Development of the automatic autorotation landing control system by using a small unmanned helicopter by Takumi TOMITA, Daigo FUJIWARA

“…The control system is designed and validated based on the comprehensive helicopter dynamics model with an induced velocity model which is newly developed for descent at low speed. A rotational speed controller stabilizes main rotor speed during dive and is switched to descent speed / thrust controllers which reduce descent speed during flare. …”

Semantics of Quran’s Words in Tafsir al-Mizan by Hossain Khakpour, Maryam Bolourdi

“…This paper aims to investigate the meaning of the words of the Quran in Tafsir al-Mizan, and applies a descriptive-analytical research method with a Quranic approach to investigate the existing differences in Quran’s words and finally concludes that changes have been made in some Quranic words before and after the descent in a way that some Quranic words had almost the same meanings before the descent; however, they undergone some changes during the descent such similarity in meanings, expansion, integration, and so on. …”

Nontrivial Sha in the Jacobian of an Infinite Family of Curves of Genus 2. by Arnth-Jensen, A, Flynn, E

“…We give an infinite family of curves of genus 2 whose Jacobians have non-trivial members of the Tate-Shafarevich group for descent via Richelot isogeny. We prove this by performing a descent via Richelot isogeny and a complete 2-descent on the isogenous Jacobian. …”

Divergent mortality trends by ethnicity in Fiji by Richard Taylor, Karen Carter, Shivnay Naidu, Christine Linhart, Syed Azim, Chalapati Rao, Alan D. Lopez

“…Results: Over 1975–2008: IMR decreased from 33 to 20 deaths/1,000 live births in i‐Taukei (Fiji Melanesians); and 38 to 18 in Fijians of Indian descent. Increased adult male mortality among i‐Taukei and decline among Fijians of Indian descent led to an equal probability of dying in 2007 of 29%; while in female adults the probability trended upwards in i‐Taukei to 25%, and declined in Fijians of Indian descent to 17%. …”
