Performance enhancement of grid-interfaced inverter using intelligent controller

The high-performance grid-interfaced inverters are in demand as they are rapidly used in renewable energy systems. The main objective of grid-interfaced inverters is to inject high-quality active and reactive power with sinusoidal current. Many control schemes have been proposed earlier in the literature, but the operation under parametric uncertainties has not been given much attention. In this article, an adaptive network–based fuzzy inference control algorithm for a three-phase grid-interfaced inverter under parametric uncertainties is proposed. The main purpose of the proposed technique is to enhance the response time, decrease the steady-state oscillation in the injected active and reactive power and enhance the power quality even with parametric uncertainties. For assessment and evaluation reason, the conventional proportional–integral control is compared with the proposed controller. For a fair comparison, the gain setting for the proportional–integral control is obtained by Particle swarm optimization algorithm. The suggested system is developed and simulated in MATLAB/Simulink. Simulation results demonstrate that both the controllers work well to regulate the powers to required values, even with parametric variations. However, the proposed control demonstrates superiority in comparison to conventional proportional–integral control in terms of speedy response, decreased steady-state fluctuations, better power quality and increased robustness. The rise time and fluctuations in the per-unit active and reactive power are much less with the proposed control. Total harmonic distortion of the injected current and grid current are significantly better than the conventional proportional–integral control.
Phase‐matched frequency doubling in an aluminum nitride waveguide with a tunable laser source

Frequency doubling is observed in an aluminum nitride waveguide deposited by dc reactive magnetron sputtering. Phase‐matching conditions are obtained by tuning the wavelength of an optical parametric oscillator pumped by a pulsed Nd:YAG laser. The maximum second harmonic generation efficiency is obtained for the TM0(ω)‐TM2(2ω) conversion process and is estimated to be around 4×10−8 W−1.
MECHANISMS DRIVING TERRITORIAL AND SOCIAL BEHAVIOR IN A COOPERATIVE CARNIVORE

Territorial behavior is a fundamental and conspicuous behavior for numerous species, but the mechanisms driving territory selection remain uncertain. We developed a mechanistic, spatially-explicit, individual-based model to better understand how and why animals select particular territories. Theory and empirical precedent indicate that many animals select territories economically to satisfy resource requirements for survival and reproduction, based on the benefits of food resources and costs of competition and travel. The cost of competition may vary by competitive ability, and for some animals the cost of predation risk may also drive territory selection. Habitat structure, resource requirements, conspecific density, and predator distribution and abundance are likely to further influence territorial behavior. Through simulations, we developed numerous predictions for what may be observed empirically if these hypotheses explain the mechanisms driving territory selection. Predictions arose from interactions among competitors who attempted to maintain optimal territories with respect to the economic value of patches. We found that increasingly clumped or abundant food resources are predicted to result on average in smaller territories with more overlap. Territories are predicted to compress with increasing population density, and less competitive territory-holders are generally predicted to have larger territories. Territory size and overlap are predicted to show an n-shaped parabolic response to increases in predator densities, and territories are predicted to be larger where predators are more clumped in distribution. A literature review showed that our model’s predictions are largely consistent with empirical observations, providing support for the hypotheses of how and why animals select particular territories.
Functional and whole regression-based genome-wide association analyses for weight measurements of chicken eggs

In genomic studies, complex traits can be modelled using repeated measures, thereby gaining a better understanding of the underlying biology. An increased number of measurements per individual might reduce measurement noise, thus increasing the likelihood of detecting true genomic signals. Here we aimed to predict genomic signals over a logistic curve referring to multiple underlying genetic architectures, for both simulated and longitudinal egg weight datasets. The chicken data were obtained from 92 sires and 801 dams of an 11th generation pure line, resulting in data from 1078 hens. We analysed longitudinal measurements of egg weights with 294,705 single nucleotide polymorphisms (SNPs). We found that a single regression-based functional genome-wide association study (fGWAS) could be useful for manipulating dynamic egg weight over the entire laying period based on a moderate to major effect gene. The fGWAS SNPs associated with the egg weight were located on chromosome 1 close to the gene DLEU7, which has a role in regulating ovary weight in chickens. The SNPs were detected based on the absolute effect sizes using whole regression Bayesian models. This approach is likely to be useful for predicting polygenic risk scores and/or genomic breeding values during the genomic selection/ gene editing for longitudinal egg weight measurements.
Spoken and Written Language as Medium of Communication: A Self-reflection

