Opis:: Using a progressive information technologies for development of web-based courses and their administration brings a lot of practical and theoretical problems. We know web course problem is only small solution concerning construction of a large entire web-based e-learning environment. One of a practical problem is how to construct web-based electronic courses that have to meet international AICC standards. Implementation of such strict statements resulted in a lot of small or larger difficulties if we had used an elementary HTML editor. Using a special web course oriented editors can absolutely solve this problem. The second problem is construction of the web-based e-learning application that can administrate such web courses and takes into consideration AICC regulations. Development of such web applications is founded on the latest web technologies. This article introduces one approach to the modeling of the two most important components (web-based course, web-based application) of the web-based e-learning environment, convenient for Military Academy in Brno and Czech army. The article outlines the structure of web subject, e-learning environment and their implementation. The LMS's structure and its functionality, based on a snaps algebra, belong to important results of the article.

Opis:: This paper presents a time-saving method for monitoring the ecology of a dispersed territory using the delivery of measurement units provided by unmanned aerial vehicles with measurement sensors according to a reverse priority algorithm. It is achievable because of the decreasing mean waiting time of the order inside a queue during low-priority order servicing. The experimental research that confirms the efficiency of the proposed method in the case of delivery distributed measurement systems for low-priority measurement is carried out. The experimental research of the proposed method in the case of one-channel and many-channel SMD that can have an option of order rejection or an in-queue waiting option is conducted in WeBots. The probability distributions in the case of this system applying are compared with similar probability distributions in the case of systems of direct priority applying. Comparison and analysis enable us to conclude that the probability distribution in the case of SMD with a direct priority of delivery tends to decrease and approximates zero. This is related to the fact that means at the end of the queue to be handled have a lower priority, as these means of measurement take longer to handle the order than those at the head of the queue. Thus, the means of a low priority will be serviced in the last charge and there is a constant possibility that in some cases such orders will be rejected. The proposed method enables moderate this situation by using increasing the possibility of servicing the low-priority orders. The method can increase the efficiency of environmental monitoring and pollution emission control.

3TZ environment
Opis:: This paper presents the concepts and explores issues related to the 3 Time Zones (3TZ) model of software development in global workspace environment. The 3TZ model itself seeks to take advantages of differences in time zones between places around the world. By engaging software development teams in different regions separated by 8 hours each, it is possible for their combined working hours to cover the whole 24 hours period. Thus, while they each work their normal 8 hour days, together they are able to achieve in 1 day what a single team would achieve in 3 days. They are able to achieve this by passing on their work from one team to the next as one finishes their workday and the next team starts their workday. The 3TZ model of software development revolves around the employment of a software development team distributed in at least 3 different locations around the world in 3 different time zones. If work was passed on from one team to the next and adjacent teams were separated by 8 hours, then 24 hours continuous collaborative software development could be achieved. Though this poses many challenges, when dealt with there is great potential for software to be developed much faster than is possible for a single, collocated development team. In the global economy, we have seen a decrease in the barriers towards communication across the globe along with an increase of service availability to support this communication. Software development is one of the disciplines that is capable of effectively utilizing and benefiting from global collaboration prospect lent by ever increasing capability of information and communication technology. 24 hours continuous development is ideal for application towards tasks that have hard deadlines or require work completed as soon as possible. This article will mainly focus on introducing 24/7 global models that can be applied in cloud environment used in three different time zones.

Opis:: In this paper we describe a semi-automatic programming framework for supporting users with managing the deployment of distributed applications along with storing large amounts of data in order to maintain Quality of Service in highly dynamic and distributed environments, e.g., Grid. The Polish national PL-GRID project aims to provide Polish science with both hardware and software infrastructures which will allow scientists to perform complex simulations and in-silico experiments on a scale greater than ever before. We highlight the issues and challenges related to data storage strategies that arise at the analysis stage of user requirements coming from different areas of science. Next we present a solution to the discussed issues along with a description of sample usage scenarios. At the end we provide remarks on the current status of the implementation work and some results from the tests performed.
Artykuł opisuje semiautomatyczny szkielet aplikacyjny służący do wsparcia procesu wdrażania aplikacji oraz składowania dużych ilości danych w środowiskach rozproszonych z uwzględnieniem parametrów jakościowych. Projekt PL-Grid ma na celu wsparcie polskiej nauki w celu umożliwienia naukowcom przeprowadzania złożonych eksperymentów typu in-silico na skalę wiekszą niż dotychczas. W artykule zostały opisane wyzwania związane ze strategiami zarządzania wielkimi ilościami danych, zdefiniowane w fazie analizowania wymagań użytkowników projektu PL-Grid. Zostały również opisane proponowane rozwiązania omawianych problemów, opis przykładowych scenariuszy użycia oraz aktualny stan prac implementacyjnych i rezultaty przeprowadzonych testów.
