LITTLEFIELD LABS ANALYSIS Global Strategy Since the beginning the team decided to try an aggressive strategy to win the game‚ assuming a riskier position with higher potential benefits and costs. For that‚ it was necessary to identify key parameters of the process and design a dashboard to analyze the information and make decisions in a faster way. The key parameters we started monitoring were demand (jobs accepted)‚ stations utilization and lead times of the entire process. The first goal was

Lab 4: Le Chatelier’s Principle Name: Cammey Mahowald Lab Partners: None Date of Experiment: March 16‚ 2015 Course: CHE 112 Abstract: The purpose of this experiment is to understand the components of a reaction at chemical equilibrium and use Le Chatelier’s principle to predict the direction an equilibrium position will shift upon changes in the concentration‚ temperature‚ and pressure. It was determined that in the equilibrium of chromate and dichromate it is an exothermic reaction and in the

Unit 2 Research Paper 1: Experiment A problem that I think needs to be solved is traffic lights causing the back up of traffic. Traffic lights cause a delay in traffic and cause for traffic back up. It causes everyone to be late when there is no need for it. From personal experience I have been late of several occasions due to backed up traffic because of traffic lights. There are certain spots where traffic lights are not needed and they are only backing up traffic more than needed. Traffic lights

Assembly: 1. Set the curing oven to the temperature recommended by the epoxy manufacturer. 2. Follow manufacturer’s instructions for mixing the epoxy. 3. Secure needle to the syringe and load the syringe with epoxy while ensuring it is free of air pockets. 4. Insert the needle tip into the back of the connector until it bottoms out against the ferrule. Maintain pressure and slowly inject epoxy until a bead appears on the end of the ferrule tip and continue to inject epoxy until the bead covers approx. 1/3
