In this paper, we present an access network design problem with end-to-end quality of service (QoS) requirement. The problem can be conceptualized as a two-level hierarchical location-allocation problem on the tree topology with nonlinear side constraints. The objective function of the nonlinear...

This paper deals with a physical access network design problem of fiber-to-the-home passive optical network (FTTH-PON). The design of FTTH-PON access network seeks the cost effective location of optical splitters that provide optical connectivity from central office to subscribers in a given...

This paper analyzes the patent propensity as an outcome of innovative activities of regional SMEs. To achieve the aims, we apply robust regression analysis to estimate the models to test 5 research hypotheses using 263 firm level data located at Gwangju region in Korea. Our empirical results...

The external circumstances for universities have been changing rapidly. In order to be competitive, survive, and flourish, universities have shown a growing enthusiasm to generate financial revenues externally. The literature refers to this phenomenon as academic capitalism, defined as the...

In this research, we developed software for designing the optimum shape of multi-MW wind turbine blades and analyzing the performance, and it features aerodynamic shape design, performance analysis, pitch–torque analysis and shape optimization for wind turbine blades. In order to verify the...

Market multiples of the largest firms are most likely to reflect efficient pricing of stocks. For such firms, variations in market multiples should be largely explained by fundamental variables, and expected returns should be positively related to beta but not significantly related to other...
