This paper addresses the problem of the evaluation of people counting systems. The relation between the real people number and the output of the people counting system is used to motivate the computation of the maximum number of people as a scenario and geometry specific quantity which supports the evaluation of the system output. Based on the camera field-of-view we determine the maximum numbe...

Materialized views, especially views involving aggregation, are often used in environments such as data warehouses to speed up the evaluation of complex queries. Because the views can be quite complex, as changes are made to the underlying base data it is usually better to incrementally maintain a view by propagating changes to base data onto the view than to recompute the view from scratch. Gr...

Existing microstructure literature cannot explain the empirical evidence that bid-ask spreads can decrease with information asymmetry and ignores either information asymmetry or inventory risks. We develop a market making model that highlights the asset pricing impact of market makers’ capability of making offsetting trades in markets where both information asymmetry and inventory risk are sign...

Given a ring A and an A-coring C we study when the forgetful functor from the category of right C-comodules to the category of right A-modules and its right adjoint − ⊗A C are separable. We then proceed to study when the induction functor − ⊗A C is also the left adjoint of the forgetful functor. This question is closely related to the problem when A → AHom(C, A) is a Frobenius extension. We int...

Recently, there have been several attempts to generalize the counterfactual theory of causal explanations mathematical explanations. The central idea these is use conditionals whose antecedents express a impossibility. Such countermathematical are plugged into explanatory scheme and—so hope—capture Here, I dash hope that simply parallel In particular, show based on countermathematicals suscepti...
