It is believed that new types of computing machines will be constructed to exploit quantum mechanics for an exponential speed advantage in solving certain problems compared with classical computers 9.

This article discusses practical problems in connexion with the taking of sample surveys for demographic inquiries in undeveloped countries. The discussion is divided into three main topics, dealing ...

Networks are a popular tool for representing elements in a system and their interconnectedness. Many observed networks can be viewed as only samples of some true underlying network. Such is frequently ...

Researchers have observed the exploratory behavior of ants to inform the development of a more efficient mathematical sampling technique. In a paper published by the Royal Society, a team of Bristol ...

Small-scale quantum computers made from an array of interconnected waveguides on a glass chip can now perform a task that is considered hard to undertake on a large scale by classical means. Although ...

A number of potential sources can cause chronic flare and stack sampling issues. These issues in petrochemical and refining operations (Figure 1) are caused by poorly or inaccurate specified sampling ...

Material selection is seldom as easy as pulling an available tube from the stock room. Good sample transport system design incorporates various factors in material selection. These include surface ...
