Path planning is a significant problem in mission planning. For Miniature Air Vehicles (MAVs) exposed to strong winds, their flight paths are dynamically influenced by wind. Moreover, the small payload of MAVs severely restricts on-board computational resources. To alleviate the computational burden, a multi-resolution path planning approach for MAVs is presented, which is considering the knowledge...
In a combat simulation system based on High Level Architecture (HLA), different simulation models are usually called according to different simulation purposes. In order to improve the efficiency of developing different simulation systems, this paper designs and develops a Model Driven Platform of Combat Simulation System (MDPCSS) Based on HLA. MDPCSS drives each entity model through calling its model...
axial compressor is extensively used in modern gas turbine power stations. Because the effect of external contaminants and internal contaminants, particles entered in compressor are deposited in blade surface to change the blade geometry, thus thermal performance of compressor is influenced. Traditional flow simulation method defines the blade as rough wall with constant roughness. But experiment...
Four water-soluble polysaccharides named as SBP-11, SBP-12, SBP-13 and SBP-14 were obtained from Scutellaria barbata by defatting, boiling water extraction, deproteinating, decoloration and DEAE-52 chromatography purificaton. The carbohydrate content of SBP-11, SBP-12, SBP-13 and SBP-14 were 90.24%, 88.56%, 86.42% and 85.23%, respectively. SBP11 with molecular weight (MW) 1.8×104 D was composed of...
Objective: To develop a HPLC method for determining the contents of schisantherin and deoxyschizandrin in the dispersible tablets of Fructus Schisandrae Sphenanthera. Methods: The samples were extracted with methanol through supersonic wave and determined by HPLC on Hypersil ODS column (250mm × 4.6mm, 5µm) using methanol-water (73∶27, V/V) as a mobile phase. The flow rate was 0.8 mL/min and the detection...
