In order to explore the possibility of a timbre-based rhythm theory, a drum pattern classification system was developed, which is capable of describing the internal structure of a drum groove in a stochastic way. Using an onset detection algorithm, timbral features were extracted at every drum onset of the sample file. Next, a Hidden Markov Model (HMM) was fitted to the data. Local decoding of ...

This paper treats the problem of controlling large freeway systems through ramp metering to enhance their efficiency. Following a rigorous discretization methodology, an extension of the CTM model to inhomogeneous freeways with on and off ramps is proposed. Based on passivity theory and the piecewise affine formulation of this model, an LMI formulation is developed to design non-local feedback ...

Objective: In recent years, farmers have shown great interest to using native drill planter rather than complex planters to grow vegetables. Methods: In this study, we tested a native planter Independent variables were the two types of substrate surface (asphalt and plowed field), three ground speed (3, 5 and 7 kph) and four types of seeds (tomatoes, onions, radishes and lettuce). Dependent var...

We used speckle visibility spectroscopy to measure the time-resolved dynamcis of avalanching down the inclined surface of a granular material in a half-full rotating drum operating in the slumping regime. The distribution of the avalanche period, t(d), rest time between them, t(r), and peak particle velocity fluctuation, δv(p)(2), are all normally distributed. While the distributions of the two...

The purpose of this report is to provide utilities implementing Advanced Metering Infrastructure (AMI) with the knowledge necessary to secure that implementation appropriately. We intend that utilities use this report to guide their planning, procurement, roll-out, and assessment of the security of Advanced Metering Infrastructure. This report discusses threats to the AMI, the likely sources of...

Unlimited access to a motorway network can, in overloaded conditions, cause a loss of capacity. Ramp metering (signals on slip roads to control access to the motorway) can help avoid this loss of capacity. The design of ramp metering strategies has several features in common with the design of access control mechanisms in communication networks. Inspired by models and rate control mechanisms de...

The onramp metering control problem is posed using a cell transmission-like model called the asymmetric cell transmission model (ACTM). The problem formulation captures both freeflow and congested conditions, and includes upper bounds on the metering rates and on the onramp queue lengths. It is shown that a near-global solution to the resulting nonlinear optimization problem can be found by sol...

-Industrial wireless communication opens up many new possibilities for highly flexible and efficient solutions. In this paper use of GSM network is for energy metering system incorporating the widely used GSM network. In many countries GSM network is popular because of its vast coverage area & cost effectiveness. Using GSM as the medium for metering system provides a cheap, wireless, seamlessly...

Advanced metering infrastructure provides the first building block in smart grids by empowering customers and utilities with real-time information regarding energy use. It is a key element in the U.S. government’s push for electric grid modernization. Using a panel dataset for 50 U.S. states and the District of Columbia over the years 2007–2012, we evaluate the impacts of a polycentric governan...

While Prior Subspace Analysis (PSA) has proved an effective tool for transcribing mixtures of snare, kick drum and hi-hat both in the “drums-only” case and in the presence of pitched instruments attempts to extend it to deal with increased numbers of drum types have met with mixed results. To overcome this an automatic modeling and grouping procedure has been developed which groups drum events ...
