In order to enhance the pertinency of suspension parameters optimization for a rail vehicle, this research intends to reveal the influence rule of suspension Apron parameters on dynamic performance using sensitivity analysis method based on a virtual prototype response surface method model.Dynamic indexes in different combinations of suspension par
In memoriam of Dr.H.Peter STEINHAGEN Although the increasing economic importance of Eucalyptus lumber to furniture and other value added products manufacturing, its industrial use is still small.One of the main reasons is the difficulty to dry the lumber and related loses of row material.There is a general recommendation in literature to use a low
This paper presents a high-power microwave oscillator using a recursive balanced amplification technique.The proposed architecture is configured by a balanced power amplifier (BPA) with class-AB operation and two feedback networks.Each feedback circuit consists of a phase shifter and a high-Q Drain Collector Hose bandpass filter (BPF).The BPA consi
Accessing research participants within some social institutions for research purposes may involve a simple single administrative event.However, accessing some institutions to conduct research on their data, personnel, clients or service users can be quite Pentair Bermuda Skimmer Parts complex.Research ethics committee chairpersons frequently field
The umbrella species concept is often used as a tool to guide management Policosanol decisions and focus efforts towards one focal species whose habitat needs overlap that of other species.We assessed this concept in the context of an agriculturally dominant landscape using one of the most well-studied avian species in North America as a target for
