Prevalence of obesity in a paediatric outpatient clinic

This study assessed the rate of overweight and obese children at a general paediatric outpatient clinic, Mater Dei Hospital, Malta, in 2011. This was an observational, prospective study where 220 patients aged 2-14 years attending this clinic, with a preponderance of asthmatic children, had their height and weight measured and their BMI calculated. Overall, 40.5% of the children were either overweight (14.1%) or obese (26.4%). There were more obese boys (31.8%) than girls (18.2%) (p=0.025). Half of the asthmatic patients were overweight or obese (49.6%), compared to a quarter of the non-asthmatic patients (27.5%) (p=0.001). The high rate of obesity in this setting presents an opportunity and challenge for paediatricians to address the most important nutritional problem in children.peer-reviewe

Text Analytic System: Document Similarity

Knowledge discovery is a critical function of infrastructure protection in the U.S. By analyzing key text documents, we can gain insight into the interwoven and interdependent infrastructure system of the U.S., and better understand the security aspects of the system as a whole. Massive amounts of relevant data resides in text documents, which must be gathered and parsed to be analyzed on a large scale. Our algorithm collects web-based text embedded in HTML pages and analyzes it in various ways to decipher similarities. It will be a needed component of the larger system being developed by the Idaho National Laboratory, which will seek to accomplish what was described above. By analyzing the similarity of these HTML documents, we are helping the Idaho National Laboratory to keep redundant data out of the database. Without proper parsing of similar data, repetitive entries may clog the system with unneeded information. We attack this problem by providing a series of interfaces, each culminating into the same comparison algorithm. The interface can accept a raw String, a text file, or a web URL. The BoilerPipe library is used to extract useful text from the HTML document, by stripping the document of its tags, and using a series of filters to acquire desired text. A simple Java scanner is used to parse the text file. This text is then lemmatized, stripped of punctuation, converted to lowercase, stemmed, and put into a term-document matrix. Finally, we use cosine similarity to generate a proper percentage point representing how similar or dissimilar the two provided text documents are.https://scholarscompass.vcu.edu/capstone/1025/thumbnail.jp

Enhancement of thrust reverser cascade performance using aerodynamic and structural integration

This paper focuses on the design of a cascade within a cold stream thrust reverser during the early, conceptual stage of the product development process. A reliable procedure is developed for the exchange of geometric and load data between a two dimensional aerodynamic model and a three dimensional structural model. Aerodynamic and structural simulations are carried out using realistic operating conditions, for three different design configurations with a view to minimising weight for equivalent or improved aerodynamic and structural performance. For normal operational conditions the simulations show that total reverse thrust is unaffected when the performance of the deformed vanes is compared to the un-deformed case. This shows that for the conditions tested, the minimal deformation of the cascade vanes has no significant affect on aerodynamic efficiency and that there is scope for reducing the weight of the cascade. The pressure distribution through a two dimensional thrust reverser section is determined for two additional cascade vane configurations and it is shown that with a small decrease in total reverse thrust, it is possible to reduce weight and eliminate supersonic flow regimes through the nacelle section. By increasing vane sections in high pressure areas and decreasing sections in low pressure areas the structural performance of the cascade vanes in the weight reduced designs, is improved with significantly reduced levels of vane displacement and stress
