Terminal transient for minimum-time dash mission
… as consisting of three stages; a climb to the dash point,a steady-state dash at the high velocity point, and finally, a terminal transient from the dash point to the final state. This terminal maneuver evolves outside of the flight envelope, rapidly decreasing altitude while increasing the …

Singular trajectories in airplane cruise-dash optimization
The problem of determining cruise-dash trajectories is examined for the case of time-fuel optimization using a linear combination of time and fuel as the performance index. These trajectories consist of a transient arc followed by a steady-state arc. For cases where the steady-state arc is flown …

Singular-perturbation analysis of climb-cruise-dash optimization
The method of singular-perturbation analysis is applied to the determination of range-fuel-time optimal aircraft trajectories. The problem is shown to break down into three sub-problems which are studied separately. In particular, the inner layer containing the altitude path-angle dynamics is …

On-board near-optimal climb-dash energy management
Reduced order modelling has been extensively used in the solution of problems in flight mechanics. In particular the lowest-order attractive due to its simplicity, energy model is but because of the assumptions made (γ = 0.0) is of little use for realtime guidance. The method of matched asymptotic …

Injection locking characteristics of indium arsenide quantum dash lasers
… characteristics was performed on an InAs Quantum Dash (QDash) semiconductor laser for the first time. The linewidth enhancement factor(α-parameter) of a QDash laser was measured using an injection locking technique that takes advantage of the asymmetry of the injection range. Studies were …

Study of QoE for DASH at Sub-representational Level
… while streaming to ensure continuous playback. DASH provides sub-representation structure that can be extrapolated for refining QoE metric with multiple temporal quality operating point for a given spatial quality i.e. PSNR. In this work we use frame visual significance metric and frame loss …

The Relationship between Physical Activity and DASH Diet Adherence
… The Dietary Approaches to Stop Hypertension (DASH) diet has been shown to be effective in adolescents as a non-pharmacological treatment for elevated blood pressure. Other factors that influence adoption and adherence of the DASH diet are not yet fully understood. </p><p>Objective: To …

Cruise-dash optimization applied to an air-breathing missile
… is shown to lead to the reduced-order "cruise-dash" model, and this model is used in the optimization study. Earlier work in this area is extended by the inclusion of two not heretofore considered limits on the dynamical system. The results of the earlier work are shown to hold throughout much …

Numerical Simulation and Experimental Investigation of Quantum Dash Lasers at Elevated Temperatures: Design and Operation of Monolithic InAs/InP Quantum Dash Ridge Laser Diodes Operating in the C-Band
… device, a mode-locked ridge waveguide quantum dash laser. Quantum dash and dot gain media both exhibit spontaneous mode-locking, reduced sensitivity of their performance to temperature, and lower threshold current densities. Dashes additionally offer higher peak gain and broader gain …

Health management of adult hypertension in the United States: Results from the National Health and Nutrition Examination Survey (NHANES)
… The Dietary Approaches to Stop Hypertension (DASH) diet is a widely used dietary recommendation for individuals with hypertension. Even though adherence to the DASH diet has been shown to be effective, it is unclear whether hypertension diagnosis has an impact on adherence to the DASH diet and …

Babe (Body Appreciation and Better Eating), Just Add a Dash of Self-Compassion: A Randomized Controlled Pilot Study for Black/African American Teenage Girls
<p>Introduction</p> <p>Body dissatisfaction contributes to disproportionately high rates of disordered eating behaviors observed in Black teenagers. Given that self-compassion is found to buffer against eating pathology and body dissatisfaction and is linked to reduced incidences of binge eating …

Determining a Relationship Between Posterior Chain Flexibility and Linear Sprint Speed
… athletes usually produce the fastest 40-yard dash times. Flexibility, in this case specifically refers to posterior chain flexibility (PCF). This is usually measured by athletes ability to perform a sit-and-reach test. This train of thought has been widely accepted within the human performance …
