Risk management is an important part of system assurance and it is widely used in safety-related system. Railway signal system is one kind of safety-related system and its most important goal is to guarantee the safety of railway system. The method based on risk management can find and solve the security issues of railway signal system more effectively. This paper introduces the basic conceptio...

In this study we investigated two patients with pure alexia, F.C. and L.D.S., in order to make inferences about how processes and levels involved in the early stage of visual word recognition are organized and how they can be selectively damaged. Moreover, we investigated whether pure alexia can be caused by different functional deficits. F.C. and L.D.S. were presented with tasks of letter proc...

Current methods for generating qualitatively different plans are either based on simple randomization of planning decisions and so cannot guarantee meaningful differences among generated plans, or require extensive user involvement to drive the system into different sections of the overall plan space. This paper presents a cost-effective method for automatically generating qualitatively differe...

Work is described which supports multi agent mixed initiative interaction between a task assignment or command agent and a planning agent Each agent maintains an agenda of outstanding tasks it is engaged in and uses a common representation of tasks plans processes and activities based on the notion that these are all constraints on behaviour Interaction be tween the agents uses an exchange of e...

Many researchers and clinicians take an ‘either, or’ position regarding factors responsible for change when conducting research. Qualitatively driven mixed methods privilege the qualitative approach offer opportunity to generate multi-dimensional material, permitting a more holistic insight into experiences that can be understood from combination of epistemological ontological stances. A qualit...
