Communication and Preparedness Issues on Various Scales from Extreme Atmospheric Hazards

Most federally declared disasters are from atmospheric hazards. These could be from floods, tropical cyclones, tornadoes, or winter storms. Some of these hazards are events with relatively short warning times such as tornadoes or have sufficient warnings from tropical cyclones. This research examined communication of weather information and personal preparedness following the Florida landfall from Tropical Storm Debby in 2012. Another case study examined emergency management issues such as preparedness and response after the 2011 tornado in Tuscaloosa, Alabama. The concentration was on emergency management agencies at the County, University, State, and Federal levels. A sample of elderly residents of Pinellas and Pasco Counties in Florida completed a self-administered survey to examine various means of receiving weather information along with hurricane preparedness actions. In-depth interviews were conducted with representatives of various agencies on different scales in regard to preparedness and response following the Tuscaloosa tornado. The elderly used television as the primary means of receiving weather information, thus stressing the importance of utilizing both traditional and newer forms of communications to reach all citizens. One of the major issues on all levels following the Tuscaloosa tornado is related to communications such as resource allocations and response actions

TE Wave Measurement and Modeling

In the TE wave method, microwaves are coupled into the beam-pipe and the effect of the electron cloud on these microwaves is measured. An electron cloud (EC) density can then be calculated from this measurement. There are two analysis methods currently in use. The first treats the microwaves as being transmitted from one point to another in the accelerator. The second more recent method, treats the beam-pipe as a resonant cavity. This paper will summarize the reasons for adopting the resonant TE wave analysis as well as give examples from CESRTA and DA{\Phi}NE of resonant beam-pipe. The results of bead-pull bench measurements will show some possible standing wave patterns, including a cutoff mode (evanescent) where the field decreases exponentially with distance from the drive point. We will outline other recent developments in the TE wave method including VORPAL simulations of microwave resonances, as well as the simulation of transmission in the presence of both an electron cloud and magnetic fields.Comment: Presented at ECLOUD'12: Joint INFN-CERN-EuCARD-AccNet Workshop on Electron-Cloud Effects, La Biodola, Isola d'Elba, Italy, 5-9 June 2012; CERN-2013-002, pp. 193-20

A near-field scanned microwave probe for spatially localized electrical metrology

We have developed a near-field scanned microwave probe with a sampling volume of approximately 10 micron in diameter, which is the smallest one achieved in near-field microwave microscopy. This volume is defined to confine close to 100 percent of the probe net sampling reactive energy, thus making the response virtually independent on the sample properties outside of this region. The probe is formed by a 4 GHz balanced stripline resonator with a few-micron tip size. It provides non-contact, non-invasive measurement and is uniquely suited for spatially localized electrical metrology applications, e.g. on semiconductor production wafers.Comment: 6 pages, 3 figures, submitted to Appl.
