Discuss the features of the beamformer response and provide a physical explanation for the performance.
Assume you have to use the array from the previous problem in an isovelocity (1500 m/s), shallow water environment with water depth 120 m, and with an infinitely rigid bottom. Assume you are towing the array at 60-m depth, and that the source is at 60-m depth as well. a. For a 10-Hz source at […]
What happens at the position of the original point source
For an acoustic field in a waveguide, how would you take advantage of the orthogonality of normal modes to construct a modal, rather than plane-wave beamformer? Use a vertical array. 1. Write down an expression in terms of discrete normal modes for the field of a point source received on a vertical array. Take the […]
What is a timeout and how is it used in service failure management?
1. What is a timeout and how is it used in service failure management? Explain why a circuit breaker is a more efficient mechanism than timeouts for handling external service failures. 2. Explain what is meant by a “resource.” How do RESTful services address resources and operate on them? 3. Consider the Upload service for […]
identify elements of a contents list and mark these up at different levels.
Imagine that your software includes a feature that can automatically create a contents list for a document or book. Suggest tests that you might develop to test this feature. It is described by the following user stories: a. As auser, I want to automatically create a contents list for my document that includes all of […]
