Self-efficacy is a personal belief in one's capability to organize and execute courses of action required to attain designated types of performances. Often described as task-specific self-confidence, self-efficacy has been a key component in theories of motivation and learning in varied contexts. Furthermore, over the last 34 years, educational researchers from diverse fields of inquiry have us...

This paper exploits an innovative technique to improve performances related to localization, tracking and classification of objects in a video surveillance system. The developed strategy has been applied to the problem of interaction between objects, i.e. well tuned traditional algorithms can able to track and classify objects whenever they enter the scene well-isolated from the other moving ob...

The ASCENS project works with systems of self-aware, selfadaptive and self-expressive ensembles. Performance awareness represents a concern that cuts across multiple aspects of such systems, from the techniques to acquire performance information by monitoring, to the methods of incorporating such information into the design making and decision making processes. This chapter provides an overview...

The paper presents considerations regarding to design and simulation of two adaptive controllers (self-tuning controller with feedback and respectively reference compensation) with application to a power system. The self-tuning control strategy is applied for the excitation control of a synchronous generator. There are analyzed the performances of the both considered self-tuning control structu...

There are a number of models that were proposed in recent years for message passing parallel systems. Examples are the postal model and its generalization the LogP model. In the postal model a parameter h is used to model the communication latency of the message-passing system. Each node during each round can send a fixed-size message and, simultaneously, receive a message of the same size. Fur...

Mobile Adhoc Networks are type of wireless network which are infrastructure less, self organizing, highly mobile and quickly deployable. There is no central authority, the communication occur hop by hop based on cooperation among the nodes. Thus, secure routing protocols are needed which are robust and ensure that the nodes in the network behave in trustworthy manner otherwise detect and elimin...

In this study, a method for hierarchical examination and visualization of GSM data using the Self-Organizing Map (SOM) is described. The data is examined in few phases. At first temporally averaged data is used and then, in each phase some of the data is discarded and the rest is examined in more detail. The SOM is used both in clustering and in visualization. The actual clustering is performed...

Objective. To examine the performance and pre-competition psychological states of individual sport athletes in relation to competition location. It was hypothesized that skiers would perform better when competing at home. Self-reports of state anxiety were expected to be lower and self-confidence higher prior to home races compared to away. Design. Within-subjects design to examine athletes’ pe...

Since the early 1990’s, a variety of studies has shown that network traffic, both for localand wide-area networks, has self-similarity properties. This has led to new approaches in network traffic modelling because most traditional traffic approaches lead to the underestimation of performance measures of interest. Instead of developing completely new traffic models, a number of researchers have...
