Data about our communication, our health, our whereabouts, our financial transactions, etc. are kept all over the place and it’s increasingly difficult to understand who uses what data for which purpose. Who is allowed access to such data, who makes decisions about us on the basis of it? How do privacy matters affect us? Karin Spaink will present trends in the collecting / use of personal data.

The Dutch word for enthousiastic is ‘bevlogen’. This word also has the word flying in it and it is the best word to describe Hester Bijl. On the 21st of April she stood before us, flapping her arms, showing us how the open and close movements of wings differ from each other. She was also mimicking what a butterfly does (clapping its wings) to give itself an extra push upwards.
Until now, people have made flying devices with stiff wings that do not work anything like the flapping wings you find in nature. An insect’s wing consists of a very thin membrane and blood vessels. The blood vains can swell up; this will influence the flight. Now a machine with flapping wings is created; the Delfly, a small insect-like flying device. Nobody really understands yet how flapping works. Simulation is used to get a grip on this subject, involving a lot of mathematics.
The Delfly can be geered up with a small camera. It can be used to monitor airports for example. If something is wrong, a whole swarm of them can gather. Or maybe they can even be put to use to check whether there are still people in a burning building! They are also great as toys.
As Hester told us, it will be unlikely that in the future we will board a plane that has flapping wings as well, because for big things other laws apply than for small things.
Even for someone not remotely interested in the subject this was a very interesting presentation; she captured the attention of everyone. She made complicated stuff comprehensible by comparing it with things that everyone can relate to; why don’t you stick your arm out of a car window, change the angle of your arm and see what happens?
At the end of the evening we had this fabulous cake to celebrate our 1st birthday!
On Friday April the 17th some British, Belgian and Dutch Girl Geek Dinner organizers met up in Amsterdam, during the Next Web ‘09 Conference.
(Clockwise L-R: Sarah Blow, Leen Segers, Imke Dielen, Marjon Wiendels, Melanie Rieback)
Excitingly, one of the attendees was Sarah Blow, the founder of the international Girl Geek Dinner movement!
Sarah brought along a male friend, Chippy, who showed us a menagerie of mobile computing gadgets. (Videos of this is can be seen at the girlygeekdom blog and at Chippy’s blog). The Girl Geeks compared notes about the Dinners in their various locations. And Chippy now even wants to start his own Girl Geek Dinner in Bonn!
Flies are true acrobats in the air. They can hover and even fly backwards! Therefore, for our development of small, flapping, aircraft we can learn a lot from them.
One of the activities in my research group is to simulate air flow around flapping wings in order to better understand the performance of insect flight. Approximating the solution to the physical flow equations
with mathematical techniques, we can compute flight performance quantities, such as lift and drag. Since these are time and memory space intensive computations, efficiency is of utmost importance.
With the insights obtained from analyzing the flow solution of the simulation, we hope to contribute to the design of Delfly Micro - a tiny flapping micro air vehicle developed at the faculty of Aerospace Engineering of Delft University of Technology. Delfly Micro is the smallest in the Delfly series. While the original Delfly has a 20 cm wing span, Delfly Micro only has 5 cm wing span. Due to the small wings aerodynamic performance is very important.

Prof.dr.drs.ir. Hester Bijl is full professor Computational Aerodynamics at the Faculty of Aerospace Engineering of Delft University of Technology. She studied Applied Math in Delft, as well as English in Leiden. After her studies she decided to become a PhD-student in Delft, developing a new method for the computation of flows with both high and low speeds regions. After her PhD she worked a little less than two years as management consultant for The Boston Consulting Group. Since October 1999 she works at the Aerospace Engineering faculty in Delft, starting as assistant professor. In april 2006 she was appointed full professor - the first female professor at the Aerospace Engineering Faculty of the TU Delft. As department chair, Hester now is a member of the management team of the Faculty. She has a partner and two sons (6 and 7 years old).
Monday 12 January was the fourth edition of the Girl Geek Dinner at the Flexbar in Amsterdam. ~35 girl geeks and their male companions listened attently to AI Professor Frances Brazier as she shared real-life tales of her climb up the academic ladder.
Frances quoted statistics regarding women in academia (from the VHTO), and shared her battle-hardened point of view as an ’old garde’ female academic, with “tough love” advice for the younger generation. Her unabashedly candid and direct point of view raised a bit of controversy, resulting in heated and passionate discussion. At the end of her talk, Francis also spoke about her research, explaining a bit about autonomous systems and the AgentScape platform that she has developed in conjunction with the IIDS group at the Vrije Universiteit.
The next Girl Geek Dinner will be on Tuesday 21 April 2009 in the Flexbar. The speaker will be Hester Bijl, Professor of Aerospace Engineering at the Technical University of Delft. Keep an eye on our website for more information!
Abstract: Expectations — both our own and those of others — strongly influence our careers. Dealing with these expectations can be a challenge! Throughout my life and my academic career, I have encountered numerous choices, surprises, and life-lessons. Pain can be minimized by learning from others — so in this talk, I will share some of the lessons that I and my collegues have learned along the way …
