Fundamentals of Engineering Research: Definition and Process

Meaning of Research

Research refers to a careful, well-defined (or redefined), objective, and systematic method of search for knowledge, or formulation of a theory that is driven by inquisitiveness for that which is unknown and useful on a particular aspect so as to make an original contribution to expand the existing knowledge base.

  • Research involves formulation of a hypothesis or proposition of solutions, data analysis, and deductions; and ascertaining whether the conclusions fit the hypothesis.

Blockchain Fundamentals: Definition, Architecture, and Operation

1. Defining Blockchain and Architecture

What is Blockchain?

Blockchain is a distributed and shared ledger where data is stored in blocks. Each block is linked to the previous one, and data can be updated only with the agreement of all nodes. Once stored, data is very difficult to change, and no central authority is required.

Architecture of Blockchain

  1. Internet Layer: Provides basic communication between nodes.
  2. Peer-to-Peer Network: All nodes connect directly without a central server.
  3. Transactions: Records

Understanding Cyberspace Architecture and Cybercrime Threats

Cyberspace refers to the virtual environment created by computers, the internet, digital networks, and communication technologies. It is not a physical space but a digital world where users interact through devices such as computers, smartphones, servers, routers, and cloud systems. Activities like browsing websites, sending emails, online banking, social media communication, and digital payments all take place in cyberspace. It connects millions of people globally and enables fast information sharing,

Probability Density Functions and Distributions

A function f(x) is a valid probability density function (PDF) if:

  • f(x) ≥ 0 for all values of x.
  • -∞ f(x)dx = 1.

Expectation and Variance

  • Expected value (mean): E[X] = ∫-∞ x ⋅ f(x)dx
  • Expected value of X2: E[X2] = ∫-∞ x2 ⋅ f(x)dx
  • Variance: Var(X) = E[X2] – (E[X])2

Special Probability Models

  • Uniform Distribution: f(x) = 1/(b-a), for a ≤ x ≤ b.
  • Uniform Distribution Expected Value: (a + b)/2
  • Exponential Distribution: f(x) = λe-λx,

Fundamentals of Energy Systems: Definitions and Structure

1. System Definition and Differentiation

What is a system? A system is a set of distinguished and active elements (objects, operations, processes) with existing relations between those elements. It is separated from its surroundings, yet it is under the impact of the surroundings and has an impact on the surroundings. It is organized and intentionally arranged for the realization of a defined purpose within its surrounding environment.

System vs. Set: A system implies active elements, defined relations,
