Emotion Recognition and Synthesis System on Speech
Authors: Tsuyoshi Moriyama, Shinji Ozawa
Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

In this study, the system that is capable of both recognizing and synthesizing emotional content in speech is developed. At first, the relation information that relates the physical features of emotional speech to the emotional content perceived by listeners is estimated through linear statistical methods, and it is applied to the system. It realizes emotion recognition and synthesis just through easy linear operation using the relation information. In the system, the pitch contour is expressed by the model proposed by Fujisaki (7 parameters) and the power envelope is approximated by 5 line segments (11 parameters), and PSOLA is applied to synthesize the speech. The emotion words among which there is very little correlates were selected from the preliminary statistical experiments. The relation information was verified to be significant and from the result of the experiments, the system was able to recognize and synthesize emotional content in speech as subjects did.
The flexible console: FLEXICON
Authors: David L. Steinberg
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

Mature engineering fields have well-developed tools and standards which aid in development and guarantee product quality. Ironically, after over thirty years, programming remains basically an undisciplined processs with most software engineers still using techniques and tools which have changed little over the last ten years. There is as yet no common standard for programming tools and common experience in the use of those tools and techniques which currently do exist. The mounting cost of software dictates that the time has come to offer the software engineer tools which can increase his productivity, via saving time and making man-machine interaction more efficient.
Optimal design of tunable parametric wavelength converters based on degenerated four-wave mixing in optical fibers
Authors: Sheng Cui, Deming Liu, Feng Tu
Venue: Proceedings of the 2008 International Conference on Advanced Infocomm Technology (2008)

With the emergency of the dispersion flatten HNL-DSF and PCF, the one-pump parametric wavelength converter (PWC) based on degenerate four wave mixing in optical fibers becomes more and more attractive, owing to its low cost, simple structure and wide tunablity. In this paper it is proved that using a media fiber with appropriate zero dispersion wavelength, the tuning range of the one-pump PWC can be maximized. The maximal tuning range is proportional to the cube root of the product of the pump power and fiber nonlinear coefficient.
At the foundations of information justice
Authors: Matthew P. Butcher
Venue: Ethics and Information Technology (2009)

Is there such a thing as information justice? In this paper, I argue that the current state of the information economy, particularly as it regards information and computing technology (ICT), is unjust, conferring power disproportionately on the information-wealthy at great expense to the information-poor. As ICT becomes the primary method for accessing and manipulating information, it ought to be treated as a foundational layer of the information economy. I argue that by maximizing the liberties (freedom to use, freedom to distribute, freedom to modify, and so on) associated with certain computer software, an incentives-rich and stable environment can be established in ICT that will foster development of the information economy among the information poor. I suggest that the now-mature Free and Open Source Software paradigm, which has already produced widely-used enterprise-class applications, can be harnessed in support of these ends.
High Performance Computing and the Progress of Weather and Climate Forecasting
Authors: Philippe Bougeault
Venue: High Performance Computing for Computational Science - VECPAR 2008: 8th International Conference, Toulouse, France, June 24-27, 2008. Revised Selected Papers (2008)

Over the last few years, global weather forecasts from a number of operational numerical weather prediction centres have continued to progress steadily in skill and reach an impressive level of quality. The drivers of progress are increased resolution, better numerical algorithms, massive amounts of new observations from satellites, and very advanced data assimilation schemes to ingest observations in models. All of these aspects rely heavily on the ever increasing computing resources that have become available. The first part of the talk will describe some aspects of these improvements and will give considerations on how much each type of improvement has actually contributed to the overall improvement in forecast skill.While the most advanced weather forecasting models have reached global horizontal resolutions of about 20km, climate models are rather ranging from 300km to 100km. Recent research points to the need to increase the resolution of climate models to benefit from the same large improvements as the weather forecast models have undergone. In fact the concept of seamless weather and climate forecasts is rapidly developing. The second part of the talk will focus on this concept.The third part of the talk will highlight current difficulties in developing highly scalable systems, based on the ECMWF example. The ECMWF high performance computer system consists of 2 IBM POWER5+ Cluster 1600 supercomputer systems. Each cluster is made up of 155 compute nodes, plus a further 10 nodes which are used for I/O and networking. Each node consists of 8 Dual-core Power5+ processors, ie 16 physical cores, which have a clock frequency of 1.9 GHz., a peak performance of 7.6 Gflops/core and a sustained performance of 1 Gflop/core. Simultaneous Multi-Threading (SMT) means that each physical core can run 2 threads concurrently. So with SMT switched on, each node can be considered to have 32 logical cores. Users specify jobs by the number of MPI processes and the number of OpenMP threads. I will show examples of work to improve the scalability of various parts of our forecasting system on this machine.

