Development and application of offshore wind turbine farms have been increasing, particularly in the developed countries,because of their high power rating, high yield energy, high offshore wind, and unlimited space in the offshore. However, the poor data and simplistic methodologies of the previous assessments result in insufficient estimates of the wind energy potential.Thus, this study provides an assessment of the offshore wind energy resources in Malaysia using multi-mission satellite altimetry data. The satellite altimetry data was extracted from Radar Altimeter Database Systems located at GNSS and Geodynamics Laboratory, Universiti Teknologi Malaysia. The data were validated by buoy measurements from two offshore sites, as indicated by the high correlation coefficient of 0.88. Further, the offshore wind energy resource mapping data in Malaysia identified three areas in Peninsular Malaysia and Borneo as potential areas for offshore wind energy development. 相似文献

This article investigates the carpool mode choice option in the context of overall commuting mode choice preferences. The
article uses a hybrid discrete choice modelling technique to jointly model the consideration of carpooling in the choice set
formation as well as commuting mode choice together with the response bias corrections through the accommodation of measurement
equations. A cross-nested error structure for the econometric formulation is used to capture correlations among various commuting
modes and carpool consideration in the choice set. Empirical models are estimated using a data set collected through a week-long
commuter survey in Edmonton, Alberta. The empirical model reveals many behavioural details of commuting mode choice and carpooling.
Interestingly, it reveals that interactions between various Travel Demand Management (TDM) tools with the carpooling option
can be different at different level of decision making (choice set formation level and final choice making level). 相似文献

Abstract Hybrid choice modelling approaches allow latent variables in mode choice utility functions to be addressed. However, defining attitude and behavior as latent variables is influenced by the researcher's assumptions. Therefore, it is better to capture the effects of latent behavioral and attitudinal factors as latent variables than defining behaviors and attitudes per se. This article uses a hybrid choice model for capturing such latent effects, which will herein be referred to as modal captivity effects in commuting mode choice. Latent modal captivity refers to the unobserved and apparently unexplained attraction towards a specific mode of transportation that is resulting from latent attitude and behavior of passengers in addition to the urban transportation system. In empirical models, the latent modal captivity variables are explained as functions of different observed variables. Empirical models show significant improvement in fitting observed data as well as improved understanding of travel behavior. 相似文献
