Harmonic Distortion Analysis of Multilevel Inverter Driven Induction Motor using Different Modulation Schemes

Induction motors experience losses due to hysteresis and due to eddy currents set up in the iron core of the motor. These are proportional to the frequency of the current. Since the harmonics are at higher frequencies, they produce higher core losses which results in increased heating of the motor core, which can shorten the life of the motor. Induction motors driven by advanced modulation schemes can be more efficient and can last for a longer duration of time. In this paper Induction motor driven by three level inverter using two modulation schemes, SPWM(Sine Pulse Width Modulation) and SVPWM (Space Vector Pulse Width Modulation) is used. The stator current of the motor is then analyzed using FFT (Fast Fourier Transform) and Wavelet transform for detecting the THD (Total Harmonic Distortion). Keywords—Multilevel Inverter, Sine Pulse Width Modulation (SPWM, Space Vector Pulse Width Modulation(SVPWM), Wavelet Transform.

Relationship with Lung Carcinoma in the Patients with Anthracosis by Detection of Expression of P16 and MUC1 Genes

Introduction and objective: Anthracosis is a pneumoconiosis caused by coal dust. The term “pneumoconiosis” refers to an occupational lung disease caused by long-term inhalation of dust. To achieve more efficient diagnosis and treatment methods, changes in the expression of MUC1 and P16 genes in the patients with anthracosis and their relationship with none small cells lung carcinoma were examined. Methodology: Thirty anthracosis samples (center of the lesion) and thirty healthy samples (edges of the lesion) were collected from anthracosis patients diagnosed by a specialist. The patients signed a written letter of consent beforehand. The expression of MUC1 and P19 biomarkers was measured through Real-Time PCR. The relationship of the expression of biomarkers with tumor staging and lung carcinoma stage was examined. Results: The two groups in the study were compared using t-test. P16 marker was positive at the center and edges of lesions in seven (out of 30) and 18 (out of 30) cases respectively. There was a significant difference between positive P16 markers at the center and edges of the lesions (p-value<0.001). MUC1 marker was positive at the center of lesions in 21 cases out of 30 (sensitivity = 70%) and it was positive at the edges of lesions in seven cases out of 30. In terms lesions (p-value<0.001). Conclusion: The results indicated a relationship between anthracosis and lung carcinoma. Clearly, the positive cases of P16 genes at the edges of lesions were higher than that at the center; while the positive cases of MCU1 gene at the center of lesions were higher than that at the edges. Further studies with larger sample groups are needed to provide more evidence. Keywords: Anthracosis disease- lung carcinoma- MUI1 Biomarker- P16 Biomarker
Scalable Optimal Test Patterns for Crosstalk-induced Faults on Deep Submicron Global Interconnects

Capacitance-coupling and mutual inductance between the neighboring wires of global interconnects give rise to crosstalk effects, which are one of the biggest signal integrity problems in DSM circuits today. Previous models for crosstalkinduced faults assume that all the wires of a bus act together to induce crosstalk effects on a single wire. Based on recent simulation results of Sirisaengtaksin and Gupta, we use a more general model of crosstalk-induced faults that allows tradeoffs between efficiency of tests and quality of tests. We construct provably optimal test patterns that covers all crosstalk-induced faults under this general model. Our test patterns admit simple generators for at-speed testing in BIST. The test methodology proposed here can result in huge savings in test cost. In particular, the required linear number of test patterns can be reduced to a constant number of test patterns by accepting only a few percent of error, thus allowing our test methodology to scale with bus width and technology.
Commentary: A Huge Ependymoma of the Cervical Spinal Cord with Subtle Atypical Manifestations and Hyperhidrosis

Submit Manuscript | http://medcraveonline.com The most public initial symptom in patients with cervical spine tumors is neck pain. The pain might start progressively and develop more prominent over a prolonged period of time. Patients may also have shoulder, arm, or leg pain as the tumor mass extends beyond the confines of the bone or spinal canal to involve the spinal cord or nerve roots. As the tumor remains to grow, numbness, tingling, in the arms or legs might be observed. Through additional growth, weakness in the arms or legs can progress, as well as a reduced capability to normal walk. There can even be with bladder and bowel function problems.
Cluster-based artificial contrasts for inhomogeneously distributed data with an indicator variable

