On-line prevention of wire breakage in wire electro-discharge machining
Authors: I. Cabanes, E. Portillo, M. Marcos, J. A. Sánchez
Venue: Robotics and Computer-Integrated Manufacturing (2008)

Wire electro-discharge machining (WEDM) is a fully extended and competitive machining process widely used to produce dies and moulds. However, the risk of wire breakage affects adversely the full potential of WEDM since the overall process efficiency is considerably reduced. The present paper discusses the results of the analyses of an exhaustive experimental database that reproduces unexpected disturbances that may appear during normal operation. The results of the analyses reveal new symptoms that allow one to predict wire breakage. These symptoms are especially related to the occurrence of an increase in discharge energy, peak current, as well as increases and/or decreases in ignition delay time. The differences observed in the symptoms related to workpiece thickness are also studied. Another contribution of this paper is the analyses of the distribution of the anticipation time for different validation tests. Based on the results of the analyses, this paper contributes to improve the process performance through a novel wire breakage monitoring and diagnosing system. It consists of two well differentiated parts: the virtual instrumentation system (VIS) that measures relevant magnitudes, and the diagnostic system (DS) that detects low quality cutting regimes and predicts wire breakage. It has been successfully validated through a considerable number of experimental tests performed on an industrial WEDM machine for different workpiece thickness. The efficiency of the supervision system has been quantified through an efficiency rate defined in this paper.
Tranquil interaction: exploring archaic culture in the Kyl&auml; installation
Authors: Tommi Ilmonen
Venue: Proceedings of the 2007 conference on Designing pleasurable products and interfaces (2007)

A group of people walks into a dark room. On the walls there are photographs of peasant life in Viena Carelia, taken in 1894. One of the people is carrying a candle in her hand. The flickering flame is the only source of light in the space. As she nears the first picture, a lullaby begins. After a while the group moves to the next picture. As they move the song changes by itself. This is Kyl&auml; --- an interactive installation that presents photographs and folk music from the 19th century Viena Carelia. The aim of the installation was to design a space that could create a rich experience of an archaic culture for the visitors. The installation is computer driven with novel candle-based interaction. This paper describes the design issues involved, two deployments of the installation, and how visitors have reacted to the system in the two contexts. Finally we elaborate on the style of the interaction--tranquil interaction.
Texture-based feature tracking for effective time-varying data visualization
Authors: Jesus Caban, Alark Joshi, Penny Rheingans
Venue: IEEE Transactions on Visualization and Computer Graphics (2007)

Analyzing, visualizing, and illustrating changes within time-varying volumetric data is challenging due to the dynamic changes occurring between timesteps. The changes and variations in computational fluid dynamic volumes and atmospheric 3D datasets do not follow any particular transformation. Features within the data move at different speeds and directions making the tracking and visualization of these features a difficult task. We introduce a texture-based feature tracking technique to overcome some of the current limitations found in the illustration and visualization of dynamic changes within time-varying volumetric data. Our texture-based technique tracks various features individually and then uses the tracked objects to better visualize structural changes.We show the effectiveness of our texture-based tracking technique with both synthetic and real world time-varying data. Furthermore, we highlight the specific visualization, annotation, registration, and feature isolation benefits of our technique. For instance, we show how our texture-based tracking can lead to insightful visualizations of time-varying data. Such visualizations, more than traditional visualization techniques, can assist domain scientists to explore and understand dynamic changes.
Concurrent Test Implementations
Authors: Shawn Molavi, Toby McPheeters
Venue: Proceedings of the 16th Asian Test Symposium (2007)

Today's large SOC devices include many different IP blocks which tested sequentially add significant test time to the production flow. Testing of several devices in parallel is one way to reduce test time and cost per device. However, as more functionality is added to the SOCs, the pin count will increase and limit the number of sites that can be tested in parallel.
"More like these": growing entity classes from seeds
Authors: Luis Sarmento, Valentin Jijkuon, Maarten de Rijke, Eugenio Oliveira
Venue: Proceedings of the sixteenth ACM conference on Conference on information and knowledge management (2007)

