18th and 19th Century Socioeconomic Transformations in Europe
Demographic Revolution
In the 18th century, population growth was low due to high mortality rates, poor nutrition, inadequate hygiene, and a lack of vaccinations. In addition, wars and plagues contributed to the low population growth. There was also a high birth rate due to a lack of contraception and religious and cultural factors. However, in the 19th century, European mortality rates decreased in many places due to the development of medicine (vaccines), improved hygiene (soap), and better nutrition

**Glossary of Marxist Philosophy**
**Alignment**
Also known as *alienation* or *estrangement*. It refers to the circumstance in which a person is not the master of themselves, or ultimately responsible for their actions and thoughts. For Marx, it is the condition in which the oppressed class lives in every exploitative society, in any society that supports private ownership of the means of production.

Spanish Agrarian Structure: Transformations & Rural Population
Agrarian Structure in Spain
Agrarian Structure – Past and Present:
- Traditional Structure: Characterized by labor-intensive farms, extensive and backward technology, low yields, and production for local consumption protected by internal market tariffs.
- Current Structure: Characterized by a small and aging population, increasing farm sizes, greater intensification, and technological advancements. This has led to higher yields, regional specialization, and sales in a globalized market.

Rationalism and Empiricism
Rationalism and empiricism are epistemological positions that seek to understand how we know the world. Empiricism emphasizes the role of the senses, asserting that knowledge originates from sensory experience. Empiricists argue that nothing exists in the mind that was not first in the senses. All that comes to mind comes from the senses, through a process that begins with sensory input. For empiricists, there are no innate ideas, and truth is not universal because it depends

Telecom Signal Processing: PCM, Quantization, Multiplexing
Digitalization of Telephone Channels and Quantization Distortion
The telephone channel, a unidirectional path with a bandwidth of 3100 Hz (300 Hz to 3400 Hz), can be digitalized using Pulse Code Modulation (PCM). When combined with Time Division Multiplexing (TDM), it enhances the efficiency of transmission paths. PCM converts analog samples into digital forms, improving noise immunity during transmission. The analog signal undergoes three operations in an Analog-to-Digital (A/D) converter before

Scientific Method and Knowledge
Scientific method: Modern science relies on knowledge obtained through objective observation, experimentation, and logical reasoning. This knowledge must be verified or rejected by observation. The goal is to use verified results to construct theories that explain why phenomena behave the way they do.
Components of the Scientific Method
- Empirical verification
- Falsifiability
- Non-normative research
- Transmissible
- Cumulative
- Empirical generalization
- Explanatory
- Predictive
- Probabilistic
