Developed and owned by the United States Department of Defense\r\n(DOD), its primary purpose is the determination of platform position and velocity as\r\nwell as dissemination oftime. Today, the number of applications in which GPS is used\r\ncontinues to grow, including those involving harsh environments and high dynamics that\r\ncannot be replicated cost-effectively. One such application is the use of GPS in High\r\nDynamic and Missile Application (HDMA).\r\nGPS simulators have become an indispensable tool in the GPS industry. An\r\nalmost limitless variety ofscenarios can be simulated to test a receiver's software before\r\nit goes into production. A GPS simulator is also helpful in debugging problems that\r\noccur in locations that are not easily accessible, since any geographic location can be\r\nprogrammed into the scenario. Once the scenario has been designed, it can be played\r\nback over and over again. Any scenario can be modified in a short time, contributing to\r\nbetter efficiency in testing.\r\nGPS simulators are especially valuable for testing receiver performance in high\r\ndynamic situations. Many companies and government agencies involved in the\r\nlaunching of satellites are using GPS to track the launch vehicle's velocity and\r\ntrajectory. With the simulator, the software in the receiver can be tested exhaustively\r\nbefore incurring the cost oflaunching a rocket. Problems can be corrected before a live\r\nlaunch is initiated. 99% ofthe GPS receivers in the world today could not possibly track\r\nany satellites in this type of application. Therefore, tests are needed to determine\r\nwhether tracking is even possible. Using GPS in these types of applications is a \r\nrelatively new concept due to the fact that the technology has historically been quite\r\nlimited. A $7,500 dollar receiver is replacing equipment that takes $250,000 a day to\r\noperate in some cases. As GPS receivers are further tested and qualified for various\r\nprograms, this technology will undoubtedly expand. GPS simulators are being used to\r\nexpand the perceived limits ofthe technology and extensive research in these areas is\r\ndriving the development for an entire industry. The simulator can also be set up to test\r\nthe performance ofthe launch on any given day in the future. This gives the advantage\r\nofusing the best possible constellation for the launch window.\r\nOne ofthe potential drawbacks of using a GPS simulator is that it can measure\r\nthe performance ofthe software only. While this reduces the number ofpossible causes\r\nfor failures, the physical strains expected for a given application must be simulated\r\nconventionally using vibration tables and other equipment ifnot on a live mission itself.\r\nCommonly various agencies have been unable to perform simulations and are forced to\r\ndo the testing on live rockets. Often these results are showing positive results while\r\nvarious simulations predict failure. This is currently driving research into better ways to\r\nsimulate missions accurately using a number oftest procedures and equipment.\r\nA flight test of the Vandal rocket was made on December 3, 1997, Universal\r\nCoordinated Time (UTC). An Ashtech G-12 GPS receiver was placed on the rocket for\r\ndata collection throughout all stages ofthe flight. The flight was successful with the GPS\r\nreceiver maintaining lock on all visible satellites throughout the flight. Both the US\r\nDepartment ofDefense and NASA were unable to replicate this flight in a laboratory on\r\na GPS simulator. This thesis will show that a simulator can be used to test the firmware\r\nof the receiver for HDMA maneuvers.","note":"","tags":""} , {userid:"loretta.delmercato", "articletype":"article","pages":"186-190","author":"Anke Kolbe, Loretta L del Mercato, Azhar Z Abbasi, Pilar Rivera-Gil, Sekineh J Gorzini, Wim H C Huibers, Bert Poolman, Wolfgang