The researchers aim to construct an emergency mobile phone charging station that runs on renewable energy and will serve as a cost-efficient alternative to more traditional power banks. Circuit components include a 20V / 6W solar panel supplemented by a hand-crank gear mechanism integrated with a 6V / 1A lead-acid battery, a usb output and an adjustable switch-mode power supply (SMPS) to convert excess voltage into current. Initial voltage and current outputs were measured under varying resistances. It was determined that the set-up satisfied the minimum voltage and current requirement for charging a mobile phone (5V / 1A). A subsequent phone charging test was executed using a Samsung Galaxy J2 (3.85V Li-ion battery 7.70W, Charge Voltage: 4.4V / 2000mAh) wherein it charged on an average of 0.277% per minute for the solar panel and an average of 0.263% per minute for the hand crank gear mechanism. A Mann-Whitney U statistical test was conducted to determine if the charging rate of the charging station had a significant difference from a commercially available power bank’s. The calculated UA: (4) from the test was below the lower limit and the UB: (217) was above the upper limit which indicated that there was a significant difference between the charging rates. While the efficiency was lower than the commercial power bank’s, it can still be used as an alternative charging method especially during emergencies and disasters.

兩條不平行的相交直線L1、L2，交角θ度。今有一不在L1、L2 的點P0，作關於L1的對稱點P1。P1又作關於L2的對稱點P2，P2又作關於L1的對稱點P3??如此反覆對L1、L2 做對稱點，當Pn 的n＝ 2π/g.c.d(π,Θ)，則Pn 會重合P0。另外對L1、L2 形成的所有對稱點會位在同一個圓上

本研究主要以一連串地震分析，來討論台灣地區地震能量釋放的型態。首先求出地震活動參數，接著再繪製地震規模的年發生率，最後推算台灣地區地震能量釋放時前餘震與主震所占之比重。在地震參數上，發現地震活動度較高的月份中，在該月都發生了芮氏規模六級以上的大地震，因其餘震發生的頻率較小震頻繁，因此造成其a 值較大。另外本研究發現，在大地震來臨之前，地震A 值會升高，應可視為其A 值升高之因是由於前震的關係。在地震規模年發生率方面，繪製出圖表，最後發現台灣地區地震仍以小震多，另外大地震則有一定週期。在研究最後，了解台灣地區地震常數之後，本研究更以ESRI 的GIS 軟體ArcView9.0 版輸出台灣地震目錄，並從中了解台灣的震測儀器發展。This research presents a series of earthquake analyses to discuss earthquake’s energy release type. First, we evaluated earthquake’s constant and charted the percentage of earthquake measurement every year. Finally, count the after-shocks and the major earthquake measuring 6.0 and above on the ML happening in Taiwan area. Because the after-shock frequency is more than light earthquakes, as a result it causes the“a” enumeration is large. According to the percentage of earthquake measurement happening frequency every year, we illustrate a chart. Finally we find that in Taiwan area mirror earth-quakes account for a large percentage and major earthquakes happened regularly. When we realize the constant of earthquake, the study folds a variety of layers by using ArcView 9.0 edition of GIS (Geography Information System) of ESRI , knowing the earthquake in Taiwan.

待宵花（Oenothera drumnondii Hook）屬於柳葉菜科（Onagraceae）、月見草屬（Oenothera）的植物，原產於北美洲，是金門的「歸化植物」。本項研究自 90 年 6 月至 91 年 5 月，就金門西南濱海地區待宵花族群分布及變化、生長環境與其形態上的適應進行調查。發現待宵花生長在海濱沙丘，其主要族群分布地有六處，以湖下海堤內的族群最大。族群密度在六月達最高峰，而在十二月時最小。4?8 月是待宵花盛開的月份，而 12?2 月則極少開花。待宵花對海濱沙地的生長環境適應性很強，經觀察發現它們以其植物體多種特殊的形態與構造生長在乾旱的沙地上，在金門海濱沙地少有植物可與它們競爭。

我們發現當CdS 與ZnS 重量比以2:1 時，能在Na2SO3 及Na2S 的混合溶液中，照射日光產生氫氣，並能有最佳的產率38.18(ml/hr*g)，比一般直接照紫外光的效果更好。不只善用自然界的太陽能，還可以生成最乾淨"綠色"的能源－氫氣。我們以 CdCO3 和ZnCO3 做為產氫觸媒的原料，其為黃色的粉末，並以AA 原子吸收光譜儀求得樣品溶液中測得CdS 與ZnS 重量比為２：１。 把產生的觸媒放入以 Na2S 和Na2SO3 混合而成的溶液中，以鋁薄紙包覆以防受光實驗提早進行。把實驗裝置放在日光下照射，以一端管口所接的細量管得失產生氫氣的體積，進而換算產率。 我們的實驗裝置為密閉式的，並無循環裝置，故產氫量有限。未來的發展將是朝著大型開放式的循環系統，使氫氣能源源不絕的產生。 The production of molecular hydrogen upon sunlight illumination of the mixture of CdS and ZnS suspensions in the weight ratio 2:1 in Na2SO3 / Na2S solution have been observed. The best rate of evolution of hydrogen is 38.18(ml/hr*g), which has a higher efficiency than upon UV illumination. It not only make a great use of the solar energy, but also produce the cleanest “green” energy resource─hydrogen.

