Megasonic agitation for enhanced electrodeposition of copper
Authors: Jens Georg Kaufmann, Marc P. Y. Desmulliez, Yingtao Tian, Dennis Price, Mike Hughes, Nadia Strusevich, Chris Bailey, Changqing Liu, David Hutt
Venue: Microsystem Technologies (2009)

In this paper we propose an agitation method based on megasonic acoustic streaming to overcome the limitations in plating rate and uniformity of the metal deposits during the electroplating process. Megasonic agitation at a frequency of 1&#x00a0;MHz allows the reduction of the thickness of the Nernst diffusion layer to less than 600&#x00a0;nm. Two applications that demonstrate the benefits of megasonic acoustic streaming are presented: the formation of uniform ultra-fine pitch flip-chip bumps and the metallisation of high aspect ratio microvias. For the latter application, a multi-physics based numerical simulation is implemented to describe the hydrodynamics introduced by the acoustic waves as they travel inside the deep microvias.
Translation Accuracy Influence on the Retrieval Results
Authors: Jolanta Mizera-Pietraszko, Aleksander Zgrzywa
Venue: Proceeding of the 2008 conference on New Trends in Multimedia and Network Information Systems (2008)

This report presents a novel methodology in evaluating performance of the popular on-line multilingual search engine AltaVista. We study some crucial aspects of natural language that usually disrupt translation process and the extend to which it influences retrieval results. Having prepared the test set, we analyze phenomena of an English and French language pair in relation to the strategy of browsing the Web for documents with the features specified in the query. Using Natural Language Processing techniques, we test a Machine Translation system performance in order to improve the translation quality, which in turn has an impact on the results of information retrieval in a language other than the query language.
What happens when facebook is gone?
Authors: Frank McCown, Michael L. Nelson
Venue: Proceedings of the 9th ACM/IEEE-CS joint conference on Digital libraries (2009)

Web users are spending more of their time and creative energies within online social networking systems. While many of these networks allow users to export their personal data or expose themselves to third-party web archiving, some do not. Facebook, one of the most popular social networking websites, is one example of a "walled garden" where users' activities are trapped. We examine a variety of techniques for extracting users' activities from Facebook (and by extension, other social networking systems) for the personal archive and for the third-party archiver. Our framework could be applied to any walled garden where personal user data is being locked.
Relating web pages to enable information-gathering tasks
Authors: Amitabha Bagchi, Garima Lahoti
Venue: Proceedings of the 20th ACM conference on Hypertext and hypermedia (2009)

We argue that relationships between Web pages are functions of the user's intent. We identify a class of Web tasks - information-gathering - that can be facilitated by providing links to pages related to the page the user is currently viewing. We define three kinds of intentional relationships that correspond to whether the user is a) seeking sources of information, b) reading pages which provide information, or c) surfing through pages as part of an extended information-gathering process. We show that these three relationships can be mined using a combination of textual and link information and provide three scoring mechanisms that correspond to them: SeekRel, FactRel and SurfRel. These scoring mechanisms incorporate both textual and link information. We build a set of capacitated subnetworks, each corresponding to a particular keyword. Scores are computed by computing flows on these subnetworks. The capacities of the links are derived from the hub and authority values of the nodes they connect, following the work of Kleinberg (1998) on assigning authority to pages in hyperlinked environments. We evaluated our scoring mechanism by running experiments on four data sets taken from the Web. We present user evaluations of the relevance of the top results returned by our scoring mechanisms and compare those to the top results returned by Google's Similar Pages feature, and the Companion algorithm (Dean and Henzinger, 1999).
Unifying aspect- and object-oriented design
Authors: Hridesh Rajan, Kevin J. Sullivan
Venue: ACM Transactions on Software Engineering and Methodology (TOSEM) (2009)

