The Global Hawk Advanced Concept Technology Demonstration Was a Success

چکیده
The United States has seen a three-decade-long history of poor outcomes in unmanned aerial vehicle (UAV) development efforts. Technical problems have led to cost growth and schedule slip as well as to disappointing operational results. Costs have tended to escalate so much during development that the resulting systems have cost more than users have been willing to pay, precipitating program cancellation in almost every case. This history prompted the unique developmental approach adopted at the beginning of the HighAltitude Endurance Unmanned Aerial Vehicle (HAE UAV) program.

Aridity as a spatial concept and drought as a temporal concept have always been studied in different aspects as two distinct categories. However, both concepts indicate anomalies from normal condition. Several indices have been introduced to examine each of these concepts using one or more hydrological cycle’s components. Meanwhile, soil moisture and changes in its spatial and temporal va...
