Recursive Binary Tree Traversals

Inorder Traversal:

void inorder(struct node *root)
{
  if(root != NULL)
  {
    inorder(root->left);
    printf("%d\t", root->data);
    inorder(root->right);
  }
}

Preorder Traversal:

void preorder(struct node *root)
{
  if(root != NULL)
  {
    printf("%d\t", root->data);
    preorder(root->left);
    preorder(root->right);
  }
}

Postorder Traversal:

void postorder(struct node *root)
{
  if(root != NULL)
  {
    postorder(root->left);
    postorder(root->right);
    printf("%d\t", root->data);
  }
}

Linked List Operations

Search

void search(struct node *head,int key)
{
  struct node *temp = head;
  while(temp != NULL)
  {
    if(temp->data == key)
      printf("key found");
    temp =

Structure of the Atom

Protons, Electrons, and Neutrons

Protons: Equal to the atomic number

Electrons: Equal to the atomic number

Neutrons: Equal to the atomic mass minus the atomic number

Bohr-Rutherford Diagram

Electron shells: 2, 8, 8, 18, 18, 32

Counting Atoms

Example 1: Na₂CO₃

• Sodium (Na): 2
• Carbon (C): 1
• Oxygen (O): 3

Example 2: 4Al₂(CO₃)₃

• Aluminum (Al): 4 x 2 = 8
• Carbon (C): 3 x 4 = 12
• Oxygen (O): 9 x 4 = 36
• Total: 56

Ions and Ionic Compounds

Ions are atoms that have either lost or gained electrons. While atoms are neutral, ions are charged particles.

Ionic Compounds are a combination of a cation (positive ion) and an anion (negative ion), typically formed between a metal and a nonmetal.

Example: Calcium Chloride (CaCl₂)

Calcium (Ca⁺²) has a charge of +2,... Continue reading "Structure of the Atom, Chemical Reactions, and Acids and Bases" »

SCR Construction

A thyristor, or SCR, consists of four P-N-P-N layers and has three PN junctions (J1, J2, J3) in series. It has three terminals: Anode, Cathode, and Gate. The Gate terminal is attached to the P-type layer near the Cathode terminal. The two-transistor model shows that an SCR is a combination of one PNP transistor and one NPN transistor.

The emitter of the PNP transistor is taken as the Anode terminal, the emitter of the NPN transistor is taken as the Cathode, and the base of the PNP is taken as the Gate terminal. The base of the PNP is connected to the collector of the NPN, and the collector of the PNP is connected to the base of the NPN transistor.

Advantages of SCRs:

• Easy to turn ON
• Can handle large voltage, current, and power
• Possible

Robot Kinematics

Euler’s Rotation Theorem

Any rigid body motion that leaves one point fixed can be represented by a single rotation about an axis through the fixed point.

Chasles’ Theorem

Any rigid body motion is the translation of a designated point & a rotation of the whole body about that point.

Kinematic Parameters

These parameters are associated with the kinematic configuration of each link and joint of the robot arm. There are four main kinematic parameters:

Joint Parameters

The relative position and orientation of two successive links can be specified by two joint parameters:

• Joint Angle (θk): The amount of rotation about zk-1 so that Xk-1 is parallel to Xk.
• Joint Distance (dk): The amount of translation along the Zk-1 needed to make

Hedging with S&P 500 Index Futures

SIF hedging: NF = V_F(antiguo) = F_o x Z. NF (Number of contracts) = V_p (portfolio value) / (V_F x B_p) (Beta). With this hedge, risk is removed. If the index goes up, the profit in the portfolio will be offset by losses in SIFs contracts and vice versa.

Example: S&P 500 falls 5%:

• In the portfolio: R_p = B_p x (-5%) = -10% of a portfolio of $10M, resulting in $9M (Final Value).
• In the SIFS contracts: S_i = 980 (S&P 500 value given) x 0.95 (100% - 5%) = 931. F_i = 931 x (1 + 0.04 x 5/12 (next month timeframe)) = 946.52. V_F = NF x (F_i - F_o) x Z (250).
• Gain on futures: V_F(New) / Equity portfolio value.
• Outcome stock portfolio: 2 x (-5%) = -10%.
• Final Value portfolio: $10M - $1M + V_F(New).