NNexus: an automatic linker for collaborative web-based corpora
Authors: James Gardner, Aaron Krowne, Li Xiong
Venue: Proceedings of the 12th International Conference on Extending Database Technology: Advances in Database Technology (2009)

Collaborative online encyclopedias or knowledge bases such as Wikipedia and PlanetMath are becoming increasingly popular. We demonstrate NNexus, a generalization of the automatic linking engine of PlanetMath.org and the first system that automates the process of linking disparate "encyclopedia" entries into a fully-connected conceptual network. The main challenges of this problem space include: 1) linking quality (correctly identifying which terms to link and which entry to link to with minimal effort on the part of users), 2) efficiency and scalability, and 3) generalization to multiple knowledge bases and web-based information environment. We present NNexus that utilizes subject classification and other metadata to address these challenges and demonstrate its effectiveness and efficiency through multiple real world corpora.
Exploiting Shift Invariance to Obtain a High Payload in Digital Image Watermarking
Authors: Maurice Maes, Ton Kalker, Jaap Haitsma, Geert Depovere
Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

Robust, invisible watermarking of digital images or video very often has to satisfy a set of mutually conflicting requirements. These requirements include invisibility, robustness to image processing and geometric transformations, low false positive probabilities, high payload, fast detection and embedding, etc. In this paper we show how invariance to translations can be exploited to increase the payload.This is achieved by simultaneous embedding of several shifted watermark patterns, such that the information content is hidden in the relative shifts of the patterns. The principles of this are illustrated for the case of JAWS, a spatial domain watermark method developed by Philips. The method can easily be applied to other watermark methods which are able to detect shifted versions of watermarks.
Study on Evolutionarily Stable Strategies (ESS) in SME Clusters
Authors: Enping Shen, Zuobing Fan
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

Evolutionarily stable strategies (ESS) is used between species co-exist in small medium enterprise (SME) clusters. We assume that each of the potential helpers knows the others’ strategies in cluster in this paper. We show that the ability to observe their realizations influences the Evolutionarily Stable Strategies (ESS) of the game. According to our results, under the partial information structure ESS do not always exist. No assistance and immediate assistance are possible ESS, while delayed assistance cannot be an ESS. This paper considers a symmetric conflict, all the potential helpers have the same strategy sets and they all play the same role. A general game theoretical model is developed under one information structures: partial information. At the same time we apply our model to study of the assistance in SME clusters.
Randomized Algorithms for Buffer Management with 2-Bounded Delay
Authors: Marcin Bienkowski, Marek Chrobak, Łukasz Jeż
Venue: Approximation and Online Algorithms: 6th International Workshop, WAOA 2008, Karlsruhe, Germany, September 18-19, 2008. Revised Papers (2009)

In the problem of buffer management with bounded delay, packets with weights and deadlines arrive at a network switch over time, and the goal is to send those packets on the outgoing link while maximizing the total weight of the packets that are sent before their deadlines expire. In the 2-bounded delay case, each packet has to be sent either in the step of its release or in the next step. In the deterministic case, the optimal competitive ratio for this case is &phi;&thinsp;&asymp;&thinsp;1.618. In the randomized case, against oblivious adversaries, the optimal competitive ratio is 1.25. The only yet unresolved case is that of randomized algorithms against adaptive adversaries. For this case, we give a complete solution by proving that the optimal competitive ratio is 4/3. Additionally, we give a lower bound of 1.2 for the 2-uniform case.
Fast and noniterative scheduling in input-queued switches: Supporting QoS
Authors: Kevin F. Chen, Edwin H. -M. Sha, S. Q. Zheng
Venue: Computer Communications (2009)

