ESA's Olympus set to launch a new satellite era

Launch of a new journal, beginning of a new era

According to the World Health Organization (WHO), chronic diseases (also called Noncommunicable Diseases, NCDs) are of long duration and generally with slow progression. NCDs include mainly cardiovascular diseases, cancers, chronic respiratory diseases and diabetes, and they are the world's most common diseases. A total of 38 million people die from chronic diseases each year, and almost three ...

Vitamin D: Is There a New Era?

  Background: In recent decades, much interest has been focused on investigating new roles of vitamin D in human body beyond the mineral-ion homeostasis. Methods: By searching medical databases such as PubMed, over 16000 articles were found which have been published since 2000 on novel aspects of vitamin D in health and diseases. Results: Of great interest was the effects of vitamin D on ...

Nonlinear Optimal Control Techniques Applied to a Launch Vehicle Autopilot

This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin Approximation (SGA), is used to obtain an approximate optimal solution. Simulation results invo...
