Fair Delay Optimization-based Resource Allocation Algorithm for Video Traffic over Wireless Multimedia System
Authors: M. R. Rizk, M. I. Dessouky, Sami A. El-Dolil, Mohammed Abd-Elnaby
Venue: Wireless Personal Communications: An International Journal (2009)

The major issue related to the realization of wireless multimedia system is the design of suitable medium access control (MAC) protocol. The design challenge is to maximize the utilization of the limited wireless resources while guaranteeing the various quality of service requirements for all traffic classes especially for the stringent real-time constraint of real time variable bit rate (rt-VBR) video service. In this paper a novel resource allocation algorithm for video traffic is proposed. The proposed allocation algorithm aims to provide fair delay for video packets by minimizing the delay difference among transmitted video packets. At the same time it adaptively controls the allocated resources (bandwidth) for video traffic around the corresponding average bit rate, and has the ability of controlling the quality of service (QoS) offered for video traffic in terms of packet loss probability and average delay. A minimized control overhead of only two bits is needed to increase the utilization efficiency. Simulation results show that the proposed algorithm achieves very high utilization and provides nearly fair delay among video packets. Its efficiency is also investigated under traffic integration condition with voice and data traffic to show that the QoS offered to video traffic does not change in the presence of the highest priority voice traffic while data traffic increases the channel utilization to 98% by using the remaining bandwidth after voice and video traffic while a good QoS is offered to voice and data traffic.
Economic power dispatch of power system with emission controlled using particle swarm optimization
Authors: Yee Ming Chen, Wen-Shiang Wang
Venue: Proceedings of the 8th conference on Systems theory and scientific computation (2008)

Operating at absolute minimum cost can no longer be the only criterion for dispatching electric power due to increasing concern the environmental consideration. The emission controlled economic dispatch (ECED) problem which accounts for minimization of both fuel cost and emission is a multiple objective function problem. This paper proposed the particle swarm optimisation (PSO) metaheuristic method to minimise the total fuel cost of generation and environmental pollution caused by fossil based thermal generating units and also maintain an acceptable system performance in terms of limits on generator real and reactive power outputs, bus voltages, and power flow of transmission lines in areas. Simulation results on the IEEE 30-bus network with three generators and four areas show that by this method, an optimum solution can be given quickly.
Concurrent and Local Evaluation of Normal Programs
Authors: Rui Marques, Terrance Swift
Venue: Proceedings of the 24th International Conference on Logic Programming (2008)

Tabled evaluations can incorporate a number of features, including tabled negation, reduction with respect to the well-founded model, tabled constraints and answer subsumption. Many of these features are most efficiently evaluated using the Local evaluation strategy, which fully evaluates each mutually dependent set of tabled subgoals before returning answers to other subgoals outside of that set. In this paper, we introduce a formalism, Concurrent Local SLG by which multiple threads of computation concurrently perform Local evaluation of the well-founded semantics, and which is a framework for multi-threaded tabling in the XSB system. We prove several properties of Local evaluation within single-threaded tabled computation. We then extend SLG to a model of concurrency and show that the completeness and complexity of SLG are retained when computed by multiple threads. Finally, we extend Local evaluation to concurrent SLG, and show that the properties of Local evaluation continue to hold under concurrency.
The Fourth Order Cumulant-Based MUSIC Algorithm for Harmonic Retrieval in Colored Noise
Authors: Hou Chu-lin, Wang De-shi
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 02 (2009)

The MUSIC algorithm is well known for its high resolution capability and various aspects of its statistical performance have been investigated. In this paper, a general fourth order cumulant matrix which conforms with the structure of MUSIC algorithm is introduced. Because the fourth order cumulant is insensitive to Gaussian noise, The MUSIC-type method can be reformulated using the fourth-order cumulant matrices instead of autocorrelation matrices when additive noise is colored Gaussian. By doing so, the additive colored Gaussian noise can be suppressed. So fourth order cumulant-based MUSIC algorithm provides better resolution and estimation performance when noise is color. Firstly,the theory of MUSIC algorithm is studied; additionally,the relation between fourth order cumulant and autocorrelation function is analyzed. Simulation results demonstrate the effectiveness of the cumulant-based MUSIC algorithm, and it can restrain effectively the effect of coloured noise comparing with its equivalent second-order statistics-based version. Moreover, it has higher resolution probability and low SNR scenario in direction of arrival estimation.
Linking computer science, art, and practice through digital sound
Authors: Jennifer Burg, Jason Romney
Venue: Proceedings of the 40th ACM technical symposium on Computer science education (2009)

This paper reports on an NSF-grant supported summer workshop that brought music and computer science students together for eight weeks to explore creative projects in digital sound production. The dynamics of the students' collaborations were observed as they crafted experimental projects weaving together music, theatre production, sampled digital audio, and MIDI. Moving among various levels of abstraction, the students found practical and artistic motivations to learn the science of digital sound. The projects they produced suggest ways to revitalize computer science courses by linking science, art, and practice through digital sound, a subject naturally interesting to students.
Unscented Transform for SLAM Using Gaussian Mixture Model with Particle Filter
Authors: Liang Zhang, Xujiong Meng, Yaowu Chen
Venue: Proceedings of the 2009 International Conference on Electronic Computer Technology (2009)

