Notes, summaries, assignments, exams, and problems for University

1.      18 Is it a requirement for the ARPA to provide warning on connected external equipment?

Yes

2.      Is it a requirement for an ARPA to be sea and ground stabilised?

Yes

3.      Comparing manual and automatic acquisition, which is most sensitive?

Manual acquisition

4.      What is the difference between a tracking gate and a tracking window?

It is the same thing

5.      What is the purpose of digitizing the radar echoes?

The ARPA tracking system only work with digital signals

6.      What is the purpose of the steady course filter?

Provide stabile target information

7.      Can a target reduction of speed activate the fast filter?

Yes

8.      Can a target course change deactivate the slow filter?

Yes

9.     

4.1 The stages of learning as Dienes
The learning process is a process based on abstraction, generalization and communication. This process of abstraction is to accurately analyze and Dienes identifies six different stages in it:
Stage 1: introduces the individual in the middle => Game Free
2nd stage: review, manipulate, get rules => Structured Games
3rd stage: becoming aware of the common structure to games made
4th stage: representation of the common structure graphically or schematically => Stage representative
5th stage study of the properties of abstract structure, which implies the need to invent a language => Stage symbolic
6th stage: Construction of axioms and theorems => formal Stage
Her pedagogical approach

36.      Does current and drift effect the True vector on a relative motion display?

Yes

2.      If you input gyro course to the ARPA, what can you expect?

Error in other ships calculated course

3.      Why is raster scan display “lock up” so dangerous?

The displayed information is no longer relevant

4.      What is dangerous with operating the ARPA in mixed mode over time?

Forgetting that this actually in mixed mode

5.      What can you expect from the ARPA target tracking system in auto acquisition mode?

Small and weak targets may not be acquired

6.      Doesthe line connecting the PAD or POS whit the target indicate target speed?

No

7.      What is the meaning of a flashing triangle, apex pointing down?

New target

Packet Switching Fundamentals

Packet switching is a method used in computer networks to transmit data efficiently by breaking it into smaller units called packets. Each packet travels independently across the network and may take different routes to reach the destination. Once all packets arrive, they’re reassembled into the original message.

How Packet Switching Works

1. Segmentation: The original message is divided into packets.
2. Header Information: Each packet receives a header with source, destination, and sequencing information.
3. Independent Routing: Packets are sent through the network, possibly via different paths.
4. Reassembly: At the destination, packets are reordered and combined to form the original message.

Advantages of Packet Switching

• Efficient

Ideological Foundations of Government's Economic Role

Public finance economists examine both the actual effects of government taxation and spending, as well as what these activities should be. Views on government's economic role are shaped by ideological perspectives on the relationship between individuals and the state.

Individualistic vs. Collectivist Approaches

Two main approaches influence public policy and economic decisions:

1. Individualistic Approach: Prioritizes individual freedom and limits government intervention.
2. Collectivist Approach: Emphasizes collective well-being and a more significant government role.

The Organic View of Government

This perspective considers society as a living organism, where each individual is a part that contributes... Continue reading "Government's Economic Role: Ideologies & the Organic View" »

Technological Progress and Innovation

Technological progress was the very heartbeat of the Industrial Revolution. It was not a single invention that changed everything, but rather a continuous process of innovation. Macro-inventions, such as the steam engine or mechanical spinning machines, opened entirely new possibilities. These groundbreaking innovations were then followed by micro-inventions—smaller, cumulative improvements that refined and expanded their use.

In the textile industry, a series of pivotal inventions revolutionized the production of cotton, making Britain the dominant textile exporter by the 19th century. Key advancements included:

• The flying shuttle (John Kay, 1733)
• The spinning jenny (James Hargreaves, 1764)
• The water frame

The Human Respiratory System

By Marco Rios

Ventilation: Air Movement in the Lungs

Pulmonary Ventilation

The total volume of air breathed in and out per minute.

Alveolar Ventilation

The volume of air exchanged between the atmosphere and the alveoli per minute.

The Lungs: Core Organs of Respiration

A pair of organs consisting of the lower part of the respiratory airways, pulmonary circulation, and connective tissue.

Pleural Sacs and Cavity

Thin, fluid-filled membranes that enclose the lungs. The space between the pair is known as the pleural cavity.

Alveolar Cell Types

Type I Cells

Form the walls of the alveoli, facilitating gas exchange.

Type II Cells

Secrete pulmonary surfactant.

Pulmonary Surfactant

A substance that reduces the surface tension of water inside... Continue reading "Human Respiratory System Functions" »
