INVESTIGATION OF ENTERPRISE ARCHITECTURE AND SOFTWARE ARCHITECTURE IN RELATION TO QUALITY ATTRIBUTES IN MILITARY APPLICATIONSB / JAN WEREWKA
Abstract. In this paper the relations between enterprise and software architecture are investigated. These relations may be different for a company which uses the software as part of their operation as opposed to a company which develops software systems. The relations are usually very complicated, therefore only the attribute of quality was chosen for this study. This paper shows the importance of finding mappings between quality attributes on enterprise architecture and software architecture levels. Some examples from the military domain are given. An interesting example used in the military is the survivability quality attribute, which has similar meaning on enterprise, system, and network levels. This paper proposes some ways in which the relations may be investigated.
MEASUREMENT ERRORS DETERMINATION USING IDENTIFICATION TECHNIQUES / MARTYNA ULINOWICZ, MARCIN ŻUGAJ
Abstract. Identification of measurement errors applied to UAV Cularis flight-test data is presented. Data preparation for identification process is considered as it often decides of the successful identification. The problem of data synchronization is solved on the signal processing level by introducing interpolation procedure before applying identification algorithm. The identification method based on quazi-linearization optimization technique together with relaxation strategy is implemented in Matlab environment in order to pursue simulation tests. The nonlinear airplane equations of motion are formulated in body –axis and only kinematic quantities are exploited. The preliminary simulation test results indicates successful identification of measurement errors.
