echolocation or “bio-sonar” to orient and find prey in the dark.
They emit short high frequency sound pulses and listen for the echoes
from surroundings to orient in space. Bats from different families emit
either through the mouth or through the nose. Bats emitting sound
nose have elaborate skin folds or “nose-leaves” around the
nostrils. The shape and size of the sound emitting structures (mouth or
is believed to strongly affect the directionality or shape of the
beam. The shape of the sound beam will subsequently strongly affect the
reflected “echo-picture” of the scene. A broad beam will ensonify
objects within a wide angle, whereas a narrow beam will restrict the
bat to a
narrow angle of view, but perhaps reach further ahead than the broader
Thus, the received echo is dependent on the outgoing sound. However,
returning echo also depends on the shape and size of ears. This
referred to as “head-related-transfer-function” (HRTF) and is well
described for human listening, but not at all for bats in spite of the
importance, which is reflected in the very diverse and sometimes
morphology of bat faces.
The goal of the
project is therefore to record and use echolocation sounds from real
species to determine the effect of morphology on directionality of the
beam and HRTF of returning echoes. Based on these data we want to
algorithms to effectively simulate the sound in 3-D. 3-D simulations of
fields will be used for implementing bio-mimetic robots using sound
to orient in space and to discriminate between objects.
An EU-funded (FP7)
project, ChiRoPing (www.ChiRoPing.org )
focuses on the engineering aspects of building bio-mimetic bat-robots,
models four bat species with different morphology and echolocation
overlapping prey capture strategies. The ChiRoPing project seeks to
physical and mathematical models of the bats and compare structure,
and performance to the real bats. Thus, this present project will
and complement the ChiRoPing project. Biology, SDU, also has a Marine
Facility, “Fjord and Baelt”, with captive trained porpoises, which
gives a unique opportunity to compare performance of bio-sonar systems
and water and study how structure is linked to function in two media
different constraints on the systems.
This project is
offered within the research training programme SNAK. The project is

Fellowships in Natural Sciences – Job ID 083021 – Re-announcement
of Projects 6 and 7
of Science offers
two PhD Research Fellowships at the Faculty of Science available as of
The fellowships may be sought by students who wish to obtain a PhD
either with or without a previous Master's degree, in a field relevant
or more of the below mentioned PhD projects.
The PhD programme at the Faculty of Science can be completed as a
study with a previous Master’s degree or as a four-year study without a
previous Master’s degree. Applicants without a relevant Master's degree
must have passed a minimum of 240 ECTS-points (Bachelor’s degree plus
year (60 ECTS-points) of graduate study).
The fellowships are available within the following two projects:
6) Sound localizing robot
7) Echolocation in bats – the role of ear and face morphology for sound
emission and perception
Further information concerning the projects: Please contact one or more
supervisors mentioned under the project descriptions.
Further information about the PhD study can be found at the homepage
of the University.
Research Fellowship is
salaried in accordance with the Danish State Education Grant and Loan
Authority, and with the agreement on salaried PhD students between the
of Finance and the Danish Confederation of Professional Associations,
The successful candidates will be enrolled at this University in
with Faculty regulations and the Danish Ministerial Order on the PhD
at the Universities (PhD order).
Must be made in the form of a declaration of interest and should
• A letter stating the interest, motivation and qualifications for the
project in question (max two pages)
• Detailed CV, including personal contact information
• Certified copy of diploma
• Previous research experience and list of publications, if any.
Additional information may be requested and the application process may
an interview before the final decision is made.
The declaration of interest will be evaluated by a committee comprised
supervisor of the project and one or two members of the PhD Assessment
Committee at the Faculty. The Assessment Committee selects one or two
from each project who are each given one month to prepare a project and
research plan and an application for enrolment at the PhD School at the
