Bluetooth is a short-range wireless technology standard for exchanging data over short distances using radio transmissions in the 2.4 GHz band. It allows for ad-hoc connections between devices within 10 meters using frequency hopping spread spectrum and time-division duplexing. Bluetooth devices can connect in a piconet topology managed by a master device or scatternet topology connecting multiple piconets. The Bluetooth protocol stack includes layers for radio, baseband, link management, logical link control and adaptation, and various service protocols.

A Novel Solution To The Short Range Bluetooth Communication pijans
Bluetooth is developed for short range communication. Bluetooth Devices are normally having low power
and low cost. This is a wireless communication technology designed to connect phones, laptops and PDAs.
The greater availability of portable devices with Bluetooth connectivity imposes wireless connection
between enabled devices. On an average the range of Bluetooth devices is about 10 meters.The basic
limitation of the Bluetooth communication is this range limitation. In this paper I have studied the
limitations of Bluetooth communication and consider range constraint as the major limitation. I propose a
new expanded Blue tooth network to overcome the range constraint of Bluetooth device. This creates a
network of Bluetooth enabled devices that will include laptops, set top devices and also mobile phones. The
main purpose of this proposal is to establish a network will enable the users to communicate outside the
range without any range constraint.
This presentation is an introduction to bluetooth technology. Seminar created for the Internet of Things course, with Prof. F. Palmieri at the University of Salerno (UniSa).
Bluetooth is an open standard for wireless communication. It uses for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves.
The name derives from the Viking king Harald Blatand Gormsson, born around 900, he became famous for having unified the Scandinavian lands, which under his kingdom corresponded almost to today's Denmark, Norway and Sweden.

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.
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.
