Essential Marketing Concepts: Pricing, Promotion, and Strategy
Understanding Pricing Structures and Strategies
Companies do not set a single price but utilize a pricing structure.
A pricing structure means a company sets different prices for different segments, products, regions, seasons, channels, or customer groups instead of one uniform price.
Reasons for Structured Pricing
- Market Segmentation: Different customers have different willingness to pay (e.g., students, premium buyers, rural/urban consumers).
- Product Line Pricing: Different versions of a product require
MapReduce Fundamentals: Architecture, Matrix Multiplication, and Distributed Processing
MapReduce Algorithm for Matrix Multiplication
- Input matrices A and B are stored in HDFS.
- Map Phase: Emits key-value pairs for each element multiplication.
- The Mapper emits the key
(i, j), where the value isA[i][k] × B[k][j]. - Shuffle Phase: Groups all intermediate values by the key
(i, j). - Reduce Phase: Sums all values associated with each key
(i, j). - The final result
C[i][j]is the summation:Σ A[i][k] × B[k][j]. - Each Mapper processes a partial multiplication set.
- The Reducer aggregates these partial
Mathematical Functions: Definitions, Types, and Properties
Mathematical Functions: Core Concepts
Function: A rule or correspondence that associates each element $x$ of one set with one and only one element of a set $y$. It is a special relationship between elements of two sets.
Elements of a Function
- Domain: For a function $f: A \to B$, the domain corresponds to the first set ($A$).
- Codomain: The second set ($B$), which contains all possible values related to the elements of the domain.
- Image of a Function: The set of all output values obtained by applying the
How do we know the homo sapiens did interbreed with homo neandrethalensis, homo erectus, and homo floriensis before their species all died out?
that philosophy is a way to reflect on certain questions of interest to human beings like that is the reality? That we know? To humans.
branches of philosophy raises questions about the metaphysical nature of existence and about how that success has come to exist on ten questions about reality.
Epistemology is the branch of philosophy that studies the problems related to knowledge and that is the conditions that make possible the criteria of truth and certainty , anthropology studies human beings

·A “Bourdon Tube” is used in: PRESSURE SENSORS
1)CCD Camera?
A CCD (Charge Coupled Device) is an electronic sensor used in cameras to capture digital images
It converts light → electrical charge → digital data
Each pixel stores charge proportional to the light intensity, forming the image
Construction
CCD is based on a MOS (Metal–Oxide–Semiconductor) structure, not a simple pn junction
Main parts:
P-type semiconductor body
Thin silicon dioxide insulating layer
Array of gate electrodes
When a positive voltage is applied to the gate:
Holes are repelled

Parallel and Distributed Programming Models
Parallel Programming Models
Shared Memory Model: Allows all processors to use the same memory space.
Distributed Memory Model: Uses separate memory for each processor and relies on message passing.
Data Parallelism: Applies the same operation to many data items at once.
Task Parallelism: Runs different tasks in parallel on possibly different data.
Distributed Programming Models
- Client-Server Model: Involves clients requesting services and servers providing them.
Athenian Social Structure: Citizens, Metics, and Slaves
Unit 5: Social Groups: Free and Unfree
Social Classes in Athens
There were three main groups in Athenian society:
- Citizens
- Metics
- Slaves
Citizens
Citizens were born in Athens (Athenians). They possessed all political rights and obligations—political, economic, and social. The most important decisions concerned this group. The worst consequences they could face were being deprived of their civil rights or being exiled from Athens. Citizens were dedicated to managing and administering the city.
Metics

Muscular Tissue: Structure and Components
Muscles are made up of highly specialized, thin, and elongated cells called muscle fibers. The muscle fibers contain specialized cytoplasm called sarcoplasm that contains a network of membranes called the sarcoplasmic reticulum. The muscle fibers may be bounded by the cell membrane called the sarcolemma. Each muscle fiber may contain numerous longitudinal fibrils called myofibrils.
Basic Physiological Properties of Muscle Tissue
- Contractility
- Excitability
- Extensibility
- Elasticity

Romanticism
- Sources: Late seventeenth-century Germany.
- Opposition to: The neoclassical concept.
- Romantic Human: Dissatisfaction with reality, a search for an alternate time-space, sadness. A very romantic end often involved suicide.
- Creative Act: Emphasized imagination and originality; the concept of the artist as a *genius*.
- Attraction to: The dark, mystery, chaos—everything opposed to reason.
- Customs: A step from the romantic toward realistic acting
