Unrestrained Cylinders Rolling in Steady Uniform Flows

Abstract : Ordnance remediation projects for underwater sites have suggested that understanding the motion of cylinders (the approximate shape of ordnance) in flows would help to predict regions of ordnance mobility, prioritize remediation efforts, and improve the design of engineering works trap ordnance. Therefore, to develop a better understanding of the motion of cylinders, the characteristics of motion of smooth, unrestrained cylinders in contact with a smooth horizontal bed were investigated in a flume with steady, uniform flows. Inviscid flow theory was used to estimate maximum cylinder velocities and numerical simulations were used to understand the hydrodynamic forces on the cylinders. Eight cylinders were used in the laboratory experiments having varying specific gravities and diameters. At low velocities, experiments showed that the cylinders follow trends similar to those noted in sediment particle studies. Incipient motion velocities were highest for the heavier cylinders. At high flows, the terminal velocity of the cylinders was limited to between 60-80 percent of the free stream flow. The cylinders accelerated to their maximum velocities within about one second. Inviscid-flow theory derivations implied that the maximum velocity of the cylinder would be 71 percent of the free stream flow which was consistent with the experiments. Use of potential flow theory was assumed valid (as an estimator) because experiments verified that flow over the rolling cylinder did not separate from the cylinder surface and that they were reasonably two-dimensional. The numerical results showed that separation from the cylinder would be eliminated by the moving surface of the cylinder. In fact, suppression of separation occurred even when the cylinder was rolling at only 60 percent of the free-stream flow velocity.
Capabilities meet regulation : the compliance processes of Mexican food supply chains with United States biosecurity regulations

This thesis explores how Mexican fresh produce supply chains have responded to US bio-security regulations designed to prevent the intentional and accidental contamination of imported food. It explores the compliance processes, which are theorised using a framework drawn from the Resource-Based View (RBV) and the Supply Chain Governance (SCG) literatures. The constructs developed herein regarding capabilities and supply chain ‘governance structures’ complement previous Regulation Studies (RS) explaining compliance behaviour. The thesis analysed 12 case studies, and tested causal conditions of compliance using a multi-value Qualitative Comparative Analysis (mvQCA) method. The main results show: 1) the pathways to meet the regulatory requirements; 2) the limited diversity of capabilities associated with higher levels of compliance; and 3) the importance of tight supply chain coordination to source and exchange knowledge for compliance, regardless of how or who governs the supply chain. The thesis contributes to various academic debates. It removes the RVB assumptions that resources and capabilities are intrinsically valuable and complementary, and therefore contributes towards making the theory less tautological. It shows how SCG benefits when the effects of supply chain integration and coordination are examined independently. It differentiates between firms lacking willingness and firms lacking capabilities to comply, making it possible to define suitable regulatory strategies for each type of firm. The thesis makes a methodological contribution as it is one of the first studies applying the mvQCA in Science, Technology and Innovations Studies (STIs). The new methodology is used here to test the causal conditions of compliance, but can also be applied to innovative performance more generally. The thesis concludes by showing how US regulations were effective in achieving their regulatory aims without significant negative consequences, and suggesting that STI regulatory policies can be used to increase business engagement to prevent the intentional and accidental contamination of the food chain.
Topic Predictions and Optimized Recommendation Mechanism Based on Integrated Topic Modeling and Deep Neural Networks in Crowdfunding Platforms

The accelerated growth rate of internet users and its applications, primarily e-business, has accustomed people to write their comments and reviews about the product they received. These reviews are remarkably competent to shape customers’ decisions. However, in crowdfunding, where investors finance innovative ideas in exchange for some rewards or products, the comments of investors are often ignored. These comments can play a markedly significant role in helping crowdfunding platforms to battle against the bitter challenge of fraudulent activities. We take advantage of the language modeling techniques and aim to merge them with neural networks to identify some hidden discussion patterns in the comments. Our objective is to design a language modeling based neural network architecture, where Recurrent Neural Networks (RNN) Long Short-Term Memory (LSTM) is used to predict discussion trends, i.e., either towards scam or non-scam. LSTM layers are fed with latent topic distribution learned from the pre-trained Latent Dirichlet Allocation (LDA) model. In order to optimize the recommendations, we used Particle Swarm Optimization (PSO) as a baseline algorithm. This module helps investors find secure projects to invest in (with the highest chances of delivery) within their preferred categories. We used prediction accuracy, an optimal number of identified topics, and the number of epochs, as metrics of performance evaluation for the proposed approach. We compared our results with simple Neural Networks (NNs) and NN-LDA based on these performance metrics. The strengths of both integrated models suggest that the proposed model can play a substantial role in a better understanding of crowdfunding comments.
Awareness towards Accountancy as a Profession

