Top-coupled parallel-cascaded ring filter with transmission zeros

A pseudo-elliptic bandpass filter based on two top-coupled parallel-connected ring resonators is presented. Each ring contributes to the creation of two (2) poles leading to a 4th order response of the filter. Based on the topology, two (2) transmission zeros are obtained at both sides of the passband, ensuring the high selectivity of the filter. Centered at 2 GHz with 15% relative bandwidth a proof of concept of the compact filter topology is realized by using microstrip lines on epoxy glass substrate. The filter layout is presented in this paper along with the comparison between the simulation and measurement results.

PERCEIVED VALUE AND DESTINATION IMAGE ENHANCED ENVIRONMENTAL AWARENESS IN GREEN HOTEL INDUSTRY: THE MEDIATING EFFECT OF CORE COMPETENCIES

This study proposed an integrated theoretical model of hotel industry’s green core competencies. An empirical assessment of the theoretical framework for this study included a survey of 337 guests in Malaysian certified green hotels. The resulting data were analyzed using the Partial Least Square Consistency (PLSc) method using the SmartPLS 3.0 software. The findings indicated that perceived values and core competencies have a positives significant effect toward destination image. The competencies also give a positive significant effect toward destination image. All targeted variables were all contributed to improving understanding the underlying relationships. In addition, the study also confirms that core competencies had partial mediation effects between perceived value and destination image. Green hotel investment for the development of core competencies in green segments was helpful to hotel industry for the enhancement of perceived value and destination image.
