A Simultaneous Estimation of the Baseline Intensity and Parameters for Modulated Renewal Processes

open access: yesAxioms, 2022
This paper proposes a semiparametric solution to estimate the intensity (hazard) function of modulated renewal processes: a nonparametric estimate for the baseline intensity function together with a parametric estimate of the model parameters of the ...

Navigation on a Poisson point process

open access: yes, 2008
On a locally finite point set, a navigation defines a path through the point set from one point to another. The set of paths leading to a given point defines a tree known as the navigation tree.

Upper bounds for spatial point process approximations [PDF]

open access: yes, 2005
We consider the behavior of spatial point processes when subjected to a class of linear transformations indexed by a variable T. It was shown in Ellis [Adv. in Appl. Probab.

Point-Map-Probabilities of a Point Process and Mecke's Invariant Measure Equation

open access: yes, 2016
A compatible point-shift $F$ maps, in a translation invariant way, each point of a stationary point process $\Phi$ to some point of $\Phi$. It is fully determined by its associated point-map, $f$, which gives the image of the origin by $F$. It was proved

Distinguishing Synchronous and Time Varying Synergies using Point Process Interval Statistics: Motor Primitives in Frog and Rat.

open access: yesFrontiers in Computational Neuroscience, 2013
We present and apply a method that uses point process statistics to discriminate the forms of synergies in motor pattern data, prior to explicit synergy extraction. The method uses electromyogram (EMG) pulse peak timing or onset timing.

Cox Processes Associated with Spatial Copula Observed through Stratified Sampling

open access: yesMathematics, 2021
Cox processes, also called doubly stochastic Poisson processes, are used for describing phenomena for which overdispersion exists, as well as Poisson properties conditional on environmental effects.

Video Sensor-Based Complex Scene Analysis with Granger Causality

open access: yesSensors, 2013
In this report, we propose a novel framework to explore the activity interactions and temporal dependencies between activities in complex video surveillance scenes.

Shearer's point process, the hard-sphere model and a continuum Lov\'asz Local Lemma [PDF]

open access: yes, 2017
A point process is R-dependent, if it behaves independently beyond the minimum distance R. This work investigates uniform positive lower bounds on the avoidance functions of R-dependent simple point processes with a common intensity.

Additive friction stir deposition vs. friction surfacing: Comparison of friction stir-based approaches for groove repair of high strength aluminum alloys

open access: yesMaterials & Design
Friction stir-based solid-state layer deposition techniques show considerable potential as additive manufacturing approach but also for repair applications.

Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.
