Q3:3. PROJECT The project will be a very important part of the course. Sample topics include human factors and applications in healthcare, patient safety and telemedicine, transportation, computer, robotics, mechatronics, manufacturing, and service industries. The project will start with literature dealing with a specific aspect of human factors problems. The project report must include the following sections: 1. Introduction and Motivation 2. Literature review 3. Research methods 4. Data Analysis and Results 5. Discussions and Conclusions 6. References Project phases: During the semester, you need to present and submit the report for three phases: Phase 1 project proposal, Phase II project progress, and Phase III final project. Phase I project proposal: you are required to define the research question/issue, supported by reviewing recent literatures. You should finish the Introduction and Motivation. Literature Review, and your plan of Research Methods, Each team is required to submit a project proposal (2 pages). Phase II project progress: you are required to finish the third section Research Methods which consists of the 3.1 Participants, 3.2 Experiment Design, 3.3 Measurements, and 3.4 Procedures. The Pilot Testing as the first part of Results also should be completed. In Phase II you will need to present and submit the project progress report (6 pages). Phase III final project: you are required to finish recruiting all subjects and finish all sections. You can separate the Conclusion and Discussion into two sections. It depends on the extent of your project. If your discussion has at least one column to one page, you should separate them into two sections. If it is only half of the column, they shouldn't be separated. The conclusion usually uses non-technical words to summarize your project into 3-5 sentences in one paragraph. The discussion usually discusses the pros and cons, limitations, future works of the project. In Phase III you are required to give a final project presentation and complete the project final report (10 pages). Project Presentation Format and Submission: 1) A 12 min oral presentation should be presented by students for project proposal, project progress, and final project. 2) Your team is required to record and upload the presentation slides and video (in .mp4) on the Discussion Board by the due time. Zoom recording function is suggested to create the video. 3) The Discussions Board section on Canvas is the interaction area we will use. Under each subject entitled "Project Proposal/Project Progress/Final Project Discussion", upload your video by creating a new reply to the subject. 4) You will also comment on other teams' videos in Discussions Board. Each student will need to comment on all other teams' videos in the following 3 days. You may lose points if you do not review and comment on other teams' work. 5) For the final project presentation, each student will evaluate other students' presentation based on an Evaluation Rubrics. Project report You are expected to use the project report template for all report submissions from Phase I- III. The report is cumulative, which you can continue writing on the report of the previous phase. A final report of your project should outline the work done or planned on the project. It should be presented in the form of an IEEE research paper. You are the author of the project, and thus you should include your own interpretation, opinion and recommendations, etc. It is allowed to include figures or quotations from other sources provided that they are properly referenced. Project Report format: Please use the Project Report template for both project proposal and project report. Individual or group projects: For students enrolled in the on-ground section, the course will culminate in a group project, with each team consisting of no more than three members For students enrolled in the online section, you have the flexibility to choose your own individual projects, or form as groups (not more than three members) in the online setting. The course platform will facilitate opportunities to connect with classmates virtually, making it easier to find teammates. Whether you're working individually or in a team, the project aims to synthesize the skills and knowledge acquired throughout the course, offering a substantive evaluation of your grasp on the subje matter.See Answer

Q8: US Steel Tubular Products (USTP) Inc. is in the process of hiring a repair person for a 3-machine processing department. Two candidates are being considered. The first candidate can perform repairs at the rate of 3 machines per hour and earns $25 an hour. The second candidate, being more skillful, receives $35 an hour and can repair 4machines per hour. USTP estimates that each broken machine will incur $60 per hour due to lost production.Assuming that machine breakdowns occur according to a Poisson distribution with a mean of 2 per hour (per working machine) and that the repair time is exponential, which repair person should be hired? (a) (2 points) Define the states, classify the queueing system, draw the state transition rate diagram with the transition rates, given that 2 is the breakdown rate per working machine and µ is the repair rate for the repair person. (b) (3 points) Find the steadystate probabilities for each repair person (unskillful and skillful). (c) (2 points) Determine the average number of broken machines for each case (unskillful repair person and skillful repair person). nts) Determine the average cost per hour for each case and decide which repair person should be hired.See Answer

Q12: Oxygen consumption is an effective way to measure exertion during static muscle contraction. OSHA's preferred order from least effective to most effective abatements in the Hierarchy of Controls is: personal protective equipment; administrative procedures and policies; engineering controls; substitution and elimination The clutter-avoidance principle requires that there should be no space between components. There is good evidence that the Union Carbide disaster releasing methylisocyanategas in Bhopal India due limited alarms and controls was the worst industrial accident in modern history (1900 on). Classroom based training is a near to task performance support intervention. Redundancy should be avoided as much as possible in the design of display and controls. Both aerobic and anaerobic metabolism supply ATP to muscle cells. Fitt's law, which applies to hand, arm and foot movements, uses the Index of Difficulty, which is a ratio of double the movement amplitude divided by the size of the target width (2A/W). Shift work schedule designers need to be aware of how disrupting the natural humantendency to sleep at night and be awake during the day has on employees. The social model reframes disability, stating that the actual environment disables people by its design.See Answer
