Different participants involved in System Development Process.
Expert Solution & Answer
Explanation of Solution
A system development process goes through many stages with the participation of some members. Different participants that are involved in the development of System process and their role is discussed below.
Project Manager: Project manager plays an important role in the system development process. The project manager ensure that all the objectives are met during the development process. He is also responsible with coordinating all people and resources needed to complete the project successfully. The main tasks of project manager include project scope, ensuring project quality, training personnel, facilitating communications, risk management and acquiring necessary equipment.
System Analyst: System analyst hold expertise in analyzing and designing business systems. System analysts continuously interact with stakeholders, users, management, vendors and suppliers to architect the blueprint for the proposed system. Their main role is to analyze the requirements and design the system to meet those requirements.
Programmer: The main role of programmer is to develop programs for the system according to the requirements of their clients or users. They take
Users: Users are the personnel for which system is developed or people who will continuously interact with the system. They play an important role in this process as they interact with the system and use the system.
Stakeholders: Stakeholders make investments for the development of the system and make benefits from the system after its development.
Technical specialists: Technical specialists might include

messages for transmission at different multiple access wireless nodes at times t=0.1, 1.4, 1.8, 3.2,

For the CSMA protocol (without collision detection), indicate which packets are successfully
transmitted. You should assume that it takes .2 time units for a signal to propagate from one node to
each of the other nodes. You can assume that if a packet experiences a collision or senses the
channel busy, then that node will not attempt a retransmission of that packet until sometime after
t=5. Hint: consider propagation times carefully here. (Note: You can find more examples of problems similar to this here B.]

Just wanted to know, if you had a scene graph, how do you get multiple components from a specific scene node within a scene graph? Like if I wanted to get a component from wheel from the scene graph, does that require traversing still?
Like if a physics component requires a transform component and these two component are part of the same scene node. How does the physics component knows how to get the scene object's transform it is attached to, this being in a scene graph?

For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.
