Helios Prototype
The Helios Prototype was the fourth and final aircraft developed as part of an evolutionary series of solar- and fuel-cell-system-powered unmanned aerial vehicles. AeroVironment, Inc. developed the vehicles under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program. They were built to develop the technologies that would allow long-term, high-altitude aircraft to serve as atmospheric satellites, to perform atmospheric research tasks as well as serve as communications platforms. It was developed from the NASA Pathfinder and NASA Centurion aircraft.

Helmet Effectiveness and Collaborative Networks Analysis
As an emerging transport tool, electric bicycles (e-bikes) have been widely used due to their low cost and convenient travel characteristics. Numerous studies have shown that the failure to properly use seat belts and safety helmets is one of the major causes of road traffic accidents.

Hemorheology
Hemorheology, the study of cell deformation and blood flow, has been more focused on red blood cells (RBCs) rheology, relating the deformation and aggregation of RBCs, since erythrocytes comprise the major components in blood. Blood rheology can be used as an important clinical assay, correlating various aspects of blood rheology and associated changes in cell behavior and morphology to a wide range of diseases and health conditions.

Hemp as Internal Curing Agent in Concrete Materials
The construction industry is facing increased demand for adopting sustainable 'green' building materials to minimise the carbon footprint of the infrastructure sector to meet the United Nations 2030 Sustainability Goals. Natural bio-composite materials such as timber and bamboo have been widely used in construction for centuries. Hemp has also been used in different forms in the construction sector for decades for its thermal and acoustic insulation capability owing to its moisture buffering capacity and thermal conductivity.

Hepatic Vessel Skeletonization
Hepatic vessel skeletonization serves as an important means of hepatic vascular analysis and vessel segmentation. Skeletonization provides an effective and compact representation of an image object by reducing its dimensionality to a centerline while preserving the original topologic and geometric properties. Hepatic vascular analysis plays a critical role in the diagnosis and treatment of many liver diseases, classification of liver function regions and inquiry into the nature of vascular growth. Hepatic vessel skeletonization serves as an important means of hepatic vascular analysis, particularly because a hepatic vessel is a kind of thin tubular object satisfying the growth principle of Murray’s law.
