  • The surface treatment by physical method of jute fiber using air plasma was investigated. Fiber was treated by the atmospheric plasma with various conditions of power 50W and different treatment times (from 1 min to 7 min). After treatment, the characteristics of fiber changed remarkably and fiber surface observed by SEM analyze showed a better morphology for adhesion. The result showed that tensile strength and Young’s modulus of jute fiber were slightly improved, however there was a remarkable improvement interface adhesion between fibers and polypropylene (PP) resin.

  • Data set weights are used to adjust for sampling and response rates, and to provide estimates of Wisconsin’s total household population using the sample data. A new procedure for developing data set weights was used with the 2008 Family Health Survey. The 2008 FHS sample included only landline telephone numbers, but ever-increasing numbers of people are using only cell phones, with no landline telephone service. Researchers are learning that the characteristics of cell-phone-only users differ from characteristics of people who use landline telephones.

  • Adsorption by activated red mud (ARM) is investigated as a possible alternative to the conventional methods of Cr(VI) removal from aqueous synthetic solutions and industrial effluents. Adsorption characteristics suggest the heterogenous nature of the adsorbent surface sites with respect to the energy of adsorption. Various factors such as pH, contact time, Cr(VI) concentration, amount of adsorbent, and temperature are taken into account, and promising results are obtained.

  • Each household member records spending for the same two diary weeks, so we must pool observations across households to study expenditures over an entire month. Given that distance from payday is orthogonal to household characteristics, this pooling should not bias our estimate of the relationship between distance and spending.8 We impose a number of sample restrictions. People paid weekly are excluded, because every diary week includes a payday for these individuals.

  • It’s been over 10 years since I was first introduced to R. Back then, I was a young product development manager at DoubleClick, a company that sold advertising software for managing online ad sales. I was working on inventory prediction: estimating the number of ad impressions that could be sold for a given search term, web page, or demographic characteristic. I wanted to play with the data myself, but we couldn’t afford a piece of expensive software like SAS or MATLAB. I looked around for a little while, trying to find an open-source statistics package, and stumbled on R.

  • Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the selectivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying.