We present a corpus-based approach to the class expansion task. For a given set of seed entities we use co-occurrence statistics taken from a text collection to define a membership function that is used to rank candidate entities for inclusion in the set. We describe an evaluation framework that uses data from Wikipedia. The performance of our class extension method improves as the size of the text collection increases.
Acoustic speech unit segmentation for concatenative synthesis
Authors: H. M. Torres, J. A. Gurlekian
Venue: Computer Speech and Language (2008)

Synthesis by concatenation of natural speech improves perceptual results when phonemes and syllables are segmented at places where spectral variations are small [Klatt, D., 1987. Review of text-to-speech conversion for English. J. Acoust. Soc. Am 82 (3), 737-793]. An automatic segmentation method is explored here, using a tool based on a combination of Entropy Coding, Multiresolution Analysis, and Kohonen's Self Organized Maps. The segmentation method considers that there are no limits imposed by any linguistic unit. Resulting waveforms represent phone chains dominated by spectral dynamic structures. Each acoustic unit obtained could be composed of a variety of phonemes or a segmented part of them at the unit boundary. The number of units and unit structure are speaker dependent, i.e. rate, segmental and suprasegmental distinctive features affect them as dynamic structure varies. Results obtained from two databases - one male, one female - of 741 sentences each show this dependence, presenting a different number of units and occurrences for each speaker. Nevertheless, both speakers show a high occurrence of three (36-24%) and four (29-27%) phoneme sequences. Vowel-consonant-vowel sequences are the most frequent type (9.7-8.3%). Consonant-vowel syllables, which are phonemically frequent in Spanish (58%), are less represented (6.6-3.2%) using this method. The relevance of half phone segmentation is verified given that 66% for the female speaker and 53% for the male speaker, of the total units start and end with a segmented phone. Perceptual experiments showed that concatenated speech, created with dynamic acoustic units, was judged more natural than with diphone units.
Nonlinear Integration of Spatial and Temporal Forecasting by Support Vector Machines
Authors: Jiaqiu Wang, Tao Cheng, Xia Li
Venue: Proceedings of the Fourth International Conference on Fuzzy Systems and Knowledge Discovery - Volume 04 (2007)

Spatio-temporal data mining is the extraction of unknown and implicit knowledge, structures, spatio-temporal relationships, or patterns not explicitly stored in spatio-temporal databases. As one of data mining techniques, forecasting is widely used to predict the unknown future based upon the patterns hidden in the current and past data. In order to achieve spatio-temporal forecasting, some mature analysis tools, e.g., time series and spatial statistics are extended to the spatial dimension and the temporal dimension respectively, or they are combined linearly as spatio-temporal integration. However, such linear combination of spatial and temporal dimensions is just a simplification of complicated spatio-temporal associations existing in complex geographical phenomena. In this study, The Support Vector Machines is introduced to construct nonlinear combination functions related to the spatial and temporal dimensions for integrated spatio-temporal forecasting. The proposed method has been tested by forecasting the annual average temperature of meteorological stations in P R China. The forecasting result shows that nonlinearly integrated spatio-temporal forecasting model via Support Vector Machines obtained better forecasting accuracy than those obtained by linear combination and other conventional methods.

Authors: Peng Liu, Guojun Dai, Tingting Fu
Venue: Proceedings of the Eighth ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing - Volume 02 (2007)

Nowadays, remote control applications via the Internet are going to be used more and more widely with the development of powerful chips and network technology. For applications which do not need real-time communication or persistent connection and have a little amount of data transportation, conventional approaches based on Web services either are a little bit complex, or have a higher overhead. In this paper we introduce another method called WeeRMES, a Web services based email extension for remote monitoring of embedded systems, to be supplement of conventional remote control methods in some special occasions. Thanks to the model, we are able to do all those things using emails such as sending devices instructions, inspecting device status and gathering data using XML capsulated messages. User interfaces can be dynamically achieved by means of XForms generated by Java classes loaded on target devices. Furthermore, researches are carried out on security mechanism to ensure safety and robustness of the system. An idiographic implementation is given as an example in the end.
Special Feature: Semiconductor Memory Reliability with Error Detecting and Correcting Codes
Authors: L. Levine
Venue: Computer (1976)

