The paper is devoted to the accuracy improvement of robot-based milling by using an enhanced manipulator model that takes into account both geometric and elastostatic factors. Particular attention is paid to the model parameters identification accuracy. In contrast to other works, the proposed approach takes into account impact of the gravity compensator and link weights on the manipulator elas...

Africa should industrialize. Without structural change it cannot sustain recent growth. Economies with more diverse and sophisticated industrial sectors tend to grow faster. But since 1980 Africa has deindustrialized. The paper shows that between 1975 and 2005 the size, diversity and sophistication of industry in Africa have all declined. An industrialization strategy containing two elements is...
