CARIN en GPS: De combinatie van dead-reckoning, map-matching en satellietplaatsbepaling in een hybride autonavigatiesysteem
No full textDe laatste jaren doen zich verscheidene ontwikkelingen voor in de autonavigatie. Eén van de ontwikkelingen wordt gevormd door het geïntegreerd gebruik van meerdere, elkaar aanvullende, positiesensoren in één hybride navigatiesysteem. Het CARIN autonavigatiesysteem van PHILIPS is gebaseerd op een combinatie van dead-reckoning (afgelegde afstand uit wielomwentelingen, richting van kompas) en map-matching (het intelligent gebruik van kaartinformatie, opgeslagen op CD). Aangezien het systeem, bijvoorbeeld bij gedeeltelijke afwezigheid van kaartinformatie, kan gaan driften, is het wenselijk een correctie te laten uitvoeren door een absolute positiesensor, zoals GPS. Dit onderzoek bestudeert de mogelijkheden en de haalbaarheid van een koppeling tussen CARIN en GPS aan de hand van een simulatiestudie. Daartoe werden diverse testritten uitgevoerd, waarbij GPS- en CARIN-waarnemingen m.b.v. tijdlabels ten opzichte van elkaar werden vastgelegd. Voor de daadwerkelijke koppeling werd een dynamisch model ontwikkeld , dat de gewogen oplossing bepaalt tussen de GPS en de CARIN positie-oplossing, op grond van hun foutenmodellen. Het blijkt dat GPS in bebouwde omgeving slecht functioneert, doordat afscherming van satellietsignalen optreedt. CARIN functioneert hier goed. Het aanvullende karakter van de twee systemen blijkt uit de omgekeerde situatie buiten het stedelijk gebied. Het dynamisch model weet de posities zo te combineren dat de nauwkeurigheid van de hybride oplossing in elke situatie groter is dan die van de systemen afzonderlijk.Civil Engineering and GeosciencesMathematische en fysische geodesi
The traffic safety of the Carin car information and navigation system IA-literature study: Main report
No full textReport of the Delft University of Technology, Department of Transportation Planning and Highway Engineering in assignment of Philips International B.V. Aim of the study was to determine the possible posi tive and negative effects on traffic safety of the Carin Car Information and Navigation system and to define requirements by which the possible negative effects are minimized or possibly eliminated and the possible positive effects are enhanced, thus making the overall effect of Carin on traffic safety a positive one. The Carin system has been analysed with the so-called phase model of the accident process. Possible positive effects that resulted from this analysis, are: avoidance of search behaviour, avoidance of detours, avoidance of unsafe locations and situa tions, and informa tion on the vehicle condition. Possible negative effects were: compact disc changing while driving, distraction by route guiding advices, untimely presentation of route guiding advices, obstruction of the driver's view, illegal route guiding advices, the reaction on a disregarding of a route guiding advice, and (part of) the system causing injuries in case of an accident. On an important part of the above subjects a literature study has been conducted. The findings are discussed and gaps in the present knowledge indicated. Priorities for further study are presented.Transport & PlanningCivil Engineering and Geoscience

