Robot Excitation Trajectories for Dynamic Parameter Estimation using Optimized B-Splines [PDF]

, 2012
In this paper we adressed the problem of finding exciting trajectories for the identification of manipulator link inertia parameters. This can be formulated as a constraint nonlinear optimization problem.

About one discrete analog of Hausdorff semi-continuity of suitable mapping in a vector combinatorial problem with a parametric principle of optimality ("from Slater to lexicographic")

Journal of Numerical Analysis and Approximation Theory, 2006
multicriteria linear combinatorial problem is considered, principle of optimality of which is defined by a partitioning of partial criteria onto groups with Slater preference relation within each group and the lexicographic preference relation ...

Negatively Invariant Sets and Entire Trajectories of Set-Valued Dynamical Systems [PDF]

Set-Valued and Variational Analysis, 2009
Strongly negatively invariant compact sets of set-valued autonomous and nonautonomous dynamical systems on a complete metric space, the latter formulated in terms of processes, are shown to contain a weakly positively invariant family and hence entire solutions.

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Childbearing Trajectories in a West African Setting: A Sequence Analysis Approach

Demography, 2023
AbstractThe lagging fertility transition in West Africa has important repercussions for global population growth but remains poorly understood. Inspired by Caldwell and colleagues' fertility transition framework, as well as by subsequent research, we examine diversity in women's holistic childbearing trajectories in Niakhar, Senegal, between the early ...

The Impact of the COVID‐19 Pandemic on Childhood Cancer Survival: A Population‐Based Assessment of Survival Patterns Between 2015 and 2023 in Germany

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Numerous international studies have reported declines in new cancer diagnoses, delayed diagnoses and disruptions in cancer treatment following the implementation of COVID‐19 pandemic public health measures, raising concerns that these effects may ultimately contribute to increased cancer mortality.

Online Safety Zone Estimation and Violation Detection for Nonstationary Objects in Workplaces

IEEE Access, 2022
This study presents a deep neural network (DNN)-based safety monitoring method. Nonstationary objects such as moving workers, heavy equipment, and pallets were detected, and their trajectories were tracked.

Limiting sets of trajectories of a pendulum-type system [PDF]

Proceedings of the American Mathematical Society, 1956
here G(0, z) is continuous in (0, z) and satisfies some condition (such as a Lipschitz condition) which insures the uniqueness of the solution of (1) at each ordinary point. We also suppose that G(0+2wx, z) = G(0, z) for all 0, and that G(0, 0) = 0 has at most a finite number of roots on 0 ...
