Polarimetric Calibration

In the diverse applications of polarimetric Synthetic Aperture Radar (SAR) systems, it is a crucial to conduct polarimetric calibration, which aims to remove the radar system distortion effects prior to utilizing polarimetric SAR observations. The objective of this study is to evaluate the performance of different polarimetric calibration methods. Two widely used methods, the Van Zyl and Quegan methods, and one recently proposed method, such as the Villa method, have been selected among various calibration methods in literature. The selected methods have basic differences in their assumptions that are applied to the polarimetric system model. In order to evaluate the calibration performances under different system parameters and ground characteristics, comparative analysis of the calibration results were conducted on synthetic polarimetric SAR data and ALOS PALSAR quad-pol mode data. Based on the experimental results, the advantages and limitations of different methods were clarified, and a simple hybrid calibration method is presented to further improve the polarimetric calibration performance.

AbstractSince 2020, the tourism industry worldwide has been devastated as a result of the COVID-19 pandemic. Governments across the globe imposed strict national lockdowns in order to curb the spread of the pandemic, with negative effects on tourism. This forced many tourism companies and organizations to turn to virtual reality (VR) to survive. As a consequence, numerous tourism scholars began to question whether VR would replace conventional tourism after COVID-19. The study aims is to address this concern and to determine if VR will be a substitute for conventional tourism or whether it can be considered as a tourism niche. It is a conceptional study which adopts a comparative analysis of conventional tourism models and VR. It uses two popular conventional tourism models, namely N. Leiper’s (1979) tourism system model and R.W. Butler’s (1980) destination life-cycle model. Based on this analysis, this paper suggests that VR will never be a substitute for conventional tourism, but should rather be considered a future tourism niche.

Novel Method

In this paper we present a novel method for fault identification in Discrete Event Systems, which was developed using the classical diagnoser method. Our goal was to decrease as much as possible the amount of computation that needs to be done to generate a diagnoser and to use it for isolating faults. The proposed method consists in grouping the components of the plant in several types and to generate the plant model, the system model and the diagnoser for the “grouped plant”. In this way the size of the automata is reduced. The method is presented and tested on a loading station in a comparative analysis with the method without grouping

<p>This research aims at examining the holistic-integrative approach system model appliedto an Islamic Kindergarten in Purwokerto city, Banyumas Regency. This qualitative research employs acase study with observation, interview and documentation as the data collection techniques. The data are then analyzed using two analysis techniques, namely content analysis and comparative analysis, with an interactive cycle. Based on the findings, the education developed through thesystematic approach ranges from the input resourcesstrengthening process, processes and transformation of raw inputs involving process quality elements, setting output targets with clear and measurable characteristics, and orientation to education unit users. The Islamic Kindergarten’s system is formulated in an integrated holistic system format model of early childhood education (sources, environment, process, transformation, output, and user). The model is developed by the researcher out of Kaufman’s model and Smith’s modelfor general system approach model.</p>

General description of the research topic. The article presents a comprehensive study of traditional induction-dynamic mechanisms (with one disk and a fixed coil) and multi-core induction-dynamic mechanisms (linear pulse induction converters) with a movable coil and two disks. Actuality of the topic. Such induction-dynamic mechanisms are widely used in various fields, in particular, in electrical apparatus industry, where speed is one of the most important characteristics. The purpose of the article is a comparative analysis and refinement of the characteristics of the traditional induction-dynamic system with one disk and a fixed coil and multi-core one with a movable coil and two disks. Research method, scientific novelty. The calculations are based on the solution of the equations of the electromagnetic field and the equations for the electric circuit of the coil. Practical significance and main conclusions. During the calculations, the values of electromagnetic force and force impulse acting on the moving disk, energy losses in the system and electromagnetic energy of the system are determined. The results of the study are presented in the form of graphs, namely, the coil current and total magnetic energy for a traditional induction-dynamic mechanism with one disk and for multi-core one with two disks, Joule losses in a fixed coil and disk (in a traditional system) and in a moving coil and two disks (in a multi-core system), force impulse and electromagnetic force of a moving coil (in a multi-core system) and a moving disk (in a traditional and a multi-core system) total impulse of the moving parts of the induction-dynamic mechanism with a multi-core system, as well as the electromagnetic force and the total force acting on the moving parts of the induction-dynamic mechanism with a multi-core system. It is shown that the induction-dynamic mechanism with two disks is less effective in terms of electromagnetic force, impulse and electromagnetic energy than the induction-dynamic mechanism of the traditional layout.