J Parak, Andreas Herrmann","year":"2011","title":"De Novo Design of Supercharged, Unfolded Protein Polymers, and Their Assembly into Supramolecular Aggregates","month":"JAN 17 2011","journal":"MACROMOLECULAR RAPID COMMUNICATIONS","publisher":"","volume":"32","number":"2","note":"Times Cited: 14","tags":"","booktitle":"","editor":"","abstract":"","address":"","school":"","issn":"1022-1336","doi":"10.1002\/marc.201000491","isi":"WOS:000287115000007","pubmed":"","key":"Kolbe2011","howpublished":"","urllink":"","refid":42,"weight":42} , {userid:"ahmad_hatim.sulaiman", "refid":"26","repocollections":"","attachment":"","_thumb":"","articletype":"article","sectionheading":"","title":"Escitalopram in the Treatment of Malaysian Patients with Obsessive-compulsive Disorder","year":"2008","author":"A Hatim, J S Gill, S T Jambunathan, T H Yen, M Ariff, O M Lemming, M Z Azhar","journal":"Hong Kong J Psychiatry","volume":"18","number":"","pages":"152-157","month":"","doi":"","pubmed":"","pdflink":"","urllink":"http:\/\/easap.asia\/journal_file\/0804_V18N4-p152-7.pdf","abstract":"Objective: This post-hoc analysis examined the efficacy and tolerability of escitalopram in the prevention of relapse in Malaysian patients with obsessive-compulsive disorder. Participants and Methods: In Malaysia, 47 patients with obsessive-compulsive disorder were treated with open-label escitalopram (10 mg or 20 mg\/day) for 16 weeks, after which the 34 responders (Yale-Brown Obsessive Compulsive Scale total decrease score, \u00e2\u0089\u013d 25%) were randomised to placebo or escitalopram for 24 weeks, using a double-blind protocol. Results: The primary efficacy analysis suggested a trend in favour of escitalopram treatment with respect to time to relapse (log-rank test, p = 0.07). A higher proportion of patients relapsed after placebo treatment (5 of 14, 36%) than with escitalopram treatment (2 of 20, 10%) [Fisher\u00e2\u0080\u0099s exact test, 2-sided; p = 0.10]. The risk of relapse was 4-fold higher for placebo than escitalopram treatment (p = 0.09). During the double-blind period, the proportion of patients reporting treatment-emergent adverse events was comparable in the 2 groups (10% in the escitalopram group vs. 14% in the placebo group); no serious events being reported. Conclusions: This post-hoc subgroup analysis suggests that escitalopram is well tolerated in Malaysian patients with obsessive-compulsive disorder and appears to confer an advantage over placebo, in terms of time to relapse and other efficacy variables.","note":"","tags":"Citalopram; Obsessive-compulsive disorder; Recurrence; Treatment outcome","weight":26,"publisher":"","booktitle":"","editor":"","address":"","school":"","issn":"","isi":"","key":"Hatim2008","howpublished":""} , {userid:"okke.batelaan", "refid":"145","repocollections":"","attachment":"","_thumb":"","articletype":"article","sectionheading":"","title":"Twenty-three unsolved problems in hydrology (UPH) \u2013 a community perspective","year":"2019","author":"G\u00fcnter Bl\u00f6schl, Marc F P Bierkens, Antonio Chambel, Christophe Cudennec, Georgia Destouni, Aldo Fiori, James W Kirchner, Jeffrey J McDonnell, Hubert H G Savenije, Murugesu Sivapalan, Christine Stumpp, Elena Toth, Elena Volpi, Gemma Carr, Claire Lupton, Jos\u00e8 Salinas, Borb\u00e1la Sz\u00e9les, Alberto Viglione, Hafzullah Aksoy, Scott T Allen, Anam Amin, Vazken Andr\u00e9assian, Berit Arheimer, Santosh K Aryal, Victor Baker, Earl Bardsley, Marlies H Barendrecht, Alena Bartosova, Okke Batelaan, Wouter R Berghuijs, Keith Beven, Theresa Blume, Thom Bogaard, Pablo Borges de Amorim, Michael E B\u00f6ttcher, Gilles Boulet, Korbinian Breinl, Mitja Brilly, Luca Brocca, Wouter Buytaert, Attilio Castellarin, Andrea Castelletti, Xiaohong Chen, Yangbo Chen, Yuanfang Chen, Peter Chifflard, Pierluigi Claps, Martyn P Clark, Adrian L Collins, Barry Croke, Annette Dathe, Paula C