Implementation of a predictive controller for a sensorless interior permanent-magnet synchronous motor drive system

This study proposes a predictive controller design for a sensorless interior permanent-magnet synchronous motor drive system. The controllers include a current-loop predictive controller and a speed loop predictive controller with an external load estimator. In addition, a rotor position estimator with on-line tuning stator resistance and q -axis inductance has been designed to reduce the estimating error. By using the proposed control algorithms, the closed-loop sensorless interior permanent-magnet synchronous motor drive system can achieve fast transient response, satisfactory load disturbance response and good tracking response. A digital signal processor, TMS320F2812, is used to perform the rotor position estimating algorithm and the predictive control algorithm. As a result, the hardware is very simple. The experimental results can validate the theoretical analysis and show that the predictive controllers have better performance than the proportional integral (PI) controllers.
Testing automation tools for secure software development

Abstract : Software testing is a crucial step in the development of any software system, large or small. Testing can reveal the presence of logic errors and other flaws in the code that could cripple the system's effectiveness. Many flaws common in software today can also be exploited to breach the security of the system on which the software is running. These flaws can be subtle and difficult to find. Frequently it takes a combination of multiple events to bring them out. Traditional testing techniques focus on dealing with errors as they arise during normal operation of the system. This technique is not particularly effective. Thus, recent research has focused on developing new, more effective software testing techniques. Two such techniques are combinatorial testing and fuzz testing. This thesis explores the effectiveness of combining both combinatorial testing and fuzz testing into a single software testing tool to aid in the discovery of subtle system flaws. The tools developed for testing automation by this thesis will aid in the development of secure software, and bolster the ranks of testing techniques available to future developers.
IMPROVING THE PERFORMANCE OF A VIBRATION ENERGY HARVESTING DEVICE USING MAGNETS

Harvesting energy from ambient vibration source is a promising method for providing a continuous source of power especially for low power microelectromechanical system (MEMS). Thus, multiple methods were proposed in order to overcome the linear resonant generator system. This paper presents experimental results on two modes (softening and bi-stable) the use of magnets for improving the functionality of energy harvesting device under constant input displacement. The results for four configurations which operate in attractive and repulsive mode with a fixed gap between the magnets are investigated. The result shows that there is a wider bandwidth for the device operating in the softening mode.
Monitoring Gear Fault by Using Motor Current Signature Analysis and Fast Kurtogram Method

Conventional methods (i.e. time and frequency analysis) can routinely be used to reveal gear fault-indicating information in the current signal. In recent years, Wavelet analysis, which can lead to a clear identification of the nature of faults, are widely used to describe rotating machine condition. The Capability of this method in the detection of any abnormality can be further improved when its low-order frequency moments are considered. This paper presents the use of the Fast Kurtogram in the early detection and condition monitoring of crack fault. For this purpose, a dynamic model of an electromechanical system which is a simple stage gearbox (with and without gear defect) driven by a three phase induction machine is developed. Then motor stator current is analyzed by using a Fast Kurtogram method. This method is suitable for such diagnosis and gives valuable information about the presence and effects of the crack tooth defect
ACCIDENT DATA ANALYSIS IN SUPPORT OF COLLISION AVOIDANCE TECHNOLOGIES

This report summarizes the results of an effort to develop and rank collision scenarios. Review of existing literature showed that there has been relatively little work in this area. In exploring and building collision scenarios, police reported accident files from Michigan and Washington were used, along with data from the National Accident Sampling System, and the Crash Avoidance Research Data file. The project focused on common accidents of ordinary drivers. Ultimately. the project was restricted to passenger car accidents which did not involve pedestrians or pedacyclists, and drivers who had not been drinking or indicated to have been driving recklessly. An 18-level collision configuration variable was constructed which included the number of vehicles involved, their relative orientation, intent to turn, relation to intersection, and traffic control at the intersection. Distributions of this variable were determined for driver age, area type (urban or rural), road type, and light condition. The distributions were quite stable across the four data sets.
CRM at the Speed of Light: Capturing and Keeping Customers in Internet Real Time

