This paper introduces broad concepts of vulnerability, food security and famine. It argues that the concepts and theories driving development and implementation of vulnerability assessment tools are related to their utility. The review concludes that socio-geographic scale is a key issue, and challenge. It analyses three vulnerability assessment (VA) methods, using Ethiopia as a case study. Fac...

Bubbling to the surface: Microscale gas bubbles can be generated in a microfluidic device by simultaneously injecting CO(2) and a dispersion of particles whose hydrophobicity increases as the pH value decreases. The CO(2) dissolves rapidly out of the bubbles, which shrink, and render the dispersion increasingly acidic. This drives the particles to the bubble surface where they form a type of "a...

This paper summarizes the principles and methods of establishing the comprehensive evaluation index system of urban public transport development level, and analyzes how to establish the evaluation index system by using the analytic hierarchy process. Then, using the fuzzy comprehensive evaluation method to develop the public transportation in Xi'an Shaanxi China, and to find out the shortcoming...

The Analytic Hierarchy Process as an aid to decision makers has gained in popularity over the years. Recently the procedure has been generalised into the Interval Analytic Hierarchy Process. Rather than select a precise ratio for the comparisons between the alternatives offered to the decision maker an interval is proposed. One popular strategy in examining this problem is to adopt a simulation...

Recent advances in surface engineering and soft lithography provide tools to fabricate patterned surfaces and microfluidic devices with dimensions comparable to the sizes of single mammalian cells. These technologies enable the studies of individual cells on spatially well-defined, patterned surfaces, and in contact with patterned liquid media. They provide information about cells impossible to...

Résumé. Une session d’analyse OLAP peut être définie comme une session interactive durant laquelle un utilisateur lance des requêtes pour naviguer dans un cube. Très souvent, choisir quelle partie du cube va être naviguée par la suite, et, de ce fait, concevoir la prochaine requête, est une tâche difficile. Dans cet article, nous proposons d’utiliser ce que tous les utilisateurs du système OLAP...

Data organization is a difficult and essential component in cultural heritage applications. Over the years, a great amount of archaeological ceramic data have been created and processed by various methods and devices. Such ceramic data are stored in databases that concur to increase the amount of available information rapidly. However, such databases typically focus on one type of ceramic descr...
