An incoherent scatter radar study of the midnight temperature maximum that occurred at Arecibo during a sudden stratospheric warming event in January 2010
Authors: Gong Yun , Zhou Qihou , Zhang Shaodong , Aponte Nestor , Sulzer Michael 
Published: May 2016

AbstractWe present an analysis of the thermospheric midnight temperature maximum, a large increment of temperature around midnight. The analysis is based on data collected from the Arecibo incoherent scatter radar during 14–21 January 2010. The experiment overlaps with a major sudden stratospheric warming (SSW) event which commenced on 18 January 2010. Throughout the observation, the ion temperature exhibited moderate increase around postmidnight during 14–17 January, while it showed more intense increment during 18–21 January. In particular, on 20 January, the amplitude of the midnight temperature maximum (MTM) is 310 K, which is seldom seen at Arecibo. During the SSW, the meridional wind reverses toward the pole just before the commencement of the MTM. Then, the poleward wind and the ion temperature maximize almost at the same time. The variation of meridional wind and the MTM are consistent with the Whole Atmosphere Model (WAM) studies, which suggested that the variation is due to effects from an upward propagating terdiurnal tide. On the nights of 18–19 January, the MTM showed clear phase variation at the heights of 265, 303, and 342 km. A strong terdiurnal tide has been observed during the SSW and it is likely generated from low atmosphere and propagating upward. Our results provide direct observational evidence that the propagating upward terdiurnal tide plays an important role in causing the MTM, which supports the WAM simulations.
All‐Stabilizing Proportional Controllers for First‐Order Bi‐Proper Systems with Time Delay: An Analytical Derivation
Authors: Nesimioglu Baris Samim , Soylemez Mehmet Turan 
Published: May 2016

AbstractIn this paper, a simple derivation for an all‐stabilizing proportional controller set for first‐order bi‐proper systems with time delay is proposed. In contrast to proper systems, an extremely limited number of studies are available in the literature for such bi‐proper systems. To fill this gap in the literature, broader aspects of the stabilizing set are taken into consideration. The effect of zero on the stabilizing set is clearly discussed and we also prove that, when their zeros are placed symmetrically to the origin, the stabilizing set of non‐minimum phase plant is always smaller than that of the minimum phase one. Moreover, for an open‐loop unstable plant, maximum allowable time delay (MATD) is explicitly expressed as a function of the locations of the pole and zero. From that function, it is shown that for a minimum phase plant, the supremum of the MATD is two times that of the time constant of the plant and the infimum of the MATD is the time constant of the plant. We also prove that the supremum is the time constant and the infimum is zero for a non‐minimum phase plant.

AbstractThe photoaquation of (Cr(NH3)5I)2+ has been investigated in aqueous HClO4 with 546 nm‐irradiation at 8 °C. The results show that the iodo complex, like the chloro and bromo pentaammines, loses ammonia efficiently on irradiation into the ligand field bands with at most a minor yield of iodide.
