This study compares the OV1-10 satellite measurements of the integral airglow intensities at 630 nm in the SAR arc regions observed in the northern and southern hemisphere as a conjugate phenomenon, with the model results obtained using the time-dependent one-dimensional mathematical model of the Earth ionosphere and plasmasphere (the IZMIRAN model) during(More)
The atomic oxygen ®ne structure cooling rate of thermal electrons based on new e€ective collision strengths for electron impact excitation of the ground-state 3 P ®ne-structure levels in atomic oxygen have been ®tted to an analytical expression which is available to the researcher for quick reference and accurate computer modeling with a minimum of(More)
BACKGROUND Cross-sectional research has demonstrated poorer function and health-related quality of life (HRQOL) in those with multiple sclerosis (MS) but less is known about change over time. The goals of this study were to measure change in HRQOL and identify factors associated with change. METHODS HRQOL was assessed at baseline and annually over two(More)
We present a comparison of the observed behavior of the F-region ionosphere over Millstone Hill during the geomagnetically quiet and storm periods of 6±12 April 1990 with numerical model calculations from the IZMIRAN time-dependent mathematical model of the Earth's ionosphere and plasmasphere. The major enhancement to the IZMIRAN model developed in this(More)
Measurements of F-region electron density and temperature at Millstone Hill are compared with results from the IZMIRAN time-dependent mathematical model of the Earth's ionosphere and plasmasphere during the periods 16–23 March and 6–12 April 1990. Each of these two periods included geomagnetically quiet intervals followed by major storms. Satisfactory(More)
In this paper, a novel technique is presented for real-time identification of Induction Motor (IM) parameters. The method is based on the IM model in the synchronously rotating frame and it utilizes sinusoidal PWM voltage signals for parameters identification tests. The proposed algorithm provides accurate estimation of the stator and rotor parameters based(More)
Previously, Multimer Detection System (MDS) detected scrapie infected lambs of 8 mo age at pre-clinical stage in comparison with the normal controls. Above lamb were born from scrapie infected parent sheep (VRQ/VRQ). Here, MDS was challenged twice blindly with scrapie sheep blood samples from pre-clinical stages. These sheep showed no symptoms and they died(More)
We present a comparison of the electron density and temperature behaviour in the ionosphere and plasmasphere measured by the Millstone Hill incoherent-scatter radar and the instruments on board of the EXOS-D satellite with numerical model calculations from a time-dependent mathematical model of the Earth's ionosphere and plasmasphere during the(More)
