Noise reduction of hyperspectral data using singular spectral analysis
Authors: Baoxin Hu, Qingmou Li, A. Smith
Venue: International Journal of Remote Sensing (2009)

In this study, a new noise reduction algorithm based on singular spectral analysis (SSA) was developed to reduce the noise in hyperspectral data. With this SSA-based approach, the reflectance spectrum of a given pixel in a hyperspectral cube is transformed into its state space. The state space is dynamically constructed and characterized by irregular bases, which allows the proposed approach to reduce noises while keeping the absorption features of surface objects. The performance of the developed method was verified on three datasets: two simulated reflectance spectra with several narrow absorption features and a CHRIS (Compact High Resolution Imaging Spectrometer) data cube over agricultural fields. Our results demonstrated the effectiveness of the SSA-based approach in improving the signal-to-noise ratio of hyperspectral data, while keeping the 'sharp features' in the reflectance spectra. The results also show that the proposed SSA method outperforms the commonly used MNF (minimum noise fraction) and wavelet-based noise reduction methods and it improved vegetation cover classification accuracy by 6%.
The UK e-Science Program and the Grid
Authors: Tony Hey
Venue: Proceedings of the 4th International Symposium on High Performance Computing (2009)

The talk describes the £ 120M UK `e-Science' initiative and begins by defining what is meant by the term e-Science. The majority of the £ 120M, some £ 85M, is for the support of large-scale e-Science projects in many areas of science and engineering. The infrastructure needed to support such projects needs to allow sharing of distributed and heterogeneous computational and data resources and support effective collaboration between groups of scientists. Such an infrastructure is commonly referred to as the Grid. The remaining funds, some £ 35M, constitute the e-Science `Core Program' and is intended to encourage the development of robust and generic Grid middleware in collaboration with industry. The key elements of the Core Program will be described including the construction of a UK e-Science Grid. In addition, the talk will include a description of the pilot projects that have so far received funding. These span a range of disciplines from particle physics and astronomy to engineering and healthcare. We conclude with some remarks about the need to develop a data architecture for the Grid that will allow federated access to relational databases as well as flat files.
A Visual and Semantic Image Retrieval Method Based on Similarity Computing with Query-Context Recognition
Authors: Xing Chen, Yasushi Kiyoki
Venue: Proceeding of the 2007 conference on Information Modelling and Knowledge Bases XVIII (2007)

This paper presents an image retrieval method based on visual and semantic similarity computing with a query-context recognition mechanism. The motivation of our work is to solve the problem which can be described as that if only the visual similarity or only the semantic similarity judgment is performed on image retrieval, the retrieval results do not always match the query intentions of users. Our central idea is that similarity computing has to be performed between visual and semantic levels. To understand the relationship between the visual factors and the semantic factors in images, we have performed experimental studies. From our experimental studies, it is found that it is possible to extract semantic factors from the visual factors of images. Furthermore, it is found that users' query intention can be detected from the difference of images in queries. Based on the experimental results, we develop a method to implement both the semantic and visual similarity judgment for image retrieval. In this method, several images are required to be given as the key images in a query for users to indicate their query intentions. Furthermore, an adjusting value is used for users to indicate their query intentions, intending on the visual similarity or the semantic similarity. Both the visual and semantic factors are extracted from the key images and the similarity computation is performed on the extracted factors. The effectiveness of the method is clarified based on our experimental results.

