    Ultrafast Analog Fourier Transform Using 2-D LC Lattice

    We describe how a 2-D rectangular lattice of inductors and capacitors can serve as an analog Fourier transform device, generating an approximate discrete Fourier transform (DFT) of an arbitrary input vector of fixed length. The lattice displays diffractive and refractive effects and mimics the combined optical effects of a thin-slit aperture and lens. Diffraction theories in optics are usually derived for 3-D media, whereas our derivations proceed in 2-D. Analytical and numerical results show agreement between lattice output and the true DFT. Potentially, this lattice can be used for an extremely low latency and high throughput analog signal processing device. The lattice can be fabricated on-chip with frequency of operation of more than 10 GHz

    Bioremediation of copper by xeric chlorophycean bioremediator, Chlorococcum hemicolum was investigated. The growth rates at various concentrations of Cu2+ were assessed in terms of protein level and 8 mg L-1 (37.67 % level in growth kinetics) is the tolerance limit. Absorption/adsorption kinetics was estimated after 240 hrs of Cu2+ treatments. Absorptions were higher than adsorption with maximum accumulation factor (AF) of 1.40. The Cu2+ concentration and absorption were linearly related (r = 0.99; p>0.01). Other biochemical parameters like total sugar, chlorophyll and carotenoids were also quantified to correlate the state of metabolism and these exhibited reduction due to heavy metal stress

    Low Cost Swarm Based Diligent Cargo Transit System

    Full text link
    The goal of this paper is to present the design and development of a low cost cargo transit system which can be adapted in developing countries like India where there is abundant and cheap human labour which makes the process of automation in any industry a challenge to innovators. The need of the hour is an automation system that can diligently transfer cargo from one place to another and minimize human intervention in the cargo transit industry. Therefore, a solution is being proposed which could effectively bring down human labour and the resources needed to implement them. The reduction in human labour and resources is achieved by the use of low cost components and very limited modification of the surroundings and the existing vehicles themselves. The operation of the cargo transit system has been verified and the relevant results are presented. An economical and robust cargo transit system is designed and implemented.Comment: 6 pages, 9 figures, 1 block diagra

    SWOT Analysis for opening of FDI in Indian Retailing

    Get PDF
    The retail industry in India is expected to grow at a rate of 14% by 2013. The first step towards allowing Foreign Direct Investment in Retail was taken in the year 2006. Since then 54 FDI approvals have been accepted by the government and the country has received cash inflow to the tune of about Rs 901.64 crore. Retailing consists of all business activities involving the sale of goods and services to ultimate consumers. Retailing involves a retailers traditionally a store or a service establishment, dealing with consumers who are acquiring goods and services for their own use rather than for resale. Wal-Mart, The Limited, Best Buy and other familiar organizations are retailers. Retailing is based more on whether the business deals directly with public. Retail banking, service stations local coffee shops are also retailers with the emergence of online retailing, retailers are no longer concerned about location of stores. E-retailing has emerged. Consumers are always hungry for modern ways of shopping. Indian retail sector is growing fast and its employment potential is growing fast. The retail scene is changing really fast. Retailers are rethinking their approaches towards the suppliers so that they can get the best pricing strategies for them. Retail sector in India is also catalyst for the growth of staling tactics of below the line marketing used by major retail players like Spencer, big bazaar, reliance fresh etc. For tapping customers by creating points of sales displays. So we can say that India is a rising star and going to be one of the fastest growing regions of the future. Key words: Foreign direct Investment, Retailing, GDP, Multinationals, Policies, and infrastructure development

    Demonetization of Higher Denomination Banknotes in India and Growth of Mobile Wallet Business Transactions

    Get PDF
    This paper will discuss the effect of the recent denomination policy of the Government of India on the growth of mobile wallet business transactions. The impact is not going to be same across the different sectors of the economy. The business units that have a larger cash component in their transactions will be affected harder, such as reality, construction, movie production, etc. This will lead to some correction in these markets. Whether these corrections results in reducing prices is something to be watched closely. Demonetization of high value currency notes in India will provide a big boost for mobile wallet in India. Reduction in cash transactions will help multiply digital and plastic transactions such as cheques, credit card and mobile wallets. Keywords: denomination, mobile wallets, online bankin
