The promise of multicyclic control

Several types of rotors which employ multicyclic control are reviewed and compared. Their differences are high-lighted and their potential advantages and disadvantages are discussed. The flow field these rotors must operate in is discussed, and it is shown that simultaneous elimination of vibration and oscillatory blade loads is not an inherent solution to the roughness problem. The use of rotor blades as energy absorbers is proposed. Input-output relations are considered and a gain control for ROMULAN, a multicyclic controlling computer program, is introduced. Implications of the introduction of multicyclic systems into helicopters are discussed

Multicyclic jet-flap control for alleviation of helicopter blade stresses and fuselage vibration

Results of wind tunnel tests of a 12 meter-diameter-rotor utilizing multicyclic jet-flap control deflection are presented. Analyses of these results are shown, and experimental transfer functions are determined by which optimal control vectors are developed. These vectors are calculated to eliminate specific harmonic bending stresses, minimize rms levels (a measure of the peak-to-peak stresses), or minimize vertical vibratory loads that would be transmitted to the fuselage. Although the specific results and the ideal control vectors presented are for a specific jet-flap driven rotor, the method employed for the analyses is applicable to similar investigations. A discussion of possible alternative methods of multicyclic control by mechanical flaps or nonpropulsive jet-flaps is presented

Do You See What I See?: Exploring the Relationship Between OCD Symptomatology and Theory of Mind Ability

A great deal of research supports that Theory of Mind (ToM; the ability to make inferences about the emotions, beliefs, and intentions of others) is impaired in people with symptoms of schizophrenia, autism, bipolar disorder, panic disorder, and obsessive compulsive disorder (OCD), to name a few. The present study focused on OCD, hypothesizing a negative correlation between the presence of OC symptomatology and ToM ability. Participants (N = 179) were undergraduate students from Butler University as well as participants recruited from mental health facilities, hospitals, and other organizations in the Indianapolis area. Participants completed several questionnaires, including measures of ToM (the Reading the Mind in the Eyes test, the Hinting task) and OCD symptoms (the OCI-R). As hypothesized, higher OC levels correlate with lower levels of some aspects of ToM
