Describe four basic issues that should be considered prior to selection of an evaluation procedure.

Fred and Martina, senior agents at an airline security checkpoint, carry out advanced screening procedures for hundreds of randomly selected passengers per day. For a random sample of 30 passengers recently processed by Fred, the mean processing time was 124.5 seconds, with a standard deviation of 20.4 seconds. For a random sample of 36 passengers recently processed by Martina, the corresponding mean and standard deviation were 133.0 seconds and 38.7 seconds, respectively. Using the 0.05 level of significance, can we conclude that the population mean processing times for Fred and Martina could be the same? Use Unequal-Variances T-Test.

Problem 1 (20%) The Haddon Matrix is a used commonly used, two-dimensional model used to analyze safety through three phases of a crash (pre-crash, crash, post-crash). The matrix provides insight into the range of possible safety issues that may have led to the crash and helps engineers propose appropriate safety countermeasures. Pre-Crash Crash Post-Crash Haddon Matrix Human Vehicle Physical Environment Use the following crash to fill out a Haddon Matrix: A single vehicle crashed on I-84 west in Willington at 1:38pm in March of 2024. The weather conditions for that day were rainy, leading to wet road surfaces and poor visibility. The driver of the 2015 Dodge Charger was speeding when he lost control of the vehicle and crashed into the center median. The vehicle had "disabling damage" and the driver remained on scene until emergency services arrived. Investigators say that the vehicle had "bald tires" at the time of the crash. Additional crash information can be found here:…

Q5/ The structural engineering design section within the engineering department of a regional electrical utility corporation has developed several standard designs for a group of similar transmission line towers. The detailed design for each tower is based on one of the standard designs. A transmission line project involving 50 towers has been approved. The estimated number of engineering hours needed to accomplish the first detailed tower design is 126. Assuming a 95% learning curve, a. What is your estimate of the number of engineering hours needed to design the eighth tower and to design the last tower in the project? b. What is your estimate of the cumulative average hours required for the first five designs?

Indicate whether the following statements are true or false. The quality of a visual inspection is affected primarily by; i) The quality of the detector (eye or camera), ii) The lighting conditions, iii) The capability to process the visual data, iv) The level of training and attention to detail Visual inspection is a very simple and basic method; therefore, it is not considered as one of the commonly employed NDT methods. The two phases involved in applying the maturity method to estimate the in-situ strength of concrete are i) Laboratory testing and ii) Field measurement of the in-place temperature history Optical aids such as mirrors, magnifiers and comparators are often used as a tool of visual inspection. The most popular nondestructive test used on concrete structures is the rebound hammer test. The two parameters needed in the Nurse-Saul Maturity Function is Apparent Activation Energy and Datum Temperature. Visual inspection is simple to perform, low in cost and relatively…

A highway bridge is currently scheduled to be inspected once every two years. There is a 3% probability that during an inspection a major defect will be found. Compute the probability that in the next 12 years no defects will be found in the bridge. Assume statistical independence concerning finding defects in different inspections.

Aim of the coursework Identify and determine the scope of hazardous substances Understanding the risk assessment procedure Develop skills in recognizing hazards Learning Outcomes Identify and differentiate the kinds of hazardous substances. Conduct hazard analysis List simple safety procedures and precautions to save any process. Task: You are expected to carry out a risk assessment in your own college/lab/workshop. Name of assessor – put any name. Date – put any date of the assessment. Time – put any time of the assessment. Work area – briefly describe the work area in terms of function, size, number of floors, number of people. For example: Ground floor warehouse, 900 square metres with up to 50 people. Task being assessed – Be specific, e.g. Use of forklift truck to move goods from loading bay to racking. You need to select FOUR hazards that are not being adequately controlled. Common hazards include: Working at height (e.g. working at height on a ladder 3 metres high) Manual…
