Privacy-Aware Access Control through Negotiation in Daily Life Service
Authors: Hyun-A Park, Justin Zhan, Dong Hoon Lee
Venue: Proceedings of the IEEE ISI 2008 PAISI, PACCF, and SOCO international workshops on Intelligence and Security Informatics (2008)

As users are participating in various social contexts, some projects such as MobiLife and MyLifeBits are developing a facility to commence daily life service. This enables users to store all their daily events which can be collected using their mobile device. These data can be shared with other people or some service providers only if the user agrees. However, in the cases of inter-domain web service usage or sharing their data with others, there are some potential problems about privacy. To solve these problems, we propose a new method, privacy-aware access control through negotiation process (N-PAC). This method enables a user to accomplish self-determination and self-control of personal information in more realistic application environments.

Venue: Proceedings of the 2nd international conference on Combinatorial Optimization and Applications (2008)

We present an explicit formula of the surface area of the (n, k)-star graphs , i.e., |{v|d(e, v) = d}|, where e is the identity node of such a graph; by identifying the cyclic structures of all the nodes in the graph, presenting a minimum routing algorithm between any node in the graph and e, and enumerating those nodes v, such that d(e, v) = d.
Monocular Head Pose Estimation
Authors: Pedro Martins, Jorge Batista
Venue: Proceedings of the 5th international conference on Image Analysis and Recognition (2008)

This work addresses the problem of human head pose estimation from single view images. 3D rigid head pose is estimated combining Active Appearance Models (AAM) with Pose from Orthography and Scaling with ITerations (POSIT). AAM shape landmarks are tracked over time and used in POSIT for pose estimation. A statistical anthropometric 3D model is used as reference. Several experiences were performed comparing our results with a planar ground truth. These experiments shows that orientations and distances were, on average, found within 2° or 1cm standard deviations respectively.
Conceptual flexibility in the human brain: Dynamic recruitment of semantic maps from visual, motor, and motion-related areas
Authors: Klaus Hoenig, Eun-Jin Sim, Viktor Bochev, Bärbel Herrnberger, Markus Kiefer
Venue: Journal of Cognitive Neuroscience (2008)

Traditionally, concepts are assumed to be situational invariant mental knowledge entities (conceptual stability), which are represented in a unitary brain system distinct from sensory and motor areas (amodality). However, accumulating evidence suggests that concepts are embodied in perception and action in that their conceptual features are stored within modality-specific semantic maps in the sensory and motor cortex. Nonetheless, the first traditional assumption of conceptual stability largely remains unquestioned. Here, we tested the notion of flexible concepts using functional magnetic resonance imaging and event-related potentials (ERPs) during the verification of two attribute types (visual, action-related) for words denoting artifactual and natural objects. Functional imaging predominantly revealed crossover interactions between category and attribute type in visual, motor, and motion-related brain areas, indicating that access to conceptual knowledge is strongly modulated by attribute type: Activity in these areas was highest when nondominant conceptual attributes had to be verified. ERPs indicated that these category-attribute interactions emerged as early as 116 msec after stimulus onset, suggesting that they reflect rapid access to conceptual features rather than postconceptual processing. Our results suggest that concepts are situational-dependent mental entities. They are composed of semantic features which are flexibly recruited from distributed, yet localized, semantic maps in modality-specific brain regions depending on contextual constraints.

Controllability of Static CMOS Circuits for Timing Characterization
Authors: Ramyanshu Datta, Ravi Gupta, Antony Sebastine, Jacob A. Abraham, Manuel D'Abreu
Venue: Journal of Electronic Testing: Theory and Applications (2008)

Timing violations, also known as delay faults, are a major source of defective silicon in modern Integrated Circuits (ICs), designed in Deep Sub-micron (DSM) technologies, making it imperative to perform delay fault testing in these ICs. However, DSM ICs, also suffer from limited controllability and observability, which impedes easy and efficient testing for such ICs. In this paper, we present a novel Design for Testability (DFT) scheme to enhance controllability for delay fault testing. Existing DFT techniques for delay fault testing either have very high overhead, or increase the complexity of test generation significantly. The DFT technique presented in this paper, exploits the characteristics of CMOS circuit family and reduces the problem of delay fault testing of scan based sequential static CMOS circuits to delay fault testing of combinational circuits with complete access to all inputs. The scheme has low overhead, and also provides significant reduction in power dissipation during scan operation.
Joint Parameters Estimation for General Alpha Stable Random Noise
Authors: Xujie Li, Lianwen Jin, Xutao Li
Venue: Proceedings of the 2008 Congress on Image and Signal Processing, Vol. 5 - Volume 05 (2008)

