Comparison of RCMV-PWM methods for photovoltaic systems with deadtime effect consideration

In photovoltaic (PV) grid-connected energy conversion systems with no galvanic isolation, PV module parasitic capacitance introduces ground leakage current (common mode current (CMC)) which its amplitude depends on converter topology and pulsewidth modulation (PWM) technique. This paper analyzes and comparisons the performance characteristic of conventional PWM method, space vector PWM (SVPWM) and reduced common mode voltage (RCMV) PWM methods, AZSPWM, NSPWM and RSPWM. The number of switching per periods, voltage linearity, CMC, CMV, harmonic distortion factor (HDF), DC-Link ripple current of each modulation methods are thoroughly investigated by analytical methods and computer simulation. The main objective of this paper is to investigate optimal RCMV PWM methods with considering deadtime effect. This paper aids design engineer in selection of RCMV methods with respect to their applications.
Hardware Implementation of Fast and Robust Star Centroid Extraction With Low Resource Cost

Star trackers measure the attitude of a spacecraft by matching the stars captured by the camera and those stored in the onboard database, whose directions are already known. The information (i.e., location and brightness) on the stars in the captured image must be correctly and timely provided for star recognition. This process is called star centroid extraction. The hardware implementation of the star centroid extraction algorithm using parallel and pipelined architecture is a proper solution to ensuring higher accuracy as well as lower time cost. However, some limits restrict the performance of these kinds of algorithms. For example, faint stars, disturbing objects (e.g., the moon, bright planets, and so on), and noise pixels are not valid stars but resume a large amount of resource. Some irregularly shaped star spots may cause the algorithms to obtain inaccurate results. To solve these problems, this paper proposes a star centroid extraction method implemented on field programmable gate arrays (FPGAs) with a dynamic rooted tree architecture. In contrast to the traditional connected domain segmentation method, this method merges the equivalence table in the process of scanning, such that only one scan of the image is needed. Moreover, this method profits from a strict equivalence merging logic and can deal with various irregularly shaped star spots. Experiments are performed both on PC simulations and FPGA platforms, and results show that this method achieves good performance at a very low resource cost.
Modeling the signal processing of a multi-sonar system to determine interference solutions

M O D E L I N G T H E S I G N A L P R O C E S S I N G O F A M U L T I S O N A R S Y S T E M T O D E T E R M I N E I N T E R F E R E N C E S O L U T I O N S by Brian O'Donnell University of New Hampshire, May, 2009 The quality of a multibeam echo-sounder sonar (ES) signal used in seafloor mapping is degraded by an interfering sidescan sonar (SS) signal. The ES and SS signals occur at approximately the same time, are in the same frequency band, and arrive from approximately the same direction. The ES signal is a 2 ms continuous wave pulse with a first null bandwidth of 1 kHz centered at 187.5 kHz. The interfering SS signal is an 8 ms linear frequency modulated chirp with a bandwidth of 2.5 kHz centered at 183 kHz. The presence and properties of the interfering SS signal are explained using a model of the ES signal processing. Model results as well as spatial and temporal frequency analysis of the recorded ES signal show that most of the interfering SS signal can be removed by zero phase filtering with a 10 tap boxcar filter. This additional filtering reduces the resolution of the multibeam echo-sounder system from 1.318 meters to 1.873 meters. Because this reduction in resolution is not acceptable, the design trade-offs of moving either the ES or SS frequency bands are discussed. Statistical analysis of seafloor detections, before and after the additional frequency filtering shows that there is a difference between filtered and unfiltered detections that is dependent upon the angle of arrival. The unfiltered detections are on average between 0.4% and 1.6% deeper than the towfish altitude of 50 m.
OPINION MINING IN PRODUCT REVIEW SYSTEM USING BIG DATA TECHNOLOGY HADOOP

Product Review System (PRS) is a web application, which takes reviews of consumers in the form of comments, likes, dislikes, star rating about the product as an input and process the data to generate analytics using Apache Mahout on BigData technology Apache Hadoop. Analytics mainly include generating the percentage of positive and negative comments among the posted comments which helps in making quick purchasing decision for consumers, helps in recommending products to similar interested consumers and also helps manufacturers to know the opinion of consumers about their products quickly because , no need to read all the comments posted. This saves the time of both consumers and manufacturers. More accurate analyses may lead to more confident decision making. Better decisions can mean greater operational efficiencies, cost reductions and reduced risk.
Macromodeling CMOS circuits for timing simulation

