IRJET-CUK Converter Based PV Module for Excitation Ff Synchronous MachineIRJET Journal
Vishant G. Naik , Santosh Singh Negi"CUK Converter Based PV Module for Excitation Ff Synchronous Machine", International Research Journal of Engineering and Technology (IRJET), Volume2,issue-01 April 2015.e-ISSN:2395-0056, p-ISSN:2395-0072. www.irjet.net
Abstract
The unavailability of fossil fuel and increasing demand for energy has pushed us towards finding alternative source of energy. The solar energy can be used for excitation of synchronous machine as an alternative source of energy. Due to increasing efficiencies and decreasing cost of PV cells, various MPPT algorithms have been implemented. In this paper a Cuk converter has been used in order to achieve constant excitation voltage which is required for exciting field winding of synchronous machine. MATLAB software has been used for simulation of both solar cell and Cuk converter which are modeled using sim power system blocks.

IRJET-Detailed Energy Audit in a Captive Cogeneration PlantIRJET Journal
D.Rajani Kant , B.Sudheer Prem Kumar, N.Ravi Kumar, R.Virendra,J.Suresh Babu " Detailed Energy Audit in a Captive Cogeneration Plant ", International Research Journal of Engineering and Technology (IRJET), Volume2,issue-01 April 2015.e-ISSN:2395-0056, p-ISSN:2395-0072. www.irjet.net
Abstract
The rate of exploitation of the energy resources has been expanding over time and resulted in reduction of fossil fuel reserves. Efficiency of all resources is crucial both in environmental and economic sense. Using energy inefficiently creates waste in all the world’s economies. It has environmental impacts with regional, local and global implications.The key object is to adopt energy management in every field in order to reduce the wastage of energy sources and cost effectiveness without affecting productivity and growth.
IRJET-Applications Of Social Media Analytics In Designing An Effective Market...IRJET Journal
Adarsh A, Astha Bhawsinka, Anuja Thakur "Applications Of Social Media Analytics In Designing An Effective Marketing Strategy.", International Research Journal of Engineering and Technology (IRJET), Vol2,issue-01 March 2015. e-ISSN:2395-0056, p-ISSN:2395-0072. www.irjet.net
Abstract
Social Media Analytics (SMA) is the emerging technique by which one can extract information from the unstructured data taken from various social media platforms to improve business, marketing, sales, etc. Social media is not just a marketing media, it has multiple touch-points in an organization such as customer service, sales, and human resource management. By using this information companies can keep proactive watch on the market sentiments and take preventive and corrective actions in real-time to boost their brand image, and therein, keep ahead of competition by winning customer loyalty. The detailed research analysis in marketing context using SMA is not evident in the literature, and also the results revealed that the effectiveness of marketing strategy can be increased exponentially by using SMA. This paper explains how SMA can be used at each stage to design an effective marketing strategy

Abstract
Two stage BJT amplifiers for very small signal amplification is presented in this work. With maximum 20V supply voltage and 6mV peak to peak input signal, a fraction of input signal 130uV goes to the first pre amplifier stage and produces an output signal of 11.25V peak to peak at the second stage. The overall gain of the circuit is 86538 times the small signal appearing across the input terminal of the first stage. The design circuit works best for input voltage swing from 100uV peak to peak till 6 mv peak to peak signal voltage. The variation of amplifier gain wrt Vcc is also analyzed. From 7V till 20V if Vcc is varied the gain linearly increases. Maximum gain of 65.24db without output distortion is obtained when the supply voltage is 20V with the least bandwidth. Minimum gain of 31db is obtained with the least 7V voltage supply but having the highest bandwidth. The output noise voltage is from 1.6uV/Hz till 270uV/Hz as supply voltage increases. The main objective of this work is to optimized and enhanced both gain and bandwidth of the amplifier for very small and low frequency signal amplification.
Evidence for the_thermal_sunyaev-zeldovich_effect_associated_with_quasar_feed...Sérgio Sacani
Using a radio-quiet subsample of the Sloan Digital Sky Survey spectroscopic quasar
catalogue, spanning redshifts 0.5–3.5, we derive the mean millimetre and far-infrared
quasar spectral energy distributions (SEDs) via a stacking analysis of Atacama Cosmology
Telescope and Herschel-Spectral and Photometric Imaging REceiver data. We
constrain the form of the far-infrared emission and find 3σ–4σ evidence for the thermal
Sunyaev-Zel’dovich (SZ) effect, characteristic of a hot ionized gas component with
thermal energy (6.2 ± 1.7) × 1060 erg. This amount of thermal energy is greater than
expected assuming only hot gas in virial equilibrium with the dark matter haloes of
(1 − 5) × 1012h
−1M that these systems are expected to occupy, though the highest
quasar mass estimates found in the literature could explain a large fraction of this
energy. Our measurements are consistent with quasars depositing up to (14.5±3.3) τ
−1
8
per cent of their radiative energy into their circumgalactic environment if their typical
period of quasar activity is τ8 × 108 yr. For high quasar host masses, ∼ 1013h
−1M,
this percentage will be reduced. Furthermore, the uncertainty on this percentage is
only statistical and additional systematic uncertainties enter at the 40 per cent level.
The SEDs are dust dominated in all bands and we consider various models for dust
emission. While sufficiently complex dust models can obviate the SZ effect, the SZ
interpretation remains favoured at the 3σ–4σ level for most models.
