Passive mobile data for studying seasonal tourism mobilities: an application in a Mediterranean Coastal destination
MDPI (2021-02-22)The article uses passive mobile data to analyse the complex mobilities that occur in a coastal region characterised by seasonal patterns of tourism activity. A large volume of data generated by mobile phone users has ... -
Percentage Points of a Test Statistic Useful in Manova with Structured Covariance Matrices
Nova Science Publishers (2013)The exact distribution of a test statistic ΛH for testing equality of mean vectors of m p-variate Gaussian populations having compound symmetry has been derived using inverse Mellin transform, calculus of residues and ... -
Perception of products by progressive multisensory integration: a study on hammers
Elsevier (2011-07)The aim of this work is to determine the influence of multisensory (visual-haptic) integration and the level of interaction (seeing photographs, seeing the actual product, touching it and using it) on the perception of ... -
Perimeter detection in sketched drawings of polyhedral shapes
The Eurographics Association (2017)This paper describes a new “envelope” approach for detecting object perimeters in line-drawings vectorised from sketches of polyhedral objects. Existing approaches for extracting contours from digital images are unsuitable ... -
Periodically Correlated Space-Time Autoregressive Hilbertian Processes
Atlantis Press (2021-06)In this paper, we introduce periodically correlated space-time autoregressive processes with values in Hilbert spaces. The existence conditions and the strong law of large numbers are established. Moreover, we present an ... -
Personalised code generation from large schema sets for geospatial mobile applications
Springer Vienna (2014-05)XML and XML Schema are used in the geospatial domain for the definition of standards that enhance the interoperability between producers and consumers of spatial data. The size and complexity of these geospatial standards ... -
Phase and amplitude reconstruction in single-pixel transmission microscopy: a comparison of Hadamard, cosine, and noiselet bases
Optical Society of America (2021-08-10)Hadamard, cosine, and noiselet bases are implemented into a digital holographic microscope based on single-pixel imaging with the capability to retrieve images of complex objects. The object is illuminated with coherent ... -
Phase imaging by spatial wavefront sampling
Optical Society of America (2018)Phase-imaging techniques extract the optical path length information of a scene, whereas wavefront sensors provide the shape of an optical wavefront. Since these two applications have different technical requirements, ... -
Photon Counting 3-D Object Recognition Using Digital Holography
Institute of Electrical and Electronics Engineers (IEEE) (2013)We present an analysis of the recognition performance of 3-D objects reconstructed from digital holograms recorded under photon counting conditions. The digital holograms are computed by applying four-step phase-shifting ... -
PiCoCo: Pixelwise Contrast and Consistency Learning for Semisupervised Building Footprint Segmentation
IEEE (2021-10-11)Building footprint segmentation from high-resolution remote sensing (RS) images plays a vital role in urban planning, disaster response, and population density estimation. Convolutional neural networks (CNNs) have been ... -
Pinpointing spatio-temporal interactions in wildfire patterns
Springer-Verlag (2012-12)The spatial and spatio-temporal patterns of wildfire incidence and their relationship to various geographical and environmental variables are analyzed. Such relationships may be treated as components in particular point ... -
Place and city: Operationalizing sense of place and social capital in the urban context
John Wiley & Sons Ltd (2017)The academic interest in social concepts in city contexts, such as sense of place and social capital, has been growing in the last decades. We present a systematic literature review that confirms the strong relationship between ... -
Place and City: Toward Urban Intelligence
MDPI (2018-08)Place, as a concept, is subject to a lively, ongoing discussion involving different disciplines. However, most of these discussions approach the issue without a geographic perspective, which is the natural habitat of a ... -
Placement of Social Digital Twins at the Edge for Beyond 5G IoT Networks
IEEE (2022-07-22)As the fifth-generation (5G) and beyond (5G+/6G) networks move forward, and a wide variety of new advanced Internet of Things (IoT) applications are offered, effective methodologies for discovering time-relevant ... -
Point Patterns Occurring on Complex Structures in Space and Space-Time: An Alternative Network Approach
Taylor & Francis (2017-10)This article presents an alternative approach of analyzing possibly multitype point patterns in space and space–time that occur on network structures, and it introduces several different graph-related intensity measures. ... -
Prácticas artísticas en la época del dataceno. Data Biography: rastros digitales para la exploración biográfica de la identidad personal
Universitat Oberta de Catalunya (2019)Cada vez más detalles de nuestra vida son registrados y almacenados para formar parte de lo que ha venido a llamarse big data. Nuestra vida, en todos sus aspectos, deja un rastro digital que se actualiza continuamente ... -
Prediction of spatial functional random processes: comparing functional and spatio-temporal kriging approaches
Springer Berlin Heidelberg (2019)We present and compare functional and spatio-temporal (Sp.T.) kriging approaches to predict spatial functional randomprocesses (which can also be viewed as Sp.T. random processes). Comparisons with respect to computational ... -

Prior-based probabilistic latent semantic analysis for multimedia retrieval
Springer Verlag (2017)Topic models have shown to be one of the most effective tools in Content-Based Multimedia Retrieval (CBMR). However, the high computational learning cost together with the huge expansion of multimedia collections limit ... -
Procedural modeling of plant ecosystems maximizing vegetation cover
Springer (2022-03-02)Vegetation plays a major role in the realistic display of outdoor scenes. However, manual plant placement can be tedious. For this reason this paper presents a new proposal in the field of procedural modeling of natural ...
