Providing assurances for self-adaptive systems is challenging. A primary underlying problem is uncertainty that may stem from a variety of different sources, ranging from incomplete knowledge to sensor noise and uncertain behavior of humans in the loop. Providing assurances that the self-adaptive system complies with its requirements calls for an enduring process spanning the whole lifetime of ...

Composition, change and complexity have attracted ev- eryone’s attention towards Self-Adaptive systems. These systems, inspired by the human body, are capable of adapting to changes in the inner and outer environment. The main objective of this study is to achieve a more con- venient availability for e-banking services in the payment switch, using self-healing systems and focusing on the failur...

the error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. global positioning system is the best aiding system in this case. in this paper we first simulate a gps and ins; then simulate tightly integration and finally review adaptation method of kalman filtering a fuzzy adaptive kalma...

this paper presents a new observer-based control scheme for a class of nonlinear systems. in the proposed method, nonlinear observer and twisting algorithm controller are employed to realize a sensor-less control strategy for complex systems which makes use of non measurable process information instead of installing as many sensors as possible. due to lack of availability of the complex system ...

this paper presents a novel indirect adaptive power system stabilizer (pss) via a developed synergetic control methodology and fuzzy systems. fuzzy system is utilized in an adaptive scheme to estimate the system using a nonlinear model. the synergetic control guarantees robustness of the controller and makes the controller easy to implement because of using a chatter free continuous control law...

The paper introduces QuizGuide, an adaptive system that we developed to help our students select the most relevant self-assessment quizzes. QuizGuide uses adaptive navigation support to show every student which topics are currently most important and which require further work. Despite relatively simple user modeling and adaptation techniques used in QuizGuide, the system has achieved a remarka...

EUNITE the European Network of Excellence on Intelligent Technologies for Smart Adaptive Systems (http://www.eunite.org) is launched a competition ”Modeling the Bank’s Client behavior using Intelligent Technologies”. In this work we propose a Case Based Reasoning system whose case database consists of a Self-Organizing Map (SOM). A simple system but efficient, fast and adaptive.

A 1-adaptive self-stabilizing system is a self-stabilizing system that can correct any memory corruption of a single process in one computation step. 1-adaptivity means that, if in a legitimate state the memory of a single process is corrupted, then the next system transition will lead to a legitimate state. Then, in one step the system recovers a correct behavior. Then 1-adaptive self-stabiliz...

Adaptive geovisualization has been marked as a research front that addresses design issues of a user-centered geovisualization system. By constantly keeping trace of user actions, a highly adaptive geovisualization system is able to predict the behavior of its end user and accordingly provide him with the visualization that suits best his personal taste and need. An adaptive geovisualization sy...
