System analyzes the request and estimates the last known location of the cable. e. The system uses a magnetometer to detect the cable. f. System successfully locates the underwater cable. c) Exceptions a. There are no active requests within the designated area. The system will be utilized elsewhere. b. Another underwater cable has errors and takes priority. d) Post Condition: The underwater cable is located successfully. 2) Name: Request for AUCIV deployment is created. e) Preconditions/Triggers: The cable company is completing annual inspections and needs access to the system. f) Main Success Scenario a. The maintenance request is scheduled with required information. b. The system is deployed from the mothership. c. The junction boxes provide voltage and current of cables to find the fault. d. The system is dispatched to the correct location of the fault. e. The system examines the cable for visible external damage. f. The system interfaces with the junction box to determine the throughput and connection. g. The system will transmit the location of the fault to the mothership connection. g) Exceptions a. The communications network is down and the system unable to receive request updates. b. The previous inspection data is validated, and no new inspection needs to be done. h) Post Condition: The underwater cable inspection is completed. 3) Name: Request for data processing to be completed. i) Preconditions/Triggers: After the system gathers and stores data, it needs to process and analyze the data to be presented. j) Main Success Scenario a.

I) Post Condition: All data has been loaded into the central data center. Question 2 (5 pts): Conduct a gap analysis of your project problem. List 5 gaps that are applicable to your project. Quantify the existing capability (you may have to do some research, and cite your sources), remember to include metrics. Then identify the desired capability that would sufficiently address your project scope, remember to include metrics; they should be the same units as the existing capability. Quantify the difference between the existing and desired capability. 1. The system that handles inspections contains human error. The current system utilized to complete inspections is a human diver visually inspecting the underwater cables. Due to the use of the human eye, there contains an aspect of human error is mis-diagnosing faults or missing them entirely. As the majority of divers are not engineers or technicians and cannot fully understand the faults they are viewing and may assume there is no issue in some cases. Divers can be trained to know signs of faults, but it is perceived differently underwater. Another take on the human error is elaborated by "In Bierens 'Drowning: Prevent, Reduce and Treatment' (section 175.2.6) (1) he states "A thorough investigation usually reveals a critical error in judgement, the diver going beyond his or her level of training and experience, or a violation of generally accepted safe diving practices. In other words, the root cause is most commonly 'diver error"". [1] How the human error is not on the inspection alone but on the diver themselves. This can result in possible fatalities of the diver and a slowdown on the overall mission as everything would need to be halted. 2. The system that completes inspection has limitations in the human body. The current system utilizes human divers to complete the inspections, however, the human body has limitations it can take when submerged under water. A prerequisite of a human diver is to have a healthy heart and respiratory system, which requires standard medical checkup limiting the divers who pass the prerequisite. [2] An article states "Your heart thus takes in an additional 6 to 8 ounces (180 to 240 milliliters) of blood, resulting in an enlargement of all four chambers, an increase in pressure in your right atrium, a more than 30-percent increase in cardiac output and a slight increase in your overall blood pressure." This is why it is so important for the diver to have a healthy body to be qualified as an inspector. As well as, when submerged a diver will lose more body heat than if on the surface, as the water has a high thermal conductivity. While diving the human body can deep dive starting at 18 meters to 200 meters, with an estimated time of 12 hours spent underwater. However, they are required to take long decompression stops to prevent any issues to the body. [3] An article states "A 1996 paper in the journal Medicine & Science in Sports & Exercise showed that wearing just one scuba tank may increase a diver's energy consumption by 25 percent over regular surface swimming at the same speed and that using a drysuit may result in another 25 percent increase in energy consumption." [2] A diver needs to be physically fit to complete an inspection but also know their body's limitations. They would need to be able to pass an exercise stress test at 12 METS which is equivalent to about 60 minutes of intense exercise. [2] 3. The equipment used for inspections has limitations in the amount of air it contains. The equipment that divers utilize has a limitation on the amount of air which can be used during the dive. A scuba tank can last up to 30 minutes of air when not in use. A standard 80-cubic-foot scuba tank can hold 20-30 minutes of breathable air before it needs to be replenished. A standard tank filled with compressed air will contain 20.9% oxygen with the rest being nitrogen and helium which make up 99% of the air on Earth. [4] Depending on the circumstance, the tank may contain a different percentage of oxygen. Currently, an average scuba tank can weigh up to 6.5 lbs. and hold compressed air at 3,000 psi pressure. [4] However, the scuba tank is affected by direct sunlight and/or heat which can damage the composite filled with air. Therefore, the tanks need to always be monitored to ensure they are in a sheltered, cool location. Also, compressed air can only be high-quality from a reputable source which needs to be part of the mission schedule and trained personnel would need to be allocated for that. 4. The system that completes the inspections relies on good weather conditions and cannot complete mission in bad weather. The use of human divers creates an aspect of human safety which needs to be observed constantly. An inspector would not be able to go underwater if there is bad weather currently or planned during the time of the inspection. The human divers would have to schedule inspections around the weather which can affect the schedule timing and cost. 5. The time to complete the system affects the performance and cost of the inspection. The current use of human divers is perceived as slow since they are reliant on the equipment and accurate location of the cable. A diver can stay underwater for no more than 1-2 hours before they need to come up for a regular break to prevent any damage to the human body. [5] However, a diver cannot repeat the process of submerging for a couple hours and then resting, then submerging again. A diver inspection would take days and require the use of multiple personnel for every aspect of the inspection and the boats to hold these personnel. This affects the time of the inspection negatively and overall causes issues with the cost being higher than necessary. Sources: [1] Lock, Gareth.
