At the nanoscale domain, the simulation, design, and optimization time of the circuits have increased significantly due to high-integration density, increasing technology constraints, and complex device models. This necessitates fast design space exploration techniques to meet the shorter time to market driven by consumer electronics. This paper presents non-polynomial metamodels (surrogate models) using neural networks to reduce the design optimization time of complex nano-CMOS circuit with no sacrifice on accuracy. The physical design aware neural networks are trained and used as metamodels to predict frequency, locking time, and power of a PLL circuit. Different architectures for neural networks are compared with traditional polynomial functions that have been generated for the same circuit characteristics. Thorough experimental results show that only 100 sample points are sufficient for neural networks to predict the output of circuits with 21 design parameters within 3% accuracy, which improves the accuracy by 56% over polynomial metamodels. The generated metamodels are used to perform optimization of the PLL using a bee colony algorithm. It is observed that the non-polynomial (using neural networks) metamodels achieve more accurate results than polynomial metamodels in shorter optimization time. © 2012 IEEE.

One of the chief challenges of wearable sensing is adapting electronic components and sensors to the wearable environment. Electronic components are often rigid, bulky, and impermeable: factors that usually detract from wearing comfort. Here, we present a novel stretch sensor fabricated using the top thread of a standard industrial coverstitch machine. The machine is common in apparel production and offers the ability to easily fabricate custom-placed stretch sensors on textile and apparel products. The sensing properties of the stitch are enabled by a conductive thread which increases its electric resistance as the fabric is stretched, due to the geometry of the stitches. Our empirical analysis shows a sensor response in the order of 10 ohms, with almost linear behavior prior to saturation (when the stitch is fully stretched) for low-frequency extensions of 119% of initial sample length. An equivalent electrical model is presented for theoretical modeling of the sensor behavior.

This paper presents a new concept for automated reconfiguration control that is based on past model-based system analysis, load modeling and integrated system recovery analysis research and development. The approach uses a software based supervisory level control application that: (1) Monitors device level distribution protection device operation, (2) Generates isolation refinement and restoration switch operation lists using a model-based reconfiguration algorithm, and (3) Uses the switch operation list to remotely operate switches, reclosers and circuit breakers through Supervisory Control and Data Acquisition (SCADA) to speed up fault recovery actions and reduce the size of outaged areas. The paper provides an overview of the model-based analysis concepts used to implement the reconfiguration controller and analysis algorithm, and also discusses reconfiguration algorithm design and operation.

A new index for passive islanding detection is proposed. The approach exploits the inherent harmonic distortion produced by grid-connected power converters as well as the frequency dependent changes in the grid impedance as seen by the distributed generator before and following islanding. The new index is computed from the variation of signal energy over a certain band of frequencies contained within a virtual power signal. The virtual power signal is obtained from measurements of voltage and current at the point of common coupling. The approach is validated via simulation and is demonstrated on a 7kW distributed generator system. © 2012 IEEE.

We propose a simplified analog design cycle to generate reconfigurable and accurate prototype of several analog ICs. On applying the design cycle a comprehensive design methodology is being developed that make designs customizable and adaptable by a field user. The basic design of a second generation current controlled current conveyor is first analyzed to estimate the basic circuit configuration to verify its basic functionality. Secondly using its small signal equivalent model, ac and dc characteristics are being derived in terms of threshold voltage of transistors, present in the circuit. Indeed, with the help of floating gate transistors, which has a feature of post fabrication programmability of its threshold voltage, an accurate and reconfigurable prototype of the design can be obtained. The circuit is simulated using BSIM3 level49 MOSFET models in T-Spice 0.35m CMOS process. Various Characteristics of CCCII are being derived and estimated their sensitivity with respect to threshold voltage of respective floating-gate transistors. The simulated results demonstrate that by programming threshold voltages, fine tuning of circuit specifications with wide spectrum can be achieved. The designs fabricated using our methodology can be adaptive to any desired value of specification with very high precision (about 13bit programming precision can attain with floating gate transistor). It can also make Analog ICs immune to most drawbacks like processes variations, device degradation by introducing new possibilities such as self correction and adaptability. © 2012 IEEE.

Determining Event Ordering in Mobile Ad Hoc Networks

Determining event ordering has always been a crucial issue in distributed computing. A well known model for describing event ordering is the happened-before relation. However, the traditional happened-before relation model is inadequate to faithfully characterize event ordering in recent emerging mobile ad hoc networks (MANETs), which usually have no fixed supporting infrastructure and may experience dynamic network topology changes. In this paper, we first propose a new relation, called the extended-happened-before relation, to model the ordering of events for a MANET. Then we present an algorithm to assign logical time to events such that the extended-happened-before relation between events can be decided by comparing their timestamps. We finally show how to construct consistent global snapshots in a MANET when the ordering of events can be determined.

Due to the limited power constraint in sensors, dynamic scheduling with data quality management is strongly preferred in long lifetime monitoring applications. But typical techniques treat data management as an isolated process on only selected individual nodes, e.g. the centroid node. In this paper, we propose and evaluate an aggressive data reduction algorithm based on error inference within sensor segments. The architecture integrates three parallel dynamic error control mechanisms to optimize the trade-off between energy saving and data validity. We demonstrate that not only substantial energy savings can be achieved but also that an error bound specified by the application can be guaranteed. Moreover, we have investigate the system performance by using the realistic historical soil temperature data as an experimental context. The experimental results demonstrate that the system error meets the specified error tolerance and produces up to a 50 percent of the energy savings compared to several sensing schemes. © 2012 IEEE.

IEEE International Conference on Fuzzy Systems (FUZZ-IEEE)

作者： Pintu Chandra Shill Md. Faijul Amin M. A. H. Akhand Kazuyuki Murase Department of System Design Engineering University of Fukui Fukui Japan Department of Computer Science and Engineering KUET Khulna Bangladesh

A Type-2 Fuzzy logic controller adapted with quantum genetic algorithm, referred to as type-2 quantum fuzzy logic controller (T2QFLC), is presented in this article for robot manipulators with unstructured dynamical uncertainties. Quantum genetic algorithm is employed to tune type-2 fuzzy sets and rule sets simultaneously for effective design of interval type-2 FLCs. Traditional fuzzy logic controllers (FLCs), often termed as type-1 FLCs using type-1 fuzzy sets, have difficulty in modeling and minimizing the effect of uncertainties present in many real time applications. Therefore, manually designed type-2 FLCs have been utilized in many control process due to their ability to model uncertainty and it relies on heuristic knowledge of experienced operators. The type-2 FLC can be considered as a collection of different embedded type-1 FLCs. However, manually designing the rule set and interval type-2 fuzzy set for an interval type-2 FLC to give a good response is a difficult task. The purpose of our study is to make the design process automatic. The type-2 FLCs exhibit better performance for compensating the large amount of uncertainties with severe nonlinearities. Furthermore, the adaptive type-2 FLC is validated through a set of numerical experiments and compared with QGA evolved type-1 FLCs, traditional and neural type-1 FLCs.