A macromodeling and timing simulation technique is presented that allows fast and accurate delay calculations for CMOS circuits. This method is well suited for delay calculations of regular structure VLSI circuits, as well as circuits designed from standard cell libraries. Timing models for both logic gate and transmission gate circuit forms are developed. Typical delay times were within 5% for logic gate circuits and 10% for transmission gate circuits when compared with SPICE results. The execution time of experimental simulator was over two orders of magnitude faster than SPICE. >
A dual core oxide 8T SRAM cell with low Vccmin and dual voltage supplies in 45nm triple gate oxide and multi Vt CMOS for very high performance yet low leakage mobile SoC applications

In this work we have demonstrated, for the first time, a 0. 605µm2 dual core oxide (DCO) dual Vdd 8T SRAM cell in 45LPG triple gate oxide CMOS process for use as L1 cache for high performance low leakage mobile applications. The DCO 8T SRAM operates under dual voltage supplies with write assist. Compared to traditional single-end 8T cell, DCO 8T SRAM showed the same performance with only half the standby leakage, and lower Vccmin. The PU Vt and dual core oxide boundary were optimized to achieve robust Vccmin, process margin and reliability. The 45LPG thin core transistors and the DCO 8T SRAM are able to achieve 1.5GHz speed with ∼500mW at 0.9V and a low Vccmin of 0.6V.
Methodological triangulation: an approach to understanding data.

AIM To describe the use of methodological triangulation in a study of how people who had moved to retirement communities were adjusting. BACKGROUND Methodological triangulation involves using more than one kind of method to study a phenomenon. It has been found to be beneficial in providing confirmation of findings, more comprehensive data, increased validity and enhanced understanding of studied phenomena. While many researchers have used this well-established technique, there are few published examples of its use. DATA SOURCES The authors used methodological triangulation in their study of people who had moved to retirement communities in Ohio, US. REVIEW METHODS A blended qualitative and quantitative approach was used. DISCUSSION The collected qualitative data complemented and clarified the quantitative findings by helping to identify common themes. Qualitative data also helped in understanding interventions for promoting 'pulling' factors and for overcoming 'pushing' factors of participants. The authors used focused research questions to reflect the research's purpose and four evaluative criteria--'truth value', 'applicability', 'consistency' and 'neutrality'--to ensure rigour. CONCLUSION This paper provides an example of how methodological triangulation can be used in nursing research. It identifies challenges associated with methodological triangulation, recommends strategies for overcoming them, provides a rationale for using triangulation and explains how to maintain rigour. IMPLICATIONS FOR RESEARCH/PRACTICE Methodological triangulation can be used to enhance the analysis and the interpretation of findings. As data are drawn from multiple sources, it broadens the researcher's insight into the different issues underlying the phenomena being studied.
Improving dietary behaviour with nutrition labelling: Towards a research agenda that serves consumer well-being

We use multiple regression model and an unbalanced panel design for obtaining results and analyzing data. The results show that excess stock return is positively and significantly affected by turnover ratio, market to book ratio, return on assets, market return, and dividend yield. It is negatively and significantly affected by financial leverage, and gross domestic product
Female Land Ownership and Fertility in Nepal

Abstract This paper examines the association between female land ownership and fertility in Nepal using propensity score methods. A female land owner is found to have an average of 0.26–0.47 fewer children than her non-owner counterpart. Such negative female land-fertility trends are observed for women in different age groups. Evidence indicates that female land ownership promotes women’s wealth and decision-making authority, which could be the pathways through which their fertility is influenced. These findings imply that female land ownership could have substantial welfare benefits for women and population implications for countries.
The Efficacy of Intravitreal Vancomycin and Dexamethasone in the Treatment of Experimental Bacillus cereus Endophthalmitis

Purpose: Bacillus cereus causes the most virulent and refractory form of endophthalmitis. The authors analyzed effectiveness of intravitreal vancomycin with or without dexamethasone for experimental Bacillus cereus endophthalmitis. Methods: Rabbit eyes were injected intravitreally with 1 x 106 colony-forming units of Bacillus cereus organisms. At 24 hours after injection, eyes were injected intravitreally with 0.1 ml of balanced salt solution (group 1, n = 10), 1 mg vancomycin (group 2, n = 10), and antibiotic plus 0.4 mg dexamethasone (group 3, n = 10). Inflammatory scores were assessed 7 days and 14 days after treatment. Furthermore, histologic grading was carried out at the conclusion of the clinical observations. Results: Eyes treated with vancomycin, with or without dexamethasone at 7 days and 14 days expressed significant less inflammation over iris and vitreous than the control group (p < 0.05). Moreover, eyes treated with vancomycin with dexamethasone showed less inflammation over the conjunctiva and vitreous at 7 days and over the iris and vitreous at 14 days, compared to antibiotic treatment alone (p < 0.05). Additionally, at 14 days, the histopathological changes of eyes treated with vancomycin with dexamethasone had less conjunctival inflammation, mild iridocyclitis, less vitreous cells, and less choroidal vasculitis and retinitis compared to control group and antibiotic treatment alone, respectively (pp < 0.05). Conclusion: Intravitreal injection of vancomycin improved the therapeutic outcome of Bacillus cereus endophthalmitis. The addition of dexamethasone to antibiotic treatment provided a therapeutic benefit over antibiotic alone.

