(Springer, 2017)In this work, new strategies for automatic identification of P- and S-wave arrival times from digital recorded local seismograms are proposed and analyzed. The database of arrival times previously identified by a human ...
-
(Elsevier, 2016)In this paper we propose an automatic volcano event detection system based on Hidden Markov Model (HMM) with state and event duration models. Since different volcanic events have different durations, therefore the state ...
-
(MDPI, 2022)This paper describes a system for the automatic determination of rock-breaking target poses for impact hammers used in underground mines. The rock-breaking target pose is defined as the position and angle at which the ...
-
(ELSEVIER, 2010)In this paper the nature and relevance of the information provided by intonation is discussed in the framework of second language learning. As a consequence, an automatic intonation assessment system for second language ...
-
(ELSEVIER, 2010)A numerical method for 2D LEFM crack propagation simulation is presented. This uses a Lepp–Delaunay based mesh refinement algorithm for triangular meshes which allows both the generation of the initial mesh and the local ...
-
(2012-12-18)In this article we present an automatic on-line color calibration system that makes extensive use of the spatial relationships between color classes in the color space. First, we introduce the definition of class-relative color ...

Automatic space object detection on all-sky images from a synoptic survey synthetic telescope array (Elsevier, 2020)Detection, classification, and characterization of Space Objects (SOs) are important tasks in many areas of research. Detection of SOs is important in predicting collisions with debris that could become hazards for satellites ...
-
(Taylor & Francis, 2015)Even though block caving mining method is already the most economical underground mining method for large massive ore bodies, it requires further technical advancements to also become a practical method for deep deposits ...
-
(2007)Many surveys have attempted to convey and synthesize the information of hundreds of studies on automobile fuel demand. In most cases, the focus has been placed in giving assessments of the most likely values of various ...
-
(MDPI, 2021)This paper describes an autonomous loading system for load-haul-dump (LHD) machines used in underground mining. The loading of fragmented rocks from draw points is a complex task due to many factors including: bucket-rock ...
-
(ELSEVIER SCIENCE BV, 2005-05-01)For any conforming mesh, the application of a skeleton-regular partition over each element in the mesh, produces a conforming mesh such that all the topological elements of the same dimension are subdivided into the same ...
-
(2009)Consider a system composed of n sensors operating in synchronous rounds. In each round an input vector of sensor readings x is produced, where the i-th entry of x is a binary value produced by the i-th sensor. The ...
-
(ELSEVIER, 2004-08-16)We show that the average number of characters examined to search for r random patterns of length m in a text of length n over a uniformly distributed alphabet of size a cannot be less than Omega(n log(sigma)(rm)/m). When ...
-
(John Wiley & Sons, 2014)Defining and formalizing the software development process is a common means for improving it. Software processmodeling is often a challenging and expensive endeavor, because a well specified processmay still include in ...
-
(MDPI AG, 2019)Avocado oil has generated growing interest among consumers due to its nutritional and technological characteristics, which is evidenced by an increase in the number of scientific articles that have been published on it. ...
-
(American Physical Society, 2017)Because of their quantum fluctuations, axion fields had a chance to experience field excursions traversing many minima of their potentials during inflation. We study this situation by analyzing the dynamics of an axion ...
-
(Elsevier, 2012-10-22)Incremental equilibrium equations and corresponding boundary conditions for an isotropic, hyperelastic and incompressible material are summarized and then specialized to a form suitable for the analysis of a spherical shell ...
-
Aysen seismic swarm (January 2007) in southern Chile: analysis using Joint Hypocenter Determination (SPRINGER, 2010-10)A seismic swarm at the Aysén fjord started in January, 2007, reaching its highest activity between January and April, 2007. It was punctuated by the Mw5.3 23rd January event and the Mw6.2 21st April event which triggered ...
-
(EDP Sciences, 2016)Context. Debris disks off er valuable insights into the latest stages of circumstellar disk evolution, and can possibly help us to trace the outcomes of planetary formation processes. In the age range 10 to 100 Myr, most ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2004-07)Azorella cyptantha yielded the diterpenes, azorellolide and the dihydroderivative, dihydroazorellolide, together with the known yaretol and 1alpha,10beta,4beta,5alpha-diepoxy-7alpha-germacran-6beta-ol. Both possess a carbon ...