Parameters of traffic, road availability, and fare were integrated into a web-based application for determining the best public transport routes within Metro Manila in order to assist commuters in their travel planning, whether for business or for pleasure. A user-friendly interface was developed to obtain a user’s place of origin and destination, as well as preferences in travel time, mode of transportation, and cost of journey. By accessing the traffic roadway network of the metropolis, a real-time situation of road availability was obtained, and used in a modified Dijkstra’s shortest-path algorithm to produce a model of a real-time adaptive transport network of Metro Manila. From the model, an optimal route that considers the user’s preferences can be determined. This project will be immensely useful in helping both businessmen and tourists in planning their routes that will save on time and money.

When predicting a hurricane’s landfall location, small improvements in accuracy result in large savings of lives, property, and money. The project’s purpose was to apply a breakthrough method that can predict the geographic location of a hurricane’s landfall with high accuracy. Researchers have known for a long time that there are strong correlations between a hurricane’s landfall location and the geographic regions its track passes through. However, no methods have been developed to mathematically and explicitly describe these correlations. Consequently, the correlations can only serve to meteorologists as vague guidelines for their guestimates and are not usable in making practical forecasts. By studying the correlations and performing numerical optimization on historical hurricane data, this research discovered a set of geographic belt regions in the Gulf of Mexico that can be used as landfall location predictors. When a hurricane passes through any one of these belt lines, a prediction can be made by extending the hurricane’s moving direction vector towards land – the intersection point of this extension line with the coastline is the predicted landfall location. This prediction method is simple and straightforward. It only uses basic measurements from meteorological satellites: the hurricane’s real-time locations and moving directions. In conclusion, when compared to existing methods, the predictive belt method (PBM) created in this research provides a landfall location forecast with higher accuracy. Verification with historical hurricane data demonstrated that the PBM’s average error is less than 50% of the National Hurricane Center models’ error.

In case of emergencies, it is an application which integrates location, tracking, and communication tools. It is triangulated between a database to a communication server as well as a second which is NASA server that offers climate and seismic information for Mexico. This application has two sources of communication, SMS messages and a newly created social network. In case of natural disasters, an extension for drones has been developed for this application, enabling rescue teams to delimit the land boundary where the disaster struck. In order to speed up the search and rescue operations a triangulation of network-drone- smartphone is completed.

The study aims to evaluate the technique of extracting water from humid air using solar energy through greenhouses in local areas. This technique is believed to provide limited amount of water in areas where potable water is not accessible or abundant. To solve this problem a pyramid-shaped device was designed, it is made of glass panels ad equipped with glass doors, fans operated by solar energy, and multiple shelves covered with fabric to act as Absorbent Calcium Chloride (CaCl2) with a 30% concentration. The doors are open during the night for absorption and closed during the day for energy-generating. Humidity, temperature, and atmospheric pressure are measured every two hours. The amount of water extracted in this area in one full day was around 3.0 liters a day for every square meter. Perhaps the limited amount of water is due to low level of humidity in the area: an average of 50% and temperature of F10 Celsius at night. However, the device itself is independent, does not need power sources, water sources, or infrastructure, can be installed in various places depending on humidity level as well as having the possibility of increasing number or size of device. This makes the device a promising, alternative and environmental friendly solution to produce water. Cost-effective and lighter material can be used to make the device, which will produce an easy-to-use and affordable devices. It is an area in need for further research to improve and further develop it.

This study investigated the production of novel molecular templates, and analyze their adsorption effect on four heavy metal ions (Cu+2, Pb+2, Zn+2, Mn+2), which commonly exist in Taiwan's rivers. Different operating conditions (such as competitive adsorption, pH value and other factors) were explored to compare their adsorption effect of heavy metal ions by using the synthesized template molecules. The molecular templates were found to be specific towards their target metal ions with a high adsorption effect. Then combined with the idea of magnetic particles to produce magnetic molecule templates, a maximum amount of adsorption of heavy metal ions up to 95% through the molecular template was achieved while the effect of heavy metals desorption of up to 83% could be also successfully obtained. Experimental results showed that the magnetic molecule templates did not affect the adsorption of heavy metal ions. Not only can they speed up the recovery time of adsorption but the template molecules can also be collected more efficiently. We also proposed three different applications for the developed molecular templates. The development of magnetic molecular template may provide an affordable, highly-efficient way for dealing with heavy metal pollutions.
