Within the systems movement, several strands and different sub-movements have developed in the last two or three decades. One of them is the “critical systems approach” which opposes certain assumptions and methodological and practical implications of the so-called hard and soft systems approaches. The most essential characteristics of the approach are its critical standpoint against exclusion ...

Medical Virtual Patient Simulator (MedVPS) is a cutting-edge eLearning innovation for medical and other health professionals. It consists of a framework that supports various patient cases, tailored by interdisciplinary medical teams. Each virtual patient case follows the critical path to be followed for a specific patient in a hospital. MedVPS takes the student on a journey that enables the st...

In this paper we present an algorithmic approach to packing A-paths. It is regarded as a generalization of Edmonds’ matching algorithm, however there is the significant difference that here we do not build up any kind of alternating tree. Instead we use the so-called 3-way lemma, which either provides augmentation, or a dual, or a subgraph which can be used for contraction. The method works in ...

In cases where usability is a mission critical system quality it is becoming essential to know whether an evaluation study has identified the majority of existing defects. Previous work has shown that procedures for estimating the progress of evaluation studies have to account for variation in defect visibility; otherwise, harmful bias will happen. Here, a statistical model is introduced for es...

The paper investigates the effects of technology scaling on area/delay characteristics of registertransfer level (RTL) designs. Based on experimental modeling of RTL components and interconnect, whose feature sizes have been scaled down from 1.5 m to 0.25 m, we evaluate the critical path delay and area of several data-paths and report on efficiency of layout and RTL optimization techniques at t...
