Reducing start and stop time without destroying the pavement surface is important in enhancing productivity of double-drum roller and compact quality of asphalt pavement, but it is difficult in confirming the maximum brake deceleration or start acceleration of double-drum roller. Dynamic analysis is used in studying these questions, and a mathematic model of double-drum roller is established, b...

During the composition of a piece of music, composers often focus on the crafting of melody and harmonic lines rather than a percussive track that may accompany them. For amateur composers, creating a drum track by hand can be both tedious and frustrating, due to their lack of skill and experience with the task. In recent years, computer software tools have been created to help automate the cre...

Metering technology is one of the core technologies of the smart power grid. The overall metering solution and related products have a wide market space in the whole process of power production, which bring new opportunities for power distribution development from automation to intelligentialize, and provide technical supports for the power metering system platform. Because of the importance of...

A key issue for the success of a smart grid is the capability to accommodate efficient smart metering. Following the trend towards timely monitoring of energy consumption and production via Internet related technologies and in-network metering platforms, we need to investigate performance-related aspects of smart metering and how they affect the overall operation. We present here our experience...

More and more metering schemes based on some special protocols or mechanisms are used to calculate the number of visits which a website receives in a certain time frame. Then, the amount of money that an advertiser pay to a website depends on this number of visits. Until now, many protocols were suggested for metering schemes in literature. However, the discussion mainly focused on the theory o...

This study measured surface electromyography of the biceps brachii and triceps brachii during repeated drum playing with and without a drumstick to better understand activation of the upper arm muscles and inform the use of instrument playing for motor rehabilitation. A total of 40 healthy college students participated in this study. All participants were asked to strike a drum with their hand ...

A percussionist can alter the harmonic content of a tunable acoustic drum to provide a desired sound. By analysis of different aspects in construction of a drum the specific sound can be implemented. Through a Fast Fourier Transform of electronically acquired audio data an analysis of a drum can be performed at many stages of its construction. By dissecting the drum construction into various la...

Critics of current tying doctrine argue that metering ties can increase consumer welfare and total welfare without increasing output and that they generally increase both welfare measures. Contrary to those claims, we prove that metering ties always lower both consumer welfare and total welfare unless they increase capital good output. We further show that under market conditions we argue are r...

Techniques for Machine Understanding of Live Drum Performances by Eric Dean Battenberg Doctor of Philosophy in Engineering Electrical Engineering and Computer Sciences University of California, Berkeley Professor Nelson Morgan, Chair This dissertation covers machine listening techniques for the automated realtime analysis of live drum performances. Onset detection, drum detection, beat tracking...

The drum machine has been an important tool in music production for decades. However, its flawless way of playing drum patterns is often perceived as mechanical and rigid, far from the groove provided by a human drummer. This paper presents research towards enhancing the drum machine with learning capabilities. The drum machine learns user-specific variations (i.e. the groove) from human drumme...