The contribution of this work is the design and evaluation of a programming language model that unifies aspects and classes as they appear in AspectJ-like languages. We show that our model preserves the capabilities of AspectJ-like languages, while improving the conceptual integrity of the language model and the compositionality of modules. The improvement in conceptual integrity is manifested by the reduction of specialized constructs in favor of uniform orthogonal constructs. The enhancement in compositionality is demonstrated by better modularization of integration and higher-order crosscutting concerns.
Wireless reliability: Rethinking 802.11 packet loss
Authors: David C. Salyers, Aaron D. Striegel, Christian Poellabauer
Venue: Proceedings of the 2008 International Symposium on a World of Wireless, Mobile and Multimedia Networks (2008)

Wireless enabled devices are ubiquitous in today’s computing environment. Businesses, universities, and home users alike are taking advantage of the easy deployment of wireless devices to provide network connectivity without the expense associated with wired connections. Unfortunately, the wireless medium is inherently unreliable resulting in significant work having been performed to better understand the characteristics of the wireless environment. Notably, many works attribute the primary source of wireless losses to errors in the physical medium. In contrast, our work shows that the wireless device itself plays a significant role in 802.11 packet loss. In our experiments, we found that the correlation of loss between multiple closely located (within one λ) receivers is low with the majority of loss instances only occurring at one of the receivers. We conducted extensive experiments on the individual loss characteristics of five common wireless cards, showing that while the cards behave similarly on the macro-level (e.g. similar overall loss rates), the cards perform quite differently on the micro-level (e.g. burstiness, correlation, and consistency).

A simple approach to nonlinear tensile stiffness for accurate cloth simulation
Authors: Pascal Volino, Nadia Magnenat-Thalmann, Francois Faure
Venue: ACM Transactions on Graphics (TOG) (2009)

Recent mechanical models for cloth simulation have evolved toward accurate representation of elastic stiffness based on continuum mechanics, converging to formulations that are largely analogous to fast finite element methods. In the context of tensile deformations, these formulations usually involve the linearization of tensors, so as to express linear elasticity in a simple way. However, this approach needs significant adaptations and approximations for dealing with the nonlinearities resulting from large cloth deformations. Toward our objective of accurately simulating the nonlinear properties of cloth, we show that this linearization can indeed be avoided and replaced by adapted strain-stress laws that precisely describe the nonlinear behavior of the material. This leads to highly streamlined computations that are particularly efficient for simulating the nonlinear anisotropic tensile elasticity of highly deformable surfaces. We demonstrate the efficiency of this method with examples related to accurate garment simulation from experimental tensile curves measured on actual materials.
Using ant colony systems with pheromone dispersion in the traveling salesman problem
Authors: José Carlos Becceneri, Sandra Sandri, E.F. Pacheco da Luz
Venue: Proceeding of the 2008 conference on Artificial Intelligence Research and Development: Proceedings of the 11th International Conference of the Catalan Association for Artificial Intelligence (2008)

Here we investigate the use of Ant Colony Systems (ACS) for the Traveling Salesman Problem (TSP). We propose the use of a modified ACS for graph problems in which we allow an artificial ant to lay down pheromone, not only on the edges in its path, but also on edges close to it: the closer a given edge is to one of those in the ant's path, the more pheromone it receives. The notion of edge closeness in the TSP takes into account not only the closeness among the nodes composing the edges but also the edges orientation.
A Generalization of the Bent-Function Sequence Construction
Authors: Yongbo Xia, Yan Sui, Junhao Hu
Venue: Proceedings of the 6th International Symposium on Neural Networks: Advances in Neural Networks - Part III (2009)

The construction method of bent-function sequences is generalized to construct sequences with low correlation from functions with low maximal Walsh transform. In detail, for any nonlinear function from $F_{2^e}^{k}$ to F 2 with maximum magnitude spectra A, a family of sequences with period 22ek ¿ 1 can be constructed. There are 2 ek sequences within a family and the maximum nontrival auto and cross-correlation values equals A 2 + 1. The linear span of these proposed sequences is discussed and the lower bound can be greater than $\left(\begin{array}{cc}ek\\d\end{array}\right)2^{d}+2ek$, where 2 ≤ d < ek.
Gesture in automatic discourse processing
Authors: Regina Barzilay, Randall Davis
Venue:  (2008)

