Gate-capacitance extraction from RF C-V measurements

In this work, a full two-port analysis of an RF C-V measurement set-up is given. This two-port analysis gives insight on the limitations of the commonly used gate capacitance extraction, based on the Y/sub 11/ parameter of the device. It is shown that the parasitics of the device can disturb the extracted gate capacitance and a new extraction scheme, based on the Z-matrix, is introduced that eliminates the effect of these parasitics. Measurement results prove the validity of this new extraction scheme, under different conditions

Strategic R&D with Knowledge Spillovers and Endogenous Time to Complete

It is shown that asymmetry in R&D efficiency between firms is an important factor determining feasibility of the preemption and attrition scenarios in competitive R&D with time to build. Scenarios of attrition and preemption games are most likely to occur when competitors have similar R&D efficiencies. In case of largely asymmetric firms the games of attrition and preemption are very unlikely, thus the R&D duration choices of firms are determined by the actual trade-off between the benefits of earlier innovation and the costs of faster R&D project completion.R&D Investment;Competition;Preemption;Attrition

PRODUCTION OF PROBIOTICS BY IN VITRO ENRICHMENT OF BENEFICIAL MICROORGANISMS FROM HUMAN OR ANIMAL MICROBIOTA

The present invention is directed to a method of treating a dysbiosis in a mammal, preferably a human, by taking a sample of the micro-organisms that are causative of the dysbiosis, whereafter said sample is enriched in vitro for healthy bacteria, after which the sample is replaced

Parse-tree annotations meet re-engineering concerns

We characterise a computational model for processing annotated parse trees. The model is basically rewriting-based with specific provisions for dealing with annotations along the ordinary rewrite steps. Most notably, there are progression methods, which define a default for annotating the results of rewriting. There are also access methods, which can be used in the rewrite rules in order to retrieve annotations from the input and to establish annotations in the output. Our approach extends the basic rewriting paradigm with support for the separation of concerns that involve annotations. This is motivated in the context of transformations for software re-engineering where annotations can be used to implement concerns such as layout preservation and reversible preprocessing