David, Felipe P J de Barros, Gerrit de Rooij, Giuliano Di Baldassarre, Jessica M Driscoll, Doris Duethmann, Ravindra Dwivedi, Ebru Eris, William H Farmer, James Feiccabrino, Grant Ferguson, Ennio Ferrari, Stefano Ferraris, Benjamin Fersch, David Finger, Laura Foglia, Keirnan Fowler, Boris Gartsman, Simon Gascoin, Eric Gaume, Alexander Gelfan, Josie Geris, Shervan Gharari, Tom Gleeson, Miriam Glendell, Alena Gonzalez Bevacqua, Mar\u00eda P Gonz\u00e1lez-Dugo, Salvatore Grimaldi, A B Gupta, Bj\u00f6rn Guse, Dawei Han, David Hannah, Adrian Harpold, Stefan Haun, Kate Heal, Kay Helfricht, Mathew Herrnegger, Matthew Hipsey, Hana Hlav\u00e1\u010dikov\u00e1, Clara Hohmann, Ladislav Holko, Christopher Hopkinson, Markus Hrachowitz, Tissa H Illangasekare, Azhar Inam, Camyla Innocente, Erkan Istanbulluoglu, Ben Jarihani, Zahra Kalantari, Andis Kalvans, Sonu Khanal, Sina Khatami, Jens Kiesel, Mike Kirkby, Wouter Knoben, Krzysztof Kochanek, Silvia Kohnov\u00e1, Alla Kolechkina, Stefan Krause, David Kreamer, Heidi Kreibich, Harald Kunstmann, Holger Lange, Margarida L R Liberato, Eric Lindquist, Timothy Link, Junguo Liu, Daniel Peter Loucks, Charles Luce, Gil Mah\u00e9, Olga Makarieva, Julien Malard, Shamshagul Mashtayeva, Shreedhar Maskey, Josep Mas-Pla, Maria Mavrova-Guirguinova, Maurizio Mazzoleni, Sebastian Mernild, Bruce Dudley Misstear, Alberto Montanari, Hannes M\u00fcller-Thomy, Alireza Nabizadeh, Fernando Nardi, Christopher Neale, Nataliia Nesterova, Bakhram Nurtaev, Vincent O Odongo, Subhabrata Panda, Saket Pande, Zhonghe Pang, Georgia Papacharalampous, Charles Perrin, Laurent Pfister, Rafael Pimentel, Mar\u00eda J Polo, David Post, Cristina Prieto Sierra, Maria-Helena Ramos, Maik Renner, Jos\u00e9 Eduardo Reynolds, Elena Ridolfi, Riccardo Rigon, Monica Riva, David E Robertson, Renzo Rosso, Tirthankar Roy, Jo\u00e3o H M S\u00e1, Gianfausto Salvadori, Mel Sandells, Bettina Schaefli, Andreas Schumann, Anna Scolobig, Jan Seibert, Eric Servat, Mojtaba Shafiei, Ashish Sharma, Moussa Sidibe, Roy C Sidle, Thomas Skaugen, Hugh Smith, Sabine M Spiessl, Lina Stein, Ingelin Steinsland, Ulrich Strasser, Bob Su, Jan Szolgay, David Tarboton, Flavia Tauro, Guillaume Thirel, Fuqiang Tian, Rui Tong, Kamshat Tussupova, Hristos Tyralis, Remko Uijlenhoet, Rens van Beek, Ruud J van der Ent, Martine van der Ploeg, Anne F Van Loon, Ilja van Meerveld, Ronald van Nooijen, Pieter R van Oel, Jean-Philippe Vidal, Jana von Freyberg, Sergiy Vorogushyn, Przemyslaw Wachniew, Andrew J Wade, Philip Ward, Ida K Westerberg, Christopher White, Eric F Wood, Ross Woods, Zongxue Xu, Koray K Yilmaz, Yongqiang Zhang","journal":"Hydrological Sciences Journal","volume":"64","number":"10","pages":"1141-1158","month":"","doi":"10.1080\/02626667.2019.1620507","pubmed":"","pdflink":"","urllink":"https:\/\/doi.org\/10.1080\/02626667.2019.1620507","abstract":"This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through online media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focused on the process-based understanding of hydrological variability and causality at all space and time scales. Increased attention to environmental change drives a new emphasis on understanding how change propagates across interfaces within the hydrological system and across disciplinary boundaries. In particular, the expansion of the human footprint raises a new set of questions related to human interactions with nature and water cycle feedbacks in the context of complex water management problems. We hope that this reflection and synthesis of the 23 unsolved problems in hydrology will help guide research efforts for some years to come.","note":"","tags":"","weight":145,"publisher":"Taylor & Francis","booktitle":"","editor":"","address":"","school":"","issn":"0262-6667","isi":"","key":"Bl\u00f6schl2019","howpublished":"https:\/\/doi.org\/10.1080\/02626667.2019.1620507"} ] } ; ajaxResultsLoaded(_ajax_res);
