the mathematical modeling of fracture networks is critical for the exploration and development ofnatural resources. fractures can help the production of petroleum, water, and geothermal energy. theyalso greatly influence the drainage and production of methane gas from coal beds. orientation andspatial distribution of fractures in rocks are important factors in controlling fluid flow. the object...

The symbolic genre classification algorithm submited to the MIREX (Music Information Retrieval Exchange) 2005 is described here. Our algorithm uses a combination of k-nearest neighbors and Bayesian classifiers trained with different sets of statistical descriptors extracted from melody tracks extracted from MIDI files. It is aimed at classifying melodies by genre. The statistical descriptors de...

Obtaining accurate melodic contours from polyphonic music is essential to several music-informationretrieval (MIR) applications and is also useful from a musicological perspective. The presence of tabla and tanpura accompaniment in north Indian classical vocal performances, however, degrades the performance of common pitch detection algorithms (PDAs) that are known to provide accurate results w...

the concept of intelligently controlling the search process of gravitational search algorithm (gsa) is introduced to develop a novel data mining technique. the proposed method is called fuzzy gsa miner (fgsa-miner). at first a fuzzy controller is designed for adaptively controlling the gravitational coefficient and the number of effective objects, as two important parameters which play major ro...

We present a method for melody detection in polyphonic musical signals based on a model of the human auditory system. First, a set of pitch candidates is obtained for each frame, based on the output of an ear model and periodicity detection using correlograms. Trajectories of the most salient pitches are then constructed. Next, note candidates are obtained by trajectory segmentation (in terms o...

We present a query-by-humming music recognition system to retrieve a melody from a database of MIDI music. The hummed melody input is converted to a sequence of notes by a pitch estimation frontend so that the recognition task can be formulated as an error-tolerant string matching problem. The music notation used shows tempo and tone height invariance. Errors due to missing, additional or modif...

We introduce MedleyDB: a dataset of annotated, royaltyfree multitrack recordings. The dataset was primarily developed to support research on melody extraction, addressing important shortcomings of existing collections. For each song we provide melody f0 annotations as well as instrument activations for evaluating automatic instrument recognition. The dataset is also useful for research on tasks...

In this paper, we present a JXTA-based system for contents-based music information retrieval. The system finds matching melodies from a set of XML documents that encode music contents. The XML documents are stored in a native XML database and XPath query language is used to extract the information about the structure of music data. The matching algorithm utilizes the geometric hashing technique...

one of methods of improvement of the material flow is cross docking that in is considered as a good method to reduce inventory and improve customer satisfaction. too, the vehicle routing problem is one of the important problems in distribution management and its goal is to find paths for delivering various cargos. therefore, this study was conducted in order to vehicle routing problem with cros...
