Global Finish Curvature Matched Machining

Wang, Jianguo 18 November 2005 (has links) (PDF)
As competition grows among manufacturing companies, greater emphasis has recently been placed on product aesthetics and decreasing the product development time. This is promoting and standardizing widespread use of sculptured surface styling within product design. Therefore, industries are looking for high efficiency machining strategies for sculptured surface machining (SSM). Many researchers have produced various methods in tool path generation for SSM. Five-axis curvature matched machining (CM2) is the most efficient. With the widespread use of 5-axis mill in industries, CM2 is a better solution for improving the machining efficiency for product concept models. CM2 has very good performance for global machining of single patch surface or a quilt of simple sculptured surface patches. But when CM2 is used to generate tool paths for global machining of a large region of complex sculptured surface such as the top or side skins of a vehicle, there will be some limitations, that is, the performance will be influenced greatly in some steep areas where the lead angle of the tool becomes larger to match the curvature or avoid gouging. Larger lead angles mean smaller effective curvatures at the leading edge of the tool bottom where it contacts the part surfaces. Therefore, the density of CM2 tool path is very high in these steep regions. By setting a smaller upper limit for the lead angle, the density of tool path will not be very high in the steep regions, but there will be some uncut materials. This thesis focuses on how to determine the uncut or rework areas of the previous CM2 and how to define the boundary of these regions. Strategies for generating more efficiency CM2 tool paths are also discussed. These methods will be tested by applying finish global machining to a one-fourth scale Ford GT model.

A Content Analysis of Inquiry in Third Grade Science Textbooks

Lewis, Rebecca Adams 17 April 2012 (has links) (PDF)
Since the publication of the National Science Education Standards in 1996 efforts have been made to include inquiry into school science programs. An addendum on inquiry to these standards was published in 2000 presenting five essential features of classroom inquiry as indicators of the active use of inquiry in a science lesson. The purpose of this content analysis was to examine and identify the presence of these five essential features of classroom inquiry within publisher-identified inquiry activities found in the 2000 and 2010 teacher's editions of the third grade science textbooks published by Scott Foresman. The textbooks were read and coded using each of the five essential features of classroom inquiry as a priori categories. Data from both textbook editions indicated that although these activities were identified as inquiries, only a few contained all five essential features, while about half contained none. Approximately half of the publisher-identified inquiries were partial inquiries, containing less than five of the essential features. Teachers who use these resources should be aware of the presence or lack of the essential features in order to supplement the science curriculum. Publishers need to be more explicit in including these features and further research should be conducted in more textbooks to better understand the quality and quantity of inquiry activities found within these resources.

Diarrhea and its Determinants in Under-five Children in Chad Republic

Aderinwale, Oluseyi, Adenusi, Adedeji, Olagunju, Olajide, Asifat, Olamide, white, Melissa, Quinn, Megan 25 April 2023 (has links)
Background: Diarrhea is the passage of 3 or more loose or liquid stools per day. Globally, it is the second-leading cause of death among under-five children, accounting for 9% of all under-five deaths, and kills more young children than Acquired Immunodeficiency Syndrome (AIDS), malaria and measles combined. In developing countries, an estimated 1.8 million people die annually due to diarrheal diseases, and more than 80% of them are children under 5 years, while 88% of these deaths are in South Asia and Sub-Saharan Africa (SSA). There are limited studies that investigate the prevalence and factors associated with diarrhea in SSA despite the health burden. Method: The Demographic and Health Survey (DHS) children’s recode dataset of 2015 for Chad was used for this study. The predictor variables were; age of child, source of drinking water, maternal highest level of education, drank from bottle with nipple, and the outcome variable was diarrhea recently. Descriptive statistics for all variables were completed, and Chi-square analyses were conducted to determine associations between predictor variables and the outcome, diarrhea recently. Simple and multiple logistic regressions were completed to determine factors that predict diarrhea in the last two weeks. Odds ratios, 95% confidence intervals, and p-values were reported. Results: The total sample size was (N=16,710). About 3292 (19.70%) children had diarrhea, 13418 (80.30%) children had no diarrhea. A high prevalence of diarrhea in under-five children was observe particularly in those who drink water from unprotected well (1070 cases), had mothers with only primary level of education (796 cases), and did not drink from bottles with nipple (2961 cases). Based on the age of child, the odds of having diarrhea were over 60% lower in children 3 years old and below [aOR = 0.39, C.I (0.279-0.538), p <.0001] compared to 4 years old and above. Based on the source of drinking water, children that drank from a protected spring were 74% less likely to have diarrhea [0.26, 0.084-0.827, p=0.0223] compared to those that drank from other sources. The study also showed that children that drank from bottles with nipple were 16% less likely of having diarrhea [0.84, 0.726-0.968, p=0.0166] compared to those that did not drink from bottles with nipple. However, maternal highest level of education had no significant association with the odds of having diarrhea in these children. Conclusion: Caregivers should ensure absolute hygiene and provide safe drinking water to under-five children, especially those above 3 years who may easily access contaminated water sources themselves. We also encourage the use of bottles with nipple heads for drinking in children. Further studies are needed in SSA on other factors influencing diarrhea risk in those under five.