This paper is concerned with the parameters estimation of i.i.d. random noise subjects to general Alpha stable distribution (αS) (include symmetrical and skewed distribution). We discuss the joint parameters estimation scheme for the αS random series. We firstly estimate the parameter α and σ by means of the Empirical Character Function (ECF) method. Using the deskewed transform, we next propose a new method to estimate the location parameter μ. Then, using the estimations of μ and α and with the Fractional Lower Order Moment (FLOM) method, an improved estimator of skewness parameter β is proposed. Furthermore, with the estimations of β and μ in the case of α=1 employing ECF method, a hybrid joint estimation scheme of four parameters is presented. The simulation results show that the proposed method performs well on wide region of α in estimating β and μ in comparison with traditional ECF method.

They are a part of the global history of data handling and computation. This paper describes the logical-numerical system expressed through these multicolored spatial arrays of knotted cords. included are basic ideas about the logical structures of some quipu formats and the means of encoding quantitative and nonquantitative data. Several specific examples are given of quipus containing arithmetic and logical relationships.
Assessment of an introductory database course: a case study
Authors: Edward P. Holden
Venue: Proceedings of the 9th ACM SIGITE conference on Information technology education (2008)

The Information Technology Department of the Golisano College of Computing and Information Sciences at Rochester Institute of Technology uses program assessment activities to guide curricular decisions which increase the quality of our programs. The assessment process routinely measures student success at achieving program objectives and consequently feeds the results back into the curriculum design process. Core competencies for each degree program are stated as behaviorally-based objectives. When it is determined that students overall are not achieving a specified criterion level for any given objective, these data are fed back to a curriculum design team where changes are made to improve student performance. Specifically, this paper will document the assessment plan developed in 2006 for an introductory database and data modeling course and the subsequent assessment. The assessment indicated an area that did not meet our established expectations for student success. Improvements were made to the course as a result of this assessment. This paper will illustrate the use of class exercises and examination questions to evaluate student success in achieving specified objectives. Results from the 2008 course assessment will be discussed.
Background Separation in Motion Picture Using Presumptive Eyes Position and Different Image
Authors: Se-Young Jang, Hoon-Sung Kwak
Venue: Proceedings of the international conference on Computational Science and Its Applications, Part II (2008)

The paper used the method using the information of colors by converting RGB information, the color image information to HSI model and YCbCr model and the presumptive eyes position, as the detection method of the region of face and its minutiae. From the sample image, the study suggested the method to separate and extract a subject from its background even in the sample images where there are colors similar to a given skin colors and to replace the original background with another background. Then, by using the only 4.8% of the overall region, the initial region of interest to comprehend filtering and a moving object was created, which demonstrates that based on the overall region, the only 13% may be used to track an actually moving object.

Speeding Up Feature Subset Selection Through Mutual Information Relevance Filtering
Authors: Gert Dijck, Marc M. Hulle
Venue: Proceedings of the 11th European conference on Principles and Practice of Knowledge Discovery in Databases (2007)

A relevance filter is proposed which removes features based on the mutual information between class labels and features. It is proven that both feature independence and class conditional feature independence are required for the filter to be statistically optimal. This could be shown by establishing a relationship with the conditional relative entropy framework for feature selection. Removing features at various significance levels as a preprocessing step to sequential forward search leads to a huge increase in speed, without a decrease in classification accuracy. These results are shown based on experiments with 5 high-dimensional publicly available gene expression data sets.
ePortfolios: A New Peer Assessment Technology in Educational Context
Authors: Youmei Wang
Venue: Proceedings of the 2008 International Symposiums on Information Processing (2008)

Peer-assessment has become more popular in the instructional assessment area. Portfolios were used as an important tool to facilitate computer-mediated peer assessment in online instruction. This study adopted quantitative approaches to explore the focus and attitude of onymous or anonymous peer-assessment with WePS (Web-based ePortfolios System) in Chinese context. Findings showed that Onymous group members paid attention to the response of their learning peers, that the onymous group had more confidence in peer-assessing and they thought that their assessment was more effective than anonymous groups, and that Onymous groups members recognized peer’s assessment on their learning more than the anonymous one. Compared with the related studies in western context this finding is different in some aspects.
A comparison of finite element formulations for dynamics of viscoelastic beams
Authors: Attila Pálfalvi
Venue: Finite Elements in Analysis and Design (2008)

