Die Anwendung des 3-2-1 Modells didaktischer Elemente in der Hochschulpraxis

Im Verlauf einer universitätsweiten Förderinitiative wurde für die Lehrveranstaltung Betonbau ein Projekt durchgeführt, das mithilfe Neuer Medien versucht, die Lehre an der Hochschule nachhaltig zu verbessern. In dieser Veröffentlichung wird über die Entwicklung von interaktiven Lernobjekten (ILO) berichtet, die streng nach den Gesichtspunkten des 3-2-1 Modells didaktischer Elemente nach Kerres (2001) aufgebaut wurden. Die Umsetzung, sowohl in technischer als auch didaktischer Hinsicht, sowie die Implementierung im Curriculum wird detailliert beschrieben. Eine Diskussion über eine mögliche Effizienzsteigerung in der Lehre rundet diese Veröffentlichung ab.(DIPF/Orig.

Drivers’ Interaction with Adaptive Cruise Control on Dry and Snowy Roads with Various Tire-Road Grip Potentials

This study investigates drivers’ interaction with Adaptive Cruise Control (ACC) in different road conditions and identifies areas of improvement. Ninety-six drivers drove with the ACC in a driving simulator showing either a summer scenery and a dry road with high grip potential or a winter scenery with a snowy road and reduced grip potential. The results show that on snowy roads the drivers set in average a lower ACC speed and preferred a larger ACC time gap. Drivers’ workload and effort were higher when using the ACC on snowy as compared to dry roads. Generally, the use of a shorter ACC gap resulted in lower ratings of comfort, safety, and trust and higher ratings of mental workload and effort in both dry and snowy road conditions. The drivers judged that ACC was braking too late and maintained a too short gap to the forward vehicle, especially when the ACC was set to 1 second as compared to a 1.8-second time gap. A future adaptation of ACC’s control strategy to reduced tire-road grip potential would not only improve comfort and user acceptance of the human driver but also increase the potential to react in emergency situations with braking or evasive steering

Human papillomaviruses in Western Africa: prevalences and risk factors in Burkina Faso

PurposeCervical cancer is the most common cancer in women in low income countries. Certain oncogenic types of human papillomaviruses are causally associated with the cervical cancer. To ensure effective primary prevention through the introduction of a national vaccination program in Burkina Faso, information about the disease burden of HPV infection in the country is of great importance.MethodsIn the present work the prevalence of 54 different HPV types and 18 other sexually transmitted infection as well as the predominant risk factors for the development of cervical cancer were investigated in Ouagadougou. A cross-sectional study on two populations without (n=471) and with known cervical dysplasia (n=39) was carried out between October 2013 and March 2014. Retrospectively, data on possible and secured risk factors of the cervical carcinoma were collected. The participants were examined gynecologically and a vaginal lavage was taken, which was molecular genetically examined for 54 different human papillomavirus genotypes and 18 other STIs.ResultsThe prevalence of human papillomavirus was 42.3% (188/444) in the first study population and 87.2% (34/39) in the second study population. The immunization coverage would be 24.5% of the HPV types and 33.9% of the high-risk HPV types with quadrivalent vaccine Gardasil (R). The nonavalent vaccine Gardasil (R) 9 (9vHPV) would cover 37.3% of all HPV types and 57.1% of high-risk HPV types. ConclusionThe prevention of infection with human papillomaviruses by vaccination is expected to result in a drastic reduction in the morbidity and mortality of the cervical cancer in Burkina Faso

Integrated tools for automatic design for testability

An increasing part of the overall costs of custom and semicustom integrated circuits has to be spent for test purposes, and therefore the integration of test and design seems to be a key of cost reduction. At the University of Karlsruhe a program system is currently developed supporting the design of testable circuits. The program system under work essentially solves three tasks: 1.) Selection of an economical test strategy. 2.) Implementation of necessary circuit modifications in order to enhance testability, retaining the circuit function by construction. 3.) Generation of the test program

Building a Driving Simulator with Parallax Barrier Displays

In this paper, we present an optimized 3D stereoscopic display based on parallax barriers for a driving simulator. The overall purpose of the simulator is to enable user studies in a reproducible environment under controlled conditions to test and evaluate advanced driver assistance systems. Our contribution and the focus of this article is a visualization based on parallax barriers with (I) a-priori optimized barrier patterns and (II) an iterative calibration algorithm to further reduce visualization errors introduced by production inaccuracies. The result is an optimized 3D stereoscopic display perfectly integrated into its environment such that a single user in the simulator environment sees a stereoscopic image without having to wear specialized eye-wear

DFG Funding Programme Open Access Publishing - Report about the Funding

The report "Open Access Publishing" contains extensive information from an empirical evaluation of the funding programme with which the DFG has been supporting the gold route of open access since 2010. The study is based on a bibliometric analysis carried out by Forschungszentrum J&uuml;lich. An online survey was also conducted among 82 funded and non-funded institutions, which shared both their experiences of funding and assessments of future needs in relation to open access funding from the DFG. The surveys were supplemented by more detailed interviews. This part of the evaluation was carried out by JOANNEUM RESEARCH. Between 2010 and 2016, 45 universities received funding through the programme. During this period, these institutions published almost 12,000 articles through gold open access with the help of the programme (including the universities&#39; own contributions). Most of the funded articles were in the life sciences. The number of articles funded each year rose steadily throughout the period. The effects of funding in the Open Access Publishing programme can be seen in the organisation and structures of the institutions. In addition to the establishment of workflows and funds to cover costs, the funding promoted measures to record and monitor publication figures. Over half of the funding recipients surveyed used the DFG funds to bring acquisition and open access organisationally closer together or merge them, and to stimulate the transformation from a subscription to an open access model.</p