From the Book: Everyone knows that customers are the critical component of a successful business, if for no other reason than people tell you all the time. Countless books have been written about how to make customers happy and acquire new ones. Companies do satisfaction surveys, attend seemingly endless seminars, virtually anything to give them a leg up on the competition and make their customer base an impenetrable force, rather than a weakness to be exploited. As far back as 1987, when ACT! 1.0 shipped, managing relationships with software started to change lives-and not just the relationship being managed, either. Business professionals began to understand that their weaknesses in everything from memory to accountability could be compensated for, resulting in a professionalism that helped them stand out and close more business. ACT! spawned other products for companies of all sizes, and an industry was born: sales force automation (SFA). Since then, customer service, marketing, and e-business have evolved into eCRM and extended those seemingly simple ideas of sharing customer history and information, and turning it into knowledge that enables an entire organization to act as a unit. This glue that interconnects the experiences of numerous individuals and groups with your customer is becoming more complex and business-critical every day. Every vendor is trying to make their mark, and the waters are becoming increasingly murky. Just trying to navigate the numerous new acronyms-PRM, MRM, ERM, BRM-has made a once very clear idea more like dyslexic soup. That's why Paul Greenberg's book is such a breath of fresh air. Actually, it's more like a wind that blows away the cloudsof hype and marketing mumbo jumbo. Finally, there is a consolidated source on this subject that can be used by the novice as well as the expert. It's like eCRM university between two covers. From the history of what created this market to how to implement the right solution for your size business, it's all here. Although most companies use some type of automation for their sales forces, marketing organizations, and customer service groups, at last count only 4 percent of U.S. companies have integrated them and other Web resources like online product configuration and e-commerce. This industry has yet to reach its adolescence in the United States and in many parts of the world is just getting out of diapers. When there is an enormous amount of change anticipated for an industry, it's best to know as much as you can about its history, so you can get tied in to its present armed with equivalent knowledge of those more experienced. Paul has a unique ability to not only bring these historical insights, but also to broaden our perceptions of what relationships are. By presenting these insights and pulling together many perceptions of possible paths the industry can take, we may be armed with a better understanding, and thus more adept at taking advantage of the future.

Sustaining the future through virtual worlds

Virtual worlds (VWs) continue to be used extensively in Australia and New Zealand higher education institutions although the tendency towards making unrealistic claims of efficacy and popularity appears to be over. Some educators at higher education institutions continue to use VWs in the same way as they have done in the past; others are exploring a range of different VWs or using them in new ways; whilst some are opting out altogether. This paper presents an overview of how 46 educators from some 26 institutions see VWs as an opportunity to sustain higher education. The positives and negatives of using VWs are discussed.

Static optical sorting in a laser interference field

We present a unique technique for optical sorting of heterogeneous suspensions of microparticles, which does not require the flow of the immersion medium. The method employs the size-dependent response of suspended dielectric particles to the optical field of three intersecting beams that form a fringelike interference pattern. We experimentally demonstrate sorting of a polydisperse suspension of polystyrene beads of diameters 1, 2, and 5.2 m and living yeast cells. © 2008 American Institute of Physics.

Recent Advances in Continuous-Flow Particle Manipulations Using Magnetic Fluids

Magnetic field-induced particle manipulation is simple and economic as compared to other techniques (e.g., electric, acoustic, and optical) for lab-on-a-chip applications. However, traditional magnetic controls require the particles to be manipulated being magnetizable, which renders it necessary to magnetically label particles that are almost exclusively diamagnetic in nature. In the past decade, magnetic fluids including paramagnetic solutions and ferrofluids have been increasingly used in microfluidic devices to implement label-free manipulations of various types of particles (both synthetic and biological). We review herein the recent advances in this field with focus upon the continuous-flow particle manipulations. Specifically, we review the reported studies on the negative magnetophoresis-induced deflection, focusing, enrichment, separation, and medium exchange of diamagnetic particles in the continuous flow of magnetic fluids through microchannels.
Development of a visual-teach-and-repeat based navigation technique on quadrotor aerial vehicle

