For the purpose of eliminating the troublesome mastoid cavity after tympanoplasty, some surgical procedures have been devised, which consist of preservation of the external ear canal, so that the operative mastoid cavity is primarily closed, with the use of fascia, periost or vein as a tympanic graft. Surgical procedures are as follows : At the first place, mastoidectomy is carried out without ...

This paper presents an unconventional approach for work-zone bottleneck traffic control through integrating the dynamic late merge with a merge metering via wireless communication at the downstream taper area of a work zone, termed as Dynamic Merge Metering Traffic Control System (DMM-Tracs). The architecture and communication system for the DMM-Tracs, including system components, communication...

Climate change, awareness of energy efficiency, new trends in electricity markets, the obsolescence of the actual electricity model, and the gradual conversion of consumers to prosumer profiles are the main agents of progressive change in electricity systems towards the Smart Grid paradigm. The introduction of multiple distributed generation and storage resources, with a strong involvement of r...

In order to decide on advertisement fees for web servers, Naor and Pinkas 7] introduced metering schemes. They proposed metering schemes in which any server is able to construct a proof to be sent to an audit agency if and only if it has been visited by at least a certain number, say h, of clients. Afterwards, the authors of 3] generalized the idea of Naor and Pinkas and proposed metering schem...

We apply model predictive control to optimally coordinate variable speed limits and ramp metering. The basic idea is that speed limits can increase the (density) range in which ramp metering is useful. For the prediction we use a slightly adapted version of the METANET traffic flow model that takes the variable speed limits into account. The optimal control signals aim at minimizing the total t...

 Ramp metering has been recognized as one of viable strategies of freeway traffic management, which may improve travel speed as well as reduce delay. In this study, a dynamic model is developed to optimize metering rates of a series of on-ramps which maximize the total throughput subject to vehicle density, roadway capacity, and queue length constraints with simultaneous perturbation stochasti...

Currently, Advanced Metering Infrastructure (AMI) systems have equipped the low voltage section with a communication system that is being used mainly for metering purposes, but it can be further employed for additional applications related to the Smart Grid (SG) concept. This paper explores the potential applications beyond metering of the available channel in a Power Line Communication-based A...

This paper aims at presenting our method to generate drum tracks to accompany guitar tracks. Our approach was to work on songs in the Midi format, separate them into several segments and then design our own features for the input guitar tracks as well as for the output drum tracks. We performed clustering algorithms (K-means, mixture of Gaussian, DBSCAN) as well as K-nn to group similar guitar ...

In this paper we present novel rhythm features derived from drum tracks extracted from polyphonic music and evaluate them in a genre classification task. Musical excerpts are analyzed using an optimized, partially fixed Non-Negative Matrix Factorization (NMF) method and beat histogram features are calculated on basis of the resulting activation functions for each one out of three drum tracks ex...

In order to train and test algorithms that can automatically detect drum events in polyphonic music, ground truth data is needed. This paper describes a setup used for gathering manual annotations for 49 real-world music fragments containing different drum event types. Apart from the drum events, the beat was also annotated. The annotators were experienced drummers or percussionists. This paper...
