The Greenhouse Effect Most people recognize global warming, but fail to recognize what is really behind it. In addition, most people would also recognize the concept of the greenhouse effect, or at least some variation of it. The fact is that the greenhouse effect is what leads to global warming, but how does that happen? Let’s start with some historical analysis of the topic. The greenhouse effect (or at least a rough version) was originally thought of and recognized by Jean Baptiste Joseph Fourier in 1824. Starting with the concept that the earth’s atmosphere acts as an insulator for the sun’s energy and heat, Fourier’s idea was recognized and theorized into what is now the known as the greenhouse effect. A more thorough description requires…

Introduction In color reproduction, gamut or the color gamut is a certain complete subset of colors, which can be accurately represented in a given circumstance such as given color space [1]. In another words gamut literally means the total range of possibilities that can be accomplished from red, green and blue (RGB) for a particular device [2]. If certain color cannot be reproduced accurately there is a way how to calculate the color difference by adequately describing the color by numerical…

2. QPSK: When a data is transmitted using BPSK technique the channel bandwidth required is 2fb. The QPSK technique reduces that bandwidth to fb. It is a multilevel phase modulation. In this two successive bits in a bit stream are combined together to form a message and each message is represented by distinct value of phase shift of a carrier. The QPSK signal is represented as. Since there are 4 phases it is called as 4-PSK or Quadrature PSK systems [6][7]. 3. QAM: QAM improves the noise…

method without using any Fourier transform or filters, 2nd; AWT was found more straightforward application and a superior alternative of STFT providing satisfactory information of the T-F characteristics. Ref. [16] explained a comparison between STFT and AWT, shown in fig. 16. Instead of STFT with uniform T-F resolution, AWT does not compromise on either temporal or frequency resloution and provides fine…

Drug content in cocrystals was determined by taking equivalent amount of the powder containing 10mg of levofloxacin, dissolved in 10mL of ethanol, shaken for 10-15 minutes and the volume was made up to 100mL using simulated gastric fluid (enzyme free) of pH 1.2. The samples were centrifuged and filtered through 0.45 µm filter, diluted suitably and analysed using UV-Visible spectrophotometer (Systronics, India) at λmax of 227nm. All observations were done in triplicate. Fourier Transform Infrared…

devices. The presence of harmonics in power system is a major concern to power engineers for many years. Harmonics lead to industrial plant downtimes and power losses. Harmonic is the signal whose frequency is a multiple integer of the fundamental frequency. The highly non-linear devices are the sources of harmonics. Harmonic analysis is used to calculate the impact of harmonic producing loads on a power system [1]. The effect of harmonics on power system can be in the form of power efficiency…
