As the complex terrain in hilly areas is not conducive to corn mid-tillage precision fertilization, a corn-overlapped strip fertilizer spreader was designed without an external power source. By configuring passive overlapping spreading method with three-branch split chamber structure, uniform of strips achieved. A horizontal and vertical movement model developed determine angle extending tube, ...

Instead of the A/D converter design, you can also choose to work on a design project of your choice. Consult with the instructors about your project topic. This handout gives an introduction to A/D converter characteristics, testing, and A/D converter types. Characteristics common to all types of A/D converters are discussed in Section 1, together with a test circuit that can be used to verify ...

In conjoint experiments, each respondent receives a set of profiles to rate. Sometimes, the profiles are expensive prototypes that respondents have to test before rating them. Designing these experiments involves determining how many and which profiles each respondent has to rate and how many respondents are needed. To that end, the set of profiles offered to a respondent is treated as a separa...

In the common linear regression model we consider the problem of designing experiments for estimating the slope of the expected response in a regression. We discuss locally optimal designs, where the experimenter is only interested in the slope at a particular point, and standardized minimax optimal designs, which could be used if precise estimation of the slope over a given region is required....