Does Work Context Matter? Understanding the Role of Work Context on the Relation between Personality and Job Satisfaction

Meaghan Marie Tracy (15353512) 29 April 2023 (has links)
<p>As more organizations adopt varying work arrangements (e.g., remote, in-person work), it is increasingly important to understand factors that associate with employee’s job satisfaction under different work contexts. Previous studies, based almost entirely on in-person work contexts, have mixed findings on whether certain personality traits relate to job satisfaction. The current meta-analysis investigates the potential moderating role of work context on the relation between personality and job satisfaction. Specifically, I examine how personality traits are associated with job satisfaction differently under remote and in-person work contexts. I first compiled an integrated definition of remote work and identified the unique characteristics that contrast remote from in-person work contexts. Drawing from interactionist theories, I then highlighted how the characteristics of work context could moderate the relation between the Big Five personality traits and job satisfaction. I conducted a meta-analysis, quantitatively summarizing findings from 246 studies (<em>N</em> = 260,492). Results suggested that all five Big Five personality traits are significantly related to job satisfaction, however work context did not moderate the relation. Overall, findings from the current study suggest that the personality-job satisfaction relation is statistically significant and robust across contextual differences.</p>

Investigation of level and differentials in child mortality in South Africa: insight from Census 2001 and 2011, Community Survey 2016 and Demographic and Health Survey 2016

Matikinca, Ntombizandile 29 March 2023 (has links) (PDF)
Measuring levels of childhood mortality is important for low and middle-income countries to monitor overall development and progress towards improved child health. The overall aim of this research is to estimate the level and trend of childhood mortality in South Africa over time, and to examine the factors associated with and the determinants of childhood mortality. The study discovered that significant progress has been made to reduce the levels of childhood mortality in the country. The estimates derived through direct estimation using the 2016 South African Demographic and Health Survey (SADHS) for the period between 2012-2016 revealed age-specific mortality rates were: Neonatal Mortality Rate (NMR) was 22.0 per 1 000 live births, Post-neonatal Mortality Rate (PNMR) 13.1, 1q0 34.9, 1q4 5.5 and 5q0 40.2 per 1 000 live births. Investigation of the factors associated with childhood mortality revealed significant differentials in age group, sex, population group, province, socio-economic status and household characteristics. Overall, children aged less than one month and those aged between one to two months had a higher mortality risk than the other age groups; male children had an increased risk of dying than females; Black and Coloured children had an increased risk of dying compared to children in other population groups; children in Mpumalanga, Eastern Cape and North West had a higher risk of dying compared to children in other provinces; children whose mothers had below secondary education had higher risks of mortality; and children with poor water source and toilet facility were more likely to die than other children with better facilities. The results were generally in agreement with the existing literature. Although the study found significant improvement in the level of childhood mortality over the period 1996-2016, further progress is achievable as many children still continue to die of preventable or treatable causes. The findings of this study may assist government, policymakers and researchers to plan, and implement targeted interventions that will further reduce the levels of childhood mortality in South Africa.

An experimental and numerical study of secondary flows and film cooling effectiveness in a transonic cascade

Kullberg, James C. 01 May 2011 (has links)
Experimental tests on a transonic annular rig are time-consuming and expensive, so it is desirable to use experimental results to validate a computational model which can then be used to extract much more information. The purpose of this work is to create a numerical model that can be used to simulate many different scenarios and then to apply these results to experimental data.; In the modern world, gas turbines are widely used in aircraft propulsion and electricity generation. These applications represent a massive use of energy worldwide, so even a very small increase in efficiency would have a significant beneficial economic and environmental impact. There are many ways to optimize the operation of a gas turbine, but a fundamental approach is to increase the turbine inlet temperature to increase the basic thermodynamic efficiency of the turbine. However, these temperatures are already well above the melting temperature of the components. A primary cooling methodology, called film cooling, creates a blanket of cool air over the surface and is an effective way to help protect these components from the hot mainstream gasses. This paper focuses on the effect of the film holes upstream of the first row of blades in the turbine because this is the section that experiences the highest thermal stresses. Many factors can determine the effectiveness of the film cooling, so a complete understanding can lead to effective results with the minimum flow rate of coolant air. Many studies have been published on the subject of film cooling, but because of the difficulty and expense of simulating turbine realistic conditions, many authors introduce vast simplifications such as low speed conditions or linear cascades. These simplifications do not adequately represent the behavior of a turbine and therefore their results are of limited use. This study attempts to eliminate many of those simplifications. The test rig used in this research is based on the NASA-GE E³ design, which stands for Energy Efficient Engine. It was introduced into the public domain to provide an advanced platform from which open-literature research could be performed.