This study investigates the awareness of secondary school students towards accountancy as a profession due to the shortage of qualified accountants required by Malaysia government in the era 2020. A lack of information/misinformation about what accounting is and what accountants do which caused the school leavers having less awareness regarding the accountancy profession. There are four factors that been tested; namely as gender, personal interest, level of difficulties for accounting subject as well as knowledge and career prospects. The study focuses on secondary school students and 270 students who taking Principle of Account subject at Segamat, Johor and Muadzam Shah, Pahang secondary. The analysis of data utilizes the statistical package of SPSS. The result revealed that personal interests as well as knowledge and career prospects have significant relationship with the awareness of students towards accountancy as a profession. Meanwhile gender and level of difficulties for accounting subject do not have significance difference/relationship with the awareness of students towards accountancy as a profession.
A New Dimensionless Approach to Assess Relative Permeability Modifiers

Water production is one of the common problems that is faced in mature gas reservoirs. A number of methods exist to tackle this problem, including injecting polymer that can selectively reduce water production. There are many factors that affect this treatment, such as rock permeability and porosity, flowing fluid phases, polymer concentration, and the dependency of polymer thickness on the flow rate of each phase. In this manuscript, we propose a dimensionless form of the effective pore radius (reff–) that can be used to evaluate the effectiveness of such a treatment. This form takes into account the thickness of the absorbed polymer layer onto the pore surfaces of the rock, which is an important factor controlling the performance of the treatment. Our newly developed reff– explicitly demonstrates the effects of the above factors by considering them during its calculation. This manuscript also demonstrates the application of reff– in analyzing the outcome of a number of experiments conducted in this work.
Can we perform adjuvant chemotherapy alone in stage IB/IIA cervical cancer meeting Sedlis criteria?

Background: The aim of this study was to evaluate the effectiveness of chemotherapy alone as postsurgical adjuvant therapy on survival of patients in stage IB/IIA cervical squamous cell carcinoma meeting Sedlis criteria. Methods: We retrospectively reviewed the records of 127 patients satisfying Sedlis criteria after radical surgery for stage IB/IIA cervical cancer from January 2009 to December 2013. Of these, 65 patients received radiotherapy (RT)/chemoradiotherapy (CRT), 62 patients received chemotherapy (CT) alone. Both the treatment modalities were compared on 5-year overall survival (OS), disease-specific survival (DSS), recurrence rates and side effects. Results: Median follow-up time for surviving patients was 75 months. The 5-year OS was similar in both the groups with 85.5% in the CT and 87.7% in the RT/CRT group, respectively, (p=0.727). Likewise, there was no significant difference in 5-year DSS between the two arms (CT: 87.1% vs. RT/CRT: 90.8%; P=0.548). Rate and the pattern of recurrence were not different between the groups. Acute toxicity was more frequent in the CT group, but was statistically insignificant (P>0.05). The incidences of urinary disturbance (P=0.003) and lymphedema (P=0.041) were fewer in the CT group. Conclusions: Adjuvant CT alone for early-stage cervical cancer patients who meet the Sedlis criteria might be a good alternative to RT/CRT.
MONITORING THYROID HORMONES, SOME OF OXIDATIVE STRESS MARKERS AND BIOCHEMICAL CHANGES DURING THE EARLY AND MID STAGE OF LACTATION IN DAIRY COWS

This study aimed to compare changes in biomarkers of nutrient metabolism, thyroid hormones and oxidative stress parameters present during the early (EL) and mid-lactation (ML) stages in dairy cows reared under the hot summer conditions at Assiut city, Upper Egypt. Blood serum of twenty nine multiparous clinically healthy lactating Holstein Fresien cows (16 early lactating and 13 mid lactating cows) belonged to a private farm located under the same temperatures and living conditions were used in this study. Cows of ML had significantly lower values (P < 0.05) than those of EL stage for glucose and cholesterol concentrations and also non-significantly differences in total protein, albumin and triglycerides (P>0.05). Similarly, non-significance differences (P> 0.05) were found between the two lactation stages for thyroid hormones (Triiodothyronine, Thyroxine). For oxidants/antioxidant parameters, ML cows had significantly decreased values (P<0.05) for Superoxide dismutase and significantly increased values (P<0.05) for Glutathione S-Transfereas activities than those of EL as well as non-significantly differences (P>0.05) for Malondialdehyde concentrations and catalase activity. Pearson’s correlation coefficients between the metabolic parameters, thyroid hormones and oxidative indices in early and mid-stages of lactation showed different positive and also negative correlations. Can be concluded that this study gives evidence that the lactating cows undergo a substantial oxidative stress that related to metabolic and physiological adaptation during early lactation to mid lactation stages under the under the influence of high temperature conditions at Upper Egypt.
Development of teat sensing system for automated milking