Authors: Muhammad Hisyam Lee, Izman Sudin, Goh Eng Ken, Azami Zaharim
Venue: Proceedings of the 13th WSEAS international conference on Applied mathematics (2008)

An experiment was conducted to compare the effects of ultrasonic and non-ultrasonic on glass lens using rotary ultrasonic machining (RUM) technology. The primary objective of this study is to analyze the experimental results of the grinding operations using Taguchi method. Feed rate and frequency are the main process parameters to be tested in this experiment. A three-level orthogonal array table had been used to determine the signal-to-noise (S/N) ratios based on Taguchi's design of experiments and analysis of variance (ANOVA) was performed to study the relative significance of both factors in affecting the surface roughness of glass lens. The final results showed that the process output is greatly influenced by the feed rate rather than the frequency and low feed rate without frequency is identified to be the most optimum factor settings. The data of the confirmation run are provided to verify the effectiveness of Taguchi's approach.
Computer game design and the imaginative play of young children
Authors: Irina Verenikina, Jan Herrington
Venue: Proceedings of the 8th International Conference on Interaction Design and Children (2009)

This paper discusses preliminary findings of the study of computer game design in relation to current understanding of imaginative play and its developmental value for young children. The crucial role of children's play in their development is well documented. A number of criteria, which are essential in building a foundation for children's cognitive development in play, were identified based on a literature review of the theoretical and empirical studies of child's play. The identified criteria were utilized to observe two young children playing various types of computer games to explore the opportunities that the games provide for imaginative play in the early childhood years.

Authors: Lavdim Kurtaj, Vjosa Shatri
Venue: Proceedings of the 10th WSEAS international conference on Automation & information (2009)

Potato chips are product with irregular forms with complex flow dynamics. Packing with narrow tolerance is done by combinatorial weighing machine. For controlling this complex machine it is of great importance to have well designed human-machine interface (HMI). To minimize human intervention on machine operation of great importance is quality of its control algorithm. To gain an insight into the process of vibratory conveying and combinatorial weighing of potato chips experimental on-line setup was created. Setup contains refurbished combinatorial weigher and personal computer (PC) with network control structure. First, a short introduction to the chain of supplying, weighing and packing at potato chips production line is given. It is described briefly principle of combinatorial weighing. Next, experimental setup was described, from constructive parts, to hardware and software implementation. RS485 serial communication line with MODBUS protocol was used for networking master and three slave control units. Application software and implemented functions for making flexible development system are presented. HMI and MODBUS protocol were implemented with Visual Basic. Finally, tests results are given and show flexibility of setup in implementing real-time closed-loop control over MODBUS communication channel for combinatorial weigher at potato chips production line.

Anonymizing location-based RFID data
Authors: Jarmanjit Singh, Qing Shi, Harpreet Sandhu, Benjamin C. M. Fung
Venue: Proceedings of the 2nd Canadian Conference on Computer Science and Software Engineering (2009)

In this paper, we study the problem of anonymizing high dimensional location-based RFID data for mining or research purposes. We consider the case where RFID cards are used for purchasing in place of magnetic cards. Databases containing such transactions of card holders could be very huge in number of records (equals to number of users) and dimensions (could be equal to the domain of locations where users are allowed to use their cards). This huge database containing user's purchasing history can be mined to find interesting knowledge. At the same time publication of data would cause re-identification attacks by adversaries who have partial knowledge about transactions. Therefore, before publishing transactional data, it should be made k-anonymous. However, traditional k-anonymity methods were designed to k-anonymize low dimensional databases and are not scalable much to produce good results when it comes to k-anonymous large high dimensional databases. In this paper, we provide a solution modeling k-anonymity principle to protect the privacy in publication of high dimensional databases. We propose greedy approach, which scales much better and in most cases finds solution close to the optimal. The proposed algorithm is experimentally evaluated.
Exploring text and image features to classify images in bioscience literature
Authors: Barry Rafkind, Minsuk Lee, Shih-Fu Chang, Hong Yu
Venue: Proceedings of the Workshop on Linking Natural Language Processing and Biology: Towards Deeper Biological Literature Analysis (2006)

A picture is worth a thousand words. Biomedical researchers tend to incorporate a significant number of images (i.e., figures or tables) in their publications to report experimental results, to present research models, and to display examples of biomedical objects. Unfortunately, this wealth of information remains virtually inaccessible without automatic systems to organize these images. We explored supervised machine-learning systems using Support Vector Machines to automatically classify images into six representative categories based on text, image, and the fusion of both. Our experiments show a significant improvement in the average F-score of the fusion classifier (73.66%) as compared with classifiers just based on image (50.74%) or text features (68.54%).
Prediction of Chaotic Time Series Based on Neural Network with Legendre Polynomials
Authors: Hongwei Wang, Hong Gu
Venue: Proceedings of the 6th International Symposium on Neural Networks on Advances in Neural Networks (2009)

