COMPLETE 5 OUT OF 7 QUESTIONS

 

 

Question 1

Consider an airplane with the following Air Data measurements: Static Pressure: 50779 N/m2, Total Pressure: 53175 N/m2, Temperature: 260 K. The reference surface pressure at the nearest airport is 0.974×105 N/m2.

a) Calculate the aircraft’s QFE altitude

b) Calculate the aircraft’s true airspeed

Question 2

VOR A is located at (0, 40 nmi) and VOR B is located at (50 nmi, 0) in a local-level Cartesian coordinate frame. An aircraft measures a bearing of 120 deg from VOR A and a bearing of 315 deg from VOR B. Find the coordinates of the aircraft.

Question 3

A GPS user is located at 39.21°N Latitude, 82.23°W Longitude, and 205 m height (ellipsoidal). The GPS receiver tracks PRN 18 that has an elevation angle of 22° relative to the user. The L1 pseudorange measurement is 23516280 m, and the L2 pseudorange measurement is 23516295 m. Use the following constants: c=299792458 m/s, fL1 = 1575.42 MHz, fL2 =1227.60 MHz

a) Calculate the troposphere delay for the PRN 18 measurement

b) Calculate the ionosphere delay for the PRN 18 measurement

Question 4

At a given moment in time, a GPS receiver determines the following:

inv(H’*H) = [0.4000 -0.3068 0.1068 0.2035; -0.3068 1.2733 -0.7288 -0.7649; 0.1068 -0.7288 1.0288 0.6599; 0.2035 -0.7649 0.6599 0.6573]

a) Determine PDOP b) Assuming the errors on all the satellite measurements are independent white Gaussian

noise with a standard deviation of 2 meters, determine the standard deviation of the 3-D positioning error.

 

 

Question 5

A ‘pseudolite’ is a ground-based transmitter that radiates GPS signals. A major problem associated with their use is the so-called ‘near-far’ problem. Specifically, free-space loss causes a much larger variation in received signal power (as a function of changing receiver position) than for space-based transmitters. Assume a pseudolite is located at an airport and is radiating an EIRP of 1 mW. Further assume the receiver on an aircraft is connected to an isotropic antenna. Approximate the GPS L1 wavelength as 0.19 m.

a) Calculate the power received (in W) if the aircraft is 1 km from the pseudolite

b) Calculate the power received (in W) if the aircraft is 20 km from the pseudolite

c) Calculate the power variation by calculating the ratio of the two received powers in dB

Question 7

The following measurements are obtained from a stationary Inertial Measurement Unit in the

aircraft body frame: 𝐴 = 1.7035 −0.8420 −9.6242

𝑚/𝑠!

a) Calculate the aircraft roll angle in degrees (round to the nearest degree)

At some point in the middle of a flight, the INS has determined that the aircraft-to-platform transformation matrix is:

[ 0.9254 -0.3265 0.1924; 0.3368 0.9413 -0.0227; -0.1736 0.0858 0.9811]

b) Calculate the aircraft pitch and yaw angles in degrees (round to the nearest degree)

Question 6

Consider a DME/P signal that is contaminated with specular multipath with a multipath-to-direct ratio of -10 dB. The DME/P interrogator uses a DAC circuit with a delay of 100 ns and attenuation of 6 dB. Assume the interrogator does not apply any RF filtering that changes the shape of the pulse.

a) What phase of multipath (relative to the direct signal) will cause a peak positive error?

b) Calculate the time delay of the multipath that will cause the peak positive error c) Calculate the peak positive error

SOAP NOTE

 

Academic Clinical SOAP Note

Academic clinical SOAP notes provide a unique opportunity to practice and demonstrate advanced practice documentation skills, to develop and demonstrate critical thinking and clinical reasoning skills, and to practice identifying acute and chronic problems and formulating evidence-based plans of care.

Develop a hospital follow-up progress SOAP note based on a clinical patient from your practicum setting. In your assessment, provide the following:

· A one-sentence description of the primary working diagnosis, pending differential diagnoses, and the context or service in which the patient is being seen.( Acute Care Hospital)

· A one-to-two paragraph description of the current illness or hospital stay, including pertinent diagnostic findings or procedures. Include how many days the patient has been hospitalized, if applicable.

· List of at least five systems affected by the working diagnosis. Provide two positive or negative effects that the working diagnosis has on each system.

· List of at least five systems examined within the last 24 hours. Provide at least two pertinent positive or negative findings relevant to each system examined and include a full set of vital signs.

· List of all admission diagnostics conducted for this visit or conducted within the last 24 hours.( (CPT codes)

· List of all pertinent acute and chronic diagnoses in order of priority using ICD-10. Identify any differential diagnoses being eliminated.

· Treatment plan that corresponds with the diagnosis. Provide information on admission type, types of diagnostics, any prescribed medications and dosages, and any relevant consults or follow-up procedures needed.

· Discussion of any relevant ethical, legal, or geriatric-specific considerations.

Incorporate at least 3-5 peer-reviewed articles in the assessment or plan. (Minimum 1200 words).

Don’t Forget to include all coding including ICD-10, CPT and all others.

While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.
