The ultimate goal of this work is to develop an image-based guidance system for a microrobot that treats vascular disease. In the preoperative stage, a computed tomography angiography (CTA) image is taken after fiducial markers are implanted. In order to obtain the position information of the microrobot during surgery, a biplanar fluoroscopic image is used. Fiducial marker-based registration is carried out to measure the relative position between CTA images and X-ray images, and it will be used to obtain the position information of the microrobot. Resultant error of the registration procedure was about 2 mm, and the image-based guidance system for the microrobot will be developed using the proposed algorithm.

Rotor Speed-based Droop of a Wind Generator in a Wind Power Plant for the Virtual Inertial Control

The frequency of a power system should be kept within limits to produce high-quality electricity. For a power system with a high penetration of wind generators (WGs), difficulties might arise in maintaining the frequency, because modern variable speed WGs operate based on the maximum power point tracking control scheme. On the other hand, the wind speed that arrives at a downstream WG is decreased after having passed one WG due to the wake effect. The rotor speed of each WG may be different from others. This paper proposes an algorithm for assigning the droop of each WG in a wind power plant (WPP) based on the rotor speed for the virtual inertial control considering the wake effect. It assumes that each WG in the WPP has two auxiliary loops for the virtual inertial control, i.e. the frequency deviation loop and the rate of change of frequency (ROCOF) loop. To release more kinetic energy, the proposed algorithm assigns the droop of each WG, which is the gain of the frequency deviation loop, depending on the rotor speed of each WG, while the gains for the ROCOF loop of all WGs are set to be equal. The performance of the algorithm is investigated for a model system with five synchronous generators and a WPP, which consists of 15 doubly-fed induction generators, by varying the wind direction as well as the wind speed. The results clearly indicate that the algorithm successfully reduces the frequency nadir as a WG with high wind speed releases more kinetic energy for the virtual inertial control. The algorithm might help maximize the contribution of the WPP to the frequency support.
PARTICIPATION AND PARTNERSHIPS IN URBAN REGENERATION AND CULTURAL TOURISM DEVLOPMENT
Jinsik Lee,Timothy Jung 세계문화관광학회 2009 Conference Proceedings Vol.10 No.0
This paper aims to explore to the extent the related stakeholders perceive culture's contribution to urban regeneration and to examine difficulties perceived on participation and partnerships among the stakeholders involved in Gwangju Project, Hub City of Asian Culture, as a case study of cultural regeneration project for urban regeneration and cultural tourism development in Korea. The qualitative interview is employed to collect data from multiple stakeholders associated with Gwangju Project and a total of 19 stakeholders who have involved both directly and indirectly in the project are participated. The results of this study suggest that public-private co-operation and collaboration in regeneration projects will give huge economic benefits to the associated stakeholders and socio-cultural impacts to Gwangju city. The study also reveals that there are gaps in terms of participation and partnerships between government and other associated stakeholders due to lack of opportunities and reliable evidence for active participation and close partnerships. To achieve these positive impacts in Gwangju Project, there needs to be closer working relationship between central-municipal government and public-private/voluntary sectors.
