Evers, L.G. (author), Assink, J. D. (author), Smets, P.S.M. (author)Supersonic rockets generate low-frequency acoustic waves, that is, infrasound, during the launch and re-entry. Infrasound is routinely observed at infrasound arrays from the International Monitoring System, in place for the verification of the Comprehensive Nuclear-Test-Ban Treaty. Association and source identification are key elements of the...journal article 2018

Toodesh, R. (author), Verhagen, S. (author)The spatial sampling often used to process and represent bathymetric data are of fixed grid resolution where the least depth value is stored in each grid cell. This results in Digital Elevation Models (DEMs) that are used to depict the underlying features of the seafloor. With the discretion of the user, the resulting DEMs used may either be...journal article 2018

Yang, M. (author), Yang, Tianliang (author), Zhang, L. (author), Lin, Jinxin (author), Qin, Xiaoqiong (author), Liao, Mingsheng (author)Large-scale reclamation projects during the past decades have been recognized as one of the driving factors behind land subsidence in coastal areas. However, the pattern of temporal evolution in reclamation settlements has rarely been analyzed. In this work, we study the spatio-temporal evolution pattern of Linggang New City (LNC) in Shanghai...journal article 2018

Yan, Gaowei (author), Jia, Songda (author), Ding, Jie (author), Xu, Xinying (author), Pang, Y. (author)In this paper, a local cloud model similarity measurement (CMSM) is proposed as a novel method to measure the similarity of time series. Time series similarity measurement is an indispensable part for improving the efficiency and accuracy of prediction. The randomness and uncertainty of series data are critical problems in the processing of...journal article 2018

Sherafatipour, S. (author), Saffarzadeh, Mahmoud (author), Tavasszy, Lorant (author), Fatemi Ardestani, S. Farshad (author)The extended gate concept aims to reduce the pressure on international ports by postponing administrative processes from these border gates to inland terminals. At present, this approach is used mainly in the container transport industry in European and Asian ports. In this paper we study an extended gate concept, where inland customs services...journal article 2018

Pei, W. (author), Dibeklioglu, H. (author), Tax, D.M.J. (author), van der Maaten, L.J.P. (author)We present a new model for multivariate time-series classification, called the hidden-unit logistic model (HULM), that uses binary stochastic hidden units to model latent structure in the data. The hidden units are connected in a chain structure that models temporal dependencies in the data. Compared with the prior models for time-series...journal article 2018

Khuntia, S.R. (author), Rueda, José L. (author), van der Meijden, M.A.M.M. (author)Long-term electricity load forecasting plays a vital role for utilities and planners in terms of grid development and expansion planning. An overestimate of long-term electricity load will result in substantial wasted investment on the construction of excess power facilities, while an underestimate of the future load will result in...journal article 2018

Reappraisal as a coping strategy might help first<br/>responders to better cope with their emotional responses to traumatic events.<br/>Objective: This study investigated the effects of repeated sessions of a...journal article 2017

van der Spek, J.E. (author), Bakker, M. (author)The influence of the length of the calibration period and observation frequency on the predictive uncertainty in time series modeling of groundwater dynamics is investigated. Studied series are from deltaic regions with predominantly shallow groundwater tables in a temperate maritime climate where heads vary due to precipitation and...journal article 2017

Amiri Simkooei, A. (author), Mohammadloo, Tannaz H. (author), Argus, D.F. (author)The second reprocessing of all GPS data gathered by the Analysis Centers of IGS was conducted in late 2013 using the latest models and methodologies. Improved models of antenna phase center variations and solar radiation pressure in JPL’s reanalysis are expected to significantly reduce errors. In an earlier work, JPL estimates of position time...journal article 2017

Leontaris, G. (author), Morales Napoles, O. (author), Wolfert, A.R.M. (author)There are numerous uncertainties that impact offshore operations. However, environmental uncertainties concerning variables such as wave height and wind speed are crucial because these may affect installation and maintenance operations with potential delays and financial consequences. In order to include these uncertainties into the duration...journal article 2016

Nemati, M. (author), Kenjeres, S. (author), Urbach, Paul (author), Bhattacharya, N. (author)The scattering of coherent light from a system with underlying flow can be used to yield essential information about dynamics of the process. In the case of pulsatile flow, there is a rapid change in the properties of the speckle images. This can be studied using the standard laser speckle contrast and also the fractality of images. In this...journal article 2016

Velsink, H. (author)Adjustment and testing of a combination of stochastic and nonstochastic observations is applied to the deformation analysis of a time series of 3D coordinates. Nonstochastic observations are constant values that are treated as if they were observations. They are used to formulate constraints on the unknown parameters of the adjustment problem...journal article 2016

Obergfell, C.C.A. (author), Bakker, M. (author), Maas, Kees (author)The flood-wave method is implemented within the framework of time-series analysis to estimate aquifer parameters for use in a groundwater model. The resulting extended flood-wave method is applicable to situations where groundwater fluctuations are affected significantly by time-varying precipitation and evaporation. Response functions for time...journal article 2016

Shang, H. (author), Li, J. (author), Menenti, M. (author)The soil wetness condition is a useful indicator of inundation hazard in floodplains, such as the Poyang Lake floodplain. Special Sensor Microwave Imager (SSM/I) passive microwave data were used to monitor water-saturated soil and open water areas of the Poyang Lake floodplain from 2001 to 2008, capturing the inundation patterns of this area in...journal article 2015

Khodabandeh, A. (author), Amiri-Simkooei, A.R. (author), Sharifi, M.A. (author)The efficacy of robust M-estimators is a well-known issue when dealing with observational blunders. When the number of observations is considerably large—long time series for instance—one can take advantage of the asymptotic normality of the M-estimation and compute reasonable estimates for the unknown parameters of interest. A few leading M...journal article 2011

Veling, E.J.M. (author), Maas, C. (author)In this paper we comment on some recent numerical and analytical work to evaluate the Hantush Well Function. We correct an expression found in a Comment by Nadarajah (J. of Hydrology, vol. 338, p. 152-153 (2007)) to a paper by Prodanoff et al. (J. of Hydrology, vol. 318, p. 173-183 (2006)). We subsequently derived another analytic representation...journal article 2010

Blaas, J. (author), Botha, C.P. (author), Grundy, E. (author), Jones, M.W. (author), Laramee, R.S. (author), Post, F.H. (author)In this paper, we present a new visual way of exploring state sequences in large observational time-series. A key advantage of our method is that it can directly visualize higher-order state transitions. A standard first order state transition is a sequence of two states that are linked by a transition. A higher-order state transition is a...journal article 2009

Broersen, P.M.T. (author)The sample autocorrelation function is defined by the mean lagged products (LPs) of random observations. It is the inverse Fourier transform of the raw periodogram. Both contain the same information, and the quality of the full-length sample autocorrelation to represent random data is as poor as that of a raw periodogram. The autoregressive (AR)...journal article 2009

Broersen, P.M.T. (author)Vector time series analysis takes the same model order and model type for the different signals involved. Selection criteria have been developed to select the best order to simultaneously predict the different components of the vector. The prediction of single channels might require a different order or type for the best accuracy of each...journal article 2009