Linear viscoelasticity has been used for a long time in structural analysis of time-dependent materials. For finite elements, it can be described using the internal variable formulation and the 'anelastic displacement field' (ADF) method. In this paper, two variants of the method are developed and tested on numerical examples. Based on the experiences, a slightly modified version of the original ADF method is suggested for use with linear viscoelasticity.
Cellphone Accessible Information Via Bluetooth Beaconing for the Visually Impaired
Authors: S. Bohonos, A. Lee, A. Malik, C. Thai, R. Manduchi
Venue: Proceedings of the 11th international conference on Computers Helping People with Special Needs (2008)

We describe a complete hardware/software system, dubbed Universal Real-Time Navigational Assistance (URNA), which enables communication of relevant location-aware information to a blind person carrying a Bluetooth-enabled cell phone. Although URNA can be used for a number of different applications (e.g., an information kiosk at a shopping mall or public transit information at a bus stop), we concentrate on the challenging case of an urban intersection. Information provided to the user as he or she approaches the intersection includes a description of the intersection topology and real-time notification of the state of the traffic lights.
Quality-Aware Probing of Uncertain Data with Resource Constraints
Authors: Jinchuan Chen, Reynold Cheng
Venue: Proceedings of the 20th international conference on Scientific and Statistical Database Management (2008)

In applications like sensor network monitoring and location-based services, due to limited network bandwidth and battery power, a system cannot always acquire accurate and fresh data from the external environment. To capture data errors in these environments, recent researches have proposed to model uncertainty as a probability distribution function (pdf), as well as the notion of probabilistic queries, which provide statistical guarantees on answer correctness. In this paper, we present an entropy-based metric to quantify the degree of ambiguity of probabilistic query answers due to data uncertainty. Based on this metric, we develop a new method to improve the query answer quality. The main idea of this method is to acquire (or probe) data from a selected set of sensing devices, in order to reduce data uncertainty and improve the quality of a query answer. Given that a query is assigned a limited number of probing resources, we investigate how the quality of a query answer can attain an optimal improvement. To improve the efficiency of our solution, we further present heuristics which achieve near-to-optimal quality improvement. We generalize our solution to handle multiple queries. An experimental simulation over a realistic dataset is performed to validate our approaches.
Iteration Disambiguation for Parallelism Identification in Time-Sliced Applications
Authors: Shane Ryoo, Christopher I. Rodrigues, Wen-Mei W. Hwu
Venue: Languages and Compilers for Parallel Computing: 20th International Workshop, LCPC 2007, Urbana, IL, USA, October 11-13, 2007, Revised Selected Papers (2007)

Media and scientific simulation applications have a large amount of parallelism that can be exploited in contemporary multi-core microprocessors. However, traditional pointer and array analysis techniques often fall short in automatically identifying this parallelism. This is due to the allocation and referencing patterns of time-slicing algorithms, where information flows from one time slice to the next. In these, an object is allocated within a loop and written to, with source data obtained from objects created in previous iterations of the loop. The objects are typically allocated at the same static call site through the same call chain in the call graph, making them indistinguishable by traditional heap-sensitive analysis techniques that use call chains to distinguish heap objects. As a result, the compiler cannot separate the source and destination objects within each time slice of the algorithm. In this work we discuss an analysis that quickly identifies these objects through a partially flow-sensitive technique called iteration disambiguation. This is done through a relatively simple aging mechanism. We show that this analysis can distinguish objects allocated in different time slices across a wide range of benchmark applications within tens of seconds even for complete media applications. We will also discuss the obstacles to automatically identifying the remaining parallelism in studied applications and propose methods to address them.
Robust Parameter Decision-Making Based on Multidisciplinary Knowledge Model
Authors: Jie Hu, Yinghong Peng, Guangleng Xiong
Venue: Proceedings of the 4th international conference on Modeling Decisions for Artificial Intelligence (2007)