Computers cannot fully understand spoken language without access to the wide range of modalities that accompany speech. This thesis addresses the particularly expressive modality of hand gesture, and focuses on building structured statistical models at the intersection of speech, vision, and meaning. My approach is distinguished in two key respects. First, gestural patterns are leveraged to discover parallel structures in the meaning of the associated speech. This differs from prior work that attempted to interpret individual gestures directly, an approach that was prone to a lack of generality across speakers. Second, I present novel, structured statistical models for multimodal language processing, which enable learning about gesture in its linguistic context, rather than in the abstract. These ideas find successful application in a variety of language processing tasks: resolving ambiguous noun phrases, segmenting speech into topics, and producing keyframe summaries of spoken language. In all three cases, the addition of gestural features&mdash;extracted automatically from video&mdash;yields significantly improved performance over a state-of-the-art text-only alternative. This marks the first demonstration that hand gesture improves automatic discourse processing. (Copies available exclusively from MIT Libraries, Rm. 14-0551, Cambridge, MA 02139-4307.

Dialog Convergence and Learning
Authors: Arthur Ward, Diane Litman
Venue: Proceeding of the 2007 conference on Artificial Intelligence in Education: Building Technology Rich Learning Contexts That Work (2007)

In this paper we examine whether the student-to-tutor convergence of lexical and speech features is a useful predictor of learning in a corpus of spoken tutorial dialogs. This possibility is raised by the Interactive Alignment Theory, which suggests a connection between convergence of speech features and the amount of semantic alignment between partners in a dialog. A number of studies have shown that users converge their speech productions toward dialog systems. If, as we hypothesize, semantic alignment between a student and a tutor (or tutoring system) is associated with learning, then this convergence may be correlated with learning gains. We present evidence that both lexical convergence and convergence of an acoustic/prosodic feature are useful features for predicting learning in our corpora. We also find that our measure of lexical convergence provides a stronger correlation with learning in a human/computer corpus than did a previous measure of lexical cohesion.

Verified abstractions on developers' desks
Authors: Viktor Kuncak
Venue: International Workshop on Aliasing, Confinement and Ownership in Object-Oriented Programming (2009)

Verified data abstraction. Data abstraction has long been recognized as a methodology to decompose the verification problem into data structure implementation and the algorithm that uses the data structure [3, 8]. Today we are close to being in a position to incorporate verified data abstraction into programming languages and systems. We discuss the ingreedients needed to make verified data abstraction practical: program verification, specification-based testing, program analysis, programming methodology, as well as programming language design. We draw our examples from the systems Hob [5] and Jahob [4, 12] that implement verified data abstractions, as well as our recent work on verifying properties of Scala programs [2].
Combining Virtual Organization and Local Policies for Automated Configuration of Grid Services
Authors: Shishir Bharathi, Beom Kun Kim, Ann Chervenak, Robert Schuler
Venue: Proceeding of the 2005 conference on Self-Organization and Autonomic Informatics (I) (2005)

We investigate approaches for the automated configuration of distributed Grid services. In particular, we implement several approaches for combining configuration information specified by a group of collaborating institutions (a Virtual Organization or VO) with local configuration parameters. We describe our implementation of merging strategies for configuring the Globus Replica Location Service. Based on our initial work, we describe outstanding issues for merging local and VO configuration policies and for resolving conflicting policies.
Information Extraction from A Whole Web Site
Authors: Xiaoying Gao, Mengjie Zhang
Venue: Proceeding of the 2006 conference on Advances in Intelligent IT: Active Media Technology 2006 (2006)

This paper focuses on information extraction from one site rather than from one page. A new directed-acyclic graph based representation method is introduced for representing link structures on the Web sites. A rule based language is developed for writing extraction rules. The approach is examined and tested on 42 Web sites in six different domains. The results suggest that the system can successfully extract most relevant information from Web sites in different domains.

