Understanding Market Elasticity: Demand, Supply, and Income Effects
Elasticity: Definition and Concepts
Elasticity measures the percentage change in quantity demanded or supplied in response to percentage variations in other dependent variables (such as price or income). When analyzing supply and demand curves, elasticity is present at each and every point. A curve is said to have constant elasticity if the value remains the same across all points.
Price Elasticity of Demand (PED)
The Price Elasticity of Demand (PED) measures the percentage variation in quantity demanded

Understanding Key Events and Concepts of World War I
Photo of the Map: What is the map representing? Plan Schlieffen – What was its main objective? Occupy France quickly through Belgium – Was it a success? Why? No, because it took much longer than expected and the Germans couldn’t occupy France. Photo of the Ship: What is the picture representing? The sinking of the Lusitania – What was the objective of that ship? The Americans sent supplies to help the Triple Entente – What was the consequence of that situation? The intervention of the USA.

- Mahayana

Four Noble Truths
- Life is suffering.
- The cause of suffering is desire.
- To overcome suffering, we must overcome desire.
- The path to salvation is the Noble Eightfold Path.
Four Signs Siddhartha Saw
- Old age – everything is going to change.
- Sick person – everyone suffers, and nothing can change that.
- Corpse – nothing is permanent.
- Ascetic – renounces material possessions, learns that there is hope and a chance to break suffering.

Understanding Independent Component Analysis and Particle Filters
Independent Component Analysis (ICA)
ICA is a statistical technique used to separate a multivariate signal into independent, non-Gaussian components. It assumes the observed data are linear mixtures of independent source signals.
Mathematically, X = A S
where X is the observed mixed signals, A is the unknown mixing matrix, and S is the statistically independent source signals.
The aim is to estimate A and S such that S = W X, where W is the separating matrix.
Steps in ICA
- Centering: Subtract mean to make
Understanding Adaptive Passive Vibration Absorbers and AVC Systems
Adaptive Passive Vibration Absorber (APVA) & Methods: An Adaptive Passive Vibration Absorber is a device that reduces unwanted vibrations in machines or structures. Unlike normal (fixed) passive absorbers, an APVA can adjust its own properties — such as mass, stiffness, or damping — to work effectively even when the vibration frequency changes. It does not require active control or high power, so it is still considered passive, but it can adapt automatically or semi-automatically to new

Disinfection Principles and Methods
Disinfection is the process of destroying or inactivating disease-causing microorganisms (pathogens) from objects, surfaces, water, or the environment, so that they cannot cause infection.
Properties of an Ideal Disinfectant
- Broad-spectrum.
- Rapid action.
- Non-toxic to humans and animals.
- Stable in storage.
- Works in the presence of organic matter.
- Economical and easy to use.
Types of Disinfection
1. Physical Methods
- Heat: Boiling water, steam under pressure, dry heat.
- Radiation:
Understanding Environmental Problems and Their Impact
Environmental Problems
Environment: is everything that affects living organisms.
Ecology: is the biological science that studies the relationship between living organisms.
Environmental problems include:
Ozone depletion, acid rains, and smogs.
Ozone (O3):
– Highly reactive gas – harmful to breathe – 3 atoms of oxygen.
1- 90% of the O3 is in the stratosphere, and it is called the ozone layer.
2- O3 absorbs a band of ultraviolet (UV) radiation called UVB.
Ozone Layer (O3):
– A region of Earth’s stratosphere
Understanding Logistics: Key Objectives and Functions
The importance of effective logistics management includes reducing costs, increasing efficiency, controlling inventory, and improving customer satisfaction. A business with a strong logistics strategy can gain a competitive advantage by delivering products to customers on time and in the right condition.
Operational objectives of logistics are often summarized by the “Seven Rs”:
Getting the right product.
In the right quantity.

Engineering Reliability Design Principles
Reliability design ensures that a system or component performs its intended function without failure for a specific period under stated conditions. It is a crucial part of engineering design used in manufacturing, electronics, software, and mechanical systems.
The goal is to minimize the probability of system failure by improving component quality, redundancy, and fault tolerance. Reliability can be expressed as $R(t)=e^{-\lambda t}$, where $\lambda$ is the
