Autonomous landing is one of the must-have operations of unmanned aerial vehicles such as drones. In this paper we describe an approach for fully autonomous landing of AR.Drones. This approach consists of two components – identifying and recognizing a proper pattern used to mark the landing area and reaching the landing area (landing) even if small disturbances occur. We discuss possible patter...

Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...

Exploration class human spaceflight missions will require astronauts with robust immune systems. Innate immunity will be an essential element for the healthcare maintenance of astronauts during these lengthy expeditions. This study investigated neutrophil phagocytosis, oxidative burst, and degranulation of 25 astronauts after four space shuttle missions and in nine healthy control subjects. Spa...

Background: Studies on how the shoe insole hardness regulate joint stiffness and transfer energy in the lower extremity during jump landing are scarce. The current study aimed to determine the effectiveness of shoe insole changes in joint power and stiffness during landing from jumps. Methods: Fifteen healthy male athletes volunteered to perform jump-landing in various shoe insole conditions. ...

Due to the relative infancy of Parkour there is currently a lack of empirical evidence on which to base specific technique instruction upon. The purpose of this study was to compare the ground reaction forces and loading rates involved in two Parkour landing techniques encouraged by local Parkour instructors and a traditional landing technique recommended in the literature. Ten male participant...

Landing of an UAV is a most complicated and important operation for autonomous flight operations. Most of the UAVs are operate with external pilots. Nowadays it is essential to design the advance automatic landing control systems to reduce the work load of external pilots in the landing process of UAVs. In this paper various auto rectification landing systems using fuzzy logic has studied and d...

UNLABELLED The repeal of the Direct Ground Combat Assignment Rule has renewed focus on examining performance capabilities of female military personnel and their ability to occupy previously restricted military occupational specialties. Previous research has revealed female Soldiers suffer a greater proportion of musculoskeletal injuries compared to males, including a significantly higher propor...

London Heathrow airport is one of the busiest airports in the world as it is very popular with both airlines and passengers. The capacity of the departure system at Heathrow is limited by the capacity of the runway. It is therefore imperative to maximise the throughput of the single available departure runway. Aircraft taxi from the stands to the ends of the runway where they queue in holding p...

Unmanned aerial vehicles (UAVs) have been carefully optimized for forward flight regimes over the past fifty years. While engineers learned to construct highly maneuverable craft to be flown by human operators, autonomous control of such highly underactuated systems has continued to be a difficult issue. New flight capabilities for aircraft have been enabled through recent advances in materials...
