Future engineers: the intrinsic technology motivation of secondary school pupils
The supply of students motivated to study engineering in higher education is critical to the sector. Results are presented from the âMindsets STEM Enhancement Projectâ. Fifty-seven new resources packs, designed to improve STEM education in Design and Technology, were given to schools across London. A modified Intrinsic Motivation Inventory questionnaire measured pupilsâ (n = 458) motivation towards technology. The results show that although pupils have positive reactions to the technology content within Design and Technology lessons, the type of STEM resources and lessons created through the project had made no significant difference on pupilsâ interest/enjoyment towards technology. This suggests standalone resources do not improve pupil motivation. The impact of this work to engineering higher education is that the existing levels and the inability to improve pupil motivation in technology at school could be a factor affecting the pursuit of a technology or engineering related education or career

Applying Laser Cutting Techniques Through Horology for Teaching Effective STEM in Design and Technology
This paper explores the pedagogy underpinning the use of
laser manufacturing methods for the teaching of science,
technology, engineering and mathematics (STEM) at key
stage 3 design and technology. Clock making (horology)
has been a popular project in design and technology
(D&T) found in many schools, typically it focuses on
aesthetical design elements. This paper describes a new
project, which has been developed to enhance the STEM
content of a horology project through advanced utilisation
of laser cutting machinery. It allows pupils to produce their
own products from self-made mechanical timing
mechanisms. The central aim is to strengthen the
application of the underlying technology of mechanisms
and the manufacturing capability of laser cutting
technology in D&T.
Trials with schools have shown success in gaining pupilsâ
interest in STEM and provided feedback to improve the
project. It has highlighted limits when delivering the
engineering and maths content with teachers from nontechnology
backgrounds. The paper discusses this
limitation through subject pedagogy, categorisation of
teacher knowledge, and teaching effectiveness through
experiential and problem-based learning approaches
Momentum dependence of the excitons in pentacene
We have carried out electron energy-loss investigations of the lowest singlet
excitons in pentacene at 20 K. Our studies allow to determine the full exciton
band structure in the a*,b* reciprocal lattice plane. The lowest singlet
exciton can move coherently within this plane, and the resulting exciton
dispersion is highly anisotropic. The analysis of the energetically following
(satellite) features indicates a strong admixture of charge transfer
excitations to the exciton wave function.Comment: 13 pages, 4 figure
Tsunami-Related Data: A Review of Available Repositories Used in Scientific Literature
Various organizations and institutions store large volumes of tsunami-related data, whose
availability and quality should benefit society, as it improves decision making before the tsunami
occurrence, during the tsunami impact, and when coping with the aftermath. However, the existing
digital ecosystem surrounding tsunami research prevents us from extracting the maximum benefit
from our research investments. The main objective of this study is to explore the field of data
repositories providing secondary data associated with tsunami research and analyze the current
situation. We analyze the mutual interconnections of references in scientific studies published in the
Web of Science database, governmental bodies, commercial organizations, and research agencies. A
set of criteria was used to evaluate content and searchability. We identified 60 data repositories with
records used in tsunami research. The heterogeneity of data formats, deactivated or nonfunctional
web pages, the generality of data repositories, or poor dataset arrangement represent the most
significant weak points. We outline the potential contribution of ontology engineering as an example
of computer science methods that enable improvements in tsunami-related data management

Bio-inspired motion detection in an FPGA-based smart camera module
Köhler T, Roechter F, Lindemann JP, Möller R. Bio-inspired motion detection in an FPGA-based smart camera module. Bioinspiration & Biomimetics. 2009;4(1):015008.Flying insects, despite their relatively coarse vision and tiny nervous system, are capable of carrying out elegant and fast aerial manoeuvres. Studies of the fly visual system have shown that this is accomplished by the integration of signals from a large number of elementary motion detectors (EMDs) in just a few global flow detector cells. We developed an FPGA-based smart camera module with more than 10000 single EMDs, which is closely modelled after insect motion-detection circuits with respect to overall architecture, resolution and inter-receptor spacing. Input to the EMD array is provided by a CMOS camera with a high frame rate. Designed as an adaptable solution for different engineering applications and as a testbed for biological models, the EMD detector type and parameters such as the EMD time constants, the motion-detection directions and the angle between correlated receptors are reconfigurable online. This allows a flexible and simultaneous detection of complex motion fields such as translation, rotation and looming, such that various tasks, e. g., obstacle avoidance, height/distance control or speed regulation can be performed by the same compact device
