any waste compounds introduced into such waterways will initiate biochemical reactions (such as shown above). Those biochemical reactions create what is measured in the laboratory as the Biochemical oxygen demand (BOD). Such chemicals are also liable to be broken down using strong oxidizing agents and these chemical reactions create what is measured in the laboratory as the Chemical oxygen demand (COD). Both the BOD and COD tests are a measure of the relative oxygen-depletion effect of a waste contaminant

Part 1: Thesis Statement: A turbocharger is an excellent component and can be utilized to improve fuel economy‚ increase overall horsepower‚ and enhance the engine’s towing ability. I developed this thesis by using my knowledge of the different applications turbochargers are used on. Many vehicle manufacturers these days prefer to use smaller displacement engines and add turbochargers in order to produce a vehicle that gets great gas mileage‚ while not sacrificing power. I did not do any research

Separation of a Mixture of Solids I really enjoyed this lab. After reading the introduction I started by making my own flow sheet of how I thought this lab would work. I was reminded about solubility which is defined as the amount of the solute that will dissolve in a given amount of solvent and that the extent to which a substance dissolves depends mainly upon the physical properties of the solvent and of the solute and to some extent upon the solvent’s temperature. With that being said I came

D6T thermal sensor and People Counting Algorithm In this thesis work‚ a new indoor people counting algorithm is created by using Omron D-6T thermal sensor and Raspberry Pi. The sensor periodically generate thermal map of heat emitted in its field of view which is a one dimension array and pass the array to Raspberry for further processing. The people counting algorithm is created in Raspberry Pi by processing thermal map generated by D6T. After processing the number of people indoor is obtained
