Previous investigations using flight testing and simulator studies have identified influence of vehicle flight speed and control system sensitivity on the bandwidth-phase delay criterion, not accounted for in the proposed new handling qualities criteria for rotorcraft (ADS-33C). In this paper, the impact of flight speed and control system sensitivity on handling qualities as depicted by the ban...

Background. Maximal Aerobic Power is related to many quantities and qualities such as supplements. Objectives. The purpose of the present study was to describe the effect of short-term supplementation of glutamine and glucose on hemoglobin and maximum aerobic power in female athletes. Methods. In this quasi-experimental study, 40 female athletes (age 21.9±2.6 years, height 161.8&...

{ We consider a packet data DS-CDMA network which supports multiple traac classes. Each traac class has a diierent requirement on information rate and performance. Given suucient bandwidth, these requirements can be satis-ed by an appropriate assignment of power and processing gain to the users in each class. For a single class of data users we examine the relationship between delay and process...

Over the past decade, NASA, under a succession of rotary-wing programs has been moving towards coupling multiple discipline analyses in a rigorous consistent manner to evaluate rotorcraft conceptual designs. Handling qualities is one of the component analyses to be included in a future NASA Multidisciplinary Analysis and Optimization framework for conceptual design of VTOL aircraft. Similarly, ...

we performed molecular dynamics simulations using the coarse-grained model to study the freezing behavior of pure water and 14% water-salt mixture in a wide range of temperatures for a very long time around 50 nanoseconds. for the salty water, an interface in nanoscale was used. for both systems, the freezing behavior of water molecules was studied using some qualities such as density, total en...

Traditional didjeridus have a broad range of unknown bore geometries, and consequently have advantages for examining relationships between subjective and physical parameters. This study involved 7 experienced players assessing each of 38 traditionally made didjeridus in terms of 8 subjective parameters. Their assessments were then correlated with detailed measurements of acoustic input impedanc...

Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...