Authors: Adnan Ibrahim, K. Sopian, M. Y. Othman, M. H. Ruslan, M. A. Alghoul, M. Yahya, Azami Zaharim
Venue: Proceedings of the 7th WSEAS international conference on System science and simulation in engineering (2008)

The main concept of developing the hybrid Photovoltaic/Thermal (PV/T) is to increase the efficiency of the solar and thermal collector. It is known that the efficiency of the Photovoltaic solar collector is decreases when the ambient temperature increased and vice verse. In this systsem, the heat, gain from the sun, is absorbed to the PV panel and convert it to electricity energy. Some of this energy is then transfered to the absorber collector underneath the PV module as a waste energy. Special design configurations of absorber collector has been designed, investigated and compared. Simulation has been performed to determine the absorption of the heat that influences the total efficiency of the system under certain range of conditions. The collector is represented as a flat plate thermal collector with single glazing sheet. The simulation results of the system shows that at certain particular time, it can generates the total efficiency of 63.55% with electrical efficiency of 11.39% at ambient temperature set between 21 to 36°C, fluid flow rate at 0.02kg/s and solar radiation between 700 to 800 W/m2.(Typical clear day).
An HMM approach to realistic haptic human-robot interaction
Authors: Zheng Wang, Angelika Peer, Martin Buss
Venue: Proceedings of the World Haptics 2009 - Third Joint EuroHaptics conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (2009)

A robot controller is developed for human-robot handshaking. The focus of the work is to provide realistic experiences for the human participant in haptic interactions with a robot. To achieve this goal, a position-based admittance controller is implemented. By using haptic data as inputs, a Hidden Markov Model-based high-level controller is used to estimate human intentions and modify the reference trajectory accordingly. The overall control framework is implemented onto a robot with validation experiments carried out with human participants.
Task distribution using factoring load balancing in Master--Worker applications
Authors: A. Moreno, E. Cesar, J. Sorribes, T. Margalef, E. Luque
Venue: Information Processing Letters (2009)

Load imbalance among workers is one of the main causes of performance shortcomings in Master-Worker applications. We have observed that this problem is very similar to the one of scheduling distributed parallel loops, which has been widely in the literature. Thus, we have adapted one of the most successful algorithms, known as Factoring, to be used for Master-Worker applications. This has leads to a simple an elegant strategy that can be used to obtain an excellent automatic and dynamic load balancing strategy for the workers. Finally, we have assessed the resulting strategy through extensive experimentation and simulation.
A General-Purpose FPGA-Based Reconfigurable Platform for Video and Image Processing
Authors: Jie Li, Haibo He, Hong Man, Sachi Desai
Venue: Proceedings of the 6th International Symposium on Neural Networks: Advances in Neural Networks - Part III (2009)

This paper presents a general-purpose, multi-task, and reconfigurable platform for video and image processing. With the increasing requirements of processing power in many of today's video and image processing applications, it is important to go beyond the software implementation to provide a real-time, low cost, high performance, and scalable hardware platform. In this paper, we propose a system by using the powerful parallel processing architecture in the Field Programmable Gate Array (FPGA) to achieve this objective. Based on the proposed system level architecture and design strategies, a prototype system is developed based on the Xilinx Virtex-II FPGA with the integration of embedded processor, memory control and interface technologies. Our system includes different functional modules, such as edge detection, zoom-in and zoom-out functions, which provides the flexibility of using this system as a general video processing platform according to different application requirements. The final system utilizes about 20% of logic resource, 50% of memory on chip, and has total power consumption around 203 mw.
Towards model structuring based on flow diagram decomposition
Authors: Arend Rensink, Maria Zimakova
Venue: Proceedings of the 1st Workshop on Behaviour Modelling in Model-Driven Architecture (2009)

The key challenge of model transformations in model-driven development is in transforming higher-level abstract models into more concrete ones that can be used to generate implementation level models, including executable business process representations and program code. Many of the modelling languages (like UML Activity Diagrams or BPMN) use unstructured flow graphs to describe the operation sequence of a business process. If a structured language is chosen as the executable representation, it is difficult to compile the unstructured flows into structured statements. Even if a target language structure contains goto-like statements it is often simpler and more efficient to deal with programs that have structured control flow to make the executable representation more understandable. In this paper, we take a first step towards an implementation of existing decomposition methods using graph transformations, and we evaluate their effectiveness with a view to readability and essential complexity measures.
