We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...

In this paper we present several proofs on the extension of M. Riesz fractional integration and di¤erentiation to the contexts of spaces of homogeneous type and measure metric spaces with non-doubling measures. 1. Introduction, some de…nitions, and a basic lemma Professor M. Ash asked me to write a survey article on some of the results that Stephen Vági and I obtained in the nineties on fractio...

Each year, twice as many people die in Europe from hospital acquired infections than from road accidents. These infectious diseases have developed antibiotic resistance and spread despite the best efforts of staff, mainly through textiles like bed linen. But the technology developed by a European research project helps fight back against the so-called superbugs, by using a revolutionary nanotec...

Introduction The elements of design serve as a foundation for the development and creation of all textiles and clothing products, including fabrics for interior spaces. Throughout history artisans and designers have utilized the elements of design in a variety of ways to create a certain aesthetic. Across the disciplines, the elements of design: line, space, shape, form, texture, and color are ...

Common cotton textiles are hydrophilic and oleophilic in nature. Superhydrophobic cotton textiles have the potential to be used as self-cleaning fabrics, but they typically are not super oil-repellent. Poor oil repellency may easily compromise the self-cleaning property of these fabrics. Here, we report on the preparation of superoleophobic cotton textiles based on a multilength-scale structure...

This paper describes finite element analysis of compaction for dry textiles during preform manufacture. The models are generated using procedures encompassed in our TexGen textile modeling schema. Meshing and material property allocations are performed automatically, including definition of material orientations for each of the elements. Tow elements are modeled using a transverse isotropic mod...

The simulation of the Liquid Composite Moulding process is an important step for the manufacturing of composites with textile reinforcements. However, its fast direct numerical simulation is impossible on the microscale due to computational complexity reasons. We have to resort to the macroscale instead. Here, an essential task is the fast and accurate prediction of the permeability of textile ...

Paper and textiles have been used ubiquitously in our everyday lives, such as books and newspapers for propagating information, clothing and packaging. In this perspective, we will summarize our recent efforts in exploring these old materials for emerging energy and environmental applications. The motivations and challenges of using paper and textiles for device applications will be discussed. ...

Interest in antibacterial textiles has been increasing recently. Different kinds of antibacterial textiles with different effectivity are being sold in the market. The influence of time on the antibacterial activity of such textiles is not known generally. The goal of this research was to study the mechanism of commercially available antibacterial agent meant for cotton with regard to the influ...