Every Second Is a Life: Ulla-Carin Lindquist’s Rowing Without Oars
No full text© The Author(s) 2019. Ulla-Carin Lindquist’s Rowing Without Oars relates a life constrained by illness, in which one’s sense of “I am” becomes increasingly faint. She depicts how physical losses can inadvertently open opportunities to explore humanity’s “potential consciousness.” In seeking an answer to the question, “Who am I become to live well in this new world?” Lindquist demonstrates what it means to “become fully human, and everything that the person can become.” She captures this movement toward “potential consciousness” through simple, lyrical language and artfully constructed grammar and syntax that is devoid of deception
The traffic safety of the Carin car information and navigation system: Summary report
No full textReport of the Delft University of Technology, Department of Transportation Planning and Highway Engineering in assignment of Philips International B.V. The Carin Car Information and Navigation system has been analysed on its possible positive and negative effects on traffic safety. Requirements have been defined by which the possible negative effects should be minimized or possibly eliminated and the possible positive effects enhanced. Possible positive effects that resulted from this analysis are: avoidance of search behaviour, avoidance of detours, avoidance of unsafe locations and situations, and information on the vehicle condition. Possible negative effects were: compact disc changing while driving, distraction by route guiding advices, untimely presentation of route guiding advices, obstruction of the driver's view, illegal route guiding advices, the reaction on a disregarding of a route guiding advice, and (part of) the system causing injuries in case of an accident. On an important part of the above subjects a literature study has been conducted. The findings are discussed and gaps in the present knowledge indicated. The in-car presentation of route guiding advices may distract a driver from his tasks to keep course and to account for the other traffic and the traffic environment. A distraction by route guiding pictogrammes from the task to keep course can be avoided by selecting pictogrammes that require a shorter interpretation time than the available time period between two successive course corrections. In a laboratory study on the distraction from the task to account for the other traffic, it was found tha t deteriora tions mainly occurred in incident situations. The deteriorations are largest for stimuli from alocation right in front of the car, especially for elder drivers. Under circumstances all pictogrammes caused deteriorations. In difficuit situations complex pictogrammes cause more deteriorations than simple ones. Most sensitive to deteriorations are elderly drivers and young males when driving at high speeds.Transport & PlanningCivil Engineering and Geoscience

Pharmacokinetic research in children: an analysis of registered records of clinical trials.
No full textBACKGROUND: Reported off-label/unlicensed prescribing rates in children range from 11% to 80%. Research into pharmacokinetic profiles of children's medicines is essential in the creation of more knowledge on the safety and efficacy of medicines in children. This study investigated how often pharmacokinetic data are collected in clinical trials of medicines in children by analysing registered records of clinical trials. METHODS: The registered records of all clinical trials in children that were recruiting on 22 May 2009 were identified on the International Clinical Trials Registry Platform using a Clinical Trials in Children search filter. The records of trials in children below 12 years of age, in which the intervention was one or more medicines, were assessed for evidence that pharmacokinetic data would be collected. RESULTS: Of 1081 eligible trial records, 257 (24%) declared that pharmacokinetic data would be collected. Of these trials, 199 (77%) recruited in Northern America; recruitment in all other regions was below 20%. Trials recruited most often in children over 2 years of age (74%), and least often in newborn infants (32%). Most trials researched medicines in the field of cancer (29%). Trials investigated one-third of the medicines that were indicated as a priority for pharmacokinetic research by the European Medicines Agency. CONCLUSIONS: There is a need for increased knowledge of the pharmacokinetic profiles of children's medicines. The amount of currently ongoing pharmacokinetic research does not seem to address adequately the lack of knowledge in this area. This study sets a baseline for monitoring of future progress on the amount of ongoing pharmacokinetic research in children

The accuracy, precision and sustainability of different techniques for tablet subdivision: breaking by hand and the use of tablet splitters or a kitchen knife. Int J Pharm 2014;466:44-51.Abstract Van Riet-Nales DA, Schobben AFAM, Vromans H, Egberts ACG, Rademaker CMA. Child-friendly medicines. Huisarts Wet 2017;60(1):15-9. Adequate drug treatment in children implies the use of an appropriate medicine, in the correct dose and in a formulation that the child can and will accept. For a long time, little was known about the relationship between aspects related to the drug product design, such as the type of the dosage form, the excipients, the instructions for use, and treatment outcomes in children. Moreover, the currently available medicines may cause problems. This PhD research project investigated child-friendly medicines. Findings showed that medicines are not always licensed or appropriate for children, and that there are differences in drug form of different brands containing the same active ingredient, such as bromhexine syrups with or without alcohol. Young children can be treated not only with liquids and powders, but also, and perhaps even better, with small mini-tablets. This PhD study showed that parents often administer medicines in an incorrect manner, for example by mixing a mini-tablet or powder with food or liquid on a spoon. This occurs more often if the child does not readily take the medicine. As many tablet cutters do not cut tablets into equal halves, scored tablets can best be broken manually
