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

Society in the 21st century is increasingly multilingual. Recognizing this, the Ikastolas in the Basque Country felt the need to review and expand their linguistic objectives in 1990. This led to the creation of the "Eleanitz" multilingual project, a significant initiative in early language education.

The Eleanitz Multilingual Project: Key Characteristics

The Eleanitz project was designed with several core characteristics:

• It is an integrative model catering to learners from diverse cultural and linguistic backgrounds.
• Spanish, while the L1 (first language) for many students, was considered the L2 (second language) of the school and was introduced as a separate subject at the age of eight.
• L3 (English) was introduced at the early age of four. This

Present Simple

Describes habitual actions, facts, and general truths.

Formulas:

• (+) Affirmative: Subject + Base Verb (+s/es for he/she/it) + Complement
  • Example: I play tennis. She cooks dinner.
• (-) Negative: Subject + do/does + not + Base Verb + Complement
  • Example: I don't play tennis. She doesn't cook dinner.
  • Note: The 's' is not added to the verb when 'does' is used.
• (?) Interrogative: Do/Does + Subject + Base Verb + Complement?
  • Example: Do I play tennis? Does she cook dinner?

Present Continuous

Describes actions happening now or around the present moment.

Formulas:

• (+) Affirmative: Subject + Verb to be (is/are/am) + Gerund (-ing) + Complement
  • Example: We are writing in English class.
• (-) Negative: Subject + Verb to be (is/are/am) + not + Gerund (-ing)

Problem 1: Calculating Clock Rate

When a program is run on Computer X, 50% of the execution time is CPU time. A better Computer Y reduces the execution time by 20%. It is known that Computer Y has a clock rate of 2 GHz, and it takes Computer Y 10% more clock cycles to execute the program. In addition, Computer Y can only reduce CPU time. What is the clock rate in GHz of Computer X? The answer must have exactly one digit after the decimal point, even if it is zero, e.g. 2.0 or 0.9.

[Clock Rate Y - (Clock Rate Y)(Clock Cycle % Y)] - [Clock Rate Y - (Clock Rate Y)(Clock Cycle % Y)][Computer Y Reduction Time]

2 GHz - (2 GHz)(10%) = 1.8 GHz

1.8 GHz - 1.8 GHz(20%) = 1.44 GHz

Answer: 1.4 GHz

Linguistic Definitions: Phonology, Morphology, Syntax, Semantics, and Pragmatics

Phonology: The study of the sound system of a particular language.

Morphology: The study of the form and formation of words in a particular language, including the arrangement of sounds into minimal meaningful units (morphemes) and the classification of words into parts of speech.

Syntax: The study of how words are arranged into higher units, such as phrases, clauses, and sentences, focusing on word order.

Semantics: The study of meaning.

Pragmatics: The study of language in use, including the function of language in its social context, covering a wide range of topics.

Implicature and Grammaticalization

Implicature: What the speaker means or implies rather than what he... Continue reading "Understanding Linguistics: Phonology, Morphology, Syntax & Semantics" »

Learner Needs

Learner Needs: When a learner learns a foreign language, he or she has various kinds of needs which influence his/her learning.

• Personal needs: need for praise, need to become more fluent.

• Professional needs: learning English to give presentations.

Approaches to Language Teaching

Approach: Our view of a language or view of how learning a language takes place.

• They involve our beliefs about teaching, language learning, and how we translate all of these into classroom practices.

Presentation, Practice and Production (PPP)

A common teaching sequence:

1. Presentation: of an aspect of language in a context that students are familiar with.

2. Practice: students do an activity to become familiar with it.

3. Production: students will use the language in

Mastering English Modals: Should and Ought To

Understanding "Should" for Advice

The modal verb "should" is used to give subjective advice and opinions. We often use "should" with phrases like "I think" or other expressions that indicate personal belief. It suggests a recommendation that the listener can choose to follow or not.

(Se utiliza para dar consejos u opiniones; la decisión de seguirlos es tuya.)

Examples of "Should"

• In my opinion, you should back up your files.
• I think you should save this information on your pendrive.

Structure for "Should"

Affirmative/Negative: Subject + should/shouldn't + base verb + complement

WH Questions: (Wh-word) + should + subject + base verb + complement?

"Should" Question Examples

• Should I share my photo?
• Why should

An electronic circuit is a combination of components that function as a whole to perform a certain treatment of electrical signals. Examples include generating radio waves, significantly increasing the power of the signal, and recovering images.
The active components are those that can generate, modify, or expand the electrical signal, such as batteries, generators, diodes, and transistors.
The passive components are those that provide no gain but consume electricity, such as capacitors, resistors, and inductors.

Integrated circuits are electronic circuits in which components are microscopic in size and are contained within a silicon crystal, called a chip. Each chip is enclosed in a plastic sleeve, and the sides have a set of pads that connect... Continue reading "Understanding Electronic Circuits and Their Components" »

Hydraulic Systems: Principles and Applications

I. Fundamentals of Hydraulics

1. What is a hydraulic system?

A hydraulic system consists of hydraulic fluid, pistons or rams, cylinders, an accumulator or oil reservoir, a complete working mechanism, and safety devices.

2. What are hydraulic systems used for?

These systems are capable of remotely controlling a wide variety of equipment by transmitting force, carried by the hydraulic fluid, in a confined medium.

3. How is force transferred in hydraulic systems?

These systems transfer high forces rapidly and accurately, even through small, lightweight pipes of any shape, and over long distances.

4. Name at least 6 areas in which hydraulic systems are applied.

1. Automobile garages
2. Petrol pumps (Gas stations)
3. Measuring

Understanding Key Writing Approaches in Language Learning

The Controlled-to-Free Approach

This approach promotes precision, focusing primarily on grammar, syntax, and overall text structure. Students initially work at the sentence level and then progress to the paragraph level, which they manipulate with a specific goal. In this type of exercise, students are often asked to change singulars to plurals, alter temporal sequences, or combine sentences in various ways. This method enables students to write texts of reasonable length while minimizing errors.

The Free-Writing Approach

In this approach, more emphasis is placed on quantity than quality. Students are encouraged to write about any topic they are interested in without worrying excessively... Continue reading "Pedagogical Writing Strategies for Language Acquisition" »
