    ABSTRACT: A low bit-rate ZigBee-based sensor network carrying scalable video streams will be considered. A cross-layer priority algorithm that combines the state of the channel and the quality of the video traffic will be suggested to optimize the required quality of service of the video streams. The proposed algorithm prioritizes the transport of the basic frames, and thus minimizes the carried enhancement orphan frames. It also avoids transmitting the enhancement frames related to a dropped basic frame. A noticeable improvement in the end-to-end delay of the video stream was achieved, an increase in the carried base frames, and a decrease in the orphan frames provided both an enhanced quality of the received video stream and an improvement in the channel utilization.

    ABSTRACT: In this paper, static synchronous compensator (STATCOM)-based damping stabilizers are designed and implemented to enhance the damping of the low frequency oscillations. The effectiveness of STATCOM gain and phase modulation channels to improve the damping characteristics is investigated. The coordination among the internal ac and dc voltage controllers and the proposed damping controllers on each channel is designed. Differential evolution as an intelligent optimization technique is considered to design the STATCOM supplementary damping controllers. The STATCOM-based stabilizer is implemented on a real-time digital simulator (RTDS). The RTDS experimental setup of STATCOM with a power system is verified. The nonlinear time domain simulation of the considered power system is presented to validate the proposed damping stabilizers of low frequency oscillations. Comparisons with the reported results in the literature demonstrate the effectiveness of the proposed stabilizer.

    ABSTRACT: In this paper, a new method for impulsive noise reduction and edge preservation in images is presented. Images of different characteristics corrupted with a wide range of impulsive noise densities using two impulsive noise models are examined using the proposed method. In the detection stage of the method, two conditions have to be met to determine whether an image pixel is noisy or not. Two predetermined threshold values are involved in the computation of the second condition to differentiate between corrupted and uncorrupted pixels. Only pixels determined to be noisy in the detection stage are filtered in the next filtering stage where small size sliding windows are used to significantly reduce blurring effects in the output restored images. Several measuring indices have been used to examine the performance of the proposed method compared with many existing state-of-the-art methods in the literature of the image restoration field. Extensive simulation results show the superior performance of the proposed method over other techniques in terms of restoration quality, and preservation of images with fine details and edges.

    ABSTRACT: A new method to model the end effect for single-sided short-primary linear induction motors (LIMs) is developed by considering the effect of nonzero leakage inductance of the secondary. The well-established equivalent circuit model—introduced by Duncan in the 1980s—is improved by taking nonzero leakage inductance into account. This new approach closes the gap between predictions and test results of a transit LIM. It also allows for reliable model utilization in engineering practice. The analytical predictions are verified with the field test data collected from a full-scale LIM designed for public transit systems.

    ABSTRACT: This paper obtained the switching impulse flashover characteristic of live working complex gap on extra high voltage (EHV) and ultra high voltage (UHV) high-voltage transmission lines by a large number of experiments. Based on the experimental data and the leader inception discharge model, the complex gap discharge development during the process of entering equipotential and its influencing factors have been analyzed with the electric filed calculation method. Moreover, considering the practical conditions in live working sites, a complex gap discharge model appropriate for side live working on EHV and UHV high-voltage transmission lines has been proposed by introducing a revision coefficient $k_{m}$ . It has been found that $k_{m}$ is related to the working position and the structure of high-voltage electrode. Through further research on the establishment of the functional relationship, it can provide a comparable accurate theoretical calculation method for the research on the complex gap of live working and can give a guideline for optimizing the test plans.

    ABSTRACT: This paper develops an algorithm to estimate the space shift, time shift (or time delay), and parameters in a shifted continuous 2-D system described by a 2-D partial differential equation. Using the linear filter method, the simultaneous estimation of shifts and parameters is achieved. Also, the instrumental variable technique is used to remove the least square estimation bias, which is due to measurement noise. There are some methods to estimate the time shift in 1-D systems. However, no method has been proposed so far to estimate the shifts in 2-D systems. To show the performance of the proposed algorithm, one illustrative numerical example is discussed.

    ABSTRACT: The ubiquitous nature of Bluetooth equipped devices has made it opportunistic to scavenge information that can be repurposed for applications other than initially intended. One such opportunity is in vehicular traffic monitoring, whereby sampling of Bluetooth radios serve as proxies for vehicles and consequently for traffic density and flow. This paper discusses a complete data collection system developed at the University of Manitoba that utilizes a variety of wireless networking technologies and devices to collect inferred traffic data at an intersection along a major thoroughfare in an urban setting. Specifically, a wireless sensor network of slave probes was designed and implemented with the objective to collect Bluetooth device information for this purpose. To facilitate easy setup and a long battery life, a solar-powered probe design was investigated. Data from each slave probe is communicated to a master node through XBee communication, where it is stored on a secure digital (SD) memory card before being transmitted to a central server every five minutes over a global system for mobile communications (GSM) cellular network. The server parses the data received and stores it in a database. Consumer and corporate websites may then access this database to display archived data or current data in real-time to various users.

    ABSTRACT: The objective of the software product line engineering paradigm is to enhance the largescale reuse of common core assets within a target domain. Reuse is facilitated by systematically organizing and modeling the core assets and the relationships between them. One of the main core assets of a domain is the model for representing the available functional aspects, often known as features, within structured forms such as feature models. The selection and composition of the most suitable or desirable set of features for a given purpose allows the rapid development of new final products from the software product line. Product developers are, in most cases, not only interested in building applications that possess certain functional characteristics but are also concerned with nonfunctional properties of the final product, such as reliability. To this end, we propose a componentbased software product line reliability estimation model that is able to provide lower and upper reliability bounds guarantees for a software product line feature model, its specializations and configurations. Our model builds on top of the reliability of the individual features that are present in the product line and provides best- and worst-case estimates. Our work is based on an essential and widely used assumption that features are implemented using self-contained software components or services whose reliability can be determined independently. We also propose reliability-aware configuration methods that ensure the satisfaction of both functional and reliability requirements during the application development process. We offer our observations and insight into the performance of our reliability estimation model and provide analysis of its advantages and shortcomings.

