Transverse loop oscillations observed by the Atmospheric Imaging Assembly (AIA) instrument on the Solar Dynamics Observatory (SDO) spacecraft are studied after an impulsive solar flare eruption on 2012 May 8. We have found that a transversely oscillating coronal loop seen in the 171 Å bandpass oscillates in anti-phase with respect to adjacent larger loops seen in the 193 Å and 211 Å bandpasses....

Introduction / objectives A US study published in the Journal of Food Protection in 2006 shows that only 32% of food processing-industry workers wash their hands properly. Compliance with proper hand hygiene practices is less than 40% in the healthcare sector. After more than five years of research and development, Cascades entered the Intelligent paperTM market with a novel approach in the fig...

We present observations of the formation, propagation and decay of vortexshaped features in coronal images from the Solar Dynamics Observatory (SDO) associated with an eruption starting at about 2:30UT on Apr 8, 2010. The series of vortices formed along the interface between an erupting (dimming) region and the surrounding corona. They ranged in size from several to ten arcseconds, and traveled...

This paper presents design of an ultra high speed 2x2 polymer electro-optic waveguide switch. Proposed switch has very short switching time (0.47 ps) and trapezoidal grating has following optimized parameters: coupling length, 81 mm; and switching voltage at operating wavelength of 1550 nm, 8.5 V. Proposed switch with smaller size, lower requirement of drive voltage and shorter switching time t...

Systems with smart textiles for personal protection are in place, but do not possess good communication links and communication structures. An open, service-oriented communications platform has been set as a goal. Mostly, these systems are based on technologies from a research area and not realize the full potential of available technologies. For this reason, technologies in the sciences, healt...

mechanical relays, the ever-shrinking geometries of semiconductor devices makes the thermal design of these solid-state power components increasingly diffi cult. One solution is to overcome this trend with the capabilities of the process itself by providing the device with onboard intelligent driving. STMicroelectronics 26 AUTO ELECTRONICS | SEPTEMBER/OCTOBER 2006 Figure 1. Current-generation f...

Development in the protection scheme highlighting the issues based on two complementary protocols i.e., Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR). These two topologies could mitigate the issue of redundancy to a large extent by building this feature within the protection scheme. It overcomes a link or a switch or a node failure during a zero switchover o...

Novel intelligent technique is a combination of fuzzy and neural network techniques that can be used to classify faults in electric power system protection. There have two problems in the protection system, which are: undesired tripping and fail to operate. Loss of power supply to relays and circuit breakers or failure in protective devices may cause failures in protection system. Construction ...

The popularity of mobile devices, especially intelligent mobile phones, significantly prompt various location-based services (LBSs) in cloud systems. These services not only greatly facilitate people’s daily lives, but also cause serious threats that users’ location information may be misused or leaked by service providers. The dummy-based privacy protection techniques have significant advantag...
