If the Fermi energy of a silicon sample is uniformly 0.2 eV below the conduction band,
calculate:
a. Electron and hole densities
b. Doping concentration
Assume the bandgap is 1.12 eV, at room temperature and the effective density of states, Nc, is
2.86 x 1019 cm-3 and intrinsic carrier concentration is 9.65 x 109 cm-3.

Consider the following difference equation
(E^2+E+1/4)y(k)=sin(kpie/2)
with y(0)=0, y(1)=1
and Find the complete solution to the difference equation

Use the following tree to indicate the order that nodes are expanded, for Uniform-cost search and greedy best-first searches. Assume that A is the start node and G (color box) is the only goal node. Here, path costs are shown to the right of each path.
g = cost of path so far, h = estimate of remaining cost to goal, f = estimate of total path cost (evaluation function).

There are two main types of bones:

Long bones: These are long, narrow bones that are found in the limbs, such as the femur and humerus. They are composed of a shaft, called the diaphysis, and two ends, called the epiphysis.

Flat bones: These are thin, flat bones that are found in the skull, ribs, and sternum. They provide protection for vital organs and serve as attachment points for muscles.

Bone tissue is constantly being remodeled through the process of bone turnover, in which old bone tissue is broken down and new bone tissue is formed. This process is regulated by hormones such as parathyroid hormone and calcitonin.

There are also two main types of bone cells:

- **Osteoblasts:** These are bone-forming cells that are responsible for the creation of new bone tissue.

- **Osteoclasts:** These are bone-resorbing cells that are responsible for the breakdown of old bone tissue.

Bones also have the ability to heal themselves when they are fractured. This process is facilitated by the formation of a blood clot at the site of the fracture, which provides a foundation for the growth of new bone tissue.

Overall, bones are complex and dynamic structures that play a vital role in the functioning of the human body. Their integrity is essential for the maintenance of our posture, movement, and overall health.

Seven measurements of the pH of a buffer solution gave the following results:
5.12 5.20 5.15 5.17 5.16 5.19 5.15
Calculate (i) the 95% and (ii) the 99% confidence limits for the true pH.