Multivariate statistical process control is used for simultaneously monitoring several process variables. The original artificial contrasts (AC) are very useful for monitoring inhomogeneously distributed data with an indicator variable. The cluster-based AC improve it by considering separated clusters, respectively. Then the artificial data used for the AC overlap each cluster. Numerical experiments show that our method outperforms existing methods in terms of Type-II error rate.
Comparison of different methods for computing scaling parameter in the presence of trends.

In a large number of analysis of biological signals, such as ElectroEncephaloGrams or Heart Rate Variability, phenomena such as long range correlation or long term memory or self similarity or more generally scaling phenomena have been observed and are often used as a basis for diagnosis and the assertion of major physiological facts. It is therefore an important issue to be able to perform a relevant analysis (detection, estimation) of such phenomena on empirical data. For a reliable use of long-range correlation analysis, it is essential to be able to distinguish between trends (whatever their origin - external, apparatus - or internal but related to other biological mechanism such as breathing.) and long-range fluctuations intrinsic to the data. In this paper we compare estimates of the Hurst parameter based on i) Detrending Fluctuation Analysis, ii) wavelet analysis, iii) discrete variations. We discuss their capabilities for a reliable estimation of the scaling exponent, depending on the signal length and for different trends, using simulated and real data.
An open source archival quality web crawler

Heritrix is the Internet Archive's open-source, extensible, web-scale, archival-quality webcrawler project. The Internet Archive started Heritrix development in the early part of 2003. The intention was to develop a crawler for the specific purpose of archiving websites and to support multiple different use cases including focused and broadcrawling. The software is open source to encourage collaboration and joint development across institutions with similar needs. A pluggable, extensible architecture facilitates customization and outside contribution. Now, after over a year of development, the Internet Archive and other institutions are using Heritrix to perform focused and increasingly broad crawls.
Relationship between habitual physical activity and variability of cardiac frequency in women with type 2 diabetes

Among non-communicable chronic diseases, type 2 diabetes mellitus (DM2) stands out for its morbidity and mortality as a risk factor for circulatory system disorders [1]. DM2 is strongly related to mobility limitations and reduced autonomy to perform daily life tasks, especially in older people [2] thus contributing to a reduction in the pattern of habitual physical activity and increased physical inactivity. In women, the highest prevalence of DM2 is also related to menopause, which produces drastic changes in body composition, metabolic profile and hormonal synthesis [3]. In addition, in the patient Diabetic heart rate variability (HRV) is reduced, which suggests the dysfunction of cardiac autonomic regulation, which has previously been shown to be associated with increased risk of adverse cardiac events [4].
Reshaping perioperative nursing practice to get the job done: A constructivist grounded theory study

An estimated 234 million operations are performed in hospitals each year and complications of surgery are common and often preventable1. The rates of complications vary between studies with reports of perioperative death rates of between 0.4 and 0.8 per cent and rates of complications between 3 and 17 per cent. Adverse events can lead to patient disability, death, or increased length of stay, imposing a significant burden on the health care system, patients and their families. Perioperative nurses have a key role in securing patient safety and preventing mistakes and these are recognised as both the nurses’ responsibility and within their locus of control. Research and evidence based actions to minimise the risk of patient harm inform the standards developed by the Australian College of Perioperative Nurses. These standards are closely aligned with similar standards in the UK, US and Canada and represent the accepted standard of professional practice for perioperative nurses in Australia.
Standards in der klinischen Medizin

Abstract Standard operating procedures (SOP) in hospital care have the potential to improve treatment quality and transparency. However, after arriving at the decision to generate a SOP for the own hospital or ward, the upcoming question is often, how to start? The present article tries to give some interdisciplinary guidance about reasonable structures and contents of SOPs that could be understood as a basic matrix for individual work.
Erp Usability Issues From The User And Expert Perspectives1

