Variable Stability Transfer Function Simulation
… of the performance of these aircraft. Such a variable stability simulation model was created based on 46 stability parameters, including natural frequencies, damping ratios, time constants, and gains. The simulation was obtained using transfer functions representing the aircraft state …

Terminal control of a variable-stability slender reentry vehicle
Various terminal control schemes are applied to a proposed slender reentry vehicle, controlled by two separately-articulating flaps. The flap deflections are summarized as symmetric and asymmetric flap deflections; the former manipulates the drag, lift-curve slope, and static margin; the latter …

Investigation of Lateral-Directional Coupling in the Longitudinal Responses of a Transfer Function Simulation Model
The linear variable stability Transfer Function Simulation Model (TFSM), inspired by the United States Air Force's NF-16D Variable stability In-flight Simulator Test Aircraft (VISTA) and created by Henrik Pettersson, can simulate any desired aircraft. The TFSM represents a non-linear aircraft model …

Limit Cycle PIO Analysis With Simultaneously Acting Multiple Asymmetric Saturation
… performed on a model based on the USAF NT-33A variable stability aircraft with nonlinearities including stick position limiting, elevator deflection limiting, and elevator rate limiting. These analyses involve the use of dual input describing functions which enable the prediction of frequency, …

Engineering non-immunoglobulin binding proteins for in vitro diagnostic Tests
… for use in in vitro applications, including variable stability from clone to clone, long developmental timelines, and structural complexity.

Early Maladaptive Cognitive Schema as a Predictor of Post-Stroke Depression
… of chronic phase depression. Additional variables of health locus of control, social support and level of disability, among others, were also explored as covariates and predictors of post-stroke depression. Further objectives included the assessment of EMS and psychosocial variable …

Stability analysis for soybean (Glycine max (l.) Merrill) Cultivars in Eastern South Dakota Environments
… as correlation, mixed linear model approaches, stability methods, and conditional approach to determine stability of these soybean cultivars and factors associated with yield stability. A differential environment specific phenotypic correlation effect was found which could have conferred …
