Atmel AVR Microcontroller Primer: Programming and Interfacing, 1st edition
Authors: Steven F. Barrett, Daniel Pack, Mitchell Thornton
Venue:  (2007)

This textbook provides practicing scientists and engineers a primer on the Atmel AVR microcontroller. Our approach is to provide the fundamental skills to quickly get up and operating with this internationally popular microcontroller. The Atmel ATmega16 is used as a representative sample of the AVR line. The knowledge you gain on the ATmega16 can be easily translated to every other microcontroller in the AVR line. We cover the main subsystems aboard the ATmega16, providing a short theory section followed by a description of the related microcontroller subsystem with accompanying hardware and software to exercise the subsytem. In all examples, we use the C programming language. We conclude with a detailed chapter describing how to interface the microcontroller to a wide variety of input and output devices.
Measurement Driven Simulation of Complex Engineering Systems
Authors: Arnoud Visser
Venue:  (2007)

The Dutch polder model recently dubbed a 'success story' by Bill Clinton and Jacques Delors - plays a prominent role in current discussions about possibilities for a new 'capitalism with a social face', and appeals to experts all over the world. Just ten years ago the Swedish sociologist Gran Therborn described the Dutch employment policy as a 'spectacular failure'. The authors single out three policy changes to explain the 'miracle' that has taken place since then. The 'Dutch miracle' shows that it is difficult but not impossible to overcome the drawbacks of the welfare state and that in this age of globalization and integration, it remains necessary to coordinate policy on a national level as well. In the last section the authors investigate the dynamics of social-economic policy which will have to be developed under increasingly stringent international conditions The ACM Portal is published by the Association for Computing Machinery.

Stationary oscillation for cellular neural networks with time delays and impulses
Authors: Yinping Zhang
Venue: Mathematics and Computers in Simulation (2009)

This paper studies stationary oscillation for a time-varying recurrent cellular neural network with time delays and impulses. In a recent paper, the authors claim that they obtain a criterion of existence, uniqueness, and global exponential stability of periodic solution (i.e. stationary oscillation) for a recurrent cellular neural network with time delays and impulses. We point out that the main result of their paper is incorrect, and present a sufficient condition of stationary oscillation for a time-varying recurrent cellular neural networks with time delays and impulses. An numerical example is given to illustrate the effectiveness of the obtained result.
Detection of Overlapped Ellipses by Combining Region and Edge Data
Authors: Lin Zheng, Quan Liu
Venue: Proceedings of the 4th International Conference on Computer Vision/Computer Graphics CollaborationTechniques (2009)

This paper describes an approach for detecting overlapped ellipses by combining region and edge data. The Principle Component Analysis method is used to give the shape and position of an ellipse. A region based EM iterative algorithm is proposed to calculate the number of ellipses and their initial shapes in the overlapped region. As a result, every edge point is assigned to a certain ellipse by statistics decision. Then an edge fitting algorithm is employed to efine the ellipses' geometric parameters based on the edge data. Above coarse-to-fine algorithm is applied to detect the overlapped fruits and the moving targets. The result is stable and accurate.
Image Segmentation based on Inter-feature Distance Maps
Authors: Susana Álvarez, Xavier Otazu, Maria Vanrell
Venue: Proceeding of the 2005 conference on Artificial Intelligence Research and Development (2005)

In this paper we present an unsupervised colour-texture segmentation method. The novelty of this new approach relies on the definition of the interfeature distance map, which combines different textural properties, either those due to chromaticity variations or those due to intensity changes. The proposed framework works on a multi-channel representation that directly depends on the basic colours perceived in an image, trying to avoid the spatial correlation of usual 3D representations of colour. The textural information derived from intensity changes is added to the multi-channel representation and finally, chromaticity and intensity are combined with the inter-feature distance maps. The behaviour of the approach is tested on a set of natural and synthetic images to demonstrate the capabilities to deal with some representative types of colour-textures which are suggested in this work.
Creating a test corpus of clinical notes manually tagged for part-of-speech information
Authors: Serguei Pakhomov, Anni Coden, Christopher Chute
Venue: Proceedings of the International Joint Workshop on Natural Language Processing in Biomedicine and its Applications (2004)

