In operational flood defense, it is common practice to use sandbag systems. However, their installation is time-consuming as well as material- and labor-intensive. Sandbag replacement systems (SBRSs) can be installed in significantly shorter time and with less effort. However, owing to the lack of confidence in their functionality, they are only used to a limited extent. Testing and certifying such innovative systems according to defined criteria is supportive in promoting their use in flood defense. In order to test SBRSs and as a first step toward systematic tests, the Institute for Hydraulic and Coastal Engineering of the Bremen University of Applied Sciences, Germany (IWA) has set up a test facility in which defined test series can be carried out with different SBRSs on an underlying surface of turf. The focus of the test series is on installation time, possible water head, system stability, and seepage rates when in use. A conventional sandbag dam was used as reference in order to compare the test results with the different SBRSs. Test series show that damming with SBRSs has a clear advantage over the use of sandbags in terms of the time it takes to put them in place and comparable values of seepage rates and water heads. In order to professionally promote the spread of SBRSs in operational flood protection, it is recommended to introduce the certification of SBRSs, since they are technical systems whose functional capability must be proven before their use in an emergency. Together with existing international certification schemes, the test series that were carried out deliver a basis for developing a specific testing scheme for SBRSs.

In this chapter we present results of a project in the field of groupware systems. Munich University of Applied Sciences has set up an initiative called IT-Forum to coordinate IT activities across its 14 different departments. As part of this initiative a groupware system was developed on the basis of the Web application server ZOPE and the database mySQL. The objective of this project was to use the groupware systems operatively as communication platform within the IT-Forum and in project-orientated student courses. Furthermore the development and use of the application has been accompanied by some research work in the field of groupware systems. The main focus of this chapter is to describe this groupware system and report some experience of the use of it.

Instant messaging (IM) is the term used to describe the technology through which ‘users can set up a list of partners who will be able to receive notes that pop up on their screens the moment one of them writes and hits the send button’. While early use could be described as mainly for fun, IM today is a serious communication medium. Remarkably, it seems that educational institutions have been doing very little with it, while several studies indicate that it could indeed be a valuable tool in education. As a first step towards a better understanding of the educational use of IM, we want to gain insights in how students currently use IM and what opportunities they themselves see for the medium. To that end we conducted a survey among students of the Fontys University of Applied Sciences in The Netherlands. A large majority of the participating students indicated using IM for their studies. Also, when asked about their demands for a possible educational implementation, the majority were positiveDOI: 10.1080/09687760701470973

Engineering Pedagogy

Entrepreneurship education is quite a novel phenomenon that is gaining increasing importance in academia and practice alike. Entrepreneurship education aims to provide the necessary skills and knowledge that enable students to successfully found a new venture. Hitherto entrepreneurship education has not received much attention in engineering pedagogy. This finding is quite surprising because through proper entrepreneurship education engineers can be enabled to exploit entrepreneurial opportunities that result from technological innovation. Thus, we argue that entrepreneurship education should be a cornerstone in engineering education. The paper introduces the ‘Entrepreneurial Campus Villach’ located at the Carinthia University of Applied Sciences (CUAS). The campus is among the first in Austria that provide an extensive and scientifically sound entrepreneurship program. The campus focusses on the four core areas 1) research, 2) teaching, 3) coaching and support, and 4) infrastructure. The paper provides insights for other university and institutions that aim to set up similar concepts.

Blade Tip

The acoustical characteristics of cooling fans are an essential criterion of product quality in the automotive industry. Fan modules have to suffice growing customer expectations which are reflected in the comfort requirements set by car manufacturers around the world. In order to locate dominant acoustic sources and to reduce the noise emission generated by a shrouded fan configuration, numerical simulations and experimental investigations are performed. The working approach considers variously modified fan geometries and their evaluation regarding arising vortex flow phenomena and their effect on a decreased sound pressure level (SPL) in consideration of an improvement or the constancy of aerodynamic fan performance. Particular emphasis lies on the analysis of secondary flows in the blade tip region by post-processing CFD-results. Due to the large number of geometrical modifications investigated and the importance of highly resolved eddy structures, a hybrid approach is chosen by applying the SAS-SST turbulence model in URANS simulations. The SAS (Scale Adaptive Simulation) delivers LES (Large Eddy Simulation) content in unsteady regions of a RANS-simulation and exhibits not nearly the high computational effort needed to perform a full scale LES. An assessment of the actual propagation of noise emission into the far-field is made by performing experimental investigations on the most promising modifications. The acoustic measurements are carried out in a fan test stand in the anechoic chamber of Duesseldorf University of Applied Sciences. The aerodynamic performance is measured in a fan test rig with an inlet chamber setup in accordance to ISO 5801. The measured acoustical and aerodynamic performances are validated by the industrial partner. The results of the acoustic measurements are in turn utilized to determine indicators of noise radiation in the numerical simulation. Within this work an innovative geometry modification is presented which can be implemented into shrouded fan configurations with backward-skewed blades. The new design exhibits a reduced SPL (A-weighted) of approx. 4 dB over the entire operating range while showing no significant deterioration on the aerodynamic performance. While the design was registered for patent approval cooperatively by the industrial partner and Duesseldorf University of Applied Sciences, further investigations regarding variations of design parameters are performed and presented in this paper. All numerical simulations are performed with ANSYS CFX, a commercial solver widely spread in the industry. Methods similar to those shown in this work can be implemented in the design phase of axial fans in order to develop acoustically optimized fan geometries.

The family-friendly university audit (“audit familiengerechte hochschule”) is studied. The audit is available to German universities in order to support a familyfriendly working environment. Practices of an auditor coordinating several workshops for rectorate, HR department and functionaries, as well as representatives of all university groups are considered. The experience of the auditing at the University of Applied Sciences – Public Administration and Finance, Ludwigsburg is analyzed.