O-Linked β-N-Acetylglucosaminyltransferase Substrate Specificity Is Regulated by Myosin Phosphatase Targeting and Other Interacting Proteins*

O-GlcNAc-transferase (OGT) substrate specificity is regulated by transiently interacting proteins. To further examine the regulation of OGT, we have identified 27 putative OGT-interacting proteins through a yeast two-hybrid screen. Two of these proteins, Trak1 (OIP106) and O-GlcNAcase, have been shown previously to interact with and regulate OGT. We demonstrate here that MYPT1 and CARM1 also interact with and target OGT. MYPT1 and CARM1 are substrates of OGT in vitro and in vivo. MYPT1 and CARM1 also function to alter OGT substrate specificity in vitro. Furthermore depletion of MYPT1 in Neuro-2a neuroblastoma cells alters GlcNAcylation of several proteins under basal conditions, suggesting that MYPT1 regulates OGT substrate specificity in vivo.
The development and implementation of the structured training programme for caregivers of inpatients after stroke (TRACS) intervention: The London Stroke Carers Training Course

Objective: To describe the content and delivery of the adapted London Stroke Carers Training Course intervention evaluated in the Training Caregivers after Stroke (TRACS) trial. Setting: The London Stroke Carers Training Course is a structured training programme for caregivers of inpatients who are likely to return home after their stroke. The course was delivered by members of the multidisciplinary team while the patient was in the stroke unit with one recommended ‘follow through’ session after discharge home. Intervention: The intervention consists of 14 training components (six mandatory) that were identified as important knowledge/skills that caregivers would need to be able to care for the stroke patient after discharge home. Following national training days, the London Stroke Carers Training Course was disseminated to intervention sites by the cascade method of implementation. Results: The intervention was adapted for implementation across a range of stroke units. Training days were well attended (median 2.5 and 2.0 attendees per centre for the first and second days, respectively) and the feedback positive, demonstrating ‘face validity’ for the intervention. However cascading of this training to other members of the multidisciplinary team was not consistent, with 7/18 centres recording no cascade training. Conclusion: The adapted London Stroke Carers Training Course provided a training programme that could be delivered in a standardised, structured way in a variety of stroke unit settings throughout the UK. The intervention was well received by stroke unit staff, however, the cascade method of implementation was not as effective as we would have wished.
Comparing impulsiveness, hostility, and depression in borderline personality disorder and bipolar II disorder.

OBJECTIVE To determine whether borderline personality disorder (BPD) and bipolar II disorder can be differentiated from each other and from major depressive disorder (MDD) by comparing depression severity, impulsiveness, and hostility in mood disorder patients with and without BPD. METHOD One hundred seventy-three patients with either MDD or bipolar II disorder were enrolled from a larger sample admitted to a multisite project on mood disorders and suicidal behavior conducted from June 1996 through June 2006. Patients were divided into 4 groups: MDD with BPD, MDD without an Axis II diagnosis, bipolar II disorder with BPD, and bipolar II disorder without an Axis II diagnosis. All diagnoses were based on DSM-IV criteria. Depression was assessed using the 17-item Hamilton Rating Scale for Depression (HAM-D) and the self-rated Beck Depression Inventory (BDI). Impulsiveness was assessed using the Barratt Impulsiveness Scale, and hostility was assessed using the Buss-Durkee Hostility Inventory. RESULTS Patients with BPD reported higher levels of impulsiveness (p = .004) and hostility (p = .001), independent of Axis I diagnosis. Bipolar II patients reported greater attentional impulsiveness (p = .008) than MDD patients, independent of BPD status, while BPD patients reported greater nonplanning impulsiveness than patients without BPD, independent of Axis I diagnosis (p = .02). For motor impulsiveness, there was a main effect for Axis I diagnosis (p = .05) and Axis II diagnosis (p = .002). The bipolar II + BPD group scored the highest, suggesting a compound effect of comorbidity. There were no differences in depression severity when measured with the HAM-D, although the BPD groups reported more severe depression on the BDI, independent of their Axis I diagnosis (p = .05). The BPD groups scored higher on the cognitive factor (p = .01) and anxiety factor (p = .03) of the HAM-D. CONCLUSION Results suggest that there is a unique symptom and trait profile associated with BPD that distinguishes the diagnosis from bipolar II disorder. Results also suggest that impulsiveness is an important aspect of both disorders and that there is a compounding effect associated with a diagnosis of bipolar II disorder with comorbid BPD.
Traversing the Threshold in Child and Youth Care Education: A Qualitative Inquiry into the Meaning-Making Experience of Student Participants in an International Study Tour

