In this paper, we first build a simple model with firm heterogeneity that features input and output tariffs in firms’ production decisions. We show that tariff reduction, due to trade liberalisation, has different effects on firms’ profit. Input tariff reduction generates a cost‐saving effect which benefits firms whilst output tariff reduction results in a competition effect which may hurt domestic...
Automatic measuring and calculating methods for horizontal tank capacity are presented, and the tank guiding math model is derived. The tank can be measured automatically by total station base on the guiding model, and the NURBS is used to describe the surface of the tank. A software system, for horizontal tank capacity automatic measuring and calculating, is developed. The testing experiment of measuring...