Speaking and writing are the most important communicative tools among human beings. While speaking is considered to be older and more widely employed, spoken and written language have not been treated equally. Spoken language is seen as the natural productive tool among people that is more common and normal, whereas written language is seen as being intricate and complicated due to its extensive rules. Therefore, spoken language has attracted the attention of researchers to a greater extent compared to written language due to the belief that spoken language has primacy over written language. This paper is an attempt to shed some light on these two communicative elements and the differences between them. A self-reflection, based on Dewey’s (1997) ground-breaking work, is presented in terms of when/where spoken or written language is more appropriate as a medium of communication. It can be argued, therefore, that both speaking and writing are important means of communication without prioritising one over the other; yet, conventions are the real indicators as to which medium of communication is more appropriate.

30 Background: Renal cell carcinoma (RCC) is a lethal neoplasia. Data from Latin America are scarce, and the distinct ethnic origins of this population could affect predictive or prognostic factors. 31 32 Objective: We aim to describe a large cohort of non-metastatic renal cell carcinoma, identifying the demographic, clinical, and pathological prognostic factors for survival. 33
UAV Visual Servoing Navigation in Sparsely Populated Environments

This paper presents a novel approach based on deep neural networks for autonomous navigation of a quad-copter UAV in a sparsely populated environment. Images from the video camera mounted on the UAV are split, emulating a compounded eye, and processed by deep neural networks that calculate the probability that each image con-tains a wind turbine object. Then, these probabilities are used as inputs to a vision servoing system that controls the drone’s navigation movements. Our experiments show that our approach produces relatively sta-ble movements in the UAV, allowing it to ﬁnd and navigate autonomously towards a wind turbine.
Implementation of nursing process in Ethiopia and its association with working environment and knowledge: a systematic review and meta-analysis

Background: Nursing Process is a scientific problem solving approach to direct nurses in caring for clients effectively and to improve quality of health care service. In Ethiopia the national pooled prevalence of implementation of nursing process remains unknown. Hence the objective of this systematic review and meta-analysis was to estimate the level of implementation of nursing process and it association with knowledge and working environment. Methods: PubMed Scopus Cochrane Library Google Scholar PsycINFO and CINAHL were systematically searched online to retrieve related articles. The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guideline was followed. To investigate heterogeneity across the included studies I2 test was employed. Publication bias was examined using funnel plot and Egger regression test statistic. The random-effect model was fitted to estimate the summary effects and odds ratios (ORs). All statistical analysis was done using STATA version 14 software for windows. Results: Seven studies which comprises of 1268 participants were included in this meta-analysis. The estimated pooled prevalence of implementation of nursing process in Ethiopia was 42.44% (95% CI (36.91-47.97%)). Based on the subgroup analysis the highest implementation of nursing process was observed sample size greater than or equals to two hundred 44.69% (95% CI: 35.34, 54.04). Nurses who have been work in the stressful environment [(OR 0.41 95%CI (0.08-2.12)] and having good knowledge about nursing process [(OR 2.44 95%CI (0.34,17.34)] was not significant associated with the implementation of nursing process. Conclusion: The overall implementation of nursing process in Ethiopia is relatively low. Nurses who have been work in the stressful environment have less likely implement nursing process. On the other hand Nurses who had good knowledge on nursing process were more likely to implement nursing process. Therefore, policymakers (FMOH) and other concerned body need give special attention to improve the implementation of nursing process.

Successful control of outbreak caused by clonally related extensively-resistant Acinetobacter baumannii in an intensive care unit