In this paper, a modeling method based on the orthogonal function neural network is proposed. Legendre orthogonal polynomials are selected as the basic functions of the neural network. Kalman filtering algorithm with singular value decomposition is used to confirm the parameters of orthogonal function neural network in order to avoid error delivery and error accumulation. To demonstrate the performance of this modeling method, the simulation on Mackey-Glass chaotic time series is performed. The results show that this method provides effective and accurate prediction.
Refactoring and the evolution of Fortran
Authors: Jeffrey L. Overbey, Stas Negara, Ralph E. Johnson
Venue: Proceedings of the 2009 ICSE Workshop on Software Engineering for Computational Science and Engineering (2009)

Successful languages like Fortran keep changing and tend to become more complex, often containing older features that are rarely used. Complexity makes languages harder to use and makes it harder to build tools for them. A refactoring tool can eliminate use of these features from programs; this makes programs easier to understand and maintain, and it can simplify building certain programming tools. This is illustrated by using Photran, a refactoring tool for Fortran, to eliminate global variables from Fortran programs so that they can be used with Adaptive MPI, a version of MPI that performs load balancing.
Towards the next generation of bug tracking systems
Authors: Sascha Just, Rahul Premraj, Thomas Zimmermann
Venue: Proceedings of the 2008 IEEE Symposium on Visual Languages and Human-Centric Computing (2008)

Developers typically rely on the information submitted by end-users to resolve bugs. We conducted a survey on information needs and commonly faced problems with bug reporting among several hundred developers and users of the APACHE, ECLIPSE and MOZILLA projects. In this paper, we present the results of a card sort on the 175 comments sent back to us by the responders of the survey. The card sort revealed several hurdles involved in reporting and resolving bugs, which we present in a collection of recommendations for the design of new bug tracking systems. Such systems could provide contextual assistance, reminders to add information, and most important, assistance to collect and report crucial information to developers.
Multimodal analysis of expressive human communication: speech and gesture interplay
Authors: Shrikanth S. Narayanan
Venue:  (2008)

The verbal and non-verbal channels of human communication are internally and intricately connected. As a result, gestures and speech present high levels of correlation and coordination. This relationship is greatly affected by the linguistic and emotional content of the message being communicated. The interplay is observed across the different communication channels such as various aspects of speech, facial expressions, and movements of the hands, head and body. For example, facial expressions and prosodic speech tend to have a stronger emotional modulation when the vocal tract is physically constrained by the articulation to convey other linguistic communicative goals. As a result of the analysis, applications in recognition and synthesis of expressive communication are presented. From an emotion recognition perspective, we propose to build acoustically neutral models, which are used to measure the degree of similarity between the input speech and neutral speech. A fitness measure is then used as feature for classification, achieving better performance than conventional classification schemes in terms of accuracy and robustness. In addition to detecting users' emotions, we analyze how to use such ideas for meta-analysis of user behavior such as in automatically monitoring and tracking the behaviors, strategies and engagement of the participants in multiperson interactions. We describe a case of study of an intelligent meeting environment equipped with audio-visual sensors. We accurately estimate in real-time not only the flow of the interaction, but also how dominant and engaged each participant was during the discussion. Finally, we show examples of how to synthesize expressive behavior by exploiting interrelation between speech and gestures. We propose to synthesize natural head motion sequences from acoustic prosodic features by sampling from trained Hidden Markov Models (HMMs). Our comparison experiments show that the synthesized head motions are perceived as natural as the captured head motion sequences.

