CONTROL STRATEGIES FOR GENERATOR SIDE CONVERTER OF DIRECT DRIVEN WIND ENERGY CONVERSION SYSTEM

This paper presents a comparative analysis of different controlling strategies for a direct driven PMSG wind energy power system (WECS) connected to the grid. The DC link voltage is controlled by the generator side converter by using a current mode PWM controller and fixed frequency sliding mode controller (FFSMC). The Grid side converter (GSC) controls the grid active power for maximum power point tracking. The validity of the proposed control schemes has been verified by simulation. The merits of the proposed control scheme are, it does not require the measurement of wind velocity, PMSG stator currents are sinusoidal and power injected into the grid at unity power factor. Modeling of Wind turbine, PMSG, controlling of generator side switch mode converter, controlling of the GSC and Simulation results are presented. Simulation is done in MATLAB/POWERSYSTEM environment.
Helping Mothers Defend their Decision to Breastfeed

Very little research has examined specific approaches to help people resist negative messages about health beliefs and behaviors. One approach to helping people resist persuasion and adhere to therapeutic regimens and health guidelines is the Inoculation Theory of Resistance to Influence (IT). This paper presents an overview of the theory and reviews studies that have applied an inoculation treatment in a health context. Primary research reports of intervention studies based on inoculation theory were identified using electronic database searches, bibliographic mining, and citation searches. Studies from 1992 to 2014 were included in the review. A number of so-called IT studies were excluded from the review because the intervention did not contain the essential constructs of an inoculation treatment forewarning of impending attack on attitude and individual susceptibility to attitude change, followed by presentation of a weak persuasive argument that is promptly refuted. Only five studies met the selection criteria. The studies were in the following categories: smoking, alcohol, risky sexual behavior, and nutritional advertisements. Across these studies, IT was found to preserve health beliefs but the studies were limited to client populations who are more easily dissuaded, such as adolescents and young adults. Findings suggest that IT holds promise for improving health behavior but more research is needed to determine its impact with other study populations. The Use of Inoculation Treatment to Preserve Positive Health Beliefs Maintaining positive health beliefs can help individuals adhere to health guidelines for health promotion or therapeutic regimens for disease prevention and management. Health beliefs are affected by gender, age, ethnicity, agency, values, and other circumstances of individuals.
Mentoring New Special Education Directors Through a Supplemental Preparation Program in Massachusetts

The purpose of this study was collect and analyze the perceptions of special education directors who attended a state funded Leadership Academy for new Special Education Directors in Massachusetts. The participants were member of the Accept Collaborative Leadership Academy (ACLA) cohorts 9 (2012) & 10 (2013). The two research questions for this study were: (1) what benefits were perceived by director’s who participated in ACLA? (2) What is the perceived benefit to members of a Community of Practice (CoP) that developed as a result of ACLA? The problem of practice focused on the challenges new special education directors face in their first years in the position and the need for a network of peer support. This qualitative study consisted of three focus groups made up of current Massachusetts special education directors who had attended ACLA. The theoretical framework chosen was Community of Practice (CoP) theory. The literature review contained summaries of the literature on the following topics: the role of the special education director, certification, standards for special education directors, preparation programs, supplemental training, mentoring and cohorts. Data was gleaned from focus group transcripts, demographic data and a topic/speaker ranking activity completed by the special education directors. The study had six findings: (1) Directors who participated in focus group interviews and by submitting documents were extremely grateful for their experience in ACLA and the continued benefit of participating in reunions and CoP meetings over the years; (2) While individual mentoring was not the focus of the research questions, mentorship was discussed frequently in all focus groups. Directors spoke candidly about the lack of support from their districts such as not being assigned a mentor, or being assigned a mentor who did not have the
Modeling of Solar PV system under Partial Shading using Particle Swarm Optimization based MPPT

Ujjwala Rai1 1 Assistant Professor, Dept. EED, SGSITS College, MP, INDIA ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract This work presents the effects of changing environmental conditions on the solar photovoltaic energy conversion system. Partial shading causes oscillations in output characteristics of the PV (photovoltaic) array and distracts the system to track MPP (maximum power point). In this paper, generalized approximate model of the solar cell is implemented using MATLAB/Simulink software package. In order to track maximum power efficiently from the PV array, evolutionary search technique PSO (particle swarm optimization) algorithm is used. Finally the developed model for PV array is interfaced with DC/DC boost converter using SimPowerSystems tool box to extract stepped up voltage from solar array. The duty cycle of the converter is controlled by the MPPT algorithm and PI (Proportional integral) controller. The PV array model is developed and simulated to produce higher output voltage under partial shading conditions.

