Media Crate: tangible live media production interface
Authors: Tom Bartindale, Jonathan Hook, Patrick Olivier
Venue: Proceedings of the 3rd International Conference on Tangible and Embedded Interaction (2009)

Live media production -- the presentation of audio-visual content at events such as conferences and concerts -- is a high intensity task where a small production team must interact with an amalgamation of separate hardware tools to transform and direct a variety of media sources to outputs such as large screens, preview monitors, and web-casts. We present Media Crate, a tangible tabletop interface crafted in response to the key actions and needs of live media producers. Using tangibles, previously complex and ambiguous actions can now become collaborative and easy to learn, whilst providing expressive features not present in traditional interfaces. In this paper we give a description of the Media Crate's interface, discuss how knowledge and experience of live media production impacts on the design, and finally present the results of an initial deployment of the system at a live event.
Automatic Discovery of Coarse-Grained Parallelism in Media Applications
Authors: Shane Ryoo, Sain-Zee Ueng, Christopher I. Rodrigues, Robert E. Kidd, Matthew I. Frank, Wen-Mei W. Hwu
Venue: Transactions on High-Performance Embedded Architectures and Compilers I (2007)

With the increasing use of multi-core microprocessors and hardware accelerators in embedded media processing systems, there is an increasing need to discover coarse-grained parallelism in media applications written in C and C++. Common versions of these codes use a pointer-heavy, sequential programming model to implement algorithms with high levels of inherent parallelism. The lack of automated tools capable of discovering this parallelism has hampered the productivity of parallel programmers and application-specific hardware designers, as well as inhibited the development of automatic parallelizing compilers. Automatic discovery is challenging due to shifts in the prevalent programming languages, scalability problems of analysis techniques, and the lack of experimental research in combining the numerous analyses necessary to achieve a clear view of the relations among memory accesses in complex programs. This paper is based on a coherent prototype system designed to automatically find multiple levels of coarse-grained parallelism. It visits several of the key analyses that are necessary to discover parallelism in contemporary media applications, distinguishing those that perform satisfactorily at this time from those that do not yet have practical, scalable solutions. We show that, contrary to common belief, a compiler with a strong, synergistic portfolio of modern analysis capabilities can automatically discover a very substantial amount of coarse-grained parallelism in complex media applications such as an MPEG-4 encoder. These results suggest that an automatic coarse-grained parallelism discovery tool can be built to greatly enhance the software and hardware development processes of future embedded media processing systems.
Numerical study of segregation using multiscale models
Authors: Jin Sun Heng Xiao, Donghong Gao
Venue: International Journal of Computational Fluid Dynamics (2009)

Segregation occurs ubiquitously and is an important process in mineral processing. Numerical simulation of the segregation phenomena can improve the understanding of the mechanisms and hence helps the optimisation of equipment and process designs. In this article, a multi-fluid model and a hybrid model are presented. Their capabilities of addressing various aspects of segregation problems in gas-solid flows are demonstrated. Specifically, the multi-fluid model treats both particles and fluid at the macroscopic continuum level. It can be employed to simulate segregation, given different particle types are treated as different solid phases. The hybrid model is derived using a concurrent multiscale modelling approach, where the discrete element method for solid particles is coupled with continuum fluid mechanics for the fluid phase. It is demonstrated to be able to capture segregation, which may be difficult to be predicted by the current multi-fluid model in some cases.
3D Head Pose Estimation using Color Information
Authors: Qian Chen, Tetsuo Shimada, Haiyuan Wu, Tadayosi Shioyama
Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

This paper presents a new method to estimate the 3D pose of human heads in a single image. In contrast with other approaches, this method only uses color information about the skin region and the hair region of a head. We use an efficient algorithm based on perceptually uniform color system and fuzzy theory to extract the skin region and the hair region, and to detect faces in images. After that, some geometrical properties such as the area, the center, and the axis of least inertia of the skin region and the hair region are calculated, which are then used to estimate the 3D pose of the head.
Guessers for Finite-State Transducer Lexicons
Authors: Krister Lindén
Venue: Proceedings of the 10th International Conference on Computational Linguistics and Intelligent Text Processing (2009)

Language software applications encounter new words, e.g., acronyms, technical terminology, names or compounds of such words. In order to add new words to a lexicon, we need to indicate their inflectional paradigm. We present a new generally applicable method for creating an entry generator, i.e. a paradigm guesser, for finite-state transducer lexicons. As a guesser tends to produce numerous suggestions, it is important that the correct suggestions be among the first few candidates. We prove some formal properties of the method and evaluate it on Finnish, English and Swedish full-scale transducer lexicons. We use the open-source Helsinki Finite-State Technology [1] to create finite-state transducer lexicons from existing lexical resources and automatically derive guessers for unknown words. The method has a recall of 82-87 % and a precision of 71-76 % for the three test languages. The model needs no external corpus and can therefore serve as a baseline.