    ABSTRACT: The copy-on-write update policy is a powerful technique for data protection. Unfortunately, it introduces a recursive update problem, which causes several side effects to a storage system, such as WRITE amplification and performance degradation. This paper elaborates on how these effects are introduced by recursive update and how serious they are. In order to evaluate these effects, an extended BTRFS (the Linux B-tree Filesystem) prototype was developed to implement the update-in-place update policy for comparison. This paper reports that recursive update can lead to (29.5times ) WRITE amplification and 71% performance degradation in a single WRITE operation, as well as (18.3times ) WRITE amplification and 33% performance degradation in an e-mail server workload. These results indicate that taking recursive update into consideration is important in developing high performance and reliable file and storage systems.

    ABSTRACT: Hardware transactional memory (HTM) offers a promising parallel programming model for chip multiprocessors. The performance aspect of HTMs has been explored extensively, whereas little research has addressed the power of HTMs. In this paper, we investigate power consumption in HTMs and propose two optimization techniques. The first optimization technique is adaptive snoop granularity (ASG). HTMs rely on cache coherence protocols to detect conflicts and maintain consistency of transactional data. One of the main design issues facing HTMs is the growing number of snoops required to maintain coherency of transactional data. We found that many transactions access consecutive memory locations which are not shared by other transactions. ASG monitors these transactional accesses and dynamically changes snoop granularity to reduce the power of the interconnection network and eliminate needless cache snoops. The second optimization technique is transactional snoop filtering (TSF). TSF dynamically tracks accesses to the coherence caches and eliminates cache snoops that would result in cache misses. TSF relies on small filters to monitor cache addresses. Energy is reduced as accesses to the much more demanding data caches are decreased. We extended the Gem5 simulator to model ASG and TSF. Our simulation results show that ASG and TSF are effective and reduce energy of interconnects and caches up to 44% and 89%, respectively.

    ABSTRACT: Power efficiency and utilization are important factors for a cloud service provider. In this paper, we provide one quick design method both for a high-current density power distribution printed circuit board (PCB) design and for an improvement of a high end server system. This design method also takes into consideration both load balance and failures of a multipower supply server system, when the server system is supported by a redundancy power source. Our design is based on a system power source to sink the current path for both PCB copper shape dimension and thickness design, and to add some power or ground via for stitching either each power or ground plane on a multilayer PCB design to reduce direct current resistance. It also considers the airflow necessary for cooling the power distribution board to lower the temperature rise when high current is delivered with a resulting lower power loss and higher power efficiency and performance per watt.

    ABSTRACT: A novel algorithm for subtracting the artifacts from an electrocardiogram (ECG) signal and detecting the QRS complex based on empirical mode decomposition has been designed, tested, and evaluated. This method can remove both the noise of the power line interference and baseline wander from the ECG signal with minimum distortion, and R peaks can be exactly detected. The method is tested and evaluated using the records from the MIT-BIH arrhythmia database and the ECG signal data acquired from a wearable low-power ECG monitoring device. In the experiments, the correlation coefficient between the clean signal and denoised signal can be up to 0.997, and it is greater than 0.970 even in severely contaminated situations. The detection algorithm for the wearable monitoring device shows that the QRS detection rate is over 99.8% and that the sensitivity is over 99.9%. When compared with other detection methods, this proposed algorithm holds the best performance in severely noise-contaminated situations. The experiment's results demonstrate that the algorithm can effectively delineate the ECG signal under different sampling rates as expected.

    ABSTRACT: In this paper, a novel high-throughput very large scale integrated circuit architecture for a real-time implementation of intensity modulation direct detection optical orthogonal frequency division multiplexing system is proposed, achieving the highest throughput reported to date. The proposed architecture utilizes a fast, pipelined, and parallel inverse fast Fourier transform/fast Fourier transform in the transmitter/receiver, which is customized to satisfy the throughput requirements of the advanced optical systems. In addition, an efficient high-accuracy equalization method is developed, improving the system performance compared with the conventional linear equalizers. To evaluate the system performance, the OptiSystem software is used to model the optical channel and a Virtex-6 ML-605 evaluation board is used as the implementation platform. Moreover, the synthesis results in a 180-nm CMOS technology prove that the proposed architecture achieves a sustained throughput of 22.5 Gb/s with a 4.89- ({{rm mm}^{2}}) core area.

    ABSTRACT: In magnetic resonance imaging, it is a common to acquire multiple scans of the K-space so that the effects of noise and motion artifacts can be reduced by averaging the K-space scans. However, sampling the full K-space is time consuming; to reduce the scan time, compressed sensing (CS)-based reconstruction algorithms are employed to recover images from partially sampled K-space scans. A recent study showed that the recovery can also be achieved by exploiting the rank deficiency of the underlying images. In this paper, we will show how the reconstruction can be further improved by combining CS techniques with low-rank recovery methods. Our proposed formulation leads to a least-square minimization problem that is regularized by an ℓ1-norm and a nuclear norm. There is no efficient and accurate algorithm to solve this problem; therefore, we derive an algorithm to solve the said problem based on the Split Bregman approach. The results show that our proposed technique reduces the reconstruction error by about 40%.
