Alice and Bob are have several piles of chips. On each turn they can either remove 1 or 2 chips from one pile, or split a pile into two nonempty piles. Players take turns and a player that cannot make a move loses. Find the value of the Sprague–Grundy function for positions with one pile made of n chips. (Please do not forget to prove correctness of your asnwer.)

Strength of concrete: The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six after pouring. The data are as follows. Can you conclude that the mean strength after three days is less than the mean strength after six days? Let U1 represent the mean strength after three days and ud=u1-u2, Use the a=0.01 level and the critical value method with the table. 1. State the appropriate null and alternate hypotheses....

An experiment was performed to compare the abrasive wear of two different laminated materials. 40 pieces of material 1 were tested by exposing each piece to a machine measuring wear. 100 pieces of material 2 were similarly tested. In each case, the depth of wear was observed. The samples of material 1 gave an average (coded) wear of 85 units with a sample standard deviation of 4, while the samples of material 2 gave an average of 81 with a...

Concrete is a composite material. From microscopic point of view, it can be considered as a three-phase composite with aggregate, cement paste and interface zone between these two components. 1. For concrete with 28-day compressive strength of 35 Mpa (5076psi) made with ordinary Portland cement and crushed granite aggregate, which phase of the concrete is generally the weakest? 2. If the granite aggregate for the concrete mentioned in (i) is replaced by lightweight aggregate. How would this affect the strength...

Can you further compare and contrast two different diagnostic tools presented from our textbook for this week that you would wholeheartedly believe would work well on managing change within your certain kind of business, industry and/or organization? Are these the best tools for your organization and/or industry? Can you further elaborate with any kinds of examples catapulting, trumpeting areas of concern based on the diagnostic tools coursework?

Materials are subject to changes from temperature. We know there are several states of matter: solid, liquid, gas, and plasma. However, within a solid-state, materials have their properties affected, in particular brittleness. The Liberty ships of the Second World War were often breaking from cold weather. These failures highlighted a material fracture problem. What causes these failures, what materials are affected, and are there any that are not? How is brittleness calculated and measured (types of measurement) and what does...