This paper presents an approach of multidisciplinary knowledge modeling and robust parameter decision-making. Firstly, a multidisciplinary knowledge model is established. Secondly, a multidisciplinary decision-making algorithm is presented to solve the model. Finally, the method is demonstrated by a design example, in which knowledge in mechanics, cybernetics and dynamics are addressed. The results prove that multidisciplinary knowledge modeling is feasible, and the proposed method can be applied in multidisciplinary parameter decision-making process.
Managing emergent information systems: Towards understanding how public information systems come into being
Authors: Peter Groenewegen, Pieter Wagenaar
Venue: Information Polity (2006)

The introduction of information technology is often considered to be important for increased organisational performance. Yet, in the public sector, regularly promised results do not (fully) materialise, and the actual systems delivered deviate strongly from those intended. In the literature, two perspectives are used to explain these outcomes: infighting in the initial phases of an information system's life, and continuous adaptation of the technology during its use. These perspectives are based on the awareness that mutual structuration between social and technical elements is a core finding in the analysis of system development. This awareness, however, has been translated into only one dominant paradigm for system development. In this article we argue that structuration leads to different means of intervention. In the initial infighting perspective the main concern with regard to influencing the information system is one of the inclusion of stakeholders and user groups in system design. These recommendations have to a greater or lesser extent found their way into systems development and design. Yet, the initial infighting perspective leaves the question unanswered as to whether, in the long run, information systems remain stable or whether ongoing changes and re-invention determine the way systems work out. Obviously, if the latter holds true, identifying the sources of change and monitoring the direction of actions in the workplace during the entire life of an information system are a necessary addition to the inclusion of stakeholders in its initial phase. In this paper we apply both perspectives to empirical material on the introduction of the information system 'GMS' in emergency rooms in the Netherlands. By doing so we try to establish which perspective should be applied and under what circumstances, and thus what path to intervention should be chosen.
S-Web: An Efficient and Self-organizing Wireless Sensor Network Model
Authors: Hanh Le, Doan Hoang, Ravi Poliah
Venue: Proceedings of the 2nd international conference on Network-Based Information Systems (2008)

One of the major weaknesses of existing centralized algorithms in Wireless Sensor Network (WSN) routing is that sensor nodes are required to report their status (e.g. remaining energy level) to the central node (i.e. the Base Station ---BS) and receive configuration information from the BS (e.g. next hop routing). As a result, the WSNs suffer from high communication and/or computation overheads at sensor nodes to accommodate topology changes in the WSN. This paper proposes a novel scheme, called a Sensor Web (or S-Web), that organizes sensors into clusters based on their geographical location without requiring the sensors to have a Global Positioning System or actively locate themselves. The S-Web enables nodes to route data packets while consuming low energy in a decentralized manner. The model is self-organizing and distributed without the need of global network knowledge.
Conversion of PDEs to certain universal and easily handleable forms via space extension
Authors: Sevda Üsküplü, Metin Demiralp
Venue: Proceedings of the 1st WSEAS International Conference on Multivariate Analysis and its Application in Science and Engineering (2008)

In this paper it is focused on the conversion of partial differential equations to certain universal forms whose series solutions can be constructed via two term recursions. In order to obtain a universal form the space extension concept is used. The equation is converted into a new form by increasing the number of unknowns in such a way that the resulting equation is obtained in a vector valued form. This procedure is called as space extension approach. The new universal form which is the main goal of this work permits us to get its solution via series whose coefficients satisfy two term recursions. However, we do not give this procedure here in details since we consider the application of space extension concept as the most important aspect of the work. Instead, certain clues about the solution technique construction are also presented.

This paper reports a new finding on functionalities of trembling, the bodily manifestation of fear and joy. We consider trembling of a physically-simulated agent consisting of a vision system and a neural system. It is demonstrated that the noise to visual streams generated by trembling enhances signal to noise ratio of the neural system.
Experience report: visualizing data through functional pipelines
Authors: David J. Duke, Rita Borgo, Colin Runciman, Malcolm Wallace
Venue: ACM SIGPLAN Notices (2008)

Scientific visualization is the transformation of data into images. The pipeline model is a widely-used implementation strategy. This term refers not only to linear chains of processing stages, but more generally to demand-driven networks of components. Apparent parallels with functional programming are more than superficial: e.g. some pipelines support streams of data, and a limited form of lazy evaluation. Yet almost all visualization systems are implemented in imperative languages. We challenge this position. Using Haskell, we have reconstructed several fundamental visualization techniques, with encouraging results both in terms of novel insight and performance. In this paper we set the context for our modest rebellion, report some of our results, and reflect on the lessons that we have learned.
