The materials used for this lab were filter papers‚ a choice chamber‚ eight pill bugs‚ water‚ and tin foil. The first step of the process is to trace and cut the filter paper so it fits neatly within each side of the choice chamber. Then‚ put water each filter paper and place the damp filter paper into the choice chamber. The damped filter paper causes the pill bugs to not be able to crawl under the paper and therefore disrupting the results. Four pill bugs should be placed on either side and one

Graphical and Simplex Methods of Linear Programming The graphical method is the more popular method to use because they are easy to use and understand. Working with only a few variables at a time they allow operations managers to compare projected demand to existing capacity. The graphical method is a trial and error approach that can be easily done by a manager or even a clerical staff. Since it is trial and error though‚ it does not necessarily generate the optimal plan. One downside of this

BSDS101: Assignment 1: Outline the stages of Walter Rostow’s Linear development theory and discuss the theory’s applicability to the developing world. Introduction: The question of why and how the developing world has since been developing at a relatively low pace has since been interpreted by various perspectives most of which are Euro-centric and highly debatable. A number of theories have since been formulated to explain why the developing countries are lagging behind in terms of their Gross

Linear Variable Displacement Transducer (LVDT): A very basic transducer which is always useful in the field of instrumentation‚ I have studied about this in my college days. Now let me explain about the LVDT with its Principle of Operation and I will explain how it is constructed for its well known operation and you can understand the working of LVDT. Principle of LVDT: LVDT works under the principle of mutual induction‚ and the displacement which is a non-electrical energy is converted into an

Problem Statement My task was to find 3 equations‚ that would give me an answer‚ if I had certain information. The first was to find one that if you knew that there were four pegs on the boundary‚ and none on the interior‚ you could get the area. The second was if you knew that there were 4 pegs on the boundary‚ and you knew how many were on the interior‚ you could get the area. And last‚ if you had the number on the interior‚ and the number on the boundary‚ you could get the area. Process
