Training for information assurance

Abstract: In 2001, cadets from three military institutions built networks and defended them against a week of attacks led by the National Security Agency. The trial-by-fire exercise; which repeats in 2002, is a step toward preparing future network designers and administrators to think more strategically.

A step-by-step approach to social marketing in energy transition

Abstract: By examining social marketing this articles has featured a step-by step approach for residential behavioural change towards sustainable energy transition. Specifically, this article considers the value-based approach instead of rational information campaigns for behavioural change of energy users. The proposed framework is based on environmental values and designed to transform the selected destructive behaviour into a sustainable one. The framework consist of five steps: (1) selecting the behaviour, (2) user orientation, (3) exchange, (4) marketing mix: elements of intervention, (5) measuring behaviour change. As behavioural change is the final goal of any energy efficiency campaign, it becomes also a starting point and an objective of the rest of the activities in the framework. Second, we suggest using the user orientation concept that divides the society into three groups based on their attitude towards environmental issues, i.e. environmentalist, the environmentally concerned and the disinterested. In the third step we apply the exchange theory; whereas in the step of 'marketing mix' a conceptual combination of six elements for energy transition is reasoned: proposition, cost, communication, communities and partnership. Finally, the fifth step stresses on the measurement of the behavioural change that enables energy transition. The proposed step-by step framework is based on theory and builded on current practice in a field that is analysed in the article.

Checking of the methodical system efficiency of fitness technologies application in students' physical education.

Abstract: Objective The aim is to carry out a comparative analysis of the effectiveness of the traditional system of physical education of students in higher pedagogical education establishments and authors'methodical system of fitness technologies application. Patients and methods Materials and methods: Two hundred thirty two students of Zhytomyr Ivan Franko State University (n=232; 88 males and 144 females) aged from 18 to 20 years old took part in the research. Two experimental groups (EG, 47 males and 71 females) and two control groups (CG, 41 males and 73 females) were formed. Students were offered thefollowing modern types of fitness technologies: power fitness, aerobics, Pilates, swimming, yoga, tae-bo. Results Results: The positive effect of the authors' methodical system of fitness technologies application in comparison with the traditional system of physical education has been achieved - according to all the criteria of the research, the indicators of EG students (both males and females) are significantly better than those of the students from CG. Conclusion Сonclusions: It proves the necessity for the modern fitness technologies application in the educational process of physical education in higher education pedagogical establishments with the aim of improving the state of physical fitness, health of students and increasing their motivation for independent physical exercises and healthy lifestyles in the future.

Novel approach for laboratory calibration of star tracker

Abstract: An autonomous star tracker is an opto-electronic instrument used to provide the absolute three-axis attitude of a spacecraft utilizing star observations. The precise calibration of the measurement model is crucial, as the performance of the star tracker is highly dependent on the star camera parameters. We focus on proposing a simple and available calibration approach for a star tracker with wide field of view. The star tracker measurement model is described, and a novel approach for laboratory calibration is put forward. This approach is based on a collimator, a two-dimensional adjustable plane mirror, and other ordinary instruments. The calibration procedure consists of two steps: (1) the principal point is estimated using autocollimation adjustment; and (2) the other camera parameters, mainly the principal distance and distortions, are estimated via least-squares iteration, taking into account the extrinsic parameters. To validate this proposed calibration method, simulations with synthetic data are used to quantify its performance considering the errors of the distortion model and calibration data. The theoretical analysis and simulation results indicate that the uncertainties of the measured star direction vectors are less than 4.0×10−5 rad after calibration, and this can be further improved.
