Analyzing Gait Using a Time-of-Flight Camera
Authors: Rasmus R. Jensen, Rasmus R. Paulsen, Rasmus Larsen
Venue: Proceedings of the 16th Scandinavian Conference on Image Analysis (2009)

An algorithm is created, which performs human gait analysis using spatial data and amplitude images from a Time-of-flight camera. For each frame in a sequence the camera supplies cartesian coordinates in space for every pixel. By using an articulated model the subject pose is estimated in the depth map in each frame. The pose estimation is based on likelihood, contrast in the amplitude image, smoothness and a shape prior used to solve a Markov random field. Based on the pose estimates, and the prior that movement is locally smooth, a sequential model is created, and a gait analysis is done on this model. The output data are: Speed, Cadence (steps per minute), Step length, Stride length (stride being two consecutive steps also known as a gait cycle), and Range of motion (angles of joints). The created system produces good output data of the described output parameters and requires no user interaction.

The effects of word prediction on communication rate for AAC
Authors: Keith Trnka, Debra Yarrington, John McCaw, Kathleen F. McCoy, Christopher Pennington
Venue: Human Language Technologies 2007: The Conference of the North American Chapter of the Association for Computational Linguistics; Companion Volume, Short Papers on XX (2007)

Individuals using an Augmentative and Alternative Communication (AAC) device communicate at less than 10% of the speed of "traditional" speech, creating a large communication gap. In this user study, we compare the communication rate of pseudo-impaired individuals using two different word prediction algorithms and a system without word prediction. Our results show that word prediction can increase AAC communication rate and that more accurate predictions significantly improve communication rate.
Physical Unclonable Functions and Secure Processors
Authors: Srini Devadas
Venue: Proceedings of the 11th International Workshop on Cryptographic Hardware and Embedded Systems (2009)

As computing devices become ever more pervasive, two contradictory trends are appearing. On one hand computing elements are becoming small, disseminated and unsupervised. On the other hand, the cost of security breaches is increasing as we place more responsibility on the devices that surround us. The result of these trends is that physical attacks present an increasing risk that must be dealt with.Physical Unclonable Functions (PUFs) are a tamper resistant way of establishing shared secrets with a physical device. They rely on the inevitable manufacturing variations between devices to produce an identity for a device. This identity is unclonable, and in some cases is even manufacturer resistant (i.e., it is impossible to produce devices that have the same identity).We describe a few applications of PUFs, including authentication of individual integrated circuits such as FPGAs and RFIDs, and the production of certificates that guarantee that a particular piece of software was executed on a trusted chip.We present the design and implementation of two PUF-enabled devices that have been built: a low-cost secure RFID that can be used in anti-counterfeiting and other authentication applications, and a secure processor capable of performing certified execution and higher-level cryptographic functions.The PUF-enabled RFID uses a simple challenge-response protocol for authentication that shifts complexity to the reader or server and therefore only requires a small number of transistors on the device side. The PUF-enabled processor generates its public/private key pair on power-up so its private key is never left exposed in (on-chip or off-chip) non-volatile storage. It is capable of a broad range of cryptographic functionality, including certified execution of programs. The ACM Portal is published by the Association for Computing Machinery.

DexterNet: An Open Platform for Heterogeneous Body Sensor Networks and its Applications
Authors: Philip Kuryloski, Annarita Giani, Roberta Giannantonio, Katherine Gilani, Raffaele Gravina, Ville-Pekka Seppa, Edmund Seto, Victor Shia, Curtis Wang, Posu Yan, Allen Y. Yang, Jari Hyttinen, Shankar Sastry, Stephen Wicker, Ruzena Bajcsy
Venue: Proceedings of the 2009 Sixth International Workshop on Wearable and Implantable Body Sensor Networks (2009)

We present an open-source platform for wireless body sensor networks called DexterNet. The system supports real-time, persistent human monitoring in both indoor and outdoor environments. The platform utilizes a three-layer architecture to control heterogeneous body sensors. The first layer called the body sensor layer (BSL) deals with design of heterogeneous body sensors and their instrumentation on the body. At the second layer called the personal network layer (PNL), the body sensors on a single subject communicate with a mobile base station, which supports Linux OS and the IEEE 802.15.4 protocol. The BSL and PNL functions are abstracted and implemented as an open-source software library, called Signal Processing In Node Environment (SPINE). A DexterNet network is scalable, and can be reconfigured on-the-fly via SPINE. At the third layer called the global network layer (GNL), multiple PNLs communicate with a remote Internet server to permanently log the sensor data and support higher-level applications. We demonstrate the versatility of the DexterNet platform via several real-world applications.

