The optimization issues connected to a landing task of an unmanned aerial vehicle are discussed in the paper, based on a model of a mini-class drone.Three landing scenarios are considered, including minimum-time landing, landing with minimum energy consumption, and planned landing.With the use of classical dynamic programming techniques, including
The fluvial landscape of the Hengchun Peninsula in southernmost Taiwan is generally characterized by a narrow river and a wide valley plain.Such underfit stream features are unusual in tectonically active areas such as Hobby Max Taiwan.In this research, we hypothesize that the relative sea level change since the end of the last glacial period might
Fish consumers may develop allergic reactions following the ingestion of fish products Accessories containing nematode larvae within the genus Anisakis.Sensitized patients may cross-react with proteins from insects, mites and mollusks, leading to allergic reactions even in the absence of the offending food.Potential cross-reactivity in Anisakis-all
Ankyloglossia is an uncommon congenital oral anomaly that can cause difficulty with breast-feeding and speech articulation.For many years, the subject of ankyloglossia has been controversial with practitioners of many specialties having widely different views regarding its significance and management.This study is about a series of five cases of an
Alightweight polymer composite with a broad bandwidth, tunable absorption frequency and multi-functionality is an ideal material for making a radar absorber.In general, composite microcellular foams have many potential applications due to their lightweight, high mechanical properties and monotonous cell structure.In this research, the effect of foa
