Abstract Unexpected short patches of natural VLF emissions at f > 5 kHz have been observed the ground station Kannuslehto (KAN, L ~ 5.5) in Northern Finland. In contrast with usual (e.g., chorus, hiss, and quasiperiodic emissions) these high-frequency bursty-patches are frequencies higher than half equatorial electron gyro-frequency shell KAN. Moreover, most waves reached above local gyrofre...

Predicting space weather effects of the solar wind requires knowing location and properties any embedded high speed streams (HSSs) or stream interactions regions (SIRs) that form as fast catches up to slow preceding wind. Additionally, this background affects evolution coronal mass ejections. We present Mostly Empirical Operation Wind with a High Speed Stream (MEOW-HiSS) model, which runs nearl...

This paper considers the problem of scheduling a given number of jobs on a specified number of identical parallel robots with unequal release dates and precedence constraints in order to minimize mean tardiness. This problem is strongly NP‐hard. The author proposes a hybrid intelligent solution system, which uses Genetic Algorithms and Simulated Annealing (GA+SA). A genetic ...

Plasmaspheric hiss is one of the most important plasma waves in Earth's magnetosphere to contribute radiation belt dynamics by pitch-angle scattering energetic electrons via wave-particle interactions. There growing evidence that temporal and spatial variability interactions are factors construction diffusion-based models belts. Hiss amplitudes thought be coherent across large distances on long...

Abstract We conduct electromagnetic particle simulations to examine the applicability of nonlinear wave growth theory generation process plasmaspheric hiss. firstly vary gradient background magnetic field from a realistic model rather steep model. Under such variation, threshold amplitude in increases quickly and overlap between optimum disappears correspondingly, is suppressed. In simulations,...

In rice (Oryza sativa L.), heat-induced spikelet sterility (HISS) has long been recognized a major threat in the production, and currently potential risk of yield reduction is likely to be increasing under global warming. However, there have few studies on HISS conducted field conditions. recent years Japan, extremely high temperatures frequently recorded daytime during summer. 2018, heat wave ...

Healthcare Information Systems (HISs) in hospitals have become an influential factor to provide cooperation among physicians in sharing healthcare information. Many cooperative HIS models were proposed. However, they focused on management of the patients’ information and do not address the issue of improving the physicians’ skills due to many factors. In this study, a mixed data collection appr...