Authors: Y. L. Hou, C. H. Li, B. H. Lu
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

The surface quality, such as microscopic topography and tribological characteristics finished surface by abrasive jet with grinding wheel as restraint were evaluated and analyzed. Experiments were performed with plane grinder M7120 and workpiece material 40Cr steel. The machined surface morphology was studied using Scanning Electron Microscope (SEM) and microcosmic geometry parameters were measured with TALYSURF5 instrument respectively. According to the metrical results, the surface topographical characteristics were evaluated with power spectral density (PSD) about machined surface before and after finishing. The results show that longitudinal geometry parameter values of finished surface were diminished comparing with ground surface,and the mean ripple distance was decreased and, ripple and peak density were increased. The tribological characteristics of finished surface were also investigated with pin on disk wear tester of MG-2000 tester. The experimental results show that the friction coefficient and wear amounts of finishing machining surface were obviously decreased comparing with ground surface. As a result, life and precision consistency of finished workpiece were improved and the experimental result of tribological characteristics was agreement with PSD analysis.

In order to provide the news demands that a real-time database needs to work properly, some improvements have been proposed in aspects well done like concurrency control, scheduling and query language. In the perspective of obtain better results, despite the accomplished efforts, these problems continuous been studied. In this paper we introduce a new query language for real-time database (QL-RTDB), that's an extension of the structured query language (SQL-99). Besides the new functionalities of the extended language presented, we also show its implementation with the applied results obtained.

Venue: Proceedings of the 9th International Conference on Algorithms and Architectures for Parallel Processing (2009)

Multi-core processors are becoming prevalent rapidly in personal computing and embedded systems. Nevertheless, the programming environment for multi-core processor based systems is still quite immature and lacks efficient tools. In this work, we present a new VERTAF/Multi-Core framework and show how software code can be automatically generated from SysML models of multi-core embedded systems. We illustrate how model-driven design based on SysML can be seamlessly integrated with Intel's threading building blocks (TBB) and the Quantum Platform middleware. We use a digital video recording system to illustrate the benefits of the framework. Our experiments show how SysML/QF/TBB help in making the multi-core embedded system programming model-driven, easy, efficient, and effortless.
Developing interactive web applications with the Google Web Toolkit
Authors: Ryan McFall, Charles Cusack
Venue: Journal of Computing Sciences in Colleges (2009)

Web sites such as Gmail, Facebook and other Web 2.0 applications have changed the way that we think about web functionality. These sites behave more like desktop applications than traditional document-centric sites. Developing these interactive web applications using technologies such as AJAX is tedious, error prone and difficult to optimize. Development environments and tools for such applications lag behind the more mature tools available for languages such as Java. The Google Web Toolkit is an emerging technology that facilitates the integration of the powerful tools available for the Java platform into the interactive web world. The toolkit consists of tools that compile Java code into a combination of HTML and Javascript code; since the code is being written in Java, all of the tools available for Java development can be leveraged, such as the Eclipse IDE and testing tools such as JUnit. Utilizing a compiler to generate Javascript provides an opportunity for optimization that would be difficult without the use of the toolkit. In this workshop, participants will learn about the Google Web Toolkit, including the philosophy behind the toolkit, the GUI framework that it provides, and the methods available for interaction with remote services. Participants will be walked through the development of a simple "Stock Ticker" application that interacts with the Yahoo stock data service. Several other sample applications will be presented, including sample assignments given to students in a class focusing on applications of the GWT. An outline of the workshop is: &bull; Introduction to the Google Web Toolkit (30 minutes) &bull; Presentation and discussion of several applications built using the toolkit (30 minutes) &bull; Development of the Stock Ticker application (1 hour) &bull; Overview of the GUI Framework and server integration techniques (30 minutes) &bull; Overview of a course on the GWT (15 minutes) &bull; Questions/wrap up
A novel low-power full-adder cell with new technique in designing logical gates based on static CMOS inverter
Authors: K. Navi, V. Foroutan, M. Rahimi Azghadi, M. Maeen, M. Ebrahimpour, M. Kaveh, O. Kavehei
Venue: Microelectronics Journal (2009)

