Corporate Dynamic Eco‐Innovation Capability and Carbon Emission Reduction: Evidence From African Listed Firms With the Role of Institutional Pressures

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite the global emphasis on simultaneous achievement of higher growth and lower pollution (green growth), the dynamic link between eco‐innovation and CO2 emissions remains inadequately understood globally and specifically in Africa, with a complex and diverse institutional and regulatory landscape.

QR-decomposition of a matrix

, 2015
Práce je rozdělená do čtyř kapitol. První kapitola se zabývá obecnými definicemi a poznatky, bez nichž by bylo obtížné QR-rozklad pochopit. Druhá kapitola se věnuje prvnímu způsobu QR-rozkladu. Jedná se o Gramův-Schmidtův ortogonalizační proces.

New parallel strategies for block updating the QR decomposition

, 1995
Parallel strategies are proposed for updating the QR decomposition of an m × n matrix after adding k rows (k ≫ n). These strategies are based on Givens rotations and are found to complete the updating in fewer steps by comparison to a recently published ...
