An arrangement of hyperplanes in E'' is a "plaid" provided its hyperplanes form no multiple flats of intersection and lie in parallel families that are in general position. We develop some geometrically natural formulas for the number of r-faces that are formed by such an arrangement.

The period since World War Two has been marked by a great deal of civil war. Most of these civil wars have been ethnic civil wars. This paper presents a one shot game of ethnic conflict. The government is endowed with goods that it distributes among ethnic groups. The government is initially controlled by one of the groups and other factions can expend resources to fight for control of the gove...

This paper provides a new estimation of an international poverty line based on a Bayesian approach. We found that the official poverty lines of the poorest countries are related to the countries’ mean consumption level. This new philosophy is to be compared to the previous assumptions made by the World Bank in favour of an absolute poverty line. We propose a new international poverty line at $1...

Speech recognition has advanced considerably, but has been limited almost entirely either to situations in which close speaking microphones are natural and acceptable (telephone, dictation, command&control, etc.) or in which high-quality recordings are ensured. Furthermore, most recognition applications involve controlled recording environments, in which the user turns the recognition event on ...

This paper describes the development and implementation of a dynamic positioning system for Remotely Operated underwater Vehicles (ROVs) which is based on a mechanical Passive Arm (PA) for position measurement. The system, named DPSROV, is suited for tasks which require precise positioning within a limited range around a working site. The DPSROV was conng-ured aiming at easy installation in mos...

Precise point positioning (PPP)-based deformation monitoring scheme is presented for the use in mining deformation monitoring. Within the solutions of daily observation, outliers are detected and removed to avoid any potential misinterpretation of the results and then the deformation can be extracted by the coordinate differences between the two consecutive solutions. Meanwhile, because of the ...