Objective: Worldwide drug resistance in Acinetobacter baumannii is on the rise. We report outbreak of extensivelyresistant (XDR) A. baumannii in a medical intensive care unit (MICU) at a tertiary care referral hospital in Pakistan. During subsequent survey, 10 extensively-resistant A. baumannii were isolated from 8 environmental samples and hands of 2 healthcare workers (HCWs). Methods: In January 2013, XDR A. baumannii (Ab1, Ab2, and Ab3) were isolated from tracheal aspirate, blood and sputum of three patients with ventilator associated pneumonia. The isolates were resistant to piperacillin, ampicillinsulbactam, piperacillin-tazobactam, ticarcillin-clavulanic acid, ceftazidime, cefipime, ceftriaxone, imipenem, meropenem, gentamicin, amikacin, doxycycline, minocycline, ciprofloxacin and trimethoprim-sulphamethoxazole. Pulsed Field Gel Electrophoresis (PFGE) revealed that isolates from HCWs were similar to the genotype initially isolated from patients’ samples. Results: Control of the outbreak was attained with requisite infection control practices and fumigation of the Medical ICU unit. From February 2013 to April 2013 there were no new cases of extensively-resistant isolates in medical ICU. However, two more cases with similar antibiogram MICs and genotype of extensively-resistant isolates emerged in June 2013 from the same MICU. Conclusion: Stringent infection control measures were implemented this time with continuous monitoring and regular surveillance. Follow up for the next two years has been successful as no clustering of XDR A. baumannii were detected from medical and surgical ICUs. J Microbiol Infect Dis 2017; 7(1): 1-6

A bulk suppressed low loss TDNM-IF filter using LBO substrate

This paper describes for bulk suppression of SPUDT filter on LBO substrate. To suppress the bulk response, new advanced dual track filter is developed. The main track and sub track are identical structure, but phase-inversion each other. To prevent canceling the SAW responses of main track and sub track, all over of the sub track are covered with the absorber that avoid excite the SAW. However, sub track generates bulk acoustic wave (BAW) that are phase inversion against main track. Consequently, the BAW responses are canceled out for dual track without degrading SAW response. The developed 157MHz TDMA-IF filter is installed 5/spl times/7mm sized ceramic package, and achieves low loss of 4.5dB. Regarding to the bulk spurious, it is improved about 10dB comparing with conventional one track type SPUDT using LBO substrate, and its out of band rejection level is better than 50dB in 185-500MHz frequency range.
Distinguishing the Many Varieties of Criterion-referenced Tests

This paper provides a framework for integrating the many conceptions of criterion-referenced testing. The categories of the scheme are illustrated by examples of criterion-referenced tests that have been developed between the years 1864 and 1978. The scheme provides one way to show how various conceptualizations of criterion-referenced testing are both similar to and different from each other.
Effect of Health Educational Intervention on Knowledge and Perceptions of Asthma among Secondary School Students in Ile- Ife, South-West, Nigeria

Asthma is a major public health problem among adolescents with significant functional disability. Inadequate knowledge and poor perceptions of the disease are highly contributory to its impact. Patients’ education is vital in addressing this challenge. The study assessed the level of knowledge and perceptions of asthma and the impact of asthma health education programme among a group of the secondary school students in IleIfe, Nigeria. It is a quasiexperimental design study which used a pre-tested 71item, purpose designed, selfadministered questionnaires to collect information on knowledge and perceptions of the respondents on asthma before and after intervention. Data were collated and analyzed based on descriptive and inferential study design. The results of this study showed that perceptions and knowledge of asthma were poor among the group. There was a significant difference in the pretest and posttest knowledge and perceptions scores of asthma of the secondary school students in the intervention group following health education programme intervention. In addition, the results showed that there was a significant change in knowledge and perceptions of asthma overtime for the participants in the intervention group, over a period of 1 week, 3 weeks and over a period of 6 weeks. We concluded that health educational intervention has significant positive effect on knowledge and perceptions of asthma among secondary school students in IleIfe, Osun State, South West, Nigeria.
Paguroid anomurans from the upper Tithonian–lower Berriasian of Štramberk, Moravia (Czech Republic)

Subsequent to a preliminary report on a handful of paguroid remains from the Tithonian (uppermost Jurassic) to lower Berriasian (Lower Cretaceous) Štramberk Limestone in Moravia (eastern Czech Republic), published in 2013, several field campaigns were organised by our research team during the summers of 2012–2015 and 2018. These resulted in the recovery of additional paguroid shields (or, anterior carapaces) that form the basis of the present study. The currently available material documents a diverse paguroid fauna. In fact, it ranks
Investors' trading behaviour and stock market volatility during crisis periods: A dual long‐memory model for the Korean Stock Exchange

This study examines the impact of investors’ buy and sell trades on Korean stock market volatility across two crisis events, the Asian crisis of 1997 and the 2008 global financial crash. We investigate the trading behaviour of domestic vs. foreign and institutional vs. individual investors. Our results suggest that the buy and sell trades have an asymmetric effect on volatility that depends on the type of investor trading and on the phase of the business cycle. Buy orders appear to be more informative than sell orders since they mostly lower volatility in the pre-crisis periods, while sell and post-crisis buy trades affect volatility positively regardless of who trades (institutional or individual investors) and on what information (member, non-member). Most importantly, decomposing total buy and sell trades into trader-type categories reveals that some institutional investors are more informed traders that stabilize the market compared to individuals that always increase volatility. Foreign investors reduce volatility with their purchases and total trading activity in the whole Asian crisis sample, but only in the pre-crisis period before the recent global financial turmoil.
Recovery Colleges; how effective are they?