Application generators at IBM
Authors: Aaron M. Goodman
Venue: Proceedings of the June 7-10, 1982, national computer conference (1982)

This paper discusses the reasons for the great interest in application generation. Because of the growing backlog of user demands on data processing, a new technology with an order-of-magnitude increase in productivity is suggested. IBM has two families of application generation products. One, DMS, operates in a CICS/VS environment; the other, IMSADF, operates in an IMS/VS environment. An overview of the techniques involved and the benefits of using these systems is discussed.
Design principles of an office specification language
Authors: Michael Hammer, Jay S. Kunin
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

Office automation, interpreted most generally, is the utilization of technology to improve the productivity and quality of office work. This concept encompasses a wide range of devices, technologies, tools, and systems. One of its most powerful instances is the notion of an automated office information system. This is a software-intensive, computer-based system that seeks to support (and where appropriate, to automate) an entire office procedure, rather than simply to improve the performance of individual office tasks. However, there is a major impediment to the realization of such systems: because of their application-oriented and office-specific character, they are extremely costly to construct. One of the major reasons for this cost is that office systems analysts lack any tools or methodologies to employ in the process of determining and expressing the requirements of an automated office system. An office specification language is used to describe in a natural yet precise fashion the operation of an office system; its use can improve the process of constructing the system in a number of ways. In this paper, we set forth an approach to the design of office specification languages and present an overview of the major concepts in OSL, one such language that we are developing.
Projected interfaces: enabling serendipitous interaction with smart tangible objects
Authors: David Molyneaux, Hans Gellersen
Venue: Proceedings of the 3rd International Conference on Tangible and Embedded Interaction (2009)

The Projected Interfaces architecture enables bi-directional user interaction with smart tangible objects. Smart objects function as both input and output devices simultaneously by cooperating with projector-camera systems to achieve a projected display on their surfaces. Tangible manipulation of the object and camera-based tracking allow interaction directly with the projected display. Such hybrid interfaces benefit both from the flexibility offered by the GUI and the intuitiveness of TUI. In this paper we present the theory behind how to consider interaction for projected interfaces with an architecture design and a proof of concept implementation using an augmented photograph album.
A Quality Model for Evaluating Reusability of Services in SOA
Authors: Si Won Choi, Soo Dong Kim
Venue: Proceedings of the 2008 10th IEEE Conference on E-Commerce Technology and the Fifth IEEE Conference on Enterprise Computing, E-Commerce and E-Services (2008)

Service-Oriented Architecture (SOA) is an effective paradigm for publishing common features as services and reusing the published services in building applications. Therefore, reusability of services is a key criterion for evaluating the quality of services. The evaluation target for reusability in our model is the service, applied to both atomic and composite service. Reusability models for conventional paradigms such as OOP and CBD cannot effectively be applied to services in SOA. Hence, there is a high demand for devising a quality model to evaluate service reusability. In this paper, we propose a comprehensive quality model for evaluating reusability of services.
Noise analysis and synthesis for 3D laser depth scanners
Authors: Xianfang Sun, Paul L. Rosin, Ralph R. Martin, Frank C. Langbein
Venue: Graphical Models (2009)

This paper analyses the noise present in range data measured by a Konica Minolta Vivid 910 scanner, in order to better characterise real scanner noise. Methods for denoising 3D mesh data have often assumed the noise to be Gaussian, and independently distributed at each mesh point. We show via measurements of an accurately machined almost planar test surface that real scanner data does not have such properties: the errors are not quite Gaussian, and more importantly, exhibit significant short range correlation. We use this to give a simple model for generating noise with similar characteristics. We also consider how noise varies with such factors as laser intensity, orientation of the surface, and distance from the scanner. Finally, we evaluate the performance of three typical mesh denoising algorithms using real and synthetic test data, and suggest that new denoising algorithms are required for effective removal of real noise.
Internet traffic behavior profiling for network security monitoring
Authors: Kuai Xu, Zhi-Li Zhang, Supratik Bhattacharyya
Venue: IEEE/ACM Transactions on Networking (TON) (2008)