The objective of this thesis is to develop a vision-based navigation and control technique for quadrotor to operate in GPS-denied environments. The navigating technique has been developed while using Visual-Teach-and-Repeat (VT&R) method. This method is qualitative where the position of the quadrotor is estimated based on a set of reference images. These reference images are collected while taking the quadrotor manually along a desired route. Each image, collected in the database, represents one segment of the desired route. The features are extracted from these images using a well-known method, Speeded-Up Robust Features (SURF) [1]. When the quadrotor is navigated along the desired route (repeat mode), the quadrotor performs self-localization. Three methods of self-localization are presented. In method I, the SURF features observed on the current image are matched with the SURF features of the reference images to compute the probability value of each segment in the desired route. The segment that provides the best probability value is chosen as the current segment of the quadrotor. To improve the accuracy of localization, in the method II, the condition of feature-size relation with spatial distance is imposed. In the method III, the estimation of the current segment of the quadrotor is built on Bayes’s rule. Based on the appearance-based error of feature coordinates, the system computes qualitative motion control commands (desired yaw and height) for the next movement in order to control the quadrotor to follow the desired route. This computation is developed on Funnel Lane theory, which was originally proposed in [2], in order to 2D navigate ground vehicle following the desired route. The thesis extends it to 3D navigation for the quadrotor. Funnel Lane theory qualitatively defines possible positions where the vehicle can fly straight by the constraints of features coordinates between the current image and the reference image. If the quadrotor locates outside the funnel lane, it will be navigated back to the funnel lane. A nonlinear geometric controller has been developed to convert the motion control commands, generated basing on VT&R technique, into control inputs necessary for the four rotors in the quadrotor. The design of proposed controller is simplified by concentrating on the errors of rotational matrix, instead of attempting to access the errors of each degree of freedom. The quadrotor for this thesis is chosen as the well-known AR.Drone model [3]. The whole system is modeled and simulated in Gazebo simulator using Robot Operating System (ROS). Four image databases have been used for testing self-localization: two databases around Engineering building of Memorial University of Newfoundland, COLD database and New College database. With proposed VT&R technique, the quadrotor is able to independently follow a long route without GPS-information or the support from an external tracking system. The proposed system has a simple implementation, inexpensive computation and high potential for exploring and searching-and-rescuing missions.

Molecular characterization and subtyping of Blastocystis in urticarial patients in Turkey

Objective: To investigate Blastocystis’ etiologic role and association with gastrointestinal symptomatology in acute and chronic urticaria patients and to identify Blastocystis subtypes responsible for urticaria. Methods: The study included urticaria patients and healthy individuals that presented to our polyclinic between June 2015 and May 2017. The participants were assigned into Group I (137 patients), subdivided into acute (72) and chronic urticaria patients (65), and Group Π (129 control individuals). Blastocystis presence was investigated by native-Lugol examination, trichrome staining, PCR using sequence tagged site primers, and DNA sequencing analysis. The phylogenetic tree was constructed. Results: The native-Lugol and trichrome staining methods revealed that 16 patients (16/133, 12.0%) had Blastocystis-positive stool samples, of which seven samples (7/133, 5.3%) belonged acute and nine (9/133, 6.8%) to chronic urticaria patients. Concerning Blastocystis subtypes, of the acute urticaria patients, three had subtype 1 (ST1), one had ST2, and three had ST3. Of the chronic urticaria patients, one had ST1 and eight had ST3. Blastocystis positivity was detected in two control individuals (2/123, 1.6%), both being ST3. All subtypes identified by PCR were confirmed by the sequencing analysis. The acute and chronic urticaria groups showed no statistically significant differences for Blastocystis positivity (P=0.60) and subtype distribution (P=0.15). A statistically significant difference was found between the urticaria patients and the controls for Blastocystis positivity (P<0.01), but not for subtype distribution (P=0.67) or for Blastocystis presence and gastrointestinal complaints. Conclusions: This study on Blastocystis subtype distribution among Turkish urticaria patients showed results consistent with the literature. It was concluded that Blastocystis should be kept in mind in patients with urticaria.
A Systematic Study Of Software Quality – The Objective Of Many Organizations