End-user software development in a scientific organization
Authors: Mark Vigder
Venue: Proceedings of the 2009 ICSE Workshop on Software Engineering Foundations for End User Programming (2009)

Scientific and engineering research is dependent on effective use of software artifacts; many of these artifacts are produced by the scientists themselves, rather than by trained software engineers. In order to improve the productivity of groups involved in scientific research, we have undertaken a project to understand the types of software development being undertaken by scientists, and to build a system that will help these end-users to build and manage the software. This paper summarizes the issues we have identified and the system we have built to support the scientists in their software engineering activities.
Power optimized digitally programmable delay element
Authors: Sekedi Bomeh Kobenge, Huazhong Yang
Venue: Proceedings of the 9th WSEAS international conference on Robotics, control and manufacturing technology (2009)

A low power monotonic digitally programmable delay element is proposed in this paper. A single edge topology, used for controlling the rising edge only, and a double edge topology used for adjusting both the rising and falling edges of the input clock signal are described. Switched current mirror technique, gate decoupling and a Schmitt type inverter are used to reduce the static and dynamic power consumption. Simulations of the delay element with a 1V power supply show 40% power saving while operating at 450MHz.
Polynomial-Time Algorithm for Sorting by Generalized Translocations
Authors: Xiao Yin, Daming Zhu
Venue: Proceedings of the 6th Annual Conference on Theory and Applications of Models of Computation (2009)

Translocation is a prevalent rearrangement event in the evolution of multi-chromosomal species which exchanges ends between two chromosomes. A translocation is reciprocal if none of the exchanged ends is empty; otherwise, non-reciprocal. Given two signed multi-chromosomal genomes A and B, the problem of sorting by translocations is to find a shortest sequence of translocations transforming A into B. Several polynomial algorithms have been presented, all of them only allowing reciprocal translocations. Thus they can only be applied to a pair of genomes having the same set of chromosome ends. Such a restriction can be removed if non-reciprocal translocations are also allowed. In this paper, for the first time, we study the problem of sorting by generalized translocations, which allows both reciprocal translocations and non-reciprocal translocations. We present an exact formula for computing the generalized translocation distance, which leads to a polynomial algorithm for this problem.

Google and the Myth of Universal Knowledge: A View from Europe
Authors: Jean-Noel Jeanneney
Venue:  (2007)

The recent announcement that Google would digitize the holdings of several major libraries sent shock waves through the book industry and academe. Google presented this digital repository as a first step towards a long-dreamed-of universal library, but skeptics were quick to raise a number of concerns about the potential for copyright infringement and unanticipated effects on the business of research and publishing.Jean-Nol Jeanneney, president of Frances Bibliothque Nationale, here takes aim at what he sees as a far more troubling aspect of Googles Library Project: its potential to misrepresentand even damagethe worlds cultural heritage. In this impassioned work, Jeanneney argues that Googles unsystematic digitization of books from a few partner libraries and its reliance on works written mostly in Englishconstitute acts of selection that can onlyextend the dominance of American culture abroad.As a leading librarian, Jeanneney remains enthusiastic about the archival potential of the Web. But he argues that the short-term thinking characterized by Googles digital repository must be countered by long-term planning on the part of cultural and governmental institutions worldwidea serious effort to create a truly comprehensive library, one based on the politics of inclusion and multiculturalism.The president of the French national library has made himself the frontman in what he sees as a struggle to save cultural diversity.

Authors: Yair Neuman, Ophir Nave
Venue: Information Sciences: an International Journal (2009)

Excavating the meaning of a target term is a challenge facing information sciences and various applications of Web 3.0. In this paper, we present a novel method for excavating the meaning of a target term by analyzing metaphors in which the term is embedded. More specifically, we (1) review some of the basic theoretical difficulties associated with the dominant cognitive theories of metaphor; (2) outline a mathematical model of metaphor that addresses some of these difficulties; (3) introduce a novel method for excavating metaphor-based meaning; and (4) illustrate the relevance of the methodology and the potential applications of the model with a concrete example.