Recent spates of cyber-attacks and frequent emergence of applications affecting Internet traffic dynamics have made it imperative to develop effective techniques that can extract, and make sense of, significant communication patterns from Internet traffic data for use in network operations and security management. In this paper, we present a general methodology for building comprehensive behavior profiles of Internet backbone traffic in terms of communication patterns of end-hosts and services. Relying on data mining and entropy-based techniques, the methodology consists of significant cluster extraction, automatic behavior classification and structural modeling for in-depth interpretive analyses. We validate the methodology using data sets from the core of the Internet.

Authors: Kristien Michoel
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

EXE Extranet Education is an R&D project of a consortium of ten European partners built around the partnership of three local administrations (Bologna, London Islington and Barcelona) with a longstanding commitment to new technologies and citizen access. The project is co-financed by the European Commission after the Joint Call for Projects in the field of Educational Multimedia (December 1996). The objective of the project is to develop a multimedia toolkit to help teachers from across the educational spectrum to introduce new technologies in their daily didactic activities. EXE will provide the teachers with an Extranet which brings them in contact with colleagues in their city and in other parts of Europe. On the Extranet, teachers will find easy-to-use tools to develop their own course material: Educational Wizards for the design of lessons and didactic modules and a syllabus definition method for course development.
Extraction of Smooth and Thin Ridgelines from Fingerprint Images Using Geometric Prediction
Authors: Sanghati Ghosh, Partha Bhowmick
Venue: Proceedings of the 2009 Seventh International Conference on Advances in Pattern Recognition (2009)

Ridgelines play a vital role in a modern fingerprint identification system.However, due to inherent limitations in a fingerprint acquisition device,detection of ridgelines from an acquired image becomes a challenging task.Hence, several methodologies have been suggested over the years to detect ridgelines in a gray-scale fingerprint image, most of which produce thick ridgelines requiring subsequent thinning and smoothing in order to obtain the thinned ridge topography.Proposed in this paper is an efficient algorithm of extracting ridgelines from gray-scale fingerprint image using geometric prediction based on an efficient carry-forward mechanism of the knowledge acquired while traversing along the concerned ridgeline.Such a geometric tracing finally produces a ridge segment that is simultaneously smooth and thin, wherein lies the novelty of the algorithm.The algorithm is robust, efficient, and has minimal dependence on shareholding.On testing with benchmark databases, it is found to produce the desired output in terms of both runtime and quality.
Efficient uncoordinated FHSS anti-jamming communication
Authors: Mario Strasser, Christina Pöpper, Srdjan Čapkun
Venue: Proceedings of the tenth ACM international symposium on Mobile ad hoc networking and computing (2009)

We address the problem of jamming-resistant communication in scenarios in which the communicating parties do not share secret keys. This includes scenarios where the communicating parties are not known in advance or where not all parties can be trusted (e.g., jamming-resistant key establishment or anti-jamming broadcast to a large set of unknown receivers). In these cases, the deployment of shared secret keys is unrealistic, and therefore this problem cannot be solved using existing anti-jamming solutions like FHSS and DSSS that depend on pre-shared keys. Recently, a solution to this problem has been proposed that introduces Uncoordinated Frequency Hopping (UFH), a new spread-spectrum anti-jamming technique that does not rely on secret keys. In this work, we investigate the efficiency of UFH-based communication: we identify optimal strategies for the UFH frequency channel selection and we propose a set of new UFH-based anti-jamming schemes that, compared to the original UFH proposal, reduce the communication latency up to one-half (i.e., increase UFH communication throughput up to two times).