We report three fast and scalable scheduling algorithms that provide exact bandwidth guarantee, low delay bound, and reasonable jitter in input-queued switches. The three schedulers find a maximum input/output matching in a single iteration. They sustain 100% throughput under both uniform and bursty traffic. They work many times faster than existing scheduling schemes and their speed does not degrade with increased switch size. SRA and SRA+ algorithms are of O(1) time complexity and can be implemented in simple hardware. SRA tends to incur different delays to flows of different classes of service due to their different subscribed portions of the total bandwidth. SRA+, a weighted version of SRA, operates on cells that arrive uniformly and on cells of packets such that the cells of whole packets are switched contiguously. SRA+ improves over SRA in that all flows undergo the same delays regardless of their bandwidth shares. The schedulers operate on queue groups at the crossbar arbiters in a distributed manner.
Simple and efficient implementation of discrete plates and shells
Authors: Max Wardetzky, Miklós Bergou, Akash Garg, David Harmon, Denis Zorin, Eitan Grinspun
Venue: ACM SIGGRAPH ASIA 2008 courses (2008)

Efficient computation of curvature-based energies is important for practical implementations of geometric modeling and physical simulation applications. Building on a simple geometric observation, we propose a hinge-based bending model that is simple to implement, efficient to compute, and offers a great number of effective material parameters. Our formulation builds on two mathematical observations: (a) the bending energy of a thin flexible plate (resp. shell) can be expressed as a quadratic (resp. cubic) polynomial of surface positions provided that the surface does not stretch; (b) a general class of anisotropic materials---those that are orthotropic---is captured by appropriate choice of a single stiffness per hinge. We provide two approaches for deriving our isometric bending model (IBM): a purely geometric view and a derivation based on finite elements. By offering a highly efficient treatment of force Jacobians, our model impacts the speed of a general range of surface animation applications, from isotropic cloth and thin plates, over orthotropic fracturing of thin shells, to Willmore-type surface fairing. The present notes are condensed from previous articles by the authors: [Bergou et al. 2006], [Garg et al. 2007], and [Wardetzky et al. 2007]---augmented by a finite element treatment that was not present in these earlier works.

Authors: Xiaolei Zhu, Sanroku Tsukamoto, Tadahiro Kuroda
Venue: Proceedings of the 2009 Asia and South Pacific Design Automation Conference (2009)

A dynamic offset control technique that employs charge compensation by timing control is proposed for comparator design in scaled CMOS technology. The analysis has been verified by fabricating a 65 nm CMOS 1.2 V 1 GHz comparator that occupies 25 x 65 &mu;m2 and consumes 380 &mu;W. Circuits for offset control occupies 21% of the areas and 12% of the power consumption of the whole comparator chip.

Venue: Biometrics and Identity Management: First European Workshop, BIOID 2008, Roskilde, Denmark, May 7-9, 2008. Revised Selected Papers (2008)

A new 3D face database that includes a rich set of expressions, systematic variation of poses and different types of occlusions is presented in this paper. This database is unique from three aspects: i) the facial expressions are composed of judiciously selected subset of Action Units as well as the six basic emotions, and many actors/actresses are incorporated to obtain more realistic expression data; ii) a rich set of head pose variations are available; and iii) different types of face occlusions are included. Hence, this new database can be a very valuable resource for development and evaluation of algorithms on face recognition under adverse conditions and facial expression analysis as well as for facial expression synthesis.
Symbolic program analysis using term rewriting and generalization
Authors: Nishant Sinha
Venue: Proceedings of the 2008 International Conference on Formal Methods in Computer-Aided Design (2008)

Symbolic execution [28] is a popular program verification technique, where the program inputs are initialized to unknown symbolic values, and then propagated along program paths with the help of decision procedures. This technique has two main bottlenecks: (a) the number of program execution paths to be explored may be exponential, and, (b) the state representation (map from variables to terms) may blow-up. We propose a new program verification technique that addresses the problems by (a) performing a work list based analysis that handles join points, and (b) simplifying the intermediate state representation by using term rewriting. In addition, our technique tries to compact expressions generated during analysis of program loops by using a term generalization technique based on anti-unification [40], [42]. We have implemented the proposed method in the F-Soft verification framework using the Maude term rewriting engine. Preliminary experiments show that the proposed method is effective in improving verification times on real-life benchmarks.

