- Q2:3. 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.See Answer
- Q3:4. 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. Due 9/21, 3 points. الميساني 290 50 References: https://github.com/irinagain/Awesome-CGM/wiki/Hall-(2018)See Answer

- Q14: Signal Processing Project For this project, you will be applying several signal processing algorithms to several instances of a given type of one-dimensional data set of your choice. Possible choices include: A) ECG B) EEG C) speech D) ultrasound-based 1D dataset You will analyze at least 3 waveforms (1D) from the data set of your choice using 3 (or more) algorithms of your choice for a particular purpose. This makes a minimum of 3x3=9 analyses. That purpose could be to detect a feature or attribute of interest (like heart rate or the relative t wave amplitude for ECG), to analyze frequency content, or to reduce noise and enhance the signal, for instance. Possible algorithms include: a) peak finding b) frequency filtering c) smoothing d) noise reduction f) spectrogram g) short-time Fourier Transform (STFT) h) frequency content analysis You will share your preliminary results with a classmate during class and include a summary in your project report (for part of the grade). The final report (3-5 pages, not including code) will cover your own analysis. Specifically, include in a few paragraphs on each algorithm you used, describe: • what you did to implement the algorithm? . what were the results? (include figures) why/when is this useful? In your final project submission include: • analysis.m files data files (if not built in or provided on eLearning) project report document (.docx, .pdf) If you wish to propose a challenging project of your own talk to me individually. Ground rules: You need to do independent original work. While you may use built-in functions from MATLAB, do not copy the examples or use code directly copied from the web. It is OK to use such code for inspiration. Do not use a project from another course. You can get started with waveforms built into MATLAB (some are not available in latest MATLAB versions, so this also available as a .zip in eLearning): load wecg; % ECG signal sampled at 180 Hz load mit200% The ECG data and annotations are taken from the MIT-BIH Arrhythmia Database. The data are sampled at 360 Hz. load mit203 % The ECG data and annotations are taken from the MIT-BIH Arrhythmia Database (with noise). The data are sampled at 360 Hz. load Espiga3; % 23 channel EEG data sampled at 200 Hz Or, you can use waveforms from a UTD lab you are associated with, or from the web (Kaggle.com is a one source).See Answer
- Q15: BE 312 Lab #3 LAB 3: Stretch Receptors and Reflexes I. Background Studying the vertebrate stretch reflex is a good way to introduce students to the topics of stretch receptors, nerve conduction velocity, electromyograms (EMG), and motor control. Specialized receptors in the muscle respond to the stretching of the tendon attached to the muscle, and then send signals to motorneurons through a single synapse. The muscle fibers depolarize and twitch (contract) in response to the incoming impulse from the motorneuron. The Stretch Receptor Skeletal muscles have specialized receptors which convey information about muscle length, tension, and pressure to the central nervous system. The sensory receptors responsible for providing information about the length, or the rate of change of the length, of a muscle are called muscle spindles. Arranged in parallel with muscle fibers, the spindles are stretched when the muscle is stretched by an external force. Therefore, these receptors play a significant role in developing antigravity reflexes and maintaining muscle tone. Muscle spindles contain a small bundle of intrafusal fibers which do not contribute to the overall tension of the muscle, but regulate the excitability of the sensory afferent spindle nerves by mechanically deforming the receptors. These fibers are innervated by gamma motor neurons. Much of a muscle consists of extrafusal fibers, which are innervated by alpha motor neurons and are responsible for developing muscle tension. Motor Fibers Sensory Fiber Intrafusal Fibers Fluid Cavity Extrafusal Fibers Muscle Muscle Spindle Sensory Neuron Motor Endplates Motor Neuron Spinal Cord Figure HN-2-B1: A monosynaptic stretch reflex arc. The Stretch Reflex When a muscle is stretched, excitation of its muscle spindles causes a reflex contraction of the muscle. This reflex response is known as a stretch (myotatic) reflex. The minimal delay between the muscle stretching and the reflex contraction is due to its monosynaptic pathway. The sensory afferent nerves from the spindles synapse directly with motor neurons; there are no interneurons. This pathway constitutes the shortest possible reflex arc. 1 BE 312 Lab #3 Rectus Femoris Vastus Lateralis Patellar Ligament Tibialis anterior Tibia -Biceps Femoris Femur -Soleus -Gastrocnemius (Lateral Head) - Fibula Achilles Tendon HN-2-1 Figure HN-2-B2: The major extensors and flexors of the human knee and ankle joints. The stretch reflexes used in this exercise are elicited by striking the patellar tendon or the Achilles tendon. As an example of the stretch reflex, consider the reflex response that occurs when a person jumps from a low stool to the floor. The extensor muscles of the legs are stretched on landing, lengthening all their muscle spindles. The discharge of the muscle spindles is conveyed to the central nervous system through the fast-conducting afferent axons. These sensory axons enter the spinal cord through the dorsal root and synapse with the motor neurons of the same extensor muscle. In turn, the motor neurons trigger the contraction of the extensor muscle to oppose the stretch produced by landing, completing the reflex arc. This reflex is one of the main reasons you keep your balance and do not fall when changing certain body positions. In this lab, students will record electromyograms (EMGs), the summation of asynchronous electrical activity (muscle action potentials) in the multiple fibers in the muscle, and use them to determine the time between the stretch of the tendon and the arrival of the motor impulse at the muscle. Two reflexes in a human subject will be studied: the Achilles tendon reflex, and the patellar tendon (knee-jerk) reflex. Conduction times and nerve velocities for each reflex arc will be determined and compared. The effect of pre-existing tension in the effector muscle, or motor activity in other muscle groups, upon reflex responses will be measured. The coordination of motor activity in antagonistic muscles will also be studied. 2 BE 312 Lab #3 II.

Attach the two color-coded electrode leads as shown in Figure 2 for the Achilles Reflex. III. Experiments Exercise 1: Achilles Tendon Reflex Aim: To determine conduction time from tendon tap to response of the gastrocnemius muscle in the Achilles tendon reflex arc. Approximate Time: 20 minutes Procedure 1. Instruct the subject to sit on a lab bench so that the subject's thighs are supported by the top of the bench and his or her calves hang freely. 2. The Achilles tendon is located above the heel and connects the gastrocnemius muscle to the tarsal bone of the foot. Tap the tendon with the wide end of the reflex hammer a few times to locate a point on the tendon which produces a consistent contraction of the gastrocnemius muscle and a downward movement of the foot (plantar flexion). The opposite, upward movement is known as dorsiflexion. 3. Click Record and then instruct the subject to move his or her foot up and down to demonstrate the type of EMG that occurs during plantar flexion and dorsiflexion. Click AutoScale All. 4. Type Achilles in the Mark box. Click the mark button to mark the recording. Continue recording. 5. Tap the subject's Achilles tendon to elicit the stretch reflex. Record a total of five trials using the same tapping force. 6. After the fifth trial, click Stop to halt recording. 7. Select Save As in the File menu, type a name for the file. 8. Repeat this exercise on the same subject using three different amounts of force. Exercise 2: Patellar Tendon (Knee Jerk) Reflex Aim: To determine conduction time from tendon tap to response of the quadriceps muscle in the patellar tendon reflex arc. Approximate Time: 40 minutes Software Changes Click on the Settings menu and select the PatellarStretchReflex settings file. Procedure 1. Instruct the subject to sit on a lab bench so that the subject's thighs are supported by the top of the bench and his or her calves hang freely. 2. Remove the lead wires of the EMG recording cable from the electrodes over the subject's calf muscle. Keep these electrodes on the subject's calf muscle. 3. Place a new set of recording electrodes on the quadriceps muscle of the subject on the medial side of the thigh, so that: the black (-1) lead wire is attached to an electrode which is about 12 cm from the knee. 4 BE 312 Lab #3 the red (+1) lead wire is attached to an electrode which is about 10 cm above the negative electrode (see Figure 3). RAM Figure 3. Circuit diagram for recording EMGs from the thigh muscles. Using the iWireB3G on the left and the wireless ROAM on the right. Note: Ignore the green wire 4. Feel the position of the patellar tendon just below the kneecap. Place one hand on the patella (kneecap), and use the other hand to tap the patellar tendon with the reflex hammer. Find the point on the patellar tendon that causes the greatest response from the quadriceps muscle. 5. Click Record and then instruct the subject to raise and lower his or her lower leg to demonstrate the type of EMG that occurs during quadriceps contraction and relaxation. Click AutoScale All. Click Stop to halt the recording. 6. Type Patellar in the Mark box. 7. Click Record and then click the mark button to mark the recording. 8.
