The double-alternative, double-start experimental apparatus: A new procedure for measuring preference

A New Apparatus for Measuring Surface Tension

Surface tension is probably one of the most difficult phenomena to measure. Although a great deal of ingenuity has been spent for almost a century in devising accurate techniques, the figures obtained deviate more from each other for the same substance, according to different authors, than any other constant characterizing the substance. I t is well ,known tha t the two classes of methods of me...

Measuring The Quality Of Natural Lighting In A Building With Double Skin Façade (Dsf)

Lately, a double skin façade (DSF) has been increasingly popular as an aesthetic and shading device. A façade with a secondary skin is employed in buildings to let natural light flow into the building without glare and heat. The purpose of this study is to examine the performance of secondary skin in buildings and to investigate the level of natural lighting in buildings that meets visual comfo...

Double preference relations for generalised belief change

Many belief change formalisms employ plausibility orderings over the set of possible worlds to determine how the beliefs of an agent ought to be modified after the receipt of a new epistemic input. While most such possible world semantics rely on a single ordering, we investigate the use of an additional preference ordering—representing, for instance, the epistemic context the agent finds itsel...

Reducing Start-up costs for New Firms: The Double Dividend on the Labor Market.∗

Starting a firm with expansive potential is an option for educated and high-skilled workers. This option serves as an insurance against unemployment caused by labor market frictions and hence increases the incentives for education. We show within a matching model that reducing the start-up costs for new firms results in higher take-up rates of education. It also leads, through a thick-market ex...
