Detached breakwaters are widely used for shore protection. The planforms of tombolos or salients behind structures have also been to provide a recreational and sustainable coastal environment. In this study, the comprehensive XBeach model was numerically simulate evolution wave transformation, nearshore current, morphological changes in tombolo detached breakwaters. Given various gap spacings between consecutive breakwaters, numerical results indicated that both equilibrium bay-shaped...

We used the liquid-based R2 rotational seismometer in addition to several arrays of translation velocity seismometers on a 12-floor building National Cheng Kung University campus evaluate dynamic responses structure. During observation period August-October 2023, we encountered moderate M 5.6 earthquake sequence 61 km north and one typhoon passing through this 49-m-long 12-m-wide building. By examining these data, investigate natural frequency rotation behavior long-strip-shaped Both...

Abstract The Meinong mainshock ( M L 6.6) occurred in southern Taiwan at 19:57:26.08 (UTC) on 5 February 2016. To study source characteristics of the mainshock, ground motions are simulated using empirical Green's function method to construct a strong motion generation area (SMGA) model. Records event 2 May 2010 4.6) chosen as functions along with six stations surrounding area. Waveforms all used utilizing best‐fit model by comparing synthetic waveforms observed ones frequency range 0.2–10...

The main goal of this study is to identify factors that might influence learners learn online actively based on the theories human brain, constructivism, rational behavior, innovation diffusion. There are 2,083 interviewers data collected from high schools in Taipei and Hualien. "Active Online Learning" Model has been constructed survey results by using structural equation modeling. analysis indicate perceive usefulness critical factor promote satisfaction web-based learning environment. A...

The goals of this study are to identify factors influencing the intention high-school students across Taiwan Straits participate in Web-based distance education (DE). MISS (Multi-faceted Internet Survey System) has been adopted collect data from 3,677 both China and Taiwan. All indicators study, such as availability school online courses, home computer environment, student skills also their practical experiences taking re-constructed based on each indicator's own set variables order evaluate...

It has currently become an important issue in searching for clean and sustainable renewable energy. Wave power is one of substantial energies. The oscillating water column (OWC) device the most extensively studies wave energy converter largest number prototypes so far deployed into sea. breakwater-integrated OWC been constructed successfully Sakata harbor Japan, Mutriku port Spain, Civitavecchia Italy etc. several advantages, especially much easier maintenance plant (Falcão Henriques,...

<p>In the past decade, there have been several disaster earthquakes occurred in Taiwan.<br>From observed data of earthquakes, stations located source<br>rupture direction obvious directivity pulses, and distribution earthquake<br>disaster is related to peak ground velocity. Therefore, how use a large high-<br>dense seismic database develop near-real-time detection system on earthquake<br>rupture directivity,...
