Underwater robots are expected to be used for various work assignments. The large variety of applications of underwater robots motivates researchers to develop control systems and technologies for underwater robots. Several control methods have been proposed so far for the stabilization of nominal system model of underwater robots with no parameter uncertainty. Parameter uncertainties are considered to be obstacles in implementation of the such nominal control methods for underwater robots. The objective of this study is to establish a robust stabilization method for rotational motion of underwater robots against parameter uncertainties. The effectiveness of the proposed method is verified by numerical simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robust%20control" title="robust control">robust control</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization%20method" title=" stabilization method"> stabilization method</a>, <a href="https://publications.waset.org/abstracts/search?q=underwater%20robot" title=" underwater robot"> underwater robot</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20uncertainty" title=" parameter uncertainty"> parameter uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/119269/robust-stabilization-of-rotational-motion-of-underwater-robots-against-parameter-uncertainties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119269.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Variation of Phenolic Compounds in Latvian Apple Juices and Their Suitability for Cider Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rita%20Riekstina-Dolge">Rita Riekstina-Dolge</a>, <a href="https://publications.waset.org/abstracts/search?q=Zanda%20Kruma"> Zanda Kruma</a>, <a href="https://publications.waset.org/abstracts/search?q=Fredijs%20Dimins"> Fredijs Dimins</a>, <a href="https://publications.waset.org/abstracts/search?q=Inta%20Krasnova"> Inta Krasnova</a>, <a href="https://publications.waset.org/abstracts/search?q=Daina%20Karklina"> Daina Karklina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Apple juice is the main raw material for cider production. In this study apple juices obtained from 14 dessert and crab apples grown in Latvia were investigated. For all samples total phenolic compounds, tannins and individual phenolic compounds content were determined. The total phenolic content of different variety apple juices ranged from 650mg L-1 to 4265mg L-1. Chlorogenic acid is the predominant phenolic compound in all juice samples and ranged from 143.99mg L-1 in ‘Quaker Beauty’ apple juice to 617.66mg L-1 in ‘Kerr’ juice. Some dessert and crab apple juices have similar phenolic composition, but in several varieties such as ‘Cornelie’, ‘Hyslop’ and ‘Riku’ it was significantly higher. For cider production it is better to blend different kinds of apple juices including apples rich in high phenol content ('Rick', 'Cornelie') and also, for successful fermentation, apples rich in sugars and soluble solids content should be used in blends. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apple%20juice" title="apple juice">apple juice</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20cluster%20analysis" title=" hierarchical cluster analysis"> hierarchical cluster analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cider%20production" title=" cider production"> cider production</a> </p> <a href="https://publications.waset.org/abstracts/7885/variation-of-phenolic-compounds-in-latvian-apple-juices-and-their-suitability-for-cider-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7885.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">429</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Improvements of the Difficulty in Hospital Acceptance at the Scene by the Introduction of Smartphone Application for Emergency-Medical-Service System: A Population-Based Before-And-After Observation Study in Osaka City, Japan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuke%20Katayama">Yusuke Katayama</a>, <a href="https://publications.waset.org/abstracts/search?q=Tetsuhisa%20Kitamura"> Tetsuhisa Kitamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Kosuke%20Kiyohara"> Kosuke Kiyohara</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumito%20Hayashida"> Sumito Hayashida</a>, <a href="https://publications.waset.org/abstracts/search?q=Taku%20Iwami"> Taku Iwami</a>, <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Kawamura"> Takashi Kawamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Takeshi%20Shimazu"> Takeshi Shimazu </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Recently, the number of ambulance dispatches has been increasing in Japan and it is, therefore, difficult to accept emergency patients to hospitals smoothly and appropriately because of the limited hospital capacity. To facilitate the request for patient transport by ambulances and hospital acceptance, the emergency information system using information technology has been built up and introduced in various communities. However, its effectiveness has not been insufficiently revealed in Japan. In 2013, we developed a smartphone application system that enables the emergency-medical-service (EMS) personnel to share information about on-scene ambulance and hospital situation. The aim of this study was to assess the introduction effect of this application for EMS system in Osaka City, Japan. Methods: This study was a retrospective study with population-based ambulance records of Osaka Municipal Fire Department. This study period was six years from January 1, 2010 to December 31, 2015. In this study, we enrolled emergency patients that on-scene EMS personnel conducted the hospital selection for them. The main endpoint was difficulty in hospital acceptance at the scene. The definition of difficulty in hospital acceptance at the scene was to make >=5 phone calls by EMS personnel at the scene to each hospital until a decision to transport was determined. The definition of the smartphone application group was emergency patients transported in the period of 2013-2015 after the introduction of this application, and we assessed the introduction effect of smartphone application with multivariable logistic regression model. Results: A total of 600,526 emergency patients for whom EMS personnel selected hospitals were eligible for our analysis. There were 300,131 smartphone application group (50.0%) in 2010-2012 and 300,395 non-smartphone application group (50.0%) in 2013-2015. The proportion of the difficulty in hospital acceptance was 14.2% (42,585/300,131) in the smartphone application group and 10.9% (32,819/300,395) in the non-smartphone application group, and the difficulty in hospital acceptance significantly decreased by the introduction of the smartphone application (adjusted odds ration; 0.730, 95% confidence interval; 0.718-0.741, P<0.001). Conclusions: Sharing information between ambulance and hospital by introducing smartphone application at the scene was associated with decreasing the difficulty in hospital acceptance. Our findings may be considerable useful for developing emergency medical information system with using IT in other areas of the world. <p class="card-text"><strong>Keywords:</strong> <a
