developed in the 1930’s and 1940’s3, 4, basic concepts of thermally coupledcolumns are not typically taught in undergraduate separations courses. Although they are taughtin some design courses, they are not included in the design courses at Mississippi StateUniversity. Due to the renewed interest in process intensification, a module on thermallycoupled columns is being added to an undergraduate separations course. Page 23.177.3ImplementationThe class is a junior level separations course that focuses on equilibrium staged operations,particularly distillation columns.

conservation as well asdevelopment of renewable energy resources must be vigorously pursued in order to find asolution to this dilemma. The entire public must be vested towards making a transition from afossil fuel based society to one that utilizes a far greater amount of renewable energy resources.According to Elder (2009) “Higher education has a critical role to play in this transition, much asit did during the space race of the 1960s. Our colleges can - and must - help students understandthe complex connections and interdependencies among our environment, energy sources, andeconomy - all of which underpin the green movement.”[1]The present situation is very similar to the 1960’s when the entire country was unified towardsplacing a man on the moon

So a low cost robotic applicationwas sought for a pilot course taught in the summer of 2012.Robots have been used in education for some time. Penn State began using robots of its owndesign in its freshman program in the mid-1990’s. Typical sub-group size was kept about threestudents with good success.7 Northeastern University also uses project base learning, andincorporates semi-custom kits to teach programming and electronics. The hands-on approachwas met with a high degree of student approbation.4Louisiana State University uses project based freshman courses that include programmablecontrollers and small robots.2

Wireless sensor modules were developed which can be attached to thePHAS or the patient. The modules are portable and have onboard power. These modules can alsobe used to record the range of joint motion of any human body segment with little modification.The gait data was reported on a normal healthy person acts as a reference database.References: 1.

, and farther from their day-to-day needs. Eventhough each individual house may have increased insulation, better windows, and high efficiencyheating and cooling systems, the total energy use goes up because of the larger size, greaternumber of electrical gadgets, and farther travel distances. More generally, this tendency forincreases in efficiency to lead to greater energy use is called the Jevons Paradox.2 These trendsare illustrated in Fig. 1. House size increased slowly through the 1980’s and then more rapidly inthe 1990’s and 2000’s. Because housing codes and building practices generally improved theefficiency of houses with time, the energy use per square foot steadily declined.

Compare participant O-01802’s behavior with O-11801 who is mostly off-task, butoccasionally “checks in” to lecture. We also observe various on-task and off-task durationperiods. For example, participants O-02802 and O-03803 have long on-task duration periodswhereas O-05801 and O-05802 have very short on-task periods. Participant O-07802 is off-taskfor nearly the entire lecture (on-task for only 4% of lecture), while participant O-06801 is on-taskfor the entire lecture.