The scope of the scheme is limited to three fingers only and also for high security purpose where it is very important to keep tight security like military application, forensic labs, civilian, banking applications, etc. -The increased level of effective security control and transaction fraud in the world of electronic and internet commerce, demands for highly secured identification and personal verification systems.
Privacy-Preserving in Cloud Computing Using Single Sign-On

- Cloud computing is emerging as a prevalent data interactive paradigm to realize multiple users data remotely stored in an online cloud server. The solutions mainly focus on the authentication to realize that a user’s privative data cannot be un authorized accessed, but neglect a subtle privacy issue during a user challenging the cloud server to request other users for data sharing. This shared authority based directory services authentication protocol (SAPA) to address above privacy issue for cloud storage. Shared access authority is achieved by LDAP authentication for create many directory services. Attribute based access control is adopted to realize that the user can only access its own data fields. AE Attribute encryption is applied by the cloud server to store and retrieve data, and to provide data sharing among the multiple users. universal composability (UC) model is established to prove that the SAPA theoretically has the design correctness. It indicates that the proposed protocol realizing privacy-preserving data access authority sharing is attractive for multi-user collaborative cloud applications.

Interprétation du cortisol libre plasmatique en pratique clinique

L'exploration de la fonction glucocorticoide, fondee sur la cortisolemie totale et la cortisolurie, reste limitee par un certain nombre d'erreurs systematiques qui peuvent etre evitees par la determination de la fraction libre du cortisol plasmatique (CLP), la seule biologiquement active. Le but de ce travail est de definir l'intervalle de confiance de ce parametre, dose a l'aide d'une methode radioimmunologique avec ultrafiltration, chez des sujets temoins et dans diverses situations physiologiques, dont la contraception hormonale et la grossesse, et pathologiques (obesite, hypercorticisme et hypocorticisme). Les resultats mettent en evidence un CLP plus eleve chez les hommes que chez les femmes (13,4 ± 6,1 contre 10,7 ± 4,3 ng/ml; p < 0,05). L'intervalle de confiance propose est de 4,5 a 24,5 ng/ml. Le CLP moyen est discretement augmente au cours de l'obesite, mais l'intervalle de confiance defini chez les temoins reste valable. La sensibilite et la specificite du CLP sont superieures a celles du cortisol total et de la cortisolurie de 24 heures. Le dosage du CLP devrait desormais remplacer celui du cortisol, total dont les informations sont trop souvent distractives et insuffisamment discriminantes

Medical Document Classification from OHSUMED Dataset

- Investigation of biological databases is not straight forward and generically needs identification of Medical Document Classification (MDC) based on hierarchy and relationship between different strata (ontogeny). Thus, MDC remains as a challenging effort. Popularly, earlier text classification has applied flat classifier. However, our research aims to show the text classification in which we opt to assess the hierarchical organization of classes or categories. In order to fulfill the aim of our research, we are considering the human disease hierarchical structure of human disease ontology with the help of simple relation from biomedical text abstracts and the ontology learning. We conducted experiments to evaluate the effects of different representations by measuring the change in classification performance with MEDLINE documents from the OHSUMED dataset. This research suggest a hierarchical classification method employing the hierarchical concept structure for classifying biomedical text abstracts by using Hidden Markov Model method (HMM). Present study demonstrates how a large number of biomedical articles are divided into quite a few subgroups in a hierarchy describing ontogeny.
Physiological and Behavioral Responses of Dairy Cows which Milked with Portable parlor

