This paper presents a method to control height and speed of fixed wing unmanned aerial vehicles (UAVs) using MATLAB platform. The mathematical dynamic model of Six Degrees of Freedom (6-DOF) aircraft is nonlinear and it is linearized about a flight condition. System is divided into two Multi Input Multi Output (MIMO) sub models. First model controls the longitudinal dynamics and second model is...

UNLABELLED Bioinformaticians are tackling increasingly computation-intensive tasks. In the meantime, workstations are shifting towards multi-core architectures and even massively multi-core may be the norm soon. Bag-of-Tasks (BoT) applications are commonly encountered in bioinformatics. They consist of a large number of independent computation-intensive tasks. This note introduces PAR, a scalab...

The Lister Hill National Center for Biomedical Communications is investigating a local area network approach to a system for the distribution of digital document images among a set of image retrieval and display workstations, each based on an AT-class computer. The goal of the study is to investigate rapid, online, multi-user access to a database of document images stored on optical disks. The ...

Deep sea exploration and exploitation are of an increasingly interest to human beings in the 21 century. Manned and unmanned deep submergence vehicles are necessary means for deep sea explorations. In order to fulfill the requirements of deep sea explorations of COMRA (China Ocean Mineral Resources R&D Association), a deep manned submersible is developed in China and it is now named “Harmony”. ...

UAVs are becoming ubiquitous due to their high-risk mission acceptance and ultra-long endurance capabilities. However, because a significant subset of UAVs have limited payload capacity and sensor ranges, teams of UAVs are often required to operate cooperatively in executing specific tasks (e.g., time-critical complex surveillance tasks requiring multiple UAVs) to ensure superior mission perfor...

An aircraft (manned aircraft) may enter safely and legally into the US National Airspace System if and only if it has an airworthiness certificate complying with Federal Aviation Administration requirements. Although corresponding requirements, procedures and regulations for unmanned aircraft are in early development stages, they are expected to be similar to those set for manned aviation. This...