Although continuing cost and performance improvements of the new bipolar and MOS RAM devices are providing strong incentives for their greatly expanded use in mainframe memory and other storage applications, these components have not yet reached the degree of reliability required for large memory systems. Fortunately, however, memory system organization is compatible with a wide variety of low-cost fault detection and correction techniques6,10,11 that go a long way toward compensating for otherwise error-prone systems.

Authors: Heon Gyu Lee, Ki Yong Noh, Hong Kyu Park, Keun Ho Ryu
Venue: Proceedings of the 7th IEEE International Conference on Computer and Information Technology (2007)

HRV (Heart Rate Variability) is one of the most promising quantitative indications of autonomic activity. In present study, our aim is to develop the multi-pararmetric feature including linear and nonlinear features of HRV. We also propose a suitable prediction model to enhance the reliability of medical examination for cardiovascular disease. This study analyzes the HRV for three recumbent positions. Interaction effect between recumbent positions and groups (Normal, Patient) was observed based on the HRV indices. We have carried out various experiments on linear and nonlinear features of HRV to evaluate classifiers. In our experiments, SVM and Bayesian classifiers outperformed the other classifiers.

Headers Overhead Estimation, Header Suppression and Header Compression in WiMAX
Authors: Loutfi Nuaymi, Nabil Bouida, Nabil Lahbil, Philippe Godlewski
Venue: Proceedings of the Third IEEE International Conference on Wireless and Mobile Computing, Networking and Communications (2007)

In this paper, we consider header suppression and header compression in WiMAX/ IEEE 802.16 BWA (Broadband Wireless Access) system. The data packet headers always carry some redundancy. In wireless systems such as WiMAX, it is important for radio resource use efficiency to reduce this redundancy. Both header suppression and then header compression have been defined for WiMAX. In this paper, we start by computing PHYsical and MAC (Medium Access Control) layers overhead. Then, we remind upper layers (IP, UDP and RTP) headers suppression and compression processes and evaluate their effect in the specific case of VoIP transmission. We propose application details for header suppression. We estimate and then compare the performance of header suppression and header compression in WiMAX. The paper ends by some interesting future topics of research.

Venue: Proceedings of the 1st international conference on Bio inspired models of network, information and computing systems (2006)

Molecular communication [1]-[2] is an emerging communication paradigm that uses molecules as a communication medium. Molecular communication allows biological and artificially created nano- or cell-scale devices to communicate with each other. In molecular communication, senders encode information onto molecules (called information molecules), and information molecules are then loaded onto carrier molecules and transported to a receiver. Upon arriving at a receiver, information molecules are unloaded from carrier molecules, and the receiver reacts biochemically to the information molecules. This paper proposes a molecular communication system that uses liposomes with gap junction proteins as an interface. A liposome acts as a container of information molecules, and information molecules propagate through gap junctions [3] from a sender to a liposome and also from a liposome to a receiver.
Organisational knowledge management system for e-learning practice in universities
Authors: Toshio Okamoto, Toshie Ninomiya
Venue: Proceedings of the sixth conference on IASTED International Conference Web-Based Education - Volume 2 (2007)

From 2004 to 2007, our university ran a three-year project called 'GP Project' as part of a national project named "Selected Efforts of the Distinctive University Education Support Program (Good Practice Project)", with the support of the Japanese Ministry of Education, Culture, Sports, Science and Technology. In this project, we are replacing more than 30 existing courses with e-Learning. The courses must be integrated seamlessly into the course grade information system currently in use in the educational affairs section. For this integration, we introduced a new Learning Management System, which is easy to customise. We developed a Learning Management System (LMS) by modifying a commercial LMS, WebClass, to which it is easy to add new functions. The first-phase system has been implemented and we are now preparing to integrate the course grade information into the LMS. This paper describes our current three-year university-wide project and then explains the functions of the newly developed LMS. This system supports registration, authoring and importing information from different sections of educational affairs. This allows effective pedagogical activities, including mentoring/coaching through utilising Digital Portfolio (e-Karte). This three-year project with the LMS has facilitated development of a method of organisational knowledge management and e-Pedagogy.
An Approach to Formal Definitions and Proofs of Programming Principles
Authors: J. Misra
Venue: IEEE Transactions on Software Engineering (1978)

