Early life and education Bose was born in Philadelphia, Pennsylvania, to a Bengali father, Noni Gopal Bose and an American mother, Charlotte Mechlin (1895-1973). His mother was a schoolteacher of French and German ancestry. His father was an Indian independence activist who, having been imprisoned for his political activities, fled Bengal in the 1920s in order to avoid further persecution by the British colonial police. Bose first displayed his entrepreneurial skills and his interest in electronics at age thirteen when, during the World War II years, h ...

Indian Independence Movement
The Indian independence movement was a series of historic events in South Asia with the ultimate aim of ending British Raj, British colonial rule. It lasted until 1947, when the Indian Independence Act 1947 was passed. The first nationalistic movement took root in the newly formed Indian National Congress with prominent moderate leaders seeking the right to appear for Indian Civil Service examinations in British India, as well as more economic rights for natives. The first half of the 20th century saw a more radical approach towards self-rule. The stages of the independence struggle in the 1920s were characterised by the leadership of Mahatma Gandhi and Congress's adoption of Gandhi's policy of non-violence and Salt March, civil disobedience. Some of the leading followers of Gandhi's ideology were Jawaharlal Nehru, Vallabhbhai Patel, Abdul Ghaffar Khan, Maulana Azad, and others. Intellectuals such as Rabindranath Tagore, Subramania Bharati, and Bankim Chandra Chattopadhyay spr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angel Investor
An angel investor (also known as a business angel, informal investor, angel funder, private investor, or seed investor) is an individual who provides capital to a business or businesses, including startups, usually in exchange for convertible debt or ownership equity. Angel investors often provide support to startups at a very early stage (when the risk of their failure is relatively high), once or in a consecutive manner, and when most investors are not prepared to back them. In a survey of 150 founders conducted by Wilbur Labs, about 70% of entrepreneurs will face potential business failure, and nearly 66% will face this potential failure within 25 months of launching their company. A small but increasing number of angel investors invest online through equity crowdfunding or organize themselves into angel groups or angel networks to share investment capital and provide advice to their portfolio companies. The number of angel investors has greatly increased since the mid-20th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychoacoustics
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system. It is the branch of science studying the psychological responses associated with sound including noise, speech, and music. Psychoacoustics is an interdisciplinary field including psychology, acoustics, electronic engineering, physics, biology, physiology, and computer science. Background Hearing is not a purely mechanical phenomenon of wave propagation, but is also a sensory and perceptual event. When a person hears something, that something arrives at the ear as a mechanical sound wave traveling through the air, but within the ear it is transformed into neural action potentials. These nerve pulses then travel to the brain where they are perceived. Hence, in many problems in acoustics, such as for Auditory system, audio processing, it is advantageous to take into account not just the mechanics of the environment, but also the fact that both the ear ...

Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an Acoustical engineering, acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing (sense), Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, ...

Loudspeaker
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. The driver is a linear motor connected to a diaphragm, which transmits the motor's movement to produce sound by moving air. An audio signal, typically originating from a microphone, recording, or radio broadcast, is electronically amplified to a power level sufficient to drive the motor, reproducing the sound corresponding to the original unamplified signal. This process functions as the inverse of a microphone. In fact, the ''dynamic speaker'' driver—the most common type—shares the same basic configuration as a dynamic microphone, which operates in reverse as a generator. The dynamic speaker was invented in 1925 by Edward W. Kellogg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-linear System
In mathematics and science, a nonlinear system (or a non-linear system) is a system in which the change of the output is not proportional to the change of the input. Nonlinear problems are of interest to engineers, biologists, physicists, mathematicians, and many other scientists since most systems are inherently nonlinear in nature. Nonlinear dynamical systems, describing changes in variables over time, may appear chaotic, unpredictable, or counterintuitive, contrasting with much simpler linear systems. Typically, the behavior of a nonlinear system is described in mathematics by a nonlinear system of equations, which is a set of simultaneous equations in which the unknowns (or the unknown functions in the case of differential equations) appear as variables of a polynomial of degree higher than one or in the argument of a function which is not a polynomial of degree one. In other words, in a nonlinear system of equations, the equation(s) to be solved cannot be written as a linea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
