Task Requirements  Write a report about the following case study (see the description below).  Word limit: minimum of 5,000 words and maximum of 10,000 words (excluding the reference list)  Referencing style: APA6 or APA7  Submission: Thursday, 20 Oct 2022 Case study description Gecko Allied Health Services (GAMS) Standards in community health care are steadily rising. A recent development is value-based health care delivery where greater attention is focussed on the patient. This has resulted in the traditional “silos” of health care delivery being broken down so that medical services are delivered by a multi-disciplined group of doctors and allied-healthcare professionals. There is further pressure to extend this model into the community so that access to these specialised models of health care delivery is not limited by the location of where people live. The purpose of this assessment exercise is to develop a comprehensive set of documentation that reflects the three aspects of McCabe’s approach to network design: analysis, architecture and design. Please refer to the marking criteria.

A railway embankment is to be built on a profile of soft clay in an estuarine environment of NSW. The ground surface is at elevation +2m AHD (AHD: Australian Height Datum) and the top surface of the embankment should be at elevation +4m AHD. The initial design put forward by a geotechnical engineer is a 2m high embankment, 7m crest to crest, with 2H:1V batter slopes. The bulk density of the embankment is estimated to be 1.78 t/m³. The soil profile consists of 50 m of soft clay overlying some dense sand. Some soil specimens were collected and tested returning the following values: m = 2.5 MPa ¹, Poisson's ratio of 0.3, Gs=2.65, c, = 14m²/y. The objective of this assignment is to compute the settlement under the centreline of the embankment using different assumptions and models and evaluate the different results. Plane strain conditions can be assumed. 1- Under the centreline, what are the deformation conditions (i.e. 1D, 2D, 3D)? 2- Plot the increase of vertical stress and horizontal stresses under the centreline of the embankment, due to the embankment. Plot stresses from the surface to 50m, in 1 m increment. The plot should look like sin r plots of tutorial solutions. For this question, produce all steps of calculation at a depth of 5m and plot the rest of the stress values. 3- Assuming 1D conditions (i.e. no lateral deformation, no stress dissipation), compute the primary consolidation settlement under the centreline. Discretise the soil into sub-layers if you deem it necessary. Comment your result. 4- Using the SB method, compute the primary consolidation settlement of the embankment under the centreline for: a. No discretization of soil profile: b. Discretization of the soil profile into 2 sub-layers of thickness c. Discretization of the soil profile into 5 sub-layers of thickness d. Discretization of the soil profile into 10 sub-layers of thickness e. Discretization of the soil profile into 20 sub-layers of thickness For each discretised profile, compute the stress at the appropriate depth(s). 5- Compute the primary consolidation settlement of the embankment under the centreline following the method of the lecture notes, i.e. 1D in the confinement triangle + the SB method outside. 6- Conclude on your findings in terms of the effect of discretization on the settlement value, choice of model, effect of assumptions made, magnitude of settlement. 7- Using the result of question 5, compute and plot the evolution of primary consolidation settlement in time from t=1year to t90, in 5 years increment in between (1, 5, 10, 15 etc...).

6) A sphere of radius R, made from a material of specific gravity SG, is submerged in a tank of water. The sphere is placed over a hole of radius a in the tank bottom open to the atmosphere, as shown in the diagram below. Assume a is much smaller than R. a) Develop a general equation for the range of specific gravities for which the sphere will float to the surface. b) For the values given, determine the minimum SG required for the sphere to remain in the position shown.

Calculate the volume of the can. Create a question involving a real-world application that can be solved by the sine or cosine law. Draw a triangle that represents the situation and solve the triangle. Draw a perspective drawing of an item that you would find in your home.  Task 3: Communication questions Imagine you have decided to design an item of furniture for your home. Name the item you wish to make. Describe the size of the item. Why have you chosen this size? Describe the shape of this item. What geometric shapes will this item include? Describe the material you will use. What advantages do these materials have over others? What are some unacceptable materials for this item? Are there any standard requirements related to this item? Explain.  Discuss some of the other constraints associated with this item. A cardboard box is being designed to hold a volume of 729 cubic cm of salt What dimensions would you recommend for the box?

A FAILURE X R&M Machinery had for years provided XYZ with sophisticated equipment and reliable repair service. XYZ returned a failed piece of equipment. A meeting was held which included Archie Hunter, a representative from XYZ; Norm Nash, R&M's returned goods area representative, and, Walt Winters, an R&M engineer intimately acquainted with the kind of equipment XYZ had returned. Norm Nash represented R&M's "official position": the piece of equipment is all right. However, during the course of the meeting it becomes apparent to Walt Winters that the problem has to be R&M's. He suspects that the equipment was not properly tested out by R&M, and that it failed because of an internal problem. Should Walt say anything about this in the presence of the customer, or should he wait until after the meeting to discuss this with Norm Nash? II Walt keeps silent during the meeting. After the meeting he talks with Norm about his diagnosis. He suggests they tell XYZ that the problem is R&M's fault, and that R&M will replace the defective equipment. Norm replies, "I don't think it's wise to acknowledge that it's our fault. There's no need to hang out our wash and lessen XYZ's confidence in the quality of our work. A 'good will' gesture to replace the equipment should suffice." R&M management decides to tell XYZ that they will adjust to the customer's needs "because you have been such a good customer all these years." Although R&M replaces the equipment at its own exprense, it does not tell XYZ the real nature of the problem. 1 Discuss R&M resolution of the problem. Should R&M's way of handling the problem be of any concern to Walt Winters at this point, or is it basically a "management problem"? III Many engineers eventually move into management positions. If Walt Winters moves into management, what lessons, if any, might he take with him from the above situation? [Prepared with James Jaksa.]
