!!!!GENERAL!!!! a mod b = a - b * floor(a/b) x dBm = 10^(x/10) mW 10log(10 (mW) ) = 10 dB
!!PHY 2!! VARIABLES: P_r = Receiving power (W/mW) P_T = Sending power (W/ mW) G_T = Sending antenna gain G_R = Receiving Antenna Gain H_T = Sending antenna height (m) H_R = Receiving Antenna height (m) d = transmission distance (m) λ = c/f = wavelength (m) f = frequency (Hz) c = Speed of light = 3 * 10^8 (m/s) d_break = break point distance (m) N_T = number of transmitting antennas N_R = number of receiving antennas v = velocity (m/s)
Free space Path Loss (Friis Equation): P_R = P_T * G_T * G_R * (λ / (4πd))^2 unit antenna gain is 1. (IF isotropic antenna (theory) P_R = P_T * (c / (4πdf))^2 )
P_r / P_t = Total Path loss (db) TWO RAY: Time between

Gradient: \nabla f = \langle f_x,\ f_y,\ f_z\rangle Directional derivative (unit vector u): D_uf = \nabla f\cdot u Unit direction from A→B: u = \frac{B-A}{\|B-A\|} Tangent plane to z=f(x,y): z - z_0 = f_x(x_0,y_0)(x-x_0)+f_y(x_0,y_0)(y-y_0) Critical points: Solve f_x=0, f_y=0. D = f_{xx}f_{yy} - (f_{xy})^2 Min if D>0,f_{xx}>0. Max if D>0,f_{xx}<0. Saddle if D<0.

General double integral: Type I (y inner): \int_a^b \int_{g_1(x)}^{g_2(x)} f\, dy\, dx

Type II (x inner):

\int_c^d \int_{h_1(y)}^{h_2(y)} f\, dx\, dy

Polar:

x = r\cos\theta,\ y=r\sin\theta,\ dA=r\,dr\,d\theta

Circle: 0\le r\le R.

Line y=mx → \theta=\arctan m.

Region must be continuous in θ.

Cylindrical:

x=r\cos\theta,\ y=r\sin\theta,\ dV=r\,dz\,dr\,... Continue reading "Multivariable Calculus and Vector Analysis Formulas" »

Chapter 18: Current & Accumulated E&P (CEP & AEP)

(TI ± its Adjustments = CEP) CEP is determined on the last day of the tax year, before calendar year distributions. Example: AEP = 20,000; Loss = 25,000; distribution = 10,000 on July 1. CEP at 7/1 = (25,000) × 1/2 = (12,500). Net = (12,500) + 20,000 = 7,500 taxable dividend and 2,500 nontaxable return of capital.

Corporate Distributions — Layered Tax Treatment

Corporate distributions are paid out of earnings and profits (E&P) unless otherwise shown, and they occur in layers:

• Earnings and Profits — Taxed as dividend income.
• Stock Basis — Nontaxable return of capital (reduces shareholder basis).
• Distribution in Excess of E&P and Basis — Taxed as capital gain.

E&P is... Continue reading "Corporate Taxation: Earnings & Profits, Distributions, 351, Partnerships" »

I. Reflex Activity: Definition and Physiology

• Reflex Definition: An involuntary, automatic response to a peripheral stimulus, involving either motor or secretory action.
• Function: Crucial for adaptation to internal and external changes.
• Dependence: Requires the integrity of the reflex arc; disruption at any level abolishes the reflex.

II. The Reflex Arc: Components

The reflex arc consists of five essential components:

1. Receptor Organ: Transforms a stimulus into nerve impulses.
2. Afferent Neuron: Conducts the impulse to the Central Nervous System (CNS).
3. Integration Center: Typically located in the spinal cord or brainstem; processes signals via synapses.
4. Efferent (Motor) Neuron: Sends the command from the CNS to the effector.
5. Effector: The muscle or gland

1. Brain Abscess

• Gross Morphology

  Localized area of liquefactive necrosis filled with yellow pus, surrounded by a thin fibrous capsule and edematous, inflamed brain tissue.

• Pathology

  Caused by hematogenous spread of bacterial infection, direct trauma, or contiguous spread (e.g., from sinuses). Represents focal suppurative inflammation of the brain.

2. Neurinoma (Schwannoma)

• Gross Morphology

  Well-circumscribed, encapsulated globoid mass with a soft, tan “fish-flesh” appearance, often with cysts or hemorrhage. Cut surface may show yellow patches.

• Pathology

  A benign tumor of Schwann cells, often seen in cranial nerves (especially CN VIII) and associated with neurofibromatosis type 2. Grows slowly and may compress adjacent structures.

3. Fibrinous

Article 12: Defining "The State"

Key Principles of Article 12

• Inclusive Definition: Encompasses Government, Parliament, State Legislatures, local authorities, and other authorities.
• Purpose: Defines entities bound by Fundamental Rights in Part III of the Constitution.
• Judicial Evolution: Interpretation has evolved from narrow to broad.

The "Other Authorities" Test

Pradeep Kumar Biswas Test (2002)

• Focuses on Deep & Pervasive Control (DPC).
• Requires examination of cumulative facts showing financial, functional, and administrative domination.
• Control must be pervasive, not merely regulatory oversight.
• Refines the Ajay Hasia factors, emphasizing control.

Structuralism vs. Functionalism Debate

• Structuralism: Emphasizes formal links and control focus (dominant

Money and Monetary System

• Money: An asset that serves three functions: medium of exchange, store of value, and unit of account.
• Fiat Currency: Money issued by a government with no physical backing (e.g., euro, dollar).
• Fiduciary Currency: Money based on trust, not intrinsic value (e.g., Bitcoin, checks).
• Ledger: An accounting record showing debts and transactions.
• Unit of Account: Allows expressing the price of goods/services (e.g., a coffee costs €2).

Cryptography

• Hash: A mathematical function that converts data into a unique and irreversible digital fingerprint.
• Asymmetric Cryptography: Uses a pair of keys (public and private) to encrypt and decrypt messages.
• Digital Signature: Proves that a message was sent by a specific user and has not been modified.