The aims of the Simultaneous Localization and Mapping (SLAM) in a real-world environment is to obtain faster processing speed, more precise predictable results, and better system approximation and consistency. This paper proposes a combination of the Gaussian Mixture Model (GMM) with Particle Filter (PF) and Unscented Kalman Filter (UKF) for the robot SLAM. Also, the PF Markov Chain Monte Carlo (MCMC)method is applied to get a better particle distribution. The application of the SLAM process will depend on the incoming measurement data; whether there is a landmark signal being detected or not. In the former condition, the new landmark position computing, the GMM updating and, the robot and the landmark position updating are needed and, in the latter case,robot and landmark position are predicted through a prediction equation. From the experimental results, it can be seen that the processing speed and the precision of the proposed method are better than that of the FAST SLAM and the UKF SLAM,especially in a dense map environment.
To burst or circuit switch?
Authors: Andrew Zalesky
Venue: IEEE/ACM Transactions on Networking (TON) (2009)

We develop, analyze and then numerically compare performance models of a fast-adapting and centrally controlled form of optical circuit switching (OCS) with a conservative form of optical burst switching (OBS). For the first time, we consider a unified model comprising both: edge buffers at which arriving packets are aggregated and enqueued according to a vacation-type service discipline with nondeterministic set-up times, together with a core network comprising switches arbitrarily interconnected via fibers to allow transmission of packets from an edge buffer to their desired egress point through use of a dynamic signaling process to establish a lightpath, and in the case of OCS, also acknowledge its establishment. As such, edge buffers dynamically issue requests for wavelength capacity via a two or one-way reservation signaling process. Previously analyzed models of OCS and OBS have either been for a stand-alone edge buffer or a core network without edge buffering. We compare OCS with OBS in terms of packet blocking probability due to edge buffer overflow and blocking at switches in the case of OBS; mean packet queueing delay at edge buffers; and, wavelength capacity utilization. Also for the first time, we derive the exact blocking probability for a multi-hop stand-alone OBS route, assuming Kleinrock's independence, which is not simply a matter of summing the stationary distribution of an appropriate Markov process over all blocking states, as shown to be the case for an OCS route.

Engineering practice often has to deal with complex systems of multiple variable and multiple parameter models almost always with strong non-linear coupling. The conventional analytical techniques-based approaches for describing and predicting the behaviour of such systems in many cases are doomed to failure from the outset, even in the phase of the construction of a more or less appropriate mathematical model. These approaches normally are too categorical in the sense that in the name of modelling accuracy they try to describe all the structural details of the real physical system to be modelled. This can significantly increase the intricacy of the model and may result in a enormous computational burden without achieving considerable improvement of the solution. The best paradigm exemplifying this situation may be the classic perturbation theory: the less significant the achievable correction, the more work has to be invested to obtain it. A further important component of machine intelligence is a kind of structural uniformity giving room and possibility to model arbitrary particular details a priori not specified and unknown. This idea is similar to the ready-to-wear industry, which introduced products, which can be slightly modified later on in contrast to tailor-made creations aiming at maximum accuracy from the beginning. These subsequent corrections can be carried out by machines automatically. This learning ability is a key element of machine intelligence. The past decade confirmed that the view of typical components of the present soft computing as fuzzy logic, neural computing, evolutionary computation and probabilistic reasoning are of complementary nature and that the best results can be applied by their combined application. Today, the two complementary branches of Machine Intelligence, that is, Artificial Intelligence and Computational Intelligence serve as the basis of Intelligent Engineering Systems. The huge number of scientific results published in Journal and conference proceedings worldwide substantiates this statement. The present book contains several articles taking different viewpoints in the field of intelligent systems.
Wooden Geometric Puzzles: Design and Hardness Proofs
Authors: Helmut Alt, Hans Bodlaender, Marc van Kreveld, G&#x00fc;nter Rote, Gerard Tel
Venue: Theory of Computing Systems (2009)

We discuss some new geometric puzzles and the complexity of their extension to arbitrary sizes. For gate puzzles and two-layer puzzles we prove NP-completeness of solving them. Not only the solution of puzzles leads to interesting questions, but also puzzle design gives rise to interesting theoretical questions. This leads to the search for instances of partition that use only integers and are uniquely solvable. We show that instances of polynomial size exist with this property. This result also holds for partition into k subsets with the same sum: We construct instances of n integers with subset sum O(n k+1), for fixed&#x00a0;k.
Tail asymptotics for the queue size distribution in a discrete-time Geo/G/1 retrial queue
Authors: Bara Kim, Jeongsim Kim
Venue: Queueing Systems: Theory and Applications (2009)

