There is little question as to whether there good boring art, though its existence raises a number of questions for both the philosophy art and emotions. How can boredom ever be desideratum art? our standing commitments concerning nature aesthetic experience artistic value accommodate being bored constitute an appropriate mode engagement with work More broadly, how works whose very success requ...

The earliest bioeroded inorganic hard substrates in the Ordovician of Estonia appear in the Dapingian. Hardgrounds are also known from the Sandbian and Katian. Most of the bioerosion of inorganic hard substrates occurs as the boring Trypanites Mägdefrau, 1932 along with some possible Gastrochaenolites borings. North American hardground borings are more diverse than those in Baltica. In contrast...

The paper presents ways to reduce the vibrations of special cantilever boring bars mounted on spindle heads finishing and machines. Special are designed for machining holes in non-standard conditions, example, when deep with l/d>3 (l–hole length, d-hole diameter) or a discontinuous surface. results experiments theoretical developments, as well schemes experimental stands, presented. investig...

This paper presents empirical results that contradict the prevailing opinion that entity extraction is a boring solved problem. In particular, we consider data sets that resemble familiar MUC/ACE data, and report surprisingly poor performance for both commercial and research systems. We then give an error analysis that suggests research challenges for entity extraction that are neither boring n...

Ensuring the stability of shaft structure is one key technologies for application raise boring method. In process reaming through rock formations with water disintegration characteristics, impact gushing and drenching may induce partial collapse. To solve this problem, an intelligent temporary while-boring support technology proposed in paper. Firstly, main characteristics are introduced. Utili...

Boring is an operation which converts a knot or two-component link in a 3–manifold into another knot or two-component link. It generalizes rational tangle replacement and can be described as a type of 2–handle attachment. Sutured manifold theory is used to find lower bounds for the genus of knots obtained by boring split links and unknots. Bounds on the euler characteristic of essential planar ...
