4. CGM (continuous glucose monitoring) measures the level of glucose in interstitial fluid. In contrast to the measurement of blood glucose, the method is noninvasive and may be conducted at a high frequency, e.g. every 5 min using a wearable device. Multiple studies indicated that, for nondiabetic individuals, the value should not rise above 140 mg/dL for one or two percent of the time every day. File CGMdata.txt contains the recordings from 57 participants. Columns in the file are DisplayTime (time stamp as recorded by the monitor), GlucoseValue (glucose concentration in mg/dL), subjectld (participant id number), and InternalTime (internal time stamp). The pattern below is from one of the participants with poor glucose regulation, showing a large spike following each main meal. The program CGM1_HW.mlx is designed to help you identify this participant by displaying all the CGM data as tiles. Places that need completion are marked as XXX.

5. What is the reflected intensity and the transmitted intensities for a 3 MHz transducer for impedances of 200 rayls and 50 rayls, given an initial intensity of 14 mW/cm² ?

7. What are the angles of reflection & transmission for a specular oblique reflector, given an angle of incidence of 40 degrees and propagation speed through medium 1 of 2.1 mm/us and propagation speed through medium 2 of 3.4 mm/us?

3. The dataset in breastTissuelmpedance.xlsx was obtained from University of California Irvine Machine Learning Repository. The study used electrical impedance for the diagnosis of freshly biopsied breast tissues, which measures how much AC signals are attenuated and/or delayed as they pass through the tissue. It is hypothesized that tissue impedance is altered by cancer due to changes in tissue structure or cell composition. A total of 9 measurements were made. However, some of them showed similar responses to cancer therefore provide redundant information. Replace XXX with appropriate code in the program breast Tissuelmpedance_HW.mlx to identify pairs for which the Pearson correlation coefficient is >0.8. 3 points.

ASSIGNMENT Need to do in 1-2 pages double spaced MLA Conceptualize a design for biosensor systems to comparatively evaluate the detection of a large tissue sample from a biopsy and a micro sample from say a bacterial or virus sample like COVID. This could be a diagram, or an essay outlines the possible specifications of the design.
