian-Bing Hang, Chen He, He Yun He
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 02 (2009)

A kind of regular LDPC codes is introduced. Its error correct ability is better than Turbo codes' and near to Shannon limit (1.2 dB). The construct of the sparse parity matrix is important. This effects the LDPC codes' error correct ability. In this paper, diagonal method is adopted to construct sparse check matrix of (n,3,6) in approximate lower triangular form by it. This meets the numbers of nonzero elements and randomness. The Belief Propagation algorithm is used in decoding simulation, to this, vector method is proposed which reduces operation time.
AR City Representation System Based on Map Recognition Using Topological Information
Authors: Hideaki Uchiyama, Hideo Saito, Myriam Servières, Guillaume Moreau
Venue: Proceedings of the 3rd International Conference on Virtual and Mixed Reality: Held as Part of HCI International 2009 (2009)

This paper presents a system for overlaying 3D GIS data information such as 3D buildings onto a 2D physical urban map. We propose a map recognition framework by analysis of distribution of local intersections in order to recognize the area of the physical map from a whole map. The retrieval of the geographical area described by the physical map is based on a hashing scheme, which is called LLAH. In the results, we will show some applications augmenting additional information on the map.
Research on Ontology-Based Metadata Model
Authors: Qi Jia, ShouZhong Guo, HaiYong Chen, Nan Li
Venue: Proceedings of the 2009 First International Workshop on Database Technology and Applications (2009)

In many researches, one of major challenges is to archive, access, and analyze various heterogeneous databases containing useful information gathered from a large volume of data. Metadata plays a critical role in database integration, so metadata model is put forward which comprises information of data content. Discussion on information integration solves the problem with manipulating the metadata in term of the semantics. An ontology is an explicit specification of the conceptualization of a domain, which allows various entities represented in different data sources to have the same shared semantic meaning. This paper presents and motivates an extended ontology-based metadata model which represents semantic information about concepts explicitly. The model can be used to solve ambiguities that can arise when applications with heterogeneous databases have to interoperate in order to perform a task.

Authors: Zhu Lei, Chen Xi, Luo Geping, Xu Wenqiang, Liu Yaxuan
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

Taking the Northern Slope of the Tianshan Mountains (NSTM) as the study area, we investigated into the oases LUCC and information entropy change by using RS, GIS and statistical model. The results showed that, (1) Establishing mathematical models of the range, speed and trend index of LUCC, especially the model of LUCC trend and state, the state and trend of oasis LUCC can be deeply researched. Meanwhile, land use system had changed from the quasi-equilibrium state into a equilibrium state. (2) Information entropy change models reflected the orderliness and structure of regional land use system. Land use information entropy has shown a steady downward trend in the past 50 years. Land-use system is increasingly orderly at the same time. However, the orderliness and structure of the land use system in NSTM was still below the national average. (3) LUCC had a great impact on regional land use information entropy change. This paper is a right example for it.
Are PCPs Inherent in Efficient Arguments?
Authors: Guy N. Rothblum, Salil Vadhan
Venue: Proceedings of the 2009 24th Annual IEEE Conference on Computational Complexity (2009)

Starting with Kilian (STOC `92), several works have shown how to use probabilistically checkable proofs (PCPs) and cryptographic primitives such as collision-resistant hashing to construct very efficient argument systems (a.k.a. computationally sound proofs), for example with polylogarithmic communication complexity. Ishai et al. (CCC `07) raised the question of whether PCPs are inherent in efficient arguments, and to what extent. We give evidence that they are, by showing how to convert any argument system whose soundness is reducible to the security of some cryptographic primitive into a PCP system whose efficiency is related to that of the argument system and the reduction (under certain complexity assumptions).

Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 04 (2009)

The Semantic Web aims at defining ways to allow Web information to be used by computers not only for display purposes, but also for interoperability and integration between systems and applications. Much progress has been made in developing ideas and tools to enable the growth of the Semantic Web. As increasing amount of data is published in the form of OWL, copyright protection of OWL data is becoming an important requirement for many applications. In this paper, we investigated the syntax of OWL and proposed some techniques for the digital watermarking based on OWL. Furthermore, we put forward a model to embed watermark into OWL-based ontology. Experimental results also demonstrate that our proposed watermarking methods can be applied to exiting OWL documents easily. The watermarking model is also feasible.

Authors: Zhu Yuhua, Zhen Tong
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 03 (2009)

Grain logistics center is the pivot of a grain logistics system. To define the location of grain logistics distribution center is the key of grain logistics system analysis. In this paper, according to the characteristics and requirements in the selection of the location, a mathematical model applied to the location selection was established on the basis of lowest transportation cost. Genetic Algorithm was then used to solve the model, and the optimal solution of the model was obtained by selecting the encode method and genetic operator correctly, thus verifying the correctness of the model. The instance demonstrates that the algorithm can effectively get the grain logistics center optimal solution.
Dynamical Behavior and Parameter Optimization of a Vibratory System
Authors: Yanlong Zhang, Li Wang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

The primary objectives of the investigation are to analyze the dynamical behavior of a three-degree-of-freedom vibratory system and choose the suitable system parameters to obtain larger impact velocity or larger regions of periodic motions for engineering application. Stability and local bifurcations of one-impact periodic motion are analyzed by using Jacobian matrix of the Poincaré mapping. Global bifurcations are used to optimize the system parameters. Based on theoretical analysis and numerical simulation, some unusual bifurcations are obtained, such as Neimark-Sacker bifurcation including torus doubling, discontinuous period doubling bifurcation including Neimark-Sacker bifurcation, or torus doubling, or grazing singularities. And their routes from periodic motions to chaos are discussed as well. Some methods of obtaining larger impact velocity or larger regions of periodic motions are presented too.

Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

Community education serves as a significant part to construct the lifelong educational system, and as a necessary channel to establish the learning society. Grid technology is proposed to settle the problems of distributed calculating and system resources sharing. The realized function of resources sharing, personalized service, and cooperative support can fully suffice the learners’ need to obtain learning support and cooperative learning in the learning process. This paper analyzes the current development of the community colleges and distance education systems, discusses the integration of sorts of resources of distance educational systems and community education by the use of grid technology, and brings forward an effective approach to set up a virtual community university based on the grid technology.
Quantification of thermoreflectance temperature measurements in high-power semiconductor devices-lasers and laser bars
Authors: K. Pierciński, D. Piercińska, M. Bugajski
Venue: Microelectronics Journal (2009)

In this paper we present results of the analysis of the thermoreflectance (TR) measurements performed on the high-power laser diodes and laser bar emitting at 808nm. TR is a modulation technique relying on periodic facet temperature modulation induced by pulsed current supply of the laser. The periodic temperature change of the laser induces variation of the refractive index and consequently modulates probe beam reflectivity. Spatially resolved TR spectroscopy is applied to measure line-scans and maps of temperature distribution at the laser mirrors and emitter facets in laser bar. However, to get the absolute values of temperatures, TR needs calibration. Different calibration methods, such as @m-Raman spectroscopy and in situ determination of TR coefficient (C"T"R), will be discussed. The knowledge of temperature distribution at laser facets gives insight into thermal processes occurring at devices' facets and consequently leads to the increased reliability and substantially longer lifetimes of such structures.

Authors: Emily Whiting, John Ochsendorf, Frédo Durand
Venue: ACM Transactions on Graphics (TOG) (2009)

We introduce structural feasibility into procedural modeling of buildings. This allows for more realistic structural models that can be interacted with in physical simulations. While existing structural analysis tools focus heavily on providing an analysis of the stress state, our proposed method automatically tunes a set of designated free parameters to obtain forms that are structurally sound.

