Draw an E-R diagram with all appropriate notation for the following situation. In a particular fruit-growing region there are a number of orchards. Each ORCHARD is identified by its LOCATION. In general, each orchard contains a large number of trees (assume that an orchard must contain at least one tree). A TREE entity has the attributes NUMBER (which is a serial number) and YEAR PLANTED. Each tree is a member of a single SPECIES (for example, apple, peach, and plum are species). A species is identified by a SPECIES NAME. Each species bears one or more varieties. For example, with grafted branches, an apple tree might bear two varieties: Yellow Delicious, and Jonathon. Each VARIETY is identified by a VARIETY NAME. Each variety is borne by exactly one species (thus for example, a Yellow Delicious apple can only be borne by an apple tree.). From the previous discussion, we can infer that each tree has one or more varieties. At a given time, a particular species may not have any trees as members, or have one or more trees. Similarly, a given variety may or may not be represented by trees at a given time.

Solution Summary

This Solution contains an Orchard E-R Diagram graphic.

Consider a (3,1,2) convolutional code with the generator for the encoder, g1 = (101), g2 = (111), and g3 = (111).
(1) Draw the encoder diagram for the encoder.
(2) Draw the trellis diagram for the information sequence (11011).
(3) Suppose the received sequence R = (111,010,000,011,100,011,111); decode R by use of Viterbi algo

Suppose that you have the following data
x 3 5 2 6 1 4
y 25 110 9 250 3 71
a) Draw the scatter diagram. Does it appear that x and y are related? If so, how?
b) Test to determine whether there is evidence of a linear relationship.

S = {0,1} and consider the partial order relation R defined on S X S X S as follows: for all ordered triples (a, b, c) and (d, e, f) in S X S X S.
( a, b, c ) R ( d, e, f ) <-> a ≤ d, b ≤ e, c ≤ f,
where ≤ denotes the usual "less than or equal to" relation for real numbers. Please demonstrate how to draw

A system is defined by the equations:
x1 = -3x1 + 2x2 + x3 + 2u1 + u2
x2 = 3x1 - 2x2 + x3 + u1
x3 = -4x2 - x3 + u1
y1 = 5x1 - 3x2 + x3 + u1
y2 = x1 + x2 + u1 + u2
Write the equations in standard matrix form and identify the A, B, C, and D matrices
Draw a simulation (block) diagram.

First graph - draw the total cost curves (FC, VC, and TC) in ONE diagram. You also need to label all the axes correctly and place the legend at the bottom of your diagram.
Second graph-draw the average cost curves (AFC, AVC, and ATC) plus the marginal cost (MC) in ONE diagram. Label all the axes correctly and place the legend
