Fostering Health for Academic Success

The link between good health and academic success is strong. Studies consistently show that issues like obesity and physical inactivity can affect students’ ability to pay attention in class.

First of all, we must help children become healthier in places where they spend much of their time, such as school. We suggest that schools should not only replace high-sugar and high-fat meals with healthier food but also remove unhealthy snacks.

In addition, it would be a great idea to start using programs that:

• Teach kids about personal safety.
• Protect against illness.
• Warn about the dangers of drugs, alcohol, and tobacco.

To sum up, a positive school climate always brings the joy and fun back into teaching and learning.... Continue reading "Enhancing the School Experience for Student Success" »

Understanding Key Digital Marketing Concepts

Search Engine Marketing (SEM)

Search Engine Marketing (SEM) is a process that utilizes multiple methods to improve market visibility and exposure for a brand, product, or service.

Search Engine Advertising (SEA)

Search Engine Advertising (SEA) allows you to directly display your paid advertisements among the search results on various search engines, such as Google, Bing, and Yahoo.

Content Marketing

Content Marketing is a type of marketing that involves the creation and sharing of online material (such as videos, blogs, and social media posts) that does not explicitly promote a brand, but is intended to stimulate interest in its products or services.

Press Release

A Press Release is a written or recorded... Continue reading "Essential Digital Marketing Terms Explained" »

International Air Transport Association (IATA)

IATA is the International Air Transport Association, a trade association for the world’s airlines. It promotes cooperation, safety, reliability, confidence, and economy in air transport, benefiting its private shareholders.

• IATA represents 290 airlines, accounting for 82% of worldwide air traffic.
• It was established in 1945 in Havana, Cuba.
• IATA seeks common solutions for industry problems that individual airlines cannot solve alone.

IATA Airport and Airline Codes

• IATA Airport Codes: These are 3-letter codes used to designate airports worldwide.
• Cities with multiple airports also have a specific code to designate the city itself (e.g., NYC for New York City).
• Airline Designators:
  • IATA codes (2 letters)

Automatic Voltage Control

Basically consists of a main exciter field which excites the alternator field to control the output voltage. The exciter field is automatically controlled through an error equal to V reference - Vt. When the output voltage is higher than the required value, the BT is measured by a potential transformer and fed back to the input so that the error V reference - Vt is applied to the exciting field. This ensures that the generator output voltage is maintained at the desired level.

Components:

• Potential Transformer: Provides a sample of terminal voltage
• Differentiating Device: Gives actuating error e = V ref - Vt
• Error Amplifier: Amplifies the error signal
• SCR Power Amp: Transfer Function = (ke / 1 + TeS)
