In order to decide on advertisement fees for web servers, Naor and Pinkas introduced (threshold) metering schemes secure against coalitions of corrupt servers and clients. Several researchers have generalized the idea of Naor and Pinkas: first metering scheme with pricing and dynamic multi-threshold metering schemes have been proposed; later the solution has been extended to allow general acces...

To control the traffic flows near on-ramps and off-ramps, ramp metering installations can be used. We compare on-ramp metering and off-ramp metering, with respect to queue forming and total time spent. Both control measures are used to improve traffic flow on freeways, and both have influence on the route choice of the drivers. Although the two measures are very similar, there are some major di...

During the last century, there has been considerable economic growth and development of cities around the world. The growth has led to an expansion of car-ownership and ultimately increased congestion of the road network. Traffic engineers and transport planners have attempted to mitigate the consequences of congestion of motorways and freeways using a number of techniques. One of which has bee...

The analysis and separation of audio signals into their original components is an important prerequisite to automatic transcription of music, extraction of metadata from audio data, and speaker separation in video conferencing. In this paper, a method for the separation of drum tracks from polyphonic music is proposed. It consists of an Independent Component Analysis and a subsequent partitioni...

We present an analysis of the bass drum circuit from the classic Roland TR-808 Rhythm Composer, based on physical models of the device’s many sub-circuits. A digital model based on this analysis (implemented in Cycling 74’s Gen ̃) retains the salient features of the original and allows accurate emulation of circuit-bent modifications—complicated behavior that is impossible to capture through bla...

Presented is a method of generating a full drum kit part for a provided kick-drum sequence. A sequence to sequence neural network model used in natural language translation was adopted to encode multiple musical styles and an online survey was developed to test different techniques for sampling the output of the softmax function. The strongest results were found using a sampling technique that ...

An analysis is made of the deflected forms assumed by an elastic strip when it is bent and stretched around a rigid drum. A summary is first given of the method of analysis used and the results obtained in a previous study where the drum width is equal to or greater than that of the strip. This work is then extended to the case where the strip width exceeds that of the drum. Defiected forms and...

Traditional drum machines and digital drum-kits offer users the ability to practice or perform with a supporting ensemble – such as a bass, guitar and piano – but rarely provide support in the form of an accompanying percussion part. Beatback is a system which develops upon this missing interaction through offering a MIDI enabled drum system which learns and plays in the user's style. In the co...

This documents presents an overview of current audio level and loudness measuring techniques and concepts, in the context of musical and post-production environments. It proposes a metering application, which is currently in early development, which should address metering needs currently unsatisfied in Linux.

This thesis investigates the moment, when the drumstick hits the membrane of a drum. Experiments were conducted to obtain information about the interaction of drummer, drumstick and membrane during a single stroke. Using a modified drumstick, the force on the drumstick, the acceleration of the stick’s tip, the duration of the contact between stick and membrane and the sound of the drum were rec...