In normal use, milking parlor can cause the release of oxytocin through neuroendocrine reflex, but the use of milking parlor sometimes cause stress and lead to a decrease in milk production. In Indonesia at this time, traditional milking by hand is still widely used by dairy farmers. The purpose of this study is to investigate the use of milking parlor to the physiological and behavioral responses of dairy cows through oxytocin levels in serum. This study used 20 multiparous lactating dairy cows aged 3-6 years. The collection of blood samples are carried out at different times: before the use of milking parlor (A), 50 minutes (B) and 100 minutes post-installation milking parlor (C). The behavior of dairy cows observed by kicking or stepping. Serum cortisol levels were measured using ELISA technique. The results showed that there was no significant difference (p> 0.05) milking time on serum cortisol levels of three groups treatments. Cortisol levels in the three treatment groups were 7,07 ± 0,61 ng/mL; 7,77 ± 0,81 ng/mL; and 5,88 ± 0,74 ng/mL, respectively. Observation of the behavior of dairy cows using a milking parlor showed that 35% of cows pose a step, 10% raises kicking motion and the rest did not cause stepping or kicking. Pearson correlation test showed that there was no correlation between behavior response and cortisol serum levels (p>0.05). In conclusion, the use of milking parlor portable do not affect serum cortisol levels and the comfort of dairy cows.
Short Term Effect of Acupuncture in Chronic

Low back pain (LBP) is one of the most common musculoskeletal disorders. The data collected by a National Ambulatory Medical Care Survey (NAMCS) suggests that 2.3% of visits to the physician are attributed to LBP, which has changed little since 1990s [1]. If serious spinal pathologies are excluded, most of the cases presented in the primary care are non-specific LBP [2]. It is one of the main causes of disability in working adults, even though it responds to a wide spectrum of interventions [3,4]. In UK, the annual total cost of LBP to the economy is estimated to be £12.3 billion [5]. According to the NICE guidelines, one third of the UK’s population is affected by LBP [6].

A Typical Framework for Forecasting and Trading Time Series Data Using Functional Link Artificial Neural Network

— Prediction of time series data, whether the data related to the stock market or exchange rate is of enormous interest to traders or investors due to high profit in trading. Thus the prediction of time series data indices and its study are important to discover whether the next day’s closing price would increase or decrease. For that reason, we construct a framework for predicting time series data by using a low complexity, adaptive functional link artificial neural network (FLANN) over a time frame varies from one day ahead to several weeks. The FLANN is basically a single layer structure in which non-linearity is introduced by enhancing the input pattern with nonlinear functional expansion. The architecture of FLANN will be trained with the working principle of heuristic stochastic algorithms to achieve the best forecasting and classification to increase in accuracy of prediction and decrease in training time. Heuristic and Stochastic refers to an experience-based technique for problem solving, learning, and discovery that find a solution which is not guaranteed to be optimal, but good enough for a given set of goals and helps in minimizing errors. The proposed project is based on all these parameters which will predict time series data using FLANN trained by heuristic stochastic algorithm. Extensive computer simulations will be carried out and it is compared with traditional artificial neural network to observe the accuracy of the FLANN model.

Study of Changes in Activity of Wheat Antioxidant Enzymes under Stress Residue of Imazethapyr Herbicide

In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of herbicide) per kilogram of soil. The analysis of variance showed that the content of the main and auxiliary pigments of leaf, proline, sugar content, protein, activity of catalase enzymes, peroxidase, polyphenol oxidase, root and shoot dry weight were significantly affected by herbicide. The results showed the Imazethapyr herbicide stopped the production of valine leucine and isoleucine amino acids. As a result, the rapid reduction in the volume of these amino acids led to a reduction in protein synthesis in wheat plant. Therefore, the application of doses of 0.011, 0.022, 0.033 and 0.044 micrograms of herbicides decreased 14, 26, 44 and 47 percent of leaf protein content, respectively, compared with control treatment. Further, theapplication of these doses resulted in the reduction of 2.8, 5, 27 and 64% of activity of catalase enzyme, 3.5, 39, 49 and 52% peroxidase enzyme activity and 13, 24, 35 and 46% activity of polyphenol oxidase enzyme, compared with control treatment. The results revealed that Imazethapyr herbicide activates wheat antioxidant enzymes to reduce plant tolerance from damage caused by herbicide residues; therefore, it can be used as a marker or index of herbicide damage rate in physiological research.