Authors: R. O. Al-Seedy, A. A. El-Sherbiny, S. A. El-Shehawy, S. I. Ammar
Venue: Computers Mathematics with Applications (2009)

This paper presents an analysis for the M/M/c queue with balking and reneging. It is assumed that arriving customers balk with a fixed probability and renege according to a negative exponential distribution. The generating function technique will be used to obtain the transient solution of system which results in a simple differential equation. Based on the properties of Bessel functions in the solution of this differential equation the probabilities can be extracted in a direct way.
High Resolution DOA Estimation Using Unwrapped Phase Information of MUSIC-Based Noise Subspace
Authors: Koichi Ichige, Kazuhiko Saito, Hiroyuki Arai
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

This paper presents a high resolution Direction-Of-Arrival (DOA) estimation method using unwrapped phase information of MUSIC-based noise subspace. Superresolution DOA estimation methods such as MUSIC, Root-MUSIC and ESPRIT methods are paid great attention because of their brilliant properties in estimating DOAs of incident signals. Those methods achieve high accuracy in estimating DOAs in a good propagation environment, but would fail to estimate DOAs in severe environments like low Signal-to-Noise Ratio (SNR), small number of snapshots, or when incident waves are coming from close angles. In MUSIC method, its spectrum is calculated based on the absolute value of the inner product between array response and noise eigenvectors, means that MUSIC employs only the amplitude characteristics and does not use any phase characteristics. Recalling that phase characteristics plays an important role in signal and image processing, we expect that DOA estimation accuracy could be further improved using phase information in addition to MUSIC spectrum. This paper develops a procedure to obtain an accurate spectrum for DOA estimation using unwrapped and differentiated phase information of MUSIC-based noise subspace. Performance of the proposed method is evaluated through computer simulation in comparison with some conventional estimation methods.
Determination of number of kanbans in a supply chain system via Memetic algorithm
Authors: M. Rabbani, J. Layegh, R. Mohammad Ebrahim
Venue: Advances in Engineering Software (2009)

In this research multi-stage supply chain system which is controlled by kanban system, is evaluated. In kanban system, decision making is based on determination of the number of kanbans as well as batch sizes. This paper attempts to model supply chain system with regard to costs under just-in-time (JIT) production philosophy. Since adopted model is of mixed integer non-linear programming (MINLP) type and solving it by exact algorithm such as branch and bound (B&B) takes a lot of time, a heuristic method via Memetic algorithm (MA) is presented. Some problems are solved by our proposed MA to illustrate its performance.
A 12-bit 3.7-Msample/s Pipelined A/D Converter Based on the Novel Capacitor Mismatch Calibration Technique
Authors: Shuaiqi Wang, Fule Li, Yasuaki Inoue
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

This paper proposes a 12-bit 3.7-MS/s pipelined A/D Converter based on the novel capacitor mismatch calibration technique. The conventional stage is improved to an algorithmic circuit involving charge summing, capacitors' exchange and charge redistribution, simply through introducing some extra switches into the analog circuit. This proposed ADC obtains the linearity beyond the accuracy of the capacitor match and verifies the validity of reducing the nonlinear error from the capacitor mismatch to the second order without additional power dissipation through the novel capacitor mismatch calibration technique. It is processed in 0.5 μm CMOS technology. The transistor-level simulation results show that 72.6 dB SNDR, 78.5 dB SFDR are obtained for a 2 V Vpp 159.144 kHz sine input sampled at 3.7 MS/s. The whole power dissipation of this ADC is 33.4 mW at the power supply of 5 V.
Supporting End Users to Be Co-designers of Their Tools

Venue: Proceedings of the 2nd International Symposium on End-User Development (2009)

Nowadays very different people use computer systems for their daily working activities, but also for fun and entertainment or only to satisfy their information needs. Designers are doing their best to create computer systems that work as end users expect, but it must be honestly admitted that they often fail and end users have all rights to complain. In order to improve this situation and create better systems, participatory approaches have been proposed, which involve end users in the design and development process. However, this solution is not without flaws, mainly because timing and ways of users' participation are very critical. In this paper we discuss our approach to create working systems, which is based on a star model of the software life cycle that drives system design, development and evolution, since software design and development is seen as an evolutive process, driven by end-users activities in the real life. System development does not end with its first release; it is experimented by its end users and further evolved on the basis of their feedbacks. End users are truly engaged in the software life cycle as co-designers and experimenters of the software tools they will use in various application domains.
