Subjective Cognitive Concerns and Cognitive Trajectories in Parkinson's Disease: Biomarker Impact [PDF]
ABSTRACT Objective To examine the relationship of subjective cognitive concerns (SCC) with biomarkers of Alzheimer's disease (AD), neurodegeneration, and Parkinson's disease (PD) and domain‐specific cognitive trajectories among cognitively unimpaired persons with de novo PD. Method Cognitively unimpaired participants with SCC (n = 294) and without SCC (

Preliminary design of multiple gravity-assist trajectories [PDF]
In this paper the preliminary design of multiple gravity-assist trajectories is formulated as a global optimization problem. An analysis of the structure of the solution space reveals a strong multimodality, which is strictly dependent on the complexity ...

Global optimisation of multiple gravity assist trajectories [PDF]
Multiple gravity assist (MGA) trajectories represent a particular class of space trajectories in which a spacecraft exploits the encounter with one or more celestial bodies to change its velocity vector; they have been essential to reach high Delta-v ...

Time-optimal trajectories to circumsolar space using solar electric propulsion [PDF]
The aim of this paper is to explore the capabilities of a solar electric propelled spacecraft on a mission towards circumsolar space. Using an indirect approach, the paper investigates minimum time of transfer (direct) trajectories from an initial ...

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

Jointly modeling time-varying offending profiles and criminal career trajectories in a sample of sexual offenders : A multivariate approach to modelling criminal careers [PDF]
The study begins by summarising three key topics of research in criminal careers of sexual offenders: explaining the observed bimodality of the age-crime curve for sexual offenders; determining whether rapists and child molesters follow well-separated ...

Optimal low-thrust trajectories to asteroids through an algorithm based on differential dynamic programming [PDF]
In this paper an optimisation algorithm based on Differential Dynamic Programming is applied to the design of rendezvous and fly-by trajectories to near Earth objects. Differential dynamic programming is a successive approximation technique that computes