A new low-power full-adder based on CMOS inverter is presented. This full-adder is comprised of inverters. Universal gates such as NOR, NAND and MAJORITY-NOT gates are implemented with a set of inverters and non-conventional implementation of them. In the proposed design approach the time consuming XOR gates are eliminated. As full-adders are frequently employed in a tree-structured configuration for high-performance arithmetic circuits, a cascaded simulation structure is employed to evaluate the full-adders in a realistic application environment. The circuits being studied were optimized for energy efficiency using 0.18@mm and 90nm CMOS process technologies. The proposed full-adder shows full swing logic, balanced outputs and strong output drivability. It is also observed that the presented design can be utilized in many cases especially whenever the lowest possible power consumption is targeted. Circuits layout implementations and checking their functionality have been done using Cadence IC package and Synopsys HSpice, respectively.
An Improvement of Short 2-Secure Fingerprint Codes Strongly Avoiding False-Positive
Authors: Koji Nuida
Venue: Information Hiding: 11th International Workshop, IH 2009, Darmstadt, Germany, June 8-10, 2009, Revised Selected Papers (2009)

A 2-secure fingerprint code proposed by Nuida et al. (IEEE CCNC 2007) has very desirable characteristics that false-positive never occur under Marking Assumption against at most two pirates and that false-positive is very unlikely to occur even in the absence of these assumptions. However, its code length could be further reduced; in fact, another 2-secure code proposed in the same work has significantly shorter code length. In this article, we demonstrate how to mix those two codes to inherit both of their advantages. The resulting 2-secure codes have short lengths, and possess the above characteristics whenever the number of pirates (may exceed two but) is not too large.

Authors: Lei Yin, Xiaoxiang Liu, Weigang Jiang, Jianwen Xie
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

The creative ability index is quite important for enterprises. This paper proposes an evaluation method for enterprise innovation ability based on rough set theory. Firstly, an index reduction which effects the enterprises based on the rough set theory is carried out, then the major indexes of enterprise development ability is extracted. Secondly, the standardized processing of all kinds of index values based on the membership function makes them have a unified dimension thus possessing comparability. Thirdly, a comprehensive evaluation of enterprise creative ability via the principal component analysis is performed. Finally, we obtain the creative ability level of that enterprise compared with other ones by using its concrete statistical data to prove its effectiveness.
A TCAM-based solution for integrated traffic anomaly detection and policy filtering
Authors: Zhijun Wang, Hao Che, Jiannong Cao, Jingshan Wang
Venue: Computer Communications (2009)

The survivability of the future Internet is largely dependent on whether it will be able to successfully address both security and performance issues facing the Internet. On one hand, the Internet becomes more and more vulnerable due to fast spreading malicious attacks. On the other hand, it is under great stress to meet ever growing/changing application demands while having to sustain multi-gigabit forwarding performance. In this paper, we propose a Ternary Content Addressable Memory (TCAM) coprocessor based solution for high speed, integrated TCP flow anomaly detection and policy filtering. The attacking packets with spoofed source IP addresses are detected through two-dimensional (2D) matching. The key features of the solution are: (1) setting flag bits in TCAM action code to support various packet treatments; (2) managing TCP flow state in pair to do 2D matching. We evaluate the solution's ability to detect TCP-based flooding attacks based on real-world-trace simulations. The results show that the proposed solution can match up OC-192 line rate. The possible modifications of the solution for the detection of low rate TCP-targeted attacks are also discussed.
Integrating Lecture Recordings with Social Networks
Authors: Patrick Fox, Johannes Emden, Nicolas Neubauer, Oliver Vornberger
Venue: Proceedings of the 2009 First International Conference on Advances in Multimedia (2009)