This paper presents a project whose main goal is to construct a corpus of clinical text manually annotated for part-of-speech information. We describe and discuss the process of training three domain experts to perform linguistic annotation. We list some of the challenges as well as encouraging results pertaining to inter-rater agreement and consistency of annotation. We also present preliminary experimental results indicating the necessity for adapting state-of-the-art POS taggers to the sublanguage domain of medical text.
Locating need-to-translate constant strings for software internationalization
Authors: Xiaoyin Wang, Lu Zhang, Tao Xie, Hong Mei, Jiasu Sun
Venue: Proceedings of the 2009 IEEE 31st International Conference on Software Engineering (2009)

Modern software applications require internationalization to be distributed to different regions of the world. In various situations, many software applications are not internationalized at early stages of development. To internationalize such an existing application, developers need to externalize some hard-coded constant strings to resource files, so that translators can easily translate the application into a local language without modifying its source code. Since not all the constant strings require externalization, locating those need-to-translate constant strings is a necessary task that developers must complete for internationalization. In this paper, we present an approach to automatically locating need-to-translate constant strings. Our approach first collects a list of API methods related to the Graphical User Interface (GUI), and then searches for need-to-translate strings from the invocations of these API methods based on string-taint analysis. We evaluated our approach on four real-world open source applications: RText, Risk, ArtOfIllusion, and Megamek. The results show that our approach effectively locates most of the need-to-translate constant strings in all the four applications.
A Formal Syntax of Natural Languages and the Deductive Grammar
Authors: Yingxu Wang
Venue: Fundamenta Informaticae (2009)

This paper presents a formal syntax framework of natural languages for computational linguistics. The abstract syntax of natural languages, particularly English, and their formal manipulations are described. On the basis of the abstract syntax, a universal language processing model and the deductive grammar of English are developed toward the formalization of Chomsky's universal grammar in linguistics. Comparative analyses of natural and programming languages, as well as the linguistic perception on software engineering, are discussed. A wide range of applications of the deductive grammar of English have been explored in language acquisition, comprehension, generation, and processing in cognitive informatics, computational intelligence, and cognitive computing.
WSFI-Mine: Mining Frequent Patterns in Data Streams
Authors: Younghee Kim, Ungmo Kim
Venue: Proceedings of the 6th International Symposium on Neural Networks: Advances in Neural Networks - Part II (2009)

A data stream is a massive unbounded sequence of data elements continuously generated at a rapid rate. Data mining over data streams should support the flexible trade-off between processing time and mining accuracy. This should occur without a fixed granule of data mining to catch the sensitive change of its mining results as soon as possible. The continuous characteristic of streaming data necessitates the use of algorithms that require only one scan over the stream for knowledge discovery. This paper focuses on research issues concerning mining frequent itemsets in data streams and presents an efficient algorithm WSFI(Weighted Support Frequent Itemsets)-mine to mine all frequent itemsets by one scan from the data stream. WSFI-mine's novel contribution is to effectively execute frequent patterns by generating constraint candidate item sets and extended FPtree-based compact pattern representation under window sliding of the data stream. This method can be achieved effectively with less memory and lowered execution time.

Curriculum learning
Authors: Yoshua Bengio, Jérôme Louradour, Ronan Collobert, Jason Weston
Venue: Proceedings of the 26th Annual International Conference on Machine Learning (2009)

Humans and animals learn much better when the examples are not randomly presented but organized in a meaningful order which illustrates gradually more concepts, and gradually more complex ones. Here, we formalize such training strategies in the context of machine learning, and call them "curriculum learning". In the context of recent research studying the difficulty of training in the presence of non-convex training criteria (for deep deterministic and stochastic neural networks), we explore curriculum learning in various set-ups. The experiments show that significant improvements in generalization can be achieved. We hypothesize that curriculum learning has both an effect on the speed of convergence of the training process to a minimum and, in the case of non-convex criteria, on the quality of the local minima obtained: curriculum learning can be seen as a particular form of continuation method (a general strategy for global optimization of non-convex functions).
Intelligence and Language --How Could Human Being Have Language ?
Authors: Setsuo Ohsuga
Venue: Proceeding of the 2009 conference on Information Modelling and Knowledge Bases XX (2009)

Origin of language is discussed. Language is a media to represent, process and transfer concepts. Before language has been made human being has only biological system to preserve their lives like the other animals. How was concepts made and language originated from there? In this paper a possibility of language having been originated is discussed.
Branchwidth of chordal graphs
Authors: Christophe Paul, Jan Arne Telle
Venue: Discrete Applied Mathematics (2009)

