Network Fundamentals: Protocols, Streaming, and Reliable Data Transfer

Core Networking Concepts

Circuit Switching Fundamentals

In circuit switching, first maximize the smallest link, then proceed to maximize the subsequent links.

Total Network Delay Components

Total delay is calculated as the sum of:

  • Processing/Nodal Delay
  • Queue Delay
  • Transmission Delay (Trans)
  • Propagation Delay (Prop)

Bandwidth-Delay Product (BDP)

The Bandwidth-Delay Product (BDP) represents how much data fits within the “pipe” (where delay is the length and bandwidth is the width). To find the number of pipes,

EU Internal Market Freedoms: Capital, Services, and Goods Regulation

1. Historical Development of Free Movement of Capital

Free movement of capital developed later and more cautiously than the other economic freedoms because the original Treaty rules were vague and ambiguous. Unlike goods, workers, establishment, and services, capital was not granted immediate liberalization or direct effect. During the 1960s and 1970s, the Court of Justice recognized direct effect for the other freedoms, but capital movements were excluded. Liberalization was meant to happen progressively

Everyday Lies: How Deception Erodes Trust and Integrity

Lying as a Daily Habit

Lying as a Daily Habit: A Critical Analysis of The Ways We Lie. Lying is such a common practice that it often becomes normalized in everyday life. In her essay The Ways We Lie (1992), Stephanie Ericsson argues that lying is not an isolated act but rather a spectrum of strategies we use to protect ourselves, manipulate others, or avoid conflict. Although many lies are justified as necessary or harmless, every lie carries a cost: it erodes trust, distorts communication, and weakens

Materials and Stores Management: Inventory Control & Logistics

Materials Management

1. Meaning of Materials Management

Materials management is the process of planning, purchasing, storing, and controlling materials in an organization to ensure their availability at the right time, in the right quantity, quality, and at the lowest cost. It covers the entire flow of materials from suppliers to the production department and finally to distribution. The main purpose of materials management is to maintain a smooth and uninterrupted production process while avoiding

Inventory & Logistics Glossary: Essential Supply Chain Terms

A

ABC Analysis

Assigns items to groups (A, B, C) based on value and importance.
Example: A = laptops, B = keyboards, C = mouse pads.

Accumulation

Receiving goods from multiple sources.
Example: A DC receives shipments from 10 factories.

Activity-Based Costing (ABC)

Assigns cost based on activities, not departments.
Example: Shipping-heavy customers show higher cost-to-serve.

Allocation

Matching inventory to customer orders.
Example: DC allocates 50 units to a customer order.

Marxist Theory: Value, Surplus, and Capital Accumulation

Chapter 2: The Qualitative-Value Problem

1. Commodity – The Starting Point

A commodity = anything made to sell, not for personal use.

Marx studies exchange as a social process, not just a trade of things.

2. Two Sides of a Commodity

  • Use Value → Usefulness (satisfies wants).
  • Exchange Value → How much it trades for.

Marx focuses on exchange value because it shows social relations in capitalism.

3. Value Comes from Labor

The value of a commodity comes from labor used to produce it.

Labor has two sides:

They proposed new forms of social organisation and government. All of this led to the revolutionary cycle that began in France in 1789.

The social and economic crisis

  • The economic crisis was the result of a series of poor harvests

Two-Way Slab Design Calculations: Steps and Formulas

Step 1: Design Constants

  • For M20 & Fe415:

    • τc max = 1.4 N/mm² (from IS:456 Table 73)

    • σ = 2.76 (used in moment capacity formula)


Step 2: Effective Span Calculation

Slab Type Check

  • Cy/Cx = 6/4 = 1.5, which is < 2 → Two-Way Slab Panel

Effective Depth Calculation

Using IS 456 empirical formula:

$$\frac{L}{d} = \text{MF} \times \text{BF}$$

  • Basic factor (BF) = 26

  • Modification factor (MF) = 1.3

$$d = \frac{L}{\text{MF} \times \text{BF}} = \frac{6000}{1.3 \times 26} = 177.51 \, \text{mm} \approx 180 \, \
