Luth Oliveira introduces the basic audio properties of propagation, amplitude, frequency, and timbre. Propagation refers to how sound travels through a medium like air or water. Amplitude represents the maximum displacement of a sound wave and is measured in decibels, with higher amplitudes relating to louder volumes. Frequency is the number of cycles per unit of time and is measured in Hertz. Timbre distinguishes different musical instrument sounds and refers to the unique tone color of each.
Sound waves are produced by the vibration of material objects. A disturbance in the form of a longitudinal wave travels away from the vibrating source. High-pitched sounds are produced by sources vibrating at high frequency, while low-pitched sounds are produced by low-frequency sources Sound waves consist of traveling pulses of high-pressure zones, or compression, alternating with pulses of low-pressures zones, or rarefaction. Sound can travel through gases, liquids, and solid, but not through a vacuum.

Main constraint for colour TV was compatibility with existing monochrome system. It should produce normal black and white picture on monochrome receiver without any modification on receiver circuitry. Moreover colour receiver must produce a black and white picture if transmission is monochrome.
Hence it should have same - bandwidth, location & spacing of sound and video frequencies, luminance information as a monochromatic signal. Colour information in signal should not effect picture on a monochrome receiver. Other circuit details of colour receiver should be same as that of monochromatic receiver..

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Introduction
Hi, I'm Luth Oliveira from Salvador, Bahia,
Brazil, and this lesson is for week 1 of
Introduction To Music Production at
Coursera.org. I will be teaching the audio
basics: Propagation, Amplitude, Frequency,
and Timbre.
3. Basic properties of Sound
As important as start producing, learning some
basic properties of sound let us aware of what
we are really matipulating. These properties are
known as: Propagation, Amplitude, Frequency
and Timbre.
4. Propagation
It is the act or process of propagating, especially the process by
which a disturbance, such as the motion of electromagnetic or
sound waves, is transmitted through a medium such as air or water.
(American Heritage Dictionary)
Besides the medium, other factors can affect the speed of sound,
for instance, the temperature. But in our condition, we will conceed
the speed of sound around 340 m/s through the air in standard
conditions of temeperature and pression: 20ºC/68ºF and 1atm(sea-
level).
5. Amplitude
The absolute value of the maximum displacement
from a zero value during one period of oscillation.
(Dictionary.com). In other words, it is the extension of
the wave, measured in decibels (Db).
The volume of sound is proportional to the amplitude of
the wave. The higher is the amplitude, the higher is the
volume and vice versa.
6. Amplitude x Loudness
Although the relation between the two terms,
they are differen in their applications.
Amplitude is something measurable by a
computer, and loudness is our perception of
that.
7. Frequency
It is the number of cycles per unit of time and
is measured in Hertz (Hz).
8. Frequency x Pitch
Like Amplitude, Frequency is related to
another term but can not be interchanged.
Frequency is what the computer measure and
pitch is something that we percieve.
9. Timbre
Also known as tone color or tone quality, timbre is the
quality of a musical note, sound, or tone that
distinguishes different types of sound production, for
instance the sounds of musical instruments. The
example below shows the different wave forms for the
same note playied: A, 440Hz.
