Details and the abstract submission tool may be found on the official website: http://ies2015.bc.edu. The good news is that the chairpersons of IES2015 (i.e., Dr. Keith Groves and Patricia Doherty) are allowing a few more days to those who have not yet submitted paper titles and abstracts in certain special session categories. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> In addition to a large number of subject categories that are familiar to IES attendees in previous editions, we are proposing the following:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>HF Communication and Surveillance Technologies exploiting HF propagation systems and techniques<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Papers are specifically solicited that address HF propagation technologies in applied systems such as communication, surveillance, direction finding, and emitter location. Additionally, papers describing new and improved HF methods and studies involving ionospheric diagnostics, including vertical, forward-oblique, and backscatter sounding technologies are welcome. Doppler sounding techniques and hybrid methods are also encouraged. Schema that can detect and characterize ionospheric inhomogeneities of various scales and durations, including TIDs, are emphasized since these phenomena are increasingly important in the performance of real systems. Novel techniques that employ the synergistic assimilation of Ionospheric data sets derived from HF sounders and other sources, including GPS-TEC, are encouraged. It is anticipated that more than one technical session will be organized to accommodate the specified topics. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>session chairman: <o:p></o:p></p><p class=MsoNormal>John Goodman, PhD<o:p></o:p></p><p class=MsoNormal>JMG Associates Ltd<o:p></o:p></p><p class=MsoNormal>jm_good@atmc.net<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Please submit your proposed paper through the interface on the Official Website (http://ies2015.bc.edu).
