In an increasingly competitive environment, technical innovation in products and processes is by a vast number of manufacturing companies regarded as one of the most powerful enablers to differentiate from competitors and achieve competitive advantage. Accordingly, some manufacturing companies spend significant amounts of investments in innovation projects. In this paper, we examine the relationsh
In this paper, we investigate the impact of power amplifier (PA) nonlinear distortion in pre-coded multi-user large antenna or massive MIMO downlink systems. First, detailed signal and system models are derived for the received signal at single-antenna user equipment (UE) under channel-aware linear precoding in the base-station combined with behavioral models for the individual PA units, covering
The utilization of analytical/numerical techniques and methodologies within product development and design is seldom discussed in the literature. This leads to a loss of a holistic perspective on product development and design. The exclusion of analysis methods and techniques implies that their impact on the development/design procedures is considered negligible and is not regarded as a constituen
Decades of reforms focused on the deregulation of markets, have lead to disaggregation, competition and weakened political control. Today, the Western world is struggling to develop models to improve coordination: Whole-of-Government (WG) reforms are implemented. These reforms are focused in particular on the wicked issues that tend to appear in the boundaries between public and private, between p
The paper forms part of the presentation of the results from a resarch projct looking into socio-economic and environmental aspects of the HIV/ADIS epidemic. The project focuses on Tanzania with a special refernce to Karagwe and Muleba districts in Kagera Region and Makete District in Iringa Region. In this report a more aggregate level is investigated, however. In demographic terms changes in imp
The power consumption is becoming a major obstacle in future circuit design. Referring to Moore's law, by adding more functionality in an exponential way, we will also increase the total power consumption in the same pace. VLSI design has traditionally been concerning the dynamic power consumption as the limiting factor in low power system design. Today, when the feature sizes are in the nano-mete
Solid Oxide Fuel Cells (SOFCs) are widely studied for their advantages specially at high temperatures. The microscopic chemical reactions that occur in the cells have a strong influence on the cell performance although not much research has been done in this field yet. In order to do so, a numerical model of the microstructure of the electrodes, where the reactions take place, is needed. Different