This paper revisits the 'branchwidth territories' of Kloks, Kratochvil and Muller [T. Kloks, J. Kratochvil, H. Muller, New branchwidth territories, in: 16th Ann. Symp. on Theoretical Aspect of Computer Science, STACS, in: Lecture Notes in Computer Science, vol. 1563, 1999, pp. 173-183] to provide a simpler proof, and a faster algorithm for computing the branchwidth of an interval graph. We also generalize the algorithm to the class of chordal graphs, albeit at the expense of exponential running time. Compliance with the ternary constraint of the branchwidth definition is facilitated by a simple new tool called k-troikas: three sets of size at most k each are a k-troika of set S, if any two have union S. We give a straightforward O(m+n+q^2) algorithm, computing branchwidth for an interval graph on m edges, n vertices and q maximal cliques. We also prove a conjecture of Mazoit [F. Mazoit, A general scheme for deciding the branchwidth, Technical Report RR2004-34, LIP - Ecole Normale Superieure de Lyon, 2004. http://www.ens-lyon.fr/LIP/Pub/Rapports/RR/RR2004/RR2004-34.pdf], by showing that branchwidth can be computed in polynomial time for a chordal graph given with a clique tree having a polynomial number of subtrees.
Software development governance: A meta-management perspective
Authors: Paul L. Bannerman
Venue: Proceedings of the 2009 ICSE Workshop on Software Development Governance (2009)

Software development governance is a nascent field of research. Establishing how it is framed early, can significantly affect the progress of contributions. This position paper considers the nature and role of governance in organizations and in the software development domain in particular. In contrast to the dominant functional and structural perspectives, an integrated view of governance is proposed as managing the management of a particular domain (that is, a meta-management perspective). Principles are developed and applied to software development governance and illustrated by a case study.
The Scientific Data Management Center: Providing Technologies for Large Scale Scientific Exploration
Authors: Arie Shoshani
Venue: Proceedings of the 21st International Conference on Scientific and Statistical Database Management (2009)

Managing scientific data has been identified by the scientific community as one of the most important emerging needs because of the sheer volume and increasing complexity of data being collected. Effectively generating, managing, and analyzing this information requires a comprehensive, end-to-end approach to data management that encompasses all of the stages from the initial data acquisition to the final analysis of the data. Fortunately, the data management problems encountered by most scientific domains are common enough to be addressed through shared technology solutions. Based on community input, the SDM center has identified three significant requirements. First, more efficient access to storage systems is needed. In particular, parallel file system and I/O system improvements are needed to write and read large volumes of data without slowing a simulation, analysis, or visualization engine. These processes are complicated by the fact that scientific data are structured differently for specific application domains, and are stored in specialized file formats. Second, scientists require technologies to facilitate better understanding of their data, in particular the ability to effectively perform complex data analysis and searches over extremely large data sets. Specialized feature discovery and statistical analysis techniques are needed before the data can be understood or visualized. Furthermore, interactive analysis requires indexing techniques for efficiently searching and selecting subsets of interest are needed. Finally, generating the data, collecting and storing the results, keeping track of data provenance, data post-processing, and analysis of results is a tedious, fragmented process. Workflow tools for automation of this process in a robust, tractable, and recoverable fashion are required to enhance scientific exploration.
Price Setting in Two-Sided Markets for Internet Connectivity
Authors: Thorsten Hau, Walter Brenner
Venue: Proceedings of the 6th International Workshop on Internet Charging and Qos Technologies: Network Economics for Next Generation Networks (2009)

Due to a lack of incentives, Internet peerings are a notorious bandwidth bottleneck. Through the use of direct interconnection and content delivery networks, content providers are able to provide better services to their customers. These technologies have a profound impact on the business models of internet service providers. Instead of competing for consumers and keeping uplink connection costs low, ISPs face a two-sided market in which they compete for EUs and generate revenues on the CP side of the market. This work presents a formal model for the providers' pricing decision towards content providers and discusses consequences for the Internet.
Ruby on Rails Enterprise Application Development: Plan, Program, Extend Building a complete Ruby on Rails business application from start to finish
Authors: Elliot Smith, Rob Nichols
Venue:  (2007)

