We present a new method to protect projected content from secret photography using high-speed projection. In this study, we aim to realize a protectable projection method that allows people to observe content with their eyes but not record content with camera devices. To achieve this goal, we exploit the difference between the human vision system and the camera vision system. Notably, humans cannot recognize the high-speed changes of light. We were inspired by previous work that used these properties to show on-screen invisible markers. There are several studies that aim to present imperceptible on-screen markers using high-speed projection between the afterimage effect of human eyes and shutter speeds of digital cameras. From another point of view, these techniques show specific content only to the human eye while showing different content to a camera. Thus, we can project images that can be seen by human eyes whereas cameras only capture an incomplete frame. Therefore, this means the projected light is unphotogenic.

Jamel Gantt is New York City based photographer and artist, specializing in architectural and interiors. He has photographed many projects in his professional career. He is talented and possess a good eye for composing great photographs. e has the ability to photograph interior and exterior shots which are artistic, eloquent and beautiful. He brings a unique and creative perspective to the places he visits. He knows which angle gives a room the life force and tells that story to the viewer.
Design and Development of Secure Navigation System for Visually Impaired Peopleijcsit
Ā
The proposed work presents a navigation system, which detects the obstacles and also guide to visually impaired people about appropriate path. The system we propose detects the obstacle via an infrared based detecting system and sends back vibro-tactile or sound (buzzer) feedback to inform the user about its position. The most common method of obstacle detection, used by blind people is the walking stick. The limitation of walking stick is that, it does not provide protection near to head area. A sensor module is fixed on a light weight cap allowing the user to obtain the information about obstacles (near to head area) and also about correct path on which the user should move. When the user uses this system with cane, he is fully protected about obstacles and can navigate freely into the environment.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
Ā
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 Caesarās dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empireās 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 Empireās 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.
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.

Operation āBlue Starā 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.

3. Aperture crack, gap, etc. An opening, usually circular, that limits the quantity of
light that can enter an optical instrument.
1. Aperture
Shutter is opened to enter light and thus expose the film (or the electronic
image sensor ISO). Adjustable shutters control exposure time, or the length of
time during which light is entered.
2. Shutter
3. ISO
Sensor
ISO is your camera's sensitivity to light.
There are 3 ways to control how much light camera takes in:
1.Aperture.
2.Shutter Speed.
3. ISO (Sensor)
4. Controlling
of light
5. Camera
angle
The camera angle marks the specific location at which the camera is placed
to take a shot. ... The different camera angles will have different effects on
the viewer.
Medium Shot. Close-up. The Long Shot. Low Angle. High Angle.
Extreme Close-up. Over The Shoulder