Who is the best judge of personality: Investigating the role of relationship depth and observational breadth on the accuracy of third-party ratings

Tindall, Mitchell 01 January 2015 (has links)
To date, the vast majority of research regarding personality in IO Psychology has relied on self-report assessments. Despite support for the utility of third-party assessments, IO Psychologists have only just begun extensive research in this area. Connelly and Ones (2010) conducted a meta-analysis that demonstrated that accuracy of third-party ratings improved as intimacy between the judge and the target grew. This remained true with the exception of predicting behavioral criteria, where non-intimates maintained superior predictability (Connelly & Ones, 2010). This was later contradicted by a recent investigation that found the best predictive validity for third-party assessments when they are taken from personal acquaintances as opposed to work colleagues (Connelly & Hulsheger, 2012). The current study is intended to investigate how the depth of the relationship and breadth of behavioral observations differentially moderate the relationship between third-party personality assessments and accuracy criteria (i.e., self-other overlap, discriminant validity and behavior). Results indicate that both depth and breadth impact accuracy criteria and they do so differentially based on trait visibility and evaluativeness. These findings will be discussed along with practical implications and limitations of the following research.

Personality Inventory DSM-5: A Spanish Translation for Hispanics in the United States

Carmona, Jessica Abigail 01 July 2019 (has links)
The Personality Inventory DSM-5 (PID-5) was created to measure personality pathology and help in the development of a dimensional conceptualization of personality disorders (Krueger, Derringer, Markon, Watson, & Skodol, 2012). It measures five maladaptive personality traits: Negative Affect, Detachment, Antagonism, Disinhibition and Psychoticism. The PID-5 has also garnered significant support for its hierarchical structure, five-factor structure across samples and translations, and its ability to predict variance in internalizing and externalizing disorders (Krueger & Markon, 2014). The current study builds on this literature by translating the PID-5 into Spanish spoken in Latin America and testing the replicability of the five-factor structure, reliability, and validity of the PID-5-Sp facets in a Hispanic sample. Using Mechanical Turk, 305 participants completed the PID-5-Spanish, Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder (GAD7), Aggression Questionnaire-Revised (AQ-R) and the Big Five Inventory (BFI). EFA suggested a three-factor structure that resulted in two small factors that were conceptually similar to Antagonism and Detachment and one large global general distress factor. CFA results indicated that a five-factor solution had a poor fit for the current sample. Reliability was acceptable for most facets (α = .60-.95, M= .85). In general, PID-5-Sp domains showed moderate to strong correlations with theoretically congruent normative traits, with exception of Psychoticism, which was not significantly correlated with Openness to Experience (r = -.08, p = > .05). As expected, Detachment and Negative Affect predicted GAD-7 and PHQ-9 scores. Aggression scores were predicted by Negative Affect, Antagonism and Disinhibition. Overall, the PID-5-Sp partially replicated previous validity and reliability findings. However, future research is needed to further test the five-factor structure and its replicability in non-Western samples.

THE PERFORMANCE OF ESG THEMATIC FUND IN CHINA AND ESG RATINGS

Zhao, Zhimei, 0000-0003-2973-6647 January 2022 (has links)
We uses ESG thematic funds to conduct a detailed statistical profile of their operating status in the Chinese market, including the size, the proportion of different investment types, and the characteristics of return and risk. The OLS model is used to empirically analyze the applicability of the Fama-French five-factor model in the Chinese mutual fund market. Based on the a ESG rating as a starting point, we study the profit improvement mechanism and risk-return characteristics of the ESG portfolios. The main findings are that the five-factor model better explained the excess returns of ESG thematic funds during the entire sample period of the study and can be used for attribution analysis of the performance. It shows that, despite the poor performance of ESG thematic funds in the market during certain periods, there is no significant difference between the performance of ESG thematic funds and the market during the economic crisis. The ROEs and dividend rates of the ESG high-scoring groups are both higher than those of the ESG low-scoring groups. This shows that companies with higher ESG scores have higher and more sustainable profitability and greater willingness to pay dividends. Furthermore, the ESG high-scoring group has better returns and lower risks. / Business Administration/Finance