Robotic application of milking cups to the udder of a cow in a rotary high capacity group milking system is a major challenge in automated milking. Application time and reliability are the main constraints. Manual application by an operator of a rotary carousel is of the order of 10 seconds and 100% reliable. In existing non-rotary milking machines, the cups are applied to each teat individually and the process can take up to two minutes. In order to achieve a more rapid simultaneous application of the four cups, the three dimensional locations of the four teats must be known in real time. In this thesis, a multimodal vision system combining optical stereovision and thermal imaging is developed. The overall system is evaluated from the point of view of accuracy and robustness. Laboratory tests have shown that stereovision can rapidly locate teat three dimensional position coordinates, however robust identification of the teats is required. It is shown that this may be achieved using thermal imaging to isolate teats from background objects due to their elevated temperature profile. Further development is necessary to overcome specific situations such as overlapping teats.
The interlanguage Speech Intelligibility Benefit for Korean Learners of English: Production of English Front Vowels

The present work is a follow-up study to that of Han, Choi, Lim and Lee (2011), where an asymmetry in the source segments eliciting the interlanguage speech intelligibility benefit (ISIB) was found such that the vowels which did not match any vowel of the Korean language were likely to elicit more ISIB than matched vowels. In order to identify the source of the stronger ISIB in non-matched vowels, acoustic analyses of the stimuli were performed. Two pairs of English front vowels [i] vs. [I], and vs. were recorded by English native talkers and two groups of Korean learners according to their English proficiency, and then their vowel duration and the frequencies of the first two formants (F1, F2) were measured. The results demonstrated that the non-matched vowels such as [I], and produced by Korean talkers seemed to show more deviated acoustic characteristics from those of the natives, with longer duration and with closer formant values to the matched vowels, [i] and , than those of the English natives. Combining the results of acoustic measurements in the present study and those of word identification in Han et al. (2011), we suggest that relatively better performance in word identification by Korean talkers/listeners than the native English talkers/listeners is associated with the shared interlanguage of Korean talkers and listeners.
Factors associated with double and triple burden of malnutrition among mothers and children in Nepal: evidence from 2016 Nepal demographic and health survey

Background Double and triple burden of malnutrition is defined by the coexistence of overweight/obese mother and undernourished child and coexistence of overweight/obese mother and undernourished and anemic child at the same household level respectively. The aims of this study were to explore the coexistence of overweight/obesity among mothers and undernourished and anemia among children and associated factors among the mother-child pairs in the same household. Methods A total sample of 5018 mother-child pairs from the Nepal Demographic and Health Survey (NDHS) 2016 were included in the study. Anthropometric measurements, hemoglobin level of the children and their mothers were taken. The bivariate and multivariate logistic regression were performed to observe the factors associated with the double and triple burden of malnutrition. To assess the outcome, we created the categories such as the double and triple burden of malnutrition where the overweight/obese mother and undernourished (stunted or wasted or underweight) child and overweight/obese mother and undernourished (stunted or wasted or underweight) child and anemic child respectively. Results Prevalence of double burden of malnutrition (DBM) and triple burden of malnutrition (TBM) was 6.59(5.13-8.84)% and 7(5.42-8.99)% respectively at the same household. In the adjusted multivariate logistic regression, mothers with short stature (AOR=3.94, 95% CI: 1.94-8.00), from the richest wealth status (AOR=2.59, 95% CI= 1.27-5.28), age groups of 26-49 years (AOR=2.38, 95% CI: 1.18-4.77), attended at least a secondary level of education (AOR=1.93, 95% CI: 1.01-3.69) were more likely to have the double burden of malnutrition. Similarly, mothers who had short stature (AOR=4.48, 95% CI: 2.19-9.16), the richest wealth status (AOR=2.46, 95% CI= 1.19-5.08) and age groups of 26-49 years (AOR=2.27, 95% CI: 1.16-4.44) were more likely to suffer from the triple burden of malnutrition. Conclusions Our study concludes with the prevalence of double and triple burden of malnutrition existence among mothers and children in Nepal. Mothers having short stature and from the richest family are more prone to double and triple burden of malnutrition. Integration of maternal health promotion and nutrition education program would be a good strategy to prevent mother overweight/obesity and stunting among children under five years of age in Nepal.
Evaluation of the BLWF Code - A Tool for the Aerodynamic Analysis of Transonic Transport Aircraft COnfigurations

