“…Comparing to the literatures by Shao, the power trends shown in Figure 8 matched the trends published by Shao [31]. The power values are not identical as different scooters are modeled but the trends are similar.…”

SUMMARYThis paper presents a parallel hybrid electric scooter model developed on MATLAB-Simulink. The hybrid electric scooter model was developed to further understand and analyze as well as to predict its performance before proper construction of the prototype begins. The model consists of four main models that formed the complete hybrid scooter model: battery model, engine model, DC motor model and the dynamics model. The multi-mode controller predicts the required parameters to operate the scooter in an optimize condition. Experimental data were gathered and thus compared to the simulated data to check the model's feasibility and accuracy on four distinct driving cycles: modified urban dynamometer driving schedule (UDDS), New York city cycle (NYCC), European driving cycle (ECE-15) and modified highway fuel economy driving schedule (HWFET). Basic studies showed that the model developed had a maximum of 4% error. Maximum error achieved between the theoretical and the experimental readings is about 3.15%, which is for the modified HWFET cycle. Other cycles have acceptable errors; UDDS cycle with 1.91%, NYCC cycle with a low 0.68% and ECE-15 cycle with 1.15%. Operating costs between the internal combustion engine mode, motor mode and hybrid mode were also estimated, where final results showed an 18% reduction of the overall fuel consumption using the multi-mode controller between hybrid scooters and conventional scooters. The fuel consumptions were also predicted and compared the estimated results with one commercially available hybrid scooter, Piaggio Vespa MP3 hybrid scooter. Primary results showed a 4.4% increase in distance travelled per kilometer.

“…Nevertheless, Qi is observable with a video camera although a conversion into its frequency spectrum is necessary to make the evidence accessible on sight. Second, the details of the meridian network within the limit of the study conform to the sketches given by the standard texts in Chinese medicine (10,11) and that of Huang Di Nei Jing Ling Shu (2). Thirdly, since acupuncture is pure science, its future employment could be quantified, particularly related to its clinical effectiveness.…”

Acupuncture is widely deployed today, but its basic physiology with Qi and meridian is not understood. This letter postulates that Qi is an infrasound wave packet and meridian is the muscle waveguide. Using video cameras and signal processing in an IRB approved clinical experiment we performed a comparison between control and electroactivated statistical tests on the long range (50-80cm) unidirectional transmission of Qi (p = 0.025). In the reverse direction, there is no transmission even in a distance of less than 10 cm (p = 0.545). The rectification is a surprise but in full agreement with Huang Di Nei Jing.
