A simulation study of a parametric mixture model of three different distributions to analyze heterogeneous survival data [PDF]

open access: yes, 2013
In this paper a simulation study of a parametric mixture model of three different distributions is considered to model heterogeneous survival data.Some properties of the proposed parametric mixture of Exponential, Gamma and Weibull are investigated.The ...

Parametric transfer in a synchronously pumped optical parametric oscillator [PDF]

open access: yes, 2006
The conditions for high fidelity parametric transfer of the pulse shape of a near-infrared pump pulse to a mid-infrared idler pulse of a synchronously pumped optical parametric oscillator are investigated theoretically and ...

Evaluation of Three Parametric Models for Estimating Directional Thermal Radiation from Simulation, Airborne, and Satellite Data

open access: yesRemote Sensing, 2018
An appropriate model to correct thermal radiation anisotropy is important for the wide applications of land surface temperature (LST). This paper evaluated the performance of three published directional thermal radiation models—the Roujean–Lagouarde (RL)

Development of an Adaptive Trajectory Tracking Control of Wheeled Mobile Robot

open access: yesRevista Facultad de Ingeniería, 2021
Classical modeling and control methods applied to differential locomotion mobile robots generate mathematical equations that approximate the dynamics of the system and work relatively well when the system is linear in a specific range. However, they may

Action classification using a discriminative non-parametric hidden Markov model [PDF]

open access: yes, 2013
We classify human actions occurring in videos, using the skeletal joint positions extracted from a depth image sequence as features. Each action class is represented by a non-parametric Hidden Markov Model (NP-HMM) and the model parameters are learnt in ...

Computationally Efficient Force and Moment Models for Propellers in UAV Forward Flight Applications

open access: yesDrones, 2019
Two low-order, parametric models are developed for the forces and moments that a rotating propeller undergoes in forward flight. The models are derived using a first-principles-based approach, and are computationally efficient in the sense of being ...

Semi-automated stereoradiographic upper limb 3D reconstructions using a combined parametric and statistical model: a preliminary study [PDF]

open access: yes, 2011
PURPOSE: Quantitative assessment of 3D clinical indices may be crucial for elbow surgery planning. 3D parametric modeling from bi-planar radiographs was successfully proposed for spine and lower limb clinical investigation as an alternative for CT-scan ...