The BLWF code [1] was developed by researchers at the Central Aerohydrodynamic Institute (TsAGI). The BLWF code has been developed for preliminary aerodynamic analysis of transonic transport aircraft configurations. It can be used for rapid computations of viscous transonic flow over wing/body/nacelle/ tail configurations. Numerical simulations of the flow past the DLR-F6 wing-body configuration have been performed to evaluate the accuracy and efficiency of this code, when used for preliminary aerodynamic analysis of transonic transport configurations. A brief description of computational methods is given in Section 1. The numerical results and discussion are given in Section 2. The computational results for a prescribed Mach number (Ma=0.75) and prescribed design lift coefficient (CL=0.5) are compared with the available experimental data. The effect of Mach number on the aerodynamic performance is investigated by computations at Mach numbers from 0.2 to 0.9, with fixed Reynolds number and varying angles of attack. According to the evalution results, the BLWF code is well suited for the preliminary aerodynamic analysis of transonic transport aircraft configurations.
Use of multimedia services within ubiquitous environments : the role of place in the usage process of mobile data services

Recently, there have been rapid developments in the fields of mobile and wireless technologies which have enabled the acquisition of information at anytime regardless of the location and mobility status of the users. However, despite the increasing popularity of mobile devices which are becoming an indispensable part of our everyday activities, the disappointing results regarding the adoption and use of mobile applications and data services lead scholars to question the understanding of the adoption and usage behaviour within these new wireless environments. The author believes that there could be attributes which are still unexplored and could provide an explanation why the mobile data services are still unsuccessful. The aim of this study is to explore, understand and highlight the role of place in the decision of the people to use mobile data services and thus to assist professionals and scholars to consider the importance of the attributes of place in the design of new applications and in the adoption and usage models of mobile technologies and services. In order to achieve this objective an exploratory in nature research was conducted combining conventional and innovative research methodologies. A model of place was generated which served as a sensitizing device in order to interpret, and analyse the collected data. The first phase of this research involved the understanding of the market in question and the selection of the appropriate case (mobile data services platform) to conduct the research. The second main phase of the research then sought to get a better understanding of how users experience place before deciding to use mobile data services. The research methods were applied within everyday settings with 30 users of the selected mobile data services platform, all of whom were selected according to specific criteria. The findings tend to suggest that participants did experience the different places in a similar way before deciding to use mobile data services.
Comparison of MSP and Non-MSP Schools in Six States.

This pilot study proposes a set of analytical steps for comparing schools that participate in the National Science Foundation’s Math and Science Partnership (MSP) Program and their intrastate non-participating peers. This pilot is part of a larger effort to evaluate the MSP Program’s role in student achievement, along with two companion analyses. While our pilot study uses a comparative approach, the paper by Dimiter Dimitrov (this volume) follows a within-group design. The third analysis by Robert K. Yin (this volume) covers the varied designs used by the MSPs themselves in their own evaluations. As this pilot study has progressed, there has emerged three distinct phases of analysis. Phase I focused on the participating schools within four Math and Science Partnerships (MSPs) located in three states. Phase II expanded Phase I to focus on three more MSPs in three additional states. The Phase III study was conducted using six cohort I MSPs in four states, and will eventually include the nine cohort I MSPs in all six states from Phase I and Phase II. For each phase, the MSP participating schools were carefully matched with the non-participating schools on eight demographic variables to form a comparison group. This paper offers detailed documentation on how we operationalize matching methods for comparative purposes. We conclude that carefully executed matching methods are promising for large-scale comparative analysis on the effects of the MSP Program across all involved states. The study draws on publicly accessible school-level standardized test data from six states and from data available at the National Center for Education Statistics’ Common Core of Data (NCES CCD). In addition, the study uses documents available via MSPnet, and Web site information reported by the individual MSPs in the MSP Program accessible through the school year 2005-06.
