Wood-boring beetles in the family Cerambycidae (Coleoptera) play important roles in many forest ecosystems. However, increasing numbers of invasive cerambycid species are transported to new countries by global commerce and threaten forest health in the United States and worldwide. Our goal was to identify effective detection tools for a broad array of cerambycid species by testing some known ce...

It is widely recognized that simulation is pivotal to vehicle development, whether manned or unmanned. There are few dedicated choices, however, for those wishing to perform realistic, end-to-end simulations of unmanned ground vehicles (UGVs). The Virtual Autonomous Navigation Environment (VANE), under development by US Army Engineer Research and Development Center (ERDC), provides such capabil...

The main focus of this study is to apply a computational tool for the flow analysis of the turbine engine that has been tested with ice crystal ingestion in the Propulsion Systems Laboratory (PSL) at NASA Glenn Research Center. The PSL has been used to test a highly instrumented Honeywell ALF502R-5A (LF11) turbofan engine at simulated altitude operating conditions. Test data analysis with an en...

The technical task of creating new designs submersible vane pumps is to maintain stable operating parameters and increase the productivity pumping station with periodic regeneration sediment removal. well contains an outer chamber inner chamber, in which a unit installed, pipelines are connected lower upper pools. In structure under study, parts chambers equipped sealed head, part stopper. side...

In order to study the influence of position bulb on hydraulic performance a submersible tubular pump device, based large-scale pumping station, two schemes—involving front-mounted and rear-mounted bulb, respectively—were designed. The scheme uses GL-2008-03 model its conventional guide vane, while optimized design diffuser vane. method combining numerical simulation experimental testing was use...
