Blind spots usually lead to difficulties for drivers to maneuver their vehicles in complicated environments, such as garages, parking spaces, or narrow alleys. This paper presents a vision system which can assist drivers by providing the panoramic image of vehicle surroundings in a bird’s-eye view. In the proposed system, there are six fisheye cameras mounted around a vehicle so that their views cover...
Time series prediction has been widely used in various fields. GEP is one of the popular methods for time series analysis. However, the GEP-based prediction models contain only one single function. To accurately capture the dynamic behavior of time series, this study develops a system which integrates multiple functions in a GEP-based model for time series prediction. The weight of each function is...
Evolutionary algorithms have proved to be a powerful tool for solving complex optimization problems. Imperialist Competitive Algorithm (ICA) is a new evolutionary algorithm. Although ICA has been widely applied to solve many engineering problems, the convergence behavior of ICA is rarely discussed. This paper studies how ICA's parameters affect its convergence behavior. Our results indicate that one...
Handling missing data is widely studied to make proper replacement and reduce uncertainty of data. Several approaches have been proposed for providing the most possible results. However, few studies provide solutions to the problem of missing data in extended possibility-based fuzzy relational (EPFR) databases. This type of problem in the context of EPFR databases is difficult to resolve because of...
This paper describes a composeable service platform that supports opportunistic collaboration among smart appliances deployed sporadically and incrementally in living and working spaces. This ubiquitous e-Helper's platform is UPnP based and is consisted of a three-level device/service abstraction and a protocol translation proxy. As the first experiment, the platform is used to perform indoor luminance...