Modeling Radio Networks
Authors: Calvin Newport, Nancy Lynch
Venue: Proceedings of the 20th International Conference on Concurrency Theory (2009)

We describe a modeling framework and collection of foundational composition results for the study of probabilistic distributed algorithms in synchronous radio networks. Existing results in this setting rely on informal descriptions of the channel behavior and therefore lack easy comparability and are prone to error caused by definition subtleties. Our framework rectifies these issues by providing: (1) a method to precisely describe a radio channel as a probabilistic automaton; (2) a mathematical notion of implementing one channel using another channel, allowing for direct comparisons of channel strengths and a natural decomposition of problems into implementing a more powerful channel and solving the problem on the powerful channel; (3) a mathematical definition of a problem and solving a problem; (4) a pair of composition results that simplify the tasks of proving properties about channel implementation algorithms and combining problems with channel implementations. Our goal is to produce a model streamlined for the needs of the radio network algorithms community.

Authors: Nan Wu, Ji-Xi Gao, Driss Ennaanay, Guillermo F. Mendoza, Sudebilige, Zun-Lan Luo, Dai-Qing Li
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 03 (2009)

In China the current approaches to evaluating the efficacy of the ecosystem service for avoided-reservoir-sedimentation cannot identify the supplier and beneficiary. In addition, the use of the same whole-country coefficient of sediment delivery for different areas can lead to inaccurate results. Based on the integrated Geographic Information System(GIS) software package, ArcGIS9.2, a new model was established to simulate this ecosystem service and its economic value. The model included fabricating the watershed of the study reservoir. The Sediment Delivery Ratio (SDR) and the Universal Soil Loss Equation (USLE) were used to simulate the spatial patterns of the annual sediment yield and sediment retention in watershed. The economic value in this model of the ecosystem service was determined for a fixed number of years. Taking the Ertan reservoir as an example, the results showed that the actual sediment yield was 629.3×104t•a-1 in the watershed. It occupied 12.7% of the actual soil erosion volume. Farmland was the most important source of sediment yield. Its actual sediment yield occupied 62.9% of the total. The region with a higher quantity of sediment yield and sediment retention was around the reservoir. The contribution ratio of the forest to the avoided-reservoir-sedimentation service value was higher than those of the other contributors on a per unit area basis. For the reservoir’s designed operating life, the total value of this service in the watershed was 27529.2×108Yuan.
Trust Transference in Mobile Banking: An Investigation of the Initial Trust
Authors: Chu Shan, Yao-bin Lu
Venue: Proceedings of the 2009 IITA International Conference on Services Science, Management and Engineering (2009)

The objective of this research is to reveal the mechanisms associated with the initial formation of people’s trust in mobile banking and intention to use the service. And this research fills a research gap by focusing on online to mobile trust transfer process, which has received almost no attention. For this, we attempt to understand the effect of three antecedent factors (structural assurance, compatibility and relative advantage) on shaping a customer’s initial trust in mobile banking and usage intention. Furthermore, we investigate the impact of trust in online banking on the initial trust in mobile banking and its antecedents. The study tests hypothesis by using a sample of 313 cell-phone users who have used online banking before. Results show that online trust influence initial trust in mobile banking and all its three antecedent factors, just as proposed. Thus, online-to-mobile trust transfer should be considered when designing multichannel strategies and attracting customers to use mobile banking.
Proceedings of the Workshop on Software Engineering, Testing, and Quality Assurance for Natural Language Processing
Venue: ACL Workshops (2009)

Software engineering is a first-class research topic in computer science, but generally has not been treated as such within the natural language processing community. However, the need for wellengineered NLP components is increasing as NLP begins to show up outside our research community: bioinformatics, the search industry, education applications, etc. In addition, NLP research itself, e.g., when it involves large data sets, often requires a high level of software quality. Simply applying standard software engineering practices to NLP often fails due to the unique characteristics of natural language as an input type. The goals of this workshop include raising awareness of the need for good software engineering practices in NLP, stimulating research on same, and providing a forum for sharing current work in this area.
