Availle mostly records books, but every now and then, something else pops up. For example, she has recorded names of streets in Germany to be made into a synthetic voice for a navigation system. She recorded telephone menus (and hopes they didn’t turn out too annoying in the end). She has also recorded a large variety of university-level textbooks for a Canadian publisher, ranging from topics on psychology, business and law, and writing. Availle would do (almost) anything to support science and help spreading the word of reason. Thus, among her favourite projects are narrations for scientific videos. Some of them can be found below.

Coordinating the motion for a large set of object is an important problem that occurs in many different applications. Even when all involved particles pursue the same overall objective, there may be limitations on individual energy supply or motion control. One approach to dealing with this difficulty is to use an exterior, uniform global force. However, when all objects in an arrangement get the same input signal, how can we rearrange their relative position? We can break the resulting symmetry by making use of different interaction with a boundary.

Covering objects with other objects have various applications in real life. For example, how many circular sprinklers need to be installed on a rectangular lawn so that the whole lawn can be watered, while at the same time using as little water as possible? This problem can be solved optimally if the skew of the rectangle is taken into account.

Building large structure like the international space station in Earth's orbit is a massive undertaking. Instead of training skilled astronauts for the task, simple robots can be used. These robots that can perform very simple tasks, can use modern lightweight materials to produce the basic framework of space stations or human habitats. Furthermore, if the robots themselves are very simple, they can themselves be mass-produced in space.

We motivate and visualize problems and methods for packing a set of objects into a given container, in particular a set of non-uniform circles or squares into a square or circular container. Questions of this type have attracted a considerable amount of attention and are known to be notoriously hard. We focus on a particularly simple criterion for deciding whether a set can be packed: comparing the total area of all objects to the area of the container.

We motivate, visualize and demonstrate recent work for minimizing the total execution time of a coordinated, parallel motion plan for a swarm of N robots in the absence of obstacles. Under relatively mild assumptions on the separability of robots, the algorithm achieves constant stretch.

Zika is a disease transmitted by mosquitos. In an attempt to eradicate zika, it is necessary to kill enough (infected) mosquitos. This is an approach using a drone with attached electrical grid that flies on a given path through mosquite swarms. The video below deals with the problem of computing an efficient path with as few turns as possible.

I know, the application sounds highly contrived - but that’s really how it’s done!

In this video, IRMA the robot is tasked to move around and scan its environment to produce three dimensional images. Since the scanning process is very time consuming, the goal is to find a minimal number of scan positions that, when taken together, provide a full view of the environment. For this, an intricate linear programming approach, that switches between the primal and dual problems, is presented.

This video shows how swarms of inexpensive robots can be employed to efficiently explore an unknown area. Two different algorithms are explained and analysed; the first algorithm uses an infinite robot supply (clearly a theoretical setting). The second algorithm explains a heuristic for the more realistic case of a limited amount of robots exploring the area. All that theory is topped off with scenes of little, cute, and real robots executing the second algorithm.

This art project sets out to create a fictional language called Hyphenic, and present it as authentic. Consisting of an audiobook and a film, the writing system and its entire alleged cultural and historical backdrop will be put forward. The book aims to organise this mysterious language in a coherent syntax. However, it is the contradicting theories associated with the origin of the language that remain the focal point. The completed project that was exhibited at Moderna Museet in Stockholm in October 2018.

Most of Availle's recordings are in the public domain and thus can be used freely and for all purposes - no extra permission needed. If you do use Availle's recordings, it would be nice to drop her a line or two though - she's always interested in hearing of such things! Below is one example of a derivative of Availle's recordings.

Joonas Kreen is a musician from Estonia. He plays a number of instruments and offers meditative music with soft melodies and roots in lounge-jazz. In his piece **Takeoff** from his first album **My Luvly Hammock**, he included a short sequence of Availle's solo recording The Early History of the Airplane.

Have a listen to a very short sample (00:24) of **Takeoff** featuring Availle:

Actually, the whole album is great, just what you need after too long a day in the office! Since his first album, Joonas has created more music, check it out on his homepage: www.joonaskreen.com