The quality is one of the main objectives of many software organizations which help one to deliver software products that meet and or exceed customer expectations. In Software engineering Software quality and software metrics are one of the most active research areas. Software quality model is one of the vital place where we can obtained the data to improve the performance of various projects. This improvement can be measured in terms of quality, customer satisfaction, less cost and time of quality. Software metrics and the software quality models play an important role in measurement of software quality. Many researchers have proposed many different models for quality to measure software quality of any product. In this paper we are going to check all companies’ quality policies and also check what kind of process improvement models they used to ensure the quality level.

Partial Tracking Based on Future Trajectories Exploration

This paper introduces a partial-tracking algorithm suitable for the sinusoidal modelling of polyphonic sounds. A new method, based on the backward exploration of possible extensions of the partials in future frames, is proposed to cope with the lack or corruption of spectral data. The allocation of spectral peaks to a partial is done by considering possible trajectories in future frames where frame hoping is allowed. A suitable transition probability that takes into account missing or rejected peaks is proposed. The trajectory that exhibits the highest probability is searched for and the corresponding peak for the current frame is chosen to extend the partial.
Reproducing Applause-Type Signals with Directional Audio Coding

Applause-type signals are known to be challenging for parametric multichannel coding and spatial audio reproduction techniques. This phenomenon is investigated in the context of directional audio coding (DirAC), and it is found that the artifacts originate from the decorrelator processing of the transients of individual handclaps at the decoder. Commonly the decorrelation causes temporal smearing of the transients, producing prominent artifacts. It is shown that very good audio quality can be obtained with applause signals if the temporal resolution in encoding is high enough to analyze each distinct handclap in the signal separately. An implementation of DirAC for the reproduction of surround sound is shown, which is fine-tuned with special focus on applause signals. In addition the results from formal listening tests showing the subjective quality obtained with two well-known applause recordings are presented.
CDK4/6 inhibition in cancer: the cell cycle splicing connection

ABSTRACT Cyclin-dependent kinase −4 and −6 (CDK4/6) inhibitors are currently being assessed in clinical trials for the treatment of many cancers including melanoma. While investigating the mechanisms of CDK4/6 inhibitor resistance in melanoma, we uncovered a mechanism of action of these inhibitors in regulating the expression of both the mouse double minute 4 (MDM4) oncogene and tumor protein p53 (TP53).

The specific area of hypothesis of the paper is to use of the electrical energy produced by a piezoelectric material as a source for lighting street lights on highways.
Analysis of Tumble and Swirl Motions in a Four-Valve SI Engine

Tumble and swirl motions in the cylinder of a four-valve SI engine with production type cylinder head were investigated using a cross-correlation digital Particle Image Velocimetry (PIV). Tumble motion was measured on the vertical symmetric plane of the combustion chamber. Swirl motion was measured on a plane parallel to the piston crown with one of intake ports blocked. Large-scale flow behaviours and their cyclic variations were analysed from the measured two-dimensional velocity data. Results show that swirl motion is generated at the end of the intake stroke and persists to the end of the compression stroke. Tumble vortex is produced in the early stage of the compression stroke and distorted in the late stage of the stroke. The cyclic variation of swirl motion is noticeable. The cyclic variation in tumble dominated flow field is much greater. Distribution of two-dimensional fluctuation kinetic energy field for swirl motion gradually becomes homogeneous in the late stage of the compression process, while for tumble motion the distribution of velocity fluctuation field is inhomogeneous during the whole compression stroke.
