Efficient ways to learn weather radar polarimetry / Qing Cao in IEEE transactions on education, Vol. 55 N° 1 (Février 2012) 

Public ISBD [article]  in IEEE transactions on education > Vol. 55 N° 1 (Février 2012) . - pp. 58 - 68 Titre : Efficient ways to learn weather radar polarimetry Type de document : texte imprimé Auteurs : Qing Cao, Auteur ; Yeary, M.B., Auteur ; Guifu Zhang, Auteur Année de publication : 2013 Article en page(s) : pp. 58 - 68 Note générale : education Langues : Français (fre) Mots-clés : electromagnetic  scattering;  precipitation;  radar  polarimetry;  retrieval;  weather  radar Résumé : The U.S. weather radar network is currently being upgraded with dual-polarization capability. Weather radar polarimetry is an interdisciplinary area of engineering and meteorology. This paper presents efficient ways to learn weather radar polarimetry through several basic and practical topics. These topics include: 1) hydrometeor scattering model and calculation of radar variables; 2) characteristics of polarimetric radar measurements and radar echo classification; and 3) rain microphysics retrieval. The supporting files, data, codes, and results are provided on the Web site http://arrc.ou.edu/~guzhang/Polarimetry/main.html. The study modules provide hands-on experience in the area of weather radar polarimetry and related fields.

Reversing the trend of engineering enrollment declines with innovative outreach, recruiting, and retention programs / Chad E. Davis in IEEE transactions on education, Vol. 55 N° 2 (Mai 2012) 

Public ISBD [article]  in IEEE transactions on education > Vol. 55 N° 2 (Mai 2012) . - pp. 157 - 163 Titre : Reversing the trend of engineering enrollment declines with innovative outreach, recruiting, and retention programs Type de document : texte imprimé Auteurs : Chad E. Davis, Auteur ; Yeary, M.B., Auteur ; James J. Sluss, Auteur Année de publication : 2013 Article en page(s) : pp. 157 - 163 Note générale : Education Langues : Anglais (eng) Mots-clés : Electrical  and  computer  engineering  (ECE)  Engineering  Enrollment  Outreach  Recruiting  Retention Résumé : This paper discusses an all-encompassing approach to increase the number of students in engineering through innovative outreach, recruiting, and retention programs. Prior to adopting these programs, the School of Electrical and Computer Engineering (ECE) at the University of Oklahoma (OU), Norman, experienced a reduction in engineering enrollment similar to the trend that has occurred across the U.S. over the last few years. As a result, the school investigated the key factors that influence selection of engineering as a career path and initiated a corrective program to reverse this trend. The program involves focusing on the present through retention, on the immediate future through recruiting, and on the distant future through outreach. The focus of all of these programs is to mobilize the OU-ECE faculty and student body to present advanced engineering technologies, innovative demonstrations, and hands-on activities at a level that the individual student can understand and appreciate. Student surveys and interviews are used to assess the program qualitatively, and OU-ECE enrollment numbers are used as a quantitative assessment.
