Speculative design is a subsidiary field of critical practice. It generally involves developing scenarios based on central object, often prototype. Because it concerned with alternative present and future states, many acknowledge the potential speculative for raising discussion public engagement science, technology, society. In this article, we ask how analogy to thought experiments highlights ...

surface roughness of engineering parts is very significant property that effectively influences on the wear and fatigue strength. there are many methods for improving surface quality of engineering parts such as grinding, lapping and honing. one of the methods for improving surface quality is roller burnishing. roller burnishing improves surface quality of engineering parts by means of cold wor...

As experimentation in the behavioral and social sciences moves from brick-andmortar laboratories to the web, new opportunities arise in the design of experiments. By taking advantage of the new medium, experimenters can write complex computationally mediated adaptive procedures for gathering data: algorithms. Here, we explore the consequences of adopting an algorithmic approach to experiment de...

Nowadays, the internet and social networks become more popular than ever. People in all ages use the internet and communicate by that. One of the most terrible events in our daily life is to disconnect from the internet and lose the connections. It may also influence on the economics; so the sustainability in this area is necessary. Internet service provider companies are the executors of selli...
