Process Scheduling & Memory Management: SRT, HRN, Queues, RAM
SRT (Shortest Remaining Time)
The next process to enter the processor is the one with the shortest remaining runtime. When a new process arrives with a shorter runtime than the currently running process, the latter is evicted from the CPU, and the shorter process begins execution. It’s a preemptive variant of the Shortest Job Next (SJN) algorithm.
Features:
- Variation of SJN.
- Preemptive policy.
- Very efficient.
- Possibility to assign priorities, where the system adjusts runtime based on priority (multiplying
Steam Power and Internal Combustion Engines: Principles and Operation
Cycle of Steam
The majority of installations for power generation from burning fuel (thermal) are steam-based, and these plants work according to variations of the Rankine thermodynamic cycle.
Plants usually utilize water steam as the working fluid and operate by burning solid, liquid, or gaseous fuel. Its main components are illustrated in Figure 3.1, where one can identify:
- Steam turbine
- Condenser
- Feed pump
- Boiler (steam generator)
- Chimney
- Electric Generator
- Cooling System (cooling tower)
As seen in Figure

Q cannot deduct any other. A set of rules or transformation (q interference) allows us to move from one well-formed formula (wff) to another wff.
Deductive-Perfect Systematization: Ideal logical rigor, no tacit assumptions, inability to obtain a contradiction in the system, a lesser number of axioms. Consistency requirements (not leading to internal contradictions), completeness (sufficient means to derive all valid statements q can form in their language), decidability (possibility to determine

Constitutional Supremacy
Constitutional supremacy is a fundamental principle where policy is legally bound by the supreme authority of constitutional norms.
Rigidity of the Constitution
A rigid constitution, such as outlined in Article 132, has specific procedures for amendments, distinct from ordinary legislation.
Constitutional Gaps (Ferrajoli)
- Primary Gaps: Absence of a standard requiring specific behavior.
- Secondary Gaps: Lack of mechanisms to invalidate violations or impose sanctions.

ITEM 29. THE JUDICIARY AND THE PUBLIC PROSECUTOR
I. The Constitutional Setting of the Judiciary
The constitutional state is based on the separation of powers, or more precisely, on the material division of functions and the formal separation of powers. This means that state activity is recognized in distinct functions—ordinary tasks of very different material nature that are traceable to three core functions: the function to pass laws (legislation), the function of executing the mandates of these

David Brandon Garza Montalvo 2641267
Karl Marx lived in the early nineteenth century, a time when much of the world, especially Europe and the United States, was experiencing the Industrial Revolution that began in England. Marx analyzed the capitalist system, arguing that it was based on ideology, the way people think within that system. Capitalist ideologues viewed ideas as the starting point for understanding society, while Marx believed that material conditions determined how a society functioned.

First Sociology of Crime: Merton and the Chicago School
Merton’s Anomie Theory
Merton discarded the idea that solely regulatory control (or lack thereof) produces anomie. He viewed deviation as a normal adaptation to a competitive environment, not just a biological escape from lacking social control. Merton identified two key elements in a society’s cultural structure:
- Culturally defined goals
- Institutionalized means to achieve them
In a well-regulated society, goals and means are integrated. Poor integration

Cuban War of Independence and Spanish-American War: Origins, Conflicts, and Consequences
The War in Cuba: Genesis of the 1895 Insurrection
After more than 15 years of colonial life under a truce, preparations for the uprising were underway in Baire, commencing on February 24, 1895. Conspiracies against Spain had been ongoing, with some groups seeking new insurrection. Two prominent factions emerged: the pro-autonomy Constitutional Union, advocating for negotiations, reforms, and legal equality with Spain, and the Cuban Revolutionary Party (CRP), demanding complete independence.
On February

Rocks: Formation, Types, and Characteristics
A rock is a naturally occurring mineral aggregate with cohesive properties. Rocks are categorized into three main types based on their formation:
Igneous Rocks
Igneous rocks (from Latin ignis = fire) form when molten rock (magma) cools and solidifies.
Magma Characteristics
