Mathematical Modelling of a flute

The transverse flute can be studied on many aspects. In this thesis the sound waves that can be generated inside the flute are studied on their shape and frequencies. To achieve this, two mathematical models of the sound waves inside a flute are developed. To develop these models, solutions to the second dimensional wave equation are calculated...

Trait Analysis to Facilitate Children’s Books Recommender Systems: Extracting perspective and sentiment traits from book fulltext and descriptions

Recommender systems are a useful tool for match- ing readers with books. However, the lack of user data from children, both due to privacy concerns as well as a low incentive to leave reviews, results in existing systems proving inadequate at recom- mending to the youth. It has been shown that chil- dren have a different relation regarding...

Bepalen van het massatraagheidsmoment met behulp van een bifilar pendulum: Determining the moments of inertia using a bifilar pendulum

The aim of this thesis is to investigate the use of a bifilar pendulum for determining the moments of inertia of the TU Delft solar boat and to quantitatively predict the estimates. In the first part, several methods are discussed which can be applied in deriving the equations of motion of the pendulum. A new method, Kane's method, will be...

Conceptual Modeling of Probabilistic Treatment Planning to deal with Microscopic Disease in Radiotherapy

A visible tumor can be surrounded by invisible groups of cancer cells called microscopic disease that cannot be imaged. For ultimate tumor control it is imperative that not only the visible tumor, but also this microscopic disease is irradiated. In current clinical practice, microscopic disease control is achieved by not just irradiating the...
