In this paper, we propose the first chemical-mechanical polishing (CMP) aware application-specific three-dimensional (3D) network-on-chip (NoC) design that minimizes through-silicon-via (TSV) height variation, thus reduces its bonding failure, and meanwhile optimizes conventional NoC design objectives. Our 3D NoC design assigns cores to proper silicon layers, determines the 3D NoC topology, allocates routing paths, and then floorplans cores, routers and TSV arrays by a CMP-aware manner. The key idea behind this 3D NoC design flow is to determine the CMP-aware 3D NoC topology where TSV arrays with low and uniform metal density are inserted between adjacent layers. Experimental results show that our CMP-aware 3D NoC design can achieves lower TSV height variation, higher performance and lower power consumption than the previous state-of-the-art 3D NoC designs.

Runtime testing is a common way to detect faults during normal system operation. To achieve a specific diagnostic coverage runtime testing is also used in safety critical, automotive embedded systems. In this paper we propose a test architecture to consolidate the hardware resource consumption and timing needs of runtime tests and of application and system tasks in a hard real-time embedded system as applied to the automotive domain. Special emphasis is put to timing requirements of embedded systems with respect to hard real-time and concurrent hardware resource accesses of runtime tests and tasks running on the target system.

Emergence of Web 2.0 technologies became a trigger for a revolution that goes far beyond the Web. For an average student Web was transformed from a steady, accessible source of information into a place of action and viable exchange of knowledge - a kind of a virtual classroom. Students started to look for experience and a touch to reality online, and this is where remote laboratories come in place. Such laboratories became an inevitable need in electrical and computer engineering courses dealing with microcomputers. This paper presents an overview of available architectures of microcomputer laboratories used today and addresses their most important limitations. Moreover, an important extension of such architecture is proposed allowing support for remote Wireless Sensor Network (WSN) laboratory. Different aspects of compatibility between microcomputer laboratories and WSNs have been examined to allow creation of an general extension model. With additional effort and adaptation, WSN nodes may serve remote clients as an economic and accessible microcomputer laboratory providing invaluable hands-on experience and a motivation for a course using it.

Verification of web service protocols by logic of knowledge

Web services is a popular distributed systems technology and its effectiveness and efficiency rely badly on the underlying protocols. And web service protocols are designed in XML formats so the message structures within are quite different from the conventional ones. Therefore, the well-established formal verification techniques for conventional protocols, which have gained substantial achievements in practice, cannot be applied directly to them because of the inherently different syntax. In this paper, we propose a justification-oriented and automatic formal approach to verify, in the standard Dolev-Yao model, concerned security properties expressed as epistemic notions, i. e., logic of knowledge, for web service protocols, based on a fault-preserving mapping tool called SuD (SOAP under Dolev-Yao). Our approach is significant because, instead of finding flaws in finite number of protocol sessions, the specifications we are to verify can hold in arbitrary number of sessions. © 2011 Binary Information Press.

A passive universal image steganalysis method is proposed that is shown to be of higher detection accuracy than existing truly blind steganalysis methods including Farid's and the WAM. This is achieved by improving some weaknesses of Farid's steganalysis scheme in feature extraction, that is, instead of deriving an over-determined equation system for each sub band of the wavelet decomposition, the sub bands are divided into overlapping blocks and an over-determined equation system is constructed for each block. To guarantee the existence of finite answers, the over-determined equation systems are solved in a way different from Farid's by using Moore-Penrose pseudo-inverse concept. Further improvement to the performance is achieved by adding diagonal directions and increasing the number of moments. The comparative evaluations confirm the superiority of the proposed method over prevalent blind steganalysis schemes.

This paper presents a unified control method for the combined permanent magnet generator (PMG) and three-phase boost rectifier that can be used in autonomous power systems such as more-electric aircraft requiring high power density. With the unified control, the paper shows the system can function well without additional boost inductors. The design procedure for the control is presented, including current loops, voltage loop, reactive power loop and rotor position estimator loop. Simulation and experimental results show that both the DC link voltage and reactive power could be controlled effectively. In addition, the paper proposes a method to optimize the overall system efficiency by appropriate reactive power distribution. The power density and efficiency of the PMG and rectifier system is improved with the unified control.

The paper analyzed and model of a fault tolerant electromechanical controlled worm gear driven fuel shut off valve for aerospace application. The analysis is mainly on design a reduced order fractional controller. This is for controlling the velocity of worm gear so that the friction torque due to uneven rotational speed can be avoided. Because with the friction and stiction and backlash the valve system performance is reduced and more and more unstable this leads the system to failure. The proposed controller can provide robustness against the uncertain loading torque and system parameter.

In this paper, a valid frequency range of throat signal analyses is presented. Compare to speech signals, the throat signals have many differences in the amount of information. In this context, targeting on throat signals to find valid frequency range is one of the most important analyses for the development of new breed of feature extraction algorithm. In this respect, using analysis similarity of throat signals feature distribution and correlation analysis of throat signals in the frequency domain, the frequency range can be found with effective and quick response time to be applied to a voice command recognition system using neck-microphone. As a result, the proposed frequency range is from 200Hz (center frequency) to 2001Hz (center frequency). For the neck-microphone voice command system using the proposed frequency range, a significant reduction in time complexity of 25% can be achieved without any loss in recognition rate.

Rotor angle of the machine may accelerate or decelerate due to transient instability depending on the mechanical power or the turbine power, P m and electrical power, P e . As such, injecting an appropriate mechanical input power in accordance to the electrical power demand and losses at a critical time and condition will avoid major supply interruption due to unnecessary tripping of circuit breaker during transient instability. This paper presents Evolutionary Programming (EP) approach to optimize the mechanical input power in order to prevent transient instability in the system. The optimization is based on Area-based COI-referred Transient Stability Indexes: COI Angle and COI Speed, for a three area system with six generators. Results obtained from the experiment revealed that the EP approach is able to give an optimal solution.

A method for evolving artificial neural networks using Cartesian Genetic Programming (CGPANN) is proposed. The CGPANN technique encodes the neural network attributes namely weights, topology and functions and then evolves them. The performance of the algorithm is evaluated on the well known benchmark problem of double pole balancing, a nonlinear control problem. The phenotype of CGP is transformed into ANN and tested under various conditions in the task environment. Results demonstrate that CGPANN has the ability to generalize neural architecture and parameters in substantially fewer number of evaluations in comparison to earlier neuro-evolutionary techniques. We have also tested the CGPANN for generalization with different initial states (not encountered during evolution) over a range of evolved genotypes and obtained good results.