Architecture Specification of Multimedia Software Systems
Authors: Jeffrey J. P. Tsai, Kuang Xu
Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

Despite the growing importance of multimedia applications, we still know relatively little about how to specify, design and maintain this class of complex applications in a systematic manner.The concept of software architecture has recently emerged as a new way to improve our ability to effectively construct and maintain large-scale complex software systems. Under this new paradigm, software engineers are able to do evolutionary design of complex systems through architecture specification, design rationale capture, architecture validation and verification, and architecture transformation.Several architecture description languages (ADLs), such as Wright, Rapide, UniCon, ACME, etc. have been proposed to support the architecture development under this new software paradigm. Although current ADLs more or less support certain features of object-oriented design approach, few of them is purely based on object-oriented paradigm. In this paper, an architecture description language --- OOADL will be presented as a formal approach for the architecture level system design of multimedia software systems.This language takes object-oriented paradigm as its backbone, and provides formal semantics for modeling architectures of software systems. It also aims at some other goals such as support for hierarchical refinement, support for reuse of architecture styles, support for analysis and support for exception handling.We also introduce the default architecture style which brings the features of extensibility and reusability into the language. Finally, we use OOADL to construct part of the architecture framework of a multimedia system to illustrate the usage and modeling capability of OOADL.
Circuit theory of paralleling switching converters
Authors: Yuehui Huang, Chi K. Tse
Venue: International Journal of Circuit Theory and Applications (2009)

This paper studies the various paralleling styles for dc&ndash;dc switching converters from a circuit theoretic viewpoint. The study begins with a systematic classification of the types of parallel-connected dc&ndash;dc converters. In the classification, converters are modeled as current sources or voltage sources. From Kirchhoff's laws, the possible connection styles for paralleling current sources and voltage sources are derived, leading to the identification of three types of configurations for paralleling dc&ndash;dc converters. Then, control arrangements are classified according to the presence of current-sharing and voltage-regulation loops. Moreover, detailed operating principles with and without a current-sharing loop for the three basic paralleling connections to obtain both current sharing and voltage regulation are given. Applying small-signal analysis to the practical circuits, the inherent characteristics of each scheme are expounded. The roles of the current-sharing loop and origins of current-sharing errors are highlighted. Characteristics for all the schemes are obtained in terms of their performances in current sharing and voltage regulation. Finally, an experiment prototype is built to validate the analysis. The results clearly show the properties of the various paralleling schemes. Copyright &copy; 2008 John Wiley & Sons, Ltd.
Asset reliability modeling and simulation
Authors: Ted T. Tower
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Traditionally in manufacturing discrete event simulation, delay occurrence and duration are represented by static distributions. For many problems and industries, this assumption may be appropriate, rendering them essentially independent. The manufacturing of soft, disposable consumer products, however, may involve the assembly of multi-component products with flexible materials that pose significant challenges to process reliability and thus make the independence assumption invalid. In fact, these non-linear interactions between coupled-delays can result in substantial financial opportunities from seemingly minor contributors. We describe an Asset Reliability Modeling and Simulation (ARMS) framework developed at Kimberly-Clark that uses discrete event simulation and dynamic reliability modeling of assets' process event databases. Models are essentially built "on the fly" and survival simulations are validated against asset process history. Analytics and reports provide a means for identifying the biggest, overall improvement opportunities in performance metrics including production, delays, uptime, and waste.

Under the given conditions, we show that the corresponding statistics are asymptotically stationary and the law of large numbers hold for frequencies of the stock prices falling out normal scope of these technical analysis indexes under AR-ARCH, and give the rate of convergence in the case of nonstationary initial values, which give a mathematical rationale for these methods of technical analysis in supervising the security trends.
Bandwidth management and disposition for heterogeneous wireless network
Authors: Ying-Hong Wang, Hui-Min Huang, Chieh-Hsin Kuo
Venue: Proceedings of the 5th conference on Applied electromagnetics, wireless and optical communications (2007)

The integration of heterogeneous networks is a trend of Fourth Generation (4G) systems. But with more integrating network technologies, bandwidth management is more complicated. This paper proposes a bandwidth management method, called Bandwidth Management and Disposition (BMD). The BMD calculates the Reword Point (RP) to quantify the Mobile Host's (MH) requests, and calculates the Upgrade Order (UO) or Degrade Order (DO) to quantify the upgraded or downgraded sequence of bandwidth, respectively. In the future, when a new service type or network technology is created, the proposed system functions also can be directly applied. This paper analyzes the BMD is more feasible than the other existed methods. The simulation results also demonstrate the functionality of the BMD.
