Navigation System of an Unmanned Boat for Autonomous Analyses of Water Quality
(Kaunas Univ Technology, 2013)
This paper presents a navigation system for autonomous analyses of water quality using unmanned boats at drinking water reservoirs such as dams and holding ponds. As it is well-known, water quality plays an important role ...
Analysis of doubly fed induction generator wind turbine system during one phase-to-ground fault
(2013)
This paper presents detailed analysis of doubly fed induction generator (DFIG) wind turbine electrical components during normal and unbalanced fault condition. Wind turbine components are individually modeled and then ...
Continuous wavelet transform for ferroresonance phenomena in electric power systems
(Elsevier Sci Ltd, 2013)
The common characteristics of a nonlinear system are multiple equilibrium points, limit cycles, jump resonance and sub-harmonic generation. Ferroresonance is also a nonlinear electrical phenomenon, which occurs frequently ...
Spectral and Statistical Analysis for Ceramic Plate Specimens Subjected to Impact
(Trans Tech Publications Ltd, 2013)
In this study, ceramic plate behaviour was elaborated on the basis at sound signal variations caused by the impact. All tests were performed using plate specimens and pendulum testing station; with date acquisition and ...
Free vibration analysis of asymmetric shear wall-frame buildings using modified finite element-transfer matrix method
(Techno-Press, 2013)
In this study, the modified finite element-transfer matrix methods are proposed for free vibration analysis of asymmetric structures, the bearing system of which consists of shear wall-frames. In the study, a multi-storey ...
The defect detection in ceramic materials based on wavelet analysis by using the method of impulse noise
(Jve Int Ltd, 2013)
In this experimental study, it was achieved to detect internal or surface cracks that can occur in the production of ceramic plates by using the method of impulse noise. This method is a test technique which was not used ...
Continuous Monitoring of Water Quality Using Portable and Low-Cost Approaches
(Sage Publications Inc, 2013)
Water quality refers to the physical, chemical, and biological characteristics of water, and it is a measure of the condition of water relative to any human need or purpose. A particular problem with measuring the condition ...
Free Vibration Analysis of Asymmetric-Plan Shear Wall and Core Buildings Using One-dimensional Finite Element
(Springer Heidelberg, 2013)
In this study, a method is presented for free vibration analysis of multi-storey asymmetric structures whose bearing system is composed of shear walls and cores. The multi-storey structure was modeled as an equivalent ...
Free Vibration Analysis of a Thin-Walled Beam with Shear Sensitive Material
(Hindawi Ltd, 2013)
This paper presents a method for a free vibration analysis of a thin-walled beam of doubly asymmetric cross section filled with shear sensitive material. In the study, first of all, a dynamic transfer matrix method was ...
Reliability Analysis of Hybrid Energy Systems: Case Study of Davutpasa Campus
(Ieee, 2013)
In recent years, sustainable and clean renewable energy resources are widely used instead of fossil fuel energy resources in electrical energy generation systems. Especially, wind and solar energy conversion systems are ...
