Wavelet Methods

Abstract Vibration methods are used to identify faults, such as spanning and loss of cover, in long off-shore pipelines. A pipeline ‘pig’, propelled by fluid flow, generates transverse vibration in the pipeline and the measured vibration amplitude reflects the nature of the support condition. Large quantities of vibration data are collected and analysed by Fourier and wavelet methods.

This research was conducted Bangladesh (BD) and revised as an especial task study and review perspective of the coastal conditions and the features thus determine and critical analysis of integrated coastal zone management (ICZM). The coast length of Bangladesh is 710 kilometers wide. The coastal and ecosystem and habitats of the different animals are mostly depend on the features of coastal ecology and data analysis of both countries which have different strategies and techniques for the conservation of coastal biodiversity which were focused and brought together. Bangladesh coast contains vast biodiversity which are supported by the shingle beaches & sand dunes. The main features of the physical characteristics are the creeks, a lot of channels with crossing line, deltas of Ganges tidal plan with very low topology and mangroves. Integrated Coastal Zone Management (ICZM) in Bangladesh are greatly different because of variation in advanced and developed technology and the system of the creating legislative recommendations also varies; which could determine changes in sea level and coastal resources as well as habitats. This study targets to detect the background of coastal zone management (ICZM), scope, coastal development, challenges, environmental impacts, and necessary measures. Now, integrated coastal zone management (ICZM) is used for coastal development strategy in BD.

This study aims to analyze the existing performance of the Rose Florist agro-industry and formulate the business development strategy. This research uses a case study method with three respondents consisting of business owner, an employee of the business, and an UMKM officer. Data collection was carried out in April-May 2020. Data analysis uses cash flow and SWOT. The results showed that the Rose Florist Agroindustry has a good financial performance. There was an increase in cash of 9,538,729.17 from the cash flow statement, from the first period of IDR 153,249,128.57 to the second period of IDR 162,787,857.74. The development strategies that can be used in the development of the Rose Florist Agroindustry are to make quality flower arrangements, to add business signposts in business locations, and to train the workers on good management and better skills.

Abstract A fuzzy expert system was developed for autonomous in-space identification of spacecraft modal parameters. The in-space identification can be used to validate analytical predictions, detect structural damage, or tune automatic control systems as required. A fuzzy expert system determines accuracy of vibration data analysis performed autonomously using the Eigensystem Realization Algorithm. Evaluation of the data analysis output is imprecise and somewhat subjective. The expert system was developed using the knowledge provided the co-developer of the Eigensystem Realization Algorithm. The accuracy indicator represents the analyst’s degree of confidence in the analysis results. The fuzzy membership functions of the expert system were parameterized and tuned using numerical optimization.
