Digital video analysis of a multimedia product
No full textThis paper begins by describing VideoSearch, a recently developed multimedia software product designed as a research tool to allow researchers to digitise and analyse video on a computer. Codes and labels can be linked to any segment of a digitised video. Identified segments of the video can be recalled at any time. Because the program stores video in a digital format on a hard disk, access and playback of any video segment is almost instantaneous. Simple summary statistics are also available. Next the paper reports on how this product has been used to precisely categorise how students use a multimedia product. The allocation of time to different student activities in formal university settings, has been a subject of interest to researchers in recent years. For example, in a study of the distribution of time devoted to a variety of learning activities, Laurillard found that 'attending' was by far the most common activity. By contrast, anyone who has observed a child playing on a video arcade or Sega/Nintendo game will have noticed that the child has a very active role. However, there is very little time for the child to think in responding to the various challenges presented by the life-and-death situations. Children react rather than consider. For many of these programs, the educational value for the player is inversely proportional to the reaction time required. Both of these situations point to possible shortcomings in learning environments: the first in denying students an active role, the second, in denying a reflective role. The Cognition and Technology Group at Vanderbilt make the point that the learning environments they produce are meant to be explored and discussed at length rather than simply read or watched. In this vein, a program on assessment in mathematics was produced according to principles of situated learning or situated cognition. The program was designed to minimise students' keyboard responses, and maximise thoughtful, active reflection and discussion between the users. As part of an interpretive study into how students use interactive multimedia, small groups of students were videotaped using the assessment resource. VideoSearch was used to facilitate the analysis by coding excerpts of videotaped material into user- defined categories. The findings of the study suggest that an interactive multimedia program based on a situated learning model is conducive to promoting student activities other than attending behaviour. Unlike the traditional university courses mentioned by Laurillard and McNaught, with their emphasis on the transmission mode, the students using the assessment program were able to reflect and discuss their learning for a substantial portion of the available time
Development of an Atomic Force Microscope
No full textThis abstract presents the development of an Atomic Force Microscope (AFM) vertical scanner for surface topography measurements, which is composed of a single axis positioning stage with an integrated metrology system and AFM probe. The scanner is meant to track and measure a maximum topography step of 10 ?m with a measurement resolution of less then 0.1 nm and an uncertainty of less than 10 nm (1←) at a controllable bandwidth of at least 2 kHz.Precision and Microsystems EngineeringMechanical, Maritime and Materials Engineerin
Concrete Flow in Diaphragm Wall Panels: A Full-Scale In-Situ Test
No full textFlow processes, taking place during the concreting of diaphragm wall panels (D-wall panels), are of great importance for the quality of the wall. During this phase, the bentonite, present in the excavated trench, should be completely replaced by concrete in a controlled way. In literature several cases are described in which this process resulted in bentonite inclusions in the panel. These inclusions often lead to severe problems, like leakages, for the building pit to be excavated within the diaphragm wall panels. Beside the risks for the building pit, leakages caused by bentonite inclusions can also have large consequences for nearby constructions. In this article, set up and results of a full-scale diaphragm wall test are described. Conclusions are drawn with regard to the influence of several parameters on the flow process and subsequently on the quality of the wall and the risk on bentonite inclusions

Verification of BREAKWAT for berm breakwaters and low-crested structures
No full textThis report describes the verification of the model on dynamic stability for berm breakwaters. The model runs on a pc and is called BREAKWAT. The data received from various people allover the world contained not only berm breakwaters, but also dynamically stable low-crested structures. The title of the report was therefore changed to "Verification of BREAKWAT for berm breakwaters and low-crested structures". The calculations were performed and the report was written by Dr. J.W. van der Meer of Delft Hydraulics
