Increasing penetration of wind power into the generation mix has necessitated the integration of wind farms in the daily planning and dispatching operations of independent system operators. This paper models a simple and intuitive cost function that can dispatch power among multiple wind farms in an economically equitable manner. The cost function is used in an optimal power flow problem for the IEEE 14 bus system with three wind farms. The results indicate that the proposed cost function can prevent the underutilization of certain wind farms due to their location while satisfying the system operating constraints.

Advances in protein three-dimensional structure prediction depend strongly on the ability to measure the quality of a protein model. One of the best single measures of the model quality is the area under the graph of the so-called “GDT function” that assigns to each distance cutoff θ the percentage of residues in the model structure that can be superimposed at distance ≤ θ from the corresponding residues in the experimental structure. In lieu of a method capable of computing this measure, researchers often resort to its approximation GDTTS. In this short paper we present the first theoretical framework for the development of an algorithm capable of computing near-optimal estimates of the area under the GDT curve of a protein model in polynomial time.

The desire for advancement of human space exploration brings the need for an adaptive, next generation health monitoring system in the form of a Wireless Body Area Network (WBAN). The application of wireless networks has yet to be utilized in the space industry allowing for the untapped potential for next generation devices that increase mission awareness and safety. WBAN was designed to meet the requirements of space exploration, allowing for ease of movement and flexibility through non-restrictive components and a wireless network. The proposed system consists of two subsystems: a sensor network made up of a microcontroller, a Bluetooth transceiver, and an external antenna; and an Android device used as the data monitoring system. The Bluetooth transceiver transmits data from the sensors, via the external flexible antenna to the Android tablet. The data is collected and displayed via a custom-built application on the tablet. The application also keeps and monitors the total power of the system allowing for continuous vital sign monitoring.

A novel five level three-phase inverter topology, based on the development of a computing model to pre-calculate the switching angles, is being proposed. The main advantage of this topology is the overall reduction in the number of power electronic switches, reduction in pre-calculated switching angles and reduction in the total harmonics distortion in the output voltage. Applications of this topology include dynamic hybrid battery/inverter and Photovoltaic/inverter systems to improve overall system operation and performance and at the same time improve output voltage and power generation quality. The proposed topology has been modeled and validated using Matlab software.

Given a graph, there are many different reasons for finding communities in a graph. Numerous algorithms have been proposed for finding communities on graphs. Many of those algorithms are time consuming. The Jaccard metric, introduced in the context of the geographic location of botanical species, has been used to find communities. An algorithm to find communities based on the Jaccard metric was parallelized using OpenMP. Performance results are reported.

With the improvements in sensor technologies and image processing algorithms, computer vision has become a major tool for robots to recognize and gauge their surroundings. For instance, the Kinect sensor can be used as an excellent depth camera for indoor navigation. However, there exist situations that need recognition and spatial interpretation of the environment using limited hardware resources. The Kinect is not suitable for outdoor use while LIDAR is too large and expensive to be installed on an autonomous miniature surveillance drone. Therefore, the use of a single camera is the only feasible option for many embedded applications. Hence, this paper examines different Structure from Motion (SfM) implementations, and focus on methods that require only one camera to perform an efficient 3D mapping of a scene.

Electroencephalography (EEG) is a promising technique to record brain activities in natural settings. However, EEG signals are usually contaminated by Ocular Artifacts (OA) such as eye blink activities. Removal of OA is critical to obtain clean EEG signals required for the feature extraction and classification. With the increasing interest in wearable technologies, single channel EEG systems are becoming more prevalent. Such ambulatory devices require real-time signal processing for immediate feedback. This paper presents a hybrid algorithm to detect and remove OA from single channel EEG signal using NeuroMonitor hardware platform. The algorithm first detects the eye blinks (OA zone) using Algebraic approach, and then removes artifact from OA zone using Discrete Wavelet Transform (DWT) decomposition method. De-noising technique is applied only to the OA zone to keep the critical neural information intact. The OA removal algorithm is applied to the online data for 0.5 sec epoch length. The performance evaluation is carried out qualitatively and quantitatively using time-frequency analysis, mean square coherence and other statistical parameters, i.e. Correlation Coefficient and Mutual Information. Processing time for DWT was significantly lower (x25) to that of SWT. This proposed hybrid OA removal algorithm demonstrates real-time execution with sufficient accuracy.

This paper reports on the development of a novel printed and flexible dry electrode sensor consisting of multi-walled carbon nanotube (MWCNT)/ polydimethylsiloxane (PDMS) composite for electrocardiogram (ECG) measurements. The sensor was screen printed using silver (Ag) flake ink on flexible polyethylene terephthalate (PET) substrate. MWCNT/PDMS was then bar coated on the screen printed electrode. The capability of the printed sensor, which is conformal enough to have a better electrode-skin contact without the use of wet gel and skin preparation, was demonstrated. The response of the flexible dry electrode sensor is analyzed and presented in this paper.

This paper presents a hybrid control system for the speed control of a three-phase squirrel cage induction motor (SCIM). The proposed method incorporates fuzzy logic with conventional controllers and utilizes the vector control technique. This method combines the advantages of fuzzy logic controller and conventional controllers to improve the speed response of the three-phase induction motor. Implementation and simulation results using MATLAB/SIMULINK of various hybrid system controllers such as (PI-, PD-, and PID-fuzzy) are compared along with PI controller in terms of several performance measurements such as rise time (tr), maximum percent overshoot (PO), and settling time (ts) at various load conditions. The results verified the effectiveness of the proposed hybrid speed controller under different operating conditions and demonstrated improved performance in speed tracking and system's stability.