Enterprise Resource Planning (ERP) s-vstems are used for streamlining the jlow of business processes and information throughout the organization. While indusby reliance on these systena has been on the rise, the notorious challenges they impose on their users can severely hinder their successful adoption and use. The scope and comple.xi@ of their furzctionality can be overwhelming, but ERP systems @pically provide little in the way of guidance or support. Understanding the speciJic trsability problems experienced by users is essential to the development of more usable systems, yet research in this area has been limited. In this study, we investigate how negative "critical incidents" (i.e., serious breakdowns in human-compztter interactions) encountered by users can improve our knowledge and understanding of ERP usability problems. A laboratoiy-based empirical usability evaluation of a popular ERP system was conducted using both user-reported and expert-observed critical incidents. Having users report on usability issues as they happen provides richer details than are typically available from surveys or interviews alone. Augmenting those accozrnts with expert observations of user-system interactions yields a deeper understanding of the types of usability issues that must be addressed.
Clinical, laboratory and ultrasound profile of patients with thyroid cysts

Introduction: Thyroid nodules are very frequent in the general population, affecting about 6% of adult women and 2% of men. An accurate ultra-sonographic evaluation shows that approximately two thirds of all women and one third of all men have small nodules in their glands. True simple thyroid cysts originating from benign epithelial cells are rare. Most cystic nodules are partially solid structures with cystic degeneration (mixed or complex nodules). The clinical-laboratory characteristics of solid or complex thyroid nodules are well known because of their possible association with malignancy, but the characteristics of simple cystic nodules have not been fully determined.
Online optimization of an engine controller by means of a genetic algorithm using history of search

In the present paper, online optimization of an engine controller by means of genetic algorithms (GA) is discussed. In optimization of real complex systems through experiments and computer simulation using random variables, optimization methods must cope with uncertainty of objective function and limitation of possible number of evaluation. Sano et al. (2000) proposed a GA utilizing history of search (GA with memory-based fitness evaluation: MFEGA) so as to reduce the number of fitness evaluation for such applications of GA. In the proposed method, the value of fitness function at a novel search point is estimated not only by the sampled fitness value at that point, but also by utilizing the fitness values of individuals stored in the history of search. In the present paper, this method is applied to online optimization of an engine controller for vehicles. Computer experiments using an engine simulator show that the proposed method outperforms conventional GAs both in convergence speed and accuracy of solution under fluctuation of fitness evaluation.

Fuzzy multiobjective decision making on modeled VLSI architecture concepts

This paper discusses a novel approach for the support of decisions on alternative architectural concepts. Multiple objectives for cost and performance are applied. Analytical performance models have been extended by fuzzy arithmetic. Known analytical efficiency measures are generalized by a fuzzy multiobjective decision making approach. The proposed modeling technique has been implemented by a new tool, the VSP Decision Program, which flexibly supports the high-level specification and evaluation using various performance models.
Antioxidant therapy in cardiovascular diseases: still a matter of debate

Reactive Oxygen Species (ROS) are highly reactive chemical species, which are responsible for oxidative stress inside the cell. They are mainly generated in vascular cells by NAD(P)H oxidases, uncoupled endothelial nitric oxide (NO) synthase, and other enzymatic sources, or as a byproduct of mitochondrial respiration. Imbalanced production of ROS lead to exacerbation of pathophysiological processes in both humans and in animal models [1]. For example, in a number of cardiovascular pathologies, including hypertension, atherosclerosis, myocardial infarction, ischemia/reperfusion injury, and restenosis after angioplasty or venous bypass grafting, excessive production of reactive oxygen species has been implicated to play an important role [2]. As ROS can be neutralized by antioxidants, many studies proposed antioxidants as a treatment option in ameliorating diseases.

INTERACTION OF DIFFERENT MODULES IN DEPTH PERCEPTION.

