In this study an initial concept is described. This shows the possibility of connecting axially an ordinary jet engine, a ramjet engine and a scramjet engine. Furthermore rocket mode is also available in this design. The different modes can be changed by this integrated system as easily as the different modes, or nosecone stages can be changed by ordinary jet engines below and above the speed o...

In this paper we present the Lecta integrated education system. We show general assumptions of the system and we describe modules of Lecta. System programming platform, teaching aspect and exam module “Lecta-Egzaminator” are presented in detail.

All activities in an organisation require or produce information. Therefore, a document is not only the main information carrier but also the central aid for the integration of office functions I 1 I . The office of the future will be characterized by new fundamental tendencies which lie not only in a more comprehensive possibility for information interchange but also in an altered processing o...

Introduction: As spacecraft designs converge toward miniaturization and with the volumetric and mass constraints placed on avionics, programs will continue to advance the “state of the art” in spacecraft systems development with new challenges to reduce power, mass and volume. Although new technologies have improved packaging densities, a total system packaging architecture is required that not...

The purpose of computer forensic is to make digitalevidence which can be accepted in court using wellorganized technic and according to reasonable process in computer crime investigation. Recent forensic technic field is developed every year, however computer crime isn't. Especially, there are lacks of definite procedures such as collection, transfer, analysis of evidence, report evidence to th...

Previous discovery systems have successfully rediscovered known scientific laws . However, they have addressed only limited parts of the empirical discovery task . In this paper we introduce an integrated discovery system (IDS) which addresses many issues of empirical discovery. IDS operates in three stages : taxonomy formation, qualitative discovery, and quantitative discovery. We focus on the...

environmental monitoring and rest or at ion requires efficient access to large amounts of spatial information. the geographic information system (gis) and remotely sensed data are related to both physical and man-mad e features. in order to handle this task, the environmental scienc es section (ess) created the environmental data atlas (eda) that uses spatial keys to link all data sources to a ...
