Assessment of Misspecification in CDMs Using a Generalized Information Matrix Test
If the probability model is correctly specified, then we can estimate the covariance matrix of the asymptotic maximum likelihood estimate distribution using either the first or second derivatives of the likeli...

The Interactive Megalopolis: A New Approach in Evaluating the Economic Benefits of High-Speed Ground Transportation Linkages
Ever since the emergence of High-Speed Ground Transportation (HSGT) in Japan and later, in Europe, the rationalization has focused on congestion relief requiring promoters to rely on modal diversions from avia...

MAP Estimation Using a Possibly Misspecified Parameter Redundant Model
In this paper, new theorems are proved which show how in some cases the asymptotic distribution of Maximum A Posteriori (MAP) estimates can be obtained for parameter redundant probability models which are poss...

A Comparison of Some Gradient Threshold Estimators for the Nonlinear Diffusion of Perona-Malik. A Novel Proposal to Improve Edges Detection in Mammography Images
In this work, based on the nonlinear Perona-Malik anisotropic diffusion (AD) model, we develop an efficient smoothing algorithm for mammography images that preserves edges and provides valuable information for...

High-Resolution Imaging Mass Spectrometry of Human Donor Eye: Photoreceptors Cells and Basal Laminar Deposit of Age-Related Macular Degeneration
Pathologies of the retina are clinically visualized in vivo with OCT and ex vivo with immunohistochemistry. Although both techniques provide valuable information on prognosis and disease state, a comprehensive...

Regularized Robust Confidence Interval Estimation in Cognitive Diagnostic Models
Although prior work has investigated the effects of model misspecification on inference in Cognitive Diagnostic Models (CDMs) (e.g., Liu et al., Multivar Behav Res, 1–20, 2021), few studies have explored how r...

Reasoning over Test Specifications Using Assume-Guarantee Contracts
We establish a framework to reason about test campaigns described formally. First, we introduce the notion of a test structure—an object that carries i) the formal specifications of the system under test, and ...

Collaborative Control of Mobile Manipulator Robots Through the Hardware-in-the-Loop Technique
This article aims at designing and implementing the “Hardware-in-the-Loop” (HIL) technique, to evaluate the collaborative control algorithm of two mobile manipulator robots to carry out tasks of movement and m...

Towards Better Test Coverage: Merging Unit Tests for Autonomous Systems \(^{\dagger }\)
We present a framework for merging unit tests for autonomous systems. Typically, it is intractable to test an autonomous system for every scenario in its operating environment. The question of whether it is po...

Simulation Studies of Item Bias Estimation Accuracy
The item-parameter invariance assumption of Cognitive Diagnostic Models (CDMs) states that item parameters are not functionally dependent upon the characteristics of an examinee with respect to a specific exam...

Thermal Analysis of an Earth Energy Bank
Buildings account for about 40% of the overall energy demand in the EU, and low grade thermal energy, for space heating and domestic hot water, is a significant percentage of this demand (Bertrand et al. in Ap...

ARIMAX Modelling of Ron97 Price with Crude Oil Price as an Exogenous Variable in Malaysian
Malaysia’s pricing policy has shuffled between Automatic Adjusted Formula (APM) and Managed Float System (MFS). One major problem in forecasting fuel prices is the use of the structural model. The model uses...