This paper describes an approach to integrate lecture recordings, based on the virtPresenter framework, within social networks. A lot of social networks have recently begun to provide application programming interfaces (APIs) for external applications, allowing access to users’ proﬁle information and their friendship relations. The project “social virtPresenter” combines the resulting social graph with the existing lecture recordings. Thus, “social virtPresenter” provides a basis for a new collaborative multimedia learning process.
Data clustering with a relational push-pull model
Authors: Adam Anthony, Marie DesJardins
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 2 (2007)

Relational data clustering is the task of grouping data objects together when both attributes and relations between objects are present. We present a new generative model for relational data in which relations between objects can have either a binding or separating effect.
Message Authentication Codes from Unpredictable Block Ciphers
Authors: Yevgeniy Dodis, John Steinberger
Venue: Proceedings of the 29th Annual International Cryptology Conference on Advances in Cryptology (2009)

We design an efficient mode of operation on block ciphers, SS-NMAC. Our mode has the following properties, when instantiated with a block cipher f to yield a variable-length, keyed hash function H: (1) MAC Preservation. H is a secure message authentication code (MAC) with birthday security, as long as f is unpredictable. (2) PRF Preservation. H is a secure pseudorandom function (PRF) with birthday security, as long as f is pseudorandom. (3) Security against Side-Channels. As long as the block cipher f does not leak side-channel information about its internals to the attacker, properties (1) and (2) hold even if the remaining implementation of H is completely leaky. In particular, if the attacker can learn the transcript of all block cipher calls and other auxiliary information needed to implement our mode of operation. Our mode is the first to satisfy the MAC preservation property (1) with birthday security, solving the main open problem of Dodis et al. [7] from Eurocrypt 2008. Combined with the PRF preservation (2), our mode provides a hedge against the case when the block cipher f is more secure as a MAC than as a PRF: if it is false, as we hope, we get a secure variable-length PRF; however, even if true, we still "salvage" a secure MAC, which might be enough for a given application.We also remark that no prior mode of operation offered birthday security against side channel attacks, even if the block cipher was assumed pseudorandom.Although very efficient, our mode is three times slower than many of the prior modes, such as CBC, which do not enjoy properties (1) and (3). Thus, our work motivates further research to understand the gap between unpredictability and pseudorandomness of the existing block ciphers, such as AES.
Learning to interpret utterances using dialogue history
Authors: David DeVault, Matthew Stone
Venue: Proceedings of the 12th Conference of the European Chapter of the Association for Computational Linguistics (2009)

We describe a methodology for learning a disambiguation model for deep pragmatic interpretations in the context of situated task-oriented dialogue. The system accumulates training examples for ambiguity resolution by tracking the fates of alternative interpretations across dialogue, including subsequent clarificatory episodes initiated by the system itself. We illustrate with a case study building maximum entropy models over abductive interpretations in a referential communication task. The resulting model correctly resolves 81% of ambiguities left unresolved by an initial handcrafted baseline. A key innovation is that our method draws exclusively on a system's own skills and experience and requires no human annotation.
Experiments with Automatic Query Formulation in the Extended Boolean Model
Authors: Lucie Skorkovská, Pavel Ircing
Venue: Proceedings of the 12th International Conference on Text, Speech and Dialogue (2009)

This paper concentrates on experiments with automatic creation of queries from natural language topics, suitable for use in the Extended Boolean information retrieval system. Because of the lack and/or inadequacy of the available methods, we propose a new method, based on pairing terms into a binary tree structure. The results of this method are compared with the results achieved by our implementation of the known method proposed by Salton and also with the results obtained with manually created queries. All experiments were performed on the same collection that was used in the CLEF 2007 campaign.