A method for formal description of programming prinicples is presented in this paper. Programming principles, such as sequential search can be defined and proven even in the absence of an application. We represent a principle as a program scheme which has partially interpreted functions in it. The functions must obey certain input constraints. Use of these ideas in program proving is illustrated with examples.

Thermal Herding: Microarchitecture Techniques for Controlling Hotspots in High-Performance 3D-Integrated Processors
Authors: Kiran Puttaswamy, Gabriel H. Loh
Venue: Proceedings of the 2007 IEEE 13th International Symposium on High Performance Computer Architecture (2007)

3D integration technology greatly increases transistor density while providing faster on-chip communication. 3D implementations of processors can simultaneously provide both latency and power benefits due to reductions in critical wires. However, 3D stacking of active devices can potentially exacerbate existing thermal problems. In this work, we propose a family of Thermal Herding techniques that (1) reduces 3D power density and (2) locates a majority of the power on the top die closest to the heat sink. Our 3D/thermal-aware microarchitecture contributions include a significance-partitioned datapath that places the frequently switching 16-bits on the top die, a 3D-aware instruction scheduler allocation scheme, an address memoization approach for the load and store queues, a partial value encoding for the L1 data cache, and a branch target buffer that exploits a form of frequent partial value locality in target addresses. Compared to a conventional planar processor, our 3D processor achieves a 47.9% frequency increase which results in a 47.0% performance improvement (min 7%, max 77% on individual benchmarks), while simultaneously reducing total power by 20% (min 15%, max 30%). Without our Thermal Herding techniques, the worst case 3D temperature increases by 17 degrees. With our Thermal Herding techniques, the temperature increase is only 12 degrees (29% reduction in the 3D worst-case temperature increase).
Cybercrime Investigation Training and Specialist Education for the European Union
Authors: Paul Stephens, Abhaya Induruwa
Venue: Proceedings of the Second International Workshop on Digital Forensics and Incident Analysis (2007)

The first major piece of malicious software, the Morris worm, hit the Internet in November 1988. Since then the Internet has experienced an explosion of malware and virus attacks affecting individuals and organizations alike. More recently the world has seen concerted efforts by organized criminals to commit IT crimes on a global scale. In order to effectively deal with criminal activities such as identity theft leading to online fraud, law enforcement officers and criminal investigators of today require an entirely new skills set. As cybercrime comes of age the investigators find themselves working in territories without regard to geopolitical and socio-economic boundaries requiring cooperation and collaboration on a scale that has not existed before. The Falcone Programme and AGIS projects have recognized a strong need for collaboration within the European Union member states and have recommended the joint development and certification of training and education for cybercrime investigators and law enforcement officers. This paper reports on the state of these projects and looks at some of the innovative academic partnerships that have been developed to address the issue of Cybercrime Forensic Investigation Training and Specialist Education in the UK, and illustrate the impact that they have on European requirements as outlined by the Bologna Agreement and Europol initiatives.

Authors: M. L. Dertouzos, M. E. Kaliski, K. P. Polzen
Venue: IEEE Transactions on Computers (1969)

This paper is concerned with a general approach to the on-line simulation of block-diagram systems. These systems may be analog, digital, or hybrid; memory or memoryless; explicit or implicit (i.e., possessing loops of memoryless elements); vector or scalar; or of a more specialized nature, such as dynamic systems with integrators as memory elements; and simulation may be conducted in one or more dimensions, such as time and/or space.