This qualitative, relational-centred inquiry explores the learning experiences of a group of twenty Child and Youth Care (CYC) students who completed a twelve-day international study tour through parts of Ireland and Scotland. The international study tour offers experience-based learning opportunities for CYC students to see first-hand Irish and Scottish history, culture, and social care systems. Through this inquiry the student participants communicated and interpreted the meaning of their study tour experience. The data analysis revealed five thematic categories organized around five guiding research questions, the results of which are described below.
Change in body mass in relation to breeding phase in bull-headed shrikes

Changes in body mass of both sexes of the bull-headed shrike, Lanius bucephalus, were investigated over the six breeding phases of this species. Standardized body mass (SBM), which was defined as body mass divided by the length of the tarsus, of the males was relatively constant over the phrases, while the SBM of the females changed drastically. In the females, the SBM during egg-laying was higher than the SBM in all the other breeding phases. The SBM of the females did not differ between the incubation and early-nestling phases, and was lowest during the fledgling phase. Mass loss in bull-headed shrikes did not correspond to an adaptive adjustment of body mass to permit a reduction in the power required for flight in the nestling period. It is likely that incubating females constantly maintain their body mass to invest in parental efforts from the incubating to nestling periods.
Changing lifestyles in the age of fear: projective analysis of social insecurity and consumption patterns

This paper analyses the influence of social insecurity, consumer responses, and changes in consumption behaviour. The paper contributes to existing literature by including fear in consumer vulnerability domain. Due to the apparent research gaps in the field and scarce literature, as exploratory approach we chose a qualitative technique: an adaptation of the Zaltman Metaphor Elicitation Technique (ZMET) was used to gather metaphors for sensitive themes that are better expressed in terms of pictures and associative ideas. Under the basis of 64 projective interviews of victims or related to victims of social insecurity, their interpretations through symbolic imagination of the meaning of consumption in the face of public insecurity are identified. Results reveal that strong consumers' emotions are central to understand the consumption phenomena: fear, its sources, and its consequences in the form of changing lifestyles and purchase patterns are broad themes. Implications for managers, policy makers, and future research are offered.
A Subcubic Millimeter Wireless Implantable Intraocular Pressure Monitor Microsystem

We present a sub-mm<sup>3</sup>, fully wireless, implantable intraocular pressure monitor microsystem (IMM) that comprises a powering coil, an antenna, a piezoresistive micro-electro-mechanical system pressure sensor, and a pressure sensing IC. The system provides a 24-h intraocular pressure monitoring, which is not possible with currently used tonometric measurements. The IMM volume is limited to 0.38 mm<sup>3</sup> (4 × smaller than previous state-of-the-art) for the studies on laboratory rodents prior to human use. A cavity resonator magnetic coupling delivers the wireless power to the chip with 4.89% efficiency. The chip senses a change in a differential sensor resistance by providing a low-power differential resistance to frequency conversion with the measured standard deviation in differential resistance sensing of <inline-formula><tex-math notation="LaTeX"> $\text{133}\ {\rm{m}}\Omega $</tex-math></inline-formula>. The data packets are wirelessly transmitted by an ultralow power 2.4-GHz ISM band OOK transmitter. The IMM is integrated on a 5-<italic>μ</italic>m-thick biocompatible Parylene C substrate. Implemented in a 0.18-μm CMOS process, the system achieves 0.67-mmHg pressure sensitivity with differential resistance sensing and dissipates only 6.3 nW with 30 min of measurement intervals. We verify the IMM functionality in the <italic>in vivo</italic> biological experiment.
Stability and Sensitivity Analysis of Uniformly Sampled DC-DC Converter With Circuit Parasitics

In this paper the stability and sensitivity function of three basic dc-dc converter with the consideration of circuit parasitics has been analyzed for analog and digital controller implementation. The steady state and small-signal analysis has been used to derive the mathematical expressions for uniformly sampled voltage-mode controlled converters. The effect of digital controller using the ratio of sampling to carrier frequency has been analyzed. The sampling frequency limits the voltage gain in the stepped manner and also affects the stability of the digitally controlled converter. The sensitivity function has been defined for voltage gain with respect to various system parameters. The maximum affected regions on duty ratio scale with corresponding parasitic variable have been discussed. The detailed stability analysis has been carried out for digitally implemented three basic dc-dc converters, i.e., buck, boost, and buck-boost circuits. The analytical results are verified with the simulations performed in PSCAD/EMTDC. An FPGA controller is considered as digital controller for the dc-dc converter and verification of the results through experiment.
