Computational Introduction to STEM StudiesAbstractWe report on the content and early evaluation of a new introductory programming course “Media PropelledComputational Thinking,” (abbreviated MPCT and pronounced iMPaCT). MPCT is integrated into afreshman-level entering students program that aims at retaining students by responding to the academicrecruitment and attrition challenges of computer science and other STEM disciplines.This course is intendedto provide meaningful experiences of relevance to students choosing majors that also fortifies theirqualitative understandings of foundational math and physics concepts. MPCT‟s activities are designed to provide analytical challenges typical of STEM professions and tomotivate additional inquiry

The SDR domains provides a methodto tie together many of the subjects in a typical electrical engineering and computer science andengineering undergraduate’s curriculum. Although student teams may choose to use whateverdevelopment environment they wish, we have had success with the GNU Radio developmentenvironment as well as the MATLAB Simulink environment. Simulink allows a model-baseddesign approach, which allows students to take a systems approach to designing the overall SDRtransceiver, which provides them with exposure to this important aspect of project development.In this paper, we discuss the

In this scheme, each mobile node with an omni-directional, single-element antenna estimates the AOT based on one (or more than one) signature signal(s)transmitted from the fixed node equipped with an antenna array. The mobile node then furtherestimates its distance from the fixed node based on the RSS of the signature signal to ultimatelybe able to pin-point its location in the polar coordinates where the fixed node is assumed to be atthe origin.
