ADSL (Asymmetric Digital Subscriber Line) enables faster data transmission over copper telephone lines than conventional modems. It uses frequencies not used for voice calls, allowing voice and data simultaneously. ADSL can transmit up to 4-5 km from the central office but sometimes farther depending on wire quality. At the exchange, a splitter separates the voice and data signals with data routed over the telephone data network and eventually the Internet.
A presentation on the physical layer basics of ADSL. I presented this to a couple of colleges in the southeast as a guest lecturer, and to the local chapter of the IEEE Signal Processing Society.

A WAN (Wide Area Network) is a network that covers a broad area (i.e., any telecommunications
network that links across metropolitan, regional, national or international boundaries) using leased
telecommunication lines. Business and government entities utilize WANs to relay data among
employees, clients, buyers, and suppliers from various geographical locations. In essence, this mode of
telecommunication allows a business to effectively carry out its daily function regardless of location. The
Internet can be considered a WAN as well, and is used by businesses, governments, organizations, and
individuals for almost any purpose imaginable.

This is the Webinar DTC and Meru Networks hosted on 8/25.
Discussed is 802.11n technology and How Meru Networks addresses of the problems seen in the market with other Wireless Network providers.
Digital Subscriber Line is a data communications technology that transmits data faster over the simple copper telephone lines. The signal encoding of xDSL technology is illustrated by a set of modulation techniques. This journal will overview the xDSL technology and will discuss subjects on the efficiency of these modulation techniques.

Broad band theologies are now available all over the word. Because of the technological development is giving more opportunities to improve communication development such as xDSL technologies. Implementation of Digital Subscriber Line technology originally was part of the Integrated Services Digital Network (ISDN) specification and it was published by published in 1984 CCITT and ITU.xDSL represents individual varieties of DSL technology such as ADSL,VDSL,RADSL…. etc.
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.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

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.
