Various studies on request patterns in P2P networks have confirmed the existence of the interest-based clusters [11, 12]. Some P2P networks that exhibit the small-world phenomenon contain clusters of peers that frequently communicate with one another [17]. The existence of interest-based clusters opens up the possibility of more efficient routing. In this paper we consider the problem of design...

Monitoring the system environment is a key functionality of a selfadaptive system.Monitoring requirements denote the information a self-adaptive system has to capture at runtime to decide upon whether an adaptation action has to be taken. The identification of monitoring requirements is a complex task which can easily lead to redundancy and uselessness in the set of information to be monitored ...

background and objectives: nowadays, the use of educational models to determine the causes of rejection of health-related behaviors has been on theincrease. health belief model is one of the models during the past years has been considered. therefore, the aim of this study was to measure health belief model constructs in preventive behavior about self-medication in pregnant women in the city of...

Particle filter-based approaches have proven to be capable of efficiently solving the self-localization problem in RoboCup scenarios and are therefore applied by many participating teams. Nevertheless, they require a proper parametrization – for sensor models and dynamic models as well as for the configuration of the algorithm – to operate reliably. In this paper, we present an approach for opt...

social interest is human phenomenon which can be considered as structure of personality in psychology. this descriptive correlation study aimed to investigate self efficacy, social acceptance and locus of control as predictors of social interest. this was correlational study. the sample consisted of 153 boys and 147 girls who were studying at private middle schools. multistage cluster sampling ...

background and aim: nosocomial infections have been always among the major problems of healthcare delivery systems. the operating room is an appropriate place for causing severe nosocomial infections. knowledge of infection control guidelines and standards is the key to infection prevention. this study was conducted to investigate nurses’ knowledge and self-efficacy regarding the principles of ...

Autonomic Computing is a promising new concept in system development. It aims to (i) increase reliability by designing systems to be self-protecting and self-healing; and (ii) increase autonomy and performance by enabling systems to adapt to changing circumstances, using self-configuring and self-optimizing mechanisms. This paper discusses the type of system architecture needed to support such ...

The dynamic behaviour of a mechatronic system can be influenced and optimized in many different ways. One way is to use reactive systems that process measurements of the real system and compute control vectors using a preprogrammed stimulus-response behaviour. The optimization is performed indirectly or by learning procedures which will assess a possible success or failure of the real system. A...