We consider a discrete-time Geo/G/1 retrial queue where the service time distribution has a finite exponential moment. We show that the tail of the queue size distribution is asymptotically geometric. Remarkably, the result is inconsistent with the corresponding result in the continuous-time counterpart, the M/G/1 retrial queue, where the tail of the queue size distribution is asymptotically given by a geometric function multiplied by a power function.
TaNx thin films as copper barriers sputter-deposited at various NH3-to-Ar flow ratios
Authors: Jem Kun Chen, Chia-Hao Chan, Shiao-Wei Kuo, Feng-Chih Chang
Venue: Microelectronic Engineering (2009)

To optimize the performance of copper diffusion barriers, we deposited TaN"x thin films through radio frequency (RF) sputtering at various flow ratios of the reactive gases NH"3 and Ar. The composition of the film changed from Ta"2N to TaN, as evidenced from deposition rates and N-to-Ta ratios, when we increased the NH"3-to-Ar flow ratio from 0.075 to 0.3. Furthermore, the structure of the TaN"x thin film transformed from body-centered cubic (BCC) to face-centered cubic (FCC) to nanocrystalline upon increasing the NH"3-to-Ar flow rate, as revealed by the three steps in the rate of formation of the TaN"x films during the sputtering process. When incorporated in Cu/TaN"x/n^+np^+ diodes, the thermal stability of the TaN"x thin film-measured in terms of the leakage current remaining below 3@mA-increased from 450 to 550^oC upon increasing the NH"3-to-Ar flow ratio from 0.075 to 0.3. It appears that the NH"3-to-Ar flow ratio influences the properties of TaN"x films predominantly through modification of the crystal structure.

Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

Effective use of digital video can be greatly improved by a combination of two technologies: computer vision for automated video analysis and information visualization for data visualization. The unstructured, spatio-temporal nature of video poses tough challenges in the extraction of semantics using fully automated techniques. In the CueVideo project, we combine these automated technologies together with a user interface designed for rapid filtering and comprehension of video content. Our interface introduces two new techniques for viewing video and builds upon existing techniques to provide synergistic views of the video content. We also report on a preliminary user study that compares the efficacy of these views in providing comprehension of video content.

Venue: IEEE Internet Computing (2009)

Service integration is an important issue in service-oriented computing. As an infrastructure for service-oriented architectures, the enterprise service bus (ESB) has been regarded as a promising way to support dynamic and agile service integration in distributed heterogeneous environments. The authors' ESB framework for large-scale service integration, JTangSynergy, adopts several mechanisms for providing effective and efficient dependability. It enables automated recovery from component failures and robust execution of composite services by checking service compatibility. The authors tested JTangSynergy in the Chinese Healthcare Service Integration project.

Robust Noise Suppression Algorithm with the Kalman Filter Theory for White and Colored Disturbance
Authors: Nari Tanabe, Toshihiro Furukawa, Shigeo Tsujii
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

We propose a noise suppression algorithm with the Kalman filter theory. The algorithm aims to achieve robust noise suppression for the additive white and colored disturbance from the canonical state space models with (i) a state equation composed of the speech signal and (ii) an observation equation composed of the speech signal and additive noise. The remarkable features of the proposed algorithm are (1) applied to adaptive white and colored noises where the additive colored noise uses babble noise, (2) realization of high performance noise suppression without sacrificing high quality of the speech signal despite simple noise suppression using only the Kalman filter algorithm, while many conventional methods based on the Kalman filter theory usually perform the noise suppression using the parameter estimation algorithm of AR (auto-regressive) system and the Kalman filter algorithm. We show the effectiveness of the proposed method, which utilizes the Kalman filter theory for the proposed canonical state space model with the colored driving source, using numerical results and subjective evaluation results.

Plant protection is one of the most important applications in agricultural domain. An agricultural Expert system Generic Tool (AESGT) [1] has been developed for rapid generation of plant protection expert system. AESGT provides generic knowledge modeling approaches namely: CommonKADS[2] and Generic Tasks[3], but This tool doesn't have an explanation facility, which is an important component in any expert system (ES), as is used to clarify the reasoning process to the users and hence improve the understandability and acceptability of the expert system. This paper describes our experience in augmenting the AESGT tool with "How" and "Why Asking" explanation components for different kind of knowledge representation schemes that the AESGT tool is using. The developed explanation components can deal with different knowledge representation schemes that are commonly used by the modeling approaches mentioned above (e.g., tables, structured tables, hierarchy, constraints and rules), and handle the task level explanation. As well, our explanation components have been successfully implemented and used to augment a real agricultural expert system with different kind of explanations.

Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

Advances in electronics have brought the promise of wearable computers to near reality. Such systems can offer a highly personal and mobile information and communication infrastructure. Previous research has investigated where wearable computers can be located on the human body - critical for successful development and acceptance. However, for a location to be truly useful, it needs to not only be accessible for interaction, socially acceptable, comfortable and sufficiently stable for electronics, but also effective at conveying information. In this paper, we describe the results from a study that evaluated reaction time performance to visual stimuli at seven different body locations. Results indicate that there are numerous and statistically significant differences in the reaction time performance characteristics of these locations. We believe our findings can be used to inform the design and placement of future wearable computing applications and systems.
