The paper considers the importance of knowledge management in the new economy, and focuses on the concept of knowledge audit and its need for developing and monitoring the knowledge management implementation. A special focus is made on knowledge audit concept and the approaches and processes proposed and used in practice. The paper highlights also some tools utilized in knowledge audit and the ...

This paper deals with well-defined design criteria for ultra low power two stage CMOS operational transconductance amplifiers (OTAs) with simple yet robust implementation in nm dimension. A simple design approach which allows electrical parameters to be univocally related to each circuit element and biasing values for low frequency applications is presented.The operational transconductance ampl...

Energy efficiency in buildings and facilities has become an important part of the efforts for reducing environmental pollution. In order to develop strategies for efficient allocation of energy resources aimed at reducing power consumption, certain electrical quantities needed for analysis must be measured and monitored. In this paper, we propose a low-cost architecture of the remote electrical...

The power chain of autonomous devices consists of an energy scavenger, power converter and energy storage system. The interaction between a piezoelectric vibration energy scavenger, the power converter and the energy storage system is investigated. A system level approach, including mechanical and electrical domains, is pursued for impedance matching from mechanical domain to electrical domain ...
