Assuming these measurements L = 100 +/- 0.5 ft and θ = 30 +/- 0.2 degrees, estimate the height H of the building and the uncertainty in the estimate. For the same building height and measurement uncertainties, use Excel’s Solver to determine the angle (and the corresponding distance from the building) at which measurements should be made to minimize the uncertainty in estimated height. Evaluat and plot the optimum measurement angle as a function of building height for 50 < H < 1000 f Solution Given: Data on length and angle measurements. Find: The data provided are: L = 100⋅ ft δL = 0.5⋅ ft θ = 30⋅ deg δθ = 0.2⋅ deg The uncertainty in L is uL = δL L uL = 0.5 % The uncertainty in θ is uθ = δθ θ uθ = 0.667 % The height H is given by H = L⋅ tan ( θ ) H = 57.7 ft For the uncertainty  θ ∂  L ∂ uH =  ⋅ H⋅ uL  +  ⋅ H⋅ uθ   H ∂L   H ∂θ  2 2 and ∂ ∂L H = tan ( θ ) ∂ ∂θ H = L⋅ 1 + tan ( θ ) ( 2 ) so L   L⋅ θ ⋅ ( 1 + tan ( θ ) 2) ⋅ u  uH =…

addressing a real-life problem – how to most efficiently control the elevators or lifts of a building. At the heart of the challenge is an elevator simulator which allows programmers to design, code and then test their implementation in efficiently managing elevators in different realworld scenarios. You also get the chance to test your skills by comparing results with others, including the option to submit results here to compete against other programmers from around the world. The…

Parsons Copyright & 2000 John Wiley & Sons Ltd Print ISBN 0-471-98857-X Online ISBN 0-470-84152-4 Chapter 7 Other Mobile Radio Channels 7.1 INTRODUCTION A great deal of attention has been given to propagation in built-up areas, in particular to the situation where the mobile is located in the streets, i.e. when it is outside the buildings. It is apparent, however, that other important scenarios exist. For example, hand-portable…

original height of 145 meters, its total weight was originally about 6,000,000 tons, consisting of 1 million stone blocks mounted over 20 years. Coated with marble (which was worn and / or removed over time) and a block of shiny metal (gold or a mixture of gold and silver) at its peak, the Kéops pyramid was surrounded by a complex of structures that included smaller pyramids for their queens and nobles mastabas to his court. After Kéops, pyramids continued to be built for over a thousand…

completely cure, and the more it cures the stronger the structure becomes. • When the process is complete it is much like constructing a hand made wall of solid rock. HISTORY & ORIGINS • Rammed earth technology has been around for thousands of years, as an ancient sustainable construction material, used to form monolithic walls. • Long sections of the Great Wall of China, and famous buildings such as the Alhambra in Granada, and the Potala Palace in Lhasa are built in rammed…
