Can the Subaltern Speak

To improve the performance of particle image velocimetry in measuring instantaneous velocity fields, direct cross-correlation of image fields can be used in place of auto-correlation methods of interrogation of double- or multiple-exposure recordings. With improved speed of photographic recording and increased resolution of video array detectors, cross-correlation methods of interrogation of successive single-exposure frames can be used to measure the separation of pairs of particle images between successive frames. By knowing the extent of image shifting used in a multiple-exposure and by a priori knowledge of the mean flow-field, the cross-correlation of different sized interrogation spots with known separation can be optimized in terms of spatial resolution, detection rate, accuracy and reliability.

The Fortune at the Bottom of the Pyramid: Eradicating Poverty through Profits Pearson Education Inc., Wharton School Publishing, Upper Saddle River, New Jersey, 2004; Pages: 432; Price: US $ 29.99; ISBN: 0-13-146750-6. The treasure lying at the bottom of the world's economic pyramid, attracts companies with unimaginable prospects and profits. The economic pyramid of the world contains more than 400 crores of population at the bottom whose earnings and spendings per capita are low, but as an aggregate, are much larger than they are perceived to be. Hence, it is high time for the corporate managers to make an effort to locate the Alibaba's treasure lying hidden at the Bottom of the Pyramid (BOP). Broadly, the characteristics and spending patterns of the BOP segment are different as compared to the other segments of the society. In the high and medium range markets, consumers are able to buy bigger packages of consumables such as a 10 kg packet of detergents so that they need not shop frequently. But low-end BOP consumers do not have so much disposable cash to buy in bulk and store. Hence, it is suggested that this segment be provided with "single serve" packages. Already in India, 30% of personal care and other consumables such as shampoo, tea, and cold medicines are sold in single serve packages and most single serve packages are priced at one rupee. Hindustan Lever Limited offers Clinic Plus shampoo priced at 50 Paisa. The major differences between the Bottom of the Pyramid and the Top of the Pyramid markets are differences in buying habits and cultural differences. The Bottom of the Pyramid is characterized by a low brand consciousness due to low economic position, and is mostly need driven. Major emerging BOP markets in the world, including China, India, Mexico, Russia, Brazil, South Africa, Thailand, Turkey and Indonesia, with a combined population of about 300 crores, represent 70% of the world BOP population. Such a huge jumbo size BOP market promises intense marketing opportunities for the companies. THE BOOK UNDER REVIEW Part 1 of the book emphasizes the development of an appropriate framework for the active engagement of the private sector at the BOR It provides the basis for a profitable win-win situation for all stake holders involved in the process of catering to BOP markets. Part 2 describes 12 cases, in a variety of businesses where BOP is becoming an active market and is bringing benefits to its customers far beyond offering just products. Part 3 contains stories in video form-an attempt to present the prospects and prosperity underlying the BOP markets, and to bring the BOP markets into limelight. Around 100 hrs of video was collected as part of the research. The book specifies workable solutions for serving huge population lying at the bottom of the world's economic pyramid. Even with NGOs working tirelessly and government support and international aid being circulated heavily, the problem of poverty still persists. According to the author, the main reason for this situation is that the private sector, which is huge and potentially capable of solving any problem in the world, is practically not involved. The concept of 'Bottom of the Pyramid" is explained in this book. The World's Economic Pyramid contains wealthy people at the top with high spending capacities and habits. But the size of this segment is very small i.e., only about 7.5 to 10 crores of 600 crores plus population, whereas more than 400 crores of population live at the bottom of the pyramid earning less than $2 per day and in India alone around 40 crores of people earn less than Rs. 90 per day. The author opines that, to effectively serve this BOP market, instead of old and tried solutions, continuous innovation and a paradigm shift in the thinking process of the private sector is needed. THE BOOK PRESENTS CASES OF COMPANIES THAT ARE INVOLVED IN BOP MARKETING * The Solar Electric Light Fund (SELF): It established the Solar Electric Light Company (SELCO) in 1995 to market, install, and serve the Solar Home Systems (SHS) in south India. …

This letter reports on a contrast-based ultrasonic particle imaging technique (echo PIV) for measuring multicomponent velocity vectors in opaque flows with excellent temporal (up to 0.5ms) and spatial (up to 0.4mm) resolution. Ultrasound contrast microbubbles are used as flow tracers, and digitally acquired rf data are converted into B-mode images for PIV analysis. Here, velocity fields from various flow patterns (including rotating and transient vortex flows) that are difficult to measure using other opaque flow methods such as ultrasound Doppler or magnetic resonance imaging are measured using echo PIV. This nonintrusive technique should be a promising addition to opaque flow diagnostics.

Real time multicomponent echo particle image velocimetry technique for opaque flow imaging

We have recently developed an ultrasound-based velocimetry technique, termed echo particle image velocimetry (Echo PIV), to measure multi-component velocity vectors and local shear rates in arteries and opaque fluid flows by identifying and tracking flow tracers (ultrasound contrast microbubbles) within these flow fields. The original system was implemented on images obtained from a commercial echocardiography scanner. Although promising, this system was limited in spatial resolution and measurable velocity range. In this work, we propose standard rules for characterizing Echo PIV performance and report on a custom-designed Echo PIV system with increased spatial resolution and measurable velocity range. Then we employed this system for initial measurements on tube flows, rotating flows and in vitro carotid artery and abdominal aortic aneurysm (AAA) models to acquire the local velocity and shear rate distributions in these flow fields. The experimental results verified the accuracy of this technique and indicated the promise of the custom Echo PIV system in capturing complex flow fields non-invasively.

Development of a custom-designed echo particle image velocimetry system for multi-component hemodynamic measurements: system characterization and initial experimental results.

In this paper, we argue that there are patterns of innovation occurring in less economically developed countries (LEDCs) that have been historically overlooked by the innovation studies literature, including the literature on innovation systems and the triple helix. This paper briefly surveys cases in agriculture, banking, biomedicine and information and communications technologies that demonstrate organizational, scientific and technological innovation in Africa, South Asia, and Brazil. In particular, we track new developments in two distinctive patterns within LEDCs: (1) civil society as a site of innovation and; (2) innovation through appropriation. By systematically uncovering patterns of innovation in LEDCs, science and technology policy scholars may make new theoretical gains in innovation studies that can potentially contribute to innovation policies in the global South.
