Applying Integer Linear Programming to the Fleet Assignment Problem ABARA American Airlines Decision Ti’chnohi^ics PO Box 619616 Dallasll’ort Worth Airport‚ Texas 75261-9616 We formulated and solved the fleet assignment problem as an integer linear programming model‚ permitting assignment of two or more fleets to a flight schedule simultaneously. The objective function can take a variety of forms including profit maximization‚ cost minimization‚ and the optimal utilization of a particular

Uniform Velocity (straight line) motion – UVM 2. Simple Harmonic Motion – SHM 3. Uniformly Accelerated motion (Parabolic Motion) – UAM or PM 4. Modified Uniform-Velocity Motion – MUVM a. Arc method – MUVM-Arc b. Uniform Acceleration Method – MUVM-UAM 5. Cycloidal Motion – CM A. Uniform Velocity Motion (Straight Line Motion) If the follower is to move with uniform velocity‚ its displacement must be the same for equal units of time.

we want it to detach on our way back and used winglets because it makes best landing‚ they are light‚ and they will not band or fall off. After that we added decoupler to the bottom of our rocket. Then we moved three radial decouplers one stage up and moved liquid engine one stage down. So if we detach the rocket the wings will not fall off and engine would be already activated. Next we added tri-coupler and to that we stacked three sets of fuel tanks and underneath that we put LV-T45 liquid engine

The Blue Machinery of Summer – Yusef Komunyakaa The central conflict is that he does not feel the same since he has come back from Vietnam. I would say there are two instances that he best describes this problem. "I still hadn’t told her I felt I’d left part of myself in her country." (88) Another moment was at the very end when he imagines the faces of the dead from Vietnam on his way to L.A. I think that the whole story builds up suspense by the way he dances around the problem and never talks

Homer has a hard time keeping his morals in perspective as his father discourages him to work on the rockets‚ making him even more determined to succeed. At the same Homer is trying to gain the confidence to follow his goals despite his father’s requests. Choice of Freedom Homer’s opportunity for freedom starts on October 4‚ 1957‚ while he sits watching

the town of Coalwood is destined to become coal-miners‚ unless they are lucky enough to get a football scholarship. To everyone coal-mining was Homer’s only future‚ just like his father. Homer and his friends fearlessly begin learning how to build rockets and testing them. The whole town is not behind them and believe they’re wasting their time‚ especially Homer’s father John Hickam. The only one who strongly supports them is their teacher‚ Miss. Riley. She tells them that they can contend in The National

The independent variable is the amount of baking soda. The dependent variable is how far the rocket launches.

The angle through the merry-go-round has turned varies with time according to θ(t) = γt + βt3‚ where γ = 0.400 rad/s and β = 0.0120 rad/s3. a. Calculate the angular acceleration as a function of time. b. What is the initial value of the angular velocity? c. Calculate the instantaneous value of the angular velocity at t =5.00 s and the average angular velocity for the time interval t = 0 to t = 5.00 s. 2. At t
