In this study we investigate Spot electricity price forecasting performance of Autoregressive-GARCH models on Indian spot electricity price series. Hourly spot electricity price data for each of the five regions of Indian Electricity market from 1st of October 2010 to 15th November 2013 is used for the study to evaluate forecasting performance of the calibrated models. The conditional mean and conditional variance equations are estimated and one-step-ahead forecasts with a rolling window is performed. The fact that India being the only country in the world having power exchanges in-spite of demand outstripping supply and peak power shortage even to this day, further emphasizes the significance and criticality of spot electricity price forecasting from a power market participant's perspective and its practical relevance for Open access consumers in India. © 2016 Elsevier Ltd.

In networking and multimedia technologies the digital video contents over the web availability is growing at a scare speed. By using many different devices the huge amount of videos can be played and downloaded from everywhere. The tremendous success of websites like YouTube, Google and iTunesvideos are based on the popularity where people can upload and download any videos. In such scenario, a tool for performing video browsing would be really appreciated. To overcome the browsing the video files today many indexing, techniques are proposed. In recent years video content management and mining has become more important. This is because of increasing amount of digital video system. The amount of audio/video data produced is rapidly increasing due to various digital equipments. Here a new mechanism is proposed in this work which implements a population based clustering mechanism for clustering and efficient video retrieval. © 2006-2016 Asian Research Publishing Network (ARPN).

Firms across the globe have adopted e-commerce (EC) in their operations and have reaped benefits thereof. While firms in technologically developed countries like US and UK has deployed EC to its advantage, whereas firms in developing countries like India failed to follow the suit. Though it has been widely acknowledged by the researchers that the adoption of EC by businesses in developing countries is an important economic indicator of growth; many firms in India still have not realized the potential benefits of EC. This study examines the existing status of EC in India and reviews the available literature on E-commerce adoption in India and puts forth opportunities for future research. The study might serve as a starting point for further research in e-commerce in India. © Springer Science+Business Media, LLC 2010. Source

Renewable and Sustainable Energy Reviews | Year: 2016

This paper examines the stationarity properties of the renewable-to-total electricity consumption ratio. For this purpose we use Becker et al.'s (2006) flexible Fourier stationarity test as a benchmark, and the recent advanced Fourier ADF unit root test, for 90 countries, over the period 1980-2011. The results of the first test document the stationarity of the renewable-to-total electricity consumption ratio for 65 countries from different geographic areas, namely Africa, America, Asia-Pacific and Europe. However, when validated, the Fourier ADF test shows that the null hypothesis of unit root is rejected in all the cases, except for the United Kingdom. The fact that the stationarity in the share of renewable-to-total electricity consumption is documented by the new proposed, more powerful tests, does not necessarily mean that the renewable energy policies are ineffective, as the previous literature states. A wide range of elements might influence the stationarity or non-stationarity of this ratio. However, our findings are important from the modeling perspective, as the empirical studies on renewable energy can produce reliable results and use appropriate techniques for modeling and forecasting only if the stationarity or non-stationarity is correctly documented. © 2015 Elsevier Ltd.

Online recruitment research has time and again addressed the issue of lack of credibility of online job advertising media compared to traditional media such as newspapers and the issue of poor quality web design in E-recruitment. In this paper, the issues of lack of credibility and quality of E-recruitment channels have been addressed through the introduction of a) realistic job previews (RJP), b) company independent channels for advertising jobs online (for example Blogs), and c) podcasts for corporate previews in online job website design. Final year post-graduate students about to enter job market (N=457) took part in a 2×2×2 factorial experiment. The findings give distinct indications of the advantage of use of the above mentioned web design features on applicant perception of quality, credibility, and their subsequent development of organizational attractiveness and intention to apply for a job in the firm. Recommendations for practitioners have been highlighted through illustrated examples. © Copyright 2016 IGI Global. Source