The interaction of modules for depth perception was studied psychophysically by measuring the perceived depth of computer generated images showing simple solid objects with different combinations of depth cues. Accumulation of information from shading and stereo and vetoing of depth from shading by edge information have been found. Cooperativity and other types of interactions are discussed. If intensity edges are missing, as in smooth-shaded surfaces, the image intensities themselves could be used for stereo matching. Matching primitives other than edges were studied in additional experiments. The results are compared with computer vision algorithms for both single modules and their integration for 3D-vision.
Quality of life among chronic disease patients

Quality Of Life (QOL) has become an increasingly attractive subject in recent decades, drawing attention from both enthusiasts and researchers [1-3]. But what is quality of life in fact? Is it defined by our looks? Financial state? Nature or nurture? In truth, people define it by all of the above and many more [4]. This study, however, intentionally wishes to define the quality of life through the narrow focus lens of the chronic medicine field. There is a good reason why the quality of life of chronic patients has been a popular field of research in the last 20 years. Non-communicable chronic diseases such as cancer, stroke, diabetes, HIV and more have been found to take a staggering annual death toll of 38 million [5]. It comes with little surprise then, that the HRQOL (Health Related Quality Of Life) of people suffering from such maladies was vastly studied and documented. The research into chronic patients’ HRQOL is believed to significantly benefit their bodies and minds. After all, such writings are meant to expose the means to maximize the patient’s’ quality of life. These means may alleviate the conditions which commonly restrict patients’ careerrelated tasks and their daily activities as well as affording them an extended period of independence [6].
Implementation of an RDMA verbs driver for GridFTP

GridFTP is used by researchers to move large data-sets across grid networks. Its benefits include data striping, multiple parallel data channels, and check-pointing. Like traditional FTP, GridFTP separates the control channel from the data channel, but also includes extensions to allow for third-party control of the transfer. GridFTP is one component of the Globus Toolkit, a software system designed to allow researchers to easily adapt, extend, and modify GridFTP and other tools to meet their specific needs. The eXtensible Input/ Output (XIO) component, which provides common and logging libraries as well as built-in transport drivers such as TCP and UDP, defines the architecture and API used for implementing new drivers. Remote Direct Memory Access, or RDMA, is a network communication architecture which defines a number of features not available with traditional sockets based communication. With RDMA all I/O operations are offloaded to hardware. Combined with the use of registered memory, this eliminates the intermediate copying of data to kernel buffers as is done with TCP. This results in a significant reduction in latency and CPU overhead because the kernel TCP/IP stack is not used. The RDMA architecture is implemented with InfiniBand cables and interface cards, or with Ethernet cables and RoCE or iWARP interface cards. This thesis funded in part by National Science Foundation Grant OCI-1127228, and describes the implementation of a new Globus Toolkit XIO driver which uses the RDMA Verbs API to drive network communication. Unlike other XIO drivers, the RDMA driver will not produce an intermediate copy of data prior to transmission over the network, therefore taking advantage of the full capabilities of RDMA. The work presented here describes the motivation, implementation, and various challenges and solutions associated with implementing a new XIO driver for RDMA, as well as giving an overview of its effectiveness when compared with TCP.
Ebola virus: an updated review on immunity and vaccine

Ebola virus (EBOV) derived its name from the Ebola River in Democratic Republic of Congo (DRC) (formerly Zaire) where the first Ebola virus disease (EVD) outbreak was observed in 1976 [1]. EBOV is enveloped, non-segmented, negative-stranded RNA virus containing filamentous virion which belongs to the family Filoviridae. EVD is caused by filamentous EBOV associated with mortality rates between 25 and 90 % [2]. The clinical symptoms of this disease are non-specific and flu-like, such as high fever, headache and myalgia at the early stage [3]. The symptoms also included diarrhea and vomiting when the large outbreak occurs in West Africa (2014 to present) [4]. Immune cell disorders are associated at the late stage of this disease such as, diffuse intravascular coagulopathy caused by coagulation and neutrophilia disorders [5-7]. Humans may acquire the disease by close contact with biological fluids of the infected animals or patients. During the acute phase of illness, EBOV has been detected in different body fluids including breast milk, saliva, semen, stool, sweat, tears and urine [8-12]. EBOV has been isolated from urine (9 days) and from aqueous humor (9 weeks) after the virus was cleared from plasma [13].