This book is aimed at developers who already have some familiarity with the Ruby on Rails framework and who want to move on from the basic tutorials. In particular, it is aimed at those who wish to use the unique attributes of Rails to develop and roll out business applications. It concentrates on application development as a whole process, and is intended to complement existing Rails tutorials. All businesses have processes that can be automated via computer applications, thereby reducing costs and simplifying everyday operations. This book demonstrates that a modern web application framework makes an ideal platform for such applications. It shows how the attributes that make the Rails framework so successful for Internet applications also provide great benefit within a business intranet. These attributes include easy roll-out and update of applications, centralized processing and data handling, simple maintenance, straightforward code development, and scalability. Ruby on Rails is an open-source web application framework ideally suited to building business applications, accelerating and simplifying the creation of database-driven websites. Often shortened to Rails or RoR, it provides a stack of tools to rapidly build web applications based on the Model-View-Controller design pattern. This book covers topics such as installing Ruby, Rubygems, and Rails on Windows, Linux, and Mac OS X; choosing and installing a database; installing an IDE for Rails development; setting up a Subversion repository to manage your code; creating a new Rails application; understanding Rails models; understanding controllers and views; improving user interfaces with Ajax; using Rails plugins to manage file uploads; using Capistrano to manage application deployment; techniques for scaling Rails applications, such as caching and using Apache to proxy through to the Mongrel server. The example application is straightforward to develop, easy to roll out, and simple to maintain. This book concentrates on application development as a whole process and is intended to complement existing Rails tutorials. Each chapter deals with a key feature or functional area of a complex, full-scale Rails application.

Authors: Zhi Tang, Liangcai Gao, Aixia Jia, Xiaofan Lin
Venue: Proceedings of the 9th ACM/IEEE-CS joint conference on Digital libraries (2009)

We propose a new document container format (XEB, eXtensible Electronic Book) based on block mechanism to efficiently process markup language documents in handheld devices. And random document access is also supported in the format through a pagination mechanism. The format has already been applied to a number of handheld devices' Chinese E-book readersand XEB documents can be downloaded from a Chinese E-book store.
Topic segmentation of dialogue
Authors: Jaime Arguello, Carolyn Rosé
Venue: Proceedings of the HLT-NAACL 2006 Workshop on Analyzing Conversations in Text and Speech (2006)

We introduce a novel topic segmentation approach that combines evidence of topic shifts from lexical cohesion with linguistic evidence such as syntactically distinct features of segment initial and final contributions. Our evaluation shows that this hybrid approach outperforms state-of-the-art algorithms even when applied to loosely structured, spontaneous dialogue. Further analysis reveals that using dialogue exchanges versus dialogue contributions improves topic segmentation quality.
Evaluating the Jaccard-Tanimoto Index on Multi-core Architectures
Authors: Vipin Sachdeva, Douglas M. Freimuth, Chris Mueller
Venue: Proceedings of the 9th International Conference on Computational Science: Part I (2009)

The Jaccard/Tanimoto coefficient is an important workload, used in a large variety of problems including drug design fingerprinting, clustering analysis, similarity web searching and image segmentation. This paper evaluates the Jaccard coefficient on three platforms: the Cell Broadband EngineTMprocessor Intel ®Xeon ®dual-core platform and Nvidia ®8800 GTX GPU. In our work, we have developed a novel parallel algorithm specially suited for the Cell/B.E. architecture for all-to-all Jaccard comparisons, that minimizes DMA transfers and reuses data in the local store. We show that our implementation on Cell/B.E. outperforms the implementations on comparable Intel platforms by 6-20X with full accuracy, and from 10-50X in reduced accuracy mode, depending on the size of the data, and by more than 60X compared to Nvidia 8800 GTX. In addition to performance, we also discuss in detail our efforts to optimize our workload on these architectures and explain how avenues for optimization on each architecture are very different and vary from one architecture to another for our workload. Our work shows that the algorithms or kernels employed for the Jaccard coefficient calculation are heavily dependent on the traits of the target hardware.

DFS* and the Traveling Tournament Problem
Authors: David C. Uthus, Patricia J. Riddle, Hans W. Guesgen
Venue: Proceedings of the 6th International Conference on Integration of AI and OR Techniques in Constraint Programming for Combinatorial Optimization Problems (2009)

Our paper presents a new exact method to solve the traveling tournament problem. More precisely, we apply DFS* to this problem and improve its performance by keeping the expensive heuristic estimates in memory to help greatly cut down the computational time needed. We further improve the performance by exploiting a symmetry property found in the traveling tournament problem. Our results show that our approach is one of the top performing approaches for this problem. It is able to find known optimal solutions in a much smaller amount of computational time than past approaches, to find a new optimal solution, and to improve the lower bounds of larger problem instances which do not have known optimal solutions. As a final contribution, we also introduce a new set of problem instances to diversify the available instance sets for the traveling tournament problem.