Purpose Recovery Colleges are education-based mental health resources, utilising practitioner and lived experience expertise, promoting skills to enhance student independence. The purpose of this paper is to evaluate the impact of engagement with a Recovery College in Northern England on student wellbeing. Design/methodology/approach Feedback questionnaires were analysed from 89 students attending the Recovery College. Short Warwick-Edinburgh Mental Wellbeing Scale (SWEMBS) and “Empower Flower” (a measure of personal resources) data for 56 students were compared pre- and post-attendance at courses. Findings The SWEMBS and Empower Flower indicated improvements in wellbeing and personal resources pre- to post-attendance at Recovery College courses. Satisfaction with the service was high. Students saw the service as unique, accepting and enabling. Students noted they developed a sense of hope, confidence and aspirations. They related this to practical changes, e.g. increasing work-related activity and decreasing service use. Research limitations/implications This research suggests that there is a need for further evaluation of the unique contribution that Recovery Colleges can make to mental wellbeing, and the mechanisms involved in promoting the process of recovery. Practical implications The Recovery College may be a cost-effective way to provide a supportive recovery-orientated environment which promotes students’ ability to build self-confidence and skills, enabling them to connect with others and progress towards independence and valued goals. This complements more traditional mental health services. Originality/value This paper reports on an area of mental health development where there is very limited research, adding valuable data to the literature.
Direct-ORB-SLAM: Direct Monocular ORB-SLAM

Simultaneous Localization and Mapping (SLAM) plays an important role in the computer vision and robotics field. The well-known ORB-SLAM extracts ORB features and uses feature matching to estimate the camera pose and construct a sparse map. However, the features extracted in the common frame (relative to the keyframe) are not used again except in this camera pose estimation stage, which will cause the waste of computation resources. In this work, we propose a new SLAM framework, i.e. Direct-ORB-SLAM. It uses image intensity for data association in common frames to avoid the redundant computations and performs the relocalization and loop closure detection in ORB-SLAM2 for keyframes. The photometric calibration is also employed to benefit for accuracy and robustness. The popular public dataset EuRoC is adopted to approve the efficiency of proposed method. Results indicate that the proposed Direct-ORB-SLAM algorithm runs two times faster than the well-known ORB-SLAM at the expense of a slight reduction in accuracy.
A Modular Fast Cell-to-Cell Battery Voltage Equalizer

Voltage equalizers are used to ensure that there is no overcharge or overdischarge of cells in series-connected battery stacks. A novel fast multicell-to-multicell voltage equalizer topology is proposed in this article. The equalizer has a modular structure consisting of one half-bridge converter leg, one inductor, and one capacitor for each battery. Only battery voltage sensing is sufficient for controlling the equalizer. The proposed equalizer can transfer charge from multiple batteries to multiple batteries in a string simultaneously. The equalization current does not depend on the battery voltage differences and, hence does not reduce as the battery voltages approach each other during voltage equalization. A modularization method is proposed for this topology with two additional passive elements per module. This method provides a direct charge transfer path from any cell in one module to any cell in another module. Thus, the equalization time does not increase with the number of modules. The proposed topology is theoretically analyzed and experimentally verified with a prototype equalizer in a series-connected lead-acid battery string, a Li-ion battery string, and a hybrid ultracapacitor string. The proposed modularization method is verified experimentally with two modules tested together in a battery string.
Assessing the Social Media Maturity of a Community Radio Station: The Case of Rhodes Music Radio in South Africa

Social media has become a major factor within the operations and functions of radio stations. This study used a social media maturity model (SMMM), developed from available literature, to assess the social media maturity of a South Africa community radio station, Rhodes Music Radio (RMR). The study found that RMR had a level 3 rating on a 5-level maturity scale, indicating that it was quite, but not yet fully, mature in its social media use. In addition to outlining the research and its findings, this article makes recommendations for how the station could increase the maturity of its social media use.
